Description

[Detailed description of the invention] [Industrial application field] This invention relates to a workbench device for damaged vehicles, which is mainly used to measure any deformation of the car body and repair damaged parts as necessary. This invention relates to a workbench device for a damaged vehicle, which allows the workbench to be raised and lowered stably and safely, and which makes it easy to place the damaged vehicle on the workbench wherever it is installed.

[Prior Art] Conventionally, a specially shaped frame template used for measuring front suspensions, floor pan plates, etc., has been used to measure damaged vehicles.
This was installed under the vehicle to measure the length and width of the underbody. However, in order to measure all types of vehicles with this method, it is necessary to prepare all templates specially designed for each vehicle, and therefore measurements using this template are limited to certain types of vehicles. Moreover, it could only be applied to specialized repairs of model vehicles whose body designs do not change frequently.

Therefore, in response to the various body designs of automobiles, the special public welfare system was developed in 1983 as a device that measures any deformation of the vehicle body and repairs damaged parts as necessary.
A workbench device for damaged vehicles is proposed in Japanese Patent No. -27135.

When using this device, a damaged vehicle is often placed on top of the device and the entire device is lifted to measure deformation or to repair the damaged portion. Therefore, the above-mentioned work has been carried out with a lift device attached to the lower surface of the workbench device for damaged vehicles, or by using a workbench device for damaged vehicles with the lift device fixed to the underside in advance.

[Problems that the invention aims to solve] However, the lift devices used in general repair shops, etc. are those in which a thick cylinder rod moves up and down, those in the shape of a diamond-shaped pantograph on a train, Alternatively, since most lift systems use screws, if a lift device is fixed to the bottom surface of the workbench device for a damaged vehicle, the top surface of the workbench device will be elevated by the amount of the lift device. Therefore, when placing a damaged vehicle on the top surface of this work platform device, the vehicle must be lifted by the height mentioned above, which becomes a very troublesome task. The floor is dug and a lift device is embedded in the dug-out part so that the workbench device is located at the floor level.

However, due to current land conditions, repair shops often have to be built on the second floor, and in the case of the second floor, it is not possible to dig into the floor as mentioned above, so it is necessary to embed the lift device. It was nearly impossible to use the work platform equipment for the damaged vehicle. In addition, in the case of the method in which the lift device is embedded, it is completely impossible to move the work platform device for damaged vehicles, which is very inconvenient when changing the layout within the repair shop. With lift equipment, when an unbalanced load is applied to the workbench, etc.
There remained concerns regarding safety.

Therefore, in view of the above-mentioned problems, this invention allows a damaged vehicle to be easily placed without digging into the floor when installing a work platform device for a damaged vehicle, and can also be easily moved and installed. Moreover, the present invention has been devised for the purpose of stably and safely raising and lowering the work platform device for a damaged vehicle.

[Means for Solving the Problems] This invention provides a workbench for damaged vehicles that supports a damaged vehicle on a rectangular frame, measures the deformation of the vehicle body, and repairs damaged parts as necessary; It consists of a lift device that raises and lowers a vehicle work platform, and the damaged vehicle work platform has a rectangular frame that is wide enough to place the damaged vehicle and thick enough to be inserted under the damaged vehicle. The rectangular frame is formed into an elongated rectangular frame shape, and a measuring rod for damaged vehicles,
The lift device is formed with a mounting groove for mounting a measuring member or a tensioning device for repair, etc.
A base that can be stored in approximately the middle part of the rectangular frame, and a base that can be stored in the base and has an X-shape with the approximately middle part as a fulcrum, and its two lower open ends can be opened and closed by the base. It consists of a lift arm that is held and raises and lowers the rectangular frame by supporting it with its two upper open ends, and a lifting device that presses the lift arm in a direction where the X-shape becomes vertically long and lifts the rectangular frame. , the lift arm is provided with a stopper that prevents the X-shape from moving in the direction in which it becomes horizontally elongated, and that can be released by remote control. The above-mentioned problem is solved by disposing the arm so that it does not protrude upward from the rectangular frame when the arm is stored, and by forming the base to have a sufficient size to prevent the rectangular frame from tipping even if an unbalanced load is applied to it. It is something.

[Embodiment] An embodiment of this invention will be described below with reference to the drawings.

That is, the reference numeral 1 shown in the figure is a rectangular frame of a workbench for a damaged vehicle, which is composed of a longitudinal member 2 and a width member 3, and has a width sufficient to place the damaged vehicle as a whole, and has a width sufficient to support the damaged vehicle. It is formed into an elongated rectangular frame having a thickness that can be inserted under the frame 1, and a measuring rod for damaged vehicles, a measuring member,
Alternatively, a mounting groove 32 is formed to attach a tensioning device for repair, etc., and within this rectangular frame 1, reinforcing members 4 are installed in parallel to the widthwise member 3 at approximately equal thirds of the longitudinal member 2. Each is provided.

On the other hand, the lift device for raising and lowering the work platform for damaged vehicles has the following structure.

That is, reference numeral 5 denotes a base, which can be stored in the middle part of the frame surrounded by the longitudinal member 2 of the rectangular frame 1 and the two reinforcing members 4, and which is capable of applying an unbalanced load to the rectangular frame 1. It is made of a rectangular frame that is large enough to prevent it from tipping even when it is on the rise.

A lift arm 6 is held on this base 5.

This lift arm 6 consists of two rectangular frames 7 and 8, and the width of one rectangular frame 7 is the same as that of the other rectangular frame 8.
The rectangular frame 7 and rectangular frame 8 are made to have the same length and are slightly narrower than the inner width of It is formed in an X-shape.

Then, one open end 12 of the two lower open ends 12 and 13 in the X-shape of this lift arm 6 is connected to the width direction frame member 10a of the base 5,
The width direction frame member 10 is pivotably supported on one width direction frame member 10a side of the width direction frame members 10b, and the other lower open end 13 is on the side facing the width direction frame member 10a.
It is formed so that it can be slid freely in the direction of the widthwise frame member 10a from b to open and close in an X-shape.

On the other hand, among the two upper open ends 14 and 15 in the X-shape of the lift arm 6, the open end 13
The open end 14 on the side facing integrally with the rectangular frame 1 is pivotably supported on the open end 12 side within the rectangular frame 1 surrounded by the longitudinal member 2 and the reinforcing member 4. , the open end 15 on the side integrally facing the open end 12 is held slidably in the direction of the longitudinal member 2 within a frame surrounded by the longitudinal member 2 and the reinforcing member 4. This lift arm 6
It is formed to support the rectangular frame 1.

By this, by opening and closing the two lower open ends 12 and 13 of the lift arm 6, the rectangular frame 1 can be opened and closed.
Since the pivoted open ends 12 and 14 of the lift arm 6 are both on the same side, the rectangular frame 1 moves up and down with almost no deviation in the lateral direction with respect to the base 5. Then, the respective dimensions are set so that the lift arm 6 can be stored in the base 5 when the lower part of the lift arm 6 is opened to nearly 180 degrees or to 180 degrees.

Further, the lift arm 6 is opened and closed by a lifting device such as a hydraulic cylinder 16.

This hydraulic cylinder 16 is shown in FIGS.
As shown in FIG. 4, two thin hydraulic cylinders are used, and the base end of each hydraulic cylinder 16 is swingably attached to the inside of the open end 13 of the lift arm 6, and the tip of the cylinder rod 17 is It is swingably mounted slightly above the middle portion of the rectangular frame 7. Actually, the shaft portion of the fulcrum 9 of the rectangular frame 7 is covered with a mounting frame 18, and this mounting frame 18 is fixed to the rectangular frame 7, and the tip of the cylinder rod 17 is swingably mounted on the upper surface of this mounting frame 18. It is something.

Then, when the cylinder rod 17 of the hydraulic cylinder 16 pushes the middle part of the rectangular frame 7 slightly upward against the open end 13 of the rectangular frame 8, the angle between the open ends 13 and 15 is widened. Then, the lower open end 1 of the lift arm 6
2 and 13 move in the closing direction to raise the rectangular frame 1. Conversely, by pulling the cylinder rod 17 of the hydraulic cylinder 16 or by making the cylinder rod 17 easily retract into the hydraulic cylinder 16, the rectangular frame 1 is lowered by the pulling force or by its own weight. .

At this time, as the lift arm 6 expands in the horizontal direction, the lift arm 6 is housed within the base 5 and is surrounded by the longitudinal member 2 of the rectangular frame 1 and the two reinforcing members 4. The base 5 is housed within the frame. By doing so, the base 5 and lift arm 6 are completely housed within the rectangular frame 1, so at that point the overall height is only the height of each longitudinal member 2, 3 of the rectangular frame 1. Since the height of the frame is formed into an elongated rectangular frame that is wide enough to place the damaged vehicle and thick enough to be inserted under the damaged vehicle, the damaged vehicle itself is almost immovable. Despite this, the damaged vehicle can be easily placed, and in that case, the size of the hydraulic cylinder 16 is adjusted so that the hydraulic cylinder 16 is arranged so as not to protrude upward from the rectangular frame 1. ,
Or set the installation status.

On the other hand, a sliding roller 2 for sliding the base 5 in the longitudinal direction is provided at the open end 13 of the lift arm 6.
9 is provided, and in the direction of the open end 12,
A saw-shaped stopper 19 is provided.

This stopper 19, as shown in FIG.
One end of the elongated plate is swingably attached to the open end 13, and a plurality of locking notches 20 are formed on the lower surface to form the above-mentioned saw shape.

The longitudinal members 11a and 11b of the base 5
A locking protrusion 21 is provided on the inside of each of the
The inner wall on the widthwise frame member 10a side inside each locking notch 20 is formed vertically downward, and the locking protrusion 21 engages with the locking notch 20 of the stopper 19, thereby forming an X-shape of the lift arm 6. It is formed so as to prevent movement in the direction in which the shape becomes horizontally long, that is, movement of the open end 13 in the direction of the width direction frame member 10b.

Moreover, the inner wall on the widthwise frame member 10b side inside the locking notch 20 is formed to be inclined so as to expand downward, so that the X-shape of the lift arm 6 can be moved in the direction in which it becomes vertically elongated. When the open end 13 moves toward the widthwise frame member 10a, the stopper 19 is pushed toward the widthwise frame member 10a while the locking protrusion 21 is engaged with one of the locking notches 20. , the stopper 19 has the locking notch 2
0 is formed so that it is pushed and swung upward while being in contact with the locking protrusion 21. If the pushing continues, the locking protrusion 21 will be inserted into the next locking notch 20 again.
If this pushing motion continues, the locking protrusions 21 will sequentially engage with the plurality of locking notches 20 by repeating the above-mentioned rocking motion.

Also, in the process of engaging in this way, the open end 13
When there is a movement toward the width direction frame member 10b, if the locking protrusion 21 is engaged with the locking notch 20, the movement is blocked at that position as described above, and the stopper 19 swings upward. When the stopper 19 is moving, the locking protrusion 21 engages with the adjacent locking notch 20 due to the weight of the stopper 19, and movement is prevented at that position. That is, this stopper 19 functions as a ratchet by the locking notch 20 and the locking protrusion 21, and only prevents movement of the open end 13 in the widthwise direction of the frame member 10b.

When the rectangular frame 1 is lowered, the width direction frame member 10b of the open end 13 is moved by the stopper 19.
However, since it is dangerous to do so under or near the rectangular frame 1, it is made possible to do so by remote control in consideration of safety. .

That is, the longitudinal members 11a, 11 of the base 5
One stopper release cam 22 is provided outside the locking protrusion 21 on the inside of b, and the position of the stopper release cam 22 is set in the widthwise direction of the frame member with respect to the locking protrusion 21 at the interval between the locking notches 20. The location is close to 10a side. These stopper release cams 22 can be operated at a position away from the rectangular frame 1 by means of a cam operating bar 23, which is an elongated rod whose base end is bent at a right angle. As shown in FIG. 5, this stopper release cam 22 is approximately L-shaped and has one end rotatably attached to the longitudinal members 11a, 11.
The stopper release cam 22 can be rotated by passing the tip of the cam operation bar 23 through the shaft support portions of both stopper release cams 22 and rotating the right-angled portion of the base end. It is something that moves people.

When the locking protrusion 21 is engaged with the locking notch 20 of the stopper 19, the stopper release cam 22 is also in the adjacent locking notch 20. Therefore, the width direction frame member 1 of the open end 13 is fixed by the stopper 19.
To release the prevention of movement in the 0b direction, the stopper release cam 22 is rotated upward by the cam operation bar 23 to lift the stopper 19 upward.
By lifting the locking notch 20 and the locking protrusion 2
1 to release the movement prevention.

In this case, the remote control means does not have to be a rod-shaped device as described above, but may be performed by rotating the stopper release cam 22 using hydraulic, pneumatic, or electric methods, or the above-mentioned movement. The blocking may be released by retracting the locking protrusion 21, for example, instead of using the stopper release cam 22, and is not limited to this method.

Further, the rectangular frame 1 is lifted by the hydraulic cylinder 16 via the lift arm 6, and this hydraulic cylinder 16 is fed with high pressure oil through an oil pipe 25 from a hydraulic device 24 located at a remote location. It is designed to operate. The hydraulic system 24 can be operated from a remote location.
4, and even if it is near the lift device,
Or, it is designed so that it can be operated at any location even if you are far away.

Moreover, the longitudinal members 11a and 11b of the base 5
A guide protrusion 28 is provided on the inside of each of the guide protrusions 28 so that the open end 13 is slid in the direction of the longitudinal members 11a and 11b without being lifted upward. The shaft of the sliding roller 29 is engaged with the shaft. The base 5 is provided with width direction frame members 10a, 1.
A stabilizing plate 27 is provided to protrude laterally in the 0b direction,
It provides overall stability and serves as a mounting plate during installation.

On the other hand, a guide frame 30 is provided inside the longitudinal member 2 of the rectangular frame 1, and guides the open end 15 to slide in the direction of the longitudinal member 2. It serves to protect the open end 15 from mud, dirt, etc. that fall on the surface. Further, a protection frame 31 having the same shape as the guide frame 30 is provided at the position of the open end 14 to protect the open end 14 as described above.

It is formed into an elongated rectangular frame shape having a thickness, and a mounting groove 32 is formed on the side peripheral surface of the rectangular frame for mounting a measuring rod for damaged vehicles, a measuring member, a tensioning device for repairing, etc. , the lift device includes a base 5 that can be stored in an approximately middle portion of the rectangular frame, and an X-shape that can be stored within this base 5 and has two openings below it, with the approximately middle portion as a fulcrum 9. The ends 12 and 13 are held on the base 5 so as to be openable and closable, and the upper two open ends 1
4, 15 to support the rectangular frame 1 and lift it up and down, and a lifting device to lift the rectangular frame 1 by pressing the lift arm 6 in a direction where the X-shape becomes vertically elongated. Therefore, if the X-shape of the lift arm 6 is opened laterally, it will be stored in the rectangular frame 1 together with the base 5, so that the height at that time will be the height of the rectangular frame 1, and the height of the lift device will be A damaged vehicle can be easily placed on the rectangular frame 1 without digging into the floor of the installation location, and the lift device can be installed anywhere. Moreover,
Since the lift arm 6 has an X-shape, it can maintain a very stable state and can sufficiently withstand some uneven loads, and at the same time, the lift arm 6 can be stored compactly without taking up much space.

The lift arm 6 is provided with a stopper 1 that prevents the X-shape from moving in the horizontally elongated direction and that allows the release of this blocking by remote control.
9, it is very safe because the rectangular frame 1 will not fall unexpectedly even during or after the rectangular frame 1 is rising, and the stopper 19 can also be released by a remote device. So rectangular frame 1
