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 fixed-position follow-up rigid supporting mechanism comprises a follow-up rigid supporting rod and a locking device, the upper end of the follow-up rigid supporting rod is connected with the bottom of a supporting platform, the lower end of the follow-up rigid supporting rod penetrates through the locking device and then extends outwards, the bottom of a shell of the locking device is connected with a driving oil cylinder supporting base, and a driving shaft assembly and locking shaft assemblies on the two sides of the driving shaft assembly are arranged in the shell. The driving shaft assembly comprises a driving shaft and a driving gear arranged on the driving shaft in a sleeving mode, one end of the driving shaft is in running fit with the shell through a first bearing, the other end of the driving shaft extends to the outer portion of the locking device, and the locking shaft assembly comprises a locking shaft and a locking gear arranged at one end of the locking shaft in a sleeving mode and meshed with the driving gear. The end of the locking shaft is rotationally matched with the shell through a second bearing assembly, the middle section of the locking shaft is a cylinder with a cutting plane, the arc-shaped face of the middle section can be matched with an arc-shaped groove in the outer wall of the follow-up rigid supporting rod, and the depth of the arc-shaped groove is smaller than or equal to the cutting thickness of the cutting plane. The mechanism realizes reliable fixing and supporting 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] For the traditional tilting or lifting platform, the tilting around the hinge point or the lifting along the fixed axis is realized through the oil cylinder, etc. After it is in place, the oil circuit is locked by the hydraulic lock in the hydraulic system, so that the oil cylinder supports the platform. 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 stre...
