Abstract

The utility model discloses a ring rolls core roller hoist device, including the core roller the handling bolt on core roller upper portion, its characterized in that: the device comprises a support, wherein a group of lifting chains are arranged above the support, the lower part of the lifting chains is connected with a support base, the support base is U-shaped, and a U-shaped step through hole is formed in the center of the support base and matched with a lifting bolt. The device needs to be used with a traveling crane in a matching way, and has the following advantages: 1. the operation is simple, and the working efficiency is improved; 2. the high-altitude operation of workers is not needed, and the risk of falling from the high altitude is avoided.

Description

Ring rolls core roller hoist device

Technical Field

The utility model belongs to the technical field of ring rolls core roller hoist and mount maintenance technique and specifically relates to a ring rolls core roller hoist device is related to.

Background

The core roller is a necessary die in the process of rolling the ring piece by the ring rolling mill, and the core roller and the main roller cooperate to control the radial size of the ring piece to meet the process requirements. The core roller is easy to wear and even break in a high-temperature and high-pressure working environment, and a workshop is required to stop production and halt to overhaul equipment and replace the core roller after the core roller breaks down. Generally, in the maintenance process, the core roller needs to be disassembled and assembled by means of simple tools such as a travelling crane, a lifting ring and a steel wire rope, the core roller is vertically installed in an equipment rack, during the disassembling and assembling, the hoisting process needs workers to slowly take out or put in the core roller from the rack by using the travelling crane, when the core roller of the ring rolling machine with small specification is hoisted, the operation is simple and convenient, but when the core roller with large specification is hoisted (the length of the core roller is more than 3.5 meters), the workers are required to carry out high-altitude operation (the lifting ring or the steel wire rope is manually fixed at the upper end part of the core roller), the high-altitude falling danger exists during the work, and the operation difficulty. And the core roller is difficult to keep balance when the steel wire rope is adopted for hoisting, so that the dismounting process takes a long time, and the overhauling progress of the whole equipment is influenced. This is a disadvantage of the prior art.

Disclosure of Invention

The utility model aims to overcome the shortcoming that exists among the prior art, provide an overweight large-scale ring hoisting device under the condition of current driving a vehicle, make large-scale ring operation convenient and fast, operation process safety, the technical scheme of adoption is: the utility model provides a ring rolls core roller hoist device, including the core roller the handling bolt on core roller upper portion, its characterized in that: the device comprises a support, wherein a group of lifting chains are arranged above the support, the lower part of the lifting chains is connected with a support base, the support base is U-shaped, and a U-shaped step through hole is formed in the center of the support base and matched with a lifting bolt.

The technical characteristics of the utility model are also: the edges of the U-shaped step through holes need to be chamfered.

The technical characteristics of the utility model are also: the two sets of the hanging chains are symmetrically arranged and movably connected with the through hole on the bracket, and the other end of the hanging chain is provided with a hanging ring.

The beneficial effect of this scheme can be known according to the statement to above-mentioned scheme, and the device needs to use with the driving cooperation, has following advantage: 1. the core roller is convenient and quick to assemble and disassemble, and the overhaul period is shortened; 2. the stability is good, when the support is used, only workers need to assist to keep the support base sleeved on the bolt head above the core roller, and the operation is simple; 3. the safety is higher, and compared with the conventional hoisting by adopting a steel wire, the hoisting by the device is more stable and safer; 4. the danger of workers working aloft is avoided.

Drawings

FIG. 1 is the structure diagram of the present invention, wherein 1-chain, 2-bracket, 3-bracket base, 4-lifting bolt, 5-core roller, 6-U-shaped step through hole, 7-hanging ring.

Detailed Description

The following describes embodiments of the present invention with reference to the drawings. The utility model discloses a ring rolls core roller hoist device, including core roller 5 handling bolt 4 on 5 upper portions of core roller, the device include support 2, set up a set of chain sling 1 in the top of support 2, and its below links to each other with support frame 3, and support frame 3 is the U type, and its center is provided with U type step through-hole 6 to cooperate with handling bolt 4.

The edges of the U-shaped step through holes 6 need to be chamfered.

Two sets of the hanging chains 1 are symmetrically arranged and movably connected with the through hole on the bracket 2, and the other end of the hanging chains is provided with a hanging ring 7.

The use steps are as follows:

1. placing two lifting chains 1 with hanging rings 7 on a travelling crane anchor hook;

2. lifting the crane to enable the lifting chain 1 to be unfolded and lift the support 2;

3. moving the bracket 2 to the position above the core roller 5, and moving the travelling crane to clamp the hoisting bolt 4 into the bracket seat 3;

4. the crane is slightly lifted for a certain distance, the hoisting bolt 4 on the core roller 5 is in contact with the bracket base 3 to bear force, the crane is kept still for one minute, and hoisting work is carried out after the core roller 5 is in a vertical stable state.

Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and the changes, modifications, additions or replacements made by those skilled in the art within the scope of the present invention also belong to the protection scope of the present invention.
