Description
Technical Field
The utility model relates to the technical field of machinery, specifically speaking relates to an elastic support gyro wheel mechanism.
Background
In the oil cylinder direct-drive horizontal directional drilling machine, two ends of a piston rod of an oil cylinder are respectively fixed at the front end and the rear end of a crossbeam, and a cylinder barrel of a hydraulic cylinder is driven by high-pressure hydraulic oil to do reciprocating push-pull motion back and forth. In order to overcome the dead weight of the hydraulic cylinder, a rigid roller structure with a support frame is adopted to bear the weight of the cylinder barrel of the hydraulic cylinder, and the concentricity of the cylinder barrel and the piston rod of the hydraulic cylinder is kept.
Traditional gyro wheel bearing structure is rigid support structure, the piston rod that has greatly alleviated the cylinder dead weight and lead to seriously warp and the phenomenon of cylinder and piston rod decentraction, but this kind of rigid structure transition relies on gyro wheel and supporting mechanism's structural dimension, in case there is the processing deviation structural dimension, the concentricity of cylinder and piston rod just can't be adjusted, thereby lead to hydro-cylinder dead weight to act on the hydro-cylinder sealing washer with its contact, in the working process around the hydro-cylinder is ceaseless, the local damage of sealing washer accelerates, thereby cause the hydro-cylinder to leak, influence the normal operating of whole platform machine.

An object of the utility model is to provide an elastic support gyro wheel mechanism increases belleville spring adjusting device on original structure basis, utilizes adjusting screw to adjust belleville spring clamp plate and belleville spring for support cylinder barrel realizes that cylinder barrel reciprocates properly, makes cylinder and piston rod keep concentric, overcomes the influence of traditional rigidity gyro wheel structural size processing deviation.
The utility model discloses a following technical scheme realizes:
an elastic support roller mechanism is composed of a roller frame, rollers, a disc spring sleeve, an adjusting sleeve and a cylinder connecting support.
The idler wheel is installed below the idler wheel frame through an idler wheel pin shaft, the disc spring sleeve is fixedly installed above the idler wheel frame, and a disc spring group and a disc spring pressing sheet matched with the disc spring group are arranged in the disc spring sleeve in series and overlapped.
The adjusting sleeve is nested at the upper end of the disc spring sleeve, a locking nut and an adjusting screw matched with the locking nut are arranged at the center of a top plate of the adjusting sleeve, and a screw head of the adjusting screw is supported by the disc spring pressing plate.
The cylinder connecting support is nested on the disc spring sleeve and is fixedly connected with the lower end of the adjusting sleeve.
Preferably, the cylinder barrel connecting support is provided with a connecting mechanism for connecting the cylinder barrel of the oil cylinder.
Preferably, the disc spring group is formed by overlapping 8 disc springs in series.
The principle of the utility model is as follows:
