Description
Technical Field
[0001] The utility model relates to the technical field of railway maintenance, in particular to a railway contact network maintenance engineering vehicle. Background Art
[0002] The railway contact network maintenance engineering vehicle is a 3D holographic imaging intelligent detection vehicle for the geometric performance of the contact network. It is suitable for operations in various outdoor environments. It can perform three-dimensional scanning and reconstruction of the contact network, measure parameters such as pull-out values in real time, identify anomalies and issue alarms. It consists of multiple modules and can perform high-precision detection in full daylight. It is fully automatic electric drive with a maximum speed of 5km / h. It has high collection efficiency and low error, is portable and foldable, and has multiple functions. The detection data can be transmitted wirelessly to a tablet, and the alarm position can be accurately located, providing accurate data support for contact network maintenance.
[0003] Railway contact network maintenance engineering vehicles need to be connected to the track through a connecting arm and move along the track with the help of the moving device on the connecting arm. Most of the existing connecting arms are foldable. The original intention of the design was to reduce the space occupied in the non-operating state for storage and transportation, but during operation, they need to be unfolded and then fixed to the track. However, their unfolding and fixation rely on multiple sets of hinges, bolts or manual locking structures. The operation steps are cumbersome and require manual adjustment of the positioning multiple times. For example, the folding joints must be unlocked one by one when unfolding, and multiple fixing points must be tightened with tools after unfolding. After the operation is completed, folding and storage also require repeated tedious disassembly and reset steps. This not only prolongs the preparation and finishing time before and after maintenance and reduces the overall maintenance efficiency, but may also cause the connecting arm to be unreliably fixed due to manual operation errors, causing shaking when the engineering vehicle is moving, affecting the detection accuracy, and even posing a safety hazard of connection detachment.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0022] See also Figures 1 to 6When the cam 5 is in the closed position, the cam 5 is in the closed position, and the cam 5 is in the closed position, so that the cam 5 can rotate in the closed position, and the cam 5 can rotate in the closed position, and the cam 5 can rotate in the closed position, and the cam 5 can rotate in the closed position, and the cam 5 can rotate in the closed position, and the cam 5 can rotate in the closed position, and the cam 5 can rotate in the closed position, and the cam 5 can rotate in the closed position, and the cam 5 can rotate in the closed position, and the cam 5 can rotate in the closed position, and the cam 5 can rotate in the closed position, and the cam 5 can rotate in the closed position, and the cam 5 can rotate in the closed position, and the cam 5 can rotate in the closed position, The slide bar 6 slides in the rotating groove 8, and a card slot 7 is provided on the side of the L-shaped connecting block 2 away from the scanning module 1. A spring slot 10 is provided in the middle of the top of the connecting arm 3. The inner cavity of the spring slot 10 is movably fixedly connected to a spring 13. The inner cavity of the spring slot 10 is slidably connected to a slider 11 on the side away from the spring 13, and the slider 11 is fixedly connected to the spring 13. The top of the slider 11 is fixedly connected to an angled clamping rod 12, and the angled clamping rod 12 cooperates with the card slot 7, and the connecting arm 3 rotates. When the connecting arm 3 is rotated 90 degrees, the beveled clamping rod 12 is aligned with the clamping groove 7. At this time, the rebound force of the spring 13 pushes the slider 11 and the beveled clamping rod 12 to return to their original position. The beveled clamping rod 12 is accurately inserted into the clamping groove 7, realizing the rapid deployment and locking of the connecting arm 3.
[0023] The connecting arm 3 is located on one side of the upper part of the inner cavity of the spring groove 10 and is provided with a baffle groove 15. The inner cavity of the baffle groove 15 is slidably connected to a baffle 14, and one side of the baffle 14 is fixedly connected to the slider 11. When the angled clamping rod 12 drives the slider 11 to slide into the spring groove 10, the slider 11 will synchronously drive the baffle 14 to move along the baffle groove 15, thereby closing the opening of the spring groove 10, effectively preventing impurities such as stones from entering the groove and causing the components to get stuck.
[0024] A double L-shaped plate 16 is installed on one side of the inner cavity of a group of connecting arms 3, and the double L-shaped plate 16 is located on one side of the inner cavity of the mounting cover 4, and the middle part of the double L-shaped plate 16 is slidably connected to a T-shaped slider 17, and both sides of the top of the T-shaped slider 17 are fixedly connected to spring 2 18, and one side of spring 2 18 is fixedly connected to the inner cavity of the connecting arm 3, and both sides of the bottom of the T-shaped slider 17 are fixedly connected to connecting blocks 19. When the scanning module 1 and the unfolded connecting arm 3 need to be placed on the track, the two are first aligned with the track position in the tunnel at a forty-five degree tilt angle. At this time, the roller 23 on the downwardly tilted side will first contact the inner wall of the track, and the operator continues to press the scanning module 1 and the connecting arm 3 in the tilted direction, and the roller 23 will push the connecting rod 22 and the sliding rod 21 to slide backward along the mounting plate 20, thereby driving the connecting block 19 to move; when the connecting block 19 moves, it will cause the spring 2 18 to compress on the double L-shaped plate 16 to form a buffer, and then The scanning module 1 and the raised end of the connecting arm 3 are pressed downward so that the roller 23 on the other side contacts the inner wall of the track, and at the same time, the rotating wheel 25 fits with the top of the track. The middle part of the inner cavity of the mounting cover 4 is fixedly connected to a mounting plate 20, and a motor 24 is installed on the side of the mounting plate 20 away from the T-shaped slider 17. The output end of the motor 24 away from the spring slot 10 is fixedly connected to the rotating wheel 25. After starting the motor 24, the rotating wheel 25 will rotate along the track under the action of the driving force, and the self-gravity of the scanning module 1 and the connecting arm 3 will increase the friction between the rotating wheel 25 and the track, ensuring that the movement process is stable and reliable, and realizing accurate displacement detection of the scanning module 1. The middle part of the two connecting blocks 19 is penetrated and fixedly connected with a sliding rod 21, and the sliding rod 21 penetrates the mounting plate 20 and is slidably connected. The two sliding rods 21 are fixedly connected to the connecting rod 22 on the side away from the connecting block 19, and the two connecting rods 22 are installed with rollers 23 on the side away from the sliding rod 21.
[0025] The working principle of the present invention: In actual operation, if the connecting arm 3 needs to be unfolded, the operator first holds the handle 26 and rotates the four connecting arms 3 synchronously by ninety degrees. During the rotation process, the rotating rod 5 will rotate synchronously along the rotating groove 8, and the limiting slide 6 will slide in the arc-shaped limiting groove 9 at the top of the connecting arm 3. Since the arc-shaped limiting groove 9 is designed to be semi-arc-shaped, when the limiting slide 6 slides to the end of the groove body and contacts, the connecting arm 3 just completes the ninety-degree rotation. At the same time, the connecting arm 3 rotates When the connecting arm 3 is rotated 90 degrees, the beveled clamping rod 12 is aligned with the clamping groove 7. At this time, the rebound force of the spring 13 pushes the slider 11 and the beveled clamping rod 12 to return to their original position. The beveled clamping rod 12 is accurately inserted into the clamping groove 7, realizing the rapid deployment and locking of the connecting arm 3.
[0026] When retrieving the connecting arm 3, you only need to pull the angled clamping rod 12 backward to disengage it from the clamping slot 7, and then hold the handle 26 to rotate the connecting arm 3 back to complete the storage. When the angled clamping rod 12 drives the slider 11 to slide into the spring groove 10, the slider 11 will synchronously drive the baffle 14 to move along the baffle groove 15, thereby closing the opening of the spring groove 10, effectively preventing impurities such as stones from entering the groove and causing the components to get stuck.
[0027] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
