Detailed Description

The present invention is further described with reference to the following drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.

Referring to fig. 1, a schematic view of an embodiment of a linked jacking device according to the present invention is shown. The utility model discloses a jacking device includes jacking portion 10, interlock portion and drive division 30, jacking portion 10 is in be provided with a plurality of groups on the length direction of interlock portion, drive division 30 drive wherein at least one jacking portion 10 jacking, jacking simultaneously under the drive of interlock portion of all the other jacking portions 10, simple structure has realized the synchronism of jacking, makes the execution of lift action more steady.

Referring to fig. 2, it is a front view of the jacking device of the present invention. Jacking portion 10 includes jacking axle 11, bearing fixing base 12 and jacking rod 13, and bearing fixing base 12 supports for jacking axle 11, and jacking axle 11 drives jacking rod 13 and rotates, and jacking rod 13's top motion curve is circular, and jacking rod 13 top can be followed low to high removal promptly, realizes the jacking action. Specifically, the jacking shaft 11 is rotatably connected with the bearing fixing seat 12, and the jacking rod 13 is fixedly connected with the jacking shaft 11. When the jacking shaft 11 rotates, the jacking rod 13 is driven to rotate, and the top of the jacking rod 13 moves from low to high, so that jacking is realized. The linkage part comprises a linkage part of a linkage rod 20; 21 and a linkage frame, wherein two ends of the jacking shaft 11 are respectively and fixedly connected with the linkage part of the linkage rod 20; 21, the linkage part of the linkage rod 20; the other end of the connecting rod 21 is rotatably connected with the connecting frame. When the jacking shaft 11 rotates, the linkage rod 20 links the part; 21 is driven to rotate, and the linkage rod 20 is linked with the part; the other end 21 produces displacement, the linkage frame is driven to move integrally, and the linkage parts of the other linkage rods 20 connected with the linkage frame; 21 is driven by the linking frame to rotate a certain angle, and further linked with the linking rod 20; the jacking shaft 11 connected with the jacking shaft 21 and the jacking rod 13 connected with the jacking shaft 11 rotate by corresponding angles, namely other jacking rods 13 rise by the same height, so that linkage jacking is realized. In order to ensure the strength of the linkage frame, the linkage frame adopts a hexagonal linkage shaft 22, and the linkage part is linked by the linkage rod 20; 21 is not convenient to be rotationally connected with the hexagonal linkage shaft, so the linkage frame also comprises a linkage plate 23, and because the hexagonal linkage shaft 22 is convenient to be locked, two ends of the adjacent linkage plate 23 are directly connected with the hexagonal linkage shaft 22, and the linkage part of the linkage rod 20 is connected; 21 is rotatably connected with the linkage plate 23. In order to drive the lifting shafts 11 to rotate, the driving part 30 includes a driver which drives at least one of the lifting shafts 11 to rotate. In this embodiment, the driver is a driving motor 31, the driver is the driving motor 31, and the driving motor 31 is connected to one of the jacking shafts 11. The driving motor 31 directly drives the jacking shaft 11 connected with the driving motor to rotate, other jacking shafts 11 rotate by the same angle under the transmission connection of the transmission part, and the jacking rods 13 on the jacking shafts 11 realize synchronous jacking.

Referring to fig. 3, in order to ensure the stability of supporting the workpiece, in this embodiment, the top of the lifting rod 13 is connected to a horizontal rod 14 axially disposed along the lifting shaft 11. During operation, because the work piece has a plurality of lifters 13 interlock liftings to support the work piece on length direction, consequently can guarantee that the work piece can not produce in length direction and rock, the setting up of horizontal pole 14 makes the work piece have sufficient support in width direction, guarantees that the work piece can not produce in width direction and rocks. Further, because the end of the jacking rod 13 rises along an arc line in the jacking process of the jacking rod 13, the real-time contact position of the end of the jacking rod 13 and the workpiece is constantly changed, namely friction exists between the end of the jacking rod 13 and the workpiece, and in order to reduce the friction, the top of the jacking rod 13 is rotatably connected with a jacking wheel 15. At the moment, the friction between the jacking rod 13 and the workpiece is rolling friction, so that the friction force is greatly reduced, the workpiece is protected, and the surface of the workpiece cannot be scratched. Meanwhile, in order to ensure the stability of the support of the jacking shaft 11, two bearing fixing seats 12 are arranged in the jacking portion 10, and the two bearing fixing seats 12 are respectively connected to two ends of the jacking shaft 11. The bearing fixing seat 12 and the driver are both fixed on the bottom plate 40. To make full use of space, the bearing housing is fixed to the upper surface of the base plate 40 and the driver is fixed to the lower surface of the base plate 40 in this embodiment.

Fig. 4 and 5 are schematic diagrams of a second embodiment of the present invention. Because when the driving motor 31 is used for driving the jacking shaft 11 to rotate, the torsion force borne by the driving motor 31 is too large, which results in short service life of the driving motor 31, in this embodiment, the middle part of the jacking rod 13 is fixedly connected with the jacking shaft 11, the driver is a driving cylinder 32, and the driving cylinder 32 is connected with the lower part of the jacking rod 13. When driving actuating cylinder 32 and promoting the removal of jacking pole 13 one end, the jacking pole 13 other end uses jacking axle 11 to rotate as the centre of a circle, realizes jacking of jacking pole 13, and the thrust that drives actuating cylinder 32 simultaneously is big, can guarantee to drive actuating cylinder 32's life when guaranteeing to jack-up jacking pole 13. Further, as the driving cylinder 32 is fixed in position, in order to prevent the situation that the pushing rod of the driving cylinder 32 is interfered and locked with the lifting rod 13 to prevent the lifting rod 13 from being pushed out, the lower part of the lifting rod 13 is provided with a guide groove 16, and the connecting shaft 33 passes through the guide groove 16 to be connected with the pushing rod of the driving cylinder 32. With the push of the pneumatic cylinder, the connecting shaft 33 moves in the guide groove 16, and the smooth push of the push rod to the jacking rod 13 is ensured. In order to prevent the driving cylinder 32 from pushing the lifting rod 13 by a large angle, the lifting rod 13 cannot be pushed to a proper angle due to the superposition interference between the push rod and the lifting rod 13, in this embodiment, the lifting rod 13 is set to be in a crank form, and the bent portion of the crank is fixedly connected with the lifting shaft 11.

When the utility model works, a workpiece is placed above the device, the jacking wheels 15 on the jacking rods 13 are contacted with the workpiece, the workpiece is stably supported by the jacking rods 13, the pneumatic cylinder pushes the lower ends of the jacking rods 13, the jacking rods 13 rotate by taking the jacking shafts 11 as circle centers, and the rotation of the jacking shafts 11 drives the linkage parts of the linkage rods 20; 21 rotating, the linkage frame is linked by the linkage rod 20; 21, the other linkage rods 20 are driven to move to pull the linkage parts; 21, so that the other jacking shafts 11 and the jacking rods 13 connected with the jacking shafts 11 rotate simultaneously, and the jacking rods 13 ascend or descend along the circular arcs to realize linked jacking. Simple structure has ensured the synchronism of jacking, makes the execution of lift action more steady simultaneously.
