Abstract
Description
Technical Field
[0001] This utility model relates to the field of material transfer technology, specifically an environmentally friendly sealed anti-spillage lifting device. Background Technology
[0002] Building materials are the various materials used in construction projects. Building materials are diverse and can be broadly categorized into: inorganic materials, which include metallic materials (including ferrous and non-ferrous metals) and non-metallic materials (such as natural stone, calcined clay products, cement, concrete, and silicate products); organic materials, which include plant-based materials, synthetic polymer materials (including plastics, coatings, and adhesives), and asphalt materials; and composite materials, which include asphalt concrete, polymer concrete, etc., generally composed of inorganic non-metallic materials and organic materials.
[0003] During construction, non-metallic materials, due to their weak polymerization, are prone to dust generation when subjected to external forces, leading to a harsh environment at and around the construction site. While water mist dust suppression can effectively purify the environment, continuous atomization and humidification result in high consumption of pure water, which is not conducive to energy-efficient production. To effectively prevent dust generation and improve the site environment, we propose an environmentally friendly sealed anti-spillage lifting device. 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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0018] Please see Figures 1 to 4This utility model provides a technical solution: an environmentally friendly sealed anti-spillage lifting device, including a sealing frame 1 and a winch 9. The winch 9 consists of a geared motor, a winch roller, and a wire rope assembly, and is the drive mechanism for the lifting trolley 3. The sealing frame 1 has a sealing housing for supporting and sealing the entire device. A dust collection box 2 is movably fitted inside the sealing frame 1. The dust collection box 2 has casters and quick-clamping devices for collecting deposited dust and facilitating cleaning. Tracks are supported at the four corners of the inner side of the sealing frame 1, and the lifting trolley 3 is movably supported inside the tracks. The trolley 3 can move up and down on the track under the drive of the winch 9, lifting the material to the required floor and unloading it by flipping it over; the outer side of the sealing frame 1 is movably supported by a rotary guide plate 4, the outer side of the sealing frame 1 is fixedly supported by a feed inlet 5, the outer side of the sealing frame 1 is fixedly installed with a dust removal port 6, the top of the sealing frame 1 is supported by a pulley group 7, the pulley group 7 can be redirected to the direction of the wire rope, so that the winch 9 can be placed in a suitable position; the inner fixed set of the sealing frame 1 is a tilting frame 8, the tilting frame 8 has an arc guide rail, which can make the lifting trolley 3 perform unloading and tilting actions according to a preset trajectory.
[0019] The rotary guide plate 4 includes a striking block 4-1; a rocker plate 4-2; a rocker plate rotation shaft 4-3; a return spring 4-4; a guide plate 4-5; and a guide plate rotation shaft 4-6. The rocker plate rotation shaft 4-3 is supported on the inner side of the sealing frame 1. The guide plate 4-5 is connected to the inner wall of the sealing frame 1 through the return spring 4-4. The guide plate rotation shaft 4-6 is movably fitted on the top of the guide plate 4-5. When the trolley descends, the striking block on the trolley presses down on the rocker plate 4-2, causing the rocker plate 4-2 to lift the discharge plate, thus extending the feed inlet 5 into the hopper and preventing spillage during feeding. The feed inlet 5 is used to connect to the upper-level equipment.
[0020] The feed inlet 5 is located opposite the dust removal inlet 6, and the lifting trolley 3 is located between the feed inlet 5 and the dust removal inlet 6.
[0021] The dust collection box 2 is located near the bottom of the inner cavity of the sealed frame 1, and the tilting frame 8 is located near the top inside the sealed frame 1.
[0022] The winch 9 is externally connected to a wire rope, which is attached to the outside of the pulley block 7 and connected to the top of the lifting trolley 3.
[0023] In summary, this environmentally friendly, sealed, spill-proof lifting device works as follows: During operation, the lifting trolley 3 slowly descends from the upper track under its own weight and the combined action of the winch 9. The collision block on the lifting trolley 3 presses down on the lower end of the rocker arm 4-2 of the rotary guide plate 4. The rocker arm rotates, lifting the guide plate and extending the feed inlet into the hopper. The upper-level equipment feeds material through the feed inlet 5. The material then enters the lifting trolley 3 through the rotary guide plate 4. The dust raised is drawn into the dust collector through the dust removal port 6, maintaining a continuous negative pressure inside the equipment. After feeding is complete, the winch 9 rotates, using a wire rope and... The pulley block 7 lifts the trolley 3; the collision block on the trolley disengages from the rocker arm 4-2 on the rotary guide plate 4, and the guide chute rotates under its own weight and the action of the return spring, leaving the rising channel of the trolley to avoid collision; when the trolley 3 moves to the position of the upper tilting frame 8 under the drive of the winch 9, the upper lifting trolley wheel enters the lower guide rail, and the lower lifting trolley wheel continues to move upward into the upper arc guide rail, causing the trolley 3 to tilt and discharge the material. After completion, the winch 9 reverses the trolley back along the original path, completing one material conveying cycle.
