Description
Technical field
The utility model relates to a kind of flange strutting tools.
Background technique
Supply water or the maintenance work of heat supply pipeline in be related to the replacement of valve, water meter, since pipeline expands with heat and contract with cold and water
Hitting the reasons such as effect is subjected to displacement pipeline, thus valve or water meter by the mounting flange card at both ends obtain it is very tight, remove when very
It is difficult.Usually the gap between valve flanges and mounting flange prized with crowbar in the prior art it is big, while with iron hammer by valve
Or water meter is pounded；It generally also pounds in sled when installation and fills in valve firmly, then again with hydraulic spreader by Method for Installation
Gap enlargement between blue and valve flanges is added gasket and screws on installation screw and installed.But this method maintenance effect
Rate is low, labor intensity of operating staff is big；Furthermore there are larger security risks for violence dismounting, and operation is also relatively more tired when narrow space
Difficulty sometimes has to employ electrogas welding progress welding operation, reinstalls pipeline, valve or water meter.
Authorization Notice No. is that the Chinese utility model patent of CN201736191U discloses a kind of pipeline valve dismounting device,
It is made of left hoop, left steel ring, right steel ring, right hoop, screw rod, left fixture block, nut, right fixture block, left fixture block is stuck in left card
It binding round between head, valve, right fixture block is stuck between right hoop, valve, and nut is spun on screw rod, and screw rod left end passes through left fixture block,
Screw rod right end withstands right fixture block, and nut is between left fixture block, right fixture block.The device makes left hoop, the right side by rotating nuts
The distance between hoop increase, make to a certain extent dismantle pipeline valve it is convenient, fast, reduce labor intensity of workers,
It improves work efficiency；But need to take measures to fasten screw rod in operation and do not allow it with nut turn, operation is still more troublesome,
Arduously；And in the nut turn later period, as the friction between nut and fixture block is increasing, serious wear between nut and fixture block,
And part is not easy to store, easy to be lost.

The second threaded hole 6 that the 1 anti-screw thread thread segment in the right of lead screw screws in；Left fixture block 2 and right fixture block 3 are equipped with certain thickness lower claw
7, the thickness of lower claw 7 is determined according to the flange size used, to ensure that lower claw 7 can be stuck in flange slot when dismantling valve
It is interior；The escape groove of evacuation flange installation screw rod is additionally provided on fixture block and lower claw 7.1 both ends of lead screw in the flange strutting tool
Fixture block may also be used in which that a fixture block and 1 screw-driven of lead screw cooperate, and another fixture block and lead screw 1 are rotatably assorted and along axial gear
The structure only cooperated, such as the end of lead screw is passed through into fixture block, and be arranged on lead screw in the two sides of fixture block and match with fixture block block
The pin shaft of conjunction realizes that fixture block and lead screw 1 are rotatably assorted and cooperate along axial block, and being also able to achieve only rotational lead screw 1 can increase
The effect of distance between two fixture blocks.In the present embodiment, the tool cooperation section is rectangular section 4；The flange strutting tool uses
Tool cooperates the structure that section section is rectangle relatively simple convenient for the clamping of twisting tool, easy to process and operation；Herein on lead screw 1
Tool cooperates the section of section that can also be other shapes, such as hexagon, is equally applicable to the clamping of twisting tool.
In addition, the anti-torsion hole 9, Zuo Ka of quadrangle is additionally arranged on the left fixture block 2 and right fixture block 3 in the present embodiment
The left side of block 2 and right fixture block 3 further respectively has the first threaded hole 5 and the second threaded hole 6, the jackscrew being used cooperatively with threaded hole
11 are equipped with external screw thread；Anti- torsion sliding rail 10 is installed in anti-torsion hole 9, the anti-torsion sliding rail 10 cooperates with fixture block rotation stop guiding；
The flange strutting tool can effectively prevent both ends in 1 rotation process of lead screw using anti-torsion hole 9 and the anti-structure for turning round sliding rail 10 is added
Fixture block stress reverses the generation to fall off.It equally may also be used in which herein and add anti-torsion hole 9 on a fixture block and be wherein installed with anti-
The structure for turning round sliding rail 10 can equally play the phenomenon that effectivelying prevent the fixture block stress torsion of rotation stop guiding cooperation to fall off.
As shown in figure 5, the left side of left fixture block 2 and right fixture block 3 is equipped with third threaded hole 12, peace in third threaded hole 12
Equipped with the jackscrew 11 being threadedly engaged therewith, jackscrew 11 is screwed in left fixture block 2 and the threaded hole of the respective left side of right fixture block 3, it will
One of jackscrew 11 presses against on the anti-torsion sliding rail 10 for being inserted into left fixture block 2 or right fixture block 3, another jackscrew 11 and anti-torsion sliding rail
10 keep certain interval, and fixture block slides on anti-torsion sliding rail 10 when strutting valve flanges to facilitate.Herein also optional wherein one
The anti-threaded hole for turning round hole 9 of setting connection on a fixture block left side or one or more sides of upper side or downside,
Multiple threaded holes can be set on above-mentioned side, and be fitted with for being fixed the anti-jackscrew 11 for turning round sliding rail 10, equally
1 turn of lead screw can be played, effect is fixed to anti-torsion sliding rail 10 in the process；Screw thread can be added on another described fixture block
Hole does not set threaded hole, or adds threaded hole and be unworthy of top set silk 11.
The utility model use process is as follows: when the tool assemble, by left fixture block 2 and right fixture block 3 respectively from 1 liang of lead screw
End screws in rotation, until being screwed into the middle part of lead screw 1；Anti- torsion sliding rail 10 is inserted into the anti-torsion hole 9 of left fixture block 2 and right fixture block 3 again
In, then jackscrew 11 is screwed in the left side threaded hole of left fixture block 2 and right fixture block 3, one of jackscrew 11 is pressed against anti-
It turns round on sliding rail 10, another jackscrew 11 and anti-torsion sliding rail 10 keep certain interval, block accordingly when in order to strut valve flanges
Block can slide on anti-torsion sliding rail 10；Then with tool cards such as spanners in the rectangular section 4 at 1 middle part of lead screw, rotational lead screw 1 makes a left side
Fixture block 2 and right fixture block 3 are mobile to 1 both ends of lead screw, when the distance between left fixture block 2 and right fixture block 3 reach the method for valve to be installed
When blue width, the lower claw 7 of the lower claw 7 of left fixture block 2 and right fixture block 3 is stuck in the left and right flanges piece of valve to be installed
Inside, be further continued for rotational lead screw 1, the width top that will install the left and right flanges piece of valve is big, to meet installation valve and close
The width requirement of gasket.The tool operation is simple, is only needed when strutting, dismantling using tool cards such as spanners at 1 middle part of lead screw
Rectangular section 4 is rotated, that is, can reach the effect for strutting valve flanges distance, significantly reduces labor intensity and construction is strong
Degree, and lower construction of removing stage makeup and costume suitable for restricted clearances such as valve well or water meter chambers is required operating space；Maintenance efficiency
Height, coefficient of losses are lower and easily stored.
The specific embodiment two of the utility model flange strutting tool, as shown in Figure 3, Figure 4, it is different from embodiment one it
