Description

Technical Field

[0001] This utility model relates to the field of gantry crane technology, and in particular to a winch lifting gantry crane. Background Technology

[0002] In modern industrial production and warehousing logistics, gantry cranes, as a common material hoisting and equipment installation auxiliary device, play a key role in many scenarios due to their simple structure, convenient operation, and strong applicability. With the continuous expansion of industrial production scale and the increasing complexity of the working environment, higher requirements are placed on the flexibility, adaptability, and operating efficiency of gantry cranes. Traditional gantry cranes have certain limitations in terms of height adjustment and ease of movement, making it difficult to meet diverse production needs. Therefore, the development of a new type of winch lifting gantry crane is of great practical significance.

[0003] In existing technologies, conventional gantry cranes typically consist of a rigid main beam, fixed legs, and a simple hoisting and lifting mechanism. They rely on manual operation for load positioning. Some improved designs use electric hoists to move laterally along the main beam, and the lifting mechanism uses a traditional winch lifting structure. This structure usually has the winch installed on one side of the gantry crane column, and the winch is directly connected to the crossbeam or hook by winding a steel wire rope around it. The operator needs to manually crank the winch and use the winding and unwinding of the steel wire rope to drive the crossbeam or hook to rise and fall.

[0004] However, existing gantry cranes lack effective support and reinforcement measures when adjusting their height. After the gantry crane is adjusted in height, especially when material hoisting operations are carried out at higher heights, the overall structural stability is insufficient, and it is prone to swaying or even tilting, posing significant safety hazards and affecting the accuracy of material hoisting. In addition, when facing uneven working environments, traditional gantry cranes cannot adjust the support status according to the actual situation, further reducing the stability and reliability of the gantry crane during operation. Therefore, a winch lifting gantry crane is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a winch lifting gantry frame, which aims to improve the existing gantry frames that lack effective support and reinforcement measures when adjusting height, resulting in insufficient structural stability, easy swaying and tilting, and difficulty in adapting to uneven ground, thus affecting operational safety and lifting accuracy.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A winch lifting gantry frame includes multiple support frames, each with a crossbeam fixedly connected to its top, a winch fixedly connected to one side of each support frame, an electric hoist slidably connected inside the crossbeam, and a support assembly provided on one side of each of the multiple support frames.

[0008] The support assembly includes a fixed plate, one side of which is fixedly connected to the side wall of the support frame, and the other side of which is fixedly connected to a connecting block. A transmission frame is rotatably connected inside the connecting block. An electric push rod is rotatably connected to one side of the fixed plate. A rotating shaft is fixedly connected to the output end of the electric push rod. The rotating shaft is rotatably connected inside the transmission frame. A support rod is rotatably connected to the outer wall of the rotating shaft. A connecting frame is rotatably connected to the outer wall of the support rod. One side of the connecting frame is rotatably connected to the side wall of the fixed plate. A support plate is fixedly connected to the bottom end of the support rod. The fixed plate contains symmetrical disassembly components.

[0009] As a further description of the above technical solution:

[0010] The left-right symmetrical disassembly assembly includes a fixing block and a connecting shaft. One side of the fixing block is fixedly connected to the outer wall of the support frame, and the connecting shaft is fixedly connected to the inside of the connecting block.

[0011] As a further description of the above technical solution:

[0012] A screw is rotatably connected inside the connecting shaft, and a knob is fixedly connected to one end of the screw.

[0013] As a further description of the above technical solution:

[0014] A spring is provided at the other end of the screw. One end of the spring is fixedly connected to the side wall of the screw, and the other end is fixedly connected to the extrusion shaft.

[0015] As a further description of the above technical solution:

[0016] The fixing block has a slot inside, and the connecting shaft has a locking ball that slides inside, and the locking ball fits into the slot.

[0017] As a further description of the above technical solution:

[0018] A tapered column is fixedly connected to one end of the extrusion shaft, and the outer wall of the tapered column is in contact with the locking ball.

[0019] As a further description of the above technical solution:

[0020] One end of the tapered column is fixedly connected to a base plate, and the base plate is slidably connected inside the connecting shaft.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the transmission frame and connecting frame are driven to rotate on one side of the connecting block by an electric push rod. At the same time, the electric push rod itself also deflects synchronously, further driving the support plate to contact the ground, thereby achieving the effect of quickly supporting the support frame. This solves the problem of poor structural stability and easy swaying and tilting after the height adjustment of the traditional gantry frame, and improves the efficiency and safety of material hoisting and equipment installation.

[0023] 2. In this utility model, by rotating the knob, the screw rotates inside the connecting shaft, which further drives the conical column to squeeze the locking ball, so that the locking ball is stuck into the slot, thereby achieving the effect of quick disassembly and assembly of the support component. This solves the problem that the support component cannot be quickly replaced and maintained, and improves maintenance efficiency and flexibility. Attached Figure Description

Detailed Implementation

[0031] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 - Figure 3 The present invention provides an embodiment of a winch lifting gantry frame, comprising multiple support frames 1, each of which is fixedly connected to a crossbeam 2 at its top. Each support frame 1 is fixedly connected to a winch 3 on one side. The winch 3 facilitates quick lifting and lowering of the equipment by the user, ensuring the flexibility of the equipment. An electric hoist 4 is slidably connected inside the crossbeam 2. The electric hoist 4 is used to pull and hoist materials. Each of the multiple support frames 1 is provided with a support component on one side. The support component is used to provide additional support for the equipment and ensure the stability of the equipment's movement.

[0033] The support assembly includes a fixed plate 5, one side of which is fixedly connected to the side wall of the support frame 1. The fixed plate 5 provides stable support and connection for the support assembly. A connecting block 6 is fixedly connected to the other side of the fixed plate 5. A transmission frame 7 is rotatably connected inside the connecting block 6. An electric push rod 8 is rotatably connected to one side of the fixed plate 5. The electric push rod 8 provides power output to the support assembly, ensuring that the support assembly can respond quickly. A rotating shaft 9 is fixedly connected to the output end of the electric push rod 8. The rotating shaft 9 is rotatably connected inside the transmission frame 7. A support rod 10 is rotatably connected to the outer wall of the rotating shaft 9. A connecting frame 11 is rotatably connected to the outer wall of the support rod 10. One side of the connecting frame 11 is rotatably connected to the side wall of the fixed plate 5. A support plate 12 is fixedly connected to the bottom end of the support rod 10. The support plate 12 is in contact with the ground, thereby increasing the friction between the equipment and the ground, increasing the support area, and ensuring the overall stability of the equipment during transportation. The fixed plate 5 is equipped with symmetrical disassembly components. The disassembly components facilitate the user to disassemble and assemble the support assembly at any time for maintenance.

[0034] Specifically, when the gantry crane is being height adjusted, operating on uneven ground, or when it is prone to swaying or tilting during the hoisting of heavy objects, affecting operational stability and safety, the operator can precisely control the lifting and lowering of the gantry crane by rotating the winch 3, ensuring that the height can be adjusted according to actual needs. In this process, the electric hoist 4 plays a crucial role, providing rapid hoisting by lifting materials. Simultaneously, the output end of the electric push rod 8 pushes the rotating shaft 9, causing the connecting frame 11 and the transmission frame 7 to rotate synchronously, thereby achieving a deflection action. This mechanism causes the connecting frame 11 and the transmission frame 7 to deflect under the action of the connecting block 6, from... The support plate 12 is brought into contact with the ground, generating additional supporting friction to ensure the stability of the gantry crane during material handling. At this time, the role of the support plate 12 is particularly critical. It not only provides additional stability but also prevents unnecessary shaking of the gantry crane during material handling. When the support is no longer needed, the operator only needs to pull the rotating shaft 9 backward with the electric push rod 8. This action, through the reverse pulling force of the rotating shaft 9, causes the transmission frame 7 and the connecting frame 11 to deflect upward synchronously, driving the support plate 12 to retract quickly. This facilitates the overall movement of the gantry crane, allowing for flexible adjustment of the gantry crane and efficient material handling.

[0035] Reference Figure 4 and Figure 5 The symmetrical disassembly assembly includes a fixing block 13 and a connecting shaft 14. One side of the fixing block 13 is fixedly connected to the outer wall of the support frame 1, and the connecting shaft 14 is fixedly connected inside the connecting block 6. The fixing block 13 and the connecting shaft 14 provide stable support and connection for the disassembly assembly, ensuring its stable movement. A screw 15 is rotatably connected inside the connecting shaft 14. A knob 16, made of rubber, is fixedly connected to one end of the screw 15, allowing users to quickly drive the disassembly assembly without additional tools. A spring 17 is installed at the other end of the screw 15, providing a certain degree of support to the assembly through its elastic deformation. The elastic support ensures the stability of the component's movement. One end of the spring 17 is fixedly connected to the side wall of the screw 15, and the other end is fixedly connected to the pressing shaft 18. The fixing block 13 has a slot 21 inside. The connecting shaft 14 has a sliding connection of the locking ball 20. The locking ball 20 fits into the slot 21. Through the cooperation of the locking ball 20 and the slot 21, the component can be quickly locked and unlocked. One end of the pressing shaft 18 is fixedly connected to a tapered column 19. The outer wall of the tapered column 19 contacts the locking ball 20. The function of the tapered column 19 is to press the locking ball 20 and limit the locking ball 20 to ensure its stable locking. One end of the tapered column 19 is fixedly connected to a base plate 22, which is slidably connected inside the connecting shaft 14.

[0036] Specifically, when the gantry crane needs to frequently change work sites, temporarily cope with complex ground environments, or quickly build stable supports in emergency situations to ensure the safe and efficient operation of material hoisting and equipment installation, the operator can rotate knob 16. The rotation of knob 16 drives screw 15 to rotate synchronously inside connecting shaft 14, thereby compressing spring 17. When compressed, spring 17 undergoes elastic deformation, storing elastic potential energy to provide power for subsequent disassembly and assembly actions. At the same time as spring 17 undergoes elastic deformation, tapered column 19 also moves synchronously. The movement of tapered column 19 compresses locking ball 20, causing locking ball 20 to slide inside connecting shaft 14 and completely engage inside tapered column 19. During this process, locking ball 20 is limited, ensuring the stability of the component, thereby greatly improving the flexibility and ease of maintenance of the equipment. This allows the gantry crane to be adjusted, maintained, and repaired as needed, thereby improving overall work efficiency.

[0037] Working Principle: When using this gantry crane, the operator first rotates the winch 3 to control the lifting and lowering of the gantry crane. The electric hoist 4 can quickly lift materials. Simultaneously, the output end of the electric push rod 8 pushes the rotating shaft 9 forward, causing the transmission frame 7 and connecting frame 11 to rotate synchronously within the connecting block 6, resulting in deflection. This, in turn, causes the support plate 12 to contact the ground, generating additional supporting friction to ensure the overall stability of the gantry crane during material transport. When not needed, simply pull the rotating shaft 9 backward with the electric push rod 8. Under the pulling force, the transmission frame 7 and connecting frame 11 will deflect synchronously upward, thereby causing the support plate 12 to move synchronously. The support plate 12 can be quickly retracted, facilitating the overall movement of the gantry frame. When it is necessary to disassemble or assemble the support components, the operator can turn the knob 16, which in turn drives the screw 15 to rotate synchronously inside the connecting shaft 14, thereby compressing the spring 17. This causes the spring 17 to undergo elastic deformation and store elastic potential energy. At the same time as the spring 17 undergoes elastic deformation, the tapered column 19 will also move synchronously. When the tapered column 19 moves, it will compress the locking ball 20, causing the locking ball 20 to slide inside the connecting shaft 14 and be fully engaged inside the tapered column 19, thus limiting the locking ball 20. This achieves the effect of quick installation and disassembly, making it convenient to adjust and maintain the equipment at any time.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
