The utility model relates to a skirt bolt hole is apart from verifying attachment, including hollow survey buret, fixing bolt, clench nail and flexible pipe, flexible pipe is through the fixed flexible distance of at least one clench nail, flexible pipe both ends are equipped with the fixing bolt that the flexible pipe of perpendicular to set up, establish the hollow survey buret of screw thread in the last cover of fixing bolt has, the flexible nest of tubes becomes the hollow pipe box including tube core and tube core both ends, through the flexible pipe range degree of the relative slide adjusting between tube core and pipe box, two pipe boxes are fixed on the tube core through at least one clench nail respectively. Through using the utility model discloses a device, can be accurate precision and the upper and lower hole of device in different pitch -rows such as inspection skirt bolt hole distance, level gauge and the aperture straightness that hangs down, avoid the quality problems of on -the -spot installation.

Description

Skirt bolt hole is away from verifying attachment

Technical field

This utility model is related to chemical industry equipment manufacture field, and in particular to a kind of tower skirt bolt hole is away from inspection dress Put.

Background technology

Field is manufactured in chemical industry equipment, it is very high away from required precision to skirt bolt hole, ± 2mm is usually required that, but in reality Assembling and checkout procedure in, due to skirt ring flat-plate and base plate with skirt barrel soldering, reviewer cannot direct measurement go out Assembling rear skirt seat ring crab bolt pitch-row, is typically only capable to the pitch-row with tape measure skirt base plate, and the pitch-row of measurement ring flat-plate indirectly. The method may cause measurement tolerance bigger than normal because of cylinder ovality and cylinder heat treatment deformation.

The content of the invention

To solve the problems, such as above-mentioned prior art, this utility model provides a kind of simple structure, portable, and can The skirt bolt hole of the different pitch-rows of inspection and pore size is away from verifying attachment.

To realize above-mentioned technical purpose, this utility model is adopted the following technical scheme that：

A kind of skirt bolt hole is away from verifying attachment, including hollow measurement pipe, fixing bolt, fastening nail and telescoping tube；It is described Telescoping tube is by the fixed distance of stretch out and draw back of at least one fastening nail；Telescoping tube two ends are provided with the fixed spiral shell arranged perpendicular to telescoping tube Bolt, is cased with the interior hollow measurement pipe for setting screw thread on fixing bolt.

As it is of the present utility model further preferably, the telescoping tube composition includes the hollow pipe at tube core and tube core two ends Set, by the flexible length of tube of relative slidable adjustment between tube core and pipe box, described two pipe boxes are respectively by least one fastening Nail is fixed on tube core.

As it is of the present utility model further preferably, described two pipe boxes are respectively provided in telescoping tube shrinkage direction side Few fastening nail, at least one fastening are followed closely in same vertical plane, along the radially uniform distribution of pipe box.

As it is of the present utility model further preferably, described two pipe boxes are respectively provided with three in telescoping tube shrinkage direction side Individual fastening nail, three fastenings nail are located in same vertical plane, along the radially uniform distribution of pipe box.Followed closely using three fastenings Optimal fixed effect can be obtained in the case where fastening nail consumption is minimum.

As it is of the present utility model further preferably, the tube core is detachable.According to the difference of skirt diameter, can be more Change various sizes of tube core.

As it is of the present utility model further preferably, the tube core is the hard materials such as steel pipe, engineering plastics or carbon fiber Material.

As of the present utility model further preferred, it is characterised in that the hollow measurement pipe is detachable.According to treating The difference of skirt bolt internal diameter is surveyed, the hollow measurement pipe of various outer diameter is changed.

By using device of the present utility model, can accurately check skirt bolt hole away from the different pitch-rows such as, liquidometer and The precision of the device in aperture and upper and lower hole perpendicularity, it is to avoid the quality problems of field-mounted process.

Specific embodiment

The technical solution of the utility model is further described below by description of the drawings and specific embodiment.

Embodiment 1

As Figure 1-Figure 2, a kind of skirt bolt hole is away from verifying attachment, including hollow measurement pipe 1, fixing bolt 2, fastening Nail 5 and telescoping tube；The telescoping tube composition includes the hollow pipe box 3 at 4 two ends of steel tube core 4 and steel tube core, by steel pipe The flexible length of tube of relative slidable adjustment between core 4 and pipe box 3, described two pipe boxes 3 lead to respectively in telescoping tube shrinkage direction side Cross three fastening nails 5 to be fixed on steel tube core 4, the fastening nail 5 is located in same vertical plane, along pipe box 3 radially Even distribution.Two pipe boxes 3 are respectively equipped with fixing bolt 2 in telescoping tube direction of extension side, and fixing bolt 2 is set perpendicular to pipe box 3 Put, on fixing bolt 2, be cased with the interior hollow measurement pipe 1 for setting screw thread, hollow measurement pipe 1 passes through female thread and fixing bolt 2 connects. The steel tube core 4 and hollow measurement pipe 1 are detachable, select size patch according to actual skirt diameter, bolt hole internal diameter The tube core 4 and hollow measurement pipe 1 of conjunction.

In the present embodiment, fixing bolt 2 selects M10 bolts, diameter 10mm.2 centre-to-centre spacing pipe box outer edge water of fixing bolt Put down apart from 15mm.Fastening 5 centre distance pipe box inside edge 50mm of nail.

As Figure 3-Figure 4, which uses step as follows to the use state figure of this device：

（1）The length of adjustment telescoping tube, is positioned by 6 diameter length of tape measure skirt and with fixing bolt；

（2）The hollow measurement pipe of the minimum outer diameter allowed according to the size of 7 internal diameter of skirt bolt hole, supporting tolerance, and lead to The fixing bolt for crossing telescoping tube two ends tightens fixation.

Skirt bolt hole is set with using this device, if smoothly can be set with, shows that skirt bolt hole meets In-site installation is required.
