Description

[Detailed Description of the Invention] The present invention is a vehicle maintenance device, in particular, has at least two vehicle maintenance spaces, and performs each maintenance while moving a vehicle entered into one of the maintenance spaces in a direction perpendicular to the direction of entry. The present invention relates to a vehicle maintenance device used in a vehicle maintenance system that sequentially performs maintenance in a space.

Conventionally, two or more maintenance spaces are provided, and different types of vehicles are sequentially serviced in each space, thereby making vehicle maintenance an assembly line. In this case, a means of moving a vehicle that has entered one of the maintenance spaces in a direction perpendicular to the direction of entry (hereinafter referred to as lateral direction) is always required.

Therefore, as a means of transportation, a movable suspension lift was proposed (Japanese Patent Application Laid-open No. 107032/1983,
(Refer to Japanese Patent Application Laid-open No. 104442/1983) or one in which the trolley for boarding can be moved on a plane (Japanese Patent Laid-Open No. 57-104442)
(Refer to Publication No. 126747), and furthermore, a movable gate-type lift related to the application filed by the applicant (Utility Model Application No. 126747).
(see Japanese Utility Model Application Publication No. 188793, Japanese Utility Model Application Publication No. 57-195952, Japanese Utility Model Application Publication No. 58-16796, and Japanese Utility Model Application Publication No. 58-157757) have been developed and put into practical use.

However, whether it is a hanging lift or a gate-type lift, those that move the lift itself have the disadvantage of increasing the size of the entire device and increasing costs.Also, when moving a trolley on a plane, it is simply a horizontal movement between maintenance spaces. It was only used for transportation and was not suitable for vehicle inspection and maintenance, which required a lot of time to maintain the underside of the vehicle. In other words, in many vehicle maintenance procedures such as vehicle inspections, a lot of time is spent on maintenance of the underside of the vehicle, such as cleaning the undercarriage and lower part of the vehicle. is created.

The present invention focuses on the shortcomings of such conventional devices, and also aims to provide a vehicle maintenance device that can effectively utilize existing maintenance and devices. A pair of front and rear rails laid in a direction perpendicular to the entry direction, and at least a pair of left and right movable carts comprising a plurality of legs with wheels pivotally attached to the lower ends of which are foldably attached to the entry plate to run on the rails. and buried between the pair of front and rear rails in any of the vehicle spaces, supporting the entry plates for the pair of left and right movable carts,
The vehicle maintenance device comprises a buried type wrist that can be raised and lowered over a distance longer than the length of the leg.

An example of implementing the present invention will be described below with reference to the drawings.

Fig. 1 is a perspective view showing an embodiment of the vehicle maintenance device according to the present invention, and Fig. 2 is an explanatory diagram showing the installation state of the device in a plan view, where A is the first maintenance space and B is the first maintenance space. This is the second maintenance space. These various maintenance spaces are for convenience and do not necessarily have to be a separate maintenance room, but in the case of the illustrated embodiment, the second maintenance space also serves as a car wash room. The space is separated from the first maintenance space by a curtain 7 for preventing splashing of washing water.

A pair of cylinder lifts 1 are embedded in the first maintenance space A and are arranged at a predetermined interval in the lateral direction, and are configured to move up and down in conjunction with each other. In addition, a pair of front and rear rails 2, 2 are laid in the lateral direction at a predetermined interval in the first and second vehicle maintenance spaces A and B, so that a mobile trolley, which will be described later, can reciprocate between the two maintenance spaces. It's summery. Considering the access of vehicles, it is preferable to dig a rail groove in the floor surface of the maintenance space and bury the rail 2 in the rail groove. 3
This is a movable trolley that supports a vehicle entered from below, and is made up of a boarding plate 31 with four foldable legs 32 having wheels 33 pivotally attached to their lower ends. The width of the entry plate 31 is sufficient as long as the vehicle can enter the plate, so at least the width of the vehicle's tires is sufficient. However, in consideration of ease of entry and safety after lift-up, it is better to form it with some margin. . Also, the plate 31
Depending on the purpose of vehicle maintenance, the length may support the tires of the vehicle entered, or it may directly support the underside of the vehicle.In the former case, the length may be relatively long enough to support the front and rear wheels of the vehicle. In the latter case, it should be relatively short so that neither wheel can ride on it. However, considering the safety during lift-up, the versatility of being used for many types of vehicles, and the purpose of underbody maintenance, the latter, that is, a relatively short one, is preferable. Further, the lower surface of the plate 31 is preferably formed in a hollow state so that when the leg body 32 is folded, the leg body 32 can be contracted without protruding downward (for example, a side plate 31a is integrally provided). On the other hand, the leg body 32 is rotatably attached to the lower side of the entry plate 31 within a range of right angles in order to be foldable, and can be placed in an open state or a closed state (folded state).
In this case, the upper support rod 32a and the entry plate 3
A bendable support rod 3 diagonally connects the bottom surface of 1.
4, it is fixed in each state.

Reference numeral 4 denotes a connection mechanism rotatably attached to the lower side of the entry plate 31, which connects the entry plate 31 to the lifting plate 11 of the cylinder lift 1.
It is firmly fixed to the top surface of the That is, the connecting mechanism 4 connects the pair of locking members 41, 41 to the side plate 3.
The locking projecting plate 4 is pivotally connected between 1a and 31a.
1a and 41a are arranged to face inward from each other. Therefore, when the lifting plate 11 is in contact with the lower surface of the entry plate 31, the locking member 4
Both plates 11, 31 can be securely connected by rotating the plates 1, 41 inwardly and fixing them by suitable locking mechanisms. Various structures such as a pin or a locking mechanism can be considered as this locking mechanism, but in the case of the illustrated embodiment, a rectangular locking plate 42 is integrally attached to one end of the rotating shaft 41b of the locking member 41. , the shaft 41b is configured to be slidable in the axial direction, while the side plate 31a on one side
This is accomplished by drilling a locking hole 31b having the same shape as the locking plate 42 and fitting the locking plate 42 into the locking hole 31b. Furthermore, the elevating plate 11
In the connected state, the concave protrusion 32b attached to the middle of the leg 32 is fitted into the locking member 41b, so that the leg 32 can be folded so as not to be bulky. (See Fig. 3) A pair of movable carts 3 having the above configuration are placed on the rails 2, 2 on the left and right, and are configured to freely run on the rails 2, 2. .

On the other hand, an automatic lower cleaning device 5 is installed in the second maintenance space B. The automatic lower cleaning device 5
The lower main washing machine 52 reciprocates along the rail 51 laid in the direction parallel to the direction in which the vehicle enters, and sprays washing water from the injection nozzle 52a provided in the main washing machine 52. This device automatically cleans the underside of a vehicle, and its specific configuration is described in Japanese Utility Model Application Publication No. 128846/1983 and Japanese Utility Model Application Publication No. 51/1989.
Publication No. 145765, Publication No. 1965-96570, Publication No. 1965-96570, Publication No.
Since this is already known in Japanese Utility Model Publication No. 52-23875 and Japanese Utility Model Publication No. 55-26183, the explanation thereof will be omitted.

Next, FIGS. 4 and 5 show another embodiment of the present invention, and show a maintenance device in which three maintenance spaces can be secured.

That is, the maintenance space B in the first embodiment
A maintenance space C is provided at the other adjacent position, and rails 2 are laid in the same manner as described above to connect these three maintenance spaces A, B, and C.
A pair of mobile carts 3, which are the same as those in the above-mentioned embodiment, are further provided on the left and right, so that vehicles that have entered the maintenance spaces A and C can be alternately transported sideways to the maintenance space B, which serves as a car wash room. In this embodiment, in order to improve maintenance efficiency, another buried type lift 1 is provided in maintenance space C, but in some cases, a buried type lift may be provided only in maintenance space B, which serves as a car wash room. It's okay.

Next, FIGS. 6 and 7 show an embodiment in which the cross-feeding of the maintenance space C in the second embodiment is carried out by a conventional plane-feeding movable cart 6. According to the structure, when the vehicle is sent to the maintenance space B, it is lifted up, and when it is sent to the maintenance space C, it is sent to the maintenance space C in a flat state. Therefore, maintenance space C
It becomes possible to directly transport the vehicle from the

The movable trolleys 3 in each of the above-mentioned embodiments are designed to accommodate tires on one side of the vehicle, so they can be used simply by arranging the two trolleys 3, 3 in a pair on the left and right. The pair of movable carts may be connected by a connecting rod so that they can move together. Furthermore, as shown in FIG. 8, the connecting rod and the entry plate for the pair of movable carts are integrally formed, that is, maintenance openings 3 are provided in the middle on the left and right legs.
Even if a single plate 31' with a hollowed-out portion 1'c is placed thereon, the present invention has substantially the same function and effect as the one in which each of the movable carts 3 is separately provided. It is included in the technical scope.

On the other hand, considering the integrated access plate 31', it is sufficient to provide one unit in the center of the maintenance space, and if the vertical lift plate 11 is formed to be long in the horizontal direction, Even when a pair of left and right entry plates 31, 31 are provided, they can be raised and lowered at the same time.

Furthermore, the movable trolley 3 in each of the above embodiments is of a type in which movement of the trolley 3 relies entirely on manual labor in order to simplify the device and reduce costs; however, if such intentions are ignored, It is also possible to attach a drive mechanism to the cart, and by providing the drive mechanism, further labor savings can be achieved.

The present invention is constructed as described above, and how to use it will now be explained.

First, the buried type lift is lowered to its lowest point, and a pair of left and right movable carts with folded legs are placed on top of the lift at a predetermined distance. The rear vehicle rides on both entry plates of the movable trolley to a predetermined position, and the lift is raised to a position higher than the legs of the trolley to open the legs. Then, by gradually lowering the lift, the wheels ride on the rails, and the movable cart can move freely on the rails in a lifted state. On the other hand, to lower the vehicle to the floor, the procedure described above can be completely reversed. This idea is
Although it is used as described above, there is a specific maintenance system in which, for example, the vehicle is driven into the first maintenance space, the engine is serviced with the lift lowered, and then the lift is raised and sent to the second maintenance space. There, the lower part is cleaned and the undercarriage is maintained, and after these tasks are completed, the vehicle is returned to the first maintenance space, the lift is lowered, and the vehicle is taken outside. This can be carried out as appropriate depending on the worker, etc.

As is clear from the above explanation, since the present invention enables the vehicle to be moved laterally in the lifted up state, it is possible to develop a rational vehicle maintenance system according to the situation of each repair shop. Development is expected.

Furthermore, since the lift itself does not have a movable structure, the entire device can be simplified and manufacturing costs can be reduced, and existing buried type lifts can be used effectively, which is extremely effective.
