The locomotive signal is an important signal equipment to ensure the driving safety of the locomotive and improve the transportation efficiency. The normality of the locomotive signal is directly related to the running safety and transportation efficiency of the train. This requires that the performance and accuracy of the locomotive signal test loop itself must be good, and the good performance and accuracy of the locomotive signal test loop itself depends on the installation method of the locomotive signal test loop.

[0024] like Figures 1 to 4 As shown, a locomotive signal test loop support comprises a track 1, a fixed base 2 is fixedly installed on the surface of the track 1, a first slide groove 4 is opened on the surface of the fixed base 2, a support rod 3 is slidably installed on the inner wall surface of the first slide groove 4, a sliding mechanism 5 is provided on the surface of the fixed base 2, a fixed sleeve 6 is fixedly installed on the surface of the sliding mechanism 5, the number of the fixed sleeves 6 is two and they are symmetrically arranged on the front and rear sides of the first slide groove 4, a limiting mechanism 7 is provided on the surface of the sliding mechanism 5, a positioning mechanism 8 is provided on the surface of the fixed base 2, a buckle 9 is fixedly installed on the surface of the fixed sleeve 6, and a wire clip 10 is fixedly installed on the top of the support rod 3.
[0025] Specifically, the support rod 3 to be installed is slid through the first slide groove 4 to the inside of the fixed base 2 fixedly installed on the surface of the track 1, and the support rod 3 is initially limited in the vertical direction. The fixing sleeve 6 and the limiting mechanism 7 are driven by the sliding mechanism 5 to move from front to back to the middle until the two fixing sleeves 6 are tightly fitted. At this time, the limiting mechanism 7 is engaged with the positioning mechanism 8, and the buckle 9 on the surface of the fixing sleeve 6 is engaged. The positioning mechanism 8 cooperates with the support rod 3 and the line clip 10 fixedly installed on the top surface of the support rod 3 to further fix the support rod 3 in the horizontal direction. When the support rod 3 needs to be disassembled for maintenance, the limiting mechanism 7 can be reset by the positioning mechanism 8, thereby avoiding the position displacement of the locomotive signal test loop bracket caused by vibration, which is beneficial to the accuracy of signal detection and ensures the safety of train operation and transportation efficiency.
[0026] like Figures 1 to 4 As shown, the sliding mechanism 5 includes a second slide groove 501, the second slide groove 501 is opened on the surface of the fixed base 2 and passes through the first slide groove 4, a slider 502 is slidably installed on the inner wall surface of the second slide groove 501, the number of sliders 502 is two and they are symmetrically arranged on the front and rear sides of the first slide groove 4, the fixed sleeve 6 is fixedly installed on the surface of the slider 502, and the opposite back sides of the two sliders 502 are fixedly installed with connecting rods 503, the connecting rods 503 are slidably inserted into the front and rear faces of the fixed base 2, and a push-pull head 504 is fixedly installed on the surface of the end of the connecting rod 503 away from the slider 502.
[0027] Specifically, by pushing the push-pull head 504, the connecting rod 503 and the slider 502 are driven to slide toward each other along the inner wall surface of the second slide groove 501, and then the fixing sleeve 6 is driven to slide toward each other along the inner wall surface of the second slide groove 501 until the two fixing sleeves 6 are tightly fitted, thereby fixing the support rod 3.
[0028] like Figure 2As shown, the limiting mechanism 7 includes a through groove 701, which is opened on the surface of the slider 502. A protrusion 702 is slidably installed on the inner wall surface of the through groove 701. There are two protrusions 702 and they are arranged on the left and right. The opposite surfaces of the two protrusions 702 are fixedly installed with limiting plates 703, and the opposite surfaces of the two limiting plates 703 are fixedly connected with a spring 704.
[0029] Specifically, when the slider 502 slides on the inner wall surface of the second slide groove 501, the spring 704 is in a compressed state. At the moment when the fixing sleeve 6 is tightly fitted, the protrusion 702 slides out from the inner wall surface of the through groove 701 under the action of the elastic restoring force of the spring 704 and is clamped on the inner wall surface of the positioning mechanism 8. The limiting plate 703 makes it difficult for the protrusion 702 to fall out when sliding out, thereby ensuring the stability of the structure, facilitating the fixation of the support rod 3 and the line card 10, making the installation structure more stable, and facilitating the accuracy and stability of signal detection.
[0030] like Figures 1 to 4 As shown, the positioning mechanism 8 includes a groove 801, which is opened on the surface of the fixed base 2. There are four grooves 801, and each group of two is symmetrically arranged on the left and right side walls of the second slide groove 501. The two groups of grooves 801 are symmetrically arranged about the first slide groove 4. A slide plate 802 is slidably installed on the inner wall surface of the groove 801, and a telescopic handle 803 is slidably inserted on the top surface of the slide plate 802.
[0031] Specifically, when the fixing sleeve 6 fits tightly, the protrusion 702 is clamped on the inner wall surface of the groove 801, so that the position of the protrusion 702 is fixed. When the support rod 3 needs to be disassembled, the telescopic handle 803 can be lifted up and then a force can be applied to the second slide groove 501, so that the telescopic handle 803 drives the slide plate 802 to slide on the inner wall surface of the groove 801, and generates a force on the protrusion 702, so that the spring 704 is deformed under the action of the force, and the protrusion 702 retracts into the through groove 701. At this time, the movable limiting mechanism 7 can slide on the inner wall surface of the second slide groove 501 and drive the two fixing sleeves 6 to slide back to each other. The support rod 3 can be disassembled without being fixed, which is convenient for the inspection and maintenance of the locomotive signal test loop. The installation and disassembly of the support rod 3 are more convenient, saving time and manpower.
[0032] like Figure 1 and Figure 3 As shown, the fixing sleeve 6 is a hollow semi-cylindrical structure, the inner wall diameter of the fixing sleeve 6 is the same as the diameter of the support rod 3 , and the shape of the first sliding groove 4 is adapted to the shape of the support rod 3 .
[0033] Specifically, the inner wall diameter of the fixing sleeve 6 is the same as the diameter of the support rod 3, and the shape of the first slide groove 4 is adapted to the shape of the support rod 3, making the fixation of the support rod 3 safer and more reliable, which is beneficial to the accuracy of signal detection and the safety of train operation.
[0034] like Figures 1 to 4 As shown, the size of the groove 801 matches the size of the protrusion 702 .
[0035] Specifically, the size of the groove 801 is matched with the size of the protrusion 702, which makes the fixing structure of the support rod 3 more stable, avoids the displacement of the position of the support rod 3 caused by vibration during train operation, and is beneficial to the operation safety and transportation efficiency of the train.
[0036] To sum up: the support rod 3 to be installed is slid through the first slide groove 4 to the inside of the fixed base 2 fixedly installed on the surface of the track 1, and the support rod 3 is initially limited in the vertical direction. The fixing sleeve 6 and the limiting mechanism 7 are driven by the sliding mechanism 5 to move from front to back to the middle until the two fixing sleeves 6 are tightly fitted. At this time, the limiting mechanism 7 is engaged with the positioning mechanism 8, and the buckle 9 on the surface of the fixing sleeve 6 is engaged. The positioning mechanism 8 cooperates with the support rod 3 and the line card 10 fixedly installed on the top surface of the support rod 3 to further fix the support rod 3 and the line card 10 fixedly installed on the top surface of the support rod 3 in the horizontal direction. When the support rod 3 needs to be disassembled for maintenance, the limiting mechanism 7 can be reset by the positioning mechanism 8, thereby avoiding the position displacement of the locomotive signal test loop bracket caused by vibration, which is beneficial to the accuracy of signal detection and ensures the safety of train operation and transportation efficiency.
