Description

Technical Field

[0001] This application belongs to the field of engineering testing technology, specifically relating to a fixed base for detecting ground tilt. Background Technology

[0002] Ground tilt detection is crucial in fields such as construction, engineering, and geological monitoring. Its purpose is to determine the tilt value of the ground (or building surface) to ensure project quality.

[0003] The existing method for detecting ground tilt involves marking two points on the ground and installing levels at these points. The height difference and distance between the two points are then calculated from the readings of the two levels, and the ground tilt is determined accordingly. To enhance the reliability of the detection results, multiple sets of points are typically used during the ground tilt detection process. Specifically, one point is fixed, while another point is selected at the same or different distances.

[0004] The inventors discovered that the existing level instrument base has a simple structure, which has technical defects such as low efficiency and large error when adjusting its position, resulting in increased error in the ground tilt result and loss of the original comparison effect. Utility Model Content

[0005] This application provides a fixed base for ground tilt detection, which aims to efficiently and stably adjust the relative position of two levels to ensure the reliability of the detection results.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0007] A fixed base for detecting ground tilt is provided, comprising a positioning seat and an alignment seat arranged side-by-side on the ground, wherein the positioning seat is fixedly mounted on the ground and the alignment seat is slidably mounted on the ground; the fixed base further comprises:

[0008] A slide table is slidably disposed on the positioning seat along the circumference of the positioning seat;

[0009] A rotating roller, rotatably connected to the slide, is arranged axially and in the same direction as the rotation axis and both are parallel to the horizontal direction; and

[0010] A ranging belt has one end fixedly connected to the rotating roller so that when the rotating roller rotates, the ranging belt wraps around the rotating roller or detaches from the rotating roller; and the other end of the ranging belt is connected to the alignment seat so that when the alignment seat rotates around the positioning seat, the slide slides synchronously, and when the alignment seat moves away from or toward the positioning seat, the rotating roller rotates synchronously.

[0011] In one possible implementation, the upper side of the positioning seat has an annular groove coaxially arranged therewith, and the slide table further includes:

[0012] A connecting rod is fixedly connected to the bottom surface of the slide and inserted into the annular groove so that the slide and the positioning seat are slidably connected, and the slide can rotate relative to the positioning seat about the connecting rod as an axis.

[0013] In one possible implementation, one end of the rotating roller has a turntable extending radially outward therefrom, the outer peripheral wall of the turntable having a plurality of grooves spaced circumferentially thereon, and the slide table further includes:

[0014] An insert is slidably disposed on the slide table, and an elastic element is provided between it and the slide table;

[0015] The elastic element can drive the insert to move toward the turntable, so that the insert can be inserted into any of the grooves to restrict the rotation of the turntable.

[0016] In one possible implementation, the elastic element includes:

[0017] A fixing plate is fixedly mounted on the slide table and located on the side of the insert facing away from the turntable; and

[0018] A spring is disposed between the fixed plate and the insert, and its two ends are respectively connected to the fixed plate and the insert;

[0019] When the insert is inserted into any of the grooves, the spring is in an elastically compressed state or its original length state; when the insert moves away from the turntable to disengage from the groove, the spring is in an elastically compressed state to facilitate moving the insert toward the turntable.

[0020] In one possible implementation, the insert has an anti-bend rod adapted to be inserted into the spring, pass through the fixing plate, and extend outwards.

[0021] In one possible implementation, both the positioning seat and the alignment seat have radially outwardly extending extensions at their bottoms for support on the ground.

[0022] In one possible implementation, the outer peripheral wall of the positioning seat is provided with a plurality of strip grooves spaced apart along its circumference, each of the strip grooves extending in the vertical direction and fitted with a lifting platform suitable for sliding relative to the positioning seat.

[0023] The lifting platform is fixedly connected to a downwardly extending fixing pile, which is located outside the outer extension or is installed through the outer extension for insertion into the ground from top to bottom.

[0024] In one possible implementation, the upper end face of the positioning seat has multiple through holes that correspond one-to-one with the multiple strip slots, and each of the lifting platforms has a mounting nut coaxially arranged with the through holes; the lifting platform further includes:

[0025] A limiting bolt, adapted to be inserted into the through hole and threadedly connected to the mounting nut, restricts the movement of the lifting platform relative to the positioning seat.

[0026] In one possible implementation, the ranging band has a through hole extending along its thickness direction; and the positioning seat has a connecting block, the outer side of the connecting block having a reserved groove suitable for inserting the end of the ranging band, and the upper end face of the connecting block having a mating hole suitable for communicating with the through hole.

[0027] The connecting block also includes:

[0028] A fixing nut is fixedly connected to the upper end face of the connecting block and communicates with the mating hole; and

[0029] An anti-loosening bolt, threaded onto the fixing nut, is adapted to pass through the mating hole and be inserted into the through hole to prevent the ranging band from disengaging from the reserved slot.

[0030] In one possible implementation, the inner bottom surface of the reserved groove is provided with a recessed groove that is coaxially arranged with the docking hole and is suitable for the insertion of the anti-loosening bolt.

[0031] In this embodiment, two levels are installed by fixing them to the upper surfaces of the positioning base and the alignment base, respectively. Based on this, the relative positions of the two levels can be adjusted by fixing the positioning base to the ground and moving the alignment base relative to the positioning base.

[0032] When it is necessary to fix the distance between two levels, the operator can control the winding and unwinding of the measuring tape relative to the rotating roller, and observe and determine the distance between the two levels simply by moving the slide table relative to the positioning seat.

[0033] When it is necessary to extend or shorten the distance between two levels, the operator can control the rotation of the rotating roller to either wrap the measuring tape around the roller or detach it from the roller, thus adapting the two levels with different distances.

[0034] The ground tilt detection base provided in this embodiment can efficiently and stably adjust the relative position of two levels compared with the prior art, ensuring the reliability of the detection results. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0048] Please refer to the following: Figures 1 to 7 The fixed base for ground tilt detection provided in this application will now be described. The fixed base for ground tilt detection proposed in this application includes a positioning seat 1, an alignment seat 2, a slide table 3, a rotating roller 4, and a measuring belt 5.

[0049] The positioning seat 1 and the alignment seat 2 are arranged side by side on the ground, with the positioning seat 1 fixedly mounted on the ground and the alignment seat 2 slidably mounted on the ground. In actual use, the two levels are fixedly mounted on the positioning seat 1 and the alignment seat 2 respectively, and are located on the upper end face of the positioning seat 1 and the upper end face of the alignment seat 2.

[0050] The slide table 3 is slidably disposed on the positioning seat 1 along the circumference of the positioning seat 1, specifically disposed on the upper end surface of the positioning seat 1.

[0051] The rotating roller 4 is rotatably connected to the slide table 3, and its axial direction and rotation axis are set in the same direction and are both parallel to the horizontal direction.

[0052] The ranging band 5 is made of a flexible, non-stretchable material and is positioned between the positioning seat 1 and the alignment seat 2. Specifically:

[0053] One end of the ranging belt 5 is fixedly connected to the rotating roller 4 so that when the rotating roller 4 rotates, the ranging belt 5 either wraps around the rotating roller 4 or detaches from the rotating roller 4.

[0054] The other end of the measuring belt 5 is connected to the alignment seat 2 so that when the alignment seat 2 rotates around the positioning seat 1, the slide table 3 slides synchronously, and when the alignment seat 2 moves away from or toward the positioning seat 1, the rotating roller 4 rotates synchronously.

[0055] In this embodiment, two levels are fixed to the upper surfaces of positioning base 1 and alignment base 2 respectively, thus enabling the installation of the two levels. Based on this, by fixing positioning base 1 to the ground and moving alignment base 2 relative to positioning base 1, the relative positions of the two levels can be adjusted.

[0056] When it is necessary to fix the distance between two levels, the staff can control the winding and unwinding of the measuring belt 5 relative to the rotating roller 4, and observe and determine the distance between the two levels simply by moving the slide table 3 relative to the positioning seat 1.

[0057] When it is necessary to extend or shorten the distance between two levels, the operator can control the rotating roller 4 to rotate, so that the measuring tape 5 can be wound around the rotating roller 4 or detached from the rotating roller 4, thereby adapting to two levels with different distances.

[0058] The ground tilt detection base provided in this embodiment can efficiently and stably adjust the relative position of two levels compared with the prior art, ensuring the reliability of the detection results.

[0059] In some embodiments, such as Figure 2 and Figure 3 As shown, the upper side of the positioning seat 1 is provided with an annular groove 11 coaxially arranged therewith. Based on this, the slide table 3 also includes a connecting rod 31.

[0060] The connecting rod 31 is fixedly connected to the bottom surface of the slide table 3 and inserted into the annular groove 11 so that the slide table 3 and the positioning seat 1 are slidably connected. The slide table 3 can rotate relative to the positioning seat 1 with the connecting rod 31 as the axis, thereby changing the orientation of the rotating roller 4 and ensuring that the measuring belt 5 remains horizontal and taut.

[0061] It should be noted that in this embodiment, the annular groove 11 adopts an inverted T-shaped structure, and the lower end of the connecting rod 31 has a disc portion that is embedded in the bottom of the annular groove 11.

[0062] In some embodiments, such as Figure 3 and Figure 4 As shown, one end of the rotating roller 4 has a turntable 41 extending radially outward. The outer peripheral wall of the turntable 41 is provided with a plurality of grooves 411 spaced apart along its circumference, and each groove 411 is through the thickness direction of the turntable 41.

[0063] Based on this, the slide table 3 also includes a connector 32, which is slidably disposed on the slide table 3 and has an elastic member 6 between it and the slide table 3.

[0064] In actual use, the elastic element 6 can drive the insert 32 to move toward the turntable 41, so that the insert 32 can be inserted into any of the grooves 411 to restrict the rotation of the turntable 41.

[0065] In some embodiments, such as Figure 4 As shown, the elastic element 6 includes a fixed plate 61 and a spring 62.

[0066] The fixing plate 61 is fixedly mounted on the slide table 3 and is located on the side of the insert 32 facing away from the turntable 41.

[0067] Spring 62 is disposed between fixed plate 61 and insert 32, and its two ends are connected to fixed plate 61 and insert 32 respectively.

[0068] When the insert 32 is inserted into any of the grooves 411, the spring 62 is in an elastic compression state or in its original length state; where the original length state refers to the state in which the spring 62 has not deformed.

[0069] When the insert 32 moves away from the turntable 41 and disengages from the groove 411, the spring 62 is in an elastically compressed state, so as to drive the insert 32 toward the turntable 41 without external force.

[0070] In some embodiments, such as Figure 4 As shown, the insert 32 has an anti-bending rod 321 that is suitable for inserting the spring 62, passing through the fixing plate 61 and extending out. This anti-bending rod 321 serves to limit the bending deformation of the spring 62 and also serves to realize the sliding connection between the insert 32 and the slide table 3.

[0071] In some embodiments, such as Figure 1 As shown, both the positioning seat 1 and the alignment seat 2 have an extension 10 extending radially outward at their bottoms for support on the ground, in order to increase the contact area and ensure the stability of the positioning seat 1 and the alignment seat 2 on the ground, and to more intuitively reflect the degree of inclination of the ground.

[0072] In some embodiments, such as Figure 1 and Figure 6 As shown, the outer peripheral wall of the positioning seat 1 is provided with a plurality of strip grooves 12 spaced apart along its circumference. Each strip groove 12 extends in the vertical direction and is fitted with a lifting platform 7 suitable for sliding relative to the positioning seat 1.

[0073] Based on this, a downwardly extending fixing stake 71 is also fixedly connected to the lifting platform 7. This fixing stake 71 is located on the outside of the extension 10 or is provided through the extension 10, so as to be inserted into the ground from top to bottom, thereby fixing the position of the positioning seat 1 relative to the ground.

[0074] In some embodiments, such as Figure 6 As shown, the upper end face of the positioning seat 1 is provided with a plurality of through holes 13 that correspond one-to-one with a plurality of strip grooves 12, and each lifting platform 7 is provided with an installation nut 72 coaxially arranged with the through hole 13; based on this, the lifting platform 7 also includes a limit bolt 73.

[0075] The limiting bolt 73 is adapted to be inserted into the through hole 13 and threadedly connected to the mounting nut 72 to limit the movement of the lifting platform 7 relative to the positioning seat 1.

[0076] In some embodiments, such as Figure 7 As shown, the ranging band 5 has a through hole 51 extending along its thickness direction; and the mounting base 2 has a connecting block 8, which has a reserved groove 81 on its outer side facing the horizontal direction for inserting the end of the ranging band 5, and a mating hole 82 on its upper end face for communicating with the through hole 51; based on this, the connecting block 8 also includes a fixing nut 83 and an anti-loosening bolt 84.

[0077] The fixing nut 83 is fixedly connected to the upper end face of the connecting block 8 and communicates with the aforementioned mating hole 82.

[0078] The anti-loosening bolt 84 is threaded onto the fixing nut 83 and is adapted to pass through the mating hole 82 and be inserted into the through hole 51 to prevent the ranging band 5 from disengaging from the reserved slot 81.

[0079] In some embodiments, such as Figure 7 As shown, the inner bottom surface of the reserved groove 81 is provided with a recessed groove 811 that is coaxially arranged with the docking hole 82 and suitable for the insertion of the anti-loosening bolt 84, so as to ensure the limiting effect of the anti-loosening bolt 84 on the ranging band 5.

[0080] The above content is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
