Abstract
The utility model relates to a hoisting sling for a pipeline. The hoisting sling comprises a chain block, a cylinder body, a piston rod and a spring, wherein the chain block and the cylinder body are connected, one end of the spring is contacted with the cylinder body, the other end of the spring is contacted with the piston rod, one end of the piston rod is connected with a rotary lever which is connected with two gripper arms through connecting rods, the gripper arms are connected with a center support through a pin roll, the center support is connected with the cylinder body, and two workpieces are arranged between the gripper arms and the center support. The hoisting sling has a simple structure and reasonable design; due to the match of the piston rod and the spring, the gripper arms can stably grab the cylindrical pipeline, so that the pipeline is convenient to hoist and transport; as the gripper arms and the center support are arranged in a V-shaped structure, cylindrical pipelines of various diameters are convenient to place, and the application range of the hoisting sling is enlarged.
Description
Technical field
The utility model relates to mechanical field, relates in particular to the Current Collector Sleave that a kind of pipeline is used.
Background technology
Along with scientific and technical development, requirement for safety is also more and more higher, because drilling rod, the lifting of steel pipe does not have special-purpose suspender, make the slinger of drilling rod and steel pipe operate 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, after on the crossbeam that steel rope can only be hung over during construction, hang jack, the steel grating that so just need to dismantle and lay on crossbeam, dismantle and also will set up safe fence after steel grating and lay safety net, and wirerope-winding wear area to crossbeam on crossbeam is larger, after having lifted, also to resume operation.This mode is inefficiency not only, consumes one's strength, and has very large potential safety hazard, and therefore, for addressing the above problem, spy provides a kind of new technical scheme.
Utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, the Current Collector Sleave that provides a kind of pipeline to use.
The utility model is to be achieved through the following technical solutions:
The Current Collector Sleave that a kind of pipeline is used, 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 of matching with chela in described center support is v-shaped structure.
Compared with prior art, the beneficial effects of the utility model are: the utility model is simple in structure, reasonable in design, by coordinating of piston rod and spring is set, can make chela steadily catch cylindrical pipe, be convenient to like this lifting and the transportation of pipeline; By be set to v-shaped structure in chela and center support, be convenient to the placement of the cylindrical pipe of various diameters, thereby improved the range of use of Current Collector Sleave.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
The Current Collector Sleave that a kind of pipeline is used, 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 contact with cylinder body 2, the other end contacts with piston rod 7, described piston rod 7 one end are 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 that the stress on chela 4 is concentrated, described center support 6 is connected with cylinder body 2, and the position of matching with chela 4 in described center support 6 is v-shaped structure, be convenient to the placement of the cylindrical pipe of various diameters, thereby improved the range of use of Current Collector Sleave.Between described chela 4 and center support 6, be provided with two workpiece 5.
To sum up, the utility model is simple in structure, reasonable in design, by coordinating of piston rod and spring is set, can make chela steadily catch cylindrical pipe, be convenient to like this lifting and the transportation of pipeline; By be set to v-shaped structure in chela and center support, be convenient to the placement of the cylindrical pipe of various diameters, thereby improved the range of use of Current Collector Sleave.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
