Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fully mechanized mining equipment, and in particular to a pushing structure, a transfer machine tail and a transfer machine. BACKGROUND

[0002] At a fully mechanized mining face in a coal mine, a transfer machine is installed in a transport roadway at a lower outlet of the working face, and is a crossheading conveying and transfer equipment used in conjunction with fully mechanized working face equipment. When the transfer machine is working, the tail end of the transfer machine is overlapped with a scraper conveyor, and the head end of the transfer machine is connected to the tail end of a belt conveyor, so that the transfer machine conveys and transfers coal from the scraper conveyor to the belt conveyor. During the process of advancing the fully mechanized working face forward, the transfer machine must move forward simultaneously with the fully mechanized working face.

[0003] During the process of mining and advancing the working face forward, the synchronous movement of the transfer machine is often realized by a striding self-moving device matched with the transfer machine.

[0049] In order to better explain the present application, so as to be understood, the present application is described in detail by specific embodiments, combined with the drawings.

[0050] In a fully mechanized coal mining face in a coal mine, a rehandler is installed in a mine working face lower outlet transportation roadway, and is a crossheading conveying and rehandling equipment used in conjunction with fully mechanized working face equipment. When the rehandler is working, the tail end of the rehandler is overlapped with a scraper conveyor, and the head end of the rehandler is connected with the tail end of a belt conveyor, so that the rehandler conveys and transfers the coal sent by the scraper conveyor to the belt conveyor. In the process of advancing the fully mechanized working face, the rehandler must move forward at the same time with the fully mechanized working face.

[0051] At present, the prior art is to realize synchronous movement through a step self-moving device matched with the transfer machine. The step self-moving device comprises a lifting device, a pushing cylinder and a mounting seat, and is coupled with the landing section of the transfer machine through the mounting seat to realize forward step self-moving of the transfer machine. If the floor condition of the roadway is good, the transfer machine can realize smooth movement; if the floor condition is poor, such as floor heave and high water content, the transfer machine is often stuck and recessed, which causes difficulty in forward movement of the transfer machine. Therefore, in this case, the roadway needs to be handled by manual labor, which increases the labor intensity of workers.

[0052] To solve the above problems, the prior art proposes a transfer machine tail linkage, which comprises a tail frame, a tail connecting seat, a linkage floor and a linkage ear plate. In the case of poor floor condition of the roadway, the existing support can be matched to realize forward movement of the transfer machine in the roadway. However, during mining and forward advancing of the working face, the working face and the roadway cannot be guaranteed to be flat, which causes transverse movement of the coupling and pushing position of the transfer machine tail. The linkage ear plate in the prior art tail is fixedly installed on the linkage floor and cannot realize transverse position adjustment. The pushing force direction is at an angle with the symmetry center plane of the tail, which causes pushing deviation, and the linkage ear plate is easily damaged by transverse pushing torque.

[0053] To solve at least one of the problems in the prior art or related art, the inventors consider that a plurality of first through holes are arranged on the pushing beam in the length direction of the pushing beam, a second through hole is arranged on the pushing seat, and the first detachable connecting part is connected with the second through hole and the plurality of first through holes to detachably fix the pushing seat on the target position of the pushing beam, so as to realize adjustment of the connection position of the pushing seat on the pushing beam, and the pushing force direction of the pushing device on the pushing seat is parallel to the central axis of the tail during pushing of the pushing device, so as to ensure smooth movement of the transfer machine.

[0054] The pushing structure, the transfer machine tail and the transfer machine according to some embodiments of the present application are described below with reference to the accompanying drawings.

[0055] Referring to Figure 1 and Figure 2The application provides a pushing structure of one embodiment, which is applied to a transfer machine and comprises a pushing beam 1, a pushing seat 2 and a first detachable connecting part 3, the pushing beam 1 is used for being connected with a tail frame body 4 of the transfer machine, a plurality of first through holes 101 are formed in the pushing beam 1 and are arranged along the length direction of the pushing beam 1, the pushing seat 2 is used for being connected with a pushing device, and the pushing seat 2 is provided with a second through hole 201, and the first detachable connecting part 3 is used for being connected with the second through hole 201 and the plurality of first through holes 101, so as to detachably fix the pushing seat 2 on a target position of the pushing beam 1, and after the pushing seat 2 is fixed on the target position, the pushing force direction of the pushing device to the transfer machine is parallel to the central axis of the tail frame of the transfer machine.

[0056] In the process of mining and advancing the working face, when the connecting and pushing position of the tail frame of the transfer machine needs to be adjusted laterally, the pushing seat 2 is fixed on the target position of the pushing beam 1 and the first through hole 101 on the target position, so that the pushing seat 2 is fixed on the target position through the first detachable connecting part 3 and the cooperation of the second through hole 201 and the first through hole 101 corresponding to the target position. Here, the target position is that the pushing force direction of the pushing device to the transfer machine is parallel to the central axis of the tail frame after the pushing seat 2 is fixed on the position, so that the deviation of the pushing of the transfer machine can be avoided when the pushing seat 2 is detachably fixed on the target position of the pushing beam 1, and the problem of stress damage of the pushing seat 2 caused by the lateral pushing torque can also be avoided. The target position in the embodiment is determined according to the pushing force direction of the pushing device to the transfer machine.

[0057] It should be noted that the pushing device here can be a step self-moving device, which can be a end support or a gangue support. By connecting the step self-moving device with the pushing structure in the embodiment, the transfer machine can be smoothly moved forward in the roadway.

[0063] Here, the distance between the corresponding connection positions of the two first connecting plates 203 and the fourth connecting plate 2022 is close to the thickness of the push beam 1, so that when the push beam 1 is located between the two first connecting plates 203, the two opposite surfaces of the two first connecting plates 203 are respectively in contact with the upper surface and the lower surface of the push beam 1.

[0064] In this embodiment, by hinging the two opposite and parallel first connecting plates 203 to the push seat 2 respectively, the opening size between the two first connecting plates 203 can be controlled, so as to place the push seat 2 on the target position of the push beam 1, and then cooperate the first detachable connecting part 3 with the second through hole 201 and the first through hole 101 at the target position, so as to detachably fix the push seat 2 on the target position of the push beam 1.
