Description

Interlayer crane

Technical Field

The utility model relates to a loop wheel machine, especially an interlaminar loop wheel machine.

Background

In the decoration construction of the outer wall of a building, a curtain wall framework (less than 500kg) is often required to be directly hoisted to an installation position and installed by an installer.

At present, the hoisting is carried out by adopting a track and a single-arm crane or adopting a tower crane and other modes. However, when the curtain wall is hoisted by adopting the track and the single-arm crane, the defects of inconvenient erection, installation and dismantling, incapability of flexibly moving, incapability of adapting to hoisting of various unit curtain wall frameworks, large use limitation and high cost exist; when the existing tower crane is used for hoisting in a construction site, the defects of high hoisting cost and low efficiency exist.

In order to solve the problems, a hoisting trolley for a unit curtain wall framework appears in the field, such as the following patent numbers: CN201410475777.3, the hoisting trolley for the unit curtain wall framework comprises a saddle, and a suspension arm and a winch which are arranged on the saddle; the front end of the saddle is provided with an anchoring screw, the rear end of the saddle is provided with a balancing weight, and the bottom of the saddle is provided with a plurality of universal wheels; the suspension arm is obliquely arranged, the rear end of the suspension arm is arranged on the saddle, and the front end of the suspension arm is provided with a lifting wheel.

During operation, the hoisting trolley can be placed between layers, the vehicle seat is pushed to a working position, the universal wheels are braked, the anchoring screw is screwed down, the whole body is fixed, the forward tilting is avoided, the winch drives the sling to lift, and the sling is kept to move in the vertical direction by the rope stabilizing rod to conduct hoisting operation.

However, in subsequent use, operating personnel discovers that because this type of crane mainly relies on the universal wheel to make the crane move as a whole, can't finely tune the distance between by the hanging object to the curtain skeleton mounted position for accurate hoist and mount of curtain skeleton to the mounted position need curtain skeleton installer to stimulate the curtain skeleton to realize the fine setting, this potential safety hazard that can greatly increased installer.

In order to solve the problems, the interlayer crane imitating a tower crane in the field comprises a crane boom and a balance arm which is fixedly arranged relative to the crane boom, wherein a counterweight and a winch are fixedly arranged on the balance arm, a steel wire rope on the winch penetrates through a trolley and then is connected with a sling and drives the sling to lift, a trolley traction mechanism is arranged on the crane boom, and the trolley traction mechanism drives the trolley to slide along the direction of the crane boom through the steel wire rope so as to adjust the distance between a suspended object and a mounting position of a curtain wall framework.

In subsequent use, an operator finds that the hoist drives the lifting appliance to rise and fall through the steel wire rope, when the lifting appliance lifts a lifted object, the steel wire rope connected with the lifting appliance can be completely straightened, so that the vertical fine adjustment positioning of the curtain wall framework is not influenced, however, the hoist mainly depends on a trolley traction mechanism to drive a trolley to slide on a lifting arm along the direction of the lifting arm through the steel wire rope so as to adjust the distance between the lifted object and the installation position of the curtain wall framework, the steel wire rope connected with the trolley is horizontally arranged, because the steel wire rope has the flexible deformation characteristic, when the steel wire rope is horizontally arranged, the hoisting appliance can not be completely straightened, the hoisting appliance can not be horizontally and accurately pulled, the curtain wall framework is difficult to be horizontally finely adjusted to a preset position, meanwhile, because the hoist and the lifting arm are relatively fixedly arranged, when the hoist does not work, but the trolley moves, the lifting appliance can, when the trolley moves, the hoist is required to drive the lifting appliance to lift so as to eliminate the influence of the trolley movement on the height position of the lifting appliance, and the defects of complex process of fine adjustment of the position of the curtain wall framework and high fine adjustment cost exist.

Meanwhile, because a plurality of supporting columns are arranged on the part, close to the outer wall, between the floors of the building, the use of the existing floor crane is often limited by the supporting columns.

Therefore, in view of the above, there is a need for a crane that can solve the above problems.
