Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit inclinometer equipment, in particular to a guide structure of foundation pit support inclinometer equipment. Background Art

[0002] The foundation pit is an earth pit excavated at the foundation design location according to the base elevation and foundation plane dimensions. After the foundation pit is excavated, supports will be arranged on the side walls of the foundation pit to ensure the safety of underground structure construction and the environment surrounding the foundation pit.

[0003] In order to ensure the smooth construction of foundation pit and foundation pit support, it is necessary to carry out corresponding slope measurement of foundation pit support. In the prior art, inclinometer is often used to measure the slope of foundation pit support. However, since the measuring rod of the inclinometer is only connected to the cable at one end and the other end is suspended in the air, when the measuring rod enters the detection hole of the foundation pit support, it will be difficult to accurately enter the foundation pit support due to shaking, which makes it difficult to carry out the measurement work smoothly. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings, the purpose of the utility model is to provide a guiding structure of a foundation pit support inclinometer, which can guide the movement of the inclinometer rod to ensure that the inclinometer rod enters the foundation pit support quickly and accurately.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is: a guiding structure of a foundation pit support inclinometer, comprising

[0006] A fixed housing is provided with a cable portion for connecting the measuring tilt rod;

[0007] A guide pipe, one end of which is fixedly connected to the fixed housing, and the outer diameter of the other end of which is adapted to the inner diameter of the foundation pit support; a guide channel for accommodating an inclinometer rod is provided in the guide pipe, and the inclinometer rod can slide along the guide channel;

[0008] The locking portion is detachably arranged at one end of the guide tube away from the fixed housing, and is used to lock the inclinometer rod in the guide channel.

[0009] The beneficial effects of the guide structure of the utility model are:

[0010] When in use, first remove the locking part from the guide tube; then insert the end of the guide tube away from the fixed housing into the foundation pit support. Since the outer diameter of this end of the guide tube is matched with the inner diameter of the foundation pit support, the guide tube inserted into the foundation pit support can be stably located in the foundation pit support. At this time, the inclinometer rod located in the guide channel is also located in the foundation pit support; then, by laying out the cable part, the inclinometer rod can move down along the guide channel under the action of gravity until the inclinometer rod moves into the foundation pit support to measure the slope of the foundation pit support.

[0011] By adding a guide tube, the position where the inclinometer rod enters the foundation pit support can be limited. By using the guide tube to guide and limit the inclinometer rod, the shaking of the inclinometer rod during its movement can be suppressed, so that the inclinometer rod can quickly and accurately enter the foundation pit support along the guide tube. In addition, when the inclinometer rod is stored after the measurement, the guide tube can protect the inclinometer rod, and then the inclinometer rod is locked in the guide channel through the locking part, which can prevent the inclinometer rod from moving or even exposing outside the guide tube due to the incorrect laying of the cable part when not in use, thereby improving the safety of the equipment to a certain extent.

[0012] Furthermore, the inclinometer rod includes a rod body and a guide wheel portion; the rod body is coaxially arranged in the guide channel, and the outer diameter of the rod body is smaller than the inner diameter of the guide channel; the guide wheel portion is rotatably arranged on the rod body and can abut against the guide channel.

[0013] Furthermore, the guide channel is provided with a limit guide groove along its length for the guide wheel to abut against. Since the inclinometer rod is in a free-falling state when the cable part is laying out, the limit guide groove can limit the moving direction of the guide wheel part, thereby preventing the inclinometer rod from twisting in the guide channel.

[0014] Furthermore, a trumpet-shaped opening is provided at one end of the guide channel away from the fixed housing.

[0015] It should be noted that, in order to ensure that the guide wheel part is always in contact with the foundation pit support, the length of the rotating shaft of the guide wheel part is greater than the inner diameter of the foundation pit support during the design. This makes the guide wheel part in an inclined state when in the foundation pit support (the rotating shaft is inclined, one guide wheel is in a higher position, and the other guide wheel is in a lower position). In this case, the guide wheel part always has a tendency to rotate; and because the radial dimension of the guide channel is smaller than the inner diameter of the foundation pit support, when the guide wheel part enters the foundation pit support from the guide channel, the guide wheel part will have a certain rotation amplitude. At this time, the setting of the trumpet-shaped opening can slow down the rotation amplitude of the guide wheel part, so that the guide wheel part can enter the foundation pit support more smoothly. In addition, when the inclinometer rod is stored, the guide wheel part can also return to the guide channel along the trumpet-shaped opening.

[0016] Furthermore, an annular boss is coaxially arranged on the outer wall of the guide pipe, and the outer diameter of the annular boss is larger than the inner diameter of the foundation pit support. The annular boss can limit the position of the guide pipe inserted into the foundation pit support, thereby ensuring the stability of the insertion position of the guide pipe.

[0017] Furthermore, the locking portion includes a locking cover that can be sleeved on the guide tube, and the locking cover is provided with a locking slot that can be snapped onto the guide tube.

[0018] Furthermore, a clamping column is provided on the side wall of the guide tube, and the locking slot includes a first groove and a second groove which are arranged vertically and interconnected; the first groove is arranged along the length direction of the guide tube; when the locking cover is put on the guide tube, the clamping column can enter the first groove; when the clamping column enters the junction of the first groove and the second groove, the guide tube or the locking cover is rotated to make the clamping column enter the second groove, thereby realizing the clamping fixation of the locking cover and the guide tube.

[0019] Furthermore, a recessed portion is provided in the middle of the locking cover, which is recessed in the direction of the guide channel; when the locking slot is connected to the guide tube, the recessed portion can abut against the inclinometer rod. The inclinometer rod is stopped by the recessed portion to prevent the inclinometer rod from slipping in the guide channel in the locked state.

[0020] Furthermore, at least one weight-reducing hole communicating with the guide channel is disposed on the side wall of the guide tube.

[0021] Furthermore, a handle is provided on the outer wall of the guide tube to facilitate lifting the inclinometer. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0033] Example

[0034] See attached Figure 1-2 As shown, the utility model is a guiding structure of a foundation pit support inclinometer equipment, comprising a fixed housing 1, a guide pipe 2, and a locking portion 3, wherein the fixed housing 1 is provided with a cable portion (not shown in the figure) for connecting an inclinometer rod 4. One end of the guide pipe 2 is fixedly connected to the fixed housing 1, and the outer diameter of the other end is adapted to the inner diameter of the foundation pit support. A guide channel for accommodating the inclinometer rod 4 is provided in the guide pipe 2, and the inclinometer rod 4 can slide along the guide channel. The locking portion 3 is detachably arranged at one end of the guide pipe 2 away from the fixed housing 1, so as to lock the inclinometer rod in the guide channel.

[0035] When in use, first remove the locking part 3 from the guide tube 2; then insert the end of the guide tube 2 away from the fixed housing 1 into the foundation pit support. Since the outer diameter of this end of the guide tube 2 is matched with the inner diameter of the foundation pit support, the guide tube 2 inserted into the foundation pit support can be stably located in the foundation pit support. At this time, the inclinometer rod 4 located in the guide channel is also located in the foundation pit support; then, by laying out the cable part, the inclinometer rod 4 can move down along the guide channel under the action of gravity until the inclinometer rod 4 moves into the foundation pit support to measure the slope of the foundation pit support.

[0036] By adding a guide tube 2, the position where the inclinometer rod 4 enters the foundation pit support can be limited. By using the guide tube 2 to guide and limit the inclinometer rod 4, the shaking of the inclinometer rod 4 during its movement can be suppressed, so that the inclinometer rod 4 can quickly and accurately enter the foundation pit support along the guide tube 2. In addition, when the inclinometer rod is stored after the measurement, the guide tube 2 can protect the inclinometer rod 4, and then the inclinometer rod 4 can be locked in the guide channel through the locking part 3, which can avoid the inclinometer rod 4 from moving or even exposing outside the guide tube 2 due to the erroneous laying operation of the cable part when not in use, thereby improving the safety of the equipment to a certain extent.

[0037] In some embodiments, see Appendix Figure 2 As shown, an annular boss 21 is coaxially arranged on the outer wall of the guide pipe 2, and the outer diameter of the annular boss 21 is larger than the inner diameter of the foundation pit support. The annular boss 21 can limit the position of the guide pipe 2 inserted into the foundation pit support, ensuring the stability of the insertion position of the guide pipe 2.

[0038] In order to facilitate understanding of the guiding structure of the present application, the structure of the inclinometer rod 4 is described below. Figure 3 As shown, the inclinometer rod 4 generally includes a rod body 41 and a guide wheel portion 42. The rod body 41 is coaxially arranged in the guide channel, and the outer diameter of the rod body 41 is smaller than the inner diameter of the guide channel. The guide wheel portion 42 is rotatably arranged on the rod body 41 and can abut against the guide channel.

[0039] Specifically, a rod body slot for accommodating the guide wheel portion 42 is provided on the rod body 41 along its length direction. The guide wheel portion 42 is located in the rod body slot, and includes a rotating shaft 421 rotatably arranged in the rod body slot, and guide wheels 422 are respectively installed at both ends of the rotating shaft 421. When in use, due to the deadweight of the guide wheels 422, the rotating shaft 421 can rotate until both guide wheels 422 abut against the inner side wall of the guide channel or the foundation pit support. Furthermore, two guide wheels 42 are provided, and are arranged along the length direction of the rod body 41.

[0040] In some embodiments, see Appendix Figure 5 As shown, the guide channel is provided with a limiting guide groove 22 along its length direction for the guide wheel portion 422 to abut against. Since the inclinometer rod 4 is in a free-falling state when the cable portion is unwinding, the limiting guide groove 22 can limit the moving direction of the guide wheel portion 42, thereby preventing the inclinometer rod 4 from twisting in the guide channel.

[0041] Furthermore, a trumpet-shaped opening 23 is formed at one end of the guide passage away from the fixed housing 1 .

[0042] During the design, in order to ensure that the guide wheel part 42 always abuts against the foundation pit support, the length of the rotating shaft 421 of the guide wheel part 42 is greater than the inner diameter of the foundation pit support, so that the guide wheel part 42 is in an inclined state when in the foundation pit support (the rotating shaft 421 is inclined, one guide wheel 422 is at a higher position, and the other guide wheel 422 is at a lower position). In this case, the guide wheel part 42 always has a tendency to rotate. Since the radial dimension of the guide channel is smaller than the inner diameter of the foundation pit support, when the guide wheel part 42 enters the foundation pit support from the guide channel, the guide wheel part 42 will have a certain rotation amplitude. At this time, the setting of the trumpet-shaped opening 23 can slow down the rotation amplitude of the guide wheel part 42, so that the guide wheel part 42 can enter the foundation pit support more smoothly. And when the inclinometer rod 4 is retracted, the setting of the trumpet-shaped opening 23 can also guide the guide wheel part 42 back into the guide channel.

[0043] In some embodiments, see Appendix Figure 4 As shown, the locking portion 3 includes a locking cover 31 that can be sleeved on the guide tube 2 , and a locking slot 32 that can be snapped onto the guide tube 2 is provided on the locking cover 31 .

[0044] Specifically, a clamping column 24 is provided on the side wall of the guide tube 2, and the locking groove 32 includes a first groove 321 and a second groove 322 which are arranged vertically and interconnected; the first groove 321 is arranged along the length direction of the guide tube 2; when the locking cover 31 is put on the guide tube 2, the clamping column 24 can enter the first groove 321; when the clamping column 24 enters the junction of the first groove 321 and the second groove 322, the guide tube 2 or the locking cover 31 is rotated to make the clamping column 24 enter the second groove 322, thereby realizing the clamping fixation of the locking cover 31 and the guide tube 2.

[0045] Furthermore, a recess 311 recessed in the direction of the guide channel is provided in the middle of the locking cover 31. When the locking slot 32 is clamped onto the guide tube 2, the recess 311 can abut against the inclinometer rod 4. The inclinometer rod 4 is stopped by the recess 311 to prevent the inclinometer rod 4 from slipping in the guide channel in the locked state.

[0046] In order to reduce the overall weight of the inclinometer, in some embodiments, see the attached Figure 5 As shown, at least one weight-reducing hole 25 communicating with the guide channel is arranged on the side wall of the guide tube 2. Furthermore, a handle 26 is arranged on the outer wall of the guide tube 2 to facilitate lifting the inclinometer.

[0047] The above implementation modes are only for illustrating the technical concept and features of the utility model, and their purpose is to allow people familiar with this technology to understand the content of the utility model and implement it. It cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
