Description

Technical Field

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

[0002] A hoisting device is a combination of equipment and tools that uses various mechanical structures, power systems, and load-bearing components to lift, lower, translate, and rotate heavy objects to perform tasks such as hoisting, moving, and installing them. It consists of multiple parts, including a power source, transmission device, load-bearing mechanism, control system, and safety protection devices. It can move heavy objects from one location to another designated location and plays a vital role in construction, port logistics, mining, industrial manufacturing, equipment maintenance, and many other fields. It is a key piece of equipment for material handling and equipment installation.

[0003] A search revealed Chinese Patent Publication No. CN115583608A, which discloses a lifting device, relating to the field of lifting device technology. The lifting device includes a three-dimensional motion mechanism, a lifting and traveling mechanism, and a suspension mechanism. The suspension mechanism is located within the three-dimensional motion mechanism and is used to drive the suspension mechanism to move along the lateral, longitudinal, and longitudinal directions of the lifting device. The lifting and traveling mechanism includes a main lifting and traveling frame and a secondary lifting and traveling frame. The secondary lifting and traveling frame is slidably mounted on the main lifting and traveling frame, which is located within the three-dimensional motion mechanism. This invention allows for position adjustment, facilitating the lifting of molds with high precision, thus improving mold installation efficiency. However, in existing lifting devices, when lifting and transferring items, the items swing left and right due to their own weight and inertia. This swinging cargo can collide and rub against surrounding items and the lifting frame, potentially damaging the lifting frame and surrounding objects. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a hoisting device, which aims to improve the problem in the prior art where, when hoisting and transferring items, the hoisted items swing left and right due to their own weight and inertia, and the swinging items collide and rub against surrounding items and the hoisting frame, thereby causing damage to the hoisting frame and surrounding objects.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a hoisting device, including a hoist, a storage box installed at the bottom of the hoist, multiple fixing blocks fixedly connected at equal intervals around the outer wall of the storage box, a fixed long rod fixedly connected to the middle of the fixing block, a fixing plate fixedly connected to the other end of the outer wall of the fixing long rod, a spring fixedly connected to the left side of the outer wall of the fixing plate, a moving block slidably connected to the outer wall of the fixing long rod, the left side of the outer wall of the moving block being fixedly connected to the other end of the outer wall of the spring, a rotating rod one rotatably connected to the upper and lower sides of the outer wall of the fixing block, a rotating rod two rotatably connected to the upper and lower sides of the outer wall of the moving block, an elongated sliding plate slidably connected to the other end of the outer wall of the rotating rod one, an arc-shaped plate fixedly connected to the front side of the outer wall of the elongated sliding plate, and a dust removal mechanism installed at the top of the hoist, the dust removal mechanism being used to remove dust from the quartz sand during hoisting and transfer.

[0006] The above technical solution involves lifting the quartz sand using a storage box. When the storage box moves and swings, the impact force is transmitted through the arc-shaped plates around its outer wall to the rotating rod 1 at the bottom and the rotating rod 2 on the moving block, causing the two rotating rods to rotate. Because the moving block and the rotating rod 2 are rotatably connected, when the rotating rod 2 rotates, it pushes the moving block to slide on the fixed long rod, squeezing the spring on the left side of the outer wall of the fixed plate. The extension and contraction of the spring can play a buffering role, reducing the impact damage to the hanger and storage box 4 caused by shaking and collision, thereby improving the stability and safety of the lifting device.

[0007] As a further description of the above technical solution:

[0008] The dust removal mechanism includes a support frame, which is installed on the top of the hanger. A motor is fixedly connected to the left side of the outer wall of the support frame. A first rotating wheel is rotatably connected to the output end of the motor. A second rotating wheel is rotatably connected to the upper left side of the inner wall of the support frame. A belt is installed on the outer wall of the second rotating wheel. The second rotating wheel and the first rotating wheel are connected by belt drive. Threaded rods are fixedly connected to the right side of the outer walls of both the second rotating wheel and the first rotating wheel. A movable plate is threadedly connected to the outer wall of the threaded rod. Fans are fixedly connected to the left and right sides of the bottom of the upper movable plate. A battery is fixedly connected to the middle of the bottom wall of the movable plate. Multiple nozzles are fixedly connected at equal intervals to the bottom of the lower movable plate.

[0009] The above technical solution works as follows: By turning on the motor, the first output wheel rotates. When the first wheel rotates, it is connected to the second wheel via a belt, thus driving the second wheel to rotate synchronously. Since the right side of the outer wall of both the second and the first wheel is fixedly connected with a threaded rod, when the first and second wheels rotate, the threaded rod will rotate synchronously. The outer wall of the threaded rod is threaded with a moving plate. Therefore, the rotation of the threaded rod will cause the moving plate to move left and right on the threaded rod. Then, water mist is sprayed from the nozzle at the bottom of the lower moving plate and diffused around the quartz sand and the hanger. This causes the dust particles to combine with water, increasing their weight and accelerating their settling. The fan at the bottom of the top moving plate can accelerate the speed at which the water mist adheres and falls, further reducing the dust from flying.

[0010] As a further description of the above technical solution:

[0011] A light is fixedly connected to the top of the support frame.

[0012] The above technical solution allows the lighting on the top of the support frame to provide auxiliary lighting in poorly lit environments.

[0013] As a further description of the above technical solution:

[0014] A hollow box is fixedly connected to the right side of the outer wall of the hanger, and a drawer is slidably connected inside the hollow box.

[0015] The above technical solution allows for the use of sliding drawers inside the hollow box to facilitate the storage of tools for daily use and maintenance.

[0016] As a further description of the above technical solution:

[0017] A handle is fixedly connected to the right side of the outer wall of the drawer, and an anti-slip sleeve is fixedly connected to the outer wall of the handle.

[0018] The above technical solution provides a handle fixedly connected to the right side of the outer wall of the drawer, which facilitates opening and closing the drawer.

[0019] As a further description of the above technical solution:

[0020] A screw is threadedly connected to the rear side of the middle part of the outer wall of the hanger, and a warning sign is threadedly connected to the outer wall of the screw.

[0021] The aforementioned technical solution allows the warning sign located in the middle of the outer wall of the hanger to serve as a warning to surrounding personnel and the public, thereby reducing the probability of maintenance.

[0022] As a further description of the above technical solution:

[0023] The lower rear part of the outer wall of the hanger is threaded with screw three, and the outer wall of screw three is threaded with hook.

[0024] The above technical solution allows for the use of hooks on the lower part of the outer wall of the hanger to facilitate the hanging of tools for daily use and cleaning by staff.

[0025] As a further description of the above technical solution:

[0026] The motor has feet that can be fixedly connected to the front and rear sides of its bottom, and a screw is threadedly connected to the top of each foot.

[0027] The above technical solution, with its fixed support feet at the bottom of the motor, enhances the motor's stability and prevents deviation or movement.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the impact force is transmitted to the rotating rod 1 at the bottom and the rotating rod 2 on the moving block through the arc plate, thereby causing the two rotating rods to rotate. When the rotating rod 2 rotates, it pushes the moving block to slide and compress the spring on the left side of the outer wall of the fixed plate on the fixed long rod. The extension and contraction of the spring can play a buffering role, thereby avoiding the problem that when the hoisting device lifts and transfers goods, the hoisted and transferred goods will swing left and right due to their own gravity inertia. The swinging goods will collide and rub against surrounding items and the hoisting frame, thereby causing damage to the hoisting frame and surrounding objects.

[0030] 2. In this utility model, water mist is sprayed from the nozzle and diffused around the quartz sand and the hanger. This causes the dust particles to combine with the water, increasing their weight and accelerating their settling. Then, the fan can accelerate the adhesion and descent of the water mist, further reducing the dust from flying around. This avoids the problem of dust generated during the hoisting and transfer of quartz sand causing harm to the surrounding environment and workers. Attached Figure Description

Detailed Implementation

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0039] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a hoisting device, including a hoist 1. A storage box 4 is installed at the bottom of the hoist 1. Multiple fixing blocks 16 are fixedly connected at equal intervals around the outer wall of the storage box 4. A fixing rod 19 is fixedly connected to the middle of the fixing block 16. A fixing plate 22 is fixedly connected to the other end of the outer wall of the fixing rod 19. A spring 21 is fixedly connected to the left side of the outer wall of the fixing plate 22, and the spring 21 plays a role in buffering and releasing force. A movable block 23 is slidably connected to the outer wall of the fixing rod 19. The left side of the outer wall of the movable block 23 is fixedly connected to the other end of the outer wall of the spring 21. The sliding of the movable block 23 can realize the function of compressing the spring 21 to buffer and release force. Rotating rods are rotatably connected to the upper and lower sides of the outer wall of the fixing block 16. Rotating rods 20 are rotatably connected to the upper and lower sides of the outer wall of the movable block 23. A long slide plate 17 is slidably connected to the other end of the outer wall of the rotating rod 18. An arc plate 12 is fixedly connected to the front side of the outer wall of the long slide plate 17. A dust removal mechanism 2 is installed on the top of the hanger 1. The dust removal mechanism 2 is used to remove dust from the quartz sand during hoisting and transfer. A lighting lamp 3 is fixedly connected to the top of the support frame 201.

A hollow box 11 is fixedly connected to the right side of the outer wall of the hanger 1. A drawer 15 is slidably connected inside the hollow box 11. The drawer 15 slidably connected inside the hollow box 11 can facilitate the storage of tools for daily use and maintenance.

[0040] Specifically, the quartz sand is lifted by the storage box 4. When the storage box 4 moves and swings, the impact force is transmitted through the arc-shaped plates 12 around its outer wall to the rotating rod 18 at the bottom and the rotating rod 20 on the moving block 23, causing the two rotating rods to rotate. Because the moving block 23 and the rotating rod 20 are rotatably connected, when the rotating rod 20 rotates, it pushes the moving block 23 to slide on the fixed rod 19, pressing the spring 21 on the left side of the outer wall of the fixed plate 22. The extension and contraction of the spring 21 can... The support frame 201 has a buffering effect, reducing the impact damage to the hanger 1 and storage box 4 caused by shaking and collision, thereby improving the stability and safety of the hoisting device. The top of the support frame 201 is fixedly connected to a lighting lamp 3, which can play an auxiliary lighting role in poor lighting environments. The outer right side of the hanger 1 is fixedly connected to a hollow box 11, and a drawer 15 is slidably connected inside the hollow box 11. The drawer 15 slidably connected inside the hollow box 11 can facilitate the storage of tools for daily use and maintenance.

[0041] Reference Figure 1 , Figure 2 and Figure 5The dust removal mechanism 2 includes a support frame 201, which is installed on the top of the hanger 1. A motor 207 is fixedly connected to the left side of the outer wall of the support frame 201. A first rotating wheel 205 is rotatably connected to the output end of the motor 207. A second rotating wheel 206 is rotatably connected to the upper left side of the inner wall of the support frame 201. A belt 208 is installed on the outer wall of the second rotating wheel 206. The second rotating wheel 206 and the first rotating wheel 205 are connected by the belt 208 for transmission. The belt 208 can connect the two rotating wheels and make them rotate synchronously. A threaded rod 202 is fixedly connected to the right side of the outer wall of both the second rotating wheel 206 and the first rotating wheel 205. A movable plate 209 is threadedly connected to the outer wall of the threaded rod 202. The rotation of the threaded rod 202 can drive the outer... The movable plate 209 of the wall can be adjusted to move left and right. Fans 203 are fixedly connected to the bottom left and right sides of the upper movable plate 209. A battery 204 is fixedly connected to the middle of the bottom wall of the movable plate 209. Multiple nozzles 210 are fixedly connected at equal intervals to the bottom of the lower movable plate 209. A handle 14 is fixedly connected to the right side of the outer wall of the drawer 15. The handle 14 fixedly connected to the right side of the outer wall of the drawer 15 can facilitate opening and closing the drawer 15. An anti-slip sleeve 13 is fixedly connected to the outer wall of the handle 14. A screw 8 is threadedly connected to the rear side of the middle of the outer wall of the hanger 1. A warning sign 7 is threadedly connected to the outer wall of the screw 8. The warning sign 7 in the middle of the outer wall of the hanger 1 can serve as a warning to the surrounding personnel and the public to reduce the probability of maintenance.

[0042] Specifically, by turning on the motor 207, the first output wheel 205 is driven to rotate. When the first output wheel 205 rotates, it is connected to the second output wheel 206 via the belt 208, thereby driving the second output wheel 206 to rotate synchronously. Since the right side of the outer wall of both the second output wheel 206 and the first output wheel 205 is fixedly connected with a threaded rod 202, when the first output wheel 205 and the second output wheel 206 rotate, they will drive the threaded rod 202 to rotate synchronously. The outer wall of the threaded rod 202 is threadedly connected with a moving plate 209, so the rotation of the threaded rod 202 will cause the moving plate 209 to move left and right on the threaded rod 202. Then, water mist is sprayed onto the quartz sand through the nozzle 210 at the bottom of the lower moving plate 209. The dust particles diffuse around the hanger 1, increasing their weight after combining with water, thus accelerating their settling. The fan 203 at the bottom of the top moving plate 209 can accelerate the adhesion and descent of water mist, further reducing dust re-entrainment. A handle 14 is fixedly connected to the right side of the outer wall of the drawer 15, which facilitates opening and closing the drawer 15. An anti-slip sleeve 13 is fixedly connected to the outer wall of the handle 14. A screw 8 is threadedly connected to the rear side of the middle of the outer wall of the hanger 1, and a warning sign 7 is threadedly connected to the outer wall of the screw 8. The warning sign 7 in the middle of the outer wall of the hanger 1 can serve as a warning to surrounding personnel and the public, reducing the probability of maintenance.

[0043] Reference Figure 1 and Figure 2 The lower rear side of the outer wall of the hanger 1 is threaded with screw 310, and the outer wall of screw 310 is threaded with hook 9. The hook 9 on the lower outer wall of the hanger 1 can facilitate the hanging of tools for daily use and cleaning by the staff. The bottom front and rear sides of the motor 207 are fixedly connected with support legs 5, and the top of the support legs 5 is threaded with screw 16. The support legs 5 fixedly connected to the bottom of the motor 207 can enhance the stability of the motor 207 and prevent deviation and movement.

[0044] Specifically, screw 10 is threadedly connected to the lower rear side of the outer wall of the hanger 1, and hook 9 is threadedly connected to the outer wall of screw 10. The hook 9 on the lower middle part of the outer wall of the hanger 1 can facilitate the hanging of tools for daily use and cleaning by the staff. The bottom front and rear sides of the motor 207 are fixedly connected to the support legs 5, and screw 6 is threadedly connected to the top of the support legs 5. The support legs 5 fixedly connected to the bottom of the motor 207 can enhance the stability of the motor 207 and prevent deviation and movement.

[0045] Working principle: Quartz sand is lifted by the storage box 4. When the storage box 4 moves and swings, the impact force is transmitted to the rotating rod 18 at the bottom and the rotating rod 20 on the moving block 23 through the arc plate 12 around the outer wall, causing the two rotating rods to rotate. Since the moving block 23 and the rotating rod 20 are rotatably connected, when the rotating rod 20 rotates, it pushes the moving block 23 to slide on the fixed long rod 19 and squeeze the spring 21 on the left side of the outer wall of the fixed plate 22. The extension and contraction of the spring 21 can play a buffering role, reducing the impact damage to the hanger 1 and the storage box 4 caused by shaking and collision, thereby improving the stability and safety of the lifting device. This avoids the problem that when the lifting device lifts and transfers items, the items being lifted and transferred will swing left and right due to their own gravity inertia, and the swinging goods will collide and rub against the surrounding items and the hanger 1, thus causing damage to the hanger 1 and the surrounding objects.

[0046] By activating motor 207, the first output wheel 205 rotates. When the first wheel 205 rotates, it is connected to the second wheel 206 via belt 208, causing the second wheel 206 to rotate synchronously. Since threaded rods 202 are fixedly connected to the right side of the outer walls of both the second wheel 206 and the first wheel 205, their rotation drives the threaded rods 202 to rotate synchronously. Furthermore, a movable plate 209 is threadedly connected to the outer wall of the threaded rod 202. The rotation causes the movable plate 209 to move left and right on the threaded rod 202. Then, water mist is sprayed from the nozzle 210 at the bottom of the lower movable plate 209 and diffused around the quartz sand and the hanger 1. This causes the dust particles to combine with the water, increasing their weight and accelerating their settling. Meanwhile, the fan 203 at the bottom of the upper movable plate 209 can accelerate the adhesion and descent of the water mist, further reducing the dust from flying around. This avoids the problem of dust generated during the hoisting and transfer of quartz sand causing harm to the surrounding environment and workers.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
