Abstract
The utility model 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.The utility model has the advantages that: effectively the spoil fallen in gap frame can be carried out buffering to connect drawing, prevent 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 utility model 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.
Utility model content
To overcome the shortcomings of existing technologies, the utility model provides a kind of coal working face branch bridge joint cash device, this is practical
Novel technical solution 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 peace
Hole is filled, forms inclined plate after bottom fold, the inclined plate and horizontal direction form angle, and the cash plate that connects is welded on inclined plate, with
Inclined plate is arranged in parallel；The both ends for connecing cash plate upwarp to form baffle, which welds together with inclined plate, separately
One is located at the outside of inclined plate, does not weld together with inclined plate.
The angle is 30 °.
The utility model has the advantages that: buffering effectively can be carried out between the spoil fallen in gap frame and connect and draw, prevented between frame
Influence of the cash to personnel and equipment is fallen, 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.
Detailed description of the invention
Fig. 1 is the agent structure schematic diagram of the utility model.
Fig. 2 is the A-A cross-sectional view of Fig. 1.
Specific embodiment
Further describe the utility model combined with specific embodiments below, the advantages of the utility model and feature will be with
Description and it is apparent.But examples are merely exemplary for these, does not constitute any restrictions to the scope of the utility model.
It will be understood by those skilled in the art that can be to the utility model skill under the spirit and scope without departing from the utility model
The details and form of art scheme are modified or are replaced, but these modifications and replacement each fall within the protection scope of the utility model
It is interior.
Referring to Fig. 1 and Fig. 2, the utility model relates to a kind of coal working face branch bridge joint cash devices, including 1 He of mounting bracket
Cash plate 2 is connect, the top of the mounting bracket 1 is provided with mounting hole, forms inclined plate 3, the inclined plate 3 and horizontal direction shape after bottom fold
At angle, the cash plate 2 that connects is welded on inclined plate 3, is arranged in parallel with inclined plate 3；The both ends for connecing cash plate upwarp to form gear
Plate 4, a part for connecing cash plate 2 weld together with inclined plate 3, and another is located at the outside of inclined plate, are not welded on one with inclined plate 3
It rises.The angle is 30 °.
Cash is fallen the working principle of the utility model is: connecing cash form and connecing cash for the slope 30o buffering guiding type, will fall off spoil has
Effect buffering 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
The normal of foot pedal foreset cash obstruction bracket draws shifting work and influences normally dragging for electric cable for coal mining machine, the damage of spoil extrusion abrasion
The phenomenon that electric cable for coal mining machine.
