Abstract
The utility model discloses a kind of telescope pole top and drive tensioning apparatus, be provided with hydraulic tensioning cylinder in outer derrick bottom, by hydraulic cylinder tensioning wire rope, wire rope is connected to top and drives on the lower end eye plate of support by being fixed on pulley on internal layer derrick, stretch to realize pushes up the tensioning of driving by fluid cylinder.Tensioning apparatus is driven on derrick of the present utility model top, is connected to and pushes up a series of interlock of driving on support by hydraulic cylinder tensioning wire rope and by pulley, and operator just can complete top by operating grip and drive tensioning in driller house, simple in structure, safe and reliable, easy to operate, and manufacturing cost is lower.
Description
Technical field
The utility model belongs to petroleum machinery technical field, relates to a kind of telescope pole top and drives tensioning apparatus.
Background technology
Telescope pole, adopts fluid cylinder to promote, and realizes the relative motion of ectonexine derrick, realizes pushing up to drive moving up and down.The Hoisting System of tradition derrick needs high-power winch and complicated traveling system, easy to operate.This type derrick Integral transporting performance is good, and this drill top-drive Hoisting System is used to hydraulic drill rig.Tensioning apparatus is driven on top,, after installation is driven on top on telescopic derrick, the device of tensioning is driven in top, improve when the stress of driving wire rope in top is driven work on top simultaneously and do not bear while carrying compared with hook, also can push up the accurate location of driving flexible realization of derrick, be the very important some of telescopic derrick, require its work necessary safe and reliable.
Summary of the invention
The purpose of this utility model is: design a kind of telescope pole top and drive tensioning apparatus, top is driven with derrick and steadily move, improve because wire rope stress is driven on top, improve the application life of wire rope, the accurate control of position is driven on realization top simultaneously.
Technical solution adopted in the utility model is: tensioning apparatus is driven on the top of designing a hydraulic tensioning cylinder wire rope and pulley composition, adopt hydraulic-driven hydraulic tensioning cylinder and by wire rope transfers tensile force, change tension direction realization top by pulley and drive tensioning.
The beneficial effects of the utility model are: it is more steady that the utility model makes top drive motion, improves derrick wire rope stress, make top drive work safety and reliability, and it is more accurate that Position Control is driven on top.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Fig. 1 and Fig. 2 are structural representation of the present utility model.
Fig. 3 and Fig. 4 are detailed drawing of the present utility model.
Detailed description of the invention
As shown in Figure 1 and Figure 2, be provided with tensioning fluid cylinder on the outer top of derrick, tensioning fluid cylinder 1 is connected with the pulley 4 on internal layer derrick successively by wire rope 3, and wire rope drives support 2 by eye plate and bearing pin with top and is connected.In the time of 1 tensioning of tensioning fluid cylinder, by wire rope 3 and pulley 4, tensile force is delivered to top and drives on support 2, realize the tensioning that drive on top.
Be understandable that, above about specific descriptions of the present utility model, only for the utility model is described not first with the described technical scheme of the utility model embodiment, thump the technician of this area is to be understood that, still can modify or be equal to replacement the utility model, reach identical technique effect; As long as meet practical needs, all within protection domain of the present utility model.
