Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] Reference Figure 1-Figure 5 The utility model provides a rail transit inspection machine that is easy to maintain, including: a walking unit 1. The walking unit 1 is used to walk on the track beam, and supports the mounting seat 2 so that the mounting seat 2 drives the detection unit to walk on the track beam.

[0036] The mounting seat 2 is fixed on the walking unit 1, and slide grooves 3 are respectively provided on the two opposite side walls of the mounting seat 2, and the slide grooves 3 include a first groove section 301 and a second groove section 302, the first groove section 301 is located above the second groove section 302, and the first groove section 301 is connected to the second groove section 302 through an inclined groove section 303; the connecting member includes a plate frame 4 that slides with the side wall of the mounting seat 2, an L-shaped frame 5 is passed through the plate frame 4, a detection unit is connected to the horizontal end of the L-shaped frame 5, and the vertical end of the L-shaped frame 5 is slidably matched with the slide groove 3, so that the detection unit can switch between a detection state and a maintenance state; wherein, in the detection state, the vertical end of the L-shaped frame 5 is located in the first groove section 301, and the detection unit is vertically arranged with the walking direction of the walking unit 1, and in the maintenance state, the vertical end of the L-shaped frame 5 is located in the second groove section 302, and the detection unit is horizontally arranged with the walking direction of the walking unit 1.

[0037] Specifically, since the first slot section 301 and the second slot section 302 are located at different heights, when the driving plate frame 4 moves relative to the mounting seat 2, the plate frame 4 drives the L-shaped frame 5 to move, so that the vertical end of the L-shaped frame 5 moves in the slide slot 3. When the vertical end of the L-shaped frame 5 is in the first slot section 301, the state is the detection state, and the detection end of the detection unit is close to the track beam, and the track beam is detected during the movement of the walking unit 1. When the vertical end of the L-shaped frame 5 is in the second slot section 302, the state is the maintenance state, and the detection end of the detection unit is far away from the track beam, which is convenient for disassembly and maintenance of the detection end on the detection unit. At the same time, after the walking unit 1 leaves the track beam, in the maintenance state, the detection end on the detection unit is far away from the ground, reducing the risk of the detection end touching the ground and being damaged.

[0038] A pair of connecting members are provided and are respectively located on both sides of the mounting seat 2 to ensure that two detection units can perform synchronous flaw detection on the two track beams.

[0039] For further optimization, refer to Figure 4 , Figure 5 , and also includes a third slot section 304, which is arranged on a side of the first slot section 301 away from the second slot section 302, the third slot section 304 and the second slot section 302 are located at the same height, and the third slot section 304 is connected to the first slot section 301 through another inclined slot section 303; the vertical end of the L-shaped frame 5 is located in the third slot section 304, and the detection unit is in a storage state.

[0040] Specifically, when the vertical end of the L-shaped frame 5 is located in the third slot section 304, the detection unit is away from the ground and can be stored to protect the detection unit.

[0041] For further optimization, refer to Figure 4 , Figure 5 , and also includes a storage box 6 with a bottom opening, which is fixed on the side wall of the mounting base 2 and is located on a side of the third slot section 304 away from the first slot section 301. In the storage state, the detection unit is located in the storage box 6.

[0042] Specifically, the storage box 6 is fixed on the side wall of the mounting base 2. When the vertical end of the L-shaped frame 5 moves from the first slot section 301 to the third slot section 304, the detection unit rotates and enters the storage box 6 through the bottom opening of the storage box 6 for storage.

[0043] For further optimization, refer to Figure 5 A pair of upper and lower slide rails 7 are fixed to the side walls of the mounting seat 2, the plate frame 4 includes a movable plate 401, the L-shaped frame 5 is passed through and rotated on the movable plate 401, two pairs of limit plates 402 are fixed on the side of the movable plate 401 close to the slide rail 7, the slide rail 7 is located between the pair of limit plates 402, and the movable plate 401 is limitedly slidably connected with the slide rail 7 through the limit plates 402.

[0044] Among them, the two pairs of limit plates 402 correspond to the two slide rails 7 respectively, and each pair of limit plates 402 has two limit plates 402. The two limit plates 402 cooperate with the slide rails 7 so that the movable plate 401 can only move along the extension direction of the slide rails 7 to drive the L-shaped frame 5 to move in the slide groove 3.

[0045] Furthermore, a limiting groove may be provided on the slide rail 7 , and a protrusion matching the limiting groove may be fixed on the limiting plate 402 , so as to achieve a limiting connection between the slide rail 7 and the limiting plate 402 .

[0046] For further optimization, refer to Figure 5 , and also includes a fixing member that is detachably connected to the plate frame 4 so that the plate frame 4 can be switched between a fixed state and a sliding state.

[0047] For further optimization, refer to Figure 5The fixing member includes a latch 8, and a plurality of insertion holes 9 are provided on the upper slide rail 7. The end of the latch 8 passes through one of the insertion holes 9 and extends into the upper limiting plate 402 to fix the movable plate 401 to the slide rail 7.

[0048] Specifically, when in the detection state, maintenance state, and storage state, in order to ensure that the movable plate 401 is fixed relative to the mounting base 2 in the above states, a socket 9 is opened on the slide rail 7 corresponding to the first slot section 301, the second slot section 302, and the third slot section 304, and at the same time, a through hole is opened in the upper limit plate 402, and the pin 8 extends into the socket 9 through the through hole, thereby fixing the movable plate 401 relative to the slide rail 7.

[0049] For further optimization, refer to Figure 5 The L-shaped frame 5 includes: a first rod body 501, which passes through the plate frame 4, an extension plate 502 is fixed to one end of the first rod body 501, and a sliding column 504 is fixed to the end of the extension plate 502 away from the first rod body 501, and the sliding column 504 is slidably matched with the slide groove 3; an extension rod 503 is fixed to the other end of the first rod body 501, the extension plate 502 and the extension rod 503 are in opposite directions, and the detection unit is fixed at the end of the extension rod 503.

[0050] Specifically, when the slide post 504 moves in the slide slot 3, under the structural restriction of the slide slot 3, the first rod body 501 rotates and drives the extension rod 503 to rotate, and the rotation of the extension rod 503 drives the detection unit to rotate to change the relative position of the detection unit and the mounting base 2.

[0051] For further optimization, refer to Figure 2 , Figure 3 The detection unit includes: a mounting base 10 fixed on the L-shaped frame 5; a camera 11 detachably connected to the mounting base 10; and an ultrasonic flaw detector 12 detachably connected to the mounting base 10.

[0052] Specifically, the mounting base 10 may be a plate structure, and the camera 11 and the ultrasonic flaw detector 12 may be fixed to the mounting base 10 by bolts. The existing camera 11 and the ultrasonic flaw detector 12 are usually fixed to the end surface of the plate body close to the track beam by bolts. When disassembling, since the bolts are located at the bottom of the plate body, it is not easy to disassemble. However, the mounting base 10 is mounted on the rotatable extension rod 503. When disassembling, only the extension rod 503 needs to be rotated to expose the bottom of the plate body, so that the camera 11 and the ultrasonic flaw detector 12 can be easily disassembled.

[0053] For further optimization, refer to Figure 1 The traveling unit 1 is a rail vehicle base, and the rail vehicle base is configured to move forward or backward along the rail beam.

[0056] Specifically, during actual inspection, two operators inspect and process the track beam, one of whom is the driver, who controls the movement of the rail vehicle through the controller 14, and the other is the inspector, who connects the display to the inspection unit and places the display on the platform 15.

[0057] During the actual inspection, the driver is located on the seat 13 in the direction of travel of the rail vehicle, and the inspector is located on the seat 13 away from the direction of travel of the rail vehicle, and the driver and the inspector are staggered to facilitate the two to observe the road conditions in front and behind.

[0058] Among them, two controllers 14 are provided, one controller 14 is used to control the forward movement of the rail vehicle base, and the other controller 14 is used to control the reverse movement of the rail vehicle base. Therefore, when the direction of travel of the rail vehicle changes, the driver can switch positions with the inspection personnel so that the driver always faces the direction of travel of the rail vehicle.

[0059] The above are only preferred specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
