(1) the length of the cable-stayed structure is adjusted, the cable-stayed structure can adopt a steel wire rope, and the length of the cable-stayed structure is adjusted by pulling the steel wire rope to shorten the length of the steel wire rope between the safety channel and the integrated climbing frame; when the above-described escape route is used, the turnbuckle 11 may be rotated to adjust the length of the diagonal member 10. No matter which mode is adopted, after the length of the diagonal draw bar structure is adjusted, the safe channel inclines upwards, and one end of the safe channel connected with the tower crane is separated. It should be noted that if the end of the safety channel connected with the tower crane is not lapped but detachably connected by the fastening device, the fastening device needs to be firstly detached, and if the hook 1 is arranged, the length of the safety channel can be firstly extended according to needs, so that the hook 1 is firstly detached from the connection.
(2) After the safety channel is inclined upwards for a certain angle, whether the length of the safety channel is contracted or not is selected according to whether a barrier exists in the upper moving space, when the safety channel is contracted, the bolt 5 connected with the safety channel can be detached firstly, then the length of the safety channel is contracted, and after the safety channel is contracted to a specified length, the bolt 5 is installed. It should be noted that, if the position limiting structure is arranged between the telescopic part and the main body part on the safe passage, the bolt 5 may not be installed at this time, and the position of the telescopic part is limited by the position limiting structure to move, so as to ensure the safety and stability of the safe passage when the safe passage climbs along with the integrated climbing frame.
(3) After fixing the relative position of pars contractilis and main part, promote integrated height of climbing the frame, at this moment, because the escape way articulates on integrated climbing the frame, at integrated in-process that climbs the frame promotion, the escape way promotes thereupon together, relies on the articulated shaft and draws the structure to realize fixing and fix to the escape way to one side at the in-process of whole promotion.
(4) After reaching the designated height, the bolt 5 installed before is detached (if installed), then the safety channel is extended and fixed, so that the length of the safety channel can be larger than the distance between the tower crane and the integrated climbing frame.
(5) Adjusting the length of the cable-stayed structure, in this case, should be elongating the length of the cable-stayed structure, i.e. adjusting in reverse with respect to step (1), thereby releasing the secure channel downwards. It should be noted that the length of the cable-stayed structure can be reasonably adjusted according to whether the safety channel is in contact with the cross rod or not, so that better contact connection is ensured.
(6) After the horizontal pole of escape way overlap joint on the tower crane, realize the overlap joint of escape way and tower crane, if there is couple 1, then adjust escape way at length direction as required for couple 1 can be effectively connected with the horizontal pole, if there is fastener, then installed fastener, finally make escape way reconnect on the tower crane. And can climb the length of the interval between the frame according to tower crane and integration and suitably adjust the escape way, guarantee that the escape way is stably connected between tower crane and integration and climb the frame.
(7) And (5) repeating the steps (1) to (6) when climbing up again is needed.
The safety passageway shortens the back and all can adopt safety locking device to lock behind the extension, and safety locking device can be for structures such as bolt, stopper for inject the removal of length direction of pars contractilis on the main part, guarantee after sliding to target in place, the firm in connection, reliable of main part and pars contractilis of safety passageway, guarantee the current safety of personnel.
The principle and the implementation mode of the invention are explained by applying a specific example, and the description of the embodiment is only used for helping to understand the method and the core idea of the invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, the specific embodiments and the application range may be changed.
