Freely movable construction platform

A construction platform comprising:

• a plurality of curved platforms and a plurality of columns, wherein the plurality of columns are configured to be distributed in a manner of surrounding a cylindrical building, the plurality of curved platforms are connected to and movable along the plurality of columns, the plurality of curved platforms are connected to one after the other to form a ring-shaped platform that surrounds the cylindrical building and is movable along lengths of the plurality of columns, each curved platform of the plurality of curved platforms is provided with one or more mounting brackets, and each mounting bracket of the one or more mounting brackets is provided with:
• one or more movable brackets, wherein each of the one or more movable brackets is provided with one or more drive wheels that are motor drivable;
• one or more pressing mechanisms that are electrically controllable, wherein the one or more pressing mechanisms correspond one-to-one to the one or more movable brackets, and each of the one or more pressing mechanisms is configured to drive a corresponding movable bracket of the one or more movable brackets to move towards the cylindrical building, such that the one or more drive wheels that are arranged on the corresponding movable bracket are pressed against a side wall of the cylindrical building;
• one or more locking mechanisms electrically controllable, wherein the one or more locking mechanisms are configured to lock the each mounting bracket to the cylindrical building;
• one or more movable rods, wherein each movable rod of the one or more movable rods is sleeved with a first spring, a first end of the each movable rod is provided with a suction cup, and the first spring is configured to press the suction cup to contact the side wall of the cylindrical building;
• a pumping mechanism in communication with the suction cup, wherein the pumping mechanism is configured to, when the suction cup contacts the side wall of the cylindrical building, pump air between the suction cup and the side wall of the cylindrical building, to form a vacuum cavity between the suction cup and the side wall of the cylindrical building such that the suction cup sucks and holds on the cylindrical building;
• and
• one or more emergency braking mechanisms, wherein the one or more emergency braking mechanisms correspond one-to-one to the one or more movable rods, and each of the one or more emergency braking mechanisms comprises:
• a sprocket arranged on the each mounting bracket;
• a chain that matches the sprocket, wherein a first end of the chain is connected to a second end of a corresponding movable rod of the one or more movable rods, a second end of the chain is connected to a counterweight, the counterweight is used in detecting whether the each curved platform is in a normal state or in an abnormal falling state, and wherein:
• when the each curved platform is in the normal state, the counterweight is configured to pull the chain to drive, by a gravity of the counterweight, the corresponding movable rod and the suction cup that is arranged on the corresponding movable rod to move away from the side wall of the cylindrical building;
• and
• when the each curved platform is in the abnormal falling state, under an action of inertia of the counterweight, the suction cup arranged on the corresponding movable rod is pressed by the first spring sleeved on the corresponding movable rod to contact the side wall of the cylindrical building to form the vacuum cavity between the suction cup arranged on the corresponding movable rod and the side wall of the cylindrical building;
• an angle sensor, wherein the angle sensor is connected to the sprocket and is configured to detect a rotating direction of the sprocket and a rotating angle of the sprocket;
• and
• a configuring assembly for configuring the rotating direction of the sprocket, comprising:
• a ring gear that is fixedly arranged on the sprocket and is coaxial with the sprocket;
• a mounting sleeve arranged on the each mounting bracket;
• a configuring rod that is movable, wherein the configuring rod is sleeved with a second spring, a first end of the configuring rod is provided with a plate pressable by the second spring, both the plate and the second spring are arranged in the mounting sleeve, the second spring is connected to the mounting sleeve, and a first end of the second spring is configured to contact and press the plate;
• a pawl arranged on a second end of the configuring rod, wherein the pawl is configured to unidirectionally swing;
• a torsion spring connected between the pawl and the second end of the configuring rod, wherein the torsion spring is configured to cause the pawl to reset to a position at which the pawl is insertable between two teeth of the ring gear;
• an electromagnet arranged on the mounting sleeve and electrically controllable;
• and
• a magnetic block arranged on the configuring rod and adjacent to the electromagnet;
• and wherein:
• when the each curved platform is in the normal state, the second spring is configured to press the plate arranged on the first end of the configuring rod to drive the configuring rod and the pawl arranged on the second end of the configuring rod to move away from the ring gear, such that the rotating direction of the sprocket is not limited;
• and
• when the each curved platform is in the abnormal falling state, the electromagnet is configured to be activated to repel the magnetic block, such that the configuring rod and the pawl arranged on the second end of the configuring rod are driven to move towards the ring gear, the pawl enters between two teeth of the ring gear, and the sprocket is prevented from rotating in a direction that leads the corresponding movable rod and the suction cup that is arranged on the corresponding movable rod to move away from the side wall of the cylindrical building.
