[0046] In this embodiment, the lifter 4 is a cuboid (shell 47) with a cavity, and two raised sliders 41 are provided on each side of the long direction of the cavity. In order to ensure that the use structure of the lifter is not affected and to reduce its own weight, the lifter itself is hollowed out, and the side is in the shape of an "I". There is a gear 42 in the middle of the short direction of the cavity, and the diameter of the gear 42 is exactly the distance between the two arms in the cavity. The gear is fixedly connected to a rod, and the rod runs through the lifter. The lifter has a certain wall thickness, and a hexagonal chuck is fixed on one side of the rod at a distance of one wall thickness from the gear, and there is a cavity of the same shape on the side close to the lifter. The thickness of the gear is the length of the cavity section minus a wall thickness, and there is a rocker at each end of the rod.

[0047] In this embodiment, the middle position of the short side direction of the cage 5 is fixedly connected to the lower end of the lower arm. The cage is welded with square steel keels.

[0049] Example 2

[0050] The operating platform for the construction of an inverted ceiling panel of the present embodiment comprises a hook, an upper arm, a lower arm, a lifter, a cage and a hanging plate as a whole.

[0051] The hook is made of square steel and is open as a whole. The lower swing of the hook is consistent with the vertical position and direction of the purlin. Two ball bearings are fixed on the upper crossbar to reduce resistance during the overall movement of the platform.

[0052] The cross section of the upper arm is rectangular and fixedly connected to the lower swing rod. One side of the upper arm is a gear track of a certain length, and two adjacent surfaces each have a groove slideway.

[0053] The cross section of the lower arm is rectangular and fixedly connected to the hanging basket. One side of the lower arm is a gear track of a certain length, and two adjacent surfaces each have a groove slideway.

[0054] The lifter is a rectangular cavity structure with a certain thickness and rigidity. When the structural use conditions are met, the middle part of the two sides of the front of the rectangular block is removed for easy maintenance, and the front is in the shape of an "I". There are two sliders on each long surface of the cavity, corresponding to the groove slideway on the support arm, and the distance between the slider and the short side of the cavity is consistent with the distance between the slideway and the back of the gear track, so as to ensure that the back of the gear track of the upper and lower arms is close to the inside of the short side of the cavity in the lifter. A gear is arranged in the lifter, and the diameter is consistent with the spacing of the gear tracks of the upper and lower arms. The thickness of the gear should be less than the length of the short direction in the cavity, leaving a length of the wall thickness of the lifter. The gear is fixedly connected to a rod, and the rod passes through both sides of the lifter. A hexagonal block is also fixed on the rod, located on one side of the lifter, and is separated from the gear by a lifter wall thickness. The rod passes through one side of the lifter and leaves a hexagonal hole of the same size as the hexagonal block. There is a round hole on the other side of the lifter, which is consistent with the diameter of the rod. After the rod passes through the round hole, it is guaranteed to have a length of at least one wall thickness. Two rockers are arranged at both ends of the rod. By rotating the rocker clockwise and counterclockwise, the upper arm and the lower arm can be moved relative to each other. When the appropriate position is reached, the hexagonal block on the outside of the lifter is inserted into the lifter to brake the gear. The end of the groove slide on the arm is a safety limit for downward movement.

[0055] The cage is made of square steel keels welded together in a rectangular shape. The lower arm is connected to the middle keel on the short side. The two keels at the bottom are arranged perpendicular to the short direction. A step plate with a rectangular hole is arranged on the top. The top one on the rectangular side is a movable keel, one end of which is hinged to the connected keel, and the other end is fixed with a pin to facilitate the operator to enter.

[0056] The hanging plate is composed of two lightweight and high-strength alloy profiles (straight profiles). There is a cross bar under the cage that is fixedly connected to the two profiles. A hanging rod is fixed in the middle of the cross bar. The other end of the hanging rod is fixed to a rigid plate. The plate is located above the cage step plate and its size is the same as the hole in the step plate.

[0057] like Figure 7 , 8 As shown, the specific implementation method of an operating platform for anti-ceiling board construction in this embodiment is as follows:

[0058] Step 1: Assemble the hook, upper arm, lower arm, lifter and hanging basket on the ground, check whether there is any open welding on each part of the operating platform, and after the inspection, use a car crane to lift the self-made platform to the roof purlin. The number of operating platforms can be arranged according to the number of purlins between columns. The direction and height of each operating platform are consistent, and the lifter is in the center of the gear track, and the hook end is in the opposite direction of construction.

[0059] Step 2: Use machinery to pull a safety rope under each purlin. The two ends of the safety rope are hung between two adjacent steel beams. The safety rope passes through the keel on the hanging basket. The safety rope has one function to ensure the safety of the cage and prevent it from falling. Another function is to serve as a traction rope for the construction of the hanging basket.

[0060] Step 3: Use a boom truck to transport the construction workers to the hanging basket. The construction workers' safety belts must be tied to the roof purlins. It is strictly forbidden to hang the safety belts on the hanging basket. The safety belts must be "five-point double-hook" safety belts and worn correctly. They must not be tied around the waist alone. Then put the plates on the hanging board and the fixed hanging rod in the hollow position in the middle of the stepping board in the hanging basket. When all the plates are laid, use the connection and unloading under the hanging basket to fix the long alloy profiles to the hanging rods in turn.

[0061] Step 4: After the workers in the cage are ready, the roof workers will fix two 1.5-ton pulleys with a spacing of 5m on the purlins. The roof panels are installed as a whole panel. The construction of one panel requires 6 or 7 construction workers in the operating platform to complete it. The ground workers use the pulley to manually put the panel on. The ground workers use the pulley to put the roof panel on the roof, and the workers in the cage install the roof panel together. After the roof panel is on the roof, the cage workers start to use electric drills to nail and fix it. After fixing, the cage safety rope is used as traction to move the cage to install the next anti-ceiling panel until the operating platform moves to the steel beam position.

[0062] Step 5. The state of the hanging board during construction is that it is always hung on the keel below the cage through the plate on the hanging board. When moving to the steel beam position, the operator of an operating platform first steps on the plate, and controls the lifter at the same time to move the rod horizontally to remove the hexagonal block (block) that fits on the lifter. At this time, the rocker can be controlled to rotate the gear to drop the cage on the hanging board. At this time, the operator stands on the plate on the hanging board and continues to control the rocker to move the hook upward to disengage from the purlin. Then stand on the plate to move the hook below the purlin, and then rotate the direction of the cage with the plate as the center, so that the hook crosses the steel beam. Then turn the rocker, lift the upper arm so that the opening of the hook is above the purlin, adjust the hook to enter the purlin, turn the rocker, lower the upper arm so that the hook falls on the purlin, and continue to turn the rocker to lift the lower arm to lift the cage that has fallen on the hanging board. When the bottom keel of the cage is lifted to the bottom of the plate, the rod can be moved horizontally to insert the hexagonal block (block) into the lifter, fixing the gear and the arm to stabilize. Repeat this operation for the other half of the cage to cross the steel beam as a whole.

[0063] Step 6: After the safety rope in the other span is passed through the cage and fixed, the safety rope in the completed span is taken out. Similarly, the personnel need to fasten the safety belt on the purlin on the first span before taking out the safety belt on the completed span. After the daily construction is completed, the workers and the operating platform are moved to the ground by machinery.
