Multi-functional slips flashboard

Abstract

The invention relates to the technical field of petroleum machines, and provides a multi-functional slips flashboard. The multi-functional slips flashboard comprises a flashboard body, a slips back and a tooth plate, wherein the flashboard body, the slips back and the tooth plate are sequentially installed together from back to front. The height of the slips back is smaller than that of the flashboard body; the front end of the flashboard body is provided with a first guide inclined plane of the flashboard body and a second guide inclined plane of the flashboard body, the first guide inclined plane is vertically arranged, the lower end of the first guide inclined plane inclines forwards, the second guide inclined plane is vertically arranged, and the upper end of the second guide inclined plane inclines forwards; the rear end of the slips back is provided with a first guide inclined plane of the slips back and a second guide inclined plane of the slips back, the first guide inclined plane and the second guide inclined plane are vertically arranged, the first guide inclined plane of the slips back is matched with the first guide inclined plane of the flashboard body, and the second guide inclined plane of the slips back is matched with the second guide inclined plane of the flashboard body. The multi-functional slips flashboard is small in height, good in clamping performance and self-locking performance and wide in application range, and can be universally used as the slips flashboard of a traveling slips, a fixed slips and a safety slips of a belt pressure operating device.

Description

technical field [0001] The invention relates to the technical field of petroleum machinery, in particular to a multifunctional slip ram. Background technique [0002] In the field of petroleum machinery technology, there are three types of slips currently used in workover rigs for hot work: universal slips, anti-top slips and load-bearing slips. Although the universal slips have the function of anti-top slips and load-bearing slips, but the clamping speed is slow, the clamping force is too small, and it cannot automatically compensate for the decrease in clamping performance caused by the slight leakage of hydraulic components, and the self-locking performance Poor (can only rely on hydraulic lock for self-locking) problem. Although the anti-top slips and load-bearing slips have fast clamping speed, large clamping force and good self-locking performance, they have large dimensions in the height direction and cannot seal the pressure in the well, so they can only be used for...

Problems solved by technology

Although the universal slips have the function of anti-top slips and load-bearing slips, but the clamping speed is slow, the clamping force is too small, and it cannot automatically compensate for the decrease in clamping performance caused by the slight leakage of hydraulic components, and the self-locking performance Poor (can only rely on hydraulic lock for self-locking) problem

Although the anti-top slips and load-bearing slips have fast clamping speed, large clamping force and good self-locking performance, they have large dimensions in the height direction and cannot seal the pressure in the well, so they can only be used for fixed slips and Swimming Kava

[0003] When the fixed slips and floating slips of the working device under pressure use anti-top slips or load-bearing slips, the distance from the floating slips to the righting limit of the oil pipe increases, and the oil pipe is prone to buckling, and the entire under pressure The height of the operating device increases, which leads to an increase in the height of the derrick of the workover rig, which affects the operation stability and transport stability of the equipment
