Abstract
The utility model relates to a coal mining machine cable holding frame, and in particular relates to a quick insertion type coal mining machine cable holding frame fixing structure, aiming at solving the problems of infirmness in fixing between the conventional cable holding frame and a coal mining machine body and easiness in efficacy loss are solved. The quick insertion type coal mining machine cable holding frame fixing structure comprises screws and gaskets which are used for fixedly connecting the coal mining machine body and a cable holding frame fixing plate; and positioning pins are arranged at a fixed joint of the coal mining machine body and the cable holding frame fixing plate. By the quick insertion type coal mining machine cable holding frame fixing structure, the coal mining machine body and the cable holding frame fixing plate can be firmly fixed and are convenient to mount and dismount.
Description
Technical field
The utility model relates to coal-winning machine holder cable frame, particularly a kind of push-in coal-winning machine holder cable frame fixed structure.
Background technology
When the towing cable frame mechanism is coal-winning machine work, along about work plane, drag cable clamp (cable and water pipe are contained in the cable clamp, and are subjected to the protection of cable clamp), the device at power supply and water source is provided for coal-winning machine.
The fixed structure of original holder cable frame is very simple, and twisted buckle forms screw thread on the coal-winning machine fuselage, processes through hole on the holder cable frame fixed head, will ask the cable frame to be fastened to fuselage by bolt, finishes the fixing of holder cable frame and coal-winning machine fuselage.
There is following problem in this structure:
(1) when mining face under mine is longer, the length that the cable water pipe that coal-winning machine pulls adds cable clamp more also increases, and makes the load that acts on the holder cable frame strengthen.Make fastening bolt lost efficacy by shearing force.
(2) because the material of coal-winning machine fuselage adopts ordinary low-carbon steel, the tensile strength of its performance is lower, directly the screw strength of twisted buckle formation is low on fuselage, so the binding thread of fixing holder cable frame is also often threaded off and was lost efficacy on the fuselage, and this problem when occurring coal-winning machine necessarily be in underground work, can not handle (any non-explosion-proof instrument must not be gone into the well) at all.
Summary of the invention
The utility model is fixing insecure in order to solve holder cable frame and coal-winning machine fuselage, the easy problem that lost efficacy, thus a kind of push-in coal-winning machine holder cable frame fixed structure is provided.
In order to address the above problem, the utility model is taked following technical scheme: a kind of push-in coal-winning machine holder cable frame fixed structure, comprise that be used to the screw and the packing ring that are connected and fixed coal-winning machine fuselage and holder cable frame fixed head, the place of being connected and fixed of coal-winning machine fuselage and holder cable frame fixed head is provided with alignment pin.
Position and the place, alignment pin axle center of coal-winning machine fuselage and the corresponding alignment pin of holder cable frame fixed head are provided with peep hole.
The corresponding position of coal-winning machine fuselage and screw is provided with T type groove, is provided with the T type nut supporting with screw in the T type groove.
The beneficial effects of the utility model are as follows:
1, in existing equipment, increases alignment pin, make holder cable frame and coal-winning machine fuselage realize accurately location, avoid fastening bolt to be subjected to shearing force;
2, increase peep hole, can know the situation of checking assembling by the peep hole workman during assembling, make when alignment pin and bolt are installed boring ratio to be easier to, convenient mounting or dismounting;
3, increase T type nut, solved the shortcoming that screw intensity is not high, replacing is difficult for that the direct twisted buckle of coal-winning machine fuselage forms, T type nut location is installed increases the T type groove structure, during installation T type nut is inserted T type groove and gets final product, reduced the trouble of spanner hold-down nut, made that assembling is convenient.
