Abstract
The invention discloses a hoisting machine of a crane, and belongs to hoisting equipment. The invention provides a hoisting machine which causes hoisting material to keep balance due to the same hosting force of hosting rods during hoisting process. The technical scheme thereof is completed in a way that the hoisting machine of the crane comprises two corresponding hoisting systems arranged on the same hosting beam; each hoisting system comprises a hosting machine, a pulley group and hoisting rods, wherein, the two corresponding hoisting systems share a wire rope (4); the wire rope (4) which is arranged above the hoisting machine (3) in the hoisting system is connected to the windlass (7) of the hoisting system (6) through a pulley group (2), a guiding pulley (1), a guiding pulley (9) and a pulley group (8). The invention is applied to a crane.
Description
Technical field:
The present invention relates to the machine that hoists on a kind of hoisting crane, particularly a kind of machine that hoists that can make lifting thing protection balance.
Background technology:
At present, the machine of hoisting on the same hanging beam includes two corresponding hoisting systems, each hoisting system is made up of winch, assembly pulley, a suspension rod, each uses steel cable each hoisting system, respectively there is one to play suspension rod, unequal phenomenon takes place in two corresponding hoisting systems lifting force in the lifting process easily, makes the lifting thing be not easy to keep balance.
Summary of the invention:
The present invention provides and plays in a kind of lifting process that suspension rod is stressed to be equated, makes the lifting thing keep the machine that hoists of balance.Technical scheme of the present invention is finished like this, the machine that hoists on the hoisting crane, it comprises and is located at two corresponding hoisting systems on the same hanging beam, each hoisting system is made up of winch, assembly pulley, a suspension rod, two shared steel cables 4 of corresponding hoisting system, the steel rope 4 on the winch 3 in the hoisting system 5 is connected on the winch 7 of hoisting system 6 through assembly pulley 2, leading sheave 1, leading sheave 9, assembly pulley 8.Because two are played the shared steel cables of suspension rod, thus two lifting forces that rise on the suspension rod equate, can make the lifting thing keep balance.
Description of drawings:
Fig. 1 twines scheme drawing for the steel rope of two hoisting systems of the present invention;
Fig. 2 twines scheme drawing for the steel rope of four hoisting systems of the present invention;
Drawing explanation: 1, leading sheave; 2, assembly pulley; 3, winch; 4, steel rope; 5, hoisting system; 6, hoisting system; 7, winch; 8, assembly pulley; 9, leading sheave; 10, play suspension rod; 11, play suspension rod; 12, hoisting system; 13, hoisting system; 14, hoisting system; 15, play suspension rod; 16, play suspension rod; 17, hoisting system.
The specific embodiment:
Shown in Fig. 1 be, the machine that hoists on the hanging beam is made up of hoisting system 5 and corresponding hoisting system 6, each hoisting system all has the suspension rod that rises separately, and the steel rope 4 on the winch 3 in the hoisting system 5 is on assembly pulley 2, leading sheave 1, leading sheave 9, assembly pulley 8 are connected to winch 7 on the hoisting system 6.Because hoisting system 5 and hoisting system 6 shared steel cables 4 are equal so play suspension rod 10 and play the lifting force of suspension rod 11 when lifting, can make the lifting thing keep balance in the lifting process.
Shown in Fig. 2 be, on same hanging beam, be provided with two corresponding machines that hoist, each machine that hoists has two hoisting systems side by side, the corresponding hoisting system 13 shared steel cables of hoisting system 12 with it, hoisting system 14 hoisting system 17 shared steel cables corresponding with it, two machines that hoist all have the suspension rod that rises of controlling oneself; Because hoisting system 12 and hoisting system 13 shared steel cables are so hoisting system 12 and the lifting force of hoisting system 13 in the lifting process equate; The also shared steel cable of hoisting system 14 and hoisting system 17, so hoisting system 14 and the lifting force of hoisting system 17 in the lifting process also equate, so the lifting force that plays suspension rod 15 on the machine that hoists that plays suspension rod 16 and is made up of hoisting system 17 and hoisting system 14 on the machine of being made up of hoisting system 12 and hoisting system 17 that hoists also equates, can make and lift by crane thing and in the lifting process, keep balance.
Claims (1)
1, the machine that hoists on the hoisting crane, it comprises and is located at two corresponding hoisting systems on the same hanging beam, each hoisting system is made up of winch, assembly pulley, a suspension rod, it is characterized in that: two shared steel cables of corresponding hoisting system (4), the steel rope (4) on the winch (3) in the hoisting system (5) is connected on the winch (7) of hoisting system (6) through assembly pulley (2), leading sheave (1), leading sheave (9), assembly pulley (8).
