In other embodiments, the stable hoisting device for municipal building engineering further comprises a hoisting rail extending in the left-right direction, and the hoisting mechanism can slide along the extending direction of the hoisting rail.
In combination with the above embodiment, the use principle and working process of the embodiment of the present invention are as follows:
In the initial state, the front end and the rear end of the two wire ropes 211 are respectively lifted at both ends in the length direction of the cuboid weight, and the volumes of the cuboid weights before and after the winding drum are different. Then, the telescopic arm 101 of the crane 100 is controlled to hoist, so that the cuboid weight is hoisted. In the lifting process, if the wind along the axis direction (i.e. the left-right direction) of the winding drum is received, the cuboid heavy object is unbalanced in stress on the front side and the rear side of the axis of the winding drum, so that the cuboid heavy object is easy to rotate, the rotating plate 220 can be driven to rotate in the rotating process of the cuboid heavy object, the speed sensor on the universal wheel 221 detects the rotating speed of the rotating plate 220 when the rotating plate 220 rotates, and the rotating speed is transmitted to the controller through a signal, so that the controller controls the motor to drive the winding drum to rotate. As shown in fig. 4, the drum rotates clockwise to make the front end and the rear end of the two wire ropes 211 at the same horizontal plane, so that the forces of the cuboid weights on the front side and the rear side of the axis of the drum are balanced. At this time, the cuboid weight rotates to a position where the length direction of the cuboid weight is parallel to the direction of wind, namely, a downwind position, and then the cuboid weight automatically stops rotating. The greater the speed sensor detects the rotation speed of the rotating plate 220, the greater the rotation speed of the motor driving winding drum is by the controller, so that the cuboid weight is adjusted to be in a stress balance state as soon as possible. When the cuboid heavy object rotates to the downwind position, the winding drum also stops rotating due to the automatic stopping of the cuboid heavy object, and the windward area of the cuboid heavy object reaches the minimum at the moment, so that the shaking of the cuboid heavy object can be avoided, and the hoisting stability is improved.
According to the invention, the two ends of the two steel wire ropes 211 are connected with the cuboid weight, so that compared with the arrangement of four steel wire ropes 211, the number of the steel wire ropes 211 is reduced, the situation that the cuboid weight cannot be in a horizontal state due to different stretching coefficients of the steel wire ropes 211 is avoided, and stable hoisting is ensured.
The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.
The above examples merely represent a few embodiments of the present invention, which are described in more detail and are not to be construed as limiting the scope of the present invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of the invention should be assessed as that of the appended claims.
