If highly heighten after in order to solve current independent scaffold, when the workman was put up the scaffold, workman's safety was difficult to the problem of assurance, the utility model provides a frame is climbed to steel construction safety, as shown in fig. 1 to fig. 3.

The steel structure safety climbing frame comprises a climbing frame body 1, wherein a riding track for people to walk is arranged on the climbing frame body 1, a protective guard 6 is arranged on one side of the riding track, an upper escalator 2 and a lower escalator 2 are arranged on the outer side of the climbing frame body 1, a ratchet bar 3 which is vertically arranged is arranged on the upper escalator 2 and the lower escalator 2, and a falling prevention device 4 is arranged on the ratchet bar 3; the anti-falling device 4 comprises a mounting seat 4a which is arranged on the ratchet bar 3 in a sliding manner, a plurality of guide wheels 4f are arranged on the mounting seat 4a and roll along the ratchet bar 3, and dampers are arranged on the guide wheels 4 f;

a claw 4b is arranged in the mounting seat 4a, the near end of the claw 4b is hinged on the mounting seat 4a, a pawl 4c is fixed at the far end of the claw 4b, and the pawl 4c is matched with the ratchet bar 3 to lock the downward movement of the claw 4 b; the claw 4b is connected with an elastic piece 4i for bouncing the far end of the claw 4b away from the ratchet bar 3; a safety rope 4d is fixed at the proximal end of the jaw 4b, the safety rope 4d is wound around the distal end of the jaw 4b, when the safety rope 4d is tightened, the distal end of the jaw 4b presses the ratchet bar 3, and the tail end of the safety rope 4d is connected to the body of a user.

At the during operation, the utility model discloses in mainly set up anti-falling device 4 in the upper and lower staircase 2 position of climbing the frame, then link to each other with the personnel of upper and lower staircase 2 with safety rope 4d on the anti-falling device 4, avoid personnel to drop. Specifically, when the person drops, the safety rope 4d can pull the whole anti-falling device 4 to move downwards quickly to cause the guide wheel 4f to rotate at a high speed, the guide wheel 4f is provided with the damper, the damper generates large resistance when rotating at a high speed, so that the safety rope 4d is tightened, the tightened safety rope 4d can pull the far end of the jaw 4b to the ratchet bar 3, the pawl 4c on the jaw 4b is matched with the ratchet bar 3, and the whole anti-falling device 4 is locked on the ratchet bar 3 thoroughly.

When a person moves up and down at a normal speed, the far end of the claw 4b is far away from the ratchet bar 3 due to the elastic force of the elastic piece 4i, and the safety rope 4d drags the anti-falling device 4 to move up and down only by overcoming the dead weight of the anti-falling device 4, at the moment, the safety rope 4d is in a loose state and is not enough to overcome the elastic force of the elastic piece 4 i.

And when the person moves upwards, the pulling force of the safety rope 4d is equal to the resistance of the damper plus the dead weight of the anti-falling device 4, even if the safety rope 4d pulls the far end of the claw 4b to the ratchet rack 3, the normal ascending of the person cannot be influenced because the ratchet rack 3 allows unidirectional movement.

When the person goes down, the tension of the safety rope 4d is equal to the resistance of the damper minus the absolute value of the self-weight of the fall protection device 4. Therefore, the tension of the safety rope 4d is far smaller than that of the person going upwards, and the safety rope 4d is not tightened enough to lock the claw 4 b.

Specifically, the distal end of the claw 4b will lift the safety rope 4d to bend the safety rope 4d, and when the safety rope 4d is in a loose state or the tension stress is not enough to overcome the elastic force of the elastic member 4i, the safety rope 4d will remain lifted and bent by the claw 4b, and at this time, the pawl 4c and the ratchet bar 3 on the claw 4b are in a disengaged state, and the safety rope 4d will not be influenced to drag the anti-falling device 4 to move. When the movement speed of the anti-falling device 4 is increased, the resistance of the damper on the guide wheel 4h is increased, the anti-falling device 4 needs to be dragged by the safety rope 4d with larger force, at this time, the tension of the safety rope 4d is increased enough to overcome the elastic force of the elastic piece 4i, the far end of the claw 4b moves towards the ratchet bar 3, and finally the pawl 4c is matched with the ratchet bar 3. Meanwhile, because the pawl 4c and the ratchet bar 3 are locked in one direction during the movement, the pawl 4c only jumps forward on the ratchet bar 3 when the anti-falling device 4 moves upwards. When the person falls down and drives the anti-falling device 4 to move downwards, the pawl 4c on the claw 4b can clamp the ratchet bar 3. Preventing the personnel from falling.

As shown in fig. 1, the outer side of the upper and lower escalators 2 is provided with an annular protective structure 2a, and a ratchet bar 3 is mounted on the protective structure 2 a.

As can be seen in fig. 2, the mounting seat 4a is provided with a T-shaped slot, and the ratchet is clamped in the slot. The back of the rack is connected with the protective structure 2a through a connecting rod 5, and the connecting rod 5 penetrates through an opening in the upper face of the T-shaped clamping groove. This allows the mounting seat 4a to slide on the ratchet bar 3 stably. Specifically, the ratchet bar 3 is actually a vertically arranged stable rod, and then the ratchet is formed on one side, or the ratchet bar 3 is fixed on the rod.

As shown in fig. 3, the jaw 4b is vertically arranged, and a hinge shaft 4e is arranged at the top of the jaw 4b for connecting with the mounting seat 4 a. The elastic member 4i is a spring, and particularly, a tension spring in the embodiment of fig. 3. The top of jack catch 4b is articulated with mount pad 4a, and the bottom of jack catch 4b has guide pulley 4h and supplies safety rope 4d to walk around, and the global of guide pulley 4h is fluted, and safety rope 4d imbeds in the recess. The bottom of the mounting seat 4a has two rollers 4g, and the two rollers 4g clamp the safety rope 4 d.

The climbing frame body 1 is a frame structure formed by connecting steel pipes through fasteners. The guard rail 6 comprises a peripheral frame and a middle net piece, and the frame of the guard rail 6 is detachably connected to the climbing frame body 1.

The guard rail 6 comprises an upper part and a lower part, the upper half part 6a is fixedly installed on the climbing frame body 1, the upper edge of the lower half part 6b is hinged to the lower edge of the upper half part 6a through a hinge 6c, and the bottom of the lower half part 6b is provided with a movable buckle which is detachably connected with the climbing frame body 1. When the material is transported on the horse way, only the lower half part 6b needs to be rotated upwards, and a feed inlet can be opened.
