Description
[technical field]
The utility model relates to one and covers car device, especially relates to a kind of air door front and back and fixedly covers car device.
[background technology]
According to the regulation of " safety regulations in coal mine " the 118 article, in belt heading, air door should be set, can make pernicious gas isolation by air door, but the track in air door bottom can closely be placed mine car conventionally temporarily, prevent that mine car or air door collision personnel and mine car from breaking the safety measure of air door so should have; The car mode of mainly covering adopting at present before and after the coal seam underground air door of Yong Mei group is the portable two-way car device of covering.This portable car device of covering only uses in gallery parking lot, and must be to cover car after mine car stops again, and in locomotive is advanced, cannot cover car.Also having one to cover car device is to fix in orbit, cannot pass through and cover car conversion object by moving or take off to realize, just cover car device for long-standing ban vehicle pass-through, and it is undesirable to cover car effect, both can fix in orbit to realize and fixedly covered car object so be necessary to research and develop one, can also realize track by the mode of taking off unimpeded; Or conversion place track realize current and cover that car converts at any time cover car device.
[summary of the invention]
In order to overcome the deficiency in background technology, before and after the utility model discloses a kind of air door, fixedly cover car device, it is by the L shaped jam plate of gemel connection, rail is locked that car device both sides are covered in utilization, when use, can easily fix, the used time is not screwed and can easily be taken off by bolt, and the utility model has good effect for the safety that promotes mine shaft conveyance system.
For achieving the above object, the utility model adopts following technical scheme:
Before and after a kind of air door, fixedly cover car device, comprise and cover car device, L shaped jam plate, bolt and hinge, the described bottom, dull and stereotyped front and back of covering car device is respectively equipped with downward extension board, the described dull and stereotyped top of covering car device is provided with casting lug thereon, be respectively arranged with the arc-shaped recess that the is "eight" shape face of keeping off a car in the both sides of casting lug thereon, the middle part of two L shaped jam plates is respectively by the upper side both sides of gemel connection flat board, the flat extension board of two L shaped jam plate bottoms is disposed on the bottom of described flat board, and the top of two L shaped jam plates is respectively equipped with the bolt withstanding on casting lug thereon front-back.
Before and after described air door, fixedly cover car device, be provided with through hole on the top of casting lug thereon, the casting lug thereon upper end on described through hole top forms upper handle plate.
Before and after described air door, fixedly cover car device, be respectively equipped with two screws on the top of two L shaped jam plates, four bolts withstand on the front-back of casting lug thereon through after two screws of two L shaped jam plates respectively.
Before and after described air door, fixedly cover car device, the arc-shaped recess face of keeping off a car of described casting lug thereon both sides is the narrow "eight" shape structure of bottom wide upper portion.
Owing to having adopted technique scheme, the utlity model has following beneficial effect:
Before and after air door described in the utility model, fixedly cover car device, the flat board of car device is covered in utilization and two downward extension boards of dull and stereotyped bottom block rail, L shaped jam plate by covering car device both sides gemel connection is by locked the top of rail, facilitate that long-term no thoroughfare for vehicles, when use, can easily take off the utility model by unclamping bolt; The utility model has good effect for the safety that promotes mine shaft conveyance system.
