Description

Technical Field

[0001] The utility model relates to the technical field of railway roadbed deformation monitoring equipment, in particular to a high-speed railway expansive soil roadbed deformation monitoring device. Background Art

[0002] In order to ensure the safety of high-speed railways, it is necessary to carry out deformation monitoring operations on the expansive soil roadbed of high-speed railways, and thus railway roadbed deformation monitoring equipment is needed. The utility model patent with patent application number CN202022250870.8 discloses a railway roadbed deformation monitoring device. By stretching the handle of the movable rod upward, the movable arm is driven to contract, thereby driving the instrument box fixed on the outside of the extension arm to contract, so that the friction between the instrument box and the soil is reduced. By rotating the handle, the casing and the flat bearing at the lower end of the casing are driven to rotate, so that the instrument box is rotated, thereby adjusting the instrument box to different angles to monitor the railway roadbed. According to the technical solution disclosed therein, the existing high-speed railway expansive soil roadbed deformation monitoring device is often unable to effectively detect the slight deformation of the roadbed when in use, and it is easy to be difficult to detect because the deformation is too small. On the other hand, when performing monitoring work, it is often only possible to perform deformation detection in a certain direction, which is not conducive to ensuring the reliability of the monitoring results.

[0003] Therefore, how to design a high-speed railway expansive soil roadbed deformation monitoring device has become our current problem to be solved. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high-speed railway expansive soil roadbed deformation monitoring device to solve the problems raised in the above background technology. The utility model has a reasonable design and is relatively convenient to use, and is suitable for deformation monitoring of high-speed railway expansive soil roadbed.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a high-speed railway expansive soil roadbed deformation monitoring device, comprising a sleeve and a top plate, a connecting assembly installed on the sleeve, the connecting assembly comprising universal joint 1 and universal joint 2, a sliding assembly installed on the connecting assembly, the sliding assembly comprising a sliding sleeve and a sliding rod, a sealing assembly installed on the top of the sleeve, the sealing assembly comprising a transparent plate and a scale mark, a supporting assembly installed on the inner side of the sleeve, the supporting assembly comprising a support plate and a sliding ball, a rotating assembly installed on the sliding ball, and the rotating assembly comprising a counterweight and a rotating rod.

[0006] Furthermore, the top plate is welded to the outer side of the top end of the sleeve, and the bottom end of the sleeve is welded to the pointed cone.

[0007] Furthermore, the first universal joint is installed on one side of the sleeve, and the second universal joint is installed on the other side of the sleeve.

[0008] Furthermore, one end of the sliding sleeve is connected to one side of the sleeve through universal joint 1, one end of the sliding rod is connected to the other side of the sleeve through universal joint 2, and the other end of the sliding rod passes through the other end of the sliding sleeve and extends to the inner side of the sliding sleeve.

[0009] Furthermore, the other end of the sliding rod is connected to the inner wall of one end of the sliding sleeve through a spring, and scale lines are provided on the outer side of the sliding rod.

[0010] Furthermore, the support plate is welded to the inner wall of the bottom of the sleeve, a sliding groove is provided on the inner side of the support plate, and the sliding ball is stuck on the inner side of the sliding groove.

[0011] Furthermore, the top of the counterweight is welded to the bottom of the sliding ball, the bottom end of the rotating rod is welded to the top of the sliding ball, and the top end of the rotating rod is welded with a pointer.

[0012] Furthermore, the transparent plate is sealed and mounted on the inner wall of the top end of the sleeve, the scale mark is opened on the top of the transparent plate, and the pointer matches the scale mark.

[0013] Beneficial effects: 1. When the high-speed railway expansive soil roadbed deformation monitoring device is in use, multiple sleeves are inserted into the inner side of the expansive soil roadbed of the high-speed railway through a pointed cone by tamping the top plate, and then the sliding sleeve and the sliding rod are respectively connected to the two adjacent sleeves through universal joint 1 and universal joint 2. When the high-speed railway expansive soil roadbed produces a slight deformation, the sleeve will produce a slight deflection, and the counterweight will always remain vertically downward under the action of gravity, so that the counterweight drives the sliding ball to rotate on the inner side of the support plate, and the sliding ball drives the rotating rod to rotate, and then the position change of the pointer on the scale mark on the transparent plate can be used to check whether the sleeve is deflected, so that the slight deformation of the high-speed railway expansive soil roadbed can be effectively amplified, and the tiny deformation can be effectively monitored, thereby improving the sensitivity of the monitoring equipment.

[0014] 2. When the high-speed railway expansive soil roadbed deformation monitoring device is in use, sleeves are evenly installed on the high-speed railway expansive soil roadbed. When the high-speed railway expansive soil roadbed deforms in any direction, the sliding sleeve and the sliding rod can be driven to move through the universal joint 1 and the universal joint 2, thereby causing the sliding rod and the sliding sleeve to move relative to each other, causing the position of the scale line on the sliding sleeve corresponding to the sliding rod to change, thereby being able to monitor the deformation of the high-speed railway expansive soil roadbed in any direction, thereby improving the reliability of the monitoring results.

[0015] 3. The high-speed railway expansive soil roadbed deformation monitoring device is reasonably designed and relatively efficient and convenient to use, and is suitable for deformation monitoring of high-speed railway expansive soil roadbed. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] See also Figures 1 to 3The utility model provides a technical solution: a high-speed railway expansive soil roadbed deformation monitoring device, comprising a sleeve 1 and a top plate 3, a connecting assembly installed on the sleeve 1, the connecting assembly comprising a universal joint 4 and a universal joint 5, a sliding assembly installed on the connecting assembly, the sliding assembly comprising a sleeve 6 and a slide rod 7, a sealing assembly installed on the top of the sleeve 1, the sealing assembly comprising a transparent plate 10 and a scale mark 16, a supporting assembly installed on the inner side of the sleeve 1, the supporting assembly comprising a support plate 11 and a sliding ball 12, a rotating assembly installed on the sliding ball 12, the rotating assembly comprising a counterweight 13 and a rotating rod 14, one end of the sleeve 6 is connected to one side of the sleeve 1 through a universal joint 4, and one end of the slide rod 7 is connected to the other side of the sleeve 1 through a universal joint 4. The end is connected to the other side of the sleeve 1 through the universal joint 2 5, the other end of the slide rod 7 passes through the other end of the sleeve 6 and extends to the inner side of the sleeve 6, the other end of the slide rod 7 is connected to the inner wall of one end of the sleeve 6 through the spring 8, and the outer side of the slide rod 7 is provided with a scale line 9. The sleeve 1 is evenly installed on the high-speed railway expansive soil roadbed. When the high-speed railway expansive soil roadbed produces deformation in any direction, the universal joint 1 4 and the universal joint 2 5 can drive the sleeve 6 and the slide rod 7 to move, thereby causing the slide rod 7 and the sleeve 6 to produce relative movement, causing the position of the scale line 9 on the slide rod 7 of the sleeve 6 to change, thereby being able to monitor the deformation of the high-speed railway expansive soil roadbed in any direction, thereby improving the reliability of the monitoring results.

The support plate 11 is welded to the inner wall of the bottom of the sleeve 1, and a slide groove is provided on the inner side of the support plate 11. The slide ball 12 is stuck on the inner side of the slide groove. The top of the counterweight 13 is welded to the bottom of the slide ball 12, and the bottom end of the rotating rod 14 is welded to the top of the slide ball 12. The top of the rotating rod 14 is welded with a pointer 15. The transparent plate 10 is sealed and installed on the inner wall of the top of the sleeve 1. The scale mark 16 is provided on the top of the transparent plate 10. The pointer 15 cooperates with the scale mark 16. When in use, the top plate 3 is rammed Multiple sleeves 1 are inserted into the inner side of the expansive soil roadbed of the high-speed railway through the pointed cone 2, and then the sliding sleeve 6 and the sliding rod 7 are connected to the two adjacent sleeves 1 through the universal joint 1 4 and the universal joint 2 5 respectively. When the expansive soil roadbed of the high-speed railway is slightly deformed, the sleeve 1 will be slightly deflected, and the counterweight 13 will always remain vertically downward under the action of gravity, so that the counterweight 13 drives the sliding ball 12 to rotate on the inner side of the support plate 11, and the sliding ball 12 drives the rotating rod 14 to rotate, and then the position change of the scale mark 16 of the pointer 15 on the transparent plate 10 can be used to check whether the sleeve 1 is deflected, thereby effectively amplifying the slight deformation of the expansive soil roadbed of the high-speed railway, and effectively monitoring the tiny deformation, thereby improving the sensitivity of the monitoring equipment.

[0023] When the high-speed railway expansive soil roadbed deformation monitoring device is in use, a plurality of sleeves 1 are inserted into the inner side of the expansive soil roadbed of the high-speed railway through the pointed cone 2 by tamping the top plate 3, and then the sliding sleeve 6 and the sliding rod 7 are respectively connected to the two adjacent sleeves 1 through the universal joint 1 4 and the universal joint 2 5. When the high-speed railway expansive soil roadbed produces a slight deformation, the sleeve 1 will produce a slight deflection, and the counterweight 13 will always remain vertically downward under the action of gravity, so that the counterweight 13 drives the sliding ball 12 to rotate on the inner side of the support plate 11, and the sliding ball 12 drives the rotating rod 14 to rotate, and then the position change of the scale mark 16 on the transparent plate 10 by the pointer 15 is used to check the sleeve. Whether the cylinder 1 is deflected, it can effectively amplify the slight deformation of the high-speed railway expansive soil roadbed, and thus can effectively monitor the slight deformation, improve the sensitivity of the monitoring equipment, and evenly install the sleeve 1 on the high-speed railway expansive soil roadbed. When the high-speed railway expansive soil roadbed deforms in any direction, the universal joint 1 4 and the universal joint 2 5 can drive the sliding sleeve 6 and the sliding rod 7 to move, and then the sliding rod 7 and the sliding sleeve 6 move relative to each other, so that the position of the scale line 9 on the sliding sleeve 6 corresponding to the sliding rod 7 changes, and then the deformation of the high-speed railway expansive soil roadbed in any direction can be monitored, thereby improving the reliability of the monitoring results.
