Specifically, in order to solve the technical problems that the existing rolling gate cannot be suddenly stopped and the mechanical structure is tired and damaged due to the sudden stop, the rolling gate drives the driving rod 13 to rotate through the lifting driving mechanism 15 in the normal working process, the driving rod 13 drives the curtain sheet 2 to lift through the belt of the driving component, the curtain sheet 2 enters the winding rail 12 along the linear rail 11 to finish the winding process, the tension spring 3 pulls the rope belt 4 through the connecting plate 31 in the process of closing the rolling gate, the rope belt 4 wound on the driving rod 13 starts to unwind, the driving rod 13 also rotates simultaneously, the driving rod 13 reversely drives the curtain sheet 2 to descend through the belt wheel component 14, in the process of descending the curtain sheet 2, the infrared sensor and the microwave sensor arranged on the bottom beam 21 are used for detecting the lower part of the curtain sheet 2 and the two sides of the curtain sheet 2 in real time, when the microwave sensor is used for monitoring moving targets on the two sides of the curtain sheet 2 in real time, in the process that the moving targets are gradually close to the curtain sheet 2, the microwave sensor sends a signal to the controller, the controller controls the flow rate through the speed regulating valve 64, as the curtain sheet 2 is also descended by the pulling of the tension spring 3 in the descending process, the connecting plate 31 descends to drive the piston head in the piston cylinder 62 to descend, the gas in the piston cylinder 62 is discharged through the gas outlet hole, since the controller reduces the speed-regulating flow, the air in the piston cylinder 62 is discharged slowly, so that the descending speed of the connecting plate 31 pulled by the tension spring 3 is delayed, the descending speed of the curtain sheet 2 is slowed down, the curtain sheet 2 can be stopped quickly at any time, when a moving object moves to the bottom of the curtain sheet 2, the infrared sensor on the bottom beam 21 immediately detects the shielding object, the infrared sensor sends a signal to the controller, the controller opens the locking mechanism 5, the locking driving assembly 53 fixes the fastening wheel 52, and since the fastening wheel 52 and the guiding wheel set 51 are meshed mutually and need to pass through the notch 41 on the rope belt 4, the guiding wheel set 51 stops rotating simultaneously when the fastening wheel 52 stops rotating, so that the movement of the string 4 is stopped, since the stopping of the string 4 is performed by the control of the notch 41, the string 4 is completely stopped when the control of the notch 41 is achieved, and the accurate control of the string 4 is lifted by controlling the arrangement density of the notch 41, so that the rapid and accurate stopping of the curtain sheet 2 is achieved, when the approach of the moving object is not monitored by the microwave sensor during the descent of the curtain sheet 2, but the descent of the curtain sheet 2 is required to be rapidly stopped when the shielding object is detected by the infrared sensor, the buffer mechanism 6 cannot be directly interposed, since the descent of the curtain sheet 2 is performed without the buffer mechanism 6, the locking mechanism 5 suddenly stops the movement of the string 4 if, the curtain sheet 2 will be caused to transmit the reaction force to itself and a series of connection structures such as the belt wheel assembly 14 and the like under the action of inertia, so that a plurality of mechanisms are greatly damaged by fatigue, in order to avoid the situation, the controller simultaneously opens the locking mechanism 5 and the anti-falling control mechanism 7, the air outlet path of the piston cylinder 62 is adjusted through the electromagnetic reversing valve 65, the compressed and discharged air in the piston cylinder 62 is directly injected into the airtight space in the guide wheel 71 of the anti-falling control mechanism 7, in particular, the air flow is injected into the air bag 73, the air bag 73 begins to expand and pushes the plurality of expansion plates 72 to radially extend from the inside of the guide wheel 71 to the outside thereof, the extending expansion plate 72 is clamped between tooth grooves of the straight rail 11 to finish the movement stop of the bottom beam 21 of the curtain sheet 2, and the locking mechanism 5 stops the continuous movement of the rope belt 4 to finish the rapid emergency stop operation of the curtain sheet 2 under double control, and the bottom beam 21 of the curtain sheet 2 is independently controlled to move in the emergency stop process, and the impact force is directly transferred to the straight rail 11 of the frame body 1, so that the transmission mechanism with poor impact resistance is prevented from suffering from excessive impact force.

The shaft fixing component 535 comprises a guide cover 5351, the guide cover 5351 is fixedly arranged in the frame body 1, a limiting cylinder 5352 is arranged in the guide cover 5351, a sliding piece 5353 is slidably arranged in the limiting cylinder 5352, one end of a movable rod 532 is movably connected with the guide sleeve 533, the other end of the movable rod 532 is rotatably connected with the sliding piece 5353, the sliding piece 5353 is elastically connected with the guide cover 5351 through a first spring 5354, clamping rods 5355 are symmetrically arranged on the sliding piece 5353 and are slidably connected with the sliding frame, two ends of the clamping rods 5355 are respectively an output end and a stress end, the output end of the clamping rods 5355 faces the movable rod 532, a second spring 5356 is sleeved at the stress end of the clamping rods 5355, the output end of the second spring 5356 abuts against the sliding piece 5353, a rolling body 5357 is arranged at the stress end of the clamping rods 5355, the inner wall of the guide cover 5351 is in a conical slope, and the rolling body 5357 is contacted with the slope; and

Specifically, in order to solve the technical problem that the stopping mode of directly clamping the side wall of the fastening wheel 52 is easy to slip in the conventional manner, the controller starts the linear driver 534, the linear driver 534 pushes the movable rod 532 to move, one end of the movable rod 532 pushes the sliding part 5353, the sliding part 5353 gradually approaches the bottom end of the guide cover 5351 against the action of the pretightening force of the first spring 5354, the sliding part 5353 drives the two clamping rods 5355 to move along with the sliding part 5355 in the moving process, the stressed ends of the two clamping rods 5355 are continuously close to each other against the pretightening force of the second spring 5356 under the guidance of the slope of the inner wall of the guide cover 5351, finally the output ends of the two clamping rods 5355 simultaneously clamp the movable rod 532, the gear 531 cannot rotate after the movable rod 532 is fixed, the fastening wheel 52 cannot rotate after the gear 531 is fixed, and the fastening wheel 52 cannot pass through the notch 41 on the rope belt 4 due to the mutual engagement of the fastening wheel 52 and the guide wheel set 51, and the rope belt 4 stops moving when the fastening wheel 52 stops rotating.
As shown in fig. 11 to 12, the following preferred technical solutions are provided:
The buffer mechanism 6 comprises a connecting rod 61, the connecting rod 61 is fixedly arranged at the bottom of the connecting plate 31, a piston cylinder 62 is arranged at the bottom of the frame body 1, the connecting rod 61 is in sliding connection with the piston cylinder 62, a piston head is arranged at the end part of the connecting rod 61, and a small hole is formed in the piston cylinder 62.
Specifically, in order to solve the technical problem of how to delay the descending speed of the curtain sheet 2, since the curtain sheet 2 is also lowered by the pulling of the tension spring 3 in the descending process, the connecting plate 31 descends to drive the piston head in the piston cylinder 62 to descend, the gas in the piston cylinder 62 is discharged through the small holes, and the gas in the piston cylinder 62 is discharged slowly due to the limited gas inlet and outlet amount of the small holes, so that the descending speed of the curtain sheet 2 pulled by the tension spring 3 is delayed, and the descending speed of the curtain sheet 2 is slowed down, so that the excessively high descending speed of the curtain sheet 2 is avoided, and the small-caliber flow of the small holes is not influenced when the piston cylinder 62 is in gas inlet due to the relatively slow ascending process of the curtain sheet 2.
As shown in fig. 11 to 12, the following preferred technical solutions are provided:
the buffer mechanism 6 comprises a connecting rod 61, the connecting rod 61 is fixedly arranged at the bottom of the connecting plate 31, a piston cylinder 62 is arranged at the bottom of the frame body 1, the connecting rod 61 is in sliding connection with the piston cylinder 62, a piston head is arranged at the end part of the connecting rod 61, an air inlet hole and an air outlet hole are formed in the piston cylinder 62, a one-way valve 63 is arranged at the air inlet hole, and a speed regulating valve 64 is arranged at the air outlet hole.
Specifically, in order to solve the technical problem of how to delay the falling speed of the curtain sheet 2, since the curtain sheet 2 is also pulled by the tension spring 3 to fall in the falling process, the connecting plate 31 falls to drive the piston head in the piston cylinder 62 to fall, the gas in the piston cylinder 62 is discharged through the gas outlet hole, and due to the difference in elasticity between different tension springs 3, the falling speeds of the curtain sheets 2 of different rolling gates are finally inconsistent, and the gas outflow speed in the piston cylinder 62 can be limited to be changed without being influenced by the load by arranging the speed regulating valve 64 in the gas outlet hole, so that the slow outflow of the gas in the piston cylinder 62 at a consistent speed is controlled.
The foregoing has shown and described the basic principles, principal features and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made therein without departing from the spirit and scope of the invention, which is defined by the appended claims.
