Abstract
Description
Technical Field
[0001] This utility model relates to the field of lifting equipment technology, and in particular to a lifting device. Background Technology
[0002] In industrial sectors such as new energy PACK production and enclosure manufacturing, lifting mechanisms serve as core tooling equipment in material handling, assembly, and positioning processes. Their performance stability, cost-effectiveness, and operational flexibility directly impact a company's production efficiency and market competitiveness. Currently, the new energy PACK industry has entered a stage of fierce market competition, with cost reduction and efficiency improvement becoming core demands for companies to optimize operations. However, traditional lifting mechanism designs are no longer adequate to meet this core requirement. Specifically, traditional lifting mechanisms generally use square steel or aluminum as core structural materials, both of which have significant drawbacks. While square steel can meet the required support strength, its substantial weight increases the complexity of processing and welding, raises transportation and on-site installation costs, and the integrated welded base structure cannot be flexibly disassembled according to available space, resulting in poor adaptability. While aluminum offers lightweight advantages, its unit price is significantly higher than conventional metals, directly leading to a higher overall equipment cost, fundamentally contradicting the company's cost reduction goal of "controlling material costs." Utility Model Content
[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a lifting device that ensures support stability while controlling material and manufacturing costs, and solves the problems of high material cost, insufficient strength and inconvenience of disassembly and assembly of traditional lifting mechanisms.
[0004] To solve the above-mentioned technical problems, the present invention provides a lifting device, including a base and a supporting mechanism. The supporting mechanism is disposed on the base and includes a first support plate that can be raised and lowered relative to the base and a second support plate disposed on the first support plate that can rotate relative to the first support plate. The base includes a support and a platform. The support is composed of several branch pipes, which are detachably connected by connecting buckles. The platform is detachably disposed on the upper end of the support for mounting the supporting mechanism.
[0005] Furthermore, the support includes a horizontal portion for connecting the platform, a support portion for supporting the horizontal portion, and a reinforcing portion disposed between the horizontal portion and the support portion.
[0006] Furthermore, the horizontal section includes four first branch pipes connected end to end in sequence. Each pair of first branch pipes is detachably connected by the connecting buckle. The connecting buckle includes a hollow first cylinder and a second cylinder disposed on the outer periphery of the first cylinder. The first cylinder and the two second cylinders are perpendicular to each other. The two first branch pipes are respectively inserted into the first cylinder and one of the second cylinders. The other second cylinder is used to connect to the support section.
[0007] Furthermore, the support portion includes four vertical second branch pipes corresponding one-to-one with the four end corners of the horizontal portion, and each second branch pipe is inserted into a second cylinder of one of the connecting buckles.
[0008] Furthermore, the reinforcing part includes a third branch pipe horizontally disposed between two opposing first branch pipes. The two ends of the third branch pipe are respectively connected to the two corresponding first branch pipes through two connecting buckles. A vertical fourth branch pipe is also connected to the connection between the third branch pipe and the first branch pipe through a corresponding connecting buckle.
[0009] Furthermore, the reinforcing part also includes a fifth branch pipe horizontally disposed between each adjacent second branch pipe and the fourth branch pipe, and both ends of each fifth branch pipe are connected to the corresponding second branch pipe or the fourth branch pipe through the connecting buckle.
[0010] Furthermore, each of the second cylinders has a slot along its axial direction on its sidewall, the slot extending through the second cylinder to the side away from the first cylinder, and each of the second cylinders has a protrusion inside to allow the branch pipe inserted into the second cylinder to be interference-fitted with the second cylinder, and each of the second cylinders also has a screw hole to allow it to be connected to the branch pipe or platform by bolts.
[0011] Furthermore, a plurality of cylinders are provided at the lower end of the platform, and the output shafts of the cylinders extend upward through the platform and outward. The first support plate is provided at the upper end of the output shafts of the plurality of cylinders.
[0012] Furthermore, the first pallet has a first protruding post protruding upward in the middle, and the second pallet has a second protruding post protruding downward in the middle corresponding to the position of the first protruding post. The second protruding post is rotatably connected to the first protruding post on the same axis. The lower end of the second pallet is also provided with a plurality of casters, and the lower ends of the casters are in rolling contact with the upper surface of the first pallet.
[0013] Furthermore, the branch pipe is made of lean pipe.
[0014] The lifting device of this utility model has at least the following beneficial effects: The core structural branch pipe uses lean pipe instead of traditional high-cost aluminum or high-processing-fee square steel, directly reducing material procurement and customization costs. Simultaneously, each branch pipe of the base is detachably connected via a connecting buckle with built-in protrusions (achieving an interference fit with the branch pipe) and threaded holes (for bolt reinforcement). The platform and support are also detachable, allowing for disassembly to reduce volume and logistics costs during transportation. On-site installation requires no welding for rapid deployment. If a branch pipe or connecting buckle is damaged later, only the individual component needs to be replaced, not the entire system, significantly reducing disassembly, transportation, and maintenance costs. Furthermore, branch pipes can be added or removed to achieve flexible size adjustment. The support adopts a composite three-dimensional structure of "horizontal part + support part + reinforcing part," combined with the double fixing of the connecting buckle and the stable support of the legs, effectively compensating for the inherent strength of the lean pipe. The shortcomings are addressed to ensure overall support stability. In the top support mechanism, the cylinder-driven first support plate can precisely adjust the material height to adapt to different assembly processes. The second support plate is rotatably connected to the first support plate via a convex column coaxial with it. The universal wheels at its lower end can not only bear the weight of itself and the material, avoiding overload damage to the convex column connection, but also reduce rotational friction, allowing the second support plate to rotate easily and facilitating the adjustment of the material angle. At the same time, the second support plate is equipped with parallel rails and rollers, and convex edges on both sides of the lateral side, which not only facilitates the rapid transfer of materials between devices, but also prevents materials from slipping and ensures safety. In addition, the detachable structure allows for flexible adjustment of the support size according to the site space. The four sets of support legs can be independently fine-tuned in height to adapt to uneven ground, further improving the adaptability of the scene. Overall, it meets the industry's core requirements for lifting devices in terms of cost control, support stability, flexible operation, and multi-scene adaptability. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings.
[0022] Please refer to Figure 1 The lifting device of this utility model includes a base 1 and a top support mechanism 2. The top support mechanism 2 is disposed on the base 1 for lifting materials. The base 1 includes a support 11 and a platform 13. The support 11 is composed of several branch pipes (for ease of clear description of the structure of the support 11, the branch pipes at different positions are named as first branch pipe 1111, second branch pipe 1121, etc. below), and all branch pipes are made of lean pipe. The several branch pipes are detachably connected by connecting buckles 12. The platform 13 is detachably disposed on the upper end of the support 11 for mounting the top support mechanism 2.
[0023] Please refer to Figure 2 The connecting buckle 12 includes a hollow first cylindrical body 121 and two second cylindrical bodies 122 disposed on the outer periphery of the first cylindrical body 121. The first cylindrical body 121 and the two second cylindrical bodies 122 are perpendicular to each other. Each second cylindrical body 122 is formed by extending the side wall of the first cylindrical body 121 in the radial direction. Each side wall of the second cylindrical body 122 has an axially oriented slot 123, which penetrates the second cylindrical body 122 to the side away from the first cylindrical body 121. There are two slots 123 on each second cylindrical body 122, and the two slots 123 on each second cylindrical body 122 are symmetrically arranged on the side wall of the second cylindrical body 122 so that the second cylindrical body 122 is divided into two halves, which makes it easier for the branch pipe to be inserted. Each of the second cylindrical bodies 122 has a protruding protrusion 124 on its inner wall. The protrusion 124 is formed to protrude radially from the second cylindrical body 122. There are two protrusions 124 in each second cylindrical body 122, and the two protrusions 124 are symmetrically arranged. The arrangement of the protrusions 124 allows the branch pipe inserted into the second cylindrical body 122 to be interference-fitted with the second cylindrical body 122. Each of the second cylindrical bodies 122 also has a screw hole 125, so that the second cylindrical body 122 can be connected to the corresponding branch pipe and the platform 13 by bolts.
[0024] Please refer to Figure 3 The support 11 includes a horizontal portion 111 for connecting the platform 13, a support portion 112 for supporting the horizontal portion 111, and a reinforcing portion 113 disposed between the horizontal portion 111 and the support portion 112. The horizontal portion 111 includes four first branch pipes 1111 connected end-to-end, and each pair of first branch pipes 1111 is detachably connected by a connecting buckle 12. For example, one first branch pipe 1111 is inserted into the first cylinder 121, making one second cylinder 122 horizontal and the other second cylinder 122 vertical. Another first branch pipe 1111 adjacent to the first branch pipe 1111 is inserted into the horizontal second cylinder 122. Each first branch pipe 1111 is sequentially connected such that one end is inserted into a first cylinder 121 with a connecting buckle 12 and the other end is inserted into a second cylinder 122 with another connecting buckle 12. The platform 13 is horizontally disposed on the upper end of the four first branch pipes 1111 and the four connecting buckles 12, and is detachably connected to the connecting buckles 12 by bolts.
[0025] The support portion 112 includes four vertical second branch pipes 1121 corresponding to the four corners of the horizontal portion 111 to bear the weight at the four corners of the support 11. Each second branch pipe 1121 is inserted into a second cylinder 122 that connects the four first branch pipes 1111. Each second branch pipe 1121 is also screwed with a support foot 114 at its lower end. The diameter of the lower end of the support foot 114 is larger than the diameter of the second branch pipe 1121 to make the base 1 more stable.
[0026] The reinforcing part 113 includes a third branch pipe 1131 horizontally disposed between two opposing first branch pipes 1111. Both ends of the third branch pipe 1131 are connected to the corresponding two first branch pipes 1111 via two connecting buckles 12. For example, the number of third branch pipes 1131 is configured as a plurality of spaced-apart ones, with the end of each third branch pipe 1131 inserted into one of the second cylindrical bodies 122 of a connecting buckle 12. The first cylindrical bodies 121 of the connecting ports at both ends of the third branch pipe 1131 are sleeved around the outer periphery of the corresponding first branch pipe 1111, thereby connecting the third branch pipe 1131 to the first branch pipe 1111. The connecting buckle 12 connecting the third branch pipe 1131 and the first branch pipe 1111 has a spare second cylinder 122. The second cylinder 122 is used to clamp the vertical fourth branch pipe 1132. Each fourth branch pipe 1132 is also screwed with a support foot 114 at its lower end to cooperate with the support foot 114 at the lower end of the second branch pipe 1121 to make the base 1 more stable.
[0027] The reinforcing part 113 further includes a fifth branch pipe 1133 horizontally disposed between each adjacent second branch pipe 1121 and fourth branch pipe 1132. Both ends of each fifth branch pipe 1133 are connected to the corresponding second branch pipe 1121 or fourth branch pipe 1132 via the connecting buckle 12. For example, each second branch pipe 1121 and fourth branch pipe 1132 is provided with a connecting buckle 12, and the first cylindrical body 121 of the connecting buckle 12 is sleeved on the second branch pipe 1121 and the fourth branch pipe 1132. The two second cylindrical bodies 122 of the connecting buckle 12 are respectively oriented towards the second branch pipe 1121 or fourth branch pipe 1132 adjacent to the second branch pipe 1121 or fourth branch pipe 1132 connected to it. The fifth branch pipe 1133 is arranged laterally, and its two ends are respectively inserted into the second cylindrical bodies 122 of the two connecting buckles 12.
[0028] Please refer to Figure 4 and Figure 5 The top support mechanism 2 includes a first support plate 21 that can be raised and lowered relative to the base 1, and a second support plate 22 that is mounted on the first support plate 21 and can rotate relative to the first support plate 21. A plurality of cylinders 23 are provided at the lower end of the platform 13. Each cylinder 23 is detachably connected to the platform 13 by bolts. The output shaft of each cylinder 23 extends upward through the platform 13. The first support plate 21 is located on the upper end of the output shaft of the plurality of cylinders 23. A first protruding post 24 protrudes upward from the center of the first support plate 21. The second support plate 22 is located above the first support plate 21, and a second protruding post 25 protrudes downward from the center of the second support plate 22 corresponding to the position of the first protruding post 24. The second protruding post 25 is rotatably connected to the first protruding post 24 coaxially. A plurality of casters 26 are also provided at the lower end of the second support plate 22, and the lower ends of the casters 26 roll in contact with the upper surface of the first support plate 21. The advantages of providing casters 26 are as follows: Firstly, they fill the gap between the first support plate 21 and the second support plate 22 formed by the first protrusion 24 and the second protrusion 25, preventing the entire weight of the second support plate 22 from being borne by the connection between the first protrusion 24 and the second protrusion 25. This protects the core rotating structure of the first protrusion 24 and the second protrusion 25 from damage due to overload. Simultaneously, after the casters 26 bear most of the weight of the second support plate 22 and the items it supports, the rotational friction between the first protrusion 24 and the second protrusion 25 is significantly reduced, making the rotation of the second support plate 22 smoother and easier to achieve by hand, thus extending the service life of the first protrusion 24 and the second protrusion 25.
[0029] The second pallet 22 is also provided with two parallel tracks 27 along its length. Each track 27 is provided with several rollers 28, and the axial direction of each roller 28 is the width direction of the track 27. The rollers 28 are evenly distributed along the length of the track 27, thus replacing sliding friction with rolling friction, which facilitates the user to move the product between devices. The second pallet 22 also has protruding flanges 29 on both its lateral sides along its length. These flanges are higher than the tracks 27 and the rollers 28 to protect the product on the second pallet 22.
[0030] One embodiment of the lifting device of this utility model operates as follows: In use, the material is placed on several rollers 28 on the second pallet 22. The angle of the material can be adjusted by rotating the second pallet 22, and the height of the second pallet 22 can be adjusted by the cylinder 23. By placing several lifting devices in sequence, the material can also be easily transferred through several tracks 27 and rollers 28.
[0031] Compared with existing technologies, the lifting device of this utility model achieves multiple beneficial effects through material optimization and structural innovation: the core structural branch pipe uses lean pipe instead of traditional high-cost aluminum or high-processing-fee square steel, directly reducing material procurement and customization costs. Meanwhile, each branch pipe of the base is detachably connected via a connecting buckle with built-in protrusions (achieving an interference fit with the branch pipe) and screw holes (for bolt reinforcement). The platform and support are also detachable, allowing for disassembly to reduce volume and logistics costs during transportation. On-site installation requires no welding for rapid deployment. If a branch pipe or connecting buckle is damaged later, only the individual component needs to be replaced, not the entire system, significantly reducing disassembly, transportation, and maintenance costs. The support adopts a composite three-dimensional structure of "horizontal part + support part + reinforcement part," which, combined with the double fixing of the connecting buckle and the stable support of the legs, effectively compensates for the inherent strength of the lean pipe. The shortcomings are addressed to ensure overall support stability. In the top support mechanism, the cylinder-driven first support plate can precisely adjust the material height to adapt to different assembly processes. The second support plate is rotatably connected to the first support plate via a convex column coaxial with it. The universal wheels at its lower end can not only bear the weight of itself and the material, avoiding overload damage to the convex column connection, but also reduce rotational friction, allowing the second support plate to rotate easily and facilitating the adjustment of the material angle. At the same time, the second support plate is equipped with parallel rails and rollers, and convex edges on both sides of the lateral side, which not only facilitates the rapid transfer of materials between devices, but also prevents materials from slipping and ensures safety. In addition, the detachable structure allows for flexible adjustment of the support size according to the site space. The four sets of support legs can be independently fine-tuned in height to adapt to uneven ground, further improving the adaptability of the scene. Overall, it meets the industry's core requirements for lifting devices in terms of cost control, support stability, flexible operation, and multi-scene adaptability.
[0032] The above embodiments only illustrate preferred implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
