Abstract
The invention relates to a shield support of a coal cutter. The shield support comprises a base and is characterized in that the base is fixedly connected with a stand column and a movable base, the stand column and the movable base are fixedly connected with a shield beam together, and the shield beam is fixedly connected with a short beam through a short column. The shield support is simple in structure, overcomes the defects that a traditional hydraulic support is large in size and poor in supporting performance, has good protective performance and greatly improves supporting force, and the usage range is enlarged.
Description
Technical field:
The present invention relates to coal mining equipment, particularly the hydraulic prop device of coal-winning machine.
Background technology:
Hydraulic support is a kind ofly to support and manage top board and safeguard the hydraulic power unit of 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, transport 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, also can prevent to a certain extent that erecting dense individual props rock from entering Kong Ding 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, for the above-mentioned shortcoming of conventional hydraulic support, studies and improves, and a kind of hydraulic chock of coal-winning machine is provided, and it has simple in structure, convenient disassembly, and little feature takes up room.
In order to address the above problem, the present invention adopts following scheme:
A shield for 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 invention is:
The present invention 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 expanded the scope of application.
Brief description of the drawings:
Fig. 1 is main TV structure schematic diagram of the present invention.
Detailed description of the invention:
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
See Fig. 1, the present invention includes base 1, 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 present invention 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 expanded the scope of application.
