Abstract
Description
Technical Field
[0001] This utility model relates to the field of wheel-rail belt conveyor rotation technology, specifically a special rotation device for wheel-rail belt conveyors. Background Technology
[0002] Belt conveyors are one of the most important material handling equipment in my country, enabling continuous material transport. To address complex terrain and energy conservation and emission reduction requirements, a wheel-rail belt conveyor has emerged. As a crucial continuous transport device in modern industry, wheel-rail belt conveyors are widely used in material handling operations in mining, ports, power, and metallurgy industries. Wheel-rail belt conveyors use a trolley to carry the conveyor belt. The trolley runs along the wheel rail via wheel sets, and the conveyor belt and trolley move synchronously through static friction. The trolley rotates via a slewing device. When the vertical distance between the conveyor belt and the slewing device is too large, traditional slewing devices use a semi-circular trajectory, resulting in a large size, high load-bearing capacity requirements for the slewing wheels, and a complex structure. Therefore, there is an urgent need for a dedicated slewing device for wheel-rail belt conveyors that is simple in structure, easy to operate, provides stable rotation, and has strong applicability. Utility Model Content

[0004] The purpose of this utility model is achieved through the following technical solution: a special rotary device for wheel-rail belt conveyors, the device including a rotary frame and a trolley, a rotary wheel is provided on the rotary frame, and a double-layer wheel rail is provided on the side of the rotary wheel, the trolley is arranged between the double-layer wheel rail and can move along the double-layer wheel rail, the trolley is composed of a crossbeam and two wheels, the crossbeam can be designed with different structures according to different load conditions, the wheels can be made of Q235 or nylon material, and there are more material options for different conveying volumes and conveyor noise requirements, etc. By selecting appropriate structures and materials, the trolley can have a good conveyor belt support effect under different conditions, the rotary wheel is composed of a shaft, a wheel, and a bearing seat, the length of the shaft and the distance between the wheels are determined according to the bandwidth of the wheel-rail belt conveyor, and the wheel diameter can be determined according to the rotation radius of the rotary part.
[0005] The double-layer wheel and rail system includes a first wheel and rail and a second wheel and rail. The second wheel and rail are located outside the first wheel and rail, and a channel is left between them for the trolley to pass through. The tracks of the first wheel and rail are consistent with the movement path of the trolley. The spacing of the channel is determined according to the diameter of the trolley wheels.
[0006] The trolley is equipped with a U-bolt, which is connected to a wire rope. The wire rope is turned by a slewing wheel, thereby driving the trolley to turn or rotate.
[0007] The portions of the first and second wheel rails near the rotary wheel are set in an arc shape, and the arc-shaped portions of the first and second wheel rails are concentrically set. The arc radius of the second wheel rail is larger than that of the first wheel rail. The channel trajectory formed by the first and second wheel rails is particularly suitable for wheel-rail belt conveyors with large vertical height differences in the rotary device.
[0008] The bearing housing on the slewing wheel is connected to the slewing frame via a pad.
[0009] The double-layer wheel and rail system is connected to the slewing frame via connectors, increasing its stability and impact resistance.
[0010] The slewing frame consists of several supports and crossbeams.
[0011] The bottom of the rotating frame is equipped with a support plate, which is used to fix it to the ground.
[0012] A shoulder is provided on one side of the rotary frame, which is connected to the conveyor frame to support the conveyor.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0022] In one embodiment of this application:
[0023] like Figures 1 to 2 As shown, a special rotary device for wheel-rail belt conveyors includes a rotary frame 1 and a trolley 3. The rotary frame 1 is equipped with four rotary wheels 4. Two rotary wheels 4 are located at the top of the rotary frame 1 for the first turning of the wire rope, and two rotary wheels 4 are located at the bottom of the rotary frame 1 for the second turning of the wire rope. The top and bottom of the rotary frame 1 each have two rotary wheels 4, which enhances the load-bearing capacity of the rotary wheels 4 and reduces the impact of the trolley on the double-layer wheel rails 2. A set of double-layer wheel rails 2 is respectively provided on the sides of the two rotary wheels 4 at the top of the rotary frame 1. The double-layer wheel rails 2 are welded to the sides of the rotary wheels 4 using a welding process. The trolley 3 is located between the double-layer wheel rails 2 and can move along the double-layer wheel rails 2.
[0024] The double-layer wheel rail 2 is composed of angle steel and round tube. A set of double-layer wheel rail 2 includes a first wheel rail and a second wheel rail. The second wheel rail is set outside the first wheel rail and a passage is left between the second wheel rail and the first wheel rail for towing the trolley 3 to pass through. The first wheel rail is inclined in an inverted "V" shape, and the second wheel rail is inclined in an inverted "V" shape.
[0025] The trolley 3 is equipped with U-bolts, which are connected to the wire rope. The wire rope is steered by the rotary wheel 4.
[0026] The portions of the first and second wheel rails closest to the slewing wheel 4 are set in an arc shape.
[0027] Four pads 9 are welded onto the slewing frame 1, and the bearing seats on the four slewing wheels 4 are respectively bolted to the four pads 9.
[0028] Two sets of double-layer wheel rails 2 are respectively connected to two connecting parts 10 on the slewing frame 1 by bolts.
[0029] The slewing frame 1 consists of four pillars 6 and twelve crossbeams 7. The twelve crossbeams 7 are divided into three groups, each group consisting of four symmetrical profiles in pairs. The three groups are respectively set at the top, middle and bottom of the pillars 6.
[0030] The steel wire rope pulls the trolley 3 forward. The trolley 3 first runs along the first wheel rail. Since the steel wire rope can be turned by the slewing wheel 4, the steel wire rope pulls the trolley 3 to turn along the first wheel rail. The trolley 3 runs along the channel left between the second wheel rail and the first wheel rail. After running to the bottom of the first wheel rail, the trolley 3 continues to run along the second wheel rail, completing the turning or rotation of the trolley 3.
[0031] In another embodiment of this application:
[0032] Based on the previous embodiment, this embodiment improves the support column 6. Each of the four support columns 6 has a support plate 5 at its bottom, and the four support columns 6 are fixed to the ground by bolts with round holes on the four support plates 5.
[0033] Each of the four pillars 6 has a shoulder 8 on its outer side, and the conveyor frame is bolted to the shoulder 8 to support the conveyor.
[0034] The above description is merely an embodiment of this utility model. It should be understood that this utility model is not limited to the form disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge.
