Description

Arched tunnel excavator

Technical field

The utility model relates to the arched tunnel excavator of a kind of tunnel excavator, particularly a kind of tunnel construction machinery.

Background technology

At present, tunnel excavator all, by driving a cutterhead rotary cutting to complete, can only form a circular tunnel during cutterhead rotary cutting.

Summary of the invention

The utility model has made up the shortcoming of above tunnel excavator, and a kind of arched tunnel excavator is provided.

The utility model is achieved by the following technical solution:

An arched tunnel excavator, motor left end is provided with driving gear, driving gear engagement driven gear, driving gear left end is connected with an axle, driven gear left end is connected with two axles, and an axle left end is connected with one and turns axle, and two axle left ends are connected with two and turn axle, one turns axle connects an arm right-hand member by a lever pin, two turn axle connects two arm right-hand members by two lever pins, the left end pin arcading body top of an arm, and the intermediate pin of an arm connects breast boards, the left end pin of two arms connects cuboid bottom, and two arm intermediate pins connect breast boards; One arm is arranged side by side two, and left end is by two key seat pin arcading bodies, and right-hand member connects as one, and the shape of the shape of two arms and an arm is equal to.

The utlity model has following feature:

The utility model can excavate arched tunnel.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, the utility model is further described:

Fig. 1 is structural representation of the present utility model;

Fig. 2 is that A-A of Fig. 1 is to view;

Fig. 3 is B-B sectional view of Fig. 1;

In figure: 1, support 2, motor, 3, driving gear, 4, driven gear, 5, bearing support, 6, an axle, 7, two axles, 8, one turns axle, and 9, two turn axle, 10, a bar, 11, two bars, 12, three bars, 13, four bars, 14, an arm, 15, two arms, 16, three arms, 17, four arms, 18, breast boards, 19, one key seat, 20, two key seats, 21, three key seats, 22, four key seats, 23, ogive, 24, cuboid, 25, cutter head.

The specific embodiment

Accompanying drawing is a kind of specific embodiment of the present utility model, these embodiment motor 2 left ends are provided with driving gear 3, driving gear engagement driven gear 4, driving gear left end is connected with an axle 6, driven gear left end is connected with two axles 7, one axle left end is connected with one and turns axle 8, two axle left ends are connected with two and turn axle 9, one turns axle connects arm 14 right-hand members by bar 10 pins, two turn axle connects two arm 15 right-hand members by two bar 11 pins, left end pin arcading body 23 tops of an arm, and the intermediate pin of an arm connects breast boards 18, the left end pin of two arms connects cuboid 24 bottoms, and two arm intermediate pins connect gear soil; One arm is arranged side by side two, and left end is by two key seat pin arcading bodies, and right-hand member connects as one, and the shape of the shape of two arms and an arm is equal to.

Four bar 13 lower end pins connect two arms, and four bar upper end pins connect four arm 17 right-hand members, and four arm left end pins connect cuboid top, and four arm intermediate pins connect breast boards; Three bar 12 upper end pins connect two arms, and three bar lower end pins connect three arm right-hand members, three arm left end pin arcading body bottoms, and three arm intermediate pins connect breast boards.

One axle is fixed on top by two bearing supports to be supported, and two axles are fixed on following support by following two bearing supports.

Driving wheel and driven pulley are all the same two gears of size and shape; The shape of cross section of ogive is arch, and the shape of cross section of cuboid is rectangle.

During the utility model work, motor drives driving wheel to drive driven pulley rotation simultaneously, by an axle, drive one to turn axle forward thus, by two axles drivings two, turning axle reverses, two turn axle distinguishes the right-hand member of push-and-pull one arm and two arms in rotation process, the just relative motion of ogive and cuboid, the cutter head on ogive and cuboid just excavates the tunnel that overarches.
