Problems solved by technology

[0002] The lifting and self-locking device of mining machinery is used to realize the lifting support in the mining process of mine resources. The technical structure has the effect of improving safety and detection and control operation. However, the existing lifting device has poor self-locking effect and poor protection effect. Structural failure will cause the lifting plate to drop suddenly, causing the machine to fall and be damaged, and then a mining machine lifting self-locking device is proposed

Embodiment

[0022] Embodiment: by starting the driving motor 13, the driving motor 13 works to drive the second two-way screw mandrel 28 to rotate, and the rotating second two-way screw mandrel 28 can drive the first two-way screw mandrel 5 to rotate through the shaft coupling 11, and the rotating first two-way screw mandrel 28 can rotate. The screw mandrel 5 and the second two-way screw mandrel 28 can drive two nut blocks 6 on its upper end to move towards or back to each other. At this moment, the nut block 6 drives the guide slide block 9 to slide in the guide chute 10 through the guide rod 7, and then can Drive the support plate 1 to move up and down through the first hinged rod 4 and the second hinged rod 18 to realize the adjustment of the height of the support plate 1. After the adjustment is completed, the drive motor 13 is turned off, and the first two-way screw rod 5 and the second two-way screw are stopped. The driving force of the rod 28 can further realize the locking of the s...

Abstract

The invention belongs to the field of mining machinery, and discloses a mining machinery lifting self-locking device. The device comprises a base, wherein a mounting groove is arranged in the upper end of the base; a driving motor is fixedly arranged at the left end of the base; an output shaft of the driving motor is fixedly connected to a second two-way lead screw; the output shaft of the driving motor penetrates through the base and is fixedly connected to the second two-way lead screw; the right end of the second two-way lead screw is fixedly connected to a first two-way lead screw througha coupler; the right end of the first two-way lead screw is rotationally connected to the base through a bearing; the first two-way lead screw and the second two-way lead screw are both located in the mounting groove; and two nut blocks are symmetrically arranged on the first two-way lead screw and the second two-way lead screw in a threaded mode. The device is good in lifting adjusting effect, good in self-locking effect, good in protection effect, high in safety and high in practicability.

Description

technical field [0001] The invention relates to the technical field of mining machinery, in particular to a lifting self-locking device for mining machinery. Background technique [0002] The lifting and self-locking device of mining machinery is used to realize the lifting support in the mining process of mine resources. The technical structure has the effect of improving safety and detection and control operation. However, the existing lifting device has poor self-locking effect and poor protection effect. Structural failures will cause the lifting plate to drop suddenly, causing the machine to fall and be destroyed. A lifting self-locking device for mining machinery is proposed. Contents of the invention [0003] A lifting self-locking device for mining machinery proposed by the invention solves the problems in the background technology. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A lifting se...
