Detailed Description

The present invention will be further described with reference to the accompanying drawings so as to facilitate the understanding of the present invention by those skilled in the art.

As shown in fig. 1, a novel speed difference safety hook for climbing frame comprises: the anti-falling device comprises an anti-falling stop block (3), a compression return spring (4), a spring positioning shaft (5), a pulling block rotating shaft (6), a pulling block (7), a pulling block return spring (8) and a bracket (9); the novel speed difference falling protector for the climbing frame is fixed on a building through a support (9), a spring positioning shaft (5) is fixed on two perforated plates in the middle of the support (9), a compression reset spring (4) is installed on the spring positioning shaft (5) and can be stretched along the spring positioning shaft (5), the section of the upper end of a falling-preventing stop block (3) is rectangular-like, the lower part of the front end of the falling-preventing stop block is chamfered, a stress plate is fixed at the lower end of the falling-preventing stop block (3) and is connected to the spring positioning shaft (5) and can move along the spring positioning shaft, a pull block (7) is L-shaped and is installed on a pull block rotating shaft (6) and can rotate along the pull block, the upper end of the pull block (7) contacts with the rear end of the stress plate of the falling-preventing stop block (3), the lower end of the pull block (7) extends out of the front end of the support (9), and the rear end of the pull block reset spring (8) is fixed on, the front end is connected with the pulling block (7).

The anti-falling working principle is as follows:

when the climbing frame rises, as shown in fig. 1, the upper transverse rod (2) of the guide rail (1) moves upwards to push the pulling block (7) to rotate clockwise around the rotating shaft (6), at the moment, the other end of the pulling block (7) is separated from the anti-falling stop block (3), and the anti-falling stop block (3) does not move; when the crosspiece rod (2) crosses the extreme position of the pulling block (7), as shown in fig. 2, the pulling block return spring (8) pulls the crosspiece rod back to return, and the lifting operation is completed by reciprocating in this way.

When the climbing frame descends, as shown in figure 3, the guide rail cross rod (2) moves downwards to push the pulling block (7) to rotate anticlockwise around the rotating shaft (6), at the moment, the other end of the pulling block (7) is pressed tightly to push the anti-falling stop block (3) to extend outwards to the space between the two transverse stop rods (2); as shown in figure 4, when the transverse rod (2) exceeds the limit of the rotation of the pulling block (7), the pulling block (7) is rapidly returned due to the action of the pulling block reciprocating spring (8), the other end of the pulling block is separated from the anti-falling stop block (3), at the moment, the anti-falling stop block (3) rapidly retracts under the action of the compression reciprocating spring (4) due to the loss of the thrust action, and the transverse rod (2) on the guide rail (1) can continuously move downwards due to the slow descending speed of the guide rail (1) and the fast retracting speed of the anti-falling stop block (3) by utilizing the relative speed difference.

When the climbing frame rapidly falls in an emergency, as shown in fig. 5, the anti-falling stop block (3) is pressed and clamped by the rail crosspiece rod (2) before retracting, and the climbing frame rail (1) is clamped and cannot continuously fall by the reaction force of the bracket (9), so that the safety protection effect is achieved.

The utility model discloses under the technical scheme scope circumstances, usable the utility model discloses the technical scheme who explains makes multiple change, all should be contained in all equivalent changes that do not break away from this scheme shape, structure and principle the utility model discloses a protection scope.
