The conveying mechanism includes a plurality of conveying rollers and a conveying roller drive assembly arranged at intervals. The transfer mechanism includes a lifting assembly, a plurality of conveying forks arranged on the lifting assembly, and a conveying fork drive assembly. The plurality of conveying forks are respectively arranged at the intervals between the conveying rollers; at least one end of the conveying fork extends out of the frame, and a transition plate is provided on the frame at the protruding end of the conveying fork, and a conveying fork avoidance groove is provided on the transition plate.
[0004] This device can raise the conveyor fork to carry out transfer work when transfer is required; when transfer is not required, the conveyor fork is lowered to avoid affecting transportation. However, the cam-based lifting mechanism used in this device causes the conveyor fork to move horizontally during the raising and lowering process. This requires sufficient clearance for the conveyor mechanism within the frame, which may ultimately make the overall structure of the transfer machine too large. Utility Model Content
[0005] The technical problem to be solved by the present invention is to provide a lifting device, which can realize that the lifted device only moves in the vertical direction during the lifting process, thereby reducing the size of the avoidance space required to be set in the corresponding equipment.
[0006] The utility model is realized through the following technical solutions:
[0007] The lifting device comprises: a lifting part for driving the lifted component to be lifted, comprising a lifting base, a lifting cylinder and a plurality of guide rods, wherein the lifting base is provided with a accommodating cavity, and the lifting cylinder is arranged in the accommodating cavity; a plurality of guide rods are arranged at the bottom of the lifting base and parallel to the lifting direction of the lifting part; a force-applying part for applying a lifting force to lift the lifting part, comprising a base, a lifting protrusion, at least one driving rod and a plurality of groups of guide clamping parts, wherein the lifting protrusion is placed on the supporting surface of the base, and a lifting curved surface adapted to the lifting cylinder is provided thereon; the driving rod is used to drive the lifting protrusion to move in the horizontal direction to lift or lower the lifting cylinder; a plurality of groups of guide clamping parts are arranged on the base, and contain a limiting space therein for clamping and limiting the guide rod.

[0010] As a further improvement of the present invention, the guide clamping portion includes a pair of clamping wheels, and the limiting space is formed between the pair of clamping wheels.
[0011] As a further improvement of the present invention, the force applying portion includes two driving rods, which are respectively arranged on both sides of the lifting protrusion for jointly controlling and driving the lifting protrusion to move in the horizontal direction.
[0012] As a further improvement of the present invention, the lifting cylinder includes a center rod, a ball bearing sleeved outside the center rod, and a movable ring sleeved outside the ball bearing.
[0013] As a further improvement of the present invention, the lifting protrusion includes a stress relief groove provided on the outer surface and extending to the bottom.

[0016] As a further improvement of the present invention, the conveying and transferring kit includes a conveying fork, and an extension portion is provided on the top of the conveying fork. When the conveying fork is in a raised state, the extension portion is placed outside the frame body; an avoidance slope structure is provided on the bottom of the extension portion and on both sides of the conveying fork, which is used to avoid the transmission kit during the descent of the conveying fork.
[0017] The beneficial effect of the present invention is that, under the structure of the jacking device, it is ensured that the lifted component will only move in the vertical direction during the lifting operation.

[0026] The present invention will be described in further detail below based on the accompanying drawings and implementation examples.
[0027] In this specification, directional terms such as up, down, left, right, front, back, front, back, top, and bottom, which are mentioned or may be mentioned, are defined relative to the configurations shown in the accompanying drawings. The terms "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may vary depending on the location and usage of the component. Therefore, these or other directional terms should not be construed as restrictive.
[0028] Example 1:
[0029] This embodiment provides a lifting device, such as Figure 1 As shown, it mainly comprises a lifting part 1 and a force applying part 2. The force applying part 2 is used to provide a lifting force to control the lifting and lowering movement of the lifting part 1, and the lifting part 1 can drive the lifted component arranged thereon to be lifted or lowered.
[0030] like Figure 1 and 3 As shown, the lifting unit 1 comprises a lifting base 101, a lifting cylinder 102, and guide rods 103. In this embodiment, a receiving cavity 101-1 is defined at the center of the lifting base 101, and the lifting cylinder 102 is disposed within this receiving cavity 101-1. In this embodiment, four guide rods 103 are disposed at the bottom of the lifting base 101, located at the four corners of the lifting base 101. All four guide rods 103 point vertically downward, aligning with the vertical displacement direction of the lifting unit 1.
[0031] like Figure 1 and 4As shown, the force-applying unit 2 comprises a base 201, lifting protrusions 202, a drive rod 203, and a guide clamping portion 204. In this embodiment, the lifting protrusions 202 are placed on the supporting surface 201-1 of the base 201 and are moved horizontally by the drive rod 203. There are four sets of guide clamping portions 204, matching the number and position of the guide rods 103. When the guide rods 103 are placed within the confined spaces of the guide clamping portions 204, the lifting unit 1 can only move vertically.
[0032] The structure of the force applying part 2 cooperates with the structure of the lifting part 1 to realize the control of the lifting of the lifting part 1. Figure 1 Take the jacking device placement perspective shown in as an example. When the jacking device is installed, the jacking protrusion 202 contacts the jacking cylinder 102 through the jacking curved surface and provides support at the same time. Therefore, the contact points of the jacking protrusion 202 and the jacking cylinder 102 are distributed on the jacking curved surface, and the height of the contact points can change with the horizontal movement of the jacking protrusion 202. Figures 1 to 2 For example, when the driving rod 203 drives the lifting protrusion 202 to move leftward, the height of the contact point is lowered, and thus the height of the lifting unit 1 as a whole is also lowered. When the lifting protrusion 202 moves in the opposite direction, the height of the lifting unit 1 as a whole is raised. At the same time, the interaction between the guide rod 103 and the guide clamping portion 204 also prevents the lifting unit 1 from deviating horizontally during lifting.
[0033] This structure ensures that when the lifting device is performing lifting work, the lifted component will only move in the vertical direction, which means that the avoidance space required for the displacement of the lifted component in the components used in conjunction with the lifted component can be smaller.
[0034] Preferably, if Figure 1 As shown, the lifting device further includes an auxiliary part 3 for auxiliary supporting the lifting part 1, which can share the pressure for the lifting protrusion 202 and ensure that the lifting part 1 can be lifted and lowered smoothly without tilting.
[0035] The auxiliary part 3 includes a movable base 301, a movable support rod 302 and a fixed support rod 303. Figure 1 and 4As shown, the movable base 301 is placed on the base 201 and connected to the lifting protrusion 202; in this embodiment, there are four fixed support rods 303, two of which are placed on the same side of the lifting base 101, and the four fixed support rods 303 are fixedly connected to the bottom of the lifting base 101; accordingly, in this embodiment, there are four movable support rods 302, one end of the movable support rod 302 is movably connected to the movable base 301, and the other end is movably connected to the fixed support rod 303. Under this structure, Figures 1 to 2 For example, when the driving rod 203 drives the lifting protrusion 202 to the left, it also drives the movable base 301 to move. At this time, the distance between the lifting part 1 and the force-applying part 2 decreases, and the movable base 301 drives the movable support rod 302 to rotate. On the one hand, it ensures that the lifting part 1 will not be interfered with in its descent, and on the other hand, it allows the auxiliary part 3 to still provide a certain degree of auxiliary support for the lifting part 1 through the movable support rod 302 and the fixed support rod 303.
[0036] Preferably, if Figures 1 and 2 As shown, the fixed support rod 303 is vertically fixedly installed at the bottom of the jacking base 101. Under this structure, when the movable support rod 302 is completely flat and the jacking part 1 is lowered to the lowest height, the fixed support column 303 can still provide auxiliary support, so that the jacking part 1 will not directly press down on the force-applying part 2, thereby avoiding damage to components of the force-applying part 2 during the descent process. At the same time, the presence of the fixed support rod 303 ensures that a final support distance is always maintained between the jacking part 1 and the force-applying part 2. Therefore, during some maintenance work on the jacking device, it can provide construction personnel with a stable operating space, for example, making it convenient for construction personnel to remove structures such as the drive rod 203 for repair, maintenance, or replacement.
[0037] Preferably, the guide clamping portion 204 includes a pair of clamping wheels, and a limiting space is formed between the pair of clamping wheels. Under this structure, while ensuring the limiting guiding effect, the friction between the guide clamping portion 204 and the guide rod 103 is reduced, making the lifting of the lifting portion 1 smoother.
[0038] Preferably, if Figure 1 and 4As shown, the force-applying portion 2 includes two drive rods 203, which are respectively arranged on either side of the lifting protrusion 202 to jointly control and drive the left and right movement of the lifting protrusion 202. On the one hand, the two drive rods 203 can provide a more stable driving force for the lifting protrusion 202, thereby providing a more stable drive for the lifting and lowering of the lifting portion 1, and also increase the upper limit of the weight of materials that the lifting portion 1 can lift. On the other hand, under this structure, if one drive rod 203 is damaged and cannot provide thrust, the remaining drive rod 203 can still ensure that the force-applying portion 2 can provide the lifting work of light materials.
[0039] At the same time, compared with the structure of the ordinary jacking device, which uses four hydraulic rods and other driving components to directly perform the jacking work, under the structure of this embodiment, even if one driving rod 203 is damaged, the jacking part 1 can still be guaranteed to carry out the lifting work smoothly as a whole in a short time, thereby making the jacking device have stronger emergency response capabilities.
[0040] Preferably, if Figures 1 and 2 As shown, the lifting cylinder 102 includes a center rod, a ball bearing mounted on the center rod, and a movable ring mounted on the ball bearing. With this structure, when the lifting protrusion 202 moves relative to the lifting cylinder 102, the friction between the two is reduced, so the lifting part 1 can be raised and lowered more smoothly.
[0041] Preferably, if Figures 1 and 2 As shown, the lifting protrusion 202 includes a stress relief groove 202-1 disposed on its outer surface and extending to the bottom. When the lifting cylinder 102 is lifted to its highest point by the lifting protrusion 202, it is embedded in the stress relief groove 202-1. On the one hand, the stress relief groove 202-1 can limit the position of the lifting cylinder 102, preventing it from sliding off the top of the lifting protrusion 202. On the other hand, the pressure exerted on the lifting protrusion 202 by the lifting portion 1 and the object supported thereon can be dispersed, preventing a large pressure from being applied to a specific point on the lifting protrusion 202, thereby preventing damage to the lifting protrusion 202 during use.
[0042] Example 2:
[0043] This embodiment provides a transfer machine, such as Figure 5 As shown, the transfer machine mainly includes two components: the conveying part A and the transfer part B.
[0044] The conveying section A comprises a frame body A01, a plurality of conveying rollers A02 mounted on the frame body A01, and a transmission assembly A03 providing driving force for the conveying rollers A02. Therefore, a first conveying direction is formed on the conveying section A, which is also the main conveying direction of materials.
[0045] The transfer section B includes multiple transport and transfer kits B01, which are mounted on the lifting base 101 of the lifting device in Example 1. When the lifting device is in the raised position, the multiple transport and transfer kits B01 are lifted from the gaps between the conveyor rollers A02. The conveying surface on these kits is higher than the conveying surface of the conveyor rollers A02, so the materials to be transferred can also be lifted. At the same time, the transport and transfer kits B01 are formed with a second conveying direction. In this embodiment, the second conveying direction is perpendicular to the first conveying direction. Therefore, after the materials to be transferred are lifted, they will be directly transferred to the adjacent conveyor track, and the transfer machine will complete the material transfer task.
[0046] Preferably, if Figure 5 As shown, the transmission assembly A03 includes a first drive wheel A03-1 fixed to one side of each conveyor roller A02, and multiple second drive wheels A03-2 mounted on the frame body A01. Each first drive wheel A03-1 has a second drive wheel A03-2 located at the bottom. A first drive chain link A03-3 connects the second drive wheel A03-2 to the top first drive wheel A03-1, and a second drive chain link A03-4 connects between adjacent sets of second drive wheels A03-2.
[0047] Under this structure, a certain lifting space is provided for the conveying and transferring kit B01 placed between the conveying rollers A02, avoiding the situation where a chain ring is directly connected between two adjacent conveying rollers A02 to block the conveying and transferring kit B01. At the same time, it ensures that only one driving device is provided in the conveying part A to provide power to any first driving wheel A03-1 or second driving wheel A03-2 to drive all the conveying rollers A02 to rotate, without the need to set up multiple driving devices.
[0048] Preferably, if Figure 6 As shown, the conveying and transfer kit B01 includes a conveying fork B01-1, which performs transport operations via a conveying bar mounted thereon. In this embodiment, the conveying bar of the conveying fork B01-1 is driven by a drive roller B01-2 located at the bottom of the conveying fork B01-1. Multiple sets of conveying forks B01-1 in the conveying and transfer kit B01 are driven by a single drive roller B01-2, ensuring synchronized operation of each set.
[0049] At the same time, if Figures 5 and 6The figure shows the specific structure of the conveying fork B01-1, wherein an extension portion B01-1a is provided on the top of the conveying fork B01-1. When the conveying fork B01-1 is in the jacking state, the extension portion B01-1a is placed outside the frame body A01 to facilitate the smooth transfer of materials to the adjacent conveying track; and an avoidance slope structure B01-1b is provided at the bottom of the extension portion B01-1a and on both sides of the conveying fork B01-1, so that when the conveying fork B01-1 descends, it will not interfere with the transmission kit A03 of the conveying roller A02, thereby ensuring the smooth lifting and lowering of the transfer part B.
[0050] Finally, it should be noted that the above implementation cases are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above implementation cases, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the above implementation cases, or replace some of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the implementation cases of the present invention.
