FIG. 3 is a schematic cross-sectional view of the support shaft assembly of this embodiment;

the figures in the drawings represent:

the device comprises a connecting rod 1, a bearing ring 11, a lifting frame body 2, a cross beam 21, a vertical beam 22, a slide rail 23, a base 3, a support shaft 31, a clamping block 32, a bayonet 33, a fixing beam 4, a guide seat 41 and a guide ring 42.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be understood that the described embodiments are only some embodiments of the present invention, and not all embodiments.

Example (b):

referring to fig. 1 to 3, the present embodiment is a high-bearing-strength supporting shaft fixing structure, which includes a connecting rod 1 connected to a driving end (not shown), a bearing ring 11 disposed at a bottom end of the connecting rod 1, a supporting shaft assembly penetrating the bearing ring 11, and a lifting frame 2 for bearing the supporting shaft assembly.

The top end of the connecting rod 1 is connected with a hydraulic cylinder for driving the connecting rod to lift, and the lifting frame body 2 is provided with a slide rail for guiding.

The lifting frame body 2 comprises a cross beam 21 and vertical beams 22 symmetrically arranged on two sides of the cross beam 21; the rear side of the vertical beam 22 is mounted with a slide rail 23 arranged along its height.

The central point of crossbeam 21 puts and is equipped with the back shaft subassembly, and the back shaft subassembly includes the base 3 of U type, transversely runs through the back shaft 31 of base 3 both sides, can dismantle the fixture block 32 that is used for the spacing back shaft 31 of joint on locating the lateral wall of base 3.

The support shaft 31 is provided with an arc-shaped bayonet 33 at the periphery of the end part of the base 3, the clamping block 32 is correspondingly matched and clamped with the bayonet 33, and the clamping block 32 is locked and fixed to the base 3 by a bolt.

High bearing strength back shaft fixed knot constructs still including the fixed beam 4 that is used for leading connecting rod 1, and the side of fixed beam 4 is equipped with the guide holder 41 of U type, is equipped with in the guide holder 41 to be used for the cover to locate the guide ring 42 of connecting rod 1 periphery, and guide ring 42 does not hinder connecting rod 1 lift removal.

When the embodiment is applied, the supporting shaft assembly with the effectively fixed bearing ring 11 is arranged on the lifting frame body 2, so that the stable lifting of the lifting frame body 2 is ensured; support shaft 31 and fixture block 32 carry out spacing cooperation among the support shaft subassembly, and the unable deflection angle of support shaft 31 makes its performance that possesses high bearing, and the operation of lifting and hanging is more stable.

What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
