During use, it is easy for people to climb the steel guardrail, resulting in certain safety hazards during use. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that in the prior art, when a steel guardrail is installed in the middle of a road for isolation, the steel guardrail is mostly a sheet structure without a structure to prevent people from climbing. During use, it is easy for people to climb the steel guardrail, resulting in certain safety hazards during use. A steel guardrail with an anti-oxidation coating sprayed on the surface and a production process thereof are proposed.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a steel guardrail with an anti-oxidation coating sprayed on the surface and its production process, comprising two guardrail bodies and railings, a protective device is arranged between one side of the two guardrail bodies and both sides of the railings, a lubrication device is arranged on one side of the guardrail body, the protective device comprises two round rods, a first slide groove is opened on one side of the guardrail body, second slide grooves are opened on both sides of the inner wall of the first slide groove, the two ends of the railing are respectively slidably connected with the inner walls of the two first slide grooves, and the pull rod A spring is symmetrically fixedly connected to one side of the guardrail, one end of the spring is fixedly connected to one side of the inner wall of the first slide groove, tooth plates are symmetrically fixedly connected to both sides of the railing, one end of the tooth plate is slidably connected to the inner wall of the second slide groove, round holes are symmetrically opened on one side of the guardrail body, the round rod is inserted into the inner wall of the round hole, a plurality of protective rods are fixedly connected to the outer surface of the round rod, gears are fixedly connected to both ends of the round rod, the outer surface of the gear is meshed with one side of the tooth plate, and one end of the gear is rotatably connected to one side of the inner wall of the first slide groove.

[0006] The effect achieved by the above components is: by setting the protective device, when the steel guardrail is installed in the middle of the road for isolation use, the railing will be fixed in the middle position of the road with the help of the guardrail body. When someone wants to take a shortcut to climb over the railing, he usually steps on the railing first, which will drive the pull rod to slide downward in the inner wall of the first slide groove, compressing its spring, and at the same time driving the tooth plate to slide downward in the inner wall of the second slide groove, and then driving the two gears to rotate in opposite directions on one side of the inner wall of the first slide groove, so that the two ends of the round rod rotate in the round hole, driving a number of guardrails to rotate and open in opposite directions with the round rod as the center, increasing the shielding area of ​​the guardrail body and the top of the pull rod, so that there is no fulcrum for climbing over, thereby preventing people from climbing and reducing the potential safety hazards in the use process. Similarly, when no people are climbing, the spring will drive the railing to slide and reset in the inner wall of the first slide groove, and then drive the tooth plate and the gear to reset, and at the same time the round rod and a number of protective rods will also reset and shrink, making it easy to carry, and at the same time increasing the isolation height of the two guardrail bodies and the railing.

[0014] The effect achieved by the above components is: by setting up the lubrication device, during the use of the protective device, the oil cover can be opened regularly, and then the lubricating oil can be injected into the lubricating oil tank, and then the oil cover can be closed. The lubricating oil will flow into the oil pipe under the action of gravity, and then flow into the guide frame. When the round rod rotates, it will drive a number of balls to roll in the inner wall of the guide frame, and bring out the internal lubricating oil to smear on the outer surface of the round rod, and lubricate the connection between its surface and the round hole, so as to avoid corrosion and aging of the connection after long-term use, resulting in the inability to rotate, thereby improving the service life of the protective device.

[0015] Preferably, a connecting rope is fixedly connected to one side of the oil cover, and one end of the connecting rope is fixedly connected to one side of the lubricating oil tank.

[0016] The effect achieved by the above components is that the oil cap can be fixed on one side of the lubricating oil tank by arranging the connecting rope, so that it is not easy to be lost when adding lubricating oil.

[0017] Preferably, brackets are fixedly connected to the outer surfaces of both ends of the oil pipe, and one side of the bracket is fixedly connected to one side of the guardrail body.

[0019] Preferably, a plurality of sponge blocks are fixedly connected to the inner wall of the guide frame, and the plurality of sponge blocks are arranged at equal distances.

[0020] The effect achieved by the above components is: by setting the sponge block, when the ball brings the lubricating oil out of the guide frame and smears it on the round rod, the rotation of the round rod will wipe on the sponge block, so that the sponge block can evenly spread the lubricating oil on the round rod, and at the same time can also absorb excess lubricating oil, which is convenient for orderly lubrication operation.
