Description

Technical Field

[0001] This utility model relates to a lifting device, and more particularly to an auxiliary device for lifting tubular membranes. Background Technology

[0002] Tubular membranes, as a highly efficient separation component, have been widely used in filtration and separation processes in water treatment, food processing, and biopharmaceuticals. During system installation and maintenance, tubular membrane modules exceeding 3 meters in length often require vertical hoisting or horizontal relocation. Due to the slender, cylindrical structure of the tubular membrane, its uneven axial mass distribution leads to significant center-of-gravity shift issues during traditional hoisting processes.

[0003] Chinese patent CN216784973U discloses a film roll lifting device, including a base box. Slide rails are centrally mounted on both sides of the top of the base box, and a single top seal is mounted on the top of the two slide rails. Handrails are mounted on the lower back of the slide rails. A screw jack is centrally mounted inside the base box, with the screw passing through the top of the base box and movably connected to the bottom of the top seal. A slider is positioned between the two slide rails. Several buffer springs are mounted on the top and bottom surfaces of the slider. A buffer plate is mounted at the end of the buffer springs on the same surface. A motor cylinder is mounted on the front of the slider, and a gripping mechanism, including a gripping frame, is mounted on the front of the motor cylinder. This device can prevent collisions during slider lifting and lowering, and also facilitates adjustment of the gripping mechanism's angle, improving its stability.

[0004] In the aforementioned patent, when lifting the film roll, the center of gravity of the entire device shifts upward as the lifting height increases, resulting in reduced stability and a tendency to tip over. Utility Model Content

[0005] To address the problems existing in the aforementioned patents, this utility model provides an auxiliary device for tubular membrane lifting that can increase stability during use.

[0006] The technical solution of this utility model is as follows: an auxiliary device for lifting tubular membranes, comprising a lifting machine, a clamping assembly, a connecting plate, a counterweight, a first moving wheel, a second moving wheel, a drive mechanism, and a linkage mechanism. The clamping assembly is mounted on the lifting machine, which drives the clamping assembly to move up and down. The clamping assembly is used to clamp the tubular membrane and can also extend and retract, thereby moving the tubular membrane horizontally. A connecting plate is slidably connected to the lower rear side of the lifting machine, and a counterweight is mounted on the connecting plate. The first moving wheel is mounted on the connecting plate. A drive mechanism is installed inside the lifting machine. When the clamping assembly rises, it drives the drive mechanism to run, thereby moving the counterweight and the first moving wheel backward from inside the lifting machine through the connecting plate. A linkage mechanism is installed at the lower part of the lifting machine, and a second moving wheel is mounted on the linkage mechanism, which drives the second moving wheel to move.

[0007] As a preferred technical solution of this utility model, the driving mechanism includes a push rod, a first return spring, a first rack, a gear, and a second rack. The push rod is slidably connected inside the hoist. The push rod is n-shaped and can contact the push rod when the clamping assembly moves upward. The top of the push rod is connected to the hoist with the first return spring. The bottom two ends of the push rod are connected to the first rack. The lower part of the hoist is symmetrically connected to the gear. The first rack meshes with the gear. The front side of the connecting plate is symmetrically connected to the second rack, which meshes with the gear.

[0008] As a preferred technical solution of this utility model, the linkage mechanism includes a third rack, a push rod, a sleeve, and a second return spring. The push rod is slidably connected to the lower front side of the hoist. The push rod is n-shaped. The third rack is symmetrically connected to the left and right sides of the rear side of the push rod. The third rack meshes with a gear. The sleeve is slidably connected to both ends of the front side of the push rod. The second return spring is connected between the push rod and the sleeve. The second moving wheel is installed at the end of the sleeve.

[0009] As a preferred technical solution of this utility model, it also includes an anti-collision pad. An anti-collision pad is connected to the rear side of the connecting plate. The anti-collision pad can prevent the connecting plate from hitting the operator when it moves backward from inside the hoist, thus playing a protective role.

[0010] As a preferred technical solution of this utility model, it also includes a shock-absorbing pad, and the top of the top rod is connected to the shock-absorbing pad.

[0011] As a preferred technical solution of this utility model, it also includes an alarm. An alarm is installed on the lower rear side of the hoist. When the hoist is running, the alarm is activated to alert bystanders.

[0012] Beneficial effects: This utility model controls the lifting of the clamping assembly by a lifting machine, thereby realizing the lifting operation of the tubular membrane. After the clamping assembly contacts the top rod, as the clamping assembly rises, the top rod drives the first rack to move upward, which in turn drives the second and third racks to move through the gears. This causes the connecting plate to drive the counterweight and the first moving wheel to move backward, while the push rod drives the sleeve and the second moving wheel to move forward. This increases the support surface of the lifting machine, and the backward movement of the counterweight ensures the balance of the center of gravity of the clamping assembly when it extends and drives the tubular membrane forward, thereby improving the stability of the device.

Detailed Implementation

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this does not limit the scope of protection and application of the present invention.

[0020] Example: An auxiliary device for tubular membrane lifting, such as Figure 1-5As shown, the assembly includes a hoist 1, a clamping component 2, a push rod 3, a first return spring 4, a first rack 5, a gear 6, a second rack 7, a connecting plate 8, a counterweight 81, a first moving wheel 9, a third rack 10, a push rod 11, a sleeve 12, a second return spring 13, and a second moving wheel 14. The hoist 1 is equipped with the clamping component 2, which is driven by the hoist 1 to move up and down. The clamping component 2 is used to clamp the tubular membrane and can also extend and retract, thereby moving the tubular membrane horizontally. The push rod 3 is slidably connected inside the hoist 1. The push rod 3 is n-shaped and can contact the push rod 3 when the clamping component 2 moves upward. The first return spring 4 is connected between the top of the push rod 3 and the hoist 1. The first rack 5 is connected to both ends of the bottom of the push rod 3. The gear 6 is symmetrically rotated in the lower part of the hoist 1, and the first rack 5 meshes with the gear 6. The lower rear side of the hoist 1 is slidably connected to the connecting plate 8. The front side of the connecting plate 8 is symmetrically connected to the second rack 7, which meshes with the gear 6. The connecting plate 8 is provided with the counterweight 81 and the first moving wheel 9 is installed on the connecting plate 8. The hoist 1 is provided with a drive mechanism. When the clamping assembly 2 rises, it can drive the drive mechanism to run, thereby driving the counterweight 81 and the first moving wheel 9 to move backward from the hoist 1 through the connecting plate 8. The lower front side of the hoist 1 is slidably connected to the push rod 11. The push rod 11 is n-shaped. The rear side of the push rod 11 is symmetrically connected to the third rack 10, which meshes with the gear 6. The front ends of the push rod 11 are slidably connected to the sleeve 12. The push rod 11 and the sleeve 12 are connected to the second return spring 13. The second moving wheel 14 is installed at the end of the sleeve 12.

[0021] like Figure 2-4 As shown, it also includes a crash pad 15. The crash pad 15 is connected to the rear side of the connecting plate 8. The crash pad 15 can prevent the connecting plate 8 from hitting the operator when it moves backward from the hoist 1, thus playing a protective role.

[0022] like Figure 1 and Figure 3 As shown, it also includes a shock-absorbing pad 16, which is connected to the top of the top rod 3.

[0023] like Figure 2 As shown, it also includes an alarm 17, which is installed on the lower rear side of the hoist 1. When the hoist 1 is running, the alarm 17 is turned on to alert bystanders.

[0024] During the lifting operation of the tubular membrane, the clamping assembly 2 clamps the tubular membrane. Then, the lifting machine 1 moves to the desired position via the first moving wheel 9 and the second moving wheel 14. The lifting machine 1 then controls the clamping assembly 2 to move upwards, lifting the tubular membrane. As the clamping assembly 2 rises, the center of gravity of the entire device also shifts upwards, causing instability. After the clamping assembly 2 rises to contact the top rod 3, it can push the top rod 3 upwards. The first return spring 4 deforms, and the shock-absorbing pad 16 protects the top rod 3, reducing the impact force of the clamping assembly 2 on the top rod 3. The first return spring 4 also acts as a buffer. When the top rod 3 moves upwards, it drives the first rack 5 upwards, thereby driving the gear 6 to rotate counterclockwise, which in turn drives the second rack 7 to rotate... The third gear 6 moves forward, causing the connecting plate 8 to move the counterweight 81 and the first moving wheel 9 backward, while the push rod 11 moves the sleeve 12 and the second moving wheel 14 forward, thereby increasing the support surface of the elevator 1. At the same time, the backward movement of the counterweight 81 can shift the center of gravity of the entire device backward, ensuring the balance of the center of gravity of the clamping assembly 2 when it extends and moves the tubular membrane forward, thereby improving the stability of the device. If the sleeve 12 is obstructed from moving the second moving wheel 14 forward, the second moving wheel 14 and the sleeve 12 will not move, while the push rod 11 will move inward into the sleeve 12, and the second return spring 13 will deform. This can prevent the sleeve 12 from being obstructed when it moves the second moving wheel 14 outward, thus preventing the elevator 1 from being unable to move the tubular membrane to the required position.

[0025] When the hoist 1 controls the clamping assembly 2 to move downwards and reset, the top rod 3 moves downwards and resets under the action of the first reset spring 4. This causes the first rack 5 to drive the gear 6 to rotate clockwise, thereby causing the connecting plate 8 to move the counterweight 81 and the first moving wheel 9 into the hoist 1. The push rod 11 also drives the sleeve 12 and the second moving wheel 14 into the hoist 1. Thus, when the clamping assembly 2 is located at the lower position of the hoist 1, both the first moving wheel 9 and the second moving wheel 14 are located inside the hoist 1, reducing the overall volume of the device and facilitating the movement of the hoist 1.
