Description

Technical Field

[0001] This utility model relates to the field of inspection and maintenance technology of metal material surface treatment equipment, specifically to a positioning bracket for quick disassembly and assembly of furnace doors in galvanized aluminum-magnesium production lines. Background Technology

[0002] In modern industrial production, the furnace area, as one of the process sections of the galvanized aluminum-magnesium production line, has a significant impact on product performance. If a malfunction occurs in the furnace area of ​​the galvanized aluminum-magnesium production line, the furnace door needs to be disassembled and reassembled during emergency repairs. Since the sealing performance between the furnace door and the furnace body depends on the tight fit of the sealing strip or refractory cotton, these sealing components are usually relatively soft and require high installation precision. Therefore, during the disassembly and reassembly process, it is necessary to ensure that the furnace door moves horizontally to avoid interference between components. Traditional furnace door disassembly and reassembly is done manually, requiring several people to work together to lift and move the furnace door out. This is labor-intensive and can easily cause damage to the furnace door and the furnace body due to collisions. To address the aforementioned issues, utility model patent CN202422852390.7 discloses "An Industrial Boiler Door Disassembly and Assembly Device," comprising a support portion, a main rod movably disposed at one end of the support portion, and a moving mechanism disposed at the other end of the support portion. One end of the main rod is an operating end, and the other end is an execution end. The operating end is moved with the connection point between the main rod and the support portion as a fulcrum, and the execution end moves in the opposite direction along with the operating end. The execution end is equipped with a clamping mechanism, which includes multiple hooks and a positioning part. The hooks at the execution end of the main rod hook onto the handle of the target boiler door. By pressing the operating end of the main rod, the execution end of the main rod is lifted upwards. As the execution end of the main rod is lifted, the hooks simultaneously lift the boiler door. During the lifting process, the positioning part holds the boiler door in place. Once the boiler door is stable, the main rod can be pulled outwards. The moving mechanism, through the support portion, drives the main rod and the boiler door to move stably, facilitating the handling of the boiler door during disassembly and assembly.

[0003] Although the aforementioned utility model patent solves the problems of high labor intensity and easy bumps during manual handling, it requires repeated manual fine-tuning during use, making it difficult to guarantee accuracy, increasing operational risks, and has narrow scene adaptability, making it unsuitable for operation in narrow spaces. Utility Model Content

[0004] The purpose of this invention is to provide a positioning bracket for quick assembly and disassembly of furnace doors in galvanized aluminum-magnesium production lines, so as to solve the problems of low adjustment accuracy and large size of existing support devices, which are not suitable for narrow operating spaces.

[0005] To achieve the above objectives, the basic solution provided by this utility model is as follows: a positioning bracket for quick disassembly and assembly of furnace doors in a galvanized aluminum-magnesium production line, comprising a climbing pole jack, a movable base, and a support assembly. The climbing pole jack includes an anti-sinking pad, a climbing pole fixedly connected to the dustproof pad, and two movable self-locking components sleeved on the climbing pole. A handle is bolted between the two self-locking components. The movable base is bolted to the anti-sinking pad of the climbing pole jack. The support assembly is sleeved on the top of the climbing pole, and the lower end of the support assembly contacts the self-locking component located on the upper part of the climbing pole.

[0006] The principle and beneficial effects of this utility model are as follows: First, an anti-sinking pad is fixed to the bottom of the climbing pole, and then the anti-sinking pad is bolted to the movable base. Next, two self-locking components are sequentially sleeved on the climbing pole, and then the handle is bolted between the two self-locking components. Finally, the support component is sleeved on the climbing pole, with the lower end of the support component abutting against the upper end of the upper self-locking component. By pressing the handle, the two self-locking components are moved, thereby driving the movement of the support component. This adapts to the support requirements of furnace doors of different heights and is convenient for operation in relatively narrow spaces.

[0007] Option 2, which is a preferred option of the basic option, includes a triangular frame, with a load-bearing plate fixed to the upper part of the triangular frame and a pulley bolted to the lower part. The pulley is a universal wheel with a self-locking function. The triangular frame structure is stable and can avoid shaking during movement. The universal wheel with a self-locking function can reduce the labor intensity of the operator.

[0008] Option 3, which is a preferred option of the basic option, includes a square tube 1, a limiting plate fixed to the upper part of the square tube 1, a support plate 1 fixed to the limiting plate, a support plate 2 hinged to the support plate 1, the length of the support plate 2 being greater than the length of the support plate 1, one end of a rib fixed to the lower part of the support plate 1, and the other end of the rib fixed to the square tube 1. The hinged connection between the support plate 1 and the support plate 2 facilitates storage, and the rib fixed to the lower part of the support plate 1 can effectively enhance the supporting force of the support plate 1.

[0009] Option 4, which is a preferred option of the basic option, is that the climbing pole is made of square tubing and has four reinforcing ribs at the connection between the climbing pole and the anti-sinking pad, which improves the safety and durability of the climbing pole.

[0010] Option 5, which is a preferred option of the basic option, has multiple positioning holes along the center line of the climbing pole, which facilitates the self-locking component to achieve self-locking at different positions of the climbing pole.

[0011] Option 6, a preferred embodiment of Option 5, includes a square tube 2, an equilateral angle steel, a beveled cylindrical pin, and a spring. A locking hole of the same size as the positioning hole is formed at the center of the square tube 2. One side of the equilateral angle steel is fixed to the square tube 2, and the other side has a through hole. The beveled cylindrical pin can pass through the through hole, the locking hole, and the positioning hole in sequence. The spring is sleeved on the outside of the beveled cylindrical pin and is located between the square tube 2 and the equilateral angle steel. The spring's elasticity presses the beveled cylindrical pin tightly into the positioning hole, firmly locking the square tube 2 and the climbing rod, preventing relative movement. The operation is simple and the structure is stable.

[0012] Option 7, which is a preferred embodiment of Option 6, is provided with a movable pin on the inclined cylindrical pin. The pin is located on the outside of the equilateral angle steel. The pin can limit the movement range of the inclined cylindrical pin in the through hole, prevent it from dislodging from the positioning hole due to excessive movement during use, and ensure that the locking function of the self-locking component remains effective.

[0013] Option 8, a preferred embodiment of Option 7, features symmetrical baffles at the through-hole of the equilateral angle steel. The distance between the baffles matches the size of the pin. The baffles prevent the inclined cylindrical pin from coming out of the through-hole upwards or downwards under force, ensuring that the self-locking assembly can function continuously and stably. Even under large external impacts or vibrations, the baffles can limit the displacement of the inclined cylindrical pin, ensuring the locking state of the connection and improving the reliability and safety of the entire structure.

[0014] Option 9, a preferred embodiment of Option 6, involves two self-locking components fitted onto the climbing pole. Two nuts are fixed to the lower left side of the square tube 2 of the upper self-locking component, and two nuts are fixed to the upper right side of the square tube 2 of the lower self-locking component. A double-hole connecting plate 1 is bolted to each nut 1, and a double-hole connecting plate 2 is bolted to each nut 2. The double-hole connecting plates 1 and 2 are connected to the square tube 2 of the upper and lower self-locking components respectively by bolts, making the entire structure more balanced under stress and less prone to local deformation or loosening.

[0015] Option 10, which is a preferred embodiment of Option 9, involves hinged double-hole connecting plate 1 and double-hole connecting plate 2 to each other, with a handle hinged between the two double-hole connecting plates 1. Pressing the handle drives the movement of the double-hole connecting plates, making operation more convenient and quick. By applying a small force to the handle, the double-hole connecting plates can be opened and closed, thereby easily achieving the locking function of the self-locking component, reducing the difficulty of operation and improving the efficiency of use.
