Technical Field

The utility model relates to a hanging apparatus installed on the roof of a building, in particular to an improved supporting frame structure of a folding and unfolding type hanging device.

Background

The outer walls of buildings such as houses and buildings are mostly constructed by cement, tiles, metal, nonmetal, glass and the like, and are affected by ambient air, dust and rain for a long time, so that maintenance work such as cleaning, repairing and the like needs to be carried out regularly to ensure the cleanliness and weather resistance of the outer walls of the buildings.

It is known that, in the maintenance work of cleaning and repairing the outer walls of buildings at present, a cable is mostly used to suspend a maintenance platform or a wall washer and the like vertically lifted between the outer walls of each floor by using a hanging device installed on the roof of the building. Wherein, the maintenance platform can be used for wall washing workers or maintenance personnel to stand so as to facilitate the work of cleaning or repairing the outer wall; the wall washer can perform rolling washing operation on the wall surface by virtue of the automatic brushing wheel attached to the wall washer. In addition, for example, between each floor of the building, the cable can be hung down to the ground by using the hanging device arranged on the roof, and then the heavy object can be hung to the window hole of the required floor, so as to be convenient for carrying the heavy object.

Moreover, since the hanging device is required to be carried to the roof of the building, supported by the parapet wall extending from the floor of the roof, and horizontally moved on the floor of the roof, so as to change the horizontal position of the hung object (such as a maintenance platform, a wall washer or other heavy objects) on the outer wall, the hanging device is generally made into a movable type; however, the conventional hanging device technology is not easy to expand and collect although it can be moved, and the process of carrying the hanging device to the roof by using a vehicle and the limited elevator space of a building is very arduous and difficult.

For example, taiwan patent nos. M444373 and M507929 disclose hanging structures of L-shaped frames, respectively, and are generally composed of a movable carrier with a vertical support and a horizontal support with a retractable length mounted thereon. The L-shaped frame bodies of the hanging structures are all in a locking type by screws and the like, have large volume and are not beneficial to disassembly and transportation; and the effect that its horizontal stand can expand and contract is limited to the distance that control hawser, water pipe and electric wire expansion extended to the parapet outward, to reducing the volume of suspended structure when above-mentioned on-vehicle transport and ladder transport to help not wantonly.

Wherein:

the load-carrying box 20 can be made of a metal box shell with an accommodating space therein; one side of the load box 20 is provided with a box door 21 which can open and close the accommodating space in the box; the bottom of the load-carrying box 20 is provided with a plurality of corner wheels 22, the corner wheels 22 are commercially available products and are formed by combining a retractable wheel body in a rubber or metal foot pad; when the load box 20 needs to be moved, the wheels in the foot pads can be released to contact the ground, so as to move the load box 20 to the position to be installed on the roof ground 10; when the load-carrying box 20 needs to be fixed, the wheel body is retracted to make the foot pad contact the roof ground 10, so that the load-carrying box 20 can be stably arranged at the required position of the roof ground 10. The weight-balancing weight 70 such as a weight or a discus can be attached to the inner part or the outer walls of both sides of the load-carrying box 20 as required to increase the immovable stability of the load-carrying box 20 when the load-carrying box 20 is vertically placed on the top floor 10, so that the load-carrying box 20 can be used as a foundation pile for erecting the suspension arm 30 on the top floor 10.

The control unit 23 is disposed in the receiving space of the load-carrying box 20, and a motor 24 and a power line spool 25 for winding and unwinding a cable 25a are installed. The control unit 23 controls the forward and reverse rotation and the rotation speed of the motor 24, and drives the power line coil 25 to rotate through the connection of a belt or a chain to release and retrieve the cable 25a for hanging heavy objects.

The boom 30 is formed by mutually sleeving a plurality of foldable frames 31, 32, 33, which can be divided into a large frame 31, a middle frame 32 and a small frame 33, all of which can be made into a hollow rectangular channel frame shape, and the mutual sleeving can be used for realizing the operation of unfolding and retracting, so that an operator can easily change the total length of the boom 30. Wherein, a plurality of bolt holes 34 can be arranged at equal intervals at the connecting end parts of the frames 31, 32 and 33 which are mutually penetrated and sleeved; when the required length of the boom 30 is changed by extending each frame 31, 32, 33, the bolt holes 34 between the two frames are aligned and sleeved, and a pin 35 is respectively sleeved, thereby fixing each extended frame 31, 32, 33, preventing the frames 31, 32, 33 from sliding each other when the boom 30 is loaded, and facilitating the operator to remove the pin 35 and fold the boom 30.

Furthermore, a pivot hole 36 is formed at one end of the large frame 31 of the suspension arm 30, a removable shaft bolt 37 can be used to penetrate through the pivot hole 36 of the suspension arm 30 at a position near the bottom of the front end of the load box 20, so as to connect the suspension arm 30 and the load box 20 into a whole, and the suspension arm 30 can be pivoted to adjust the inclined angle of the suspension arm through the pivot of the shaft bolt 37 and the pivot hole 36. Further, after the frames 31, 32, 33 are stretched to obtain the desired stretching length of the boom 30, the boom 30 can be obliquely bridged between the load box 20 and the supporting frame 40, and a triangular supporting structure a (as shown in fig. 2) is constructed among the stretched boom 30, the roof floor 10 and the supporting frame 40; the connection between the boom 30 and the load box 20 by the removable shaft bolt 37 is helpful to improve the convenience of disassembling and assembling between the boom 30 and the load box 20.

In practical implementation, at least one pulley 33a can be pivoted at the end of the small frame 33 in the boom 30, so that the cable 25a on the power wire coil 25 can be pulled by the boom 30 placed above the roof ground 10 through the extending and inclining frame and guided by the pulley 33a, and a weight W hung on the outer wall of the building can be lifted vertically. The triangular support structure A can sufficiently disperse stress when a load W is hung on the boom 30, and prevent stress concentration between members of the device.
