Abstract

The utility model relates to a building tower crane hoisting device, namely a tower crane attached mounting-demounting hoisting device. The device comprises a lifting cantilever fixed on a balance arm on one side of a tower crane, wherein a left pulley spindle and a right pulley spindle transversely placed are arranged at the outer end of the lifting cantilever extending outside, and the outer ends of the left and the right pulleys are provided with pulleys which are corresponding to a left pulley and a right pulley fixedly arranged on the balance arm; and a hoisting winch is arranged on the balance arm, and a steel wire rope on the hoisting winch is fixed on the balance arm after penetrating the right pulley of the balance arm, the pulley on the right pulley spindle, a lifting hook, the pulley on the left pulley spindle and the left pulley of the balance arm. The device is reserved on a balance arm on the other side of the tower crane, mainly used for lifting and fixing pull rods when a tower body of the tower crane is stably fixed, and also can be used for assisting lifting. When the tower body of the tower crane is stably fixed, the device can mechanically lift heavier pull rods so as to avoid using ordinary hemp ropes to lift the pull rods, and the device can fix the tower body safely and fast.

Description

Tower crane adheres to peace and tears lifting appliance open

Technical field

The utility model relates to a kind of tower crane lifting appliance for building, and promptly tower crane adheres to peace and tears lifting appliance open.

Background technology

In the prior art, the construction machinery equipment tower crane is made up of tower body and left and right equilibrium arm.After tower crane frame was set to certain altitude, tower body will be captiveed joint with the building that build on the next door by at least two above auxiliary connecting rods usually, to increase stability.Because pull bar is heavier, install and fix pull bar under the equilibrium arm of suspension hook and can mention having by the tower crane suspension hook, but the pull bar installation in opposite side equilibrium arm bottom needs manually use the rope pull-up, install and fix, often rupture in the practical operation because of rope, pull bar falls from eminence, has hidden danger.

The utility model content

The purpose of this utility model is to provide a kind of at above-mentioned deficiency to set up lifting appliance at tower crane equilibrium arm opposite side, is used to make things convenient for the tower crane of steady brace to adhere to peace and tears lifting appliance open.

Technical solution of the present utility model is: tower crane adheres to peace to be torn lifting appliance open and comprises the cantilever that hoists that is fixed on the tower crane one lateral balance arm, and there is horizontal left and right sheave shaft at the place, outer end that leans out of the cantilever that hoists, and there is pulley left and right sheave shaft axle outer end; Be fixed with the left and right pulley of equilibrium arm on the corresponding equilibrium arm of left and right sheave shaft top sheave; Equilibrium arm is provided with winch, fixes behind steel wire penetrating equilibrium arm right pulley, right pulley axle top sheave, suspension hook, left chain wheel axle top sheave and the equilibrium arm left chain wheel with on the equilibrium arm on it.This device is standby on tower crane opposite side equilibrium arm, and lifting steady brace usefulness also can be made service hoisting when being mainly used in tower crane tower body held stationary.

The utility model has the advantages that: during tower crane tower body held stationary, can realize the pull bar that mechanical lifting is heavier, avoid using the common rope made of hemp to play suspending bars, realization safety, quick tower body are fixed.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.

Description of drawings

Fig. 1 is the tower crane structure diagram.

Fig. 2 is the utility model structure diagram.

The specific embodiment

Referring to Fig. 1, tower crane is made up of tower body 1 and left and right equilibrium arm 2,3.Tower body is captiveed joint with the building that build on the next door by pull bar 4,5, to increase stability.Pull bar 5 can be sling by the suspension hook under the right equilibrium arm 3 and install and fix, and pull bar 4 can adhere to peace by the tower crane on the left equilibrium arm 2 and tear lifting appliance 6 open and sling and install and fix.

Referring to Fig. 2, tower crane adheres to peace to be torn lifting appliance 6 open and comprises the cantilever 7 that hoists that is fixed on the left equilibrium arm 2, and there is horizontal left and right sheave shaft 8,9 at the place, outer end that leans out of the cantilever 7 that hoists, and there is pulley 10,11 8,9 outer ends of left and right sheave shaft; Be fixed with the left and right pulley 12,13 of equilibrium arm on left and right sheave shaft 8,9 top sheaves 10, the 11 corresponding left equilibrium arms 2; Left side equilibrium arm 2 is provided with winch 14, and steel rope 15 passes on equilibrium arm right pulley 13, right pulley axle top sheave 11, suspension hook 16, left chain wheel axle top sheave 10 and equilibrium arm left chain wheel 12 backs and the left equilibrium arm 2 fixing on it.In the tower crane operator's compartment, start winch 14, realize suspension hook 16 liftings, be used for suspending bars.The cantilever 7 that hoists can be fixed on left equilibrium arm 2 in the left, right, front and rear adjustment, to satisfy on-the-spot actual needs.
