Description

  The present invention relates to a vehicle wheel fixing device for fixing a vehicle wheel in a vehicle inclination angle measuring device or the like.

  In various cases in use and handling of a vehicle, it is necessary to fix the vehicle itself. In this case, various fixing methods can be considered, but if roughly divided, the vehicle body itself such as the frame structure on the vehicle bottom side is fixed, and the wheel that is easily visible and easy to handle from the outside. The case where it fixes itself is mentioned.

For example, in a vehicle, it is necessary to examine various characteristics.
For one, it is necessary to investigate how much the vehicle can tilt and withstand the tilt. The reason is that it is difficult to ensure the safety of the vehicle if the vehicle tilts easily for some reason.
For this reason, as a vehicle safety standard, an “inclination angle” (for example, 30 ° or 35 °) that is a guideline for preventing the vehicle from toppling is legally determined, although it varies somewhat depending on the vehicle type.

It is a vehicle inclination angle measuring device that examines the inclination angle. In this device, after the inspection vehicle is carried into the tread board serving as a measurement area, the free end side of the tread board is lifted, The inspection vehicle is intentionally tilted to the legal tilt angle.
Specifically, the front and rear wheels on one side of the loaded vehicle are brought into contact with wheel stops such as protrusions provided on one side on the tread board. The wheel stopper is a member for stopping the wheel from slipping when the vehicle is tilted. The front and rear wheels on the opposite side before the tread board tilts are in a free state.
Next, in this state, the free end side of the tread board is pushed up and inclined by a driving means such as a hydraulic cylinder provided with a link mechanism with the wheel stop side as a fulcrum. This inclination angle is a legal angle and is determined to be, for example, 30 ° or 35 ° depending on the vehicle type.

When the legal inclination angle is 30 °, if the front and rear wheels (wheels on the free end side) in the free state of the vehicle are all separated from the surface of the tread board (the ground contact surface), the vehicle is inclined at 30 °. “Fail” is determined. At this time, if either one of the front and rear wheels or both wheels are in contact with the surface of the tread board, the vehicle is determined to be “pass” at an inclination angle of 30 °.
Of course, it is performed in the same manner as described above even when the legal inclination angle is 35 °.

In this way, the tread board is pushed up sequentially and tilted, but of course, the vehicle for inspection also tilts, and when the vehicle approaches the statutory tilt angle (for example, 30 ° or 35 °), the vehicle itself May fall. Especially in the case of unacceptable vehicles, the risk of falling is increased.
For this reason, conventionally, in this type of vehicle inclination angle measuring device, in order to prevent the vehicle from toppling during the measurement, a toppling prevention means and device are generally provided.

FIG. 13 is an example of a tipping prevention device in a conventional vehicle tilt angle measuring device.
In the figure, reference numeral 10 denotes a tread board in the vehicle tilt angle measuring device (plan view), and a protruding wheel stopper 11 is provided on one side of the upper side in the figure. The wheel stopper 11 is brought into close contact with the front and rear wheels 51a, 51a on one side of the vehicles 50A, 50B for inspection (in this example, 50A is a small vehicle and 50B is a large vehicle). At this time, the front and rear wheels 51b, 51b on the other side are in a free state.

In this state, the side opposite to the wheel stopper 11 of the tread base 10 is pushed up by a driving means such as a hydraulic cylinder (not shown), but the vehicles 50A and 50B are naturally inclined.
In particular, when the “pass / fail” of the inclination angles of the vehicles 50 </ b> A and 50 </ b> B is determined, for example, when approaching 30 ° or 35 °, the vehicle itself may fall.
For this reason, in this example, the pulling wires 13 and 13 for fixing the wheel (the front wheel and the rear wheel 2 are adjusted) by the hydraulic cylinders 12 and 12 provided on the back side of the tread base 10. This) is attached as a component (member) of the fall prevention device.

The lead-in wires 13 and 13 are pulled out from the bottom surface side of the tread board 10 at the time of measurement, and are attached to predetermined parts of the vehicles 50A and 50B to prevent the vehicle itself from falling. Depending on the bottom structure, the mounting method is limited.
For example, in the case of a large truck, the bottom structure of the vehicle is often visible from the outside. Therefore, the lead-in wires 13 and 13 are attached to a strong part such as an exposed bottom frame structure part on the bottom side of the vehicle. be able to.
However, in many small vehicles such as large buses and passenger cars, the bottom structure portion of the vehicle is often not visible from the outside. In this case, the undercarriage parts such as the axle are selected, 13 need to be attached. At this time, since the wheel with the highest visibility from the outside of the vehicle is the wheel on the free end side, it is often attached to this wheel side.
Of course, even in the case of a large truck, it can be attached to the wheel side.

In the case of the lead wires 13, 13, there are various problems as follows.
First, pulling out and handling of the lead-in wires 13 and 13 is dependent on the hand of the worker, and therefore, the worker is apt to cause variations in the work. In other words, a certain level of work experience and skill are required.
For example, in the inside of the tread board 10 from which the lead-in wires 13 and 13 are pulled out, the frame structure portion has irregularities. Therefore, at the time of this drawing, the pull-in wires 13 and 13 run on the convex portions of the frame structure portion , It may get caught in the uneven part.
At this time, the worker needs the skill and skill to detect this situation.

  When the lead-in wires 13 and 13 run on the convex part of the frame structure part or are hooked on the uneven part, the leading ends of the lead-in wires 13 and 13 are attached to predetermined parts of the vehicle, and the vehicle is tilted in this state. Since a large load is applied to the lead-in wires 13 and 13, there is a possibility that it suddenly comes off from the riding part or the uneven part. As a result, the lead-in wires 13 and 13 suddenly loosen, and there is a risk that the vehicle is loosened or released, resulting in a serious accident.

  Further, the lead wires 13 and 13 are considerably heavy, and are quite long, and further, due to their rigidity, they are quite hard, so that they are not free and are difficult to pull out and handle.

In the case of this example, since the apparatus is a combined type of a large vehicle and a small vehicle, the drawing ports 14 and 14 of the drawing wires 13 and 13 need to be provided in a portion that can be drawn into the wheels of both vehicles. . In this case, as illustrated in FIG. 11, the drawer openings 14 and 14 are not necessarily in an optimum position with respect to the wheels of each vehicle.
In particular, in the case of the small vehicle 50A, since the drawer openings 14 and 14 are quite apart from each other, the load due to the attachment of the lead-in wires 13 and 13 causes external stress on the attachment parts such as wheels and axles. It is easy to become. For this reason, in the worst case, the tire may come off, parts such as bearings may be excessively stressed, deformed, or cause a failure.

Further, as described above, the pull-out and handling of the lead-in wires 13 and 13 are likely to vary depending on the operator, and also in the selection of the attachment site of the lead-in wires 13 and 13, the mounting method and the fixing method. , It is easy for the workers to be loose.
In other words, it is difficult to standardize work and to secure work quality.

FIG. 14 is an example of another conventional fall prevention device.
In the figure, reference numeral 20 denotes a tread base in the vehicle tilt angle measuring device (side view), and one side surface on the left side in the figure is rotatably attached to the pit P by a hinge 21, and a protruding wheel is provided on the upper surface thereof. A stop 22 is provided.

In this state, the opposite side of the tread board 20 to the wheel stopper 22 is pushed up by the hydraulic cylinder driving means 30 having the link mechanism 31 installed in the pit P, and the vehicle 50C for inspection is tilted. At this time, when approaching the vicinity of 30 ° or 35 ° for determining “pass / fail” of the legal inclination angle, the vehicle 50C may be overturned as in the case of other vehicle inclination angle measuring devices.
For this reason, in this example, the fall prevention device 40 is attached to the back side of the free end side where the tread board 20 is lifted.

  In this fall prevention device 40, the retracting belt 41 fixed to the free end side of the vehicle 50C is guided to the fall prevention device 40 side through the outside of the free end side of the tread base 20, and the belt 41 is in a free state. The free end side is fixed by operating a belt fixing means 43 having a complicated structure by a fixing cylinder 42.

In the case of this overturn prevention device 40, there are the following problems.
First, it is unclear where to fix the vehicle. As estimated from FIG. 12, the belt 41 seems to be attached to a frame structure portion such as a door column on the side surface of the vehicle. In this case, since a considerable load is applied to the attachment portion at the time of measurement, In the worst case, the vehicle may be damaged.

  Further, the deep pits P are necessary in view of the vertical arrangement of the fixing cylinder 42 in the overturn prevention device 40 and the size of the driving means 30 of the hydraulic cylinder having the link mechanism 31 of the tread base 20. If the pit P is deep, an increase in cost is inevitable.

  In addition, although the belt 41 in the fall prevention device 40 is not shown in the drawing, there is a concern that a sufficient pressure-bonding strength cannot be obtained because the belt portion actually mounted on the table is pressure-bonded and fixed by driving the cylinder.

  The present invention provides a wheel fixing device for a vehicle that can be fixed easily and quickly in fixing the wheel in such a vehicle inclination angle measuring device.

  According to the first aspect of the present invention, there are provided a tread base on which wheels of a vehicle are mounted, a wheel presser covering the upper surface side of the wheels mounted on the tread base, and a plurality of arrays in the front-rear direction of the wheels on the tread base side.

It is the schematic plan view which showed the other example of the vehicle inclination-angle measuring apparatus of this invention which attached the wheel fixing device of the vehicle of this invention. It is the partial notch top view which showed the conventional vehicle inclination-angle measuring apparatus. It is the schematic explanatory drawing which showed the conventional vehicle inclination angle measuring apparatus.

An example of the vehicle fixing device according to the present invention is schematically shown in FIGS. 1 and 2.
1 and 2, reference numeral 100 denotes a vehicle wheel fixing device, and 110 denotes a tread board.
The tread board 110 may be a floor lower surface member depending on the application in which this apparatus is used (attached). In this example, as will be described later, since it is assumed that it is attached to the vehicle inclination angle measuring device, it is used as a tread board for a carry-in portion into which a vehicle for inspection is carried.

  120 is a wheel press that covers the upper surface side of the wheel 51 placed on the tread board 110, and 130 is a plurality of arrays (at a predetermined interval, etc.) in the front-rear direction on the tread board 110 side of the wheel 51 that is covered by the wheel press 120. Fixed locking part 140 is a moving locking part installed on one side of the wheel 51 of the fixed locking part 130 so as to be movable, and 150 is a locking part movement for moving the moving locking part 140 freely. Means 160a is a first bundle that is stretched between one side of the wheel press 120 and the fixed locking portion 130, and 160b is stretched between the other side of the wheel press 120 and the movement locking portion 140. The second unity body.

As long as the wheel press 120 is a kind of wheel upper surface cover having a function of pressing the wheel, the shape, material, and the like are not particularly limited, but preferably, a wide belt made of cloth or the like is used. In the case of cloth, it is lightweight and therefore easy to handle.
In particular, in the case of a vehicle tilt angle measuring device, an ideal measurement state can be obtained because the external load on the wheel is reduced as much as it is lighter. In this measurement, it is ideal that the external load is small on the free wheel, that is, the wheel on which the wheel presser 120 is put.
Moreover, since the outer diameter of the wheel and its width differ depending on the vehicle, it is advisable to prepare several types in advance. Thereby, it becomes possible to respond quickly to any wheel of a small vehicle or a large vehicle. Of course, good workability and reliable fixing can be obtained.

As long as the 1st binding body 160a and the 2nd binding body 160b also have a binding function which has sufficient intensity | strength, the shape, a raw material, etc. will not be specifically limited.
In this example, a cloth belt is used. Not only this belt place, but also a string or rope bundled in a belt shape may be used.

The first bundled body 160a and the second bundled body 160b need to be attached to the left and right ends of the wheel presser 120 during use, but the attachment method is not particularly limited.
In this example, as an example, each end of the wheel presser 120 is provided with a semi-circular and string-like hook 121, 121, while the end of each bundled body 160a, 160b has a hook-shaped hook. Tools (metal fittings) 211 and 211 are provided, and these members constitute engaging means 210a and 210b to be engaged with each other.
In this case, the wheel retainer 120 may be attached only by hooking the hook members 211 and 211 of the binding bodies 160a and 160b to the hook portions 121 and 121, respectively.
Therefore, the mounting work is simple and good workability can be obtained. Of course, the installation state does not vary depending on the operator, and a reliable installation state can be obtained.

The engaging means 210a and 210b are not limited to this case. For example, the hook portions 121 and 121 of the wheel presser 120 may be simple hook holes provided at the end portions. Or it is good also as a structure which provided the same hook tool engaged with the hook tools 211 and 211 by the side of each binding body 160a, 160b in the edge part. At this time, the hooks 211 and 211 side can be changed from a bowl shape to a semicircular or ring shape.
That is, the engaging means 210a and 210b include a wide variety of engaging modes.

In the case of the first bundled body 160a and the second bundled body 160b, when used, the other end portion is also located on the side of the wheel 51 to be fixed, the fixed locking portion 130 of the tread board 110, or the wheel 51 side. It is necessary to attach to the movement locking part 140 located in the direction.
Specifically, as shown in FIGS. 1 and 2, the end of the first bundle 160a is attached to the fixed locking portion 130 on the rear side of the wheel 51, and the end of the second bundle 160b is It is attached to the movement locking part 140 on the front side of the wheel 51.

This attachment method is not particularly limited. In this example, as an example, hook devices (such as metal fittings) 221 and 221 such as saddles are provided at the ends of the binding bodies 160a and 160b as in the attachment of the wheel presser 120.
And in the 1st binding body 160a, the hook tool 221 should just be hooked on the fixed latching | locking parts 130, such as a hook pin of the tread board 110. FIG.
Here, the hook device 221 and the fixed locking portion 130 constitute an engaging means 220a to be engaged with each other.

On the other hand, in the second binding body 160b, the hook member 221 only needs to be hooked on the annular hook member 141a such as the universal joint 141 provided on the movement locking portion 140 side.
Here, the hook member 221 and the annular hook member 141a such as the universal joint 141 constitute the engaging means 220b to be engaged with each other.
An example of the universal joint 141 is as shown in FIG. 3, in which an annular hook 141a is attached to a mounting bolt 141b so as to be rotatable and swingable.
By such engagement means 220a and 220b, attachment work is simple and good workability can be obtained. Of course, the installation state does not vary depending on the operator, and a reliable installation state can be obtained.

As shown in FIG. 2, the movement locking portion 140 is made of, for example, a block member, and an engagement portion such as a recess that engages with a guide rail 142 provided on a frame structure portion on the tread board 110 side on the bottom surface side. It is provided so that it can move freely.
Of course, as shown in FIG. 1, the moving direction (arrow A) is the direction of the guide hole 111 on the side of the wheel board 110 on the side of the wheel 51 and parallel to the arrangement direction of the fixed locking portions 130.

The locking portion moving means 150 is attached to the movement locking portion 140. For example, in the case of a hydraulic cylinder, the tip of the piston rod 151 is connected.
Therefore, when this hydraulic cylinder is driven, the movement locking portion 140 can be freely moved in the front-rear direction of the arrow A as shown in FIG.
If the movement locking part 140 moves in the front-rear direction, the second bundle 160b is pulled or loosened in FIG.
That is, when pulled, the overall tension of the wheel presser 120 and the first bundled body 160a associated with the second bundled body 160b increases, and the wheel 51 is reliably fixed.
On the contrary, when loosened, the overall tension of the wheel presser 120 and the first bundled body 160a associated with the second bundled body 160b is lowered and loosened, so that the fixation of the wheel 51 is released.

The fixing and releasing of the wheel can be easily and quickly performed by driving the hydraulic cylinder. Furthermore, the wheel can be fixed reliably and optimally. Of course, the fixed state does not vary depending on the worker. A stable, high-quality fixed state is always obtained.
This hydraulic cylinder is installed horizontally. For this reason, space saving in the vertical direction is achieved, and as a result, the pit depth may be shallow and the thickness (height) of the frame structure portion of the tread board may be thin, thereby reducing the cost. . Further, in the case of horizontal installation, there is room in space, and the hydraulic equipment can be enlarged correspondingly, and a reliable fixed state can be obtained.

As shown in FIG. 4, the universal joint 141 portion of the movable locking portion 140, particularly the annular hook 141 a, is housed inside the tread board 110 so as not to be an obstacle to the carry-in vehicle.
However, when using the wheel fixing, it is preferable that the hook 221 of the second bundle 160b is easily hooked when the annular hook 141a is slightly lifted.
For this reason, as shown in FIGS. 4 and 5, a kind of cam member 143 having a curved cam portion 143a at the tip thereof in the passage space portion of the moving annular hook 141a together with the movement locking portion 140 is provided. It is provided.
Accordingly, before the hydraulic cylinder is driven, as shown in FIG. 5 (a), the annular hook 141a is stored in the downward direction. When it starts to move, as shown in FIG. 5B, the annular hook 141a comes into contact with the cam portion 143a of the cam member 143 and rides up, so that it is slightly lifted.
By this lifting, the hook 221 of the second binding body 160b can be easily hooked, and the hook 221 and the fabric portion at the end of the second binding body 160b are attached to the peripheral edge of the guide hole 111 on the tread board 110 side. It is also possible to prevent rubbing.

The locking portion moving means 150 is not limited to a hydraulic cylinder.
For example, the engaging part moving means 150 may be an electric motor, and the moving engaging part 140 may be moved by its rotation. Further, a screw shaft transmission mechanism that moves the movement locking portion 140 by meshing a female screw portion provided on the block member side of the movement locking portion 140 with a rod-shaped screw shaft and rotating the screw shaft with an electric motor. Alternatively, a belt transmission mechanism that moves the movement locking portion 140 by passing a belt between the block member of the movement locking portion 140 and the electric motor and rotating the belt with the electric motor may be used.

In the case of the vehicle wheel 51, except for a special vehicle wheel (bare wheel), there is usually a tire house (fender) for mudguard, as shown in FIGS. 1 and 2, respectively. The middle (midway) between the first bundle 160a and the second bundle 160b is pulled in by intermediate pull-in locking means 170a, 170b of a hook device (such as a metal fitting) as shown.
The shape, structure, material and the like of the hook device are not particularly limited as long as they have sufficient strength and have a function of locking.
In this example, a hook-shaped hook portion 171a is provided on the tip end side, and this is hooked on the fixed locking portion 130 on the tread board 110 side. On the other hand, the opposite base end side is a triangular ring portion 171b.
For example, through this portion, the bundles 160a and 160b are passed in advance. Of course, this attachment method is an example, and the present invention is not limited to this.

In the case of this attachment method, since the hook is simply hooked, the binding bodies 160a and 160b can be pulled in easily and quickly.
Here, since the outer diameters of the wheels are different depending on the vehicle, it is preferable to prepare several kinds of hooks in size (length) and the lengths of the binding bodies 160a and 160b in advance.
Thereby, it becomes possible to respond quickly to any wheel of a small vehicle or a large vehicle. Of course, good workability and reliable pull-in can be obtained.
Further, in order to smoothly cope with such various aspects, the interval between the plurality of fixed locking portions 130 and 130 arranged in the front-rear direction of the wheel 51 in the opening 112 of the tread base 110 is a desirable range. There is a need to set. For example, in this example, this interval is set to about 5 to 10 cm. The fixed locking portion 130 is not limited to the illustrated hook pin. It may be a ring-shaped hook ring or hook hook.

Further, when the binding bodies 160a and 160b are pulled in by the intermediate pull-in locking means 170a and 170b, as is apparent from FIG. 2, the wheels 51 are pulled and fixed almost vertically toward the tread board 110. Therefore, an almost ideal fixed state can be obtained.
That is, in the case of the 1st binding body 160a, naturally it is pulled just under a wheel. On the other hand, in the case of the second bundle 160b, since the tension is applied by the movement locking portion 140 on the side of the wheel, an outward force is applied, but the intermediate retracting locking means 170b. This is because pulling in the middle of the second bundle 160b also pulls directly under the wheel.
Therefore, the fixed wheels 51 are hardly adversely affected as in the conventional device of this type. For example, in the conventional apparatus, excessive stress may be applied to the wheel, the axle, and the like. For this reason, in the worst case, tires may come off, parts such as bearings may be excessively stressed, deformed, or cause a failure.

In the case of the axle fixing device 100 for a vehicle of the present invention having such a configuration, the following procedure may be used when using it.
(1) First, the wheel retainer 120 is put on the upper surface side of the wheel 51 of the vehicle carried into the tread board 110. Basically, you just need to put it.
(2) Next, although the order is not ask | required, the 1st binding 160a is attached to the one side of the wheel pressing member 120, and the 2nd binding body 160b is attached to the other side.
For these attachments, it is only necessary to hook the hooks 211 and 211 at the ends of the binding bodies 160a and 160b on the left and right hook portions 121 and 121 of the wheel presser 120, respectively.
In addition, the wheel presser 120 may be put on the wheel 51 in advance in a state in which the binding members 160 a and 160 b are attached to the wheel presser 120.
(3) After that, the order is not limited, but the first binding 160a is attached to the fixed locking portion 130 on the tread board 110 side, and the second binding body 160b is attached to the movement locking portion 140.
The first bundle 160a can be attached only by hooking the hook member 221 at the other end to the hook pin of the fixed locking portion 130. The second bundle 160b can be attached only by hooking the hook member 221 at the other end to the annular hook member 141a of the universal joint 141 on the side of the movement locking part 140.

(4) In this state, since the binding bodies 160a and 160b are in a slack state, the intermediate pull-in locking means 170a and 170b are attached between the middle and the corresponding fixed locking portions 130 and 130, respectively. .
For these attachments, it is only necessary to hook the hook portions 171a and 171b of the intermediate pull-in locking means 170a and 170b to the hook pins of the fixed locking portions 130 and 130.
In this case, the intermediate pull-in locking means 170a and 170b are passed through the bundles 160a and 160b in advance through the triangular ring portion 171b on the base end side.
Note that this step may be omitted for a bare wheel without a tire house.
(5) After that, in order to fix the wheel 51, it is only necessary to drive the hydraulic cylinder of the locking part moving means 150. The cancellation is the same.
These operations need only be an on / off operation of the hydraulic mechanism.
These series of operations can be performed easily and quickly, and no special experience or skill is required as in the prior art. Therefore, standardization of work is possible, and a significant improvement in work efficiency can be expected.

6 to 11 show an example of a vehicle inclination angle measuring device 300A provided with (attached to) the vehicle wheel fixing device 100 of the present invention.
6 to 11, the entire vehicle inclination angle measuring device 300 </ b> A is usually housed in the pit P. Reference numeral 310 denotes a tread base (also used as the tread base for the wheel fixing device 100) into which the inspection vehicle 50 is carried. The side base 310 (right side in FIGS. 6 and 7) is pivoted. It is pivotally attached via a wearing part (rotating part) 320 so as to be rotatable.

  On the other hand, a wheel stopper 330 made of a convex member or the like is provided on the surface (upper surface plate) of the tread base 310 on the pivot mounting portion 320 side. The wheel stopper 330 is brought into close contact with the front and rear wheels 51a, 51a on one side of the loaded vehicle 50.

On the bottom surface side of the tread base 310, lifting drive means 340 for lifting the free end side of the tread base 310 is installed. In this example, a hydraulic cylinder is used.
In this hydraulic cylinder, one end side (base end portion) 341 (left side in FIGS. 6 and 7) is on the bottom side of the pit P, and the tip of the piston rod 342 on the other end side is on the left side on the bottom side of the tread board 310. It is pivotally attached to each side so that it can rotate.
Therefore, when the hydraulic cylinder is driven to extend the piston rod 342, the tread board 310 is lifted from the horizontal state shown in FIG. 6 and inclined as shown in FIG. Thereby, a legal inclination angle such as 30 ° or 35 ° can be realized freely. Of course, the vehicle 50 carried into the tread board 310 is also inclined.
In addition, the structure which lifts the free end side of the tread board 310 is not limited to this case. A link mechanism in which a frame member that is opened and closed by a hydraulic cylinder or the like is provided on the bottom side of the tread board 310, and the tread board 310 can be tilted by opening and closing the link mechanism.

  In this way, when the free end side of the tread base 310 is lifted and approaches the inclination angle of 30 ° or 35 ° where the inclination of the vehicle 50 is determined, the free wheels 51b and 51b of the vehicle 50 are Floating from the surface (landing surface) increases the risk of vehicle falling.

For this reason, in the measuring device of the present invention, as described above, the two wheel fixing devices 100, 100 for the vehicle of the present invention are provided for the free wheel of the vehicle 50.
The two wheel fixing devices 100 and 100 are basically the same as the devices shown in FIGS. 1 and 2 although the arrangement of components is slightly different.
The wheel fixing devices 100 and 100 may be used according to the procedure described above.

In actual measurement, as described above, the inspection vehicle 50 is carried into the tread board 310 and the front and rear wheels 51 a and 51 a are brought into close contact with the wheel stopper 330.
In this state, the wheel pressers 120 and 120 are put on the free end side wheels 51b and 51b, and a series of operations are performed. First, the wheel fixing devices 100 and 100 are set.

Next, for example, in FIG. 8, the hydraulic cylinders of the locking portion moving means 150 and 150 are driven. That is, the piston rod is extended.
Thereby, since the movement locking portions 140 and 140 move and stop, the respective second bundles 160a and 160a are pulled with a predetermined pressure, and the free wheels 51b and 51b in the front and rear of the vehicle 50 are moved to the wheels. It is fixed by the fixing devices 100 and 10.
This state corresponds to the cases of FIGS.

In the measuring apparatus of the present invention, the front and rear free wheels 51b and 51b are fixed at the time of the horizontal state (before measurement) when the tread board 310 is not yet lifted.
Thereafter, if the legal inclination angle of the vehicle 50 is 30 ° or 35 °, the tread board 310 is quickly inclined until about 5 ° to 3 ° before that.
In this case, since the wheels 51b and 51b in the free state are fixed, there is almost no fear of the vehicle falling over and high safety is obtained. In addition, the workability can be improved by the quick inclination of the tread board 310.

Thereafter, the wheel fixing devices 100, 100 are driven to release the fixed free wheels 51b, 51b. The so-called original measurement system is entered.
After entering the measurement system, the inclination of the tread board 310 is slowly and gradually increased with great care. For example, it is performed at a level of 1 °.
At the same time, for example, visually, it is observed whether the free wheels 51b and 51b are floating away from the floor surface (grounding surface) of the tread base 310.
Then, if both of the free wheels 51b and 51b are slightly separated from the floor surface (ground surface) at or before the legal inclination angle, it is determined as “fail”.
In addition, if both of the free wheels 51b and 51b or one of them are in contact with the floor surface (ground surface) at the legal inclination angle, it is determined as “pass”.
The ground contact state of the wheel is not limited to visual determination. The presence or absence of grounding of the wheel may be determined by optical detection means in which a light emitter and its light receiver are installed on both sides of the grounding point of the wheel.

In the above measurement, when the determination is “failed”, since there is a high risk of the vehicle falling, the wheels 51b and 51b in the free state immediately brought into the non-fixed state are driven by the wheel fixing devices 100 and 100, It shall be fixed.
As a result, the risk of vehicle overturning immediately after measurement is avoided, and high safety is ensured.
After ensuring this safety, the tread board 310 is returned to the original horizontal state. Therefore, high safety can be obtained even when the measurement is finished. Of course, high speed can be obtained.
Although the determination of “pass” is not as high as the case of “fail”, the wheels 51b and 51b in the free state, which are immediately in the non-fixed state, are fixed because the risk of the vehicle falling is high as before. It is assumed that the devices 100 and 100 are driven and fixed.
Of course, the measurement end operation is also performed in this state. Thereby, as in the case of “fail”, high safety and high speed can be obtained.

FIG. 12 shows an example of a vehicle tilt angle measuring device 300B provided with (attached to) the vehicle wheel fixing device 100 of the present invention.
The basic configuration of the vehicle inclination angle measuring device 300B is substantially the same as that of the vehicle inclination angle measuring device 300A. In this example, the vehicle inclination angle measuring device 300B is a combined type of the small vehicle 50A and the large vehicle 50B. . Therefore, in this measuring apparatus, the wheel fixing devices 100 and 100 of two vehicles are attached for the free wheels of the small vehicle 50A and the large vehicle 50B, and the total number is four.

The fixing of the free wheels 51b and 51b of the inspection vehicles 50A and 50B in this measuring device may be performed according to the above-described procedure for using the wheel fixing devices 100 and 100.
In this measuring apparatus, the second bundles 160b and 160b on the large vehicle 50b side are
It is also possible to attach to the moving locking portions 140 and 140 on the small vehicle 50A side and drive and pull the locking portion moving means 150 and 150 of this portion.
That is, even if the movement locking portions 140 and 140 on the small vehicle 50A side are considerably separated from the wheel side of the large vehicle 50B, the second bundles 160b and 160b on the large vehicle 50B side are intermediate retracted locking of this portion. The means 170a, 170b is temporarily pulled into the wheel 51b, wheel 51b of the large vehicle 50B, and then folded back and attached to the movement locking portions 140, 140 on the small vehicle 50A side, so there is no particular problem. It is.
Thus, if a part of the mechanism is combined, the cost can be reduced.

In the above description of the present invention, a case where the present invention is applied to a wheel inclination angle measuring device has been described as an example of wheel fixing, but the present invention is not limited to this. Since it is a device that fixes the wheel rotation of the vehicle, it can also be applied to the vehicle fixing of the chassis dynamo measuring device.
It can also be used as a fixing device for an onboard vehicle such as a vehicle transport truck. Furthermore, it can be used as a fixing device for a loaded vehicle such as a vehicle carrier or a ferry. In this case, each floor is used as a tread board.

Further, when fixing these cylindrical articles, for example, thin steel plate coils and paper winding coils, if these articles are regarded as a kind of large wheels, they can be used as this fixing device, that is, an article fixing device. In addition, it can also be used as a wider variety of article fixing devices.
That is, the present invention includes various types of fixing devices as long as they do not depart from the central technology.
