Description

A soft ladder connection structure for overhead cables

【Technical field】

The invention relates to a soft ladder, in particular to a soft ladder connection structure for overhead cables.

【Background technique】

In the installation of insulators for overhead cables, workers with short spans often use soft ladders to hang on the steel frame of the power tower and the cross arm in an arc shape, so that the construction personnel can be placed under the cross arm to facilitate the installation of insulators and others. For power accessories, due to the large gaps in the existing ladders, it is easy to step into the air during operation, which has great potential safety hazards.

【Content of invention】

In order to overcome the deficiencies in the background technology, the present invention discloses a ladder connection structure for overhead cables. The present invention adds hanging nets between cross bars so that the hanging nets can be removed or fixedly connected between two cross bars. Hanging on the steel frame of the power tower and the cross arm can avoid the phenomenon of stepping into the air.

In order to realize the described invention object, the present invention adopts following technical scheme:

A soft ladder connection structure for overhead cables, including an L-shaped hook at one end, an L-shaped hook at the other end, connecting ropes, cross bars, hanging nets and screws, and the two ends of a plurality of cross bars are fixed on two connecting ropes at intervals. The two ends of the two ends of the plurality of cross bars on the connecting rope are respectively provided with an L-shaped hook at one end and an L-shaped hook at the other end, and one side of the plurality of hanging nets is fixed on one side of the plurality of cross bars. The other side of a hanging net is provided with a steel bar, and at least two hanging ropes are arranged on the hanging net on one side of the steel bar, and the two hanging ropes are connected to adjacent cross bars by screws, that is to say, one is fixed on each cross bar. Hanging net, another adjacent cross bar connects the lanyard of described hanging net by screw.

In the ladder connection structure for overhead cables, one side of the plurality of hanging nets is fixed on one side of the plurality of cross bars through steel plates.

Owing to adopting above-mentioned technical scheme, the present invention has following beneficial effect:

The soft ladder connection structure of the overhead cable according to the present invention, the present invention adds a hanging net between the cross bar and the cross bar, so that the hanging net can be removed or fixedly connected between two cross bars, and hung on the steel frame of the power tower The upper and cross arms can avoid the phenomenon of stepping into the air; the invention has two purposes, the hanging net is taken off to form a soft ladder, and the hanging net is installed to prevent stepping into the empty working net ladder, which has the advantages of low cost and the like.

【Description of drawings】

Fig. 1 is a structural schematic diagram of the present invention.

Fig. 2 is a schematic diagram of the hanging net structure of the present invention.

In the figure: 1. L-shaped hook at one end; 2. Cross bar; 3. Connecting rope; 4. Hanging net; 5. Screw; 6. Hanging rope; 7. L-shaped hook at the other end; 8. Steel bar; 9. Steel plate.

【Detailed ways】

The present invention can be explained in detail by the following examples, and the purpose of disclosing the present invention is intended to protect all technical improvements within the scope of the present invention,

The soft ladder connection structure of the overhead cable described in conjunction with accompanying drawing 1 or 2 includes an L-shaped hook 1 at one end, an L-shaped hook 7 at the other end, a connecting rope 3, a cross bar 2, a hanging net 4 and a screw 5, and a plurality of cross bars 2 The two ends are fixed on two connecting ropes 3 at intervals, and the two ends of the crossbars 2 at the two ends of the plurality of crossbars 2 on the two connecting ropes 3 are respectively provided with an L-shaped hook 1 at one end and an L-shaped hook at the other end. 7. One side of a plurality of hanging nets 4 is fixed on one side of a plurality of cross bars 2 through a steel plate 9, and the other side of a plurality of hanging nets 4 is provided with a reinforcing bar 8, and the hanging net 4 on one side of the reinforcing bar 8 is provided with At least two lanyards 6, two lanyards 6 are connected to adjacent crossbars 2 by screws 5, that is to say, a hanging net 4 is fixed on each crossbar 2, and another adjacent crossbar 2 is connected by screws 5 Connect the lanyard 6 of the hanging net 4.

Implement the ladder connection structure of the overhead cable described in the present invention. When the present invention is used as a ladder for going up and down, one end of the L-shaped hook 1 is hung on the climbing object, and the cross bar 2 between the two connecting ropes 3 can be used to climb up. Climbing; when installing insulators and other power accessories at the lower part of the cross arm, hang the L-shaped hook 1 at one end and the L-shaped hook 7 at the other end on the steel frame of the power tower and the cross arm, and the construction personnel can stand on the hanging net 4 or The operation on the cross bar 2 can avoid the occurrence of stepping into the air.

The unspecified parts of the present invention are prior art.
