[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0031] In some embodiments, please refer to the accompanying drawings. Figures 1-5 A monorail flaw detection vehicle cooperative operation device includes a monorail flaw detection vehicle body 1, a bidirectional anti-detachment mechanism 2, and an adaptive connection mechanism 3; mounting plates 13 are symmetrically fixedly installed on the front and rear sides of the lower end of the monorail flaw detection vehicle body 1; drive wheels 11 that are rolled and connected to the upper end of the track are rotatably connected to the inner walls of the left and right sides of the mounting plates 13; a drive motor 12 is fixedly installed on the left end of the mounting plate 13; the output end of the drive motor 12 is fixedly connected to the drive wheel 11; connecting plates 14 are symmetrically fixedly installed on the front and rear sides of the two monorail flaw detection vehicle bodies 1 that are close to each other.

[0032] A two-way anti-detachment mechanism 2 is installed at the lower middle part of the monorail flaw detection vehicle body 1 to prevent the monorail flaw detection vehicle body 1 from detaching from the track.

[0033] like Figure 2 As shown, the bidirectional anti-detachment mechanism 2 includes a drive assembly and a movable assembly; the drive assembly is installed at the lower middle part of the monorail flaw detection vehicle body 1; movable assemblies are symmetrically connected to the left and right sides of the drive assembly;

[0034] The two monorail flaw detection vehicle bodies 1 on the left and right are connected by an adaptive connection mechanism 3;

[0035] The adaptive connection mechanism 3 consists of two connecting rods 31, a U-shaped fixing frame 38, a fixing cylinder 33, a vehicle body fixing component, and a connection fixing component;

[0036] The two connecting rods 31 are hinged in the middle, so that the two connecting rods 31 form a rotatable "X" shape structure;

[0037] Furthermore, both ends of each connecting rod 31 are connected to a fixed cylinder 33 via a connecting and fixing assembly;

[0038] The lower end of the fixed cylinder 33 is rotatably connected to the upper end of the U-shaped fixed bracket 38;

[0039] The lower end of the U-shaped mounting bracket 38 is equipped with a vehicle body fixing component;

[0040] The vehicle body fixing assembly is used to fix the U-shaped fixing bracket 38 to the connecting plate 14;

[0041] The height of the upper end of the U-shaped fixing bracket 38 installed on the connecting plate 14 at the front of the left monorail flaw detection vehicle body 1 and the connecting plate 14 at the rear of the right monorail flaw detection vehicle body 1 is lower than the height of the upper end of the U-shaped fixing bracket 38 installed on the connecting plate 14 at the rear of the left monorail flaw detection vehicle body 1 and the connecting plate 14 at the front of the right monorail flaw detection vehicle body 1.

[0042] In this utility model, two monorail flaw detection vehicle bodies 1 are placed above the track, at which time the drive wheel 11 contacts the upper end of the track; then the drive assembly works to drive the two movable components to move simultaneously toward the track until the movable components contact and abut against the rail web to prevent the monorail flaw detection vehicle body 1 from separating from the track.

[0043] Then, multiple U-shaped fixing brackets 38 are inserted into the connecting plates 14 installed at one end of the two monorail flaw detection vehicle bodies 1; and the U-shaped fixing brackets 38 are fixed to the connecting plates 14 by the vehicle body fixing components;

[0044] Then pull the two connecting rods 31 outward to unfold them, and rotate the fixing cylinder 33 so that one end of the upper connecting rod 31 is aligned with the rear fixing cylinder 33 installed on the left monorail flaw detection vehicle body 1; and the other end of the upper connecting rod 31 is aligned with the front fixing cylinder 33 installed on the right monorail flaw detection vehicle body 1.

[0045] One end of the lower connecting rod 31 is aligned with the front fixing cylinder 33 installed on the left monorail flaw detection vehicle body 1, and the other end of the lower connecting rod 31 is aligned with the rear fixing cylinder 33 installed on the right monorail flaw detection vehicle body 1.

[0046] Finally, the two ends of the connecting rod 31 are fixed to the corresponding fixing cylinder 33 by connecting and fixing components; at this time, the two cross-hinged connecting rods 31 connect the monorail flaw detection vehicle bodies 1 on the left and right sides; then the drive motors 12 on the two monorail flaw detection vehicle bodies 1 work to drive the drive wheels 11 to rotate, so that the drive wheels 11 move forward along the upper end of the track; thus, the parallel track can be used for coordinated flaw detection operation.

[0047] The cooperation between the drive wheel 11 and the drive motor 12 eliminates the need for operators to apply significant thrust to the monorail flaw detection vehicle body 1, reducing the extra workload for operators when controlling the monorail flaw detection vehicle body 1 to inspect the track. The cooperation between the drive assembly and the moving assembly prevents the monorail flaw detection vehicle body 1 from detaching from the track, ensuring smooth flaw detection operations. Furthermore, the two connecting rods 31 connect the two monorail flaw detection vehicle bodies 1 to each other, facilitating coordinated flaw detection operations on parallel tracks and improving the stability of the two monorail flaw detection vehicle bodies 1 when cornering. The cooperation between the vehicle body fixing assembly and the connecting fixing assembly reduces the difficulty for operators in coordinating the docking of the two monorail flaw detection vehicle bodies 1.

[0048] like Figure 2 and Figure 5 As shown, the drive assembly includes a U-shaped plate 21, a bidirectional lead screw 22, a guide rail 23, and a servo motor 27. The U-shaped plate 21 is fixedly installed at the lower middle part of the monorail flaw detection vehicle body 1. The left and right ends of the bidirectional lead screw 22 are rotatably connected to the inner walls of the left and right sides of the U-shaped plate 21. The guide rail 23 is fixedly installed on the inner top of the U-shaped plate 21. The bidirectional lead screw 22 and the guide rail 23 are connected to the movable component. The servo motor 27 is fixedly installed at the left end of the U-shaped plate 21. The output end of the servo motor 27 is fixedly connected to the bidirectional lead screw 22.

[0049] like Figure 2 and Figure 5 As shown, the movable component includes a moving block 24, an inner folding plate 25, and a guide wheel 26; the moving blocks 24 are symmetrically and slidably connected to the left and right sides of the guide rail 23; the moving blocks 24 are threadedly connected to the bidirectional lead screw 22; the lower end of the moving block 24 is fixedly installed with an inner folding plate 25; the two inner folding plates 25 are rotatably installed with a guide wheel 26 that is rolled and connected to the rail web at one end that is close to each other;

[0050] like Figure 3 As shown, the vehicle body fixing assembly includes a clamping bolt 310; a threaded hole 39 is provided at the right end of the U-shaped fixing bracket 38; the clamping bolt 310 is threadedly connected to the threaded hole 39;

[0051] like Figure 3 and Figure 4 As shown, the connecting and fixing assembly includes a fixing rod 32, a locking pin 36, and a return spring 37; both ends of the connecting rod 31 are fixedly mounted with fixing rods 32; the fixing cylinder 33 has a slot 34 for engaging with the fixing rod 32; both the fixing rod 32 and the fixing cylinder 33 have locking pin holes 35 for engaging with the locking pin 36; the locking pin 36 and the locking pin hole 35 on the fixing cylinder 33 are in a limited sliding connection; one end of the return spring 37 is fixedly connected to the fixing cylinder 33; the other end of the return spring 37 is fixedly connected to the locking pin 36.

[0052] The upper end of the locking pin 36 is provided with an inclined surface that cooperates with the fixing rod 32;

[0053] In this utility model, two monorail flaw detection vehicle bodies 1 are placed above the track, at which time the drive wheel 11 contacts the upper end of the track; then the servo motor 27 works to drive the bidirectional lead screw 22 to rotate, the bidirectional lead screw 22 rotates to drive the two moving blocks 24 to move inward along the guide rail 23 at the same time, and the inner folding plate 25 moves inward with the moving blocks 24 until the guide wheels 26 installed on the two inner folding plates 25 contact and abut against the rail web;

[0054] Then, insert the U-shaped fixing bracket 38 onto the connecting plate 14 installed at one end of the two monorail flaw detection vehicle bodies 1; and rotate the clamping bolt 310 so that the clamping bolt 310 moves along the threaded hole 39 toward the connecting plate 14 until the threaded hole 39 is pressed against the connecting plate 14, at which point the fixing of the U-shaped fixing bracket 38 and the connecting plate 14 is completed.

[0055] Pull the two connecting rods 31 outward to unfold them, and rotate the fixing cylinder 33 so that one end of the upper connecting rod 31 is aligned with the rear fixing cylinder 33 installed on the left monorail flaw detection vehicle body 1; and the other end of the upper connecting rod 31 is aligned with the front fixing cylinder 33 installed on the right monorail flaw detection vehicle body 1.

[0056] One end of the lower connecting rod 31 is aligned with the front fixing cylinder 33 installed on the left monorail flaw detection vehicle body 1, and the other end of the lower connecting rod 31 is aligned with the rear fixing cylinder 33 installed on the right monorail flaw detection vehicle body 1.

[0057] Then press down on the connecting rod 31; causing the connecting rod 31 to move the fixing rod 32 downwards together. When the lower end of the fixing rod 32 moves into the slot 34 and contacts the upper inclined surface of the locking pin 36 in the fixing cylinder 33, the fixing rod 32 will squeeze the locking pin 36, causing the locking pin 36 to move outwards along the locking pin hole 35 in the fixing cylinder 33. During the movement, the return spring 37 will also be compressed until the locking pin hole 35 in the fixing rod 32 and the locking pin in the fixing cylinder 33 are aligned. Once the hole 35 is aligned, the return spring 37 will return to its original position, causing the locking pin 36 to return inward until the locking pin 36 is inserted into the locking pin hole 35 on the fixed rod 32, thus completing the fixation of the fixed rod 32 and the fixed cylinder 33. At this time, the two cross-hinged connecting rods 31 connect the monorail flaw detection vehicle bodies 1 on the left and right sides. Subsequently, the drive motors 12 on the two monorail flaw detection vehicle bodies 1 work to drive the drive wheels 11 to rotate, causing the drive wheels 11 to move forward along the upper end of the track. This allows for coordinated flaw detection operations on the parallel tracks.

[0058] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
