[0017] like Figure 1 As shown, the utility model provides a building safety construction platform, including a base 1, four columns 2 are connected to the base 1, a workbench 3 is slidably connected between the four columns 2, and a driving device 4 is connected to the base 1, and the driving device 4 is used to drive the workbench 3 to move up and down.

[0018] like Figure 3 As shown, the driving device 4 includes a motor, which is connected to the base 1. The motor drives the rotating shaft 4.1 through a transmission mechanism. The rotating shaft 4.1 is connected to the base 1 through a bearing seat. The transmission mechanism is an existing belt and pulley mechanism, including a driving wheel 4.4. The driving wheel 4.4 is connected to the output shaft of the motor. The driving wheel 4.4 drives the driven wheel 4.6 through a transmission belt 4.5. The driven wheel 4.6 is sleeved and fixed on the rotating shaft 4.1. The motor can drive the rotating shaft 4.1 to rotate. Winding drums 4.2 are connected at both ends of the rotating shaft 4.1. A rope 4.3 is wound around the winding drum 4.2. The free end of the rope 4.3 is connected to the workbench 1. When the motor drives the winding drum 4.2 to rotate, the winding drum 4.2 will be wound around the rope 4.3, driving the workbench 3 to move upward.

[0019] A support plate 2.1 is connected between every two corresponding columns 2, and a guide wheel 2.2 is connected to each support plate 2.1. The guide wheel 2.2 guides the rope 4.3, that is, the free end of the rope 4.3 passes through the guide wheel 2.2 and is then connected to the workbench 1. When the winding drum 4.2 winds the rope 4.3, the workbench 1 moves upward. When the winding drum 4.2 releases the rope 4.3, the workbench 1 moves downward under the action of gravity.

[0020] like Figure 2As shown, a cavity 5 is provided in each column 2, and a sliding groove 6 is provided on one side of the cavity 5. The bottom of each cavity 5 is connected to a first oil tank 7, and a first piston 8 is slidably connected in the first oil tank 7. A piston telescopic rod 9 is connected to the first piston 8. The piston telescopic rod 9 includes a vertical tube, one end of the vertical tube is connected to the first piston 8, and a through hole 8.1 is provided on the first piston 8. The through hole 8.1 is connected to the vertical tube, so that the hydraulic oil in the first oil tank 7 enters the vertical tube through the through hole, and the second piston 9.1 is slidably connected in the vertical tube. When the second piston 9.1 moves upward, the hydraulic oil is extracted into the vertical tube, and when the second piston 9.1 moves downward, the hydraulic oil is discharged from the vertical tube. A piston rod 9.2 is connected to the upper side of the second piston 9.1, and the piston rod 9.2 is connected to a sliding plate 10. The sliding plate 10 drives the piston rod 9.2 to move. When the second piston 9.1 moves to the top of the vertical tube, the second piston 9.1 drives the vertical tube to move upward, and the vertical tube drives the first piston 8 to move upward.

[0021] A through hole is provided at the top of the first oil tank 7, and a vertical pipe is inserted into the through hole. The piston rod 9.2 is connected to the lower side of the sliding plate 10, and the sliding plate 10 passes through the sliding groove 6. The four sliding plates 10 are all connected to the workbench 3. The movement of the workbench 3 drives the movement of the sliding plate 10, and the sliding plate 10 drives the piston rod 9.2 to move.

[0022] A second oil tank 11 is connected to one side of each column 2, and the second oil tank 11 is connected to the corresponding first oil tank 7 through an oil pipe 12. A speed limiting valve 13 is connected to each oil pipe 12. The speed limiting valve 13 is an existing one-way speed limiting valve, which can control the flow rate of the hydraulic oil in the oil pipe 12 to the second oil tank 11, control the downward movement speed of the first piston 8 and the second piston 9.1, and then control the descending speed of the workbench 3 to prevent the workbench 3 from rapidly descending in the event of an accident.

[0023] When the workbench 3 moves upward, the sliding plate 10 will be driven upward by the sliding plate 10, and the sliding plate 10 will drive the piston rod 9.2 to move upward, and the piston rod 9.2 will drive the second piston 9.1 to move upward. The upward movement of the second piston 9.1 will draw the hydraulic oil in the first oil tank 7 into the vertical pipe. When the second piston 9.1 moves to the top of the vertical pipe, the second piston 9.1 will drive the vertical pipe to move upward, and the vertical pipe will drive the first piston 8 to move upward. The upward movement of the first piston 8 will draw the hydraulic oil in the second oil tank 11 into the first oil tank 7. In the event of an accident, the workbench 3 will move downward, and the piston rod 9.2 will drive the second piston 9.1 to move upward. The second piston 9.1 moves downward, causing the second piston 9.1 to squeeze the hydraulic oil in the vertical pipe downward. When the piston rod 9.2 completely enters the vertical pipe, it drives the first piston 8 to move downward, causing the first piston 8 to squeeze the hydraulic oil in the first oil tank 7 downward, causing the hydraulic oil to enter the second oil tank 11 through the oil pipe 12. A speed limiting valve 13 is connected to the oil pipe 12 to control the flow rate of the hydraulic oil in the oil pipe 12. The speed limiting valve 13 controls the descending speed of the first piston 8 and the second piston 9.1, thereby controlling the workbench 3 to descend slowly, preventing the workbench from rapidly descending due to an accident, causing panic and discomfort to employees.
