Background technique

Known mining winches include column return winches, slow speed winches, dispatching winches, and transport winches. Although these winches can complete specific work requirements, each winch has problems of varying degrees; for example: short life, low traction Small, wide structure and other disadvantages. The patent number is 89218687.9, which discloses a "two-speed multi-purpose winch", and the patent numbers are 200610038522.6 and 200620069642.8, which also discloses "a mining winch for back column scheduling". These two winches overcome the problems of the above-mentioned winches, and It can be used for multiple purposes, and has achieved good results in the actual use of the site, bringing benefits to coal mines. It has been used in coal mines for many years. However, due to the complexity of coal seam occurrence conditions in China's coal mines, with the With the development of mechanization in small coal mines, the above two winches are large in size and complex in structure, and are difficult to adapt to the small working space of small and medium coal mines.

Contents of the invention

Technical problem: The purpose of this utility model is to provide a simple structure, small volume, and simple operation of a fool-type mining winch.

Technical solution: The mining column return winch of the utility model includes a motor on the base, a coupling with a brake wheel, a brake, a reducer and a reel device, wherein: the motor passes through the coupling with a brake wheel The reducer is connected with the reducer, the brake is set on the outer edge of the coupling brake wheel, the output end of the reducer is connected to the reel device, and the closed box of the reducer is a pair of bevel gears and three pairs of cylindrical gears meshing The four-stage gear transmission, wherein: the first-stage transmission is a bevel gear transmission composed of shaft gears and bevel gears; A cylindrical gear transmission composed of several bearings and keys; a first-stage cylindrical gear pair transmission composed of a small internal spline cylindrical gear, a bridge gear and bearings is arranged in the open box of the reducer.

The brake is an electro-hydraulic control brake or a manual brake.

Beneficial effects: Since the reducer of the column return winch used in this mine is a single-speed reducer, it is especially suitable for the column return of the coal mining face and the relocation of medium and large fully mechanized mining equipment under the condition of a particularly narrow working space in a coal mine. Compared with the prior art, the utility model has the advantages of compact structure, simple manufacturing process, low cost, flexible and convenient operation, good braking effect, safety and reliability, and wide practicability.

Detailed ways

An embodiment of the present utility model is further described below in conjunction with accompanying drawing:

As shown in the figure, the mining column return winch is mainly composed of a motor 1, a coupling with a brake wheel 2, an electro-hydraulic control brake 3, a reducer 4, a reel device 5 and a base 6. The base 6 is welded by section steel. In the length direction, the front and rear sides are each a long channel steel, and the two ends of the long channel steel are respectively provided with connecting plates to connect the two channel steels to form a frame structure; A steel plate is welded on the long channel steel, and several through holes are opened on the steel plate. The motor 1, the electro-hydraulic control brake 3, the reducer 4 and the reel device 5 are fixed together with the base 6 by bolt groups; Transmission to the reducer 4, and then to the reel device 5, through the bridge gear 16 in the open box of the reducer 4, the power is transmitted to the large gear ring of the reel device 5, thereby driving the reel to rotate; There are four short channel steels welded between the two channel steels on the side where the motor 1 and the electro-hydraulic control brake 3 are installed, and the distance between the two short channel steels is relatively large. The channel steels are welded with steel plates and have several through holes , is used to install the motor 1; the distance between the other two short channel steels is small, steel plates are welded on the channel steels, and there are also a number of through holes, which are used to install the electro-hydraulic control brake 3; There are ribs in the channel of the channel steel to strengthen the support.
