The trailer further comprises a controller; a distance measuring sensor 17 for measuring the distance between the support block 18 and the rack 19 is arranged at the position, close to the gear 16, of the support block 18; the two distance measuring sensors 17 and the corresponding electromagnet blocks 22 are electrically connected with the controller; under the first state, electromagnet block 22 circular telegram has magnetism, and electromagnet block 22 is fixed with magnet block 12 looks attraction on corresponding guard plate mechanism 6 this moment, and when range sensor 17 monitoring self and rack 19 apart from reaching the threshold value (rack 19 is about to mesh mutually with gear 16), transmission signal to controller, controller control electromagnet block 22 circular telegram loses magnetism, loses the fixed action to corresponding magnet block 12, and gear 16 can drive whole piece 18 and rotate.
An angle sensor is arranged on the gear 16; the angle sensor and the corresponding electromagnet block 22 are electrically connected with the controller; when the gear 16 rotates and the angle sensor detects the rotation of 90 ° (mutual transition from the first state and the second state), the controller controls the electromagnet block 22 to be energized, restores the magnetism, and fixes the corresponding magnet block 12 again.
The motor 14 and the corresponding electromagnet blocks 22 are electrically connected with the controller, when the second state needs to be changed into the first state again, the motor 14 is controlled to rotate in the reverse direction, the controller controls the two electromagnet blocks 22 not to be electrified, magnetism is lost, and fixing effect on the corresponding magnet blocks 12 is lost.
As shown in fig. 1-5, the working principle and flow of the present invention are as follows:
in the first state, as shown in fig. 1, the two electromagnet blocks 22 are energized and have magnetism, at this time, the two electromagnet blocks 22 are attracted and fixed to the magnet block 12 on the corresponding protection plate mechanism 6, at this time, the two protection plate mechanisms 6 are fixed, the fixed plate 3, the moving plate 4 and the rack 19 of the protection plate mechanism 6 are vertically arranged, the rack 19 is not in contact with the gear 16, the motor 14 is started, the driving wheel 15 is driven by the motor 14 to rotate clockwise (as exemplified by the left protection plate mechanism 6 in fig. 1, the motor 14 of the right protection plate mechanism 6 is rotated reversely), the driven wheel 10 is driven to rotate by the driving belt 9, the part of the driving belt 9 fixedly connected with the sliding block 21 moves upwards, at the moment, the driving belt 9 drives the sliding block 21 to move upwards along the groove 1801 of the supporting block 18, the L-shaped connecting plate 20 moves upwards along with the sliding block 21, so that the moving plate 4 moves upwards, and the height of the protection plate 8 formed by the moving plate 4 and the fixed plate 3 is increased; in the same way, on the contrary, when the driving wheel 15 rotates counterclockwise under the driving of the motor 14, the driving wheel 10 is driven to rotate by the driving belt 9, the part of the driving belt 9 fixedly connected with the sliding block 21 moves downwards, at this time, the driving belt 9 drives the sliding block 21 to move downwards along the groove 1801 of the supporting block 18, and the L-shaped connecting plate 20 moves downwards along the sliding block 21, so that the moving plate 4 moves downwards, and further, the height of the protection plate 8 formed by the moving plate 4 and the fixing plate 3 is lowered. The height of the protective plate 8 is adjusted according to different heights of the goods, and the rack 19 is not contacted with the gear 16 all the time in the process of adjusting the height.
When the goods need to be unloaded, when the driving wheel 15 is driven by the motor 14 to rotate counterclockwise (or the left side protection plate mechanism 6 in fig. 1 exemplifies that the motor 14 of the right side protection plate mechanism 6 rotates reversely), the driving belt 9 drives the rack 19 to move downward through the sliding block 21 and the L-shaped connecting plate 20, when the distance measuring sensor 17 detects that the distance between the driving wheel and the rack 19 reaches a set threshold (namely, the distance is meshed with the gear 16), a signal is transmitted to the controller, the controller controls the two electromagnet blocks 22 to be not electrified and lose magnetism, and loses the fixing effect on the corresponding magnet block 12, when the rack 19 moves to be meshed with the gear 16, the gear 16 is driven to rotate counterclockwise or clockwise, the connecting shaft 23 drives the corresponding support block 18 to rotate counterclockwise (the left side protection plate mechanism 6) or clockwise (the right side protection plate mechanism 6) to rotate towards the outer side of the carriage bottom plate 1, and when the angle sensors on the two gears 16 detect that the rotation angle reaches 90 degrees, the controller controls the two electromagnet blocks 22 to be energized to restore the magnetic properties, and fixes the corresponding magnet block 12 again, and the second state is assumed as shown in fig. 4.
When the second state needs to be changed into the first state again, the motor 14 is controlled to rotate reversely, the controller controls the two electromagnet blocks 22 not to be electrified, the magnetism is lost, the fixing effect on the corresponding magnet block 12 is lost, the driving wheel 15 rotates clockwise under the driving of the motor 14 (or as an example of the left side protection plate mechanism 6 in the figure 1, the motor 14 rotates reversely by the right side protection plate mechanism 6), the driving belt 9 drives the rack 19 to move towards the direction close to the connecting frame I11 through the sliding block 21 and the L-shaped connecting plate 20, the rack 19 pushes the gear 16 to rotate clockwise (the left side protection plate mechanism 6) or anticlockwise, the corresponding support block 18 is driven to rotate clockwise (the left side protection plate mechanism 6) or anticlockwise (the right side protection plate mechanism 6) through the connecting shaft 23, when the angle sensors on the two gears 16 detect that the rotation angle reaches 90 degrees, the controller controls the two electromagnet blocks 22 to be electrified, the magnetism is restored and the corresponding magnet block 12 is fixed again, and at this time, as shown in fig. 1, the state is the first state.
