Description
Technical field
The utility model relates to a kind of parts of model shielding machine, relates in particular to a kind of driving guides of model shielding machine.
Background technology
Adopting model shielding machine to carry out indoor model test is that the research shield machine is to the adaptability on stratum or a kind of important means of influence.Some shield structure models are that purpose is carried out test with simulation prototype part, the muddy water formula model shielding machine that make (1989) such as the former and husbands of half section model shielding machine, the chestnut of making as Japanese scholar Sen Lin (1984), the bivalve simple helix model shield structure that miniature shield machine device that Nomoto etc. (1999) make and Tongji University (2006) make etc., these model shielding machines are because size is little, advance distance is short, does not all adopt special guide piece.True shield machine has special guidance system in work progress, this system is made of laser total station, signal transmission and electric supply installation, laser pick-off target, shield machine master-control room, cylinder rod elongation measurement mechanism etc., and wherein the shield machine master-control room is the core of laser-guided systems.Obviously, the complex structure of true shield machine guidance system, the cost height, operation inconvenience is not suitable for indoor model test.Along with going deep into of research, developed larger sized model shielding machine in recent years, make shop experiment to simulate to the whole process of prototype shield machine.Effective guidance method is realized the real-time control of tunneling process because the increase of model shielding machine size must be adopted simple, thereby makes model shielding machine along set straight ahead.
The utility model content
The purpose of this utility model just provides a kind of driving guides of model shielding machine, and this device can make things convenient in real time to be observed the working direction of model shielding machine, for the adjustment of tunneling direction provides foundation; And it is simple in structure, easy to use.
The utility model is realized its goal of the invention, and the technical scheme that is adopted is: a kind of driving guides of model shielding machine, its composition is: fixed mirror on the model shielding machine body towards after catoptron, and the axis normal of mirror mirror and model shielding machine; Fixed laser source on the tunnel at model shielding machine tunneling direction rear, fixing blank on the tunnel between lasing light emitter and the catoptron has registration holes on the blank, and lasing light emitter is vertical with the reflective mirror minute surface with the line at registration holes center.
The course of work of the present utility model and principle of work are: when model shielding machine during along lasing light emitter and pilot hole center line connecting direction linear advancement, the laser beam that lasing light emitter penetrates is passed the pilot hole on its place ahead blank, be mapped on the catoptron, reflected light after the reflection overlaps and passes pilot hole with incident light, do not produce any luminous point on blank, need not the working direction of shield machine is adjusted this moment.In case the run-off the straight of shield machine body is installed in the inclination that equal angular also can take place for catoptron on the shield machine body thereupon.Because lasing light emitter and blank are fixed on the tunnel, this moment, incident light still incided on the catoptron along original rectilinear direction; But because the inclination of catoptron, catoptrical direction changes, to penetrate along the direction that with the catoptron vertical line is axis of symmetry and incident light symmetry, reflected light departs from original rectilinear direction and is mapped to a certain position on the blank, form a luminous point, the distance between this luminous point and perforate and depart from the direction of perforate has shown departing from of model shielding machine tunneling direction, the perforate of reflection light point off-center is far away more, and the angle that model shielding machine tilts is big more.The operator adjusts the working direction of shield machine in view of the above, makes it return to the rectilinear direction of former setting.
Compared with prior art, the beneficial effects of the utility model are:
Utilize the laser beam behind the shield machine and the reflex of shield machine body upper reflector, whether the decision model shield machine departs from and departure degree on working direction accurately and efficiently, provide foundation for the operator adjusts tunneling direction in real time, guarantee that tunneling direction advances along set rectilinear direction.Owing to can be set to long distance between between lasing light emitter and catoptron, when making shield machine generation minor shifts angle, can make luminous point on blank, produce bigger skew, can be clear, intuitively and easily (driving) direction of advancing of shield structure model is observed.Whole device only is made up of lasing light emitter, catoptron, blank, and it is simple in structure, easy to use.
The utility model is described in further detail below in conjunction with accompanying drawing and concrete embodiment.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 be the utility model embodiment when shield machine has a down dip, the incident of laser beam and reflection route synoptic diagram.
Embodiment
Embodiment
Fig. 1 illustrates, and a kind of embodiment of the present utility model is, a kind of driving guides of model shielding machine, its composition is: fixed mirror on the model shielding machine body towards after catoptron 1, and the axis normal of catoptron 1 minute surface and model shielding machine; In fixed laser source, the rear of model shielding machine tunneling 2, fixing blank 3 between lasing light emitter 2 and the catoptron 1 has registration holes 4 on the blank 3, and lasing light emitter 2 is vertical with reflective mirror 1 minute surface with the line at registration holes 4 centers.
In this example, catoptron 1 specifically is installed on the native storehouse dividing plate 5 of model shielding machine.Because the axis of model shielding machine is the axis of cutterhead 6 bearings, and native storehouse dividing plate 5 is perpendicular to cutterhead 6 bearings, can guarantee that like this catoptron 1 is perpendicular to the model shielding machine axis.
Fig. 2 is the incident and the reflection route synoptic diagram of the laser beam of the utility model embodiment when shield machine has a down dip.As can be seen from Figure 2, when catoptron 1 is L apart from the distance of blank 3, as the shield machine body axis downward-sloping the α angle, be equivalent to catoptron 1 and rotated counterclockwise the α angle, reflected light will move up on blank so, and establishing displacement is S, have relation of plane down so between each parameter:
Usually the inclined angle alpha of shield machine is a small quantity simultaneously, so have:
tan2α≈2α (2)
So, (1) formula becomes:
S＝2L·α (3)
This formula shows, adopts the utility model device, on blank 3 tilt quantity of shield machine amplified 2L doubly, can be clear, intuitively and easily the working direction of shield structure model is observed.Equally, shield machine up, the inclination trace of left and right and other direction, also be exaggerated 2L and embody on the blank 3 in the wings after doubly, thereby play the effect of real-time guiding, be convenient to the timely adjustment of model shielding machine working direction.
