Description

Technical Field

[0001] This utility model relates to the field of settlement and displacement monitoring systems, specifically a hydraulic transmission structure for installation on the sidewall of a borehole. 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 monitoring elements used to acquire data are generally installed vertically in the borehole. If it is necessary to install them on the sidewall of the borehole, a transmission structure needs to be installed inside the borehole to allow the monitoring element to move horizontally in the borehole and to transmit power to it from the ground. However, existing wire-type settlement monitoring systems are not equipped with a structure that allows the monitoring element to move horizontally in the borehole. Moreover, the operation of the components used to move the monitoring element in wire-type settlement monitoring systems is difficult, which makes the installation process of the monitoring element on the sidewall of the borehole difficult. Utility Model Content

[0004] To address the technical deficiencies in the background art, this utility model proposes a hydraulic transmission structure for installation on the sidewall of a borehole, which solves the aforementioned technical problems and meets practical needs. The specific technical solution is as follows: This utility model discloses a hydraulic transmission structure for mounting a monitoring element to the sidewall of a borehole. The transmission structure includes a support and a hydraulic actuator. The support is located inside the borehole and moves along the height direction of the borehole. The hydraulic actuator is located on top of the support with its output end facing the sidewall of the borehole. A hydraulic system is provided on the ground above the borehole. The hydraulic actuator is connected to the hydraulic system through a pipe and, driven by the hydraulic system, moves the monitoring element connected to its output end toward the sidewall of the borehole.

[0005] As a further embodiment of the present invention, the top of the support is provided with at least two hydraulic actuators, the output ends of which are all oriented away from the central axis of the support.

[0006] As a further embodiment of this utility model, the hydraulic actuator is a telescopic hydraulic cylinder.

[0007] As a further embodiment of this utility model, the hydraulic actuator is a bidirectional hydraulic cylinder.

[0008] As a further embodiment of the present invention, the top surface of the support is provided with a connecting part for connecting with the hanging device.

[0009] As a further embodiment of this utility model, the side wall of the support is fitted with the side wall of the drill hole.

[0010] As a further embodiment of this utility model, the hydraulic system includes a hydraulic pump and a controller. The bottom of the hydraulic pump is provided with a base and is set on the ground above the drill hole through the base. The controller is set on the outer surface of the base of the hydraulic pump. The hydraulic pump is connected to the input end of the hydraulic actuator through a pipeline.

[0011] The beneficial effects of this utility model are as follows: After the stable support is located in the borehole, the transmission structure can drive the monitoring element to move in the horizontal direction of the borehole through the cooperation of the hydraulic system and the hydraulic actuator, thereby realizing the operation of installing the monitoring element on the side wall of the borehole. The structure is simple and the operation is convenient. Attached Figure Description

Detailed Implementation

[0017] This utility model discloses a hydraulic transmission structure for installation on the sidewall of a borehole, such as... Figure 1 and Figure 4 As shown, the transmission structure is used to install the monitoring element 6 onto the side wall of the borehole 5. It includes a support 1 and a hydraulic actuator 2. The support 1 is located inside the borehole 5 and moves along the height direction of the borehole 5. The hydraulic actuator 2 is located on top of the support 1 and its output end faces the side wall of the borehole 5. A hydraulic system 3 is provided on the ground above the borehole 5. The hydraulic actuator 2 is connected to the hydraulic system 3 through a pipe 4 and, driven by the hydraulic system 3, realizes the movement of the monitoring element 6 connected to the output end toward the side wall of the borehole 5.

[0018] It should be noted that after the transmission structure is placed inside the borehole 5, the position of the control support 1 inside the borehole 5 is determined to determine the position of the monitoring element 6 connected to the output end of the hydraulic actuator 2 inside the borehole 5. Then, through the operation of both the hydraulic system 3 and the hydraulic actuator 2, the hydraulic actuator 2 pushes the monitoring element 6 into the side wall of the borehole 5, thereby realizing the installation of the monitoring element 6 onto the side wall of the borehole 5.

[0019] The transmission structure uses hydraulic transmission to move the monitoring element 6 in the horizontal direction of the borehole 5. This transmission method is simple and direct, and the monitoring element 6 can be installed on the side wall of the borehole 5. The transmission structure has few components and a simple overall structure, and it is also convenient to move the monitoring element 6 in the horizontal direction of the borehole 5.

[0020] It needs to be further explained that, such as Figure 2 As shown, the top of the support 1 is provided with at least two hydraulic actuators 2, and the output ends of the hydraulic actuators 2 are all oriented away from the central axis of the support 1.

[0021] The top of the support 1 can be equipped with multiple hydraulic actuators 2. When the transmission structure is working, the monitoring element 6 can be installed at multiple positions on the side wall of the borehole 5 at the same time. Specifically, when the hydraulic actuator 2 is a telescopic hydraulic cylinder, the telescopic hydraulic cylinder is controlled by the hydraulic system 3. The telescopic hydraulic cylinder drives the monitoring element 6 to move in the horizontal direction of the borehole 5 and finally install it on the side wall of the borehole 5 by extending its working end.

[0022] It needs to be further explained that, such as Figure 3 As shown, the hydraulic actuator 2 is a bidirectional hydraulic cylinder.

[0023] When a bidirectional hydraulic cylinder is used to drive the monitoring element 6, the monitoring element 6 can be installed on both working ends of the bidirectional hydraulic cylinder. One stroke of the bidirectional hydraulic cylinder can simultaneously install two monitoring elements 6 on the side wall of the borehole 5, thus adding a hydraulic actuator 2 to install the monitoring element 6 on the side wall of the borehole 5.

[0024] It needs to be further explained that, such as Figure 4 As shown, the top surface of the support 1 is provided with a connecting part 11 for connecting with the hanging device 7.

[0025] The top of the support 1 is connected to the hanging device 7 via the connecting part 11. The position of the support 1 in the borehole 5 is controlled by the hanging device 7, thereby controlling the position of the hydraulic actuator 2 in the borehole 5 to determine the installation position of the monitoring element 6 on the side wall of the borehole 5.

[0026] It needs to be further explained that, such as Figure 4 As shown, the side wall of the support 1 is in contact with the side wall of the drill hole 5.

[0027] When the side wall of the support 1 is in contact with the side wall of the borehole 5, the support 1 is more stable when it moves in the height direction of the borehole 5, which can avoid the impact of the shaking of the support 1 on determining the installation position of the monitoring element 6 on the side wall of the borehole 5.

[0028] It needs to be further explained that, such as Figure 4 As shown, the hydraulic system 3 includes a hydraulic pump 31 and a controller 32. The bottom of the hydraulic pump 31 is provided with a base 33, and the base 33 is used to set the system above the drill hole 5 on the ground. The controller 32 is set on the surface of the base 33 outside the hydraulic pump 31. The hydraulic pump 31 is connected to the input end of the hydraulic actuator 2 through a pipe 4.

[0029] The controller 32 can control the operation of the hydraulic pump 31 and the hydraulic actuator 2. The hydraulic pump 31 pumps pressurized oil to the hydraulic actuator 2 to provide power for the operation of the hydraulic actuator 2. Then, the working end of the hydraulic actuator 2 drives the monitoring element 6 to be installed on the side wall of the borehole 5.

[0030] 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.
