Abstract

A safety guardrail comprises a horizontal railing, a vertical railing, a vertical upright post and a base, which are connected by a tee and a fitting body. The fitting body is connected into one unit by a left joint arm, a right joint arm and a plinth. The left joint arm and the right joint arm revolve around the plinth in positive direction and in negative direction. The horizontal railing, the vertical railing and the vertical upright post are the composite pipes of fiberglass pipes covered by a covering layer. In order to ensure the normal power supply of electric power system, some rush repair and fault resolution works of electric power substation have to be done with electricity. High pressure threatens personnel safety greatly. In order to work safely, alarm and remind staffs, the safety guardrail is a necessary establishment for the electric power system to do security protection. The horizontal railing, the vertical railing and the vertical upright post of the guardrail are the composite pipes which have good insulation performance, high intensity and good anti-static and anti-ultraviolet ray prevention performance. The fitting body of the guardrail can be revolved in any direction and anywhere in order to change the direction and the position of the guardrail. The guardrail is not influenced by field, shape and position, which can be used conveniently and extensively.

Description

Safety guide rail

Technical field

The present invention relates to a kind of guardrail, when keeping apart charging zone and other deathtrap, use on ground such as particularly a kind of power plant in power system, power station, electric substation, and have good insulation, antistatic performance, can also change the safety guide rail of guardrail position and direction arbitrarily.

Background technology

Guardrail is mainly as separating, separate or make spacer when making accident treatment temporarily and use, can be extensively at traffic safety, urban road, engineering construction, the scene of the accident, public place, beach etc. local the use.

In power system especially in electric substation, for guaranteeing normal power supply, electric substation not only needs frequent maintaining circuit and line fault to get rid of, repairing etc., also necessary hot line job during construction, the operating voltage of electric substation is generally more than 11KV, high voltage causes great threat to personal safety, be safety operation, caution, remind each staff or inoperative personnel, guardrail just becomes a kind of requisite safety device, high voltage region is kept apart the effect of playing caution and guaranteeing safety, but the guardrail that existing power system is used is still the same with conventional guardrail, union is the threeway of fixing, four-way, two structures such as logical can not be rotated, therefore also being fixed by its guardrail that connects into, can only be right-angle turning, also needs could satisfy the corner needs with a plurality of guardrails, use, collection is all inconvenient, in addition also some guardrail only to hang up protective screening on rail bar too simple and crude, can not play effective safety effect at all like this, there is great hidden danger in personal safety.

Patent No. CN200410077229 " a kind of electronic warning guardrail that is used to isolate the deathtrap ", though a kind of guardrail that use the deathtrap of isolating is provided, its structure still is old guard bar structure, just old guardrail is provided with infrared rays correlation electronic installation, and connecting electronic alarm device respectively, caution, the reminding effect of sound and light alarm only arranged.

What patent No. CN01239510.2 " transformer station's protective guard " provided only is to be combined by plastic pipe and plastic elbow, plastic three-way, four-way, plastic hinge, the good insulation preformance of plastics can improve safety, but its other structure is still general guard bar structure commonly used.

Summary of the invention

Technical problem to be solved by this invention is: a kind of safety guide rail is provided; good insulation preformance energy antistatic; also can change the position and the direction of guardrail as required arbitrarily; easy to use, flexible; power plant, power station, the electric substation of suitable especially power system are used for isolated high voltage district or other deathtrap, are used to protect personal safety or play the warning safe effect.

The present invention addresses the above problem the technical scheme that is adopted, safety guide rail, connecting into whole institute by horizontal, straight railing, right cylinder, base through threeway, fittings body forms, the integral body that described fittings body is connected into by left and right joint arm and plinth, the forward and reverse rotation of described left and right joint arm energy solderless wrapped connection headstock, described horizontal stroke, straight railing, right cylinder are that the fiberglass pipe of internal layer covers the composite material tube that covering layer constitutes outward.

Compared with prior art; the invention has the advantages that: because of power system is the assurance normal power supply; so some repairing; the all necessary hot line job of troubleshooting effort; and the operating voltage of electric substation is generally all more than 11KV; and all be open-air operation; high voltage causes great threat to personal safety; be safety operation; caution; remind each staff or inoperative personnel; therefore safety guide rail is that the requisite facility of safeguard protection is carried out in power system; the horizontal stroke of this guardrail; straight railing; right cylinder is clad pipe not only good insulation preformance and intensity height; can also antistatic; antiultraviolet is more than general guardrail function; security protection is good; the main union of this guardrail use can be as required in any direction in addition; rotate on the position; change the position and the direction of guardrail, make it not be subjected to the work-yard shape; the influence of position, its scope of application is wide; easy to use; flexibly, dismounting does not need instrument rapidly.

The specific embodiment

Below in conjunction with accompanying drawing embodiments of the invention are further described.

Left and

right joint arm

1,5 is identical two parts, one side has left and right through

hole

6,7 to cooperate with plinth 2, in addition side has left and right

blind hole

11,12 to cooperate with an end of horizontal bar bar 13, and left and right through hole and left and right blind hole are orthogonal, as Fig. 1, Fig. 2, shown in Figure 3.

Have through hole 3 to cooperate with the right cylinder 16 of railing in the middle of the plinth 2, both sides be symmetrical left and

right ladder post

10,8, and inwall is the ladder blind hole, and there is boss 9 usefulness of the band screw knob 4 that has been threaded the lower front surface centre, as shown in Figure 2.

Left and

right joint arm

1,5 is socketed in respectively on the left and

right ladder post

10,8 in plinth both sides, and flexible connection is integral, and is all made by the engineering plastics of insulation, as Fig. 1, shown in Figure 3.

Left and
