Abstract
The present invention relates to a kind of coal working face branch bridge joint cash device, including mounting bracket and cash plate is connect, the top of the mounting bracket is provided with mounting hole, inclined plate is formed after bottom fold, the inclined plate and horizontal direction form angle, and the cash plate that connects is welded on inclined plate, is arranged in parallel with inclined plate；The both ends for connecing cash plate upwarp to form baffle, which welds together with inclined plate, and another is located at the outside of inclined plate, do not weld together with inclined plate.Draw the invention has the advantages that effectively buffering can be carried out between the spoil fallen in gap frame and connect, prevents to fall influence of the cash to personnel and equipment between frame, it is advantageous to ensure safety production environment；Baffle can effectively prevent dropping out for spoil, it is ensured that it falls in chute according to normal guiding planning.
Description
Technical field
The present invention relates to a kind of coal working face branch bridge joint cash devices.
Background technique
Underground coal mine coal working face is influenced often the presence of work by the more aspect such as geological conditions during back production
The phenomenon that making face roof cracking, reinforcing Safety Control of Roof in exploitation process is a very important major tasks, and in the world
What is not flawless, safe against all possibilities, often all there is some loopholes or deficiency, the protection of face roof is main
It is to be completed by bracket, the intact supporting of the top plate of working face is completed by multi-section bracket, and multi-section holder combination is complete at one
Complete top, bottom plate protection system, due to each portion's backing positions and itself design, all have between a bracket it is certain between
Gap varies, and inevitably has part spoil to stay between frame during bracket is operated during drawing shifting bracket or maintenance
When falling in some gaps before bracket foot pedal and in electric cable for coal mining machine slot, product cash increases influence blocking bracket push-pull rod and electricity
Cable slot causes bracket and draws the loss for moving difficult and electric cable for coal mining machine, cable clip, at the same safe construction to working face personnel and
Personnel's walking brings biggish security risk.
It, can not be according to scene since the side guard plate and top beam of the design reasons bracket of bracket only have certain protective range
Situation makes effective protection, the protective device that this problem of also doing nothing on the market at present specially designs.
Summary of the invention
To overcome the shortcomings of existing technologies, the present invention provides a kind of coal working face branch bridge joint cash device, skill of the invention
Art scheme is:
Coal working face branch bridge joint cash device, including mounting bracket and cash plate is connect, the top of the mounting bracket is provided with mounting hole,
Inclined plate is formed after bottom fold, the inclined plate and horizontal direction form angle, and the cash plate that connects is welded on inclined plate, flat with inclined plate
Row setting；The both ends for connecing cash plate upwarp to form baffle, which welds together with inclined plate, another position
In the outside of inclined plate, do not weld together with inclined plate.
The angle is 30 °.
Draw the invention has the advantages that effectively buffering can be carried out between the spoil fallen in gap frame and connect, prevents to fall cash between frame
Influence to personnel and equipment, it is advantageous to ensure safety production environment；Baffle can effectively prevent dropping out for spoil, it is ensured that it is pressed
It is fallen in chute according to normal guiding planning.
Detailed description of the invention
Fig. 1 is agent structure schematic diagram of the invention.
Fig. 2 is the A-A cross-sectional view of Fig. 1.
Specific embodiment
The invention will now be further described with reference to specific embodiments, the advantages and features of the present invention will be with description and
It is apparent.But examples are merely exemplary for these, and it is not intended to limit the scope of the present invention in any way.Those skilled in the art
Member it should be understood that without departing from the spirit and scope of the invention can details to technical solution of the present invention and form into
Row modifications or substitutions, but these modifications and replacement are fallen within the protection scope of the present invention.
Referring to Fig. 1 and Fig. 2, the present invention relates to a kind of coal working face branch bridge joint cash device, including mounting bracket 1 and cash is connect
Plate 2, the top of the mounting bracket 1 are provided with mounting hole, and inclined plate 3 is formed after bottom fold, and the inclined plate 3 and horizontal direction, which are formed, presss from both sides
Angle, the cash plate 2 that connects are welded on inclined plate 3, are arranged in parallel with inclined plate 3；The both ends for connecing cash plate upwarp to form baffle 4,
The a part for connecing cash plate 2 welds together with inclined plate 3, and another is located at the outside of inclined plate, does not weld together with inclined plate 3.
The angle is 30 °.
The working principle of the invention is: connecing cash form is that the slope 30o buffers guiding type and connects cash and fall cash, and it is effectively slow to will fall off spoil
Punching is directed in chute.Prevent spoil between frame fall at bracket foot pedal and electric cable for coal mining machine slot in influence pedestrian, bracket foot-operated
Normal draw of plate foreset cash obstruction bracket moves work and influences normally dragging for electric cable for coal mining machine, and the damage of spoil extrusion abrasion is mined
The phenomenon that electric cable.
