Abstract
The utility model provides a mine dumper box tip-back door plate automatic opening and closing device. The technical scheme is that a dumper wagon body, a tip-back door plate, a clamping plate device and a tension spring are fixed on the dumper box; the tip-back door plate is connected on the dumper wagon body through pin shafts, the clamping plate device is connected on the bottom of the dumper wagon body through the pin shafts and the tension spring; and a pre-tightening device is fixed on a dumper chassis, and the clamping plate device is connected with the pre-tightening device through a chain so as to form the whole device. The mine dumper box tip-back door plate automatically opening and closing device has the advantages of being capable of automatically tightly clamping and loosening the tip-back door plate of the dumper box, avoiding the possibility of being bent because of being pressed by materials during discharging, reducing maintenance time and maintenance cost, and improving work efficiency.
Description
Technical field
It is a kind of quarry tipper that the utility model relates to, particularly a kind of back overhead door board automatic opening-closing device of quarry tipper railway carriage.
Background technology
Widespread usage along with mining railless free-wheeled vehicle and some mining light card dumping cars, in the process of quarry tipper transportation and discharging, the back overhead door plate part of back overturning case is not have automatic clamping body, utilize and manually realize chucking back overhead door plate, its weak point is that manual gripping mechanism has strengthened work capacity, reduced conveying efficiency, material from leakage such as coal is transported safely the road surface in the tunnel certain hidden danger is also arranged in addition; Also having quite a few is to utilize push rod device to realize that back overhead door plate tightens automatically, and when its weak point was discharging, the push rod of stretching out was bent by materials such as coals easily and is out of shape, and increases maintenance time and cost, also can reduce work efficiency.
Summary of the invention
The purpose of this utility model is the deficiency that exists in the above-mentioned technology, and overhead door board automatic opening-closing device behind a kind of quarry tipper case is provided.Can realize tightening and relaxing automatically the back overhead door plate of dumper skip, the possibility of being bent by material in the time of also avoiding owing to discharging has reduced maintenance time, has reduced maintenance cost, has also improved work efficiency.
The purpose of this utility model is achieved in that and comprises dumper skip, back overhead door plate, gripping mechanism, extension spring, chain, pre-tightening apparatus.It is characterized in that dumping car railway carriage, back overhead door plate, clamp dress and extension spring all are fixed on the dumping car railway carriage; Back overhead door is connected on the dumping car railway carriage by bearing pin, and clip arrangement is connected dumping car railway carriage bottom by bearing pin and extension spring; Pre-tightening apparatus is fixed on the chassis, and clip arrangement and pre-tightening apparatus link together by chain, forms whole device.
The utility model has the advantages that, can realize tightening and relaxing automatically the back overhead door plate of dumper skip, the possibility of being bent by material in the time of also avoiding owing to discharging has reduced maintenance time, has reduced maintenance cost, has also improved work efficiency.

Fig. 1 is structural representation of the present utility model
Fig. 2 is structure enlarged drawing of the present utility model
Fig. 3 is use view of the present utility model
The specific embodiment
Below in conjunction with accompanying drawing present embodiment is described further
By Fig. 1-2 as can be known, structure of the present utility model is made of dumping car railway carriage 1, back overhead door plate 2, clip arrangement 3, extension spring 4, chain 5, pre-tightening apparatus 6.Dumping car railway carriage 1, back overhead door plate 2, clip arrangement 3 and extension spring 4 all are fixed on the dumping car railway carriage; Clip arrangement 3 and pre-tightening apparatus 6 link together by chain 5, form whole device.Back overhead door plate 2 is connected on the dumping car railway carriage 1 by bearing pin, and clip arrangement 3 is connected dumping car railway carriage 1 bottom by bearing pin and extension spring 4; Pre-tightening apparatus 6 is fixed on the chassis, and clip arrangement 3 and pre-tightening apparatus 6 link together by chain 5, form whole device.
When dumper skip 1 did not need to unload transported material, back overhead door plate 2 was strained and fixed by clip arrangement 3, chain 5 and pre-tightening apparatus 6, and the material in the dumper skip 1 can not leaked, and kept the travelling position of safety; When the needs discharging, start and turn over after the hydraulic pressure elevating ram makes dumper skip 1 slowly, just begun to start moment, the chain 5 that is in tight state unclamps suddenly, along with the lifting of oil cylinder is slowly relaxed, follow extension spring 4 to begin to strain clip arrangement 3 simultaneously, it is rotated toward opposite sense, satisfy clip arrangement 4 prior to relying on the action of the back overhead door plate 1 that deadweight opens, realize discharging, after unsnatching material, dumper skip 1 is in the process of slowly getting back to original position, because the action of clip arrangement 3 is subjected to the control of chain 5, just got back to original position from dump box 1, after back overhead door plate 2 is also just got back to original position simultaneously, after chain 5 is also strained thereupon, clip arrangement 3 begins action chucking back overhead door plate 2, in the action of back overhead door plate 2, realizes the travelling position of safety after realizing.Clip arrangement 3 and pre-tightening apparatus 6 link together by chain 5, form whole device.
The following dumping car of this device using method is at first tightened pre-tightening apparatus 6 before work, tension chain 5 can be transported safely and safe discharging after making clip arrangement 3 chucking back overhead door plates 2.
