Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

The track braking anti-falling device comprises a fixing bolt 1, a track 2, a slide block 3, a fixing buckle 4 and a safety rope 5, wherein the track 2 is of a plate-shaped structure with a rectangular cross section, a plurality of positioning bolts 1 are uniformly distributed on the side surface of the track 2, the positioning bolts 1 are uniformly distributed along the axis direction of the track 2 and are vertical to the axis of the track 2, the track 2 is connected with the outer side surface of an external climbing device 6 through the fixing bolts 1, the track 2 and the axis of the external climbing device 6 are distributed in parallel, a plurality of ratchets 7 are uniformly distributed on the front end surface of the track 2, a plurality of arc braking guide surfaces 8 are uniformly distributed on the rear end surface, each arc braking guide surface 8 is positioned between two adjacent ratchets 7, the included angle of 30-60 degrees is formed between the axis of each ratchet 7 and the axis of the track 2, the front end surface 8 of each ratchet is at least 5 mm higher than the front, slider 3 is rectangle massive structure, and its rear end face is established and is led spout 31 and dodge groove 32, and the groove 32 intercommunication each other is dodged to direction spout and 31, and distribute along 3 axis directions of slider, and direction spout 31 and dodge groove 32 and constitute jointly that the cross section is "T" style of calligraphy trough-shaped structure, slider 3 through leading spout 31 cladding outside track 2 and with track 2 mutual sliding connection, dodge groove 32 axis and 1 axis of fixing bolt perpendicular and crossing, the fixed knot 4 is connected with 3 side surfaces of slider, and be located and be close to 3 up end positions of slider department, the fixed knot 4 axis and 3 axis vertical distribution of slider, interconnect between fixed knot 4 and safety rope 5.

In the concrete implementation of the novel aerial work platform, the rail is connected with the side surface of the rail for aerial work through the positioning bolts, and the rail is distributed in parallel with the rail.

The rail is provided with a unidirectional ratchet, and the rail can be fixed at the edge of equipment such as a ladder, a climbing frame and the like and can be fixed at the position of a bolt. The direction of the ratchet is different from the direction of the gravity. In addition, the middle rail allows the two rails to form a certain angle when being spliced, so that various installation environments are facilitated, and corners are facilitated.

The middle of the sliding block is provided with a guide sliding groove and an avoiding groove which pass through the rail, and the sliding block is connected with the rail, so that the movement of the sliding block can not be influenced due to the unidirectional property of the ratchets on the rail in the ascending process, and the operator can climb upwards conveniently. In the descending process, an operator pulls the safety rope after descending for a certain distance to enable the sliding block to fall.

When falling, the safety rope is pulled in the falling process, the slider is forced to be unbalanced to rotate due to the fact that the fixing buckle is arranged on the single side of the slider, the slider is guided by the arc braking guide surface of the rear end face of the rail in the falling process, the slider moves in an S shape, and the lower end face of the slider is smoothly abutted to the ratchet wheel of the front end face of the rail, so that braking is performed.
