The two symmetrical groups of locking driving components 23 and the mechanical locking rod 24 form position locking for the telescopic cylinder actuating element, and provide balanced supporting force for the cylinder rod 22 of the telescopic cylinder, so that the locking effect is more stable.
On the basis of the embodiment, more than two groups of mechanical locking rods 24 and locking driving assemblies 23 can be formed so as to adapt to different load requirements, and the more than two groups of mechanical locking rods 24 and the locking driving assemblies 23 are uniformly distributed on the outer side part of the cylinder body 21 of the telescopic cylinder at equal intervals; the locking drive assembly 23 may take a variety of forms; the cylinder body is fixed by the cylinder rod instead of the cylinder body, and the required functions can be realized.
Optionally, the cylinder 21 is connected with a pressure sensing control box 25, and the pressure sensing control box 25 collects the pressure value of the cylinder rod 22 through a pressure signal transmission line 26.
The pressure sensing control box 25 and the pressure signal transmission line 26 are arranged, so that the pressure value of the cylinder rod 22 can be conveniently observed when the locking telescopic device acts, and after the pressure value of the cylinder rod 22 is stable, mechanical locking is performed; when the mechanical locking is released, whether the pressure value provided by the system to the cylinder rod 22 meets the required pressure value can be detected according to the pressure sensing control box 25, so that the condition that the mechanical locking is released due to small or large pressure supply is avoided, and the gesture of an executive component is changed due to insufficient pressure supply or exceeding a limit value of the system.
The embodiments of the present invention are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in this way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
