Description

Technical Field

[0001] This utility model belongs to the field of material handling and bearing technology, and in particular relates to a bearing structure for idler roller handling equipment. Background Technology

[0002] Idler rollers are crucial components of belt conveyors, primarily used to support the conveyor belt and the weight of the materials, ensuring smooth belt operation. They consist of bearing housings, bearings, and baffles, utilizing rolling friction instead of sliding friction to reduce energy loss and transmitting power by driving the belt. The idler rollers must operate flexibly and reliably to minimize friction between the conveyor belt and the rollers, playing a key role in the lifespan of the conveyor belt.

[0003] Common idler roller handling equipment uses a support structure that places the idler roller on a support structure and defines its position. The idler roller is then moved upwards to a transport vehicle or higher by controlling the vertical movement of the support structure. However, in actual use, there is often a gap between the support structure and the location to be transported, making it inconvenient to move the trolley. External force is required to move the idler roller from the support structure to its designated position. Therefore, we provide a support structure for idler roller handling equipment to solve the aforementioned technical problems. Utility Model Content

[0004] The purpose of this utility model is to provide a load-bearing structure for idler roller handling equipment. Through the specific structural design of the load-bearing support component and the lifting adjustment component, the problems in the background art mentioned above are solved.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a load-bearing structure for a roller conveying device, including a load-bearing support assembly. The load-bearing support assembly includes a fixedly installed load-bearing support frame, which has a U-shaped frame structure. A vertically movable conveying load-bearing frame is slidably installed inside the load-bearing support frame. The conveying load-bearing frame has a U-shaped frame structure, and a connecting support plate is rotatably connected to the bottom of the conveying load-bearing frame via a first rotating shaft. A support upright plate is fixedly connected to the bottom of the load-bearing support frame, and a connecting transmission roller is rotatably connected to the upper surface of the support upright plate via an ear plate. A lifting adjustment assembly is fixedly connected between the load-bearing support frame and the conveying load-bearing frame. The lifting adjustment assembly includes a first lifting frame fixedly connected to the bottom of the load-bearing support frame and a second lifting frame fixedly connected to the lower surface of the conveying load-bearing frame. Two first transmission links and two second transmission links are symmetrically rotatably connected between the first lifting frame and the second lifting frame, and the first transmission links are rotatably connected to the corresponding second transmission links.

[0006] The present invention is further configured such that a transport support plate is rotatably connected to the bottom of the transport support frame via a second rotating shaft, and an electric adjusting rod is rotatably connected to each of the two inner sidewalls of the transport support frame via a first extension block. Two second extension blocks are symmetrically fixedly connected to one side of the transport support plate, and the output end of the electric adjusting rod is hinged to the second extension block.

[0007] The present invention is further configured such that guide slides are fixedly connected to the opposite two sides of the bearing support frame, and extension transmission blocks are fixedly connected to the opposite two sides of the transport bearing frame. The extension transmission blocks slide in cooperation with the corresponding guide slides, and an elastic element is fixedly connected between the connecting support plate and the transport bearing frame.

[0008] The present invention is further configured such that two guide slide rods are symmetrically fixedly connected between the two inner side walls of the first lifting frame, a lifting transmission rod is slidably arranged between the two guide slide rods, and a drive screw is rotatably connected between the first lifting frame and the two inner side walls, and the drive screw and the lifting transmission rod are threaded together.

[0009] The present invention is further configured such that one end of the first transmission link is rotatably connected to one side of the lifting transmission link; two first extension seats are symmetrically fixedly connected to the lower surface of the second lifting frame; the other end of the first transmission link is rotatably connected to the corresponding first extension seat; two second extension seats are symmetrically fixedly connected to the lower surface of the second lifting frame; one end of the second transmission link is rotatably connected to the corresponding second extension seat; and two third extension seats are symmetrically fixedly connected to the upper surface of the first lifting frame; the other end of the second transmission link is rotatably connected to the corresponding third extension seat.

[0010] The present invention has the following advantages: 1. By setting up a load-bearing support assembly, the present invention controls the extension of two electric adjusting rods, and rotates the transport support plate until its end is in contact with the ground. The trolley pushes the roller into the transport load-bearing frame. During the upward movement of the transport load-bearing frame, the connecting support plate rotates and extends outward along the circumferential side of the connecting transmission roller until one end of the connecting support plate is in contact with the transport position. The trolley transports the roller to the corresponding position along the connecting support plate, which facilitates the transport of the roller and avoids the time-consuming and laborious manual handling.

[0011] 2. This utility model, by setting up a lifting adjustment component, controls the rotation of the drive screw. Under the threaded cooperation between the drive screw and the lifting transmission rod, the lifting transmission rod slides along the circumferential side of the guide slide rod, and drives the first transmission connecting rod to rotate. The second transmission connecting rod rotates synchronously, thereby changing the distance between the first lifting frame and the second lifting frame, thus realizing the adjustment of the position and height of the connecting support plate, and facilitating the control of the roller to move up and down for transfer.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0023] Please see Figure 1-6This utility model is a load-bearing structure for a roller conveying equipment, including a load-bearing support assembly 1. Specifically, the load-bearing support assembly 1 includes a fixedly installed load-bearing support frame 101, which has a U-shaped frame structure. Inside the load-bearing support frame 101, a vertically movable conveying load-bearing frame 102 is slidably installed. The conveying load-bearing frame 102 also has a U-shaped frame structure. The bottom of the conveying load-bearing frame 102 is rotatably connected to a connecting support plate 103 via a first rotating shaft. The bottom of the load-bearing support frame 101 is fixedly connected to a support upright plate. The upper surface of the support upright plate is rotatably connected to a connecting transmission roller 104 via an ear plate.

[0024] Furthermore, a lifting adjustment assembly 2 is fixedly connected between the load-bearing support frame 101 and the transport load-bearing frame 102. The lifting adjustment assembly 2 includes a first lifting frame 201 fixedly connected to the bottom of the load-bearing support frame 101 and a second lifting frame 202 fixedly connected to the lower surface of the transport load-bearing frame 102. Two first transmission links 203 and two second transmission links 204 are symmetrically rotatably connected between the first lifting frame 201 and the second lifting frame 202. The first transmission links 203 and the corresponding second transmission links 204 are rotatably connected.

[0025] The operation process of this embodiment is as follows: The roller to be transported is placed on the trolley and pushed onto the transport carrier frame 102. The first transmission link 203 and the second transmission link 204 are controlled to rotate synchronously, so that the included angle between the first transmission link 203 and the corresponding second transmission link 204 changes, thereby gradually increasing the distance between the first lifting frame 201 and the second lifting frame 202. The transport carrier frame 102 moves upward. During this process, although the external force restriction on the connecting support plate 103 gradually weakens, the connecting support plate 103 rotates and gradually slides outward along the circumferential side of the connecting transmission roller 104. When the transport carrier frame 102 rises to be level with the transport position and the lower end of the transport carrier frame 102 is level with the connecting transmission roller 104, the end of the connecting support plate 103 is in contact with the transport position, which facilitates the trolley to drive the roller to be transported from the connecting support plate 103 to the transport position. Specific Implementation Example 2

[0027] Please see Figure 1-6 Based on the specific embodiment one, specifically, the bottom of the transport support frame 102 is rotatably connected to the transport support plate 105 via the second rotating shaft. The transport support frame 102 is rotatably connected to the electric adjustment rod 106 via the first extension block on both inner side walls. Two second extension blocks are symmetrically fixedly connected to one side of the transport support plate 105. The output end of the electric adjustment rod 106 is hinged to the second extension block.

[0028] Furthermore, the support frame 101 is fixedly connected to guide slides 107 on both sides, and the transport support frame 102 is fixedly connected to extension transmission blocks 108 on both sides. The extension transmission blocks 108 slide with the corresponding guide slides 107, and the connecting support plate 103 is fixedly connected to the transport support frame 102 with an elastic element. In the initial state, under the restriction of the support plate, the elastic element is in a compressed state, and the connecting support plate 103 is in contact with the side of the transport support frame 102.

[0029] Furthermore, two guide slide rods 205 are symmetrically fixedly connected between the first lifting frame 201 and its two inner sidewalls, and a lifting transmission rod 206 is slidably arranged between the two guide slide rods 205. A drive screw 207 is rotatably connected between the first lifting frame 201 and its two inner sidewalls. The drive screw 207 and the lifting transmission rod 206 are threaded together. A drive motor is fixedly installed on one side of the first lifting frame 201, and the output shaft of the drive motor is fixedly connected to the drive screw 207.

[0030] Furthermore, one end of the first transmission link 203 is rotatably connected to one side of the lifting transmission link 206, and two first extension seats are symmetrically fixedly connected to the lower surface of the second lifting frame 202, and the other end of the first transmission link 203 is rotatably connected to the corresponding first extension seat; two second extension seats are symmetrically fixedly connected to the lower surface of the second lifting frame 202, and one end of the second transmission link 204 is rotatably connected to the corresponding second extension seat; two third extension seats are symmetrically fixedly connected to the upper surface of the first lifting frame 201, and the other end of the second transmission link 204 is rotatably connected to the corresponding third extension seat.

[0031] The operation process of this embodiment is as follows: The two electric adjusting rods 106 are controlled to extend synchronously, pushing the transport support plate 105 to rotate until one end of the transport support plate 105 is in contact with the ground. The roller is placed on the trolley and restrained. The trolley is pushed so that it moves along the transport support plate 105 into the transport carrying frame 102. The two electric adjusting rods 106 are controlled to retract synchronously until the transport support plate 105 is in contact with the side of the transport carrying frame 102 away from the connecting support plate 103. The drive motor is started, driving the drive screw 207 to rotate. Under the threaded engagement of the drive screw 207 and the lifting transmission rod 206, the lifting transmission rod 206 slides along the circumferential side of the guide slide rod 205 and moves towards the transport support plate 105. During the movement of the lifting transmission rod 206, one end of the first transmission connecting rod 203 moves synchronously. 03 rotates and drives the second transmission link 204 to rotate synchronously, causing the angle between the second transmission link 204 and the corresponding first transmission link 203 to change, so that the distance between the first lifting frame 201 and the second lifting frame 202 gradually increases, and the transport carrying frame 102 moves upward. During this process, the extension transmission block 108 moves upward along the guide slide 107 synchronously, and although the external force restriction on the connecting support plate 103 gradually weakens, under the elastic recovery action of the elastic element, the connecting support plate 103 rotates and gradually slides outward along the circumferential side of the connecting transmission roller 104. When the transport carrying frame 102 rises to be level with the transport position and the lower end of the transport carrying frame 102 is level with the connecting transmission roller 104, the end of the connecting support plate 103 is in contact with the transport position, which facilitates the trolley to drive the roller to be transported from the connecting support plate 103 to the transport position.
