Description

The device that a kind of casing centralization is fixing

Technical field

This utility model relates to pipe location and installation field, particularly relates to the device that a kind of casing centralization is fixing.

Background technology

Existing conventional standpipe through-flooring sleeve pipe seldom uses fixing technology placed in the middle, is generally to block Journey, by the distance of ruler measurement sleeve pipe to standing tube outer wall whether as, and then fix between two parties.The fixing side of traditional casing centralization Although method plays a role to casing centralization is fixing, but this method is in actual mechanical process, needs repetitive measurement Lose time；And owing to lacking fixation during reality blocks, sleeve pipe can rock, ultimately result in axiality Not.Once sleeve pipe has blocked, and the deviation of generation would become hard to be modified again, and can only dismantle and reinstall.

Utility model content

The purpose of this utility model is that providing a kind of is quickly centered about sleeve pipe the fixing device being fixed.

Technical solution adopted in the utility model is:

The device that a kind of casing centralization is fixing, including handle with by hinged two swingles of the intersection on handle, institute Stating intersection and be provided with clamping screens, described intersection, between handle both ends, swingle described in two also is provided with clamp screens, Swingle described in two crosses along handle center's axis symmetrical expansion equal angular, the retaining wedge distance of positions on swingle described in two Place is equidistant.

Being further used as the improvement of technical solutions of the utility model, the centre of handle and two swingles is equipped with chute.

Being further used as the improvement of technical solutions of the utility model, clamping screens includes two be vertically installed on chute The bolt that can move along chute and the nut of correspondence.

It is further used as the improvement of technical solutions of the utility model, each chute is labeled with scale.

The beneficial effects of the utility model: the device that this casing centralization is fixed is by handle and two swingles and three groups of clampings Card potential energy produces six limit points so that this device can the most coaxially position double pipe；Held by handle and clamping screens Care set pipe, thus rocking of producing during counteracting closure, it is possible to stable double pipe axialities.

Accompanying drawing explanation

The utility model is described in further detail below in conjunction with the accompanying drawings:

Fig. 1 is the integral installation structure chart of this utility model embodiment；

Fig. 2 is the structure drawing of device that the casing centralization of this utility model embodiment is fixing.

Detailed description of the invention

With reference to Fig. 1, Fig. 2, the device installation environment that this casing centralization is fixed includes mounted standpipe 4 and is enclosed within standpipe 4 The sleeve pipe 3 to be installed of outside.The fixing device of casing centralization include handle 5 and by the intersection 8 on handle 5 hinged two Swingle 6；It is provided with clamping screens 2 at intersection 8, two swingles 6 also is provided with clamp screens 2；Clamping screens 2 includes two groups Bolt and nut, both form the structure of U-shaped like groove, and two bolts individually can slide respectively on chute 7, can reversely move The outer wall of rear gripping sleeve 3；Two swingles 6 respectively can be independently rotated around intersection 8, and after above-mentioned three assembling, structure is as Y shape Support.Described handle 5 and two swingles 6 are all prefabricated with chute 7, and described chute 7 is used for installing clamping screens 2.As in figure 2 it is shown, Wherein on handle 5, a bolt group of intersection 8 is mainly used in location and fixes two swingles 6, and by two swingle 6 end bands Dynamic its moves；Another root is the most movable, for being matched for clamping tightly the cross section annulus of sleeve pipe 3 with corresponding bolt.On described chute 7 also There is scale 9, it is simple under the different mounting condition of record, clamp the scale value of screens 2 correspondence.

The device that casing centralization after correctly installing and using is fixed is as it is shown in figure 1, two swingles 6 are along handle 5 central axis Symmetrical expansion equal angular, the clamping screens 2 on swingle 6 described in two is equidistant away from intersection 8.Grasp by holding handle 5 Making, handle 5 one end contact standpipe 4 with two swingle 6 inner side edges, and three groups on handle 5 and two swingles 6 clamp screens 2 simultaneously Block and be enclosed within the outer wall of sleeve pipe 3 outside standpipe 4.Placement Y shaped bracket is to relevant position, by early fixed three limit points 1 Can promptly be centered about sleeve pipe 3 with three clamping screens 2, its geometrical principle is at 3 and determines a plane, and 3 really A fixed center of circle；This device support sleeve pipe 3 simultaneously, closely counteracts rocking of closure process generation, makes installation rear profile tube 4 and set Pipe 3 axiality is guaranteed.

As this utility model preferred embodiment, as it is shown in figure 1, two swingles 6 generally ensure that end is fixed on friendship At remittance 8, intersection 8 regulate its position, angular relationship.So, two swingles 6 seem symmetrical, attractive in appearance, particularly scale 9 energy Enough show contrast number the most intuitively.

As this utility model preferred embodiment, during practice of construction, its operational approach includes:

A) first according to model, the limit point 1 between standpipe 4 and sleeve pipe 3 and the scale of clamping screens 2 are adjusted by chute 7 Value；

Clamping screens 2 scale value is directly adjusted when b) then using

C) the clamping screens 2 as U-lag is buckled in the outer wall of sleeve pipe 3, adjusts handle 5 and contacts with the limit point 1 of two swingles 6 Standpipe 4；

D) by two bolts against, make clamping screens 2 fasten the outer wall of sleeve pipe 3.

Certainly, this utility model is created and is not limited to above-mentioned embodiment, and those of ordinary skill in the art are not disobeying Also can make equivalent variations or replacement on the premise of back of the body this utility model spirit, the modification of these equivalents or replacement are all contained in this In application claim limited range.
