Description

Technical Field

[0001] This utility model belongs to the field of equipment maintenance technology, and relates to a lifting device, particularly a lifting device for replacing belt conveyor rollers. Background Technology

[0002] In the field of coal transportation machinery, idlers are an indispensable and important component of belt conveyors. They play a role in supporting the belt. Multiple idlers are usually installed at intervals on belt conveyors, resulting in a large number, many types, and easy wear and tear. Once a failure occurs, it will directly affect production.

[0003] Currently, replacing damaged idler rollers is a rather cumbersome process, involving either manually prying up the belt with a crowbar or having a worker crawl under the belt and arch it using their back. These existing methods are inefficient, labor-intensive, and pose safety hazards.

[0004] Therefore, it is essential to design a device suitable for replacing idlers by making clever use of the idler frame's own structure, while ensuring safety and minimizing the impact on production. Summary of the Invention

[0005] The purpose of this utility model is to provide a lifting device for replacing belt conveyor rollers that has a scientific and reasonable structural design, is easy to operate, improves replacement efficiency, reduces labor intensity, is safe and reliable, and is easy to implement.

[0006] The technical problem solved by this utility model is achieved through the following technical solution:

[0007] A lifting device for replacing idler rollers of a belt conveyor is characterized by comprising two opposing lifting brackets and a belt support bracket horizontally installed on the upper part of the two lifting brackets. The lifting bracket includes a mounting plate, an installation platform, and a lifting device. The mounting plate includes a mounting part, a vertical connecting part, and a platform mounting part. The upper end face of the mounting part is provided with an upwardly protruding clip, and the lower end face of the mounting part is provided with a hanging groove. The rear end of the mounting part is connected to the horizontally arranged platform mounting part through the vertical connecting part. An installation platform is provided on the platform mounting part, and a lifting device for driving the belt support bracket to rise and fall is installed on the installation platform.

[0008] Furthermore, it also includes a positioning steel plate, wherein the hanging groove is an arc-shaped groove, and a positioning steel plate is provided along the inner wall of the arc-shaped groove, the width of which is greater than the width of the hanging groove.

[0009] Furthermore, the belt support frame is composed of a support plate, a connecting vertical plate and a top plate. The support plate is installed on the upper end of the connecting vertical plate. The support plate has a structure that is horizontal in the middle and inclined to the outside and upward at both ends. The top plate is welded to the bottom two ends of the connecting vertical plate. The top plate is connected to the top rod of the lifting device.

[0010] Moreover, the lifting device is a screw jack.

[0011] The advantages and beneficial effects of this utility model are as follows:

[0012] 1. This lifting device, used for replacing idler rollers on belt conveyors, is hung on the bottom of the belt on the idler frame during use. The lifting device then lifts the belt support frame, thereby lifting the belt. This device replaces the traditional method of manually lifting the belt, greatly improving the efficiency of idler roller replacement and reducing labor intensity while ensuring operational safety.

[0013] 2. The present invention has a scientific and reasonable structural design, and has the advantages of convenient operation, improved replacement efficiency, reduced labor intensity, safety and reliability, and easy implementation. It is a highly innovative lifting device for replacing conveyor belt rollers. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described in detail below through specific embodiments. The following embodiments are only descriptive and not limiting, and should not be used to limit the protection scope of the present invention.

[0023] This lifting device for replacing conveyor rollers is installed on a roller frame during use. The roller frame consists of a cylindrical crossbeam 15, side supports 19, intermediate supports 16, and a base. The bases are arranged opposite each other on the left and right sides. Side supports are vertically installed on each base. A crossbeam connects the two side supports. Two intermediate supports are spaced apart at the center of the crossbeam. The intermediate supports are N-shaped structures made of bent steel plates. An installation port is provided at the top of the N-shape. An installation port is also provided at the top of the side supports. A roller 14 is installed between the two installation ports. The belt 18 is supported on the roller support.

[0024] An innovative feature of a lifting device for replacing idler rollers on a belt conveyor is that it includes two opposing lifting brackets and a belt support frame 1 horizontally installed on the upper part of the two lifting brackets. The lifting bracket includes a mounting plate 4, an installation platform 3, and a lifting device 2, which is a screw jack. The mounting plate includes a mounting part 6, a vertical connecting part 8, and a platform mounting part 9. The mounting part and the vertical connecting part are connected by an arc curve. The upper end of the mounting part has an upwardly protruding clip 5, and the lower end of the mounting part has a hanging groove 10. The rear end of the mounting part is connected to a horizontally arranged platform mounting part through the vertical connecting part. An installation platform is provided on the platform mounting part, and a lifting device for driving the belt support frame to rise and fall is installed on the installation platform.

[0025] To ensure the stability of the hanging groove on the crossbeam, this utility model also includes a positioning steel plate 7. The hanging groove is an arc-shaped groove, and a positioning steel plate is provided along its inner wall inside the arc-shaped groove. The width of the positioning steel plate is greater than the width of the hanging groove to increase the contact area between the device and the crossbeam.

[0026] The belt support frame consists of a support plate 13, a connecting vertical plate 12, and a top plate 11. The support plate is installed on the upper end of the connecting vertical plate. The support plate has a structure that is horizontal in the middle and inclined outward and upward at both ends. The top plate is welded to the bottom ends of the connecting vertical plate. The top plate is connected to the top rod of the lifting device.

[0027] During on-site operation, insert the mounting part of the mounting plate into the middle support of the roller frame: rotate the mounting groove along the surface of the crossbeam until the clip on the mounting part is engaged on the outer side of the middle support. At this time, slowly release the hand. Under the action of the weight of the lifting device 17 itself, the present invention is stably installed on the roller frame. At this time, the front, back, up and down directions of the lifting device are in a fixed state.

[0028] After the lifting device is installed, manually adjust the screw jack to lift the belt support frame to a suitable height, and then replace the damaged idler roller. After the idler roller is replaced, disassemble and store the device in the reverse order of installation.

[0029] Although embodiments and drawings of the present invention have been disclosed for illustrative purposes, those skilled in the art will understand that various substitutions, variations and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
