The utility model discloses an install the hoisting mechanism on the hoist and play to rise wire rope and will become a motor and transport on amplitude changing device and between the ground, realized the change that becomes width of cloth motor, not only saved the manpower, improved the security moreover, shortened the change time, improved change efficiency.

Description

A kind of derrick crane changes luffing electric machine
Technical field
The utility model is related to a kind of derrick crane to change luffing electric machine, belongs to derrick crane technical field.
Background technology
As depicted in figs. 1 and 2, pulley bracket is not provided with existing derrick crane, is become when being used to drive on jib lubbing mechanism 1 There is the failure that cannot repair, it is necessary to during dismounting and change in the luffing motor 5 of the work of width mechanism 1, because dolly 3 cannot be in crane arm Run on 2, so luffing motor 5 can not be transported on ground from tower crane using suspension hook 4 being changed, can only be incited somebody to action using manpower The luffing motor of failure is sent to ground after pulling down, then new luffing motor manpower is transported at jib lubbing mechanism, can complete to become The replacing of width motor, complex operation, inefficiency.And, each luffing motor weighs about 100 kilograms, and manpower is transported easily to be occurred Accident, safety coefficient is low.
The content of the invention
For the problem that above-mentioned prior art is present, the utility model provides a kind of derrick crane and changes luffing motor dress Put, it is possible to provide change the security and high efficiency of luffing motor.
To achieve these goals, a kind of derrick crane that the utility model is used changes luffing electric machine, including Lifting mechanism, hoist rope on crane and the pulley yoke on crane arm, the one of hoist rope End is wrapped on lifting mechanism, and the other end is fixedly connected through pulley yoke with the luffing motor on jib lubbing mechanism, by lifting mechanism Luffing motor is transported to ground with hoist rope, the replacing of luffing motor is realized.
Preferably, the pulley yoke includes fixed support and the pulley on fixed support, and fixed support includes U-shaped Installing plate and the connecting plate being fixed on below U-shaped installing plate, pulley are arranged on U-shaped installing plate, and pulley yoke is pacified by connecting plate On crane arm.
Preferably, the luffing motor is provided with suspension ring, and the end of hoist rope is provided with and hanging that suspension ring are used cooperatively Hook, suspension hook catches on the connection that suspension ring realize hoist rope and luffing motor.
Preferably, the pulley yoke is arranged on crane arm by bolt.
Compared with prior art, the utility model will be become by the lifting mechanism and hoist rope on crane Width motor is transported on jib lubbing mechanism and ground between, realizes the replacing of luffing motor.Needed when luffing motor breaks down During replacing, lifting mechanism work can be started, discharge hoist rope, the failure luffing motor on jib lubbing mechanism is transported to ground Face.Failure luffing motor is removed, and by new luffing motor connection in the end of hoist rope.It is to be connected finish after, control Lifting mechanism reclaims hoist rope, and new luffing motor is promoted on jib lubbing mechanism by ground, realizes luffing motor more Change.Whole Renewal process utilizes lifting mechanism, not only saves manpower, and improves security, shortens replacing construction, carries Replacing efficiency high.

Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figures 3 to 6, a kind of derrick crane changes luffing electric machine, including rising on crane Mechanism 7, hoist rope 8 and the pulley yoke on crane arm 26 are risen, the one ends wound of hoist rope 8 is in lifting machine On structure 7, the other end is fixedly connected through pulley yoke 6 with the luffing motor 5 on jib lubbing mechanism 1, by lifting mechanism 7 and raising steel wire Luffing motor 5 is transported to ground by rope 8, realizes the replacing of luffing motor 5.
As shown in Figure 5 and Figure 6, when luffing motor 5 breaks down to be needed to change, lifting mechanism 7 can be started and is worked, discharged Hoist rope 8, ground is transported to by the failure luffing motor 5 on jib lubbing mechanism 1.Failure luffing motor 5 is removed, and will be new Luffing motor connection is in the end of hoist rope 8.It is to be connected finish after, control lifting mechanism 7 reclaim hoist rope 8, will New luffing motor 5 is promoted on jib lubbing mechanism 1 by ground, realizes the replacing of luffing motor.
Preferably, the pulley yoke 6 includes fixed support and the pulley on fixed support, and fixed support includes U Type installing plate and the connecting plate being fixed on below U-shaped installing plate, pulley are arranged on U-shaped installing plate, and pulley yoke 6 passes through connecting plate On crane arm 2.The simple structure of this pulley yoke 6, low cost.
Preferably, the luffing motor 5 is provided with suspension ring, and the end of hoist rope 8 is provided with and is used cooperatively with suspension ring Suspension hook, suspension hook catches on the connection that suspension ring realize hoist rope 8 and luffing motor 5.Suspension ring, the cooperation of suspension hook ensure luffing motor 5 stability in lifting process, it is to avoid situation about coming off occurs, and further increases the security of replacing.
Preferably, the pulley yoke 6 is arranged on crane arm 2 by bolt, and pulley yoke 6 is detachable, and convenient transportation is quick.
From said structure, the present invention is electric by luffing by the lifting mechanism and hoist rope on crane Machine is transported on jib lubbing mechanism and ground between, realizes the replacing of luffing motor, not only saves manpower, and improve peace Quan Xing, shortens replacing construction, improves replacing efficiency.
