Detailed Description

The technical solution of the embodiment of the present invention will be described below with reference to the accompanying drawings.

Examples

As shown in fig. 1, the high fall prevention guardrail comprises a guardrail frame 1 for shielding an elevator entrance, wherein the guardrail frame 1 comprises a first vertical rod 101 and a second vertical rod 102 which are parallel to each other. Two parallelogram hinges 2 for extending the length of the guardrail frame 1 are rotatably connected between the first vertical bar 101 and the second vertical bar 102. First montant 101 passes through the bolt fastening in the outer vertical one side of elevator mouth, and the lower extreme of second montant 102 rotates and is connected with gyro wheel 16, and second montant 102 and first montant 101 relative slip to can slide towards the outer vertical opposite side of elevator mouth, be used for sheltering from completely the elevator mouth. The safety rope sliding groove 3 is fixedly arranged above the guardrail frame 1 on the elevator opening and along the moving direction of the second vertical rod 102 through bolts, and the arc-shaped groove 4 is welded and communicated at one end of the safety rope sliding groove 3 far away from the first vertical rod 101. In this embodiment, safety rope spout 3 and arc 4 are the T font for the one end of the safety rope slider that the constructor binded can be embedded into safety rope spout 3 and arc 4, and can not take place to break away from.

Referring to fig. 1 and 2, the lower end of the arc-shaped groove 4 is welded with a third vertical rod 9 parallel to the second vertical rod 102, and a magnet 10 magnetically connected with the second vertical rod 102 is arranged on one side of the third vertical rod 9 close to the second vertical rod 102 along the length direction of the third vertical rod. An infrared alarm lamp 11 is installed on the third vertical rod 9, the infrared alarm lamp 11 is electrically connected with a control switch 12 used for controlling the opening and closing of the infrared alarm lamp 11, the control switch 12 is installed on one side, close to the second vertical rod 102, of the third vertical rod 9, and a second abutting rod 13 used for abutting against the control switch 12 is welded on the second vertical rod 102.

Referring to fig. 1 and 2, a wedge block 5 for shielding the opening of the arc-shaped groove 4 is vertically and slidably connected to one end of the arc-shaped groove 4 close to the second vertical rod 102, and a sleeve 7 for sliding the wedge block 5 is welded on the arc-shaped groove 4. One end of the second vertical rod 102, which is close to the wedge-shaped block 5, is welded with a first abutting rod 6 which is abutted against the wedge-shaped block 5, and the first abutting rod 6 is abutted against the wedge-shaped block 5 to push the wedge-shaped block 5 to slide upwards to open the opening of the arc-shaped groove 4. The first abutting rod 6 penetrates through the sleeve 7 to abut against the wedge-shaped block 5, and a spring 8 (see fig. 3) for abutting against the wedge-shaped block 5 is arranged in the sleeve 7.

As shown in fig. 4, the communicating part of the arc-shaped groove 4 and the safety rope sliding groove 3 is rotatably connected with a baffle 14 for blocking the arc-shaped groove 4 and the safety rope sliding groove 3, one end of the baffle 14 is hinged with the arc-shaped groove 4, a torsion spring 15 is arranged at the rotating connecting part of the baffle 14 and the arc-shaped groove 4, and the baffle 14 is far away from the end rotatably connected with the arc-shaped groove 4 and is abutted to the arc-shaped groove 4.

The specific working process is as follows: when being under construction to the elevator mouth, constructor wears to establish the entering from the opening part of arc wall 4 with the one end that self was binded safety rope on one's body earlier to slide to baffle 14 department along arc wall 4, and continue to slide, make baffle 14 rotate, and make safety rope's slider one end enter into safety rope spout 3 in, baffle 14 automatic re-setting under torsional spring 15's effect.

Afterwards, constructor pulls second montant 102 towards first montant 101 and moves, and the first pole 6 that supports that is connected with wedge 5 breaks away from the butt with wedge 5, and wedge 5 slides along the length direction orientation of sleeve 7 under the effect of spring 8 to shelter from the opening of arc groove 4. Meanwhile, in the process, the second abutting rod 13 is separated from the control switch 12 on the third vertical rod 9 in an abutting mode, the infrared alarm lamp 11 is normally on, after constructors enter the elevator entrance construction, the second vertical rod 102 is pulled towards the third vertical rod 9, and the second vertical rod 102 is magnetically connected with the magnet 10 on the third vertical rod 9. Meanwhile, the second abutting rod 13 abuts against the control switch 12, and presses the control switch 12 to control the infrared alarm lamp 11 to be turned off.

When the constructor finishes the construction and needs to come out of the elevator port, the constructor pulls the second vertical rod 102 to move towards the third vertical rod 9 and come out of the elevator port. At this time, the infrared alarm lamp 11 lights up, and the wedge block 5 shields the opening of the arc-shaped groove 4. The constructor rotates the baffle 14 to slide one end of the slide block of the safety rope into the arc-shaped groove 4 from the safety rope slide groove 3. Because of the blocking of the wedge-shaped block 5 and the fact that one end of the safety rope slider cannot slide out of the arc-shaped groove 4, the constructor must pull the second vertical rod 102 towards the third vertical rod 9 to block the elevator opening. After the first block and the wedge 5 of supporting carry out the butt to when second montant 102 continued to drive first pole 6 of supporting and moved towards wedge 5, make wedge 5 upwards slide under the effect of the butt of first pole 6 of supporting, make wedge 5 no longer shelter from the opening of arc groove 4, thereby make constructor can take out the slider one end of safety rope from the arc groove 4. And the second support rod 13 is abutted with the control switch 12 to control the infrared alarm lamp 11 to be turned off, and the magnet 10 on the third vertical rod 9 is magnetically connected with the second vertical rod 102 to fix the position of the second vertical rod 102.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
