Description

Technical Field

[0001] This utility model relates to a device suitable for hoisting various types of beams. Background Technology

[0002] Existing lifting equipment for bridge beams mainly includes wire ropes, hooks, and slings. Wire ropes, composed of multiple strands of twisted steel wires, possess high tensile strength, capable of bearing the weight of the bridge beam. They can be bent and twisted to adapt to lifting requirements of different shapes and angles. During lifting, the wire rope resists wear when in contact with other objects, extending its service life. Hooks, consisting of a hook body, hook shank, and anti-derailment device, are easy to manufacture and use, capable of bearing significant weight, and suitable for lifting heavy bridge beams. They can be quickly connected to wire ropes, chains, etc., facilitating lifting operations. Slings include chains, slings, and clamps. Appropriate slings can be selected according to different lifting needs, adapting to bridge beams of different shapes and sizes, reducing damage to the beam. Some slings have anti-slip and anti-derailment functions, improving the safety of lifting operations.

[0003] The drawback of existing technology is the lack of a versatile lifting tool that can distribute lifting force and protect the beam structure. Summary of the Invention

Each upper lifting plate has at least one first wire rope hole near its two ends, and each lower support plate has at least one second wire rope hole near its two ends. The corresponding upper lifting plates and lower support plates are connected by two wire ropes. Each wire rope passes through the first wire rope hole and the second wire rope hole on the same side. The crossbeam has a lifting ring in the middle.

[0006] Optionally, multiple first wire rope holes are provided at intervals near both ends of the upper lifting plate, and multiple second wire rope holes are provided at intervals near both ends of the lower support plate.

The top surface of the upper hanging plate has a threaded hole corresponding to the connecting hole. The upper hanging plate and the slot are fixed together by connecting bolts passing through the connecting hole and the threaded hole.

[0008] Optionally, a plurality of upper hanging plates are fixed in the slots near both ends of the crossbeam, and each upper hanging plate corresponds to a lower support plate connected by the wire rope.

It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

In the description of the present invention, it should be noted that unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium; it can refer to the internal connection of two components.

[0016] like Figure 1 As shown, this utility model provides a device suitable for hoisting various beams, including a crossbeam 1, two sets of upper lifting plates 2, and lower support plates 3 corresponding to the upper lifting plates 2. The two upper lifting plates 2 are symmetrically fixed on the crossbeam 1. Multiple first wire rope holes 2-1 are provided at intervals near both ends of the upper lifting plates 2. Multiple second wire rope holes 3-1 are provided at intervals near both ends of the lower support plates 3. The upper lifting plates 2 and the lower support plates 3 are connected by two wire ropes. Each wire rope passes through the first wire rope hole 2-1 and the second wire rope hole 3-1 on the same side. The crossbeam 1 has a lifting ring 1-3 in the middle.

[0017] The aforementioned structure, consisting of a crossbeam 1, two sets of upper lifting plates 2, and a lower support plate 3, resembles a carrying pole. It is made of high-strength steel. The length of the crossbeam 1 is determined based on the width of the beam being lifted and the lifting requirements; generally, it must be able to span the beam and leave sufficient lifting space. The lifting rings 1-3 on the crossbeam 1 are used to connect the wire ropes or hooks of the lifting equipment. By adjusting the binding positions of the two ends of the wire ropes, this device can be adapted to lift beams of different specifications.

[0018] Multiple slots 1-1 are spaced apart at both ends of the bottom of the crossbeam 1. The top of each slot 1-1 has a connecting hole 1-2, into which the top of the upper lifting plate 2 can extend. The top surface of the upper lifting plate 2 has threaded holes corresponding to the connecting holes 1-2. The upper lifting plate 2 is fixed to the slots 1-1 by connecting bolts 4 passing through the connecting holes 1-2 and the threaded holes. The design of multiple slots 1-1 allows for adjustment of the spacing between the two upper lifting plates 2. The number of upper lifting plates 2 and lower support plates 3 can also be increased according to the length of the beam. For longer beams, increasing the number of upper lifting plates 2 and lower support plates 3 increases the stress points on the beam, disperses the lifting force, and further increases the versatility of the device.

[0019] Two binding rings 1-4 are symmetrically arranged on both sides of the crossbeam 1. The two binding rings 1-4 can be connected to the first wire rope hole 2-1 on the upper lifting plate 2 on the same side by wire rope, and the wire rope is pulled in, so as to further distribute the lifting force on the crossbeam 1.

[0020] like Figure 2 As shown, a middle upper hanging plate 5 is fixed at the bottom center of the crossbeam 1. The middle upper hanging plate 5 corresponds to a middle lower support plate 6. The structure of the middle upper hanging plate 5 is the same as that of the upper hanging plate 1, and the structure of the middle lower support plate 6 is the same as that of the lower support plate 3. The middle upper hanging plate 5 and the middle lower support plate 6 are set to increase the number of intermediate hanging points.

[0021] The advantages of the above structure are:

[0022] 1. Uniform force distribution

[0023] (1) Distribute lifting force

[0024] When hoisting bridge beams, the spreader-beam structure can evenly distribute the concentrated lifting force of the hoisting equipment (such as a crane) across multiple lifting points on the beam. This prevents the beam from cracking, deforming, or even breaking due to excessive localized stress. For example, when hoisting large concrete box girders, the spreader-beam structure distributes the lifting force evenly to the lifting points at both ends and the middle of the box girder, making the stress on the entire beam more reasonable during the hoisting process.

[0025] (2) Protect the beam structure

[0026] For bridge beams with complex internal structures or made of special materials, uniform stress distribution is particularly important. It can reduce stress concentration within the beam, protect critical structural components such as reinforcing bars and prestressed steel strands, and ensure the integrity and safety of the beam during hoisting.

[0027] 2. Increase stability

[0028] (1) Prevent beam swaying

[0029] The use of a spreader-beam structure can increase the stability of bridge beams during hoisting. Because the spreader beam typically has a certain length and rigidity, it can balance and stabilize the beam during lifting, reducing swaying and swing. This is especially crucial for hoisting operations in confined spaces or at heights, reducing construction risks and improving operational safety.

[0030] (2) Facilitates adjustment of beam posture

[0031] During the hoisting process, the posture of the bridge beam can be easily adjusted by changing the length or lifting height of different lifting points on the spreader beam structure, ensuring its accurate installation in the predetermined position. For example, when the beam needs to be placed horizontally, the height of each lifting point on the spreader beam can be finely adjusted to keep the beam level.

[0032] 3. Adaptable to different beam sizes and shapes

[0033] (1) Adjustability

[0034] The length, width, and lifting point positions of a spreader-beam structure can typically be adjusted according to the size and shape of different bridge beams. This makes the spreader-beam structure lifting system highly versatile, capable of adapting to various types of beams, including concrete beams and steel beams of different lengths, widths, and heights. For example, for longer beams, a longer spreader-beam structure can be used, and the number of lifting points can be increased to ensure stability during the lifting process.

[0035] (2) Flexibility

[0036] For some irregularly shaped beams, such as curved beams and inclined beams, the spreader pole can be specially designed and installed to lift these special-shaped beams. For example, when lifting curved beams, the spreader pole can be designed to be curved according to the curvature of the beam, so that the lifting point can better fit the surface of the beam, ensuring the stability and safety of the lifting.

[0037] 4. Improve construction efficiency

[0038] (1) Quick installation and disassembly

[0039] Carrying pole type hoisting systems are typically simple in structure, and easy and quick to install and dismantle. On the construction site, the carrying pole can be quickly connected to the lifting equipment and the beam for hoisting operations. After hoisting, the carrying pole can also be quickly dismantled, saving time for the next step. This is of great significance for accelerating bridge construction progress and improving construction efficiency.

[0040] (2) Reduce equipment investment

[0041] (3) Because the spreader pole structure can adapt to the hoisting of beams of different sizes and shapes, the construction unit does not need to equip each type of beam with special hoisting equipment, thereby reducing equipment investment costs. At the same time, the reusability of the spreader pole also reduces construction costs and improves resource utilization.

[0042] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made in accordance with the claims of this utility model should still fall within the patent coverage of this utility model.
