[0039] When the working steel wire rope 2 is wound or knotted in the conduit assembly 9, if the knotted part is too large, it will be clamped between the two blocking screws 7-4 in the emergency stop control assembly 7 during movement, and then drive the trigger plate II 7-3 to move upward to trigger the trigger sensor II 7-6, after the trigger sensor II 7-6 is triggered, information is transmitted to the PLC controller, the hoist 4-1 in the lifting assembly 4 is stopped from running through the control of the PLC controller, and then the car structure 1 is stopped;

[0040] If the knotted part is not enough to drive the emergency stop control assembly 7 to move upward, the counterweight column 11 will be driven upward by the working steel wire rope 2 until it collides with the top of the emergency stop control assembly 7 during the movement of the car structure 1 (before the car structure 1 descends to the ground), and then pushes the trigger plate II 7-3 to move upward to trigger the trigger sensor II 7-6, after the trigger sensor II 7-6 is triggered, information is transmitted to the PLC controller, the hoist 4-1 in the lifting assembly 4 is stopped from running through the control of the PLC controller, and then the car structure 1 is stopped.

Since the car structure 1 is in rolling contact with the ladder assembly 8 through the plurality of roller devices, the car structure 1 can be stably lifted and moved along the guide of the ladder assembly 8, so that the workers and the maintenance devices carried by the workers are not affected by the wind, weather and other factors in the lifting and moving process, and the shaking of the car structure 1 and other equipment is avoided.

[0046] Since the other end of the working steel wire rope 2 is arranged in the guide pipe assembly 9, the guide pipe assembly 9 can guide and protect the working steel wire rope 2, so as to avoid the shaking of the working steel wire rope 2 under the influence of the wind, weather and other factors, or the entanglement and collision of the working steel wire rope 2 with other parts of the lifting system or other parts on the moving path, thereby prolonging the service life of the working steel wire rope 2.

[0047] Further referring to Figure 4In the working process, the state monitoring assembly 5, the safety steel wire rope 6 and the safety lock 10 cooperate together to monitor the lifting movement state of the car structure 1 in real time, and brake the car structure 1 when the car structure 1 falls or hits the top, thereby improving the safety of the workers, and the specific principle is as described above, which will not be repeated here.

The truss tower lifting system as described in claim 1, characterized in that: The emergency stop control assembly (7) includes a position-adjustable trigger sensor 2 (7-6) installed on the truss tower; it also includes a counterweight plate (7-1) with a through slot in the middle, the counterweight plate (7-1) passing through the top of the conduit assembly (9) and supported on the ladder assembly (8), a support cylinder mechanism being installed on the counterweight plate (7-1), the upper end of the conduit assembly (9) passing through the support cylinder mechanism and slidingly contacting it; two parallel blocking screws (7-4) being installed on the top of the support cylinder mechanism, with a gap between the two blocking screws (7-4) for a safety wire rope (6) to pass through; and a trigger plate structure being installed on the top of the support cylinder mechanism for triggering the trigger sensor 2 (7-6).

5. The truss tower lifting system as described in claim 4, characterized in that: The support cylinder mechanism includes two guide plates (7-2) that are installed together and detachably connected to the counterweight plate (7-1). The two guide plates (7-2) are detachably connected by bolts and lock nuts. The two guide plates (7-2) that are installed together form a square tube that slides with the guide assembly (9). The trigger plate structure includes two trigger plates (7-3) that are semi-circular and have their diameter edges bent downwards. The two trigger plates (7-3) are detachably connected by bolts and lock nuts. Each trigger plate (7-3) has an opening slot at its center. The two opening slots that are installed together form a rope-passing slot (7-5) through which the upper end of the support cylinder mechanism can pass. The inner edge of each opening slot is bent downwards and connected to the upper end of the corresponding guide plate (7-2) through a blocking screw (7-4) and a lock nut.

6. The truss tower lifting system as described in claim 1, characterized in that: The ladder assembly (8) includes several ladder sections (8-1) installed on the truss tower, with the ladder sections (8-1) connected end to end; the conduit assembly (9) includes rope conduit sections (9-2) installed on each ladder section (8-1) and arranged parallel to it, with an installation sleeve (9-1) for plugging and mating between two adjacent rope conduit sections (9-2), and also includes several installation pressure plates (9-3) installed on the corresponding ladder sections (8-1) and an installation adapter plate (9-4) installed through the several installation pressure plates (9-3), with a conduit bracket (9-5) installed on the installation adapter plate (9-4) for clamping and fixing the rope conduit section (9-2), and a V-shaped groove adapted to the outer peripheral wall of the rope conduit section (9-2) opened at the inner end of the conduit bracket (9-5).

7. The truss tower lifting system as described in claim 1, characterized in that: The lifting assembly (4) includes a lifting mounting frame (4-2), on which a hoist (4-1) and a conduit mounting plate (4-5) are mounted. It also includes a wire rope conduit (4-4) mounted on the conduit mounting plate (4-5). The wire rope conduit (4-4) includes an arc-shaped pipe section that is connected to the upper end of the hoist (4-1). A straight pipe section is integrally formed at the lower end of the arc-shaped pipe section. A wire rope guide sleeve (4-6) connected to the lifting mounting frame (4-2) is installed at the lower end of the straight pipe section.
