Embodiment 1

[0076] Such as Figure 6 ~ Figure 7 As shown, the suspension oil cylinder provided by the embodiment of the present invention includes a cylinder 59, a piston rod 512, a cylinder stroke detection device 7 and a damping support, and one of the cylinder 59 and the piston rod 512 can pass through the damping support. The seat forms an elastic connection with the external connecting body;

[0077] The cylinder stroke detection device 7 includes a detection module 71 and a moving body 72, and the detection module 71 can send out a cylinder displacement detection signal corresponding to the position of the moving body 72 in real time during the relative movement of the moving body 72 and the detection module 71;

[0078]One of the moving body 72 and the detection module 71 (which may be the detection module 71 ) is fixedly connected to the cylinder 59 , and the other of the moving body 72 and the detection module 71 is fixedly connected to the piston rod 512 .

[0079] In the prese...

Embodiment 2

[0106] Such as Figure 8 and Figure 9 As shown, this embodiment is basically the same as Embodiment 1, and the difference is that in this embodiment, the anti-loosening body (which can be the end cap 52) can be connected through a detachable connection structure (which can be the same as Figure 6 The anti-loosening bolts 51 shown have the same or similar structure) are connected with the piston rod 64, the piston rod 64 is fixedly connected with the inner protective shell 62, and the cylinder barrel 63 is fixedly connected with the outer protective shell 61. The inner protective shell 62 is sheathed outside the cylinder 63 , and the cylinder 63 is interposed between the inner protective shell 62 and the piston 65 at the end of the piston rod 64 . The outer protective shell 61 is sheathed outside the inner protective shell 62 , and the inner protective shell 62 can slide relative to the cylinder barrel 63 and the outer protective shell 61 .

Abstract

The invention discloses a suspension cylinder and a crane, relates to the technical field of engineering machinery, and solves the problem that in the prior art, the capability of a suspension cylinder for adapting to complex and severe conditions is poor. The suspension cylinder comprises a cylinder, a piston rod, a cylinder stroke detection apparatus and a vibration damping bearer, wherein one of the cylinder and the piston rod is connected with the vibration damping bearer, and the cylinder stroke detection apparatus comprises a movable body and a detection module. The detection module gives off corresponding cylinder displacement detection signals when the movable body and the detection module move relative to each other. Either the movable body or the detection module is fixedly connected with the cylinder, and the other one of the movable body and the detection module is fixedly connected with the piston rod. The crane employs the suspension cylinder provided in the invention. The capability of the suspension cylinder for adapting to complex and severe conditions is improved.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a suspension oil cylinder and a crane provided with the suspension oil cylinder. Background technique [0002] Suspension is a general term for all force-transmitting connection devices between the vehicle frame (or load-bearing body) and the axle (or wheel) and the connected components. The main function of the suspension is to transmit the force between the wheel and the frame All forces and moments, and ease the impact of the car when driving on uneven roads, attenuate the vibration of the bearing system (or understood as vibration) caused by it, so as to ensure the ride comfort of the car. Suspension is mainly composed of elastic elements, shock absorbers, guide mechanisms and stabilizer bars. Suspension can be divided into independent suspension and non-independent suspension. The axle is a device that is connected to the frame (or load-bearing body) through ...
