Abstract

The utility model discloses a hydraulic drill rod slip. The hydraulic drill rod slip comprises a slip frame, wherein a base is arranged on the slip frame. The hydraulic drill rod slip is characterized in that suckers are arranged at the periphery of the slip frame, an insurance hook is arranged on the base, and a limiting device is further arranged at the bottom of the base. The hydraulic drill rod slip has the advantages of being reasonable in structure, large in elevating power, wide in clamping range, and capable of being adaptive to different well drilling conditions.

Description

A kind of hydraulic drilling rod slips
Technical field
The utility model relates to a kind of device that holds drilling rod for the oil and gas well drilling operation.
Background technology
The instrument that holds drilling rod in existing oil, natural gas operation mainly contains: 1, manual drill pipe slip, and the multiple-piece structure, volume is large, and weight is large, and labor strength is large, and inefficiency and safety are not high; 2, air spider can realize the automatic lifting of slips body, but this device volume is huge, and is arranged on the rotating disk top, makes complete machine height distance plane of rotor disc higher, and using to hydraulic tongs makes troubles; 3, air operated slips can be realized the slips automatic lifting, and is arranged in rotating disk, has saved the space, but well head bad use too partially the time, and the phenomenon that in the shallow well operation, well head departs from happens occasionally, and brings certain limitation for the use of air operated slips.
The utility model content
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and lifting force is large, holds scope wide, can adapt to the hydraulic drilling rod slips safe and reliable, easy and simple to handle of different drilling conditions.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of hydraulic drilling rod slips comprises: the slips frame, and described slips frame is provided with base, wherein, and the outer sucker that is arranged with of described slips frame, described base is provided with auxiliary catch, and base bottom also is provided with stopping means.
As preferred version, the sucker of described slips frame periphery is provided with two, and described two suckers are oppositely arranged on the slips frame.
As preferred version, described slips frame also comprises connecting rod, suspension rod and arbitrary-movement articulator.
As preferred version, described stopping means is limited block or spacer pin.
As preferred version, also comprise hydraulic mechanism, described hydraulic mechanism is comprised of hydraulic line and 2 hydraulic cylinders.
The beneficial effects of the utility model are mainly reflected in: rational in infrastructure, lifting force is large, holds scope wide, can adapt to different drilling conditions.
Description of drawings
Fig. 1 is lateral view of the present utility model;
Fig. 2 is top view of the present utility model.
The specific embodiment
Referring to accompanying drawing 1 and Fig. 2, a kind of hydraulic drilling rod slips, comprise: slips frame 1 is comprised of base 101, auxiliary catch 105 and powerful electromagnetic chuck 106 etc., connecting rod 102, suspension rod 103 and arbitrary-movement articulator 104 consist of hoisting mechanism jointly, control the lifting of slips body 2 and transfer by the hydraulic control system 3 that is comprised of two hydraulic cylinders 301 and hydraulic line 302.2 powerful electromagnetic chucks 106 make whole hydraulic pressure pipe slips firmly be adsorbed on rotating disk and mend on core.It is more firm that the design of 2 powerful electromagnetic chucks makes whole hydraulic pressure pipe slips and rotating disk benefit core be connected, and uses safer.After the slips body rises to the extreme higher position, the safety device of the compositions such as auxiliary catch 105 can automatically lock, safety device mainly is comprised of insurance limited block, auxiliary catch, Compress Spring and fixed pin shaft etc., auxiliary catch is connected with slips frame base by fixed pin shaft, the insurance limited block is welded on the slips frame, the slips frame promotes drive insurance limited block and is rotated counterclockwise, then hook with auxiliary catch, effect hook by Compress Spring is dead, when requiring slips to transfer to hold tubing string, the operator must tramp with one's feet and can carry out other operations after lower safety device.Hydraulic control system 3 is comprised of 2 hydraulic cylinders 301 and hydraulic line 302 etc.Base 101 bottoms are provided with limited block 107, and limited block 107 can adapt to pin driving rotating disk benefit core or the four directions drives the use that rotating disk is mended core by changing.
In sum, it is only preferred embodiment of the present utility model, be not to limit the scope that the utility model is implemented, all equalizations of doing according to the described shape of the utility model claim scope, structure, feature and spirit change and modify, and all should be included in claim scope of the present utility model.
