Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of inclinometer, and particularly relates to an adjustable inclinometer. BACKGROUND

[0002] In geotechnical engineering, an inclinometer needs to be used to monitor the deep horizontal displacement of a foundation pit, so as to control the excavation rate of the foundation pit and determine whether the slope of the foundation pit needs to be reinforced.

[0003] In the prior art, the inclinometer is usually used in combination with an inclinometer tube, specifically, the inclinometer tube is fixed in the installation position by a drilling and embedding method or a binding and embedding method, the inclinometer enters from the upper end opening of the inclinometer tube, moves upward to exit the inclinometer tube after falling to the lower end of the inclinometer tube, and the inclination angle of the axis of the inclinometer tube relative to the plumb line is measured by the sensor in the inclinometer in the process.

[0004] The inventor finds that after the inclinometer tube is placed in the drill hole, grouting needs to be performed between the inclinometer tube and the drill hole to ensure the stability of the installation of the inclinometer tube. In general, the inclinometer tube needs to be selected in a size suitable for the drill hole to avoid the situation that excessive slurry solidification causes extrusion and damage to the inclinometer tube; however, due to the error in the drilling operation, sometimes it is necessary to select an inclinometer tube that is not suitable for the predetermined inclinometer, and at this time, the inclinometer cannot be used because the rollers thereof cannot stably contact the inner wall of the inclinometer tube, which causes the inclinometer operation to be unable to proceed smoothly and reduces the reliability of the inclinometer result.

Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the application, the meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0045] Please refer to Figures 1 to 9 , now the adjustable inclinometer provided by the application will be described. The adjustable inclinometer provided by the application includes a measuring rod 1 for insertion into an inclinometer tube.

[0046] The measuring rod 1 is provided with at least two mounting holes 11 spaced along its axial direction, each mounting hole 11 penetrates along the radial direction of the measuring rod 1, and the axial directions of every two mounting holes 11 are parallel to each other. Each measuring rod 1 is provided with a pulley set, and the pulley set includes a partition plate 2 and two pulley bodies 3.

[0047] The partition plate 2 is arranged in the mounting hole 11, and between the partition plate 2 and the measuring rod 1 there is a limiting structure 4 for limiting the movement of the partition plate 2. Specifically, the outer peripheral wall of the partition plate 2 and the inner peripheral wall of the mounting hole 11 are connected to divide the mounting hole 11 into two parts which are parallel and independent along the axial direction of the mounting hole 11.

[0048] The two pulley bodies 3 are arranged side by side along the axial direction of the mounting hole 11 on both sides of the partition plate 2, and each pulley body 3 has a distance adjusting structure 5 with the partition plate 2. Each pulley body 3 is perpendicular to the axial direction of the mounting hole 11 and perpendicular to the axial direction of the measuring rod 1, so as to extend out of the mounting hole 11 and contact the inner wall of the inclinometer tube.

[0049] In the embodiment, the limiting structure 4 limits the movement of the partition plate 2, so as to ensure the stable arrangement of the pulley block; based on this, the distance adjusting structure 5 is used to adjust the distance between the pulley body 3 and the partition plate 2, so as to ensure that each pulley body 3 is in contact with the inner wall of the inclinometer casing when the measuring rod 1 is inserted into the inclinometer casing, and the coaxial or eccentric arrangement of the measuring rod 1 and the inclinometer casing.

[0050] Compared with the prior art, the adjustable inclinometer provided in the embodiment can be flexibly adapted to inclinometer casings of different sizes, so as to ensure the smooth performance of the inclining operation and the reliability of the inclining result.

[0051] In some embodiments, as shown in Figure 2 and Figure 3 , the distance adjusting structure 5 includes two sliding blocks 51 and two swing arms 52.

[0052] The two sliding blocks 51 are arranged side by side in the up-down direction on the side of the partition plate 2 axially facing the mounting hole 11, and each sliding block 51 is in sliding connection with the partition plate 2 in the axial direction of the measuring rod 1.

[0053] The two swing arms 52 are arranged on the two sliding blocks 51 respectively, and one end of each swing arm 52 is hinged to the sliding block 51, and the other end is hinged to the pulley body 3; wherein the hinged axes corresponding to the two ends of the swing arm 52 are parallel to each other, and are parallel to the axial direction of the pulley body 3.

[0054] By adopting the above technical solution, when the two sliding blocks 51 move towards each other or move away from each other, the two swing arms 52 swing synchronously, and the pulley body 3 moves towards or away from the partition plate 2, so as to achieve the technical purpose of adjusting the distance between the pulley body 3 and the partition plate 2.

[0055] In some embodiments, as shown in Figure 2 and Figure 4 , two guide grooves 21 are formed on the two sides of the partition plate 2 axially facing the mounting hole 11, which are arranged side by side in the up-down direction and are adapted for embedding the two sliding blocks 51 on the same side, so as to realize the sliding connection between the sliding block 51 and the partition plate 2, and limit the sliding direction of the sliding block 51.

[0056] In some embodiments, as shown in Figures 2 to 4 , the partition plate 2 has two reserved holes 22 arranged side by side in the axial direction of the mounting hole 11; each reserved hole 22 is arranged in the axial direction of the measuring rod 1 and communicates with the two guide grooves 21 on the same side; specifically, in the embodiment, the reserved hole 22 penetrates from the end of the partition plate 2 to the bottom surface of the guide groove 21 away from the end.

[0057] Each reserved hole 22 is inserted with a double-headed screw 23, and the double-headed screw 23 has two threaded parts with opposite screw directions; the two threaded parts are respectively located in the two guide grooves 21 and are in threaded connection with the two sliding blocks 51.

[0058] By adopting the technical scheme, when the double-headed screw 23 rotates, the two sliding blocks 51 can move towards or away from each other synchronously, so that the pulley body 3 moves towards or away from the partition plate 2.

[0059] In some embodiments, as shown in Figure 2 , Figure 7 and Figure 8 , the partition plate 2 is fixedly provided with a rotating motor 6; the rotating motor 6 is between the two double-headed screws 23, and the power output shaft of the rotating motor 6 is parallel to the axial direction of the double-headed screws 23.

[0060] Each double-headed screw 23 is coaxially connected with a driven gear 20, and the power output shaft of the rotating motor 6 is coaxially connected with a driving gear 10 engaged with the two driven gears 20, so that when the rotating motor 6 is started, each double-headed screw 23 rotates synchronously under the transmission relationship between the driving gear 10 and the corresponding driven gear 20, so as to adjust the movement of the corresponding two sliding blocks 51 towards or away from each other, and the movement of the pulley body 3 towards or away from the partition plate 2.

[0061] By adopting the technical scheme, when the measuring rod 1 is in the inclinometer tube underground, the rotating motor 6 is remotely controlled to ensure that each pulley body 3 abuts against the inner wall of the inclinometer tube and is adaptively adjusted according to different pipe diameters.

[0062] In some embodiments, as shown in Figure 2 , Figure 7 and Figure 8 , the end of the partition plate 2 has a sinking groove 24 suitable for embedding the rotating motor 6, and an end cover 7 connected thereto.

[0063] The power output end of the rotating motor 6 has a protruding portion 61 extending radially outward therefrom, and the driving gear 10 is sleeved on the power output shaft of the rotating motor 6 and connected with the protruding portion 61.

[0064] In actual use, the driving gear 10 is sleeved on the power output shaft of the rotating motor 6, so that the transmission connection between the rotating motor 6 and the driving gear 10 is realized by the structural design of the protruding portion 61; when any one of the double-headed screws 23 needs to be adjusted, the driving gear 10 can be removed for adjustment without interfering with the other double-headed screw 23.

[0065] Furthermore, when the end cover 7 is connected with the partition plate 2, the inner side of the end cover 7 abuts against the driving gear 10 to limit the movement of the driving gear 10 away from the rotating motor 6, thereby ensuring the stability of the connection relationship between the driving gear 10 and the rotating motor 6.

[0066] In some embodiments, as shown in Figure 7 andFigure 8 As shown, the partition 2 has a positioning screw 25 extending toward the end cover 7; based on this, the end cover 7 is provided with an alignment hole 71 suitable for the positioning screw 25 to pass through, and is also provided with a mating nut 72 that is threadedly connected to the positioning screw 25 and abuts against the end cover 7.

[0067] In some embodiments, such as Figure 5 As shown, the drive gear 10 is provided with a plurality of balls 101 on the side facing the end cover 7, which are suitable for rolling relative to the drive gear 10. The end cover 7 is provided with an annular groove 73 surrounding the power output shaft of the rotating motor 6, which is suitable for the balls 101 to be embedded in, so as to ensure the smooth rotation of the drive gear 10 relative to the end cover 7 while keeping the drive gear 10 in contact with the end cover 7.

[0068] In some embodiments, such as Figure 9 As shown, the limiting structure 4 includes two threaded grooves 41 and two stop blocks 42.

[0069] Both threaded grooves 41 are opened on the inner wall of the mounting hole 11 facing the measuring rod 1, and are arranged side by side on both sides of the partition plate 2 along the axial direction of the mounting hole 11.

[0070] Two actuating blocks 42 are respectively disposed on both sides of the partition 2 facing the mounting hole 11 axially, and both abut against the partition 2, thereby clamping the partition 2 and restricting the movement of the partition 2.

[0071] Each of the actuating blocks 42 has a positioning hole 421 that extends through the measuring rod 1 along the axial direction, and a mating bolt 422 suitable for threaded connection with the threaded groove 41 is inserted into the positioning hole 421 to limit the movement of the actuating block 42 relative to the measuring rod 1.

[0072] In some embodiments, such as Figure 9 As shown, the actuating block 42 is provided with a groove 4211 on the side facing the measuring rod 1, which is coaxially connected with the positioning hole 421 and suitable for the head of the mating bolt 422 to be inserted, so as to realize the hidden arrangement of the mating bolt 422.

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.
