Description
Technical Field
The utility model relates to a overhead hoist of object specifically belongs to a overhead hoist for universal mill adjustment pneumatic cylinder.
Background
The universal mill adjusting hydraulic cylinder (hereinafter referred to as adjusting cylinder) is arranged on a mill housing, and the mill is a device with strong comprehensiveness and relates to the specialties of machinery, hydraulic pressure, electricity and the like, so that a plurality of related devices are arranged on a mill body.
At present, the adjusting cylinder of the universal rolling mill is large in weight and limited in installation position, and in the process of dismantling and installing the adjusting cylinder, due to the fact that a large number of devices are arranged on a mill housing, the adjusting cylinder cannot be successfully hoisted by a crane at one time, at the moment, the adjusting cylinder needs to be dragged by a guide chain for people, in the process of matching the guide chain with the crane, the adjusting cylinder is easy to cause collision damage to people and surrounding devices, the working efficiency is greatly reduced, and the adjusting cylinder can be installed in place in at least 6 hours under general conditions. Therefore, the adjusting cylinder is lifted to the position to be replaced through the crane in the installation process, consumed manpower and material resources are large, the time for replacing the adjusting cylinder is long, the danger is large in the replacement process, and safety risks exist.
After retrieval: the C-shaped lifting appliance with the automatic balancing function cancels the weight box of the original C-shaped lifting appliance and is additionally provided with the adjusting sleeve. In the hoisting process, the counter-acting force can ensure that the hanger hook is balanced in a load state through the adjusting sleeve, so that the hanger can keep balance in different states without a weight box. The C-shaped hook is an improvement on the weight box, but is not suitable for hoisting an adjusting cylinder of a universal rolling mill because a hydraulic cylinder groove-shaped placer is not arranged.
The novel horizontal C-shaped hook changes the original horizontal C-shaped hook into a split type, and the balance weight, the hook body, the guard plate, the handrail and the arc plate are unchanged, so that the lifting lug is removed and changed into a structure consisting of a pinion, a speed reduction motor, a lifting shaft, a lifting seat, an electric control box and a rotary support. The improved horizontal coil C-shaped hook can rotate automatically without manual operation, so that the collision damage of the horizontal coil can be reduced, and the working strength of workers is reduced. A rotating device is additionally arranged on the horizontal coil C-shaped hook, but a hydraulic cylinder groove-shaped placer is not arranged, so that the horizontal coil C-shaped hook is not suitable for hoisting an adjusting cylinder of a universal rolling mill.
The C-shaped cross beam lifting appliance comprises a head cross beam, a middle inverted Y-shaped structure, a bottom inserting leg structure, a locking device and a positioning device. The head cross beam structure is composed of a head cross beam and a head cross beam lifting lug, the head cross beam lifting lug and the lifting hook are connected through a chain block, and the lengths of chain blocks in different directions are adjusted to control the installation levelness of the hoisting assembly. The Y-shaped structure can meet the requirement that the long part freely moves at the Y-shaped opening, and the gravity center of the hoisting assembly can be ensured to be in a reasonable position. The locking device fixes the hoisting assembly on the fork leg to ensure that the hoisting assembly cannot fall off in the hoisting and mounting processes. And after the hoisting assembly reaches the installation position, limiting the swinging of the hoisting tool and the hoisting assembly by using a positioning device. And after the installation activity is completed, the locking device and the positioning device are removed. The horizontal coil C-shaped hook is greatly improved in structure, but is not suitable for lifting an adjusting cylinder of a universal rolling mill because a hydraulic cylinder groove-shaped placer is not arranged.
