Description

Technical Field

[0001] This invention relates to the field of cranes, and more particularly to an auxiliary disassembly and assembly device for crane structural components. Background Technology

[0002] The development of traction devices for crane assembly and disassembly stems from the ongoing pursuit of safety, efficiency, and regulatory compliance in the construction industry. As construction projects expand in scale and become more complex, tower cranes, as key lifting equipment, face higher safety risks and operational challenges during assembly and disassembly. To ensure the safety of personnel and equipment while improving the efficiency and accuracy of assembly and disassembly operations, specialized traction devices have emerged.

[0003] A crane is a lifting device widely used in construction engineering. Its main structure consists of a tower, boom, counterweight boom, and crane motor. The main function of a tower crane is to lift heavy objects and make precise positioning and adjustments during the lifting process. The lifting capacity, working radius, lifting torque and other parameters of a tower crane vary depending on the model and application.

[0004] The patent application with publication number CN222877595U in the prior art describes a method that uses a starting motor to drive a transmission shaft through a drive sprocket, a driven sprocket, and a chain. This causes a gear to rotate under force, and through the cooperation of the gear plate and wheels, it can stably pull a standard section to the outside of the disassembly and assembly device. This achieves the effect of quickly and orderly pulling tower crane components, solving the problem that when tower cranes are disassembled and assembled, there is a lack of suitable traction devices, and components are prone to collisions and scratches during transportation, increasing maintenance and replacement costs, thus improving disassembly and assembly efficiency.

[0005] When towing the standard section, motor two is started. Motor two drives the disc to rotate through gear two and gear ring, which causes the transmission rod to be stressed and drive the connecting rod and the fixing block to clamp the standard section. This achieves the effect of better fixing the standard section and preventing it from falling off when towing in bad weather. It solves the problem that bad weather will cause a large impact and shaking on the standard section being towed. Without the fixing component, the standard section is easy to fall off, causing serious safety accidents, thus improving safety.

[0006] However, the current auxiliary dismantling traction device is of fixed length, and the length of the entire traction device cannot be adjusted when placing and moving structural components of different cranes.

[0007] Therefore, it is necessary to provide an auxiliary disassembly and assembly device for crane structural components to solve the above-mentioned technical problems. Summary of the Invention

[0008] This invention provides an auxiliary disassembly and assembly device for crane structural components, which solves the problem that current auxiliary disassembly traction devices have a fixed length, making it impossible to adjust the length of the entire traction device when placing and transporting structural components of different cranes.

The two fixed seats are respectively connected to the two ends of the hydraulic push rod and connected to the bottom of the movable seat and the adjusting seat.

[0012] The mounting bracket is mounted on the surface of the movable base;

[0013] The two fixing brackets are respectively connected to both sides of the mounting bracket;

[0014] The two movable components are respectively disposed between the two fixed frames and the adjusting seat.

[0036] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0037] First Embodiment

[0038] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of an auxiliary disassembly and assembly device for crane structural components provided by the present invention; Figure 2 for Figure 1 The enlarged schematic diagram of part A shown below; Figure 3 for Figure 1 The enlarged schematic diagram of section B is shown below; Figure 4 for Figure 1 The diagram shows a three-dimensional structural schematic of the auxiliary disassembly and assembly device. An auxiliary disassembly and assembly device for crane structural components includes:

[0039] 1. Movable base; 2. Adjustable base; 3. Two pushing devices; 4. Mounting bracket; 6. Two fixed brackets; and 5. Two moving components.

[0040] Two pushing devices 3 are symmetrically arranged between the movable seat 1 and the adjusting seat 2. Each pushing device 3 includes a hydraulic pushing rod 31 and two fixed seats 32. The two fixed seats 32 are respectively connected to the two ends of the hydraulic pushing rod 31 and connected to the bottom of the movable seat 1 and the adjusting seat 2.

[0041] The mounting bracket 4 is mounted on the surface of the movable base 1;

[0042] The two fixing brackets 6 are respectively connected to both sides of the mounting bracket 4;

[0043] The two movable components 5 are respectively disposed between the two fixed frames 6 and the adjusting seat 2.

[0044] The movable component 5 includes a connecting rod 51, a movable block 52, and a movable groove 53. The connecting rod 51 is connected to one end of the fixed frame 6, and the movable block 52 is connected to the bottom of the connecting rod 51.

[0045] The movable groove 51 is formed on the surface of the adjusting seat 2.

[0046] The mounting frame 4 is provided with a plurality of extrusion devices 7. Each extrusion device 7 includes a hydraulic telescopic component 71 and an extrusion plate 72. The hydraulic telescopic component 71 is mounted on the mounting frame 4, and the extrusion plate 72 is connected to one end of the hydraulic telescopic component 71.

[0047] When the overall length of the device needs to be adjusted according to the dimensions of the crane structural components, two symmetrically arranged pushing devices 3 between the movable seat 1 and the adjusting seat 2 are activated. The hydraulic push rod 31 in the pushing device 3 extends or retracts under hydraulic drive, driving the movable seat 1 and the adjusting seat 2 to move relative to each other through the fixed seats 32 at both ends. During this process, the movable components 5 connected to the fixed frames 6 on both sides of the mounting frame 4 move synchronously. The moving block 52 at the bottom of the connecting rod 51 slides smoothly along the moving groove 53 opened on the surface of the adjusting seat 2, ensuring that the movable seat 1 and the adjusting seat 2 remain laterally aligned during the length adjustment process and avoiding displacement.

[0048] After placing the crane structural component on the surface of the mounting frame 4, the multiple pressing devices 7 on the mounting frame 4 are activated. The hydraulic telescopic component 71 extends and pushes the pressing plate 72 connected to it to move towards the structural component until the pressing plate 72 is tightly attached to the surface of the structural component. Through multi-directional pressing force, the structural components of different sizes are firmly clamped, preventing shaking or displacement during handling or disassembly.

[0049] The inner side of the extrusion plate 72 is covered with a nitrile rubber pad, which can increase the friction with the surface of the structural component and improve the clamping stability. On the other hand, it can prevent the metal extrusion plate 72 from directly contacting the surface of the structural component, preventing scratches on the surface coating of the structural component or damage from metal impacts. Multiple extrusion devices 7 can be controlled independently according to the shape contour of the structural component.

[0050] Compared with related technologies, the auxiliary disassembly and assembly device for crane structural components provided by the present invention has the following beneficial effects:

[0051] The present invention provides an auxiliary disassembly and assembly device for crane structural components. Two hydraulic push rods 31 with two fixed seats 32 are arranged between the movable seat 1 and the adjusting seat 2. A mounting bracket 4 with two fixed frames 6 is used in conjunction with two movable components 5. The length between the movable seat 1 and the adjusting seat 2 can be adjusted according to the size of the crane structural components.

[0052] Second Embodiment

[0053] Please refer to the following: Figure 5 and Figure 6 Based on the first embodiment of this application which provides an auxiliary disassembly and assembly device for crane structural components, the second embodiment of this application proposes another auxiliary disassembly and assembly device for crane structural components. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0054] Specifically, the second embodiment of this application provides an auxiliary disassembly and assembly device for crane structural components, which differs in that it further includes a movable component 8. The movable component 8 is disposed on the movable seat 1. The movable component 8 includes a rectangular rod 81, a movable sleeve 82, a connecting bracket 83, a fixing bolt 84, a stop block 85, and a movable support 86. The rectangular rod 81 is connected to the side of the movable seat 1, and the movable sleeve 82 is sleeved on the surface of the rectangular rod 81.

[0055] The connecting bracket 83 is connected between the movable sleeve 82 and the movable bracket 86, and the fixing bolt 84 is disposed between the movable sleeve 82 and the rectangular rod 81.

[0056] The stop block 85 is connected to one end of the rectangular rod 81.

[0057] When the width of the crane structural component exceeds the initial support range of the device, loosen the fixing bolt 84 between the movable sleeve 82 and the rectangular rod 81 in the movable assembly 8, and push the movable sleeve 82 along the length of the rectangular rod 81. The movable sleeve 82 drives the movable bracket 86 to move synchronously through the connecting bracket 83 until the support surface of the movable bracket 86 is aligned with the edge of the structural component. During the adjustment process, the stop block 85 at one end of the rectangular rod 81 prevents the movable sleeve 82 from falling off the rectangular rod 81.

[0058] After adjusting the movable bracket 86 to the appropriate position, tighten the fixing bolt 84 so that the end of the fixing bolt 84 is tightly pressed against the surface of the rectangular rod 81. The position of the movable sleeve 82 is fixed by friction, thereby locking the movable bracket 86, so that the crane structural components can be placed and fixed.

[0059] Multiple fixing holes adapted to the fixing bolts 84 are provided on the surface of the rectangular rod 81. The use of the rectangular rod 81 and the loose sleeve 82 facilitates the adjustment of the left and right position of the movable bracket 86 on the surface of the movable seat 1.
