Description
Technical field
The utility model relates to a kind of drive safety support.
Background technology
Colliery cave-in accident one is all number one killer in coal mining accident always, and the drive in colliery caves in, and the keeping of inside, colliery directly can be caused not enough, cause the workman's death by suffocation in mine work.
Therefore in drive, increase supporting is a kind of means that effectively can solve drive cave-in accident and occur, existing supporting is mostly the weldable steel component of customization, its height supported cannot regulate preferably, when there is gap between the top and drive of supporting, the pressure caused when drive caves in indirectly acts on the surface of supporting, cause larger impact force to supporting, cause the flexural deformation of supporting.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of drive safety support, and this device has good slow-release function, effectively reduces the power that produces when drive caves in the infringement of this device, extends the application life of this device, improve durability simultaneously.
For solving the problem, the utility model adopts following technical scheme:
A kind of drive safety support, comprise bearing component and supporting component, described bearing component comprises load-bearing girder steel and load-bearing floor, described load-bearing girder steel is T-shaped steel part, its top has the weight-bearing surface of an arc, described load-bearing floor is welded on the both sides of described load-bearing girder steel, the bottom of described load-bearing girder steel is provided with two adapter sleeves, described supporting component comprises support bar and base, the top of described base has the shrinkage pool that is held described support bar, the spring relative with described support bar is provided with at the bottom of the hole of described shrinkage pool, bolt is fastened with between described base and described support bar, described support bar is set in described adapter sleeve away from one end of described base.
As preferred technical scheme, described support bar and described adapter sleeve are welded and fixed, and described support bar is hollow steel pole, and the upper and lower end of described support bar is closed.
As preferred technical scheme, the distance between described support bar and described spring is 0 ~ 20mm.
As preferred technical scheme, described bolt is provided with two or more.
The beneficial effects of the utility model are: this device bears the pressure from drive top by load-bearing girder steel, when drive cave in or falling rocks accident time, supported by support bar, when support bar bearing capacity is excessive, bolt is destroyed, at this moment support bar acts on spring, slowly-releasing pressure, then remake and be used on base, this device has good slow-release function, effectively reduce the power that produces when drive caves in the infringement of this device, extend the application life of this device, improve durability simultaneously.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Consult a kind of drive safety support shown in Fig. 1, comprise bearing component 1 and supporting component 2, described bearing component 1 comprises load-bearing girder steel 101 and load-bearing floor 102, described load-bearing girder steel 101 is T-shaped steel part, its top has the weight-bearing surface of an arc, described load-bearing floor 102 is welded on the both sides of described load-bearing girder steel 101, the bottom of described load-bearing girder steel 101 is provided with two adapter sleeves 103, described supporting component 2 comprises support bar 201 and base 202, the top of described base 202 has the shrinkage pool 203 that is held described support bar 201, the spring 204 relative with described support bar 201 is provided with at the bottom of the hole of described shrinkage pool 203, bolt 3 is fastened with between described base 202 and described support bar 201, described support bar 201 is set in described adapter sleeve 103 away from one end of described base 202.
A preferred embodiment in the utility model, described support bar 201 is welded and fixed with described adapter sleeve 103, and described support bar 201 is hollow steel pole, and the upper and lower end of described support bar 201 is closed.
A preferred embodiment in the utility model, the distance between described support bar 201 and described spring 204 is 10mm.
A preferred embodiment in the utility model, described bolt 3 is provided with two or more.
The beneficial effects of the utility model are: this device bears the pressure from drive top by load-bearing girder steel, when drive cave in or falling rocks accident time, supported by support bar, when support bar bearing capacity is excessive, bolt is destroyed, at this moment support bar acts on spring, slowly-releasing pressure, then remake and be used on base, this device has good slow-release function, effectively reduce the power that produces when drive caves in the infringement of this device, extend the application life of this device, improve durability simultaneously.
The above, be only detailed description of the invention of the present utility model, but protection domain of the present utility model is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should limit with claims is as the criterion.
