AI Technical Summary

Technical Problem

When existing attached cabin elevators descend under high load, the inertial impact force acts directly on the connection between the base and the column, causing deformation of the slider, cracking of the slide groove, or tearing of the column weld, which seriously threatens the service life and safety of the equipment.

Method used

The impact force is absorbed by a buffer sponge layer, transmitted to the upper support plate through a metal support plate, and dissipated through the synergistic action of the first and second damping rods and springs, thus achieving the two-stage spring deformation and damping dissipation of impact force.

Benefits of technology

It effectively absorbs and dissipates the impact energy of the lifting platform, ensuring the safety of the lifting platform, personnel, and goods, extending the equipment's lifespan, and improving operational safety.

Description

Technical Field

[0001] This utility model relates to the field of large-scale freight equipment technology, specifically an attached cabin elevator. Background Technology

[0002] As most manufacturers or individuals choose multi-story buildings to improve site utilization, a device is needed to facilitate the lifting and lowering of goods. Since ordinary elevators are expensive and have low load-bearing capacity, they are not suitable for loading large and heavy goods. Therefore, high-load-bearing attached cabin elevators have been developed to assist in production and cargo transportation. They are safe, have a huge load capacity, and are easy to maintain, which has enabled this special industry to develop more rapidly.

[0003] A search revealed Chinese Patent Publication No. CN221680704U, which discloses an attached cabin lift, including a base, a column at the top of the base, a groove on one side of the column, a slider inside the groove, a connecting block between the sliders, a support column at the bottom of the connecting block, a cargo base at the bottom of the support column, a pulley groove inside the cargo base, and a pulley inside the pulley groove. During use, especially during descent under high load, the enormous inertial impact directly acts on the connection between the base and the column, lacking effective shock absorption and energy dissipation mechanisms. This easily leads to slider deformation, groove cracking, or column weld tearing, seriously threatening equipment lifespan and operational safety, and posing a threat to cargo and even operators. Therefore, an attached cabin lift is provided to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide an attached cabin elevator to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an attached cabin elevator, comprising: a lower support platform, a wall-mounted bracket fixedly connected above the lower support platform, two sets of vertical slide rails fixedly connected to the side of the wall-mounted bracket, a drive mechanism fixedly connected above the wall-mounted bracket, a connecting chain disposed below the drive mechanism, a first connecting hook fixedly connected to the other end of the connecting chain, a loading step fixedly connected above the lower support platform, a lifting platform disposed above the lower support platform, a movable bracket fixedly connected above the lifting platform, a second connecting hook fixedly connected above the movable bracket, two sets of upper roller fixing frames symmetrically fixedly connected to the side of the movable bracket near the wall-mounted bracket, and the side of the movable bracket near the wall-mounted bracket... The device is equipped with two sets of lower roller fixing frames. Both the inner sides of the upper and lower roller fixing frames are rotatably connected to slide rails and pulleys. A buffer sponge layer is located on the inner side of the lower support platform below the lifting platform. Metal support plates are fixedly connected to the upper and lower ends of the buffer sponge layer. A lower fixing plate is fixedly connected above the inner bottom wall of the lower support platform. Several sets of connecting rod rotating seats are fixedly connected above the lower fixing plate. A first damping rod is rotatably connected to the inner side of each connecting rod rotating seat.

A second damping rod is fixedly connected between the intermediate connecting seat and the lower fixing plate. A second spring is sleeved on the outer side of the second damping rod. An upper support plate is fixedly connected above the intermediate connecting seat.

[0006] As a further embodiment of this utility model: the second connecting hook is adapted to the first connecting hook, and the annular buckles of the second connecting hook and the first connecting hook are strung together.

[0007] As a further embodiment of this utility model: the slide rail pulley is adapted to the vertical slide rail, and two sets of slide rail pulleys are rotatably connected to the inner side of the upper roller fixing frame. The two sets of slide rail pulleys are located on the two sides of the vertical slide rail at corresponding positions and abut against each other. A set of slide rail pulleys is rotatably connected to the inner side of the lower roller fixing frame, and the slide rail pulleys abut against the side of the vertical slide rail at the corresponding position near the movable support.

[0008] As a further improvement of this utility model, the two ends of the first spring are fixedly connected to the outer sides of the two ends of the first damping rod, respectively.

[0009] As a further improvement of this utility model, each of the two ends of the intermediate connecting seat is rotatably connected to a first damping rod.

[0010] As a further embodiment of this utility model: the bottom of the second damping rod is fixedly connected to the lower fixed plate, the movable end of the second damping rod is fixedly connected to the intermediate connecting seat, and the two ends of the second spring are respectively fixedly connected to the upper part of the lower fixed plate and the lower part of the intermediate connecting seat.

[0011] As a further embodiment of this utility model: the upper support plate is fixedly connected to a set of lower metal support plates. When the second spring and the first spring are not subjected to external force and naturally extend, the movable end of the second damping rod is in its shortest extended state, and the movable end of the second spring is in its longest extended state.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this invention, the impact force of the high-speed descent of the lifting platform is first absorbed by the buffer sponge layer, and then transmitted to the upper support plate through the metal support plate, driving the intermediate connecting seat to move downward. This movement simultaneously causes the first damping rods on both sides to rotate, stretching the first spring and consuming energy. At the same time, it directly compresses the second spring and forces the second damping rod to retract, generating stronger damping. The deformation of the two-stage springs and the two-stage damping work together to efficiently absorb and dissipate the impact, maximizing the safety of the lifting platform, personnel, and goods.

[0022] Reference Figures 1 to 5In this embodiment of the present invention, an attached cabin elevator includes: a lower support platform 1, a wall-mounted bracket 2 fixedly connected above the lower support platform 1, two sets of vertical slide rails 3 fixedly connected to the side of the wall-mounted bracket 2, a drive mechanism 4 fixedly connected above the wall-mounted bracket 2, a connecting chain 5 disposed below the drive mechanism 4, a first connecting hook 6 fixedly connected to the other end of the connecting chain 5, a loading step 7 fixedly connected above the lower support platform 1, a lifting platform 8 disposed above the lower support platform 1, a movable bracket 9 fixedly connected above the lifting platform 8, a second connecting hook 10 fixedly connected above the movable bracket 9, the second connecting hook 10 being adapted to the first connecting hook 6, and the second connecting hook 10 and the first connecting hook 6 having an annular buckle. The movable bracket 9 is symmetrically fixed with two sets of upper roller fixing frames 11 on one side near the wall-mounted bracket 2, and two sets of lower roller fixing frames 12 on the same side. Slide rails 13 are rotatably connected to the inner sides of both the upper roller fixing frames 11 and the lower roller fixing frames 12. The slide rails 13 are adapted to the vertical slide rails 3. Two sets of slide rails 13 are rotatably connected to the inner side of the upper roller fixing frames 11, and the two sets of slide rails 13 are pressed against the sides of the vertical slide rails 3 at corresponding positions. A set of slide rails 13 is rotatably connected to the inner side of the lower roller fixing frames 12, and the slide rails 13 are pressed against the side of the vertical slide rails 3 near the movable bracket 9 at the corresponding position.

[0023] A buffer sponge layer 14 is provided on the inner side of the lower support platform 1 below the lifting platform 8. Metal support plates 15 are fixedly connected to the upper and lower ends of the buffer sponge layer 14. A lower fixing plate 16 is fixedly connected to the upper part of the inner bottom wall of the lower support platform 1. Several sets of connecting rod rotating seats 17 are fixedly connected to the upper part of the lower fixing plate 16. A first damping rod 18 is rotatably connected to the inner side of the connecting rod rotating seat 17. A first spring 19 is sleeved on the outer side of the first damping rod 18. The two ends of the first spring 19 are fixedly connected to the outer ends of the two ends of the first damping rod 18, respectively. An intermediate connecting seat 20 is rotatably connected to the other end of the first damping rod 18. A set of first damping rods 18 is rotatably connected to both ends of each set of intermediate connecting seats 20.

[0024] A second damping rod 22 is fixedly connected between the intermediate connecting seat 20 and the lower fixed plate 16. A second spring 23 is sleeved on the outer side of the second damping rod 22. The bottom of the second damping rod 22 is fixedly connected to the lower fixed plate 16. The movable end of the second damping rod 22 is fixedly connected to the intermediate connecting seat 20. The two ends of the second spring 23 are fixedly connected to the upper part of the lower fixed plate 16 and the lower part of the intermediate connecting seat 20, respectively. An upper support plate 21 is fixedly connected to the upper part of the intermediate connecting seat 20. The upper support plate 21 is fixedly connected to a set of lower metal support plates 15. When the second spring 23 and the first spring 19 are naturally extended without being subjected to external force, the movable end of the second damping rod 22 is in its shortest extended state, and the movable end of the second spring 23 is in its longest extended state.

[0025] The working principle of this utility model is as follows: The lower support platform 1 is placed and fixed as a basic base; the wall-mounted bracket 2 fixedly connected above it is attached to the target wall to provide main support; two sets of vertical slide rails 3 fixedly installed on the side of the wall-mounted bracket 2 provide vertical guide rails. The drive mechanism 4 is fixed above the wall-mounted bracket 2, and its drive connecting chain 5 is extended and retracted, with a first connecting hook 6 fixed at the end of the connecting chain 5. The lifting platform 8 is set above the lower support platform 1 to bear the load; a second connecting hook 10 is installed on the movable bracket 9 fixed at its top, and the second connecting hook 10 is connected to the first connecting hook 6 through the ring buckle, so that the drive mechanism 4 can pull or lower the lifting platform 8.

[0026] During the lifting process, the upper roller fixing frame 11 and the lower roller fixing frame 12, which are fixedly connected to the wall side of the movable support 9, play a guiding and stabilizing role respectively: the two sets of slide rails 13 in the upper roller fixing frame 11 clamp the two sides of the vertical slide rail 3 to prevent shaking; the set of slide rails 13 in the lower roller fixing frame 12 presses against the inner side of the vertical slide rail 3 (facing the lifting platform 8) to resist overturning force, and all the pulleys roll along the vertical slide rail 3 to ensure smooth lifting;

[0027] A buffer sponge layer 14 is provided below the lowest position of the lifting platform 8 inside the lower support platform 1. Metal support plates 15 are fixed at the upper and lower ends of the layer to increase strength. When the lifting platform 8 descends too quickly, the impact force is transmitted through the lower part of the lifting platform 8 to the buffer sponge layer 14 and the bottom metal support plate 15, and then acts on the upper support plate 21 and the intermediate connecting seat 20 fixed below it.

[0028] The impact force drives the intermediate connecting seat 20 to move downward. On the one hand, this movement is transmitted through the first damping rod 18 (rotating around the connecting rod rotating seat 17) rotatably connected to both ends of the intermediate connecting seat 20, pulling the first spring 19 sleeved on the first damping rod 18, while the first damping rod 18 internally damps and dissipates energy. On the other hand, this movement directly compresses the second spring 23 between the intermediate connecting seat 20 and the lower fixed plate 16, and compresses the movable end of the second damping rod 22 fixed between the two, generating a second level of damping. The elastic forces of the first spring 19 and the second spring 23, together with the first damping rod 18 and the second damping rod 22, work together to absorb and dissipate the impact energy, ensuring the stability and safety of personnel or goods above the lifting platform 8.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
