Description

Technical Field

[0001] This utility model relates to the field of accumulation and conveying equipment technology, and more specifically, to a hoisting trolley for accumulation and conveying equipment. Background Technology

[0002] Accumulating overhead conveyor equipment is a type of transportation equipment adapted to high-productivity, flexible production systems. It not only plays a transportation role but also runs through the entire production line, integrating sophisticated process operation, storage, and transportation functions. With the rapid development of modern logistics and transportation technology, accumulating overhead conveyor equipment has been widely used in various industries. When transporting materials, a hoisting trolley is needed to lift the materials.

[0003] In existing technology, the hoisting trolley connects or disconnects with the push block on the conveyor chain via the lifting and lowering of the front shovel, facilitating the movement of the electric trolley. A rotating roller is hinged to the lower end of the front shovel. When stopping is required, the stopper is moved to the front of the rotating roller, which slides upward along the inclined surface of the stopper. Through the hinge between the rotating roller and the front shovel, the front shovel falls, thus disconnecting from the push block. When the stopper returns to its original position, the rotating roller moves downward, and through the hinge between the rotating roller and the front shovel, the front shovel moves upward, facilitating the connection between the front shovel and the push block. However, this method has some problems in use. The hoisting trolley mainly moves by the thrust of the push block. When the rotating roller moves upward, it mainly moves upward by the inertia of the hoisting trolley itself. Sometimes, the rotating roller cannot move to the designated position, causing the hoisting trolley to reverse, which affects the use of the suspended conveyor equipment. Furthermore, when stopping the hoisting trolley, the intercepting block blocks the hoisting trolley, resulting in a large impact force. Utility Model Content

[0004] The purpose of this invention is to solve the above-mentioned problems by designing a hoisting trolley for accumulating and conveying equipment.

[0005] The technical solution of this utility model to achieve the above objectives is a hoisting trolley for accumulating and conveying equipment, including a trolley body, multiple wheel bearings installed on the upper surface of both sides of the trolley body, pulleys installed on the wheel bearings, one end of the pulleys placed in the bearing rail of the accumulating and conveying equipment, a lifting mechanism installed on the trolley body, and a deceleration mechanism installed on the trolley body.

[0006] The lifting mechanism includes a front shovel located at the front of the vehicle body that can move up and down. Transmission frames are installed on both sides of the upper end of the vehicle body. When the hoisting trolley moves to the stopper side of the accumulation and conveying equipment, the stopper can drive the front shovel to move downward through the transmission frames.

[0007] The deceleration mechanism includes a telescopic frame installed on one side of the wheel bearing, and a damping block is installed at one end of the telescopic frame, which can contact the pulley.

[0008] Furthermore, multiple guide grooves are opened on both sides of the front shovel, and guide blocks are installed on both sides of the vehicle body, with one end of the guide block extending into the guide groove.

[0009] Furthermore, the transmission frame includes a fixed plate located below the front shovel, the fixed plate is installed in the vehicle body, the front shovel and the fixed plate are connected by multiple telescopic springs, L-shaped lifting rods are installed on both sides of the front shovel, square openings are opened on both sides of the vehicle body, one end of the L-shaped lifting rod extends through the square opening to the outside of the vehicle body, and a tilting platform is installed on one side of the lower end of the L-shaped lifting rod.

[0010] Furthermore, the telescopic frame includes a support plate fixedly mounted on the wheel bearing, the support plate having a circular hole, a telescopic rod provided on one side of the pulley, the telescopic rod passing through both sides of the circular hole, a damping block located between the support plate and the pulley, the damping block being installed at one end of the telescopic rod, a telescopic plate being installed at the other end of the telescopic rod, the telescopic plate and the support plate being connected by multiple return springs, a push wheel being installed on one side surface of the telescopic plate, and trapezoidal platforms being installed on both sides of the L-shaped lifting rod.

[0011] Furthermore, a lifting rod is installed at the lower end of the vehicle body, and multiple lifting hooks are installed at the lower end of the lifting rod.

[0012] The beneficial effects of this utility model are as follows: The transmission frame is installed on both sides of the vehicle body. When the transmission frame moves to the side of the stop, the front shovel can be pushed downward by the stop and the transmission frame without moving by inertia. This ensures that the front shovel is disconnected from the push block. When it is necessary to stop, the damping block can also be moved by the telescopic frame, which makes it easier to decelerate the hoisting trolley, stop the hoisting trolley, and reduce the impact force.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0019] This utility model provides, for example Figure 1-3 The hoisting trolley shown is used for a accumulating and conveying equipment. It includes a trolley body 1. Multiple wheel bearings 2 are installed on the upper part of both sides of the trolley body 1. Pulleys 3 are installed on the wheel bearings 2. One end of the pulleys 3 is placed in the bearing rail of the accumulating and conveying equipment. A lifting mechanism and a deceleration mechanism are installed on the trolley body 1. The lifting mechanism includes a front shovel 4 that can move up and down on the front side of the trolley body 1. Transmission frames 5 are installed on both sides of the upper end of the trolley body 1. When the hoisting trolley moves to the stop on the accumulating and conveying equipment, the stop can drive the front shovel 4 to move downward through the transmission frames 5. The deceleration mechanism includes a telescopic frame 6 installed on one side of the wheel bearings 2. A damping block 7 is installed at one end of the telescopic frame 6. The damping block 7 can contact the pulley 3.

[0020] The process of stopping the hoisting trolley using this device is as follows: Under normal conditions, the front shovel 4 is located in front of the push block on the conveyor chain. The push block can push the front shovel 4 and drive the trolley body 1 to move. The wheel bearing 2 and pulley 3 can support the trolley body 1. The pulley 3 can reduce the friction when the trolley body 1 moves. When the hoisting trolley moves to the stopper side, the stopper can pull the front shovel 4 downward through the transmission frame 5, which can separate the front shovel 4 from the push block. The hoisting trolley loses its forward momentum. At the same time, the telescopic frame 6 pushes the damping block 7 to the pulley 3, which can increase the friction when the pulley 3 rotates, thereby slowing down the hoisting trolley and making it easier to stop. When it is necessary to move the hoisting trolley, the stopper is returned to its original position, which can make the front shovel 4 move upward, so that the push block can push the front shovel 4. The telescopic frame 6 drives the damping block 7 back to its original position, which is convenient for the hoisting trolley to move.

[0021] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 2 The front shovel 4 has multiple guide grooves 8 on both sides, and guide blocks 9 are installed on both sides inside the vehicle body 1. One end of the guide block 9 extends into the guide groove 8. The guide groove 8 and the guide block 9 can ensure the movement direction of the front shovel 4.

[0022] Refer to the instruction manual appendix Figure 1 Included with instruction manual Figure 2 The transmission frame 5 includes a fixed plate 10 located below the front shovel 4. The fixed plate 10 is installed inside the vehicle body 1. The front shovel 4 and the fixed plate 10 are connected by multiple telescopic springs 11. L-shaped lifting rods 12 are installed on both sides of the front shovel 4. Square openings 13 are opened on both sides of the vehicle body 1. One end of the L-shaped lifting rod 12 passes through the square opening 13 and extends to the outside of the vehicle body 1. An inclined platform 14 is installed on one side of the lower end of the L-shaped lifting rod 12.

[0023] The process of the transmission frame 5 driving the front shovel 4 to move up and down is as follows: Under normal conditions, the tilting platform 14 is pushed down by the stopper. The tilting platform 14 can drive the front shovel 4 to move down through the L-shaped lifting rod 12 and compress the telescopic spring 11. When the stopper returns to its original position, the front shovel 4 can move up under the elastic force of the telescopic spring 11.

[0024] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Included with instruction manual Figure 3The telescopic frame 6 includes a support plate 15 fixedly installed on the wheel bearing 2. The support plate 15 has a circular hole 16. A telescopic rod 17 is provided on one side of the pulley 3. The telescopic rod 17 passes through both sides of the circular hole 16. A damping block 7 is located between the support plate 15 and the pulley 3. The damping block 7 is installed at one end of the telescopic rod 17. A telescopic plate 18 is installed at the other end of the telescopic rod 17. The telescopic plate 18 and the support plate 15 are connected by multiple return springs 19. A push wheel 20 is installed on one side surface of the telescopic plate 18. Trapezoidal platforms 21 are installed on both sides of the L-shaped lifting rod 12.

[0025] The process of the telescopic frame 6 driving the damping block 7 to move is as follows: When the L-shaped lifting rod 12 moves downward, it can drive the trapezoidal platform 21 to move downward. When the inclined surface of the trapezoidal platform 21 contacts the push wheel 20, it can push the push wheel 20, the telescopic plate 18, the telescopic rod 17, and the damping block 7 towards the pulley 3, increasing the friction force and compressing the return spring 19. When the L-shaped lifting rod 12 moves upward, it can drive the trapezoidal platform 21 to move upward, so that the trapezoidal platform 21 no longer limits the push wheel 20. Then, under the elastic force of the return spring 19, the push wheel 20, the telescopic plate 18, the telescopic rod 17, and the damping block 7 are pushed back to their original positions, and the damping block 7 is separated from the pulley 3.

[0026] Refer to the instruction manual appendix Figure 1 The lower end of the vehicle body 1 is equipped with a lifting rod 22, and multiple lifting hooks 23 are installed at the lower end of the lifting rod 22. The materials can be lifted and moved by the lifting hooks 23.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
