The inspection device (1) allows the vehicle to be placed on a surmountable flat surface (floor surface). Thus, it is possible to provide a vehicle inspection device that is improved in that the vehicle inspection device itself can be moved and no auxiliary equipment is required to disengage the tire from the roller.
Description
Technical Field
The present invention relates to an inspection device configured to support a tire in a manner allowing the tire to spin idly for evaluation inspection of vehicle conditions.
Background
Patent document 1 discloses an auxiliary device for testing a vehicle. The auxiliary device comprises: a roller configured to support a wheel (i.e., a tire) in a manner that allows the wheel to rotate; a base frame supporting the roller in a manner allowing the roller to rotate; a frame facing the base frame; and a boarding plate mounted to the frame. The test assisting apparatus of patent document 1 is configured to be movable by using casters.
Patent document 2 discloses a vehicle inspection device configured to disengage wheels on free rollers by extending a plate member in a gap between the free rollers and thereby causing the wheels to travel along the tip of the plate member.
However, the test assisting apparatus of patent document 1 includes neither a fixing mechanism (i.e., a braking mechanism) for stopping rotation of the roller nor a mechanism for stopping idling of the wheel (tire), and after the test is completed, it may be difficult to replace the vehicle due to idling of the wheel. Therefore, the test assisting apparatus of patent document 1 is likely to require an accompanying apparatus such as a winch for externally applying a force to the vehicle (e.g., pulling the vehicle) in order to detach the wheel from the roller.
The vehicle inspection device of patent document 2 requires a space (i.e., a pit) formed on the floor below the free roller, for example, for placing a lifting device configured for the extension of the panel. This may reduce the flexibility in selecting the location where the inspection is to be performed.
Accordingly, there is room for further improvement in an inspection apparatus configured to support a tire in a manner allowing the tire to idle in order to evaluate the condition of an inspected vehicle, in consideration of the necessity of the presence/absence of an accessory device for detaching a wheel from a roller, and in consideration of the flexibility in selecting a place for performing inspection.

As shown in fig. 1 to 6, each of the tire supporting devices 2 includes rollers 15 (for example, four rollers 15 in the present embodiment), a housing 16, side rollers 17, a safety barrier 18, a shutter 19, a link mechanism 20, a limit switch 21, and a slope 22. The rollers 15 allow the tyre 4 to idle. The housing 16 supports the roller 15 in a manner allowing the roller 15 to rotate. The side rollers 17 are positioned to face corresponding one of the two sides of the vehicle 3. A security barrier 18 is mounted to the housing 16. A shutter 19 is included in the housing 16 and is configured to be movable up and down. The link mechanism 20 is configured to raise and lower the barrier 19. The limit switch 21 detects the elevation state of the shutter 19. Ramp 22 is removably mounted to housing 16.
The roller 15 is shaped cylindrically or cylindrically and rotatably supports the tire 4. Each roller 15 is made of a metal material such as stainless steel or iron, and includes a pair of end portions, each rotatably supported by the housing 16 via a bearing 23. As shown in fig. 2 and 3, the rollers 15 within the housing 16 have axes of rotation parallel to each other and are configured to rotate in the same direction. The rollers 15 in the housing 16 are arranged at predetermined intervals apart from each other. Each roller 15 has a length in its axial direction longer than the width of the tire 4.
The housing 16 is made of a metal material such as iron, and has a rectangular box shape. The housing 16 serves as a body of the inspection device 1, and is disposed or mounted on a floor (i.e., a plane on which the vehicle 3 can travel).
As shown in fig. 2 and 3, each pair of tire supporting devices 2 aligned in the vehicle width direction is coupled to each other via a coupler 24 having an elongated rectangular plate shape. In other words, each pair of housings 16 aligned in the vehicle width direction are coupled to each other via the coupler 24. The coupler 24 coupling each pair of the left and right tire supporting devices 2 may be used only for adjusting the center positions of the pair of the left and right housings 16 to be uniform, and may be removed after the adjustment is completed.
Each of the housings 16 is provided with three rollers 15 which are cylindrical or columnar in shape and mounted outside the housing 16. The three moving rollers 25 are made of a resin material such as polyurethane, have rotational axes parallel to each other, and are mounted to the housing 16 in such a manner as to rotate in the same direction.
Each housing 16 includes: a first end side to which two moving rollers 25 are mounted; and a second end side to which a moving roller 25 is mounted. The two moving rollers 25 on the first end side are mounted to the housing 16 in alignment along a direction (e.g., a vehicle front-rear direction) perpendicular to the rotational axes of the two moving rollers 25 in a plan view.
In detail, as shown in fig. 9 to 11, each of the moving rollers 25 is mounted to the housing 16 via a first supporting means 26, a second supporting means 27, and a third supporting means 28. The first support 26, the second support 27 and the third support 28 are made of a metallic material such as iron.
The first supporting means 26 includes a roller supporting portion 26a rotatably supporting the moving roller 25 and a mounting portion 26b overlapping the second supporting means 27.
As shown in the plan view of fig. 9, the roller support portion 26a has a substantially U-shape, and the moving roller 25 is interposed in the roller support portion in the direction of the rotation axis of the moving roller 25.
The mounting portion 26b is a rectangular plate-like member, and is mounted to the second supporting means 27 with four screw members 29 (e.g., bolts).
As shown in fig. 11, the second supporting means 27 has a substantially U-shaped cross section and includes a concave groove 27a at its center. The second supporting means 27 is provided below the mounting portion 26b of the first supporting means 26.
As shown in fig. 11, the third support means 28 has a substantially T-shaped cross section and is arranged below the second support means 27. The third supporting means 28 includes a convex portion 28a at the center thereof and flat portions 28b adjacent to both sides of the convex portion 28 a. The convex portion 28a is inserted into the concave groove 27a of the second supporting means 27 and is substantially equal in width to the concave groove 27a. The flat portion 28b is secured to the housing 16 with a screw member 30 (e.g., a bolt).
The mounting portion 26b of the first support means 26, the second support means 27 and the protruding portion 28a of the third support means 28 are penetrated by a set screw member 31 such as a bolt. A fixed spherical washer (i.e., a first spherical washer) 32 is interposed between the mounting portion 26b and the head of the set screw member 31.
The roller support portion 26a, which is the end of the first support means 26, is pressed downward (i.e., toward the floor) by operating an operating handle (not shown) mounted to the fixed spherical washer 32 and rotating a set screw member 31 screwed with (i.e., screwed into) the fixed spherical washer 32. This action of rotating (i.e., tightening) the set screw 31 presses the moving roller 25 down onto the floor, causing the housing 16 to be lifted and become movable.
The housing 16, which is the body of the inspection apparatus 1, is brought into contact with the floor by rotating (i.e., loosening) the set screw member 31, and is fixed to the floor or the like in a place for performing inspection by fixing the set bolt 33 extending through the housing 16 to the side rail 5. The side rail 5 is provided with a nut, not shown, for fixing the housing 16, i.e. fixing the inspection device 1.
As shown in fig. 1 to 4, the side roller 17 is rotatably mounted to and supported by the housing 16. The side roller 17 has a cylindrical or columnar shape, and restricts movement of the vehicle 3 in the vehicle width direction during inspection. The side roller 17 is made of a metal material such as stainless steel or iron. The side rollers 17 may be mounted to different positions depending on the tread width of the vehicle 3.
In detail, as shown in fig. 3, 4 and 8, the side roller 17 is rotatably supported by a supporting means 35 which is formed as an elongated rectangular plate and is mounted to the housing 16. The support means 35 is made of a metal material such as iron, includes a pair of end portions bent in the same direction, and has a substantially U-shape as a whole. In other words, the supporting means 35 includes a body 35a at the center thereof and a pair of supporting pieces 35b provided at both sides of the supporting means 35 and bent with respect to the body 35 a. The center of the body 35a in its longitudinal direction rotatably supports the side roller 17. As shown in fig. 3, each of the support pieces 35b is inserted in a groove 37 formed in the housing 16, and is fixed to the groove 37 by a mounting screw 38 such as a bolt.
Each groove 37 has a generally U-shaped cross section and, as shown in fig. 3 and 5, extends continuously in a straight line along the corresponding edges of the housing 16 at the vehicle front side and the vehicle rear side.
As shown in fig. 8, each slot 37 includes a pair of side walls, each of which includes a housing screw hole 39 through which a mounting screw member 38 extends.
By changing the selection of the housing screw holes 39 for fixing the support 35b, the support 35 is fixed to the housing 16 at a position corresponding to the tread width of the vehicle 3.
As shown in fig. 1, 3 and 4, the safety fence 18 is detachably mounted to the end of the housing 16 in the vehicle width direction and is positioned outside with respect to the side roller 17 in the vehicle width direction. The safety barrier 18 has a generally rectangular profile and, in a side view of the vehicle 3, has dimensions sufficient to cover a tyre 4 provided on the inspection device 1 to which the safety barrier 18 is mounted.
As shown in fig. 3, 5, 6 and 7, each baffle 19 includes a thin plate member having an elongated rectangular shape, and is made of a metal material such as iron. Each baffle 19 is disposed between two rollers 15 adjacent to each other. In other words, both sides of each baffle 19 face the roller 15. A baffle 19 is provided between two adjacent rollers 15. According to the present embodiment, three baffles 19 are provided between the four rollers 15. Each baffle 19 is disposed between the adjacent two rollers 15 in such a manner as to extend parallel to the adjacent two rollers 15. Each shutter 19 is configured to move up and down between the adjacent two rollers 15, and to butt the tire 4 provided on the rollers 15 by projecting through the gap between the rollers 15 after completion of inspection. Thus, during inspection, each shutter 19 is buried between the rollers 15 in such a way as not to come into contact with the tire 4.
The link mechanism 20 includes a first link mechanism 41 and a second link mechanism 42. The first link mechanism 41 rotatably supports a first end of the baffle 19. The second linkage 42 rotatably supports the second end of the baffle 19.
As shown in fig. 3, 6, 7, the first link mechanism 41 includes a first fixing piece 44, a second fixing piece 45, a first link 46, a second link 47, a lifting screw piece 48, and a lifting spherical washer (i.e., a second spherical washer) 49, and is provided in an end portion of the inspection device 1 on the vehicle outside in the vehicle width direction. The above-described components of the first link mechanism 41 are made of a metallic material such as iron.
The first and second fixing members 44 and 45 are fixed to the housing 16 with screw members 50 such as bolts. As shown in fig. 7, the first mount 44 is positioned closer to the vehicle 3 than the second mount 45, and is spaced apart from the second mount 45 in the vehicle width direction. The first fixing member 44 and the second fixing member 45 may be integrally formed as one piece.
As shown in fig. 6 and 7, each first link 46 includes a first end rotatably connected to a corresponding first end of the baffle 19 via a first connecting pin 52, and includes a second end rotatably connected to the first mount 44 via a second connecting pin 53.
The second link 47 includes a first end rotatably connected to the first end of the barrier 19 via a first connecting pin 52, and includes a second end threadedly connected to the end of the elevation screw 48 (i.e., threadedly connected to the end of the elevation screw 48). The second link 47 has a three-fork shape in plan view, including ends respectively connected to the different shutters 19.
The lifting screw 48 extends through a through hole 45a formed in the second fixing member 45. The inner diameter of the through hole 45a is larger than the diameter of the shaft portion of the elevation screw member 48.
The lifting spherical washer 49 receives the lifting screw member 48 extending therethrough, and is interposed between the second fixing member 45 and the head of the lifting screw member 48. The lifting spherical washer 49 is screwed with the lifting screw 48.
The lifting screw 48 is configured to move (i.e., reciprocate) forward and backward in the vehicle width direction with respect to the second fixing member 45 by rotating the lifting screw 48. This causes the second link 47 connected to the tip end of the lifting screw 48 to move forward and backward in the vehicle width direction (i.e., reciprocate).
As shown in fig. 6, the second link mechanism 42 includes a third mount 54 and a third link 55. The third link 55 is connected to the third mount 54 and the baffle 19.
The second link mechanism 42 is provided in an end portion of the inspection device 1 that faces the vehicle in the vehicle width direction. The above-described components of the second link mechanism 42 are made of a metallic material such as iron.
Each third link 55 includes a first end rotatably connected to a corresponding second end of the baffle 19 via a third connecting pin 56 and includes a second end rotatably connected to the third mount 54 via a fourth connecting pin 57.
In response to the forward and backward movement (i.e., the reciprocation) of the second link 47, the barrier 19 moves upward and downward in the height direction of the vehicle 3 while being supported by the first link 46.
As shown in fig. 7, the limit switch 21 is mounted to the housing 16 in such a manner as to be in contact with the corresponding shutter 19 when the shutter 19 comes to the upward limit position. The limit switch 21 outputs an ON/OFF signal representing contact/non-contact with the barrier 19 for monitoring the elevation state of the barrier 19.
Limit switches 21 may be mounted to housing 16 in such a way as to contact corresponding shutters 19 when shutters 19 come to the downward limit position. In addition, the limit switch 21 may be attached to a member of the link mechanism 20 instead of the housing 16, as long as the limit switch 21 can detect the lifted state of the shutter 19.
The ramp 22 is made of a metallic material such as iron and is detachably mounted to the vehicle front side and the vehicle rear side of the housing 16 as shown in fig. 1 to 5.
As shown in fig. 3-5, each ramp 22 includes a body 60 and an insert 61. The body 60 includes an inclined surface 60a configured to guide the tire 4 to the roller 15. The insert 61 includes an end that is inserted into a corresponding slot 37 of the housing 16. The body 60 has a cross section shaped as a substantially right triangle in which the inclined surface 60a is the hypotenuse of the triangle and serves as a continuous surface connecting the top surface of the housing 16 with the floor surface of the site where the inspection is performed.
The insert 61 has a substantially L-shaped cross section, and includes a flat portion 61a protruding from the body 60 and an insert portion 61b extending downward from the flat portion 61a in the vehicle height direction (i.e., in the downward direction in fig. 5). The insert 61 is formed by, for example, bending a rectangular plate into an L-shape.
As shown in fig. 3, each ramp 22 is detachably mounted to the housing 16 by inserting the insertion portion 61b of the insert 61 into the corresponding slot 37 of the housing 16 at a position displaced relative to the position at which the support 35b of the support means 35 is inserted. The insert 61 is positioned closer to the vehicle than the support 35b of the support device 35 in the vehicle width direction. The insertion portion 61b of the insert 61 is inserted into the groove 37 at a position closer to the vehicle than the support 35b of the support 35.
Thus, the ramp 22 and the side roller 17 are mounted into the same groove at different locations.
Each pair of tire supporting devices 2 whose positions are different from each other in the front-rear direction of the vehicle 3 are different from each other in terms of the length in the vehicle front-rear direction with respect to the slope 22 mounted to each pair of tire supporting devices 2. In other words, the length in the vehicle front-rear direction of the slope 22 mounted on the pair of left and right tire support devices 2a for idling the tire 4 of the front wheel of the vehicle 3 is different from the slope 22 mounted on the pair of left and right tire support devices 2b for idling the tire 4 of the rear wheel of the vehicle 3.
As described above, the inspection device 1 (i.e., the tire supporting device 2) may be provided or mounted on a flat plane (i.e., a floor surface) on which the vehicle 3 can travel.
Therefore, the inspection apparatus 1 eliminates the necessity of preparing a pit or a recess for accommodating various components (for example, the link mechanism 20 for lifting and lowering the shutter 19) on the floor at the time of installation, and contributes to an improvement in flexibility in selecting a place where inspection is performed.
The inspection device 1 (tire support device 2) includes a shutter 19 configured to interface with the tire 4. This allows the vehicle 3 to ride on and off the inspection device 1 by a self-propelled device without the need for an accompanying device, such as a winch.
The inspection device 1 (tire supporting device 2) is configured such that a shutter 19 is provided between the rollers 15 and fills the gap between the rollers 15. This helps to keep the roller 15 from pinching the operator's finger. Therefore, the inspection device 1 (tire supporting device 2) contributes to improvement of operation safety because the shutter 19 is provided between the rollers 15.
The inspection device 1 (tire supporting device 2) includes a limit switch 21. This is advantageous in grasping whether or not in a state in which the tire 4 of the vehicle 3 is allowed to ride on or leave the roller 15.
Thus, at the time of inspection, the inspection device 1 allows an inspector to easily monitor or inspect whether the tire 4 of the vehicle 3 can ride on or leave the roller 15.
Each tyre supporting device 2 comprises three moving rollers 25 rotatably mounted to the housing 16. This allows each tire supporting device 2 to be easily moved by the rotation of the movable roller 25 while maintaining the posture of the housing 16 horizontally. In particular, when the tire supporting device 2 is moved by the rotation of the moving rollers 25, the three moving rollers 25 allow the tire supporting device 2 to move in a direction inclined with respect to the rolling direction of the rollers 15 in plan view (in other words, in a direction in which the tire supporting device 2 is rotated in plan view). This facilitates fine tuning of the arrangement of the tire support device 2.
Each pair of tire supporting devices 2 aligned in the vehicle width direction is coupled to each other via a coupler 24 that is an elongated rectangular plate.
This allows each pair of the tire supporting devices 2 aligned in the vehicle width direction to match the center positions of the left and right pair of housings 16, and allows the left and right pair of housings 16 to match the positions of the projections and depressions due to the rollers 15. This allows each pair of left and right tires 4 to idle on the roller 15 under substantially the same conditions. Therefore, the inspection device 1 allows each pair of the left and right tires 4 to idle under substantially the same conditions, thereby contributing to an improvement in the accuracy of inspection.
The inspection device 1 (tire supporting device 2) includes a side roller 17. This suppresses the vehicle 3 from moving in the vehicle width direction (i.e., rushing out) during the inspection, thereby suppressing the vehicle 3 from falling off the inspection device 1 (tire supporting device 2).
The inspection device 1 (tire supporting device 2) is configured to allow the mounting position of the side rollers 17 to be changed according to the tread width of the vehicle 3 so as to accommodate vehicles having various tread widths.
Each tire supporting device 2 is movable in a state in which the slope 22 has been removed. This facilitates the mounting of the tire support device 2 according to the wheelbase length of the vehicle 3.
The ramp 22 is detachably mounted to the tire support device 2. This facilitates movement and storage of the tire support device 2.
Each pair of tire supporting devices 2 that are different from each other in position in the vehicle front-rear direction is different from each other in terms of the length in the vehicle front-rear direction with respect to the slope 22 that is mounted to each pair of tire supporting devices 2.
This results in a different contact time between the ramp 22 and the tires 4 of the front wheels of the vehicle 3 than between the ramp 22 and the tires 4 of the rear wheels of the vehicle 3, and reduces the force required by the vehicle 3 to ride on the ramp 22.
This allows the vehicle 3 to be easily ridden on the tire supporting device 2 by a self-propeller or on the tire supporting device 2 by the manual force of an operator without the need for an accessory device, and facilitates the implementation of an inspection with the inspection device 1.
Each tyre supporting device 2 comprises a support 35b of the supporting device 35 and an insert 61 of the ramp 22, both of which are inserted in the slot 37 of the casing 16.
Thus, each tire supporting device 2 is configured such that the ramp 22 and the side rollers 17 are mounted into the same groove. This helps to simplify the structure of the tire supporting device 2 for mounting the ramp 22 and the side rollers 17, thereby improving productivity while reducing costs.
Each tyre supporting device 2 comprises a safety barrier 18 removably mounted at a position further external than the side rollers 17. This ensures safety against the rotating tyre 4 becoming entangled during inspection. Therefore, the inspection apparatus 1 helps to ensure safety during inspection.
While the specific embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, but various modifications may be made without departing from the intention of the present invention.
For example, the inspection device 1 may be modified to provide the tire support device 2 for only a portion of the tires 4 of the vehicle 3.
Further, the number of the rollers 15 in each housing 16 is not limited to four, but may be plural other than four.
