Problems solved by technology

[0002] During the construction of roads and bridges, it is often necessary to build engineering ladders for the maintenance and care of high piers of roads and bridges. Due to the different heights of high piers of roads and bridges, the existing engineering ladders are straight ladders or herringbone ladders with fixed heights and can only be replaced with different heights. To meet the requirements of maintenance and care at different heights, it is inconvenient to use, time-consuming and laborious, and sometimes it is necessary to perform maintenance and maintenance at multiple positions at the same height. The existing engineering ladders need to be adjusted up and down repeatedly, which is inconvenient to use and construction Repeated up and down of personnel increases the risk of personnel construction

Embodiment 2

[0058] Further, a gap 18 is provided between the front side and the bottom surface of the second horizontal plate 3, a horizontal round rod 19 is arranged in the gap 18, and at least one elastic clip is provided on the rear side of the second horizontal plate 3 , the elastic clip is detachably connected with the horizontal round rod 19 .

[0059] In the present invention, through the detachable connection between the elastic clip and the horizontal round rod 19, the angle between the two in-line ladders of the gabled ladder can be changed, and at the same time, the connection of the second horizontal plate 3 on the upper part is maintained, which is more stable and convenient to use. .

[0060] In order to avoid people standing on the horizontal one-word ladder, it is easy to step on the air and cause a high-altitude fall, such as Figure 5 and Image 6 As shown, further, the left and right sides of the plurality of first horizontal plates 2 are provided with rotating shafts...

Embodiment 1

[0074] The present invention can realize the upper and lower connection of two in-line ladders through a plurality of first limiting grooves and a first connecting column, and at the same time, through a plurality of second connecting columns and telescopic connecting pieces, the stability between the side surfaces of the upper and lower in-line ladders can be realized. Connect, change the height of the one-word ladder according to the needs, easy to use, such as figure 1 and figure 2 shown.

[0075] Example 2

[0076] In the present invention, the upper part of the two one-way ladders are approached, the bottom part is separated, and the two-way ladder can be formed by a plurality of second connecting columns and telescopic connecting pieces on the side, such as image 3 The height of the ladder can be changed, and the use is convenient.

Embodiment 3

[0078] In the present invention, three in-line ladders can be combined to form a stable π-shaped ladder through the second limiting groove and a plurality of first connecting columns on the top of the second horizontal plate, as well as the second connecting columns and telescopic connecting pieces on the side of the vertical rod. type ladder, such as Figure 4 As shown, it can meet the needs of workers to perform maintenance and care at multiple positions at the same height, without frequent up and down, easy to use, and at the same time reduce construction risks.

[0079] The invention can change the angle between the two ladders of the zigzag ladder through the detachable connection between the elastic clip and the horizontal round rod, while maintaining the upper part connection, which is more stable and convenient to use.

[0080] The rotating shaft of the invention enables the first horizontal plate to rotate, and the first horizontal plate can be positioned through the ...

Abstract

The invention relates to the technical field of auxiliary tools for road and bridge construction, and discloses a multifunctional combined ladder for road and bridge construction, which comprises two vertical rods with rectangular cross sections; the first transverse plates are arranged between the two vertical rods; two ends of the two transverse plates are fixedly arranged at the tops of the two vertical rods; a plurality of first limiting grooves are formed in the front side faces of the two vertical rods in the height direction. A plurality of first connecting columns corresponding to the first limiting grooves are arranged on the rear side faces of the two vertical rods in the height direction, and second limiting grooves are formed in the two sides of the top of the second transverse plate correspondingly. A plurality of second connecting columns are arranged on the left side face and the right side face of each vertical rod in the height direction, telescopic connecting pieces are hinged to the second connecting columns, a linear ladder with the adjustable height can be achieved through simple assembly, a herringbone ladder can be formed, a pi-shaped ladder can also be assembled, workers can conduct maintenance and nursing at multiple positions of the same height, and the working efficiency is improved. The use is convenient.

Description

technical field [0001] The invention relates to the technical field of auxiliary tools for road and bridge construction, in particular to a multifunctional combined ladder for road and bridge construction. Background technique [0002] During the construction of roads and bridges, it is often necessary to build engineering ladders for the maintenance and care of the high piers of the roads and bridges. Due to the different heights of the high piers of the roads and bridges, the existing engineering ladders are in-line ladders or herringbone ladders. The height is fixed and can only be replaced with different heights. It is inconvenient to use, time-consuming and laborious, and sometimes needs to be repaired and maintained at multiple positions at the same height. The existing engineering ladder needs to be adjusted up and down repeatedly, which is inconvenient to use, and the construction The repeated up and down of personnel increases the risk of personnel construction.
