Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of workshop lifting tools, and particularly relates to a balance lifting tool for replacing the wind and fire wheels of a cooling bed. Background Art
[0002] A cooling bed is a working surface for effectively cooling rolled products in the metallurgical rolling industry. During the cooling process, it is also necessary to transport and move the rolled products. Therefore, wind and fire wheels need to be installed in the cooling bed. The wind and fire wheels will wear during use and need to be replaced regularly. The existing replacement of the wind and fire wheels of the cooling bed is carried out by using a crane to obliquely pull the wind and fire wheels with a steel rope and using a hoist to pull the wind and fire wheels on the opposite side, and the replacement is carried out under the cooperation of the hoist and the crane.
[0003] However, the existing replacement method has the phenomenon of non-standard lifting with oblique pulling, and requires the cooperation of multiple people. The time for working at high altitude and near the edge is relatively long during the replacement process. Therefore, when the crane is used for translation and position adjustment during the replacement process, the steel rope used for oblique pulling and the hook head of the crane are prone to squeezing and injuring people under the action of force. Therefore, the replacement efficiency of the wind and fire wheels of the cooling bed is relatively low and the risk is relatively high. Content of the Utility Model
[0004] The purpose of the utility model is to provide a balance lifting tool for replacing the wind and fire wheels of a cooling bed to solve the problems of relatively low replacement efficiency and relatively high risk for the replacement of the wind and fire wheels of the cooling bed.
[0005] The utility model specifically adopts the following technical solutions to achieve the above purpose:
[0006] A balance lifting tool for replacing the wind and fire wheels of a cooling bed includes a lifting beam. A lifting ring is connected to the outside of the lifting beam in a limited sliding manner. A crane hook is arranged above the lifting ring. A steel wire rope is wound between the crane hook and the lifting ring. The end of the steel wire rope is fixedly clamped with a rope buckle on the outside of the bottom. A hanging chain is wound between the crane hook and the top of the right side of the lifting beam. A hoist is fixedly connected to the middle of the hanging chain. A lifting lug is fixedly installed at the bottom end on the left side of the crane hook. A shackle is fixedly installed at the bottom end on the right side of the crane hook. A placement sleeve is fixedly installed at the bottom end of the shackle. A counterweight block is placed inside the placement sleeve.
[0007] Further, threaded rods are connected to the middle parts of the front and rear sides of the lifting ring. The threaded rods penetrate through the front and rear side walls of the lifting ring. A knob is fixedly installed at the end of the threaded rod away from the lifting beam. A toothed block is connected to the end of the threaded rod close to the lifting beam in a limited rotating manner.
[0008] Further, tooth grooves are formed in the side walls of the front and rear sides of the lifting beam. The lifting ring is located outside the position where the tooth grooves are formed on the lifting beam, and the tooth grooves are adapted to the toothed blocks. The cooperation of the tooth grooves and the toothed blocks is used to limit the lifting ring.
[0009] Furthermore, the overhead crane hook is fixedly suspended below the overhead crane in the workshop, and the overhead crane is used to drive the overhead crane hook to move.
[0010] Furthermore, after the steel wire rope bypasses downward from the overhead crane hook, both ends bypass from one side of the lifting ring, then bend upward, and are fixed near the port side at the overlapping part by a rope buckle. The working length of the steel wire rope can be adjusted by disassembling and assembling the rope buckle.
[0011] Furthermore, the load-bearing capacity of the hoist is two tons.
[0012] Furthermore, the counterweight blocks in the placement sleeve can be increased or decreased to change the weight of the counterweight.
[0013] The beneficial effects of the present utility model are as follows:
[0014] 1. In the present utility model, through the design of the hanging beam, in cooperation with the hoisting of the steel wire rope and the hanging chain, and the cooperation of the counterweight blocks, the lever principle can be used to hoist and replace the wind fire wheels. The position can be adjusted on one side of the counterweight block, and there is no need to work at the high edge for a long time during the replacement process, which is safer, reduces the operation risk of replacement. At the same time, the position adjustment operation of the wind fire wheels is more convenient, there is no need for oblique pulling, which conforms to the hoisting regulations, and there is no need for multiple people to cooperate, and the operation is more convenient, improving the replacement efficiency.
[0015] 2. In the present utility model, by adjusting the position of the lifting ring and the weight of the counterweight, the acting moment of the hanging beam can be adjusted to be applicable to the replacement of wind fire wheels with different weights and different installation positions, improving the practicability of the balance hoist for replacing the wind fire wheels of the cooling bed.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.
[0025] A balance sling for replacing the hot wheels of a cooling bed according to a preferred embodiment of the present utility model will be elaborated in detail below, as Figures 1-7 shown, a balance sling for replacing the hot wheels of a cooling bed includes a lifting beam 1. A lifting ring 2 is connected to the outside of the lifting beam 1 in a limited sliding manner. An overhead crane hook 3 is provided above the lifting ring 2. The overhead crane hook 3 is fixedly suspended below the overhead crane in the workshop, and the overhead crane is used to drive the overhead crane hook 3 to move.
[0026] A steel wire rope 4 is wound between the overhead crane hook 3 and the lifting ring 2. A rope buckle 5 is fixedly clamped to the outside of the end of the steel wire rope 4. After the steel wire rope 4 bypasses downward from the overhead crane hook 3, both ends bypass from one side of the lifting ring 2, and then bend upward, and are fixed near the port side at the overlapping part by the rope buckle 5. The working length of the steel wire rope 4 can be adjusted by disassembling and assembling the rope buckle 5. A hanging chain 6 is wound between the overhead crane hook 3 and the top of the right side of the lifting beam 1. A hoist 7 is fixedly connected to the middle of the hanging chain 6. The load-bearing capacity of the hoist 7 is two tons. A lifting lug 8 is fixedly installed at the bottom end of the left side of the overhead crane hook 3. The lifting lug 8 is used for hoisting the hot wheels.
[0027] A shackle 9 is fixedly installed at the bottom end of the right side of the overhead crane hook 3. A placing sleeve 10 is fixedly installed at the bottom end of the shackle 9. A counterweight 11 is placed inside the placing sleeve 10. The counterweight 11 inside the placing sleeve 10 can be increased or decreased to change the weight of the counterweight.
[0028] Threaded rods 12 are threadedly connected to the middle parts of the front and rear sides of the lifting ring 2. The threaded rods 12 penetrate through the front and rear side walls of the lifting ring 2. A knob 13 is fixedly installed at the end of the threaded rod 12 far from the lifting beam 1. A tooth block 14 is connected to the end of the threaded rod 12 close to the lifting beam 1 in a limited rotational manner. Tooth grooves 15 are provided on the side walls of the front and rear sides of the lifting beam 1. The lifting ring 2 is located outside the position where the tooth grooves 15 are provided on the lifting beam 1, and the tooth grooves 15 are adapted to the tooth blocks 14, and the lifting ring 2 is limited by the cooperation of the tooth grooves 15 and the tooth blocks 14.
[0029] The working principle of the utility model is:
[0030] During the lifting process, the steel wire rope 4 and the hanging chain 6 are used in conjunction with the overhead crane hook 3 to realize the lifting of the hanging beam 1, and then the lifting lug 8 is used to lift the hot wheels that need to be replaced, and the overhead crane is started to drive the overhead crane hook 3 to lift the hot wheels and move and adjust them. During the movement, the operator can push the hanging beam 1 to rotate on one side of the counterweight block 11, and then adjust the position of the lifted hot wheels to move the hot wheels to the replacement location. There is no need to work at a high place near the edge for a long time during the replacement process, which reduces the work risk.
[0031] By pulling the hoist 7 and changing the effective length of the hanging chain 6, the height at which the wind and fire wheels are lifted by the lifting ear 8 can be fine-tuned to facilitate installation. Through the action of the hanging beam 1, when the overhead crane cannot drive the overhead crane hook 3 to move above the replacement position, there is no need to obliquely pull the wind and fire wheels to move the wind and fire wheels for replacement, which is more in line with the lifting regulations, does not require the cooperation of multiple people, is more convenient to operate, and improves the replacement efficiency.
[0032] According to the different gravity of the hoisted wind and fire wheels, the counterweight can be adjusted by adding or reducing the counterweight block 11. At the same time, the tooth block 14 can be used in cooperation with the tooth grooves 15 on both sides of the suspension beam 1 to drive the rotation of the threaded rod 12 through the knob 13. When the threaded rod 12 is threadedly connected to the lifting ring 2, and the threaded rod 12 is limited and rotated, the tooth block 14 can be disengaged from the tooth groove 15, so that the position of the lifting ring 2 on the periphery of the suspension beam 1 can be adjusted. At the same time, the effect of the rope buckle 5 can be used to adaptively adjust the effective length of the wire rope 4. After the adjustment is completed, the knob 13 is rotated in the opposite direction to make the tooth block 14 engage with the tooth groove 15 to fix the position of the lifting ring 2. Therefore, according to the different gravity of the wind and fire wheels and the different distances between the lifting position and the extreme position of the overhead crane hook 3, the acting torque of the suspension beam 1 can be adjusted to adapt to wind and fire wheels of different weights and different installation positions.
[0033] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
