Wherein the rotary limiter controls the turns (angles) of the tower crane rotating leftwards and rightwards, thereby preventing the cable from being twisted and damaged;
the universal slewing limiting device is invented in order to solve the problems that the types of the tower cranes are different, the heights of the upper supports are different, the center distances of the tower cranes are different due to the difference of slewing bearings, the existing slewing limiting devices are various, the positions of the existing slewing limiting devices are always required to be welded on site, the production efficiency is low for manufacturing and delivery, and delivery is easy to be wrong.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve the problem that above-mentioned exists, designed a general type gyration stop device.
In order to realize the technical purpose, reach above-mentioned technological effect, the utility model discloses a realize through following technical scheme:
a universal type rotation limiting device comprises a rotation limiting device, a connecting sleeve, a telescopic rod, a fixing frame, a second connecting plate and an upper support;
the left side wall of mount is equipped with connecting plate one, the gyration stopper passes through the bolt and sets up on the mount, adapter sleeve sets up on the output shaft of gyration stopper below, a plurality of perpendicular holes have been seted up to adapter sleeve's outer wall, telescopic link upper portion extends into in the adapter sleeve, can stretch out and draw back and remove, and fixed through the split pin, the telescopic link is located the connecting hole one that the mount bottom was seted up, and rotates through connecting hole one, the right side wall of upper bracket is equipped with connecting plate two, the outer wall of connecting plate one and connecting plate two all is equipped with connecting hole two, pass connecting hole two through the bolt between connecting plate one and the connecting plate two and fix.
Furthermore, the second connecting hole is a transverse long hole.
Further, a plurality of the vertical hole gaps are arranged on the outer wall of the connecting sleeve.
The beneficial effects of the utility model are that:
the utility model discloses gyration stop device can realize about the regulation, can realize general type at different grade type tower machine use, and mass production improves production efficiency for the company, reduces manufacturing cost.
