A hoisting equipment used in engineering construction

Abstract

This utility model relates to a hoisting device for engineering construction. This hoisting device, by setting multiple limiting platforms and placing adjusting components between the spacing of the limiting platforms, allows for rapid adjustment of the position of the adjusting components during use, achieving balanced hoisting without requiring frequent changes to the binding positions by workers. The inclusion of a counterweight allows for adjustment of the center of gravity of the balancing beam when complete leveling cannot be achieved by adjusting the adjusting components; this adjustment, in turn, alters the center of gravity of the lifting beam to match the center of gravity of the lifted object, further enhancing the leveling effect and making the leveling process more precise, thus ensuring the safety of hoisting the object.

Description

Technical Field

[0001] This utility model relates to the field of engineering construction technology, specifically a hoisting device used in engineering construction. Background Technology

[0002] Construction hoisting equipment refers to mechanical equipment used in construction, bridge erection, equipment installation, and other engineering operations for lifting, moving, and positioning heavy objects, such as tower cranes, truck cranes, and gantry cranes. These devices typically consist of hooks, wire ropes, lifting beams (balance beams), and power systems, and are widely used in hoisting operations of large components, steel structures, prefabricated modules, and other objects.

[0003] When lifting equipment fails to effectively balance irregular objects or asymmetrically bundled loads, it can cause the lifting beam to tilt, shifting the load's center of gravity and leading to various safety hazards. A tilted load may cause uneven stress on the wire ropes, resulting in some ropes overloading and breaking, causing objects to fall or equipment damage. In existing technologies, if the load is asymmetrically bundled or the object is an irregularly shaped building material such as irregularly shaped steel, repeated adjustments to the wire rope length or re-bundling are necessary, which is time-consuming and labor-intensive. Furthermore, manual adjustment of the bundling position may lead to inaccurate leveling due to judgment errors or improper operation, potentially causing load tilting, wire rope overload, and other risks. Therefore, this paper proposes a lifting equipment for engineering construction to address these problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a hoisting device for engineering construction, which has the advantage of enabling rapid leveling and solves the problems of insufficient precision and low work efficiency caused by manual adjustment of the binding position in existing technologies.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a hoisting device for engineering construction, comprising a balance beam, wherein a central connecting platform for connecting a hoisting rope is provided in the middle of the balance beam, and end connecting platforms are provided at both ends of the balance beam; two sets of limiting groups are symmetrically arranged on the top of the balance beam, each limiting group comprising multiple limiting platforms arranged at equal intervals, and each limiting platform is provided with a locking hole for connection. The balance beam is also symmetrically provided with two adjusting components for connecting the hoisted object. Both adjusting components are set within the distance of the limiting platform. The balance beam is also symmetrically provided with two sets of balancing units for leveling it.

[0006] Furthermore, the adjusting component includes two vertical rods for support, and a horizontal rod adapted to the distance between the limiting platforms is fixedly installed on the top of the two vertical rods. The horizontal rod is set within the distance between the limiting platforms. The bottom of the two vertical rods is equipped with a lifting rod, which makes the adjusting component form a stable frame. The bottom of the vertical rods is also equipped with a rope connecting ring for connecting the binding rope of the lifted object.

[0007] Furthermore, the crossbar is also provided with steel plates that are raised in the middle and horizontal at both ends. The raised middle part is provided on the crossbar, and the horizontal parts at both ends are provided on the upper surface of the limiting platform, and are fixed to the crossbar by connecting to the locking hole.

[0008] Furthermore, the counterweight assembly includes at least one counterweight block for counterweighting. The top of the counterweight block is symmetrically and spaced apart with mounting blocks. The bottom of each mounting block is provided with a groove for easy installation on the balance beam, and the top of the mounting block is provided with a first locking bolt for locking.

[0009] Furthermore, the mounting block is also provided with a second locking bolt, and the mounting block is detachably connected to the balance beam through the second locking bolt.

[0010] Compared with the prior art, the technical solution of this application has the following beneficial effects: This hoisting equipment for engineering construction features multiple limit platforms with adjustable components positioned between them. This allows for rapid adjustment of the adjustable components' positions during use, achieving balanced hoisting without requiring frequent changes to the binding positions by workers. Furthermore, the inclusion of a counterweight allows for adjustment of the balance beam's center of gravity when the adjustable components cannot achieve complete leveling. This adjustment, in turn, alters the center of gravity of the hoisting beam to match the weight of the object being hoisted, further enhancing the leveling effect and ensuring greater precision during leveling. This, in turn, guarantees the safety of hoisting and transporting the object. Attached Figure Description

[0013] 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.

[0014] Example 1: Please see Figure 1-4 This embodiment of a hoisting device for engineering construction includes a balance beam 1. The balance beam 1 has a central connecting platform 11 for connecting the hoisting rope in the middle and end connecting platforms 12 at both ends. The top of the balance beam 1 is symmetrically provided with two sets of limiting groups 13. Each limiting group 13 includes multiple limiting platforms 131 arranged at equal intervals. Each limiting platform 131 is provided with a locking hole 132 for connection. The balance beam 1 is also symmetrically provided with two adjusting members 2 for connecting the hoisted object. The two adjusting members 2 are both arranged within the spacing of the limiting platforms 131. The balance beam 1 is also symmetrically provided with two sets of leveling units 3 for leveling it. In practical use, when workers need to hoist asymmetrical or irregular building materials, such as irregularly shaped steel structures, they can first connect corresponding hoisting ropes to the two adjusting components 2, then tie the ropes to the object to be hoisted. Workers can then lift the object once. If the balancing beam 1 tilts after hoisting, the object can be lowered, and the position of one adjusting component 2 on the end connecting platform 12 can be adjusted, along with the length of the hoisting rope on that component 2, for a second lifting. If the second lifting has achieved leveling, the object can be directly hoisted. If not leveled, the object is lowered again for a second leveling. During the second leveling, the counterweight 3 on the balancing beam 1 can be moved to shift its center of gravity, further improving leveling. Once the second leveling is complete, the object can be hoisted.

[0015] It is worth noting that the hoisting rope in this embodiment is preferably made of steel cable and is equipped with an adjustable quick-release buckle. The quick-release buckle is used by passing one end of the steel cable through the quick-release buckle, and then inserting the other end of the cable around the adjusting piece 2 and then inserting it back into the quick-release buckle from the reverse direction and locking it to complete the connection. When it is necessary to adjust the length of the hoisting rope, it can be achieved by adjusting the position of the quick-release buckle on the steel cable, thereby ensuring that it can achieve a quick leveling effect during use.

[0016] The technical effects of the above embodiments are as follows: by setting multiple limiting platforms 131 and placing the adjusting member 2 between the spacing of the limiting platforms 131, the position of the adjusting member 2 can be quickly adjusted during use, achieving a balanced lifting effect without the need for frequent changes in the binding position by the staff; by setting a counterweight 3, when it is impossible to achieve complete leveling by adjusting the adjusting member 2, the position of the counterweight 3 can be adjusted to change the center of gravity of the balance beam 1 itself, thereby adapting to the center of gravity of the lifted object, further increasing its leveling effect, making it more accurate in the leveling process, and thus ensuring the safety of lifting the object.

[0017] As a preferred technical solution in this embodiment, the adjusting component 2 includes two vertical rods 21 for support. A horizontal rod 22, matching the spacing between the limiting platforms 131, is fixedly installed at the top of the two vertical rods 21. The horizontal rod 22 is positioned within the spacing between the limiting platforms 131. A lifting rod 23 is provided at the bottom of the two vertical rods 21, forming a stable frame for the adjusting component 2. A lifting rope connecting ring 24 for connecting a lifting rope is also provided at the bottom of the vertical rods 21. This connection method allows for quick position adjustment during use when the operator needs to adjust its position. The horizontal rod 22, inserted between the two limiting platforms 131, can be removed and inserted into another gap. It is worth noting that, in actual use, the horizontal rod 22 is preferably made of rectangular steel, with a width matching the spacing between the limiting platforms 131.

[0018] As a preferred technical solution in this embodiment, the crossbar 22 is further provided with 25, which is a steel plate with a central protrusion and horizontal ends. The central protrusion is provided on the crossbar 22, and the horizontal ends are provided on the upper surface of the limiting platform 131. 25 is connected to the locking hole 132 via 26 to fix the crossbar 22. This connection method increases the firmness of the adjusting member 2 on the limiting assembly 13. After the operator adjusts the position of the crossbar 22, 25 is placed on top of it, and then 26 is used to lock it between the crossbar and the locking hole 132, thereby ensuring its fixation during hoisting.

[0019] As a preferred technical solution in this embodiment, the counterweight 3 includes at least one counterweight block 31 for counterweighting. The top of each counterweight block 31 is symmetrically and spaced apart with mounting blocks 32. The bottom of each mounting block 32 has a groove for easy installation on the balance beam 1, and its top is provided with a first locking bolt 33 for locking. The spaced mounting blocks 32 allow for effective sliding on the balance beam 1 during use, ensuring rapid leveling. The first locking bolts 33 ensure a locking effect between the counterweight and the balance beam 1, preventing slippage during lifting and thus maintaining the balance of the balance beam 1.

[0020] As a preferred technical solution in this embodiment, the mounting block 32 is further provided with a second locking bolt 34, and the mounting block 32 is detachably connected to the balance beam 1 through the second locking bolt 34. This ensures that the mounting block 32 can be quickly assembled and disassembled during use. In actual use, mounting blocks 32 of different weights can be set, and by assembling mounting blocks 32 of different weights, it can be adapted to lifting objects of different weights, achieving a precise adjustment effect.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
