Description

Technical Field

[0001] This invention relates to the field of building construction surveying technology, specifically a surveying device for wall and column construction. Background Technology

[0002] In building construction, the accurate measurement of the verticality, flatness, and geometric dimensions of vertical components such as walls and columns is crucial for ensuring structural safety, spatial regularity, and the quality of subsequent decoration work. Traditional measurement methods rely heavily on manual operation, resulting in low efficiency and large fluctuations in accuracy, making it difficult to meet the high precision and efficiency requirements of modern industrialized construction.

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0025] It should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0026] Example 1, please refer to Figures 1-4A measuring device for wall and column construction includes an arc-shaped base plate 1. Several legs 2 are fixedly connected to the bottom of the arc-shaped base plate 1. Two symmetrically arranged clamping and connecting mechanisms 3 are fixedly connected to the inner side of the arc-shaped base plate 1. A support displacement groove 4 is provided on the side of the arc-shaped base plate 1. An installation displacement groove 5 is provided on the arc-shaped base plate 1. A support displacement mechanism 6 is provided on the support displacement groove 4. A lifting support wheel mechanism 7 is provided at the bottom of the support displacement mechanism 6. A rotation displacement mechanism 8 is provided on the installation displacement groove 5. A lifting adjustment mechanism 9 is provided on the rotation displacement mechanism 8. Several lifting arc plate mechanisms 10 are provided on the lifting adjustment mechanism 9. Several laser detection mechanisms 11 are provided on the lifting arc plate mechanism 10. The clamping and connecting mechanisms 3 are used to connect the wall and column. The support displacement mechanism 6 is used to drive the lifting support wheel mechanism 7 to move and shift. The lifting support wheel mechanism 7 is used to adjust the horizontal state of the arc-shaped base plate 1. The rotation displacement mechanism 8 is used to drive the lifting adjustment mechanism 9 to rotate and shift. The lifting adjustment mechanism 9 is used to drive the lifting arc plate mechanism 10 to rise and fall.

[0027] The support displacement mechanism 6 includes a displacement arc plate 601 disposed within the support displacement groove 4. The displacement arc plate 601 and the arc-shaped base plate 1 are slidably connected. The displacement arc plate 601 is fixedly connected to a first motor base 602 and a second motor base 605. The first motor base 602 is fixedly connected to a first motor 603. The output shaft of the first motor 603 is fixedly connected to a first gear 604. The second motor base 605 is fixedly connected to a second motor 606. The output shaft of the second motor 606 is fixedly connected to a second gear 607. A first arc-shaped rack 608 is fixedly connected to the side of the arc-shaped base plate 1. The first arc-shaped rack 608 meshes with the first gear 604 and the second gear 607. The lifting support wheel mechanism 7 includes a second linear motor 701 fixed to the bottom of the displacement arc plate 601. The bottom of the second linear motor 701 is rotatably connected to a support wheel frame 702. The support wheel frame 702 is rotatably connected to a support wheel 703.

[0028] Specifically, when the arc-shaped base plate 1 is not horizontal, the first motor 603 and the second motor 606 are activated, thereby driving the first gear 604 and the second gear 607 to mesh. Since there is a notch on the arc-shaped base plate 1 and there are two gears, the first gear 604 and the second gear 607, it can be ensured that there is always a gear meshing with the first arc-shaped rack 608, so that the displacement arc plate 601 can move along the support displacement groove 4 on the arc-shaped base plate 1. The length of the displacement arc plate 601 is greater than the length of the arc-shaped base plate 1, so the displacement arc plate 601 can drive the support wheel 703 to move to the position where the lowest angle adjustment is required. At this time, the second linear motor 701 is activated, which can push the support wheel frame 702 and the support wheel 703, thereby adjusting the arc-shaped base plate 1 to a horizontal state.

[0029] The rotary displacement mechanism 8 includes a rotary arc plate 801 mounted on the displacement groove 5. A second arc-shaped rack 802 is fixedly connected to the outer side of the rotary arc plate 801. A third motor 803 and a fourth motor 805 are fixedly connected to the arc-shaped base plate 1. A third gear 804 is fixedly connected to the output shaft of the third motor 803. A fourth gear 806 is fixedly connected to the output shaft of the fourth motor 805. The second arc-shaped rack 802 meshes with the third gear 804 and the fourth gear 806.

[0030] Specifically, the length of the rotating arc plate 801 is greater than the length of the notch in the arc-shaped base plate 1, which also ensures that there is always a gear in the third gear 804 and the fourth gear 806 meshing with the second arc-shaped rack 802. At this time, the third motor 803 and the fourth motor 805 can drive the third gear 804 and the fourth gear 806 to rotate, thereby driving the rotating arc plate 801 to move along the mounting displacement groove 5.

[0031] The lifting and adjusting mechanism 9 includes a first sliding shaft 901 and a second sliding shaft 902 fixed on the rotating arc plate 801. The ends of the first sliding shaft 901 and the second sliding shaft 902 away from the rotating arc plate 801 are fixedly connected to a top arc plate 903. A fifth motor 904 is provided on the top arc plate 903. The output shaft of the fifth motor 904 is fixedly connected to a lifting rod 905. The lifting rod 905 is provided with a threaded groove. The lifting rod 905 is rotatably connected to the top arc plate 903 and the arc-shaped base plate 1. The lifting arc plate mechanism 10 includes an arc-shaped housing 1001, a first sliding shaft 901 and a second sliding shaft 902 passing through the arc-shaped housing 1001, and the first sliding shaft 901 and the second sliding shaft 902 are slidably connected to the arc-shaped housing 1001. An arc-shaped groove is provided inside the arc-shaped housing 1001, and a movable arc plate 1002 is provided on the arc-shaped groove. The movable arc plate 1002 is slidably connected to the arc-shaped housing 1001. A first displacement groove 1003 is provided on the movable arc plate 1002, and a lifting threaded groove 1004 is provided on one side of the first displacement groove 1003. A second displacement groove 1004 is also provided on the movable arc plate 1002. 5. A first friction plate 1006 is provided on the movable arc plate 1002 at the position of the second displacement groove 1005, and a second friction plate 1008 is provided on the movable arc plate 1002 at the position of the third displacement groove 1007. An arc-shaped housing 1001 is rotatably connected to a first rotating shaft 1009, which is rotatably connected to a third linear motor 1010. The end of the third linear motor 1010 away from the first rotating shaft 1009 is rotatably connected to a second rotating shaft 1011. The second rotating shaft 1011 and the movable arc plate 1002 are rotatably connected. The arc-shaped housing 1001 is provided with several magnetic insertion holes. The laser detection mechanism 11 includes a magnetic insertion rod 1101, which is fixedly connected to a laser measuring device 1102.

[0032] Specifically, turning on the third linear motor 1010 will drive the movable arc plate 1002 to move along the arc groove. When the arc shell 1001 needs to be raised or lowered, the lifting threaded groove 1004 will contact the lifting rod 905. At this time, the first friction plate 1006 will not contact the first sliding shaft 901, and the second friction plate 1008 will not contact the second sliding shaft 902. At this time, turning on the fifth motor 904 will cause the output shaft of the fifth motor 904 to rotate, which will drive the lifting rod 905 to rotate, thereby driving the threaded groove to rotate, and then driving the movable arc plate 1002 to rise or fall. At this time, turning on the laser measuring device 1102 will be able to measure the dimensions of the wall column at a specified height.

[0033] Additionally, when the arc-shaped housing 1001 needs to be fixed at a specified height, the third linear motor 1010 is activated, causing the moving arc plate 1002 to move along the arc groove, so that the first friction plate 1006 contacts the first sliding shaft 901, and at the same time the second friction plate 1008 contacts the second sliding shaft 902. At this time, the lifting threaded groove 1004 no longer contacts the lifting rod 905, and the rotation of the lifting rod 905 will not drive the moving arc plate 1002 to rise or fall.

[0034] A horizontal sensor is provided on the arc-shaped base plate 1.

[0035] Example 2, see below. Figures 1-3 In this embodiment of the invention, the clamping and connecting mechanism 3 includes a first linear motor 301 fixed to the inner side of the arc-shaped base plate 1, and the end of the first linear motor 301 is fixedly connected to the clamping plate 302.

[0036] Specifically, activating the first linear motor 301 can drive the clamping plate 302 to feed, thereby causing the clamping plate 302 to abut against the central reference body, so as to connect the equipment to it and ensure the stability of the equipment.

[0037] In the implementation of this invention, the device is first placed in a designated position. If a wall column is needed as a reference surface, the clamping connection mechanism 3 is activated to clamp the device onto the object in the middle. If the device needs to be adjusted to a horizontal state, the clamping connection mechanism 3 is not activated; instead, the lifting support wheel mechanism 7 is activated, along with the support displacement mechanism 6. This causes the lifting support wheel mechanism 7 to rotate and shift, quickly adjusting the arc-shaped base plate 1 to a horizontal state. Then, a specified number of laser detection mechanisms 11 are installed on the lifting arc plate mechanism 10. By activating the lifting adjustment mechanism 9, the laser detection mechanisms 11 can be raised and lowered to measure the height of the wall column. The device can also measure different height positions of the wall column. Activating the rotation displacement mechanism 8 causes the lifting adjustment mechanism 9 to rotate, which in turn causes the lifting arc plate mechanism 10 and the laser detection mechanisms 11 to rotate around the wall column to achieve coverage measurement.

[0038] This invention enables connection with the wall column through the clamping and connecting mechanism 3, thereby locating the reference surface and ensuring the stability of the arc-shaped base plate. The position of the lifting support wheel mechanism 7 can be adjusted through the support displacement mechanism 6, which, together with the lifting support wheel mechanism 7, can quickly adjust the arc-shaped base plate 1 to a horizontal state while ensuring its stability. The circumferential position of the laser detection mechanism 11 can be quickly adjusted through the rotation displacement mechanism 8, thereby performing circumferential measurement of the wall column. The lifting adjustment mechanism 9 can drive the lifting arc plate mechanism 10 to rise and fall, thereby driving the laser detection mechanism 11 to rise and fall, so as to achieve fixed-point measurement of the wall column and improve the efficiency of wall column construction measurement.

[0039] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention.
