DETAILED DESCRIPTION

[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0024] It should be understood that the orientation or position relationship indicated by terms such as "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0025] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0026] Please also read Figures 1 to 14 The pile foundation settlement monitoring device provided in the present application is now described. The pile foundation settlement monitoring device provided in the present application comprises a base 1 , a lever arm 2 and a positioning seat 3 .

[0027] The base 1 is used to be fixed on the ground outside the pile foundation settlement area; it should be noted that the fixing area of ​​the base 1 is usually selected as the edge of the pile foundation settlement area under normal conditions. The purpose of this design is that when the pile foundation has a predictable settlement, the base 1 can avoid the impact of this settlement and ensure the stability of its main structure. When the pile foundation has an unpredictable settlement that exceeds the predicted result, the base 1 will undergo a synchronous settlement phenomenon whose degree is less than the settlement of the pile foundation. In order to ensure the effective monitoring of the pile foundation settlement monitoring equipment, the base 1, or some components on the base 1, needs to be leveled when obtaining the monitoring results.

[0028] There is a swing member 4 hinged to the base 1 above. It should be pointed out that, unlike a unidirectional hinge, the hinge relationship here has multiple degrees of freedom, that is, when the base 1 remains in a vertical state, the swing member 4 can swing with the horizontal direction as the axis at multiple different angles.

[0029] A support structure 5 is provided between the base 1 and the swinging member 4, and the swinging of the swinging member 4 relative to the base 1 can be limited by the support structure 5 so that the length direction of the swinging member 4 is parallel to the up-down direction. Similarly, when the base 1 sinks and tilts, the tilt angle of the swinging member 4 can be adjusted by the support structure 5 so that the upper end of the swinging member 4 is reset.

[0030] The lever arm 2 is connected to the upper end of the swing member 4 by rotation in the horizontal direction, and its rotation axis is perpendicular to the direction of the base 1 toward the pile foundation. In this embodiment, the two ends of the lever arm 2 are respectively connected with a mounting seat 10 and an arc-shaped rack 20; wherein, the distance between the mounting seat 10 and the rotation axis of the lever arm 2 is smaller than the distance between the arc-shaped rack 20 and the rotation axis of the lever arm 2.

[0031] In actual use, the mounting seat 10 is used to be connected to the pile foundation so that when the pile foundation settles, the lever arm 2 is driven to rotate synchronously.

[0032] The positioning seat 3 is used to be fixed on the ground of the base 1 facing away from the pile foundation settlement area, and the positioning seat 3 has a monitoring gear 31 rotatably connected thereto and meshing with the arc-shaped rack 20, so that when the lever arm 2 rotates, the monitoring gear 31 rotates synchronously.

[0033] In combination with the above content, it should be particularly noted that when the base 1 tilts due to settlement, although the swing member 4 can be moved to a position close to the initial position by adjusting the support structure 5, the connection position between the swing member 4 and the lever arm 2 is displaced from the initial state. However, since the displacement is small and does not cause the separation of the arc rack 20 and the monitoring gear 31, this error can usually be accepted and ignored. However, in order to further improve the stability of the device during use, how to eliminate this error is also described in detail in the following text; for the sake of convenience, this error is defined as a position error.

[0034] In the embodiment of the present application, the assembly of the equipment can be completed by fixing the base 1 and the positioning seat 3, and connecting the mounting seat 10 and the pile foundation; on this basis, when the pile foundation sinks, the lever arm 2 will swing synchronously, causing the arc-shaped rack 20 to swing upward with the rotation axis of the lever arm 2 as the axis, thereby causing the monitoring gear 31 to rotate relative to the positioning seat 3, forming a rotation angle that can be observed and recorded by the staff.

[0035] Among them, since the distance between the mounting seat 10 and the rotation axis of the lever arm 2 is smaller than the distance between the arc-shaped rack 20 and the rotation axis of the lever arm 2, the small-distance settlement of the pile foundation will be converted into the rotation of the monitoring gear 31 in a large angle range for human observation.

[0036] In the above process, since the distance between the positioning seat 3 and the pile foundation settlement area is relatively far, the area where the positioning seat 3 is located is usually not affected by the pile foundation settlement; however, since the distance between the positioning seat 3 and the pile foundation settlement area is relatively close, the positioning seat 3 usually undergoes different degrees of settlement synchronously with the settlement of the pile foundation. When this settlement phenomenon occurs, in order to avoid its impact on the pile foundation settlement monitoring results, the support structure 5 can be first adjusted to make the swing member 4 and the lever arm 2 close to the initial position to eliminate the impact caused by the settlement.

[0037] Compared with the prior art, the pile foundation settlement monitoring device provided in this embodiment can monitor the settlement phenomenon of the pile foundation through a mechanical structure, reduce errors, and improve the reliability of the monitoring results.

[0038] In some embodiments, Figure 5 , Fig. 9 and Fig.10 As shown, the base 1 has an upwardly extending column 11, and the upper end of the column 11 has a first spherical member 111; the lower end of the swing member 4 is connected to a support plate 41, the lower side of the support plate 41 has a protrusion 411, and the extended end surface of the protrusion 411 has a first concave ball groove 412, the first spherical member 111 is embedded in the first concave ball groove 412 to form a ball hinge relationship, so that the swing member 4 can swing with multiple degrees of freedom relative to the base 1.

[0039] The first spherical member 111 is made of an elastic material, and / or the protrusion 411 is made of an elastic material, so that the distance between the base 1 and the swing member 4 can be adjusted to a certain extent, thereby eliminating the aforementioned position error.

[0040] Based on this, the aforementioned supporting structure 5 includes a turntable 51 and two linear cylinders 52 .

[0041] The turntable 51 is coaxially sleeved on the outer periphery of the column 11 and is transmission-connected to a rotation driving member 6 for driving the turntable 51 to rotate.

[0042] The two linear cylinders 52 are fixedly arranged on the upper side of the turntable 51, and are symmetrically arranged with the column 11 as the axis; before adjusting the two linear cylinders 52, it is necessary to rotate the rotating driving component 6 so that the arrangement direction of the two linear cylinders 52 and the projection direction of the tilt direction of the turntable 51 are in the same direction.

[0043] The power output axis of each linear cylinder 52 is parallel to the axis of the column 11, and the power output end of each linear cylinder 52 is connected to the support plate 41. It should be supplemented that the lower side of the support plate 41 has an annular guide rail, and the lower side of the guide rail has an annular annular groove suitable for the power output end of the linear cylinder 52 to be embedded.

[0044] In actual use, by adjusting the extension amount of the two linear cylinders 52 (i.e., controlling the cylinder shaft of one linear cylinder 52 to extend and the cylinder shaft of the other linear cylinder 52 to retract), the length direction of the swing member 4 can be directed toward the initial position of the swing member 4 and the rotation axis of the lever arm 2; on this basis, by synchronously adjusting the extension amount of the two linear cylinders 52 (i.e., controlling the cylinder shafts of the two linear cylinders 52 to extend or retract synchronously), the rotation axis of the swing member 4 and the lever arm 2 can be returned to the initial position to achieve the technical purpose of eliminating position errors. In actual use, this technical step can be selectively implemented according to engineering needs.

[0045] In some embodiments, Fig. 9 and Fig.10 As shown, a plurality of tooth grooves 511 are provided on the outer peripheral wall of the turntable 51 and are spaced apart along the circumference thereof. Based on this, the aforementioned rotation driving component 6 includes a rotation motor 61 and a transmission gear 62 .

[0046] The rotating motor 61 is fixedly mounted on the base 1, and its power output axis is parallel to the axis of the support plate 41; in this embodiment, a sinking groove is provided on the upper side of the base 1, and the rotating motor 61 is fixedly embedded in the sinking groove.

[0047] The transmission gear 62 is fixedly connected to the power output end of the rotating motor 61, and its tooth end is meshed with the tooth groove 511, so that when the rotating motor 61 is started, the transmission gear 62 drives the turntable 51 to rotate synchronously, thereby changing the position of the two linear cylinders 52 relative to the base 1, so as to adjust the inclination angle of the support plate 41 by controlling the extension amount of the two linear cylinders 52.

[0048] In some embodiments, Figure 4 and Figure 5 As shown, a protective shell 12 is placed on the base 1. The protective shell 12 is covered on the outside of the support plate 41 and is arranged around the swing member 4 to avoid interference with the adjustment of the swing member 4 on the one hand, and to prevent rain, dust and other impurities from falling in to a certain extent on the other hand.

[0049] In some embodiments, Fig.11 and Fig.14 As shown, the swing member 4 has a mounting platform 7 and an infrared receiving board 8 spaced apart along the length direction thereof. After the swing member 4 is fixed, the mounting platform 7 is located above the infrared receiving board 8 .

[0050] Based on this, the aforementioned mounting platform 7 further includes a second concave ball groove 71 , a second spherical member 72 and an infrared emitter 9 .

[0051] The second concave ball groove 71 is formed on the side of the mounting platform 7 facing the infrared receiving plate 8 , and the second ball-shaped member 72 is embedded in the second concave ball groove 71 .

[0052] The infrared transmitter 9 is arranged between the mounting platform 7 and the infrared receiving board 8 , and is connected to the second spherical member 72 via a pull rope 91 .

[0053] Among them, a plurality of coaxially arranged and annular indicating parts 81 are provided on the infrared receiving board 8; when the length direction of the swinging member 4 is parallel to the up-down direction, the pull rope 91 is suitable to be in a drooping state in which its length direction is parallel to the up-down direction, and the infrared light of the infrared transmitter 9 is projected onto the center of the indicating part 81.

[0054] When the base 1 tilts due to settlement, the distance between the infrared transmitter 9 and the infrared receiving plate 8 changes, and the distance between the infrared light projected by the infrared transmitter 9 and the center of the indicator 81 changes synchronously; when the swing member 4 needs to be adjusted, the above two change values ​​can be converted into adjustment data feedback to realize automatic adjustment of the swing member 4 under system control.

[0055] In some embodiments, Figures 11 to 13 As shown, the swing member 4 has a plurality of positioning holes 42 spaced apart along its length direction, and the mounting platform 7 is provided with a positioning hole 73 suitable for communicating with any one of the positioning holes 42 .

[0056] Based on this, the mounting platform 7 also includes an insertion shaft 74, which is suitable for being inserted into the mutually connected positioning hole 42 and alignment hole 73. One end of the insertion shaft 74 has an anti-detachment portion 741 extending outward, and the other end has an anti-detachment bolt 742 threadedly connected to its end face.

[0057] In some embodiments, Figure 6 and Figure 7 As shown, a receiving groove 201 suitable for inserting the lever arm 2 is provided on the side of the arc-shaped rack 20 facing away from the monitoring gear 31, and a mounting hole 202 is provided on the arc-shaped rack 20, which is connected to the receiving groove 201 and passes through along the thickness direction thereof.

[0058] The lever arm 2 is provided with a docking hole 21 communicating with the mounting hole 202 , and the lever arm 2 further includes a connecting bolt 22 .

[0059] The connecting bolt 22 is suitable for being inserted into the interconnected docking hole 21 and the mounting hole 202; the connecting bolt 22 has a head that abuts against the outer side of the arc-shaped rack 20, and the connecting bolt 22 is transmission-connected with a connecting nut 221 suitable for abutting against the other side of the arc-shaped rack 20, so as to facilitate the installation and removal of the arc-shaped rack 20 on the lever arm 2.

[0060] In some embodiments, Figure 2 and Figure 6As shown, the mounting seat 10 is hinged to the lever arm 2, so that when the bottom surface of the mounting seat 10 is connected to the pile foundation, the lever arm 2 is suitable for being tilted to facilitate the assembly of the device.

[0061] In some embodiments, Figure 8 As shown, the positioning seat 3 has a mounting shaft 32 extending in the horizontal direction, and the mounting shaft 32 is parallel to the rotation axis of the lever arm 2. The aforementioned monitoring gear 31 is sleeved on the mounting shaft 32, and the positioning seat 3 also has an arc hole 33 extending around the mounting shaft 32 and coinciding with the side of the monitoring gear 31.

[0062] Based on this, the monitoring gear 31 has an indicating shaft 311 inserted into the arc hole 33 , and the outer side surface of the positioning seat 3 is provided with a scale mark 34 surrounding the installation shaft 32 and arranged outside the arc hole 33 .

[0063] In actual use, the rotation angle of the monitoring gear 31 can be obtained by observing the relative positions of the indicating shaft 311 and the scale mark 34 .

[0064] In some embodiments, Figure 2 and Figure 4 As shown, the pile foundation settlement monitoring device further includes a plurality of reinforcement piles 30 .

[0065] A plurality of reinforcement piles 30 are used to be fixed on the ground between the base 1 and the positioning seat 3, and are arranged at intervals along the direction from the base 1 to the positioning seat 3; each reinforcement pile 30 has a convex portion 301, and the convex portion 301 is also made of elastic material to avoid interfering with the sinking of a part of the upper area of ​​the lever arm 2 (due to the settlement of the base 1).

[0066] In actual use, the round convex portion 301 abuts against the lower side of the lever arm 2 to support the lever arm 2 and reduce fatigue damage to the lever arm 2 when no pile foundation settlement occurs.

[0067] The above content is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
