[0016] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings of the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the scope of protection of the utility model.

[0017] Please refer to Figs. 1-3 In the embodiments of the utility model, a fence structure of bridge construction basket, including bottom plate 1, the top of bottom plate 1 is installed with fence mechanism, and the fence mechanism includes guardrail 2 located at the center of the top end of bottom plate 1 one side, the inner side of guardrail 2 is rotatably installed with rotating door 3, and the bottom end of bottom plate 1 is installed with automatic locking mechanism below rotating door 3, and the back end of rotating door 3 is installed with prevent outside open mechanism.

[0018] In the embodiment: when the basket has not been lifted and located on the ground, the automatic locking mechanism does not lock the rotating door 3 at this time, the staff opens the rotating door 3 inwards by pushing, after the staff enters the basket, the rotating door 3 is closed, after the rotating door 3 is closed, it can only be reset to the initial position, and the prevent outside open mechanism can prevent the rotating door 3 from continuing to open outward;

[0019] When the basket is moved upward by the cooperation of the hoisting device after the rotating door 3 is closed, the bottom plate 1 is gradually separated from the ground, at this time, the automatic locking mechanism is automatically locked and limited to the rotating door 3 under the action of gravity, at this time, the rotating door 3 cannot be opened, and the workers in the basket are not easy to accidentally touch the unlocking device, so as to cause the rotating door 3 to be opened by mistake.

[0020] Please refer to Fig. 2 , the anti-out mechanism comprises a fixed piece 7 fixedly connected to the back end of the rotating door 3, the inner wall of the fixed piece 7 is in interference fit with a horizontal rod 8, one end of the horizontal rod 8 protrudes outward along the length direction of the rotating door 3 and is in contact with the back end of the protective fence 2.

[0021] In this embodiment: when the rotating door 3 is turned from the inward opening state to the closed state, the horizontal rod 8 moves synchronously with the rotating door 3 through the fixed piece 7 until the rotating door 3 drives the horizontal rod 8 to be in contact with the back end of the protective fence 2, at this time, the rotating door 3 cannot continue to rotate outward, and the rotating door 3 and the automatic locking mechanism are kept in alignment in the vertical direction;

[0022] It should be noted that: the back end of the protective fence 2 is in contact with the horizontal rod 8, and a magnet is embedded in the contact position, and the horizontal rod 8 is made of iron material, which can effectively prevent the rebound phenomenon of the rotating door 3 caused by the collision with the protective fence 2 during the closing process.

[0023] Please refer to Fig. 2 and Fig. 3 , the automatic locking mechanism comprises a containing groove 4 opened in the inside of the bottom plate 1 and located below the rotating door 3, the inner side wall of the containing groove 4 is fixedly connected with an outward protruding connecting shaft 6, the outer wall of the connecting shaft 6 is rotatably connected with a rotating arm assembly 5, and the automatic locking mechanism further comprises a clamping groove 9 opened in the bottom end of the rotating door 3, and the vertical section of the clamping groove 9 is in a fan-shaped structure.

[0024] In this embodiment: when the basket is raised, the bottom plate 1 is gradually separated from the ground, under the action of gravity, the rotating arm assembly 5 rotates around the connecting shaft 6 as the center, one end of the rotating rotating arm assembly 5 is clamped into the clamping groove 9, at this time, the rotating door 3 is limited, and since the rotating arm is located below, the rotating door 3 will not be unlocked due to accidental touch of the automatic locking mechanism during the construction of the workers;

[0025] When the construction is completed, the basket slowly descends until the bottom plate 1 is in contact with the ground, at this time, one end of the rotating arm assembly 5 in the inclined state is in contact with the ground, the ground applies a pressing force to one end of the rotating arm assembly 5, so as to reset the rotating arm assembly 5, at this time, the rotating arm assembly 5 is separated from the clamping groove 9, and the rotating door 3 can be opened.

[0026] Please refer to Fig. 3The rotating arm assembly 5 is composed of a first rotating plate 10 and a second rotating plate 11, the center position of the first rotating plate 10 and the second rotating plate 11 connected with the connecting shaft 6 is rotatably connected, and the density of the first rotating plate 10 is greater than that of the second rotating plate 11.

[0027] In the embodiment, since the force arm length of the first rotating plate 10 and the second rotating plate 11 is equal, when the basket rises, the first rotating plate 10 rotates downward from the horizontal state, and the second rotating plate 11 rotates upward from the horizontal state, the upward rotating second rotating plate 11 is clamped into the clamping groove 9, and the limiting of the rotating door 3 is completed.

[0028] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
