Abstract
The invention relates to a wire rope sling. The wire rope sling comprises a chain block, a cylinder body, a piston rod and springs, wherein the chain block is connected with the cylinder body; one ends of the springs contact the cylinder body, and the other ends of the springs contact the piston rod; one end of the piston rod is connected with a rotation lever connected with two gripping jaws by a connecting rod; the gripping jaws are connected with a central support via pin shafts; the central support is connected with the cylinder body; two workpieces are arranged between the gripping jaws and the central support. The wire rope sling is simple in structure and is reasonable in design; the piston rod and the springs are matched, so that the gripping jaws can stably grip the cylindrical pipeline, so that the pipeline is convenient to lift and transport; the gripping jaws and the central support are provided with V-shaped structures, cylindrical pipelines with various diameters can be conveniently placed, so that the use range of the wire rope sling is widened.
Description
Technical field
The present invention relates to mechanical field, particularly relate to a kind of Current Collector Sleave of pipeline.
Background technology
Along with the development of science and technology, requirement for safety is also more and more higher, because drilling rod, the lifting of steel pipe does not have special suspender, the slinger of drilling rod and steel pipe is operated loaded down with trivial details, inefficiency, simultaneously, owing to needing to lift with jack in work progress center member and pillar process in place, staff is substantially in aloft work state, jack is hung after on the crossbeam that steel rope can only be hung over during construction, so just need to dismantle the steel grating that crossbeam is laid, dismantle and also will set up safe fence after steel grating and lay safety net, and wirerope-winding is larger to the wear area of crossbeam on crossbeam, also to resume operation after having lifted.This mode not only inefficiency, consumes one's strength, and there is very large potential safety hazard, and therefore, for solving the problem, spy provides a kind of new technical scheme.
Summary of the invention
The object of the invention is, in order to overcome the deficiencies in the prior art, to provide a kind of Current Collector Sleave of pipeline.
The present invention is achieved through the following technical solutions:
A kind of Current Collector Sleave of pipeline, comprise jack, cylinder body, piston rod, spring, described jack is connected with cylinder body, described spring one end contacts with cylinder body, and the other end contacts with piston rod, and described piston rod one end is connected with pivoted lever, described pivoted lever is connected with two chelas by connecting rod, described chela is connected with center support by bearing pin, and described center support is connected with cylinder body, is provided with two workpiece between described chela and center support.
As preferably, described pivoted lever is fixedly connected with piston rod.
As preferably, one end of described chela is v-shaped structure, and described chela is provided with stress hole.
As preferably, the position that described center support matches with chela is v-shaped structure.
Compared with prior art, the invention has the beneficial effects as follows: structure of the present invention is simple, reasonable in design, by arranging coordinating of piston rod and spring, can make chela steadily catch cylindrical pipe, be convenient to the hoist&transport equipment of pipeline like this; By being set to v-shaped structure on chela and center support, be convenient to the placement of the cylindrical pipe of various diameter, thus improve the range of use of Current Collector Sleave.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Refer to Fig. 1, Fig. 1 is structural representation of the present invention.
A kind of Current Collector Sleave of pipeline, comprise jack 1, cylinder body 2, piston rod 7, spring 8, described jack 1 is connected with cylinder body 2, described spring 8 one end contacts with cylinder body 2, the other end contacts with piston rod 7, described piston rod 7 one end is connected with pivoted lever 3, and described pivoted lever 3 is fixedly connected with piston rod 7.Described pivoted lever 3 is connected with two chelas 4 by connecting rod, described chela 4 is connected with center support 6 by bearing pin, one end of described chela 4 is v-shaped structure, described chela 4 is provided with stress hole 40, can prevent the stress on chela 4 from concentrating, described center support 6 is connected with cylinder body 2, and the position that described center support 6 matches with chela 4 is v-shaped structure, be convenient to the placement of the cylindrical pipe of various diameter, thus improve the range of use of Current Collector Sleave.Two workpiece 5 are provided with between described chela 4 and center support 6.
To sum up, structure of the present invention is simple, reasonable in design, by arranging coordinating of piston rod and spring, can make chela steadily catch cylindrical pipe, be convenient to the hoist&transport equipment of pipeline like this; By being set to v-shaped structure on chela and center support, be convenient to the placement of the cylindrical pipe of various diameter, thus improve the range of use of Current Collector Sleave.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
