Abstract
Description
Technical Field
[0001] This utility model belongs to the field of roadbed grouting technology, and in particular, it is a stabilizing device for adjusting the roadbed grouting pressure. Background Technology
[0002] After prolonged use, highway subgrades may experience settlement, necessitating reinforcement. This reinforcement process utilizes grouting machines to facilitate grouting within the subgrade. Grouting can enhance the subgrade's bearing capacity and reduce pavement settlement.
[0003] Current stabilization devices for adjusting roadbed grouting pressure can monitor the grouting pressure during operation, but require manual adjustment. However, if the pressure is too high, manual reaction time is needed, and the pressure gauge needs to be monitored for a long time, which may lead to excessive grouting. They lack the function of automatic pressure adjustment.
[0004] Therefore, in view of this situation, there is an urgent need to design and manufacture a stabilizing device for adjusting the grouting pressure of the roadbed to meet the needs of practical use. Utility Model Content
[0005] The purpose of this invention is to provide a stabilizing device for adjusting the grouting pressure of roadbed, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a stabilizing device for adjusting roadbed grouting pressure, comprising a pressure box for adjusting roadbed grouting pressure, a limiting member fixedly connected to the upper side of the pressure box, a return spring sleeved on the side of the limiting member, a support plate fixedly connected to the end of the return spring near the pressure box, the support plate sleeved with the limiting member, a second connecting rod fixedly connected to the lower side of the support plate, a piston fixedly connected to the end of the second connecting rod away from the support plate, a first connecting plate fixedly connected to the side of the support plate, and a first connecting rod fixedly connected to the side of the first connecting plate.
[0007] Preferably, a movable block is fixedly connected to the lower side of the first connecting rod, and a feeding groove is provided inside the movable block.
[0008] Preferably, the movable block is slidably connected to a housing, and a limit block is fixedly connected inside the housing.
[0009] Preferably, a first fixing plate is fixedly connected inside the outer shell, and a telescopic rod is fixedly connected to the upper side of the first fixing plate.
[0010] Preferably, a push plate is fixedly connected to the extended end of the telescopic rod, and a discharge port is fixedly connected to the lower side of the outer casing.
[0011] Preferably, a material inlet is connected to the side of the outer casing, and a support rod is fixedly connected to the side of the outer casing.
[0012] Preferably, a fixing rod is fixedly connected to the side of the outer shell, and the fixing rod is fixed to the pressure box.
[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:
[0014] This stabilizing device for adjusting roadbed grouting pressure works by causing the piston inside the pressure box to move upward as the pressure increases. This movement causes the second connecting rod, support plate, and first connecting plate to move upward. The upward movement of the first connecting plate then causes the first connecting rod and the moving block to move upward, continuously reducing the communication area between the feeding trough and the conveying port within the moving block. This results in a continuous reduction in the amount of roadbed grouting until the pressure becomes too high and there is no longer any contact area between the feeding trough and the conveying port. At this point, roadbed grouting stops, and the amount of roadbed grouting decreases as the pressure increases, thereby reducing the amount of grouting and achieving pressure regulation.
[0015] Simultaneously, the telescopic rod drives the vertical movement, which can reduce the accumulation of concrete at the grouting port and reduce the impact on grouting efficiency. Attached Figure Description

[0023] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.
[0024] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.
[0025] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.
[0026] To address the issue that while monitoring the grouting pressure during construction requires manual adjustment, excessive pressure necessitates a reaction time and prolonged monitoring of the pressure gauge, potentially leading to over-grouting, the system lacks an automatic pressure adjustment function. Figures 1 to 4The illustrated stabilizing device for adjusting roadbed grouting pressure includes a pressure box 13 for adjusting the roadbed grouting pressure. A limiting member 11 is fixedly connected to the upper side of the pressure box 13. A rubber pad is provided on the side of the limiting member 11 to provide friction for the movement of the support plate 10. A return spring 12 is sleeved on the side of the limiting member 11. The friction provided by the limiting member 11 and the return spring 12 make it necessary to apply greater pressure to cause the piston 19 to move upward. The piston 19 is tightly pressed against the inside of the pressure box 13 from the side. A support plate 10 is fixedly connected to the end of the return spring 12 near the pressure box 13. The support plate 10 is sleeved with the limiting member 11. A second connecting rod 18 is fixedly connected to the lower side of the support plate 10. A piston 19 is fixedly connected to the end of the support plate 10 away from the support plate 10. A first connecting plate 9 is fixedly connected to the side of the support plate 10. A first connecting rod 8 is fixedly connected to the side of the first connecting plate 9. A moving block 16 is fixedly connected to the lower side of the first connecting rod 8. A feeding groove 17 is opened inside the moving block 16. A housing 1 is slidably connected to the side of the moving block 16. Two limiting blocks 15 are set inside the housing 1. One limiting block 14 contacts the moving block 16 so that the feeding port 2 and the feeding groove 17 are in complete contact. The other limiting block 14 contacts the moving block 16 so that the feeding port 2 and the feeding groove 17 have no communication area, thus stopping the grouting. The limiting block 15 is fixedly connected inside the housing 1.
[0027] The outer casing 1 is internally fixedly connected to a first fixing plate 7. A telescopic rod 4 is fixedly connected to the upper side of the first fixing plate 7. A push plate 5 is fixedly connected to the extended end of the telescopic rod 4. The push plate 5 is provided with holes to facilitate the movement of concrete. A discharge port 3 is fixedly connected to the lower side of the outer casing 1. A conveying port 2 is connected to the side of the outer casing 1. A support rod 6 is fixedly connected to the side of the outer casing 1. A fixing rod 14 is fixedly connected to the side of the outer casing 1. The fixing rod 14 is fixed to the pressure box 13.
[0028] All structures and instruments are treated with heat-resistant and waterproof materials.
[0029] The telescopic rod 4 is a conventional device. Its working principle, size, and model are irrelevant to the function of this application, so they will not be described in detail. It is controlled by a remote control switch. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.
[0030] Working principle
[0031] This stabilizing device for adjusting the grouting pressure of the roadbed operates as follows: During use, concrete is transported and grouted through the conveying port 2 and the feeding trough 17. As the grouting pressure increases, the pressure pushes the piston 19 inside the pressure box 13 upward. The return spring 12 requires even greater pressure to cause the piston 19 to move upward. The upward movement of the piston 19 drives the second connecting rod 18 upward, which in turn drives the first connecting plate 9 upward, which in turn drives the first connecting rod 8 upward. The upward movement of the first connecting rod 8 then drives the moving block 16, causing the contact area between the conveying port 2 and the feeding trough 17 to continuously decrease. As the pressure increases, the contact area between the conveying port 2 and the feeding trough 17 continues to shrink until it disappears, stopping the grouting. Simultaneously, the telescopic rod 4 is activated, driving the push plate 5 to move and preventing concrete accumulation.
