Abstract
The utility model provides an elbow detaching and mounting device suitable for pipeline rapid repair and suitable for mounting various apron interfaces additionally equipped with lathedogs. The elbow detaching and mounting device comprises a screw rod and nuts, and is characterized in that the screw rod is inserted into a bolt hole of an anti-shedding lathedog; the two nuts are screwed into the two ends of the screw rod; and the distance between the nuts is regulated through rotating the nuts, so that the aim of mounting or detaching an elbow interface is achieved. The device provided by the utility model has the advantages of simple structure and light weight, is easy to process, moves flexibly, is light and convenient to operate by being combined with the anti-shedding lathedog for use, and is particularly suitable for pipeline head hooking operation and projects needing to pass through crossed obstacles and have narrow working surfaces.
Description
Technical field
The utility model relates to a kind of attaching/detaching apparatus of flexible cushion rubber interface elbow, and this device is applicable to that pipeline installs the installation of the various cushion rubber interfaces of clip additional when rushing to repair fast.
Background technology
At present, the most of pipeline that adopts spheroidal graphite cast-iron tubing, particularly caliber less than 800mm of feedwater piping.The spheroidal graphite cast-iron pipeline need adopt flexible cushion rubber bell socket, it have the intensity height, corrosion-resistant, shock resistance good and the advantage of easy construction, but the installation of elbow difficulty, the elbow of caliber 400 above wide-angles especially.Elbow is installed and is mainly used bottle gouard moved by hands to draw in the past, because bend pipe tools length is less, difficult fixing, direction is difficult to maintenance when drawing in, and easily causes direction of pull and conduit axis inconsistent, causes cushion rubber frictional force to strengthen.And bottle gouard moved by hands pulling force control is difficult for the phenomenon that balance is easy to draw inclined to one side bursting cushion rubber, causes to do over again or leak.
The anticreep clip is installed at the channel bend place becomes a kind of trend just gradually.When adopting the anticreep clip, when having water leakage, it is convenient easily to find and rush to repair, and only need tighten the nut at harness cord two ends.The anticreep clip is not only applicable to adopt the construction area of conventional way, also is applicable to the situation that seepage need be rushed to repair that takes place that adopts.Use the anticreep clip to need not concrete perfusion, shorten the repairing time greatly.This device has good application prospects in outdoor water supply pipe road construction from now on.
Summary of the invention
When the utility model was primarily aimed at spheroidal graphite cast-iron generation leakage loss and needs repairing fast, the difficulty of flexible cushion rubber bell socket elbow installing/dismounting operation provided a kind of anticreep clip that cooperates to use and device simple in structure, convenient and quick construction.
The technical solution of the utility model is: this device is made up of screw rod and nut.It is characterized in that screw rod inserts in the keyhole of anticreep clip,, regulate the length of two nut middle screw rod by the rotation nut, thereby reach the purpose of installation or removal elbow interface two nut precession screw rod two ends.Aid when this device uses mainly is a spanner, and it is to use opening, plum blossom and a unidirectional spanner that slides that interface is installed; Use open-end wrench more convenient during the dismounting interface.
For guaranteeing that screw rod and nut can be repeatedly used, and screw rod and nut are designed to trapezoidal thread, and nut length are 50mm.At different anticreep clip keyhole diameters, the screw diameter different (seeing the following form) that different tube diameters uses.
| Caliber (mm) | Screw diameter (mm) | Spiro rod length (mm) | Nut length (mm) |
| 300 | 18 | 350 | 50 |
| 400 | 20 | 350 | 50 |
| 600 | 22 | 350 | 50 |
| 800 | 22 | 350 | 50 |
Device described in the utility model have simple in structurely be easy to processing, weight is little moves flexibly, uses operation light in conjunction with the anticreep clip, be particularly useful for the work of pipeline eave tile and pass through intersecting barrier, engineering that working face is narrow.Use this device pulling force to control easily and be difficult for sideslip, save the set-up time, significantly raising is mounted to power, and the advantage in the eave tile operation of cutting off the water is particularly evident.

The specific embodiment
Screw rod and nut all use the 45# steel to make in this device.When the anticreep clip was installed, flat mouthful of clip inward flange was apart from the socket 120mm that breaks end, and after the anticreep clip installed, three screw rods inserted in the keyhole of clips, and the screw rod two ends fix (see figure 6) uniformly with two nuts, and cushion rubber is stressed even when guaranteeing to draw in.Need use four screw rods when utilizing this device dismounting interface, every screw rod cooperates two nuts to use (see figure 8).Nut is installed in the middle of the two anticreep clips, and the rotation nut strengthens the distance of two nuts, thereby reaches the purpose of separation interface.
Claims (4)
1. one kind is applicable to the pipeline elbow attaching/detaching apparatus of repairing fast, form by screw rod and nut, it is characterized in that: during use screw rod is inserted in the keyhole of anticreep clip, two nut precession screw rod two ends, regulate the length of two nut middle screw rod by the rotation nut, thereby reach the purpose of installation or removal elbow interface.
