Cantilever crane device suitable for dismantling external scaffold of assembled high-rise residence

Technical Field

The utility model relates to a cantilever bearing specifically is a cantilever hoist and mount device suitable for assembly type high-rise residence external scaffolding demolishs in the hoist field on the stand.

Background

The assembled building is because single component weight is big, often adopt the heavy tower crane that lifting capacity is strong, the expense of corresponding tower crane rent also can be higher, after the major structure construction finishes, the tower crane does not have work basically and can develop, but can not demolish, secondary structure such as traditional construction meeting and outer decoration finishing back, demolish outer scaffold frame by the tower crane again, demolish the tower crane at last, in the time of waiting for demolising outer scaffold frame, the tower crane is idle for 3 ~ 4 months usually, this will cause very big fund waste for the construction unit.

SUMMERY OF THE UTILITY MODEL

In order to overcome prior art's defect, provide one kind and build convenience, flexible operation, operation efficient hoisting accessory, the utility model discloses a cantilever crane device suitable for assembly type high-rise residence exterior scaffold demolishs.

The utility model discloses a following technical scheme reaches the invention purpose:

the utility model provides a cantilever hoist and mount is put suitable for outer scaffold frame of assembled high-rise residence is demolishd, includes the landing leg, characterized by: also comprises a balancing weight, a counterweight frame, a winch, a track, a pillar and a stay cable,

the bottom of landing leg is fixed perpendicularly on lifting by crane the platform, and the top at the landing leg is fixed horizontally to the below at track middle part, and the bottom of pillar is fixed perpendicularly in the top at track middle part, and orbital both ends are tied respectively to the both ends of suspension cable, and the middle part of suspension cable is around the top at the pillar, and the fixed counter weight frame in below of track one end, the bottom of counter weight frame is placed on lifting by crane the platform, is equipped with the balancing weight in the counter weight frame, and orbital other end is movably equipped with the hoist engine.

The cantilever crane device suitable for dismantling the assembled high-rise residential building external scaffold is characterized in that: the landing leg is for connecting the falling Y type that the bottom dispersed constitutes with the top by two spinal branch vaulting poles, and H shaped steel is chooseed for use to the counter weight frame, and the I-steel is chooseed for use to the track and is equipped with the suspension cable.

The utility model discloses to the idle problem design of tower crane behind the assembled high-rise building major structure capping, each system all can be dismantled into single spare part, is convenient for ann and tears open, and the flexible operation can carry out the high efficiency to the outer scaffold and demolish, has avoided heavy tower crane to wait to demolish the rent loss during the outer scaffold after finishing.

1. The hoisting system adopts a monorail crane winch with a corresponding specification and model according to the total height and the hoisting weight of the building and is responsible for hoisting a heavy object;

2. the cantilever frame body adopts I-shaped steel as a hoisting track, and is assisted by a steel wire rope inclined-pulling type frame body and a movable supporting leg as a support of a hoisting system.

3. The counter weight adopts precast concrete block, for U type plane, installs in the support body afterbody, prevents that the support body from toppling during the operation.

The utility model discloses following beneficial effect has:

scaffold members are generally lighter, and the performance of the tower crane cannot be fully exerted by adopting the tower crane to dismantle, so that resource waste is caused. The utility model discloses replaced the construction method that traditional tower crane demolishd outer scaffold, can be used to console mode scaffold, demolishs such as the scaffold of encorbelmenting, makes the tower crane demolish in advance, has practiced thrift equipment resource, has reduced construction cost. The device also can be used for hoisting small materials and components, and can solve the problem of construction in a range which can not be covered by part of tower cranes.

The utility model discloses all adopt the bolted connection equipment, the resolvable component that becomes scattered can be accomplished by the manpower, need not other equipment assistance, and easy to assemble dismantles. The problems that a tower crane is idle and an outer scaffold is dismantled in the fabricated building are solved, and the fabricated building has great advantages in the field of fabricated building construction.

Detailed Description

The invention is further illustrated by the following specific examples.

Example 1

The utility model provides a cantilever crane device suitable for assembled high-rise residence external scaffolding demolishs, includes balancing weight 1, counter weight frame 2, hoist engine 3, track 4, pillar 5, suspension cable 6 and landing leg 7, as shown in fig. 1 and fig. 2, concrete structure is:

the bottom of landing leg 7 is fixed perpendicularly on lifting by crane platform 8, the top at landing leg 7 is fixed horizontally to the below at track 4 middle part, the bottom of pillar 5 is fixed perpendicularly in the top at track 4 middle part, the both ends of track 4 are tied respectively to the both ends of suspension cable 6, the middle part of suspension cable 6 is around the top of pillar 5, the fixed weight carrier 2 in below of track 4 one end, the bottom of weight carrier 2 is located on lifting by crane platform 8, be equipped with balancing weight 1 in the weight carrier 2, the movably hoist engine 3 that is equipped with of orbital other end.

In this embodiment: the landing leg 7 is connected the falling Y type that the bottom dispersed and constitute with the top by two spinal branch vaulting poles, and H shaped steel is chooseed for use to the counter weight frame 2, and the I-steel is equipped with the suspension cable for use to the track 4.

This embodiment is to the idle problem design of tower crane behind the assembled high-rise building major structure capping, and each system all can be dismantled into single spare part, is convenient for ann and tears open, and the flexible operation can carry out the high efficiency to demolish to outer scaffold, has avoided heavy tower crane to wait to demolish the rent loss of removing during outer scaffold after finishing.
