Abstract
The utility model relates to an automatic tensioning hydraulic device for a scarper chain and a hydraulic material harrow drive system with the automatic tensioning hydraulic device. A power oil pipe of the hydraulic device is sequentially connected with a relief valve, an electromagnetic reversing valve, a hydraulic control one-way valve and one end of at least one chain tensioning cylinder, and the other end of the chain tensioning cylinder is connected with one oil return pipeline. The oil return pipeline is provided with an energy accumulator. All defects of the conventional manual screw tensioning method are eliminated completely, changes in tensioning pressure are detected by a pressure relay, and when the pressure is lower than the set value, the tensioning pressure is supplemented automatically, and the pressure is maintained by the hydraulic control one-way valve. Due to the energy accumulator and the effects of pressure maintenance and vibration absorption, the scraper chain tensioning force can be maintained constant within a certain range, and vibration produced in engagement of links of the scraper chain and a gear can be absorbed, so that the chain can operate more smoothly, and the service life of the chain can be prolonged. No frequent manual fastening is needed. In order to facilitate actual arrangement and simplify equipment modification during the preparation period on the site, the hydraulic pressure source is obtained from a material harrow driving power source according to the scheme.

The specific embodiment
Fig. 1 has shown the utility model flight chain auto-tensioning hydraulic efficiency gear system liquid pressing system principle: be linked in sequence reducing valve 10, solenoid directional control valve 11, hydraulic control one-way valve 12 of pressure oil pipe links to each other with the end of a chain tension oil cylinder 13a, 13b at least.The oil outlet of hydraulic control one-way valve 12 also connects pressure relay 15 and compression indicator 16 respectively.The other end of chain tension oil cylinder 13a, 13b connects oil return line.Also be provided with energy storage 14 at oil return line.Board-like ball valve 17 also can be housed between energy storage 14 and the oil return line.
Among Fig. 2, claw fluid power system main element comprises: fuel tank 1, oil pump 2, check valve 3, compression indicator 4, differential electro-hydraulic reversing valve 5, claw oil cylinder 6, electromagnetic relief valve 7, Air cooler 8, oil return oil filter 9.They are linked in sequence into system circuit.Draw the pipeline of connecting aforementioned flight chain auto-tensioning hydraulic efficiency gear power oil by the check valve 3 oil outlet P places of claw drive system, and the pipeline of this flight chain auto-tensioning hydraulic efficiency gear oil return is linked in sequence at T place and Air cooler 8, oil return oil filter 9.The claw driving pressure is 12MPa.The I that frame of broken lines goes out among Fig. 2 partly representes the principle of the utility model flight chain auto-tensioning hydraulic efficiency gear, i.e. represented part among Fig. 1.This a part of principle of work is: as previously mentioned, draw pressure oil by the oil outlet P place of original claw drive system check valve 3, through reducing valve 10 pressure is adjusted to 8MPa; By the tensioning of solenoid directional control valve 11 control tensioning hydro- cylinder 13a, 13b with unclamp; Guarantee the tensioning pressure no leak by hydraulic control one-way valve 12.13a, 13b are that actuating unit is the chain tension oil cylinder, are tensioning state when stretching out.Energy storage 14 is assisted pressurize and absorbing vibration, when tensioning pressure is lower than setting value 8MPa, sends signal by pressure relay 15, and system's auto-tensioning is to setting value.Compression indicator 16 is in order to visual observations tensioning pressure value.Board-like ball valve 17 can manually release tensioning pressure.Original claw drive system is guided in the total system oil return.
Fig. 3 contains in the position of components and piping layout scheme drawing of claw fluid power system of the utility model flight chain auto-tensioning hydraulic efficiency gear.Energy storage 14 is installed on the fuel tank side.Sequence number is that 10,11,12,15,16,17 part integrates to tensioning valve group, also is installed on the fuel tank side.13a13b is the chain tension oil cylinder.6 is original claw oil cylinder.
Among Fig. 4,18 is the Hydraulic Station position, and 19 is claw mechanism, and 20 are defeated material belt mechanism, and II is the position of chain tension oil cylinder 13a, 13b.
Fig. 5 is the enlarged drawing at II position among Fig. 4.13a, 13b are the chain tension oil cylinder, and two oil cylinders are installed side by side.The principle of the utility model is: the chain tension oil cylinder of this device is installed in the stressed position of stretching device; By the hydraulic efficiency pressure system propulsion source pressure oil is provided; Distribute two chain tension oil cylinders (also can control single oil cylinder respectively, below all explain) simultaneously through the pipeline threeway, when tensile force reaches when needing tension value by controlling two oil cylinders simultaneously; System stops to provide pressure oil, is keep-uped pressure automatically by hydraulic control one-way valve 12.At ordinary times by pressure relay 15 detected pressures values, pressure relay 15 can send signal when insufficient pressure (causing that pressure reduces because initial stage operation chain can elongate), and ftercompction automatically up to reaching setting value, stops pressurization.The utility model is equipped with energy storage 14 in addition, and this device can play absorption pressure fluctuation pulse, reduces the entire equipment vibrations, and it is big to have solved fluctuation of pressure, causes the chain breakage problem.
The hydraulic efficiency power unit of above-mentioned utility model can be to be equipped with alone, also can drive propulsion source from the reclaimer claw and obtain, and simple for the convenient and on-the-spot scrap build in early stage of actual arrangement, this novel employing drives the scheme that propulsion source obtains pressure source from claw.The electric-control system of this scheme comprises 1 pressure relay, 1 three position four-way directional control valve, 1 time delays relay etc.By change-over valve control tensioning and unclamp, send signal by pressure relay 15 (when being lower than setting value) and give PLC, pressurization.The time delays relay was delayed time about 2 seconds, to guarantee that moulding pressure a little more than the pressure relay setting value, can cause the phenomenon of pressurizeing often in order to avoid the slight pressure change occurs.
