Second embodiment:
based on a hoisting device for boiler installation that first embodiment provided, in actual use, because four balancing weights 5 are in four right angle departments evenly distributed on the surface of rotating seat 3 and can not carry out position control, and the boiler is heavier, after the boiler hoists, the boiler can keep away from chassis 1, thereby lead to this hoisting device's atress uneven, and then can lead to the unbalanced stress of pivot 2 and spacing inserted bar 11, after long-time the use, lead to the wearing and tearing and the deformation of pivot 2 and spacing inserted bar 11 easily, thereby influence this hoisting device's stability and security, and, the boiler that lifts by crane is farther away from the horizontal distance of chassis 1, the unbalanced stress is more, pivot 2 and spacing inserted bar 11 wear more seriously, in order to solve this problem, rotating seat 3's both sides have seted up the guide slot 51 that corresponds with balancing weights 5 respectively, the internal rotation is connected with lead screw 52, screw thread cover has and has the slider 53 with guide slot 51 side sliding fit on the lead screw 52, rotating seat 3's side is equipped with motor 54, the output shaft of motor 54 is connected with the tip fixed connection of lead screw 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 inserted rod 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, the horizontal distance from the boiler to the chassis 1 is further increased, in addition, when an 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, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some technical features, and any modifications, equivalents, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
