For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0033] according to Figure 1 As shown, the verticality detection device for foundation pit excavation provided by the present invention includes a base 10, an adjustment component, and a detection component 30.

[0034] The adjustment assembly is installed on the base 10. The adjustment assembly includes a fixing member 21, an adjusting member 22, a movable member 23, and a guide member 24. The fixing member 21 is provided with a receiving part 211. The movable member 23 and the guide member 24 are both located in the receiving part 211. The adjusting member 22 is movably disposed in the receiving part 211. The movable member 23 is connected to the adjusting member 22 and the guide member 24 respectively. The movable member 23 can move along the length direction of the guide member 24 under the drive of the adjusting member 22.

[0035] The detection component 30 is mounted on the movable part 23. The detection component 30 is a functional component used to detect perpendicularity and is connected to the movable part 23. It can move with the movable part 23. For example... Figure 1 As shown, the detection component 30 is a laser detector, and the detection component 30 also includes a laser head 31, which can change its position as the movable part 23 moves.

[0036] Specifically, the fixing member 21 is block-shaped or plate-shaped, and a portion of the fixing member 21 is hollow to form a receiving part 211. The adjusting member 22 can drive the movable member 23 to move along the length direction of the adjusting member 22. For example, the adjusting member 22 is a pull rod, and the movable member 23 is fixedly connected to the adjusting member 22. Pulling the adjusting member 22 drives the movable member 23 to move.

[0037] The guide member 24 is used to guide and limit the linear movement of the movable member 23, preventing the detection component 30 mounted on the movable member 23 from shaking during movement. The length direction of the guide member 24 is parallel to the length direction of the adjusting member 22. The guide member 24 can be in the form of a guide rail, guide groove, guide rod, etc., as long as it can guide and limit the linear movement of the movable member 23 along the length direction of the adjusting member 22. For example, the guide member is in the shape of a straight rod, and the guide member is movably inserted into the movable member 23, and the movable member 23 moves along the length direction of the guide member 24.

[0038] The verticality detection device for foundation pit excavation provided by the present invention, by installing the detection component 30 on the movable part 23 and movably setting the adjusting part 22 in the receiving part 211, and connecting the movable part 23 to the adjusting part 22 and the guide part 24 respectively, allows the detection component 30 and the movable part 23 to move along the length direction of the guide part 24 under the drive of the adjusting part 22; under the guidance of the guide part 24, the detection component 30 can move linearly with the movable part 23, reducing the shaking of the detection component 30 during the movement, improving the movement stability of the detection component 30 during the adjustment process, which is beneficial to enhancing the reliability of the verticality detection device and improving the accuracy of verticality detection.

[0039] Furthermore, the adjusting member 22 is a screw, and the movable member 23 is provided with a connecting hole. The connecting hole is provided with an internal thread, which is adapted to the external thread of the adjusting member 22. The adjusting member 22 passes through the connecting hole and is rotatably disposed in the receiving part 211.

[0040] The connecting hole is a through hole that passes through the movable part 23. The outer periphery of the adjusting part 22 is provided with an external thread, and the inner wall of the connecting hole is provided with an internal thread that matches the external thread. The adjusting part 22 is threadedly connected to the movable part 23. By rotating the adjusting part 22 along its own axis, the movable part 23 can be driven to move linearly along the length direction of the adjusting part 22.

[0041] One end of the adjusting member 22 protrudes outward relative to the fixing member 21, facilitating rotation of the adjusting member 22. Preferably, a knob 221 is provided on the protruding end of the adjusting member 22 relative to the fixing member 21. The knob 221 is perpendicular to the length direction of the adjusting member 22, making it easy for a person to hold. By rotating the knob 221, the adjusting member 22 can be rotated along its own axis.

[0042] Furthermore, the adjustment assembly also includes a connector 25, which is connected to the movable member 23. The guide member 24 has a guide groove 241, and the connector 25 is provided with a pulley 251, which is housed in the guide groove 241 and can move along the guide groove 241.

[0043] like Figure 1 As shown, the guide member 24 is block-shaped and has a guide groove 241 extending along its length, with the opening of the guide groove 241 facing the bottom surface of the connector 25. The connector 25 is cuboid in shape and is mounted on the top of the movable member 23, moving synchronously with the movable member 23. A pulley 251 is provided on the bottom surface of the connector 25, which can be accommodated in the guide groove 241 and can move along the extending direction of the guide groove 241.

[0044] The working principle of adjusting the position of the detection component 30 using the verticality detection device for foundation pit excavation provided by the present invention is as follows: rotating the knob 221 drives the adjusting component 22 to rotate along its own axis. The movable component 23 moves linearly along the length direction of the adjusting component 22 under the cooperation of the internal and external threads. At the same time, the connecting component 25 moves synchronously with the movable component 23. The pulley 251 moves in the guide groove 241 along the extension direction of the guide groove 241 to guide and limit the movable component 23, thereby improving the stability of the detection component 30 during the movement, avoiding vibration or shaking of the detection component 30, and also preventing a decrease in the measurement accuracy of the detection component 30.

[0045] Preferably, there are multiple pulleys 251, and all of the multiple pulleys 251 are accommodated in the guide groove 241. The multiple pulleys 251 are spaced apart along the width direction of the connector 25, so that the multiple pulleys 251 are distributed in the guide groove 241 along the extension direction of the guide groove 241.

[0046] In an optional embodiment, the pulley 251 is perpendicular to the bottom surface of the connector 25, the outer peripheral surface of the pulley 251 contacts the bottom of the guide groove 241 and slides along the bottom of the groove, and the thickness of the pulley 251 is adapted to the width of the guide groove 241.

[0047] In another optional embodiment, pulley 251 is parallel to the bottom surface of connector 25, and the outer diameter of pulley 251 is adapted to the width of guide groove 241. In this embodiment, pulley 251 is parallel to the horizontal plane, the rotation axis of pulley 251 is perpendicular to the bottom surface of connector 25, the outer peripheral surface of pulley 251 contacts the side wall of guide groove 241, and pulley 251 slides along the side wall of guide groove 241. By setting pulley 251 to be parallel to the bottom surface of connector 25, and the outer diameter of pulley 251 to be adapted to the width of guide groove 241, during the movement of movable component 23, it can be ensured that pulley 251 is always in contact with the side wall of guide groove 241, avoiding horizontal shaking of movable component 23 and preventing the stability of detection component 30 from being affected.

[0048] Furthermore, there are two guide members 24, which are distributed at intervals on both sides of the adjusting member 22, and pulleys 251 are provided on both sides of the connecting member 25 along its length.

[0049] In this embodiment, two guide members 24 are spaced parallel to each other along a direction perpendicular to the length direction of the adjusting member 22. The bottom surfaces of both sides of the connecting member 25 along its length are respectively provided with pulleys 251, one pulley 251 being housed in the guide groove 241 of the first guide member 24, and the other pulley being housed in the guide groove 241 of the second guide member 24. Multiple pulleys 251 can be provided on each side, for example... Figure 2 As shown, three pulleys 251 are provided on each side of the connector 25 along its length.

[0050] By setting two guide members 24, it is beneficial to guide and limit the two sides of the moving part 23, thereby enhancing the stability and balance of the detection component 30 during movement.

[0051] In one embodiment, the connector 25 is further provided with a mounting frame 252, which is mounted on the bottom surface of the connector 25.

[0052] The mounting frame 252 includes a top plate 252a, a bottom plate 252b, and two side plates 252c disposed between the top plate 252a and the bottom plate 252b. A pulley 251 is installed inside the mounting frame 252. The bottom plate 252b is in movable contact with the bottom of the guide groove 241. The length direction of the bottom plate 252b is parallel to the length direction of the guide member 24. The two side plates 252c are located at both ends of the length direction of the bottom plate 252b.

[0053] like Figure 2 As shown, the mounting frame 252 is rectangular. The top plate 252a of the mounting frame 252 is detachably or fixedly mounted to the bottom surface of the connector 25 via the connecting strip 252d. The rotation axis of the pulley 251 is vertically mounted between the top plate 252a and the bottom plate 252b. The bottom plate 252b contacts the bottom of the guide groove 241 and can move along the bottom of the guide groove 241. The mounting frame 252 provides mounting space for the pulley 251 and also facilitates linear guidance of the moving part 23 and the detection assembly 30.

[0054] It is understandable that the width of the base plate 252b and the side plate 252c is smaller than the outer diameter of the pulley 251, so as to avoid increasing the motion resistance between the pulley 251 and the guide groove 241.

[0055] There can be two mounting boxes 252, for example Figure 2As shown, two mounting frames 252 are distributed parallel to each other on both sides of the length direction of the connector 25, and each mounting frame 252 is equipped with three pulleys 251.

[0056] like Figure 3 As shown, the verticality detection device for the support frame used for foundation pit excavation also includes a height adjustment component 40. The height adjustment component 40 includes a support member 41 and a height adjustment component 42. The support member 41 is fixed to the base 10, and one end of the height adjustment component 42 is connected to the support member 41, while the other end is connected to the adjustment component.

[0057] The connection position between the height adjustment component 42 and the support component 41 can be adjusted along the length of the support component 41 so that the distance between the adjustment component and the base 10 can be adjusted.

[0058] Specifically, the support member 41 is vertically mounted on the base 10 in the shape of a rod. A connecting ring 411 is also provided at the bottom of the support member 41. The connecting ring 411 is sleeved on the outer periphery of the support member 41 to enhance the connection stability between the support member 41 and the base 10. The height adjustment member 42 is rod-shaped and one end is movably connected to the support member 41, while the other end is connected to the fixing member 21.

[0059] The height adjustment component 42 and the support component 41 can be connected and adjusted through structures such as guide rails, slides, through holes, and locking components. For example, both the height adjustment component 42 and the support component 41 are hollow rods, and each has two through holes. By aligning the through holes of the height adjustment component 42 and the support component 41 to form a channel, and inserting the locking component into the channel, the height adjustment component 42 and the support component 41 are connected. The height adjustment component 42 or the support component 41 has multiple through holes spaced apart along its own length. By aligning the through holes of different heights, channels of different heights can be formed, thereby adjusting the distance between the adjustment component and the base 10.

[0060] In one specific embodiment, a protrusion 421 is provided on the outer wall of one end of the height adjusting member 42. The protrusion 421 is elastic and can extend or retract relative to the outer peripheral surface of the height adjusting member 42. The support member 41 is hollow inside, and the outer wall of the support member 41 is provided with a plurality of mounting holes 412. The plurality of mounting holes 412 are spaced apart along the length direction of the support member 41. The height adjusting member 42 is inserted into the interior of the support member 41, and the protrusion 421 is inserted into the mounting holes 412.

[0061] In this embodiment, the protrusion 421 is elastically disposed on the outer wall of the height adjusting member 42, and the protrusion 421 is capable of radial extension and retraction along the height adjusting member 42. The height adjusting member 42 is inserted into the interior of the support member 41, and the protrusion 421 can be inserted into mounting holes 412 at different heights. Exemplarily, the protrusion 421 is hemispherical.

[0062] The working principle of adjusting the distance between the adjustment component and the base 10 by using the protrusion 421 is as follows: applying force to the protrusion 421 causes the protrusion 421 to retract inward relative to the outer peripheral surface of the height adjustment component 42; moving the height adjustment component 42 to an appropriate position in the vertical direction causes the protrusion 421 to move to the corresponding mounting hole 412 at that position. Under the action of elasticity, the protrusion 421 extends out relative to the outer peripheral surface of the height adjustment component 42 and is inserted into the mounting hole 412, thus completing the height adjustment of the adjustment component.

[0063] In this embodiment, by providing the protrusion 421 and the mounting hole 412, the labor intensity of the operator when adjusting the height of the adjustment component is reduced, the adjustment method is simple, and it helps to improve the operator's work efficiency.

[0064] Optionally, a protrusion 421 may be provided on the outer wall of one end of the support member 41. The protrusion 421 is elastic and can extend or retract relative to the outer peripheral surface of the support member 41. The height adjustment member 42 is hollow inside, and the outer wall of the height adjustment member 42 is provided with a plurality of mounting holes 412. The plurality of mounting holes 412 are spaced apart along the length direction of the height adjustment member 42. The support member 41 is inserted into the interior of the height adjustment member 42, and the protrusion 421 is inserted into the mounting holes 412.

[0065] Furthermore, there are two height adjustment components 40, which are distributed at intervals along a direction perpendicular to the length of the adjustment member 22 to enhance the support stability of the adjustment components.

[0066] The bottom surface of the base 10 is provided with an anti-slip element 11. The anti-slip element 11 has a rough surface. The size and shape of the anti-slip element 11 are adapted to the size and orientation of the bottom surface of the base 10. The anti-slip element 11 is used to enhance the friction between the base 10 and the contact surface and improve the stability of the base 10 on the contact surface.

[0067] In one specific embodiment, the method of using the support verticality detection device for foundation pit excavation provided by the present invention is as follows:

[0068] The device is placed on a flat surface. The anti-slip part 11 of the base 10 enhances the friction between the base 10 and the flat surface. The height of the adjusting component is adjusted according to actual needs. Force is applied to the protrusion 421, causing it to retract relative to the outer circumferential surface of the height adjusting component 42. The height adjusting component 42 is moved vertically to an appropriate position, and the protrusion 421 moves to the corresponding mounting hole 412. Under the action of elasticity, the protrusion 421 extends relative to the outer circumferential surface of the height adjusting component 42 and inserts into the mounting hole 412, completing the height adjustment of the adjusting component. According to actual needs, the horizontal position of the detection component 30 is adjusted. Rotating the knob 221 causes the adjusting component 22 to rotate along its own axis. The movable component 23 moves linearly along the length of the adjusting component 22 under the cooperation of the internal and external threads. At the same time, the connecting component 25 moves synchronously with the movable component 23. The pulley 251 moves in the guide groove 241 along the extension direction of the guide groove 241 to guide and limit the movable component 23, which improves the stability of the detection component 30 during the movement, avoids the detection component 30 from shaking or wobbling, and also prevents the measurement accuracy of the detection component 30 from decreasing.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
