Description

Technical Field

[0001] This utility model relates to the technical field of mining equipment, and in particular to an auxiliary support device for quick maintenance of idler rollers and ground rollers. Background Technology

[0002] Idler rollers or ground rollers are typically installed on mine belt conveyor or winch lines to reduce the frictional resistance of the belt or wire rope. After prolonged use, the idler rollers or ground rollers will develop deep grooves due to wear from the belt or wire rope, requiring maintenance and welding to restore them to their operational requirements.

[0003] When performing maintenance welding, large idler rollers and floor rollers are difficult for a single person to move; usually, two people are needed to move them. Improper operation can easily result in toe injuries. Therefore, maintenance work is time-consuming, labor-intensive, and poses safety risks. Furthermore, squatting on the ground during maintenance and welding is not only inconvenient but also easily leads to fatigue. Therefore, there is an urgent need for an auxiliary support device for quickly inspecting and repairing idler rollers and floor rollers. Utility Model Content

[0004] To address the technical problem that idler rollers or floor rollers are heavy and often require manual handling, and that personnel are prone to fatigue when squatting on the ground during maintenance and welding, this utility model provides an auxiliary support device for the rapid maintenance of idler rollers and floor rollers.

[0005] To address the above problems, the technical solution adopted by this utility model is: an auxiliary support device for quick inspection and maintenance of idler rollers and ground rollers, comprising:

[0006] The support frame is triangular in shape, with two symmetrically arranged beams connected by a bottom crossbeam at the bottom and an upper crossbeam at the top, forming the main body of the support frame.

[0007] An arc-shaped roller frame is set on one side of the support frame, serving as a rolling frame to enable the main body of the support frame to complete the actions of falling down and standing up;

[0008] Auxiliary bearings are symmetrically distributed in pairs on both sides of the upper crossbeam;

[0009] The idler roller support frame is located on both sides of the support frame body above the auxiliary bearing;

[0010] The fixing bolt passes through the roller support frame, with one end placed on the outside of the roller support frame and the other end locked to the roller shaft inside the roller support frame on both sides by threads.

[0011] Furthermore, the support frame is formed by the bottom rod and the side rods on both sides forming a triangle.

[0012] Furthermore, the bottom crossbeam is mounted on the bottom rod of the support frame.

[0013] Furthermore, the arc-shaped roller frame is an arc-shaped bent rod, with its two ends fixedly connected to the upper and lower ends of the side rod on one side of the support frame, respectively.

[0014] Furthermore, the idler roller receiving frame includes an outer clamping plate with a hole in the center for fixing bolts to pass through, and a receiving block on the inner side of the clamping plate with a U-shaped receiving groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This device can help workers easily fix and lift idler rollers and floor rollers that previously required two people to lift, to a height that is easy for workers to operate. At the same time, during maintenance, the idler rollers and floor rollers under maintenance can be rotated 360° around the axis through the auxiliary bearing, allowing operators to quickly and easily repair the idler rollers and floor rollers, reducing the number of workers, reducing the maintenance load, improving maintenance efficiency, and ensuring maintenance safety.

[0020] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of an auxiliary support device for quick maintenance of idler rollers and floor rollers.

[0021] like Figure 1 and Figure 2 As shown, an auxiliary support device for quick maintenance of idler rollers and ground rollers includes a support frame 1, an arc-shaped roller frame 2, auxiliary bearings 3, an idler roller receiving frame 4, and fixing bolts 5. The support frame 1 is triangular, with two symmetrically arranged components connected by a bottom crossbeam 11 at the bottom and an upper crossbeam 12 at the top, serving as the main body of the support frame. The arc-shaped roller frame 2 is located on one side of the support frame 1, serving as a rolling frame to enable the main body of the support frame to fall down and stand upright. The auxiliary bearings 3 are symmetrically distributed in pairs on both sides of the upper crossbeam 12. The idler roller receiving frame 4 is located on both sides of the main body of the support frame, corresponding to the position above the auxiliary bearings 3. The fixing bolts 5 pass through the idler roller receiving frame 4, with one end placed on the outside of the idler roller receiving frame 4 and the other end locked to the idler roller shaft inside the idler roller receiving frames 4 by threads.

[0022] In this embodiment, the support frame 1 is formed by a bottom rod and two side rods, creating a triangle. The bottom crossbeam 11 is connected to the bottom rod of the support frame 1. The arc-shaped roller frame 2 is an arc-shaped bent rod, with its two ends fixedly connected to the upper and lower ends of one side rod of the support frame 1, respectively. The idler roller receiving frame 4 includes an outer clamping plate with a hole in the center for the fixing bolt 5 to pass through. A receiving block is provided on the inner side of the clamping plate, and the receiving block has a U-shaped receiving groove.

[0023] The auxiliary support device in this embodiment uses a triangular structure to maintain the stability of the support frame body. The support frame body can be laid down by the arc-shaped roller 2, which makes it easy and labor-saving to install and remove the idler roller 6 or the ground roller. At the same time, after the idler roller 6 or the ground roller is fixed by the fixing bolt 5, the auxiliary bearings 3 on both sides of the upper crossbeam 12 allow the idler roller 6 and the ground roller to rotate flexibly on them, reducing the maintenance load, improving maintenance efficiency, and ensuring maintenance safety.

[0024] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
