Description

[Detailed Description of the Invention] This invention provides for assembly and transportation of a place that can be disassembled and transported.
This invention relates to a lift device that can be easily disassembled.

You may be required to lift heavy objects to high places inside buildings.

For example, inside a building, there is a cooler that hangs out high above a window.
It may be necessary to install the The present invention aims to provide a lift device that is useful in such cases and is easy to assemble and disassemble. According to this invention, the cooler can be easily and safely lifted to a desired height by loading the lift device along with the cooler onto a truck, assembling the lift device near a window indoors, and placing the cooler over the entire area of the lift. It was made so that it could be done. An embodiment of the present invention will be described based on the drawings.

1 is a front leg member, 2 is a rear leg member, and the rear leg member 2 is attached to four mutually parallel horizontal frame portions H3, upper, lower, left and right, which are provided on the front leg member 1 to project rearward. Fit, bolt 4
When tightened, base A is constructed.

The front leg member 1 is provided with an actuator 5, and the rear leg member 2 is provided with a rear wheel 6. Reference numeral 7 designates a fixed support made of two parallel I-beams arranged in the vertical direction, and 8 represents two substrates that sandwich the lower ends of the fixed supports 7, 7.

Reference numeral 9 denotes an oil tank, which is surrounded by fixed columns 7, 7 and substrates 8, 8.

Reference numeral 10 denotes a hydraulic pump disposed on the oil tank 9, which is fixed to the base plate 8, and is adapted to pump out the oil in the oil tank 9 when a lever 11 is swung.

Reference numeral 12 denotes a movable support which is slidably fitted to the outside of the fixed support 7 from above, and 13 is a ceiling plate of the movable support 12.

14 is a hydraulic cylinder whose upper end is connected to the ceiling plate 13 and its lower end is connected to the hydraulic pump 10, and when the lever 11 is manually swung, the oil in the oil tank 9 is sent to the hydraulic cylinder 14. When the hydraulic cylinder 14 is extended and a cock (not shown) is opened, the oil in the hydraulic cylinder 14 is returned to the hydraulic tank 9 and the hydraulic cylinder 14 is shortened.

15 is a lift block fitted on the outside of the moving column 12.

Reference numeral 16 denotes a cable, which is hung on a wheel 17 attached to the upper end of the lowered movable column 12, and then connected at one end to the lowered lift block 15 and at the other end to the upper end of the fixed column 7. .

Therefore, when the hydraulic cylinder 14 is extended, the movable column 1
2 is guided by the trochanter 18 and raised, and at the same time, the lift block 15 is guided by the rollers 19 and raised. Elevating tower B is configured as described above. The board 8 of this elevator tower B has four holes 20, and after being inserted into the frame member 3, it is secured by the rear leg member 2. 2
Reference numeral 1 designates a lift arm, and the lift arm 21 hooks its hook portion 22 onto the lift block 15, and then attaches to the contact plate 23.
, and is fixed to the lift block 15 with thumbscrews 24.

The lift seat C is configured as described above. The lift device according to the present invention can be divided into three parts: a base A, a lifting tower B, and a lift seat C.

And it is extremely easy to assemble and disassemble. Therefore, when installing a cooler by protruding it from a building window, it is extremely easy to install this device by loading it into a truck together with the cooler and assembling it at the site. It is possible to install a cooler by protruding it. That is, in this invention, a groove formwork having a bent edge is slidably fitted to the outside of two parallel fixed columns 7, 7 made of I-shaped steel, and both groove forms are attached to the upper ceiling plate 13. and a lower base plate 8 to form a movable column 12. A hydraulic cylinder 14 is disposed between the fixed columns 7, 7, and the body of the hydraulic cylinder 14 is fixed to the fixed column 7. At the same time, the upper end of the piston of the hydraulic cylinder 14 is fixed to the ceiling plate 13, a manual hydraulic pump 10 for supplying oil to the hydraulic cylinder 14 is fixed to the base plate 8, and a lift block is attached to the movable column 12 so as to be able to slide up and down. 15, the wheel 17 is pivotally supported on the upper part of the movable support 12, the base end of the cable 16 hung on the wheel 17 is locked to the fixed support 7, and the tip of the cable 16 is locked to the lift block 15, The front leg member 1 is constructed by installing four vibrator-like frame members 3 on the upper, lower, left and right sides in parallel with each other and protruding rearward.
At the same time, the front leg member 1 is formed into a bifurcated shape facing forward, and the vibe-like frame member 3 of the front leg member 1 can be inserted and removed.
;． = Ginji! ,′Jx−↑? , &= A rear leg member 2 having a fitting hole into which the song 3 is removably fitted is provided, and a bolt for tightening and removing the vibrator-shaped frame member 3 fitted into the fitting hole of the rear leg member 2. 4, and the hook portion 22 of the lift arm 21, which can be positioned so as to fit between the two legs of the front leg member 1, is attached to the lift block 15.
It consists of a lift device that is easy to assemble and disassemble, and is characterized by being hooked onto a holder.It is highly effective in lifting and unloading heavy loads in narrow spaces.

Also, when the movable support 12 is extended with respect to the fixed support 7,
The lift block 15 can rise to the top of the moving column 12.

Therefore, when it is shortened, it is shortened to make it easier to transport.
When extended, items can be raised to a higher position. In the illustrated embodiment, the outrigger 5 is attached to the front leg member 1, but depending on the usage, wheels may be used instead of the outrigger 5.
