Problems solved by technology

[0003] 1. The operation is difficult. After the steel wire rope passes through the cylinder, it is difficult for the lifting personnel to hang the steel wire rope into a higher hook because the diameter of the cylinder is too large, so it is necessary to use a climbing vehicle to work;
[0004] 2. The safety risk is high.

Embodiment Construction

[0028] see Figure 1-Figure 8 , This embodiment provides a self-locking lifting device for a large cylinder, including a spreader body 1 , an anti-loosening rod 2 , a pressure rod 3 , a lever 4 , a front connecting assembly 5 , a rear connecting assembly 6 , and a middle connecting assembly 7 . In the non-working state, under the action of gravity and leverage, the anti-off bar 2 with the counterweight 204 is at the lowest position, and the pressure bar 3 is at the highest position and protrudes from the lower arm 102 of the spreader body 1 . When the cylinder body is hoisted, the pressure rod 3 is pressed down, and the anti-loosening rod 2 is raised by the action of the lever 4 to realize the lifting self-locking function. The status of the cylinder lifting operation.

[0029] Such as figure 2 As shown, the upper arm 101 and the lower arm 102 on the spreader body 1 are connected by a single-sided connecting arm 107 to form a C-shaped opening 106, which can be lifted throug...

Abstract

The invention relates to a large barrel self-locking lifting device and a lifting method. The large barrel self-locking lifting device comprises a lifting appliance body, an anti-disengaging rod, a pressing rod, a lever, a front connecting assembly, a rear connecting assembly and a middle connecting assembly. The lifting appliance body can be lifted by a crane and other lifting equipment, the anti-disengaging rod is installed at the end of the C-shaped opening, the pressing rod is installed in the middle of the lifting appliance body, and the lever is installed at the bottom of the lifting appliance body. The anti-disengaging rod is connected with the lever through a front connecting assembly, the pressing rod is connected with the lever through a rear connecting assembly, and the lever is connected with the lifting appliance body through a middle connecting assembly. The C-shaped lifting appliance is adopted, large cylindrical parts can be lifted conveniently, lifting self-locking is achieved through the lever, and lifting safety is guaranteed. The device has the characteristics of convenience in operation and high safety.

Description

technical field [0001] The invention belongs to the technical field of hoisting equipment, and in particular relates to a large cylinder self-locking hoisting device and a hoisting method. Background technique [0002] A large cylinder has a diameter of about 5 meters after roll bending. After roll bending, the cylinder is placed horizontally on the roll bending equipment. The existing lifting method is to pass the steel wire rope through the cylinder, and the two ends of the steel wire rope are hung on the hoist. There is no special lifting device for lifting on the equipment hook. Existing hoisting method has following shortcoming: [0003] 1. The operation is difficult. After the steel wire rope passes through the cylinder, it is difficult for the lifting personnel to hang the steel wire rope into a higher hook because the diameter of the cylinder is too large, so it is necessary to use a climbing vehicle to work; [0004] 2. The safety risk is high, and the lifting per...
