[0032] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] As described in the background section, due to the large size and weight of vacuum suction cups, replacement and handling require the manual cooperation of multiple people, posing significant safety hazards during the handling process. For example, if one person loses their grip, causing the vacuum suction cup to become unstable and fall to the ground, it can cause injury or damage to the suction cup. Furthermore, vacuum suction cups require high precision, and prolonged manual contact operation can affect the precision of the vacuum suction cup, thereby impacting its adsorption effect.

[0034] Therefore, this application provides a hoisting mechanism, which aims to solve the technical problems in the prior art where manual handling of vacuum suction cups is difficult and easily causes damage to the vacuum suction cups.

[0035] The following analysis, in conjunction with the accompanying drawings, details a hoisting mechanism. Figures 1 to 4The mechanism includes: a support structure 10; a connecting structure 20, including a fixed frame 210, several fixed plates 220 surrounding the fixed frame 210, and several connecting cables 230, one end of the several connecting cables 230 converging at the same point and the other end connected to the fixed frame 210, the fixed frame 210 and the connecting cables 230 combined to make the connecting structure 20 conical in shape, the fixed frame 210 used to tension the connecting cables 230, one end of the fixed plate 220 extending toward the bottom surface of the fixed frame 210 to form a connecting part 2200, the connecting part 2200 being connected to the equipment 40 to be transported; and a displacement component 30, connected between the point where the several connecting cables 230 converge and the support structure 10, used to lift the equipment to be transported and transport it to a designated location.

[0036] In a specific embodiment, such as Figures 1 to 4 As shown, the connection structure 20 also includes a main connector 200, with one end of several connecting cables 230 converging at the same point and connected to the main connector 200, and the other end connected to the fixing plate 220. The displacement component is connected between the main connector 200 and the support structure 10.

[0037] The support structure 10 provides stable support for the connecting structure 20, displacement component 30, and the equipment 40 to be transported during hoisting operations, preventing the mechanism from tipping over due to excessive weight of the equipment 40. The connecting structure 20 connects the equipment 40 to the displacement component 30. Both ends of the main connecting member 200 are equipped with retaining rings. The displacement component 30 is connected to the retaining ring on one end of the main connecting member 200. One end of all the connecting cables 230 is connected to the fixing plate 220, and the other ends converge and are connected to the retaining ring on the other end of the main connecting member 200. The cooperation between the main connecting member 200, the fixing frame 210, the fixing plate 220, and the connecting cables 230 forms a stable conical structure. Even if the equipment 40 shakes during hoisting, the stability of the equipment's center of gravity is ensured, improving the safety of hoisting. The fixing frame 210 is used to install the fixing plate 220. When the connecting cable 230 is connected between the main connecting member 200 and the fixing plate 220, the fixing frame 210 has a certain weight, and the connecting cable 230 is tensioned under the weight, so that each connecting cable 230 can be fully utilized to provide tension to the equipment 40 to be transported. This ensures the stability of the center of gravity of the equipment 40 to be transported and avoids the situation where the connecting cable 230 is loose and cannot be tensioned, thus failing to provide effective tension to the equipment 40 to be transported, resulting in instability of the center of gravity of the equipment 40 to be transported and swaying during hoisting.

[0038] In one specific embodiment, a fixing member is provided at one end of the connecting cable 230, a first connecting hole is provided on the upper surface of the fixing frame 210, and a second connecting hole is provided on the top surface of the fixing plate 220. The fixing member passes through the second connecting hole and connects with the first connecting hole. The fixing member realizes the fixed connection between the fixing frame and the connecting cable, and at the same time realizes the limited installation of the fixing plate 220.

[0039] In one specific embodiment, the connecting structure 20 further includes several connecting buckles, and the two ends of the connecting cable 230 are connected to the buckle body of the main connector 200 and the fixing plate 220 through the connecting buckles to realize the detachable connection of the connecting cable 230.

[0040] In one specific embodiment, the device to be transported 40 is a vacuum suction cup, and the shape of the mounting bracket 210 matches the shape of the vacuum suction cup.

[0041] Preferably, refer to Figures 1 to 4 On the orthographic projection surface of the connecting structure 20, the fixing frame 210 is circular or regular polygonal, and the fixing plates 220 are evenly arranged on the fixing frame 210 along the circumference of the fixing frame 210.

[0042] The vacuum suction cup is disc-shaped. To ensure spatial consistency between the center of gravity of the vacuum suction cup and the center of gravity of the mounting frame 210, the mounting frame 210 is designed as a regular circular or polygonal shape to conform to the shape of the vacuum suction cup, thus maintaining stability when the vacuum suction cup is connected to the bottom of the mounting frame 210. The fixing plates 220 are evenly distributed on the top of the mounting frame 210, ensuring that all the connecting cables 230 are evenly distributed to apply uniform tension to the vacuum suction cup, forming a "single-end to multiple-end" conical structure to ensure the stability of the vacuum suction cup's center of gravity.

[0043] In a specific embodiment, such as Figures 1 to 4 As shown, the fixing frame 210 is circular. As an example, there are six fixing plates 220, which are evenly arranged on the top of the fixing frame 210.

[0044] In one specific embodiment, the fixing plate 220 includes a fixing part and a connecting part 2200. The fixing part is connected to the top of the fixing frame 210, and the connecting part 2200 is disposed perpendicular to the fixing part and extends toward the bottom of the fixing frame 210, so that the fixing plate 220 forms an inverted "L" shaped structure. The length of the connecting part 2200 extending downward is greater than the thickness of the fixing frame 210.

[0046] The blind holes 400 on the vacuum suction cup are evenly distributed along the circumference of the vacuum suction cup. The through hole 2210 can be set as a U-shaped hole, and the position of the fastener 240 inserted into the U-shaped hole can be adjusted to adjust the distance between the vacuum suction cup and the bottom end of the fixing frame 210.

[0047] In one specific embodiment, the blind hole 400 is provided with threads, and the fastener 240 may be a threaded component such as a screw or bolt.

[0048] Preferably, refer to Figure 1 , Figure 2 and Figure 5 The support structure 10 includes a base structure 100, a first frame 110 vertically disposed on the base structure 100, and a second frame 120 vertically connected to the first frame 110. The base structure 100 and the second frame 120 are respectively located at both ends of the first frame 110, and the displacement component 30 is connected to the second frame 120.

[0049] The base structure 100 is placed on the mounting surface of the hoisting mechanism to provide stable support for the hoisting mechanism. The first frame 110 and the second frame 120 are combined to form a frame, on which the displacement component 30 can be installed to perform hoisting of the vacuum suction cup or other equipment 40 to be transported.

[0050] Preferably, refer to Figure 1 and Figure 2 The support structure 10 also includes a slide rail 130 extending along the length of the second frame 120 on the second frame 120, and a slider 140 on the slide rail 130. The displacement component 30 is connected to the slider 140 and moves along the slide rail 130 through the slider 140.

[0051] The extension direction of the slide rail 130 is consistent with the length direction of the second frame 120.

[0052] Preferably, refer to Figure 1 and Figure 2 The displacement component 30 includes a drive member 300 and a tension member 310. The fixed end of the drive member 300 is connected to the slider 140, and the output end is connected to the main connector 200 through the tension member 310. The output end rotates to wind up or unwind the tension member 310.

[0053] The displacement component 30 enables the vacuum suction cup to move along the length direction of the second frame 120 via the slide rail 130 and the slider 140, and enables the vacuum suction cup to move along the length direction of the first frame 110 via the drive component 300 and the pulling component 310.

[0054] In one specific embodiment, reference Figure 1 and Figure 2 The drive component 300 can be a motor, and the pulling component 310 can be a belt. The displacement component 30 also includes a remote controller 320, which is used to remotely control the motor to move along the length direction of the second frame 120 via the slider 140, and also to remotely control the motor to wind or unwind the belt so that the vacuum suction cup moves up or down along the length direction of the first frame 110.

[0055] Preferably, refer to Figure 1 , Figure 2 and Figure 5 , Figure 6 The base structure 100 includes a base plate 1000 connected to the first frame 110, a plurality of tubes 1010 disposed on the side wall of the base plate 1000, a plurality of rods 1020 matching the tubes 1010, and a plurality of support members 1030. One end of the rod 1020 is telescopically connected to the tube 1010, and the other end is connected to the support member 1030.

[0056] Among them, such as Figure 1 As shown, rod 1020 is in the extended state, as... Figure 2 As shown, the rod 1020 is in a retracted state. For narrow installation spaces, the length of the rod 1020 protruding from the tube 1010 can be appropriately reduced, allowing the hoisting mechanism to be fully inserted into the installation space while occupying a smaller area. For larger installation spaces, the length of the rod 1020 protruding from the tube 1010 can be appropriately increased, increasing the support area of ​​the base structure 100 and thus improving the overall balance of the hoisting mechanism.

[0057] In one specific embodiment, the body of the rod 1020 is a telescopic structure.

[0058] In a specific embodiment, such as Figure 1 , Figure 2 and Figure 5 , Figure 6 As shown, the base plate 1000 is rectangular, and each of the four side walls of the base plate 1000 is provided with a tube 1010 and a rod 1020 that matches the tube 1010. Each rod 1020 is provided with a support member 1030 at the end away from the tube 1010.

[0059] In one specific embodiment, the support member 1030 is threadedly connected to the rod body 1020. The support member 1030 can be rotated to spiral up or down, changing its height position to adjust the distance between the base plate 1000 and the mounting surface of the hoisting mechanism.

When the first positioning hole and the second positioning hole are aligned, the locking member 1040 passes through the first positioning hole and is connected to the second positioning hole.

[0061] When the locking member 1040 passes through the first positioning hole and connects to the second positioning hole, the rod 1020 cannot move relative to the tube 1010, so that the exposed length of the rod 1020 is fixed and cannot be adjusted.

[0062] Preferably, refer to Figure 1 , Figure 2 and Figure 5 , Figure 6 The support structure 10 also includes a stabilizing member 150, which includes a sleeve portion 1500 and an inclined reinforcing portion 1510.

One end of the reinforcing portion 1510 is fixedly connected to the sleeve portion 1500 and the other end is connected to the second frame 120.

[0063] The first frame 110, the second frame 120, and the reinforcing part 1510 form a stable triangular structure to improve the overall strength of the support structure 10. The reinforcing part 1510 supports the second frame 120 when the displacement component 30 slides on it, thus counteracting the pressure generated on the second frame 120 under the action of the displacement component 30 and enhancing the assembly stability of the first frame 110 and the second frame 120. The connection between the sleeve part 1500 and the first frame 110 and the second frame 120 is achieved by a sleeve-like design, facilitating the installation and disassembly of the two frames.

[0067] In one specific embodiment, the roller component 1050 may be a heavy-duty omnidirectional wheel.

[0068] In a specific embodiment, such as Figure 1 and Figure 2 As shown, the base structure 100 also includes two handles 1060 symmetrically arranged on both sides of the top surface of the base plate 1000.
