Description

Technical Field

[0001] This utility model relates to the field of geological surveying equipment technology, and in particular to an inclinometer. Background Technology

[0002] Sliding inclinometers are widely used in various applications such as landslide prevention, construction monitoring, and dam maintenance to monitor deep subsurface displacement and deformation.

[0003] In related technologies, the inclinometer rod of a sliding inclinometer is equipped with an inclined guide wheel. When the inclinometer rod is pulled into the inclined tube by a rope, the guide wheel is prone to large deviations in tilt angle due to the tensile force, resulting in large measurement errors.

[0004] Therefore, a new inclinometer is needed to solve the above problems. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model aims to provide an inclinometer with large tilt deviation and high measurement accuracy.

[0006] The technical solution of this utility model is implemented as follows:

[0007] An inclinometer includes an inclinometer rod and a guide wheel assembly assembled on the inclinometer rod. The guide wheel assembly includes a guide wheel frame sleeved on the inclinometer rod, a set of positioning wheels and two sets of movable wheels assembled on the guide wheel frame. The positioning wheels and the movable wheels are arranged perpendicularly to the longitudinal direction of the inclinometer rod on opposite sides. The two sets of movable wheels are symmetrically arranged about the center line of the guide wheel frame, with the center line of the guide wheel frame as the axis of symmetry.

[0008] Preferably, the guide wheel frame includes a sleeve fitted on the inclinometer rod, an upper bracket and a lower bracket fixed on the sleeve, the positioning wheel is mounted on the upper bracket, and the movable wheel includes a support frame hinged to the lower bracket and a guide wheel mounted on the support frame at the end away from the lower bracket.

[0009] Preferably, the upper support and the lower support are formed on opposite sides in the vertical direction of the longitudinal direction of the inclinometer rod.

[0010] Preferably, the guide wheel is mounted on the support frame via a pin.

[0011] Preferably, the two sets of movable wheels are distributed in a figure-eight shape.

[0012] Preferably, the inclinometer rod has a plurality of positioning holes spaced apart along the longitudinal direction of the inclinometer rod, and the guide wheel frame can be positioned on different positioning holes by means of fasteners.

[0013] Preferably, the fastener is a bolt.

[0014] Preferably, the inclinometer rod is a hollow steel pipe.

[0015] Preferably, the guide wheel frame is made of plastic and is integrally molded.

[0016] Preferably, there are two guide wheel assemblies, which are respectively fixed at both ends of the inclinometer rod.

[0017] The inclinometer provided in this embodiment of the utility model has a positioning wheel and a movable wheel set vertically along the longitudinal direction of the inclinometer rod. This allows the positioning wheel of the inclinometer to be close to the groove of the tube when it enters the inclinometer tube, and the movable wheel to be close to the tube wall. At the same time, the two sets of movable wheels provide bidirectional support, which can support the inclinometer more stably in the tube without deviation or tilting, making the test data more accurate and true.

[0021] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Please see Figure 1 and Figure 2This invention provides an inclinometer. The inclinometer includes an inclinometer rod 1 and a guide wheel assembly 3 assembled on the inclinometer rod 1. The guide wheel assembly 3 includes a guide wheel frame 31 sleeved on the inclinometer rod 1, and a set of positioning wheels 33 and two sets of movable wheels 35 assembled on the guide wheel frame 31. The positioning wheels 33 and the movable wheels 35 are arranged perpendicularly to the longitudinal direction of the inclinometer rod 1 on opposite sides. The two sets of movable wheels 35 are symmetrically arranged about the center line of the guide wheel frame 31, opening in opposite directions. When the inclinometer enters the inclined tube, the positioning wheels 33 are pressed against the tube groove, and the movable wheels 35 are pressed against the tube wall, sliding along the inclined tube. During the sliding process, the two sets of movable wheels 35 provide bidirectional support, providing more stable support inside the tube without deviation or tilting, resulting in more accurate and reliable test data.

[0023] Specifically, in this embodiment, the guide wheel frame 31 includes a sleeve 311 sleeved on the inclinometer rod 1, an upper bracket 313 and a lower bracket 315 fixed on the sleeve 311. The positioning wheel 33 is mounted on the upper bracket 313. The movable wheel 35 includes a support frame 357 hinged to the lower bracket 315 and a guide wheel 353 mounted on the end of the support frame 357 away from the lower bracket 315. The support frame 357 is connected to the lower bracket 315 by a pin and a torsion spring, so that the support frame 357 can be adjusted by changing its angle under the action of external force while maintaining a certain preset angle. This can effectively lift the guide wheel, making it more closely fit the wall of the inclinometer tube, and making the test data more accurate.

[0024] Furthermore, the upper support 313 and the lower support 315 are formed on opposite sides of the longitudinal direction of the inclinometer rod 1. The upper support 313 and the lower support 315 support the positioning wheel 33 and the movable wheel 35 inside the inclinometer tube from opposite directions, so that the inclinometer rod 1 can maintain the same inclination angle with the inclinometer tube, thereby further improving the testing accuracy.

[0025] Furthermore, the guide wheel 353 is mounted on the support frame 357 via a pin. The guide wheel 353 rotates on the support frame 357, allowing the inclinometer rod 1 to slide up and down within the inclinometer tube.

[0026] In detail, the two sets of movable wheels 35 are distributed in a figure-eight shape. That is, the movable wheels 35 are spread out in two directions to form bidirectional support, thereby improving the stability of the support.

[0027] like Figure 3As shown, the guide wheel assembly 3 is distributed at both ends of the inclinometer rod 1, and the movable wheel 35 and the positioning wheel 33 are installed in different directions. Several positioning holes 11 are spaced apart along the longitudinal direction of the inclinometer rod 1 at both ends. The guide wheel frame 31 can be positioned in different positioning holes 11 by fasteners, allowing the guide wheel frame 31 to be adjusted in position. Therefore, by providing positioning holes 11 on the inclinometer rod 1, the guide wheel frame 31 can be installed at different positions at both ends of the inclinometer rod 1, allowing for adjustment according to different inclinometer tubes, thereby improving the applicability of the inclinometer.

[0028] Specifically, the fastener is a bolt. The bolt passes through the guide wheel bracket 31 and is fixed in the positioning hole to assemble it onto the inclinometer rod 1 to form a connection.

[0029] Specifically, the inclinometer rod 1 is a hollow steel pipe, which has high strength and light weight.

[0030] Specifically, in this embodiment, the guide wheel frame 31 is made of plastic and is integrally molded, making the manufacturing process simpler.

[0031] The inclinometer provided in this embodiment of the utility model is configured with positioning wheels 33 and movable wheels 35 arranged vertically along the longitudinal direction of the inclinometer rod 1. This allows the positioning wheels 33 of the inclinometer to be close to the groove of the tube when it enters the inclinometer tube, and the movable wheels 35 to be close to the tube wall. At the same time, the two sets of movable wheels 35 provide bidirectional support, which can more stably support the inclinometer inside the tube without deviation or tilting, making the test data more accurate and true.

[0032] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
