The four sides of the uppermost edge are designed into smooth water caltrops, and the periphery and the bottom of the inner side of the water caltrop are provided with cushions. The cushion pad may be made of rubber. The cushion pad can be thickened or reduced according to the weight of the conveyed articles, and is welded on the inner side of the carrying box 13 through an expansion bolt.
Compared with the traditional conveying belt, the conveying belt of the traditional conveying belt is separated to be manufactured into the T-shaped supports 2, and the articles to be conveyed are placed in the carrying boxes 13 on the T-shaped supports 2, so that the phenomenon that the conveying belt of the traditional conveying belt is not full is avoided, fixed-point conveying can be performed, conveying efficiency is improved, energy consumption consumed by the conveying belt can be reduced, and energy conservation and environmental protection are achieved. In addition, a plurality of T-shaped supports 2 can be placed on the U-shaped guide rail 1 for conveying, the movement of each T-shaped support 2 is controlled independently, fixed-point type conveying can be achieved, and conveying efficiency is further improved. In the same time, the energy consumption is reduced, thereby further reducing the energy consumption and realizing the permanent magnet transmission with low energy consumption.
Technical effects
The secondary coil winding 4 of the linear motor is made very long and is laid on the whole U-shaped guide rail 1, while the primary coil winding 5 of the linear motor is made very short and is only as short as the T-shaped support 2. When a current flows through the primary and secondary coil windings of the linear motor after the current is applied, an ampere force is generated. According to the left-hand rule, the coil can generate a force to the left or the right according to the difference of the current directions in the coil, and the force is the thrust for directly making the linear motor do linear motion. The phase sequence of the three-phase voltage is changed, the direction of a traveling wave magnetic field generated by electromagnetic induction is changed, the direction of the generated thrust is changed along with the change of the direction of the traveling wave magnetic field, and then the movement direction is changed, so that the reciprocating motion of the linear motor can be realized, and the T-shaped support 2 can also realize the reciprocating motion.
Permanent magnets are installed on the U-shaped guide rail 1 and the T-shaped support 2 and are kept at the same level, so that no matter the T-shaped support 2 is tilted to the side, due to the fact that the permanent magnets installed on the U-shaped guide rail 1 and the T-shaped support 2 keep the same polarity, mutual repulsive force exists, the tilted inclination is kept in a vertical state through the repulsive force, the tilting phenomenon caused by special conditions in the conveying process of the T-shaped support 2 is avoided, and the safety of the T-shaped support 2 in the conveying process is guaranteed.
The T-shaped support 2 is provided with a speed monitoring component 10 and a displacement monitoring component 11, when the T-shaped support 2 is to be conveyed to a turning position, the T-shaped support is conveyed to a designated position, the displacement monitoring component 11 on the T-shaped support 2 transmits the displacement of the T-shaped support 2 to a controller through communication transmission, the controller reduces the speed of the T-shaped support 2 through a series of operations such as control commands, the speed monitoring component 10 on the T-shaped support 2 monitors the speed of the T-shaped support 2 in real time so as to be adjusted in time, and therefore the T-shaped support 2 slowly passes through the turning position. When the T-shaped support 2 turns completely and enters the straight-line section conveying, namely the displacement monitoring part 11 conveys the displacement of the T-shaped support 2 to the controller, the controller increases the speed of the T-shaped support 2 again and continues to finish the conveying, so that the overturning is further prevented, and the safety of the conveying process is ensured.
After the power supply device supplies power, the polarity of a magnetic field generated by electromagnetic induction of a coil winding on the U-shaped guide rail 1 is always consistent with that of a permanent magnet installed on the T-shaped support 2, so that a repulsive force exists between the U-shaped guide rail 1 and the T-shaped support 2, the T-shaped support 2 is suspended, and a gap exists between the T-shaped support 2 and the U-shaped guide rail 1. The clearance between the T-shaped support 2 and the U-shaped guide rail 1 is monitored in real time through the clearance monitoring component 12 for feedback, so that the adjustment is carried out in real time, the clearance between the T-shaped support 2 and the U-shaped guide rail 1 is maintained at a certain value, the T-shaped support 2 is ensured not to be in contact with the U-shaped guide rail 1 all the time, and the energy consumption is further reduced.
The carrying box 13 on the T-shaped support 2 is used for placing the goods required to be conveyed, is structurally designed into a cuboid, removes the top edge, can carry out goods placing or taking out, and is provided with a cushion pad on the inner side. When the conveying goods, because of special circumstances such as outage, because weight and inertia of goods self, the goods can be to leaning forward crowded and carry thing case 13 and bump, the blotter just can cushion by article and carry the extrusion that forms in the twinkling of an eye between the thing case 13, reduces the extrusion degree to minimumly through the blotter, has guaranteed the quality of conveying goods.
