Description

Technical Field

[0001] This utility model belongs to the technical field of gas cylinder hoisting equipment, specifically a clamping device for hoisting gas cylinders. Background Technology

[0002] During routine inspection and maintenance within the factory area, gas cylinders often require short-distance movement via handling and hoisting, primarily moving them back and forth between the loading / unloading point and the maintenance work location. Currently, manufacturers typically install a hydraulic balancer between these two locations as the power source for lifting and moving the cylinders. This hydraulic balancer, along with cylinder mounting brackets and other devices, lifts and moves the cylinders. However, after placing the cylinder in the mounting bracket, the fixing clamps inside the bracket must be tightened to secure the cylinder before lifting and moving it. Once at the destination, the fixing clamps must be loosened to lower the cylinder, resulting in cumbersome operation and low work efficiency. Therefore, there is a need to design a gas cylinder lifting clamping device that can replace the cylinder mounting bracket and works in conjunction with the hydraulic balancer, and is easier to operate. Utility Model Content

[0003] To address the above technical problems, this utility model provides a gas cylinder hoisting clamping device that can replace the gas cylinder fixing frame and is easy to operate when used in conjunction with a hydraulic balance crane, thus solving the problem of low work efficiency caused by the cumbersome operation of existing clamping devices.

[0004] To solve the above technical problems, the technical solution of this utility model is as follows: a clamping device for lifting gas cylinders, including a connecting plate, a lifting chain, and a clamping assembly. The clamping assembly includes a first clamping ring and a second clamping ring, both of which are elliptical rings. The first clamping ring is sleeved inside the second clamping ring, and the overall assembly is X-shaped. The two outer sides of the first clamping ring are rotatably connected to the two inner sides of the second clamping ring. The upper side of both the first and second clamping rings is fixedly connected to a lifting hole. Each lifting hole is fixedly connected to one end of a lifting chain, and the other ends of both lifting chains are fixedly connected to the lower end of the connecting plate.

[0005] Furthermore, the inner sides of both the first and second clamping rings are covered with a non-slip rubber layer.

[0006] Furthermore, pin holes are provided at the rotatable connection positions of the first clamping ring and the second clamping ring, and pins are respectively provided in the two pin holes located on the same side. The first clamping ring and the second clamping ring are rotatably connected to the pins.

[0007] Furthermore, the lifting chain is any one of galvanized iron chain, stainless steel chain, or synthetic fiber strap.

[0008] This utility model has the following advantages compared with the prior art:

[0009] 1. This utility model uses a clamping assembly consisting of a first clamping ring and a second clamping ring. When lifting a gas cylinder, the weight of the clamping assembly causes the upper sides of the first and second clamping rings to move closer together, automatically clamping the gas cylinder and securing it. After lowering the gas cylinder, the upper sides of the first and second clamping rings move away from each other, releasing the gas cylinder. During this process, the operator only needs to perform two operations: placing the clamping assembly on the gas cylinder before lifting and removing the clamping assembly after lifting. Compared to the traditional method of placing, tightening, loosening, and removing the gas cylinder, this utility model simplifies the operation and improves the efficiency of gas cylinder lifting and transfer.

[0010] 2. This utility model improves the friction when the device clamps the gas cylinder by wrapping an anti-slip rubber layer around the inner sides of the first and second clamping rings, thereby enhancing the stability of the clamping. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] like Figures 1 to 2 The device shown is a clamping device for lifting gas cylinders, including a connecting plate 1, a lifting chain 2, and a clamping assembly. The clamping assembly includes a first clamping ring 3 and a second clamping ring 4, both of which are elliptical rings. The first clamping ring 3 and the second clamping ring 4 are both made of rigid materials to prevent deformation when clamping the gas cylinder. The first clamping ring 3 is sleeved inside the second clamping ring 4 and the overall assembly is X-shaped. The two outer sides of the first clamping ring 3 are rotatably connected to the two inner sides of the second clamping ring 4. The upper side of the first clamping ring 3 and the second clamping ring 4 are both fixedly connected to a lifting hole 5. Each lifting hole 5 is fixedly connected to one end of a lifting chain 2. The other ends of the two lifting chains 2 are fixedly connected to the lower end of the connecting plate 1. The upper end of the connecting plate 1 can be fixedly connected to a lifting lug for quick connection with the lifting end of a hydraulic balance crane.

[0016] To increase the friction between the clamping assembly and the outside of the gas cylinder, and to increase the stability of clamping the gas cylinder, the inner sides of the first clamping ring 3 and the second clamping ring 4 are both covered with a non-slip rubber layer.

[0017] In order to achieve a rotatable connection between the first clamping ring 3 and the second clamping ring 4, pin holes are provided at the rotatable connection positions of the first clamping ring 3 and the second clamping ring 4. Pins 6 are respectively provided in the two pin holes on the same side, and the first clamping ring 3 and the second clamping ring 4 are rotatably connected to the pins 6.

[0018] To facilitate the connection of the clamping assembly and the connecting plate 1, the lifting chain 2 is made of any one of galvanized iron chain, stainless steel chain, or synthetic fiber strap. In this embodiment, the lifting chain 2 is made of galvanized iron chain.

[0019] The specific working process of this utility model is as follows:

[0020] First, fix the upper end of the connecting plate 1 of this device to the lifting end of the hydraulic balance crane. Then, operate the hydraulic balance crane to move this device above the gas cylinder that needs to be lifted and transferred. Lower the lifting end of the hydraulic balance crane, causing the clamping components of this device to gradually move downwards towards the gas cylinder. Under the action of gravity, the operator will separate the lower ends of the first clamping ring 3 and the second clamping ring 4, which are vertically attached together, to both sides, and pass the gas cylinder cap at the top of the gas cylinder through the two clamping rings until the top of the gas cylinder enters the rings of the first clamping ring 3 and the second clamping ring 4. Continue to lower the lifting end of the hydraulic balance crane. When the first clamping ring 3 and the second clamping ring 4 move downwards to avoid the bottleneck at the top of the gas cylinder and are located in the upper middle part of the gas cylinder, stop lowering the lifting end of the hydraulic balance crane. The lifting end of the hydraulic balance crane is raised, causing the connecting plate 1 to rise. The first clamping ring 3 and the second clamping ring 4 are pulled up through the lifting chain 2 and the lifting hole 5. Under the weight of the clamping assembly, the horizontal angle between the first clamping ring 3 and the second clamping ring 4 increases, and the two lifting holes 5 move closer to each other until the first clamping ring 3 and the second clamping ring 4 clamp the gas cylinder and lift it up. Then, the hydraulic balance crane is controlled to move the device holding the gas cylinder to another position. The lifting end of the hydraulic balance crane is controlled to slowly lower until the bottom of the gas cylinder touches the ground. After that, it is lowered a certain distance. The operator lifts the lower sides of the first clamping ring 3 and the second clamping ring 4 and removes the clamping assembly from the gas cylinder, completing the lifting and moving of the gas cylinder.
