Description

Technical Field

[0001] This utility model relates to the field of lifting technology, specifically a material lifting machine. Background Technology

[0002] The magnet assembly process requires magnetizing the magnets and then transporting the workpieces to be magnetized. During this process, the magnet workpieces need to be lifted and lowered.

[0003] Existing material lifting equipment, especially those using single-sided chain drives, is prone to tilting or swaying when carrying heavy loads due to uneven force distribution. This affects the stability and positioning accuracy of material transport, particularly on automated production lines where materials need to be precisely conveyed to specific heights. Furthermore, inaccurate positioning can lead to deviations when docking with upstream and downstream equipment. In addition, most existing lifting equipment uses ordinary motor drives, lacking effective mechanical self-locking or braking mechanisms when stopped. This allows the lifting platform to slip slightly or fall due to inertia or load, posing safety hazards and failing to ensure reliable locking of materials at designated heights. To address these issues, we propose a material lifting platform. Utility Model Content

[0004] The purpose of this invention is to provide a material lifting platform to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a material hoist, comprising a support structure, the support structure comprising a base, a support frame and a support plate, the support frame being installed on the left side above the base, the support plate being installed on the upper inner side of the support frame, support columns being installed on both sides below the support plate, and the lower part of the support columns being installed above the base;

[0006] The lifting structure includes a rotating chain, sprockets, and fixed columns. Rotating chains are installed on the inner sides of both supporting columns. Sprockets are installed on both sides inside the rotating chains. A fixed column passes through the middle of each sprocket. Fixed plates are installed on both sides above the support plate. The right side of the upper fixed column is connected to the right fixed plate via a second bearing. The left side of the upper fixed column passes through the left fixed plate and is connected to a reduction gearbox. A brake motor is installed on the left side of the reduction gearbox. The lower fixed column is located inside a groove. Both sides of the lower fixed column are connected to the base via first bearings. The right sides of both rotating chains are connected to the lifting platform via plate chain joints. Guide pulleys are installed on both sides of the lifting platform. The guide pulleys are located inside guide rails, which are located inside the support frame.

[0007] Preferably, the support structure is fixedly connected to the support frame, and the support frame is fixedly connected to the support plate.

[0008] Preferably, the rotary chain and the support plate are arranged perpendicularly to each other, and the rotary chain and the base are fixedly connected.

[0009] Preferably, the rotary chain and the support column are arranged parallel to each other.

[0015] Preferably, the lifting platform and the rotary chain are arranged perpendicular to each other.

[0016] Compared with existing technologies, the beneficial effects of this utility model are:

[0017] Driven by the same power source through double-sided rotary chains, the lifting platform is evenly stressed on both sides, eliminating the risk of unilateral tilting and improving the load-bearing capacity of the device. When moving the lifting platform, the guide pulleys on both sides of the lifting platform are embedded in the inner side of the support frame and slide on the inner side of the guide rail, limiting horizontal deviation and ensuring stable operation in the vertical direction.

[0018] The mobile lifting platform is driven by a brake-type motor with a built-in braking function. Combined with the mechanical self-locking characteristics of the gearbox, the lifting platform can be precisely locked at a specified height when the machine stops, preventing slippage.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Please see Figure 1-3This utility model provides a material lifting platform technical solution: a material lifting platform, including a support structure 1, the support structure 1 including a base 101, a support frame 102 and a support plate 103, the support frame 102 is installed on the left side above the base 101, the support plate 103 is installed on the upper inner side of the support frame 102, the support columns 104 are installed on both sides below the support plate 103, and the lower part of the support columns 104 is installed above the base 101.

[0028] Lifting structure 2 includes a rotating chain 201, sprockets 202, and fixed columns 203. Rotating chains 201 are installed on the inner sides of both side support columns 104. Sprockets 202 are installed on both sides inside the rotating chains 201. A fixed column 203 passes through the middle of the sprockets 202. Fixed plates 204 are installed on both sides above the support plates 103. The right side of the upper fixed column 203 is connected to the right fixed plate 204 via a second bearing 205. The left side of the upper fixed column 203 passes through the left fixed plate 204 and is connected to a reduction gearbox 206. A brake motor 207 is installed on the left side of the reduction gearbox 206. The brake motor 207 has a built-in brake mechanism. When the motor 207 is powered off or receives a stop signal, the brake mechanism activates. The mechanism immediately clamps the motor shaft to prevent it from continuing to rotate. In addition to providing deceleration and torque increase, the gearbox 206 also has a mechanical self-locking characteristic. That is, when the motor 207 stops, the internal worm gear structure can achieve reverse self-locking, which further enhances the locking capability of the lifting platform 210 at any height, thereby avoiding the risk of slippage and falling. The lower fixing column 203 is located inside the groove 208. The two sides of the lower fixing column 203 are connected to the base 101 through the first bearing. The right side of the two side rotating chains 201 is connected to the lifting platform 210 through the plate chain joint 209. The two sides of the lifting platform 210 are equipped with guide pulleys 211. The guide pulleys 211 are located inside the guide rail 212. The guide rail 212 is located inside the support frame 102.

[0029] The support structure 1 is fixedly connected to the support frame 102, and the support frame 102 is fixedly connected to the support plate 103. A photoelectric stroke sensor is installed on the support frame 102 to detect the vertical position of the lifting platform 210 in real time. The sensor feeds the position data back to the control system. The control system accurately controls the start and stop of the brake motor 207 according to the preset target height, thereby achieving precise positioning of the lifting platform 210. The control system is composed of a microcontroller and is electrically connected to the brake motor 207, the gearbox 206 and the stroke sensor to realize automated and precise control of material lifting and setting, and sets multiple preset heights to improve the convenience of operation.

[0030] The rotary chain 201 and the support plate 103 are arranged perpendicularly to each other, and the rotary chain 201 and the base 101 are fixedly connected.

[0031] The rotary chain 201 and the support column 104 are arranged parallel to each other.

[0032] The upper fixed column 203 is rotatably connected to the second bearing 205, and the lower fixed column 203 is rotatably connected to the first bearing.

[0033] The fixed column 203 is fixedly connected to the sprocket 202, and the sprocket 202 is correspondingly connected to the rotary chain 201.

[0034] The fixed column 203 and the rotary chain 201 are set perpendicular to each other.

[0035] The lifting platform 210 is fixedly connected to the guide pulley 211, while the guide pulley 211 is slidably connected to the guide rail 212.

[0036] The guide rail 212 and the support frame 102 are integrated.

[0037] The lifting platform 210 and the rotary chain 201 are set perpendicular to each other.

[0038] Working principle:

[0039] First, the brake motor 207 outputs power, which is reduced and increased in torque by the gearbox 206, driving the upper fixed column 203 inside the left fixed plate 204 to rotate. The fixed column 203 is rigidly connected to the sprocket 202, and through meshing, it drives the rotating chains 201 on both sides to rotate synchronously along the inner side of the support column 104, ensuring that the lifting platform 210 is evenly stressed and avoids tilting. The lower fixed column 203 is further supported in the groove 208 of the base 101 by the first bearing, ensuring that the chain is taut and the transmission is not loose.

[0040] The right side of the rotary chain 201 is fixed to the lifting platform 210 via a plate chain joint 209. When the rotary chain 201 rotates, it drives the lifting platform 210 to rise and fall synchronously. The guide pulleys 211 on both sides of the lifting platform are embedded in the guide rails 212 inside the support frame 102 to limit horizontal deviation, ensure stable vertical operation, and stop precisely at the required position.

[0041] Although embodiments of the present utility have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present utility, the scope of which is defined by the appended claims and their equivalents.
