Description

  The present invention relates to a road surface obstacle recovery device attached to an appropriate traveling vehicle.

  When recovering luggage that has fallen on the road or waste on the road surface, especially on expressways, it is very dangerous if the recovery worker gets off the work vehicle and recovers it, so these obstacles remain on the vehicle. A work vehicle for recovering the vehicle has been known for some time.

  For example, in Japanese Examined Patent Publication No. 57-52446 (Patent Document 1), a recovery device provided with a clamshell bucket type gripping mechanism at the tip of a link arm (boom) is attached to a traveling vehicle body with a loading platform (recovered obstacle storage location). An attached work vehicle is disclosed.

  Japanese Utility Model Laid-Open No. 7-42373 (Patent Document 2) is provided with a pair of left and right booms that can be raised and lowered at the front part of a vehicle body, and can be tilted back and forth at the tip and supported on the road surface. There is disclosed a road surface cleaning vehicle provided with a bucket for collecting and storing dust that is provided with a vertical rotation brush for scraping casters and dust.

  In JP-A-10-306415 (Patent Document 3), a pulley driven by a grounding support wheel is provided with a horizontal axis rotary blade for scraping, and is mounted in front of a traveling vehicle via an elevating mechanism. A recovery device is disclosed in which a road surface obstacle is flipped up by a rotor blade and thrown into a storage location by traveling of the vehicle.

Japanese Patent Publication No. 57-52446. Japanese Utility Model Publication No. 7-42373. JP-A-10-306415

  The work vehicles disclosed in Patent Documents 1 and 2 for collecting obstacles from the known road surface described above have an obstacle gripping part and scooping part (hereinafter referred to as “collection mechanism part”) attached to the vehicle body. In addition, a mechanism that performs position control with a vertically rotating arm (boom) is employed, and thus various problems exist.

  Specifically, since the arm mechanism is employed, it is difficult to operate the arm while the vehicle is running to set the collection mechanism unit to the obstacle collection-possible position (grounding position). The operation of moving the collection mechanism to the position where it can be collected must be when the vehicle is stopped or when traveling at a slow speed close to the stop. For this reason, when an obstacle is discovered and recovered during the patrol traveling of the road surface condition, the recovery mechanism must be set to the installation position after being temporarily stopped, so the efficiency of the obstacle recovery work is poor.

  Further, in the mechanism that takes in an obstacle by the rotating body described in Patent Documents 2 and 3, if the rotational speed of the rotating brush or the rotating blade is slow, an effective scraping action cannot be exhibited, and if the rotational speed is fast. , Throwing away obstacles. Accordingly, if the rotational speed corresponding to the traveling speed is set, the vehicle speed at the time of the recovery work is specified, and there is a limit to the efficiency of the work. Furthermore, when an independent rotation mechanism is employed regardless of vehicle travel, the cost of the apparatus is increased.

  Further, when the collected obstacle is discarded, the collection device described in Patent Document 1 stores the collected material in the loading platform of the traveling vehicle and discharges it in a dump form, which requires a special vehicle body. In the collection device described in No. 3, it is necessary to take out and discharge from the storage location, and it is complicated to discard the collected material (dust). In particular, when the road surface obstacle (recovered material) is a small animal, there is a sanitary problem that the small animal must be in direct contact.

  Further, in the above-described known work vehicle, since the recovery mechanism unit does not include an independent left-right moving mechanism, the normal recovery range (lateral width range with respect to the traveling direction) is determined by the width of the recovery mechanism unit. If the width of the recovery mechanism is narrowed to reduce the weight of the part, the recovery range will be narrowed. As a result, if there are obstacles (objects to be collected) on the edge of the road surface, the vehicle may not be able to be recovered. Also, during normal collection work of obstacles on the road surface, Operation (moving left and right) is required, and collection work on a highway or the like also causes safety problems.

  Further, if the collection range of the collection mechanism section is expanded, there arises a problem that the collection mechanism section increases in size, and considering the safe driving of the vehicle, the maximum collection mechanism section width is limited to the maximum vehicle body width. This makes it difficult to collect obstacles at the road edge.

  Also, if the recovery mechanism part is made of a metal bucket structure, it is necessary to avoid contact between the road surface and the bucket, it is difficult to recover while traveling, especially in order to carry out obstacle recovery work while traveling, As in the collection mechanism disclosed in Patent Documents 2 and 3, a rotating brush must be attached so that an obstacle is taken into the collection mechanism.

  Therefore, the present invention proposes a novel road surface obstacle recovery device that can be easily mounted on a traveling vehicle and can collect obstacles while traveling, and further, it is easy to dispose of the recovered material. The present invention also proposes a road surface obstacle recovery device that is provided with a lightweight and small recovery mechanism and that is recovered in a range wider than the vehicle width.

  A road surface obstacle recovery device according to the present invention is formed of a box-shaped storage part having a front opening, wheels attached to the storage part, and an elastic plate having appropriate flexibility, and a front edge of the storage part A mounting mechanism portion that includes a recovery mechanism portion that includes a scraper that pivots around a position and whose tip contacts the ground, and a vertical movement mechanism that moves the recovery mechanism portion up and down, and attaches the recovery mechanism portion to a predetermined vehicle. It is characterized by comprising.

  Thus, a predetermined work vehicle is configured by mounting the road surface obstacle collecting device on the front surface of an appropriate traveling vehicle, and road patrol is performed on the vehicle, and obstacles (falling objects, dust) exist on the road surface. When it is discovered that the recovery mechanism unit is lowered so that the wheels of the recovery mechanism unit are in contact with the ground, the scraper is tilted forward, and the recovery mechanism unit passes through the obstacle (collection target) position, The obstacle is picked up by a scraper, stored in a storage unit, and the obstacle is collected from the road surface.

  A road surface obstacle collecting device according to the present invention (Claim 2) is the above road surface obstacle collecting device, wherein a collection bag of an appropriate size having an opening corresponding to the front opening of the storage portion of the collecting mechanism portion; The collection bag is provided with a bag mounting mechanism in which the collection bag is stored in the storage unit in a front opening state and is detachable.

  Thus, when the collection bag is attached as described above and the collection operation is performed, the collection item is taken into the collection bag, and the collection bag is removed after the operation is completed, and the collection item (dust: small animal) is discarded together with the collection bag.

  Further, the road surface obstacle recovery device of the present invention (Claims 3 and 4) is provided with a lateral movement mechanism for moving the recovery mechanism part to the left and right in the attachment mechanism part, and the lateral movement mechanism is attached to the attachment mechanism part. The rail portion is substantially the same as the vehicle width of the vehicle, and is connected to the collection mechanism portion side so as to travel and move on the rail portion, and includes a moving portion that is narrower than the lateral width of the storage portion.

  Thus, the horizontal movement of the recovery mechanism portion is realized, and the movement becomes a left and right range protruding from the length (horizontal width) of the rail portion, so that the recovery mechanism portion can be formed compactly.

  Furthermore, the road surface obstacle recovery device according to the present invention (Claim 5) includes: a telescopic arm projecting forward from the recovery mechanism unit; a vertical moving leg unit suspended from the distal end of the telescopic arm; A scraping mechanism portion composed of a scraping plate portion that is substantially coincident with the width of the storage portion and provided with a support wheel is provided at the lower end.

  Therefore, when the obstacle is collected, the telescopic arm is extended, the scraping plate part projects forward from the obstacle (object to be collected), and after being lowered, the telescopic arm is retracted to store the obstacle. It can be forcibly stowed up.

  Since the present invention (Claim 1) employs the above-described configuration, when an obstacle (recovery object) is found during road patrol in a work vehicle equipped with the apparatus of the present invention at the front, By lowering, grounding the scraper and traveling toward the obstacle, the recovery object is scooped up by the scraper, and traveling recovery is possible without the need for a recovery mechanism such as a brush, As a result, the weight of the recovery mechanism is reduced, and in combination with the recovery operation, the recovery operation is realized while ensuring the safe traveling of the work vehicle.

  Further, according to the present invention (claim 2), the collection bag is mounted in the storage unit of the collection mechanism unit, and the collection operation is performed in the collection bag for disposal at the same time as the collection operation of the obstacle. It is possible to easily dispose of the object (the collected obstacle), and particularly when the recovered object is a small animal, there is an advantage that the small animal can be disposed without direct contact and can be treated hygienically.

  In the present invention (Claim 3), the mounting mechanism portion is provided with a lateral movement mechanism for moving the collection mechanism portion to the left and right. Therefore, when an obstacle is found during road patrol on the work vehicle, the vehicle travels. In this state, the recovery mechanism is moved laterally in accordance with the position of the obstacle on the road, and the obstacle scooping and collecting operation is performed as described above. The recovery mechanism is smaller than the vehicle width. Can be realized.

  Further, according to the present invention (Claim 4), in particular, the lateral movement mechanism for laterally moving the recovery mechanism section is connected to the rail section that substantially matches the vehicle width of the mounted vehicle and the recovery mechanism section side so that the rail section travels. In addition, it is composed of a moving part that is narrower than the lateral width of the recovery mechanism part, so that the recovery mechanism part can be protruded laterally from the work vehicle main body, so that the vehicle is moved toward the road edge. Therefore, it is possible to collect obstacles in the vicinity of the road edge while the vehicle is running.

  Further, according to the present invention (claim 5), a scraping mechanism portion is provided in the recovery mechanism portion. For example, a road edge facility such as a curb block, a side wall, or a guardrail whose obstacle is a boundary such as a green belt. If the vehicle is approaching the road edge with the recovery mechanism protruding to the side of the vehicle body, the recovery mechanism may come into contact with roadside facilities such as curbs. Therefore, even when recovery in the running state is impossible, the recovery mechanism can be recovered by scraping the obstacle. As described above, even if the position of the obstacle on the road surface and other conditions are inappropriate for traveling recovery, the operator can perform the recovery operation while in the boarding state, thereby ensuring the safety of the operator.

  First Embodiment FIGS. 1 to 5 show a first embodiment of the present invention. A road surface obstacle recovery apparatus shown in this embodiment includes a recovery mechanism unit 1 and a scraping mechanism unit 2. And the mounting portion 3.

  The recovery mechanism unit 1 includes a storage unit 11, wheels 12, and a scraper 13. The storage unit 11 is a metal box with a bag member attached to an appropriate frame body or a predetermined strength. It is a box body of a front opening having an appropriate structure. The wheel 12 has a position and a structure that can travel while supporting the entire recovery mechanism unit 1 and the entire scraping mechanism unit 2 described later.

  The scraper 13 is formed of an elastic plate having an appropriate flexibility such as a rubber plate or a plastic plate. The scraper 13 is provided so as to be pivotable about the opening front edge position of the storage portion 11 and can be appropriately rotated. It is provided with a drive unit and a drive control unit, and is rotated by the operation of an operator who is on the driver's seat or front passenger seat of the vehicle A equipped with this device.

  The angle with the ground contact surface when the scraper 13 is grounded is 15 to 25 degrees when the speed of the vehicle A for traveling recovery of an obstacle (collection target) B described later is planned to be 5 to 20 km / h ( Preferably, it is about 20 degrees), and when 10 to 40 km / h is planned, it is 10 to 20 degrees (preferably about 17.5 degrees). That is, when the ground contact angle is large in high-speed traveling, the obstacle (collection target) B is flipped up by the scraper 13, and the storage into the storage unit 11 is not smoothly performed.

  The scraping mechanism unit 2 is attached to the upper portion of the storage unit 11 of the recovery mechanism unit 1 and is attached to the upper and lower ends of the telescopic arm 21 projecting forward of the recovery mechanism unit 1 and the top and bottom of the telescopic arm 21. The moving leg portion 22 and the scraping plate portion 24 which is provided continuously with the lower end of the vertical moving leg portion 22 and substantially coincides with the width of the storage portion 11 and is provided with a supporting wheel 23. Of course, the telescopic arm 21 and the vertically moving leg portion 22 are provided with a drive portion and a drive control portion so as to be operated by the operation of a boarding worker.

  The mounting unit 3 is configured so that the recovery mechanism unit 1 equipped with the scraping mechanism unit 2 can move to a desired position (lateral movement and vertical movement) when the work vehicle is equipped with the apparatus. Thus, the vehicle body fixing portion 31, the rail portion 32, the lateral movement body 33, and the recovery mechanism portion support body 34 are configured.

  The vehicle body fixing portion 31 fixes the entire device to the front portion of the vehicle A, and includes appropriate connecting means to the bumper portion and chassis portion of the vehicle. The rail portion 32 is fixed to the front portion of the vehicle A by the vehicle body fixing portion 31 and is substantially matched with the vehicle width of the vehicle A.

  The lateral moving body 33 meshes with the rail portion 32 and can move along the rail portion 32, and the recovery mechanism portion support 34 is connected to the recovery mechanism portion 1 so as to support the recovery mechanism portion 1. The horizontal moving body 33 is connected to the front surface of the horizontal moving body 33 so as to be movable up and down. The horizontal moving body 33 includes a horizontal moving motor 331 and a vertical moving motor 332.

  The vehicle body fixing portion 31 is provided with a control box 35 that houses a control portion that controls each drive portion.

  Thus, the device is mounted on the front surface of the vehicle A at the vehicle body fixing portion 31, performs a road patrol in the vehicle A, and finds an obstacle B such as a fallen object or garbage on the road. Is collected while the worker is on board.

  That is, during normal travel, the scraper 13 of the collection mechanism unit 1 closes the front opening of the storage unit 11, and further operates the telescopic arm 21 and the vertically moving leg unit 22 of the scraping mechanism unit 2 to scrape the plate unit 24. Is positioned in front of the scraper 13 in the closed state so that the scraper 13 is not in the open state.

  When the obstacle B is found, the lateral movement motor 331 is driven according to the position of the obstacle B to cause the lateral movement body 33 to move laterally on the rail portion 32, and further the vertical movement motor 332 is driven. Then, the recovery mechanism unit support 34 is lowered, and the wheels 12 of the recovery mechanism unit 1 are grounded. At the same time, the scraping mechanism portion 2 is operated to move the scraping plate portion 24 from the position in front of the scraper, and then the scraper 13 is rotated to ground the tip.

  In this state, when the recovery mechanism unit 1 passes the position of the obstacle B, the obstacle B is scooped up by the scraper 13 and stored in the storage unit 11. After the obstacle B is stored, the vehicle returns to the normal traveling state as described above, and travels home while preventing the obstacle B from jumping out of the storage unit 11.

  In particular, when there is an obstacle (recovery object) B close to the roadside facility, the obstacle B is located immediately before the scraper 13 that approaches the obstacle B by slow driving and moves forward. The work vehicle A is stopped, the telescopic arm 21 is extended, the vertical moving leg portion 22 is then lowered, the support wheel 23 of the scraping plate portion 24 is grounded, and the telescopic arm 21 is retracted and scraped. When the plate portion 24 is pulled in the direction of the collecting mechanism portion 1, the obstacle B is slid on the scraper 13 by the scraping plate portion 24 and stored in the storage portion 11.

  Therefore, any recovery work can be performed while the worker is on board.

  <Second Embodiment> FIGS. 6 to 11 show a second embodiment of the present invention, and the road surface obstacle recovery device shown in this embodiment includes a recovery mechanism portion 1a and a mounting portion 3a. Is done.

  Similar to the first embodiment, the recovery mechanism unit 1a includes a storage unit 11a, wheels 12, and a scraper 13. The wheels 12 and the scraper 13 other than the storage unit 11a have the same configuration as in the first embodiment. It is.

  The storage portion 11a is formed in a horizontally long shape that substantially matches the width of the vehicle A, and includes a collection bag 14 and a mounting mechanism (locking hook) 15 for the collection bag 14.

  The collection bag 14 has a size that can be folded outward at the opening of the box-shaped storage portion 11 a that opens forward, and has a structure corresponding to the mounting mechanism (locking rod) 15. For example, if the mounting mechanism 15 is a plurality of locking rods 15 provided outward at the opening of the storage portion 11a, the collection bag 14 is provided with a string passing portion 141 at the opening to close the bag. An exposed portion 143 is provided through which the string 142 is passed and the string 142 is exposed from the string passing portion 141.

  The collection bag 14 has an exposed portion at the same time that the bag body is positioned in the storage portion 11a, the string passing portion 141 that is an open end is folded back to the outside of the opening portion of the storage portion 11a, and the string 142 is tightened. When the string 142 exposed from 143 is hooked on the locking rod 15, the collection bag 14 is attached to the storage portion 11a.

  The mounting portion 3a has basically the same structure as that of the first embodiment except for the lateral movement structure. That is, when the work vehicle A is equipped with this apparatus, the recovery mechanism 1a can move up and down.

  Thus, the device is mounted on the front surface of the vehicle A. When the device is used, a road patrol is performed on the vehicle A in a state in which the collection bag 14 is mounted in the storage portion 11a in advance, and a fallen object on the road. When an obstacle B such as a garbage is found, the obstacle B is collected while the worker is on board.

  That is, during normal traveling, the scraper 13 of the recovery mechanism unit 1a closes the front opening of the storage unit 11a, and when the obstacle B is found, the vehicle A is caused to travel so that the obstacle B is positioned in front of the traveling. At the same time, the collection mechanism 1a is lowered and the wheels 12 of the collection mechanism 1a are grounded. At the same time, the scraper 13 is rotated and its tip is grounded.

  In this state, when the recovery mechanism unit 1a passes the position of the obstacle B, the obstacle B is scooped up by the scraper 13 and stored in the storage unit 11a. After the obstacle B is stored, the vehicle returns to the normal running state described above, and the return trip is performed while preventing the obstacle B from jumping out of the storage portion 11a.

  In particular, in the present embodiment, the collection bag 14 is attached to the storage unit 11a, and thus the collected obstacle (collected material) B is stored in the collection bag 14 simultaneously with the collection. Therefore, the bag 14 of the collection bag 14 can be closed by removing the collection bag 14 from the opening of the storage portion 11a and pulling the string 142 after the collection operation, and can be discarded as it is.

  In many cases, the road surface obstacle B is a small animal bounced by a traveling vehicle. In such a case, the collection bag 14 is replaced every time the obstacle (small animal) B is collected, thereby contaminating the storage portion 11a. And there is an advantage that a small animal can be disposed of without being in direct contact with it, so that it can be treated in a sanitary manner.

  Also, as shown in FIGS. 9 to 11, a configuration is adopted in which a hook-and-loop fastener is employed as the mounting mechanism 15a of the collection bag 14a, and the hook-and-loop fastener (mounting mechanism) 15a is provided at a predetermined position of the collection bag 14a and a predetermined position of the storage portion 11b. It may be adopted.

  When the mounting mechanism 15a, which is easy to attach and detach, is employed, the automatic sealing mechanism 16 is attached to the storage portion 11b, and the recovery bag 14a can be automatically sealed.

  That is, inside the opening of the storage portion 11b, a receiving plate 161 is provided on the bottom surface, a pressing plate 162 that is movable upward and downward, and a vertical moving portion 163 of the pressing plate 162 is provided on both sides, and the receiving plate 161 and the pressing plate 162 are provided. If an automatic sealing mechanism 16 having a heating mechanism is provided on the inside and the collection bag 14a is formed of a heat-sealable material, the collection plate 14a is lowered by lowering the pressing plate 162 after the obstacle (collected matter) B is collected. By heat-sealing the opening, the recovered waste leaf can be made without touching the recovered material B at all.

  The device of the present invention is not limited to the above-described embodiments. For example, the specific configuration of the horizontal movement and the vertical movement of the recovery mechanism unit can be arbitrarily determined by adopting a hydraulic mechanism, and the storage unit is also provided. A box shape may be used, and the scraper is not limited to a single body, and strips may be arranged in parallel.
