[0002] The industrial conveyor rack is the support structure of the conveyor belt, also known as the conveyor belt bracket. The conveyor belt bracket is used to support and fix the conveyor belt to keep it stable during transportation. During the maintenance process of the industrial conveyor rack, it may be necessary to disassemble the conveyor rack, replace parts or replace it as a whole. Therefore, it is necessary to use a lifting device, which can improve the maintenance efficiency. During the maintenance process, the conveyor rack can be quickly lifted from the original position to the specified position using the lifting device, and then the conveyor rack can be replaced and repaired. The current lifting equipment is usually provided with a strap for fixing the conveyor rack, but when the strap is fixed to the conveyor rack, the strap may be inflexible in adjusting the tightness, not firmly fixed, and easy to slide, resulting in instability of the conveyor rack during the lifting process. In addition, the strap may require complex manual operations, such as manual adjustment of the tightness, fixing and disassembly, etc. Such an operation process is time-consuming and labor-intensive, reducing the overall maintenance efficiency. Therefore, the utility model designs a lifting device for the maintenance of an industrial conveyor rack. Utility Model Content

[0027] Example

[0028] like Figure 1-4 As shown, the utility model proposes a lifting device for the maintenance of an industrial conveyor frame, including a support frame 1 and a conveying device 3, wherein the conveying device 3 functions as an industrial conveyor frame. The lower surfaces of both ends of the support frame 1 are fixedly connected with a bottom plate 16, and the function of the bottom plate 16 is to increase the contact area of ​​the bottom end of the support frame 1, so that the movement of the support frame 1 and the support of the conveying device 3 are more stable. A pair of universal pulleys 17 are fixedly connected to the lower surface of the bottom plate 16, and the universal pulley (also called a universal joint pulley) is a pulley that can withstand a large load and can achieve angle adjustment. It is mainly composed of a wheel body, a bearing, an inner and outer ring, a connecting rod and other components. Universal pulleys are widely used in various lifting equipment, conveyor lines, mechanical equipment and other fields, and have the functions of transmitting torque, changing the direction of force, and reducing labor intensity. It also includes: a through slot 12 opened on the top of the support frame 1, and a limited block 14 is fixedly connected inside the through slot 12. The function of the limited block 14 is to make the rope 13 on the winch 11 always located in the middle of the limited block 14, so that the rope 13 can transmit force more stably when bearing heavy objects, avoiding problems such as unstable center of gravity caused by the deviation of the rope 13. The limited block 14 is provided with a through hole 15 for the rope 13 to pass through. The upper surface of the support frame 1 is located just above the through slot 12 and is fixedly connected with the winch 11. The winch 11 is a mechanical device for lifting objects or pulling heavy objects. It consists of a motor, a reducer, a drum and a control system. The winch 11 can realize remote control and automatic operation, and has the advantages of simple operation and high efficiency. The winch 11 is provided with a rope 13 for pulling the conveying device 3 to lift and lower; and a clamping mechanism is provided at the bottom of the rope 13 for quickly fixing the conveying device 3 that needs to be repaired.

[0029] Further, the clamping mechanism includes a strip plate 2 connected to the bottom end of the suspension rope 13, and a pair of U-shaped clamping rods 201 for clamping the support frame 1 are fixedly connected at both ends of the strip plate 2. The function of the U-shaped clamping rods 201 is to clamp the support frame 1, thereby limiting the clamping mechanism and the driving mechanism to only move vertically when lifting. The upper surface of the strip plate 2 is fixedly connected to a connecting block 202, and the upper surface of the connecting block 202 is fixedly connected to the bottom end of the suspension rope 13. The lower surface of the strip plate 2 is fixedly connected to a rotating block 203, and the bottom end of the rotating block 203 is fixedly connected to a cross 204. A pair of clamping plates 208 for clamping the conveying device 3 are arranged at the bottom of the strip plate 2, and a pair of plugging rods 212 are fixedly connected to the middle of the pair of clamping plates 208. The function of the plugging rods 212 is to clamp the upwardly tilted conveying device 3 to prevent the conveying device 3 from escaping from the pair of clamping plates 208. The opposite ends of each pair of insertion rods 212 are sleeved with sleeves 211. A pair of L-shaped clamping rods 210 for clamping the cross 204 are fixedly connected to the upper surface of the clamping plate 208. The function of the L-shaped clamping rods 210 is to share the weight of the clamping plate 208 when clamping the conveying device 3. The lower surface of the clamping plate 208 is fixedly connected with a plurality of clamping claws 209 arranged in a linear manner and used to clamp the conveying device 3. The material of the clamping claws 209 is rubber, and rubber has good flexibility and wear resistance, which can effectively prevent scratches on the clamped industrial conveying rack. The lower surface of the cross 204 is provided with a driving mechanism for moving the pair of clamping plates 208 in the same or opposite directions.

[0030] Furthermore, the driving mechanism includes a dual-axis motor 205 connected to the lower surface of the cross 204. The dual-axis motor 205 refers to a motor with two output shafts, which can drive two different devices or components at the same time. Compared with a single-axis motor, a dual-axis motor has higher flexibility and efficiency. A pair of output shafts of the dual-axis motor 205 are fixedly connected with a screw rod 206, and the opposite ends of the screw rod 206 are fixedly sleeved with a block 213 for blocking the clamping plate 208 from moving toward the dual-axis motor 205. The function of the block 213 is to limit the clamping plate 208 from moving onto the dual-axis motor 205 to avoid limiting the clamping plate 208 from damaging the dual-axis motor 205. A pair of support blocks 207 for supporting the rotation of the ends of the screw rod 206 are fixedly connected to the lower surface of the cross 204, and the screw rod 206 is spirally connected to the clamping plate 208.

[0031] In this embodiment, when the industrial conveyor rack needs to be repaired, a lifting device such as Figure 1As shown, the universal pulley 17 at the bottom of the bottom plate 16 can make the support frame 1 easily move to the top of the conveying device 3, and then the winch 11 on the support frame 1 can be started, and the rope 13 on the winch 11 pulls the connecting block 202 to move upward, and the connecting block 202 drives the strip plate 2, the rotating block 203, the cross 204 and the pair of supporting blocks 207 at the bottom of the cross 204 to drive the clamping plate 208 to move, and then the conveying device 3 is located in the middle of the pair of clamping plates 208, and then the double-axis motor 205 at the bottom of the cross 204 is started. , a pair of output shafts of the dual-axis motor 205 drives the screw rod 206 to rotate, and one end of the pair of screw rods 206 away from the dual-axis motor 205 rotates with the support of the support block 207. Since the screw rod 206 is spirally connected to the clamping plate 208, the pair of clamping plates 208 move toward the direction of the conveying device 3 through the support of the L-shaped clamping rod 210, and finally the clamping claws 209 at the bottom of the pair of clamping plates 208 clamp the conveying device 3, and at the same time, the upper surface of the conveying device 3 is pressed against by the insertion rod 212, so that the conveying device 3 can be prevented from shaking between the pair of clamping plates 208. At this time, the hoist 11 on the support frame 1 is started again, and the hoisting rope 13 on the hoist 11 pulls the clamping mechanism and the driving mechanism to move vertically upward through the pair of U-shaped clamping rods 201, and finally the clamping mechanism clamps the conveying device 3 and moves upward to a specified height, which can facilitate the maintenance of the conveying device 3, which is quick and convenient.
