Embodiment Construction

[0020] Such as figure 1 As shown, in the preferred embodiment of the present invention, the anti-uncontrollable overturning elevating pole erecting mechanism includes a cylinder base 300 , an elevating pole 100 , a pneumatic pushing mechanism, a telescopic shaft 310 , a rotating shaft 420 and a base 400 .

[0021] Wherein, there is a horizontal through hole 320 in the middle of the cylinder block 300; the base 400 includes a horizontal plate fixed on the ground and two vertical plates parallel to each other and vertically fixed on the horizontal plate, the upper ends of the vertical plates are the same There are holes in the positions; the rotating shaft 420 passes through the through hole 320 and both ends are inserted into the holes of the vertical plate of the base 400. After being installed through a certain positioning structure, the rotating shaft 420 can be wound around its horizontal position in the hole of the vertical plate. The central axis rotates, and at the same ...

Abstract

The invention relates to a lifting rod standing mechanism for preventing out-of-control overturning, which comprises a cylinder seat (300), a lifting rod (100) which is arranged on the cylinder seat (300) and can be lifted, a horizontal revolving shaft (420) which passes through the cylinder seat (300) and a base (400) which is sleeved on the revolving shaft (420). The revolving shaft (420) is rotated to drive the cylinder seat (300) and the lifting rod (100) to rotate and erect; the lifting rod standing mechanism also comprises a pneumatic pushing mechanism and a telescopic shaft (310) whichis positioned on the side face of the cylinder seat (300); a limit hole (410) which is matched with the telescopic shaft (310) is reserved on the side of the base (400); and the pneumatic pushing mechanism controls the telescopic shaft (310) to enter / retreat from the limit hole (410). The lifting rod standing mechanism adds a limit to the lifting rod by adding the pneumatic pushing mechanism, so that the lifting rod can be prevented from out-of-control overturning when the positioning of the revolving shaft is ineffective, and an accident is effectively avoided; and meanwhile, the lifting rodstanding mechanism has the advantages of simple structure, increased reliability without adding any operation, better safety and better rationality.

Description

technical field [0001] The invention relates to a safety improvement structure of an air cylinder, and more specifically relates to an elevating rod erecting mechanism for preventing out-of-control overturning. Background technique [0002] The lifting rod is a commonly used pneumatic lifting device, which can gradually rise with the increase of the bottom air pressure, thereby jacking up heavy objects. This lifting rod structure for realizing pneumatic lifting usually includes a lifting rod, a cylinder liner sleeved on the outside of the lifting rod, and a cylinder seat mounted on the bottom of the cylinder liner. The surface of the cylinder seat is sealed with the bottom surface of the cylinder liner, and an air chamber is formed at the bottom of the lifting rod. An air path is set in the cylinder block so that the compressed gas of the external air pump can enter the air chamber through the air path to inflate or deflate the air chamber, and the lifting rod can be forced...
