Description

Technical Field

[0001] The utility model relates to the technical field of anti - falling devices, and particularly relates to an anti - falling device for high - altitude power grid operation. Background Technique

[0002] High - altitude power grid operation refers to the operation carried out on the cables erected at high altitude through iron towers. Since the high - altitude power grid is at a relatively high distance from the ground and belongs to the operation with a high risk of falling, when construction workers operate on the high - altitude power grid, an anti - falling device usually needs to be set at the operation position to ensure the personal safety of the operators.

[0003] However, the existing anti - falling measures for high - altitude power grid operation usually connect one end of a safety rope to a single cable using a safety hook, and the other end of the safety rope is connected to a safety harness. Then, the operator wears the safety harness to operate. In this way, after the operator slips off the cable, the weight is easily concentrated entirely on the safety hook and the cable where the safety hook is located, which is likely to have an adverse impact on the tension of the single cable. In addition, since the safety hook is connected to the cable at a single point, it is prone to swing left and right, and the stability is poor; moreover, after the operator falls off the cable, it is difficult to rely on the safety rope to return to the cable. Content of the Utility Model

[0004] The purpose of the utility model is to provide an anti - falling device for high - altitude power grid operation to solve the problems raised in the above - mentioned background technique.

[0023] Such as Figures 1 to 4As shown, the anti-fall device for high-altitude power grid operation in this embodiment includes a left card plate 1 and a right card plate 6. The left card plate 1 and the right card plate 6 are of the same size and have a symmetrical structure. After being spliced ​​together, they can form a complete closed structure, which is convenient for installation and disassembly. An opening 2 is provided in the middle of the left card plate 1 and the right card plate 6. The opening 2 allows the cable on the high-altitude power grid to smoothly enter the card slot 3 or the limiting half-slot 10, thereby facilitating the connection of the anti-fall device with the cable. A card slot 3 is provided in the middle of the opening 2. The cross-section of the card slot 3 is "semicircular", which can better fit the cable with an arc outer surface, thereby increasing the stability of the connection between the anti-fall device and the cable. A friction block 9 is provided in the middle of the card slot 3. The friction block 9 can increase the fit between the card slot 3 and the cable surface and reduce the shaking of the device on the cable. A limiting half-slot 10 is provided at the top and bottom of the opening 2. The limiting half-slot 10 can form a complete semicircular groove after the left card plate 1 and the right card plate 6 are spliced, combined and fixed, which can also fit the cable. The surface makes the anti-fall device fit on multiple cables, thereby realizing the dispersion of cable force. The bottom of the front of the left card plate 1 and the right card plate 6 are fixedly connected with a pedal 4. The pedal 4 is convenient for the operator to stand and rest temporarily to replenish physical strength, thereby reducing the probability of the operator slipping off the cable. A climbing rope 5 is provided at the bottom of the left card plate 1. After being pulled by the counterweight ball 12, the climbing rope 5 always remains in a vertical downward state, thereby facilitating the operator who slips off the cable to grab and climb, which can effectively reduce the difficulty of the operator to get back on the cable. The bottom end of the climbing rope 5 is fixedly connected with a counterweight ball 12, and the counterweight ball 12 is a solid rubber ball, which plays a role in stabilizing the climbing rope 5. A connecting rope 7 is provided in the middle of the right card plate 6. The connecting rope 7 is made of steel wire and is resistant to pulling. A safety harness 8 is fixedly connected to the bottom end of the connecting rope 7. A channel 15 is opened inside the right card plate 6. The channel 15 can increase the contact area between the connecting rope 7 and the right card plate 6, thereby improving the stability of the connecting rope 7 after being connected to the right card plate 6.

[0024] Specifically, the top and bottom ends of the left clamping plate 1 and the right clamping plate 6 are fixedly connected with ear plates 11, the middle movable thread of the ear plate 11 is penetrated by a bolt 16, and the end movable thread of the bolt 16 is sleeved with a nut. The ear plate 11 can make the left clamping plate 1 and the right clamping plate 6 spliced ​​and installed on the cable of the high-altitude power grid, thereby realizing the installation of the anti-fall device on the high-altitude power grid.

[0025] Furthermore, the left card plate 1 and the right card plate 6 are fixedly connected by ear plates 11 and bolts 16, and the left card plate 1 and the right card plate 6 are connected to the cable movable sleeve on the high-altitude power grid through the opening 2 and the slot 3. The left card plate 1 and the right card plate 6 can be used normally during the high-altitude power grid operation only after being spliced ​​and combined. At the same time, the disassembled left card plate 1 and the right card plate 6 are convenient for storage and carrying.

[0026] Furthermore, one end of the friction block 9 is fixedly connected with a movable block 13, and one side wall of the movable block 13 is fixedly connected with a spring rod 14. The friction block 9 can increase the friction between the clamping groove 3 and the cable, making the anti-falling device not easily slide accidentally along the cable and increasing the stability of the device on the high-altitude power grid.

[0027] Furthermore, the spring rod 14 is movably embedded and connected with the clamping groove 3, and the friction block 9 is movably embedded and connected with the clamping groove 3 through the spring rod 14. The spring rod 14 can make the friction block 9 tightly adhere to the surface of the cable through its own deformation, thus facilitating the contact between the friction block 9 and the cable.

[0028] Furthermore, the top end of the connecting rope 7 is fixedly connected with the top inside the channel 15. A through hole is opened at the junction of the channel 15 and the right clamping plate 6. The connecting rope 7 passes through the through hole and is connected through the right clamping plate 6. The connecting rope 7 in the channel 15 can change the connection between the connecting rope 7 and the right clamping plate 6 from point connection to surface connection, thus increasing the stability of the connection between the connecting rope 7 and the right clamping plate 6.

[0029] Furthermore, the safety harness 8 is fixedly connected with the right clamping plate 6 through the connecting rope 7, and the climbing rope 5 is fixedly connected with the left clamping plate 1. The outer surface of the climbing rope 5 is rough, which is conducive to the operator to grasp and climb, thus reducing the difficulty for the operator who has slipped off the cable to get back onto the cable.

[0030] The usage method of this embodiment is as follows: When using the anti-falling device for high-altitude power grid operation, it is necessary to first put the left clamping plate 1 and the right clamping plate 6 respectively on the cable of the high-altitude power grid through the opening 2, so that the cables enter the corresponding clamping grooves 3 or the limit half grooves 10 respectively. Then, pass the bolt 16 through the ear plate 11 and lock it with a nut, so that the left clamping plate 1 and the right clamping plate 6 are assembled and fixed. At the same time, the cable embedded in the clamping groove 3 will be tightly adhered by the friction block 9, so that the left clamping plate 1 and the right clamping plate 6 are stably sleeved on multiple cables. Then, the operator can wear the safety harness 8, and then can start high-altitude operation. When the operator accidentally slips off the cable, the safety harness 8 that falls with the operator will straighten the connecting rope 7, making the connecting rope 7 in the channel 15 tense. The tension received by the connecting rope 7 will be dispersed on multiple cables through the right clamping plate 6 and the left clamping plate 1, making the amplitude of the operator's left and right swing smaller after slipping off the cable. At the same time, the operator who has slipped off the cable can grasp the climbing rope 5 straightened by the counterweight ball 12, and then get back onto the cable through the climbing rope 5. And when feeling physically exhausted, the operator can temporarily stand on the pedal 4 to rest to replenish physical strength, and can continue to carry out the operation after the physical strength is restored.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
