Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a pier fence construction platform device. Background Art

[0002] The high piers of railway bridges are designed with hanging fences as inspection platforms during the later operation period. When constructing the pier fence, a fence operation platform needs to be erected for workers and equipment to construct the pier fence. Usually, scaffolds or car crane hanging frames are used for pier fence construction. Scaffolds are erected around as the operation platform for installing the hanging fence. This method requires multiple transfers of the platform, which is time-consuming and laborious; while using a car crane hanging frame to hoist workers for operation, the construction speed is slow, greatly restricted by the surrounding environment of the pier, with a low safety factor and high resource consumption.

[0003] Therefore, a pier fence construction platform device that can solve the above problems is needed. Summary of the Invention

[0004] The purpose of the utility model is to provide a pier fence construction platform device according to the deficiencies of the above-mentioned prior art. The device consists of a platform mechanism and a hoisting device. The hoisting device is installed on the top of the pier, and the hoisting device is connected to the platform mechanism and drives the platform mechanism to move along the height direction of the pier to achieve the rapid construction of the pier fence.

[0005] The purpose of the utility model is achieved by the following technical solutions:

[0006] A pier fence construction platform device includes a platform mechanism and a hoisting device. The platform mechanism is annular, and a through hole allowing the pier to pass through is provided in the middle of the platform mechanism. An anti-collision ring is provided at the edge of the through hole. The hoisting device is installed on the top of the pier. The hoisting device is connected to the platform mechanism and drives the platform mechanism to move along the height direction of the pier. The hoisting device includes a winch, a steel wire rope, and a fixed pulley. The winch is installed on the top of the pier. The fixed pulley is arranged outside the top of the pier and above the platform mechanism. One end of the steel wire rope is connected to the winch, and the other end is wound around the fixed pulley and connected to the platform mechanism.

[0007] Both the fixed pulley and the winch are arranged on a fixing plate. One side of the fixing plate is fixed on the top of the pier, and the other side extends to the outside of the top of the pier.

[0008] A removable guardrail is arranged in a circle along the outer circumference of the platform mechanism.

[0009] Eight hoisting devices are arranged in a ring along the top of the pier, and two hoisting devices are arranged on the front side, rear side, left side, and right side of the top of the pier respectively.

[0010] The advantages of the utility model are as follows: simple, convenient and safe, improving the safety factor of the installation of the high pier hanging fence, facilitating the construction of workers, having reliable edge protection, and being able to greatly ensure the safety of construction personnel, which is worthy of popularization.

[0013] Figure 3 It is a schematic diagram of the hoisting device of the utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] The features of the utility model and other related features will be further described in detail below with reference to the drawings through embodiments for the understanding of those skilled in the same industry:

[0015] As Figures 1 to 3 shown, the marks in the figure are respectively represented as:

[0016] Platform mechanism 1, through hole 2, anti-collision ring 3, winch 4, steel wire rope 5, fixed pulley 6, fixing plate 7, detachable guardrail 8, pier 9.

[0017] Embodiment: As Figures 1 to 3 shown, this embodiment relates to a pier fence construction platform device, which mainly includes a platform mechanism 1 and a hoisting device. The platform mechanism 1 is annular, and a through hole 2 allowing the pier 9 to pass through is provided in the middle of the platform mechanism 1, and an anti-collision ring 3 is provided at the edge of the through hole 2. The anti-collision ring 3 is made of a rubber ring, which can prevent collision between the platform mechanism 1 and the pier 9. A circle of detachable guardrails 8 is arranged along the outer circumference of the platform mechanism 1, and the detachable guardrails 8 play a protective role for the construction personnel on the platform mechanism 1, improving the safety of the pier fence construction process. The hoisting device is installed on the top of the pier 9, and the hoisting device is connected to the platform mechanism 1 and drives the platform mechanism 1 to move along the height direction of the pier 9 for installing the pier fence.

[0018] As Figures 1 to 3As shown in the figure, there are eight lifting devices arranged circumferentially along the top of pier 9, with two lifting devices arranged on the front side, rear side, left side, and right side of the top of pier 9 respectively, making the force on the platform mechanism 1 more uniform during the lifting process, making it not easy for the platform mechanism 1 to swing, and improving the safety of the construction process. The lifting device includes a winch 4, a steel wire rope 5, and a fixed pulley 6. The winch 4 is installed on the top of pier 9, the fixed pulley 6 is arranged outside the top of pier 9 and above the platform mechanism 1. One end of the steel wire rope 5 is connected to the winch 4, and the other end is wound around the fixed pulley 6 and connected to the platform mechanism 1. The winch 4 retracts the steel wire rope 5, thereby realizing the movement of the platform mechanism 1 along the height direction of pier 9. Among them, both the fixed pulley 6 and the winch 4 are arranged on the fixed plate 7. One side of the fixed plate 7 is fixed on the top of pier 9, and the other side extends to the outside of the top of pier 9, with reliable connection.
