The top end of the screw rod 34 is coaxially provided with the hand wheel 33. The nut 35 is located between the upper moving frame 31 and the lower moving frame 32 in the height direction and is threadedly arranged on the screw rod 34.

[0039] The two ends of the cross rod 11 are detachably arranged between the top portions of the pair of movable support rods 13 through bolts.

[0040] The pair of bottom support rods 12 of each side support leg are placed on the ground through the bottom end of the foot cup 121.

[0041] The tobacco warehouse gantry support frame is put into the tobacco production line, which is not only height-adjustable but also convenient to move. The operation mode can be referred to as follows:

[0042] 1. When the height of the cross rod of the support frame body, i.e., the working height of the gantry support frame, is adjusted through the height adjustment assembly, the following steps are included:

[0043] Step one: unlocking the movable support rod before adjustment

[0044] The movable support rod on each side is held and rotated by the rocker, which is pulled through the locking link mechanism to drive the locking pin to slide upward along the guide hole of the guide block until the locking pin is separated from the locking groove of the positioning pin, thereby releasing the constraint of the positioning pin. Then the positioning pin can be pulled out along the positioning channel. The rocker can be kept in the current state, the locking spring is deformed, and the current height position of the locking pin is maintained.

[0045] Step two: adjusting the height position of the movable support rod

[0046] The height position of the movable support rod is adjusted again by relying on external force to lift or lower the movable support rod to approximately reach the required working height, and then the height position of the movable support rod is finely adjusted so that the perforation of the closest positioning hole below the current height position is aligned with the positioning hole. Then the positioning pin is inserted again.

[0047] Step three: relocking the movable support rod after adjustment

[0048] Rotating the positioning pin, the positioning hole carried by the positioning pin is upwardly and vertically aligned with the guide hole of the guide block, then the rocker is loosened, under the elastic force of the locking spring, the locking pin is driven to slide downward along the guide hole of the guide block through the locking linkage mechanism, until the locking pin is inserted into the locking groove on the positioning pin, thereby the positioning pin is locked again.

[0049] 2. The whole gantry support frame is movable through the moving assembly, and the implementation is as follows:

[0050] By rotating the hand wheel forward or reversely, the screw rod is rotated, the nut is vertically lifted or lowered along the screw rod through the rotation of the screw rod, thereby the lifting boom is synchronously lifted or lowered, until the lifting boom is lifted to the position that the rollers are separated from the ground, at this time the gantry support frame can be placed on the ground, or the lifting boom is lowered to the position that the rollers contact the ground, and the bottom support rod is lifted to the position that the foot cup carried by the bottom support rod is separated from the ground, at this time the gantry support frame can be moved on the ground through the rollers of the moving assembly.

[0051] Although the embodiments of the utility model have been shown and described, those skilled in the art can understand that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and purposes of the utility model, the scope of the utility model is defined by the claims and its equivalents.
