Description

Track type device for preventing falling from high altitude

Technical field

The utility model relates to a kind of high-altitude working safety device, specifically a kind of track type device for preventing falling from high altitude.

Background technique

It is all be unable to do without operation of ascending a height in the fields such as shaft tower and building in electric power power transmission and transformation line shaft tower, substation framework, communication, In recent years, electric power development fast speed also requires safety management level higher and higher, the task of power grid construction and transformation Also increasingly heavier, a large amount of construction, service work task are directed to operation of ascending a height, for the peace for solving current a large amount of high altitude operation There are various types of anti-fall devices currently on the market in full problem, and anti-fall device includes catching device and guide rail, passes through catching device With being used cooperatively for guide rail, preferably solve the problems, such as the safe fall-proof of high altitude operation, however, these anti-fall devices there is also Complicated defect.

Utility model content

The purpose of the utility model is to overcome prior art defect, provide that a kind of structure is simpler, safe and reliable Track type device for preventing falling from high altitude.

In order to achieve the goal above, the utility model uses a kind of following technical scheme: track type device for preventing falling from high altitude, it is special Sign is: including anti-fall pedestal and swing rod and dynamic clamping head and quiet clamping head, the anti-fall substantially rectangular in cross section body of pedestal, top is along its length Centre is slightly arched upward, and downside is equipped with the guide groove of perforation to both ends along its length, the position in the corresponding portion that arches upward in the middle part of the guide groove Equipped with the swing rod cavity being connected with guide groove, pendulum shaft is equipped in the swing rod cavity of the top of guide slot in the width direction, it is described The portion of arching upward of anti-fall pedestal is equipped with the window being inserted into for swing rod, and described swing rod one end is dog point, and the dog point, which is equipped with, to be protruded Brake tooth, the other end is hooking end, and the dog point is equipped with axis hole with pendulum shaft clearance fit, and the swing rod passes through braking Axis hole and pendulum shaft cooperation on end are pivotably connected between the first position and the second position on the anti-fall pedestal, Under the state of first position, the brake tooth is in except guide groove, under the state of the second position, the brake tooth be in guide groove it In, the dynamic clamping head and quiet clamping head applies the elastic force of a trend first position to swing rod.

The utility model has the beneficial effects that: this track type device for preventing falling from high altitude includes that anti-fall pedestal and swing rod and elasticity are multiple Position part, described swing rod one end is dog point and is equipped with brake tooth outstanding, and the swing rod is pivotably connected in the anti-fall seat On body, when falling accident occurs, the swing rod is swung under the gravity of human body, so that the brake tooth on dog point It is stuck in guide groove on guide rail and prevents further tenesmus, have the function that safeguard protection, and structural member is less, structure is more Add simple.

The utility model is described in further detail with reference to the accompanying drawing.
