Description

Technical Field

[0001] This utility model relates to the technical field of lifting brackets for rolling mills, specifically a lifting bracket for rolling mills. Background Technology

[0002] A rolling mill is a piece of equipment used to perform the metal rolling process;

[0003] It mainly consists of rolls, roll bearings, frame, roll adjustment device, guide device, etc.

[0004] Its working principle is to apply pressure to the metal billet through the rollers, causing it to undergo plastic deformation, thereby changing the shape, size and properties of the metal, and rolling the steel billet or steel ingot into steel products of various required specifications, such as steel plates, steel strips, structural steel, steel pipes, etc.

[0005] Rolling mills play a vital role in the steel industry, directly affecting steel quality, production efficiency, and cost. With continuous technological development, rolling mills are constantly evolving and improving to adapt to higher production requirements and market demands.

[0006] Patent publication number CN213802707U discloses a lifting bracket for a rolling mill, including a bracket base, a lifting mechanism, a support plate, a guide plate, a conveyor belt, and a spacing adjustment device. Two sets of lifting mechanisms are symmetrically arranged on both sides of the upper end of the bracket base. The lifting mechanisms are connected to the support plate, and a guide plate is set on the support plate. A conveyor belt is set inside the guide plate, and a spacing adjustment device is set on one side of the conveyor belt. The rotation of the motor drives the small worm gear to rotate, and the small worm gear drives the lead screw to rotate through the large worm gear. The rotation of the lead screw causes the sliding sleeve to move, and the sliding sleeve drives the slider to move. Under the action of the slider and the sliding groove, the support plate moves vertically upward, realizing the raising of the height of the guide plate. According to the actual situation, the height of the guide plate can be changed through the lifting mechanism, so that the device can be connected with equipment of different heights, thereby improving the practicality of the device.

[0007] The existing technical solutions described above have the following drawbacks: When transferring formed steel, the formed steel is placed on a placement rack and clamped and fixed using a clamping plate. Then, a motor drives a screw to rotate, and the screw drives the placement rack to rise and fall. When clamping the formed steel, due to the different heights of the formed steel, the clamping plate may be too low. The part that exceeds the height will cause the formed steel to shake or even fall, which brings inconvenience to the lifting and transfer of the formed steel and increases the limitations of clamping the formed steel. Utility Model Content

[0008] To address the problems mentioned in the background art, the purpose of this utility model is to provide a lifting bracket for a rolling mill, which has the advantage of easy clamping. This solves the problem that when transferring formed steel, the formed steel is placed on a placement frame and clamped in place using clamping plates. A motor drives a screw to rotate, which in turn moves the placement frame up and down. However, when clamping the formed steel, due to varying heights, the clamping plate may be too low, causing the excess steel to wobble or even fall, hindering the lifting and transfer of the formed steel and increasing the limitations of the clamping method.

[0009] To achieve the above objectives, this utility model provides the following technical solution: a lifting bracket for a rolling mill, comprising a base plate, a motor fixedly connected to the top of the base plate, a lifting screw fixedly connected to the outside of the motor via a bevel gear, a fixing frame movably connected to the outside of the lifting screw, the bottom of the fixing frame fixedly connected to the top of the base plate, a placement frame threadedly connected to the surface of the lifting screw, a clamping plate provided on the inner side of the top of the placement frame, an adjusting bolt fixedly connected to the outside of the clamping plate, a fixing groove provided on the outside of the clamping plate, a sliding groove provided on the top of the clamping plate, an extension component provided on the top of the clamping plate, and a fixing mechanism provided on the outside of the clamping plate.

[0010] As a preferred embodiment of this utility model, the extended component includes an extended card plate, a slider is fixedly connected to the bottom of the extended card plate, and a card slot is provided on the bottom of the outer side of the extended card plate.

[0011] In a preferred embodiment of this utility model, the fixing mechanism includes an L-shaped fixing plate and a locking block. The top of the locking block is fixedly connected to the top of the inner side of the L-shaped fixing plate. The L-shaped fixing plate has a movable groove inside, and a fixing screw is provided inside the movable groove. The inner side of the fixing screw is fixedly connected to the inner side of the fixing groove. A textured washer is movably fitted on the surface of the fixing screw, and a hexagonal fixing nut is provided on the outer side of the textured washer. The hexagonal fixing nut is threadedly connected to the surface of the fixing screw. The outer side of the locking block contacts the inner side of the locking groove.

[0012] As a preferred embodiment of this invention, a friction pad is fixedly installed on the surface of the card block, and the outer side of the friction pad contacts the inner side of the card slot.

[0013] As a preferred embodiment of this utility model, a rubber pad is fixedly installed on the inner side of the extended card plate, and the inner side of the rubber pad is in contact with the outer side of the formed steel.

[0014] As a preferred embodiment of this utility model, a reinforcing plate is fixedly connected to the bottom of the outer side of the extended clamping plate, and the bottom of the inner side of the reinforcing plate is fixedly connected to the top of the outer side of the clamping plate.

[0015] As a preferred embodiment of this utility model, a reinforcing plate is fixedly connected to the bottom of the outer side of the fixing frame, and the bottom of the reinforcing plate is fixedly connected to the top of the base plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model, when raising the clamping plate, involves sliding an extended clamping plate with a fixed slider along a sliding groove on the top of the clamping plate to the corresponding position, then flipping the L-shaped fixing plate upwards. The L-shaped fixing plate drives the clamping block to flip upwards. When the L-shaped fixing plate and the clamping block flip upwards to the outside of the groove, they are pushed inwards. When the L-shaped fixing plate and the clamping block move into the groove, they are pressed downwards. When the clamping block engages inside the groove, the hexagonal fixing nut is rotated. The hexagonal fixing nut drives the textured washer to rotate inwards and fix it. When the textured washer rotates to contact the outside of the L-shaped fixing plate, the L-shaped fixing plate is tightened and the extended clamping plate is fixed. This allows for clamping and fixing of forming steel of different heights, thus providing the advantage of easy clamping. Through the combined use of the extended component and the fixing mechanism, the clamping plate can be quickly raised and fixed, and there are no limitations on clamping the forming steel.

[0018] 2. By setting an extension component, the clamping plate of this utility model can be lengthened, which effectively avoids the shaking of the formed steel caused by the clamping plate being too low, effectively improves the clamping and fixing effect of the formed steel, and makes it convenient for users to use.

Then, the motor drives the screw to rotate, and the screw drives the placement frame to rise and fall. However, when clamping the formed steel, due to the different heights of the formed steel, the clamping plate may be too low, and the part exceeding the height will cause the formed steel to shake or even fall, which brings inconvenience to the lifting and transfer of the formed steel and increases the limitations of the clamping of the formed steel.
