[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. In particular, many of these are attached to the underside of the vehicle body, so that maintenance and repair work of the vehicle must be performed from under the vehicle body. For this reason, the floor of the workshop of an automobile repair shop has a depth of 1,300
A pit with a width of 1,400 to 1,600 mm is formed.By placing the car on this pit and allowing workers to enter it, repairs and other work can be performed from the bottom of the vehicle body. ing. This pit is formed to be much narrower than the distance between its two wheels in order to ensure safety when installing a car.Here, parts such as the engine and transmission are removed from the vehicle body and new parts are installed. Only the work of doing and the work of adding repair work such as welding to the car body are performed.

[0003]

As described above, since the pit is formed narrowly, the work in it is considerably restricted. For example, a large member such as an engine or a transmission is simply a vehicle body. It is only removed from or attached to, and no repair work is performed on it. Moreover, it has been difficult to even raise these large-sized members to a predetermined height for mounting and to remove the removed ones. An object of the present invention is to provide a table lift in which members such as an engine, a transmission and a cooler can be easily handled.

[0004]

SUMMARY OF THE INVENTION According to the present invention, a table lift is provided in a portion of a pit for automobile maintenance, and the table is moved up and down from a position about 400 mm higher to a position about 400 mm lower than the floor surface of the pit. This table is composed of a main table and a sub-table, and the sub-table can be raised to the same height as the floor of the workplace independently of the main table. By the means, the above-mentioned object is achieved. It is also possible to form an embodiment in which a work pit having the same depth as that of the pit is formed at the front end of the pit so that members such as an engine and a transmission can be repaired here.

[0005]

According to the present invention, the table of the table lift provided in the automobile maintenance pit is composed of the main table and the sub-table, and the sub-table is lifted up to the same height as the floor of the workplace independently of the main table. By making it possible to do so, a member such as a transmission, a repair device, and the like are placed on and taken out of the device.

[0006]

[Embodiment 1] Hereinafter, a pit according to the present invention will be specifically described based on an illustrated embodiment. This embodiment shows a double pit which is applied to a large-sized automobile, and the table lift is formed in a portion near the front of the pit 1. In this embodiment, the pit 1 has a length of about 14,000 to 15,000 mm and a depth of about 1,300 mm.
Wheel stoppers 3 are formed on the floors 4 on both sides at a position of about 11,000 mm, and the vehicle to be repaired is advanced from the rear end side of the pit 1 and stopped when its front wheels reach this position. It is like this. The width of this pit 1 is about 1,400 to 1,600 mm, in which work such as removing components such as the engine and transmission from the vehicle body, mounting new components on it, and repairing welding etc. to the vehicle body It is possible to perform work such as adding processing, and it is a few hundred mm from the position where the wheel stopper 3 is formed to 1,000 from the front to the rear end.
By attaching the jack rails 13 at intervals of about mm, the apparent width of this part is set to about 1,000 mm,
Safety is ensured when a car is placed on this. Further, a range of about 7,000 to 8,000 mm from the front end is a recess having a depth of about 2,500 to 3,000 mm, and a table lift having a table of a plane shape almost the same as this recess is provided. The table is the main table
It consists of 21 and vice table 22. The main table 21 is
It is directly attached to the underframe 51 that is moved up and down by the main lifting mechanism 5 in the recess, and is moved up and down from a position about 400 mm higher than the bottom surface 12 of the pit 1 to a position about 400 mm lower than the bottom surface 12 of the pit 1, and any position in between. The sub-table 22 is attached to the underframe 51 via the sub-elevation mechanism 52, and can be stopped at a position, from the same height as the main table 21 to the upper edge of the pit 1. That is, it is possible to raise to the same height as the floor surface 4 of the work place and stop at any position therebetween. Further, a skirt 23 is attached to the rear end of the main table 21, and when the main table 21 is lifted higher than the bottom surface 12 of the pit 1, the rear edge of the main table 21 and the front surface of the bottom surface 12 of the pit 1 are arranged. The gap between the edge and the edge is closed to prevent an operator's foot from entering here, a member or tool removed from the automobile, an operator, or the like from falling into the pit 1 through the gap. Similarly, a skirt 24 is attached to the rear end of the sub-table 22 and occurs between the rear edge of the sub-table 22 and the front edge of the main table 21 when it is fried higher than the main table 21. The gap is prevented to prevent an operator's foot from entering, a member or tool removed from the automobile, an operator, or the like from falling into the pit 1 through the gap. A foot switch 25 is attached near the front end of the sub table 22, and a push button switch 26 is attached at an appropriate position on the inner wall surface of the pit 1, and the underframe 51 can be attached by any switch.
It is possible to move up and down, that is, to move up and down the table. In particular, this table has a switch 25,
Or, when you press 26, you move up and down, and when it reaches an arbitrary position, turn off the switch to stop the elevator and fix it at that height, and when you continue to press it. When the main table 21 reaches the uppermost position, the same height as the bottom surface 12 of the pit 1 and the lowermost position, the main table 21 is temporarily stopped and the switch is pressed again to continue elevating and lowering again. Further, the switch 27 for independently raising and lowering only the sub table 22 is attached to an appropriate position outside the pit 1 (not shown) in addition to the same position as the above-mentioned switch, and any switch is used. You can do it. This sub-table 22 is moved up and down by pressing any switch, and when it reaches an arbitrary position, it can be stopped by turning off the switch, and it is also lowered. When sub table 22
Stops when it reaches the same height as the main table 21, forms the same plane as the main table 21, and when raised, stops when it reaches the same height as the upper edge of the pit 1, It is designed to be flush with the floor surface 4 of the workplace. When the sensor 15 is mounted on the side wall of the pit 1 at a position slightly apart from the rear end of the main table 21 and the table is located higher than the bottom surface 12 of the pit 1,
Do not move jack 14 further than this,
When is in front of the position where the sensor 15 is attached, the table is prevented from rising even if any switch is pressed. A staircase 11 is formed at the rear end of the pit 1 for workers to enter and exit, and jack rails 13 are attached to the upper edges of both sides of the pit 1, and a jack 14 using a hydraulic cylinder is provided. Is designed to run along this. Reference numeral 6 is a storage box, and 61 is its door. The storage 6 is formed on the side surface of the pit 1 so as to store and store the repair tool and the repair member. It can also be used as a tunnel when moving to the adjacent pit. Door 61
Is normally closed and is flush with the side wall of the pit 1 to form a part of the side wall. Although not shown, the table does not rise when the side wall is open.

It is possible to cross between the work pit 7 and the main table 21 across 28.

[0008]

As described above in detail, according to the present invention, the table lift is provided in the automobile maintenance pit so that the table is not restricted by the pit jack.
Since it is possible to move up and down from a position that is higher by about mm to a position that is lower by about 400 mm, there is an advantage that the maintenance work of the vehicle can be performed easily and efficiently.
Moreover, the table is composed of the main table and the sub-table, and the sub-table can be raised to the same height as the floor surface of the workplace, so that the members such as the engine and the pits of the repair device can be installed. In addition to the fact that the work of putting in and out of the car is significantly easier, and the member removed from the car body can be raised to the floor of the work place and repaired there, the efficiency of the maintenance work is further improved. Also, by fixing the sub-table at the same height as the floor surface, it becomes possible to repair the front part of the car.
Workers can now cross over the pit and pass heavy objects such as repair equipment, further improving work efficiency. When the working pit is formed, the member removed from the vehicle body can be laterally moved to the working pit for repair there, which has the advantage of eliminating the work of raising and lowering it.
