Description

Technical Field

[0001] The present invention relates to the technical field of rail transit detection, and in particular to a mounting seat and detection equipment based on rail installation. Background Art

[0002] When a railway train is running on the track, its wheel size needs to be detected online. At present, the detection equipment installed on the track bed in China is the TWDS track detection equipment (Track Wheel Detection System). The installation feature of this detection equipment is that it uses a steel sleeper as the basis. When installing the steel sleeper, it is necessary to remove a cement sleeper on site and replace it. Four detection units are installed on the steel sleeper, and the detection units are located on the inside and outside of the track respectively.

[0003] The installation of existing detection equipment requires the replacement of rail sleepers, which is labor-intensive and time-consuming. In addition, the steel rail sleepers are large in size, which makes on-site installation difficult and requires a long installation period. It is not feasible for situations where the window time is short, and it cannot be quickly restored after disassembly. For ballasted trackbeds, the installation of steel rail sleepers will also affect track maintenance operations such as tamping. Summary of the invention

[0004] In view of this, the present invention provides a mounting base and a detection device based on track installation, aiming to improve the installation convenience of the device and reduce the impact on the original road bed after the installation of the device.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A mounting base based on track installation comprises a frame and a track clip; the frame comprises a crossbar arranged between two adjacent sleepers and located below the track; two track clips are installed on the crossbar and are respectively used to connect with two tracks; at least one of the track clips is movably installed on the crossbar and can move freely on the crossbar.

[0007] In some optional embodiments, it further includes a crossbeam; the crossbeam is arranged on the ballast bed between two adjacent sleepers; and the crossbar is placed on the crossbeam.

[0008] In some optional embodiments, a shock absorbing device is further included; the shock absorbing device is arranged between the cross bar and the cross beam.

[0009] In some optional embodiments, a cable is disposed inside the crossbeam; and a wire hole for the cable to pass through is disposed on the crossbeam.

[0010] In some optional embodiments, an air pipe is provided in the crossbeam, and a vent connected to the air pipe is provided on the crossbeam.

[0011] In some optional embodiments, there are more than two cross bars; adjacent cross bars are connected by brackets.

[0012] In some optional embodiments, the rail clamp includes two clamping claws, and the opposite inner sides of the two clamping claws have clamping grooves; the two clamping claws are connected by bolts.

[0013] In some optional embodiments, the portion of the rail clip that is in contact with the rail has an insulating layer.

[0014] A detection device based on track installation comprises a detection unit and the above-mentioned mounting seat; the detection unit is arranged beside the track and mounted on the crossbar.

[0015] In some optional embodiments, the crossbar is provided with a position limiting mounting seat, and the detection unit is provided with a mounting support used in conjunction with the position limiting mounting seat.

[0016] In summary, compared with the prior art, the present invention has the following advantages and beneficial effects: the frame can be quickly and conveniently installed on the track through the rail clip by using the mounting seat described in the present invention, so the required installation time is short, and the installation is easy, the workload is small, and it can be completed within a short time. When the mounting seat described in the present invention is used as the installation base of the detection equipment, for example, it can be quickly installed, and it is easy to disassemble and assemble, and has high stability. In addition, since at least one rail clip is movably mounted on the crossbar, when the relative position between the two tracks changes, the relative position between the two rail clips can also change accordingly, so that the entire mounting seat can adapt to the gauge deviation and the lateral sliding of the track when the vehicle passes. Since the structure of the original track bed is not destroyed, it will not affect the line maintenance operations such as the tamping of the ballasted track bed, and the original appearance of the line can be quickly restored after the mounting seat is removed.

[0027] Embodiment 1

[0028] like Figure 1 and Figure 2 As shown in FIG. 1 , a rail-mounted mounting base 4 described in an embodiment of the present application includes a frame 42 and a rail card 44. Figure 1 The spatial rectangular coordinate system shown in is used to explain the relevant structures of the present invention, wherein the positive direction of the X-axis is the right, the positive direction of the Y-axis is the front, and the positive direction of the Z-axis is upward.

[0029] like Figure 3 As shown, the frame 42 includes at least one crossbar 421. Figure 1 As shown, the cross bar 421 is arranged between two adjacent sleepers 2 and below the track 3 .

[0030] like Figure 2As shown, two rail clips 44 are installed on each crossbar 421, and the two rail clips 44 are respectively used to connect with the two rails 3. In addition, one rail clip 44 is fixedly installed on the crossbar 421, and the other rail clip 44 is movably installed on the crossbar 421 and can move freely left and right on the crossbar 421. For example, a slide rail is provided on the crossbar 421, and the bottom of the rail clip 44 has a slider used in conjunction with the slide rail. Alternatively, both rail clips 44 are movably installed on the crossbar 421 and can move freely left and right on the crossbar 421.

[0031] The mounting seat 4 described in the embodiment of the present application can be used to quickly and conveniently install the frame 42 on the track 3 through the rail clip 44, so the required installation time is short, and the installation is easy, the workload is small, and it can be completed within a skylight time. When the mounting seat 4 described in the embodiment of the present application is used as the installation base of the detection equipment, for example, it can be quickly installed, and it is easy to disassemble and assemble, and has high stability. In addition, since at least one of the rail clips 44 is movably mounted on the crossbar 421, when the relative position between the two tracks 3 changes, the relative position between the two rail clips 44 can also change accordingly, so that the entire mounting seat 4 can adapt to the gauge deviation and the lateral sliding of the track 3 when the vehicle passes. Since the structure of the original track bed is not destroyed, it will not affect the line maintenance operations such as the tamping of the ballasted track bed, and the original appearance of the line can be quickly restored after the mounting seat 4 is removed.

[0032] In order to further improve the installation stability of the entire mounting base 4, as Figure 2 As shown, the embodiment of the present application may further include at least one crossbeam 41. Figure 1 As shown, the bottom of the crossbeam 41 is placed on the ballast bed 1 between two adjacent sleepers 2, and the crossbar 421 is placed on the crossbeam 41. One crossbeam 41 can be provided corresponding to each crossbar 421. The crossbeam 41 is supported between the ballast bed 1 and the crossbar 421 to provide support for the crossbar 421, so that the crossbar 421 is supported by the ballast bed 1, and the crossbar 421 is prevented from bending downward due to excessive load or excessive force, thereby ultimately ensuring the accuracy of the position of the detection equipment installed thereon.

[0033] Several shock absorbing devices, such as rubber shock absorbers, may be installed between the crossbar 421 and the crossbeam 41. The shock absorbing device may be installed on the crossbeam 41 or the crossbar 421, or may be connected to both the crossbar 421 and the crossbeam 41. The shock absorbing device can reduce the vibration of the crossbar 421 when a vehicle passes by, making the detection equipment installed thereon more stable.

[0034] like Figure 2As shown, the crossbeam 41 can be made of a hollow steel pipe. The advantage is that cables can be laid in the crossbeam 41 to meet the power and communication needs of the detection equipment. A number of wire holes 433 for the cables to pass through can be opened on the crossbeam 41, so that the cables can choose a suitable position to pass through the crossbeam 41 and connect with the detection equipment. An air pipe 431 can also be laid in the crossbeam 41 to meet the functions of blowing, dust removal or air conditioning of the detection equipment. A number of vents 432 connected to the air pipe 431 can be opened on the crossbeam 41 so that a suitable position can be selected to connect with the detection equipment. The cables and air pipes 431 can be both set in one crossbeam 41, or they can be separately set in different crossbeams 41. As shown Figure 3 As shown, the cross bar 421 may also be provided with corresponding wire holes 433 and vents 432 to allow cables and gas to pass through.

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, in order to enhance the stability and structural strength of the frame 42, there may be more than two crossbars 421, and the ends and / or middles of adjacent crossbars 421 may be connected by brackets 422. Adjacent crossbars 421 may be separately arranged in the gaps on the front and rear sides of a sleeper 2, that is, each crossbar 421 occupies a gap between two adjacent sleepers 2. The brackets 422 span the sleepers 2 to connect the crossbars 421, for example, by screwing, so as to facilitate quick installation and removal.

[0036] As an optional implementation, Figure 4 As shown, the rail clamp 44 may include two clamping claws 442, and the inner sides of the two clamping claws 442 are provided with clamping grooves 443. The two clamping claws 442 may be connected by bolts 441, so as to adjust the distance and tightness between the two clamping claws 442.

[0037] In addition, the portion of the rail card 44 that is in contact with the rail 3 has an insulating layer 444, which is to prevent the rails 3 on the left and right sides from being turned on, thereby avoiding the appearance of a red light band due to the use of the mounting seat 4.

[0038] Embodiment 2

[0039] The present application embodiment introduces a detection device based on track installation, such as Figure 5As shown, it includes a detection unit 5 and the mounting base 4 described in Example 1. The detection unit 5 is arranged on the left and right sides of the track 3 and is installed on the crossbar 421. The detection unit 5 can be quickly and conveniently installed on the line through the mounting base 4 described in Example 1, and the installation position is stable and reliable. Since the structure of the original track bed is not damaged, the tamping work of the ballasted track bed will not be affected. The detection unit 5 can have multiple, for example, four, detection units 5, which can be installed one on the left and right sides of each track 3, so as to perform a full range of detection on the bottom of the rail train. The detection unit 5 can be a TWDS mainline detection device, or it can be a device such as the one introduced in Chinese patent CN204301703U.

[0040] In order to further improve the installation accuracy of the detection unit 5 on the mounting base 4, as Figure 3 As shown, a plurality of position limiting mounting seats 423 may be provided on the cross bar 421, and the detection unit 5 may have a mounting support used in conjunction with the position limiting mounting seats 423. During installation, the mounting support of the detection unit 5 is aligned with the position limiting mounting seat 423 on the cross bar 421, so that the installation position of the detection unit 5 is accurate and reliable, and the installation efficiency can be improved, further shortening the installation time.

[0041] The technical features of the above-described embodiments may be arbitrarily combined.
