[0028] Trolley body 1 bottom symmetry is equipped with four rollers 2, trolley body 1 is used to support handle 3, lower support ring 4 and stepping motor 7, and roller 2 is used to support trolley body 1;Trolley body 1 top right side is welded with a group of handles 3, can hold handle 3 and push trolley body 1 to move under the support of roller 2 when using;Trolley body 1 top is fixed with a lower support ring 4, and lower support ring 4 is used to rotate and support upper support ring 5;Lower support ring 4 top is rotatably installed with an upper support ring 5, and upper support ring 5 is used to support scanning probe 6;Upper support ring 5 top is installed with a scanning probe 6, can control stepping motor 7 to drive lower support ring 4 to rotate slowly by gear 8 when using, scanning probe 6 will rotate 360 ° outside ground anchor rod in this process, so that the part below ground anchor rod ground can be scanned without dead angle and scanning information is transmitted to external display device, to realize detection effect further;Trolley body 1 top right side is also equipped with two stepping motors 7 by support, can control two stepping motors 7 to drive two gears 8 to rotate synchronously when using, two gears 8 rotate and will be matched with the gear groove of the edge position on the top of upper support ring 5 to drive upper support ring 5 to rotate on the top of lower support ring 4, so that the position of the opening on upper support ring 5 can be adjusted, and the position of scanning probe 6 can also be adjusted;The main shaft one end of two stepping motors 7 is installed with a gear 8, can control two stepping motors 7 to drive two gears 8 to rotate synchronously when using, two gears 8 rotate and will be matched with the gear groove of the edge position on the top of upper support ring 5 to drive upper support ring 5 to rotate on the top of lower support ring 4.

[0029] In the embodiments of the present disclosure, as shown in Figures 1-5 The top edge of the upper supporting ring 5 is provided with a row of gear grooves, and the gear wheels 8 at one end of the main shafts of the two stepping motors 7 are engaged with the gear grooves at the top edge of the upper supporting ring 5. In use, the two stepping motors 7 can be controlled to drive the two gear wheels 8 to rotate synchronously. When the two gear wheels 8 rotate, they will cooperate with the gear grooves at the top edge of the upper supporting ring 5 to drive the upper supporting ring 5 to rotate on the top of the lower supporting ring 4. Therefore, the position of the opening on the upper supporting ring 5 can be adjusted, and the position of the scanning probe 6 can also be adjusted.

[0030] In the embodiments of the present disclosure, as shown in Figures 1-6 The lower supporting ring 4 and the upper supporting ring 5 are both open on one side and have a circular ring structure, and the trolley body 1 is open on the left side and has a U-shaped structure. In use, the opening on the upper supporting ring 5 can be first rotated to the leftmost side. At this time, the opening on the upper supporting ring 5 is located directly above the left opening of the lower supporting ring 4. Then, the trolley body 1 can be pushed by holding the handle 3 to move under the support of the rollers 2, and the left side of the trolley body 1 and the openings on one side of the lower supporting ring 4 and the upper supporting ring 5 are aligned with the ground anchor rod. At this time, the trolley body 1 can be further pushed towards the ground anchor rod, so that the ground anchor rod can be located in the circular hole inside the lower supporting ring 4 and the upper supporting ring 5.

[0031] In the embodiments of the present disclosure, as shown in Figures 4-6 The bottom of the upper supporting ring 5 is provided with a ring-shaped protrusion, the top inside of the lower supporting ring 4 is provided with a ring-shaped groove, and the vertical sections of the ring-shaped protrusion and the ring-shaped groove are both inverted T-shaped structures. When the upper supporting ring 5 rotates, the ring-shaped protrusion at the bottom of the upper supporting ring 5 will rotate in the ring-shaped groove at the top inside of the lower supporting ring 4, so as to ensure the stability of the upper supporting ring 5 when it rotates, and the inverted T-shaped structure of the vertical sections can also avoid the upper supporting ring 5 from shaking up and down.

[0032] In the embodiments of the present disclosure, as shown in Figures 1-3 The center of the lower supporting ring 4 is located at the top middle position of the trolley body 1, and the opening on the lower supporting ring 4 is also located at the leftmost side. In use, the ground anchor rod can be located in the circular hole inside the lower supporting ring 4 and the upper supporting ring 5. At this time, the lower supporting ring 4 can be slowly rotated by controlling the stepping motor 7 through the gear wheel 8. During this process, the scanning probe 6 will rotate 360° outside the ground anchor rod, so as to scan the part below the ground anchor rod without dead angle and transmit the scanning information to the external display device, thereby achieving the detection effect.

[0033] In the embodiments of the present disclosure, as shown in Figures 1-6As shown, the stepper motor 7 is symmetrically arranged at the top right side of the trolley body 1, and the distance between the two gears 8 is greater than the width of the opening on the upper support ring 5, so that the opening on one side of the upper support ring 5 can only be located directly below one of the gears 8 during rotation, so that at least one gear 8 is always engaged with the gear slot at the top edge position of the upper support ring 5, ensuring that the stepper motor 7 can drive the upper support ring 5 to rotate normally.

[0034] The working principle of the embodiment is as follows: when the device is used to detect the state of the ground anchor rod of the railway overhead contact system, first, the two stepper motors 7 are controlled to drive the two gears 8 to rotate synchronously, and the two gears 8 rotate to cooperate with the gear slot at the top edge position of the upper support ring 5 to drive the upper support ring 5 to rotate on the top of the lower support ring 4, and then the opening on the upper support ring 5 is rotated to the leftmost position, and the stepper motor 7 is stopped at this time, and the opening on the upper support ring 5 is located directly above the opening on the left side of the lower support ring 4, and then the handle 3 is held to push the trolley body 1 to move under the support of the roller 2, and the opening on the left side of the trolley body 1 and the opening on one side of the lower support ring 4 and the upper support ring 5 are aligned with the ground anchor rod, and then the trolley body 1 is pushed towards the ground anchor rod, so that the ground anchor rod can be located in the circular hole inside the lower support ring 4 and the upper support ring 5, and then the stepper motor 7 is controlled to drive the lower support ring 4 to rotate slowly through the gear 8, and the scanning probe 6 rotates 360° on the outside of the ground anchor rod during this process, so that the ground anchor rod can be scanned without dead angle under the ground and the scanning information can be transmitted to the external display device, thereby achieving the detection effect, and because the distance between the two gears 8 is greater than the width of the opening on the upper support ring 5, the opening on one side of the upper support ring 5 can only be located directly below one of the gears 8 during rotation, so that at least one gear 8 is always engaged with the gear slot at the top edge position of the upper support ring 5, ensuring that the stepper motor 7 can drive the upper support ring 5 to rotate normally, and when the state detection of one ground anchor rod is completed, the opening on the upper support ring 5 is rotated to the leftmost position, and then the trolley body 1 is pulled to the right to disengage the ground anchor rod from the circular hole inside the lower support ring 4 and the upper support ring 5, so that the device can be moved to detect the state of other ground anchor rods.
