Description

Technical Field

[0001] This utility model relates to the field of aerial work equipment technology, and in particular to an auxiliary lifting device for aerial work. Background Technology

[0002] In the field of large equipment installation, it is often necessary to precisely install heavy or large-sized parts to target locations at high altitudes or in confined spaces.

[0003] Traditional operating methods primarily rely on two technologies: overhead crane lifting and forklift lifting. However, both have significant limitations under complex working conditions. Specifically, for overhead crane lifting, the crane's operation depends on the overhead rail or beam structure, requiring unobstructed straight-line movement space above the work area. However, in scenarios such as inside petrochemical reaction towers, underground pipe corridors, or converted plants, there are often pipes, support frames, or existing equipment above, making it impossible for the crane to pass. For forklift lifting, although forklifts can vertically lift components using their forks, their degree of freedom of movement is limited to the Z-axis direction. When components need to translate along the X / Y axes or rotate around the Z-axis in the horizontal plane, manual pushing or pulling or auxiliary equipment must be used, which can easily cause the components to sway or even tip over. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide an auxiliary lifting device for high-altitude operations, which can realize multi-degree-of-freedom position adjustment and meet the requirements of lifting and installing high-altitude operations in a relatively small space.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides an auxiliary lifting device for high-altitude operations, including a main frame, a bracket, a lifting mechanism, and a translation and rotation device. The bracket is movably mounted on the main frame, and the lifting mechanism is located between the main frame and the bracket. The lifting mechanism includes a telescopic device and a traction member. The telescopic device is kinetically connected to the traction member, and one end of the traction member is connected to the bracket. The translation and rotation device is located on the main frame and is used to drive the main frame to translate in the X and Y axis directions and rotate around the Z axis. When the telescopic device is in working condition, the end of the traction member connected to the bracket moves up and down.

[0006] In addition, the high-altitude operation auxiliary lifting device according to the present invention may also have the following additional technical features: Furthermore, the traction component is a rope.

[0007] Furthermore, the cable is a flexible cable, and the end of the cable away from the bracket is connected to the main frame.

[0008] Furthermore, a turntable is rotatably connected to the telescopic end of the telescopic device, and the rope is wound around the turntable.

[0009] Furthermore, the cable is provided with multiple ropes, which are arranged in parallel.

[0010] Furthermore, the main frame has vertically arranged grooves at opposite ends, and the bracket has sliding parts at corresponding ends, with the sliding parts slidably disposed within the grooves.

[0011] Furthermore, the sliding part includes a first rotating shaft and a first roller. One end of the first rotating shaft is fixed to the bracket, and the first roller is rotatably disposed at the other end of the first rotating shaft. The diameter of the first roller is adapted to the width of the sliding groove.

[0012] Furthermore, a vertical plane is provided on the main frame, and rolling parts are provided at both ends of the bracket, with the rolling parts rolling on the vertical plane.

[0013] Furthermore, the rolling part includes a second rotating shaft and a second roller, one end of the second rotating shaft is fixed on the bracket, and the second roller is rotatably disposed at the other end of the second rotating shaft.

[0014] Furthermore, the translation and rotation device includes multiple casters.

[0015] The beneficial effects of this utility model include at least the following: when the telescopic device is in working condition, the telescopic end of the telescopic device drives the end of the traction member connected to the bracket to move up and down, thereby realizing the function of raising and lowering the bracket. When the translation and rotation device 400 is in working condition, the main frame can translate in the X and Y axis directions, and can also rotate around the Z axis, thereby realizing the function of translating the bracket in any direction in the horizontal plane, and simultaneously realizing the function of rotating the bracket around the Z axis. Compared with the prior art, the high-altitude operation auxiliary lifting device in this application can realize multi-degree-of-freedom position adjustment at the same time, and the bracket is raised relative to the bottom of the main frame, which has lower requirements for the space above the working area, thus meeting the requirements of lifting and installing high-altitude operations in a relatively small space.

[0020] Specifically, please refer to Figures 1 to 4This utility model provides an auxiliary lifting device for high-altitude operations, comprising a main frame 100, a bracket 200, a lifting mechanism 300, and a translation and rotation device 400. The bracket 200 is movably mounted on the main frame 100, meaning it can move relative to the main frame 100. The main frame 100 provides support, while the bracket 200 serves to hold parts. For example, a corresponding mounting bracket 210 can be first installed on the bracket 200, and then the parts can be fixed to the mounting bracket 210 to improve the stability of parts transportation. The lifting mechanism 300 is located between the main frame 100 and the bracket 200, and is used to lift the bracket 200, thereby causing the bracket 200 to move up and down relative to the main frame 100. Specifically, the lifting mechanism 300 includes a telescopic device 310 and a traction member 320. The fixed end of the telescopic device 310 is fixed to the main frame 100, and the telescopic end of the telescopic device 310 is connected to the traction member 320 via a transmission connection. One end of the traction member 320 is connected to the bracket 200, and the translation and rotation device 400 is mounted on the main frame 100. Optionally, the telescopic device 310 can be a telescopic motor, a telescopic cylinder, a telescopic hydraulic cylinder, or other similar devices.

[0021] In this embodiment, when the telescopic device 310 is in operation, the telescopic end of the telescopic device 310 drives the end of the traction member 320 connected to the bracket 200 to move up and down, thereby realizing the function of raising and lowering the bracket 200. When the translation and rotation device 400 is in operation, the main frame 100 can translate in the X and Y axis directions and rotate around the Z axis, thereby realizing the function of translating the bracket 200 in any direction in the horizontal plane, and at the same time realizing the function of rotating the bracket 200 around the Z axis.

[0022] In some alternative embodiments, such as Figure 1 , Figure 3 As shown, the traction component 320 is a rope. One end of the rope is fixed to the telescopic end of the telescopic device 310, and the other end of the rope is fixed to the bracket 200. When the telescopic end of the telescopic device 310 extends and retracts, the bracket 200 will also move up and down with the telescopic end of the telescopic device 310 because the length of the rope is fixed.

[0023] In some alternative embodiments, such as Figure 1 , Figure 3As shown, the cable is a flexible cable, which facilitates the installation of both ends of the cable at a lower position and also makes it convenient to replace and carry the cable. During installation, one end of the flexible cable is connected to the main frame 100, and the other end is connected to the bracket 200. The middle section of the flexible cable is movably mounted on the telescopic end of the telescopic device 310. When the telescopic end of the telescopic device 310 extends or retracts, because the length of the cable is fixed and its middle section is limited on the telescopic end of the telescopic device 310, the bracket 200 will also move up and down along with the telescopic end of the telescopic device 310.

[0024] In some alternative embodiments, such as Figure 3 As shown, a turntable 311 is rotatably connected to the telescopic end of the telescopic device 310, and a rope is wound around the turntable 311. When the telescopic end of the telescopic device 310 extends or retracts, since the length of the rope is fixed and its middle is limited on the turntable 311, the bracket 200 will also move up and down with the telescopic end of the telescopic device 310, and the rope will drive the turntable 311 to rotate.

[0025] In this embodiment, during the lifting and lowering process of the bracket 200, the rope wrapped around the turntable 311 can make the force on the bracket 200 more even, reduce swaying and swinging, improve the stability of lifting and lowering, reduce safety risks, and at the same time, the rope is less likely to get stuck with the telescopic device 310, so that the bracket 200 can move up and down smoothly.

[0026] In some optional embodiments, to further improve the stability of the lifting and lowering, such as Figure 1 , Figure 3 As shown, multiple ropes are provided, arranged in parallel. Correspondingly, a corresponding number of turntables 311 can be set, or a corresponding number of grooves matching the diameter of the ropes can be set on the turntables 311. In this embodiment, during the lifting and lowering process of the bracket 200, the multiple ropes wound around the turntables 311 can make the force on the bracket 200 more even, reduce swaying and swinging, improve the stability of lifting and lowering safety risks.

[0027] In some alternative embodiments, such as Figure 2 As shown, the main frame 100 has vertically arranged grooves 110 at both ends, and the bracket 200 has corresponding sliding parts 220 at its left and right ends, which slide within the grooves 110. Thus, when the lifting mechanism 300 drives the bracket 200 to rise or fall, the sliding parts 220 on the bracket 200 can slide within the grooves 110, thus limiting the movement of the bracket 200 and making the lifting process of the bracket 200 smoother.

[0028] In some alternative embodiments, such as Figure 2As shown, the sliding part 220 includes a first rotating shaft 221 and a first roller 222. One end of the first rotating shaft 221 is fixedly mounted on the bracket 200, and the first roller 222 is rotatably mounted on the other end of the first rotating shaft 221. The diameter of the first roller 222 is adapted to the width of the slide groove 110. Thus, when the lifting mechanism 300 drives the bracket 200 to rise or fall, the first roller 222 can roll within the slide groove 110, allowing the bracket 200 to move smoothly up and down. Simultaneously, the first roller 222 is fully engaged within the slide groove 110, serving to limit the movement of the bracket 200 and making the lifting process of the bracket 200 more stable.

[0029] In some alternative embodiments, to enable the bracket 200 to rise and fall more smoothly, such as Figure 4 As shown, a vertical plane 120 is provided at both the left and right ends of the main frame 100, and a rolling part 230 is provided at the corresponding positions at the left and right ends of the lower part of the bracket 200. The rolling part 230 is rolled on the vertical plane 120. In this way, when the lifting mechanism 300 drives the bracket 200 to lift and lower, the rolling part 230 at the lower part of the bracket 200 can roll on the vertical plane 120, so that the bracket 200 can move up and down smoothly and ensure that the lifting and lowering process of the bracket 200 is more stable.

[0030] In some alternative embodiments, such as Figure 4 As shown, the rolling part 230 includes a second rotating shaft 231 and a second roller 232. One end of the second rotating shaft 231 is fixed to the bracket 200, and the second roller 232 is rotatably mounted on the other end of the second rotating shaft 231. Thus, when the lifting mechanism 300 drives the bracket 200 to lift or lower, the second roller 232 rotatably mounted on the bracket 200 can roll on the vertical plane 120, allowing the bracket 200 to move smoothly up and down, making the lifting process of the bracket 200 more stable.

[0031] In some alternative embodiments, such as Figure 1 , Figure 3 As shown, the translation and rotation device 400 includes multiple casters. These casters allow the main frame 100 to translate along the X and Y axes and rotate around the Z axis, thus enabling the carriage 200 to translate in any direction within the horizontal plane and rotate around the Z axis. Optionally, the casters can be passive casters, which have no power source but can move and turn using external pushing or pulling forces. Alternatively, self-driving casters can be selected, which have a built-in drive device, such as a motor, that generates its own power and can move and turn autonomously without continuous external power.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0033] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of protection of this utility model. 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 scope of protection of this utility model.
