Problems solved by technology

In this way, once the oil circuit or valve parts leak, it is very easy to cause platform instability and safety accidents; at the same time, because the hydraulic oil in the oil cylinder still has a certain degree of compressibility, its support rigidity is poor. For large platforms, Due to the micro-movement of the support cylinder after being stressed, it may cause a large displacement of the local structure and poor stability

Abstract

A follow-up rigid support mechanism for a fixed position, comprising a follow-up rigid support rod and a locker, the upper end of the follow-up rigid support rod is connected with the bottom of the support platform, the lower end extends out after passing through the locker, and the bottom of the locker housing is connected with the drive The oil cylinder support base is connected, and the casing is provided with a drive shaft assembly and locking shaft assemblies on both sides. The drive shaft assembly includes a drive shaft and a drive gear sleeved on it. One end of the drive shaft is rotated and matched with the casing through a No. 1 bearing. The other end extends to the outside of the locker. The lock shaft assembly includes a lock shaft, a lock gear sleeved on one end of the lock shaft and meshed with the drive gear. It is a cylinder with a cutting plane, the arc-shaped surface of the middle section can be matched with the arc-shaped groove on the outer wall of the follow-up rigid support rod, and the depth of the arc-shaped groove is less than or equal to the cutting thickness of the cutting plane. The mechanism realizes the reliable fixed support after the platform is in place.

Description

technical field [0001] The invention belongs to the field of mechanical locking, and in particular relates to a fixed position follow-up rigid support mechanism, which is used to solve the problem of reliable fixed support after a tilting or lifting platform with high safety requirements is in place. Background technique [0002] The traditional tilting or lifting platform can tilt around the hinge point or lift up and down along the fixed axis through the oil cylinder. In this way, once the oil circuit or valve parts leak, it is very easy to cause the platform to become unstable and cause a safety accident; at the same time, because the hydraulic oil in the oil cylinder still has a certain compressibility, its supporting rigidity is poor. Due to the fretting of the support cylinder after being stressed, it may cause a large displacement of the local structure and poor stability. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a fixed ...
