Abstract

An electronic tag (Radio-frequency identification) device for a rail traffic concrete prefabricated parts is disclosed, which comprises a bracket. A column is on a top of the bracket. There is a groove on a top end of the column. The electronic tag is inside groove. The electronic tag device further comprises a waterproof end cap which is put on the top of the column. The pressure relief holes, the release-proof clasps, the rebar clamps, the groove on the column, etc. ensure a stable fixation of the electronic tag inside the concrete railroad sleeper. The waterproof end cap is able to protect and fix the electronic tag.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Embodiment 1

[0025] Referring to FIG. 1 of the drawings, an electronic tag device for a rail traffic concrete prefabricated parts, comprising a bracket 1, a column 2 and a waterproof end cap 4; wherein the bracket 1 is in a U shape; the bracket comprises a left foot, a right foot and a beam; a fixing plate is integrated under the beam; a left end and a right end of the fixing plate is connected to the left foot and the right foot; there are reinforcing stiffeners 7 between the fixing plate and the bracket 1; the fixing plate and the reinforcing stiffeners 7 are able to enhance the structural strength of the bracket 1 and prevent shaking during concrete pouring. Pressure relief holes 5 are on the fixing plate, which enables a free flow of the concrete through the two sides of the bracket and prevent shakings caused by the uneven concrete pressure on the left and right side of the bracket. A rebar clamp 8 is on the two feet of the bracket 1 respectively. The rebar clamp 8 is an elastic plastic clamp, which is able to be clipped on the welded steel frame of the precast concrete and fix bracket. The column 2 is on the top of the beam of the bracket 1. A groove is on the top of the column 2. The electronic tag 3 is inside the groove. The waterproof end cap 4 is on the top of the column 2. The column 2 is a cylinder. The inside of waterproof end cap 4 matches the column 2. There are arranged concaves outside of the column 2. The concrete flows into the arranged concaves after the concrete pouring to further fix the column 2. There are release-proof clasps 6 outside of the waterproof end cap 4. The release-proof claps 6 are trigonal pyramidal bulges. The release-proof claps are for fixing the waterproof end cap 4. There are two coils of ultrasonic line 9 inside the waterproof end cap on the top (as shown in FIG. 2). After confirming the electronic tag is working normally, the waterproof end cap 4 is integrated with the column 2 by the ultrasonic thermo-bonding.

[0026] The method for using the device comprises the following steps:

[0027] step 1: checking whether the electronic tag is able to respond normally; if not, replace the electronic tag with a normal one;

[0028] step 2: capping the waterproof end cap with the column; thermo-bonding the waterproof end cap with the column by an ultrasonic welding machine;

[0029] step 3: placing the bracket in the mold of the rail traffic concrete prefabricated parts; fixing the bracket on the welded steel frame by the two rebar clamps; and

[0030] step 4: concrete pouring the mold of the rail traffic concrete prefabricated parts to level the top end of the waterproof end cap with the rail traffic concrete prefabricated parts and achieve an end product of the rail traffic concrete prefabricated parts.

Embodiment 2

[0031] Referring to FIG. 3 of the drawings, an electronic tag device for a rail traffic concrete prefabricated parts, comprising a bracket 1, wherein the bracket 1 is in a U shape; the bracket comprises a left foot, a right foot and a beam; a fixing plate is integrated under the beam; a left end and a right end of the fixing plate is connected to the left foot and the right foot; there are reinforcing stiffeners 7 between the fixing plate and the bracket 1; Pressure relief holes 5 are on the fixing plate. A rebar clamp 8 is on the two feet of the bracket 1 respectively. The column 2 is on the top of the beam of the bracket 1. A groove is on the top of the column 2. The electronic tag 3 is inside the groove. The waterproof end cap 4 is on the top of the column 2. The column 2 is a cuboid. The inside of waterproof end cap 4 matches the column 2. There are arranged concaves outside of the column 2. There are release-proof clasps 6 outside of the waterproof end cap 4. The release-proof claps 6 are trigonal pyramidal bulges. There are two coils of ultrasonic line inside the waterproof end cap on the top.

[0032] One skilled in the art will understand that the embodiment of the present invention as shown in the drawings and described above is exemplary only and not intended to be limiting. Any minor modifications and alterations based on present invention are within the protection range of the present invention.
