Abstract
The utility model relates to a hole making machine for cement and cast iron pipes. The utility model makes holes and mills holes on the liquid convey pipeline, which is convenient for mounting the branch pipeline. The utility model comprises an electric motor and a shaft coupling. The utility model is composed of an axial feed mechanism, a power transmission mechanism, and a material fastening and trepanning drilling and milling mechanism. The utility model is integrated with a pipeline made with holes through pipe clips and screw bolts. The operation is stable. The hole making precision is high. As the cutting tool is made of hard alloy, the utility model is used for making holes for cement and cast iron pipes, and the utility model overcomes the shortages that traditional mechanical function is single and the application range is narrow.
Description
The utility model relate to a kind of carry on the pipeline of liquid bore, hole milling is so that install the device of lateral, particularly relates to a kind of cement, cast iron pipe tapping machine.
In prior art, U.S. Pat 3870064 is the operate as normal that do not stop pipeline under pressure, carries out drilling and tapping to connect lateral.When this tapping machine is fixed on the pipeline, only depend on a chain, thereby when work is very unstable, be difficult to guarantee borehole accuracy, and,, can only be used for common water supply industry because sealing effectiveness is bad, conveyance conduit to other liquid such as oil, chemical industry but is willing and yet unable to help, and is powerless especially to the perforate of the perforate of large diameter pipeline and concrete duct.
The purpose of this utility model is to provide a kind of and does not stop its operate as normal on the pipeline of carrying liquid, carries out perforate so that cement, the cast-iron pipe tapping machine of lateral to be installed.
The purpose of this utility model can realize by following technical measures.That is: adorn the pipe clamp of a strap brake valve on by the pipeline of perforate, in a side of last pipe clamp, adorn a ball valve that is connected with blow-off pipe, cement, cast-iron pipe tapping machine then are contained in pipe clamp top, and by the bolt Joint.An axial feed mechanism, a Poewr transmission mechanism and solid, compound drill milling mechanism of jacking of being characterised in that of the present utility model.
Described axial feed mechanism is by worm gear, worm transmission pair, and with the joining handwheel of worm screw, and worm gear links and the upper end is stuck between two plane bearings, bottom and the joining nut of screw mandrel are formed;
Described Poewr transmission mechanism is by motor, shaft coupling/flexible axle, and the worm and gear transmission, and form with worm gear and the joining drive sleeve of main shaft respectively;
Described solid, the compound brill of jacking, milling mechanism is inserted in the spindle hole by the hollow fraise that is contained in spindle nose, an end and bored by the solid material that pull-rod nut is reinforced and to form, and is provided with an elastic telescopic pin admittedly expect bit head.
Accompanying drawing is a general structure schematic diagram of the present utility model.
Below with reference to accompanying drawing concrete structure of the present utility model and working condition are further described.
Referring to accompanying drawing, at first on by the pipeline of perforate, adorn a upper and lower pipe clamp 19,18, side at last pipe clamp has a gate valve 17, and opposite side is equipped with a ball valve 10 that is connected with blow-off pipe 20, then the utility model cement, cast-iron pipe tapping machine is contained in pipe clamp 19 tops.This machine is characterised in that: an axial feed mechanism, a Poewr transmission mechanism and solid, the compound drill milling mechanism of jacking.Axial feed mechanism is by worm and gear transmission 4,12, and with worm screw 12 joining handwheels 13, and worm gear 4 links and the upper end is stuck between two plane bearings 2, bottom and screw mandrel 5 joining nuts 3 are formed.During work, only need shake handwheel 13, make worm screw 12 drive worm gears 4 and during with joining nut 3 rotations of worm gear, nut 3 just can be along the back-out that is threaded into of screw mandrel 5, thereby drives about the joining main shaft, realizes axial feed.Poewr transmission mechanism is by motor 15, shaft coupling 14, worm and gear transmission 7 and form with worm gear and main shaft 8 joining drive sleeve 6 respectively.As long as one connects power supply, the motor rotation drives worm screw, worm gear and then drive shaft rotation by shaft coupling/flexible axle, cuts.Gu, the compound drill milling mechanism of cover is inserted in the spindle hole by the hollow fraise 21, the end that are contained in main shaft 8 ends and bore 9 by the solid material that pull-rod nut 1 is reinforced and forms, is provided with an elastic telescopic pin 11 at the head of solid material brill 9.When connecting power supply, main axis rotation is shaken handwheel 13, makes can order about main shaft and move down and cut, and the size of the amount of feeding easily rotates to be suitable with handwheel.Hole drill, mill logical after, blow-off pipe 20 promptly has liquid to flow out, and adjust the open amount of ball valve 10 this moment, and the bits that discharge capacity reduced to brill can be milled are not discharged from blow-off pipe 20 and are advisable, being located at the elastic telescopic pin 11 that solid material bores 9 heads simultaneously radially ejects, support is lived the piece material that cover cuts off, and cuts off the electricity supply, then, slowly shake handwheel 13, make and move to initial position on the main shaft, clockwise rotate handwheel again, gate valve 17 is closed, this moment, blow-off pipe 20 answered no liquid to flow out, unload ball valve 10, load onto plug, take off cement, cast-iron pipe tapping machine and gusset piece, load onto lateral, the breakdown gate valve 17 then, and lateral gets final product normal operation input, and operation is finished.
The utility model compared with prior art because this tapping machine is fastened on by the Pipe Cutting road by upper, lower tube, it connects reliable, working stability, perforate precision height; Owing to adopted the mode of jacking perforate, greatly reduced cutting output, be conducive to improve the service life of cutter and machine, be conducive to increase work efficiency; Since bore, mill the bits that get off cannot not by in the pipeline with the liquid of pressure with outside its discharge pipe, prevented the pollution of institute's transfusion fluid; Because brill, milling cutter are made by carbide alloy, have not only prolonged cutter life, and can be to the pipeline tapping of cement, cast iron quality, widened the scope of application, in addition, this machine is specially adapted to straight through being on the pipeline of 100-1200 millimeter, opens the hole that straight warp is the 50-200 millimeter.
