Abstract

The utility model relates to an underground horizontal direction regulating punching machine which belongs to the technical field of engineering machinery. The utility model is composed of a machine seat, a regulating arm, a press plate, a supporting post, an alidade, and a machine head, wherein, a main cylinder body 2 and a rear cylinder body 9 form a threaded connection on the machine head, a piston rod and a nut seat form a threaded connection, and an air hole C is arranged on an impact shaft; the main cylinder body and the impact shaft form a clearance fit, and the impact shaft and the piston rod also form a clearance fit to form a front cavity a and a rear cavity b. The utility model which can ensure that a needed hole can be penetrated to a needed position under the situation without damaging the road surface and without hindering the traffic has the advantages of simple operation and high efficiency.

Description

Underground horizontal direction regulating punching machine

The utility model belongs to technical field of engineering machinery, relates to a kind of equipment of laying pipeline in underground level perforation.

At present, tubing below road, the general laying method that excavates the road surface that adopts, another kind are to adopt push-bench that effective jack or other people construction method are carried out poling, it is low that these two kinds of methods exist efficient, and the poling error is big or destroy the road surface and influence deficiencies such as the appearance of the city and traffic.

The purpose of this utility model provides a kind of city urban operating mechanism of both having protected, and can efficiently, accurately, easily required hole be got to the engineering mechanical device of desired location again.

The utility model principle is as follows:

Have one to survey bus adjustment support arm 2 in directed support 1 tail bottom, between pressing plate 3 and support 1, place extruding perforation head 4, head 4 and pressing plate 3 and support 1 matched in clearance, be fixed with two pillars 5 on the support 1, surveying bus sight alidade 6 is fixed on the pillar 5 by threeway 7, threeway 7 can move up and down, it is vertically rotating to survey bus sight alidade 6, so that head 4 directed uses, by adjusting support arm 2, make the directrix G of sight alidade 6 aim at mark post, then the direction walked of head 4 is exactly the horizontal guideline G direction of sight alidade 6.

Extruding punch head 4 is major parts of punching, on head 4, there is one to survey bus H, colliding of head is 11 fixing by being threaded with Master cylinder body 12, Master cylinder body 12 is threaded with rear-bank rotor housing 19 usefulness, air feed piston rod 14 is connected with nut seat 16 usefulness rectangular threads, air feed piston rod 14 is compressed by rubber seal ring 20 with rear-bank rotor housing 19 with nut seat 16 and is connected, and impact groove 13 has pore C.Master cylinder body 12 and impact groove 13, impact groove 13 is matched in clearance with the air feed piston rod, form ante-chamber a and back cavity b, when compressed air enters piston rod 14 by air feed sebific duct 21, compressed air enters ante-chamber a by the pore C of impact groove 13, just be full of ante-chamber a and back cavity b simultaneously, because this moment, the ante-chamber gas load was bigger than back cavity active force, impact groove 13 moves backward, when pore C on the impact groove 13 passed through air feed piston rod 14, ante-chamber a gas just was inflated, and impact groove 13 continues to move backward simultaneously, when entering pore C to the head end position of air feed piston rod 14, the air of ante-chamber a is discharged to discharge chamber d, and discharge chamber d communicates with head 4 outer tubes, so its pressure equates with atmospheric pressure, yet the gas pressure height of impact groove back cavity b moves forward impact groove 13.When head 4 moves forward,, repeat because of principle impact groove 13 as mentioned above moves backward.

The utility model advantage is: use this equipment.Can drop into a small amount of manpower, not destroy the road surface, not influence under the situation of road traffic, can punch desired location to required hole exactly, easy and simple to handle, the efficient height is the comparatively ideal equipment of perforation engineering construction under the road.
