Description

Technical Field

[0001] This utility model relates to the field of hoisting technology, specifically a hoisting device for steel plate installation. Background Technology

[0002] Steel plates, as an important building and industrial material, have a wide range of applications, covering multiple industries such as construction, manufacturing, and energy. In construction, installation work often requires lifting. Whether using binding or clamping, lifting operations are unstable or the lifting angle may not meet construction requirements, posing significant safety hazards. Steel plates are also highly susceptible to deformation during lifting, which is extremely detrimental to construction, installation, and processing. To ensure the safety of steel plate lifting, eliminate safety hazards during lifting, and meet the requirements for steel plate lifting and installation under complex working conditions, this utility model provides a lifting device for steel plate installation.

[0008] A clamping pin is inserted into a horizontal through hole, and the head end of the clamping pin has an insertion hole.

[0009] The pin-lock is U-shaped, and the second side of the pin-lock is L-shaped. The second back of the pin-lock is located on the first side of the U-shaped ring, and the second side of the pin-lock is inserted into the socket on the second side of the U-shaped ring.

[0029] Please refer to the attached document. Figures 1-4 This application illustrates a lifting device for steel plate installation, which is used to stably lift steel plates during steel plate hoisting and installation in the construction engineering field, making it easier for operators to efficiently complete the installation work. Specifically, it includes: a clamp body 1, a U-shaped lifting ring 4, a clamp pin 2, and a pin limit lock 3.

[0030] The clamp body 1 is generally U-shaped, with a clamping opening 1a formed on the inner side. A horizontal through hole 1b is provided on the side plate of the clamp body 1. The width of the clamping opening 1a is slightly larger than the thickness of the steel plate to be lifted. A connecting lug 1c is fixedly provided on the top of the clamp body 1. A U-shaped lifting ring 4 is rotatably installed with the connecting lug 1c by screws. The U-shaped lifting ring 4 is installed together with the rope end of the crane. The clamp pin 2 is inserted into the horizontal through hole 1b and also passes through the steel plate to be lifted, realizing the installation of the steel plate to be lifted. A insertion hole 2a is provided at the head end of the clamp pin 2. The pin limit lock 3 is U-shaped and the pin limit lock The second side 302 of the 3 is L-shaped. The second back 301 of the pin limit lock 3 is located on the first side of the U-shaped lifting ring 4. The second side 302 of the pin limit lock 3 is inserted into the insertion hole 2a on the second side of the U-shaped lifting ring 4. The pin limit lock 3 is used to restrict the sliding of the clamp pin 2 out of the horizontal through hole 1b. Its own position (the second back 301 of the pin limit lock 3 is located on the first side of the U-shaped lifting ring 4, and the second side 302 of the pin limit lock 3 is inserted into the insertion hole 2a on the second side of the U-shaped lifting ring 4) is designed to prevent the pin limit lock 3 from slipping off, so as to ensure the stability and safety of the lifting process.

[0031] When using it, according to the position of the horizontal through hole 1b on the side plate of the clamp body 1, a lifting hole is made at the corresponding position on the steel plate to be lifted. Then, the clamping port 1a of the clamp body 1 is clamped on the steel plate to be lifted, and the clamp pin 2 is passed through the horizontal through hole 1b and the lifting hole to realize the installation of the steel plate to be lifted and the clamp body 1. Then, slide the pin limit lock 3 downward so that the bottom end of the pin limit lock 3 is inserted into the second side insertion hole 2a of the U-shaped lifting ring 4 to form a stable installation structure. Then, the clamp body 1 and the steel plate to be lifted are moved by the crane.

[0032] In practical use, multiple lifting devices can be combined together based on the horizontal length of the steel plate (generally used for vertical installation of steel plates), thereby further ensuring the stability of the steel plate being lifted.

[0033] In one embodiment, in order to further improve the stability of the lifting device during the steel plate hoisting process, two horizontal through holes 1b are provided, and the clamp pin 2 is U-shaped. The two first sides 202 of the clamp pin 2 correspond to the two horizontal through holes 1b. This method can also limit the position of the first side 202, so that the insertion hole 2a on the first side 202 always faces upward, thereby facilitating the installation of the pin limit lock 3.

[0034] In one embodiment, the two horizontal through holes 1b are located on the same horizontal plane, and the two first side portions 202 of the clamp pin 2 are also on the horizontal plane, ensuring that the insertion holes 2a on the first side portions 202 always face upward, thereby facilitating the installation of the pin limit lock 3.

[0035] In one embodiment, a locking member 5 is fixedly connected to the second back 301 of the pin limiting lock 3, and a first gap is provided between the first back 201 of the clamp pin 2 and the clamp body 1, and the bottom end of the locking member 5 engages with the first gap to lock.

[0036] like Figure 3 As shown, the user pushes the pin limit lock 3 downwards, so that the bottom end of the pin limit lock 3 is first inserted into the socket 2a. Then, the user continues to press the pin limit lock 3 down, and the pin limit lock 3 drives the locking component 5 to move downwards together. The bottom end of the locking component 5 passes through the first back 201 of the clamp pin 2 and there is a first gap between it and the clamp body 1, forming a stable lock, thereby restricting the pin limit lock 3 from moving upwards and ensuring that the pin limit lock 3 will not detach or fall off during the hoisting process.

[0037] In one embodiment, a locking block 5b is fixedly connected to the bottom end of the locking member 5. The bottom of the locking block 5b is provided with a guide bevel 5a. The guide bevel 5a can be directly inserted into the first gap between the first back 201 of the clamp pin 2 and the clamp body 1. When the user pushes down forcefully, the first back 201 of the clamp pin 2 moves, and the second side 302 of the pin limit lock 3 deforms, thereby causing the locking block 5b to cross the first gap between the first back 201 of the clamp pin 2 and the clamp body 1.

[0038] In one embodiment, an elastic block 1d is fixedly connected to the inner top of the clamp body 1. The design of the elastic block 1d can prevent the end of the steel plate from hitting the inner top of the clamping opening 1a during the installation of the steel plate.
