DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-2 This application is described in further detail.

[0032] The present application embodiment discloses a railway overhead line intelligent measurement vehicle. Figure 1The railway contact network intelligent measuring vehicle includes an upper support seat 1 and a lower support seat 2. The upper support seat 1 and the lower support seat 2 are both plate-shaped, and the upper support seat 1 is located on the upper side of the lower support seat 2. A laser rangefinder 3 is installed on the upper side of the upper support seat 1, and the laser rangefinder 3 is horizontal. A first support rod 4 and a second support rod 5 are hinged on one side of the upper support seat 1 close to the lower support seat 2. The end of the first support rod 4 away from the upper support seat 1 is slidably installed on the lower support seat 2, and the end of the second support rod 5 away from the upper support seat 1 is slidably installed on the upper side of the lower support seat 2. A driving component 6 for driving the first support rod 4 and the second support rod 5 to move closer to or away from each other is provided on the lower support seat 2. The control driving component 6 drives the first support rod 4 and the second support rod 5 to move closer to or away from each other, so that the first support rod 4 and the second support rod 5 can lift or lower the upper support seat 1, thereby conveniently realizing the lifting and lowering of the upper support seat 1, and can adjust the height of the laser rangefinder 3 according to the different heights of the railway contact network, so as to facilitate the laser rangefinder 3 to perform intelligent measurement of the contact network, and overall improve the problem of inconvenient height adjustment of the upper support seat 1.

[0033] Reference Figure 1 , the first support rod 4 is hinged with a first slide 21 at one end away from the upper support seat 1, and the second support rod 5 is hinged with a second slide 22 at one end away from the upper support seat 1. The driving assembly 6 includes a bidirectional screw 61 and a driving motor 62. The bidirectional screw 61 is horizontal, and the bidirectional screw 61 is rotatably mounted on the upper side of the lower support seat 2. The first slide 21 and the second slide 22 are both provided with threaded holes adapted to the thread of the bidirectional screw 61. The first slide 21 and the second slide 22 are both threadedly connected to the bidirectional screw 61 through the threaded holes, and the threaded rotation directions of the threaded holes on the first slide 21 and the second slide 22 are opposite. Controlling the rotation of the bidirectional screw 61 can make the first slide 21 and the second slide 22 rotate relative to the bidirectional screw 61, so that the first slide 21 and the second slide 22 are close to or away from each other, thereby realizing the mutual approach or distance between the first support rod 4 and the second support rod 5.

[0034] The driving motor 62 is fixedly mounted on the upper side of the lower support seat 2 , and the output shaft of the driving motor 62 is coaxially welded with the bidirectional screw rod 61 . When the driving motor 62 is started, the bidirectional screw rod 61 can be driven to rotate.

[0035] In order to guide the sliding of the first slide 21 and the second slide 22, a slide groove 23 is provided on the lower support seat 2, the length direction of the slide groove 23 is parallel to the length direction of the bidirectional screw rod 61, a first slider 211 is fixedly provided on the first slide 21, and a second slider 221 is fixedly provided on the second slide 22, the first slider 211 and the second slider 221 are both slidably adapted to the slide groove 23, and the first slider 211 and the second slider 221 are both located in the slide groove 23. The slide groove 23 can guide the sliding of the first slide 21 and the second slide 22, thereby improving the sliding stability of the first slide 21 and the second slide 22; the first slider 211 can limit the rotation of the first slide 21 with the bidirectional screw rod 61, and the second slider 221 can limit the rotation of the second slide 22 with the bidirectional screw rod 61, thereby improving the sliding stability of the first slide 21 and the second slide 22.

[0036] The slide groove 23 is a dovetail groove, which can reduce the first slider 211 and the second slider 221 from falling out of the slide groove 23 , thereby improving the sliding stability of the first slide seat 21 and the second slide seat 22 .

[0037] The first slide 21 and the second slide 22 are both rectangular, and the length directions of the first slide 21 and the second slide 22 are parallel, and the length direction of the first slide 21 is perpendicular to the length direction of the slide slot 23. Two first support rods 4 are provided along the length direction of the first slide 21, and two second support rods 5 are provided along the length direction of the second slide 22. The first support rod 4 and the second support rod 5 are provided corresponding to the four corners of the upper support seat 1. The lengths of the first support rod 4 and the second support rod 5 are adjustable, and both ends of the first support rod 4 are ball hinged, and both ends of the second support rod 5 are ball hinged. By adjusting the lengths of the first support rod 4 and the second support rod 5, the operator levels the upper support seat 1, thereby achieving the leveling of the laser rangefinder 3.

[0038] Reference Figure 1 and Figure 2 The first support rod 4 is consistent with the second support rod 5 in size and structure. The first support rod 4 includes a support tube 41 and a support column 42. The support column 42 coaxially slides into the support tube 41. The support tube 41 is provided with a locking member 7 for locking the sliding of the support column 42. By controlling the support column 42 to slide in or out of the support tube 41, the length of the first support rod 4 or the second support rod 5 can be adjusted, and then controlling the locking member 7 can enable the first support rod 4 and the second support rod 5 to stably support the upper support seat 1.

[0039] The lower end of the support tube 41 is ball-jointed with the lower support seat 2 , and the upper end of the support tube 41 is open. The support column 42 coaxially slides into the upper end of the support tube 41 , and the upper end of the support column 42 is ball-jointed with the upper support seat 1 .

[0040] The locking member 7 is a rotating ring, which is coaxially rotatably connected to the support tube 41. The support column 42 is a threaded column, and the rotating ring is provided with an internal thread that matches the thread of the support column 42. The rotating ring is threadedly sleeved on the support column 42. Rotating the rotating ring can make the support column 42 slide into or out of the support tube 41, and stopping the rotating ring can make the support column 42 and the rotating ring relatively locked, thereby locking the sliding of the support column 42.

[0041] In order to facilitate the rotation of the rotating ring, a handle 71 is welded on the outer peripheral wall of the rotating ring. With the help of the handle 71, the operator can more conveniently rotate the rotating ring.

[0042] Reference Figure 1 and Figure 2 In order to limit the rotation of the support column 42, a limiting groove 421 is provided on the support column 42 along the length direction of the support column 42, and a limiting block 411 is fixedly provided on the inner wall of the support cylinder 41, and the limiting block 411 is located in the limiting groove 421. The limiting groove 421 and the limiting block 411 cooperate to limit the rotation of the support column 42.

[0043] By controlling the extension of the first support rod 4 and the second support rod 5 at the same time, the upper support seat 1 can be further raised, thereby increasing the height adjustment range of the upper support seat 1.

[0044] The implementation principle of the railway contact network intelligent measuring vehicle in the embodiment of the present application is: controlling the driving component 6 to drive the first support rod 4 and the second support rod 5 to move closer to or away from each other, so that the first support rod 4 and the second support rod 5 can lift or lower the upper support seat 1, thereby more conveniently realizing the lifting and lowering of the upper support seat 1, and can adjust the height of the laser rangefinder 3 according to the different heights of the railway contact network, which is convenient for the laser rangefinder 3 to measure the contact network, and overall improves the problem of the inconvenience of adjusting the height of the upper support seat 1.
