Embodiment 1

[0026] Such as Figure 1 to Figure 3 As shown, it is the first embodiment of the high-altitude fall prevention track of the present invention. The high-altitude fall prevention track of this embodiment includes a track body made of aluminum alloy profile 1. The extended steel wire hole 3 is used to set the steel wire 2. The steel wire 2 is set in the steel wire hole 3. The steel wire 2 and the aluminum alloy profile 1 are closely combined. Profile 1, so that the aluminum alloy profile 1 is tightly wrapped on the outside of the steel wire 2, the steel wire 2 and the aluminum alloy profile 1 are tightly combined, and the steel wire 2 cannot escape from the aluminum alloy profile 1.

[0027] see image 3 , in this embodiment, two steel wires 2 are compounded in the aluminum alloy profile 1, and the cross section of the aluminum alloy profile 1 is roughly in the shape of an "8", including two circular parts and a connecting part connecting the two circular parts, Each circular p...

Embodiment 2

[0031] Such as Figure 4 As shown, it is the second embodiment of the high-altitude fall prevention track of the present invention. In this embodiment, the cross section of the aluminum alloy profile 1 is "L-shaped", and the aluminum alloy profile 1 is compounded with three steel wires 2, as shown in the figure As shown, the upper end of the vertical part of the "L"-shaped section, the right end of the horizontal part, and the intersection of the vertical part and the horizontal part are respectively provided with steel wire holes, and a steel wire 2 is compounded in each steel wire hole. The composite structure of the aluminum alloy profile 1 and the steel wire 2 in this implementation is the same as that of the first embodiment, and will not be repeated here.

Embodiment 3

[0033] Such as Figure 5 As shown, it is the third embodiment of the high-altitude fall prevention track of the present invention. In this embodiment, the cross section of the aluminum alloy profile 1 is "I" shape, and two steel wires 2 are compounded in the aluminum alloy profile 1, such as As shown in the figure, steel wire holes are respectively provided at the junction of the vertical part of the "I" shape and the two horizontal parts, and a steel wire 2 is compounded in each steel wire hole. In this implementation, the aluminum alloy profile 1 and the steel wire 2 are combined The structure is the same as that of the first embodiment, and will not be repeated here.

Abstract

The invention relates to a high-altitude falling prevention track and a manufacturing method of the high-altitude falling prevention track. The high-altitude falling prevention track comprises a track body made of an aluminum alloy section, wherein a steel wire hole extending along the aluminum alloy section extending direction and being used for placing a steel wire is formed in the aluminum alloy section; and the high-altitude falling prevention track also comprises the steel wire arranged in the steel wire hole, and the steel wire and the aluminum alloy section are tightly compounded. The manufacturing method of the high-altitude falling prevention track comprises the following steps of: S1, threading the steel wire into the steel wire hole; and S2, extruding the aluminum alloy section to enable the steel wire and the aluminum alloy section to be tightly compounded. The high-altitude falling prevention track provided by the invention overcomes the defects of the traditional steel track and aluminum alloy track through compounding the steel wire inside the aluminum alloy section and has the advantages of light weight, high tensile strength and stiffness, capability of realizing industrial standard machining and zero loss of installation and construction materials, high universality, convenience in installation and high efficiency.

Description

technical field [0001] The invention relates to high-altitude safety protection equipment, and more specifically relates to a high-altitude fall prevention track and a manufacturing method thereof. Background technique [0002] In industries such as telecommunications, petroleum, chemical industry, and power transmission and transformation of power systems, high-altitude operations are involved. In order to ensure the safety of workers, reliable safety protection devices against falling must be provided. In high-altitude operations, rails are usually set on the tower, and the operator clamps the anti-fall device on the rail. When the high-altitude worker accidentally falls, the anti-fall device will automatically lock on the rail, thus ensuring the safety of the high-altitude worker. safety. The existing high-altitude fall prevention rails are mainly made of steel or aluminum alloy. The steel rail has a large seal, heavy weight, is difficult to transport and install, and ha...
