Description

Tool for replacing crusher of coal mining machine

Technical Field

The utility model relates to a combine and adopt working face coal mining field, concretely relates to change coal-winning machine breaker instrument.

Background

The coal mining machine is one of key devices for fully mechanized coal mining face production. In the underground mining of thick coal seams, due to the rib spalling of the coal wall, large coal often falls on the scraper conveyor, so that in order to avoid the large coal from forcing the traveling speed of the coal mining machine to be reduced, and even stop the machine, a crusher is arranged at one end of the coal mining machine close to the air return tunnel to crush the large coal. The torque shaft of the crusher is easy to break due to overload and other reasons in the production process. The torque shaft is connected with a crusher A gear and a crusher motor through two groups of splines respectively, and the end part of the torque shaft is protected by an end cover, so that the clamp spring is prevented from breaking down and damaging equipment. When the moment of torsion axle breaks, because the end cover installation is fastened, dismantle and slowly dismantle the end cover with the jackscrew at every turn, it is wasted time and energy to change new moment of torsion axle, seriously influences production.

Disclosure of Invention

An object of the utility model is to provide a change coal-winning machine breaker instrument has solved the above-mentioned not enough that exists among the prior art.

In order to achieve the above purpose, the utility model discloses a technical scheme is:

the utility model provides a tool for replacing a crusher of a coal mining machine, which comprises a main shaft and a hammer head, wherein the hammer head is sleeved on the main shaft; when the hammer is used, one end of the main shaft is installed in the torque shaft installation hole in a matching mode, and the hammer head is arranged on the outer side in the torque shaft installation hole.

Preferably, the main shaft is threadedly connected with the torque shaft mounting hole.

Preferably, a bolt is welded at one end of the main shaft, and the bolt is in threaded connection with the torque shaft mounting hole when in use.

Preferably, a handle is welded to one end of the main shaft.

Preferably, the hammer comprises a main shaft and a hammer head, wherein the hammer head is sleeved on the main shaft; a bolt is welded at one end of the main shaft and is in threaded connection with the torque shaft mounting hole when in use; the hammer is arranged on the outer side in the torque shaft mounting hole.

Preferably, the hammer comprises a main shaft and a hammer head, wherein the hammer head is sleeved on the main shaft; a handle is welded at one end of the main shaft, a bolt is welded at the other end of the main shaft, and the bolt is in threaded connection with the torque shaft mounting hole when in use; the hammer is arranged on the outer side in the torque shaft mounting hole.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model provides a pair of change coal-winning machine breaker instrument through the swing tup, demolishs the moment of torsion axle end cover, later demolishs disconnected moment of torsion axle that falls, and this structure has realized the quick replacement of moment of torsion axle, has solved and has changed slowly in the present production, consumes the many problems of worker.

Drawings

Fig. 1 is a schematic structural diagram according to the present invention.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1, the utility model provides a tool for replacing a crusher of a coal mining machine, which comprises a main shaft 1 and a hammer head 2, wherein the hammer head 2 is sleeved on the main shaft 1; when the hammer is used, one end of the main shaft 1 is installed in the torque shaft installation hole in a matching mode, and the hammer head 2 is arranged on the outer side in the torque shaft installation hole; through swing tup 2, demolish the moment of torsion axle end cover of installation in the moment of torsion axle mounting hole, later demolish disconnected moment of torsion axle, this structure has realized the quick replacement of moment of torsion axle, has solved and has changed slowly in present production, consumes the problem that the worker is many.

Further, the utility model provides a change coal-winning machine breaker instrument, including main shaft 1 and tup 2, tup 2 suit is on main shaft 1; when the positioning device is used, one end of the main shaft 1 is installed in the torque shaft installation hole in a threaded mode, the hammer head 2 is arranged on the outer side in the torque shaft installation hole, the main shaft 1 is positioned, and the phenomenon that the end cover is detached due to eccentricity is prevented from occurring.

Further, the utility model provides a change coal-winning machine breaker instrument, including main shaft 1 and tup 2, tup 2 suit is on main shaft 1; a bolt 4 is welded at one end of the main shaft 1, the bolt 4 is in threaded connection with a torque shaft mounting hole when in use, and the hammer head 2 is arranged on the outer side in the torque shaft mounting hole; the production time of torque shaft breakage influence in the production process is reduced, the labor intensity of workers during accessory replacement is reduced, potential safety hazards are reduced, and the working efficiency is improved.

Examples

The utility model provides a tool for replacing a crusher of a coal mining machine, which comprises a main shaft 1 and a hammer head 2, wherein the hammer head 2 is sleeved on the main shaft 1; a handle 3 is installed at one end of the main shaft 1, and a bolt 4 is arranged at the other end of the main shaft.

The main shaft is round steel with the diameter of phi 30x300 mm; the hammer head 2 is a cylindrical pin with the diameter of 100x200mm, and a through hole is formed in the center of the cylindrical pin; the bolt is an M10 bolt.

The utility model discloses a working process:

1. firstly, removing a snap spring and a plug on an end cover by using a spanner;

2. screwing the bolt 4, swinging the hammer head 2 on the tool for several times, and removing the end cover;
