Description

Technical Field

[0001] The invention relates to the technical field of protective equipment attachments, and in particular to a high-altitude cable maintenance safety protection device. Background Art

[0002] Due to their special geographical location and functional characteristics, high-altitude cables face a variety of potential risks. Extreme weather conditions such as strong winds, lightning, and hail may cause damage to the cables. Therefore, in order to ensure the stability and safety of power supply and the personal safety of maintenance personnel, it is very necessary to take effective protective measures. As a part of this, the lifeline system plays a key role in ensuring the safety of personnel. The lifeline system is a safety device used for high-altitude operations. It consists of a series of components, including but not limited to anchor points, connectors, ropes, etc. These components work together to provide workers with a safe path for movement, so that even if they accidentally fall while working at heights, they can be effectively prevented, thereby avoiding or reducing injuries. The most common high-altitude fall protection equipment currently available is the vertical hook. The vertical hook is a device used for vertical protection of high-altitude cable detection in daily life. It has been widely used in the field of cable detection;

[0003] When using the existing vertical hook, first use the appropriate tools to firmly install the fixed anchor point to the structure according to the selected position. Make sure the anchor point is installed correctly and can withstand the expected load, and install the pulley to the positioning rope to ensure that it can slide smoothly along the rope. The pulley should be connected to the safety belt to provide additional support and stability when the worker moves up and down; it is found in the use of the existing vertical hook that most of the existing hooks are artificially suspended, resulting in a low safety factor during the suspension process, and there is a risk of falling from a height, thus resulting in low work efficiency.

DETAILED DESCRIPTION

[0026] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0027] Embodiment: A high-altitude cable maintenance safety protection device of the present invention also includes:

[0028] S1: During the process of power workers conducting power maintenance, it is necessary to create a vertical lifeline system for power workers, which is set vertically from top to bottom and is usually used for safety protection when climbing structures or entering confined spaces. In this process, the driving device is started to lift and lower, so that it drives the clamping device to open, and the lifting mechanism is rotated and placed horizontally, so that it can be lifted by horizontal placement and the bottom hook of the drone, driving the equipment to be lifted and placed at a high place where the wire is detected;

[0029] S2: After the equipment is transported to the designated location, the contact point on the front drive device is contacted with the placement area to change its position. After driving the infrared sensor to change its position, the signal is transmitted to the main control box powered by the power box. The single-chip microcomputer and signal transmitter in the main control box transmit instructions to drive the drive device to run in the reverse direction, so that the hoisting mechanism rotates and rises, and cooperates with the clamping device to align and fix it, so that it is set with the fixed place;

[0030] S3: After the equipment is assembled, the top is supported by the top adjustment device, and the bottom is adjusted by the fixing device. The motor drive on the bottom adjustment device drives the equipment to gradually shrink the clamping point to fix the clamping position. This allows the equipment to adapt to most maintenance positions, improving the universality and automation level of the equipment.

[0031] As a preferred embodiment of the above, a high-altitude cable maintenance safety protection device of the present invention, the driving device also includes:

[0032] S1: When the device is hoisted by a drone, the bottom touch panel is driven to contact the placement area, and the bottom touch panel is stably raised and lowered with the help of magnetic attraction. After the bottom touch panel is displaced, the infrared sensor activates the electric push rod to raise and lower according to the change in position. When the electric push rod slides on the connecting sleeve, the position of the tripod is driven to change.

[0033] S2: The tripod is placed on the connecting sleeve on both sides. The length of the fixed ring can be compensated for the difference in the lifting position of the fixed ring by rotating the tripod, so that the fixed ring can be lifted and lowered stably;

[0034] S3: Under the action of the electric push rod, the fixed ring is pushed and pulled, so that it drives the telescopic rod connected to it to slide in the installation sleeve, driving the equipment to be clamped and hoisted.

[0035] As a preferred embodiment of the above, a high-altitude cable maintenance safety protection device of the present invention, the hoisting method also includes:

[0036] S1: When the equipment is hoisted, the telescopic rod is lifted up, driving the rack connected to it to rise accordingly;

[0037] S2: Since the gear is installed on the limit plate, the limit plates are evenly distributed on both sides of the mounting sleeve. Through the meshing relationship between the gear and the rack, the limit plates on both sides are driven to rotate in the same direction, so that it can be hoisted with the drone;

[0038] S3: During this process, the limit rod passes through the drone and is reset by the coil spring to improve the clamping stability of the equipment.

[0039] As a preferred embodiment of the above, a high-altitude cable maintenance safety protection device of the present invention, the clamping method also includes:

[0040] S1: When the electric push rod drives the tripod to rise and fall, the tripod is pulled by the spherical rod, so that the clamping device and the hoisting mechanism perform different movements. The clamping device clamps the hoisting mechanism to contract, the hoisting mechanism is unfolded, and the clamping device is opened. The spherical rod is connected with the tripod and the support arm to rotate accordingly. In this process, the clamping arm connected with the support arm is dropped and fixed accordingly, and the fixed location is set.

[0041] S2: During this process, slide the buckle to make it slide and adjust on the clamping arm, adjust the approximate size of the bottom adjustment device, and fix it by turning the knob;

[0042] S3: After the buckles are matched, the buckles are fixed by inserting the limit card on the two sets of buckles, and the rope loop is inserted into the ring to build the lifeline system.

[0043] As a preferred embodiment of the above, a high-altitude cable maintenance safety protection device of the present invention, the adjustment method also includes:

[0044] S1: After the buckles are engaged, the motor is started to drive the screw connected to it to rotate, and the rotation of the screw drives the sliders on the two sets of buckles to slide accordingly, and the sliding of the slider pulls or pushes the cross rods, so as to change the cross angle between the corresponding two sets of cross rods and tighten them in a scissor-like manner;

[0045] S2: During this process, the positioning block is adjusted in the slot as the cross bar rotates, and the positioning plate of the cross bar rotates to perform positioning clamping;

[0046] S3: During this process, the top portion drives the arc rod to rotate through the rotation of the support arm, and the top portion is supported by the push block and the second spring adjustment.

[0048] The “first”, “second” and “third” in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0049] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
