Fracturing truck large pump bi-directional self-adaptation shock absorber

Abstract

The invention provides a fracturing truck large pump bi-directional self-adaptation shock absorber. According to the shock absorber, the bottom of a box body is provided with a longitudinal shock absorbing base, the upper portion of the box body is provided with a bearing plate, a cross-shaped rubber partition plate is installed inside the box body, a longitudinal shock absorbing device is arranged inside the partition plate space, a transverse shock absorbing base, a connecting plate and a fixing rib plate are connected through bolts, transverse shock absorbing rubber is arranged between the transverse shock absorbing base and the fixing rib plate in an embedded mode, the tops of the transverse shock absorbing base and the transverse shock absorbing rubber are provided with sliding blocks, two sides of each sliding block are provided with transverse shock absorbing devices, and concave rubber is arranged between the two transverse shock absorbing devices. A longitudinal shock absorbing disc spring is sleeved on a longitudinal disc spring support, and two ends of the longitudinal disc spring support are respectively provided with a longitudinal disc spring sleeve and longitudinal shock absorbing rubber. A transverse disc spring sleeve and a transverse shock absorbing disc spring are sleeved on a transverse fixing double-thread screw, the end portion of the transverse fixing double-thread screw is fixed on the fixing rib plate through fixing nuts, and the sliding blocks are arranged between the two transverse shock absorbing disc springs.

Description

technical field [0001] The invention relates to the field of oil and gas field fracturing equipment, in particular to a two-way self-adaptive shock absorber for shock absorption of a large pump of a fracturing vehicle. Background technique [0002] Now the depth of well digging in oil fields is increasing, and the requirements for the pressure and displacement of fracturing vehicles are also getting higher and higher. In the National 863, the development of 3000 fracturing vehicles was proposed. The large pump of the 3000-type fracturing truck weighs more than 8 tons, and the driving roads are mostly in harsh road conditions such as deserts and hills or road conditions without roads. The horizontal vibration of the three-cylinder pump is severe when performing high-pressure fracturing. When the fracturing vehicle is driving and the large pump fracturing operation, the vertical vibration and horizontal vibration of the vehicle frame are violent, which may easily cause fatigue...

AI Technical Summary

Problems solved by technology

At present, there is no shock absorber on the market that meets the vibration damping requirements of the large pump of the fracturing truck in both directions. It only uses a layer of rubber to attenuate the vibration in the vertical direction, which is not targeted at the low-frequency vibration of the fracturing truck. not effectively
