Description

Technical Field

[0001] This utility model relates to the technical field of settlement and displacement monitoring systems, specifically a pull-wire 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 in the vertical direction of 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 elements to move in the horizontal direction of the borehole and to transmit power to them from the ground. However, the existing wire-type settlement monitoring systems are not equipped with a structure that allows the monitoring elements to move in the horizontal direction of the borehole, making the installation of the monitoring elements 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 pull-wire 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: A wire-driven transmission structure for installation on the sidewall of a borehole is disclosed. This transmission structure is connected to a power source and a monitoring element in a settlement monitoring system. It includes an upper arm and a lower arm. The lower end of the upper arm is connected to the upper end of the lower arm via a rotatable first connecting shaft, forming a first connecting part for connection to the monitoring element. Both the upper end of the upper arm and the lower end of the lower arm are rotatable second connecting parts. The second connecting part of the lower arm is connected to a connecting assembly of the power source. After transmission by the power source, the second connecting parts of the upper and lower arms can move towards and away from each other, changing the distance between the first connecting parts of the upper and lower arms, allowing the monitoring element to move in a direction perpendicular to the direction of movement of the second connecting parts.

[0005] As a further embodiment of the present invention, the second connecting part includes a second connecting shaft. The upper arm and the lower arm are formed by connecting one end of two rod-shaped members through the second connecting shaft. A rod-shaped member constituting the upper arm and a rod-shaped member constituting the lower arm are connected through the first connecting shaft.

[0006] As a further embodiment of the present invention, the second connecting part further includes a receiving member, which is penetrated by a second connecting shaft, and the two axial ends of the second connecting shaft are respectively axially connected to the left and right sides of the receiving member, and the receiving member of the upper arm is fixedly connected to the connecting assembly.

[0007] As a further embodiment of the present invention, the connecting component includes a pull rope sleeve and a pull rope. The pull rope sleeve is fixedly connected to the support member of the upper arm, and the pull rope passes through the pull rope sleeve and the support member of the upper arm in sequence, and is fixedly connected to the support member of the lower arm.

[0008] As a further embodiment of the present invention, one of the first connecting portions has connecting plates on both sides, and the end of the monitoring element is located between the two connecting plates.

[0009] As a further embodiment of the present invention, a positioning plate is provided on the outer side of the first connecting part, the positioning plate is penetrated by a first connecting shaft, and the two axial ends of the first connecting shaft are respectively axially connected to the left and right sides of the positioning plate.

[0010] The beneficial effects of this utility model are as follows: Under the drive of the power source, the distance between the second connecting parts of the upper arm and the lower arm will change, and the distance between the two first connecting parts will also change. By changing the force generated by the power source through the deformation of the transmission structure itself, the monitoring element can move in the horizontal direction of the borehole, thereby realizing the installation of the monitoring element on the side wall of the borehole.

Detailed Implementation

[0016] This utility model discloses a pull-wire transmission structure for installation on the sidewall of a drilled hole, such as... Figures 1-3 As shown, the transmission structure is connected to the power source 6 and the monitoring element 9 in the settlement observation system. It includes an upper arm 1 and a lower arm 2. The lower end of the upper arm 1 is connected to the upper end of the lower arm 2 through a rotatable first connecting shaft 31, forming a first connecting part 3 connected to the monitoring element 9. The upper end of the upper arm 1 and the lower end of the lower arm 2 are both rotatable second connecting parts 4. The second connecting part 4 of the lower arm 2 is connected to the connecting assembly 61 of the power source 6. After the power source 6 is activated, the second connecting parts 4 of the upper arm 1 and the lower arm 2 can move towards and away from each other to change the distance between the first connecting parts 3 of the upper arm 1 and the lower arm 2, so that the monitoring element 9 can move in a direction perpendicular to the moving direction of the second connecting part 4.

[0017] It should be noted that after the transmission structure is connected to the connecting component 61 on the power source 6, the second connecting part 4 of the lower arm 2 is pulled by the cooperation of the power source 6 and the connecting component 61, so that the second connecting parts 4 of the upper arm 1 and the lower arm 2 move towards each other and away from each other. When the distance between the second connecting parts 4 of the upper arm 1 and the lower arm 2 changes, the distance between the two first connecting parts 3 also changes accordingly. Based on this situation, the monitoring element 9 connected to one of the first connecting parts 3 will move in a direction perpendicular to the moving direction of the second connecting part 4 as the position of the first connecting part 3 to which it is connected changes, so that the monitoring element 9 can move in a direction below the borehole and thus be installed on the side wall of the borehole. Moreover, the structure of this transmission structure is simple and easy to operate.

[0018] It needs to be further explained that, such as Figure 1 and Figure 2 As shown, the second connecting part 4 includes a second connecting shaft 41. The upper arm 1 and the lower arm 2 are both formed by connecting one end of two rod-shaped members 5 through the second connecting shaft 41. A rod-shaped member 5 that makes up the upper arm 1 and a rod-shaped member 5 that makes up the lower arm 2 are connected through the first connecting shaft 31.

[0019] The upper arm 1 and lower arm 2 are both formed by connecting one end of the two rod-shaped members 5 with a second connecting shaft 41, thus forming a second connecting part 4. When the second connecting part 4 of the lower arm 2 is moved closer to the second connecting part 4 of the upper arm 1 or further away from the second connecting part 4 of the lower arm 2 by a power source, the second connecting part 4 allows relative rotation between the upper arm 1 and the lower arm 2 at the position connected by the second connecting shaft 41. Furthermore, the first connecting shaft 31 connects the other end of the rod-shaped members 5 of the upper arm 1 and the lower arm 2, thus forming a first connecting part 3. The second connecting parts 4 of the upper arm 1 and the lower arm 2 are positioned facing each other and facing away from each other. During movement, the ends of the two rod-shaped members 5 connected by the first connecting shaft 31 rotate relative to each other, so that the rod-shaped members 5 on the opposite sides of the upper arm 1 and the lower arm 2 can move closer or further apart. When the rod-shaped members 5 on the opposite sides of the upper arm 1 and the lower arm 2 move closer to each other, the second connecting parts 4 of the upper arm 1 and the lower arm 2 also move closer to each other. At this time, the two first connecting parts 3 are in a state of moving away from each other. When the first connecting parts 3 are moving away from each other, the overall length of the transmission structure will gradually increase at the position perpendicular to the borehole, so that the monitoring element 9 can enter the soft soil layer around the borehole and thus install the monitoring element 9 on the side wall of the borehole.

[0020] Specifically, such as Figure 1 and Figure 2 As shown, the second connecting part 4 also includes a receiving member 42, which is penetrated by the second connecting shaft 41, and the two axial ends of the second connecting shaft 41 are respectively axially connected to the left and right sides of the receiving member 42. The receiving member 42 of the upper arm 1 is fixedly connected to the connecting assembly 61.

[0021] The support member 42 can protect the position where the bottom end of the lower arm 2 is connected by the second connecting shaft 41, giving the position good impact resistance, thereby ensuring that the second connecting shaft 41 is not easily deformed, so as to maintain the connection stability of the second connecting shaft 41.

[0022] More specifically, such as Figure 2 As shown, the connecting component 61 includes a pull rope sleeve 611 and a pull rope 612. The pull rope sleeve is fixedly connected to the support member 42 of the upper arm 1. The pull rope 612 passes through the pull rope sleeve 611 and the support member 42 of the upper arm 1 in sequence, and is fixedly connected to the support member 42 of the lower arm 2.

[0023] When the power source 6 is connected to the second connecting shaft 41 of the lower arm 2 via the pull rope 612, the pull rope 612 is first inserted into the pull rope sleeve 611, then passed through the receiving member 42 of the upper arm 1, and then wrapped around and fixed to the outside of the receiving member 42 of the lower arm 2, thereby realizing the connection between the power source 6 and the second connecting shaft 41 of the lower arm 2. The structure is simple and easy to operate, so that the power source 6 can control the movement of the second connecting parts 4 of the upper arm 1 and the lower arm 2 towards and away from each other by pulling the pull rope 612.

[0024] It needs to be further explained that, such as Figure 3 As shown, one of the first connecting parts 3 has connecting plates 7 on both sides, and the end of the monitoring element 9 is located between the two connecting plates 7.

[0025] The monitoring element 9 is fixed at its end by two connecting plates 7, thereby connecting the monitoring element 9 to one of the first connecting parts 3 of the transmission structure, so that the monitoring element 9 remains tightly connected to the first connecting part 3 while moving in the soft soil layer around the borehole.

[0026] It needs to be further explained that, such as Figure 4 As shown, a positioning plate 8 is provided on the outer side of the first connecting part 3. The positioning plate 8 is penetrated by the first connecting shaft 31, and the two axial ends of the first connecting shaft 31 are respectively axially connected to the left and right sides of the positioning plate 8.

[0027] The positioning plate 8 allows the transmission structure to be fixed at a certain depth within the borehole, enabling the transmission structure to swing using the first connecting part 3 connected to the positioning plate 8 as a fixed point, thus adjusting the direction in which the monitoring element 9 needs to enter the soft soil layer around the borehole.

[0028] 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.
