Description

Technical Field

[0001] This utility model relates to the technical field of settlement and displacement monitoring systems, specifically to a wire-type borehole installation force transmission device. Background Technology

[0002] In the current process of soft soil foundation treatment, settlement monitoring of soft soil layers generally uses a settlement observation system to acquire settlement data. However, the monitoring elements used to acquire data in the settlement observation system need to be installed inside the borehole.

[0003] In existing settlement monitoring systems, the installation of monitoring elements in the vertical direction of the borehole is simpler than that on the borehole sidewall. However, this requires a force transmission device from the ground to the borehole depth to alter the shape of the transmission structure. This movement of the monitoring element in the horizontal direction of the borehole facilitates its installation on the sidewall. In contrast, the force transmission device in existing wire-guided settlement monitoring systems is inconvenient to operate, and the amount of information received from the ground is limited. This results in ground personnel being unclear about the location of the monitoring element deep within the borehole, leading to blind operation of the force transmission device and ultimately affecting the effectiveness of installing the monitoring element on the borehole sidewall. Utility Model Content

[0004] To address the technical deficiencies in the background technology, this utility model proposes a wire-driven drilling installation force transmission device, which solves the aforementioned technical problems and meets practical needs. The specific technical solution is as follows: This utility model discloses a pull-wire type drilling installation force transmission device, including a support plate, a pull-wire sleeve, and a pull wire. The pull wire is fitted inside the pull-wire sleeve and is fixedly connected to one end of the support plate. A connecting seat is provided in the middle of the support plate, and the connecting seat is provided with a lever structure. The pull wire inside the pull-wire sleeve passes through the end of the support plate connected to the pull-wire sleeve and extends to the top of the support plate to connect with one end of the lever structure. The lever structure rotates around one end of the connecting seat as the rotation center, thereby changing the height position of the end of the lever structure connected to the pull wire, so as to adjust the length of the pull wire extending above the pull-wire sleeve.

[0005] As a further embodiment of the present invention, the connecting seat is arranged to extend toward the space above the support plate. The lever structure includes a connecting plate and a connecting shaft. The connecting shaft is connected through the middle of the connecting plate and is axially connected to the end of the connecting seat away from the support plate. The pull wire is fixedly connected to one end of the connecting plate.

[0006] As a further embodiment of this utility model, the position where the connecting plate connects to the connecting shaft is an extension, and the extension is perpendicular to the middle part of the connecting plate.

[0007] As a further embodiment of this utility model, the connecting plate is provided with a first reference block at the end of the pull wire fixing connection position.

[0008] As a further embodiment of this utility model, the portion of the connecting plate away from the pull wire side is a handle whose arrangement direction is not in the same straight line direction as the rest of the connecting plate.

[0009] As a further embodiment of this utility model, the surface of the pull wire is provided with scales or marks, and the surface of the support plate at the position where the pull wire passes through is provided with a second reference block.

[0010] As a further embodiment of this utility model, the bottom surface of the support plate is a plane.

[0011] The beneficial effects of this utility model are as follows: The force transmission device is placed on the ground outside the top of the borehole, and its pull line is connected to the transmission structure inside the borehole. The length of the pull line pulled out of the pull line sleeve is controlled by the lever structure, so as to realize the force control of the transmission structure deep in the borehole from the ground surface. This controls the transmission effect of the transmission structure inside the borehole on the monitoring element, allowing the monitoring element to be installed on the side wall of the borehole. This facilitates the operation of installing the monitoring element on the side wall of the borehole. The structure is simple, and the operators on the ground can also judge the position of the monitoring element deep in the borehole according to the pull line of the force transmission device, ensuring that the monitoring element can be accurately installed on the side wall inside the borehole.

Detailed Implementation

[0017] This utility model discloses a pull-wire type drilling installation force transmission device, such as Figures 1-4As shown, the assembly includes a support plate 1, a pull sleeve 2, and a pull wire 3. The pull sleeve 2 houses the pull wire 3. The pull sleeve 2 is fixedly connected to one end of the support plate 1. The support plate 1 has a connecting seat 11 in the middle, and the connecting seat 11 has a lever structure 4. The pull wire 3 inside the pull sleeve 2 passes through the end of the support plate 1 connected to the pull sleeve 2 and extends to the top of the support plate 1 to connect with one end of the lever structure 4. The lever structure 4 rotates around one end of the connecting seat 11 as its rotation center, changing the height position of the end of the lever structure 4 connected to the pull wire 3, thereby adjusting the length of the pull wire 3 extending above the pull sleeve 2.

[0018] It should be noted that after the force transmission device is placed above the borehole in the soft soil foundation, its pull wire 3 is connected to the transmission structure inside the borehole. The pull wire sleeve 2 is also located inside the borehole. When the force transmission device is working, the surveyor can pull the lever structure 4 away from the end connected to the pull wire 3, using the connection point between the connecting seat 11 and the lever structure 4 as the rotation center, so that the end of the lever structure 4 connected to the pull wire 3 moves in the space above the pull wire sleeve 2. The lever structure 4 is used to control the length of the pull wire pulled out of the pull wire sleeve 2. Since the power input position of the transmission structure is connected to the pull wire 3, the change in the length of the pull wire 3 extending out of the borehole below the pull wire sleeve 2 will change the shape of the transmission structure. The installation of the monitoring element on the side wall of the borehole is controlled by the position change of the two horizontal ends of the transmission structure. Therefore, the surveyor can use this force transmission device in conjunction with the transmission structure inside the borehole to realize the conversion of force in the vertical direction to the horizontal direction, thereby realizing the installation of the monitoring element on the side wall of the borehole.

[0019] It needs to be further explained that, such as Figure 2 and Figure 3 As shown, the connecting seat 11 is arranged to extend toward the space above the support plate 1. The lever structure 4 includes a connecting plate 41 and a connecting shaft 42. The connecting shaft 42 is connected through the middle of the connecting plate 41 and is axially connected to the end of the connecting seat 11 away from the support plate 1. The pull wire 3 is fixedly connected to one end of the connecting plate 41.

[0020] After the connecting plate 41 is axially connected to the connecting seat 11 via the connecting shaft 42, when one end of the connecting plate 41 is subjected to force, it will rotate around the position where the connecting shaft 42 and the connecting seat 11 form the axial connection center. The end of the connecting plate 41 that is not subjected to force, namely the end of the connecting plate 41 to which the pull wire 3 is connected, will move in the opposite direction to the end of the connecting plate 41 subjected to force in the height direction of the force transmission device. This enables the operation of lifting or lowering the pull wire 3 in the pull wire sleeve 2, thereby adjusting the shape of the transmission structure to provide power to the monitoring element. The operation and structure are relatively simple.

[0021] Specifically, such as Figure 2 and Figure 3 As shown, the connection between the connecting plate 41 and the connecting shaft 42 is an extension 411, and the extension 411 is perpendicular to the middle part of the connecting plate 41.

[0022] The extension part 411 can expand the rotation range of the connecting plate 41, thereby increasing the movable range of the connecting plate 41 in the space above the pull wire sleeve 2. This allows the force transmission device to control the length of the longer pull wire 3 in deep boreholes, so as to meet the operational requirements of the monitoring element when it is installed in deep boreholes and expand the applicability of the force transmission device.

[0023] Specifically, such as Figure 2 and Figure 3 As shown, the connecting plate 41 has a first reference block 5 at the end of the fixed connection position of the pull wire 3.

[0024] The first reference block 5 is set so that when the connecting plate 41 is connected to the pull wire 3, the end face of the first reference block 5 is used as a reference to form the zero point position of the pull wire 3. This makes it convenient for the measurement personnel to calculate the distance that the monitoring element moves to the side wall of the borehole under the action of the horizontal thrust of the transmission structure by measuring the change of the pull wire 3 during the process of installing the monitoring element to the borehole side wall.

[0025] Specifically, such as Figure 3 As shown, the portion of the connecting plate 41 away from the pull wire 3 is a handle 412 whose arrangement direction is not in the same straight line direction as the rest of the connecting plate 41.

[0026] The handle 412 facilitates the operation of the measuring personnel when pulling the connecting plate 41. Moreover, the direction of the handle 412 is not in the same straight line as the rest of the connecting plate 41. When the measuring personnel pull the connecting plate 41 to rotate around the position where the connecting shaft 42 and the connecting seat 11 form an axial connection, the handle 412 abuts against the support plate 1 to limit the connecting plate 41, preventing excessive rotation of the connecting plate 41 and ensuring that the pull wire 3 can be pulled normally.

[0027] It needs to be further explained that, such as Figure 3 As shown, the surface of the pull wire 3 is provided with scales or marks, and the surface of the support plate 1 at the position where the pull wire 3 passes through is provided with a second reference block 6.

[0028] The second reference block 6 aligns with the scale or markings on the surface of the pull wire 3, allowing the measuring personnel to understand the current length of the pull wire 3 extending above the pull wire sleeve 2. By observing the changes in the values ​​of the scale or markings on the surface of the pull wire 3 before and after adjusting its length, the shape of the current transmission structure and the position of the monitoring element at the horizontal end of the transmission structure can be calculated. This allows for a quick and clear determination of the monitoring element's location, facilitating the measuring personnel's adjustment of the monitoring element's position.

[0029] It needs to be further explained that, such as Figures 1-4 As shown, the bottom surface of the support plate 1 is a plane.

[0030] The fact that the bottom surface of the support plate 1 is set to be flat makes it easier to place the force transmission device on the ground and also helps the force transmission device to remain stable during the measurement process.

[0031] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
