[0007] A fall prevention device capable of being pre-suspended for high-altitude operations comprises a hook device, wherein an anti-fall rope is arranged at the lower end of the hook device, an anti-fall self-locking device is slidably arranged on the outer surface of the anti-fall rope, and an insulating telescopic rod is arranged on one side of the hook device.
[0008] Preferably, the hook device comprises a hook body and an anti-hooking device, and the anti-hooking device is arranged on one side of the lower end of the hook body.
[0009] Preferably, a remote pull-wire unlocking device is provided at the lower end of the hook body.
[0010] Preferably, a first mounting hole is opened on one side of the hook body, and the insulating telescopic rod is fixedly connected to the one side of the hook body through the mounting hole.
[0011] Preferably, a second mounting hole is opened at the lower end of the hook body, and the anti-fall rope is fixedly connected to the lower end of the hook body through the second mounting hole.
[0012] Preferably, a fixing belt is fixedly connected to one side of the anti-falling self-locking device.
[0013] In the above technical solution, the technical effects and advantages provided by the utility model are:
[0014] 1. The utility model, through the anti-fall device, can enable workers to work at heights on structures such as transmission towers without ladders, foot nails, etc. without losing anti-fall protection during the climbing process, and it is convenient to fix the anti-fall device, which greatly improves the safety and efficiency of high-altitude operations.
[0015] 2. The utility model can hang the hook to a fixed point 8-9 meters above the ground through a telescopic pull rod, thereby avoiding the lack of anti-fall protection when people climb and hang the hook for the first time, and effectively reducing labor costs and falling risks.
[0016] 3. The utility model can operate the anti-unhooking device of the hook on the ground to unlock it through the remote pull-wire unlocking device, thereby avoiding the situation where the person lacks anti-fall protection when the last climb is performed when unlocking the unhooking device, and effectively reducing the labor cost and the risk of falling.

[0025] The anti-fall device 4 can slide on the anti-fall rope 3 at a normal climbing speed. When the worker falls rapidly, the anti-fall device 4 can self-lock to prevent the worker from falling.
[0026] To facilitate unlocking the hook, Figure 1-2 As shown, the hook device 1 includes a hook body 6 and an anti-unhooking device 7. The anti-unhooking device 7 is arranged on one side of the lower end of the hook body 6. The lower end of the hook body 6 is provided with a remote pull-wire unlocking device 2.
[0027] The remote pull-wire unlocking device 2 can achieve the anti-unhooking effect and remotely unlock the anti-unhooking device 7 by pulling the wire. After completing the high-altitude work, the personnel return to the ground and use the tail end of the pull wire of the remote pull-wire unlocking device 2 to unlock the anti-unhooking hook of the hook.
[0028] In order to prevent the hook body 6 from being supported, Figure 1-2 As shown, a first mounting hole is opened on one side of the hook body 6, and the insulating telescopic rod 5 is fixedly connected to one side of the hook body 6 through the mounting hole.
[0029] The insulating telescopic rod 5 has insulating properties and can be extended to 8-9 meters, so as to hang the hook body 6 to a fixed point at a predetermined height, thereby meeting the structural strength and weight requirements.
[0030] In order to facilitate the installation of the anti-fall rope 3, Figure 1 As shown, a second mounting hole is opened at the lower end of the hook body 6, and the anti-fall rope 3 is fixedly connected to the lower end of the hook body 6 through the second mounting hole.
[0031] The anti-fall rope 3 can be conveniently fixed through the second mounting hole, and then the tail end of the anti-fall rope 3 is fixed to a fixed point on the ground to stretch it and adjust its length to avoid entanglement.
[0032] Finally, for convenience, the anti-fall self-locking device 4 is fixed on the safety belt, such as Figure 1-2 As shown, a fixing belt 8 is fixedly connected to one side of the anti-falling self-locking device 4 .
