Problems solved by technology

[0002] During the high-altitude construction of power transmission overhead line power towers, the safety protection of construction personnel will be involved. In the past, workers often climbed power poles and towers with bare hands, without effective safety protection measures. Unimaginable serious consequences have occurred. In the prior art, rail-type anti-drop devices are arranged respectively in the vertical direction of the power tower and the horizontal direction of the cross bar, but the effect is not ideal, and the total price of the equipment is high, and the maintenance cost is high. , many small-scale units cannot be popularized, resulting in frequent accidents of falling from power poles and towers, which makes the personal safety of construction workers not guaranteed. High-quality, low-cost power tower fall prevention system

Embodiment 1

[0025] Embodiment 1: As shown in Fig. 1, the wire rope type anti-drop system for electric power towers, the system consists of an upper support device 1, a middle limit device 2, a lower support device 3 and a steel cable 4, and the upper support device 1 includes The two parts that are fixedly connected to each other are the clamping device 11 that can be fixed on the power pole tower and the buffer 12 for fixing and connecting the cables; the clamping device 11 is composed of two "L"-shaped steel plates 111 that are superimposed The corresponding positions of the two steel plates are provided with waist holes 112, and the two steel plates are connected by bolts 113 inserted in the waist holes.

[0026] As shown in Figure 2, the middle limiting device 2 includes a clamping device 11 that can be fixed on the power pole tower and an opening card 21 that can limit the steel cable fixedly connected with the clamping device. Same as the clamping device in the upper support device....

Embodiment 2

[0032] Embodiment 2: As shown in FIG. 4, comparing the upper supporting device 1 described in FIG. 1 and Embodiment 1, the two "L"-shaped steel plates 111 on the clamping device 11 are composed of two "U"-shaped bolts 111' Instead, it is suitable to fix the upper support device 1 on the ladder where the power pole tower is a round pipe (steel pipe tower, concrete pole tower). Figure 5 As shown, the clamping device of the middle limiting device 2 is replaced by a "U"-shaped bolt and an oval steel plate that cooperates with the "U"-shaped bolt, which is suitable for fixing the middle limiting device on a power pole. Pipes (steel pipe towers, concrete pole towers) climb up the ladder. As shown in Figure 6, the fixed pressing piece 312, the movable pressing piece 314 and the fastening bolt 313 on the lower support device 3 are replaced by two "U" shaped bolts, which are suitable for fixing the lower support device 3 on the power pole tower as a round pipe ( Steel pipe tower, conc...

Abstract

The invention provides a transmission tower steel cable-typed anti-falling system, consisting of an upper supporting device, at least a middle position limit device, a lower supporting device and a steel cable; the upper supporting device comprises two parts which are fixedly connected with each other, namely a clamp device which can be fixed on the transmission tower and a bumper which is fixedly connected with the steel cable; the middle position limit device comprises a clamp device which can be fixed on the transmission tower and an open card which is fixedly connected with the clamp device and can limit the position of the steel cable; the lower supporting device comprises a clamp mechanism which can be fixedly connected with the transmission tower and a sleeve which is used for being fixedly connected with the steel cable, one end of which is fixedly connected with the lower end of the bumper while the other end thereof passes through the open cad and is fixedly connected with the sleeve; the upper part, the middle part and the lower part are fixedly clamped on the angle steel or the round steel of the transmission tower, thus being not necessary to weld or bore the transmission tower, and causing no new hidden safety trouble to the transmission tower. The system has simple structure, convenient and smart operation, is easy to be handled by operators, has high safety value, easy installation and generalization.

Description

Technical field: [0001] The invention relates to a steel cable type anti-falling system for power poles and towers, in particular to a power poles and towers steel cable type anti-falling system with low cost and high reliability, which can be applied to power transmission overhead line power poles and towers for high-altitude operations. drop system. Background technique: [0002] During the high-altitude construction of power transmission overhead line power towers, the safety protection of construction personnel will be involved. In the past, workers often climbed power poles and towers with bare hands, without effective safety protection measures. Unimaginable serious consequences have occurred. In the prior art, rail-type anti-drop devices are arranged respectively in the vertical direction of the power tower and the horizontal direction of the cross bar, but the effect is not ideal, and the total price of the equipment is high, and the maintenance cost is high. , many...
