[0002] Among the railway projects currently under construction in China, ballastless trackbeds such as national railways, subways, and urban railways are generally increasing. There are many installation points for signal track circuit equipment in tunnel sections and roadbed sections. Rail lead wires are the key materials for realizing the electrical connection between the signal system's trackside equipment and the rails, so the protection method of rail lead wires is particularly important.

[0003] Existing fixing brackets consist of two connecting plates and a mounting plate, each hinged to a connecting plate at either end along its length.

After chemical anchor bolts are inserted, one connecting plate is mounted on the ballastless trackbed and the other on the ground near the track. After the lead wires are neatly arranged on the mounting plates, they are secured to the mounting plates with a clamp.

[0004] With respect to the above-mentioned related technologies, the lead wires are not regulated at the line-in and line-out ends of the mounting plate. During long-term use, the relationship between the lead wires and the mounting plate may become loose. Utility Model Content

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-5 This application is described in further detail.

[0036] The embodiment of the present application discloses a rail lead wire fixing bracket. Figure 1 A rail lead wire fixing bracket includes two connecting plates 100 and a mounting plate 200. The mounting plates 200 are hinged to the connecting plates 100 at both ends in the longitudinal direction. The connecting plates 100 are provided with waist-shaped grooves 110 for the passage of expansion bolts. The nuts of the expansion bolts are threadedly connected and tightened against the connecting plates 100. According to the dimensions of the ballastless track bed and the channel edge, the mounting plates 200 can be rotated and adjusted relative to the connecting plates 100, so that one connecting plate 100 is installed on the ballastless track bed via expansion bolts, and the other connecting plate 100 is installed on the channel edge via expansion bolts. The mounting plates 200 are arranged at an angle.

[0037] Reference Figure 1The mounting plate 200 is provided with a first wire groove 210 for positioning and guiding the lead wires. The first wire groove 210 extends along the length direction of the mounting plate 200, and a plurality of first wire grooves 210 are evenly spaced along the width direction of the mounting plate 200. The two connecting plates 100 are both provided with a second wire groove 120. Both the first wire groove 210 and the second groove are arc grooves. The second wire groove 120 corresponds to the first wire groove 210 one by one. A lead wire passes through the second wire groove 120 of the connecting plate 100 and then enters the first wire groove 210. The first wire groove 210 and the second wire groove 120 determine the position of the lead wire on the mounting plate 200 and the connecting plate 100. After the lead wires are arranged and installed on the fixing bracket, the mounting plate 200 is detachably provided with a first clamp 300 for fixing the lead wires, and the connecting plate 100 is detachably provided with a second clamp 400 for fixing the lead wires.

[0038] Reference Figure 2 Specifically, the first fixture 300 includes a first clamping plate 310, and the second fixture 400 includes a second clamping plate 410. Both the first clamping plate 310 and the second clamping plate 410 are provided with a third wire groove 500, which is also an arc groove. When the lead wire is installed on the fixed bracket, the third wire groove 500 can further limit the lead wire.

[0039] Reference Figure 2 The ends of the first clamping plate 310 are bent to form a first connecting block 320. Fixed blocks 220 are mounted on opposite side walls of the mounting plate 200. The first connecting block 320 and the fixed block 220 are fixedly connected via bolts and nuts. Because there is spacing between the first wire ducts 210 and the cross-section of the lead wire is circular, the first wire ducts 210 can accommodate lead wires with diameters within a certain range. If the lead wire diameter is too large, a spacing is left between the first connecting block 320 and the fixed block 220 during the fixed connection. If the lead wire diameter is too small, the first connecting block 320 will fit against the fixed block 220.

[0040] Reference Figure 2 The two ends of the second clamping plate 410 are bent to form a second connecting block 420, which is connected to the connecting block via bolts and nuts. If the lead wire diameter is relatively small, the second connecting block 420 fits on the connecting plate 100. If the lead wire diameter is relatively large, the connecting block does not need to fit on the connecting plate 100. Therefore, the first clamping plate 310 and the connecting plate 100 can be used to accommodate lead wires of different diameters.

[0041] Reference Figure 3Furthermore, the mounting plate 200 is a retractable structure, comprising a first splicing plate 230 and a second splicing plate 240. Both the first splicing plate 230 and the second splicing plate 240 are elongated plate-like structures, with the second splicing plate 240 being slidably mounted on the first splicing plate 230. The first fixture 300 and the first wire duct 210 are both mounted on the second splicing plate 240. The sidewall of the first splicing plate 230, which is away from the second splicing plate 240, is hinged to the connecting plate 100 via a hinge seat. The sidewall of the second splicing plate 240, which is away from the first splicing plate 230, is hinged to the other connecting plate 100 via a hinge seat.

[0042] Reference Figure 2 and Figure 3 Specifically, guide plates 231 extend from both long sides of the first splicing plate 230. A limit portion 232 extends from the side of the guide plate 231 away from the first splicing plate 230. The limit portion 232 is a limit plate that extends along the length of the guide plate 231. The first splicing plate 230, guide plate 231, and limit plate are integrally formed. Baffles 241 are fixedly connected to the long sides of the second splicing plate 240. The fixing block 220 is fixedly mounted on the baffles 241. After the first clamp 300 is installed on the second splicing plate 240, the baffles 241, the first clamp 310, and the second splicing plate 240 form a space for the installation and fixation of the lead wires. When the second splicing plate 240 and the first splicing plate 230 are matched, the baffle 241 extends between the first splicing plate 230 and the limiting portion 232. The guide plate 231 guides the second splicing plate 240 to move or leave only along the length direction of the first splicing plate 230. The limiting portion 232 is used to limit the second splicing plate 240 from separating from the first splicing plate 230 in other directions.

[0043] Reference Figure 4 The baffle 241 contacts the first splicing plate 230 and the limiting portion 232, and a gap is left between the first splicing plate 230 and the second splicing plate 240. This prevents the overlapping portion of the first splicing plate 230 and the second splicing plate 240 from affecting the heat dissipation of the entire mounting plate 200, allowing the mounting plate 200 to dissipate heat evenly. Furthermore, the gap between the first splicing plate 230 and the second splicing plate 240 creates a heat dissipation space and ventilation channel. This prevents heat from accumulating at the overlapping portion of the first splicing plate 230 and the second splicing plate 240, especially in hot summer weather.

[0044] Reference Figure 4 A ventilation slot 233 is provided on the upper surface of the first splicing plate 230 . The ventilation slot 233 not only increases the heat dissipation space, but also reduces the weight of the entire first splicing plate 230 .

[0045] Reference Figure 5Furthermore, a boss 234 is provided on one end of the first splicing plate 230, adjacent to the connecting plate 100. The second splicing plate 240 abuts against the boss 234 as it slides along the first splicing plate 230. The upper surface of the boss 234 is flush with the upper surface of the second splicing plate 240. An auxiliary groove 235 is defined on the boss 234, corresponding one-to-one with the first wire groove 210. Lead wires are mounted on the mounting plate 200, positioned within both the first wire groove 210 and the auxiliary groove 235, ensuring that the lead wires are positioned at the same height on the first and second splicing plates 230, 240.

[0046] The implementation principle of a rail lead wire fixing bracket in the embodiment of the present application is as follows:

[0047] After the mounting plate 200 is positioned through the hinged relationship with the connecting plate 100 and the retractable structure of the mounting plate 200 itself, the two connecting plates 100 are fixed to the ballastless track bed and the edge of the track respectively through expansion bolts. The lead wires can be arranged along the first wire duct 210 and the second wire duct 120 to avoid confusion and intersection; the lead wires are further fixed by the first clamp 300 and the second clamp 400.

[0048] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
