Technical Field

[0001] The utility model relates to the field of high - speed railway pier construction, and particularly relates to a platform for the construction of the hanging fence of a pier. Background Technique

[0002] During the laying of high - speed railway tracks, due to topographical reasons, it is often necessary to build bridges for track laying. The bridges are supported by piers constructed by pouring. In flat areas, a hanging basket vehicle is used to hoist a construction platform for the construction of the hanging fence of the pier.

[0003] However, in valley areas with large topographical changes, affected by the large changes in the terrain of the construction section, the moving space of the crane boom of the traditional hanging basket vehicle is limited, and it is difficult to reach some hanging fence positions of the pier, resulting in difficult construction of the hanging fence. Especially when the hanging basket vehicle moves and adjusts its position in a potholed area, it is easy to cause the construction platform to shake, making it difficult to ensure the safety of the operators; currently, although there is a circular construction platform set outside the pier, the circular construction platform is fixed by welding, which has problems such as inconvenient transportation and difficulty in adapting to the construction of piers of different sizes. Moreover, when the circular construction platform is in use, it depends on a crane to suspend the platform, which has safety risks. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies in the inconvenient use and potential safety hazards of the existing circular construction platform, and to provide a platform for the construction of the hanging fence of a pier.

A passage is provided in the middle of the circular platform, and the bridge pier can pass through the passage, so that the operators can carry out the construction of the suspension fence around the outer wall of the bridge pier on the circular platform; the rectangular plates are connected through the connecting parts. According to the size of the bridge pier, the adjacent rectangular plates are connected through the connecting parts at different positions to adjust the size of the passage, so as to reduce the distance between the rectangular plates and the bridge pier, facilitating the operators to carry out the construction of the suspension fence; the traction assembly is arranged at the top of the bridge pier to improve the safety of the circular platform; the circular platform can be fixed at a predetermined height through the traction assembly; the traction assembly is connected to the rectangular plates on the opposite sides of the circular platform, so that the circular platform can maintain a balanced state in the air, ensuring the construction safety of the operators; the rectangular plates abut against the outer wall of the bridge pier, thereby stabilizing the circular platform.

[0010] Preferably, along the length direction of the rectangular plate, a plurality of the connecting parts are arranged in a row.

[0011] Connecting the adjacent rectangular plates through the connecting parts at different positions can adjust the size of the passage, enabling the rectangular plates to abut against the outer wall of the bridge pier, so that the circular platform can be adapted to bridge piers of different sizes; the connecting parts are arranged along the length direction of the rectangular plate, making the adjustment range of the passage larger and enabling it to adapt to more bridge piers of different sizes.

[0012] Preferably, along the width direction of the rectangular plate, at least two rows of the connecting parts are provided in the connecting section.

[0014] Preferably, the connecting part includes a through hole. The through holes located in different rectangular plates can be aligned and communicated, and the adjacent rectangular plates are connected by bolts.

[0015] Adopting the method of setting bolts in the through holes to connect the adjacent rectangular plates ensures the firmness of the connection; the bolt connection method is easy to disassemble and adjust, ensuring that the operators can quickly adjust the passage of the circular platform to a suitable size.

[0016] Preferably, the traction assembly includes a bottom plate, a first traction motor and a second traction motor. The first traction motor and the second traction motor are respectively connected to the bottom plate. The first traction motor is connected to the rectangular plates on the opposite sides of the circular platform through two first traction ropes respectively.

[0020] Preferably, the bottom plate includes a first clamping member and a second clamping member. The two ends of the first clamping member are respectively connected with the second clamping member to form an H-shaped structural member, and the first clamping member and the second clamping member are respectively clamped and connected with the pier.

[0045] The traction assembly 2 is connected to at least the rectangular plate bodies 11 on opposite sides of the rectangular platform 1, and the traction assembly 2 is used to connect to the top of the pier 4.

[0046] A passage is provided in the middle of the rectangular platform 1, and the pier 4 can pass through the passage, so that operators can construct the hanging fence 3 around the outer wall of the pier 4 on the rectangular platform 1; the rectangular plate bodies 11 are connected through the connecting parts 5, and according to the size of the pier 4, adjacent rectangular plate bodies 11 are connected through the connecting parts 5 at different positions to adjust the size of the passage, so as to reduce the distance between the rectangular plate bodies 11 and the pier 4, facilitating the operators to construct the hanging fence 3; the traction assembly 2 is arranged on the top of the pier 4 to improve the safety of the rectangular platform 1; the rectangular platform 1 can be fixed at a predetermined height through the traction assembly 2; the traction assembly 2 connects the rectangular plate bodies 11 on opposite sides of the rectangular platform 1, so that the rectangular platform 1 can maintain a balanced state in the air, ensuring the construction safety of the operators; the rectangular plate bodies 11 abut against the outer wall of the pier 4, thereby stabilizing the rectangular platform 1; the rectangular plate bodies 11 are disassembled to reduce the volume, which is convenient for transportation.

[0047] In one or several embodiments, along the length direction of the rectangular plate body 11, ten connecting parts 5 are arranged in a row; the connecting parts 5 are through holes, and the through holes located on different rectangular plate bodies 11 can be aligned and communicated, and adjacent rectangular plate bodies 11 are perpendicular to each other after being connected by bolts; the distance between any two adjacent through holes in the same row is equal.

[0048] In an optional embodiment, the number of through holes arranged in the same row is more than ten.

[0049] In an optional embodiment, two rows of through holes are arranged in the connection interval. When connecting adjacent rectangular plate bodies 11, four through holes can be aligned and communicated at the same time, making the connection between the rectangular plate bodies 11 more stable by bolts.

[0050] In one or more embodiments, the traction assembly 2 includes a bottom plate 21, a first traction motor 22, and a second traction motor 23. The first traction motor 22 and the second traction motor 23 are respectively connected to the bottom plate 21. The first traction motor 22 and the second traction motor 23 are both arranged on the top of the bottom plate 21. The first traction motor 22 is connected to the rectangular plate bodies 11 on the opposite sides of the loop-shaped platform 1 through two first traction ropes. By rotating the first traction motor 22, the first traction motor 22 can lift or lower two relatively arranged rectangular plate bodies 11 at the same time. The second traction motor 23 is connected to the rectangular plate bodies 11 on the opposite sides of the loop-shaped platform 1 through two second traction ropes.

The U-shaped structural member can respectively abut against the opposite sides of the pier 4 to achieve clamping, making it difficult for the H-shaped structural member to have longitudinal displacement. The rectangular block structural members are clamped in the grooves at the top of the pier 4, making it difficult for the H-shaped structural member to have lateral displacement, thereby realizing the limitation of the bottom plate 21.

[0053] In an alternative embodiment, the towing rope is detachably connected to the rectangular plate body 11.

[0054] In one or several embodiments, the rectangular plate body 11 is provided with a fence 3, and the fence 3 is connected to the side of the rectangular plate body 11 away from the pier 4. By providing the fence 3, it is possible to prevent the operators from falling from the loop platform 1 and ensure the safety of the operators.
