1. whole slips base exterior size is too large, causes product own wt large on the one hand, wastes time and energy in workman's use procedure, enters in casing head body process on the other hand and easily blocked by preventer flange face under this slips hanger;
2. in traditional slip spider use procedure, easily there is relative sliding in sleeve pipe and hanger, and slip spider can not be made firmly to be fixed on sleeve pipe;
3. traditional slip spider produces hanger and sleeve pipe rotates in the tight shackle process of sleeve pipe.
Summary of the invention
The technical problems to be solved in the utility model is for the weak point existing for prior art, a kind of slips hanger is provided, this hanger arranges Rouno Cormer Pregrinding Wheel bottom slip spider, both deadweight was alleviated, operative is time saving and energy saving, also save material simultaneously, reduce costs, to enter in casing head body process easily by problem that preventer flange face blocks under efficiently solving slips hanger, employing symmetrical structure designs, with bolts after assembling, improve bonding strength, effectively prevent sleeve pipe and hanger from easily relative sliding occurring, position block is welded in slip spider cannelure, prevent slip spider from the tight shackle process of sleeve pipe, producing hanger and sleeve pipe rotates, product uses more safe and reliable.
Technical solution of the present utility model is, following a kind of slips hanger is provided, comprise slip spider, described slip spider is made up of two pieces of symmetrically arranged slip spiders of semi-circular, form the annular slip spider of a centre with installing hole after installing splicing, be provided with slips in the installing hole in the middle of described slip spider, described slip spider top is provided with packing lower gasket, described packing lower gasket top is provided with rubber packing, and described rubber packing top is provided with packing upper gasket.
As preferably, the middle and lower part of described slip spider outer wall is provided with chamfering.Adopt the technical program, both alleviated deadweight, operative is time saving and energy saving, also saves material simultaneously, reduces costs, and enters the problem blocked by preventer flange face in casing head body process under efficiently solving slips hanger.
As preferably, described slip spider, packing lower gasket, rubber packing, packing upper gasket are fixedly connected with by screw with slips.Adopt the technical program, structure is simple, and bonding strength is high, is convenient to demolition and maintenance, easy to use.
As preferably, described installing hole top is provided with the annular protrusion of inside protrusion, and middle part is provided with the slips fixed groove of outwards depression, and bottom is provided with to projecting inward limited block.Adopt the technical program, form an intermediate annular size large, the project organization that two ends annular size is little, treasured prevents slips from moving up and down, and serves restriction effect, also effectively prevent slips simultaneously and departs from from slip spider, and structure is simple, easy to use.
As preferably, described slip spider, packing lower gasket, rubber packing, packing upper gasket are provided with through hole, and described slips is provided with screwed hole.Adopt the technical program, utilize coordinating of screw and screwed hole, slip spider, packing lower gasket, rubber packing, packing upper gasket and slips are linked together, structure is simple, and easy to use, bonding strength is high, convenient disassembly, is convenient to maintenance.
As preferably, the through hole that described packing upper gasket is provided with is the through hole with countersunk head.Adopt the technical program, can effectively prevent from the end of screw to be exposed producing with miscellaneous part interfering, structure is simply, easy to use.
As preferably, described slip spider is provided with the bolt for locking two pieces of symmetrically arranged slip spiders of semi-circular.Adopt the technical program, be locked by two pieces of symmetrically arranged slip spiders of semi-circular, form an integrative-structure, bonding strength is high, and demolition and maintenance are convenient.
As preferably, described slip spider outer wall surface is provided with ring-shaped groove, is welded with block in described ring-shaped groove, and described block is two groups, and is arranged symmetrically with.Adopt the technical program, in slip spider cannelure, weld position block, prevent slip spider from the tight shackle process of sleeve pipe, producing hanger and sleeve pipe rotates, product use is more safe and reliable.
Adopt the beneficial effects of the utility model: this hanger arranges Rouno Cormer Pregrinding Wheel bottom slip spider, both deadweight was alleviated, operative is time saving and energy saving, also save material simultaneously, reduce costs, to enter in casing head body process easily by problem that preventer flange face blocks under efficiently solving slips hanger, employing symmetrical structure designs, with bolts after assembling, improve bonding strength, effectively prevent sleeve pipe and hanger from easily relative sliding occurring, position block is welded in slip spider cannelure, prevent slip spider from the tight shackle process of sleeve pipe, producing hanger and sleeve pipe rotates, product uses more safe and reliable.
