[0024] In order to better implement this utility model, refer to Figure 3In one embodiment, the hanging assembly 8 includes a second screw rod 801, the upper end of which is mounted on the bottom of the mounting plate 4, and the second screw rod 801 is sequentially sleeved with a collar 802, a sleeve 803 and a spring 805 from top to bottom, the collar 802 is provided with an internal thread that matches the external thread of the second screw rod 801, and the lower end of the second screw rod 801 is provided with a fixing block 807, and the upper and lower ends of the spring 805 are respectively connected to the sleeve 803 and the fixing block 807, the two sides of the sleeve 803 are respectively hinged to one end of a first connecting rod 804, the other end of the first connecting rod 804 is provided with a hook 808, the two sides of the fixing block 807 are respectively hinged to one end of a second connecting rod 806, and the other end of the second connecting rod 806 is hinged to the middle part of the first connecting rod 804. Before lifting, it is necessary to adjust the distance between the two hooks 808 on a hanging assembly 8 to meet the distance between the lifting rings on the boiler. First, rotate the ring 802 to adjust the distance between the sleeve 803 and the fixed block 807, thereby adjusting the angle between the two first connecting rods 804. When it is adjusted to an appropriate size so that the boiler can be hung on the two hooks 808, hang the boiler. At this time, the weight of the boiler may drive the first connecting rod 804 to continue to pull the sleeve 803 downward, thereby further compressing the spring 805.

[0027] First, extend the second rod 702 and the third rod 703 from the first rod 701 and the second rod 702 respectively, adjust them to a position that matches the length of the boiler, and insert the pin 705 into the pin hole 704 where the first rod 701 and the second rod 702, and the second rod 702 and the third rod 703 are aligned. The two motors 304 simultaneously drive the connected first screw 301 to rotate, thereby driving the pulley 302 on the first screw 301 to rotate. The pulley 302 drives another pulley 302 to rotate through the belt 303, thereby driving the first screw 301 where the pulley 302 is installed to rotate, thereby realizing the downward movement of the movable ring 5 on the first screw 301, that is, the downward movement of the mounting plate 4. After the mounting plate 4 drives the hanging assembly 8 to move downward, the worker can then rotate the ring 802 to adjust the height of the sleeve 803, thereby adjusting the angle between the two first connecting rods 804, so that the distance between the two hooks 808 on the hanging assembly 8 meets the distance of the hanging ring on the boiler, and then connect the hanging ring to the hook 808, and the other hanging assembly 8 will also be adjusted. The motor 304 drives the connected first screw 301 to rotate in the opposite direction, so that the moving ring 5 can move upward. At this time, the mounting plate 4 will gradually drive the hanging assembly 8 to move upward, thereby driving the boiler to move upward. When the boiler has not yet left the ground, the weight of the boiler will pull the first connecting rod 808 to move upward. Rod 804, thereby pulling the sleeve 803 to move downward. To ensure that the boiler does not shake during the lifting process, the ring 802 continues to be rotated downward to make it close to the sleeve 803. At this time, the boiler can continue to be lifted. After the boiler is lifted to a certain height, the motor 304 is turned off, and the support column 1 is pushed, so that the universal wheel 6 at the bottom of the mounting base 2 drives the entire lifting device to move to the boiler installation position. The motor 304 is turned on and the first screw 301 is continued to be driven to rotate, so that the moving ring 5 thereon moves downward, driving the mounting plate 4, the hanging assembly 8 and the boiler to move downward, and the boiler is placed in the right position, and the connection between the boiler and the hanging assembly 8 can be removed, and the boiler is installed.
