Abstract
Description
Technical Field
[0001] This utility model relates to the field of hoisting equipment technology, and in particular to a modular hoisting tool. Background Technology
[0002] Modular hoisting improves construction efficiency by prefabricating modules in a factory and assembling them quickly on-site. Furthermore, modular design and construction effectively reduce material waste and construction time, thereby lowering overall project costs. Since installation modules are typically manufactured centrally in the workshop, more stringent quality control can be implemented during modular prefabrication, ensuring that each module meets standards and specifications, thus improving the overall quality of the final project. Because modular construction can be carried out in a controlled environment, the risks of construction in adverse weather conditions are significantly reduced, and the safety of the construction process is enhanced. At the same time, on-site hoisting operations are relatively simple, improving worker safety. Modular construction reduces on-site work time, lowers operating costs, and reduces the risks of working at heights. However, with the increasing scale and complexity of projects, traditional single-component hoisting devices often cannot meet the demands for time and safety performance; therefore, there is an urgent need for an efficient and safe modular hoisting tool. Utility Model Content
[0003] The purpose of this utility model is to provide a modular hoisting tool that can improve hoisting efficiency, ensure quality, reduce safety hazards during construction operations, save installation costs, has a simple structure, is easy to operate, and is highly practical.
[0004] The present invention adopts the following technical solution:
[0005] A modular lifting tool includes a main hook, which is connected to a primary load-bearing beam via a main lifting rope. Multiple secondary load-bearing beams are provided at the bottom of the primary load-bearing beam via auxiliary lifting ropes. The multiple secondary load-bearing beams are arranged at intervals along the length of the primary load-bearing beam, and each secondary load-bearing beam is provided with a lifting rope at its bottom.
[0006] Preferably, the support on which the main hook is located is equipped with a movable pulley.
[0007] Preferably, lifting lugs are provided at both ends of the primary load-bearing beam, and at both ends of the top and bottom of the secondary load-bearing beam. The main lifting rope is connected to the lifting lugs on the primary load-bearing beam; the auxiliary lifting rope is connected to the lifting lugs on the upper part of the secondary load-bearing beam; and the lifting lugs at the bottom of the secondary load-bearing beam are connected to the lifting rope.
[0008] Preferably, the main lifting rope is connected to the corresponding lifting lug via a secondary hook; the auxiliary lifting rope and the hoisting rope are both connected to the corresponding lifting lug via auxiliary hooks.
[0009] Preferably, the lifting lug is a plate-type lifting lug.
[0010] Preferably, the force-bearing points of the plate-type lifting lug, the corresponding secondary hook, and the corresponding auxiliary hook are all located on the same axis.
[0011] Preferably, the bottom of the primary load-bearing beam is provided with multiple load-bearing blocks at intervals, and a secondary load-bearing beam parallel to the primary load-bearing beam is inserted through the load-bearing blocks. The auxiliary lifting rope is set on the secondary load-bearing beam by a tightening device.
[0012] Preferably, the secondary load-bearing beam has an H-shaped and arc-shaped cross-section; the load-bearing block has an installation groove that matches the shape of the secondary load-bearing beam.
[0013] Preferably, the fastening device includes a sleeve fitted on the secondary load-bearing beam, and a fastening screw is provided at the bottom of the sleeve; the sleeve has an arc-shaped transition hole for the auxiliary lifting rope to pass through.
[0014] Preferably, both the primary load-bearing beam and the secondary load-bearing beam are H-shaped steel beams.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting multiple secondary load-bearing beams at intervals at the bottom of the primary load-bearing beam, this utility model can form a two-level load-bearing beam hoisting structure. When connecting the hoisted integrated structure, there will be more load-bearing points, thereby forming an extremely stable hoisting structure and ensuring the safety of hoisting. At the same time, the overall hoisting also effectively improves hoisting efficiency, reduces construction time, and thus achieves the goal of reducing the overall project cost.

[0019] The present invention will now be described clearly and completely with reference to the accompanying drawings and embodiments:
[0020] like Figures 1 to 3As shown, the modular lifting tool of this utility model includes a main hook 1. The main hook 1 is connected to a primary load-bearing beam 3 via a main lifting rope 2. Multiple secondary load-bearing beams 5 are arranged at intervals along the length of the primary load-bearing beam 3 via auxiliary lifting ropes 4 at the bottom of the primary load-bearing beam 3. Each secondary load-bearing beam 5 is perpendicular to the primary load-bearing beam 3. A lifting rope 6 is provided at the bottom of each secondary load-bearing beam 5. The lifting rope 6 includes a lifting rope 6 and a lifting hook 7 at the bottom end of the lifting rope 6. (See reference...) Figure 1 and Figure 2 As shown, the two-stage load-bearing structure formed by the primary load-bearing beam 3 and the secondary load-bearing beam 5 provides more load-bearing points when connecting to the integrated structure being hoisted at the bottom. This results in a highly stable hoisting structure, effectively ensuring the safety of the hoisting process. Compared to traditional single-component hoisting, this method reduces the time workers spend working at heights, thus lowering the risks associated with such work. Furthermore, utilizing a ground-assembly hoisting scheme effectively saves installation costs while ensuring the quality of assembly. In this embodiment, both the primary load-bearing beam 3 and the secondary load-bearing beam 5 are H-shaped steel beams. Using H-shaped steel beams significantly improves the beam's load-bearing capacity while saving on materials.
[0021] Furthermore, a movable pulley 8 is installed on the support where the main hook 1 is located. According to the force analysis and the core mechanical equilibrium equation 2F=G, the resultant force of the two ropes (or the tension F on both sides) is equal to the weight G of the suspended object. Each hook lock connecting the movable pulley 8 is subjected to only 1 / 2G of force. One of the lifting ropes is fixed, while the other is driven by a motor to realize the lifting process. This motor only needs a force greater than F=1 / 2G to drive the lifting and lowering of the heavy object. Therefore, the upper limit of the overall weight of the integrated structure being lifted can be greatly increased.
[0022] In addition, lifting lugs 9 are provided at both ends of the primary load-bearing beam 3, and at both ends of the top and bottom of the secondary load-bearing beam 5. The main lifting rope 2 is connected to the lifting lugs 9 on the primary load-bearing beam 3 through the secondary hook 10; the auxiliary lifting rope 4 is connected to the lifting lugs 9 on the upper part of the secondary load-bearing beam 5 through the auxiliary hook 11; and the lifting rope 6 is connected to the lifting lugs 9 on the lower part of the secondary load-bearing beam 5 through the auxiliary hook 11 set at the top of the lifting rope 6.
[0023] In this embodiment, the lifting lug 9 is a plate-type lifting lug. Plate-type lifting lugs have a larger connection area, ensuring stronger connection strength. The plate-type lifting lug is connected to the corresponding load-bearing beam by welding. Furthermore, the stress points of the plate-type lifting lug on the primary load-bearing beam and its corresponding secondary hook 10, and the plate-type lifting lug on the secondary load-bearing beam and its corresponding auxiliary hook 11, are all located on the same axis. This reduces the risk of hook disengagement and ensures more uniform stress distribution on the bottom weld of the plate-type lifting lug, preventing one end from cracking due to excessive stress on one side of the weld.
[0024] Furthermore, multiple load-bearing blocks 12 are spaced apart at the bottom of the primary load-bearing beam 3. A secondary load-bearing beam 13, parallel to the primary load-bearing beam 3, passes through each load-bearing block 12. An auxiliary lifting rope 4 is mounted on the secondary load-bearing beam 13 via a tightening device. This tightening device can be adjusted along the length of the secondary load-bearing beam 13, allowing for lifting operations of various sizes of integrated structures, greatly increasing its flexibility and expanding its applicability. Preferably, the secondary load-bearing beam 13 has an H-shaped cross-section with a circular arc to ensure structural strength and reduce wear on the auxiliary lifting rope 4 during operation. The load-bearing blocks 12 have mounting grooves that match the shape of the secondary load-bearing beam 13.
[0025] In this embodiment, the fastening device includes a sleeve 14 fitted onto the secondary load-bearing beam 13. The sleeve 14 has protruding blocks that match the grooves on both sides of the secondary load-bearing beam 13. The protrusions slide within the grooves. A fastening screw 15 is provided at the bottom of the sleeve 14. By rotating the fastening screw 15, it abuts against the secondary load-bearing beam 13, thereby positioning the sleeve 14. An arc-shaped transition hole 16 is provided on the sleeve 14 for the auxiliary lifting rope 4 to pass through. The transition hole 16 is opened at the top of the sleeve 14 and extends along its side wall. The top of the sleeve 14 matches the arc-shaped structure at the top of the secondary load-bearing beam 13 to reduce wear between the auxiliary lifting rope 4 and the auxiliary lifting rope 4 during insertion, thereby extending the service life of the auxiliary lifting rope 4.
