Description

Technical Field

[0001] This utility model relates to the field of electric hoist technology, and in particular to a dustproof electric hoist. Background Technology

[0002] Electric hoists are a common type of lifting equipment. They use a motor to drive a winding wheel to wind and unwind wire ropes vertically.

[0003] In existing technologies, such as the electric hoist with dustproof function described in patent number CN221796876U, dust is removed by sucking dust from inside the hoist casing using a fan. However, because the electric hoist is equipped with upper and lower limit switches to restrict the movement of the lever, an opening needs to be made at the front end of the hoist to maintain contact between the lever and the upper and lower limit switches. This results in the existing technology's dust removal effect being less than ideal. Furthermore, due to the continuous winding and unwinding of the wire rope, impurities and dust adhere to its surface, and the existing technology cannot effectively clean the wire rope, further degrading the dust removal effect of the electric hoist. Therefore, a dustproof electric hoist is urgently needed to solve the above-mentioned problems. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] Reference Figures 1-5 This utility model provides a dustproof electric hoist, including a body 2, a cavity defined within the body 2, a winding wheel 1 connected within the cavity, a wire rope 3 wound on the winding wheel 1, an opening on the front side of the cavity, and a fire stop limiter 4 at the top of the opening, and also includes: The lever 5 is slidably connected to the bottom of the receiving cavity and is configured to contact the fire cut-off limiter 4. A through groove is provided in the center of the lever 5, and the lead-out end of the steel wire rope 3 passes through the through groove. The cleaning brush 6 is movably connected to the top surface of the dial plate 5 near the opening. The dial plate 5 is equipped with a drive assembly, and the drive end of the drive assembly is connected to the cleaning brush 6 so that the cleaning brush 6 contacts the wire rope 3 above the through groove. The fan 7 is located on the side of the inner wall of the receiving cavity opposite the opening, and the air outlet of the fan 7 faces the opening in a horizontal direction.

[0020] This invention utilizes a slot on a lever plate 5 to limit the winding and unwinding of the wire rope 3. A cleaning brush 6 is movably connected to the lever plate 5, and the cleaning brush 6 is driven and controlled by a drive assembly. The cleaning brush 6 moves above the slot and contacts the wire rope 3 that passes through the slot. Thus, during the winding and unwinding of the wire rope 3, the cleaning brush 6 contacts the wire rope 3, thereby cleaning and removing dust from the wire rope 3. Furthermore, a fan 7 is installed in the receiving cavity, arranged opposite to the opening, with the air outlet of the fan 7 facing the opening. The air blown out by the fan 7 can directly blow the dust in the receiving cavity out through the opening, effectively removing dust from the inside of the receiving cavity and improving the dust prevention effect of the electric hoist.

[0021] In this technical solution, the upper and lower limit heights are defined by the flame cut-off limiter 4, and the electric hoist is closed by the contact between the lever 5 and the flame cut-off limiter 4, thereby limiting the position of the highest point of the wire rope 3 during winding and the lowest point during unwinding. The flame cut-off limiter 4 is a conventional design structure for electric hoists and is existing technology.

[0022] Furthermore, it also includes: The connecting seat 8 is fixedly connected to the top surface of the dial plate 5 near the opening. The main body 2 is provided with a moving component. The moving end of the moving component is connected to the connecting seat 8. A sliding groove is opened at the bottom of the receiving cavity. The sliding groove connects the main body 2 with the outside. The dial plate 5 is slidably connected in the sliding groove. The dial plate 5 moves along the length of the opening.

[0023] By setting a movable component on the main body 2 and connecting the movable component to the connecting seat 8, and using the connecting seat 8 to fix the dial plate 5, the dial plate 5 slides along the slide groove. The through groove opened on the dial plate 5 limits the steel wire rope 3, so that the steel wire rope 3 is evenly wound on the winding wheel 1 during the winding process.

[0024] Understandably, the chute's vertical projection covers one side of the winding wheel 1, allowing the wire rope 3 to pass through the deflector plate 5 vertically and be wound up and down via the winding wheel 1.

[0025] Furthermore, the driving components include: The miniature geared motor 9 is fixedly connected to one side of the connecting seat 8. The connecting seat 8 has a groove on the side near the winding wheel 1. A rotating shaft 10 is rotatably connected in the groove. The output shaft of the miniature geared motor 9 is coaxially fixedly connected to the rotating shaft 10. A support rod 11 is fixed to the outer wall of the rotating shaft 10. One end of the support rod 11 extends horizontally and is fixed to a mounting plate 12. A pair of clamps 13 are arranged opposite each other on the mounting plate 12. The lead end of the wire rope 3 passes between the pair of clamps 13. A cleaning brush 6 is fixed to the side of the pair of clamps 13 that is close to each other. The pair of clamps 13 are configured to be able to move closer to each other or further apart.

[0026] The micro geared motor 9 rotates the shaft 10, causing the support rod 11 fixed to the side wall of the shaft 10 to rotate, thereby driving the mounting plate 12 to extend horizontally toward the winding wheel 1. The steel wire rope 3 is clamped by a pair of clamping plates 13 arranged opposite to each other on the mounting plate 12. By adjusting the distance between the pair of clamping plates 13, the cleaning brush 6 can effectively contact the steel wire rope 3. As the steel wire rope 3 is wound and unwound, the surface of the steel wire rope 3 is cleaned.

[0027] In this technical solution, the micro geared motor 9 adopts a common micro DC geared motor. By enhancing the output transmission ratio, the driving stability of the rotating shaft 10 can be effectively improved, thereby improving the stability and accuracy of the rotation angle of the support rod 11.

[0028] Specifically, since the horizontal distance between the connecting seat 8 and the wire rope 3 remains stable, the mounting plate 12 is rotated by using a support rod 11 of fixed length. When cleaning is not required, the micro geared motor 9 is used to rotate the shaft 10, which rotates the support rod 11, the mounting plate 12, and the clamping plate 13 to be distributed in the vertical direction, thus avoiding prolonged contact between the cleaning brush 6 and the wire rope 3.

[0029] Furthermore, the mounting plate 12 has a mounting groove on the side near the winding wheel 1, and a bidirectional lead screw 14 is rotatably connected in the mounting groove. A servo motor 15 is fixedly connected to one side of the mounting plate 12. The output shaft of the servo motor 15 is coaxially fixedly connected to the bidirectional lead screw 14. Slider 16 is threaded on both ends of the bidirectional lead screw 14 along the center symmetrical axis. The two sliders 16 are fixedly connected to a pair of clamping plates 13 one by one.

[0030] The servo motor 15 drives the bidirectional lead screw 14 to rotate, and the two sliders 16 move closer or further apart, which in turn moves a pair of clamping plates 13 closer or further apart, so that the cleaning brush 6 can effectively contact the wire rope 3. During the rotation of the support rod 11, the pair of clamping plates 13 are first moved further apart to facilitate the wire rope 3 to extend between the pair of clamping plates 13. After the clamping plates 13 are horizontally distributed, the pair of clamping plates 13 are then controlled to move closer together, and the cleaning brush 6 is used to clean the surface of the wire rope 3.

[0031] Furthermore, the cleaning brush 6 is made of nylon, which improves its durability.

[0032] Furthermore, a servo cylinder 17 is fixedly connected to one side of the outer wall of the main body 2, and the piston rod of the servo cylinder 17 extends horizontally and is fixedly connected to the connecting seat 8.

[0033] The servo cylinder 17 pushes the connecting seat 8 in the horizontal direction. The connecting seat 8 is fixed to the dial plate 5, so that the dial plate 5 can move along the length of the opening. When winding the wire rope 3, the wire rope 3 can be evenly wound on the winding wheel 1.

[0034] Furthermore, a contact plate 18 is integrally formed and fixed to the side of the lever 5 near the opening. The contact plate 18 extends vertically upward and is used to contact the flameout limiter 4.

[0035] The contact plate 18 contacts the upper and lower limit ends of the fire cut-off limiter 4, so that the wire rope 3 is continuously wound up and unwound as the lever 5 moves. When the contact plate 18 contacts the fire cut-off limiter 4, the electric hoist is stopped suddenly, thus limiting the winding and unwinding height of the wire rope 3.

[0036] Furthermore, a limiting block 19 is fixedly connected to the bottom end of the contact plate 18, and a limiting groove is formed on the inner wall of the bottom end of the receiving cavity along the length of the opening, and the limiting block 19 slides in the limiting groove.

[0037] By opening a limiting groove parallel to the slide groove and fixing a limiting block 19 to the bottom of the contact plate 18, the movement stability of the lever plate 5 and the contact plate 18 is improved through the limiting block 19 and the limiting groove.

[0038] Furthermore, it also includes: A plurality of semiconductor cooling chips 20 are provided, and the plurality of semiconductor cooling chips 20 are sequentially fixed to the bottom end of the receiving cavity along the opening width direction. The cooling surface of the semiconductor cooling chip 20 is located inside the receiving cavity, and the heat dissipation surface of the semiconductor cooling chip 20 is arranged on the bottom surface of the body 2. An external power supply 21 is fixed to one side of the outer wall of the body 2, and the external power supply 21 is electrically connected to the plurality of semiconductor cooling chips 20.

[0039] By energizing a number of semiconductor cooling chips 20 through an external power supply 21, the semiconductor cooling chips 20 cool the cavity, allowing the fan 7 to remove dust from the body 2 while the airflow is combined with the semiconductor cooling chips 20 to achieve efficient heat dissipation for the electric hoist. Furthermore, by placing the heat dissipation surface of the semiconductor cooling chips 20 outside the body 2, the impact of heat radiation on the electric hoist is reduced, thereby improving the performance of the electric hoist.

[0040] This utility model provides a working principle for a dustproof electric hoist: The steel wire rope 3 is passed through a slot opened on the lever plate 5. As the motor drives the winding wheel 1 to rotate, the steel wire rope 3 passes through the slot. The cleaning brush 6 is fixed by the support rod 11 and the support plate. The servo motor 15 rotates the bidirectional screw 14, which brings the pair of support plates closer together, so that the cleaning brush 6 contacts the steel wire rope 3, thus cleaning the steel wire rope 3. The fan 7 blows air out of the opening to blow out the dust in the body 2, improving the dust prevention effect of the electric hoist.
