Description

Technical Field

[0001] The utility model relates to the technical field of track detection vehicles, in particular to a new type of track detection vehicle. Background Art

[0002] With the rapid development of rail transit, the demand for railway track inspection is also increasing. As an important equipment for maintaining track safety and ensuring operation quality, the performance and efficiency of the track inspection vehicle have a significant impact on the safe operation of the entire rail transit system. The main functions of the track inspection vehicle include detecting track geometry parameters, track wear, track smoothness, and the status of other track facilities. However, the existing track inspection vehicles still have some shortcomings, as follows:

[0003] Complex track approach operation: Traditional track inspection vehicles usually need to enter the track through a specific track starting point, or lift the inspection vehicle above the track with the help of manual labor and auxiliary equipment. This operation method is complicated and time-consuming, and it is difficult to get on and off the track at any position along the track, which is not flexible enough.

[0004] Low efficiency of track switching: After completing the inspection task, the traditional inspection vehicle needs to return to the starting point of the track before driving off the track, or rely on complex auxiliary tools to switch the track up and down. This method leads to low inspection efficiency and cannot meet the flexible needs of modern track inspection. Utility Model Content

[0059] See also Figure 1-7 A new type of track inspection vehicle comprises a frame 1, a detection box 2 placed at the top center of the frame 1, and a track travel assembly 6 installed at the front and rear ends of the bottom of the frame 1, characterized in that: an upper and lower track mechanism 7 is arranged at the bottom center of the frame 1, two side positioning clamps 3 for clamping the left and right box walls of the detection box 2 are arranged at the top of the frame 1, and a clamping drive mechanism 4 for synchronously driving the side positioning clamps 3 on both sides is arranged inside the frame 1;

[0060] The upper and lower track mechanism 7 specifically includes the following structures:

[0061] Two running tracks 71 perpendicular to the track direction and distributed in parallel;

[0062] A connecting frame 72 connecting the traveling tracks 71 on both sides;

[0063] A top delivery mechanism 73 distributed between the connecting frame 72 and the bottom of the frame 1;

[0064] Corresponding to the guide posts 74 installed at both ends of the traveling crawler 71, the guide posts 74 on both sides are slidably connected to the inside of the vehicle frame 1;

[0065] The track inspection vehicle of the mechanism provides the ability to go up and down the track by itself, without the need for manual labor or other tools to move the inspection vehicle to the top of the track, and the inspection vehicle can be operated up and down at any position along the track, which is more practical. The design of the running track 71 enables the vehicle to travel directly from the side of the track to the top of the track, which is convenient for the subsequent positioning operation of the track running component 6.

[0066] The clamping drive mechanism 4 specifically includes the following structures:

[0067] A first dual-shaft reduction motor 41 distributed at the top center of the frame 1;

[0068] A first driving screw 42 connected to the left and right output ends of the first dual-axis reduction motor 41;

[0069] The first screw sleeves 43 are respectively threadedly sleeved on the first driving screws 42 on both sides, and the top tube walls of the first screw sleeves 43 on both sides are respectively fixedly connected to the bottom centers of the side positioning clamps 3 on both sides;

[0070] The key to the design of this part is to provide a stable and precise driving force, so that the side positioning clamps 3 on both sides can move synchronously, ensuring that the detection chassis 2 maintains the correct position during operation, and at the same time enables the detection vehicle to place and position different detection equipment, with wider applicability.

[0071] The track travel assembly 6 comprises:

[0072] The track-running wheels 62 in the assembly are specially designed to fit the track precisely, ensuring that the vehicle runs smoothly along the track. The bracket 61 is designed to mount the wheels.

[0073] The top delivery mechanism specifically includes the following structures:

[0074] Two installation slides 732 symmetrically and parallelly distributed on the top surface of the connecting frame 72;

[0075] A plurality of herringbone articulated frames 731 supported between the top of the mounting slides 732 on both sides and the bottom of the frame 1;

[0076] An angle adjustment mechanism 733 distributed inside the connecting frame 72 drives the installation slides 732 on both sides to move relative to each other, thereby adjusting the top angle of the herringbone hinge frame 731;

[0077] Corresponding to the top delivery guide assembly 734 distributed on the front and rear sides of the angle adjustment mechanism 733;

[0078] Among them, the angle adjustment mechanism 733 inside the jacking mechanism can adjust the angle of the top of the herringbone articulated frame 731. The smaller the angle, the farther the traveling tracks 71 and the connecting frame 72 on both sides are from the bottom of the frame 1, until the traveling tracks 71 on both sides are jacked up to fit the track and lift up the track traveling wheels 62, at this time, the up and down track operations can be performed.

[0079] The angle adjustment mechanism 733 specifically includes the following structures:

[0080] A second screw sleeve 7333 corresponding to the bottom center of the mounting slide 732 on both sides;

[0081] The second driving screw rod 7332 correspondingly threadedly penetrates the second screw rod sleeves 7333 on both sides;

[0082] The second dual-axis reduction motor 7331 is located at the center of the second driving screw rods 7332 on both sides and is respectively connected to one end of the inner side of the second driving screw rods 7332 on both sides.

[0083] The top delivery guide assembly 734 specifically includes the following structures:

[0084] A second guide rod 7341 disposed laterally;

[0085] Corresponding to the second guide sleeves 7342 slidably sleeved on both ends of the second guide rod 7341 , the top tube walls of the second guide sleeves 7342 on both sides are respectively connected to the same side ends of the bottoms of the mounting slides 732 on both sides.

[0086] The frame 1 is provided with clamping guide components 5 on both the front and rear sides of the clamping drive mechanism 4 for cooperating with the side positioning clamps 3 on both sides to perform clamping movement.

[0087] The clamping guide assembly 5 specifically includes the following structure:

[0088] A first guide rod 51 disposed laterally;

[0089] The first guide sleeves 52 are slidably sleeved on both ends of the first guide rod 51, and the top tube walls of the first guide sleeves 52 on both sides are respectively connected to the same side ends of the bottoms of the side positioning clamps 3 on both sides;

[0090] The assembly realizes the smooth and linear guided movement of the side positioning clamp plate 3 through the coordinated use of the guide rod 51 and the guide sleeve 52 .

[0091] How it works

[0092] The detection chassis 2 is clamped in the side positioning clamping plate 3 on the top of the frame 1 to ensure the stability of the detection equipment during the movement.

[0093] Approaching the track and positioning:

[0094] The jacking mechanism 73 starts to work, and adjusts the angle of the herringbone articulated frame 731 through the internal angle adjustment mechanism 733, so that the running tracks 71 on both sides are pushed downward until the track running wheels 62 are lifted up.

[0095] The inspection vehicle approaches the track via the running track 71. The design of the running track 71 allows the inspection vehicle to drive directly from the side of the track to the top of the track.

[0096] At this time, the position of the entire inspection vehicle is adjusted so that the track-driving wheels 62 at the front and rear ends are directly above the tracks on both sides, and then the top-feeding mechanism 73 is reversely started to retract the driving tracks 71 on both sides, so that the track-driving wheels 62 at the front and rear ends are just stuck above the tracks on both sides.

[0097] Detection operation:

[0098] The detection vehicle moves along the track to perform real-time track detection. The detection chassis 2 may contain a variety of sensors and detection equipment to collect track status data.

[0099] Down track and back:

[0100] After completing the inspection task, the angle is adjusted by the push-up mechanism 73 so that the traveling track 71 contacts the track again, and the vehicle can drive out of the track from any place.
