3. How to maintain asphalt paver
The paver will be parked for a long time and should be maintained according to the following requirements: (1) Carry out technical maintenance and antirust treatment for long-term parking according to the requirements of the instruction manual.
(2) Clean the internal and external surfaces of the machine, hopper, screed, spiral distributor and scraper conveyor. Should try to park in the warehouse; If it is placed in the open air, it should be placed in a ventilated place and covered with canvas.
(3) Use wood blocks to pad screed. (4) The hopper and leveling cylinder should be completely restored and coated with grease.
(5) When parking for a long time, the main engine can only be equipped with the basic section of ironing device and distributing device. (6) After cleaning, the random accessories of the paver should be properly rustproof and placed in a clean and ventilated room.
(7) Add new lubricating oil or grease to each lubricating point of the paver.
4. What are the functions of the cement concrete pavement paver?
Cement concrete pavement paver is a self-propelled unit used for cement concrete pavement or airport cement concrete pavement construction, which has the functions of paving, vibrating and leveling concrete mixture.
There are two types: track mode and sliding mode. Crawler pavers usually consist of a series of stand-alone machines, such as distributors, tamping machines and plasterers. Each machine has steel wheels that can move back and forth on the same track template. When working, it is similar to an assembly line to complete the laying of concrete slabs, so it is called laying trains.
According to the distribution mode of the cloth machine, it can be divided into scraper type, spiral type and box type. The scraper is used to level the concrete mixture discharged on the ground through the scraper which can rotate around its own axis and move left and right; The screw system adopts two independent reverse screw feeders to make the work stable; The distribution of box-type materials is carried out through the silo that can move transversely along the track.
Slip-mode paver has the functions of paving, tamping and leveling, so concrete can be continuously paved without vertical formwork. It is developed after the crawler paver, and can pave kerbs at the same time, but the supply requirements of raw materials, their mixture ratio and mixing are very strict.
5. What are the working devices of asphalt concrete paver?
The asphalt concrete pavement paved by paver must be pre-compacted, reshaped and ironed according to the thickness and arch requirements.
This operation is realized by the vibrating beam-screed device on the paver. (1) Vibrating beam mechanism The vibrating beam, also known as the "ram", is installed at the front of the screed.
Before the concrete enters under the screed, it is preliminarily compacted by vibrating beam. The power of the vibrating beam is provided by the hydraulic motor 2, which drives the driving shaft 4 to rotate through the belt.
The vibrating beam 5 is mounted on the driving shaft through a bearing 6, and the axis of the bearing has a certain eccentricity with the axis of the driving shaft. When the driving shaft rotates, the eccentricity can drive the vibrating beam to move up and down, which will impact and compact the concrete.
The vibrating beam is a plate beam structure, which consists of two pairs of members with the same structure and is driven by an eccentric shaft to move vertically up and down. The eccentric shaft is also left and right, and its inner ends are hinged into a whole and installed on the traction frame of the ironing device.
The phase difference of eccentric wheels on the left and right shafts is 180, so that both sides of the vibrating beam can be tamped and paved alternately up and down during work. (2) Ironing device The ironing device consists of an ironing board, a traction arm, a thickness regulator, an camber regulator and a heater.
Vibration ironing device is a vibrator attached to the ironing board, which can play the role of vibration compaction and overall ironing at the same time. The screed is a two-box structure welded by steel plates, and it is internally equipped with an arch adjuster, which cooperates with the thickness adjuster to adjust the cross-sectional shape of the pavement.
The screed and the vibrating beam are hinged to the special brackets on both sides of the frame or the hydraulic cylinders of the automatic leveling device through the left and right traction arms. Most thickness adjusters are screw adjusters on the old paver, while the new paver is hydraulic: the screed can be heated by flame or electric heating.
6. What are the uses of cement concrete paver?
Cement concrete paver can be used in the design of narrow cement roads in mountainous areas, rural towns and other places, with strong climbing ability. Widely used in narrow road construction limited by environment. Using electrical switch control, it is easy to use, stable to walk, widely used and widely praised by users.
Straightener is mainly composed of frame, diesel engine (motor), walking roller, vibrating roller, transmission system and control mechanism. Its design principle is to use the driving force generated by the vibration engine (motor) and the walking engine (motor) to drive the system, which is transmitted to the vibration roller and the walking roller respectively, and the cement concrete is compacted at high speed through the eccentric action of the vibration roller. The adhesion of the two walking rollers to the template provides driving force for the whole machine to move forward and backward, thus achieving the purpose of making the whole machine walk automatically.
7. Are there any tips for the technical maintenance of pavers?
Technical maintenance of paver;
Maintenance can be roughly divided into three parts:
1, part of which is daily technical maintenance, that is, the operator can reasonably maintain, routinely overhaul, regularly maintain and correctly operate the machine during use, which can prolong the service life of the machine and improve the use effect of the machine;
2. The other part is periodic technical maintenance, that is, the maintenance content that the operator's own conditions and means can't solve, such as the repair or replacement of the main parts of the machine, the medium repair and overhaul after a certain period of use, and the detection and adjustment. Be sure to go to the maintenance point designated by the specialized manufacturer and ask professionals to repair it.
3. Finally, the technical maintenance of long-term parking. Because pavers are different from other machines, especially in Qinghai, they are basically parked in winter, so they should be maintained.
Paver is a specialized production tool with high technical content and relatively complex structure. General working conditions are relatively harsh, and the technical level and professional knowledge quality of operators are quite different. In the process of use, due to the gradual wear of moving parts of various parts and the influence of various external operating conditions, the mechanisms and parts of various parts will inevitably become naturally loose and mechanically damaged to varying degrees, which will lead to the deterioration of the power and economy of the paver, reduce the safety and reliability of parts, lead to unexpected mechanical failures and affect the service life of the paver. Therefore, in order to improve the service life and reduce the occurrence of mechanical failures, maintenance work should be done well. Therefore, in the use and management of pavers, maintenance is essential.
