Abstract

PROBLEM TO BE SOLVED: To provide a safe pit cover even when a person rides on it by arranging the pit cover travelably via multiple wheels at the opening section of a pit, and forming the pit cover so that it sinks by the load applied on it and a part of it is kept in contact with the peripheral edge section of the opening section. SOLUTION: This pit cover 5 is formed into an insert-like double expansion structure having a box-like cross section, wheels 9a are coupled and rotated on rails 8 installed along both edges in the longitudinal direction of a pit 2, and the pit cover 5 is formed movably along the pit 2. The wheels 9a are fitted to both the inner and outer covers 5b, 5a via suspensions 9 respectively. When a person rides on the pit cover 5, the coil springs of the suspensions 9 are warped by the weight, grounding projections formed on the inner and outer covers 5b, 5a are grounded on the rails 8 below, and the movement of the outside cover 5a or inside cover 5b is limited by the friction between them.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for recovering waste oil from an automobile in an automobile repair shop or the like.

[0002]

2. Description of the Related Art Conventionally, as a waste oil collecting device of this type, a pit is provided on a floor surface and a waste oil receiver having an upper opening container is provided in the pit, and an automobile stops on the pit in a vehicle width direction. It was common to discharge waste oil into the waste oil receiver. Further, there is an example in which the waste oil receiver is formed so as to be movable along the pit in order to improve the reception of waste oil discharged from a vehicle.

Further, there is known an example in which a pit cover that can be opened and closed is provided on the pit in order to prevent accidents such as a person falling into the pit and improve workability.

[0004]

However, since the pit cover is reciprocally movable along rails provided on both sides of the pit, if a person inadvertently gets on the pit cover, However, there has been a problem in that the pit cover moves due to the reaction and the feet of the occupant become unstable.

[0005] It is an object of the present invention to solve these problems and to provide an automobile waste oil recovery device provided with a pit cover that is safe even when a person rides on it.

[0006]

FIG. 1 shows a first embodiment of the present invention.
This will be described with reference to FIGS.

FIG. 1 shows an example of an automobile maintenance shop equipped with an automobile waste oil recovery device 1 according to the present invention.

The waste oil recovery device 1 includes a pit 2 formed on a floor A, a moving frame 3 provided in the pit 2, a waste oil receiver 4, a pit cover 5 formed to be openable and closable, It comprises a pump 6, a waste oil tank 7, and the like.

FIG. 2 is an enlarged sectional view taken along the line II--II in FIG. 1. In FIG. 2, the moving frame 3 is mounted on rails 3b disposed along both longitudinal edges of the pit 2 by rollers. 3a is formed so as to be movable along the pit 2 by engaging and rotating.

The waste oil receiver 4 is in the form of a container with an open top, and is attached to the moving frame 3 via a lifting / lowering assisting means 3c. The waste oil receiver 4 is moved up / down from the moving frame 3 by the lifting / lowering assisting means 3c. It is free.

The pit cover 5 has a nested double telescopic structure with a box-shaped cross section. The inner cover 5b is slidably inserted into the outer cover 5a. The wheels 9a are formed so as to be able to move along the pits 2 by engaging and rotating wheels 9a with rails 8 installed along the pits.

In order to prevent the car from falling into pit 2,
A safety plate 10 is provided on the periphery of the pit 2.

FIG. 3 shows an extended state in which the inner cover 5b is pulled out from the outer cover 5a, and FIG. 4 shows a contracted state in which the inner cover 5b is inserted into the outer cover 5a.

On both sides of the front and rear end surfaces of the outer cover 5a, projecting portions 5c for grounding are formed.
Projecting portions 5d for grounding are formed on both sides of the rear end face b.

The protruding portions 5c and 5d are formed so as to be able to move through the rails 8 while maintaining a slight gap between the lower end portions thereof and the surface of the rails 8 on which the wheels 9a run. I have.

FIG. 5 is a view taken in the direction of the arrow X in FIG. 4, showing a state in which the outer cover 5a is viewed from the front end face. FIG. 6 is a view taken in the direction of the arrow Y in FIG. It shows the state that it was turned on.

Further, the outer cover 5a has a pair of wheels 9a before and after both sides, and the inner cover 5b has a pair of wheels 9a behind both sides.

Each of these wheels 9a is attached to both the inner and outer covers 5b, 5a via a suspension device 9, respectively.

The suspension device 9 comprises a bearing housing 9b, a ridge or coil spring 9c, a bracket 9d, two sets of pipes 9e and two sets of shafts 9f.

The bearing box 9b rotatably supports a wheel 9a. Two sets of shafts 9f project from the upper surface of the bearing box 9b and support one end of a coil spring 9c. .

The bracket 9d is provided with both inner and outer covers 5b,
A pair of pipes 9e are formed on the lower surface of the bracket 9d so as to protrude therefrom and support the other end of the coil spring 9c.

The shaft 9f is provided above the pipe 9e.
The shaft 9f and the pipe 9e
Is formed to be slidable telescopic.

The upper plate 5 of the inner and outer covers 5b, 5a
As shown in FIG. 7, e is formed of a perforated iron plate or a wire mesh to prevent slipping of shoes of a person riding thereon and to provide ventilation and ventilation to the lower pit 2.

FIG. 7 is a plan view when the outer cover 5a and the inner cover 5b are in the state shown in FIG.

Next, the operation of the first embodiment will be described.

The vehicle that performs waste oil is stopped on the pit 2 in the vehicle width direction, and waste oil is discharged into the waste oil receiver 4.

At this time, the waste oil receiver 4 can be moved along the rail 3b together with the movable frame 3, and the waste oil receiver 4 can move up and down from the movable frame 3, so that the direction of the drain opening of the automobile and the wind Also, the waste oil can be collected without scattering the waste oil to the side.

Since there is a pit cover 5, the pit 2
Not only when the pit is not used, but also when collecting the waste oil from the vehicle, the opening of the pit 2 is shielded to prevent a person from falling down, thereby improving workability. .

Further, even when a person rides on the pit cover 5, the coil spring 9c of the suspension device 9 is bent by the weight of the pit cover 5, and the protruding portion 5c or 5d is grounded to the lower rail 8, Since the movement of the outer cover 5a or the inner cover 5b is restricted by the friction between the two, the feet of a person riding on the cover do not become unstable.

In this embodiment, the protruding portions 5c or 5d for grounding are provided on both sides of the front end face or the rear end face of the inner and outer covers 5b, 5a. Projections for grounding may be provided below both sides of both covers 5b and 5a.

A second embodiment of the present invention will be described with reference to FIG.

The difference between the second embodiment and the first embodiment is that the pit covers 5 are provided in two upper and lower stages.

That is, the upper and lower two along the longitudinal direction of the pit 2
The rails 8 are installed on the steps, and each pit cover 5 is also composed of an outer cover 5a and an inner cover 5b.
The pit 2 was formed so as to cover the pits 2.

The feature of the second embodiment is that the opening portions of the pits 2 can be widely used by putting the two pit covers 5 in a contracted state and putting them side by side, which is convenient for work. is there.

In this manner, the effective opening area of the pit can be reduced to about 75% of the entire opening area of the pit.

[0037]

As described above, according to the present invention, the pit cover movably provided at the opening of the pit sinks by a constant load and comes into contact with the periphery of the opening. Because the pit cover is restricted, when a person gets on the pit cover, the pit cover stops without careless movement and is safe, and it is easy to completely close the pit opening and open the work area. It has a good effect that the workability is good.
