Embodiment 1

[0035] Such as Figure 1 to Figure 7A jacking mechanism with good stability provided by the present invention includes a base 3, a traversing part that can move laterally along the base 3 and a lifting part arranged on the traversing part, and the traversing part includes a traversing seat 5 And the traversing handle 9, the base 3 is provided with a rotating seat 8, and the rotating seat 8 is provided with a ring convex cavity 83, and the traversing handle 9 includes a braking part 93 sequentially from one end to the other end, an annular protruding 92 and the threaded section 91, the annular protrusion 92 is located in the ring convex cavity 83, the lower end of the traversing seat 5 is in contact with the upper end of the base 3, and the traversing seat 5 is threadedly connected with the traversing handle 9;

[0036] The lifting part includes a cylindrical internal thread seat 4, a lifting handle 1 and a jacking rod 6, the internal thread seat 4 is provided with an internal ...

Embodiment 2

[0040] This embodiment is further limited on the basis of embodiment 1: as Figure 1 to Figure 7 , in order to facilitate the installation of the traversing handle 9 and simplify the structure of the present invention, which is beneficial to processing, manufacturing and assembly, the rotating seat 8 includes an upper cover 82 and a lower cover 81 connected by bolts, and the upper cover 82 and the lower cover 81 Grooves are provided on the connecting sides, and the two grooves constitute the ring convex cavity 83 .

Embodiment 3

[0042] The present embodiment is further limited on the basis of embodiment 1: as Figure 1 to Figure 7 , the lifting handle 1 includes a driving sleeve 11 and a brake lever 16 sleeved in the driving sleeve 11, one end of the driving sleeve 11 is hingedly connected with the jacking rod 6, and the driving sleeve 11 can go around the top When the lifting rod 6 rotates in the circumferential direction, one end of the brake rod 16 that penetrates into the drive sleeve 11 forms an oblique cutout 7 , and the other end of the brake rod 16 protrudes relative to the drive sleeve 11 .

[0043] The set driving sleeve 11 is convenient for fixing the relative position of the lifting handle 1 relative to the jacking rod 6: even if the brake rod 16 interacting with the axial teeth 41 is always located in the radial direction of the jacking rod 6, the set inclined The notch 17 makes the structural relationship between the lifting handle 1 and the axial tooth 41 a ratchet structure. By adjusti...

Abstract

The invention discloses a jacking mechanism with good stability. The jacking mechanism comprises a base, a horizontal moving part and a lifting part, wherein the horizontal moving part comprises a horizontal moving seat and a horizontal moving handle; a rotating seat is arranged on the base; an annular convex cavity is formed in the rotating seat; the horizontal moving handle comprises a braking part, an annular convex part and a threaded part; the lifting part comprises an internal threaded seat, a lifting handle and a jacking rod; an internal threaded hole is formed in the internal threaded seat; external threads and a plurality of axial teeth are formed on the jacking rod; a sealing ring is arranged between the upper end of the jacking rod and the internal threaded base; at least three horizontal adjusting parts which are not located on the same straight line and are in threaded connection with the base are arranged on the base; the horizontal adjusting parts comprise leveling bolts which are in threaded connection with the base and bottom plates which are arranged below the leveling bolts; the positions of the bottom plates on the axial direction of the leveling bolts are fixed; the leveling bolts can rotate around the axes of the leveling bolts. The selection of a support point is flexible, the applicable range is wide, the jacking is reliable, the service life is long, the bearing capacity is strong, and the jacking precision is high.

Description

technical field [0001] The invention relates to a device for supporting or leveling heavy objects, in particular to a jacking mechanism with good stability. Background technique [0002] Jacking equipment is mainly used in the hoisting, assembly, maintenance and installation of large-scale equipment and components to achieve leveling of equipment or components in the above process, and to create a gap between the bottom plate of the equipment and the ground to facilitate the positioning of the fork of the forklift or in the equipment. A rolling body is set between the ground and the ground. [0003] In the prior art, the above lifting equipment mostly adopts mechanical jacks, hydraulic jacks or hydraulic pump stations. However, in the prior art, it is more troublesome for the mechanical jacks and hydraulic jacks to realize their respective axial directions in the vertical direction, and the exposed threads of the mechanical jacks After dust is attached to it, it is easy to ...
