Abstract

The invention relates to a safety insulating net structure of a highway. The structure mainly comprises a safety insulating net, a steel wire rope, a main rope at the edge of the net and a spanning frame, wherein the safety insulating net and the steel wire rope are connected with the spanning frame. The structure is characterized in that shackles are arranged between the main rope at the edge of the net and the steel wire rope at regular intervals. When the safety insulating net is pulled over the highway in the air, people can synchronously process on the spanning frame, which can avoid the condition of net winding; a large quantity of workloads can be carried out under the condition of normal traffic of the highway, thereby the road closure time of the highway is greatly shortened; meanwhile, ascending operating personnel required by pulling the net can be reduced to 4 from 6 in the past, thus the labor power is saved; and because the road closure time is shortened, the structure provides reliable guarantee for the safe and normal traffic of vehicles on the highway.

Description

The safe insulation web frame of speedway

Technical field

The present invention relates to a kind of safe insulation web frame of speedway, specifically the safe insulation host need in the power transmission and distribution overhead wire erection process will be applied to the acrossing highway construction operation.

Background technology

In order to guarantee to guarantee that when aerial condutor is crossed speedway the safety of speedway is normally current, so respectively set up one of crossing frame in advance in the speedway both sides, draw a reliable safe insulation net of intensity on the top of two crossing frames, guarantee that aerial condutor is not sagging in passing through the process of speedway, the vehicle of speedway can be normally current safely.

The original concrete job step of mode and each step time spent statistics of drawing in the net is as follows:

1, before the road closure beginning, earlier an end of safe insulation net and wire rope is fixed (preparation before the road closure) on the crossing frame of a side;

2, opposite side is got over and is presetted 4 operation personnel on the coil holder and climb up crossing frame, and everyone carries a rope, and rope one end is fixed in the crossing frame top, and the other end hangs down to ground;

3, implement road closure by the traffic police, after the road closure beginning rapidly with the safe insulation net by speedway one layback to opposite side, two wire rope intersect mutually immediately following the safe insulation net and are pulled through speedway;

4, safe insulation net and wire rope and opposite side are got over the rope that hangs down on the coil holder and are connected reliably, by net up wire rope below order up and down rise and to winch to certain altitude;

5, net and wire rope are tightened to the requirement of satisfying safe stringing, and fix reliably, so far the speedway deblocking;

6, after finishing, receive all air line workings net.(need carry out road closure second time because receive net after circuit stringing finishes, only wire rope and net directly need be got on the coil holder to cut with scissors from an end and get final product, process is simple, time compole weak point)

Adopt said method to implement to draw in the net operation, to the 5th step highway deblocking, total activity duration, wherein the 3rd step needed about 1 minute about 18 minutes since the road closure of the 3rd step, and the 4th step needed about 7 minutes, and the 5th step needed about 10 minutes.In a single day this operating type also has a very big shortcoming, because the safe insulation net twines in the lifting process easily, twines when netting exactly, the so required activity duration increases greatly, sometimes even above 30 minutes.

Summary of the invention

The objective of the invention is to overcome above-mentioned weak point, can shorten the speedway road closure time greatly, save the ascend operation personnel thereby provide a kind of; The road closure time can shorten, to the normally current safe insulation web frame that the speedway of reliable guarantee is provided of safety of vehicle on highway.

According to technical scheme provided by the invention, the safe insulation web frame of speedway comprises safe insulation net, wire rope, crossing frame, feature is: described safe insulation net, wire rope are connected with crossing frame, between the main rope of described network edge and the wire rope shackle are set.The equidistant setting of described shackle.

Compared with the prior art the present invention has the following advantages:

When safe insulation net of the present invention is pulled through speedway aloft, have the people to handle synchronously on crossing frame, the situation that can avoid netting winding takes place; A big chunk workload can be placed under the normally current situation of speedway and carry out, shorten the speedway road closure time greatly, draw in the net the required ascend operation personnel of operation simultaneously also to be reduced to 4, save staff by original 6; Because the shortening of road closure time is to the normal current reliable guarantee that provides of safety of vehicle on highway.

Description of drawings

Fig. 1 is a structural representation of the present invention.

The specific embodiment

Embodiment during following the present invention incites somebody to action in conjunction with the accompanying drawings is further described:

As shown in Figure 1: comprise main rope 3, crossing frame 4 and the shackle 5 of safe insulation net 1, wire rope 2, network edge, described safe insulation net 1, wire rope 2 are connected with crossing frame 4, shackle 5 is set, described shackle 5 equidistant settings between the main rope 3 of described network edge and the wire rope 2.

It is as follows that the present invention draws in the net operating type job step:

1, before speedway road closure, in advance wire rope 2 is winched to a side crossing frame 4 tops together with an end of a reliable nylon rope of intensity, safe insulation net 1 is all winched to a side crossing frame top.

2, opposite side is got over and is presetted 2 operation personnel on the coil holder and climb up crossing frame, and everyone carries a rope, and rope one end is fixed in crossing frame 4 tops, and the other end hangs down to ground;

3, implement road closure by the traffic police, after the road closure beginning with wire rope 2 and the parallel speedway opposite side that is pulled to of nylon rope;

4, the rope that wire rope 2 and nylon rope and coil holder are more hung down reliably is connected and lifts by crane;

5, rise and winch to behind the certain altitude wire rope 2 secure fixation; The nylon rope of controlling well does not make it sagging, so far the speedway deblocking;

6, connect with the nylon rope other end of having passed by on one's way and the safe insulation net 1 that winches to crossing frame 4 tops, utilize this root nylon rope pulling net to pass by on one's way aloft along wire rope;

7, keep certain force of strain in the process that an end operating personnel opposite operating personnel of safe insulation net draws in the net, simultaneously between the main rope 3 of network edge and wire rope 2, add a shackle 5 (utilizing the height in a plurality of fixed points assurance safe insulation net drawing process) at a certain distance;

7, the safe insulation net is pulled through and tightens up behind the speedway and fixing.

8, the operation of receipts net is identical with original method.

New method after the utility model utilization improves implements to draw in the net operation, the activity duration required from the 3rd step to the 5th step is about 6 minutes, the 3rd goes on foot the required time about 30 seconds, and the 4th went on foot the required activity duration about 2 minutes, and the 5th went on foot the required time about 3.5 minutes. The characteristics of the method maximum after the improvement are to have the people to process synchronously in crossing frame when safety insulation net is pulled through highway aloft, the situation that can avoid netting winding takes place, behind the method improvement workload greatly being placed on highway in addition normally carries out in the current situation, greatly shortened the highway road closure time, drawing in the net simultaneously the required ascend operation personnel of operation also is reduced to 4 by original 6, has saved staff. Because the shortening of road closure time provides reliable guarantee to the safety of highway vehicle is normally current, has formed good social influence.
