[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figs. 1 to 3 This utility model provides a technical solution.

[0020] An adjustable grip railway embedded component includes an anchor rod 1 and a bolt rod 2. The bolt rod 2 is coaxially mounted on the top of the anchor rod 1, and a threaded rod 3 is coaxially fixedly connected to the bottom of the bolt rod 2. The threaded rod 3 and the anchor rod 1 are rotatably connected, allowing the threaded rod 3 to rotate relative to the anchor rod 1 around its axis. A threaded cap 5 is threaded onto the surface of the threaded rod 3. Both ends of the threaded cap 5 are symmetrically rotatably connected to upper connecting rods 6. Both ends of the anchor rod 1 are symmetrically fixedly connected to fixing blocks 10. Adjusting plates 7 are rotatably connected to the surfaces of the two fixing blocks 10. The adjusting plates 7 can swing around the hinge points of the fixing blocks 10. One end of each of the two upper connecting rods 6 is rotatably connected to the top surface of the two adjusting plates 7, forming a linkage transmission structure. A sliding groove 12 is provided axially on the surface of the anchor rod 1. An adjusting component for adjusting the tilt angle of the adjusting plate 7 is provided in the sliding groove 12. The adjusting component includes a threaded cap 5 and an upper connecting rod 6. The width of the sliding groove 12 is adapted to the range of motion of the threaded cap 5 and the upper connecting rod 6, allowing them to slide up and down along the groove as the threaded cap 5 rises and falls.

[0021] Each adjusting plate 7 has a lower connector 8 fixedly connected to its bottom end, and each lower connector 8 has a reinforcing rod 9 rotatably connected to its bottom end.

[0022] When the rotating bolt rod 2 is rotated, the threaded rod 3 coaxially connected to its bottom end rotates synchronously. Through the threaded transmission, the threaded cap 5 is driven to rise and fall along the axial direction of the threaded rod 3. The linear motion of the threaded cap 5 is converted into the swing of the adjusting plate 7 through the upper connecting rods 6 at both ends. One end of the upper connecting rod 6 tilts as the threaded cap 5 rises and falls, and the other end pushes the adjusting plate 7 to rotate around the hinge point of the fixed block 10, thereby changing the tilt angle of the adjusting plate 7. During this process, the lower connecting head 8 at the bottom of the adjusting plate 7 swings synchronously with the adjusting plate 7. The reinforcing rod 9 connected to it adaptively adjusts its posture through the rotating connecting joint, and always hangs down naturally and remains vertical under the action of gravity.

[0023] For example, when the bolt rod 2 is rotated clockwise, the coaxially fixed threaded rod 3 rotates clockwise synchronously, driving the threaded cap 5 to move upward along the axial direction of the threaded rod 3 through the threaded transmission. As the threaded cap 5 rises, the angle between the upper connecting rod 6 at both ends and the horizontal plane gradually decreases, and the upper connecting rod 6 tends to be horizontal. This, in turn, pushes the adjusting plate 7 to unfold outward around the rotation connection point of the fixed block 10, increasing the tilt angle of the adjusting plate 7. Conversely, if the bolt rod 2 is rotated counterclockwise, the threaded cap 5 moves downward, the angle between the upper connecting rod 6 and the horizontal plane increases and tends to be vertical, and the adjusting plate 7 retracts inward, decreasing the tilt angle.

[0024] A limiting ring 4 is coaxially fixedly connected to the surface of the threaded rod 3. The limiting ring 4 is rotatably connected to the anchor rod 1. The limiting ring 4 ensures that the threaded rod 3 does not undergo axial displacement within the anchor rod 1.

[0025] It also includes a steel pad 11, with the bolt rod 2 moving through the surface of the steel pad 11, and the connection between the bolt rod 2 and the anchor rod 1 located below the steel pad 11.

[0026] Specifically, this scheme involves rotating the bolt rod 2 to drive the adjustment plate 7 to change its tilt angle, thereby adjusting the contact area between the embedded part and the foundation. Rotating the bolt rod 2 causes the coaxially connected threaded rod 3 to rotate synchronously. Through threaded transmission, the threaded cap 5 moves up and down along the axis of the threaded rod 3. The lifting and lowering of the threaded cap 5 is converted into the swinging of the adjustment plate 7 by the upper connecting rods 6 at both ends. When the threaded cap 5 rises, the upper connecting rod 6 tends to be horizontal, pushing the adjustment plate 7 to unfold outward around the rotation connection point of the fixed block 10; when the threaded cap 5 falls, the upper connecting rod 6 tends to be vertical, and the adjustment plate 7 retracts inward. The tilt angle of the adjustment plate 7 determines its contact range with the surrounding foundation and its support posture.

[0027] The lower connector 8 at the bottom of the adjusting plate 7 is rotatably connected to the reinforcing rod 9, so that the reinforcing rod 9 always remains vertical under the action of gravity, ensuring that the reinforcing rod 9 can adaptively adjust its posture when the adjusting plate 7 swings, forming a stable vertical support with the foundation.

[0028] For example, in soft soil foundations, rotating bolt rod 2 clockwise causes threaded cap 5 to move upwards, and upper connecting rod 6 pushes adjusting plate 7 outwards, increasing the tilt angle and the contact area between adjusting plate 7 and the soil. When it withstands the upward pull-out force in a near-horizontal posture, more soil self-weight can be used to form pull-out resistance. In concrete foundations, rotating bolt rod 2 counterclockwise causes threaded cap 5 to move downwards, and adjusting plate 7 to retract inwards. When the tilt angle is at a moderate position, such as 30° to 45°, the contact area between its plane and the concrete foundation is moderate. This can increase the bonding path of the concrete through the tilted surface, and avoid insufficient bonding caused by an excessively large angle.
