Description

Technical Field

[0001] This utility model relates to the field of road engineering technology, and in particular to a roadbed support device with adjustable settlement. Background Technology

[0002] In the field of road construction, the stability of the roadbed is directly related to the service life of the road and driving safety. With the continuous increase in traffic flow and the increasing vehicle load, the problem of roadbed settlement is becoming more and more prominent. Existing roadbed support devices lack effective settlement monitoring and adjustment mechanisms. When uneven settlement occurs in the roadbed, it is impossible to detect and dynamically adjust in time, resulting in road surface defects such as depressions and cracks. Furthermore, the use of a single column structure has limited compressive and deformation resistance, making it prone to tilting or breaking under long-term heavy pressure. It is also difficult to effectively distribute the load, and the contact area between the base and the foundation is small, resulting in poor overall stability. Utility Model Content

[0003] This utility model relates to an adjustable settlement roadbed support device, which solves the problems mentioned in the background art of existing roadbed support devices lacking an effective settlement monitoring and adjustment mechanism, unable to respond in time to uneven settlement of the roadbed, resulting in road surface defects such as depressions and cracks, and mostly using a single column structure, which has weak compressive and deformation resistance, difficulty in distributing loads, and is prone to tilting and breaking under long-term pressure and has poor stability.

[0005] Furthermore, the supporting column is a hollow cylindrical structure, and four annular transverse reinforcing ribs are fixedly installed longitudinally at equal intervals on the inner wall of the supporting column. The four transverse reinforcing ribs are formed by six vertical reinforcing ribs arranged in a ring array and intersecting each other to form a cage shape.

[0006] Furthermore, an installation platform is fixedly installed at the bottom center of the inner cavity of the support column. The top of the outer wall of the installation platform is eave-shaped. Drainage holes are opened at equal intervals on the side wall of the support column at the corresponding height of the installation platform.

A hollow sliding sleeve is fixedly connected to the top center of the external balance plate. The top of the detection rod is connected to the roadbed through the sliding sleeve, and a support spring is connected to the bottom of the detection rod in the sliding sleeve.

[0008] Furthermore, two outer retaining rings are installed at equal intervals on the outer side wall of the hydraulic cylinder. The outer retaining rings correspond to the positions of the first and third transverse reinforcing ribs on the inner wall of the support column. The top of the outer side wall of the outer retaining ring is inclined and has notches at equal intervals.

[0010] This utility model provides an adjustable settlement roadbed support device, which has the following beneficial effects:

[0011] 1. The cage-like structure inside the support column, composed of horizontal and vertical reinforcing ribs, greatly enhances its resistance to compression and deformation, effectively distributing the load and ensuring the column remains stable under heavy pressure. The outer balance plate of the fixed base expands the contact area with the foundation, further enhancing the overall stability of the device. The eaves-like design of the mounting platform, combined with drainage holes, effectively blocks and drains accumulated water, preventing water erosion of the device and foundation, extending the service life of the device, enabling it to operate stably in various complex environments, and ensuring the long-term reliability of the roadbed.

[0012] 2. The combination of the detection slide rod, support spring, and sliding detector enables real-time and sensitive monitoring of roadbed settlement, providing accurate feedback of settlement information. The design of the sliding friction ball reduces friction between monitoring components, further improving the accuracy of monitoring data. The hydraulic cylinder and support seat are connected by the rotation of the ball socket and ball head, allowing for rapid response based on monitoring data.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] Example 1: As shown in the attached document Figure 1 To be continued Figure 6 As shown:

[0026] This utility model provides an adjustable settlement roadbed support device, comprising: a support column 1, a fixed base 2 fixedly connected to the bottom of the support column 1, a sliding sleeve 3 fixedly connected in a ring array on the outer top surface of the fixed base 2, a detection rod 6 slidably connected in the sliding sleeve 3, a sliding detector 7 fixedly installed on the top of the outer wall of the sliding sleeve 3 facing the support column 1, a hydraulic cylinder 4 fixedly installed inside the support column 1, the support column 1 being a hollow cylindrical structure, four annular transverse reinforcing ribs 101 fixedly installed longitudinally at equal intervals on the inner wall of the support column 1, the four transverse reinforcing ribs 101 being formed by six vertical reinforcing ribs 102 arranged in a ring array intersecting to form a cage shape, and an installation platform 104 fixedly installed at the middle of the bottom of the inner cavity of the support column 1. The top of the outer wall of the 4 is eave-shaped. Drainage holes 103 are provided at equal intervals on the side wall of the support column 1 at the corresponding height of the mounting platform 104. The bottom of the hydraulic cylinder 4 is fixedly installed on the mounting platform 104. Specifically, the cage-like structure formed by the transverse reinforcing ribs 101 and the vertical reinforcing ribs 102 can significantly enhance the compressive strength and deformation resistance of the support column 1, effectively disperse the load from the roadbed, and ensure that the support column 1 is not easily twisted or bent when subjected to pressure. The eave-shaped design at the top of the outer wall of the mounting platform 104 can prevent water flowing into the support column 1 from affecting the operation of the hydraulic cylinder 4. The drainage holes 103 can promptly drain the water that seeps into the support column 1 from the roadbed, preventing water from soaking and eroding the support column 1 and the foundation, extending the service life of the support device, and ensuring the stability of the roadbed.

[0027] The fixed base 2 is bolted to the foundation. Six external balance plates 201 are fixedly installed at equal intervals on the outer wall of the fixed base 2. A hollow sliding sleeve 3 is fixedly connected to the top center of the external balance plate 201. The top of the probe rod 6, which is slidably connected in the sliding sleeve 3, is connected to the roadbed via a probe connecting seat 601. A support spring 602 is connected to the bottom of the probe rod 6 in the sliding sleeve 3. Specifically, the external balance plate 201 increases the contact area between the fixed base 2 and the foundation, disperses the pressure on the fixed base 2, and enhances the stability of the fixed base 2. The top of the probe rod 6 is connected to the roadbed. When the roadbed settles, the probe rod 6 will slide downward in the sliding sleeve 3. Through the elastic deformation of the support spring 602, the settlement of the roadbed can be monitored in real time, and a certain buffer support force can be provided to the roadbed to prevent the roadbed from settling too quickly. At the same time, the support spring 602 can assist the probe rod 6 in resetting when the roadbed rises.

[0028] Two outer retaining rings 401 are evenly spaced on the outer side wall of the hydraulic cylinder 4. The outer retaining rings 401 correspond to the positions of the first and third transverse reinforcing ribs 101 on the inner wall of the support column 1. The top of the outer side wall of the outer retaining rings 401 is inclined and has notches at equal intervals. A ball socket is formed in the upper end face of the top telescopic end 402 of the hydraulic cylinder 4. A ball head is fixedly installed in the middle of the bottom end face of the support seat 5. The ball head is rotatably connected in the ball socket. Specifically, the outer retaining rings 401 cooperate with the transverse reinforcing ribs 101 on the inner wall of the support column 1 to securely install the hydraulic cylinder 4. The inclined shape and notch design of the top of the outer wall of the outer retaining ring 401 inside the support column 1 facilitates the installation and disassembly of the hydraulic cylinder 4. The telescopic end 402 of the hydraulic cylinder 4 is rotatably connected to the ball head of the support seat 5 through the ball socket, so that the support seat 5 can rotate freely within a certain range. When uneven settlement occurs in the roadbed, the hydraulic cylinder 4 can adjust the height of the support seat 5 by telescopic adjustment to compensate for the settlement difference and keep the roadbed surface flat. At the same time, the rotational connection between the ball head and the ball socket can adapt to settlement changes in different directions, improving the device's ability to cope with complex settlement situations.

[0029] The sliding detector 7 is rotatably connected to one end of the sliding sleeve 3 side wall with a sliding friction ball 701. The sliding friction ball 701 is slidably connected to the outer side wall of the detection rod 6. Specifically, the sliding friction ball 701 transforms the sliding friction between the sliding detector 7 and the detection rod 6 into rolling friction, greatly reducing the friction between the two. This makes the detection rod 6 slide more smoothly in the sliding sleeve 3, ensuring that the detection rod 6 can sensitively reflect the small settlement changes of the roadbed. This improves the accuracy and reliability of the sliding detector 7 in monitoring the roadbed settlement data, providing a precise basis for timely roadbed settlement adjustment measures, so as to control the hydraulic cylinder 4 to perform timely lifting and lowering operations, thereby ensuring the stability of the roadbed.

[0030] The specific usage and function of this embodiment are as follows:

[0031] When using this adjustable settlement roadbed support device, firstly, the fixed base 2 is securely installed on the foundation with bolts. The outer balance plate 201 is used to increase the contact area with the foundation to enhance stability. Simultaneously, the detection connecting seat 601 at the top of the detection slide rod 6 is connected to the roadbed, and the support spring 602 at its bottom is placed in the sliding sleeve 3, preparing for monitoring roadbed settlement. Next, the bottom of the hydraulic cylinder 4 is installed on the mounting platform 104 at the bottom of the inner cavity of the support column 1, and fixed by the outer retaining ring 401 cooperating with the transverse reinforcing rib 101 on the inner wall of the support column 1. Then... The ball head of the support seat 5 is rotatably connected to the ball socket of the telescopic end 402 at the top of the hydraulic cylinder 4. During the operation of the device, when the roadbed settles, the detection rod 6 slides downward under pressure in the sliding sleeve 3, and the support spring 602 deforms elastically. The sliding detector 7 sensitively captures the sliding information of the detection rod 6 with the help of the sliding friction ball 701, accurately monitors the settlement data, and then controls the extension and retraction of the hydraulic cylinder 4 based on the monitoring data. The height of the support seat 5 is flexibly adjusted through the rotational connection between the ball socket and the ball head to compensate for the settlement difference, maintain the flatness of the roadbed surface, and ensure the stability of the roadbed.

[0032] Example 2:

[0033] A scale mark is set along the length of the probe slide rod 6, and a reading window is set at the corresponding position on the outer side wall of the sliding sleeve 3, so that construction personnel can intuitively read the sliding distance of the probe slide rod 6, thereby more accurately judging the amount of roadbed settlement. In addition, a wireless transmission module is integrated on the sliding detector 7 to send the monitored roadbed settlement data to the remote monitoring terminal in real time, so that managers can keep abreast of the roadbed condition and remotely control the lifting and lowering of the hydraulic cylinder 4, thereby improving the timeliness and automation of roadbed settlement adjustment.
