Abstract
The utility model relates to a shield support of a coal mining machine. The shield support comprises a base, and is characterized in that the base is fixedly connected with vertical columns and movable bases, the vertical columns and the movable bases are jointly fixedly connected with a shield beam, and the shield beam is fixedly connected with a top beam by the aid of a short column. The shield support is simple in structure, overcomes the shortcomings of large size and poor supporting performance of a traditional hydraulic support, and has a fine protective performance. Supporting force is greatly increased, and the usable range is widened.
Description
Technical field:
The utility model relates to coal mining equipment, particularly the hydraulic prop device of coal-winning machine.
Background technology:
Hydraulic support is a kind of hydraulic power unit that supports and manage top board and safeguard necessary working space, its advantage not only shows very high enabling capabilities, make roof control more reliable, and can realize automatic passing, make coal mining, transportation and supporting operation simultaneously, form continuous manufacturing process, it is the requisite corollary equipment of comprehensive mechanical coal mining.The effect of hydraulic chock-shield support is mainly to support and controlroof, can prevent to a certain extent that also the erecting dense individual props rock from entering control top district, and it has the top of cutting effect, and with the passing of support, the balkstone that its candidate exposes can all be caving.Its structure of traditional hydraulic support is too complicated, and it is large to take up room, and supporting is not good, is unfavorable for installation and removal.
Summary of the invention:
The applicant studies and improves for the above-mentioned shortcoming of conventional hydraulic support, and a kind of hydraulic chock of coal-winning machine is provided, and it has simple in structure, convenient disassembly, and little characteristics take up room.
In order to address the above problem, the utility model adopts following scheme:
A kind of shield of coal-winning machine comprises base, it is characterized in that: described base is fixedly connected with column and false bottom seat, and described column and false bottom seat are fixedly connected with caving shield jointly, and described caving shield is fixedly connected with back timber by short column.
Further technical scheme is:
Described false bottom seat is connected with caving shield by connecting rod; The end of described back timber connects baffle plate, and described baffle plate is fixedly connected with described caving shield.
Technique effect of the present utility model is:
The utility model is simple in structure, has overcome that conventional hydraulic support volume is large, the poor shortcoming of supporting, has good barrier propterty, has greatly improved support force, has enlarged the scope of application.
Description of drawings:
Fig. 1 is main TV structure schematic diagram of the present utility model.
The specific embodiment:
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further.
See Fig. 1, the utility model comprises base 1, and base 1 is fixedly connected with column 2 and false bottom seat 8, and column 2 and false bottom seat 8 are fixedly connected with caving shield 6 jointly, and caving shield 6 is fixedly connected with back timber 3 by short column 4.False bottom seat 8 is connected with caving shield 6 by connecting rod 7; The end of back timber 3 connects baffle plate 5, and baffle plate 5 is fixedly connected with caving shield 6.
The utility model is simple in structure, has overcome that conventional hydraulic support volume is large, the poor shortcoming of supporting, has good barrier propterty, has greatly improved support force, has enlarged the scope of application.
