Description

A safety fence for electric power maintenance and testing

technical field

The utility model relates to electric power construction site safety facilities, in particular to a safety fence for electric power maintenance and testing.

Background technique

With the development of industry, all walks of life have increasingly high requirements for the reliability and stability of power supply of power systems, so more and more attention is paid to the maintenance and repair of power system operation. In the process of maintenance and testing of power equipment, in order to prevent casual personnel from entering the construction site, maintenance personnel often need to set up safety fences to isolate the construction area during construction, so as to prevent personnel from approaching high-voltage live areas and ensure personnel safety.

Now the common isolation fence is to set several uprights, and then pull a few protective belts between the uprights for safety isolation. This isolation method is relatively simple, but because the protective belts are relatively fragile and the stability is not good, the maintenance personnel repeatedly enter and exit the safety protection The process in the area can easily cause the protective belt to break or fall off from the column. The isolation effect is not very good, and there will be safety hazards, and the use of the protective belt is not very convenient. In order to increase the stability and convenience of the safety fence, people have designed a telescopic fence. For example, the utility model patent No. "ZL2013204620409" applied for in China discloses a telescopic fence. It is also more convenient, but there is no connection structure between the fences, and the general power construction area needs to use fences around, so that the connection between the two fences is not very tight, easy to fall or collide, and there are large gaps. It can't play a good isolation effect; in addition, this kind of telescopic fence cannot be fixed after shrinking, and it is not very convenient to carry.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described. As shown in Figure 1 and Figure 3, a safety fence for electric power maintenance and testing includes left and right brackets 1, 2 and telescopic railings 3, and is characterized in that: the left and right brackets are composed of bottom bars 4 The inverted T-shaped bracket formed with the vertical rod 5 is provided with a telescopic railing installation groove 6 vertically on the side where the vertical rod 5 of each bracket is connected to the telescopic railing 3, and the telescopic railing 3 is made of a plurality of sheet-like The insulating rods are cross-connected, similar to a fence shape, and the fence holes are diamond-shaped. On the outside of each sheet-shaped insulating rod, there is a red and white warning layer on one side, which is not only beautiful but also can play a warning role. Both sides of the telescopic railing 3 are respectively embedded in the mounting grooves 6 of the corresponding side brackets, and are fixed by bolts so as not to fall off from the brackets arbitrarily.

As shown in Figures 1 and 2, the bottom of the bottom bar 4 of the left and right brackets is provided with a groove 7 connected to the bottom bar 9 of the adjacent fence, and the groove 7 is equal in length to the width of the bottom bar 4 The square groove is set at the central position of the bottom bar 4, and its cross-section is the same as the cross-sectional size of the bracket bottom bar 9 of the adjacent fence. One end of the bracket bottom bar 9 of the adjacent fence passes through the groove 7 and the left bracket Or the bottom bar 4 of right support is vertically connected, and the bottom bar 9 of adjacent fence after connecting and the bottom bar 4 bottom surfaces of left support or right support are on the same plane.

As shown in Figure 1 and Figure 3, a fixed rod 8 is provided on one of the brackets, and the fixed rod 8 is fixed at the position of 1/2-2/3 height of the vertical rod of the bracket through a rotating shaft, and a bolt hole is opened at the other end , Also offer the bolt hole at the relative position of another support vertical pole, when telescopic railing 3 is in telescopic state, the other end of fixed rod 8 is fixed on the vertical pole of another support by bolt.

When the utility model is in use: each power construction area adopts four fences for maintenance, four fences surround a quadrangle, and then the telescopic railing 3 is pulled apart, and adjacent fence supports are connected through grooves. In order to facilitate the connection of the bottom bars of the adjacent fence brackets to different heights, the section size of the lower bracket bottom bar is the same as that of the groove 7 on the higher bracket bottom bar. The specific connection method is as shown in Figure 2. The bottom bar of the lower bracket passes through the groove on the bottom bar of the higher bracket until the poles of the two adjacent fence brackets touch to ensure that the connection gap between the two brackets is the smallest, which can ensure that the two adjacent fences The tight connection can also ensure that the fence will not fall down at will.

When the utility model is retracted, the telescopic railing 3 is first shrunk together, as shown in Figure 3, the other end of the fixed rod 8 is fixed with the opposite bracket pole, the two brackets are connected, and the entire telescopic railing is fixed. Railing 3 is fixed, can not spread out at will, is convenient to carry and collect.
