Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is to be mounted on a self-propelled vehicle to perform multipurpose cleaning of a road structure with one vehicle, and to provide a road structure cleaning machine equipped with a guidance and tracking system for a target structure. It is provided.

[0002]

[Prior art]

 Conventionally used road structure cleaning vehicles have only one type of target structure, and the position control of the structure and the cleaning tool is mostly based on the operator's sensation, which depends on the skill of the operator. It is large and increases the operator's fatigue level, which is unfavorable from the social background of the recent lack of skilled labor.

[0003]

[Problems to be solved by the device]

 The conventional techniques described above have the following problems. Among the machines for cleaning road structures, conventional cleaning machines target only one type of structure. In other words, cylindrical and flat type cleaning machines cannot be cleaned by one cleaning machine. Further, the position control of the structure and the cleaning tool is a manual operation, and is based on the sense of the operator, and in many cases depends on the skill of the operator.

The present application has been made in view of such problems of the conventional technology, and an object of the present application is to provide a device capable of solving the above problems.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention is as follows. The work of the proposed road structure cleaning machine installed on a self-propelled vehicle includes cleaning work while the vehicle is running and stopping work while the vehicle is stopped and the outrigger is installed to stabilize the vehicle. . In any work, a cleaning tool is arranged at the tip of the arm, and the arm has an articulated mechanism and a swivel function. The cleaning tool is a set of three, and the operating mechanism is a handling mechanism. Cylindrical road structures (a) such as signs are to be held inside and clean the entire circumference of the cylinder.

Further, for a flat road structure B such as a protective wall, the cleaning tool can be changed to a flat type and can be easily cleaned. In addition, the guidance and tracking system for the distance between the structure and the cleaning machine includes contact sensors, non-contact sensors, displacement sensors, CCD camera sensors, monitors, controllers, hydraulic drive units, operating units, and cleaning machines. It consists of hardware consisting of and software that controls these, and does not depend on the skill level of the operator.

【Example】

 Examples will be described with reference to the drawings. On the vehicle body of the self-propelled vehicle 1, a rotatable platform 3 for pivotally supporting an arm of a road structure cleaning machine is pivotally mounted, and a first arm 4, a second arm 5, and a third arm 6 are mounted on the platform 3. Pins S, T, and U are connected in series, and hydraulic cylinders 7, 8 and 9 are provided to operate each arm, and each hydraulic cylinder has pins M, N, O, P, Q and R, respectively. Are serialized in. In the figure, 2 is an outrigger.

The third arm 6 and the center case 15 are connected by a pin X, and the center case 15 and the like rotate about the pin X 1 as a fulcrum because the hydraulic cylinder 14 is connected by the pins V and W. This is due to the expansion and contraction operation of the hydraulic cylinder 14. In addition, the opening / closing operation of the cleaning tool 11 and the side case 10 is based on the expansion / contraction operation of the hydraulic cylinder 12 which connects the center case 15 and the side case 10 to each other by the pins Z and Y.

Further, the rotation operation of the cleaning tool 11 is to transmit the rotation of the hydraulic motor 13 to each cleaning tool 11 to rotate the cleaning tool 11. The form of the three cleaning tools is based on the expansion / contraction operation of the hydraulic cylinder 12, and these operations are performed by the automatic control cleaning operation including the sensor section, control section, hydraulic drive section, etc. as shown in FIG. Becomes The contact sensor A detects the distance between the cleaning machine and the road structure when cleaning a flat surface such as a protective fence or a retaining wall.

The non-contact sensor B detects the distance between the cleaning machine and the sign, the guide pole, and the cleaning machine and the road surface. The displacement sensor D detects the operating angles of the first arm, the second arm, and the third arm. The CCD camera C captures the work status of the structure and the cleaning machine in a follow-up manner. The feedback signals from the above non-contact sensor, contact sensor, and displacement sensor are calculated by the control unit to calculate the direction and distance of the structure, and a correction command signal is output to the hydraulic actuator to follow the building and automatically guide the system. The control is performed smoothly.

The operation will be described together with the effect.

[0012]

[Effect of device]

 Since the present invention is configured as described above, it has the following effects. According to the present invention, in a road structure cleaning machine, a system for tracking a distance between a structure and a cleaning tool includes a contact sensor, a non-contact sensor, a displacement sensor, a sensor such as a CCD camera, a monitor, a controller, and a hydraulic drive. It consists of hardware consisting of parts, operating parts, cleaning machines, and software that controls these.For cleaning road structures, that is, protective fences, signs, guide posts, lighting posts, guide signs, retaining walls, etc. The adoption of the automatic control system does not depend on the skill level of the operator. In addition, it greatly contributes to the reduction of operator's fatigue, and the cleaning accuracy is made uniform, which makes it possible to provide a groundbreaking road structure cleaning machine.
