2. Description of the Related Art Inspection and maintenance of a brake cylinder is often performed when an automobile is inspected and maintained. In particular, in vehicle inspection (vehicle inspection), disassembly and maintenance of the master cylinder in the brake cylinder is an essential work item. At this time, after the brake fluid is removed from the reservoir tank by a suction pump as much as possible, the master cylinder is disassembled, and each part is cleaned using an air blow gun. The air cleaner element is also cleaned by blowing off the attached dust with compressed air from an air blow gun.

[0003]

However, even if the brake fluid is suctioned and removed from the reservoir tank as described above, the brake fluid still remains in the master cylinder. When the master cylinder is disassembled, the remaining fluid is removed. Runs around. Furthermore, since the components of the disassembled master cylinder are cleaned by blowing compressed air with an air gun, the surroundings are also contaminated by blown fluid or dust. For this reason, there is a problem that the periphery must be cleaned after the work is completed, and the tool and the operator themselves are also stained by fluid, dust, and the like. A similar problem has occurred in the disassembly and cleaning of the air cleaner element. In view of the above, the present invention is to provide a clean worktable that can perform disassembly and cleaning work of a master cylinder, an air cleaner element, and the like of a brake without polluting the surroundings.

[0004]

Therefore, in order to solve the above-mentioned problems, the present invention provides a workbench for a vehicle mechanic to perform an operation for repairing a vehicle part by inserting an arm. A wall surrounding the working space except for an opening through which the worker inserts an arm, and a pipe arranged along the upper edge of the wall and allowing water to flow down from a row of small holes provided on the way. Thus, a vehicle component maintenance table including a suction duct communicating with the work space and a motor connected to the suction duct and suctioning air in the work space is created.

[0005]

According to the vehicle component maintenance table of the present invention having the above-described structure, first, the parts to be cleaned are placed in the work space on the work table. Then, the worker's arm is inserted from the opening, and the parts and the like placed in the working space are disassembled,
Cleaning is performed using an air blow gun or the like. Here, the working space is surrounded by a wall except for the opening into which the worker's arm is inserted, so that dirt and dust generated during disassembly and cleaning do not scatter to the surroundings. Stay in.

[0006] Then, water flows down from a row of small holes provided in the middle of a pipe arranged along the upper edge of the wall, whereby a film-like water flow is formed along the wall surface and the floor surface. As a result, fluid, dust and the like that have fallen on the floor or scattered toward the wall are washed away by the water current and do not adhere to the floor or the wall. Further, since a suction duct communicating with the work space and a motor connected to the suction duct and sucking the air in the work space are provided, dust and the like flying in the work space are removed by the suction duct. It is sucked and discharged. In this way, all dirt such as fluid and dust that have come out of the working space of the vehicle parts maintenance table is removed without scattering to the outside or adhering to the surroundings. Thereby, the disassembly and cleaning work of the master cylinder and the like is performed without polluting the surroundings.

[0007]

[Effect of the Invention] In the present invention, since a vehicle parts maintenance table is created in which water flows along the wall surface and bottom surface surrounding the work space and vacuum suction is performed, fluid, dust, etc. generated in the work space are reduced. , Are all removed without scattering or adhering to the surroundings. This makes it possible to perform the disassembly and cleaning work without soiling the workplace and the workers, and a clean and comfortable work environment is maintained.

Next, the water absorbing polymer measuring device D30 will be described with reference to FIG. The water-absorbing polymer measuring device D30 is a device for measuring the amount of the water-absorbing polymer necessary for solidifying the old cooling water and putting it into the drainage tank D22. At the bottom of the water-absorbing polymer tank D31 for storing the powdery water-absorbing polymer described above, a slit-shaped falling port D34 is provided, and a slit having a shape corresponding to this is also provided on the opening / closing plate D33. . When the opening / closing plate D33 slides with respect to the drop port D34, a drop port opening of an arbitrary size is obtained depending on how the slits overlap. The opening / closing plate D33 is connected to the closing lever D32 by a first joint D37. When the closing lever D32 is moved up and down, the opening / closing plate D33 slides.
Further, a second joint D3 is provided at the tip of the closing lever D32.
8 are connected. The second joint D38 is connected to the input port plate D36, and the input port plate D36 is moved up and down by moving the input lever D32 up and down.
Open and close to 35.

Normally, since the closing lever D32 is at the upper end position, the opening / closing plate D33 is in the fully open state and the opening port plate D36 is in the fully closed state. Therefore, the water-absorbing polymer in the water-absorbing polymer tank D31 is stored in the opening / closing plate D33.
, And falls into the weighing case D39. When the closing lever D32 is pressed down from this state, the opening / closing plate D33 is fully closed, and the closing port plate D
36 is fully opened, and a predetermined amount of the water-absorbing polymer in the measuring case D39 is charged into the drainage tank D22. Thereafter, when the charging lever D32 is pulled up and returned to the upper end position, the new water-absorbing polymer passes through the slit of the opening / closing plate D33 and fills the measuring case D39, and is ready for the next charging.

Now, a method of exchanging cooling water using the cooling water exchanging wagon D having the above configuration will be described with reference to FIGS. First, a cooling water pipe connected from the engine room side to the heater side indicated by 100 in FIG. 14 is separated on the way. That is, the rubber tube connecting the pipe on the engine room side and the pipe on the heater side is removed from the clamp holding the rubber tube by a tool provided in the wagon D, and the portion 100 in FIG. Remove from Subsequently, the tip of the water hose S shown in FIG. 1 is pulled down from the ceiling and connected to the injection pipe D46 shown in FIG. Further, this injection pipe D46 is connected to the port of the rubber tube separated earlier, and the port 100 on the side connected to one engine room is closed by fitting a rubber plug D43 for injection. In this way, the tap water flows only to the heater (not shown) in FIG. On the other hand, a cooling water discharge hose D42 is attached to the radiator cap 103 via a discharge adapter D45 and a discharge pipe D44. In addition, the separated mouth 100 on the engine room side
Is located at the highest position of the engine cooling water circulation path, and even if tap water is supplied from the cutout on the heater side, it overflows from the radiator cap 103 first, so that it is not always necessary to close it with the cap.

In this state, tap water is supplied from the tap hose S, and tap water is fed from the portion 100 in FIG. 14 toward the heater. Tap water is split into two parts at 106 parts shown in the figure via a heater not shown, passes through 101 parts and 104 parts, and is discharged from 103 parts. The old cooling water discharged is
The drainage tank D2 of the wagon D passes through the cooling water discharge hose D42 from the discharge adapter D45 and the discharge pipe D44.
Flow into 2. In addition, the illustration 105 is a radiator fan. At this time, the fact that the old cooling water has been completely replaced with the new tap water is determined by observing the color of the discharged water through the transparent discharge pipe D44. The old cooling water has red or green colored L
This determination can be easily made because LC is mixed.

After confirming that the tap water was completely replaced with new tap water, the supply of tap water from the tap hose S was stopped, and the injection pipe D46 was removed from the tip of the tap hose S, and LL
Connect to C injection tank D50 to inject LLC. LL
The injection port D55 of the C injection tank D50 has a funnel shape as shown in the sectional view of FIG. 15, and can be extended upward by the elastic joints D52 and D53. The LLC can be injected into the engine quickly and reliably due to the height difference. LLC injected at this time
Of the cooling water is discharged from the drain port 101.

On the other hand, the old cooling water received in the drainage tank D22 is replaced with a water-absorbing polymer measuring device D30.
The water-absorbing polymer is charged and solidified. By supplying a predetermined amount of the water-absorbing polymer in this manner, the old cooling water in the drainage tank D22 becomes a solid state. In addition, since the water-absorbing polymer is mainly composed of alcohol, the old solidified cooling water becomes flammable. Therefore, the old cooling water in the solid state is thereafter extracted from the drainage tank D22 and incinerated by the wastewater incineration equipment. Thus, the replacement work of the engine cooling water and the LLC (long life coolant) is completed.

As described above, by using the cooling water exchange wagon D, the cooling water exchange operation can be performed comfortably without polluting the work place, and the air in the cooling water passage is completely vented. Furthermore, by providing a wagon function, the mobility is greatly improved, and the work is facilitated. In addition, since the necessary parts are combined in one wagon, the effect of replacing the cooling water in a short time can be obtained. Not only that, the old cooling water becomes solid, so that it can be easily treated, and the trouble of flowing to general wastewater to cause water pollution can be prevented beforehand.

It is connected to the brake fluid supply / discharge facility M. Then, by turning on the pump power switch M40 previously described in the section (3F), the discharge pump M24 of the supply / discharge facility M operates, and the used brake fluid is discharged from the end of the discharge drawer hose U20. It can be sucked and discharged through the brake fluid discharge hose U. Here, only the fluid in the reservoir tank is removed prior to disassembly and maintenance of the master cylinder, and the fluid still remains in the master cylinder. Therefore, when the master cylinder is disassembled, the remaining fluid overflows and pollutes the surroundings. In order to prevent this, a clean work table (vehicle parts maintenance table) H shown in FIGS. 17 and 18 is provided.

As shown in FIG. 17, the framework of the clean workbench H includes a floor plate H1 on a workbench base H50.

Lower the discharge hose U20 to near the floor of the workplace. Then, the distal end of the discharge hose U20 is inserted into the reservoir tank from above the brake cylinder of the vehicle, and the fluid in the reservoir tank is sucked and discharged. When the discharge of the fluid from the reservoir tank is completed, the operator next carries the brake cylinder to the clean work table H, and fixes it to the vise H40.

Then, the master cylinder is disassembled, and the inside is cleaned by the air blow gun H28. At this time, the sensor switch of the air gun holder H24 operates, and the water flowing mechanism and the suction mechanism are automatically activated as described above to wash away the remaining fluid in the master cylinder, dust blown off by the air gun, and the like. The dust generated inside is sucked from the suction duct H37. When the air blow gun H28 is returned to the air gun holder H24, the flowing water and the suction are automatically stopped. Thus, the overhaul work of the master cylinder is performed in the work space H1.

As described above, the water flows along the three wall surfaces and the bottom surface of the working space H1, and the vacuum suction is performed at the same time, thereby preventing the brake fluid, dust, dust and the like from adhering and scattering. The workplace can be kept clean. After the disassembly and cleaning of the master cylinder, the inspection, and the replacement of worn parts are completed, the master cylinder is assembled again and assembled to the vehicle. Thereafter, as described above, the brake inspection work is performed by the brake inspection wagon B. The cleaning operation of the air cleaner element is also performed in the clean work table H. Also in this operation, it is possible to prevent dust and the like adhering to the element from scattering into the work place due to the effect of flowing water and suction.
