The invention discloses an elliptical tunnel boring machine. A motor is arranged in the middle of the boring machine; the left end of the motor is fixed on a baffle plate; a third gear is arranged at the right end of the motor; the upper part of the third gear is meshed with a first gear; the lower part of the third gear is meshed with a second gear; the first gear is screwed on a first screw shaft through a middle internal thread sleeve; the second gear is screwed on a second screw shaft through the middle internal thread sleeve; the upper end of the first screw shaft is hinged with a second girder; the lower end of the second screw shaft is hinged with a third girder; the right end of the first girder is hinged with the upper end of a first tension arm; the left end of the first girder is hinged with the baffle plate at a certain distance from a first cutterhead; the right end of the second girder is hinged with the upper end of a second tension arm; the left end of the second girder is hinged with the baffle plate at a certain distance from a second cutterhead; the right end of the third girder is hinged with the lower end of the first tension arm; the left end of the third girder is hinged with the baffle plate at a certain distance from a third cutterhead; the right end of a fourth girder is hinged with the lower end of the second tension arm; the left end of the fourth girder is hinged with the baffle plate at a certain distance form a fourth cutterhead; the cross sections of the first cutterhead and the fourth cutterhead are of semicircular shapes; the cross sections of the second cutterhead and the third cutterhead are of rectangular shapes.

Description

Oval tunnel drilling and digging machine

Technical field

The present invention relates to the oval tunnel drilling and digging machine of a kind of tunnel drilling and digging machine, particularly a kind of tunnel construction machinery.

Background technology

At present, the tunnel drilling and digging machine all is to finish by driving a big cutterhead rotary cutting, can only form a circular tunnel during cutterhead rotary cutting.

Summary of the invention

The present invention has remedied the shortcoming of above tunnel drilling and digging machine, and a kind of oval tunnel drilling and digging machine is provided.

The present invention is achieved through the following technical solutions:

A kind of oval tunnel drilling and digging machine, motor is located in the middle of the drilling and digging machine, the motor left end is fixed in baffle plate, the motor right-hand member is provided with the 3rd gear, first gear is meshed on the 3rd gear top, second gear is meshed in the bottom, and first gear is threaded onto first helical axis by internal thread cover in the middle of it, and second gear is threaded onto second helical axis by internal thread cover in the middle of it; Hinged second beam in first helical axis upper end, hinged the 3rd beam in the second helical axis lower end; Hinged first arm of force of first beam right-hand member upper end, the first beam left end is with a certain distance from the hinged baffle plate of first cutterhead, hinged second arm of force of second beam right-hand member upper end, the second beam left end is with a certain distance from the hinged baffle plate of second cutterhead, hinged first arm of force lower end of the 3rd beam right-hand member, the 3rd beam left end is with a certain distance from the hinged baffle plate of the 3rd cutterhead, hinged second arm of force lower end of the 4th beam right-hand member, and the 4th beam left end is with a certain distance from the hinged baffle plate of four blade dish; The cross section of first cutterhead and four blade dish is semicircle, and the cross section of second cutterhead and the 3rd cutterhead is rectangle.

The present invention has following characteristics:

Every two adjacent cutterhead relative motions in the present invention's first cutterhead, second cutterhead, the 3rd cutterhead, the four blade dish can be with the boulder grating in the earth.

Description of drawings

The present invention is further illustrated below in conjunction with accompanying drawing:

Fig. 1 is structural representation of the present invention;

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

Among the figure: 1, first cutterhead, 2, first beam, 3, second cutterhead, 4, second beam, 5, the 3rd cutterhead, the 6, the 3rd beam, 7, the four blade dish, 8, the 4th beam, 9, first arm of force, 10, second arm of force, 11, first helical axis, 12, second helical axis, 13, first gear, 14, second gear, 15, motor, 16, baffle plate, 17, the 3rd gear, 18, shell, 19, cutter tooth.

The specific embodiment

Accompanying drawing is a kind of specific embodiment of the present invention, this embodiment motor 15 is located in the middle of the drilling and digging machine, the motor left end is fixed in baffle plate 16, the motor right-hand member is provided with the 3rd gear 17, first gear 13 is meshed on the 3rd gear top, the bottom is meshed second gear, 14, the first gears and is threaded onto first helical axis, 11, the second gears by internal thread cover in the middle of it and is threaded onto second helical axis 12 by internal thread cover in the middle of it; Hinged the 3rd beam 6 in first helical axis hinged second beam 4, the second helical axis lower ends, upper end; Hinged first arm of force of first beam, 2 right-hand members 9 upper ends, the first beam left end is with a certain distance from first cutterhead, 1 hinged baffle plate, hinged second arm of force of the second beam right-hand member 10 upper ends, the second beam left end is with a certain distance from second cutterhead, 3 hinged baffle plates, hinged first arm of force lower end of the 3rd beam right-hand member, the 3rd beam left end is with a certain distance from the 3rd cutterhead 5 hinged baffle plates, hinged second arm of force lower end of the 4th beam 8 right-hand members, and the 4th beam left end is with a certain distance from four blade dish 7 hinged baffle plates; The cross section of first cutterhead and four blade dish is semicircle, and the cross section of second cutterhead and the 3rd cutterhead is rectangle.

When the present invention works, commutator control motor-driven the 3rd gear is rotated in the forward a few, then reverse rotation a few, carry out repeatedly, pass through the forward of first gear and second gear thus, backward rotation, drive first helical axis and the right-hand member of the second helical axis reciprocating sliding, second beam and the right-hand member of the 3rd beam, the right-hand member of second beam is by the right-hand member of second arm of force push-and-pull the 4th beam, the right-hand member of the 3rd beam is by the right-hand member of first arm of force push-and-pull, first beam, so, first cutterhead, second cutterhead, the 3rd cutterhead, every two adjacent just relative motions of cutterhead in the four blade dish, cutter tooth bores at the volley and scrapes out the tunnel.
