Description

Technical Field

[0001] The utility model belongs to the technical field of transportation devices, and specifically refers to a screw type deviation adjusting idler bracket. Background Technique

[0002] As an important part of the belt conveyor system, the idler bracket is mainly used to support and guide the smooth operation of the conveyor belt, and its design directly affects the conveying efficiency and equipment maintenance cost. Traditionally, the installation of idlers mostly uses a chain hook type idler bracket. Although this structure is simple, it lacks a necessary deviation adjusting mechanism. During actual operation, due to factors such as uneven material distribution and changes in conveyor belt tension, the conveyor belt often runs off track, affecting production efficiency and equipment safety.

[0003] To solve this problem, the traditional method is to cut the idler bracket by oxyacetylene to reposition the idler hanging point, thereby adjusting the position of the conveyor belt. However, this method is not only complex in operation and poor in flexibility, but also easily damages the idler bracket and shortens its service life. Content of the Utility Model

[0004] In order to solve the above problems, the utility model proposes a screw type deviation adjusting idler bracket.

[0005] The technical solution adopted by the utility model is as follows: The utility model provides a screw type deviation adjusting idler bracket, including an idler bracket. One end of a screw is rotatably arranged on the inner side wall of the idler bracket. A sleeve is sleeved on the screw, and the screw and the sleeve are in threaded connection. A towing piece is arranged at the upper end of the sleeve, and a towing groove is opened on the towing piece. The other end of the screw is arranged outside the idler bracket.

[0006] Further, a long slot one is opened at the top end of the idler bracket, and a long slot two is opened at the bottom end of the idler bracket.

[0007] Further, an ash discharge trough is arranged at the lower end of the idler bracket.

[0008] Further, the towing piece is slidably arranged in the long slot one.

[0009] Further, the idler bracket is made of stainless steel.

[0010] Adopting the above structure, the beneficial effects obtained by the utility model are as follows:

[0011] (1) By rotating one end of the screw, the screw is driven to rotate. The rotation of the screw drives the sleeve to move, the movement of the sleeve drives the towing piece to move, and the movement of the towing piece drives the towing groove to move. By changing the idler hanging point, the deviation of the belt is adjusted to ensure that the conveyor belt always maintains the best operating state, effectively avoiding problems such as material spillage and increased equipment wear caused by the deviation of the conveyor belt.

[0012] (2) At the same time, the lead screw adjustment has high precision and can achieve millimeter-level adjustment to meet the requirements of high-precision conveying.

[0013] (3) The ash discharge chute is provided to collect the coal ash on the conveyor belt.

[0014] (4) With its flexible adjustment ability, it can quickly respond to the changes of the conveyor belt, adjust the position of the idler, and maintain the stable operation of the conveyor belt. This not only improves the production efficiency but also significantly reduces the failure rate and downtime caused by unstable conveying. BRIEF DESCRIPTION OF THE DRAWINGS
