Abstract
Description
Technical Field
[0001] This utility model belongs to the field of belt conveyor unloading, and in particular relates to a device for connecting two belt conveyors that are arranged perpendicularly to each other. Background Technology
[0002] In underground or surface transportation systems in coal mines, the inability to achieve continuous and stable material transfer is a common problem when two belt conveyors are arranged at a 90° vertical angle. This contradiction has become a major technical bottleneck restricting efficient mine production.
[0003] Belt conveyors are common in coal mine transportation for long-distance material transport. When two conveyors need to transfer materials perpendicularly, some form of overlapping device is usually required, such as a corner conveyor, guide chute, or chute. Failure to overlap can lead to material blockages, spillage, and even equipment damage and reduced production efficiency.
[0004] The existing overlapping method is unstable and prone to clogging. If a corner machine is installed, it will increase the investment cost. If a guide chute is installed, it will also be prone to clogging and unstable. If a chute is installed, it is okay for downward movement, but upward movement is impossible. Utility Model Content
[0005] The purpose of this invention is to provide a device for overlapping two mutually perpendicular belt conveyors, in order to solve the problems of difficulty, easy blockage and instability when overlapping two mutually perpendicular belt conveyors.
[0006] The present invention adopts the following technical solution: a device for connecting two mutually perpendicular belt conveyors, wherein the two mutually perpendicular belt conveyors are a first belt conveyor and a second belt conveyor; the coal on the first belt conveyor needs to be unloaded onto the second belt conveyor;
[0007] The device includes:
[0008] The elevated transport frame and the support frame are arranged at an angle, with one end close to the first belt conveyor and the other end continuously tilting upward and close to the second belt conveyor. The support frame is located between the elevated transport frame and the second belt conveyor. The support frame is equipped with an unloading roller and an unloading arm. The unloading roller is used to unload coal from the first belt conveyor to the second belt conveyor.
[0009] Elevator transport racks include:
[0010] Multiple extension legs are installed vertically, with their lower ends resting on the ground of the tunnel and their upper ends extending upwards.
[0011] Multiple longitudinal beams are located on the upper side of the extension leg, and their lower sides are fixedly connected to the extension leg;
[0012] The conveyor belts, located on each longitudinal beam, are used to transport coal to the unloading arm under the support of the longitudinal beams and the drive of the unloading drum, so that the unloading arm can unload the coal onto the second belt conveyor.
[0013] Furthermore, after passing the drive roller of the first belt conveyor, the conveyor belt rests on the longitudinal beam of the elevated conveyor frame, and after passing the unloading roller, returns to the underside of the drive roller of the first belt conveyor.
[0014] Furthermore, each longitudinal beam is also equipped with idlers to support the conveyor belt.
[0015] The beneficial effects of this utility model are:
[0016] This utility model greatly reduces transportation costs by only adding a heightening transport frame and a support bracket, without the need for additional power equipment. In use, the unloading roller and unloading arm of the first belt conveyor are removed and then installed on the support bracket. The transport belt is then connected to the belt of the first belt conveyor to unload the coal from the first belt conveyor onto the second conveyor.
[0017] Because of the unloading roller, this invention prevents blockages, instability, or coal spillage in the chute or guide channel during transportation, ensuring stable transport and greatly improving the transport speed and capacity between two perpendicularly arranged belt conveyors.

[0022] This utility model discloses a device for overlapping two mutually perpendicular belt conveyors, such as... Figure 1 As shown, the two belt conveyors arranged perpendicularly to each other are the first belt conveyor 10 and the second belt conveyor 11; the coal on the first belt conveyor 10 needs to be unloaded onto the second belt conveyor 11.
[0023] The device includes: an elevated transport frame 12 and a support bracket 13. The elevated transport frame 12 is inclined and one end is close to the first belt conveyor 10. The other end of the elevated transport frame 12 is continuously inclined upward and close to the second belt conveyor 11. The support bracket 13 is located between the elevated transport frame 12 and the second belt conveyor 11. An unloading roller 14 and an unloading arm 15 are installed on the support bracket 13. The unloading roller 14 is used to unload coal from the first belt conveyor 10 onto the second belt conveyor 11.
[0024] The height-adjustable transport frame 12 includes: multiple height-adjustable support legs 16, multiple longitudinal beams 17, and a transport belt 18.
[0025] Multiple extension legs 16 are vertically arranged, with their lower ends resting on the ground of the tunnel and their upper ends extending upwards; multiple longitudinal beams 17 are located on the upper side of the extension legs 16, and their lower sides are fixedly connected to the extension legs 16.
[0026] The conveyor belt 18 is located on each longitudinal beam 17. The conveyor belt 18 is used to transport coal to the unloading arm 15 under the support of the longitudinal beam 17 and the drive of the first belt conveyor 10, so that the unloading arm 15 unloads the coal onto the second belt conveyor 11.
[0027] After passing the drive roller of the first belt conveyor 10, the conveyor belt 18 rests on the longitudinal beam 17 of the elevated transport frame 12, and after passing the unloading roller 14, returns to the underside of the drive roller of the first belt conveyor 10. Each longitudinal beam 17 is also equipped with a support roller for the belt.
[0028] Example 1
[0029] In a certain mine's 2-2 mining area, there is a problem with the DSJ80 / 40 / 2*55 belt conveyor and DTL100 / 100 / 2*355 belt conveyor failing to overlap in two perpendicular roadways. Consequently, coal cannot be successfully unloaded from the DSJ80 / 40 / 2*55 belt conveyor onto the DTL100 / 100 / 2*355 belt conveyor. The existing overlap method is unstable and prone to clogging. Installing a corner machine would increase investment costs, while installing a guide chute would also be prone to clogging and unstable. Installing a chute would work for downward movement, but upward movement would be impossible.
[0030] Modifications based on this utility model:
[0031] First, nine sets of heightening support legs 16 and longitudinal beams 17, articulated idler rollers and idler rollers are added to form a heightening transport frame 12. Then, the unloading rollers 14 and unloading arms 15 of the first belt conveyor 10 are removed and installed on the support bracket 13 to achieve the unloading height.
[0032] The modification solved the problem of overlapping between the DSJ80 / 40 / 2*55 belt conveyor and the DTL100 / 100 / 2*355 belt conveyor in the 2-2 mining area of the mine, saving the mine equipment costs.
[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
