Both ends of the steel wire rope 2 are fixedly connected to the steel structure framework 1 inside the roof of the construction site. The two steel wire ropes 2 are respectively connected to the working platform 3 through the first sliding connection mechanism. The left and right ends of the working platform 3 are respectively provided with traveling mechanisms. The traveling mechanism includes a pallet 4 and a sliding plate 7 that are slidably connected to each other. The pallet 4 is fixedly connected to the left or right end of the working platform 3.

Both ends of the sliding plate 7 are connected to the steel wire rope 2 through the second sliding connection mechanism.

The steel wire rope 2 is sleeved inside the first sliding sleeve 9.

[0027] In a further embodiment, as Figures 1-4 shown, connecting plates 73 are respectively connected between the front ends and the rear ends of the two sliding plates 7. Second hydraulic cylinders 13 arranged side by side with the first hydraulic cylinders 14 on the same side are respectively provided at the top ends of the left and right sides of the two connecting plates 73. The second sliding connection mechanism includes a second sliding sleeve 11 connected to the telescopic end of the second hydraulic cylinder 13. The steel wire rope 2 is sleeved inside the second sliding sleeve 11. The fixed end of the second hydraulic cylinder 13 is connected to the connecting plate 73 through the second tension sensor 15.

[0028] In a further embodiment, as Figures 1-4 shown, the first sliding sleeve 9 and the second sliding sleeve 11 are respectively configured with steel wire rope locking structures.

[0029] In a further embodiment, as Figures 1-4 shown, the steel wire rope locking structure includes electric push rods (the first electric push rod 10, the second electric push rod 12). The fixed end of the electric push rod is embedded in the top of the first sliding sleeve 9 or the second sliding sleeve 11, and the telescopic end penetrates through the first sliding sleeve 9 or the second sliding sleeve 11 and is fixedly connected with an arc-shaped wear-resistant pressing plate 18.

[0030] In a further embodiment, as Figures 1-4 shown, the arc-shaped wear-resistant pressing plate 18 is made of nitrile rubber material.

[0031] In a further embodiment, as Figures 1-4As shown, on the left and right sides at the bottom end of the pallet 4, linear chutes (a common structure, not shown in the figure) are provided in parallel. On the left and right sides at the upper end of the sliding plate 7, linear slide rails 72 that are slidably connected to the linear chutes are provided (as Figure 4 shown, which can ensure the sliding connection and prevent them from disengaging from each other). On the upper surface of the sliding plate 7 between the two linear slide rails 72, a rack structure 71 is provided.

[0032] In a further embodiment, as Figures 1-4 shown, the driving mechanism includes a motor 6 and a gear 5. A through notch 8 is provided on the pallet 4. The lower end of the gear 5 passes through the notch 8 and is meshed and connected to the rack structure 71. The motor 6 is fixedly provided at the upper end of the pallet 4, and the output shaft of the motor 6 is fixedly connected to the gear 5.

[0033] In a further embodiment, as Figures 1-4 shown, a hydraulic station that is oil-way connected to the first hydraulic cylinder 14 and the second hydraulic cylinder 13, a power supply that is electrically connected to the electric push rod and the motor 6 respectively, a control panel for controlling the actions of the first hydraulic cylinder 14, the second hydraulic cylinder 13, the electric push rod and the motor, and a display that is electrically connected to the first tension sensor 16 and the second tension sensor 15 are provided inside the operation platform 3.

[0034] In a further embodiment, as Figure 2 shown, a safety rope 17 is also connected between the connecting plate and the second sliding sleeve and between the operation platform and the first sliding sleeve.

[0035] The working principle of this new type:

[0036] As Figure 1 , 2As shown in the figure, when the working platform needs to move along the steel wire rope, the first hydraulic cylinder contracts, and the second hydraulic cylinder does not apply pulling or pressing force. When the load value of the first tension sensor is consistent with the load of the working platform itself, the motor is started, and the slide plate is moved forward or backward through the transmission of the gear and the rack; when the slide plate moves to a certain position, the second hydraulic cylinder contracts, and the first hydraulic cylinder is depressurized. When the load value of the second tension sensor is consistent with the load value of the working platform itself, the motor is started to make the working platform move forward or backward along the steel wire rope and the rack structure. At this time, the slide plate is stationary relative to the steel wire rope. In the above process, when the electric push rod extends, it can assist the first sliding sleeve or the second sliding sleeve to lock with the steel wire rope to prevent the working platform or the slide plate from moving relative to the steel wire rope. When the first sliding sleeve or the second sliding sleeve locks with the steel wire rope, the motor can rely on the transmission of the gear and the rack structure to move the slide plate or the working platform. Since the first sliding sleeve or the second sliding sleeve does not apply a pulling force to the steel wire rope when moving, and the electric push rod drives the arc-shaped wear-resistant pressure plate to retract, the relative friction between the first sliding sleeve or the second sliding sleeve and the steel wire rope is very small, and there will be no severe wear. At the same time, the movement process is easy and labor-saving, which can ensure construction safety and improve construction efficiency. Through the above settings, the present invention enables the working platform to move along the steel wire rope in a manner similar to a robot crawling, solving the problem that the working platform has difficulty moving on the steel wire rope in the prior art. At the same time, by connecting the two steel wire ropes with the steel structure framework, the stability of the working platform is ensured, so that the construction efficiency can be significantly improved on the basis of ensuring construction safety.
