Description

Technical Field

[0001] This utility model belongs to the technical field of stacking equipment, specifically relating to a lifting mechanism with a cable limiting structure and a stacking equipment containing it. Background Technology

[0002] Cables are required during the use of stacking equipment. These cables move up and down with the lifting mechanism, and are typically suspended to facilitate this movement. However, because the cables are prone to swaying during this process, the lifting mechanism can pull on them, potentially causing damage or even breakage. Therefore, a lifting mechanism with a cable limiting structure and a stacking device incorporating it were designed to address these issues.

[0003] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this utility model and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this utility model. Utility Model Content

[0004] To overcome the shortcomings of the prior art, the purpose of this utility model is to provide a lifting mechanism with a cable limiting structure and a stacking device including it.

[0005] To achieve the above and other related objectives, this utility model provides a lifting mechanism with a cable limiting structure, comprising:

[0006] Mounting rack;

[0007] A lifting frame, which is vertically movable on the mounting frame;

[0008] The cable is located on one side of the lifting frame and is vertically mounted on the mounting frame;

[0009] An anti-deviation bracket is fixed to the lifting frame and located on the side of the lifting frame closest to the cable; one end of the cable passes vertically through the anti-deviation bracket. In this solution, the lifting mechanism uses the anti-deviation bracket to limit the cable's movement, preventing the cable from swaying due to movement while suspended, and solving the problem of cable damage caused by the lifting mechanism pulling on the cable during its up-and-down movement.

[0010] Furthermore, the anti-deviation frame includes a mounting plate fixed to the lifting frame. The mounting plate is connected to a connecting frame via a connecting rod. Two pressure rollers are provided on the side of the connecting frame near the cable. The two pressure rollers are located on opposite sides of the cable in the width direction and press against the mounting frame. In this design, the pressure rollers can roll vertically back and forth on the mounting frame when the lifting frame moves up and down. This movement limits the width of the cable and improves stability.

[0011] Furthermore, a roller is provided on the side of the connecting frame near the cable, and the roller is horizontally positioned between the two pressure rollers. In this design, the roller transforms sliding friction into rolling friction, reducing friction and preventing damage to the cable sheath.

[0012] Furthermore, a connecting sleeve is provided on the mounting plate, and the connecting rod passes through the connecting sleeve. A limit block is provided at one end of the connecting rod passing through the connecting sleeve, and a spring is sleeved at the end of the connecting rod near the cable. In this design, the spring is located between the connecting frame and the connecting sleeve, and the connecting rod can move within the connecting sleeve. The spring provides a certain buffering effect when the pressure roller rolls on the mounting frame.

[0013] Furthermore, the mounting frame includes a first horizontal beam, a second horizontal beam, a first vertical beam, and a second vertical beam. The first and second horizontal beams are horizontally aligned and vertically corresponding. The first and second vertical beams are of equal length and vertically fixed between the first and second horizontal beams. The lifting frame is positioned between the first and second vertical beams. In this design, the lengths of the first and second vertical beams are set to the height required for stacking. Both the first and second horizontal beams have structures that allow them to be connected and installed with stacking equipment. However, the connection structure is not a primary improvement protected by this patent and will not be elaborated upon here.

[0014] Furthermore, the lifting frame includes a base; a first mounting seat is fixed to the side of the base near the first vertical beam, and the anti-deviation frame is fixed to the first mounting seat; a second mounting seat is fixed to the side of the base near the second vertical beam, and two rows of pulleys are arranged on the side of the second mounting seat near the second vertical beam, with the two rows of pulleys located on both sides of the second vertical beam and pressing against it. In this design, when the lifting frame moves up and down, the pulleys roll on the second vertical beam. Each row of pulleys has two or more pulleys to ensure stable operation.

[0015] Furthermore, baffles are fixed on both sides of the first mounting base. The two baffles are located on both sides of the first vertical beam and are parallel to the first vertical beam. A vertical guide rail is provided on the first vertical beam at the position corresponding to each baffle. The baffles are connected to the corresponding vertical guide rails via sliders. In this design, connecting the baffles to the vertical guide rails on the first vertical beam improves the straightness of the lifting frame's vertical movement and enhances its motion accuracy.

[0016] Furthermore, a cable clamp is provided on the first vertical beam. The cable clamp is configured to hold one end of the cable. The cable clamp includes a bent plate located inside the cable and a pressure plate located outside the cable. The pressure plate is fastened to the first vertical beam by fasteners passing through the bent plate. The upper end of the bent plate is bent downwards towards the inside of the cable. In this design, the bending direction of the bent plate corresponds to the bending direction of the cable's fixed end, which can provide support for the bending point of the cable.

[0017] Furthermore, a guardrail is provided at the upper end of the base. In this design, the guardrail can protect the materials on the lifting frame.

[0018] This utility model also provides a stacking device, including a lifting mechanism with a cable limiting structure as described in any of the above technical solutions.

[0019] Due to the application of the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:

[0020] The present invention relates to a lifting mechanism with a cable limiting structure and a stacking device containing it. By setting an anti-deviation frame to limit the cable, it avoids the cable from swaying due to movement when suspended, and solves the problem of cable damage caused by the lifting mechanism pulling the cable when moving up and down.

[0035] In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0036] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0037] Example 1:

[0038] This embodiment provides a lifting mechanism with a cable 1 limiting structure, including:

[0039] Mounting bracket 2, see attached Figure 1 and attached Figure 2 As shown, the mounting frame 2 includes a first horizontal beam 201, a second horizontal beam 202, a first vertical beam 203, and a second vertical beam 204. The first horizontal beam 201 and the second horizontal beam 202 are horizontally aligned and vertically corresponding. The first vertical beam 203 and the second vertical beam 204 are of equal length and vertically fixed between the first horizontal beam 201 and the second horizontal beam 202. The lifting frame 3 is positioned between the first vertical beam 203 and the second vertical beam 204. The lengths of the first vertical beam 203 and the second vertical beam 204 are adjusted to the required stacking height. Both the first horizontal beam 201 and the second horizontal beam 202 have structures that allow them to be connected to stacking equipment. However, these connection structures are not a primary improvement protected by this patent and will not be elaborated upon here.

[0040] Lifting frame 3, see appendix Figure 1 and attached Figure 3 As shown, the lifting frame 3 is mounted on the mounting frame 2 in a vertically movable manner; how the lifting frame 3 on the stacking equipment achieves vertical movement through the driving device is existing technology, and the driving structure is not the main improvement point that this patent needs to protect, so this patent will not elaborate on it.

[0041] The lifting frame 3 includes a base 301; a guardrail 307 is provided at the upper end of the base 301. The guardrail 307 protects the materials on the lifting frame 3. The base 301 can be fitted with the structures required for the stacking equipment as needed, which will not be detailed here. A first mounting seat 302 is fixed to the side of the base 301 near the first vertical beam 203, and an anti-deviation frame 4 is fixed to the first mounting seat 302. A second mounting seat 303 is fixed to the side of the base 301 near the second vertical beam 204. Two rows of pulleys 304 are provided on the side of the second mounting seat 303 near the second vertical beam 204, respectively located on both sides of the second vertical beam 204 and pressing against it. When the lifting frame 3 moves up and down, the pulleys 304 roll on the second vertical beam 204. Each row of pulleys 304 has two or more pulleys to ensure stable operation.

[0042] Two baffles 305 are fixed on both sides of the first mounting base 302. The two baffles 305 are located on both sides of the first vertical beam 203 and are parallel to the first vertical beam 203. The two baffles 305 move up and down together with the first mounting base 302. A vertical guide rail 306 is provided on the first vertical beam 203 at the position corresponding to the baffles 305. See Appendix. Figure 6 As shown, the baffle 305 is connected to the corresponding vertical guide rail 306 via a slider. Connecting the baffle 305 to the vertical guide rail 306 on the first vertical beam 203 improves the straightness of the lifting frame 3's vertical movement and enhances its motion accuracy. The baffle 305 also provides protection, safeguarding the structure inside (e.g., cable 1) and preventing oil splashes (in case of lubricating oil spillage). The width of both baffles 305 is greater than the distance from the first mounting base 302 to the first vertical beam 203, ensuring proper installation and effective protection.

[0043] Cable 1, see appendix Figure 1 and attached Figure 6 As shown, cable 1 is located on one side of the lifting frame 3 and is vertically mounted on the mounting frame 2; cable 1 is a flat cable and is made of PC / ABS plastic.

[0044] Anti-deviation frame 4, see appendix Figure 4 As shown, the anti-deviation frame 4 is fixed on the lifting frame 3 (the anti-deviation frame 4 moves up and down together with the lifting frame 3), and the anti-deviation frame 4 is located on the side of the lifting frame 3 closest to the cable 1; one end of the cable 1 passes through the anti-deviation frame 4 vertically. The end of the cable 1 passing through the anti-deviation frame 4 is the fixed end, which is set on the mounting bracket 2 and connected to the power supply; the other end of the cable 1 is the moving end, which is connected to the drive device on the lifting frame 3, and the height of the moving end of the cable 1 rises and falls with the movement of the lifting frame 3.

[0045] The anti-deviation frame 4 includes a mounting plate 401 fixed on the lifting frame 3. The mounting plate 401 is connected to a connecting frame 403 via a connecting rod 402. Two pressure rollers 404 are provided on the side of the connecting frame 403 near the cable 1. The two pressure rollers 404 are located on both sides of the cable 1 in the width direction and are pressed against the mounting frame 2. The connecting frame 403 has a horizontally arranged Π-shaped structure with its opening facing the cable 1. The two pressure rollers 404 are located on both sides of the cable 1 and are pressed against the mounting frame 2. The pressure rollers 404 can roll vertically back and forth on the mounting frame 2 when the lifting frame 3 moves up and down. While moving, they can limit the width direction of the cable 1 and improve the stability of the movement.

[0046] A roller 405 is provided on the side of the connecting frame 403 near the cable 1. The roller 405 is horizontally positioned between two pressure rollers 404. The roller 405 is positioned close to the cable 1, and may or may not be in contact with the cable 1. When the roller 405 is in contact with the cable 1, it presses the cable 1 and rolls up and down. When the roller 405 is not in contact with the cable 1, the cable 1 has some room to move, but this is limited to a certain range to ensure that the lifting frame 3 does not pull on the cable 1. The roller 405 transforms sliding friction into rolling friction, reducing friction and preventing damage to the cable 1's outer sheath.

[0047] A connecting sleeve 406 is provided on the mounting plate 401, and a connecting rod 402 passes through the connecting sleeve 406. A limit block is provided at one end of the connecting rod 402 that passes through the connecting sleeve 406 (to prevent the connecting rod 402 from falling off the connecting sleeve 406; in implementation, only a certain limit is needed at the end). A spring 407 is fitted on the end of the connecting rod 402 near the cable 1. The spring 407 is located between the connecting frame 403 and the connecting sleeve 406, allowing the connecting rod 402 to move within the connecting sleeve 406. The spring 407 provides a certain buffering effect when the pressure roller 404 rolls on the mounting frame 2. The number of connecting sleeves 406 and connecting rods 402 is not limited to one; two of each can be provided. Two of each can make the anti-deviation frame 4 structure more robust and stable.

[0048] See appendix Figure 1 and attached Figure 5As shown, a cable clamp 5 is provided on the first vertical beam 203. The cable clamp 5 clamps one end (fixed end) of the cable 1. The cable clamp 5 includes a bent plate 501 located inside the cable 1 and a pressure plate 502 located outside the cable 1. The pressure plate 502 is fastened to the first vertical beam 203 by fasteners passing through the bent plate 501. The upper end of the bent plate 501 is bent downwards towards the inside of the cable 1. The number of cable clamps 5 is not limited to one. The bending direction of the bent plate 501 corresponds to the bending direction of the fixed end of the cable 1, which can provide support for the bending point of the cable 1. Here, "one end" of the cable 1 does not refer to one end of the cable 1, but to the section fixed on the first vertical beam 203. After the cable 1 is fixed at this point, it will be bent downwards to connect to the power supply. The downwardly bent part of the cable 1 is usually located inside the first vertical beam 203, so from the outside, the fixed position looks like one end of the cable 1. The material of the pad includes, but is not limited to, rubber; the material of the pad includes, but is not limited to, Q235.

[0050] The present invention relates to a lifting mechanism with a cable limiting structure and a stacking device containing it. By setting an anti-deviation frame to limit the cable, it avoids the cable from swaying due to movement when suspended, and solves the problem of cable damage caused by the lifting mechanism pulling the cable when moving up and down.

[0051] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
