【Example】

 Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.

1, 2 and 3 are a front view, a plan view and a side view of a two-stage type automobile garage lifting device according to the present invention, respectively.

A column support steel material 2 is placed on the left side in the forward direction of the automobile on a foundation 2 embedded in a fixed floor 1, and columns 4 are installed upright at both ends of the steel material 2. Pulleys 5 and 5'are rotatably attached to the tops of the columns 4, and the outer ends of the wire ropes 6 and 6'hanging on the pulleys are provided at the upright portions 7a and 7a of the side portions of the lift 7. ′ And the other inner ends are respectively fixed to the upper edges of both sides of the weight 8 which is a box-shaped container capable of being filled with water.

The lifting platform 7 includes two L-shaped steel main frames 7b, a support frame 7c arranged at right angles to the main frames, and a seat plate 7d placed on these frames and welded. Consists of. The lifting table 7 has a sufficient weight of 800 kg, for example, and has sufficient strength. The lift table 7 has guide rollers 9, 9'fixed to the main frame 7b and the seat plate 7d on the side surface thereof, and these guide rollers are provided on one side of the columns 4, 4'when the lift table is lifted. It is useful for guiding the lift 7 while rotating on the top.

On the other hand, the weight 8 is a box-shaped thin container as described above, and is designed to hold water therein. For example, the weight 8 has dimensions of 260 cm in width, 169 cm in height, and 23 cm in inner width, and can have a volume of 0.94 m ³ and its own weight of 720 kg. This value is a standard value, and the production specifications can be changed depending on the model of the vehicle in which it is installed. However, even if the weight is changed, the weight 8 must always land on the ground when the lift 7 reaches the raised position. In this way, when the weight difference between the weight of the lifting platform 7 and the weight of the vehicle is equal to the weight of the vehicle 8 by pouring or draining water on the weight 8, the lifting platform 7 on which the vehicle is mounted will move at a safe speed. It can move up and down smoothly.

Next, FIG. 4 and FIG. 5 are shown in order to make it possible to arbitrarily adjust the ascending / descending speed of the lifting platform 7 connected to the weight 8 with a wire rope and the volume of water injection and drainage to the weight 8. The electric terminal board 10 of the construction and the terminal receivers 11 and 11 'of the weight 8 (FIG. 3) are required.

The electric terminal board 10 is built in the pillar 4, and the upper copper plate 13 hung around the roller 12 provided on the upper part of the pillar is a guide provided on the inner side surface of the pillar 4 by its linear portion. The lower copper plate 17 that is slidably guided up and down in the groove 14 and the guide groove 15 provided on the outer side of the pillar 4 adjacent to the side surface of the weight 8 and is hung around the roller 16 provided at the lower part of the pillar. A guide groove 15 provided on the outer side of the support column 4 adjacent to the side surface of the weight 8 and a guide plate 18 provided on the inner side surface of the support column 4 are vertically slidably guided. The lower copper plate 17 is guided upward in the inner guide groove 18 via the deflecting roller 19, but the teeth 20 are cut in the end region of the lower copper plate 17, and the upper copper plate 17 is similarly guided in the inner guide groove 14. The teeth 21 are also cut in the end area of the copper plate 13. The teeth of these copper plates mesh with a gear wheel 22 provided therebetween. The gear 22 is attached to the shaft of a small motor 23. An insulating band 24, which is a space, is present between the weights 8 of the upper copper plate 13 and the lower copper plate 17 and the adjacent linear portions 13a and 17a. Both ends of the upper and lower copper plates 13 and 17 are connected to a power source through conductive wires as shown in FIG. When the motor 23 is rotated in the normal or reverse direction, the upper and lower copper plates 10 and 17 meshing with the motor 23 are moved up and down through the gear 22 to move the insulating band 24 between the weight 8 and the adjacent linear portions 13a and 17a. Spreads or shrinks. As a result, the speed of the lifting table 7 and the time for water injection and drainage can be automatically adjusted, as will be described later.

On the other hand, on the side surface of the weight 8 facing the electric terminal panel 10, terminal receivers 11 and 11 '(FIGS. 3 and 6) are fixed to the upper and lower parts. The contact 25 of the terminal receiver 11 is guided in a contact guide 26 fixed to the side surface of the weight 8 and is urged by a spring 27 so as to constantly contact the linear portion 13a or 17a of the upper and lower copper plates.

FIG. 6 shows an operation circuit for operating the electric terminal board 10 and the terminal receiver 11 configured as described above. In the position of FIG. 6, the weight 8 is at the upper end position, and the lifting platform 7 is at the lower position. When the water injection push button 30 is pushed in this position, the relay coil R ₁ is excited and the relay switch R ₁ ′ is held by itself, and the motor 31 rotates to rotate the pump 31 ′. As a result, water is sucked up from the tank 32 and poured into the weight 8. When the weight 8 becomes heavier and a weight difference occurs between the weight 8 and the lifting table 7 on which the vehicle is placed, the weight 8 starts to descend while water is being poured, and the lifting table 7 also starts to rise. When the end receiver 11 'of the weight 8 leaves the fixed point position 13b at the end of the copper plate 13a, the electric circuit is cut off, the pump 31 stops, and the water injection stops, so that the weight 18 further descends while moving by itself. At the same time as stopping at the position, the lifting table 7 further rises and stops at the rising position. For further safety, well-known appropriate brakes can be attached to both the strokes of the weight 8.

Next, when lowering the elevator table 7 on which the vehicle in the raised position is lowered, when the drainage push button 33 is pressed, the relay coil R ₂ is excited and the relay switch R ₂ ′ is self-held and the electromagnetic switch R ₂ ′ is held. Since the valve 34 is excited to change from the shut-off position in FIG. 6 to the communication position, drainage from the weight 8 is started. When the weight 8 becomes lighter and a weight difference occurs between the weight 8 and the lifting platform 7, the weight 8 begins to rise while draining, and at the same time, the lifting platform 7 begins to descend. When the terminal receiver 11 of the weight 8 leaves the fixed point position 17b, the electric circuit is cut off and the solenoid valve 34 is switched to the cut-off position. It further descends and stops. Therefore, as described above, by rotating the motor 23 of the electric terminal board 10 in the clockwise direction in FIG. 5 to increase the length of the insulating strip 24 between the copper plates 13a and 17a, the time for water injection and drainage can be shortened. This makes it possible to achieve a safe speed adapted to a light vehicle, while rotating the motor 23 in the counterclockwise direction to shorten the length of the insulating strip 24, the time for water injection and drainage is increased, and a heavy vehicle is used. A safe speed adapted to is possible. In this way, the fixed point positions 13b and 17b can be changed according to the vehicle type of the vehicle in which the occupant himself / herself mounts, and thus the length of the insulating band 24 can be easily adjusted.

7, 8 and 9 show an anti-slip lock of the weight 8 for automatic locking for safety when the weight 8 is raised and reaches the raised position. An arcuate locking piece 36 is pivotally attached at 37 to the appropriate position of the two columns 4 and is constantly biased towards the weight 8 by a spring 38. The tip of the locking piece 30 is pulled by a towline 39, and one end of the towline 39 is fixed to a handle wheel 40 as shown in FIG. When the lifting platform 7 being lowered is about to land, as shown in FIG. 7, the lifting weight 8 has its upper side surface abutting against the tip of the locking piece 36 and resists this against the spring. Ascend while pressing. When the weight 8 passes the tip of the lock piece 36, the tip of the lock piece 36 enters under the weight 8 by the spring 38 as shown in FIG.

Further, when the lifting table 7 is to be lifted, the suspension must be removed. In this case, when the vehicle is mounted on the lifting table 7, the weight 8 is filled with water due to the weight of the vehicle. Since it is levitating until it advances, it is possible to easily rotate the locking piece 36 by pulling down the handle 40a of the handle wheel 40 to which the towline 39 is fixed as shown in FIG. it can.

Next, FIGS. 10, 11 and 12 show an example of a solenoid valve 34 for discharging water in the weight 8 of the present invention. This electromagnetic valve 34 has a cylindrical case 41 attached to the bottom of the weight 8, and in this cylindrical case 41, a well-known electromagnet 42 having a coil wound around an iron core, and a slide on the electromagnet 42. It is composed of a soft iron piece 43 that is movably sucked and a spring 44 supported by a partition wall 45 that constantly biases the soft iron piece 43 away from the electromagnet 42. In the excitation position of the electromagnet in FIG. 10, the soft iron piece 43 is attracted to the electromagnetic stone 42 to open the drainage port 8a at the bottom of the weight 8, and in the non-excitation position in FIG. 11, the drainage port is pushed by the spring 44. 8a is closed. If a non-magnetic buffer ring 46 is applied to the magnetic poles of the electromagnet 42, the soft iron piece 43 can be easily removed.
