Abstract
The utility model relates to a cutting transmission for small diameter mud-water balanced pipe heading machine, which comprises a motor, a reducer, a unit of transmission shaft, a knife rest, a knife tray, and a main mud cutting knife. An oil vat of the knife rest is arranged between the reducer and the unit of transmission shaft; and a display device with the same size of a mud cutting mouth is arranged on a plunger of the oil vat of the knife rest. Thereby, a long pull rod connected to the main mud cutting knife is driven by the oil vat of the knife rest to make the main mud cutting knife move backwards and forwards to make the size of the mud cutting mouth change with the movement of the main mud cutting knife. The operator on the ground can directly learn the position of the main mud cutting knife so that the size of the mud cutting mouth of the mud-water balanced pipe heading machine can be changed according to different geological conditions to control the quantity of mud fetching.
Description
The utility model relates to the equipment of non-excavation pipeline construction technology in a kind of urban construction, specifically belongs to a kind of cut transmission unit that is used for small-bore mire water equilibrium tube development machine.
In urban construction, adopt the method for non-excavation pipeline construction technology more and more at present, mainly adopt the mire water equilibrium tube development machine to construct.The pipeline of larger caliber adopts the non-coaxial output of power, with the pipe jacking tunnelling machine of the cut transmission unit of scalable knife rest; And small-bore pipeline is because the space is limited, the general pipe jacking tunnelling machine that adopts the cut transmission unit of the coaxial output of power, non-telescoping knife rest, the mud mouth cutting size of this kind pipe jacking tunnelling machine is fixed, can't change the amount of fetching earth size, therefore in the geological stratification of drift sand is arranged, can too much cause surface subsidence because of drift sand.
Problem at above-mentioned existence, the utility model proposes a kind of cut transmission unit of small-bore mire water equilibrium tube development machine, so that the mire water equilibrium tube development machine at work can be according to the difference of geological condition, change the size of mud mouth cutting, and then control the amount of fetching earth what, can keep the pressure balance of the cutting surface soil body effectively, control the sedimentation on ground preferably.
The purpose of this utility model can be achieved through the following technical solutions: a kind of cut transmission unit of small-bore mire water equilibrium tube development machine, cutting trowel by the motor that is coaxially set, retarder, transmission shaft group, knife rest, cutterhead and master forms, be connected by splined shaft between described motor and retarder, described master cuts trowel and is connected by the output shaft of knife rest with the transmission shaft group with cutterhead, and a long draw is characterized in by their inside: be connected a knife rest oil cylinder by spline respectively between retarder and transmission shaft group.
The utility model is owing to increase a knife rest oil cylinder before the retarder of pipe jacking tunnelling machine cut transmission unit, drive with main with the knife rest oil cylinder and to cut the long draw that trowel links to each other, realize mainly cutting moving forward and backward of trowel, make the openings of sizes of mud mouth cutting cut moving forward and backward and changing of trowel with main.And, mud mouth cutting size display unit has been installed in the oil cylinder piston stroke range of knife rest oil cylinder, can make the terrestrial operation personnel understand main position of cutting trowel on the ground intuitively, so that change the size of mire water equilibrium tube development machine mud mouth cutting according to different geological conditions, and then control the amount of fetching earth what, thereby can keep the pressure balance of the cutting surface soil body effectively, control the sedimentation on ground preferably.
Preferred embodiment below in conjunction with the cut transmission unit of accompanying drawing and the small-bore mire water equilibrium tube development machine of the utility model elaborates to the utility model:
Fig. 1 is the structural representation of small-bore mire water equilibrium tube tunneling machine cutting transmission unit;
Fig. 2 is the structural representation of Fig. 1 intermediate slide oil cylinder;
Fig. 3 is the structural representation of mud mouth cutting among Fig. 1.
Referring to Fig. 1-3, be the cut transmission unit of a kind of small-bore mire water equilibrium tube development machine of the utility model, cut trowel 7 by motor 1, retarder 2, transmission shaft group 4, knife rest 5, cutterhead 6 and master and form.Motor 1 is connected by splined shaft with 2 of retarders, and the master cuts trowel 7 and is connected by the output shaft of knife rest 5 with transmission shaft group 4 with cutterhead 6, and a long draw 10 is by their inside.Between retarder 2 and transmission shaft group 4, be connected a knife rest oil cylinder 3 by spline respectively.
Knife rest oil cylinder 3 comprises oil cylinder piston 12, and supports the sliding axle 13 that is connected by rolling bearing with this oil cylinder piston; The external part of sliding axle 13 form splined section with the female splined shaft scarf of retarder 2.Oil cylinder piston 12 connects as one by sliding axle 13 and long draw 10.
During work, by injecting hydraulic oil in two pouring orifices 14 of front and back, oil cylinder piston 12 moves forward and backward, and drives sliding axle 13 and moves with long draw 10.Simultaneously, sliding axle and long draw are driven by retarder 2 and rotate, and power is passed to knife rest 5 and the main trowel 7 of cutting make rotation and fore and aft motion.Like this, the oil mass of two pouring orifices 14 by knife rest oil cylinder 3 passes in and out controls moving forward and backward of oil cylinder piston 12, is driven knife rests 5 and is mainly cut trowel 7 and move by long draw 10.Main mud mouth cutting size of cutting between trowel 7 and the cutterhead 6 is to cut moving forward and backward of trowel 7 and change along with main.The main junction plane beveling of cutting between trowel and cutterhead (shown in Figure 3).
One mud mouth cutting size display unit 16 is being installed in the oil cylinder piston stroke range of knife rest oil cylinder on the oil cylinder piston 12 of knife rest oil cylinder 3, and this mud mouth cutting size display unit can change the straight-line displacement of oil cylinder piston 12 into angle displacement and show.The terrestrial operation personnel utilize mud mouth cutting size display unit 16, just can understand main position of cutting trowel on the ground intuitively, thereby change the size of mire water equilibrium tube development machine mud mouth cutting according to different geological conditions, and then the control amount of fetching earth, can keep the pressure balance of the cutting surface soil body effectively, control the sedimentation on ground preferably.
