Use the detection mechanism to test the adjustment capability of the leveling mechanism.

[0027] The beneficial effects of this invention are as follows:

[0028] (1) In this invention, when the operating platform reaches the second-to-top floor, the horizontal plate can be pushed by the hydraulic cylinder, and the first support rod can be pushed by the horizontal plate. The roller can be moved towards the outer side of the building by the hinge of the rotating shaft, so that the scissor brace formed by the first support rod and the second support rod can lift the top seat upward, so that the position height of the operating platform reaches the top floor height, and the top floor can be directly reached. Compared with the prior art, this invention can avoid building a suspension on the top floor platform and solve the problem that the top floor construction cannot be directly reached in the prior art.

[0029] (2) In this invention, when there is a large difference in the load pressure detected by the pressure sensors at the bottom corners of both ends of the operating platform, it can be fed back to the PLC system, thereby controlling the motor and reducer to work. The motor and reducer drive the lead screw to rotate. Through the threaded engagement between the lead screw and the threaded sleeve, and the sliding limit between the frame and the support, the frame can move horizontally. Then, through the engagement between the pressure rail and the guide wheel on the frame, the posture of the operating platform can be adjusted.

[0030] (3) the operating platform in the present application is in a horizontal state, the guide wheels on the bottom surface of the operating platform are on the first rail surface of the two side pressure rails, when the moving frame moves from left to right, the second rail surface on the right side pressure rail extrudes the right side guide wheel downward, so that the right end of the operating platform has a tendency to move upward, while the left side guide wheel can move downward along the third rail surface on the left side pressure rail, thereby supporting the left end of the operating platform to gradually sink, and by analogy, when the moving frame moves from right to left, the second rail surface on the left side pressure rail extrudes the left side guide wheel downward, so that the left end of the operating platform has a tendency to move upward, while the right side guide wheel can move downward along the third rail surface on the right side pressure rail, thereby supporting the right end of the operating platform to gradually sink, so as to realize stable adjustment of the height difference between the two ends of the operating platform;

[0031] (4) in the present application, the load on the operating platform acts on the spring damper, which buffers the impact pressure of the top seat caused by the deflection of the operating platform due to the load difference, and also assists the leveling mechanism to adjust the posture of the operating platform according to the load difference detected by the two end detection mechanisms, so that the operating platform tends to be stable, and the pressure sensor can detect the load pressure of the spring damper, when the load pressure detected by the pressure sensors at the bottom corners of the two ends of the operating platform has a large difference, it can be fed back to the leveling mechanism, thereby adjusting the posture of the operating platform, so as to realize the balance of the pressure on the operating platform on the two ends of the jacking mechanism.

[0047] Please refer to Figure 4 With Figure 5 The jacking mechanism 51 is installed in the lift car 2, and the jacking mechanism 51 comprises a base 511 fixed to the inner side of the bottom of the lift car 2, a top base 512 horizontally arranged above the base 511, and a scissor strut 513 hingedly connected between the base 511 and the top base 512. The scissor strut 513 comprises a first strut 5131 and a second strut 5132, the middle portions of the first strut 5131 and the second strut 5132 are hingedly connected through a rotating shaft 5133, the two ends of the first strut 5131 are respectively hingedly connected with the base 511 and the top base 512, one end of the second strut 5132 is hingedly connected with the top base 512, and the other end of the second strut 5132 is rotatably connected with a roller 5134 rolling in the base 511. The base 511 is provided with a hydraulic cylinder 514 for adjusting the position and height of the top base 512, the bottom end of the hydraulic cylinder 514 is hingedly connected with the second strut 5132, and the output end of the hydraulic cylinder 514 is hingedly connected with a horizontal plate 5135 fixedly connected with the first strut 5131. It should be noted that the hydraulic cylinder 514 is arranged on the side away from the outer side of the building, and when the hydraulic cylinder 514 works, the horizontal plate 5135 can be pushed to move the first strut 5131, and the roller 5134 can be moved towards the outer side of the building through the rotating shaft 5133, so that the first strut 5131 and the second strut 5132 form a scissor strut 513 to lift the top base 512 upwards. Similarly, when the hydraulic cylinder 514 retracts, the first strut 5131 and the second strut 5132 form a scissor strut 513 to lower the top base 512 downwards.

[0048] Please refer to Figure 4 With Figure 6 The operating platform 52 is hingedly connected to the top of the jacking mechanism 51 and can be lifted to the top layer height position by the jacking mechanism 51 when the operating platform 52 reaches the next top layer. The middle portions of the operating platform 52 are fixedly connected with upper hinges 521, and the middle portions of the top base 512 are fixedly connected with lower hinges 515 hingedly connected with the upper hinges 521. The operating platform 52 can swing left and right with the upper hinges 521 and the lower hinges 515 as fulcrums according to the size of the load carried.

[0049] Please refer to Figure 4 With Figure 9The detection mechanism 53 is distributed on the bottom of the operation platform 52, and is used for detecting the load borne by the two ends of the operation platform 52. The detection mechanism 53 comprises four pressure sensors 531. Each pressure sensor 531 is fixed to the top surface of the top base 512 and is distributed in a rectangular shape. A spring damper 532 is arranged on the pressure sensor 531. The top part of the spring damper 532 is provided with a pressure cover 533 which is pressed on the bottom surface of the operation platform 52. The load borne on the operation platform 52 acts on the spring damper 532. The spring damper 532 buffers the impact pressure of the top base 512 caused by the deflection of the two ends of the operation platform 52 due to the load difference. At the same time, the spring damper 532 can assist the leveling mechanism 57 to adjust the posture of the operation platform 52 according to the load difference detected by the two detection mechanisms 53, so that the operation platform 52 tends to be stable. At the same time, the pressure sensor 531 can detect the pressure borne by the spring damper 532. When there is a large difference in the load pressure detected by the pressure sensors 531 at the bottom corners of the two ends of the operation platform 52, the pressure sensor 531 can feed back to the leveling mechanism 57, so as to adjust the posture of the operation platform 52, so that the pressure borne by the two ends of the jacking mechanism 51 on the operation platform 52 tends to be balanced.

[0050] In another embodiment, the detection mechanism 53 comprises a tension sensor. The operation platform 52 and the top base 512 are both fixed with a hanging rod at the two ends. The two ends of the tension sensor are fixed with hooks which are hooked on the hanging rods. The two tension sensors interact with each other to detect the load pressure borne by the two ends of the operation platform 52, and adjust the posture of the operation platform 52 according to the deviation of the pressure at the two ends, so that the operation platform 52 tends to be flat, and the pressure borne by the two ends of the jacking mechanism 51 on the operation platform 52 tends to be balanced. Compared with the previous embodiment, the detection method of the tension sensor is adopted in this embodiment, which has simple layout, reduces the detection cost, and is convenient for installation and replacement. However, the detection sensitivity is weaker than that of the pressure sensor 531.

The wheel set 54 comprises a wheel base 541 which is fixed to the bottom surface of the operation platform 52. The bottom part of the wheel base 541 is rotatably connected with a guide wheel 542.

The top surface of the pressing rail 552 is provided with a first rail surface 5521 and second and third rail surfaces 5522 and 5523 which are distributed at both ends of the first rail surface 5521. The first rail surface 5521 is horizontally arranged, and the second and third rail surfaces 5522 and 5523 are arranged in an inclined manner. The angles between the second and third rail surfaces 5522 and 5523 and the horizontal plane are consistent. The both ends of the pressing rail 552 are provided with stop portions 5524 which block the guide wheels 542. The support 56 is in rectangular distribution on both sides of the moving frame 55 for sliding limiting of the moving frame 55, so that the moving frame 55 can only move horizontally, as shown in Figure 4 the initial state, the guide wheels 542 on the bottom surface of the operation platform 52 are on the first rail surfaces 5521 of the pressing rails 552 on both sides. When the moving frame 55 moves from left to right, the second rail surface 5522 on the right pressing rail 552 extrudes the right guide wheel 542, so that the right end of the operation platform 52 has a tendency to move upward, while the left guide wheel 542 can move downward along the third rail surface 5523 on the left pressing rail 552, thereby gradually sinking the left end of the operation platform 52. Similarly, when the moving frame 55 moves from right to left, the second rail surface 5522 on the left pressing rail 552 extrudes the left guide wheel 542, so that the left end of the operation platform 52 has a tendency to move upward, while the right guide wheel 542 can move downward along the third rail surface 5523 on the right pressing rail 552, thereby gradually sinking the right end of the operation platform 52, so as to realize stable adjustment of the height difference between both ends of the operation platform 52.

[0053] Please refer to Figure 4 and Figure 7The leveling mechanism 57 drives the moving frame 55 to move horizontally according to the load difference detected by the two-end detection mechanism 53, and the moving frame 55 adjusts the posture of the operation platform 52 by acting on the wheel set 54, so that the jacking mechanism 51 bears the same load at both ends, the leveling mechanism 57 comprises a motor and a speed reducer set 571 and a fixed plate 572, both of which are fixed on the top base 512, the output end of the motor and the speed reducer set 571 is fixed with a lead screw 573, the end of the lead screw 573 away from the motor and the speed reducer set 571 is rotatably connected with the fixed plate 572 through a bearing, the lead screw 573 is externally threaded with a threaded sleeve 553, the threaded sleeve 553 is fixedly embedded in the frame body 551, the motor and the speed reducer set 571 are controlled by PLC, when there is a large difference in the load pressure detected by the pressure sensors 531 at the bottom corners of both ends of the operation platform 52, the difference can be fed back to the PLC system, and then the motor and the speed reducer set 571 are controlled to work, the lead screw 573 is driven to rotate by the motor and the speed reducer set 571, and the frame body 551 moves horizontally through the threaded cooperation of the lead screw 573 and the threaded sleeve 553, and the sliding and limiting of the support 56, and then the posture of the operation platform 52 is adjusted through the cooperation of the pressing rail 552 on the frame body 551 and the guide wheel 542.
