Abstract

The invention relates to a multi-specification pipeline flange rapid dismounting tool which can be used for simultaneously screwing tight multiple flange bolts and can be adapted to pipelines of different specifications. The technical scheme is as follows: frame rocks successively penetrate into the holes of connecting frame slide blocks and are locked and fixed by positioning screws so as to form a variable diameter mechanism. Long shaft shoulder wrench levers penetrate into intermediate sleeves of a group of frame rods which are arranged relatively at the back of a support, short shaft shoulder wrench levers penetrate into intermediate sleeves of a group of frame rods which are arranged relatively at the front of the support to form a working rotation portion so as to transmit torque to bolts; and at the other side of a flange, a pair of right angle fixation plates are used to form a working static portion so as to prevent the bolts from rotation in a screwing process. The multi-specification pipeline flange rapid dismounting tool is simple in structure and convenient to use.

Description

A kind of many size pipelines flange Quick disassembling tool

Technical field:

The present invention relates to one can tighten multiple flange bolt simultaneously, and one many size pipelines flange Quick disassembling tool of different size pipeline can be adapted to.

Background technology:

Reality engineering upper flange install connect time be all by manually bolt and nut one by one being tightened, in order to ensure sealing and the reliability of Flange joint, tighten centrosymmetric for nut, this mode is time-consuming but also effort not only, greatly reduce real work efficiency, we design and have invented a kind of many size pipelines flange Quick disassembling tool in view of the situation, can be simultaneously simultaneously fastening to multiple bolt, can the size of adjusting device by the position of adjusting slider on hack lever, can also be adapted to different flange size, versatility is stronger.

Summary of the invention:

The object of the invention is: multiple bolt is tightened simultaneously, by adjustment diameter changing mechanism, go for the flange size of multiple different size.

For reaching above object, the present invention by the following technical solutions: a kind of many size pipelines flange Quick disassembling tool is by hack lever, frame linking slide block, dog screw, major axis shoulder spanner loop bar, minor axis shoulder spanner loop bar and right angle, another side fixed head composition; Architectural feature is: hack lever penetrates in the hole of frame linking slide block in turn, is locked forms diameter changing mechanism by dog screw; Major axis shoulder spanner loop bar penetrates in the sleeve on support in the middle of a relative position shelving bar rearward, and minor axis shoulder spanner loop bar penetrates in the sleeve in the middle of the forward shelving bar of relative position on support, and composition work rotating part, operationally to bolt transmitting torque; Use a pair right angle fixed head composition work stationary part at the opposite side of flange, prevent screws tightening in process.

The invention has the beneficial effects as follows: (1) can make multiple bolt tighten simultaneously, reduce the workload of workman; (2) physical dimension is adjustable, can be applicable to the pipe flange of different size.

Detailed description of the invention:

With reference to the accompanying drawings shown in 3, a kind of many size pipelines flange Quick disassembling tool is by hack lever 6-A, 6-B.6-C, 6-D and frame linking slide block 8-A, 8-B, 8-C, 8-D connect to form diameter changing mechanism in turn, wherein frame linking slide block 8 is respectively provided with two dog screws 10, the relative position being used for fixing frame linking slide block 8 and hack lever 6 carrys out the size of governor motion; Major axis shoulder spanner headgear 7-A, 7-B, inserts relative position hack lever 6-C rearward on support respectively, in the intermediate sleeve of 6-D, minor axis shoulder spanner headgear 9-A, 9-B, inserts the forward hack lever 6-A of relative position respectively, in the intermediate sleeve of 6-B, composition work rotating part, is illustrated in figure 2 the schematic diagram under device duty, and its applicable flange conduit types of institute as shown in Figure 1, its pipe flange structure composition should have pipeline 1, bolt 2 nut 3 and flange plate 4; In use, first by right angle, another side fixed plate A 5, with right angle, another side fixed head B, 11 are contained in flange side, be used for fixing bolt, prevent screws, work rotating part is loaded onto in flange two side, when work rotating part is installed, first by hack lever 6-B and frame linking slide block 8-A and 8-D mounted thereto, and minor axis shoulder spanner headgear 9-A pulls down, after being filled by remainder on pipeline again, be loaded on hack lever 6-B and frame linking slide block 8-A and 8-D mounted thereto, and minor axis shoulder spanner headgear 9-A; By adjustment hack lever and the position being arranged on the corresponding component on hack lever, adjust plant bulk, make spanner cover, its four bolts hole that simultaneously can pack into flange are made to complete installation, when needing fastening bolt, the spanner headgear hexagonal end 12 of the rotating part that only needs to work again inputs certain torque.
