Abstract

The utility model discloses a top slewing tower crane erected by equipment of itself. The tower crane takes advantage of self lifting mechanism as the unique power equipment of erecting (or dismounting) to the carry out the complete machine erecting (or dismounting) of a non-integral lifting plate form, which need not be provided with an auxiliary crane and an auxiliary hoist. So the installing (or dismounting) expenses of the tower crane can be reduced when the tower crane is applied, which is particularly suitable for construction of buildings of middle or small urban residential areas or narrow places. Besides, the manufacturing cost of the tower crane is lower than that of the existing low-level slewing tower crane adopting an integral lifting plate form.

Description

Top slewing tower crane erected by equipment of itself
The utility model is about tower crane (hereinafter to be referred as the tower machine), the top slewing tower machine that particularly relies on equipment of itself to set up.This tower machine is equipped with one in a side of body of the tower and can climbs along body of the tower the erecting frame of (or decline), and a mounting bracket respectively is housed on cat head and equilibrium arm, relies on the lifting mechanism of tower machine self, can carry out the whole installations or the demolition of complete machine.
It generally is to be undertaken by auxiliary hoist (car hosit etc.) or auxiliary winch that the installation of top slewing tower machine is at present set up.And this installation method need spend more erected cost; Also have a kind of known dependence tower machine equipment of itself and structure to adopt whole the installation method of pulling, but this installation method, to the higher erection stress of relevant parts generation of tower machine, the equipment manufacturing cost height, and only can be used for the little tower machine of lifting altitude.
Task of the present utility model provides and a kind ofly relies on equipment of itself, complete machine to set up but be not the whole top slewing tower crane that plays plate.
Solution of the present utility model: adorn a mounting bracket directly over equilibrium arm afterbody, counterbalanced weight installation site, the equilibrium arm root is adorned a pulley (or assembly pulley), and the crane arm root is adorned a pulley (or assembly pulley).In addition, also need one can be contained in body of the tower one side, along body of the tower climb (or decline) erecting frame and on cat head, adorn a demountable mounting bracket.
Just can finish the installation of body of the tower by erecting frame and tower machine self, the lifting mechanism that is contained on the equilibrium arm like this, just can lift by crane equilibrium arm by the lifting mechanism of mounting bracket on the cat head and tower machine self and the pulley of equilibrium arm root to cat head.Utilize the mounting bracket on the equilibrium arm afterbody, the lifting mechanism and the mounting bracket on the cat head of tower machine self just can play plate to equilibrium arm again.Demountable mounting bracket on the cat head is installed to the opposite side of cat head, utilize it and the lifting mechanism of tower machine self and the pulley of crane arm root just crane arm can be lifted by crane.Utilize the pulley on lifting mechanism, the mounting bracket on the cat head and the crane arm pull bar of tower machine self just crane arm can be played plate again.At last, lifting mechanism and the mounting bracket on the cat head by the mounting bracket on the equilibrium arm, tower machine self install to counterbalanced weight on the equilibrium arm, so just can finish the installation of whole tower machine.
Accompanying drawing has been described embodiment of the present utility model.
Accompanying drawing 1: the top slewing tower pusher side view that relies on equipment of itself to set up.
Fig. 2 has described the installation situation of body of the tower to cat head, with bolt underframe (11) is fastened on the concrete pedestal (12), with anchor ear (14) erecting frame (15) is fastened on underframe (11) (or body of the tower (10)) side, the lifting mechanism (3) of tower machine self is gone up steel rope by the pulley on the underframe (13) spaced winding tackle block (16) on the erecting frame top in erecting frame (15), and the lifting mechanism (3) that starts tower machine self can install to ground body of the tower (10) on the underframe (or body of the tower).
Fig. 3 has described the situation of erecting frame (15) rising (or decline), whenever after installing joint (or some joints) body of the tower standard knot, earlier below the erecting frame bottom pulley (17), steel rope above the pulley on the underframe (13) is suspended to snatch block (18) and goes up (lifting mechanism (3) of the steel rope other end and tower machine self links to each other), again snatch block is suspended to body of the tower top, install two anchor ears (14) on erecting frame mobile jib top then, shed two anchor ears of the original dress in erecting frame mobile jib bottom, and the hook of the tackle block on the erecting frame (16), be suspended on the erecting frame mobile jib bottom hook (19), the lifting mechanism (3) that starts tower machine self can promote erecting frame (15), after lifting finishes, erecting frame both sides hooks (20) are suspended on the new body of the tower standard knot, guarantee erecting frame work.
Fig. 4 has described equilibrium arm lifting situation, and the steel rope on the lifting mechanism is walked around equilibrium arm root pulley (21), and around the mounting bracket (22) on cat head (6), the lifting mechanism (3) that starts tower machine self can lift by crane equilibrium arm.
Fig. 5 has described equilibrium arm (5) and has played the plate situation, steel rope on the lifting mechanism (3) of tower machine self is walked around mounting bracket (22) on the cat head (6) around the mounting bracket on equilibrium arm (2), start the lifting mechanism (3) of tower machine self, equilibrium arm can be played plate, install equilibrium arm drag-line (4), equilibrium arm just installs.
Fig. 6 has described the lifting situation of crane arm, steel rope on the lifting mechanism (3) of tower machine self is walked around the mounting bracket (22) on the cat head (6), around the pulley (23) on crane arm (8) root, start the lifting mechanism (3) of tower machine self, crane arm can be lifted by crane.
Fig. 7 has described the plate situation that rises of crane arm, steel rope on the lifting mechanism (3) of tower machine self is walked around the mounting bracket (22) on the cat head (6), around the pulley (7) on crane arm pull bar (9), start the lifting mechanism (3) of tower machine self, crane arm can be played plate, install crane arm pull bar (9), crane arm installs.
Fig. 8 has described the situation of lifting counterbalanced weight, steel rope on the lifting mechanism (3) of tower machine self is walked around mounting bracket (22) on the cat head (6) and the mounting bracket (2) on the equilibrium arm (5), around to gin wheel (24), suspension hook under the gin wheel (25) hangs up properly counterbalanced weight (1), start the lifting mechanism (3) of tower machine self, counterbalanced weight can be winched on the equilibrium arm.
The lifting mechanism of the utility model utilization itself is as the power that (demolition) is installed, and need not to join Put auxiliary hoist or hoist engine, can reduce mounting cost, and with low cost, be particularly suitable for Small Urban or construction site and use when narrow.
