Abstract
The utility model provides a hydraulic tension device for a scraping chain, which is characterized in that the hydraulic tension device consists of a tension oil cylinder, an accumulator, a one-way choke holder and a guide rail mounted on at the lower part of a scraping baseplate and on the frame of a spreading machine, wherein, the accumulator and the tension oil cylinder are communicated with each other through the one-way choke holder, the guide rail is mounted on the frame, the bearing support of a scraping chain driven chain wheel is mounted in the guide rail, the piston rod of the tension oil cylinder is propped against the bearing support, and the tension oil cylinder is fixed on the frame through a supporting plate and a positioning plate. When the chain is relatively tight, part of oil in the oil cylinder is pressed into the accumulator for energy storage, and the oil cylinder retracts so the tension is relieved; and when the chain is relatively loose, part of oil in the accumulator is pressed into the oil cylinder, and the oil cylinder pushes so as to tighten the chain. The utility model provides the device with a simple structure, and achieves the purposes of tensioning the chain automatically, reducing abrasion among the chain, the chain wheel and the bearing, and prolonging the service life of the machine. Moreover, the utility model contributes to convenient operation and greatly reduced labor intensity.
Description
Technical field
The utility model relates to a kind of paver scraper chain Hydranlic tensioner.
Background technology
Current, the paver scraper chain tension that uses in the construction of the highway generally adopts artificial screw rod tensioning mode, but the tensioning limited length of screw rod, when chain is relaxed to a certain degree, have only remove chain link and block after tensioning again.Simultaneously, the rate of tension of chain has direct influence to the life-span of chain and sprocket wheel, and rate of tension is excessive, quickens the wearing and tearing of chain, sprocket wheel and bearing; Rate of tension is loose excessively, occurs stinging chain easily, falls chain, phenomenon such as get stuck.In addition, because screw rod is installed in the preceding bottom of paver, screw rod is easily polluted by the pitch material, or is damaged, and has more increased the difficulty and the intensity of tensioning work.
Summary of the invention
The purpose of this utility model provides a kind of paver scraper chain Hydranlic tensioner of simple in structure, dependable performance, to overcome the deficiencies in the prior art.
The technical scheme that solution the utility model problem is taked is: it is made up of tensioning hydro-cylinder, accumulator, individual event restriction choke and guide rail, be installed on the frame of scraper base plate bottom, paver, accumulator and tensioning hydro-cylinder communicate by the one-way throttle device, guide rail is installed on the frame, and the bearing support of scraper chain driven sprocket is installed in the guide rail; The piston rod of tensioning hydro-cylinder withstands bearing support, and tensioning hydro-cylinder is fixed on the frame through gripper shoe and location-plate.
Good effect of the present utility model is: simple in structure, can realize the chain auto-tensioning, and reduced the wearing and tearing of chain, sprocket wheel and bearing, prolonged the application life of machine; Not only easy to operate, also greatly reduce labor intensity of operating personnel.
Description of drawings
Accompanying drawing is an one-sided configuration schematic diagram of the present utility model.
The specific embodiment
As shown in Figure 1, it is made up of tensioning hydro-cylinder 5, accumulator 8, individual event restriction choke 7 and guide rail 2, be installed on the frame 10 of scraper base plate bottom, paver, accumulator 8 is fixed on the frame 10 through a fixed mount 9, communicate by one-way throttle device 7 with tensioning hydro-cylinder 5, guide rail 2 is installed on the frame 10, and the bearing support 3 of scraper chain 1 driven sprocket is installed in the guide rail 2; The piston rod of tensioning hydro-cylinder 5 withstands bearing support 3, and tensioning hydro-cylinder 5 is fixed on the frame 10 through gripper shoe 4 and location-plate 6.
During tensioning scraper chain 1, close the stop valve on the hopper oil cylinder with the scraper chain the same side that needs tensioning, pressure testing flexible pipe one end is connected with the pressure testing joint of hopper oil cylinder, the other end is connected with the pressure testing joint of one-way throttle device 7, under engine idling condition, by closing hopper oil cylinder button, pressure oil enters tensioning hydro-cylinder 5 and accumulator 8, tensioning hydro-cylinder 5 pushes bearing support 3 and moves forward along guide rail 2, with 1 tensioning of scraper chain.Because accumulator 8 and tensioning hydro-cylinder 5 communicate, when scraper chain 1 was tight, the part fluid in the tensioning hydro-cylinder 5 was pressed into accumulator 8 accumulation of energys, tensioning hydro-cylinder 5 retractions, and tensioning is alleviated; When scraper chain 1 was loose, the part fluid in the accumulator 8 was pressed into tensioning hydro-cylinder 5, tensioning hydro-cylinder 5 pushing tows, 1 tensioning of scraper chain.
