Description

TECHNICAL FIELD

[0001] The utility model belongs to metallurgy field relates to the connecting structure of the quick dismounting of slab rotary clamp. BACKGROUND

[0002] The connecting reliability of the clamp and the crane directly influences the operation efficiency of the production line. The current industry generally adopts a fixed connecting structure, which is specifically shown as follows: the pulley assembly is directly welded to the surface of the clamp square box beam through the side guard plate to form an integral frame which cannot be disassembled. The structure exposes significant defects in long-term use: when the clamp needs to be replaced due to mechanical wear, deformation or drive system failure, the operator must systematically disassemble the four groups of pulley steel wires, including loosening the tension device, separating the pulley assembly, and releasing the fixed end of the steel wire, and other complicated procedures. The whole replacement process takes more than 2 hours, which seriously affects the continuous production rhythm of the production line.

[0003] Through field practice analysis, the traditional fixed connection mainly has three technical bottlenecks: first, the welding structure of the pulley assembly and the square box beam causes the modular replacement to be blocked. During the operation process, the gas cutting equipment needs to be used to break the original welding point, which not only pollutes the working environment with a large amount of metal debris, but also needs to be surface polished after the removal to meet the flatness requirement of the new clamp installation; second, the disassembly process of the steel wire needs to be operated by multiple people. The operator needs to climb to the high-altitude operation of the crane beam, which has the risk of falling, and the surface lubricating oil of the scattered steel wire easily penetrates into the ground, forming an oil stain belt which is difficult to clean, which not only violates the enterprise environmental management standard, but also has the risk of slipping. Third, the fixed structure lacks a quick positioning device. When the new clamp is installed, the cooperation gap of the pulley assembly and the steel wire needs to be adjusted repeatedly, which consumes a lot of time in the calibration process, directly affecting the fault recovery efficiency of the production line. The above technical defects have become a common problem restricting the rapid maintenance of the equipment of the metallurgical enterprise, and the modular transformation of the key connecting device needs to be realized through structural innovation. UTILITY MODEL CONTENTS

[0004] Therefore, the utility model aims at providing a connecting structure for quick dismounting of a slab rotary clamp, solving the problem of quick dismounting and replacement of the 4-pulley fixed slab rotary clamp, improving the work efficiency, reducing the labor intensity, and shortening the clamp replacement time.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a connecting structure for quick dismounting of a slab rotary clamp, including a base arranged on a clamp square box beam, a pulley being installed on the base through a connecting pin shaft and a pulley side guard plate; the upper end of the pulley side guard plate is connected with a pulley, and the lower end is installed on the base through a connecting pin shaft and a pin shaft isolation sleeve.

[0006] Optionally, the base is provided with four, respectively through the fixed bolt installation in the clamp square box girder 4 corners.

[0007] Optionally, the connecting pin shaft is provided with a retreat stop plate, and the retreat stop plate is installed between the pulley side guard and the connecting pin shaft through a positioning bolt, so as to prevent the axial movement of the connecting pin shaft.

[0008] Optionally, the retreat stop plate is located at the end of the connecting pin shaft and abuts against the outside of the pulley side guard; the pulley side guard is provided with two symmetrical plates, respectively located on both sides of the pulley.

[0009] Optionally, the pin shaft isolation sleeve is sleeved on the connecting pin shaft and located between the pulley side guard and the base.

[0010] Optionally, each base is fixed on the clamp square box girder by a plurality of fixed bolts, and the fixed bolts are uniformly distributed along the circumference of the base.

[0011] Optionally, the edge of the base and the upper surface of the clamp square box girder are reinforced by continuous welding, and the welding part covers the four edges of the base.

[0012] The beneficial effects of the utility model lie in:

[0013] 1. Revolutionary improvement of maintenance efficiency: the pin shaft connection system of the base and the pulley side guard makes the clamp replacement process completely avoid the traditional welding removal process. The operator only needs to disassemble the fixed bolt and the connecting pin shaft, and the clamp can be lifted off as a whole. Combined with the quick unlocking design of the retreat stop plate, the total replacement time is compressed from 2 hours to 10 minutes, which is 12 times more efficient than the traditional process, significantly reducing the loss of production line downtime.

[0014] 2. Great optimization of manual operation intensity: through the preinstalled connection structure of the pulley block and the square box girder, the dangerous procedures such as steel wire rope disassembly and high-altitude positioning adjustment are completely eliminated. The operator only needs to complete the bolt fixation of the base and the pin shaft assembly on the ground, reducing 75% of the high-altitude operation links, and the manpower demand for single replacement operation is reduced from 4 people to 2 people.

[0015] 3. Environmental protection and operation safety are improved simultaneously: since the whole process does not need to contact the steel wire rope assembly, the risk of lubricating oil leakage is fundamentally eliminated, and the penetration pollution of about 200L of oil stains to the workshop floor is eliminated every year. At the same time, the double anti-falling mechanism formed by the pin shaft isolation sleeve and the retreat stop plate effectively avoids the safety hazards such as tool falling and part slipping in the traditional steel wire rope disassembly process.

[0016] 4. The structural stability is significantly enhanced: the circumferential continuous welding process of the base four corners makes the bearing capacity of the connecting structure increase to 1.8 times of the traditional welded pulley, and no displacement cracking phenomenon of the base occurs after 20,000 times of fatigue test.
