Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The embodiment is as follows: referring to fig. 1-4, the protection device for the railway catenary comprises two first columns 1. The two first vertical columns 1 can be any one of the columns in the prior art, such as a metal cylinder.

A plurality of evenly arranged circular supports 2 are arranged on the two first upright posts 1. The plurality of circular brackets 2 may be pipe clamps in the prior art, such as plastic pipe clamps, and are fixedly mounted on the first upright 1 by a fixing method in the prior art, such as bolt screwing.

A plurality of circular brackets 2 on the same first upright post 1 are sleeved with water leakage pipes 3. The drain pipe 3 may be a water pipe of the prior art, such as a PVC pipe.

The top ends of the two first upright posts 1 are fixedly provided with the same top frame 5. The top frame 5 may be made of various materials known in the art, such as square steel, and is fixedly connected by one of the known methods, such as welding or bolting.

A ceiling 15 and a plurality of second uprights 10 are fixedly mounted to the top side of the top frame 5. The ceiling 15 may be any one of a number of flat plates, such as steel plates, and the second upright 10 may be any one of a number of bars, such as metal bars, connected to the top frame 5 by any one of a number of techniques, such as welding.

The four edges of the ceiling 15 are fixedly provided with a front guardrail 6, a rear guardrail 13 and two side guardrails 14 respectively. The front guard rail 6, the rear guard rail 13 and the two side guard rails 14 are connected to the ceiling 15 by any one of the prior art techniques, such as welding.

The top surface of the ceiling 15 is provided with water leakage holes 16 at positions close to the two side guardrails 14 and the rear guardrail 13, and the two water leakage holes 16 correspond to the two water leakage pipes 3 respectively. The two water leakage holes 16 are positioned at the lowest points of the two sides of the ceiling 15, so that the rainwater on the ceiling 15 can flow out through the water leakage pipe 3 conveniently.

The top end positions and the middle positions of the second upright columns 10 are fixedly provided with tensioning frames 11.

The two tensioning frames 11 are respectively provided with a first elastic rope net 12 and a second elastic rope net 18. The first elastic rope net 12 and the second elastic rope net 18 may be a protective net with certain elasticity in the prior art, such as a nylon rope net.

Based on above structure, ceiling 15 is the slope form, the thing such as the stone that falls drops is on the first elasticity rope net 12 that is in the top, elasticity cushioning effect through first elasticity rope net 12, make the stone that falls slow down, setting through the second elasticity rope net 18 that sets up, can provide the secondary buffering to the great stone of weight, in order to protect ceiling 15 directly to receive the great impact force of stone to pound or puncture, preceding guardrail 6, back guardrail 13 and two side guardrails 14 can block the top that the stone was stayed ceiling 15, prevent directly to fall to pound and injure passerby, if meet rainy day, the rainwater can follow the ceiling 15 trickling of slope, 3 trickles to ground through two water leakage pipes.

In this embodiment, the mesh of second elasticity fag end net 18 is less than first elasticity fag end net 12, the benefit that sets up like this is, first elasticity fag end net 12 is different with the elasticity of second elasticity fag end net 18, the size of stone is once screened through first elasticity fag end net 12 mesh, make first elasticity fag end net 12 mainly bear the great stone impact force of volume, make second elasticity fag end net 18 mainly bear the relatively less stone impact force of volume, play better protection in order to canopy 15, can make first elasticity fag end net 12 and second elasticity fag end net 18 obtain make full use of simultaneously.

In this embodiment, there are 4 inclined supports before two first stands 1 and top frame 5 respectively fixed mounting, do benefit to and provide better supporting role to top frame 5 to bear the impact force of falling the stone.

In this embodiment, the top frame 5 is an inclined surface, and one side of the installed rear guardrail 13 is lower than one side of the installed front guardrail 6, so that the top surface of the ceiling 15 installed on the top frame 5 is inclined, and rainwater can flow more favorably.

In this embodiment, the equal fixed mounting in bottom of two first stands 1 has fixed plate 7, has all seted up a plurality of mounting holes 8 on two fixed plates 7, the installation and the fixing of the first stand 1 of being convenient for.

In this embodiment, one side of ceiling 15 is equipped with ladder 9, and the operator of being convenient for climbs to ceiling 15's top, debris such as the stone of clearance falling.

In this embodiment, one side of rear guardrail 13 is equipped with a plurality of dead levers 17, can be with ceiling 15 and tunnel portal lateral wall fixed connection through a plurality of dead levers 17, makes protector more firm, can reduce the distance of protector and tunnel portal lateral wall simultaneously, the better object of accepting falling.

This practical theory of operation: objects such as the stone that falls pass through on first elasticity fag end 12 with the elasticity cushioning effect of second elasticity fag end 18, make the stone that falls slow down, dual fag end can provide the secondary buffering to the great stone of weight, protection ceiling 15 directly receives the great impact force of stone to pound in or puncture, the railway contact net of below both can be protected like this, can reduce ceiling 15 again to the high requirement of material, protector's manufacturing cost has directly been reduced, the transportation degree of difficulty of material has been reduced simultaneously, setting through a plurality of guardrails, can block the top that the stone was stayed ceiling 15, prevent directly to fall to pound and injure passerby, if meet rainy day, the rainwater can follow the ceiling 15 trickling of slope, 3 trickles to ground through two weeping pipes.

The size of stone is once screened through first elasticity rope net 12 mesh, make first elasticity rope net 12 mainly bear the great stone impact force of volume, make second elasticity rope net 18 mainly bear the relatively less stone impact force of volume, play better protection to canopy 15, can make first elasticity rope net 12 and second elasticity rope net 18 obtain make full use of simultaneously, can be with ceiling 15 and tunnel mouth lateral wall fixed connection through a plurality of dead levers 17, make protector more firm, can reduce the distance of protector and tunnel mouth lateral wall simultaneously, the better object that falls of accepting.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
