The vertical hoisting device provided by the utility model comprises five parts, namely a hoisting driving part, a telescopic support, an upright post 1, a secondary beam 2 and a main beam 3, and can be temporarily assembled in a space-limited occasion; the main beam 3 can adopt H-shaped steel, the secondary beam 2 and the upright post 1 can adopt square steel pipes, and flange plates are welded at the upper end and the lower end of the upright post 1; the telescopic support is formed by welding square steel, can be extended or contracted, and is favorable for carrying in occasions with limited space.

Retractable support quantity in this scheme is two, and every retractable support top is equipped with two stands 1, is equipped with a time crossbeam 2 between two stands 1, is equipped with draw-in groove 2.1 on the time crossbeam 2, and main beam 3 places in draw-in groove 2.1, all is equipped with the bolt hole on draw-in groove 2.1 and the main beam 3, passes through the bolt fastening between draw-in groove 2.1 and the main beam 3. The upright column 1 is connected with the telescopic support through a flange plate, and the upright column 1 is connected with the secondary cross beam 2 through a flange plate.

The first cross bar 10 is inserted into the second cross bar 11; a first sliding groove 13 is formed in the first cross bar 10, a second sliding groove 14 is formed in the second cross bar 11, limiting grooves 15 are formed in two ends of the first sliding groove 13, and one end of the second sliding groove 14 is provided with the limiting groove 15; the limiting piece 12 comprises a sliding rod 12.1, a limiting piece 12.2 is arranged on the sliding rod 12.1, and the limiting piece 12.2 is used for being matched with the limiting groove 15. The first cross bar 10 and the second cross bar 11 are square steel pipes. The reason why the first cross bar 10 and the second cross bar 11 are not connected by bolts is that: the bolts easily slide between the first and second

sliding grooves

13 and 14, and if the bolts are excessively tightened to improve the connection stability, the first and

second rails

10 and 11 may be deformed. Therefore, the limiting member 12 with a limiting function is adopted to be matched with the first sliding chute 13, the second sliding chute 14 and the limiting groove 15.

The sliding rod 12.1 is provided with an external thread 12.3, and the external thread 12.3 is connected with a screw cap 12.4. The upper end and the lower end of the sliding rod 12.1 are respectively provided with an upper baffle 12.5 and a lower baffle 12.6.

The operation principle of the limiting member 12 is as follows:

the rotary nut 12.4 is used for adjusting the height of the limiting plate 12.2, when the limiting plate 12.2 is separated from the limiting groove 15, the relative positions of the first cross rod 10 and the second cross rod 11 can be adjusted, the first cross rod 10 and the second cross rod 11 are in a contracted state when being superposed, and the first cross rod 10 and the second cross rod 11 are completely unfolded to be in an unfolded state;

as shown in fig. 7, when the nut 12.4 rotates upward and disengages from the external thread, the sliding rod 12.1 falls, the limiting plate 12.2 falls, the upper baffle 12.5 is the supporting point of the whole limiting member 12, and the limiting plate 12.2 disengages from the limiting groove 15;

as shown in fig. 8, the first rail 10 is retracted.

As shown in fig. 9, the slide bar 12.1 is raised upward by rotating the nut 12.4, and when the lower catch 12.6 contacts the second rail 11, it is rotated to a position where the position-limiting plate 12.2 is located in the position-limiting groove 15.
