Description

Technical Field

[0001] This utility model relates to the technical field of tower crane accessories, specifically to a modular counterweight block for a tower crane. Background Technology

[0002] Tower cranes are large-scale mechanical equipment commonly used in construction. Counterweights are an important component of tower cranes, used to balance the overturning moment generated when the boom lifts heavy objects, thus ensuring the stable operation of the tower crane.

[0003] Traditional tower crane counterweights are usually cast or poured as a single piece, which has the following disadvantages:

[0004] 1. Inconvenient transportation: The integral counterweight is large in size and weight, occupies a lot of space during transportation, and has high requirements for the load capacity and size of the transport vehicle, resulting in high transportation costs and poor flexibility.

[0005] 2. Installation difficulties: Due to its large weight, it requires large lifting equipment for hoisting and installation, which increases the difficulty of installation and construction costs, and also places high demands on the working conditions of the construction site.

[0006] 3. Poor versatility: Different models and specifications of tower cranes require different weights and sizes of counterweights. Integral counterweights are difficult to adjust and combine flexibly according to actual needs, resulting in low versatility. Utility Model Content

[0007] In view of the problems existing in the above-mentioned tower cranes, this utility model is proposed.

[0008] Therefore, the purpose of this utility model is to provide a modular counterweight for tower cranes, which solves the problems of inconvenient transportation, difficult installation, and poor versatility.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A modular counterweight for a tower crane includes a unit block. Two connecting blocks are fixedly provided on one side of the unit block. Two fixing grooves are fixedly provided on one side of the unit block. The fixing grooves and connecting blocks are slidably engaged. A first bolt is threaded on one side of the connecting block. Two unit blocks are fixedly connected by the first bolt. A frame is provided on the outside of the unit block. Multiple second bolts are threaded on the outer wall of the frame. The unit block is fixed in the frame by the second bolts.

[0011] Preferably, the top of the unit block is welded with multiple lifting lugs, and the multiple lifting lugs are U-shaped.

[0012] Preferably, a weight label is fixedly provided on the surface of the unit block, and the weight label is a laser-printed label.

[0013] Preferably, the connecting block is a trapezoidal block and the fixing groove is a trapezoidal groove.

[0014] Furthermore, the lifting lugs are made of high-strength steel.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] This utility model uses connecting blocks and fixing grooves for splicing, making the device easy to transport: by disassembling the integral counterweight block into multiple unit counterweight blocks, the volume and weight of individual components are greatly reduced, making it easy to transport. Ordinary transport vehicles can be used for transportation, improving the flexibility of transportation and reducing transportation costs.

[0017] This invention is easy to install: the unit counterweight is lightweight, requiring relatively small lifting equipment, thus reducing installation difficulty and construction costs. Furthermore, the modular design makes the installation process more flexible, allowing for gradual installation based on the actual conditions of the construction site.

[0018] This utility model is highly versatile: by combining unit counterweights of different quantities and specifications, it can meet the counterweight requirements of different models and specifications of tower cranes, improve the versatility of counterweights, and reduce the need to customize different counterweights due to different tower crane models.

[0019] This invention is easy to maintain: if a certain unit counterweight is damaged, only that unit counterweight needs to be replaced, without having to replace the entire counterweight, thus reducing maintenance costs and time. Attached Figure Description

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model discloses a modular counterweight for a tower crane.

[0028] This utility model provides, for example Figure 1-3 The tower crane's modular counterweight block, as shown, includes a unit block 1. Two connecting blocks 2 are fixedly mounted on one side of the unit block 1. Two fixing slots 3 are also fixedly opened on one side of the unit block 1, allowing for sliding engagement between the fixing slots 3 and the connecting blocks 2. A first bolt 4 is threaded onto one side of the connecting block 2, and the two unit blocks 1 are fixedly connected by the first bolt 4. A frame 5 is mounted on the outer side of the unit block 1, and multiple second bolts 6 are threaded onto the outer wall of the frame 5. The unit blocks 1 are fixed within the frame 5 by the second bolts 6. At the construction site, the required number of unit blocks 1 are assembled according to the tower crane's counterweight requirements. First, the connecting block 2 is aligned with the fixing slot 3 of another unit block 1 and slowly inserted to complete the initial assembly. Then, the uniformity of the splicing gap between adjacent unit blocks is checked; if any deviation is found, appropriate adjustments are made. Finally, the first connecting bolt 4 is passed through the connecting block 2, and the first bolt 4 and the second bolts 6 are tightened to securely connect the adjacent unit blocks 1.

[0029] To facilitate lifting the counterweight, such as Figure 1-3 As shown, multiple lifting lugs 7 are welded to the top of unit block 1. The multiple lifting lugs 7 are U-shaped to facilitate the lifting of the counterweight block.

[0030] To improve the versatility of unit block 1, such as Figure 1-2 As shown, a weight label 8 is fixedly provided on the surface of unit block 1. The weight label 8 is a laser-printed label, which can meet the counterweight requirements of different models and specifications of tower cranes and improve the versatility of unit block 1.

[0031] For greater stability, such as Figure 1-2 As shown, the connecting block 2 is a trapezoidal block, and the fixing groove 3 is a trapezoidal groove, for higher stability.

[0032] Finally, to prevent the lug 7 from falling off, such as Figure 3 As shown, the lifting lug 7 is made of high-strength steel to prevent it from falling off.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
