[0029] The conventional jacking device uses a cylinder as a driving mode, and the driving rod of the cylinder directly acts on the upper object plate. Since the cylinder acts, the entire jacking operation is provided with jacking force by the cylinder, and the stability is relatively poor.

[0030] Referring to the drawings, a jacking device is provided, comprising a base 1, a load plate 2, a jacking frame 3, a driving device 4 and a guide 5; the upper surface of the base 1 and the lower surface of the load plate 2 are provided with jacking blocks 6 at corresponding positions;

[0031] The driving device 4 is connected to the base 1, and the output end of the driving device 4 is connected to the jacking frame 3, so that the jacking frame 3 can reciprocate relative to the base 1; the jacking frame 3 is provided with a jacking part 31, which cooperates with the jacking blocks 6 to realize the up-down movement of the load plate 2; the jacking frame 3 abuts against the jacking blocks 6 from the first position to the second position, so that the jacking blocks 6 in contact with each other are separated, thereby realizing the jacking of the load plate 2; the jacking frame 3 moves from the second position to the first position, so that the jacking blocks 6 separated from each other are brought together, thereby realizing the lowering of the load plate 2; the jacking frame 3 and the load plate 2 are in a locked state after jacking is completed; one end of the guide 5 is fixedly connected to the base 1, and the other end is movably connected to the load plate 2; under the driving action of the jacking frame 3, the load plate 2 moves along the axial direction of the guide 5. Among them, the guide 5 can be a guide column, the load plate 2 has a corresponding hole, the guide column is inserted into the hole, and the depth of the hole is associated with the stroke of the jacking of the load plate 2, so as to avoid the loss of interference between the load plate 2 and the guide column.

[0032] As shown in a specific scheme, the driving device 4 provides a horizontal force to drive the jacking frame 3 to move left, and at the same time, under the action of the jacking blocks 6, the jacking frame 3 also moves upward, when from the first position to the second position, the jacking is completed, at this time, through the jacking frame 3, the rigid contact between the jacking frame 3 and the jacking blocks 6 is realized, and the jacking frame 3 and the jacking blocks 6 are in a locked state, so that the driving device 4 does not need to provide continuous jacking force, and through the rigid connection, the entire device is in a stable contact state, and no visible deformation or shaking occurs, which has better stability compared with the prior art. The first position and the second position refer to a certain point position in the process, and can also refer to the initial position and the terminal position in a specific state.

[0033] In a specific embodiment, the base 1 is provided with a limiting block 7, the limiting block 7 is arranged on both sides of the jacking frame 3, and the limiting block 7 is in clearance fit with the jacking frame 3. Through the arrangement of the limiting block 7, the jacking frame 3 moves within a specified stroke space.

[0034] In a specific embodiment, the jacking part 31 is provided with a horizontal support part 32 on the upper and lower surfaces respectively, the upper jacking block 6 and the lower jacking block 6 are respectively provided with a horizontal contact part 61 matched with the horizontal support part 32, and the horizontal contact realizes posture locking. When the jacking part 31 is completely inserted between the jacking blocks 6, the contact surface at this time is the horizontal support part 32 of the jacking part 31 and the horizontal contact part 61 of the limiting block 7, and as shown in the figure, the upper and lower surfaces are in a stacked state, and since it is horizontal contact, no sliding occurs, and the load plate 2 is rigidly supported.

[0035] In a specific embodiment, the lifting part 31 is provided with a V-shaped contact part 33, and the lifting block 6 is provided with a matching inclined contact part 62. With the movement of the lifting frame 3, the V-shaped structure facilitates the insertion of the lifting part 31 between the lifting blocks 6.

[0036] In a specific embodiment, the lifting block 6 is provided with a bearing 63 on the side, and the lifting part 31 is provided with an auxiliary driving block 34, which has a V-shaped contact end at the front end. The auxiliary driving block 34 cooperates with the corresponding upper and lower bearings 63 to separate the corresponding upper and lower bearings 63, thereby achieving the lifting of the object plate 2, or to bring the corresponding upper and lower bearings 63 closer, thereby achieving the lowering of the object plate 2. The auxiliary driving block 34 is connected with the lifting part 31. Due to the rolling friction characteristics of the bearing 63, when the auxiliary driving block 34 is inserted into the bearing 63, the bearing 63 drives the upper lifting block 6 to move upward, and at this time, a certain gap is also more convenient for the insertion of the lifting part 31 between the upper and lower lifting blocks 6.

[0037] Optionally, during the lifting process, the auxiliary driving block 34 cooperates with the bearing 63 earlier or synchronously with the cooperation of the lifting part 31 and the lifting block 6. Early contact can make the upper lifting block 6 move upward a little bit in advance; synchronous contact can make the auxiliary driving block 34 and the bearing 63, and the lifting part 31 and the lifting block 6 contact synchronously, and simultaneously realize the left movement. The shape of the auxiliary driving block 34 should be adapted and cannot interfere with the contact between the horizontal support part 32 of the top part and the limiting block 7. For example, the V-shaped contact end of the auxiliary driving block 34 can be appropriately larger than the V-shaped contact part 33 of the lifting part 31, thereby realizing early contact; or the shape and size of the auxiliary driving block 34 can be kept the same, thereby realizing synchronous contact. For another example, the thickness of the auxiliary driving block 34 cannot be greater than the thickness of the lifting part 31, and cannot exceed the surface of the upper and lower horizontal support parts 32, so as not to affect the function of the horizontal support part 32.

[0038] In a specific embodiment, the object plate 2 is provided with a positioning device 8, which can be a positioning pin, for adapting to the positioning hole of the carried object.

[0039] In a specific embodiment, the driving device 4 is connected with an auxiliary driving plate 9, and the bottom of the auxiliary driving plate 9 is slidingly connected with the base 1. The auxiliary driving plate 9 is provided with a connecting part, and the lifting frame 3 is provided with a connecting groove matched with the connecting part, and the two are movably connected, so that the lifting frame 3 can move up and down relative to the auxiliary driving plate 9. The auxiliary driving plate 9 and the base 1 can be slidingly connected, and the base 1 is provided with a sliding rail structure as shown. Since the lifting frame 3 is a composite movement to the left and upward, the lifting frame 3 and the auxiliary driving plate 9 are movably connected and do not interfere with each other.

[0040] The connection of various components or structures in the present application is not completely shown in the drawings, and can be connected by the connection method in the art. The present application does not limit the use of prior art.

[0041] The above merely is the preferred embodiment of the present application, it should be pointed out that the above preferred embodiment should not be regarded as the limitation of the present application, the protection scope of the present application should be limited by the range defined by the claims. For the ordinary skilled in the art, without departing from the spirit and scope of the present application, can make several improvements and refinements, these improvements and refinements should also be regarded as the protection scope of the present application.
