Problems solved by technology
[0002] At present, the cutting cutterheads of the pipe jacking construction machines used in large-diameter tunnels are all made very large, and the torque generated when the cutterheads rotate and cut is also very large. If there is a hard soil layer or a large hard object , it will often cause the overall deflection of the pipe jacking machinery, increasing the construction difficulty or making the construction impossible

Embodiment Construction
[0012] Accompanying drawing is a kind of concrete embodiment of the present invention, and this embodiment comprises cylindrical shell 5, and bulkhead 2 separates mud tank 12 and working cabin 11, and annular sliding sleeve 3 is fixed on the shell, and inner The outer ring of the ring gear 6 slides on the sliding sleeve 3, the inner ring gear 6 meshes with the gear 7, and the right end of the gear 7 is provided with a reduction motor A8, and the inner ring gear 6 is connected to the circular peripheral cutter head through the cutter head support 4 13. The deceleration motor B is set in the middle of the jacking pipe, and the left end of the deceleration motor B is connected to the middle cutterhead 14 through the output shaft 9. There are three cutterhead holes 10 on the middle cutterhead, and several cutter teeth 1 are provided on both cutterheads. .
[0013] When the present invention works, the reduction motor B drives the middle cutterhead to rotate clockwise, the reductio...

The invention relates to a torque-balanced jacking pipe for pipe-jacking construction machinery, which comprises a cylindrical shell, a compartment partition plate partitions a cement compartment from a working compartment, an annular sliding bush is fixed on the shell, the outer circle of an inner gear ring can slide on the sliding bush, the inner gear ring is engaged with a gear, a gear motor A is arranged on the right end of the gear, and the inner gear ring is connected with annular peripheral cutterheads through cutterhead supports; a gear motor B is arranged in the middle of the jacking pipe, the left end of the gear motor B is connected with a middle cutterhead through an output shaft, the middle cutterhead is provided with three cutterhead holes, and the two cutterheads are respectively provided with a plurality of cutter teeth. The torque-balanced jacking pipe adopts the two cutterheads, the middle cutterhead is rotated clockwise, the peripheral cutterheads are rotated counterclockwise, the torque of the two cutterheads is balanced, and thereby the deflection of the jacking pipe equipment cannot be caused.
Description
1. Technical field [0001] The invention relates to a pipe jacking, in particular to a torque balanced pipe jacking of a pipe jacking construction machine. 2. Background technology: [0002] At present, the cutting cutterheads of the pipe jacking construction machines used in large-diameter tunnels are all made very large, and the torque generated when the cutterheads rotate and cut is also very large. If there is a hard soil layer or a large hard object , It will often cause the overall deflection of the pipe jacking machine, increase the difficulty of construction or make the construction impossible. 3. Contents of the invention: [0003] The present invention makes up for the shortcomings of the above pipe jacking equipment, and provides a torque balanced pipe jacking. [0004] The present invention is achieved through the following technical solutions: [0005] A torque balance jacking pipe, including a cylindrical shell, the bulkhead separates the mud tank from the w...
