[0021] The following is combined with Figures 1 to 3 This utility model will be described in detail.

[0022] A detachable pier cage structure includes a pier 1, a cage 2 on one side of the pier 1, a connecting rod 201 on one side of the cage 2, a movable platform 202 connected to one side of the cage 2, a hinge shaft 2021 connected to one end of the movable platform 202, the movable platform 202 being connected to the cage 2 via the hinge shaft 2021, traction cables 2022 on both sides of the end of the movable platform 202 away from the hinge shaft 2021, a winder 2023 on one side of the middle of the cage 2, a pin 2024 connected to one side of the winder 2023, and a support assembly connected to the bottom of the movable platform 202.

[0023] First, when constructing the pier 1, a ladder cage 2 will be built on one side of the pier 1 so that construction workers can walk up and down in the ladder cage 2 to reach the high part of the pier 1 for construction. At the same time, a connecting rod 201 will be set on one side of the ladder cage 2 to connect with the pier 1 to ensure the stability of the ladder cage 2.

[0024] Furthermore, the top edge of the activity platform 202 is equipped with a guardrail, and the winders 2023 are arranged in two vertically. The traction cable 2022 passes through the upper winder 2023 and is wound and connected to the lower winder 2023. The winder 2023 is wound and connected to the traction cable 2022 through a centrally rotating roller. The pin 2024 passes through a disc on one side of the winder 2023 and connects to one side of the central roller. One end of the central roller of the winder 2023 is provided with several holes that cooperate with the pin 2024, and one end of the central roller of the winder 2023 is connected to a crank through the winder 2023.

[0025] When it is necessary to dismantle the ladder cage 2, the connecting rod 201 and the pier 1 must be removed first. First, the pin 2024 is removed from one side of the winding device 2023. Then, the roller in the winding device 2023 that winds the connecting traction cable 2022 can be rotated to release the traction cable 2022. When the traction cable 2022 is released, the movable platform 202 will deflect along the hinge axis 2021 until it is parallel, so that a movable platform is formed between the ladder cage 2 and the pier 1, so as to facilitate contact with the connecting rod 201 between the ladder cage 2 and the pier 1, thereby facilitating its dismantling.

[0026] Furthermore, the support assembly includes a support rod 203, a hinge block 2031, and a telescopic rod 2032. The support rod 203 is hinged to the bottom of the movable platform 202, the hinge block 2031 is hinged to the end of the support rod 203 away from the movable platform 202, the telescopic rod 2032 is located in the middle of the support rod 203, and one side of the hinge block 2031 is fixedly connected to the ladder cage 2. The support rod 203 is divided into two parts, and the two parts of the support rod 203 are connected together by the telescopic rod 2032.

[0027] Simultaneously, when the movable platform 202 deflects outward, it will cause the bottom support rod 203 to retract, allowing the support rod 203 to shorten via the telescopic rod 2032 to cooperate with the deflection of the movable platform 202. Both ends of the support rod 203 are hinged to the movable platform 202 and the hinge block 2031 respectively, allowing the support rod 203 to follow the deflection of the movable platform 202. When the movable platform 202 deflects to a parallel state, the telescopic rod 2032 will also abut against the bottom of the groove on the inner wall of the support rod 203, preventing the support rod 203 from further retracting. This provides support to the bottom of the movable platform 202, making the movable platform 202 more stable after deflection. When the movable platform 202 is being stored, the telescopic rod 2032 is pulled out to facilitate the retraction of the deflection.

[0028] The following is a detailed implementation process of this utility model. First, when constructing the pier 1, a ladder cage 2 is built on one side of the pier 1 for construction workers to walk up and down in the ladder cage 2 to reach the higher parts of the pier 1 for construction. At the same time, a connecting rod 201 is also set on one side of the ladder cage 2 to connect with the pier 1 to ensure the stability of the ladder cage 2. When it is necessary to dismantle the ladder cage 2, the connecting rod 201 needs to be removed from the pier 1 first. First, the pin 2024 is taken out from one side of the winding device 2023. Then, the roller in the winding device 2023 that winds the connecting traction cable 2022 can be rotated to release the traction cable 2022. When the traction cable 2022 is released, the movable platform 202 will deflect along the hinge axis 2021 until it is in a parallel state, so that a movable platform is formed between the ladder cage 2 and the pier 1, so as to facilitate contact with the connecting rod 201 between the ladder cage 2 and the pier 1, thereby facilitating its dismantling.

[0029] Simultaneously, when the movable platform 202 deflects outward, it will cause the bottom support rod 203 to retract, allowing the support rod 203 to shorten via the telescopic rod 2032 to cooperate with the deflection of the movable platform 202. Both ends of the support rod 203 are hinged to the movable platform 202 and the hinge block 2031 respectively, allowing the support rod 203 to follow the deflection of the movable platform 202. When the movable platform 202 deflects to a parallel state, the telescopic rod 2032 will also abut against the bottom of the groove on the inner wall of the support rod 203, preventing the support rod 203 from further retracting. This provides support to the bottom of the movable platform 202, making the movable platform 202 more stable after deflection. When the movable platform 202 is being stored, the telescopic rod 2032 is pulled out to facilitate the retraction of the deflection.
