Preferably, described keep plate is hinged on body by rotating shaft, and described rotating shaft passes from body both sides to be connected with respectively and is arranged symmetrically with and with the Connection Block of safety belt connecting hole, described safety belt connecting hole and rotating shaft are arranged in track runner both sides.Said structure is in the time that staff falls, and the contact-making surface relative orbit of described keep plate and track moves downward.
In order to improve the braking effect of keep plate, preferred, described keep plate is provided with and contacts the first anti-slop serrations coordinating with track.Described the first anti-slop serrations can increase frictional force, thereby prevents slippage in the time that keep plate and track brake push against, thereby improves security.
A kind of cage dog of high altitude, comprises above-mentioned track self-locking device, the safety belt being connected with track self-locking device, and stretch into the track of track runner, the both sides of described track push against and coordinate with roller and elastic supporting mechanism respectively.
Preferably, on described keep plate and track, be respectively equipped with the first anti-slop serrations and the second anti-slop serrations that cooperatively interact.
Further preferred, relative the second anti-slop serrations retaining of described the first anti-slop serrations coordinates.Described retaining fit structure is that, when body moves up along track, relative the second anti-slop serrations of the first anti-slop serrations of keep plate can move upward; But when body moves down along track, or falling accident occurs, now relative the second anti-slop serrations motion of the first anti-slop serrations moves downward, can be stuck.
The beneficial effects of the utility model:
Track self-locking device of the present utility model and cage dog of high altitude, by the roller and the elastic supporting mechanism that push against are set respectively in track both sides, thereby make body relative orbit stable mobile, the excessive and stuck problem of avoiding occurring rubbing between body and track.
