Abstract
Description
Technical Field
[0001] This utility model relates to the field of elevator transportation technology, specifically to an elevator structural component transportation device. Background Technology
[0002] An elevator is a vertical transportation device that transports people or goods. Because elevator structural components are large in size, special transportation devices are required for installation and handling. When transporting large elevator structural components, the transportation device itself occupies a lot of space, and the size of the transportation device is not easy to adjust. Therefore, it is inconvenient to use when transporting elevator structural components to relatively narrow transportation locations.
[0003] Secondly, existing elevator structural component transport devices that transport large-volume components occupy excessive storage space when stored due to factors such as unreasonable structural design or space utilization. This not only increases the cost of storage sites but also brings greater difficulties to storage management.
[0004] Meanwhile, traditional transportation methods generally use flatbed trucks, forklifts, or handling vehicles, which are simple in structure. After arriving at the designated test site, unloading and handling are still required, which is time-consuming, labor-intensive, and inefficient. Utility Model Content
[0005] One objective of this utility model is to provide an elevator structural component transportation device, which adjusts the distance between the first and last bottom plates through a first telescopic mechanism, so that the structure can fit the elevator structural component and facilitate passage through relatively narrow transportation locations.
[0006] Existing elevator structural component transport devices generally consist of a base plate and pulleys mounted on it. When transporting large elevator structural components, a larger transport device is required. However, in confined spaces, the larger device itself is too bulky to move and pass flexibly. The base plate of existing elevator structural component transport devices is typically a single piece of plate, which does not fit the different sizes of elevator structural components well. When the elevator structural component is relatively small, an oversized base plate makes the transport device cumbersome in confined spaces, occupying too much space and increasing transport difficulty. When the elevator structural component is large, if the transport device is not well-fitted, the component may be unstable during transport, and the device itself may also have difficulty passing through confined spaces.
[0007] To address the aforementioned problems, this utility model proposes an elevator structural component transport device. The base plate includes a first base plate and a last base plate, with at least one intermediate base plate positioned between the first and last base plates. The intermediate base plate is interconnected with the first and last base plates to form a more stable structural system. This system can distribute the pressure from the goods and external impacts during transport, preventing deformation or damage to the transport device due to excessive local stress. For example, when transporting heavy elevator structural components, the intermediate base plate can evenly distribute the weight of the structural components to the various supporting parts of the transport device, enhancing the overall load-bearing capacity and stability of the device.
[0008] A first telescopic mechanism is provided between the first and last base plates. The first telescopic mechanism is used to adjust the distance between the first and last base plates. A sliding groove is provided on the first telescopic mechanism, and the middle base plate is connected to the sliding groove. The middle base plate can slide on the sliding groove. The first telescopic mechanism can adjust the distance between the first and last base plates, so that the size of the transport device base plate can be adjusted when transporting larger elevator structural components. After the elevator structural component is placed on the transport device, the first telescopic mechanism is adjusted to be slightly larger than the size of the elevator structural component, so that the elevator structural component can be stably placed on the transport device. When passing through narrow areas, the first telescopic mechanism is adjusted so that the transport device can fit the size of the elevator structural component. When turning and adjusting direction in narrow areas, it can be operated more flexibly, optimizes space utilization, and facilitates the transport of large elevator structural components through narrow areas.
[0009] Furthermore, the first telescopic mechanism can be of various telescopic structures. The preferred first telescopic mechanism of this invention includes a moving rod and a rotating rod. One end of the rotating rod is threaded into one end of the moving rod. The rotating rod can rotate axially on the first base plate. The rotating rod can be driven manually or by various rotational drive methods. Preferably, a motor is connected to the rotating rod. By driving the rotating rod axially through the motor, the moving rod threaded onto it will move forward or backward axially. The other end of the moving rod is fixedly connected to the last base plate, and the other end of the rotating rod is connected to the first base plate. The relative movement of the moving rod causes the last base plate to move closer to or further away from the first base plate, adjusting the distance between the first and last base plates. Furthermore, when elevator structural components are placed on the base plate, they exert pressure and other forces on the base plate. The rotating rod and moving rod passing through the base plate can directly transfer these forces from the stress area of the base plate to other structural components. In this way, the forces originally concentrated in a localized area of the base plate are dispersed throughout a larger structural system, improving the overall strength of the transportation device.
[0010] Furthermore, an adjustment assembly is provided between the first base plate and the adjacent intermediate base plate, between the adjacent intermediate base plates, and between the last base plate and the adjacent intermediate base plate. The adjustment assembly can take various forms; in this invention, the preferred adjustment assembly includes four connecting rods forming a quadrilateral, two fixed hinge joints, and two movable hinge joints. The two fixed hinge joints are located at one opposite corner of the quadrilateral, and the two movable hinge joints are located at the other opposite corner. The fixed hinge joints are located at the bottom of the first, last, or intermediate base plate. One end of the fixed hinge joint is fixed to the base plate, and the other end is connected to the movable hinge joint via a connecting rod. The movable hinge joint is connected to the fixed hinge joint via a connecting rod. When the distance between the first and last base plates changes, the interior angles of the quadrilateral change. This change in the interior angles leads to a change in the relative position between the base plates connected to the fixed hinge joints, thereby achieving distance adjustment.
[0011] Furthermore, the fixed hinge joint is located at one opposite corner of the quadrilateral and fixed to the bottom of the base plate, providing a relatively stable support point for the entire adjustment assembly. At the same time, the connecting rod itself has a certain rigidity, which can effectively transmit force. The two movable hinge joints are located at the other opposite corner, allowing the connected connecting rods to rotate at a certain angle. This rotational characteristic can play a buffering role during transportation. When an external force is applied to the adjustment assembly, the adjustment assembly can transfer the force from one component to another, so that the force can be evenly distributed throughout the structure, avoiding deformation or damage to the structure due to uneven force, thereby improving the stability and reliability of the entire structure.
[0012] Furthermore, the line where the fixed hinge joint is located is parallel to the extension and retraction direction of the first telescopic mechanism, and the line where the movable hinge joint of the same adjusting component is located is perpendicular to the extension and retraction direction of the first telescopic mechanism. The fixed hinge joint, the movable hinge joint, and the connecting rod cooperate with each other so that the movement direction of the base plate is consistent with the extension and retraction direction of the telescopic mechanism. This ensures that during the movement, the force applied by the telescopic mechanism acts directly on the movement direction of the base plate, avoiding lateral forces or torques caused by inconsistent directions, reducing wear and loosening between structural components, improving the stability and reliability of the entire device, and extending the service life of the equipment.
[0013] Furthermore, the elevator structural component transport device also includes a side plate, which comprises a fixed side plate and a movable side plate. The fixed side plate is connected to the first base plate, and the movable side plate is connected to the last base plate. A rotating shaft is provided at the connection between the movable side plate and the last base plate. The rotating shaft is used to drive the movable side plate to rotate. When loading the elevator structural component, one end of the movable side plate is locked at the bottom edge of the elevator structural component to be transported. The movable side plate surface connects the bottom of the elevator structural component and the bottom of the transport device, forming a surface for the sliding transport of the elevator structural component. This allows the elevator structural component to slide to the base plate area of the transport device via ball bearings. When unloading, the movable side plate is first rotated so that one end contacts the ground. By retracting the first telescopic mechanism, a pushing action is applied to the elevator structural component, causing the center of gravity of the elevator structural component to shift towards the movable side plate. Under the traction of gravity, the elevator structural component slides down the movable side plate surface, completing the unloading.
[0014] Furthermore, the movable side plate is equipped with ball bearings on the side closest to the fixed side plate, which reduces friction on the movable side plate, saving time and effort and improving loading and unloading efficiency.
[0015] Furthermore, a second telescopic mechanism is provided at the top of the movable side plate and the fixed side plate. The second telescopic mechanism includes a fixed column and a movable column. The movable column is fitted inside the fixed column and can slide along the axial direction of the fixed column within the fixed column. There are various ways to fix the movable column and the fixed column. In this utility model, the movable column and the fixed column are provided with mutually compatible bolt holes. By fixing with bolts, the second telescopic mechanism cooperates with the telescopic movement of the first telescopic mechanism. The second telescopic mechanism connects the top of the movable side plate and the fixed side plate. The connecting column can connect the fixed side plate and the movable side plate of the transport device to form a more stable overall structure. During transportation, especially when the transport device is subjected to bumps, vibrations or external impacts, the second telescopic mechanism can effectively disperse these external forces, reduce the stress borne by the side plate alone, and prevent the side plate from deforming, loosening or even falling off, thereby improving the overall stability and reliability of the transport device.
[0016] Furthermore, both the fixed side plate and the movable side plate are equipped with handles, and handles are provided on both sides, so that multiple people can work together to pull the elevator structural component transport device, which is more conducive to transporting elevator structural components with large weight and volume.
[0017] Furthermore, the pulleys are located at the bottom of the first, last, or middle base plate, and each base plate is provided with at least two pulleys. Two or more pulleys can form a more stable support structure, which can better support multiple base plates.
[0018] Compared with the prior art, the elevator structural component transportation device provided by this utility model has the following beneficial effects:
[0019] 1. The present invention provides an elevator structural component transportation device with an adjustment component and multiple telescopic mechanisms.

At the same time, it is easy to adjust the size of the transportation device to fit the elevator structural component, and has greater flexibility, which is beneficial for transporting elevator structural components to relatively narrow transportation locations.
[0020] 2. The elevator structural component transportation device of this utility model occupies little space when it is in a fully retracted state by adjusting the telescopic mechanism, which is also convenient for storage and management, and effectively improves the space utilization rate.

Detailed Implementation
[0030] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, where there is no conflict, the embodiments of this utility model and the features within them can be combined with each other.
[0031] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.
[0032] Example 1
[0033] like Figure 1 The elevator structural component transport device shown includes a base plate and casters 4 mounted on the base plate. The base plate includes a first base plate 1 and a last base plate 3. An intermediate base plate 2 is provided between the first base plate 1 and the last base plate 3. It should be noted that there may be multiple intermediate base plates 2.
[0034] like Figure 6 As shown, multiple intermediate base plates 2 can also be provided between the first base plate 1 and the last base plate 3; a first telescopic mechanism is provided between the first base plate 1 and the last base plate 3. The first telescopic mechanism is used to adjust the distance between the first base plate 1 and the last base plate 3, and to adjust the size of the transport device. The first telescopic mechanism includes a moving rod 16 and a rotating rod 15. One end of the rotating rod 15 is threaded into one end of the moving rod 16, and the other end of the moving rod 16 is fixedly connected to the last base plate 3. The other end of the rotating rod 15 is connected to the first base plate 1, and the rotating rod 15 can rotate axially on the first base plate 1; the motor 13 and the rotating rod 15 is connected, and the rotating rod 15 is driven by the motor 13 to rotate clockwise or counterclockwise. When the rotating rod 15 rotates clockwise, it drives the last bottom plate fixed at one end of the moving rod 16 to move away from the first bottom plate. When the rotating rod 15 rotates counterclockwise, it drives the last bottom plate fixed at one end of the moving rod 16 to move closer to the first bottom plate, thus adjusting the size of the transport device. The first telescopic mechanism is provided with a sliding groove 14, and the intermediate bottom plate 2 is connected to the sliding groove 14. The sliding groove 14 is installed on both sides of the horizontal plane axial direction of the telescopic mechanism, and the intermediate bottom plate 2 can slide on the sliding groove 14.
[0035] Example 2
[0036] Based on Example 1, such as Figure 1 and 3As shown, an adjustment assembly is provided between the first base plate 1 and the adjacent intermediate base plate 2, and between the adjacent intermediate base plates 2. An adjustment assembly is also provided between the last base plate 3 and the adjacent intermediate base plate 2. The adjustment assembly includes four connecting rods 19 connected in a quadrilateral, two fixed hinge joints 17, and two movable hinge joints 18. The two fixed hinge joints 17 are located at one opposite corner of the quadrilateral, and the two movable hinge joints 18 are located at the other opposite corner of the quadrilateral. The fixed hinge joints 17 are located at the bottom of the first base plate 1, the last base plate 3, or the intermediate base plate 2. The line where the fixed hinge joints 17 are located is parallel to the extension and retraction direction of the first telescopic mechanism, and the line where the movable hinge joints 18 of the same adjustment assembly are located is perpendicular to the extension and retraction direction of the first telescopic mechanism.
[0037] like Figure 1 As shown, when the rotating rod 15 drives the last base plate 3 fixed at one end of the moving rod 16 to move away from the first base plate 1 to the stretched state, the adjusting component also adjusts the sliding of the intermediate base plate 2 according to the mutual movement of the first base plate 1 and the last base plate 3. When stretched, the interior angle of the quadrilateral at the fixed hinge joint 17 becomes smaller, and the distance between the adjacent base plates connected by the fixed hinge joint 17 also becomes larger accordingly.
[0038] like Figure 3 As shown, when the rotating rod 15 drives the last base plate 3, which is fixed to one end of the moving rod 16, to move towards the first base plate 1 to the retracted state, the adjusting component also adjusts the sliding of the intermediate base plate 2 according to the mutual movement of the first base plate 1 and the last base plate 3. When retracted, the interior angle of the quadrilateral at the fixed hinge joint 17 becomes larger, and the distance between the adjacent base plates connected by the fixed hinge joint 17 also becomes smaller accordingly.
[0039] Example 3
[0040] Based on Examples 1 and 2, such as Figure 2 As shown, it also includes side plates, which include a fixed side plate 5 and a movable side plate 9. The fixed side plate 5 is connected to the first base plate 1, and the movable side plate 9 is connected to the last base plate 3. A rotating shaft 12 is provided at the connection between the movable side plate 9 and the last base plate 3. The rotating shaft 12 is used to drive the movable side plate 9 to rotate. Figure 5 As shown, the movable side plate 9 is provided with ball bearings 11 on the side near the fixed side plate 5. During loading and unloading, the movable side plate 9 can be opened to a suitable position and fixed by rotating the rotating shaft 12. At the same time, it can also adapt to the needs of various loading and unloading methods. For example, when loading and unloading with a forklift, the side plate can be opened to a suitable angle to facilitate forklift entry and exit; when handling manually, the position of the side plate can also be adjusted according to the actual situation to facilitate manual operation.
[0041] like Figure 4As shown, the movable side plate 9 and the fixed side plate 5 are provided with a second telescopic mechanism at their top. The second telescopic mechanism includes a fixed column 6 and a movable column 8. The movable column 8 is fitted inside the fixed column 6 and can slide along the axial direction of the fixed column 6 inside the fixed column 6. When the first telescopic structure moves, the second telescopic mechanism also cooperates with it. The movable column 8 and the fixed column 6 are provided with mutually compatible bolt holes. When the second telescopic mechanism moves to a position that is compatible with the size of the elevator structural component, it is fixed by bolts 7.
[0042] Both the fixed side plate 5 and the movable side plate 9 are equipped with two handles 10. When transporting large and heavy elevator structural components, two people can work together to move and transport them, improving transportation efficiency and avoiding situations where a single person is unable to push the object due to insufficient strength or pushes it too slowly. At the same time, when moving in narrow spaces, two people can coordinate the angle and force of the push to make the object smoothly bypass obstacles or enter the designated position, enhancing the flexibility and controllability of operation and improving safety.
[0043] like Figure 2 As shown, the casters 4 are located at the bottom of the first base plate 1, the last base plate 3, or the middle base plate 2. Each of the first base plate 1, the middle base plate 2, or the last base plate 3 is equipped with two casters 4. The two casters are distributed on each base plate, which can distribute the weight of the base plate and the objects on it to multiple casters. In this way, the load on each caster is relatively small, reducing the force on a single caster, improving the service life and reliability of the casters, and also reducing the pressure on the ground, avoiding damage to the ground. Multiple casters provide multiple support points, enhancing the stability of the entire device.
[0044] The implementation principle of the above embodiment is as follows: When the operator uses the device, they first start the motor 13 to adjust the overall size of the base plate covering the elevator structural component, making it slightly larger than the elevator structural component. The adjustment component ensures that the middle base plate 2 is evenly distributed with force, providing better support. During loading, one end of the movable side plate 9 can be clipped to the bottom edge of the elevator structural component to be transported, so that the movable side plate 9 forms a plane for transporting the elevator structural component. One side of the movable side plate 9 is provided with ball bearings 11, allowing the elevator structural component to slide to the base plate area of the transport device via the ball bearings 11. Then, the movable side plate 9 is retracted. When passing through narrow areas, the first and second telescopic mechanisms are further fine-tuned. This design optimizes space utilization by fitting the size of the elevator structural components, providing greater flexibility and facilitating the transport of larger elevator structural components through narrow areas. During unloading, one end of the movable side plate 9 can be placed on the ground, and by adjusting the motor 13, the first telescopic structure can be retracted, pushing the elevator structural component towards the movable side plate 9 and further sliding it down, making unloading more time-saving and labor-saving. In addition, when storing the transport device, adjusting the motor 13 allows the elevator transport device to be in a fully retracted state, significantly reducing space occupancy. This makes it suitable for storage and transportation in environments with limited space, making rational use of space resources and facilitating subsequent retrieval and management.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.
[0046] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope.
