Description
Technical field
The present invention is mainly concerned with asphalt roads and builds apparatus field, refers in particular to a kind of contact type distance measuring apparatus of asphalt concrete conveyor.
Background technology
Asphalt concrete conveyor is the support equipment of bituminous concrete paver construction, intert between asphalt transport vehicle and paver, store, transport and mix and stir again asphalt from haulage truck, reach the demixing temperature and the aggregate segregation that improve asphalt, reduce the road surface voidage, realize the glitch-free continuous construction operation of paver, thereby improve the purpose of pavement spread quality and flatness.
It is relative constant to require transfer car(buggy) and distance between the paver to remain in whole construction course, avoids producing collision.Therefore present most transfer car(buggy) adopts apart from automatic following control system.These systems all adopt contactless range observation mode, wherein mostly with ultrasonic sensor (emission, receiving device) as the control signal source.Though adopt ultrasonic sensor can satisfy the request for utilization of loader transporter preferably, have following problem:
1, environment for use (as the flue gas of bituminous concrete, airborne dust, high temperature etc.) has a negative impact (as signal interference or decay, temperature drift) to the signal and the sensor of reflection, sometimes even cause dropout;
2, higher to installation, the request for utilization of reflection unit, in the work as the reflecting plate position skew (especially angle) slightly or distortion take place, cause probably causing sensor to can't accept signal (being dropout) because of the reflected signal skew; Perhaps, the reflecting surface of reflecting plate cause the serious decay of reflected signal that dropout takes place because of being stained with dust;
3, for satisfying above-mentioned requirements, that sensor must be taked to add is high-power, temperature compensation, measure such as high temperature resistant, causes price to increase considerably.So total system is with high costs, request for utilization is harsh, and reliability is not ideal enough.
Summary of the invention
The technical problem to be solved in the present invention just is: at the technical matters of prior art existence, the invention provides a kind of mode that adopts contact type distance measuring, and simple in structure, with low cost, use reliably, can be applicable to the contact type distance measuring apparatus of the asphalt concrete conveyor of different operating modes.
In order to solve the problems of the technologies described above, the solution that the present invention proposes is: a kind of contact type distance measuring apparatus of asphalt concrete conveyor, it is characterized in that: it comprises angular transducer, fork, weight, push rod and connecting rod, angular transducer and fork are fixed on the frame of transfer car(buggy), weight is fixed in the bottom of fork, and push rod links to each other with weight and forms certain angle with fork; Described connecting rod one end links to each other with angular transducer; The other end links to each other with fork.
Compared with prior art, advantage of the present invention just is: the contact type distance measuring apparatus of asphalt concrete conveyor of the present invention adopts the mode of contact type distance measuring, with the signal pickup assembly of continous way as the control signal source, as angular transducer, by swing-bar mechanism the rectilinear motion of variable in distance between transfer car(buggy) and the paver is converted into and rotatablely moves, and change it into electric signal as input signal and export to control system, thereby realize the purpose of command range; And that the present invention has is simple in structure, with low cost, use advantages such as reliable, can be applicable to different operating modes, highly versatile, and applicability is wide.

Embodiment
Below with reference to the drawings and specific embodiments the present invention is described in further details.
As depicted in figs. 1 and 2, the contact type distance measuring apparatus of asphalt concrete conveyor of the present invention comprises angular transducer 1, fork 5, weight 6 and push rod 7, angular transducer 1 is fixed on the frame 3 of transfer car(buggy), fork 5 links to each other with frame 3 by connecting pin 4, weight 6 is fixed in the bottom of fork 5, and push rod 7 links to each other with weight 6 and forms certain angle with fork 5; This fork 5 links to each other with connecting rod 2 by screw bolt and nut, and connecting rod 2 links to each other with angular transducer 1 through bolt, and fork 5 is adjustable with the phase place of connecting rod 2.The pushing tow of push rod 7 is positioned at the receiving hopper place on the paver.
Principle of work: when fork 5 is in free state following time, be in the reference position of fork 5, when push rod 7 is run into discharge bucket, fork 5 swings, and pass through screw bolt and nut drivening rod 2 and swing together, connecting rod 2 contacts with angular transducer 1 by bolt, and pendulum angle is converted to electric signal output, this electric signal sends the controller of complete machine to, sends right instructions according to the signal that collects to transfer car(buggy) by controller.Fork 5 plays the effect of automatically reseting under weight 6 effects.
Referring to shown in Figure 3, L is the maximal regulated scope of air line distance between transfer car(buggy) and the paver among the figure, φ A is its angular adjustment value, and wherein φ A can suitably regulate as required, by the quality of adjusting weight 6 and the adjusting that the angle between push rod 7 and the fork 5 can be finished φ A.When fork 5 is positioned at reference position E
0The time, the distance between paver and the transfer car(buggy) is a ultimate range at this moment, when paver was run into fork 5, transfer car(buggy) could begin to carry out mass transport; Reach the centre position E of fork 5 when fork 5
1The time, the distance between paver and the transfer car(buggy) is an optimum distance at this moment, paver and transfer car(buggy) also are in best operational position simultaneously; When fork 5 reaches sink node position E
2The time, system reports to the police by the signal value that provides, and must suitably improve transfer car(buggy) speed or paver this moment and shut down.
