Embodiment 1

[0035] This embodiment provides a chain tension adjustment device for the tail of a scraper machine, including a body 16, a telescopic mechanism arranged on the body 16, a bearing seat 17, a connecting rod and a locking mechanism, wherein the telescopic mechanism, the bearing seat 17. The connecting rods are connected in turn, and the telescopic mechanism drives the bearing seat to move through its own expansion and contraction to adjust the tension of the chain, and automatically locks or loosens the connecting rod on one side of the bearing seat 17 through the locking mechanism. In the present invention, the bearing seat 17 is connected with the sprocket shaft of the tail of the scraper machine, and the movement of the sprocket shaft is driven by the movement of the bearing seat, so as to adjust the position of the chain on the sprocket shaft, thereby achieving the chain tension (loose chain or tight chain) ) for the purpose of regulation.

Embodiment 2

[0045] This embodiment provides a chain tension adjustment device for the tail of the scraper machine, the structure is as described in Embodiment 1, the difference is that a torque limiter 3 is also connected between the reducer 2 and the gear shaft 6 , The torque limiter can effectively prevent the lock nut from over-tightening the lead screw.

[0046] Simultaneously, a support base 10 is installed between the reducer 2 and the torque limiter 3, a bearing support 5 is installed between the gear shaft 6 and the torque limiter 3, a bearing is installed on the top of the bearing support 5, and the gear shaft 6 One end of the shaft passes through the bearing and is connected with the torque limiter 3, and the bearing support 5 is provided with a travel switch 12. The travel switch 12 can be used to realize the distance control between the lock nut 7 and the bearing support 5 .

Embodiment 3

[0048] A method for using the chain tension adjustment device for the tail of the scraper machine as described in Embodiment 2, the specific steps are as follows:

[0049] Such as Figure 7 As shown, when it is necessary to tighten the chain of the scraper machine, the hydraulic cylinder 18 drives the piston rod to stretch out and push the bearing seat 17 to move. During the movement of the bearing seat 17, it drives the lead screw 15 to move. During the movement, the displacement sensor 4 can detect The distance that the leading screw moves (that is, the distance that the piston rod protrudes), when the displacement sensor 4 detects that the leading screw moves to the set distance and the oil pressure in the hydraulic cylinder 18 reaches a specified value, the drive to the hydraulic cylinder 18 is stopped; When the servo motor 1 starts, the reducer 2, the torque limiter 3, and the gear shaft 6 rotate in turn to drive the lock nut 7 to rotate, and the rotation of the lock nut ...

Abstract

The invention relates to a chain tension regulating device used for the tail of a scraper and application thereof. The chain tension regulating device used for the tail of the scraper comprises a body as well as a telescopic mechanism, a bearing block, a connecting rod and a locking mechanism which are arranged on the body, wherein the telescopic mechanism, the bearing block and the connecting rod are sequentially connected, the telescopic mechanism drives the bearing block to move to regulate tension of a chain, and the connecting rod at one side of the bearing block is automatically locked or loosened by virtue of the locking mechanism. The chain tension regulating device provided by the invention has the advantages that the bearing block is connected with a sprocket shaft at the tail of the scraper, and the bearing block moves to drive the sprocket shaft to move, so as to regulate tightness of the chain on the sprocket shaft, so that the aim of regulating the tension of the chain (loosening or tightening the chain) is achieved, moderate tightness degree of a scraper chain during operation is guaranteed, and a technical guarantee is provided for safe operation of the scraper; and the chain tension regulating device is smart in design and high in automation degree, a regulating process is accurate and controllable, and the chain tension regulating device is easy to mount and obvious in effect.

Description

technical field [0001] The invention relates to a chain tension adjusting device for the tail of a scraper machine and its application, belonging to the technical field of scraper machines. Background technique [0002] As the main transportation equipment of fully mechanized mining face, the scraper conveyor is developing in the direction of large capacity, long distance and high power. The scraper chain is one of the important components of the scraper conveyor. As the traction mechanism of the scraper conveyor, the scraper chain restricts the normal operation of the scraper conveyor, and at the same time affects the safety and production of the mine. In order to ensure that the scraper chain adapts to the change of load and make the chain work in a moderately elastic state, it is necessary to adjust and precisely control the chain tension of the scraper conveyor in real time. [0003] For example, Chinese patent document CN203516621U discloses a scraper chain automatic t...
