[0002] The bridge deck waterproofing system is an important system in the construction process of highway bridges. The quality of the bridge deck waterproofing system determines the durability of the bridge to a certain extent. In order to extend the service life and durability of highway bridges, it is necessary to strictly control the installation of bridge deck drain pipes.

[0003] At present, aerial work platforms or mobile high-altitude working platforms are usually used in the installation of bridge drainage pipes. The cost of aerial work machines is high, and the safety risk is high when the traffic volume under the bridge is large. The cost of using mobile high-altitude working platforms is lower than that of aerial work platforms, but they occupy a large area and are not easy to reach the drainage pipe installation site under the bridge, making the construction process inconvenient.

[0004] When the bridge is a double-column pier cantilever cap beam, the installation area of ​​the double-column pier cantilever cap beam is limited, and traffic diversion is required to meet the construction conditions. Therefore, a aerial platform cannot be used. At the same time, it is not easy to reach the installation position of the drain pipe on the inner side of the side beam using a mobile high-altitude working platform, making the installation of the bridge drain pipe difficult.

[0005] In summary, the installation of the drain pipe of the cantilever cap beam of the double-column pier cannot be done by a aerial platform due to the limited installation area, and the mobile high-altitude working platform cannot easily reach the installation position of the drain pipe on the inner side of the side beam, making the installation of the bridge drain pipe difficult. Utility Model Content

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A drainage pipe high-altitude working platform is arranged on an anti-collision guardrail, comprising: a platform frame, comprising a horizontal section and a vertical section, the vertical section is fixedly connected to one end of the horizontal section; a safety rope hanging rod, arranged on the horizontal section, the safety rope hanging rod is used to connect the safety rope; a ladder, one end of the ladder is fixedly connected to the other end of the horizontal section, the ladder and the platform frame form a hook-shaped integrated structure, and the other end of the ladder is fixedly connected to the working platform to form an integrated structure; the working platform; pulleys, the number of pulleys is at least three groups, two groups of pulleys are respectively arranged on the horizontal section and the vertical section, and the remaining group of pulleys is arranged on the ladder, and the three groups of pulleys are respectively in rolling contact with both sides and the top of the anti-collision guardrail.

[0009] As a preferred embodiment, guardrails are provided around the working platform.

[0010] As a preferred embodiment, a triangular support is provided between the horizontal section and the vertical section, and a triangular support is provided between the horizontal section and the ladder.

[0011] As a preferred embodiment, a drainage pipe high altitude working platform also includes a latch, which is plug-in connected to the pulley, and the latch is used to fix the pulley.

[0012] As a preferred embodiment, the horizontal section and the vertical section are perpendicular to each other, the ladder and the horizontal section are perpendicular to each other, the vertical section and the ladder are parallel to each other, and the vertical section and the ladder are arranged opposite to each other.

[0013] As a preferred embodiment, the working platform is located directly below the anti-collision guardrail.

[0014] In general, the utility model has the following advantages:

[0015] The utility model discloses a drainage pipe high-altitude operation construction platform that hangs the entire operation platform on the anti-collision guardrail by using a hook. The entire operation platform has a low production cost, is light and easy to load and unload, and has a high safety factor, and does not require the use of other machinery for high-altitude operations. Since the entire operation platform is hung on the anti-collision guardrail, a large installation space is not required. Moreover, since the entire operation platform is hung on the anti-collision guardrail, the operation platform is directly below the anti-collision guardrail, that is, on the inside of the side beam, the drainage pipe can be directly installed on the inside of the side beam.

[0020] The present invention will be further described in detail below in conjunction with specific implementation methods.

[0021] like Figure 1 As shown, a drainage pipe high-altitude working platform provided in this embodiment includes a platform frame 5, a safety rope hanging rod 6, a ladder 7, a working platform 8, a plug 3, a triangular support 4, a guardrail 9 and a pulley 10. The ladder 7, the safety rope hanging rod 6 and the triangular support 4 are fixed on the platform frame 5 by welding, and the pulley 10 is welded to each part of the platform frame 5 and the ladder 7. The working platform 8 is connected through the ladder 7, and the guardrail 9 is installed around the working platform 8 to ensure that the surroundings are tightly sealed during the construction process. Specifically, the platform frame includes a horizontal section and a vertical section that are perpendicular to each other, and the vertical section is fixedly connected to one end of the horizontal section; the safety rope hanging rod is set on the horizontal section, one end of the ladder is fixedly connected to the other end of the horizontal section, the ladder and the platform frame form a hook-shaped integrated structure, and the other end of the ladder is fixedly connected to the working platform to form an integrated structure; thereby forming a drainage pipe high-altitude working platform into an integral structure. The number of pulleys 10 is at least three groups. In this embodiment, the number of pulleys 10 is taken as three groups, wherein at least two groups of pulleys are respectively arranged in the horizontal section and the vertical section, at least one group of pulleys is arranged in the ladder, and the three groups of pulleys are respectively in rolling contact with the two sides and the top of the anti-collision guardrail. The setting of the triangular brace is as follows: a triangular brace is arranged between the horizontal section and the vertical section, and a triangular brace is arranged between the horizontal section and the ladder. In addition, it should be noted that when the entire drain pipe high-altitude working platform is hung on the anti-collision guardrail, the working platform is located directly below the anti-collision guardrail, so that the center of gravity of the whole and the center of gravity of the anti-collision guardrail are in the same vertical plane.

[0022] The construction process of the drainage pipe high-altitude operation construction platform of this embodiment is as follows: first, the platform frame 5 and the various parts of the drainage pipe high-altitude operation platform are connected on the ground by welding and bolts to form an integrated assembled platform. During installation, workers can manually carry it to the anti-collision guardrail (or they can be lifted to the anti-collision guardrail by a crane), and adjust the position of the pulley 10 to be close to the anti-collision guardrail. During construction, the workers first fix the safety rope on the safety rope hanging rod 6, and then climb the ladder 7 to the operation platform 8 for construction. During the operation, the workers install the plug 3 at the pulley 10 to fix the entire operation platform. When the workers need to transfer the construction point after the construction is completed, the plug 3 is taken out and the entire drainage pipe high-altitude operation construction platform is moved to the next construction point through the pulley 10. When the workers complete the construction and leave the drainage pipe high-altitude operation construction platform, the pulley 10 position can be adjusted to be out of contact with the anti-collision guardrail, and the platform is moved upward to be out of contact with the anti-collision guardrail.

[0023] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
