Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.

As shown in figures 1 to 4, the anti-falling device comprises an anti-falling rear swing block 1, an anti-falling block 2 and an anti-falling small swing block 3; the anti-falling rear swing block 1 is a square block with an arc-shaped notch 4 at the lower right corner; the middle part of the upper end surface of the anti-falling block 2 is provided with a convex block 5, and the convex block 5 is hinged with the upper right corner of the anti-falling block 2; the anti-falling block 2 can swing left and right in the arc-shaped notch 4 of the anti-falling rear swinging block 1; a groove 6 is arranged inside the anti-falling block 2, and the anti-falling small swinging block 3 is arranged inside the groove 6; the anti-falling block 2 is provided with an anti-falling pin 7 which penetrates through the anti-falling block 2 and the anti-falling small swinging block 3; the anti-falling block 2 and the anti-falling small swinging block 3 can rotate along the pin; a torsion spring 8 arranged between the anti-falling small swing block 3 and the anti-falling block 2 is arranged in the groove 6.

In order to realize the installation of the torsion spring 8, the anti-falling block 2 is provided with a positioning pin 9 which runs through the anti-falling block 2, the torsion spring 8 is sleeved on the positioning pin 9, two ends of the torsion spring 8 respectively support against the side wall of the groove 6 and the anti-falling small swinging block 3, so that the anti-falling small swinging block 3 can rotate and reset clockwise relative to the anti-falling block 2.

In order to limit the rotation angle of the anti-falling block 2, a first fixed block 10 positioned above the anti-falling rear swinging block 1 and a second fixed block 11 positioned below the anti-falling block 2 are arranged on a guide support for mounting the anti-falling device.

In order to realize better anti-falling and supporting, when the anti-falling block 2 is locked, the upper end surface of the anti-falling block 2 is inclined upwards.

When the utility model is used, firstly, the anti-falling pin 7 is arranged on the guide support through the anti-falling device; when the anti-falling device is installed, the anti-falling pin 7 directly penetrates through the guide support and the anti-falling block 2; so that the anti-falling block 2 can be swung.

Meanwhile, the positions of the first fixing block 10 and the second fixing block 11 are reasonably arranged on the guide support, so that the anti-falling swing block 1 can be fixed by the first fixing block 10 when swinging to the upper end surface level; meanwhile, the lower end of the falling prevention block 2 can be blocked by the second fixed block 11; therefore, the swing position of the anti-falling block 2 is limited, and the limiting block is prevented from excessively rotating clockwise.

The falling protector is mainly matched with a cross rod 13 on a guide rail 12, so that the limiting is realized.

The specific working process is as follows:

when the guide rail 12 needs to be lifted, referring to fig. 4.a, the cross rod 13 on the guide rail 12 can stir the anti-falling small swing block 3, so that the anti-falling small swing block 3 rotates anticlockwise. Because the anti-falling small swing block 3 is arranged inside the anti-falling block 2 and the torsion spring 8 is arranged between the anti-falling small swing block 3 and the anti-falling block 2, the anti-falling block 2 can also rotate anticlockwise. Meanwhile, the anti-falling block 2 and the anti-falling rear swinging block 1 are in a hinged relationship, and the anti-falling block 2 is arranged in the arc-shaped notch 4 of the anti-falling rear swinging block 1; therefore, the anti-falling block 2 swings anticlockwise to drive the anti-falling rear swing block 1 to rotate anticlockwise, so that the cross rod 13 is given, and the guide rail 12 rises.

When the guide rail 12 is accidentally descended, the cross rod 13 on the guide rail 12 moves downwards as shown in fig. 4.b and 4.c, and directly touches the right end of the anti-falling block 2, and the right end of the anti-falling block 2 protrudes rightwards; at the moment, the cross rod 13 can drive the anti-falling block 2 to rotate clockwise, and the anti-falling block 2 is limited by the second fixed block 11, and the anti-falling swinging block 1 is limited by the first fixed block 10; the entire safety brake can therefore only be rotated into the position according to fig. 4. c. The right end of the anti-falling block 2 can play a role in supporting the cross rod 13. The whole guide rail 12 and the climbing frame can not fall down, and the anti-falling function is achieved.

The anti-falling device is characterized in that the anti-falling block 2 and the anti-falling rear swinging block 1 are hinged; the anti-falling block 2 is arranged at the arc-shaped notch 4 of the anti-falling rear swinging block 1; therefore, when the anti-falling block 2 rotates clockwise, the left side of the anti-falling block 2 can abut against the arc-shaped notch 4, so that the clockwise rotation angle of the anti-falling block 2 relative to the anti-falling rear swinging block 1 is limited; furthermore, the first fixing block 10 is used for limiting the anti-falling rear swinging block 1, so that the limiting of the anti-falling block 2 is realized. Meanwhile, due to the design of the anti-falling rear swing block 1, the compressive strength of the anti-falling block 2 is greatly improved; the situation of fatigue fracture of the anti-falling block 2 caused by only relying on the anti-falling block 2 is avoided.

In the device, the anti-falling small swing block 3 is arranged inside the anti-falling block 2; the anti-falling block 2 and the anti-falling lower swing block can swing relatively, so that when falling is prevented, the two adjacent cross rods 13 can be respectively matched with the anti-falling small swing block 3 and the anti-falling block 2, and referring to fig. 4.b, namely, the cross rod 13 at the lower part can stir the anti-falling small swing block 3 to rotate along the pointer and drive the anti-falling block 2 to rotate clockwise, so that the right end of the anti-falling block 2 can better support the cross rod 13 at the upper part; the falling prevention success rate is effectively improved, and the situation that the falling prevention block 2 cannot reset due to dead weight and cannot prevent falling is avoided.
