Detailed Description

The present invention will be further described with reference to the following specific examples, but the scope of the present invention is not limited to the following examples.

Example 1

According to the hanging basket shown in the figure, a bottom longitudinal beam 1 is suspended by steel strands, lower cross beams 2 are arranged at two ends below the bottom longitudinal beam 1, one bottom longitudinal beam 1 is matched with two lower cross beams 2, and the two lower cross beams 2 are fastened with the lower ends of steel strands 13 respectively to support and limit the bottom longitudinal beam 1, which is the existing structure of a triangular hanging basket.

A lower operating platform for hanging baskets is disclosed, as shown in figures 1-3, and comprises a pedestrian passageway 32, a railing 31 is vertically fixed on one side of the pedestrian passageway 32, and a hanging part bent downwards is connected on the other side of the pedestrian passageway 32; during the flying piece can match and insert a string basket bottom end rail 2, bottom end rail 2 is formed by two parallel I-steel connections, and the middle space that leaves, during the installation, lower operation platform 3 generally installs the side of keeping away from end rail 1 at the bottom end rail 2 of the bottom end rail 2 that lies in the inboard, and the flying piece inserts in the space between these two parallel I-steel of bottom end rail 2 promptly, makes lower operation platform 3 can fix at bottom end rail 2 side to realize that operating personnel can construct at the roof beam side.

The walkway 32 is formed by several steel plates connected together by a floor web 34, the number of plates being selected according to the actual situation and may be 2 or more.

Further, the hanging member includes a protection portion 36, horizontal connection portions 35 and vertical hanging portions 37, the protection portion 36 is vertically fixed on one side of the pedestrian passageway 32, the lower end of the protection portion is connected with the pedestrian passageway 32 through a bottom plate connection plate 34, the horizontal connection portions 35 are arranged in parallel, one end of each horizontal connection portion is connected with the upper end of the protection portion 36, the other end of each horizontal connection portion is connected with the upper end of the vertical hanging portion 37, as shown in fig. 3 and 4, the vertical hanging portion 37 is a component inserted into the lower beam 2 during installation, and the protection portion 36 and the vertical hanging portion 37 are generally made of long steel plates or i-shaped steel.

Furthermore, the pedestrian passageway 32 is made of a patterned steel plate, and the patterned steel plate has larger friction force relative to the I-shaped steel used by the upper cross beam and can play a good anti-skidding role.

Example 2

This embodiment has substantially the same structure as embodiment 1, and additionally, a collar 39 and a guide rod 38 are added to better ensure the convenience and stability of suspension.

As shown in fig. 5 and 6, the two horizontal connecting portions 35 at the outermost ends are connected with collars 39 at the outer sides, the collars 36 are matched with guide rods 38, and the guide rods 38 are matched and fixed on the upper surface of the lower cross beam 2 of the cradle. Generally, the guide rods 38 are welded on the lower beam 2 in advance according to the distance of the collars 39, and when the lower operation platform is installed, as shown in fig. 4, the lower operation platform is hung to the side of the lower beam 2, the guide rods 38 can play a guiding role, the collars 36 are sleeved on the outer sides of the guide rods 38, the vertical hanging parts 37 are inserted into the lower beam 2 in a matching mode, and the lower operation platform 3 is installed to a proper position. The collar 36 has an internal dimension greater than the external dimension of the guide rod to facilitate installation due to difficulties in aerial installation. Because the lantern ring 39 designs too much, probably because the convenience of whole installation is influenced to the counterpoint problem with guide bar 38, consequently, the utility model discloses set up lantern ring 39 in the outside of horizontal joint portion 35, can both obtain the fixed action of lantern ring 39 and guide bar 38 under the messenger on the whole length of operation platform 3, of course, also can suitably adjust the mounted position of lantern ring 39 and guide bar 38 according to the circumstances.

Preferably, the lower platform 3 may be inclined outwardly due to the weight of the operator, and to better prevent this, the side of the collar 39 remote from the walkway 32 is higher than the side close to the walkway 32. The lower operating platform 3 does not flip outwards due to the blocking action of the guide rods 38 against the collar 36.

More preferably, the height of the side of the collar 39 far away from the pedestrian passageway 32 is equal to the height of the guide rod 38 or less than the height of the guide rod 38 by no more than 5cm, so that the contact area is increased, and the stability of the lower operating platform 3 can be better ensured.

More preferably, the guide rod 38 is in a shape with a small upper end and a large lower end, the upper end is a smooth arc surface, the small upper end and the large lower end enable the lantern ring 36 to be better sleeved outside the guide rod 38, and the possibility of injury to operators during construction can be reduced due to the arc surface.

More preferably, in order to better fix the guide rod 38 and the collar 39 together and prevent the guide rod 38 and the collar 39 from shifting easily, the guide rod 38 and the collar 39 are provided with screw holes in a matching manner, the screw holes are matched with the bolts 30 to pass through to fix the guide rod 38 and the collar 39 together, and the lower operating platform 3 can be better prevented from turning outwards or moving leftwards and rightwards through the fixing effect of the bolts 30. Generally, the screw hole is provided at a side away from the walkway 32, i.e. a high side, to facilitate the installation of the bolt 30 from the walkway 32.

It should be particularly emphasized that the lower operation platform of the present embodiment may be mounted on a cradle, such as a truss cradle, a prismatic cradle, and a cable-stayed cradle, in addition to the triangular cradle shown in fig. 4.
