Description

Technical Field

[0001] The present invention relates to the technical field of elevators, in particular to an elevator suitable for working in a dusty environment. Background Art

[0002] In the field of industrial automation and heavy equipment, lifting mechanisms are widely used in equipment such as radar antennas and palletizers to achieve vertical lifting and lowering of objects. However, existing lifting mechanisms have significant technical defects in high dust environments or conditions with frequent load changes, seriously affecting equipment reliability and maintenance costs. These problems are mainly categorized into the following two aspects:

[0003] 1. Lubrication contamination problem of rails and joint structures:

[0004] Existing lifting mechanisms (such as large radar antenna lifting mechanisms, palletizer lifting mechanisms, etc.) mostly use rail structures or rotary joint structures to achieve lifting movements. This type of structure relies on continuous lubrication in the rails or joints to reduce friction losses, but in high-dust environments, lubricating grease easily combines with dust to form hardened sludge blocks. Sludge accumulation will block the rails or joint gaps, resulting in increased movement resistance, mechanism stagnation, and even accelerated mechanical wear, and in severe cases, equipment damage. Frequent cleaning and maintenance are required to maintain normal operation, which not only increases labor costs but also reduces the applicability of the equipment in harsh environments;

[0005] 2. Problems of loosening and winding of rope / belt drive:

[0006] Existing lifting mechanisms often utilize ropes or belts, driven by a winch, to achieve lifting and lowering. However, this design has inherent flaws during the descent process: when the mechanism decelerates or grabs cargo, the weight of the lifting structure is partially transferred to the cargo, causing the tension in the ropes or belts to drop sharply or even disappear completely. At this point, the ropes or belts lose tension and become slack, making them prone to tangling, overlapping, or knotting. This not only affects lifting accuracy but also requires frequent downtime for rope adjustment or replacement, reducing work efficiency and increasing maintenance costs. Summary of the Invention

[0013] Preferably, the auxiliary lifting assembly includes a sleeve rod, and the two ends of the bottom surface of the frame are fixedly connected with the sleeve rods, and the reinforcing rods are fixedly connected around the surface of the sleeve rod and between the frames. Pulley holes are respectively provided around the surface of the sleeve rod, and pulley parts are respectively installed on the surface of the sleeve rod.

[0014] Preferably, the pulley component includes a pulley rod, and pulley rods are fixedly connected to both sides of the sleeve rod surface, and pulleys are rotatably connected to both ends between the two groups of pulley rods, and the pulleys are located in the pulley holes and rotate.

[0020] 2. The device can provide the wire rope with a maximum pre-tensioning buffer stroke of 10 cm through the spring in the buffer. This is because when the suction cup assembly falls above the stacked object to be transported, the trigger sensor starts to send a signal to the winch and stops the winch. However, during this time, the winch will release an additional 0-3 cm of the wire rope, and this extension will be absorbed by the buffer, providing a tensioning force of about 50 N or more to ensure that the wire rope does not relax or overlap. (When the wire rope is lifting the suction cup assembly, the suction cup assembly will stretch the spring in the buffer under its own weight. When the suction cup assembly is placed on the stacked object, the spring will no longer be under force, so it will begin to retract and tighten the wire rope).

[0021] 3. This device can be used for radar lifting operations, meeting the needs of military radars in complex outdoor working conditions. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0043] Embodiment: The present invention provides a technical solution for an elevator suitable for working in a dusty environment, such as Figures 1-12As shown, it includes a frame assembly 100, a lifting frame assembly 200 is installed above the frame assembly 100, a walking assembly 300 is installed in the middle of the bottom surface of the lifting frame assembly 200, and the lifting frame assembly 200 is located on the frame assembly 100 through the walking assembly 300. Auxiliary lifting assemblies 400 are respectively installed on the bottom surface of the lifting frame assembly 200 and on both sides of the walking assembly 300. A suction cup assembly 500 is slidably connected in the auxiliary lifting assembly 400. A lifting assembly 600 and a turbine-type negative pressure machine 700 are respectively installed on the top surface of the lifting frame assembly 200. The lifting assembly 600 is used to control the lifting and lowering of the suction cup assembly 500, and the output end of the turbine-type negative pressure machine 700 is connected to the suction cup assembly 500.

[0044] The device adopts an open track and non-lubricating oil design. That is, all sliding parts do not use prefabricated steel guide rails, but wheel rails, eliminating lubrication. It can operate in dusty environments without dust accumulation or sludge agglomeration, thus avoiding the problem of various dusts invading the structure and causing jamming.

[0045] The lifting assembly 600 includes a winch 601 and a hook plate 602. The top surface of the lifting frame assembly 200 is fixedly connected to the winch 601 and the hook plate 602 respectively. The bottom surface of the hook plate 602 is fixedly connected to a lifting ring 603. A buffer is hung on the lifting ring 603. A steel wire rope 604 is wound around the surface of the winch 601, and one end of the steel wire rope 604 is connected to the buffer.

[0046] The lifting and lowering of the suction cup assembly are achieved through the cooperation of the buffer, winch and wire rope. When the suction cup assembly falls above the stacked object to be transported, the trigger sensor starts to send a signal to the winch and stops the winch. However, during this time, the winch will release the wire rope an additional 0-3cm in length, and this extension will be absorbed by the buffer and provide a tensioning force greater than or equal to 50N to ensure that the wire rope does not relax and does not overlap or entangle.

[0047] As an embodiment, the buffer includes a sleeve 605, an I-shaped plate 606 is installed on the upper part of the inner cavity of the sleeve 605, the top surface of the I-shaped plate 606 is fixedly connected to an upper hook 607, the upper hook 607 is suspended from the hanging ring 603, the bottom surface of the I-shaped plate 606 is fixedly connected to springs 608 at equal intervals, the bottom surface of the spring 608 is fixedly connected to a sliding column 609, the sliding column 609 is located in the sleeve 605 and slides, the surface of the sliding column 609 is fixedly connected to a blocking ring 610, the bottom surface of the sliding column 609 is fixedly connected to a lower hook 611, and the lower hook 611 is connected to one end of the wire rope 604.

[0048] Since the blocking ring 610 slides in the sleeve 605, when the bottom surface of the blocking ring 610 contacts the bottom surface of the inner wall of the sleeve 605, it will also mean that the sliding column 609 moves downward to the maximum stroke, so that the sliding column 609 can no longer move downward. At this time, the maximum descending stroke of the sliding column 609 is 10 cm. At the same time, it also prevents the spring 608 from being over-stretched, causing damage to the spring 608.

[0049] As an embodiment, the lifting frame assembly 200 includes a frame 201, and the two ends of the bottom surface of the frame 201 are fixedly connected with wheel plates 202, and the two ends of the bottom surface of the wheel plates 202 are respectively installed with load-bearing wheels 203, and the four sides of the bottom surface of the frame 201 are respectively fixedly connected with wheel rods 204, and a limiting wheel 205 is installed on one side of the wheel rod 204.

[0050] Since the load-bearing wheel 203 is in contact with the top surface of the transverse frame 101, it ensures that when the load-bearing wheel 203 rotates, the skeleton 201 is located on the transverse frame 101 for walking; when walking, the limiting wheel 205 is in contact with the inner side wall of the transverse frame 101, preventing the load-bearing wheel 203 from detaching from the top surface of the transverse frame 101.

[0051] As an embodiment, the travel assembly 300 includes two sets of mounting plates 301. The bottom surface of the frame 201 is fixedly connected to each mounting plate 301. A travel motor 302 and a reducer 303 are fixedly connected to one side of each mounting plate 301. The output end of the travel motor 302 is fixedly connected to the output end of the reducer 303, and the output end of the reducer 303 is fixedly connected to a synchronous wheel 304. The synchronous wheel 304 and auxiliary wheel 305 are rotatably connected between the two sets of mounting plates 301. Two sets of auxiliary wheels 305 are provided, distributed in a triangular shape between the two sets of mounting plates 301.

[0052] Since the synchronous belt 102 is inserted between the synchronous wheel 304 and the auxiliary wheel 305, the auxiliary wheel 305 can ensure that the synchronous belt 102 is always engaged with the synchronous wheel 304. At this time, under the action of the walking motor 302 and the reducer 303, the walking component 300 can drive the lifting frame component 200 to walk on the frame component 100.

[0053] As an embodiment, the auxiliary lifting assembly 400 includes a sleeve rod 401, and the sleeve rods 401 are fixedly connected to the two ends of the bottom surface of the skeleton 201. Reinforcement rods 402 are fixedly connected to the four sides of the surface of the sleeve rod 401 and located between the skeleton 201. Pulley holes 403 are respectively provided around the surface of the sleeve rod 401. Pulley components are respectively installed on the surface of the sleeve rod 401. There are 4 groups of pulley components, and the surface of one of the sleeve rods 401 is fixedly connected to a positioning proximity switch 404.

[0054] The connection between the sleeve rod 401 and the lifting frame assembly 200 is made more secure by using multiple sets of reinforcing rods 402;

[0055] The design of the four pulley components ensures that the vertical rod 501 slides inside the sleeve rod 401 on the one hand, and ensures that the vertical rod 501 does not contact the inner wall of the sleeve rod 401 on the other hand, thereby reducing friction.

[0056] As an embodiment, the pulley component includes a pulley rod 405, and the pulley rods 405 are fixedly connected to both sides of the surface of the sleeve rod 401, and the two ends between the two groups of pulley rods 405 are rotatably connected to pulleys 406, which are located in the pulley hole 403 and rotate.

[0057] The pulley 406 ensures that the friction of the vertical rod 501 is reduced during the lifting process of the vertical rod 501, thereby increasing the service life of the vertical rod 501.

[0058] As an embodiment, the suction cup assembly 500 includes a vertical rod 501, the vertical rod 501 is slidably connected inside the sleeve rod 401, the bottom surface of the vertical rod 501 is fixedly connected to the suction cup frame 502, the middle part of the bottom surface of the suction cup frame 502 is fixedly connected to the square plate 503, the middle part of the top surface of the square plate 503 is symmetrically installed with a hanging wheel 504, the top surface of the square plate 503 is fixedly connected to the air distribution pipe 505, vacuum suction cups 506 are respectively installed at both ends of the suction cup frame 502, and there are 8 groups of vacuum suction cups 506. One side of the suction cup frame 502 is fixedly connected to a travel rod 507.

[0059] The air distribution pipe 505 facilitates the subsequent connection of the turbine negative pressure machine 700 and the eight groups of vacuum suction cups 506 through multiple sections of hoses, so that the whole forms a suction lifting machine, which is convenient for the subsequent suction and lifting of objects.

[0060] The sliding of the lifting wheel 504 on the wire rope facilitates the subsequent lifting assembly 600 to lift and lower the entire suction cup assembly 500.

[0061] When the positioning proximity switch 404 is triggered by the travel rod 507 , it means that the suction cup assembly 500 has risen to the maximum stroke, and the suction cup assembly 500 cannot rise again.

[0062] As an embodiment, the frame assembly 100 includes a transverse frame 101, a synchronous belt 102 is fixedly connected to the middle of the top surface of the transverse frame 101, the synchronous belt 102 is meshed with the synchronous wheel 304, the two ends of one side of the transverse frame 101 are respectively fixedly connected with a limit switch 103, a wiring component is installed on the other side of the transverse frame 101, and a control box 104 is fixedly connected to the other side of the transverse frame 101.

[0063] The two sets of travel switches 103 are used to prevent the lifting frame assembly 200 from being separated from both ends of the transverse frame 101 when the lifting frame assembly 200 is moving on the transverse frame 101 .

[0064] As an embodiment, the routing component includes a tripod 105, and the tripod 105 is fixedly connected to the other side of the transverse frame 101 at equal intervals. The top surface of the tripod 105 is fixedly connected to a U-shaped plate 106, and a flexible support chain 107 is placed inside the U-shaped plate 106.

[0065] The flexible support chain 107 is used to protect and store the cables, and ensure that the cables can operate normally in an environment where they are frequently moved and bent.

[0066] When the present invention is specifically implemented:

[0067] When in use: When moving laterally, first, start the travel motor 302. When the travel motor 302 is working, it will drive the synchronous wheel 304 to rotate under the action of the reducer 303. When the synchronous wheel 304 rotates, it will cooperate with the auxiliary wheel 305 to make the synchronous wheel 304 move on the synchronous belt 102. When the synchronous wheel 304 rotates, it will drive the skeleton 201 to move. When the skeleton 201 moves, it will be under the action of the bearing wheel 203 and the limiting wheel 205, so that the skeleton 201 is located on the transverse frame 101 and moves smoothly;

[0068] When the skeleton 201 moves, it drives the auxiliary lifting assembly 400, the suction cup assembly 500, the lifting assembly 600 and the turbine negative pressure machine 700 to move as a whole. When the skeleton 201 moves to the designated position, the travel motor 302 stops working. At this time, under the action of the speed reducer 303, the skeleton 201 is stably stopped at the designated position of the transverse frame 101.

[0069] When hoisting objects, the hoist 601 is started. When the hoist 601 is working, the wire rope 604 is released. When the wire rope 604 is released, the entire suction cup assembly 500 moves downward under the action of gravity. As the suction cup frame 502 and the vertical rod 501 move downward, the vertical rod 501 slides inside the sleeve rod 401. When the bottom of the vacuum suction cup 506 contacts the stacked objects, the suction cup frame 502 moves downward under its own weight and drives the trigger switch to move downward ( Figure 6The trigger switch is shown but not numbered), causing the suction cup frame 502 and one of the vacuum cups 506 to move relative to each other. At this time, the tail end of the vacuum cup 506 will contact the trigger switch, which provides a signal to stop the hoist 601. At the same time, the hoist 601 is internally locked. When the suction cup frame 502 and the vacuum cup 506 are located on the stacked objects, the wire rope 604 is no longer under pressure. At the same time, the spring 608 is also no longer under pressure, causing the spring 608 to contract and tighten the wire rope 604.

[0070] During adsorption, the turbine negative pressure machine 700 is started. When the turbine negative pressure machine 700 is working, the air distribution pipe 505 is first vacuumed through the pipeline, and the air distribution pipe 505 is connected to the vacuum suction cup 506 through the external pipeline. Therefore, the vacuum suction cup 506 is vacuumed, which is convenient for the subsequent adsorption of the material.

[0071] After adsorption, the winch 601 is started. The winch 601 will lift the suction cup assembly 500 and drive the material to rise. Then, under the action of the walking assembly 300, the material is transported to the designated location, thereby realizing the transportation of the material.

[0072] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
