Description

Technical Field

[0001] This utility model relates to the field of cable unloading technology, and more specifically, to a mobile quick-installation cable unloading device for tower cranes. Background Technology

[0002] Tower cranes are large lifting machines with tall towers and slewing booms. They are mainly used in construction sites, ports, mines, and other places to carry out vertical lifting and horizontal transport of heavy objects. With the advantage of the height of the tower and the rotation and luffing function of the boom, tower cranes can efficiently complete material hoisting within a large working radius, making them an indispensable key piece of equipment in modern engineering construction. The unloading device of the tower crane's main cable is a core component to ensure the safe operation of the cable. Its main function is to reduce or transfer the mechanical stress borne by the cable during dynamic operation, preventing wear, breakage, and electrical faults caused by long-term stress.

[0003] Existing cable unloading devices have a single function and are only suitable for fixing multiple cables. When a large tower crane uses multiple cables to power the crane, multiple independent unloading devices need to be installed, which increases equipment costs. When raising the standard section of the tower crane, all unloading devices need to be removed. After the raising is completed, the unloading devices need to be tightened again from bottom to top, which increases operational risks and construction time. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a mobile quick-installation cable unloading device for tower cranes, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a movable quick-installation cable unloading device for tower cranes, comprising an installation plate, a first clamping plate, and a second clamping plate. The front and rear sides of the first clamping plate are in contact with the second clamping plate and the installation plate, respectively. A receiving frame is fixedly connected to the rear side of the installation plate. Three U-shaped plates are fixedly connected to the bottom edge of the front side of the installation plate. An adjustment assembly is provided between the three U-shaped plates. The adjustment assembly includes a lead screw, three sliders, two sliding rods, three sleeves, a handle, a first fixing bolt, and three second fixing bolts. The front and rear ends of the lead screw are fixedly connected to one of the U-shaped plates via bearings. The front and rear ends of the two sliding rods are fixedly connected to the other two U-shaped plates, respectively. The three sliders are movably sleeved on the lead screw and the two sliding rods, and one slider is threadedly connected to the lead screw. The top ends of the three sleeves are fixedly connected to the second clamping plate.

[0006] Furthermore, the rear end of the handle is fixedly connected to the lead screw, and the handle is fixed to one of the U-shaped plates by a first fixing bolt.

[0007] As can be seen, in the above technical solution, the handle is fixed to one of the U-shaped plates by the first fixing bolt, thereby fixing the first clamping plate and the second clamping plate together.

[0008] Furthermore, the top ends of the three sliders are respectively inserted into the interior of the three sockets, and the three sliders and the three sockets are respectively fixed by three second fixing bolts.

[0009] As can be seen, the above technical solution facilitates the disassembly and replacement of the second clamping plate.

[0010] Furthermore, a suspension plate is fixedly connected to the rear side of the receiving frame, which serves to facilitate the suspension of the first and second wire clamping plates.

[0011] Furthermore, the front side of the mounting plate is fixedly connected to multiple side plates, and one side of each of the multiple side plates is in contact with the first clamping plate.

[0012] It can be seen that the above technical solution is designed to facilitate the limiting of the first and second wire clamping plates.

[0013] Furthermore, a plug is fixedly connected to the rear side of the first clamping plate, and the rear side of the plug extends into the interior of the receiving frame. The receiving frame is provided with locking bolts, and the receiving frame and the plug are fixed together by locking bolts.

[0014] Furthermore, both the first and second wire clamping plates have multiple gaskets fixedly connected inside.

[0015] As can be seen, in the above technical solution, the gasket can prevent wear caused by rigid contact between the cable, the second clamping plate, and the first clamping plate.

[0016] The technical effects and advantages of this utility model are as follows: 1. This utility model involves placing multiple cables sequentially between a first clamping plate and a second clamping plate, then rotating the handle to drive the lead screw to rotate, thereby causing the second clamping plate to contact the first clamping plate. The second clamping plate and the first clamping plate together compress and limit the multiple cables. Finally, the suspension plate is hung on the tower body of the tower crane. The operation is simple and convenient for fixing multiple cables, while improving the working efficiency of the tower crane when lifting and raising. 2. This utility model allows for the disassembly and replacement of the second clamping plate by sequentially rotating the three second fixing bolts away from the three inserts, then moving the second clamping plate upwards and moving the three inserts away from the three sliders respectively. The locking bolts are then rotated away from the inserts, and the first clamping plate is moved horizontally away from the receiving frame to disassemble and replace the first clamping plate. The structure is simple and easy to install and disassemble. Attached Figure Description

[0021] Refer to the instruction manual appendix Figure 1-4The tower crane movable quick-installation cable unloading device of this embodiment includes a mounting plate 1, a first clamping plate 2, and a second clamping plate 3. The front and rear sides of the first clamping plate 2 are in contact with the second clamping plate 3 and the mounting plate 1, respectively. A receiving frame 8 is fixedly connected to the rear side of the mounting plate 1. Three U-shaped plates 4 are fixedly connected to the bottom edge of the front side of the mounting plate 1. An adjustment assembly 5 is provided between the three U-shaped plates 4. The adjustment assembly 5 includes a lead screw 501, three sliders 502, two slide rods 503, and three... The components include a sleeve 504, a handle 505, a first fixing bolt 506, and three second fixing bolts 507. The front and rear ends of the lead screw 501 are fixedly connected to one of the U-shaped plates 4 via bearings. The front and rear ends of the two slide rods 503 are fixedly connected to the other two U-shaped plates 4 respectively. Three sliders 502 are movably sleeved on the lead screw 501 and the two slide rods 503 respectively, and one of the sliders 502 is threadedly connected to the lead screw 501. The top ends of the three sleeves 504 are fixedly connected to the second clamping plate 3.

[0022] Furthermore, the rear end of the handle 505 is fixedly connected to the lead screw 501, and the handle 505 is fixed to one of the U-shaped plates 4 by the first fixing bolt 506. The rear side of the receiving frame 8 is fixedly connected to the suspension plate 7, which serves to facilitate the suspension of the first clamping plate 2 and the second clamping plate 3.

[0023] Furthermore, the top ends of the three sliders 502 are respectively inserted into the interior of the three inserts 504, and the three sliders 502 and the three inserts 504 are respectively fixed by three second fixing bolts 507. Multiple side plates 6 are fixedly connected to the front side of the mounting plate 1, and one side of each of the multiple side plates 6 is in contact with the first clamping plate 2. An insert block 9 is fixedly connected to the rear side of the first clamping plate 2, and the rear side of the insert block 9 extends into the interior of the receiving frame 8. A locking bolt 10 is provided on the receiving frame 8, and the receiving frame 8 and the insert block 9 are fixed by the locking bolt 10.

[0024] The three second fixing bolts 507 are rotated sequentially and moved away from the three inserts 504, thereby releasing the fixation between the three sliders 502 and the three inserts 504. Then, the second clamping plate 3 is moved upward and the three inserts 504 are moved away from the three sliders 502 respectively, allowing the second clamping plate 3 to be disassembled and replaced. The locking bolt 10 is rotated and moved away from the insert 9, thereby releasing the fixation between the receiving frame 8 and the insert 9. Then, the first clamping plate 2 is moved horizontally and the insert 9 is moved away from the receiving frame 8, allowing the first clamping plate 2 to be disassembled and replaced. The structure is simple and easy to install and disassemble. Similarly, the first clamping plate 2 and the second clamping plate 3 are installed. The four side plates 6 can limit the movement of the first clamping plate 2 and the second clamping plate 3.

[0025] Furthermore, multiple gaskets are fixedly connected inside both the first wire clamping plate 2 and the second wire clamping plate 3.

[0026] The usage method of this embodiment is as follows: In use, the operator places multiple cables sequentially between the first clamping plate 2 and the second clamping plate 3. Then, turning the handle 505 causes the lead screw 501 to rotate. Since one slider 502 is threadedly connected to the lead screw 501, and the other two sliders 502 and two sliding rods 503 cooperate to restrict the rotation of the second clamping plate 3, the lead screw 501 can drive the three sliders 502, the three inserts 504, and the second clamping plate 3 to move horizontally, causing the second clamping plate 3 to contact the first clamping plate 2. The second clamping plate 3 and the first clamping plate 2 compress and limit the multiple cables, and the gasket can prevent the cables from rigidly contacting the second clamping plate 3 and the first clamping plate 2, thus preventing wear. Then, the first fixing bolt 506 fixes the handle 505 to one of the U-shaped plates 4, thereby fixing the first clamping plate 2 and the second clamping plate 3. Finally, the suspension plate 7 is hung on the tower of the tower crane. The cables are disassembled in the same way. The operation is simple and convenient for fixing multiple cables, while improving the working efficiency of the tower crane during lifting.
