[0034] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0035] like Figure 1-Figure 8 As shown, the track inspection vehicle 1 according to the embodiment of the present invention includes a crossbeam 10 , a first support arm 20 , a second support arm 30 , a first stabilizing bar 40 , a second stabilizing bar 50 and a push rod 60 .

[0036] The cross beam 10 is Figure 1 The first support arm 20 and the second support arm 30 are respectively arranged in the width direction (of the cross beam 10) of the cross beam 10. Figure 1 The first support arm 20 is detachably connected to one side surface of the first end of the beam 10, and the second end of the first support arm 20 is away from the beam 10. The first end of the second support arm 30 is detachably connected to the other side surface of the first end of the beam 10, and the second end of the second support arm 30 is away from the beam 10.

[0037] Specifically, Figure 1 As shown, the first support arm 20 is located on the left side of the beam 10, the second support arm 30 is located on the right side of the beam 10, the right end of the first support arm 20 is connected to the left side surface of the beam 10, and the left end of the second support arm 30 is connected to the right side surface of the beam 10.

[0038] One end of the first stabilizing bar 40 ( Figure 1 The front end of the first stabilizing rod 40 is detachably connected to the second end of the first supporting arm 20 ( Figure 1 The left end of the first support arm 20), the other end of the first stabilizing bar 40 ( Figure 1The rear end of the first stabilizing rod 40 is detachably connected to the cross beam 10, and the connection between the first stabilizing rod 40 and the cross beam 10 is adjacent to the second end ( Figure 1 The first stabilizer bar 40 is arranged at the rear end of the middle cross beam 10). Thus, the first stabilizer bar 40 can be used to support the first support arm 20 and prevent the first support arm 20 from swinging. And by arranging the connection between the first stabilizer bar 40 and the cross beam 10 close to the second end of the cross beam 10, the first stabilizer bar 40 can have a larger moment, thereby improving the reliability of the first stabilizer bar 40 supporting the first support arm 20. Preferably, the first stabilizer bar 40 is connected to the first support arm 20 by a screw.

[0039] One end of the second stabilizing bar 50 ( Figure 1 The front end of the second stabilizing rod 50) and the second end of the second support arm 30 ( Figure 1 The right end of the second support arm 30 in the middle is detachably connected, and the other end of the second stabilizing rod 50 ( Figure 1 The rear end of the second stabilizing rod 50 is detachably connected to the cross beam 10, and the connection between the second stabilizing rod 50 and the cross beam 10 is adjacent to the second end ( Figure 1 The second stabilizing bar 50 is symmetrically arranged with the first stabilizing bar 40 about the cross beam 10. It can be understood that the second stabilizing bar 50 can support the second support arm 30, and its working principle is the same as that of the first stabilizing bar 40, which will not be repeated here.

[0040] Therefore, the crossbeam 10, the first stabilizer bar 40, the second stabilizer bar 50, the first support arm 20 and the second support arm 30 are independent structural components, and the connections between the above structural components are all detachable, so it can be understood that the track inspection vehicle 1 in the present application is composed of a plurality of completely separate structural components.

[0041] According to the track inspection vehicle of the embodiment of the present invention, the track inspection vehicle is composed of a first support arm, a second support arm, a first stabilizer bar and a second stabilizer bar which are independent of each other, and the first support arm and the second support arm are both detachably connected to the cross beam, the first stabilizer bar is detachably connected to the first support arm and the cross beam, and the second stabilizer bar is detachably connected to the second support arm and the cross beam. When transporting the track inspection vehicle, the track inspection vehicle can be disassembled into multiple parts that are easy to transport, thereby reducing the difficulty of transporting the track inspection vehicle, minimizing the constraints of road conditions on the transportation path, and making the track inspection vehicle suitable for use in environments such as subway tracks that are difficult to get on and off, and after being transported to the destination, on-site assembly is convenient and does not consume work time.

[0042] Furthermore, if Figure 1-Figure 4 As shown, one side of the beam 10 ( Figure 2A plurality of first guide pins 101 arranged at intervals are provided on the left side of the middle cross beam 10, a first end of the first support arm 20 has a first connecting portion (not shown), a plurality of first guide holes (not shown) arranged at intervals are provided on the first connecting portion, and the plurality of first guide pins 101 are correspondingly matched in the plurality of first guide holes, and the other side of the cross beam 10 ( Figure 3 A plurality of second guide pins 102 arranged at intervals are provided on the right side surface of the middle cross beam 10, the first end of the second support arm 30 has a second connecting portion 305, and a plurality of second guide holes 301 (not shown) arranged at intervals are provided on the second connecting portion 305, and the plurality of second guide pins 102 are correspondingly matched in the plurality of second guide holes 301.

[0043] like Figure 1-Figure 3 As shown, the right end of the first support arm 20 has a first connecting portion, and a plurality of spaced first guide holes are provided on the right side surface of the first connecting portion. When the first support arm 20 is connected to the crossbeam 10, the assembly of the first support arm 20 and the crossbeam 10 can be guided by the cooperation of the first guide pin 101 and the first guide hole, and the cooperation of the first guide pin 101 and the first guide hole also has the function of assembly positioning, so as to accurately assemble the first support arm 20 in the correct position.

[0044] like Figure 3 and Figure 4 As shown, the left end of the second support arm 30 has a second connecting portion 305, and a plurality of spaced second guide holes 301 are provided on the left side surface of the second connecting portion 305. When the second support arm 30 is connected to the crossbeam 10, the second guide pin 102 and the second guide hole 301 can guide the assembly of the second support arm 30, and the cooperation of the second guide pin 102 and the second guide hole 301 also has the function of assembly positioning, so as to accurately assemble the second support arm 30 in the correct position.

[0045] In some embodiments, Figure 4 As shown, the track inspection vehicle 1 also includes a plurality of first wear-reducing sleeves (not shown) and a plurality of second wear-reducing sleeves 304. The plurality of first wear-reducing sleeves are correspondingly matched in the plurality of first guide holes, and the first wear-reducing sleeves are sandwiched between the first guide pin 101 and the inner wall of the first guide hole. Thus, when the first guide pin 101 is matched with the first guide hole, the first wear-reducing sleeve can be wrapped around the outer periphery of the first guide pin 101, thereby avoiding contact wear between the first guide pin 101 and the first guide hole, and improving the reliability of the matching between the first guide pin 101 and the first guide hole and the service life of the components.

[0046] The plurality of second wear-reducing sleeves 304 are correspondingly matched in the plurality of second guide holes 301, and the second wear-reducing sleeves 304 are sandwiched between the second guide pin 102 and the inner wall of the second guide hole 301. Therefore, when the second guide pin 102 is matched with the second guide hole 301, the second wear-reducing sleeve 304 can be wrapped around the outer periphery of the second guide pin 102, thereby avoiding contact wear between the second guide pin 102 and the second guide hole 301, and improving the reliability of the matching between the second guide pin 102 and the second guide hole 301 and the service life of the components.

[0047] In some embodiments, Figure 3 and Figure 4 As shown, the first connection part is provided with a plurality of first through holes (not shown) arranged at intervals, the second connection part 305 is provided with a plurality of second through holes 302 arranged at intervals, and the track inspection vehicle 1 further comprises a plurality of first screws (not shown) and a plurality of second screws 303, the plurality of first screws correspondingly pass through the plurality of first through holes and extend into the cross beam 10, and the plurality of second screws 303 correspondingly pass through the plurality of second through holes 302 and extend into the cross beam 10. It can be understood that after the first support arm 20 and the cross beam 10 are assembled through the pin hole, the first screws can be used for fixed connection, and after the second support arm 30 and the cross beam 10 are assembled through the pin hole, the second screws 303 can be used for fixed connection. In addition, the screws as connecting parts have the characteristics of fastening connection and easy disassembly.

[0048] Furthermore, if Figure 3 and Figure 4 As shown, the track inspection vehicle 1 also includes a first anti-detachment spring (not shown) and a second anti-detachment spring 306. The first anti-detachment spring is clamped on the first screw to prevent the first screw from being separated from the first connecting part, and the second anti-detachment spring 306 is clamped on the second screw 303 to prevent the second screw 303 from being separated from the second connecting part 305.

[0049] In some embodiments, Figure 2 , Figure 6 and Figure 7 As shown, the cross beam 10 is provided with a first stabilizer bar support 103 and a second stabilizer bar support (not shown), and the other end of the first stabilizer bar 40 ( Figure 1 The rear end of the first stabilizer bar 40 in the track inspection vehicle 1 has a first stabilizer bar end seat 401, a first through hole (not shown) is provided on the first stabilizer bar end seat 401, the first stabilizer bar 40 support 103 is provided with a first connecting hole 104, and the track inspection vehicle 1 includes a first knob 402, the first knob 402 passes through the first through hole and fits in the first connecting hole 104 to connect the first stabilizer bar 40 support 103 with the first stabilizer bar end seat 401.

[0050] like Figure 1 and Figure 7 As shown, the other end of the second stabilizing bar 50 ( Figure 1The rear end of the second stabilizer bar 50 in the track inspection vehicle 1 has a second stabilizer bar end seat 501, a second through hole (not shown) is provided on the second stabilizer bar end seat 501, and a second stabilizer bar support (not shown) is provided with a second connecting hole. The track inspection vehicle 1 includes a second knob 502, and the second knob 502 passes through the second through hole and fits in the second connecting hole to connect the second stabilizer bar support with the second stabilizer bar end seat 501.

[0051] Furthermore, a third retaining spring is disposed on the first knob 402 and the second knob 502 to prevent the first knob 402 and the second knob 502 from falling off.

[0052] In some embodiments, Figure 1 and Figure 5 As shown, the track inspection vehicle 1 also includes a push rod 60, which includes a hand push 601 and a connecting tube 602. The lower end of the hand push 601 extends into the connecting tube 602 and is connected by a threaded member that transversely penetrates the hand push 601 and the connecting tube 602. The upper end surface of the crossbeam 10 is provided with a fixed seat 106, and the fixed seat 106 has a connecting plate 1061 extending upward, and the connecting plate 1061 extends into the connecting tube 602 through the lower tube mouth of the connecting tube 602. The connecting plate 1061 has a limiting hole (not shown) that penetrates the connecting plate 1061 along its thickness direction. The track inspection vehicle 1 also includes a spring pin 1062, and the spring pin 1062 transversely penetrates the tube wall of the connecting tube 602, and the pop-up head 1063 of the spring pin 1062 can extend into and out of the limiting hole.

[0053] Specifically, when the push rod 60 is connected to the cross beam 10, the connecting tube 602 is sleeved on the connecting plate 1061 of the fixed seat 106, and when the spring pin 1062 is horizontally opposite to the limiting hole on the connecting plate 1061, the pop-up head 1063 of the spring pin 1062 will automatically extend into the limiting hole to connect the push rod 60 to the fixed seat 106. It can be understood that when the push rod 60 needs to be disassembled, the spring pin 1062 can be pulled to pull the pop-up head 1063 out of the limiting hole to achieve the separation of the connecting tube 602 and the connecting plate 1061, thereby completing the disassembly of the push rod 60. Therefore, the push rod 60 and the cross beam 10 are conveniently and quickly disassembled by using the pop-up head 1063 of the spring pin 1062 to extend into or out of the limiting hole.

[0054] In some embodiments, Figure 1 , Figure 2 and Figure 6 As shown, the track inspection vehicle 1 further includes a first connecting rod 70 and a second connecting rod (not shown), the first connecting rod 70 and the second connecting rod are respectively arranged on both sides of the cross beam 10 and are symmetrical about the cross beam 10, and the first end of the first connecting rod 70 is connected to one side surface of the cross beam 10 ( Figure 1 The left side of the middle cross beam 10) is detachably connected, and the first end of the second connecting rod is connected to the other side of the cross beam 10 ( Figure 1The right side of the middle cross beam 10) is detachably connected.

[0055] like Figure 6 As shown, the first connecting rod 70 is located on the left side of the beam 10, the front end of the first connecting rod 70 is connected to the left side surface of the beam 10, and the rear end of the first connecting rod 70 is a free end for connecting with other components or equipment. The second connecting rod is located on the right side of the beam 10, the front end of the second connecting rod is connected to the right side surface of the beam 10, and the rear end of the second connecting rod is a free end for connecting with other components or equipment.

[0056] Specifically, Figure 2 As shown, a joint bearing is provided on the left side surface of the cross beam 10, and the front end of the first connecting rod 70 has two spaced-apart retaining plates, the joint bearing is clamped between the two retaining plates, and a cotter pin 105 is provided which passes through the retaining plates and the joint bearing in sequence to connect the joint bearing to the cross beam 10, and the cotter pin 105 can limit the swing of the first connecting rod 70 in the vertical direction.

[0057] Furthermore, a spherical bearing is also provided on the right side surface of the cross beam 10 for connecting with the second connecting rod. The connection method between the spherical bearing and the second connecting rod is the same as the connection method between the first connecting rod 70 and the spherical bearing, which will not be repeated here.

[0058] In some embodiments, Figure 2 and Figure 6 As shown, the first stabilizer bar support 103 includes a first connecting plate 1031 and a first supporting plate 1032, the first connecting plate 1031 is connected to the upper end of the first supporting plate 1032, the first connecting plate 1031 is a horizontal plate and is connected to the first stabilizer bar end seat 401, the first supporting plate 1032 is provided with a first connecting rod clamping seat 1033, the first connecting rod clamping seat 1033 is arranged below the first connecting plate 1031, and the first connecting rod 70 is clamped between the first connecting rod clamping seat 1033 and the first connecting plate 1031. It can be understood that the joint bearing connected to the left side of the crossbeam 10 and the first stabilizer bar support 103 can both be used to support the first connecting rod 70, and the first connecting plate 1031 and the first connecting rod clamping seat 1033 can clamp the first connecting rod 70 to achieve the limitation of the first connecting rod 70.

[0059] Similarly, the second stabilizer bar support (not shown) includes a second connecting plate and a second supporting plate, the second connecting plate is connected to the upper end of the second supporting plate, the second connecting plate is a horizontal plate and is connected to the second stabilizer bar end seat 501, the second supporting plate is provided with a second connecting rod holder, the second connecting rod holder is arranged below the second connecting plate, and the second connecting rod clamp is arranged between the second connecting plate and the second connecting rod holder. Thus, the second connecting plate and the second connecting rod holder can clamp the second connecting rod to limit the second connecting rod, and the second connecting plate and the joint bearing connected to the right side of the cross beam 10 can support the second connecting rod.

[0060] Furthermore, if Figure 8 As shown, the upper end surface of the first connecting rod holder 1033 is an inclined surface extending downwardly in a direction away from the first support plate 1032, and the upper end surface of the second connecting rod holder is an inclined surface extending downwardly in a direction away from the second support plate. Thus, the first connecting rod 70 is suitable for sliding along the inclined surface until it is clamped between the first connecting holder and the first connecting plate 1031, and the second connecting rod is suitable for sliding along the inclined surface until it is clamped between the second connecting holder and the second connecting plate.

[0061] In some embodiments, Figure 1 As shown, the second end ( Figure 1 The left end of the first support arm 20) and the second end of the second support arm 30 ( Figure 1 The distance dimension between the right end of the second support arm 30 is L, then 1500mm≤L≤2500mm. For example, L can be 1800mm, 2000mm or 2200mm. Therefore, by setting L to a reasonable value, the detection accuracy of the track inspection vehicle 1 is guaranteed while the track inspection vehicle 1 has a reasonable structure and is easy to assemble.
