Embodiment Construction

[0028] Such as Figure 1-8 As shown, 1 is the main shaft, 2 is the flange connecting box, 3 is the connecting screw, 4 is the first feed screw, 5 is the second feed screw, 6 is the hand wheel, 7 is the end cap, 8 , 9 are the first thrust bearing and the second thrust bearing.

[0029] Such as Figure 1-8 As shown, the main shaft 1 is provided with a tool mounting thread 11 at one end, and a protruding ring 12 is provided at the other end, and a first thrust bearing 8 and a second thrust bearing 9 in opposite directions are respectively provided on both sides of the protruding ring 12 . The first thrust bearing 8 and the second thrust bearing 9 are covered with a handwheel 6 that matches with it, and the end cap 7 seals the first thrust bearing 8 and the second thrust bearing 9 in the handwheel 6, and the main shaft 1 and the handwheel 6 pass through Fasteners such as screws are fixedly connected together, so that when the handwheel 6 is turned, the main shaft 1 rotates accor...

Abstract

The invention discloses a two-stage sheathing tapping machine, comprising a main shaft, a flange plate connection box, a connection screw rod, a first feeding screw rod, a second feeding screw rod, a hand wheel, an end cap, thrust bearings and a cutter mounting thread. With the adoption of the two-stage sheathing tapping machine provided by the invention, a machine body is shortened; in such a way, the bearing load of a header pipe is lightened greatly, the stability of the header pipe in operation is increased, the construction error is decreased, the operation at heights and the construction in a narrow space are facilitated, and the transportation is facilitated as well; and therefore, the two-stage sheathing tapping machine is very applicable for actual construction. On the basis, the invention provides a tapping method based on the two-stage sheathing tapping machine; and the tapping method involves steps of tapping position selection and construction, and has a good construction effect.

Description

technical field [0001] The invention relates to a drilling machine and a drilling method, in particular to a two-stage sleeve drilling machine and a pipeline drilling method. Background technique [0002] Our company's original manual drilling machine has a fuselage length of 1400mm and a stroke of 430mm, but our company found in many actual constructions that the original drilling machine is difficult to meet the actual needs of high-altitude operations and construction in small spaces; at the same time, due to The length of the fuselage is 1400mm. During actual operation, the fuselage will inevitably shake and sway, which will also have a certain impact on the load-bearing of the main pipe and the stability of the main pipe; and because the fuselage of this drilling machine The length is also not conducive to carrying. [0003] To this end, the company carried out corresponding equipment research work. The survey results show that the minimum body length of the manual ho...
