Abstract
The invention provides a pipe elevator. The pipe elevator comprises a left half portion and a right half portion which are in rotary connection; the left half portion and the right half portion comprise hanging rings, handles and semi-cylindrical through grooves; the hanging rings and the handles are symmetrically arranged on the outer lateral wall; the semi-cylindrical through grooves are symmetrically arranged on the inner lateral wall; the left half portion and the right half portion are fixed through a snapping device which comprises a fastener which is arranged on the left portion and a clamping groove which is formed in the right portion. The pipe elevator has the advantages of being simple in structure and operation and firm in connection.
Description
Technical field
The present invention relates to petroleum drilling and mining field of tool, especially relate to a kind of pipe elevator.
Background technology
Pipe elevator is in petroleum drilling and mining, to hoist or the special tool of the tubing string that declines, and is a kind of instrument of the tubing such as drilling rod, oil pipe and sleeve pipe that are used for slinging.It is suspended on the suspension ring the inside of Hoisting System hook both sides, to well is tripped out or is lowered to the operation of drilling tool and oil pipe, sleeve pipe.Existing pipe elevator is generally a moon dentition formula elevator, by elevator handle, pulls lift sub crescent to open and close back and forth.Due to the frequent switch of lift sub crescent, cause elevator handle pin loosening, the handle connecting bolt that makes to be connected with lift sub crescent rotates to move back buckle or comes off, and causes the lift sub crescent being attached thereto to come off, and affects and keeps the safety in production
Summary of the invention
The object of this invention is to provide a kind of simple in structure, simple to operate, connect firm pipe elevator.
Technical scheme of the present invention is:
Pipe elevator, comprise the left-half and the right half part that are mutually rotationally connected, described left-half and described right half part comprise suspension ring and the handle being symmetricly set on lateral wall, and be symmetricly set on the half-terete groove on inside wall, described left-half and described right half part are fixed together by clamping apparatus, described clamping apparatus comprises the buckle being arranged in described left-half, and is arranged on the draw-in groove on described right half part.
Described draw-in groove comprises the card-tight part matching with described buckle being rotationally connected with described right half part by torsion spring and the handle being rotationally connected by torsion spring and described card-tight part.
Also comprise handle, described handle is arranged on described left-half or described right half part.
The advantage that the present invention has with good effect is: simple in structure, simple to operate, be connected firm.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the cross-sectional structural representation of the use state of Fig. 1.
In figure:
1, left-half 2, right half part 3, handle
4, suspension ring 5, handle 6, groove
7, buckle 8, draw-in groove 9, card-tight part
10, handle
The specific embodiment
As Fig. 1, shown in Fig. 2, the present invention includes the left-half 1 and the right half part 2 that are mutually rotationally connected, with the handle 3 being arranged on described right half part 2, described left-half 1 and described right half part 2 comprise suspension ring 4 and the handle 5 being symmetricly set on lateral wall, and be symmetricly set on the half-terete groove 6 on inside wall, the columned through hole that the groove 6 of described both sides forms for clamping oil pipe, described left-half 1 and described right half part 2 are fixed together by clamping apparatus, described clamping apparatus comprises the buckle 7 being arranged in described left-half 1, with the draw-in groove 8 being arranged on described right half part 2.
Described draw-in groove 8 comprises by the card-tight part 9 that torsion spring is that be rotationally connected with described right half part 2 and described buckle 7 matches and the handle 10 that is rotationally connected by torsion spring and described card-tight part 9.
Above one embodiment of the present of invention are had been described in detail, but described content is only preferred embodiment of the present invention, can not be considered to for limiting practical range of the present invention.All equalization variations of doing according to the present patent application scope and improvement etc., within all should still belonging to patent covering scope of the present invention.
