Abstract

An anti-falling ring. The anti-falling device mainly solves the problems of high investment, complex operation and inflexible use of the conventional anti-falling device for the operation of the power transmission tower. The method is characterized in that: the main part (10) is L-shaped, one end of the L-shaped is provided with a hook (104), the upper part of the other end is connected with a hanging ring (101), the hanging ring (101) faces to one side of the main part and is opened, and the rear side face of the main part of the hanging ring (101) is connected with a locking plate (103) through a pin shaft. The anti-falling ring is low in cost, can be repeatedly used and is flexible and convenient to operate.

Description

Anti-falling ring

Technical Field

The invention relates to the field of electric power, in particular to an anti-falling ring for operation of an iron tower of a power transmission line.

Background

At present, domestic power transmission line construction or maintenance work, the tower climbing operation personnel mostly adopt the mode of bare-handed climbing to climb up and down the iron tower, lack effective safety protection measures, and when the physical strength of the operation personnel descends or the misoperation is once lost or stepped on the slip, serious casualty accidents can occur. In recent years, rail type anti-falling devices are installed in some areas, although the rail type anti-falling devices can play a certain protection role, each iron tower needs to be provided with one rail type anti-falling device, so that the rail type anti-falling device is large in investment, high in maintenance cost, complex in operation, inflexible in use and influenced by external factors such as corrosion deformation, and therefore the rail type anti-falling device is low in practicability and not widely applied.

Disclosure of Invention

In order to overcome the defects of large investment, complex operation and inflexible use of the conventional anti-falling device for the operation of the power transmission tower, the invention provides the anti-falling ring which has low cost, can be repeatedly used and is flexible and convenient to operate.

The technical scheme of the invention is as follows: the utility model provides an anti-falling ring, includes the main part, the main part is L shape, and the one end of L shape is equipped with the couple, and other end upper portion is connected with the link, the link is in the face of one side opening of main part, and the main part trailing flank of link has the locking plate through round pin hub connection.

The locking plate is in a hook shape, and the bottom edge of the upper half part of the hook is flush with the bottom surface of the L-shaped upper half part of the main body.

The inner surface of the upper half part of the main body is embedded with a strong magnetic sheet.

The invention has the following beneficial effects: by adopting the scheme, the anti-falling ring is low in manufacturing cost, convenient to carry and store and reusable; any fixing equipment does not need to be installed on the iron tower, the structure of the iron tower is not changed, and the operation is flexible and convenient; the anti-falling rings of various types are processed, so that the problem of safe anti-falling of iron towers of all specifications can be solved, and the application range is wide.

fig. 3 is a plan view of the present invention.

In the figure, 10-a main body, 101-a hanging ring, 102-a strong magnetic sheet, 103-a locking sheet and 104-a hook.

Detailed Description

The invention will be further described with reference to the accompanying drawings in which:

shown by fig. 1 to 3, a prevent weighing down ring, includes main part 10, main part 10 is L shape, and the one end of L shape is equipped with couple 104, and other end upper portion is connected with link 101, link 101 right side is the one side opening of main part promptly, and the main part trailing flank of link 101 has locking plate 103 through round pin hub connection, locking plate 103 is the crotch shape, and the end of crotch first part is along the bottom surface parallel and level with main part 10L shape first part. The hook 104 and the hook on the locking plate 103 can be clamped on the angle iron, so that the anti-falling ring main body 10 is hung on the angle iron. When the anti-falling ring is hung on the angle iron, the locking plate 103 cannot be loosened and is firmly clamped under the condition of no external force. The hook can be separated from the angle iron only by manually lifting the lower end of the locking plate 103, and the anti-falling ring can be taken down from the angle iron. The main body 10 can be made into different types according to the size of angle iron on an iron tower, so that the anti-falling ring can be suitable for iron towers with different specifications. The inner surface of the upper part of the main body 10 is embedded with the strong magnetic sheet 102, and the anti-falling ring can be adsorbed on the angle iron by the strong magnetic sheet 102, so that the anti-falling ring is prevented from sliding off the inclined angle iron.

The anti-falling ring is matched with a ground device for use, when an operator climbs an iron tower, the corresponding anti-falling ring is selected according to the size of angle iron on the iron tower, and then a plurality of anti-falling rings are carried according to the height required to climb. In the climbing process, an anti-falling ring is hung on the angle iron every 3 meters according to the position of the angle iron of the iron tower, and then the safety rope is wound around the hanging ring 101. In case that the operator falls carelessly in the climbing or operation process, the anti-falling ring is used as a hanging point, the safety rope is clamped by combining the locking of the ground device, the operator is hung in the air through the safety rope, and the safety of the operator is reliably ensured.
