Description

Technical Field

[0001] This utility model belongs to the technical field of material conveyor belt equipment, and in particular relates to an auxiliary support device for belt replacement. Background Technology

[0002] Currently, in the field of belt conveyor equipment for material conveying in the iron and steel metallurgy industry, belt replacement is still achieved by traction to replace old belts with new ones. For belts with inclines or in areas with limited space, belt replacement is quite difficult. At the same time, belt traction often results in uneven stress, tearing, breakage, and other phenomena, which can easily lead to safety accidents. In addition, for long belts, using traditional methods to replace belts undoubtedly increases replacement time and slows down work efficiency. Utility Model Content

[0003] The purpose of this invention is to solve the problems of difficult, time-consuming, labor-intensive, easily torn and broken, and high safety hazards associated with existing belt replacement. It provides an auxiliary support device for belt replacement, which can facilitate belt replacement, reduce belt replacement time and operation difficulty, make belt replacement more convenient and faster, improve work efficiency, and reduce the risk of safety accidents.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An auxiliary support device for belt replacement includes a support beam fixed to the tail of a belt conveyor. A horizontal traction roller is connected to the lower part of the support beam. A vertical guide roller is provided on each side of the traction roller. The upper end of the guide roller is connected to the support beam through a roller frame. An oblique fixing frame is connected between the lower end of the guide roller and the support beam. The belt to be replaced passes through the space between the support beam and the traction roller to assist in belt replacement via the traction roller, and the guide roller prevents the belt from deviating or running out.

[0006] Furthermore, the support beam is an H-shaped steel structure beam, and the traction roller is arranged parallel to the axis of the support beam.

[0007] Furthermore, the two ends of the central shaft of the traction roller are connected to the mounting base, and the mounting base is fixed to the lower surface of the support beam.

[0008] Furthermore, the upper end of the inclined fixing frame is connected to both ends of the support beam, the lower end is connected to the bottom end of the central shaft of the corresponding side of the guide roller, and the top end of the central shaft of the guide roller is connected to the roller frame.

[0009] Furthermore, the axis of the guide roller is perpendicular to the axis of the traction roller, and the distance between the two guide rollers is not greater than the length of the traction roller, so as to better limit the range of movement of the belt.

[0010] Furthermore, the side of the belt that extends out of the traction drum is designated as the front side, and the guide roller is located on the front side of the traction drum.

[0011] In the technical solution of this utility model, by adding an auxiliary roller at the tail of the belt conveyor to be replaced, the belt is pulled out with the assistance of the roller, which reduces the resistance during pulling, effectively avoids tearing and breakage, and at the same time greatly saves replacement time, reduces the difficulty of operation, improves work efficiency, makes belt replacement convenient and quick, and makes maintenance twice as effective, thus ensuring the production rhythm.

[0016] Example

[0017] To make this utility model clearer, the following description, in conjunction with the accompanying drawings, further illustrates an auxiliary support device for belt replacement according to this utility model. The specific embodiments described herein are for illustrative purposes only and are not intended to limit this utility model.

[0018] In this embodiment, the side where the belt 6 pulls out of the traction roller 2 is defined as the front side.

[0019] See Figure 1 and Figure 2 An auxiliary support device for belt replacement, characterized in that:

[0020] Includes a support beam 1 fixed to the tail of the belt conveyor. The support beam 1 is an H-shaped steel structure beam with a model of HW300×300mm and a length of 2m.

[0021] A horizontal traction roller 2 is connected to the bottom of the support beam 1. The traction roller 2 has a size of φ133mm×1200mm. The traction roller 2 is set parallel to the axis of the support beam 1. The two ends of the central shaft of the traction roller 2 are connected to the mounting base 7. The mounting base 7 is fixed to the lower surface of the support beam 1.

[0022] See Figure 1 , Figure 3Each of the two sides of the traction roller 2 is provided with a vertical retaining roller 3. The retaining roller 3 has a size of φ133mm×465mm. The retaining roller 3 is located in front of the traction roller 2. The axis of the retaining roller 3 is perpendicular to the axis of the traction roller 2. The distance between the two retaining rollers 3 is not greater than the length of the traction roller 2, so as to better limit the range of movement of the belt.

[0023] An inclined fixing frame 5 is connected between the guide roller 3 and the support beam 1. The upper end of the inclined fixing frame 5 is connected to both ends of the support beam 1, and the lower end is connected to the bottom end of the central shaft of the guide roller 3 on the corresponding side. The top end of the central shaft of the guide roller 3 is connected to the support beam 1 through the roller frame 4.

[0024] The belt 6 to be replaced passes through the gap between the support beam 1 and the traction roller 2, so as to assist the replacement of the belt 6 by the traction roller 2, and the guide roller 3 is used to prevent the belt 6 from deviating and running out.

[0025] When belt 6 is pulled by the traction device, it rolls simultaneously with the traction roller 2. The rotation of the traction roller 2 drives belt 6, providing an auxiliary force for its forward movement. When the traction force on belt 6 is uneven, belt 6 will move horizontally left and right. At this time, the guide rollers 3 on both sides can limit belt 6, restrict its range of motion, and promptly correct the belt 6 so that it remains on the traction roller 2, preventing it from deviating and running off the roller. This prevents belt 6 from breaking due to resistance during the pulling process.

[0026] This invention can effectively solve problems such as belt misalignment during replacement, high resistance leading to tearing, long replacement time for long belts, difficult replacement operation, and potential safety accidents. It enables belt replacement to be convenient and quick, making maintenance more efficient, saving replacement time, and not affecting production rhythm. It has broad prospects and significant economic benefits.

[0027] In addition to the embodiments described above, this utility model may have other implementations. All technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by this utility model.
