Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to an automobile engine cleaning device that automatically cleans the engine compartment of a maintenance vehicle during periodic inspection, maintenance, vehicle inspection and maintenance, etc. of the automobile.

``Prior Art'' Conventionally, this type of automobile engine cleaning device has been disclosed in Japanese Utility Model Application Publication No. 59-170054. A movable trolley that moves forward and backward into the engine room, two pipe members that swing left and right by a drive unit attached to the movable trolley, and a nozzle member that is integrally attached to the tip of the pipe member. It mainly consisted of

However, the above configuration had the following drawbacks.

Since there are a plurality of pipe members to which nozzle members are attached, when a nozzle with a cleaning effect is set, the amount of cleaning liquid to be supplied inevitably increases.

As a result, the size of the cleaning liquid pressure generating device and the like must be increased, resulting in high equipment costs.

In order to clean the engine room evenly, various drive devices are required that are capable of various operating modes, such as moving the movable cart forward and backward, swinging the pipe members, and rotating the nozzle. Therefore, in combination with the above-mentioned circumstances, the cleaning device itself becomes expensive.

Because the structure requires a large installation area, the work space becomes narrow. In addition, the cleaning equipment itself must be brought close to the engine compartment of the vehicle being serviced, so if workers are performing other inspection or maintenance work while cleaning, they must be able to move around the vehicle being serviced. It was not possible to pass through the pipes, which caused a negative effect on work efficiency.

Washing equipment is often used as a series of system car washing equipment, but in this case a device is required that allows the washing equipment to be brought close to the engine compartment of the vehicle being serviced when it is in place. Therefore, additional equipment costs are required when using this cleaning device.

``Problems to be solved by the present invention'' In view of the above-mentioned drawbacks of the conventional technology, the present invention can be manufactured at low cost by reducing the number of parts, requires less installation space, and Even if installed in the engine room, it will not interfere with other inspection and maintenance work, and the entire engine compartment can be cleaned evenly. There is no need to run the car engine cleaning equipment.

A small-diameter fourth sprocket is fixed so that it can rotate simultaneously with the upper pivot, and a chain 17 is wound between the third and fourth sprockets. Reference numeral 8 denotes an opening/closing arm that gradually opens as the tilting arm 7 falls toward the engine compartment D of the automobile C, as described above, and in this embodiment, one opening/closing arm is positioned between the left and right tilting arms 7a and 7b. the upper end of which is connected to the upper axis 1
It is fixedly provided in the center of 0. Reference numeral 18 denotes a long box-shaped injection nozzle support member which is attached horizontally to the lower end or lower end of the opening/closing arm 8, and one or two injection nozzles 19 are installed at the tip of this injection nozzle support member 18. In the example, two projecting from the left and right side walls of the injection nozzle support member 18, respectively, are provided downward. Reference numeral 20 denotes a support arm that supports the injection nozzle support member 18 so that it can be kept in a horizontal state at all times.
The upper end of the opening/closing arm 8 is pivoted to a pair of upper pivot plates 21 on the left and right, which are provided in a free state from the upper pivot 10 so as to narrow the upper end of the opening/closing arm 8, and the lower end of the opening/closing arm 8 is The nozzle support member 18 is pivotally supported by a lower pivot plate 22 that is integrally provided at the rear end of the nozzle support member 18, and the support arm 20 and the opening/closing arm 8 are connected to each other via upper and lower pivot plates 21 and 22 in the shape of a square quadrilateral.

Reference numeral 23 denotes an air nozzle provided somewhat closer to the tip side than the injection nozzle 19, and this air nozzle 23 is connected via a hose 24 to an air pressure source (not shown).

In the above configuration, when the engine washing device X is used as a series of system car washing devices, it is set at a position somewhat distant from the bumper of the automobile C to be serviced or washed, as shown in FIG. In this case, it is desirable to provide a space that allows a worker to easily pass between the vehicle C and the engine car wash device X when the worker desires to perform inspection and maintenance work other than cleaning at the same time. When the preparations are completed as shown in FIG. 1, a switch (not shown) of the second drive device 5 is turned on, and the second drive motor 5a is driven. This driving force is reduced by the reducer 5b,
The protruding shaft 9 rotates clockwise as shown in FIG. Then, since the left side tilting arm 7a is integral with the protruding shaft 9 and is connected to the right side tilting arm 7b by the connecting pin 11, the tilting arm 7 rotates simultaneously with the protruding shaft, and from the vertical state as shown in FIG. The injection nozzle 19 is tilted to the position indicated by the imaginary line indicated by , that is, to the point where the injection nozzle 19 almost enters the engine room D of the automobile C. At this time, the opening/closing arm 8 has the third sprocket 15 fixed to the reducer 5b and the fourth sprocket 16 fixed to the upper pivot 10, so as the tilting arm 7 is tilted toward the engine room D, the upper pivot 10 is fixed. Since it rotates in the opposite direction to the protruding shaft 9 of the reducer 5b, it opens as shown. Next, at a point on the line a shown in FIG. 3, specifically, when the injection nozzle 19 is located at the front of the engine room D, the first drive device 3 is switched on and the first drive motor 3a is turned on. to drive. This driving force is the chain 3c
is transmitted to the vertical rotation 3b, and the upper support base 4 swings its head from side to side. As a result, the tilting arm 7 gradually falls down, and the opening/closing arm 8 gradually opens while swinging the injection nozzle support member 18 from side to side. By the way, if the swing angle or fan angle of the opening/closing arm 8 from side to side remains constant throughout, as the tilting arm 7 falls forward and the opening/closing arm 8 opens, the cleaning range will be expanded laterally. The cleaning water injected from the injection nozzle 19 ends up scattering outside the engine room D. Therefore, as shown in FIG. 3, the injection nozzle support member 18 is
Even when it is located in the deep part c, it is desirable that it does not protrude outward from above the left and right partition lines A and B that should be the cleaning range of the engine room D. In order to solve this problem, the present invention detects the inclination angle or the inclination time of the tilting arm 7 on the protruding shaft 9 of the reducer 5b to support the fan-shaped angle or upper part of the opening/closing arm 8. An opening/closing arm sector angle control device that can control the swing angle of the table 4 is provided. Therefore, in this case, the fan-shaped angle of the opening/closing arm 8 becomes smaller as it opens from the front part a to the rear part c of the engine room D, and corresponds to the opening of the engine room D as shown in FIG. Cleaning is performed in a square or rectangular shape. FIG. 8 shows a case where the tilting arm 7 is tilted to the maximum extent, and the opening/closing arm 8 is also opened to the maximum extent and both are in a straight line. In this state, the second
The drive motor 5a rotates in the opposite direction, and the opening/closing arm 8 and the tilting arm 7 return to their original states shown by solid lines in FIG. 1 while cleaning continues.

Next, different embodiments of this embodiment shown in FIGS. 9 to 11 will be explained. In the description of this embodiment, the same parts as in the embodiment of the present invention will be denoted by the same reference numerals and redundant explanation will be omitted.

The embodiment shown in Figs. 9 to 11 is different from the embodiment of the present invention in that a spray nozzle swinging device 30 is added. This spray nozzle swinging device 30 is composed of a third drive motor 31 attached to the top end of the hollow opening/closing arm 8A, and a sprocket 32 provided on the output shaft of the third drive motor 31.
and a chain 35 wound between a sprocket 34 provided on the pivot shaft 33 of the lower pivot plate 22A.
and a power conversion mechanism 36 which converts the driving force of the drive motor 31 transmitted by the chain 35 into crank motion.

In this embodiment, the injection nozzle swing device 30
Since the injection nozzle 19A swings back and forth, there are advantages such as fewer blind spots during cleaning.

In addition, in the embodiment of the present invention, it was stated that it is a preferable embodiment to control the sector angle of the opening/closing arm 8, but at the same time, the angular velocity of the opening/closing arm 8 that moves in a sector shape is also controlled, so that the fan-shaped arc-shaped velocity is always maintained. It is also possible to make them the same.

"Effects of the Present Invention" As is clear from the above explanation, the present invention has the following effects.

(1) Compared to conventional engine cleaning devices of this type, the number of parts is reduced, so it can be manufactured compactly and at low cost.

(2) Especially in the case of an embodiment with one opening/closing arm and one or two injection nozzles provided on the injection nozzle support member, there is no need to increase the size of the cleaning liquid pressure generator, etc., so equipment costs can be reduced. can do.

(3) Since the tilting arm and the opening/closing arm are combined, the engine washing device can be installed in front of the car being serviced or washed with a space large enough for a worker to pass through.

Therefore, it is possible to improve work efficiency.

(4) While the tilting arm is falling down, the opening/closing arm is moved in a fan-like manner by the first drive device of the lower support base, so the injection nozzle does not move away from the engine room.
Furthermore, the cleaning range can be expanded. Particularly in the case of an embodiment in which an opening/closing arm sector angle control device is provided, cleaning can be performed corresponding to the opening of the engine room, so that the cleaning liquid does not scatter.

(5) It is compact overall, so it does not take up a large installation area.

(6) Even when used as a series of cleaning devices, the engine cleaning device of the present invention does not need to be placed directly in front of the automobile, so no extra equipment is required.

(7) In the embodiment in which the injection nozzle swings, blind spots during cleaning are reduced, so that the engine compartment can be cleaned evenly.

(8) Other operations are easy.
