Description

A height-adjustable support for a mine conveyor belt

Technical Field

The invention relates to the technical field of equipment used in mining, in particular to a support for a mine conveyor belt with adjustable height.

Background technique

In the mining process, conveying equipment is needed to transport ore. After the ore is mined, the terrain is complex and extremely uneven. The conveying device is lifted and lowered by matching the threaded rod and the threaded sleeve.

However, the current receiving and sending device can only lift and lower both sides of one end of the conveying equipment at the same time. Once the ground is uneven, even if the lifting is completed, the conveying equipment is still in a tilted state, affecting the transportation of ore. After the height adjustment is completed, it will not be fixed, making the height of the conveying equipment easy to drop during operation.

For example, a height-adjustable support for a mine conveyor belt disclosed in Chinese patent CN217675139U is used. By turning the handle, the handle drives the square rod to rotate. The square rod cooperates with the square hole. The bottom of the support rod is connected to the base through a bearing to enable the support rod to rotate. The support rod cooperates with the threaded sleeve so that the threaded sleeve can move upward. The threaded sleeve drives the connecting block to move upward through the U-shaped fixing block. The connecting block drives the guide roller to move upward through the connecting plate. The height of the guide roller is adjusted, and one end of the conveying device is raised so that the conveying device can be adjusted in height as needed. In the device, the left and right threaded sleeves can move independently. Even if the ground is uneven, the guide roller can be adjusted to a horizontal level. At the same time, the square rod The circular fixed block is driven to rotate, and the triangular clamping block arranged on the outer wall of the circular fixed block is rotated. The long side of the triangular clamping block contacts the left side of the positioning block. The left side of the positioning block is set as an inclined surface matching the triangular clamping block. The triangular clamping block will push the positioning block to move to the right. After the triangular clamping block moves away from the positioning block, the pressure spring will push the positioning block to move to the left and clamp the short side of the next triangular clamping block. When the height adjustment of the guide roller is completed, the rear surface of the positioning block will clamp the short side of the triangular clamping block, so that the circular fixed block cannot rotate. The inability of the circular fixed block to rotate makes the square rod unable to drive the support rod to rotate, thereby fixing the threaded sleeve so that the threaded sleeve will not be displaced during the use of the conveying equipment, resulting in the inclination of the guide roller and affecting the conveying of the ore by the conveyor belt.

However, in the process of mining, when using transport supports, in the prior art, the support frames are usually fixedly installed or adjusted by snap-on connection. The height adjustment accuracy is not high, which may cause the transport structure to tilt. Long-term tilting of the transport support work may cause some supports to be easily damaged due to uneven force, thereby affecting the progress of the transportation work and causing danger.

For this reason, we urgently need to provide a kind of support for the mine conveyor belt with adjustable height.

Therefore, it is necessary to design a height-adjustable mine conveyor belt support that is highly practical and can effectively and accurately adjust the height of the transport support.
