Description

Technical Field

[0002] The height of the roadbed excavation and filling is the difference between the design elevation of the roadbed and the ground elevation of the center line of the road. The positive or negative value and its size indicate whether the roadbed is an embankment or a cutting and its filling height and excavation depth.

The two running mechanisms 600 are respectively assembled on the two transverse slide rails 300, the two transverse extension arms 400 are respectively installed on the two running mechanisms 600, and the two detection radars are respectively installed on the two transverse extension arms 400. The working principle and advantages of the utility model are as follows: the utility model is installed on a rail vehicle, and the rail vehicle drives the device described in the utility model to move on the railway line. During the walking process, it can be divided into a road cutting or a roadbed according to the different excavation or filling methods. In this way, it is necessary to control the two lifting brackets 200 to extend and retract in the vertical direction, and drive the lateral extension arm 400 to move along the lateral slide rail 300 through the walking mechanism 600, so that the detection radar on the lateral extension arm 400 can reach the predetermined detection position and perform the detection operation; and because the rail vehicle is in a walking state on the railway line, the two detection radars on the two lateral extension arms 400 can continuously detect both sides of the railway line, thereby improving the detection efficiency. When encountering obstacles, the walking mechanism 600 can be controlled to drive the lateral extension arm 400 to move toward the rail vehicle, thereby achieving the purpose of effective obstacle avoidance. The two lifting brackets 200 of the utility model are independent individuals, and the two can perform targeted detection and identification of the filling and excavation height on both sides of the railway line according to the specific situation. In summary, the utility model can achieve the purpose of continuous and rapid detection and identification of the filling and excavation height of the railway line, and make adaptive adjustments according to the different terrains, replacing manual detection, improving the accuracy of detection data, reducing the difficulty and workload of operations, improving the detection and identification efficiency, ensuring the engineering quality of railway construction, and avoiding the occurrence of safety accidents.

[0027] As a preferred embodiment of the present invention, Figure 2As shown, the assembly seat 100 includes a first seat body 101 and a plurality of right-angle connecting plates 102. The right-angle connecting plates 102 are installed on the first seat body 101 at intervals along the lateral direction of the railway, and each right-angle connecting plate 102 is detachably connected to the rail vehicle, thereby achieving the purpose of connecting and fixing the first seat body 101 to the rail vehicle. In this embodiment, a strip hole 103 is provided on the first seat body 101 at a position corresponding to the lifting bracket 200, and the strip hole 103 extends along the lateral direction of the railway.

The working principle and advantages of this embodiment are as follows: this embodiment controls the movement of the vertical electric cylinder 205, so that it drives the scissor-type frame 201 to extend and retract through the adapter rod 204. During the extension and retraction process, the scissor-type frame 201 drives the transverse slide rail 300 to rise and fall through the upper connecting seat 203, thereby causing the transverse extension arm 400 connected to the transverse slide rail 300 and the detection radar on the transverse extension arm 400 to rise and fall, thereby realizing the adjustment of the detection height.

In this embodiment, a first torsion spring 304 is sleeved outside the vertical connecting shaft 303, and both ends of the first torsion spring 304 are connected and fixed to the upper connecting seat 203 and the first connecting ear 302. In this embodiment, when the transverse slide rail 300 or the transverse extension arm 400 encounters an obstacle, the horizontal component of the external force applied by the obstacle to the transverse slide rail 300 or the transverse extension arm 400 drives the transverse slide rail 300 to rotate a certain angle, that is, the transverse slide rail 300 rotates a certain angle along the axis of the vertical connecting shaft 303, so that the transverse slide rail 300 and / or the transverse extension arm 400 avoid the obstacle; during this process, the first torsion spring 304 twists and stores energy, and after the obstacle avoidance is completed, the first torsion spring 304 releases energy, so that the transverse slide rail 300 returns to its original position.

In this embodiment, sliding grooves 402 are respectively provided on both sides of the transverse arm body 401, and each sliding groove 402 extends to both ends of the transverse arm body 401 along the length direction of the transverse arm body 401, and a mounting seat 500 is assembled on the transverse arm body 401. Among them, the mounting seat 500 includes a second seat body 501, and a sliding block 502 is configured at the lower end of the second seat body 501, and the sliding block 502 is assembled on the transverse arm body 401, and the sliding block 502 is slidably connected with the transverse arm body 401 through the sliding groove 402.

In this embodiment, the fixing relationship between the second base body 501 and the horizontal arm body 401 is released by loosening the locking bolt, and then the position of the sliding block 502 on the horizontal arm body 401 is slid to adjust the position of the detection radar. After the adjustment is completed, the locking bolt is tightened so that the locking bolt fixes the connection position of the second base body 501 and the horizontal arm body 401.

[0031] As a preferred embodiment of the present invention, Figure 6 , 7As shown, a vertical pin 404 is fixed on the second connecting ear 403, and the vertical pin 404 is rotatably connected to the adapter 406. A second torsion spring 405 is sleeved on the vertical pin 404, and the two ends of the second torsion spring 405 are respectively fixedly connected to the vertical pin 404 and the adapter 406. In this embodiment, when the lateral extension arm 400 contacts or collides with an obstacle, the horizontal component of the external force applied by the obstacle to the lateral extension arm 400 drives the lateral extension arm 400 to rotate a certain angle, that is, the lateral extension arm 400 rotates a certain angle along the axis of the vertical pin 404, so as to achieve the purpose of the lateral extension arm 400 avoiding obstacles; in this process, the second torsion spring twists and stores energy, and after the obstacle avoidance is completed, the second torsion spring 405 releases energy, so that the lateral extension arm 400 returns to its original position.

The vertical component of the external force applied by the obstacle to the lateral extension arm 400 drives the lateral extension arm 400 to rotate a certain angle, that is, the lateral extension arm 400 rotates a certain angle along the axis of the adapter shaft 407, so as to achieve the purpose of the lateral extension arm 400 avoiding obstacles. After the obstacle avoidance is completed, the third torsion spring 408 drives the lateral extension arm 400 to return to its original position. In this embodiment, the lateral extension arm 400 rotates along the vertical pin shaft 404 and / or the adapter shaft 407, that is, the lateral extension arm 400 can rotate horizontally and / or vertically by a certain angle, so that the lateral extension arm 400 can avoid most obstacles. When encountering a larger obstacle that cannot be avoided by the above means, the walking mechanism 600 is controlled to move so that the walking mechanism 600 drives the lateral extension arm 400 to move toward the lifting bracket 200, that is, the lateral extension arm 400 is retracted toward the lateral slide rail 300 until the lateral extension arm 400 completely avoids the obstacle.
