Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to an adjustable rebar lifting clamp. Background Technology

[0002] Prefabricated construction and assembly construction are common methods to save construction costs. During the main construction phase, steel bars are temporarily assembled on the ground at the construction site and then hoisted to the construction location by a crane for installation.

[0003] A search revealed Chinese patent CN206842997U, which discloses a rebar cage lifting device for a crane. The device includes a horizontal lifting beam of the crane and several lifting devices. The lifting devices are located at the bottom of the horizontal lifting beam and include a first telescopic hydraulic cylinder. The fixed end of the first telescopic hydraulic cylinder is fixedly connected to the bottom of the horizontal lifting beam. The free ends of three second telescopic hydraulic cylinders are fixedly connected to the free ends of the first telescopic hydraulic cylinder. Rebar cage fixing devices are respectively installed at the free ends of the three second telescopic hydraulic cylinders. Each rebar cage fixing device includes a left connecting rod, a right connecting rod, and a third telescopic hydraulic cylinder. This device has a simple structure, is easy to operate, requires no manual operation, saves manpower, and is safe and reliable. The rebar cage fixing device can accurately and stably fix the rebar cage. Simultaneously, the trapezoidal rebar grooves of the left and right connecting rods can prevent the rebar cage from shifting during transportation, and the anti-slip layer can increase the friction between the rebar cage and the trapezoidal rebar grooves, preventing it from slipping out.

[0004] Based on the above search and existing technology, the findings were as follows:

[0005] Existing patents have fixed hydraulic strokes, making it difficult to quickly adapt to non-standard sized rebar cages; the geometry of the trapezoidal rebar groove limits the clamping of irregularly shaped rebars, and the complex structure of multiple hydraulic cylinders requires additional hydraulic power units, significantly increasing equipment purchase and maintenance costs, thus having certain limitations. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model proposes an adjustable rebar lifting clamp, which significantly reduces on-site assembly time, thereby shortening construction time; at the same time, it reduces the risk of accidents during high-altitude operations.

[0007] The technical solution to achieve the purpose of this utility model is as follows: an adjustable rebar lifting clamp, comprising multiple steel plate bodies and rebar frames, each of the steel plate bodies having an installation hole inside, and also including a pin assembly and a connection hole:

[0008] The pin assembly includes an adjustable clamp that is inserted into one side of the steel plate body;

[0009] The connection hole is located on the top of the steel plate body.

[0010] Preferably, multiple screws are threadedly installed between the main steel plates, an arc-shaped washer is fixedly installed on one side of the adjustable clamp, and a bolt is threadedly installed between the adjustable clamp and the mounting hole.

[0011] Preferably, a knob is provided on the other side of the adjustable clamp, and a clamping plate is fixedly installed at one end of the knob, with the steel bar frame being snapped into the interior of the adjustable clamp.

[0012] Compared with existing technologies, the significant advantages of this invention are:

[0013] Firstly, the adjustable clamp of this utility model can be pre-installed on the ground, which significantly reduces the safety risks of high-altitude operations, enables rapid assembly, and the modular design and threaded connection shorten on-site construction time; the knob and clamp design supports clamping of steel bars of different diameters, making it widely applicable.

[0014] Secondly, this utility model allows for flexible adjustment of the clamp size by adding or removing the main steel plate and screw; it enhances the contact area between the clamp and the reinforcing bar to prevent slippage; the layout of the connecting holes ensures even load distribution during hoisting, reducing the need for high-altitude work equipment and manpower, while the modular design reduces maintenance costs.

[0015] This invention solves the problems of existing patented hydraulic stroke being fixed, making it difficult to quickly adapt to non-standard sized rebar cages; the geometric shape of the trapezoidal rebar groove limiting the clamping of irregularly shaped rebars; and the complex structure of using multiple hydraulic cylinders requiring additional hydraulic power units, which significantly increases equipment purchase and maintenance costs.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0024] This utility model provides an adjustable rebar lifting clamp through improvements. The technical solution of this utility model is as follows:

[0025] Example 1

[0026] like Figure 1 As shown, an adjustable rebar lifting clamp includes multiple steel plate bodies 1 and rebar frames 5. Each steel plate body 1 has an installation hole 101 inside, which significantly reduces on-site assembly time and thus shortens construction time. It also includes a pin assembly 2 and a connecting hole 3.

[0027] The pin assembly 2 includes an adjustable clamp 201 that is inserted into one side of the steel plate body 1. The installation of the adjustable clamp can be completed on the ground, reducing the risk of accidents during high-altitude operations.

[0028] The connecting hole 3 is opened on the top of the steel plate body 1 to facilitate lifting and ensure the force balance during lifting.

[0029] Example 2:

[0030] Based on the adjustable rebar lifting clamp provided in the first embodiment of this application, the second embodiment of this application proposes another adjustable rebar lifting clamp. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0031] The second embodiment of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0032] like Figures 2-4 As shown, multiple screws 4 are threadedly installed between the main steel plate 1. An arc-shaped washer 202 is fixedly installed on one side of the adjustable clamp 201. A bolt 203 is threadedly installed between the adjustable clamp 201 and the mounting hole 101. The arc-shaped washer 202 is more adaptable to the shape of the steel bar, and the screws 4 are connected to the main steel plate 1, so the number of steel plates can be adjusted according to actual needs.

[0033] Furthermore, a knob 204 is provided on the other side of the adjustable clamp 201. A clamping plate 205 is fixedly installed at one end of the knob 204. The rebar frame 5 is snapped into the inside of the adjustable clamp 201. The adjustable clamp 201 can adjust its width by the knob 204 to accommodate rebars of different diameters.

[0034] The specific working method is as follows: Multiple steel plate bodies 1 are connected by screws 4 to form a stable frame structure. Each steel plate body 1 has an installation hole 101 inside for fixing the pin assembly 2 and the adjustable clamp 201. The adjustable clamp 201 is fixed to the installation hole 101 by bolts 203, and the width of the clamp plate 205 is adjusted by the knob 204 to accommodate steel bar frames 5 of different diameters. The design of the arc-shaped gasket 202 makes the clamp fit the shape of the steel bar better and enhances the clamping stability. Lifting is carried out through the connection hole 3 on the top of the steel plate body 1 to ensure force balance. The modular design of the clamp allows for pre-assembly on the ground, reducing the risk of high-altitude operations. After the steel bar frame 5 is inserted into the adjustable clamp 201, it is locked by the knob 204 to complete the fixation. According to the construction requirements, the number of steel plate bodies 1 can be increased or decreased or the length of the screws 4 can be adjusted to adapt to the lifting tasks of steel bars of different specifications. In addition, the suspension assembly can be increased or decreased according to the number of steel bar cages to improve adaptability.

[0035] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
