Abstract

PURPOSE:To provide a pit struction that is easy to handle the constituent parts of a radiator and a cooler or the like. CONSTITUTION:When an automobile is set on a pit 1, width of the pit 1 of a more front part than a position where the front wheels are stopped is made wider than a more rear part than that, while a bottom face of the pit 1 of a part where a table lift is attached is made deeper as far as 1000mm or so than that of a more rear part than that, whereby a table 2 is made so as to be lowerable up to a deeper position as far as 400mm or so than the bottom face of a more rear part of the pit 1, while this table is made so as to be liftable up to a higher position as far as 400-1000mm than a floor surface of a work section, thus it is constituted so as to be usable as a car lift.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automobile maintenance pit equipped with a table lift.

[0002]

2. Description of the Related Art Generally, an automobile is provided with various members such as a power mechanism such as an engine, a transmission, a differential gear box, a radiator, and a cooler. Most of these are installed on the underside of the car body, so a car garage has a pit formed on the floor of the workshop where the car can be placed on top of which the worker can enter the pit for repair. I am supposed to do other work.

[0003]

As described above, most of the power mechanism and accessory members of the automobile are detached from the lower side of the vehicle body for repair or attachment. However, since the pit is formed to be much narrower than the distance between the two wheels in order to ensure safety when the vehicle is placed on the pit, it is difficult to handle the member removed from the vehicle body in the pit. Moreover, since the table lift cannot be made higher than the floor surface of the work place, there is a problem in that work efficiency is low due to restrictions on removal and mounting of members and other work. An object of the present invention is to provide a pit structure in which members such as a radiator and a cooler are easy to handle.

[0004]

SUMMARY OF THE INVENTION According to the present invention, when a vehicle is placed on a pit, the width of the pit before the position where the front wheels of the automobile stop is smaller than the width of the portion after the front wheel. Also, the bottom of the pit where the table lift is mounted is 10 mm wider than the bottom of the part behind it.
It should be deeper by about 00 mm so that the table can be lowered to a position about 400 mm deeper than the bottom of the rear part of the pit, and this should be 400-1000 deeper than the floor of the workplace.
It is possible to fry to a position about mm high,
The above-mentioned object is achieved by means configured so that it can be used as a vehicle lift.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The pits according to the present invention will be specifically described below based on the illustrated embodiments. In the figure, reference numeral 1 is a pit, 2 is a table, and 3 is a wheel stopper. This embodiment shows a pit adapted to be applied to vehicles from small vehicles to large vehicles.
It is formed with a length of about 000 to 15,000 mm, and the table 2 is attached within a range of about 7,000 to 8,000 mm from its front end. Wheel stoppers 3 are formed on the floor surfaces 4 on both sides at a position of about 10000 to 11000 mm from the rear end of the pit 1, and the vehicle to be repaired is advanced from the rear end of the pit 1 to When the front wheels reach this position, they are stopped. The width of the pit 1 is several hundred mm from the position where the wheel stopper 3 is formed to 1000 from the front to the rear end.
About mm, the safety when setting the car on this is secured, and before that, it is about 1400 to 1600 mm, which makes it easy to work in it. The depth of the pit 1 is about 1300 mm from the rear end to the place where the table 2 is attached, and before that, the range where the table 2 is attached is 2300 to 25.
It is about 00 mm. At the rear end of this pit 1, stairs 11 are formed for workers to enter and exit.
A ladder 12 is attached to the front end. Further, jack rails 13 are attached to the upper edges of both sides of the pit 1 so that a jack 14 using a hydraulic cylinder can be run along the jack rails 13. Table 2 has a length of 7,000
Approximately 8000 mm, the plane shape is slightly smaller than the inner edge shape of the rear part of the pit 1, and the lifting mechanism 5 is provided between the lower surface of the pit 1 and the bottom surface of the pit 1, and the table 2 is about 1700 mm. 400 from the floor of the workshop from the depth of
It goes up and down to a position about 1000mm higher and stops at any position in between. A skirt 23 is attached around the table 2 so that the table 2
Accidents in which the space between the table 2 and the pit 1 is closed when the car is lifted higher than the floor surface 4 of the work place, and the members and tools removed from the automobile or the workers fall into the pit 1 through the space. Is preventing. The operation of raising and lowering the table 2 can be performed by either the foot switch 21 attached to the front end of the table 2 or the push button switch 22 attached at an appropriate position on the inner wall surface of the pit 1. Especially, this table 2 has a switch 21,
Or you can press 22 to move up and down, and when it reaches an arbitrary position, turn off the switch to stop it, and if you keep pressing it, table 2 will be at the top. , And the same height as the floor surface 4, the same height as the bottom surface of the rear part of the pit 1, and when reaching the lowest position, stop the operation once and then press the switch again to continue the ascent / descent. ing. Further, when the detection switch 15 is attached to the side edge of the pit 1 slightly in front of the position of the rear end of the table 2, and the table 2 is at a position higher than the bottom surface of the rear part of the pit 1, If the jack 14 does not move forward than this and the jack 14 is in front of the position where the detection switch 15 is attached, pressing the switches 21 and 22 prevents the table 2 from rising. There is. Although not shown, a water pipe is attached to the bottom surface of the pit 1, and a manual jack, a wheel stopper, etc. can be stored on the inner side surface. Facilities are provided.

[0006]

As described in detail above, according to the present invention, when the vehicle is placed on the pit, the width of the pit in front of the position where the front wheels of the vehicle stop is widened and the table lift is increased. Same as the bottom of the pit, and even more
Since it can be lowered to a position about 400 mm deep, it is possible to easily attach and remove power mechanisms such as transmissions and auxiliary members such as radiators, and also The handling of the members becomes easy and the efficiency of maintenance work is significantly improved.
Also, by making it possible to lift the table up to 400 to 1000 mm higher than the floor of the workplace, this can function as a lift and lift the front part of the car, improving the efficiency of maintenance work. It will be further improved. Since the table is sequentially stopped at predetermined positions, there is an advantage that the lifting operation can be performed very easily.
