Fig. 2 shows a schematic structural view of the reel lifting support device provided by the utility model. The reel lifting and supporting device 10 comprises a first telescopic part 11 and a second telescopic part 12 which are connected together in an adjustable length mode. As shown in fig. 1, the first telescopic member 11 is hinged to the reel mechanism 20, the second telescopic member 12 is hinged to the header mechanism, and the reel lifting support device 10 is used for supporting the reel mechanism 20 and adjusting the height of the reel mechanism 20.
As shown in fig. 1 and 2, in an embodiment of the present invention, the second telescopic member 12 has a cavity, one end of the second telescopic member 12 is hinged to the header mechanism 30, and the other end is an opening communicated to the cavity inside. One end of the first telescopic member 11 is hinged to the reel mechanism 20, and the other end thereof extends into the cavity of the second telescopic member 12 to form a telescopic mechanism so as to adjust the height of the reel mechanism 20. Specifically, a plurality of holes which are matched with each other are arranged on the first telescopic part 11 and the second telescopic part 12, and the first telescopic part 11 and the second telescopic part 12 are fixedly connected at a certain length through the split pin 13 by penetrating through the corresponding holes on the first telescopic part 11 and the second telescopic part 12 through the pin shaft 13 according to the actual height requirement on the reel mechanism 20.

Specifically, as shown in fig. 3 and 4, the first telescopic member 11 has at least 3 holes, for example, 5 holes, and the adjacent holes are spaced by 25 mm. The second telescopic member 12 has 2 holes, and the adjacent holes are 37.5mm apart. Each hole position on the first telescopic part 11 is matched with one of the two hole positions on the second telescopic part 12 in sequence, and then the pin shaft 13 is installed, so that each section position is adjusted by 12.5mm, the length of each section position under the equal hole position condition is half of the distance between the adjacent holes of the first telescopic part 11, and therefore small fluctuation of each section position of length adjustment is achieved.
The pin shaft and the split pin are standard parts, the first extensible part 11 is cut by adopting a steel plate, and the second extensible part 12 is a welding part and can be welded with the cut steel plate after the steel pipe is punched.
