It is worth noting that, after whether the goods are in an eccentric state, the lifting machine 11 can lift the goods, the pressure detected by the pressure sensor and the pressure value of the pressure detection fixed disk 8 for the total weight of the goods are detected, the controller can calculate the weight of the goods according to the weight value detected on the pressure detection fixed disk 8, when the controller detects that the weight of the goods exceeds a threshold value, the first electric push rod 16 is controlled to extend outwards, the auxiliary clamping plate 15 can be driven to slide outwards along the main clamping plate 14, so that the main clamping plate 14 and the auxiliary clamping plate 15 can synchronously clamp the goods, the clamping moment arms on two sides of the goods are increased, the clamping lifting of the goods is stable and safe, and the extending amount of the first electric push rod 16 is increased along with the increase of the weight of the goods detected by the controller, so that the clamping moment arm of the auxiliary clamping plate 15 is adjusted according to the weight change of the goods, the greater the extending distance of the auxiliary clamping plate 15 is, the farther the clamping point of the goods is, the greater anti-tipping effect of the goods is, the greater the lifting effect is that the main clamping plate 14 and the lifting machine 11 can not swing in the lifting process when the lifting machine 6 is driven to greatly, and the lifting equipment can not swing.
It is worth noting that, when carrying out the goods clamp through main grip block 14 and getting, can bind the goods with the lifting rope, then carry out auxiliary fixation with lifting rope articulates on pressure display indication pole 9, improve the spacing fixed effect of goods, and when carrying out the goods through lifting machine 11 and lifting by crane, the pressure value that detects on the pressure detection fixed disk 8 can all carry out the show directly perceivedly through pressure display indication pole 9, when lifting by crane the during operation, the staff can directly perceivedly see the weight distribution condition when the goods lifts by crane like this, the convenience is in time got the position to the clamp of goods and is adjusted, the security of lifting by crane is improved.
It should be noted that, when the crane 11 is clamping the goods, when the pressure difference detected on the pressure detection fixed disk 8 is not less than the threshold value, the clamping position of the goods is readjusted at this time to ensure the clamping stability of the goods, when the pressure difference detected on the pressure detection fixed disk 8 is less than the threshold value, the clamping and lifting operation of the crane 11 on the goods is in the safety range, in the process of conveying the goods by the crane 11, when the pressure sensor on the pressure detection fixed disk 8 detects that the weight distribution of the goods is eccentric and is in the safety range, at this time, in order to maintain the balance of the clamping and lifting device 6, the offset of the sliding balancing weight 29 is regulated and controlled by the indication of the pressure display indication rod 9, so that the balance adjustment can still be performed on the device when the goods is eccentrically clamped, specifically:
when the center of gravity of the goods deviates within the safety range, the pressure on the fixed pull rod at the deviated side is larger, the pressure on the fixed pull rod at the opposite side is the smallest, at this time, the numerical values detected by the pressure sensors on the plurality of groups of fixed pull rods are transmitted to the controller, the balance adjusting body 4 is controlled according to the deviation condition of the center of gravity of the goods, namely, the balance adjusting body 4 at the side with larger pressure value drives the sliding balance weight 29 to move towards the side close to the crane 11, and the balance adjusting body 4 at the side with smaller pressure value drives the sliding balance weight 29 to move towards the side far away from the crane 11, so that the real-time counterweight operation can be carried out on the device when the overturning moment generated by the device due to the deviation of the goods occurs.
In the process of the movable transportation by lifting the lifting machine 11, namely, when the sliding moving clamping frame 7 slides along the inside of the sliding conveying clamping groove 24, along with the movement of the lifting machine 11, the tipping moment received on the lifting support main body 1 can be increased, as the weight of the lifting machine 11 can be fully applied to the pressure detection fixed disc 8 when the lifting machine lifts the goods, then the pressure detected by the pressure sensor is equal to the weight of the goods, when the lifting machine 11 lifts the goods, the controller can calculate the weight of the goods according to the weight value detected on the pressure detection fixed disc 8, so that a control reference basis can be provided for the moving stroke of the sliding balancing weight 29, and the method specifically comprises the following steps:
the infrared ranging sensors 2 symmetrically arranged at the upper parts of the two ends of the track limiting plate 20 can detect the moving positions of the ranging detection plates 12 on the track limiting plate 20 in real time, the specific positions of cargoes can be determined, at this time, the data detected by the infrared ranging sensors 2 are transmitted to the controller, and as the weight of the sliding balancing weights 29 is fixed, the controller can complete linkage control on the plurality of groups of third electric push rods 25 according to the weight of the cargoes and the weight of the sliding balancing weights 29, so that the third electric push rods 25 at different positions can synchronously and independently operate to control each sliding balancing weight 29 to slide along the balancing frame 28, so that the sliding balancing weights 29 symmetrically arranged at the two ends of the track limiting plate 20 slide along the designated distances on the balancing frame 28 respectively, and the effect of balancing adjustment is achieved, and the track limiting plate 20 can be stably and safely supported by the stable supporting legs 21 without tipping in the process of lifting and conveying.
It should be noted that, the adjustment of the controller to the third electric putter 25 is based on the lever principle, and the offset distance of the sliding balance weight 29 is adjusted based on the weight of the cargo itself and the weight of the sliding balance weight 29 plus the offset distance of the crane 11 detected by the infrared ranging sensor 2, when the weight of the single lifted cargo is large, and the offset distance of the crane 11 detected by the infrared ranging sensor 2 is unchanged, at this time, the controller needs to increase the offset distance of the sliding balance weight 29 to adapt to the cargo with large weight, otherwise.
In summary, the adjustment of the offset distance of the sliding balance weight 29 is based on the weight of the cargo itself and the offset distance of the crane 11 detected by the infrared ranging sensor 2 during lifting, and the adjustment of the offset distance of the sliding balance weight 29 is completed by the cooperation of the two, so that the blindness and inaccuracy of adjusting the offset distance of the sliding balance weight 29 by the offset distance of the crane 11 detected by the infrared ranging sensor 2 can be avoided, and the problem that the weight amount generated by the movement of the sliding balance weight 29 and the required actual weight amount deviate greatly can be solved, so that the real-time position adjustment of the sliding balance weight 29 can be performed according to the weight of the cargo itself.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
