[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Please see Figure 1-4 This utility model provides a new technical solution: a safety protection device for high-altitude power construction, including a support base plate 1, three movable wheels 3 fixedly installed on the lower surface of the support base plate 1, and a protection component. The protection component is set on the support base plate 1 and includes two multi-segment auxiliary telescopic rods 4. The telescopic ends of the two multi-segment auxiliary telescopic rods 4 are fixedly connected to a connecting plate 7.
[0031] Among them, the two connecting plates 7 are fixedly connected to the opposite surfaces of the moving rod 19, the lower surface of the moving rod 19 is provided with a through hole 18, the inner wall of the through hole 18 is provided with an internal thread, and the inner wall of the through hole 18 is threaded with a threaded rod 2 through the internal thread.
[0032] Among them, the lower end of the threaded rod 2 rotates through the lower surface of the support base plate 1, and L-shaped fixing plates 8 are fixedly connected to both the left and right sides of the moving rod 19.
[0033] Among them, the two L-shaped fixing plates 8 are rotatably connected to the opposite surfaces of the connecting rod 9, and the outer wall of the connecting rod 9 is fixedly sleeved with the mounting wheel 10.
[0034] Furthermore, L-shaped mounting rods 11 are fixedly connected to the front and rear surfaces of the two L-shaped fixing plates 8, and auxiliary wheels 12 are provided on the front and rear surfaces of the mounting wheels 10. The two auxiliary wheels 12 are rotatably connected to the corresponding L-shaped mounting rods 11.
[0035] Furthermore, two support plates 5 are fixedly connected to the upper surface of the support base plate 1, and both support plates 5 are located on the rear side of the moving rod 19;
[0036] Among them, the opposing surfaces of the two support plates 5 are rotatably connected to a wire winding roller 17, and a wire rope 13 is fixedly installed on the wire winding roller 17.
[0037] Furthermore, the front end of the wire rope 13 passes through the upper surface of the rear auxiliary wheel 12 and through the mounting wheel 10 and the upper surface of the front auxiliary wheel 12. The lower surface of the wire rope 13 is in contact with the surfaces of the two auxiliary wheels 12 and the mounting wheel 10.
[0038] Furthermore, a hook mounting piece 14 is fixedly connected to the lower end of the wire rope 13. The hook mounting piece 14 is used to connect with the hook on the worker's safety belt.
[0039] Furthermore, the right side of the wire take-up roller 17 rotates through the outer surface of the right support plate 5. A servo motor 16 is fixedly installed on the right side of the right support plate 5, and the output end of the servo motor 16 is fixedly connected to the wire take-up roller 17.
[0040] Furthermore, a drive motor mounting box 15 is fixedly connected to the lower surface of the support base plate 1, and a servo motor is fixedly installed inside the drive motor mounting box 15.
[0041] The output end of the servo motor rotates through the upper surface of the drive motor mounting box 15, and the output end of the servo motor is fixedly connected to the lower end of the threaded rod 2.
[0042] Furthermore, when using this power high-altitude construction safety protection device, when workers need to climb to the utility pole for maintenance work, they first use the moving wheels 3 to move the support base plate 1 to the designated position;
[0043] Subsequently, when the staff climbed the utility pole, they were wearing protective clothing with hooks attached. The hooks were connected to the hook installation piece 14.
[0044] The servo motor 16 on the right side of the wire take-up roller 17 is activated. The output of the servo motor 16 drives the wire take-up roller 17 to rotate, synchronously winding or releasing the wire rope 13 according to the speed at which the worker climbs: when the worker is climbing upwards, the servo motor 16 rotates in the forward direction to release the wire rope 13. The wire rope 13 is guided by the mounting wheel 10 and the auxiliary wheel 12, and always maintains a constant vertical distance from the worker; when the worker stops climbing, the servo motor 16 stops rotating, and the wire rope 13 is taut to form a protective barrier to prevent the worker from falling accidentally.
[0045] The servo motor inside the drive motor mounting box 15 is started, and the output end of the servo motor drives the threaded rod 2 to rotate. Since the threaded rod 2 is threadedly connected to the through hole 18 of the moving rod 19, the rotation of the threaded rod 2 is converted into axial movement, which pushes the moving rod 19 to move upward. The moving rod 19 drives the connecting plate 7 to rise through the multi-section auxiliary telescopic rod 4, so that the height of the mounting wheel 10 is adjusted synchronously with the climbing height of the workers, ensuring that the wire rope 13 is always in a taut state and avoiding the wire rope from slack due to the height difference.
[0046] Among them, the wire rope 13 passes through the rear auxiliary wheel 12, the mounting wheel 10 and the front auxiliary wheel 12 in sequence to form a three-section guide structure: the mounting wheel 10 moves up and down with the moving rod 19, and the auxiliary wheel 12 is fixed on the L-shaped fixed plate 8 by the L-shaped mounting rod 11 to limit the left and right deviation of the wire rope 13, ensure that the wire rope 13 is stably guided in three-dimensional space, and reduce friction loss;
[0047] Among them, the multi-section auxiliary telescopic pole 4 adopts a hydraulic or electric telescopic structure, which can quickly adjust the height of the connecting plate 7 according to the height of the utility pole, and adapt to different specifications of utility poles; when the moving pole 19 rises, the multi-section auxiliary telescopic pole 4 extends synchronously.
[0048] Two of the three movable wheels 3 are equipped with brake devices, which can prevent the device from shifting after locking; the rigid connection between the L-shaped fixing plate 8 and the movable rod 19, together with the rotating structure of the connecting rod 9, enables the mounting wheel 10 to maintain flexibility while having the strength to withstand huge tensile forces.
[0049] When the system detects a sudden increase in tension in the wire rope 13 (such as a person falling), the servo motor 16 immediately initiates an emergency braking procedure, locking the wire take-up roller 17 via an electromagnetic brake. The buffer structure of the wire rope 13 can reduce the impact force to a safe range, dropping the worker into the air and preventing injury, thus improving the installation safety for workers working at heights.
