Description

Supervisory-controlled robot
Technical field
The present invention relates to supervisory-controlled robot fields, and in particular to the removable supervisory-controlled robot in a kind of highway guardrail.
Background technique
As China's highway total kilometrage is continuously increased, national car ownership also cumulative year after year guarantees highway At a high speed, safety, economically the difficulty of operation management is also increasing, on a highway dispose monitoring system at highway One important means of modern management, supervisory-controlled robot are undoubtedly wherein important component part.
The supervisory-controlled robot on highway is generally fixedly mounted on higher column or cross bar at present, is all every one Section distance places one or several cameras, is fitted without robot then in highway guardrail to execute the prison to vehicle travel process Control, if exceeded the speed limit or traffic accident in the region that the region of not camera or camera distance do not see Chu farther out, The case where can not playing back at that time, increases difficulty to subsequent investigation.
In addition, the distance between the camera installed on highway at present and camera cannot automatically adjust, people is needed Work de-regulation, in some special cases, when such as encountering special red-letter day or having major event or activity, accident-prone road section is always Changing, at this moment corresponding monitoring point just should real-time perfoming adjustment, the accident temporarily generated easily send out section monitor should be more It is dense, certain usually Frequent Accidents and temporarily the section no longer easily sent out then can suitably reduce monitoring density, be more advantageous in this way Resource maximumlly utilizes.
In the prior art, there is also can move in the fields such as household supervisory-controlled robot and some special occasions such as substation inspection Dynamic supervisory-controlled robot, but be limited to small-scale application or need to have special application conditions, and in use, need A large amount of manual intervention is carried out, is not suitable for applying on a highway.
Therefore, there are no one kind to be suitable on highway in the prior art, transportable supervisory-controlled robot.
Summary of the invention
The main purpose of the present invention is to provide the removable supervisory-controlled robots on a kind of freeway guardrail, existing to solve Have the supervisory-controlled robot applied on technology high speed highway cannot shift position as needed the problem of.
To achieve the above objectives, the technical solution adopted by the present invention are as follows: the removable monitoring machine on freeway guardrail People, main body are divided into monitoring module and power plant module, and wherein monitoring module is by guardrail, track, position-limit mechanism, hollow housing, camera shooting Head mounting rack, camera composition, guardrail are integrally in C word groove type, and circular hollow shell, hollow housing and shield are arranged inside guardrail There are gap between column, effect is to prevent from generating friction inside hollow housing and guardrail, is provided with three groups outside hollow housing Position-limit mechanism, three groups of position-limit mechanisms are respectively embedded into the track inside guardrail, the position-limit mechanism insertions of three different directions to So that hollow housing circumferencial direction, which is restricted, to be rotated;Power plant module is by threaded rod, screw thread, position-limit mechanism, first motor Composition, screw thread setting install first motor, first motor connection screw thread bar, first motor in guardrail inner wall, hollow housing one end Threaded rod is driven to drive entire supervisory-controlled robot to move along the screw thread rotation of guardrail inner wall, position-limit mechanism can be moved along track It is dynamic, so that the camera of supervisory-controlled robot is also able to maintain stabilization in moving process, it will not influence quality monitoring.
As an improvement, supervisory-controlled robot further includes power supply module, to guarantee that camera can continue working, while confession is set Electric module can further increase the flexibility ratio and mobility of supervisory-controlled robot, power supply module is by power supply box, driving to avoid wiring Device, mobile plug, circuit travel switch, power supply connector, locator composition, power supply box are arranged in guardrail, and socket direction is moved The direction of dynamic plug, driving device, mobile plug, circuit travel switch, power supply connector, locator are arranged in hollow housing Portion, mobile plug can move along a straight line in a certain range, and tail portion one end of mobile plug is arranged in circuit travel switch, with For plug on same linear position, when mobile plug is in the position of connection power supply box, circuit travel switch connects with power supply Head connection, when electricity shortage, notice locator finds nearest power supply box, after locator has good positioning the position of power supply box, Driving device drives mobile plug mobile to power supply box, meanwhile, rack gear plug underlying circuit travel switch touches camera For plug, power supply box can charge to camera therewith.
Preferably, driving device is the second motor-driven gear, mobile plug is rack gear plug, the second motor driven Gear rotation band carry-over bar plug, but driving device is also possible to linear motor, tube shaped electric machine etc., as long as being able to achieve driving movement The purpose that plug moves linearly.
As an improvement, also adding lens in monitoring module, lens are mounted in hollow housing, and lens can be along hollow housing Hollow structure inside sliding, lens are retractable, effect be for overhauling, antitheft, waterproof and dustproof, anti-corrosion, Internal camera head can Monitor the image in lens visual range.
Preferably, the position-limit mechanism in monitoring module is driven tire, position-limit mechanism can be improved using driven tire With the contact condition of interorbital, also supervisory-controlled robot can be made more smooth when moving.
As an improvement, one end that hollow housing is used to install first motor thickeies, so that first motor is installed and improves it Installation strength.
This invention provides the technical solution of complete set, solves the monitoring applied on highway in the prior art Robot cannot shift position as needed the problem of, whole region can not be covered by not only solving fixing camera, camera shooting effect It the problem of the case where being exceeded the speed limit or traffic accident, can not being played back at that time in the bad region of fruit, also solves camera and takes the photograph As the distance between head cannot automatically adjust, artificial de-regulation is needed to monitor position and density especially in certain special red-letter days The problem of can not being adjusted as needed, also solves powerup issue of camera during automatic monitoring, achieves bright Aobvious technical effect has substantive distinguishing features outstanding and significant progress compared with prior art.
