Lifting machinery is a mechanical equipment driven by hydraulic cylinders or chains for lifting, mainly used for high-altitude operations and high-altitude maintenance. The safest and most reliable lifting machinery is hydraulic lifting machinery, which is driven by a hydraulic system for lifting. In the event of a sudden power outage, it will not suddenly fall. The manual valve can be operated to slowly lower the lifting machinery. The lift plays an important role in many industries. Lifting machinery is divided into: lift, lift table, hydraulic lift truck, freight elevator, fixed lift table, aluminum alloy lift, telescopic cylinder lift platform, articulated boom aerial work platform, rail-mounted lift, etc.

[0003] When the current lift is in use, universal wheels are installed at the bottom end of the lift, so as to facilitate the overall movement of the lift to a designated location, and then the staff can perform lifting operations. However, when the universal wheels are in use, the rollers contact and rub against the ground, resulting in wear of the rollers. Moreover, the universal wheels themselves have a locking function. After the staff move the lift to the designated location, only through the locking function of the universal wheels themselves, the lift is fixed to the ground. However, the worn universal wheels slide after self-locking, which causes the lift to have a horizontal offset during the lifting operation, thus affecting the normal work of the staff. Therefore, a lift with strong stability is provided. Content of the Utility Model

[0004] The purpose of the utility model is to provide a lift with strong stability, so as to solve the problem that the position of the current lift is mostly fixed through the self-locking function of the universal wheels, but the worn universal wheels cannot ensure the overall stability of the lift during the lifting operation, resulting in a horizontal offset of the lift during work as mentioned in the above background technique.

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] The following will further elaborate on the present utility model in conjunction with the attached Figures 1-5 drawings.

[0022] Please refer to Figures 1-5 , an embodiment of a lift with strong stability provided by the present utility model: A lift with strong stability includes a base 1. A plurality of uniformly distributed universal wheels 2 are fixed to the bottom end of the base 1 by bolts. The universal wheels 2 are used for the base 1 to move on a horizontal ground. A lifting seat 3 is arranged at the top end of the base 1. The lifting seat 3 is used for the lifting of the staff; A reinforcement mechanism 4 is arranged on both sides of the base 1. The reinforcement mechanism 4 is used to separate the universal wheels 2 from the ground, and after separation, increase the stability between the base 1 and the ground. The reinforcement mechanism 4 includes hydraulic rods 401 fixed to both sides of the base 1 by bolts. A fixed seat 4011 is arranged at the output end of the hydraulic rod 401. A fixing box 403 is fixed to one side of the base 1 by bolts. The fixing box 403 is located at one end of the hydraulic rod 401. A reinforcement rod 408 is sleeved inside the fixing box 403. When the output end of the hydraulic rod 401 moves downward, it can drive the fixed seat 4011 to move. After the fixed seat 4011 contacts the ground, the universal wheels 2 can be separated from the ground. When the reinforcement rod 408 rotates, it can contact the ground, thereby increasing the stability between the base 1 and the ground after movement;

[0023] The outer wall of the output end of the hydraulic rod 401 is fixed with a moving rod 402 through bolts. One end of the moving rod 402 penetrates into the inside of the fixed box 403. And a limiting groove 4031 is opened at one end of the fixed box 403. The limiting groove 4031 is used to limit the moving rod 402. And the limiting groove 4031 is used to ensure the stability of the vertical movement of the moving rod 402. When the output end of the hydraulic rod 401 moves downward, it can drive the moving rod 402 to move. A limiting column 4021 is sleeved inside the moving rod 402. The top and bottom ends of the limiting column 4021 are respectively fixed with fixing blocks 4022 through bolts. One side of the fixing block 4022 is fixedly connected with the outer wall of the base 1 through bolts. The limiting column 4021 and the fixing block 4022 are used to limit the moving rod 402. And are used to ensure the stability of the vertical movement of the moving rod 402. A sliding block 404 is arranged inside the fixed box 403. The sliding block 404 is located below the moving rod 402. And a rack 405 is fixed to the top end of the sliding block 404 through bolts. After the moving rod 402 moves downward and contacts the top end of the sliding block 404, when the moving rod 402 continues to move, it can squeeze the sliding block 404 to move downward. The movement of the sliding block 404 can drive the rack 405 to move downward.

[0024] A limiting rod 4041 is sleeved inside the sliding block 404. The bottom end of the sliding block 404 is fixedly connected with a spring 4042. The spring 4042 is sleeved outside the limiting rod 4041. And the bottom end of the spring 4042 is fixedly connected with the inner wall of the fixed box 403. The limiting rod 4041 is used to limit the sliding block 404. And the spring 4042 is used to provide a restoring force for the vertical movement of the sliding block 404. At the same time, the spring 4042 is used to maintain the initial state of the sliding block 404. One side of the rack 405 is meshed with a spur gear 406. One end of the spur gear 406 is welded with an outer wall of a rotating rod 407 which is fixedly connected with a reinforcing rod 408. And the rotating rod 407 is rotationally connected with the inner wall of the fixed box 403 through a bearing. When the rack 405 moves downward, it can drive the spur gear 406 to rotate. The rotation of the spur gear 406 drives the rotating rod 407 to rotate. The rotation of the rotating rod 407 can drive the reinforcing rod 408 to rotate. Thus, it is convenient for the reinforcing rod 408 to contact the ground. A storage groove 4032 is opened on one side of the fixed box 403. The storage groove 4032 matches the rotation track of the reinforcing rod 408. The storage groove 4032 is used to store the reinforcing rod 408. Thus, the occupied space of the reinforcing rod 408 when not in use is reduced.

[0025] Working principle: When in use, first, the universal wheels 2 roll on the ground, and the base 1 and the lifting seat 3 can be moved as a whole to a designated location. Then, the user controls the hydraulic rod 401 to work. The output end of the hydraulic rod 401 moves downward and drives the fixed seat 4011 to move. After the fixed seat 4011 contacts the ground, the hydraulic rod 401 continues to work. At this time, the force exerted by the fixed seat 4011 on the ground is converted into an upward driving force of the hydraulic rod 401, that is, the hydraulic rod 401 and the base 1 move upward. The movement of the base 1 drives the universal wheels 2 to move. At this time, the universal wheels 2 are separated from the ground, and the base 1 can be initially stabilized through the fixed seat 4011;

[0026] Secondly, while the output end of the hydraulic rod 401 moves downward, it drives the moving rod 402 to move downward. The moving rod 402 moves and contacts the top of the sliding block 404, and then squeezes the sliding block 404 to move downward. The movement of the sliding block 404 drives the rack 405 to move downward. The movement of the rack 405 drives the spur gear 406 to rotate. The rotation of the spur gear 406 drives the rotating rod 407 to rotate. The rotation of the rotating rod 407 drives the reinforcing rod 408 to rotate. At this time, the reinforcing rod 408 rotates out of the inside of the storage groove 4032, and when the universal wheels 2 are separated from the ground, the reinforcing rod 408 rotates and abuts against the ground, that is, the stability of the base 1 during operation can be increased secondarily through the rotating reinforcing rod 408;

[0027] Finally, through the setting of the hydraulic rod 401 and the fixed seat 4011, it is convenient to separate the universal wheels 2 from the ground, thereby increasing the stability of the base 1 in the working state. Compared with the traditional method of only stabilizing through the self-locking function of the universal wheels 2, the stability of the base 1 in the working state is improved. And through the same power source to drive the reinforcing rod 408 to rotate, the rotated reinforcing rod 408 abuts against the ground, further improving the stability of the base 1 in the working state, and avoiding the situation that the base 1 slides in position due to the wear of the outer wall of the universal wheels 2 during operation.

[0028] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
