As shown in fig. 2, the pre-balancing stand 3 includes a pre-balancing stand body 301, a protection rod 303 is disposed at the upper end of the pre-balancing stand body 301, fixed connection posts 302 are disposed at the left and right sides of the protection rod 303, two controllable cylinders 305 are disposed in the pre-balancing stand body 301, the lower ends of the controllable cylinders 305 are connected to a balancing pressure rod 306, and a horizontal fixing plate 307 is disposed on the balancing pressure rod 306.
The pre-balancing process of the pre-balancing stand 3 is that the self-adjusting balancing stand 4 is in a horizontal state on the triple-link belt 101 in an initial state, at this time, the controllable air cylinder 305 controls the balancing pressure rod 306 to press downwards, and the tail end of the balancing pressure rod 306 is contacted with the left side and the right side of the balancing suspension rod 403, so that the balancing suspension rod 403 is in a balanced state. At this time, materials to be suspended and transported need to be placed on the suspension hook rings 411 of the first suspension position 405, the second suspension position 406 and the third suspension position 407, the self-adjusting balance rack 4 is firstly subjected to self-adjusting leveling, then transportation is started, when the whole self-adjusting balance rack 4 is transported to a bending section, the balance of the self-adjusting balance rack 4 is broken due to up-and-down fluctuation, and at this time, the self-adjusting balance rack 4 needs to be subjected to secondary balance adjustment to ensure that the materials are in a balance state in real time.

The working principle of each component in the self-balancing process of the self-adjusting balancing stand 4 is that when the balance of the self-adjusting balancing stand 4 is broken, in this embodiment, if the whole balancing suspension rod 403 tilts to the right, the whole state is sensed by the first attitude sensor 412 and the second attitude sensor 413, and feedback is generated to act on the controllable stepping motor 408, the controllable stepping motor 408 further controls the steering of the screw rods 409 at the left and right ends, so that the moving weight 410 at the right moves to the left, and the moving weight 410 at the left moves to the right, so that the balancing suspension rod 403 is balanced again. The signal difference of the balanced sensor is almost zero, and if the feedback is almost zero, the movable weights 410 on the left side and the right side keep still to maintain a balanced state.
The first permanent magnet 308 is vertically disposed so that one pole of the magnet faces downward, which is to ensure that the magnetic fields generated by the first permanent magnet 308 to the first attitude sensor 412 and the second attitude sensor 413 are equal in magnitude and same in direction in the balanced state, and ensure that the signal difference output by the two sensors is zero, and only in the unbalanced state, the two sensors generate different signal differences to drive the controllable stepping motor 408 to turn.
As shown in fig. 4, the triple chain belt 101 includes a protection chain belt 1012, outer chain belts 1011 are disposed on left and right sides of the protection chain belt 1012, and a plurality of buckle pull rings 10121 are uniformly disposed on the protection chain belt 1012.
Compared with the traditional static transmission frame, the three-chain belt 101 structure utilizes the outer chain belt 1011 to move by itself, and drives the whole pre-balance frame 3 and the self-adjusting balance frame 4 to move in a buckling mode, so that the stability of the whole transmission process is ensured, and the problem that the whole transport line stops due to the damage of a single transport trolley is avoided.
Secondly, the design of the protective chain belt 1012 is matched with the auxiliary lock ring 103 to firmly lock the pre-balance frame 3 on the whole triple chain belt 101, so that the problem that the transportation piece of the whole equipment collapses to cause damage to property and personnel when the chain is suddenly broken is avoided.
As shown in fig. 5, the outer chain belt 1011 includes two outer chain pieces 10111, an inner chain piece 10113 is disposed between the two outer chain pieces 10111, a pin 10112 is connected between the outer chain piece 10111 and the inner chain piece 10113, a caulking groove 10117 is disposed at the center of each inner chain piece 10113, a pushing connecting piece 10114 is disposed between two adjacent caulking grooves 10117, and a chain hole locking rod 10115 connected to the locking buckle 102 is disposed in the caulking groove 10117.
The principle of outer chain belt 1011 lock joint is that two outer chain pieces 10111 firmly lock inner chain piece 10113, promote connection piece 10114 to improve the toughness of chain belt, and chain hole locking lever 10115 tightly inserts in the locking is detained 102, guarantees that chain hole locking lever 10115 can not drop when outer chain belt 1011 moves, and then realizes driven purpose.
As shown in fig. 6, the material balance device control system provided by the present invention includes voltage difference signals output by the first attitude sensor 412 and the second attitude sensor 413, the voltage difference signals are sent to the amplifying circuit, the output end of the amplifying circuit is connected to the current driving circuit, and the current signal output by the current driving circuit drives the controllable stepping motor 408, so as to indirectly realize the function of controlling and adjusting the balance of the balance suspension rod 403.
As shown in fig. 6, the controllable stepping motor 408 includes a coil 4086 connected to the current driving circuit, two pole control pieces 4081 are symmetrically disposed on the left and right sides of the coil 4086, fixed cylinders 4082 are disposed on the outer sides of the two pole control pieces 4081, a telescopic spring 4084 is disposed in the fixed cylinder 4082, a second permanent magnet 4083 is connected to one end of the telescopic spring 4084 close to the two pole control pieces 4081, and a metal connecting piece 4085 is disposed at one end of the second permanent magnet 4083 close to the two pole control pieces 4081.
The balance device control system is the core of the whole balance process, when the whole device is in an unbalanced state, the first attitude sensor 412 and the second attitude sensor 413 receive different magnetic field strengths generated by the first permanent magnet 308, the output signal difference of the first attitude sensor and the second attitude sensor is amplified in an amplifying circuit, the amplified signal is still difficult to drive the coil 4086, a current driving operation needs to be carried out at the moment, when a voltage signal is converted into a current signal, the power is increased at the moment and then the coil 4086 is driven, and therefore the left end and the right end of the coil 4086 generate magnetic fields in fixed directions.
After the magnetic field is generated at the two ends of the coil 4086, the second permanent magnet 4083 in the fixed cylinder 4082 is attracted, because the second permanent magnet 4083 on the opposite side is the same magnetic pole, the right side of the two ends of the coil 4086 attracts the second permanent magnet 4083, and the other side repels the second permanent magnet 4083, at this time, only one section of the second permanent magnet 4083 is attached to the bipolar control plate 4081 with the metal connecting plate 4085. The rotation directions of the two-pole control pieces 4081 on different sides, which are connected with the controllable stepping motor 408, are different, so that the positions of the weights 410 are moved on the left side and the right side, and the purpose of adjusting balance is achieved.
As shown in fig. 6, the polarities of the opposite surfaces of the second permanent magnets 4083 on the left and right sides are the same, and the metal connecting pieces 4085 are made of copper or silver.
The metal connecting piece 4085 is a low resistance and non-ferromagnetic material, because the ferromagnetic material will move under the influence of the magnetic field generated at the two ends of the coil 4086, and once the resistance is too high, the heat loss will be increased and the energy consumption will be wasted, which affects the working process.
As shown in fig. 7, a method for using a material balance device of an intelligent suspension conveying system is characterized by comprising the following steps:
step 100, setting a balance angle of a pre-balance frame according to the size of an inclination angle between the initial end of the three-chain belt and a horizontal plane, and ensuring that the self-adjusting balance frame after pre-balance is parallel to the initial end of the three-chain belt when the transportation starts;
200, setting a rotating speed parameter of the controllable stepping motor according to different lead screw lengths, and finishing the feedback leveling within 0.5-1.5 seconds;
step 300, after initial parameters are set, switching on a power supply to perform a periodic test, and recording a periodic running condition of goods;
and step 400, after the setting is qualified, switching on the power supply to start working.
The specific process of adjustment in step 100 is to adjust the cylinder to control the inclination angle of the balance pressing rod according to the initial state of the pre-balance frame, so as to ensure that the pre-balance frame and the three chain belts are parallel to each other at this moment.
In step 300, the entries include the period of cargo transportation, the time for auto-leveling and the percentage of the total period of the balancing time for the entire process to determine the efficiency of balancing
The invention has the advantages that the self-adjusting balancing stand is matched with the material balancing device control system to realize self-correction of the self-adjusting balancing stand when the balance is broken, the time for preliminary balance is greatly reduced by the pre-balancing stand, the three-chain belt buckling mode transmission is used for replacing the traditional hanging trolley to automatically move, the stability of the whole transmission process is ensured, and the problem that the whole transport line stops due to the damage of a single transport trolley is avoided.
