After various buildings such as houses or bridges are operated for a long time, or the outer vertical faces of the buildings need to be checked and maintained for clearing potential safety hazards, or the outer vertical faces of the buildings need to be coated and decorated for landscape lifting, hanging baskets are usually adopted for construction, and a proper suspension device needs to be arranged at the top of the buildings for hanging basket construction. Some traditional suspension devices adopt rail-type or wheel-mounted suspension devices, the volume of the suspension devices is large, the arrangement of the suspension devices is often interfered by other auxiliary facilities on the top of a building, and the problems of high outdoor maintenance cost, short service life, high manufacturing cost and the like exist; and part of the suspension devices are in a clamp type or counterweight suspension type, and the suspension devices cannot adjust the cantilever length extending out of the building due to the fact that the suspension devices cannot stretch out and retract, are exposed outside the building when not in work, are difficult to maintain and influence the landscape of the building. Therefore, it is necessary to develop a suspension device that can satisfy the requirements of light weight, convenient operation, reasonable cost, low later maintenance cost, no influence on building landscape, etc.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a flexible linkage, it enables the adjustable hoisting point of device during operation and stretches out the length of building in order to adapt to the size that the lifting rope hung in midair the object, and non-during operation retractable building is inside in order to reduce the influence to the building view.

In order to achieve the above purpose, the technical solution of the present invention is as follows: a telescopic suspension device is characterized by comprising a fixed support and a telescopic support which are fixed on a building, wherein the telescopic support penetrates through the fixed support, and the extending length is adjusted through a telescopic control mechanism; the end part of the telescopic support is provided with a front end lifting lug, and a lifting rope is hung at the front end of the telescopic support through the front end lifting lug and used for hanging a hanging basket or an operation platform; the tail of the telescopic support is provided with a rear end lifting lug, and the hanging balance weight is hung on the tail of the telescopic support through the rear end lifting lug.

Furthermore, the fixed support is connected with the connecting base through a pin shaft, and the connecting base is fixed on the top surface of a building through an anchor bolt.

Furthermore, the front end of the telescopic support is provided with a front end limit stop block, and the tail of the telescopic support is provided with a rear end limit stop block.

Furthermore, a guide roller for guiding the telescopic bracket to stretch is arranged in the fixed bracket.

Furthermore, the bottom of telescopic bracket is equipped with the spur rack, flexible control mechanism include with spur rack complex gear unit and be used for driving the motor of gear unit, motor drive gear unit rotates, and the drive spur rack drives telescopic bracket and stretches out and draws back.

Furthermore, the lifting lug at the front end of the telescopic support is provided with two lug holes, and two lifting ropes can be installed.

Furthermore, the hanging counterweight adopts a standard modulus mass block, and the specification and the number of the mass block can be adjusted according to the lifting weight of the front end lifting rope.

The beneficial effects of the utility model reside in that:

1) the suspension device has small volume, small influence on the arrangement of auxiliary facilities at the top of the building and small maintenance workload.

2) The hanging device can adjust the length of the building to adapt to the size of the object hung by the lifting rope during working, and can be retracted into the building during non-working, thereby having little influence on the building landscape.

3) The hanging counterweight adopts a standard modulus mass block, and the lifting capacity of the front end lifting rope can be adjusted by adjusting the specification and the number of the hanging counterweights.

4) The front end lug of telescopic bracket is equipped with two earholes, can hang work rope and safety rope simultaneously to the security of preventing falling is improved.
