[0018] like Figure 1-3As shown, this utility model provides a rail distance measuring vehicle to solve the problems of low efficiency and poor accuracy of existing rail spacing measurement methods, as well as the complex structure and poor adaptability of existing automated measuring equipment. The distance measuring vehicle includes a main body 1, a laser rangefinder 6, and a drive unit. The main body 1 is a square box made of stainless steel plate. A strip-shaped notch 4 corresponding to the rail is provided below the main body 1. The width of the strip-shaped notch 4 is larger than the rail track 17, so that the main body 1 can straddle one of the rail tracks 17. The laser rangefinder 6 is set on the lower edge of the side wall of the main body 1. The laser rangefinder 6 extends horizontally in a direction perpendicular to the main body 1, pointing to the other rail track 17, so as to measure the rail spacing. As the main body 1 moves, this application can continuously measure the rail spacing, improving the measurement accuracy. Two drive units are respectively set at both ends of the strip-shaped notch 4, so as to drive the main body 1. The drive body 1 can slide along the extension direction of the track 17. As the body 1 moves, the distance between the two tracks 17 is continuously and completely measured. The drive device includes a main frame 7, a drive screw 13, a drive wheel 12, and a clamping wheel 11. The strip-shaped notch 4 only cuts the bottom and two ends of the body 1, so that the drive device can be installed laterally inside the body 1. Specifically, the two ends of the main frame 7 are fixed to the inner walls of the two sides of the body 1 by bolts, so that the drive wheel 12 and the clamping wheel 11 are located on both sides of the strip-shaped notch 4, so that the drive wheel 12 has sufficient friction to drive. The drive wheel 12 is rotatably connected to one end of the main frame 7. The drive motor 14 corresponding to the drive wheel 12 is provided in the main frame 7. The clamping wheel 11 is slidably mounted on the other end of the main frame 7 through the slider 9 and is threadedly driven by the drive screw 13, so as to stably clamp the track 17 and ensure the stability of operation.
[0019] In this embodiment, the side wall of the main body 1 is provided with a through hole corresponding to the drive screw 13, so that the rotating handle 10 can be inserted to drive the drive screw 13.
[0020] The main frame 7 is a square groove with end plates at both ends. Its length is adapted to the width of the inner cavity of the main body 1. The end plates are provided with screw holes, so that the main frame 7 can be fixed by threaded assembly. A partition is provided in the middle of the main body 1 above the corresponding drive device, so that the internally integrated wireless transmission module, control module and power supply form an independent wall to prevent rain or dust from entering.
[0021] The main body 1 has a battery slot at the top corresponding to the power source, which is a lithium battery 2, so that the lithium battery 2 can be replaced quickly.
[0022] After the end plate extends upward, it connects to the top plate 8. The length of the top plate 8 is adapted to the main frame 7. The slider 9 is a square sleeve adapted to the main frame 7. The gap between the top plate 8 and the main frame 7 is adapted to the thickness of the square sleeve. A fixing plate 16 is provided inside the square sleeve and extends into the main frame 7. The shape of the fixing plate 16 is adapted to the cross section of the inner cavity of the main frame 7. One end of the drive screw 13 is rotatably connected to the end plate of the main frame 7, and the other end is threadedly connected to the fixing plate 16, thereby realizing the threaded drive of the slider 9. In this embodiment, a hexagonal groove is provided at the end of the drive screw 13, and the main shaft of the rotating handle 10 is provided with a corresponding hexagonal bit.
[0023] The clamping wheel 11 is connected to the lower surface of the square sleeve by a rotating connection structure. In this embodiment, the square sleeve, the main frame 7 and the top plate 8 are all steel plates, thus having high rigidity.
[0024] The drive motor 14 is correspondingly installed in the inner cavity of the main frame 7, and the main shaft of the drive motor 14 passes through the bottom plate of the main frame 7 and is connected to the drive wheel 12.
[0025] In an optional embodiment, the laser rangefinder 6, wireless transmission module, and drive motor 14 on the main body 1 are correspondingly connected to the control module, which can be a CPU, microcontroller, or PLC. The wireless transmission module can transmit measurement data to the control terminal. An antenna 3 is provided on the main body 1 to connect to the wireless transmission module. The control terminal can be a mobile phone or tablet. An encoder 15 is provided on the main shaft of the drive motor 14 to detect the travel distance in combination with the circumference of the drive shaft, and then associate the detection data with the corresponding position.
[0026] In addition, the control terminal can send control signals to the control module, and the control body 1 can move or return along a preset trajectory.
[0027] In this embodiment, a positioning module is also integrated on the main body 1, which facilitates the positioning of the main body 1.
[0028] In addition, the drive wheel 12 and clamping wheel 11 are made of rubber, and their outer walls are adapted to the shape of the side wall of the track 17, thereby increasing the friction with the track 17 and ensuring the effectiveness of the drive. Furthermore, in order to reduce the friction between the main body 1 and the track 17, the strip-shaped notch 4 is provided with a roller 5 corresponding to the track 17, so that the main body 1 can slide along the track 17 through the roller 5. The drive wheel 12 and clamping wheel 11 are made of rubber, and their outer walls are adapted to the shape of the side wall of the track 17. In this way, the shape of the drive wheel 12 and clamping wheel 11 and the roller 5 can be used to limit the track 17 in the longitudinal direction.
[0029] The method of using the distance measuring vehicle provided in this application is as follows: The rail ranging vehicle is placed on the rail, so that the main body 1 straddles one of the rails 17 through the strip-shaped notch 4, and the clamping wheel 11 and the drive wheel 12 are clamped on both sides of the rail 17 by adjusting the drive screw 13.
[0030] Turn on the power and send a command to the control module through an external device to start the drive motor 14, so that the ranging vehicle moves along the track 17.
[0031] During the movement of the ranging vehicle, the laser rangefinder 6 measures the distance to another track 17 in real time and transmits the measurement data to the control module.
[0032] The control module transmits the measurement data to the control terminal in real time via a wireless transmission module, allowing staff to view and analyze the measurement data on the control terminal.
[0033] After the measurement is completed, a stop command is sent to the control module through the control terminal. After the distance measuring vehicle returns, it is removed from the rail. A handle is also provided on the main body 1 for easy picking and putting.
[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be within the scope of protection of the pending claims of the present utility model.
