Description

Dual-purpose vertical lift platform for fixing and load-lifting

The utility model is a kind of can the finishing building, and dual-purpose lift platform (hereinafter to be referred as dual-purpose platform) that again can hoisting heavy relates to building engineering field.

In the existing building operations, add derrick with crane or hoist engine when lifting; Use scaffold when fitting up, minority unit in charge of construction construction hanging basket or lift platform.The utility model is that finishing platform and crane functions are combined, and relies on lift platform to improve the lifting altitude of lifting gear, relies on lifting gear to enlarge the function and the mounting or dismounting derrick guide rail standard knot of lift platform.

Feature of the present utility model is that lifting gear is installed on the lift platform, and And and self-dependent lifting mechanism are finished whole installations and set up work, needn't use other whiplines.

Existing accompanying drawings is as follows:

Fig. 1 is dual-purpose platform side view, derrick guide rail (3) is contained in one and takes back on the underframe (1) that changes supporting leg and trundle, lifting mechanism (2) is contained in the root of derrick guide rail (3), lift platform (4) relies on a stock (5) that has 16 trundles, can outside derrick guide rail (3), move up and down, can be fixed on derrick guide rail (3) by means of two security insurance pins (6) simultaneously and go up the appropriate location, to carry out fitment operation and slinging work.Lifting gear is made up of column (8), revolving body (9), jib (10), trailer wagon (11), suspension hook (12), manual several parts of winch (7).Column (8) is connected with stock (5) by 4 hinge pins, and hoist rope enters revolving body (9) from column (8) inside, reboots on dolly (11) and the suspension hook (12), is fixed on the arm end at last.Lifting mechanism (2) rotating can drive suspension hook (12) and rise or descend, and finishes slinging work.Can drive trailer wagon (11) with manual winch (7) and move horizontally, realize luffing.With pulling the rope that ties up on jib (10) or the counter-jib, can realize revolution.For the implementation platform lifting, trailer wagon (11) must be moved to jib (10) root And hangs over suspension hook (12) on the column (8), one group of coaster (14) is housed on the wire rope in addition, when carrying out hoisting operation, coaster (14) hangs on the stock (5), when lift platform (4), then coaster (14) is suspended on the derrick guide rail (3).During lifting platform, security insurance pin (6) relies on the effect of inclined-plane and spring, withdraws automatically and stretches out, and realizes location and insurance.In the time will descending platform, move security insurance pin (6) to retracted position by a joystick (13), platform (4) just can descend smoothly.

After finishing the finishing work in the workspace, unload the standard knot of derrick guide rail (3) with lifting gear, pack up the revolution supporting leg, can move another workspace to underframe (1) to manpower and carry out work again.If use several so dual-purpose platforms simultaneously, just can build large-area building below five layers.

Fig. 2 has represented the fall line route of hoist rope: wire rope is drawn from the reel of lifting mechanism (2), enter into tackle pulley (14) through the fixed pulley (15) that is contained on the underframe (1), be incorporated into the movable pulley (16) that is contained on the stock (5) by tackle pulley (14), return tackle pulley (14), enter the fixed pulley (17) that is contained in column (8) lower end again, guide to the pulley (18) that is contained in revolving body (9) top then, be directed to the pulley (19) that is contained on the revolving body (9) downwards, horizontal direction is directed to the pulley (20) on the trailer wagon (11) again, be directed to pulley (21) on the suspension hook (12) by (20), turn back to another pulley (20) on the dolly (11) again, be fixed on the end of jib (10) at last.Tackle pulley (14) has two hooks, and when carrying out lifting operation, (14) hang on the stock (5), and when carrying out the lift platform operation, (14) hang over again on the derrick guide rail (3).The frame plate of pulley (18) can be around the rotation of O point, and the general work situation is hung downwards, when jib (10) is installed, it is moved to position shown in the dotted line, so that promote and rise and pull jib.

Fig. 3 has represented the mechanism principle of security insurance pin: when lift platform (4) rises to certain position, trundle on the security insurance pin (6) can be run into the wedge piece (23) that is contained on the derrick guide rail (3), make spring (22) compression, security insurance pin (6) withdrawal.In case arrive wedge piece (23) end face, spring (22) can eject safety plug (6) again, rides over wedge piece (23) end face, supports lift platform (4), and it can not be fallen down.When lift platform was descended, joystick (13) turned right one to be pushed away, and by leverage, just can move retracted position to security insurance pin (6) to, and lift platform (4) just can descend smoothly.

Fig. 4 represents that column (8) works the process of pulling: pulley (18) is coupled together by hoist rope with jigger (24), jigger (24) is tied up on the derrick guide rail (3) again, and lifting mechanism just can be cocked next column.

Fig. 5 represents to lift by crane the process of jib (10): pulley (18) is supported, and it is suspention jigger (24) down, (24) and jib (10) root is coupled together again, and lifting mechanism just can be sling jib (10) root come.After putting in place, arm root and revolving body (9) are coupled together with bearing pin.

Fig. 6 represents that jib (10) rises and pulls process: jigger (24) is connected with drag-line (25), adorn a short drag-line (26) at revolving body (9) top, by lifting mechanism, just can be cocked next jib, the other end of jigger (24) is connected with drag-line (26), jib has just installed again.

Compare with prior art, the utility model can be with finishing platform and crane functions combination, both improved the lifting altitude of crane, simplified the required auxiliary equipment of loading and unloading derrick again, total in addition cheap and saving mounting cost, be applicable to very much 3～5 one storey buildings, the building operations of particularly numerous small towns dwelling house.
