Detailed Description
The technical solution of the present invention will be described below with reference to the accompanying drawings and examples.
Referring to fig. 1 to 5, the anti-falling device for a climbing frame guide rail 1 according to this embodiment is sleeved on the outer side of the guide rail 1, the cross section of the guide rail 1 is T-shaped, the anti-falling device includes a mounting base 2 fixed on a wall, a chute 3 for accommodating the guide rail 1 is provided on the mounting base 2, the cross section of the chute 3 is T-shaped, so that the guide rail 1 can slide in the chute 3, a plurality of node holes 4 are provided at an upper and a lower interval on the inner side surface of the guide rail 1, a brake block 5 capable of extending into the node holes 4 is hinged on the mounting base 2, the brake block 5 is located on the inner side of the chute 3, a brake pin 6 is further provided in the mounting base 2 for limiting the maximum rotation angle of the brake block 5, the brake block 5 exactly pushes against the brake pin 6 when rotating to a horizontal position, and the brake block 5 extends into the node holes 4 to brake the guide rail 1, the brake block 5 is also hinged with a control block 7, the control block 7 is arranged on the outer side of the brake block 5, the control block 7 can rotate in a certain angle range relative to the control block 7, and under the normal state, the brake shoe 5 is vertically aligned and does not interfere with the pitch bore 4, at which point the control block 7 extends into the pitch bore 4, when the guide rail 1 moves up and down at normal working speed, the nodal hole 4 pushes the control block 7 to swing, the control block 7 pushes the brake block 5 to swing, and the swing amplitude of the brake block 5 is not enough to interfere with the pitch hole 4, when the guide rail 1 moves up and down, the brake block 5 and the control block 7 swing simultaneously, so that the control block 7 moves from one nodal hole 4 to another nodal hole 4, so that the guide rail 1 can smoothly move up and down, in order to make the control block 7 and the brake block 5 smoothly separate from the joint hole 4, the front ends of the control block 7 and the brake block 5 are provided with arc surfaces.
