Description

Technical Field

[0001] This utility model belongs to the field of coal fully mechanized mining support technology, specifically relating to a motor pulling auxiliary device for fully mechanized mining faces. Background Technology

[0002] my country has abundant coal reserves and is a major coal producer. In fully mechanized coal mining equipment, during the mining of longwall faces, it is necessary to ensure that the scraper conveyor remains on the same horizontal line after the pusher and puller are completed. In recent years, with the development of fully mechanized mining technology, the centrally positioned end support has been used in more and more longwall faces. Compared with traditional end supports, the centrally positioned end support has advantages such as better support performance and stronger adaptability. When the longwall face uses the centrally positioned end support, the motor at the face head will not be aligned with the face when it moves forward because there is no push point at the rear. This poses a significant safety hazard over a long period of mining, and in severe cases, may cause underground safety accidents. Utility Model Content

[0003] This utility model overcomes the shortcomings of the prior art and proposes an auxiliary device for pulling a motor in a fully mechanized mining face; it solves the problem that the motor at the head of the fully mechanized mining face cannot keep flush with the working face when moving.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution.

[0005] An auxiliary device for driving a motor in a fully mechanized mining face is installed between a centrally located end support and a transfer machine. It includes a connecting seat, an auxiliary jack, and a circular chain. The transfer machine is installed inside the base of the centrally located end support. A connecting seat is located on each of the left and right sides of the front end of the transfer machine. A pushing jack is installed on the rear side of each connecting seat and connected to the support base. A connecting trunnion is fixedly installed on the right side of the right connecting seat, and an auxiliary jack is installed on the connecting trunnion. The auxiliary jack is connected to the fully mechanized mining face motor via the circular chain.

[0006] Furthermore, the front end of the transfer machine extends to the outer side of the front end of the support base.

[0007] Furthermore, one end of the cylinder bottom of the push jack is hinged to the rear end of the connecting seat, and one end of the piston rod of the push jack is hinged to the front end of the support base on the same side through the push connector.

[0008] Furthermore, the connecting trunnion is horizontally positioned along the left-right direction, and the left end of the connecting trunnion is fixedly connected to the right side of the connecting seat on the right side.

[0009] Furthermore, the auxiliary jack is hinged to the right end of the connecting trunnion. One end of the cylinder bottom of the auxiliary jack is hinged to the right end of the connecting trunnion, and one end of the piston rod of the auxiliary jack extends backward.

[0010] Furthermore, the motor of the fully mechanized mining face is located behind the auxiliary jack. A first auxiliary connector is provided at one end of the piston rod of the auxiliary jack, and a second auxiliary connector is provided at the front end of the motor of the fully mechanized mining face. The aforementioned circular chain is provided between the first auxiliary connector and the second auxiliary connector.

[0011] The beneficial effects of this utility model compared to the prior art are as follows:

[0012] This utility model provides a motor-driven auxiliary device for fully mechanized mining faces.

Detailed Implementation

[0018] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, this utility model will be further described in detail with reference to the embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit it. The technical solution of this utility model will be described in detail below with reference to the embodiments and accompanying drawings, but the scope of protection is not limited thereto.

[0019] like Figure 1 As shown in Figure 3, this utility model provides a motor pulling auxiliary device for a fully mechanized mining face, which is set between the centrally located end support 1 and the transfer machine 7, and includes a connecting seat 8, an auxiliary jack 10, and a circular chain 12.

[0020] A transfer mechanism 7 is installed inside the support base 2 of the centrally located end bracket 1. The front end of the transfer mechanism 7 extends to the outer side of the front end of the support base 2. A connecting seat 8 is installed on the left and right sides of the front end of the transfer mechanism 7. The transfer mechanism 7 and the connecting seat 8 are connected by three pins: front, middle, and rear. A push jack 3 is installed on the rear side of each connecting seat 8. One end of the cylinder bottom of the push jack 3 is hinged to the rear end of the connecting seat 8, and one end of the piston rod of the push jack 3 is hinged to the front end of the support base 2 on the same side through a push connector 4.

[0021] A connecting trunnion 9 is fixedly installed on the right side of the connecting seat 8. The connecting trunnion 9 is horizontally arranged in the left-right direction, and its left end is fixedly connected to the right side of the connecting seat 8. An auxiliary jack 10 is hinged to the right end of the connecting trunnion 9. One end of the cylinder bottom of the auxiliary jack 10 is hinged to the right end of the connecting trunnion 9, and one end of the piston rod of the auxiliary jack 10 extends backward.

[0022] A fully mechanized mining face motor 6 is installed on the rear side of the auxiliary jack 10. A first auxiliary connector 11 is installed at one end of the piston rod of the auxiliary jack 10. A second auxiliary connector 13 is installed at the front end of the fully mechanized mining face motor 6. A circular chain 12 is installed between the first auxiliary connector 11 and the second auxiliary connector 13.

[0023] When it is necessary to install the motor 6 of the fully mechanized mining face, the layout of the underground working face is first understood and analyzed. After calculation, the external dimensions of the motor pulling auxiliary device 5, the stroke of the auxiliary jack 10, the length of the circular chain 12, etc. are obtained to meet the production requirements of the working face layout. Then, the installation position of the pulling device is reserved at the transfer machine 7 and the fully mechanized mining face motor 6.

[0024] First, the connecting seat 8 is connected to the transfer machine 7 via a pin connection. Then, the connecting trunnion 9 is connected to the connecting seat 8 via a stop pin connection. Next, the connecting trunnion 9 is connected to one end of the cylinder bottom of the auxiliary jack 10 via a pin connection. One end of the piston rod of the auxiliary jack 10 is also connected to the first auxiliary connecting head 11 via a pin connection. The first auxiliary connecting head 11 is connected to one end of the circular chain 12 via a pin connection. The other end of the circular chain 12 is connected to the second auxiliary connecting head 13. The second auxiliary connecting head 13 is connected to the fully mechanized mining face motor 6 via a pin connection. The assembly is simple and quick, and the use is flexible and convenient, which can adapt to the needs of different mines.

[0025] The motor-pulling auxiliary device 5 can flexibly and effectively adjust the position of the fully mechanized mining face motor 6. When the working face moves forward, the central end support 1 moves forward with the transfer machine 7. At this time, the motor-pulling auxiliary device 5 will move forward together. At this time, the fully mechanized mining face motor 6 will lag behind the working face. By operating the auxiliary jack 10 to pull the fully mechanized mining face motor 6, the levelness of the fully mechanized mining face can be ensured.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
