Description

Technical Field

[0001] This invention relates to the field of roadbed grouting technology, specifically to a railway roadbed grouting reinforcement device. Background Technology

[0002] During use, roadbeds may develop depressions and cracks due to geological settlement, requiring grouting reinforcement. Therefore, a railway roadbed grouting reinforcement device is needed. Publication (Announcement) No.: CN218346147U, describes a railway roadbed grouting reinforcement device. First, the device is placed in a fixed position. Then, the handle is turned, causing the rotating rod to rotate, which in turn rotates the cone rod, screwing the cone rod into the fixed position on the bottom surface, thus completing the device's fixation. Next, a grouting pipe of appropriate diameter is placed into the circular through groove, aligning the positioning groove with the rotating wheel. A spring then drives the rotating wheel to clamp the grouting pipe. In actual operation, after the device is placed, minor adjustments to the grouting point may be necessary, requiring overall relocation. Therefore, a railway roadbed grouting reinforcement device is needed that allows for fine-tuning of the grouting point even after placement. Summary of the Invention

[0003] To address the above situation and overcome the shortcomings of existing technologies, this solution provides a railway subgrade grouting reinforcement device, achieved through the following specific technical means: It includes a device base, with three sets of vertical frames arranged around its perimeter. Each vertical frame has a control screw rotatably mounted on it, and a mounting seat is slidably fitted onto the control screw through a threaded hole. Each of the three sets of vertical frames is movably connected to a movable seat via a connecting arm. The movable seat has an installation hole for inserting a grouting pipe. Simultaneously, the device base has a window through which the bottom end of the grouting pipe passes and is inserted into the foundation. The synchronous rotation of the three sets of control screws controls the smooth raising and lowering of the movable seat. Furthermore, the rotation of one or two sets of control screws controls the lateral movement of the movable seat, adjusting the grouting position.

[0004] Preferred technical solution 1: The vertical frame is equipped with a motor connected to the control lead screw.

[0005] Preferred technical solution 2: The connecting arm includes a horizontal shaft 1, a horizontal shaft 2, and an arm rod. The horizontal shaft 1 is rotatably mounted on a support on the mounting base, and the horizontal shaft 2 is rotatably mounted on a support on the side of the movable base. Both ends of the horizontal shaft 1 and the horizontal shaft 2 are provided with convex shafts, and both ends of the arm rod are rotatably sleeved on the convex shafts on the horizontal shaft 1 and the horizontal shaft 2, respectively.

[0006] Preferred technical solution 3: The movable seat is provided with a grouting pipe clamping mechanism.

[0007] Preferred technical solution four: The grouting pipe clamping mechanism includes a rotating ring, a pushing rod, and a clamping plate. A through-hole groove is provided on the side wall of the movable seat. The clamping plate is connected to the inner side wall of the movable seat in the same direction as the side of the mounting hole through a spring and is sealed at the inner end of the through-hole groove. At the same time, the rotating ring is rotatably disposed in an annular groove on the movable seat and surrounds the mounting hole. The pushing rod is hinged to the inner wall of the rotating ring and its rear end, which extends out of the through-hole groove, contacts the clamping plate wall. A limiting shaft is provided in the through-hole groove, and a limiting groove is provided on the pushing rod. The limiting shaft is slidably disposed in the limiting groove. Multiple sets of through-hole grooves are provided along the periphery of the movable seat. The number of pushing rods and clamping plates is equal to the number of through-hole grooves and corresponds one-to-one. The rotation of the rotating ring synchronously controls the swing posture of multiple sets of pushing plates, thereby controlling the state of multiple sets of clamping plates.

[0008] Preferred technical solution five: Gear one is sleeved on the outer side of the rotating ring, motor two is installed inside the movable seat, and gear two is installed on the output shaft of motor two, and gear two meshes with gear one.

[0009] Preferred technical solution six: A fixed rod is connected to the clamp plate, the fixed rod is slidably inserted into the channel opened on the movable seat, and the spring is located in the channel and connected to the fixed rod, with one end of the spring connected to the inner side wall of the movable seat.

[0010] Preferred technical solution seven: The arm is provided at both ends of the first horizontal axis and the second horizontal axis, and the first horizontal axis, the second horizontal axis and the two sets of arms form a parallelogram.

[0011] The above structure gives this solution the following advantages:

[0012] 1. The rotation of one or two of the three sets of control screws can control the lateral movement of the movable seat to adjust the grouting position. The synchronous rotation of the three sets of control screws can control the smooth lifting and lowering of the movable seat, actively inserting the grouting pipe into the foundation.

[0013] 2. The special parallelogram structure of the connecting arm enables smooth lateral movement of the movable seat, preventing it from tilting during lateral movement;

[0014] 3. The rotation of the rotating ring can simultaneously control multiple sets of clamps to clamp and fix the grouting pipe. Attached Figure Description
