[0032] It needs to be explained that the embodiments and the features in the embodiments in the utility model can be combined with each other without conflict. The utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0033] Example 1

[0034] As Figures 1 to 4As shown, the utility model provides a kind of track detection sensor assembly, including mounting seat 100, mounting seat 100 can be fixed on the upper surface of steel rail bottom by the way of bonding, to guarantee that mounting seat 100 can be firmly bonded on steel rail bottom, before mounting seat 100 bonding, the position of mounting seat 100 pre-installed on steel rail bottom is handled clean, removes dirt and dust etc., then a layer of bonding glue is evenly applied on the bonding surface bottom surface of mounting seat 100, mounting seat 100 is placed to predetermined position, it can be released after light pressure several seconds, after bonding glue is dry and stable, mounting seat 100 is fixed to steel bottom rail bottom.The mounting cavity 102 is formed in mounting seat 100, and the two ends of the mounting cavity 102 are through, that is, the opening of one end of the mounting cavity 102 corresponds to the steel rail bottom, and the opening of the other end of the mounting cavity 102 is vertically upward;At the same time, sensor 103 is installed in the mounting cavity 102, and the sensor 103 is a piezoelectric sensor 103, and adjusting nut 105 is also installed on mounting seat 100, adjusting nut 105 closes the opening of one end of the mounting cavity 102 away from the steel rail bottom, so that sensor 103 is closed in the mounting cavity 102.

[0035] To ensure that the sensor 103 is in close contact with the steel rail bottom, an elastomer 104 is installed at one end of the sensor 103 away from the steel rail bottom before adjusting nut 105 is installed, the elastomer 104 is compressed when adjusting nut 105 is installed, and the force of the elastomer 104 acts on the sensor 103 after adjusting nut 105 is fixed, so as to push the sensor 103 in close contact with the steel rail bottom, so that the sensor 103 is always in close contact with the steel rail bottom, and the sensor 103 is always in contact with the steel rail bottom, to ensure that the sensor 103 can detect the state of the steel rail in time. In this embodiment, the elastomer 104 preferably uses a wave spring, of course, the elastomer 104 can also use a disc spring, a rubber body, etc.

[0036] In this embodiment, as shown in the figure, Figure 1 、 Figure 2 、 Figure 3As shown, the mounting base 100 has a sleeve structure 101, which is an integral structure with the mounting base 100, and the two ends of the sleeve structure 101 penetrate the upper and lower surfaces of the mounting base 100. One end of the sleeve structure 101 is flush with the bonding surface of the mounting base 100, and the other end of the sleeve structure 101 penetrates the mounting base 100 and extends upward. At this time, the mounting cavity 102 is the inner cavity of the sleeve structure 101. Meanwhile, the end of the sleeve structure 101 away from the bonding surface of the mounting base 100 has an internal thread, and the adjusting nut 105 has an external thread matched with the internal thread, so that the adjusting nut 105 and the sleeve structure 101 can be connected and separated through the threads. Of course, the external thread can also be arranged on the end of the sleeve structure 101 away from the bonding surface of the mounting base 100, and the internal thread matched with the external thread can be arranged on the adjusting nut 105. In order to facilitate the lead-out of the lead of the sensor 103, the sleeve structure 101 also has a wire outlet hole or wire outlet pipe for the lead-out of the lead of the sensor 103.

[0037] In order to ensure that rainwater cannot enter the mounting cavity 102 from the gap between the mounting base 100 and the rail bottom, as shown, Figure 4 the bonding surface of the mounting base 100 is also provided with a sealing ring 107, which is located outside the mounting cavity 102. In order to facilitate the installation of the sealing ring 107, the bonding surface of the mounting base 100 can also be provided with an annular groove, and the sealing ring 107 is installed in the annular groove. The sealing ring 107 is compressed, and the sealing ring 107 installed in the annular groove is slightly higher than the bonding surface of the mounting base 100. In order to facilitate the installation of the sealing ring 107, an annular step can also be arranged at the end of the mounting cavity 102 close to the bonding surface of the mounting base 100, and the sealing ring 107 is installed in the annular step. In this embodiment, by arranging the sealing ring 107 on the bonding surface of the mounting base 100, the coupling agent applied between the sensor 103 and the rail bottom during installation can be prevented from being lost for a long time, and the output signal of the sensor 103 is more stable.

[0038] In order to make the bonding effect of the bonding glue on the bonding surface of the mounting base 100 better, as shown, Figure 4 the bonding surface of the mounting base 100 can be provided as a friction surface, for example, a grid-shaped groove is arranged on the bonding surface of the mounting base 100, or a plurality of convex points are uniformly arranged on the bonding surface of the mounting base 100.

[0039] In this embodiment, when multiple sensors 103 need to be arranged at the same time, as shown, Figure 1 , Figure 2 , Figure 3As shown, the mounting cavity 102 for mounting the sensor 103 can be multiple, that is, the sleeve structure 101 on the mounting base 100 is multiple, at this time, the multiple sleeve structures 101 can be uniformly spaced along the length direction of the mounting base 100, and the multiple sensors 103 are mounted in the multiple mounting cavities 102 one by one, and then an elastomer 104 is mounted on the top of each sensor 103, and finally the multiple adjusting nuts 105 are tightened on the multiple sleeve structures 101 one by one. When the mounting base 100 has multiple sleeve structures 101, in order to avoid rainwater and the like entering each mounting cavity 102 from the gap between the bonding surface of the mounting base 100 and the rail bottom, at this time, the sealing ring 107 mounted on the bonding surface of the mounting base 100 can also be multiple, and the multiple sealing rings 107 are respectively located at the periphery of the multiple mounting cavities 102, so that each mounting cavity 102 is independently separated; of course, when it is only necessary to ensure that rainwater and the like cannot enter the mounting cavity 102 from the gap between the bonding surface of the mounting base 100 and the rail bottom, and the multiple mounting cavities 102 do not need to be separated, the sealing ring 107 can be only one, at this time, a ring groove can be formed at the periphery of the multiple mounting cavities 102, and then the sealing ring 107 is mounted in the ring groove. In the embodiment, the arranged sensor 103 is two, of course, the arranged sensor 103 can also be three, four or the like according to needs.

[0040] As shown in the embodiment, Figure 2 , Figure 3 When the sensor 103 is multiple, in order to avoid that the vibration of the rail is transmitted to the sensor assembly, causing the adjusting nut 105 in the sensor assembly to loosen due to vibration, a loosening prevention card 106 can also be formed between the two adjacent adjusting nuts 105, and the two adjusting nuts 105 are connected through the loosening prevention card 106, so that the two adjusting nuts 105 cannot rotate on the sleeve structure 101, thereby effectively preventing the loosening of the adjusting nut 105.

[0041] In order to facilitate the loosening prevention card 106 to be clamped on the adjusting nut 105, a plurality of clamping grooves extending along the axis direction of the adjusting nut 105 are formed on the outer wall of the adjusting nut 105, the plurality of clamping grooves are uniformly spaced along the circumferential direction of the adjusting nut 105, and one end of the clamping groove penetrates the top of the adjusting nut 105, so that when the loosening prevention card 106 needs to be clamped between the two adjusting nuts 105, the end of the loosening prevention card 106 can be clamped into the opening end of the clamping groove.

[0042] When the track detection sensor assembly provided in this embodiment needs to be installed, the position on the bottom of the rail to be installed with the mounting base 100 is cleaned. Two sealing rings 107 are installed into the two annular grooves on the bonding surface of the mounting base 100. Then, a layer of adhesive is evenly applied to the bonding surface of the mounting base 100, and the mounting base 100 is placed in the predetermined position. After pressing lightly for a few seconds, it is released. After the adhesive dries and stabilizes, the mounting base 100 is fixed to the upper surface of the rail bottom. Next, a sensor 103 is installed in each of the two mounting cavities 102. An elastic body 104 is placed on the top of each of the two sensors 103. Then, the adjusting nut 105 is placed on the sleeve assembly. Finally, the adjusting nut 105 is turned. After the output signal of the sensor 103 reaches the expected effect, the turning of the adjusting nut 105 is stopped. Anti-loosening clips 106 are installed in the two corresponding slots on the two adjusting nuts 105 to prevent the adjusting nuts 105 from loosening during rail vibration.

[0043] Example 2

[0044] like Figures 5 to 7 As shown, this embodiment 2 provides an installation structure for a track detection sensor assembly, including the sensor assembly as in embodiment 1, and a clamp body 200 for clamping onto the bottom of the rail. The clamp body 200 has a mounting hole 202. When the clamp body 200 is clamped onto the bottom of the rail, the mounting hole 202 is located above the bottom of the rail, and the shape of the mounting hole 202 is adapted to the shape of the mounting seat 100 in the sensor assembly. The size of the mounting hole 202 is slightly larger than the size of the mounting seat 100. One end of the mounting hole 202 passes through the bayonet of the clamp body 200, and the other end of the mounting hole 202 passes through the upper surface of the clamp body 200. The sensor assembly is located inside the mounting hole 202, and a clamp cover 204 for covering the sensor assembly is also installed on the top of the clamp body 200. The clamp cover 204 closes the mounting hole 202 while covering the sensor assembly.

[0045] To prevent the clamp body 200 from vibrating along with the rail and causing the sensor assembly to vibrate, such as Figure 6As shown, a rubber cushion 203 is also arranged between the top of the sensor assembly and the top of the clamp upper cover 204, which not only ensures that the clamp upper cover 204 can be tightly pressed against the sensor assembly while being fixed, but also effectively prevents the vibration of the rail from being transmitted to the sensor assembly, thereby ensuring the detection accuracy of the sensor 103 in the sensor assembly. Meanwhile, in order to avoid that the clamp body 200 drives the sensor assembly to vibrate while the rail vibrates, a certain gap is arranged between the periphery of the mounting seat 100 and the hole wall of the mounting hole 202, so that after the mounting seat 100 is bonded to the rail bottom, the mounting seat 100 is not in direct contact with the clamp upper cover 204. Meanwhile, sealing glue is also arranged in the gap between the periphery of the mounting seat 100 and the hole wall of the mounting hole 202, which not only prevents the clamp body 200 from driving the sensor assembly to vibrate while the rail vibrates, but also prevents rainwater, dust and the like from entering the mounting hole 202, thereby avoiding damage to the sensor assembly. Of course, in the embodiment, the periphery of the mounting seat 100 and the inner wall of the clamp body 200 can also not be injected with sealing glue, in which case, a certain gap is reserved between the periphery of the mounting seat 100 and the inner wall of the clamp body 200, which can also prevent the clamp body 200 from driving the sensor assembly to vibrate while the rail vibrates, and although the sealing performance of the mounting hole 202 is insufficient in this case, the sensor 103 itself will not be damaged too much.

[0046] In order to prevent rainwater from entering the mounting hole 202 through the gap between the clamp upper cover 204 and the top of the clamp body 200, as shown in Figure 7 The top surface of the clamp body 200 can also be provided with a waterproof boss, which is located outside the mounting hole 202. When the clamp upper cover 204 is arranged on the top of the clamp body 200, the lower end surface of the clamp upper cover 204 cooperates with the waterproof boss to form a water stop structure, thereby preventing rainwater from entering the mounting hole 202. Of course, in order to prevent rainwater from entering the mounting hole 202 through the gap between the clamp upper cover 204 and the top of the clamp body 200, the clamp upper cover 204 can also be directly arranged on the upper part of the clamp body 200 when it is arranged, in which case, the lower end surface of the clamp upper cover 204 is lower than the top surface of the clamp body 200. This design can also effectively prevent rainwater from entering the mounting hole 202.

[0047] In order to stably arrange the clamp upper cover 204 on the clamp body 200, as shown in Figure 5 , Figure 6As shown, bolt holes 205 are formed in the top of the clamp body 200 and the clamp upper cover 204, and bolts 205 are screwed into the bolt holes 205 in the clamp upper cover 204 and the clamp body 200 to connect the clamp upper cover 204 and the clamp body 200. Since the rail vibrates when the train runs on the rail, the rail transmits the vibration to the clamp body 200. Therefore, to prevent the clamp upper cover 204 from loosening, anti-loosening plates 206 are penetrated through the two bolts 205 on the same side of the clamp upper cover 204, and split pins 210 are radially inserted into the top of the bolts 205.

[0048] In the embodiment, to facilitate the installation of the clamp body 200 and the sensor assembly, as shown in Figure 6 、 Figure 7 , the upper part of the clamp body 200 is designed in a U shape. At this time, the mounting hole 202 in the upper part of the clamp body 200 is open, the opening of the upper part of the clamp body 200 faces the rail web, and the opening width of the upper part of the clamp body 200 is greater than the length of the mounting seat 100. When the clamp body 200 is clamped on the rail bottom, the sensor assembly is clamped into the opening of the upper part of the clamp body 200, so that the sensor assembly is not collided by the clamp body 200 during installation. In addition, to ensure the closure of the mounting hole 202, a clamp embedded block 201 is installed at the opening of the upper part of the clamp body 200. When the embedded block is inserted into the opening of the upper part of the clamp body 200, the opening of the upper part of the clamp body 200 is closed to form the mounting hole 202, so that the sensor assembly is surrounded by the upper part of the clamp body 200 and the clamp upper cover 204. It should be noted that, in the embodiment, the upper part of the clamp body 200 and the lower part of the clamp body 200 refer to the part of the clamp body 200 above the rail bottom after the clamp is installed on the rail bottom.

[0049] To make the installation of the clamp body 200 more stable, as shown in Figure 5 、 Figure 6 , the installation structure provided in the embodiment further includes a clamp hook 207, which is clamped on the other side of the rail bottom, so that the clamp body 200 and the clamp hook 207 are symmetrically arranged on the rail bottom. In addition, the clamp hook 207 has a screw rod 208 extending to the lower part of the clamp body 200, and the lower part of the clamp body 200 has a through hole matched with the screw rod 208. After the screw rod 208 is penetrated through the through hole in the lower part of the clamp body 200, an anti-loosening nut 209 is screwed. To prevent the anti-loosening nut 209 from falling off, the tail of the screw rod 208 is also penetrated by a split pin 210. It should be noted that, in the embodiment, the lower part of the clamp body 200 refers to the part of the clamp body 200 below the rail bottom after the clamp is installed on the rail bottom.

[0050] In the present embodiment, in order to facilitate the lead of the sensor 103 to be smoothly led out of the clamp body 200, as shown in Figure 6 、 Figure 7 shown, the clamp body 200 and the clamp upper cover 204 are provided with a cable joint protection tube 211 in common, that is, one half of the cable joint protection tube 211 is located on the clamp body 200, and the other half of the cable joint protection tube 211 is located on the clamp upper cover 204, when the clamp body 200 is fixed with the clamp upper cover 204, the cable joint protection tube 211 on the clamp body 200 is buckled with the cable joint protection tube 211 on the clamp upper cover 204 to form a complete cable joint protection tube 211. Of course, in the present embodiment, the cable joint protection tube 211 can also be provided only on the clamp upper cover 204 or the clamp body 200, at this time, the cable joint protection tube 211 on the clamp upper cover 204 or the clamp body 200 is a complete cable joint protection tube 211.

[0051] In the present embodiment, when the sensor assembly is installed on the rail bottom in the manner of embodiment 1, the clamp insert block 201 is removed from the clamp body 200, the opening on the clamp body 200 is corresponded with the sensor assembly, the clamp body 200 is clamped on one side of the rail bottom, and the clamp body 200 installs the mounting seat 100 in the sensor assembly in the opening on the clamp body 200 at the same time; then, the clamp hook 207 is clamped on the other side of the rail bottom, and the screw rod 208 on the clamp hook 207 is penetrated through the through hole on the clamp body 200, the lock nut 209 is tightened on the tail of the screw rod 208, and the split pin 210 is penetrated through the opening on the tail of the screw rod 208 in the radial direction; then, the clamp insert block 201 is inserted into the clamp body 200, the sealant is injected into the gap between the clamp body 200 and the mounting seat 100 and the gap between the clamp insert block 201 and the mounting seat 100, the rubber cushion 203 is placed on the top of the sensor assembly or is pasted on the inner top of the clamp upper cover 204, the clamp upper cover 204 is covered on the top of the clamp body 200, the bolts 205 are commonly screwed into the bolt holes on the clamp upper cover 204 and the clamp body 200, the lock plates 206 are commonly sleeved on the two bolts 205 on the same side of the clamp upper cover 204 after the bolts 205 are tightened, and finally the split pin 210 is penetrated through the opening on the head of the bolt 205 in the radial direction.

[0052] In the embodiment, the sensor assembly is installed first, and then the clamp body 200, the clamp hook 207 and the like are installed, so that the sensor assembly is fixed, the clamp body 200 can also protect the sensor assembly, the elastic contact or the small gap between the sensor assembly and the clamp body 200 can block the conduction of external force to the sensor 103, the service life of the sensor 103 is increased, the installation of the clamp body 200 provides a relatively stable environment for the internal sensor assembly, has the effects of dustproof and waterproof, can prevent or slow down the volatilization and loss of the coupling agent between the sensor 103 and the rail bottom, and keeps the long-term stable output of the sensor 103 signal.
