Abstract

The invention provides a tower crane position limiter structure which comprises a shell, pressing plates, a bolt, a rubber ring, a screw rod, a guide rod, a movable nut, a bearing, a screw plug, an end cover, a limiting switch, screws and a nut. The pressing plates and the guide rod are arranged in the shell. The movable nut in the shell is arranged on one side of the guide rod, and one end of the movable nut is located on one side of the nut. The bolt is arranged at one end of the shell, and the rubber ring on one side of the bolt is arranged at the top end of the shell. One end of the screw rod is arranged in the end cover, and the end cover is arranged at one end of the shell. The limiting switch is arranged in the shell and is closely connected through the screws. The structure is stable and close in connection, and the tower crane position can be effectively limited by the limiting switch. Work efficiency is improved, use is facilitated, the service life is long, good social effects and economic benefits are achieved, and the structure is suitable for being used and popularized.

Description

technical field [0001] The invention relates to a tower crane position limiter, in particular to a tower crane position limiter structure, which belongs to the field of mechanical technology. Background technique [0002] A limit switch is an electrical switch used to limit the movement limit position of a mechanical device. There are contact and non-contact limit switches. The contact type is more intuitive. The upper travel switch is installed on the moving parts of the mechanical equipment, and the limit position stopper is installed on the fixed point of the relative movement, or the opposite installation position. When the mechanical contact of the limit switch hits the stopper, the control circuit is cut off, and the machine stops or changes its operation. Due to the mechanical inertial movement, this limit switch has a certain "overtravel" to protect the switch from damage. There are many forms of non-contact, the common ones are reed switch, photoelectric type, in...
