[0033] like Figure 1 As shown, an embodiment of the utility model provides a rail trolley, which moves along a circular track 400. The rail trolley includes a trolley frame 100, wheels installed on the trolley frame 100, and a clamping device.

[0034] It is understandable that in the conventional technology, in order to install the rail trolley on the surround track 400, the rail trolley is inserted from one end of the surround track 400, which is inconvenient to operate and has low efficiency. For this reason, the utility model provides a rail trolley, which avoids the traditional insertion method and instead provides a clamping force for the clamping wheel 220 through a clamping device, and the rail trolley can be clamped on the surround track 400 through cooperation with the driving wheel 210, so that the operation process is simpler and more efficient.

[0035] In some embodiments of the present invention, the wheel includes a driving wheel 210 and a pressure wheel 220 , wherein the driving wheel 210 is disposed on one side of the orbital track 400 , and the pressure wheel 220 is disposed on the other side of the orbital track 400 .

[0036] Optionally, one clamping wheel 220 is provided, and two driving wheels 210 are provided, and the clamping wheel 220 and the driving wheel 210 are arranged in a triangle.

[0037] It can be understood that the utility model provides a clamping force for the clamping wheel through the clamping device, and the cooperation between the clamping wheel 220, the driving wheel 210 and the clamping device enables the rail trolley to be clamped on the surrounding rail 400. Furthermore, a triangular layout is formed by two driving wheels 210 and one clamping wheel 220, and the structure is more stable. At the same time, the clamping wheel 220 on the other side is set as one, so that the rail trolley can adapt to a smaller diameter track, thereby improving the scope of application of the rail trolley.

[0038] It should be noted that the present invention does not limit the number of the clamping wheel 220 to one. During the use of the reagent, the number of the clamping wheels 220 and the driving wheel 210 can be adjusted according to the diameter of the orbital track 400, and the orbital track 400 can be a circular track or a non-circular track.

[0039] In some embodiments of the utility model, the clamping device includes a first swing arm 310, a second swing arm 320, a first elastic component and a second elastic component; the first swing arm 310 and the second swing arm 320 are elastically connected by the first elastic component, and the distance between the first swing arm 310 and the second swing arm 320 can be adjusted by the first elastic component; one end of the first swing arm 310 is rotatably mounted on the trolley frame 100, and the other end is mounted on the rotating shaft of the clamping wheel 220, one end of the second swing arm 320 is mounted on the rotating shaft of the clamping wheel 220, and the other end extends in a direction away from the first swing arm 310 and can be elastically engaged with the second elastic component.

[0040] It can be understood that the first swing arm 310 of the utility model is rotatably connected to the trolley frame 100 via the rotating shaft 312, so that the relative position between the first swing arm 310 and the trolley frame 100 is adjustable, and the relative position of the first swing arm 310 and the second swing arm 320 can be adjusted by adjusting the elastic force of the first elastic component, thereby realizing the adjustment of the clamping force between the rail trolley and the surround rail 400; in addition, the movable end of the second swing arm 320 is elastically fixed by the second elastic component, so that the clamping wheel 220 always clamps the surround rail 400, thereby realizing the rapid installation and separation of the rail trolley and the surround rail 400.

[0041] In some embodiments of the utility model, the first elastic component includes an elastic member 331, a connecting rod 332, a first support member 333 and a second support member 334; the first support member 333 and the second support member 334 are respectively arranged on the side of the first swing arm 310 and the second swing arm 320 facing the center of the orbital track 400, the elastic member 331 passes through the connecting rod 332, and the two ends of the connecting rod 332 are respectively connected to the first support member 333 and the second support member 334, the length of the connecting rod 332 located between the first support member 333 and the second support member 334 is adjustable so that the compression force of the elastic member 331 can be adjusted, and the first support member 333 or the second support member 334 is provided with an oblong hole.

[0042] Optionally, in order to realize the connection between the first swing arm 310 and the second swing arm 320 and the rotating shaft of the clamping wheel 220, two first connecting parts 311 are provided at one end of the first swing arm 310 close to the clamping wheel 220, respectively fixed to the two ends of the rotating shaft of the clamping wheel 220. Similarly, two second connecting parts 321 are provided at one end of the second swing arm 320 close to the clamping wheel 220, respectively fixed to the two ends of the rotating shaft of the clamping wheel 220, so as to adjust the relative position of the second swing arm 320 and the trolley frame 100 and the first swing arm 310 through the first elastic component according to actual conditions, so as to realize the adjustment of the clamping force.

[0043] Optionally, the first support member 333 and the second support member 334 are both angle support frames, and the extension direction of the oblong hole is perpendicular to the direction of the rotating shaft 312, so as to adjust the relative position between the first swing arm 310 and the second swing arm 320, and the relative position between the first swing arm 310, the second swing arm 320 and the trolley frame 100, so as to facilitate the installation and disassembly of the clamping device.

[0044] It can be understood that the elastic member 331 can be a spring, and the connecting rod 332 can be a bolt or other rod. When the connecting rod 332 is a bolt, the bolt passes through the first support member 333, the spring, and the second support member 334 in sequence and is fixed by a nut. When the first swing arm 310 and the second swing arm 320 rotate relative to each other, the support member compression spring moves along the bolt. By adjusting the distance between the bolt and the nut or replacing springs with different lengths / elastic forces to adjust the elastic force of the spring, the clamping force can be adjusted.

[0045] In some embodiments of the present invention, the second elastic component includes an elastic latch structure and a baffle 340 ; the baffle 340 is installed on the side of the second swing arm 320 facing the trolley frame 100 , and the elastic latch structure is installed on the trolley frame 100 and elastically engaged with the baffle 340 .

[0046] Optionally, the elastic latch structure includes an operating part 351 and a spring pin 352 elastically connected to the operating part 351, wherein the operating part 351 can be a button or a handle, and the trolley frame 100 is provided with a mounting hole adapted to the spring pin 352 on the side facing the surround track 400, and the mounting hole is used for the pop-up and retraction of the spring pin 352. When the spring pin 352 is in the pop-up state, the blocking piece 340 is engaged with the spring pin 352.

[0047] It can be understood that when the track trolley needs to be separated from the surround track 400, the spring pin 352 is retracted into the installation hole by controlling the operating part 351, the blocking force of the spring pin 352 on the baffle 340 disappears, the first swing arm 310 and the second swing arm 320 are rotated open, and the track trolley can be quickly removed from the track; and when the track trolley needs to be installed on the surround track 400, the clamping wheel is pressed into the side of the surround track 400 toward its center, and the spring pin 352 is popped out of the installation hole by controlling the operating part 351, and the spring pin 352 applies a blocking force to the baffle 340, and then the first swing arm 310 and the second swing arm 320 are fixed in the working position, so that the clamping wheel 220 always clamps the side of the surround track 400 toward its center, thereby achieving quick installation.

[0048] In some embodiments of the present invention, a moving groove 410 is provided on one side of the surrounding track 400 toward the center thereof, and the pressing wheel 220 is drum-shaped and matches the moving groove 410 .

[0049] It can be understood that the clamping wheel 220 and the movable groove 410 of the surrounding rail 400 form an embedded structure, which can make the clamping wheel and the surrounding rail 400 fit more closely, thereby making the operation process more stable.

[0050] In addition, the utility model also discloses a detection device, including the rail trolley described in any one of the above items, so as to realize the intelligent operation of the detection instrument by carrying the detection instrument on the rail trolley.

[0051] In summary, the operation of installing or separating the track trolley and the surround track of the utility model is simpler and more efficient, and the clamping force between the track trolley and the surround track can be adjusted to achieve rapid installation and separation of the track trolley and the surround track.

[0052] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
