Description

Technical Field

[0001] The utility model relates to the technical field of idler assemblies of belt conveyors, in particular to an upper and lower idler assembly for the intermediate frame of a belt conveyor. Background Art

[0002] A belt conveyor is a device that uses a continuously running conveyor belt to transport materials. It is widely used in industries such as industry, mining, construction, and logistics. The belt conveyor mainly consists of the following parts:

[0003] Conveyor belt: It runs in a loop between the two end drums and is responsible for carrying and transporting materials. It is usually made of wear-resistant rubber or other synthetic materials.

[0004] Drums: Include driving drums and non-driving drums, which are used to drive the movement of the conveyor belt. The driving drum is powered by an electric motor.

[0005] Frame: The frame that supports the entire conveyor structure, usually made of steel.

[0006] Tensioning device: Adjusts the tension of the conveyor belt to ensure its normal operation and prevent slipping or falling off.

[0007] Support rollers: Provide support below the conveyor belt to reduce friction and maintain the stability of the belt.

[0008] During the transportation and use of the existing belt conveyor drive belt, it is generally supported by the upper and lower idlers inside the support frame. However, when materials are placed on the surface of the conveyor belt for transportation, the self-weight of the materials is transmitted to the surface of the idlers through the conveyor belt, resulting in long-term compression and damage of the idler assembly, and it is unable to continue to support the conveyor belt for transportation. This increases the pressure on the conveyor belt itself. Therefore, we propose an upper and lower idler assembly for the intermediate frame of a belt conveyor. Content of the Utility Model

[0009] The main purpose of the utility model is to solve the technical problems existing in the above-mentioned prior art, and provide an upper and lower idler assembly for the intermediate frame of a belt conveyor.

[0010] To achieve the above object, the present utility model adopts the following technical solutions. A belt conveyor intermediate frame upper and lower idler assembly includes two sets of support frames supported and connected in cooperation through connecting members. Support mechanisms are arranged at both the upper and lower positions between the two sets of support frames. One ends of multiple support mechanisms at the top corresponding to the support frames are movably connected to the support frames through hinge mechanisms. A round shaft is fixedly installed at the end of the support mechanism far from the support frame. An idler assembly is movably assembled outside the round shaft. Multiple idler assemblies are supported together by a conveyor belt sleeved outside. A fixed seat is fixedly installed at the top of the support frame. An internal groove is opened inside the fixed seat. A wire groove penetrating the inside of the internal groove is opened at the top of the fixed seat. A sliding member is arranged inside the internal groove. A connecting rope that penetrates the wire groove and supports and suspends the support mechanism is fixedly connected to the top of the sliding member.

[0011] As a preferred technical solution of the present utility model, a connecting spring is fixedly installed at the bottom of the sliding member. The bottom of the connecting spring is fixedly connected to the bottom inside the internal groove. A wire guide cover is fixedly installed at the top of the fixed seat. The outer wall of the connecting rope is supported and fitted with the inner wall of the wire guide cover.

[0012] Furthermore, after the idler assembly is pressed, the connecting rope can be pulled through the support mechanism, so that the sliding member inside the internal groove cooperates with the connecting spring to elastically pull and buffer.

[0013] As a preferred technical solution of the present utility model, the inside of the wire groove is an elliptical hollow wall surface, and the wire guide cover is an arc-shaped hollow curved wall surface.

[0014] As a preferred technical solution of the present utility model, the idler assembly includes an idler main body. Multiple notches are opened on the outer wall of the idler main body. A replacement assembly for disassembly and replacement is arranged inside the notches. Pull handles are fixedly installed on both the left and right sides of the replacement assembly.

[0015] As a preferred technical solution of the present utility model, an installation hole is opened at the bottom inside the notch. A mounting rod penetrating inside the installation hole is fixedly installed at the bottom of the replacement assembly corresponding to the installation hole. The outer wall of the mounting rod is tightly fitted and assembled with the inner wall of the installation hole through multiple fastening gaskets.

[0016] The present utility model provides a belt conveyor intermediate frame upper and lower idler assembly. It has the following beneficial effects:

[0017] 1. For the upper and lower idler assemblies of the intermediate frame of this belt conveyor, multiple idler assemblies between the two sets of support frames can support and hold the conveyor belt and cooperate with the connecting rope to pull and buffer. Generally, when the driving belt of the existing belt conveyor is in use during transportation, it is supported by the upper and lower idlers inside the support frame. However, when there are materials placed on the surface of the conveyor belt during transportation, the self-weight of the materials is transmitted to the surface of the idlers through the conveyor belt, resulting in the idler assemblies being damaged due to long-term compression and being unable to continue to support and hold the conveyor belt, increasing the pressure on the conveyor belt itself. And this idler assembly is movably assembled with the round shaft, and one end of the round shaft is movably connected to the support frame through the support mechanism and the hinge mechanism. At this time, when the idler assembly is compressed, the idler assembly will stretch and move the connecting rope through the support mechanism, and the bottom of the connecting rope inside the fixed seat will pull the sliding part upward, and the connecting spring itself can press down and buffer the pressure borne by the idler assembly through its own elasticity, avoiding the direct force on the idler assembly itself, so as to improve the support fitting of the idler assembly and avoid the damage of the conveyor belt without support.

[0018] 2. For the upper and lower idler assemblies of the intermediate frame of this belt conveyor, when the idler body is used to support and hold the inner surface of the conveyor belt for a long time, the surface of the idler body is prone to damage during friction. And a set of matching replacement components are movably assembled on the surface of the idler body through multiple notches, and multiple replacement components are arranged around the outer wall of the idler body. At this time, when the idler body is in use, after the outer wall of the idler body is damaged by friction, the damaged replacement components at multiple positions can be taken out and replaced by pulling the pull handle, and the installation rod at the bottom of the replacement component can be inserted and fastened into the installation hole through the fastening gasket, so as to achieve the effect of conveniently and directly replacing the damaged part of the idler body without replacing the whole idler body, saving costs.
