Abstract
The utility model provides a lifting tool for a connecting casing, and relates to a device for lifting the connecting casing. The device is composed of the lifting tool for the connecting casing and a connecting lug plate, wherein the lug plate is installed on the inner side of the connecting casing, the lifting tool for the connecting casing is connected with the connecting lug plate, and the function that the connecting casing can be lifted on the inner side of the connecting casing is achieved. Lifting of the connecting casing is achieved. Meanwhile, pneumatic tyre unions are not damaged when the connecting casing is installed. The lifting tool for the connecting casing is reasonable in design, simple in structure, convenient and fast to install, strong in practicability and applicable to all types of petroleum drilling machines.
Description
Technical field
The present utility model relates to a kind of supporting accessory of oil-well rig, specifically a kind of splicing sleeve lifting appliance.
Background technology
Splicing sleeve is the important component part of oil-well rig, and its Main Function is for collecting mud liquid, and the generic connectivity sleeve pipe can perforate on casing wall, utilize shackle to lift assembling, be easy to like this scratch the pneumatic tyre union, cause the gas leakage of pneumatic tyre union, affect its sealing performance.
The utility model content
Purpose of the present invention is exactly for above deficiency, and a kind of splicing sleeve hoisting tool reasonable in design, simple in structure, quick and easy for installation is provided, when it can avoid splicing sleeve to install effectively to the damage of pneumatic tyre union.
The concrete technical scheme of the utility model is: by the hoisting tool body be connected otic placode and form, described hoisting tool body comprises the uniform linking arm in lifting arm and its underpart, the lifting otic placode that top is provided with, and described linking arm be connected otic placode and match.
The end of described linking arm is provided with round steel, and be connected otic placode and match.
Splicing sleeve hoisting tool of the present invention is compared with the hoisting tool that uses in the past, has following remarkable advantage:
1, whole consideration makes things convenient for the installation of splicing sleeve;
2, effectively protect the pneumatic tyre union, prevent that the pneumatic tyre union is damaged, affect its sealing;
3, the assembling of splicing sleeve hoisting tool and splicing sleeve is simple, convenient, does not need operating personnel's work high above the ground, Effective Raise drill-well operation personnel's processing safety.
Description of drawings
Fig. 1 is the structural representation of hoisting tool body in the utility model;
Fig. 2 is the scheme of installation that connects otic placode in the utility model;
Wherein: 1, lifting arm, 2, linking arm, 3, round steel, 4, the lifting otic placode, 5, connect otic placode, 6, splicing sleeve.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Referring to Fig. 1-2, a kind of splicing sleeve hoisting tool, by the hoisting tool body be connected otic placode 5 two parts and form, the hoisting tool body comprises the uniform linking arm 2 in lifting arm 1 and its underpart, the lifting otic placode 4 that top is provided with, the end of linking arm 2 is provided with round steel 3, and be connected otic placode 5 and match.
During use, to connect otic placode 5 and be installed on splicing sleeve 6 inboards, the splicing sleeve hoisting tool by its round steel 3 be connected otic placode 5 and connect, namely make things convenient for splicing sleeve to install, dismantle, and hoisting tool and splicing sleeve are easy to connect, only need to get final product rotating in hoisting tool placement and the splicing sleeve, do not need operating personnel to enter and carry out dismantlement work in the sleeve pipe, guaranteed operating personnel's personal safety.
The above is preferred embodiment of the present utility model; should be noted that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; might be to concrete size; perhaps partial structurtes go out some improvements and modifications, and these improvements and modifications also should be considered as protection domain of the present utility model.
