Second embodiment:
based on the first embodiment, in the actual use process, because the four clump weights 5 are uniformly distributed at the four right-angle positions of the surface of the rotating seat 3 and cannot be adjusted in position, and the boiler is heavy, after the boiler is lifted, the boiler can be far away from the chassis 1, so that the stress of the lifting device is uneven, the stress of the rotating shaft 2 and the limiting inserted rod 11 is unbalanced, after the boiler is used for a long time, the rotating shaft 2 and the limiting inserted rod 11 are easily worn and deformed, so that the stability and the safety of the lifting device are affected, in addition, the farther the horizontal distance between the lifted boiler and the chassis 1 is, the unbalanced stress is larger, the rotating shaft 2 and the limiting inserted rod 11 are worn more seriously, in order to solve the problem, the two sides of the rotating seat 3 are respectively provided with the guide grooves 51 corresponding to the clump weights 5, and the guide grooves 51 are rotationally connected with the lead screws 52, the screw rod 52 is sleeved with a slide block 53 in sliding fit with the side surface of the guide groove 51 through threads, the side surface of the rotating seat 3 is provided with a motor 54, and an output shaft of the motor 54 is fixedly connected with the end part of the screw rod 52.
Before the hook 10 is not combined with the boiler, the gravity center of the whole device is positioned on the chassis 1, the balancing weights 5 are uniformly distributed on the rotating seat 3, the stress of the rotating shaft 2 and the limiting insertion rods 11 is uniform, in the process that the boiler is lifted and starts to move, in order to enable the boiler to reach the installation position, the position of the boiler needs to be adjusted by using a first angle adjusting mechanism and a second angle adjusting mechanism, when the first angle adjusting mechanism is used for driving the vertical oscillating rod 6 to swing towards one side close to the hook 10, the included angle between the vertical oscillating rod 6 and the rotating seat 3 is reduced, meanwhile, the boiler is far away from the chassis 1, when the second angle adjusting mechanism is used for driving the telescopic fixing pipe 8 to rotate and the telescopic fixing pipe 8 is gradually close to the horizontal state, at the moment, the horizontal distance from the boiler to the chassis 1 is further increased, in addition, when the external air pump is used for driving the telescopic shaft 22 to extend, the horizontal distance between the boiler and the chassis 1 is further increased, in the process, the gravity center of the hoisting device gradually moves forwards and is finally concentrated on the boiler, so that one side of the chassis 1 and the rotating seat 3, which is far away from the boiler, has a tendency of moving upwards, meanwhile, the rotating shaft 2 and the limiting insertion rod 11 can be greatly abraded and are easy to deform, at the moment, the two motors 54 close to one side of the hook 10 are started to drive the screw rod 52 at the side to rotate, so that the counterweight block 5 can be driven by the sliding block 53 to slide, the counterweight block 5 is far away from the hook 10, meanwhile, the two motors 54 far away from one side of the hook 10 are started, the counterweight block 5 at the side is driven by the screw rod 52 and the sliding block 53 to slide, the counterweight block 5 at the side is far away from the hook 10, the problem of unbalanced stress of the whole device can be effectively improved, the position of the gravity center can be adjusted, the gravity center is gradually close to the chassis 1, and the whole stability of the device can be improved, the problem of unbalanced stress of the rotating shaft 2 and the limiting inserted rod 11 is solved.
It is worth noting that, first cylinder 16 extends, and the distance between the boiler and the chassis 1 is reduced, and first cylinder 16 contracts, and the distance between the boiler and the chassis 1 increases, so when starting first cylinder 16 and shortening, can start motor 54 simultaneously, keep away from couple 10 through lead screw 52 and slider 53 drive balancing weight 5, can adjust the focus position, make this device whole more balanced stable.
Similarly, the extension of the second cylinder 19 will cause the boiler to be far away from the chassis 1, therefore, when the extension of the second cylinder 19 is started, the motor 54 can be started simultaneously, the counterweight 5 is driven by the screw rod 52 and the slide block 53 to be far away from the hook 10, and the gravity center position can be adjusted.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
