The utility model can realize single welding, thereby saving labor cost, ensuring the safety in the construction process, improving the work efficiency of maintenance and saving production cost.
Description
Technical Field
The utility model relates to the field of maintenance tools for coal mining machines, in particular to a maintenance supporting tool for a drum of a coal mining machine.
Background
The roller is an important part of the coal mining machine, and the roller needs to be frequently turned to adjust the optimal repairing direction to meet the repairing process requirement when being repaired due to the complex external structural form of the roller of the coal mining machine, so that a plurality of people are required to cooperate with a travelling crane to turn the roller. Not only a large amount of time is consumed in the overturning process, but also the safety in the overturning process cannot be guaranteed due to the fact that the roller of the coal mining machine is heavy.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a maintenance supporting tool for a coal mining machine roller, which solves the problem of inconvenient overturning of the coal mining machine roller in the prior art due to the fact that a travelling crane is adopted for overturning during maintenance.
In order to achieve the purpose, the technical scheme adopted by the utility model is as follows:
the utility model provides a coal-winning machine cylinder maintenance support frock, includes chassis and backup pad, and backup pad one side is rotated and is connected in chassis one side, and is connected through the jack between chassis and the backup pad, rotates in the backup pad and installs the carousel, is fixed with the positioning seat on the carousel.
Furthermore, articulated arms are respectively hinged to one end of each of two sides of the chassis in the same direction, and the bottom of one side of the support plate is fixed to the two articulated arms, so that the support plate is rotatably connected to the chassis.
Furthermore, the cylinder body end of the jack is hinged to the chassis, and the top rod end of the jack is obliquely and upwards hinged to the bottom of the supporting plate.
Furthermore, the shape of the positioning seat is matched with the shape of the interior of a drum of the coal mining machine.
The utility model relates to a maintenance support tool for a drum of a coal mining machine, which is characterized in that a base part consisting of a chassis and a support plate is designed, one side of the support plate in the base part is rotatably connected to one side of the chassis in a hinged mode, a jack is hinged to the chassis, the top rod end of the jack is obliquely and upwards hinged to the bottom of the support plate, a turntable is rotatably installed at the top of the support plate, and a positioning seat matched with the shape of the interior of the drum of the coal mining machine is fixed on the turntable.
Therefore, the drum of the coal mining machine can be sleeved in the positioning seat through the drum when being maintained, then the supporting plate is jacked to a proper maintenance angle through the jack, and the drum can be directly rotated in the maintenance process.
Compared with the prior art, the utility model has the advantages that:
1) the utility model can realize single-person welding without the cooperation of a plurality of persons for rotating the roller, thereby saving the labor cost. The electric welder adjusts the angle of the roller by operating the jack, and can rotate the roller by oneself to realize the multi-azimuth and multi-angle adjustment of the roller, and the operation is simple and convenient.
2) The utility model can ensure the safety in the construction process, increase the safety coefficient of the construction process and reduce the labor intensity of workers.
3) After the utility model is used, the maintenance air supply of the roller of the coal mining machine can be effectively shortened, the construction period is shortened by five days, and therefore, the maintenance work efficiency can be improved, and the production cost can be saved.
