(1) Overall overview of vehicle maintenance equipment The vehicle maintenance equipment according to this embodiment has a uniform design so that vehicle maintenance work such as vehicle inspection can be carried out efficiently and easily in a good and clean environment. It was newly developed based on this idea. FIG. 1 schematically shows the overall configuration of this device. This device has the following features.

[0013]B. Tools, measuring instruments, and other equipment necessary for vehicle maintenance are categorized by major work and stored in each work wagon. For example, A in the figure is a wagon that accommodates all the equipment necessary for exchanging lubricating oil such as engine oil, and by using this wagon A, exchanging lubricating oil can be carried out. Similarly, Wagon B houses the tools necessary for brake inspection work, Wagon C houses the tools, measuring instruments, and other equipment necessary for inspecting the engine compartment, and Wagon D houses the equipment necessary for replacing coolant. has been done. The worker can carry out maintenance work with the wagon necessary for the work at hand, and the worker does not have to spend time searching for the necessary equipment.

B. Each wagon simultaneously houses equipment classified in relation to vehicle location. For example, work that involves lifting a vehicle to the highest position and requiring a worker to crawl under the vehicle is done entirely using Wagon A, and work that is performed when the vehicle is at an intermediate height is performed using Wagon B. All are now being carried out using the .

C. Wagons are usually housed in wagon storage units to ensure that the work environment remains tidy and tidy. FIG. 1 illustrates a state in which an oil change wagon A is used. D. Preparation for the next maintenance operation is automatically carried out while the wagon is stored in the wagon storage unit. For example, the oil change wagon A is provided with a tank for collecting waste oil and a new oil tank for storing new oil. These tank capacities are limited. When this wagon A is housed in the housing unit E, the wagon A and the housing unit E are connected by a connector, and the waste oil is discharged from the waste oil tank and new oil is supplied to the new oil tank. Therefore, the next time wagon A is used, the waste oil tank will be empty and the new oil tank will be stocked with new oil, allowing the next operation to be carried out immediately.

[0016] E. A washing facility J and a clean workbench H are installed in the accommodation unit, and consideration has been given to keeping the working environment clean. F. What used to be a two person job can now be done by one person. For example, the brake inspection wagon B is provided with a switch for pressurizing or not pressurizing the brake fluid, so that one person can bleed air from the brake fluid.

[0017] G. Oil, cooling water, etc. are not discharged onto the floor.
We are making sure that everything is collected. This maintains a good working environment and eliminates drainage problems. blood. A spot unit incorporating a cooler, heater, and lighting equipment is installed so that it can be moved around the vehicle. This allows workers to work comfortably in a good environment.

[0018] Li. Electricity, signals, compressed air, etc. for operating power tools, pumps, etc. housed in each wagon are connected via cables and hoses from the cart on the ceiling, so the cables and hoses do not crawl across the floor. This is taken into consideration. Nu. Each wagon is connected to a power source, and when a particular wagon is connected, all of the power tools stored in that wagon, that is, all of the power tools necessary for each work, become ready to be driven. . For example, brake inspection wagon B
Once connected, all of the air impact wrenches, air ratchet wrenches, tire gauges, air guns, etc. necessary for brake inspection work are ready for use. Therefore, there is no need to replace the connector each time you work.

[0019] Le. Exhaust gas equipment is always stored in the ceiling, ensuring a wide working space. Wow. When the exhaust gas hose and exhaust gas analyzer of the exhaust gas equipment are lowered, the exhaust gas hose is lowered a distance that allows it to be connected to the vehicle's exhaust pipe, while the exhaust gas analyzer is lowered only to the worker's eye level, making it difficult to carry out the work. It is designed to be easy to use. W. Lighting equipment X is embedded in the floor, and when the vehicle is lifted with lift V, lighting equipment X is automatically turned on. Therefore, the operator can work with the bottom of the vehicle illuminated.

Next, each part will be explained in detail. (2) Systemized Wagon (2A) Oil Exchange Wagon Referring to FIGS. 2 to 5, an oil exchange wagon A and a storage unit E for accommodating it will be described. Figure 2
3 is a perspective view of wagon A viewed from approximately the left side, FIG. 3 is a perspective view of wagon A viewed approximately from the right side, FIG. 4 is a rear view, and FIG. 5 is a view of accommodation unit E viewed from the front with wagon A removed. It shows. In Fig. 2, A1 is a connector for connecting to an air hose hanging from the ceiling, and when compressed air is supplied here, the hose is connected to an air impact wrench A17 and an air ratchet wrench, whose hoses are shown in Fig. 3. A1
Compressed air is supplied to the air pump A10 shown in the lower part of FIG. Air impact wrench A17 and air ratchet wrench A18 are power tools required for lubricating oil replacement work, and since both are connected to compressed air, there is no need to change tools for the air hose during lubricating oil replacement work. do not have.

In FIGS. 3 and 4, A20 is a suction port, and a suction hose A1 wound around a drum is connected to the suction port.
Connected to 2. The other end of the suction hose A12 is connected to the suction port of the pump A8 via a first switching valve (not shown), and the discharge end of the pump A8 is connected to a second switching valve (not shown).
It is connected to waste oil tank A25 via a switching valve. This suction port A20 is pulled out from the drum and inserted into the insertion port of the engine oil gauge of the engine. A26 shown in FIG. 3 is a new oil tank, and A23 is an engine oil tank. New oil tank A26 and oil tank A
A suction port A28 inserted into the intake port A23 is connected to the first switching valve via a third switching valve. A switch is provided on the top of the wagon, and the new oil tank A is connected to the first switching valve.
26 or the suction port A28 for the oil tank A23 can be switched. Further, the discharge side of this pump A8 is connected to a supply hose A11 wound around a drum via the second switching valve,
A supply port A19 is attached to the tip of this supply hose A11. This supply port A19 is inserted into the engine oil supply port of the engine.

Weight sensors A30 and A23 are installed at the bottom of the waste oil tank A25, new oil tank A26, and oil container A23, respectively.

Controls the switching valve. This microcomputer and pump A8 are connected to connector A2. Connector A2 is connected to a power cable hanging from the ceiling.

[0023] Suction port A20 and supply port A1
When the start switch on the top of Wagon A is pressed with each of the 9 set in the engine, waste engine oil is first sucked from the suction port A20 by the first and second switching valves and sent to the waste oil tank A25. Pump A8 is then driven. At the same time, the signal from the weight sensor A30 below the waste oil tank A25 is input to the microcomputer at predetermined time intervals. When the microcomputer determines that the signal from the weight sensor A30 does not change for a predetermined period of time or more, the pump A8 is stopped. Here, the signal difference between when the pump A8 starts operating and when it stops is compared, and if the difference is less than a predetermined amount, the lamp A13 is turned on to notify the operator that the engine oil is insufficient.

After that, the first and second switching valves are switched so that new oil is sucked from either the new oil tank A26 or the engine oil tank A23 selected by the third switching valve and sent to the supply port A19. Pump A8 is driven again. At this time as well, weight sensor A29 or A3
1 signals are input to the microcomputer one after another, and when the difference between the signals at the start of operation and the time when the pump A8 starts and stops, the pump A8 is stopped. In other words, the same amount of new engine oil as the sucked-in waste engine oil is sent to the engine. Here engine oil kan A2
3 is used when the vehicle owner specifies the brand of engine oil, and this oil tank is set and the third switching valve is switched using the switch mentioned above to specify the state in which the oil is sucked from this oil tank. The specified engine oil is then supplied to the engine.

All operations up to this point are performed automatically, and the operator can carry out other work while changing the oil. When the worker finishes the other work, if the lamp A13 is not lit, he knows that the oil change has been completed successfully, and removes the suction port A20 and supply port A19 from the engine, and restores the initial state (see Figures 3 and 4). state). A14 in Figure 3
is lit when there is no engine oil in the new oil tank A26, and A15 is lit when the waste oil tank A25 is full of waste oil. As will be described later, the present wagon A and accommodation unit E are designed to prevent such a situation from occurring, but if an abnormality occurs for some reason, it can be known by lighting the lamps A14 and A15.

A16 in FIG. 3 is a hand tool used for oil change work and for lifting the vehicle upward and inspecting the bottom surface of the vehicle. It has become. That is, all the equipment necessary for inspection and maintenance work performed on the bottom surface of the vehicle by an operator after lifting the vehicle to a high position is housed in this oil change wagon A. In other words, the oil change wagon A is also a wagon for high-position work.

In FIG. 2, A4 is a funnel for receiving waste oil when removing gear oil from the drain of the differential device or transmission with the vehicle raised to a high position, and the received waste oil is collected in the waste oil tank A25. Ru. In addition, A6 in the figure is a gear oil box storage area, and the suction port A5 is inserted into this box, and the air pump A1
When 0 is activated, gear oil is sucked out from the oil tank and discharged from gun A3. Workers can use this to change gear oil. Note that the gun A3 can be pulled out by a hose wound around the drum A7.

In FIG. 4, A21 is a waste oil recovery connector connected to a waste oil tank A25 via a pump A8. A22 is connected to new oil tank A via pump A8.
This is the new oil supply connector connected to 26. A27 in the figure is a connector for transmitting a power supply to the pump A8, the first to third switching valves, the microcomputer, and signals from the microcomputer to the housing unit E. These are the mating connectors E21, E22 and E when the wagon A is accommodated in the accommodation unit E shown in FIG.
27.

In this state, the pump A8 pumps up waste oil from the waste oil tank A25 and sends it to the connector E21. The sent out waste oil is stored in a large waste oil tank (not shown). When the weight sensor A30 detects that the waste oil tank A25 is empty, the pump A8 is temporarily stopped. After that, pump A8 sucks new engine oil from connector E22 and supplies the new oil to tank A26. Note that a large new oil tank is installed on the back side of connector E22. When it is determined from the weight sensor A29 that a specified amount of new oil has been sent to the new oil tank A26, the pump A
8 is stopped. Here, when pump A8 is operating, lamp E
3 lights up, and when pump A8 stops operating, lamp E3 lights up.
goes out. Since the lamp E3 is off, the operator can know that the next oil change operation is now possible. Note that E4 in the figure is an abnormality display lamp that lights up in the event of some abnormality.

[0030] By using the present wagon A and storage unit E, the operator can change the oil unattended to a large extent without getting his hands dirty, and the oil change work becomes more efficient and clean.

(2B) Brake Inspection Wagon A brake inspection wagon B is shown in perspective view in FIGS. 6 and 7. This wagon B is normally housed in a housing unit F shown in FIG. 1, and during brake inspection work it is pulled out from this housing unit F and transported to a working position around the vehicle. The wagon B includes an air connector B2 and a power connector B4. By connecting the air hose O5 extending downward from the trolley O4 of the ceiling equipment shown in Fig. 1 to this air connector B2, various air-driven tools necessary for brake inspection work and this wagon B can be connected. All the air cylinders B36 of the tire lifter B30 provided can be used.

On the other hand, an electric cable O3 extending downward from the trolley O4 of the ceiling equipment is connected to the power connector B4 together with the air hose O5. Wagon B again
is provided with a switch B6. This switch B6
By connecting the electric cable O3 to the power supply connector B4, the solenoid valve of the brake fluid supply and discharge equipment M in the unit shown in FIG. 1 can be opened and closed by remote control. The electromagnetic valve is incorporated into the discharge path of the fluid supply pump in the brake fluid supply and discharge equipment M, as will be described in detail later. This discharge passage leads to a brake fluid supply hose T20 hanging from the ceiling in FIG. 1. Therefore, by controlling the opening and closing of the electric solenoid valve by remote control of the switch B6, it is possible to supply brake fluid at a predetermined pressure from the brake fluid supply hose T20 or to stop it.

[0033] The wagon B is equipped with a tool case B8. In addition to the air-driven tools (impact wrench, ratchet wrench, tire air pressure gauge, etc.), various hand tools (hammer, screwdriver, etc.) necessary for brake inspection work are stored in the tool case B8. Furthermore, the wagon B is equipped with a transparent tube B12 connectable to the bleeder plug of the brake wheel cylinder and a fluid receiver B14. The old brake fluid collected in this tube B12 and fluid receiving tray B14 is stored in a waste oil tank B that is removably installed on the wagon B.
collected in 10.

When inspecting the brakes and replacing the brake fluid using the wagon B, the vehicle is lifted up to an intermediate height. Here, the air hose O5 is connected to the air connector B2 of the wagon B, and the electric cable O3 is connected to the power connector B4. Then, use the air-driven tool in the tool compartment B8 to loosen the tire hub nut and remove the tire. Perform various inspection work in this state.

When exchanging the brake fluid and removing air, the brake fluid supply hose T20 shown in FIG. 1 is connected to the reservoir tank of the brake master cylinder located in the engine room. Further, the tube B12 of wagon B is connected to the bleeder plug of the brake wheel cylinder. When this preparation is completed, loosen the bleeder plug and switch B.
6 to open the solenoid valve of the brake fluid supply and discharge equipment M. As a result, new brake fluid is supplied from the fluid supply pump of the brake fluid supply and discharge equipment M to the reservoir tank of the brake master cylinder through the brake fluid supply hose T20, and the fluid is replaced or replenished. Note that when disassembling the brake wheel cylinder, the fluid receiving tray B14 is placed under the hub to receive dripping fluid, which is collected in the waste oil tank B10. At this time, in order to reduce the pressure of new brake fluid, the switch B6 is
Close the solenoid valve by operating.

When bleeding air from the fluid in the brake hydraulic system, the switch B6 is turned on and off to repeatedly supply and stop fluid to the reservoir tank of the brake master cylinder. As a result, the fluid in the brake hydraulic system is repeatedly pressurized, and with this pressurization, the transparent tube B1 is inserted from the bleeder plug.
Fluid mixed with air bubbles will come out. Once the air bubbles disappear, tighten the bleeder plug to finish bleeding the air. After this, attach the tire to the hub and tighten the hub nut. All brake-related maintenance work is completed by performing the above tire removal, brake inspection, fluid replacement, air bleed, and tire installation at each wheel location, and going around the vehicle. During this time, the air hose O5 and the electric cable O3 remain connected to the air connector B2 and power connector B4 of the wagon B, respectively, and there is no need to attach or detach the connectors each time the wagon B is moved.

Next, the tire lifter B30 installed in the brake inspection wagon B will be explained. As already mentioned, brake inspection work requires tire removal work. Therefore, a tire lifter B30 is installed on the back of Wagon B. The tire lifter B30 includes a pair of columns B32 fixed to the left and right sides of the back of the wagon B, and a lifter B34 is provided so as to be movable up and down along the columns B32. The lifter B34 moves up and down by the operation of the air cylinder B36, which is driven by air supplied through the air hose O5 connected to the air connector B2 of the wagon B. Note that switching the air supply to the air cylinder B36 or stopping it is performed by operating a switch B38 provided on the wagon B.

[0038] The lifter B34 includes a fork B40.
is attached so as to be rotatable to the storage state shown in FIG. 6 or the state in which a tire can be placed as shown in FIG. A tire support frame B42 is foldably attached to the fork B40 to support the tire mounted thereon so that it does not fall. Furthermore, the fork B40 has a roller-like structure with a pipe covering the outer periphery of the shaft, allowing the tires placed there to rotate smoothly.

Now, when removing a tire using the tire lifter B30, the wagon B is positioned below the tire of the vehicle that has been lifted to an intermediate height during the brake inspection work described above. Then, operate the switch B38 to lift the fork B40 together with the lifter B34.
, and this fork B40 supports the tire from below. If the hub nut is removed from the hub bolt and the tire is removed from the hub side, the tire will be placed on the fork B40. If this continues, the tires will become an obstacle to the brake inspection work, so the fork B40 is lowered by operating the switch B38, and the tires are positioned on the back of the wagon B.

When the brake inspection work is completed, switch B38 is operated again to raise the fork B40 and tire to a height where they can be easily attached to the hub side. Fork B here
Finely adjust the height of 40 to match the height of the hub bolt and the tire bolt hole. Further, the circumferential misalignment between the hub bolt and the bolt hole is corrected by rotating the tire on the fork B40. After this adjustment, the tire is assembled by pressing it against the hub using the movement of wagon B, and the hub nut is tightened to complete the tire installation and removal. Note that when storing the wagon B in its storage unit F, the fork B40 is folded as shown in FIG.

(2C) Engine Room Inspection Wagon The engine room inspection wagon C and the storage unit G for accommodating it will be explained with reference to FIGS. 8 to 11. 8 is an overall perspective view of the engine room inspection wagon C, FIG. 9 is a view taken along arrows IX-IX in FIG. 8, FIG. 10 is a power supply wiring diagram of the wagon C, and FIG. This is a front view of the engine room inspection wagon accommodation unit G (hereinafter referred to as accommodation unit G) in a state where the engine room inspection wagon accommodation unit G (hereinafter referred to as accommodation unit G) is shown. As shown in FIG. 8, the engine room inspection wagon C has a cart C4 with casters C2, and a box-shaped work stand C6 is placed on the cart C4. On the side of this work stand C6 is a tune-up tester C for detecting engine speed etc.
8 is stored. Furthermore, a storage box C10 with an open top is installed beside the work stand C6, and the tools C12 necessary for inspecting the engine room are stored in this storage box C10.
It also houses a C14 timing light for adjusting ignition timing. This engine room inspection wagon C is shown in Figure 1.
It is manufactured in a shape that can be stored in the housing unit G shown in 1, and is pulled out from this housing unit G and used near the vehicle when inspecting the vehicle. Note that when the engine room inspection wagon C is stored in the housing unit G, the left end in FIG. 8 is the front side.

The tune-up tester C8 (see FIG. 10) is a measuring device for detecting the engine speed as described above, and the measuring clip C81 is connected to the engine speed check terminal (not shown). By connecting it, it receives the engine speed signal and displays this value. Note that this tune-up tester C8 has a structure that can be used for both gasoline engines and diesel engines. Furthermore, inside the tune-up tester C8, a battery power supply device (DC 12.6V) is installed.
) are stored. This power supply device is used not only as a power source for the tune-up tester C8 itself, but also as a backup power source for the vehicle. That is,
The battery power supply device has a cigarette lighter connector C8.
When this cigarette lighter connector C82 is inserted into the cigarette lighter socket of the vehicle, the battery power supply device is connected to the electric circuit of the vehicle. As a result, even if the battery in the engine compartment is removed from the vehicle, the CPU in the electrical circuit
Data can be stored because a voltage is applied to the

The timing light C14 is an instrument that indirectly detects the discharge (ignition) of the spark plug from the energization state of the secondary high-voltage line connected to the spark plug, and turns on the light in synchronization with the timing of the ignition. . This timing light C14 also has an internal battery for lighting the light.

As shown in FIG. 10, the instrument power supply (DC 12.6V power supply) for the tune-up tester C8, timing light C14, etc. is connected to the charging device G2 of the accommodation unit G via the charging connection connector CG30 for engine room inspection. It is supplied to wagon C. Here, since the tune-up tester C8 and the timing light C14 are each provided with power connectors C83 and C141, by removing these connectors C83 and C141, the tune-up tester C8 and the timing light C14 can be connected to the engine room inspection wagon. It can be used even when removed from C.

As shown in FIGS. 8 and 9, the charging connection connector CG is provided on the rear surface of the engine room inspection wagon C.
The male connector C30 of 30 is attached in a protruding state, and the female connector G3 of the charging connection connector CG30 is installed inside the housing unit G as shown in FIG.
0 is installed. Then, the charging connection connector CG30 is automatically engaged in a state in which the engine room inspection wagon C is housed in the housing unit G to the limit position. Therefore, when the engine room inspection wagon C is stored inside the storage unit G, power is automatically supplied to the tune-up tester C8 and the timing light C14, and charging is performed. Furthermore, when the engine room inspection wagon C is pulled out from the storage unit G, the charging connection connector CG30 is disengaged and charging of the tune-up tester 8C and timing light C14 is automatically stopped.

In this way, when the engine room inspection wagon C is not in use, that is, when the engine room inspection wagon C is stored in the storage unit G, the tune-up tester C8 and timing light C14 are automatically turned off. As a result, these instruments C8 and C14 are fully charged when they are used for the next inspection of the vehicle. This prevents malfunction of the meter due to a drop in power supply voltage during use. Furthermore, the tune-up tester C8 is of a type that can be used for both gasoline engines and diesel engines, and can also be used as a backup power source for vehicles, reducing the number of types of instruments required when inspecting and repairing vehicles.

(2D) Cooling Water Exchange Wagon Next, the cooling water exchange wagon D will be explained with reference to FIGS. 12 to 16. This cooling water exchange wagon D is a work unit for exchanging engine cooling water and long life coolant (hereinafter also abbreviated as LLC). Conventionally, when replacing engine coolant, the old coolant was drained by opening the engine and radiator drain cocks, and new coolant was injected through the radiator cap opening. For this reason, there were problems in that the old cooling water splashed against members of the lower part of the vehicle body, and that air was likely to get mixed into the new cooling water. Therefore, in order to prevent such a problem from occurring, in this embodiment, the cooling water is replaced by expelling the old cooling water with pressurized water. That is, the coolant in the engine and radiator is replaced by injecting pressurized water from one mouth of the cooling waterway and discharging old coolant from the other mouth. At this time,
The old cooling water can be completely discharged by discharging the discharged water until it is no longer colored by LLC (usually red or green). Not only that, but the air is expelled using pressurized water, so air can be completely removed. The cooling water exchange wagon D is a complete set of equipment necessary for pressurized extrusion of such cooling water.

Reference numeral D20 in FIG. 12 is a base plate of the cooling water exchange wagon D. This base plate D20 has four casters D16 attached to caster receivers D18, and the wagon D can be easily pushed and moved. A frame body D14 is fixed to the base plate D20, and a front plate D10 is further fixed to the front side of the wagon of the frame body D14 by a mounting metal fitting D12. This front plate D10 is
Wagon D is the cooling water exchange wagon housing unit (D in Figure 1).
When stored in 1), it is designed to match the front of other wagon storage units and maintain an aesthetic appearance. A drainage tank D22 for receiving discharged old cooling water is placed in the lower part of the base plate D20 partitioned by the frame D14. This drainage tank D22 can be pulled out by holding the handle D23. Further, a drainage inflow hose D24 is attached from one corner of the frame D14 toward the inside of the drainage tank D22. This drainage inflow hose D2
A cooling water discharge hose D, which will be described later, is connected to the connection port (not shown) in 4.
By connecting the tips of 42, old cooling water can flow into the drain tank D22.

On the other hand, a storage box D40 is placed on the frame D14, and a cooling water discharge hose D42 used for exchanging cooling water and adapters are stored in this storage box D40. Also on the frame D14 is a water-absorbing polymer tank D3 in which powdered water-absorbing polymer is stored.
1 is fixed. This water-absorbing polymer tank D31
constitutes a water-absorbing polymer measuring device D30 together with the input lever D32 and the measuring case D39, and when the input lever D32 is pushed down, the measuring case D
The water-absorbing polymer D30 in 39 is put into the drainage tank D22.

Further, the LLC injection tank D50 is fixed to the frame D14 by an injection tank support column D51. This injection tank support column D51 has an elastic joint D
52 and D53, LLC injection tank D5
The height of 0 can be changed as needed. This LLC injection tank D50 has an injection port D55 (tank D5 in FIG. 12) shown in the sectional view of FIG. 15 at one end.
) which is hidden on the other side of 0. Also, as shown in the same figure, there is a sloped plate D54 on the bottom of the tank D50.
The LLC poured into the tank D50 is collected at the injection port D55 and is injected into the radiator. During this injection, the length of the injection tank support column D51 is changed to the elastic joint D52,
D53 is used to adjust the height of the injection port D55.

The storage box D40 further stores an injection adapter D43, a discharge pipe D44, a discharge adapter D45, and an injection pipe D46 shown in FIG. These parts are attached to the tips of the water hose S shown in FIG. 1 and the cooling water discharge hose D42 shown in FIG. 12, and are used for connecting to a radiator cap or the like. Among these, the discharge pipe D44 is made of a transparent material so that the color of the discharged water can be observed.

Next, the water-absorbing polymer measuring device D30 will be explained with reference to FIG. This water-absorbing polymer measuring device D30 is a device for measuring the amount of water-absorbing polymer necessary for solidifying old cooling water and disposing it into the drainage tank D22. A slit-shaped drop opening D34 is provided at the bottom of the aforementioned water-absorbing polymer tank D31 that stores the powdered water-absorbing polymer, and a correspondingly shaped slit is also provided on the opening/closing plate D33. . By sliding this opening/closing plate D33 with respect to the droplet D34, a droplet opening of any size can be obtained depending on how the slits of both are overlapped. This opening/closing plate D33 is connected to the closing lever D32 by a first joint D37, and by moving the closing lever D32 up and down, the opening/closing plate D33 slides. Furthermore, a second joint D3 is provided at the tip of the closing lever D32.
8 are connected. This second joint D38 is connected to the input port D36, and by moving the input lever D32 up and down, the input port D36 is connected to the input port D36.
Opens and closes for 35.

Normally, the input lever D32 is at the upper end position, so the opening/closing plate D33 is fully open and the input port plate D36 is fully closed. Therefore, the water-absorbing polymer in the water-absorbing polymer tank D31 is removed from the opening/closing plate D33.
It passes through the slit and falls, and is filled into the measuring case D39. When the input lever D32 is pushed down from this state, the opening/closing plate D33 is fully closed, and the input port plate D
36 is fully opened, and a predetermined amount of the water-absorbing polymer that was in the measuring case D39 is thrown into the drainage tank D22. When the input lever D32 is then pulled up and returned to the upper end position, new water-absorbing polymer passes through the slit in the opening/closing plate D33 and is filled into the measuring case D39, ready for the next loading.

Now, a cooling water exchange method using the cooling water exchange wagon D having the above configuration will be explained with reference to FIGS. 12 to 16. First, the tip of the water hose S shown in FIG. 1 is pulled down from the ceiling, and the end of the water hose S shown in FIG.
Connect to. Furthermore, this injection pipe D46 is shown in FIG.
It is connected to the middle of the cooling water piping made of a rubber tube that connects the engine room to the heater, indicated by 100. That is, the rubber tube is cut at the highest position using a cutting tool provided on the wagon D, and the injection pipe D46 is connected to the cut port on the side connected to the heater. The cut port on the side that connects to the engine room is closed with a cap. In this way, the water channel is connected only to the heater side (not shown). On the other hand, a cooling water discharge hose D42 is attached to the radiator cap portion 103 via a discharge adapter D45 and a discharge pipe D44. In addition, here, the cutting opening on the engine room side is
As mentioned above, since it is located at the highest position, even if tap water is supplied from the cutout on the heater side, the radiator cap 10
3, so it does not necessarily need to be closed with a cap.

[0055] In this state, tap water is supplied from the water hose S, and pressurized water is sent into the cooling water channel from 100 parts as shown in Fig. 14 . As described above, since the section 100 is closed, the pressurized water passes through a heater (not shown), is divided into two parts at section 106, passes through sections 101 and 104, and is discharged from section 103. The discharged old cooling water is transferred from the discharge adapter D45 and the discharge pipe D44 to the cooling water discharge hose D4.
2 and flows into the wastewater tank D22 of the wagon D. Note that 105 shown in the figure is a radiator fan. At this time, whether the old cooling water has been completely replaced with new tap water is determined by observing the color of the water discharged through the transparent discharge pipe D44. Old cooling water contains LLC, which is colored red or green, so it can be easily identified.

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

On the other hand, the old cooling water received in the drainage tank D22 is drained using the water-absorbing polymer metering device D30.
Add the water-absorbing polymer and let it solidify. By adding a predetermined amount of water-absorbing polymer in this way, the old cooling water in the drain tank D22 becomes solid. Furthermore, since the water-absorbing polymer is mainly composed of alcohol, the solidified old cooling water becomes flammable. Therefore, this solid old cooling water is then extracted from the wastewater tank D22 and incinerated by the wastewater incineration treatment facility. Above,
The engine cooling water and LLC (Long Life Coolant) replacement work is completed.

As described above, by using the cooling water exchange wagon D, the cooling water exchange work can be carried out comfortably without polluting the work area, and the air in the cooling water channel can be completely vented. Furthermore, by adding a wagon function, mobility is greatly improved and work becomes easier, and since the necessary parts are gathered in one wagon, cooling water replacement work can be done in a short time. Not only that, the old cooling water becomes solid, which makes it easier to dispose of, and also prevents the problem of water pollution caused by discharging it into general wastewater.

(3) Wagon storage unit When not in use, each of the above-mentioned wagons A to D is stored in a wagon storage unit provided at the opposite end of the workshop from the vehicle entrance, as shown in FIG. Care is taken to keep the environment tidy and tidy. At the same time, each wagon is designed to be fully integrated with the wagon storage unit when stored, preserving the aesthetics of the entire workshop. FIG. 1 shows a state in which the oil change wagon A is used and the other wagons are housed in a wagon storage unit. Next, each part of this wagon accommodation unit will be explained.

(3E) Oil Exchange Wagon Accommodation Unit Reference numeral E in FIG. 1 is an oil exchange wagon housing unit, which has a width and depth that perfectly accommodates the oil exchange wagon A. Therefore, when wagon A is accommodated, the front of accommodation unit E is the same as the other accommodated wagons B and C.
, D, K, L, and M, and is designed to keep the workplace tidy and tidy, ensure the safety of workers, and not spoil the aesthetic appearance. Furthermore, as explained in the section of the oil change wagon A, the storage unit E includes a waste oil recovery connector E21 and a new oil supply connector E2 shown in FIG.
2. Power connectors E27 are provided, and by storing wagon A in accommodation unit E, these connectors are connected to the corresponding connectors on wagon A side, and waste oil collection and new oil supply are automatically started. Ru.

The waste oil sent from the oil change wagon A to the waste oil recovery connector E21 passes through the waste oil pipe E2 and is stored in a large waste oil tank (not shown) installed behind the storage unit. In addition, new oil supply connector E2
A large fresh oil tank (not shown) is installed on the back side of 2. Then, the pump of wagon A connects the new oil tank to the new oil pipe E1 and the new oil supply connector E22.
New engine oil is sucked through and supplied to tank A26. The end of collection of waste oil and supply of new oil is determined by the weight sensor of wagon A, and is automatically stopped.

[0062] Here, the operation lamp E3 lights up while the pump of wagon A is in operation, and goes out when the pump stops. Therefore, if the operation lamp E3 is off, this indicates that the collection of waste oil and replenishment of new oil from the wagon A has been completed and the wagon A is ready for use. Note that the abnormality indicator lamp E4 lights up to give a warning when some abnormality occurs. Also,
The power connector E27 and the control section E6 of the accommodation unit E, and the control section E6 and a power line (not shown) installed on the back side of the accommodation unit, are connected by a power cable E5. In this way, just by storing wagon A in storage unit E, preparations for the next work are automatically carried out.
Wagon A is now on standby.

(3F) Brake Inspection Wagon Accommodation Unit Next, F shown in the figure is a brake inspection wagon housing unit in which the brake inspection wagon B is housed. This storage unit F is simply a storage space for the brake inspection wagon B, and does not have any connectors to connect it to the wagon B, but its upper inclined plate has the following features as shown in FIG.
A pump power switch M40 is provided. This pump power switch M40 is for supplying power to the supply pump and discharge pump of the brake fluid supply and discharge equipment M that is operated when the wagon B is used. This brake fluid supply and discharge equipment M will be described later (see (3M)).

(3G) Engine Room Inspection Wagon Accommodation Unit Furthermore, reference numeral G in FIG. 1 is an engine room inspection wagon accommodation unit, in which the engine room inspection wagon C described above is accommodated. As shown in FIG. 11, inside the accommodation unit G, there is a charging connection connector CG.
30 female connectors G30 are attached. As described above, this female connector G30 is attached at a position where the male connector C30 provided on the back surface of the wagon C is fitted when the wagon C is accommodated. Therefore, simply by storing wagon C in housing unit G, both connectors C30 and G30 are connected.
The rechargeable battery in Wagon C is automatically charged.

(3H) Clean workbench Next, Figure 17~
The clean workbench H will be described with reference to FIGS. 18 and 21. This clean workbench H is for efficiently and cleanly disassembling and maintaining a brake master cylinder. Further, cleaning of the air cleaner element is also performed on this clean workbench H. In particular, inspection of the master cylinder is considered an essential item in vehicle inspection, and is an indispensable task in automobile maintenance. This work is actually performed prior to the brake fluid replacement and brake inspection work by the brake inspection wagon B described above.

First, FIG. 21 will be explained. Reference numeral U20 is a drain hose used to suction and remove fluid from the reservoir tank of the brake cylinder. This discharge hose U20 is stored wrapped around a hose drum U10 installed on the ceiling, and by rotating the hose drum U10, the tip of the discharge hose U20 is brought close to the floor of the workplace. It is possible to take it down. The rear end of the discharge hose U20 is connected to the hose connection U of the hose drum U10.
12, and a brake fluid discharge hose U is connected to this hose connection portion U12.

This brake fluid discharge hose U passes above the ceiling, goes down the back side of the wall (not shown) that is in contact with the back plate of each wagon housing unit, and further penetrates the back plate of the housing unit M1, as will be described later. It is connected to brake fluid supply and discharge equipment M. Then, by turning on the pump power switch M40 described in section (3F) above, the discharge pump M24 of the supply/discharge equipment M is activated, and the used brake fluid is discharged from the tip of the discharge draw-out hose U20. It can be inhaled and discharged through the brake fluid discharge hose U. Here, before disassembling and servicing the master cylinder, only the fluid in the reservoir tank is drained, and some fluid still remains in the master cylinder. Therefore, when the master cylinder is disassembled, this residual fluid will overflow and contaminate the surrounding area. In order to prevent this, a clean workbench H shown in FIGS. 17 and 18 is provided.

As clearly shown in FIG. 17, the framework of the clean workbench H includes a floor plate H1 on a workbench base H50.
0. It is composed of a left side plate H12, a back plate H16, a right side plate H32, and an upper inclined plate H20. Upper inclined plate H2
0 is provided with a large opening H11, and this opening H1
Each of the above plate materials H10, H12, H16, H32, H in 1
20, a work space H for performing disassembly and maintenance work
1 is formed. The overall outer shape of the clean workbench H is designed to match the outer shape of other wagon storage units. A vice H40 for holding automobile parts such as a master cylinder is attached to the center of the floor plate H10 via a pedestal H38. On the other hand, back plate H
An air gun holder H24 is fixed diagonally upward on the right side of the air gun 16, and the tip of an air blow gun H28 is inserted into this air gun holder H24 and hung thereon. An air hose H30 for supplying compressed air is connected to the air blow gun H28. The air hose H30 passes through the back plate H16 and is connected to an air compressor (not shown) located behind it.

On the inside of the upper inclined plate H20, above and below the opening, running water supply pipes H13, H22, H33 and H34 are provided, respectively, as shown by dotted lines in FIG. These running water supply pipes H13, H22,
A water pipe (not shown) extending from the water hose S shown in FIG. 1 is connected to H33 and H34, and this water pipe is opened and closed by a solenoid valve (not shown). The running water supply pipes H13, H22, H33, and H34 have many small holes along their axial directions, and when water is supplied from the water pipes, a shower-like water flow is created as shown in Figure 18. H42 and H44 are generated. These water flows flow through the three walls and floorboard surface of the work space H1, are collected in a long groove-shaped drain hole H53 provided at the back of the floorboard H10, fall down a drain pipe H54, and are discharged from a drain port H60. Ru. Here, like the running water supply pipe H34, the drain port H53 is provided in a continuous long groove shape from the left end to the right end of the floorboard H10, so the running water supply pipe H3
The shower-like water flow from 4 does not become thinner on the way,
It flows over the entire floorboard H10 while maintaining its initial width. This waste water is stored in a dedicated tank (not shown) provided behind the wagon storage unit, and is distinguished from waste water from hand washing J, which will be described later.

Further, on the back side of the back plate H16, as shown by the dotted line in FIG. 17, a suction pipe H36 is provided, and the upper end thereof becomes a horizontally long suction duct H37 that opens into the working space H1. There is. This suction pipe H36 is
As clearly shown in the side sectional view of FIG. 18, it is connected to the suction port of the vacuum motor H52, and dust generated in the working space H1 is removed through the suction duct H37 and suction pipe H36 by the operation of the vacuum motor H52. Dust, etc. can be removed by suction. In addition, work space H1
A total of three dust splash prevention wings H14, H18, and H26 are provided on the left, right, and upper sides of the chamber to form dust pockets to improve the suction dust effect.

[0071] Here, the drain pipe H54 and the drain port H
There is a water supply tube H56 inside the exhaust pipe H58 that connects the
and the shower umbrella H57 attached to its tip.
is provided. This shower umbrella H57 spreads the water flow coming out of the water supply tube H56, forming an umbrella-shaped water film H46. Therefore, when the exhaust gas discharged from the discharge port of the vacuum motor H52 passes through the exhaust pipe H58, the dust contained in the exhaust gas is adsorbed by this water film and washed away. This prevents the dust sucked from the suction duct H37 from being released into the atmosphere,
The air in the workplace can be kept cleaner. The air gun holder H24 is provided with a sensor switch (not shown), and when the sensor switch detects the removal of the air blow gun H28, tap water is supplied to the water pipes H13, H22, H33, and H34. No solenoid valve, and vacuum motor H52
The switch is turned on automatically. Therefore, when the air blow gun H28 is used, the water flow mechanism and suction mechanism within the working space H1 are automatically activated.

Now, the disassembly and maintenance work of the master cylinder using the clean workbench H having the above structure will be explained. First, the operator goes to the accommodation unit F, turns on the pump power switch M40, and operates the discharge pump M24. Next is Horse Drum U10
and rotate the hose drum U10,
Lower the discharge hose U20 to near the floor of the work area. Then, the tip of the discharge hose U20 is inserted into the reservoir tank from the upper part of the brake cylinder of the vehicle, and the fluid in the reservoir tank is sucked and discharged. When the fluid in the reservoir tank is completely drained, the operator then carries this brake cylinder to the clean workbench H and clamps and fixes it in the vise H40.

Then, the master cylinder is disassembled and the inside is cleaned with an air blow gun H28. At this time, the sensor switch of the air gun holder H24 is activated, and the water flow mechanism and suction mechanism are automatically activated as described above to wash away the remaining fluid in the master cylinder and the dust blown off by the air gun, and also to wash away the remaining fluid in the master cylinder and the dust blown off by the air gun. The dust generated inside is sucked through the suction duct H37. When the air blow gun H28 is returned to the air gun holder H24, water flow and suction will automatically stop. In this way, the master cylinder overhaul work is performed within the work space H1.

As explained above, water flows along the three walls and the bottom of the working space H1, and vacuum suction is applied at the same time, thereby preventing the adhesion and scattering of brake fluid, dirt, dust, etc. This allows you to keep the work area clean. After the master cylinder has been disassembled, cleaned, inspected, and worn parts replaced, the master cylinder is reassembled and installed in the vehicle. After this, as described above, the brake inspection work is performed using the brake inspection wagon B. Note that cleaning work for the air cleaner element is also performed on this clean workbench H in the same manner. Even in this work, the effects of running water and suction can prevent dust and the like adhering to the element from scattering into the work area.

(3I) Parts Basket Placement The upper surface of each of the wagon storage units mentioned above is an upper slope plate with a steep slope as shown in FIG. It looks like this. This naturally achieves the goal of keeping the workplace tidy and preserving its aesthetic appearance. However, in vehicle maintenance, parts baskets are used to temporarily store replacement parts and the like. If this parts basket is placed on the floor of the workshop, it will not only become cluttered and look unsightly, but also pose a risk for workers to trip over it. Therefore, in order to ensure the tidyness and safety of the workplace by limiting the location of this parts basket to one place, and to make it easier to see the contents of the basket and prevent people from forgetting to install parts, we created a parts basket storage I. is provided.

19 to 2 regarding this parts basket holder I
This will be explained with reference to 0. Reference numeral I10 is a parts basket placement base. On top of this is the main body I20 of the parts basket I
is provided, and its upper inclined plate I21 is made to have the same inclination angle as other wagon storage units and the like. Upper inclined plate I
21 is provided with an opening I23, and a punching board I22 is attached to cover this opening I23 from the inside.

The punching board I22 is shown in FIG. 20(a).
), (b), it is attached to the main body I20 by a spring-loaded hinge I26 at its lower end. The dimensions of the opening I23 and the punching board I22 are made to match the parts basket I30 to be used. Further, inside the main body I20, a board holder I28 is provided to connect both side plates. Further, a stopper I24 protrudes near the upper end of the punching board I22. In addition, as parts basket I30,
As shown in FIG. 19(b), a net-like basket made of plastic material is used for the purpose of making the contents easier to see.

When placing the parts basket I30 on this parts basket holder I, push the parts basket I30 into the opening I23 while pushing the punching board I22 with the tip of the parts basket I30 until it stops at the stopper I24. As a result, the parts basket I30 is placed on the punching board I22 supported by the board holder I28. On the other hand, when the parts basket I30 is not placed, the punching board I2
2 is the upper inclined plate I due to the biasing force of the spring-loaded hinge I26.
21, and the opening I23 is closed. Therefore, since the inclination of the punching board I22 matches the inclination of the upper inclined plate I21, the aesthetic appearance of the entire storage unit is not spoiled.

Furthermore, since the parts basket I30 is made of mesh-like plastic and the height at which the parts basket I30 is placed is close to the worker's eye level, the contents of the parts basket I30 can be easily viewed from a distance in the work area. This prevents forgetting to install parts. As the parts basket I30, in addition to the net-like basket in this embodiment, a basket made of transparent plastic or the like may be used.

(3J) Hand Wash Reference numeral J in FIG. 1 indicates a hand wash, which is provided above a waste basket K and a rag container L, which will be described later. This hand washing J
has an upper inclined plate J10 having the same angle of inclination as other wagon storage units, etc., and this upper inclined plate J10 is cut out to form a sink J20 with normal tap water piping installed therein.
is provided. Here, workers can wash their hands or wash them with water to keep them clean. The waste water is separated into waste water from the hand wash J and waste water from the clean workbench H, and each is stored in a dedicated tank (not shown) provided at the back of the wagon housing unit.

(3K) Wastebasket Reference numeral K in FIG. 1 is a wastebasket for disposing of iron scraps, paper scraps, etc. generated during work, and is provided on the lower right side of the handwash J. This wastebasket K is also a wagon that can be taken in and out of the wagon storage unit, and its interior is divided into two parts, front and rear. The front part is the iron scrap storage area,
It communicates with the opening/closing lid L20 provided at the upper front of the wastebasket K, and the iron scraps are thrown in by opening this opening/closing lid K20. Further, the rear part is a paper waste storage section, which is located directly below a paper waste inlet K10 provided at the rearmost part of the upper surface of the waste basket K, and paper waste etc. are thrown in from this paper waste inlet K10.

(3L) Also, the reference numeral L in FIG. 1 is a rag container containing rags for workers to wipe off dirt, dust, oil, etc. from parts. It is located below. This waste bag L is also a wagon that can be taken in and out, and the inside thereof is a waste storage box divided into two in the front and back direction. There is an unused rag in the front box, and this unused rag is in the rag container L.
It is taken out by opening the opening/closing lid L20 provided at the top of the front surface. On the other hand, the rear box is a storage section for used rags, and the used rags are thrown in from the old rag inlet L10 provided at the rearmost part of the upper surface of the rag container L.

(3M) Brake Fluid Supply and Discharge Facility Furthermore, reference numeral M in FIG. 1 is a brake fluid supply and discharge facility. As mentioned above, this brake fluid supply and discharge equipment M is equipment related to the brake inspection wagon B. As explained in the Wagon B section, in order to replace the brake fluid, there are two conditions: one with the brake depressed, that is, with pressure on the brake fluid, and one with the brake not depressed, with no pressure on the fluid. It is necessary to create it. In conventional replacement methods, two operators were required for this purpose. In other words, while one person operated the brake pedal inside the car, the other person had to perform the operations to bleed the air. By using this brake fluid supply and discharge equipment M and the aforementioned brake inspection wagon B, this work can be carried out safely and reliably by one person.

This brake fluid supply and discharge equipment M is shown in FIG.
1, a brake waste oil container M1 is attached to a main body M12 having four casters M10 similar to other wagons.
4. It is equipped with a brake fluid tank M16, a supply pump M22, a discharge pump M24, a solenoid valve M26, etc. The brake waste oil M14 is a discharge pump M2, which will be described later.
This is a container that receives the brake waste oil collected by No. 4. A pipe (not shown) is connected to the brake waste oil container M14 from the discharge port of the discharge pump M24, and a discharge pipe M30 is connected to the suction port of the discharge pump M24. This discharge pipe M30 passes through the back plate of the storage unit M1 (located under the parts basket I) of the brake fluid supply and discharge equipment M, and is connected to the brake fluid discharge hose U.

As described above, this brake fluid discharge hose U is connected to the hose connection portion U12 of the hose drum U10 through the back side of the wall (not shown) and above the ceiling. The hose connection part U12 is the hose drum U1
Discharge drawer hose U2 wrapped around and stored in
0, and by rotating this hose drum U10, the discharge drawer hose U20 can be lowered from the ceiling to the workplace.

On the other hand, new brake fluid is stored in the brake fluid tank M16. This brake fluid M16 is supplied to the pump M16 by a pipe (not shown).
22, and a supply pipe M28 is connected to the discharge port of the supply pump M22 via a solenoid valve M26. This solenoid valve M26 is connected to the supply pump M2.
2 and the supply pipe M28 are connected so as to be openable and closable. This supply pipe M28 also passes through the back plate of the storage unit M1 and is connected to the brake fluid supply hose T. The brake fluid supply hose T also passes over the ceiling from the back side of the wall and is connected to a hose connection portion T12 of a hose drum T10 provided above the ceiling. The hose connection portion T12 communicates with a supply pull-out hose T20 wound around the hose drum T10.

The power line M32 of the supply pump M22 and the power line M34 of the discharge pump M24 extend from the back of the brake fluid supply and discharge equipment M, and are combined into one pump power line M38 midway. This pump power line M
As shown in the figure, 38 passes through the back plate of the storage unit M1 and enters the unit F from the back plate of the brake inspection wagon storage unit F, and is connected to a pump power source provided on the upper inclined plate of this unit F. It is electrically connected to switch M40.

Further, the solenoid valve signal line M36 for opening and closing the solenoid valve M26 also passes through the back plate of the storage unit M1 and connects to the brake fluid supply hose T.
, extends to the ceiling parallel to the brake fluid discharge hose U. It hangs down from the ceiling and is connected to the rail N1 via a cable/hose connector P. From this rail N1, as shown in Figure 6, the wiring cable O
3 is electrically connected to the remote control switch B6 of the brake inspection wagon B. Therefore, by operating this switch B6, the solenoid valve M26 is opened and closed, and the vehicle's brake fluid can be switched between pressurized and non-pressurized states by remote control (see explanation (2B) for Wagon B). ).

[0089] Needless to say, the front plate M18 of this brake fluid supply and discharge equipment M is also designed to be on the same surface as other storage units when stored, so as to maintain its aesthetic appearance. Furthermore, an opening/closing plate M20 that can be opened and closed is provided at the upper front of the supply/discharge equipment M.

(4) Ceiling Equipment (4N) Rail As clearly shown in FIG. 1, this vehicle maintenance device has a rail N installed on the ceiling. This rail N is arranged in a loop shape that goes around the vehicle. Figure 2
2, the rail N is the inner rail N
1 and an outer rail N2 are configured as a pair, and three conductors extending along the rail N1 are fixed to the inner rail N1 in a mutually insulated state. The outer rail N2 is a trolley O4 and a spot unit Q20, which will be described later.

(4O) Truck and Cable Hose FIG. 23 shows a perspective view of a portion of the rails N1 and N2 and the truck O4 that moves along them. In this drawing, the truck O4 is provided with an air hose operating rod O5 extending downward. As shown in Fig. 1, this operating rod O5 extends as far as the operator can reach and has a grip O6 at the end.
It is equipped with Therefore, if the operator moves while holding this operating rod O5, the cart O4 will also move along the rail N2.

A trolley O1 that moves along the rail N1 is also provided. Trolley O1 moves along rail N1 and brings three coils included in cable O3 extending from trolley O1 into contact with the three conductors fixed to rail N1. 3
Power supply voltage is supplied to two of the book conductors, and signals are sent and received through the remaining one. With this configuration, when the cable O3 is connected to the wagon, power is supplied to the wagon and signals can be sent and received to and from the wagon. The trolley O1 is driven by the truck O4 by a coupling O2.

(4P) The outside rail N2 of the hose connector corresponds to predetermined positions as shown in Figure 1, that is, both front and rear sides around the vehicle, and a total of 6 locations at the front and rear of the vehicle. A hose connector P is assembled at that location. This hose connector P is mainly composed of a tapping valve P1 assembled to a rail N2. Compressed air is supplied to the tapping valve P1 via an air hose P2. The tapping valve P1 has a built-in valve that releases compressed air from the air hose P2 when the valve element is pulled downward, and seals the compressed air from the air hose P2 when the valve element is pushed upward.

[0094] A permanent magnet is incorporated in the truck O4,
When the truck O4 moves to a position corresponding to the hose connector P, the valve of the tapping valve P1 is pulled down and compressed air from the air hose P2 is supplied into the truck O4. When the compressed air is sent into the truck O4, the truck O4

is driven up and down in the axial direction by the hydraulic lifting mechanism. At the upper ends of both struts V2 is a substantially rectangular plate pedestal V4 for supporting the body part between the front and rear wheels of the vehicle from below.
are placed parallel to each other. Further, a rack V6, which is a rod-shaped gear that moves up and down together with the support pillar V2, is installed in parallel with the support pillar V2 in the immediate vicinity of both the support pillars V2. These racks V6 have a gear mechanism (not shown)
are engaged, thereby allowing both columns V2 to move up and down in synchrony. Furthermore, this gear mechanism prevents the lift V from descending due to the weight of the vehicle even if the hydraulic lifting mechanism fails. In addition, the rack V
A pulse generator (not shown) for detecting the height of the lift V (the height of the plate pedestal V4) is connected to 6 via a pinion.

[0112] The lift V is operated from an operation panel F2 installed in the brake inspection wagon accommodation unit F. This operation panel F2 is equipped with a top position push button switch, an intermediate height push button switch, and a bottom position push button switch, so that the height of the lift V can be selected from three levels by operating the push buttons. It has become. Note that the specific height settings of the highest position, intermediate height, and lowest position of the lift V can be arbitrarily set according to the preference of the operator.

(5W) A tire hanger W is attached to a side surface V41 of a plate holder V4 provided at the upper end of the tire hanger lift V so as to protrude outward from the side surface of the lifted vehicle. The tire hanger W is for holding a wheel and its accessories that have been removed from the vehicle near the vehicle, and includes a tire receiving main swing arm W2 formed of a pipe into a substantially rectangular shape. A shaft (not shown) projecting horizontally from approximately the center of the side surface V41 of the plate holder V4 is inserted into the pipe W21 forming one side of the tire receiver main swing arm W2. Furthermore, a pipe W24, which is one side perpendicular to the pipe W21 of the tire receiver main swing arm W2, is connected to the side surface V41 of the plate holder V4 by joints W22, V42 and a lever W23 having a long hole in the joint part. . With this structure, the tire support main swing arm W2 can be moved from the same height position as the plate support V4 of the lift V as shown in FIG.
As shown in the figure, the shaft can be rotated by its own weight around the axis of the shaft to a position supported by the lever W23.

[0114] On one side W21 of the tire receiver main swing arm W2 through which the shaft is inserted and one side W24 perpendicular thereto, a tire receiver sub swing arm W6, which is also formed into a substantially rectangular shape with a pipe, is connected to a hinge W61 and a joint W62. , W25 and a lever W64 having a long hole in the joint portion so as to be rotatable within a predetermined range. Further, at a position opposite to this tire receiving sub swing arm W6, a tire receiving sub swing arm W4 having a similar structure is installed. With this structure, the tire receiving sub-swing arms W4 and W6 are
It can be rotated by its own weight around hinges W41 and W61 from a position at the same height as the tire receiver main swing arm W2 to a position supported by levers W64 and W44, respectively, as shown in FIG. In the state shown in FIG. 29, the side surface shape of the tire hanger W is trapezoidal with the tire receiving main swing arm W2 as the lower bottom and the tire receiving sub swing arms W4 and W6 as the legs. For this reason,
The wheel T passed through the tire receiver main swing arm W2 is
The ground contact surface contacts the tire receiving sub-swing arms W4, W6 and is held within the tire hanger W.

Two sets of tire hangers W are attached to one plate holder V4 of the lift V, and the ends of these tire hangers W are approximately aligned with the longitudinal ends of the plate holder V4. ing. Thereby, the tire hanger W does not get in the way when the wheels are removed from the lifted vehicle. In addition, a wheel cap hanger W is located between these two sets of tire hangers W.
70, a center ornament/half wheel cap hanger W72 and a hub nut receiving tray W74 are provided. FIG. 30 shows a state in which the lift V has descended to the lower limit position. When the lift V is lowered, part of the tire receiver main swing arm W2 and part of the tire receiver sub swing arms W4, W6 of the tire hanger W come into contact with the floor during the lowering, and the reaction force causes the tire hanger W to swing both ways. Arm W2, W4
, W6 are rotated around the shaft and hinges W41, 61. When the plate holder V4 comes into contact with the floor surface, the tire holder main swing arm W2 and the tire holder sub swing arms W4, W6 become equal in height to the plate holder V4.

[0116] According to this tire hanger W, a wheel removed from a lifted vehicle can be held in a position near the vehicle where it does not get in the way, without placing it on the floor. Therefore, the wheels removed from the vehicle do not interfere with the work. Wheel accessories such as wheel caps and hub nuts can also be stored using the wheel cap hanger W7.
Since they can be stored together in the 0 or hub nut tray W74, there will be no troubles such as loss.
