Description
Technical field
The utility model relate to a kind of on the metallic conduit, do not stopping under the pipe interior medium transport condition, drawing the self-advancing type electrical tapping machine that connects lateral.
Background technology
At present, in urban water supply, air feed and petrochemical industry, use the pipeline pumped (conveying) medium, when needs are set up lateral, two kinds of construction methods are often arranged: the one, stop the conveying of trunk line interior media earlier, cut off a section in the trunk line then, tee pipe coupling is installed therein, drawing of branched pipe of enforcement connects, and the weak point of this method is: at first will stop the medium transport of trunk line, this bring very big inconvenience can for people's production, life; Next is that the construction working amount is big, operation inconvenience, and installation process complexity; The 2nd, do not stop the pipe interior medium transport, replace tee pipe coupling with pipe clamp, and flat gate valve is installed on pipe clamp, tapping machine is contained on the gate valve, utilize tapping machine perforate on trunk line, perforate finishes, and withdraws from cutter, valve-off, pull down tapping machine, lateral is installed again, and thing finishes, and opens valve and gets final product.Take the tapping machine of second kind of construction method, normally used is grinding jacking heavy caliber tapping machine, owing to adopt diamond engineering thin-walled drill tools, be not suitable for processing to the ferrous metal pipeline, feed mostly is hand feed, not only the amount of feeding is inhomogeneous, and labour intensity is big and make cutter be easy to damage.
Summary of the invention
The purpose of this utility model is to provide a kind of self-advancing type electrical tapping machine that connects lateral, realizes auto-feed that draws under the situation that does not stop the pipe interior medium transport.
The purpose of this utility model can reach by following technical measures, that is: this self-advancing type electrical tapping machine, comprise casing, motor, gear, cutterhead, centre drill and handle, its key is: a pair of worm-drive pair is housed in casing, worm screw one end of its worm-drive pair is connected with driven gear is coaxial, the driving gear engagement on this gear and the motor output shaft; The worm gear of worm-drive pair is contained on the main shaft that stretches in the casing, also is coaxially installed with a nut gear and a gear in the worm gear both sides; Nut gear and described gear are meshed with duplicate gear respectively; The external part of main shaft is equipped with body, centre drill and cutterhead successively; Bevel-gear sett also is housed in casing, and one of them bevel gear is connected by the outer body of screw rod and casing, and described duplicate gear is connected with the outer operating grip of casing.
Be set with collar bush on the main shaft of the utility model outside being positioned at casing, described body is sleeved on the collar bush of main shaft.Because main shaft is contained in the collar bush, has not only increased the rigidity of main shaft, and has shortened the total length of main frame.
Adopt the advantage of such scheme to be: length is short, good rigidly, and labour intensity is little, and the depth of cut is even, is difficult for knife.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the right view of Fig. 1.
Fig. 3 is the annexation figure of bevel gear by screw rod 12 and body 11.
The specific embodiment
Below with reference to accompanying drawing concrete structure of the present utility model and working condition are further described:
Referring to Fig. 1, Fig. 2, a kind of self-advancing type electrical tapping machine of the utility model, form by driven gear 1, driving gear 2, motor 3, casing 4, worm screw 5, worm gear 6, gear 7, nut gear 8, cutterhead 9, centre drill 10, body 11, screw rod 12, bevel gear 13, duplicate gear 14, main shaft 15 and handle 16, wherein, a pair of worm-drive pair is housed in casing 4, worm screw 5 one ends of its worm-drive pair and 1 coaxial connection of driven gear, driving gear 2 engagements on this gear 1 and motor 3 output shafts; The worm gear 6 of worm-drive pair is contained on the main shaft 15 that stretches in the casing 4, also is coaxially installed with a nut gear 8 and a gear 7 in worm gear 6 both sides; Nut gear 8 and described gear 7 are meshed with duplicate gear 14 respectively; The external part of main shaft 15 is equipped with body 11, centre drill 10 and cutterhead 9 successively; Bevel-gear sett 13 also is housed in casing 4, and one of them bevel gear is connected with casing 4 body 11 outward by screw rod 12; Described duplicate gear 14 is connected with casing 4 outer operating grips 16.Be set with collar bush 17 on the main shaft 15 outside being positioned at casing 4, described body 11 is sleeved on the collar bush 17 of main shaft 15, has shortened exchange length like this, has strengthened rigidity.
Described nut gear 8 is connected with spindle thread; Described gear 7 is connected with main shaft key.According to the above-mentioned self-advancing type electrical tapping machine that assembles, during work, the flat gate valve that will have pipe clamp earlier is contained on the trunk line that need set up lateral, and then this machine of loading onto, open valve, connect power supply, the motor rotation, and by gear 2, the gear 1 that is meshed, with gear 1 coaxial worm 5, order about worm gear 6 rotations that are meshed with worm screw 5, thereby drive main axis rotation, produce cutting movement;
Simultaneously with worm gear 6 coaxial mounted gear 7 rotations, order about duplicate gear 14 rotations that are meshed, because duplicate gear 14 is under the control of operating grip 16, the energy move left and right is when duplicate gear 14 past moving right, with nut gear 8 engagements, can realize the fast advance and retreat of main shaft, during past moving left,, can realize the auto-feed of main shaft with gear 7 engagements.When the hole completion of processing, withdraw from cutter, valve-off is pulled down this machine, and lateral is installed, and opens valve, end-of-job.In the present embodiment, keyway on the main shaft and screw thread dual structure form in an overlapping; The straight end-face key that is connected to of centre drill and cutterhead, main shaft is connected; Rotate the bevel gear on the casing in addition, can drive the screw rod rotation, realize the move left and right of body and casing.The utility model compared with prior art, when having solved perforate in the past, deficiencies such as hand feed labour intensity is big, the depth of cut is inhomogeneous, easy knife can be widely used in and not stop the pipe interior medium transport on trunk line, draw and connect lateral.
