Background technology
In prior art, it is relevant with the utility model to find U.S. Pat 870064, and it is a kind of operate as normal that does not stop pipeline under system pressure, holes, tapping to be to install the equipment of lateral.But when this boring, tapping machine are 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 poor, 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 large diameter pipeline.In addition ZL98228352.1 disclose a kind of on large diameter pipeline perforate so that the electrical tapping machine of lateral to be installed, this machine comprises motor, decelerator, transmission case and fenestration product, motor connects with decelerator, decelerator connects with transmission case respectively with fenestration product, four big parts combine as a whole, during construction operation, need disposable integral to be installed on the gate valve of band pipe clamp, seem very heavy; Secondly, because connecting between the drive sleeve of ordering about main axis rotation and main shaft is splined, its underpart is by the sealing of O RunddichtringO, and its sealing effectiveness is poor.
Summary of the invention
It is a kind of on the pipeline of carrying liquid, gas that the purpose of this utility model is to provide, and do not stop medium transport and perforate thereon so that light, electrical tapping machine efficiently is installed when lateral, construction operation are installed.
The purpose of this utility model can reach by following technical measures: promptly this electrical tapping machine, comprise motor, gear-box and fenestration product, its key is: the quick mounting mechanism of motor, the sealing mechanism that can make main shaft and drive sleeve keep the excellent sealing state.
The quick mounting mechanism of described motor, comprise the motor base (frame) that combines as a whole with motor, motor base (frame) is provided with a groove, this groove can be stuck on the screw rod that combines as a whole with pressing plate, screw rod passes motor bracket, its head connects with locking nut, when needs are locked at motor on the motor bracket, only need and to be stuck in the motor base (frame) that motor combines as a whole on the screw rod, turn locking nut handle can be locked at motor on the motor bracket firmly, make it to link by shaft coupling again, carry out bore operation thereby form a complete electrical tapping machine quickly with gear-box; In like manner, motor is separated with gear-box, electrical tapping machine is broken the whole up into parts, easily transfer to new operation place.
For motor base (frame) and motor bracket are more fast located exactly, can establish a boss or a groove that mates mutually at motor base and motor bracket connection part.
It can be boss and straight trough that described motor base and motor bracket connection part are established a boss or a groove that mates mutually, or dovetail and dovetail groove, or T-shape key and T-shape groove.
Described tie down screw from left to right is followed successively by plate-like, flat axle shape, screw shaped.
A described sealing mechanism that can make main shaft and drive sleeve keep the excellent sealing state comprises main shaft and drive sleeve, and its key is in the termination of two coupling components, is provided with the sealing ring that shape that main shaft and drive sleeve point of attachment constituted is complementary.
The sealing ring that the shape that described main shaft and drive sleeve point of attachment are constituted is complementary refers to: when main shaft and drive sleeve were respectively flat axle and flat axle sleeve, then sealing ring was shaped as that cylindrical is interior to be the shape of flat axis hole; When main shaft and drive sleeve were key connecting, then sealing ring was shaped as the shape that key is arranged in the cylindrical.
According to the above-mentioned electrical tapping machine that assembles, saved traditional electrical tapping machine except gear-box is arranged, a decelerator that also is provided with had both reduced cost, had alleviated weight again; The second, traditional electrical tapping machine, its motor is located at the fenestration product middle and upper part, because position height, cause poor stability, vibrations are big, both damaged cutter easily, influenced the life-span, also be unfavorable for guaranteeing the perforate precision, and motor of the present utility model is contained on the gear-box, and is positioned at the fenestration product bottom, its good stability, perforate precision height, and can effectively prolong service life of tapping machine; The 3rd, these machine mounting or dismounting are simple, the transfer tasks place is convenient; The 4th, owing to be provided with the sealing ring that shape that main shaft and drive sleeve point of attachment constituted is complementary, its good sealing effect.
