Description

Technical Field

[0001] This invention relates to the field of positioning equipment technology, and more specifically, to an auxiliary positioning device for measuring building tilt and settlement. Background Technology

[0002] The main methods for measuring building tilt include: point projection method, horizontal angle measurement method, forward intersection method, laser plumb line method, hanging method, inclinometer method, and differential settlement method. When using settlement measurement, a measuring instrument can be employed to perform the measurement.

[0003] Existing measuring instruments are generally fixed with a fixed support frame. Although the support frame can be adjusted along the height, the position of its contact point with the ground cannot be adjusted. This causes the support frame to easily tip over when it is too high, resulting in damage to the measuring instrument. Summary of the Invention

[0004] The problem this invention addresses is how to improve the stability of the measuring instrument.

[0005] To address the aforementioned problems, this invention provides an auxiliary locator for measuring building tilt and settlement, comprising a lifting drive assembly and a support adjustment assembly. The lifting drive assembly is used to adjust the height of the measuring device. The support adjustment assembly is located below the lifting drive assembly and includes multiple sets of support structures. The multiple sets of support structures are evenly distributed at the lower end of the lifting drive assembly and are all slidably connected to the lifting drive assembly. The lifting drive assembly is drive-connected to the support adjustment assembly. When the lifting drive assembly adjusts the measuring device to a higher position, it causes the multiple sets of support structures to slide out from the lower end of the lifting drive assembly.

[0006] Optionally, the lifting drive assembly includes a base plate, the support structure includes a support block and a first connecting rod, the support block is located below the base plate, and a guide cylinder corresponding to the support structure is installed at the upper end of the base plate, the axial direction of the guide cylinder is consistent with the sliding direction of the corresponding support block;

[0007] In each of the support structures, one end of the first connecting rod is connected to the support block, and the other end passes through the corresponding guide cylinder and is slidably connected to the guide cylinder.

[0008] Optionally, the lifting drive assembly further includes a drive structure mounted on the base plate, the drive structure being used to adjust the height of the measuring instrument;

[0009] The support adjustment assembly also includes a turntable, and the support structure also includes a second connecting rod. Multiple support blocks of the support structure are evenly slidably connected to the lower end of the turntable, and the turntable is rotatably connected to the lower end of the base plate.

[0010] In each of the support structures, one end of the second link is hinged to the edge of the turntable, and the other end is hinged to the first link; the drive structure is driven to one of the first links of the plurality of support structures. When the drive structure adjusts the height of the measuring device, the first link connected to the drive structure drives the turntable to rotate through the corresponding second link, so as to realize that the plurality of support blocks slide out from the lower end of the lifting drive assembly.

[0011] Optionally, the support structure further includes a support column, which is installed at the lower center of the turntable, and a plurality of support blocks are evenly arranged around the support column and in contact with the support column, and the plurality of support blocks are used to slide in a direction away from the support column.

[0012] Optionally, the lifting drive assembly further includes a limiting post, one end of which is connected to the upper end of the base plate, and the other end extends above the first connecting rod and is connected to the drive structure.

[0013] Optionally, the drive structure includes a column, a fixed base, and a fixed sleeve. The fixed base is mounted on the base plate and located above the first connecting rod. One end of the fixed sleeve is fixed to the fixed base. One end of the column is slidably connected to the fixed sleeve, and the other end extends out of the fixed sleeve and is used to connect to the measuring instrument.

[0014] Optionally, the driving structure further includes a driving link and a slider. The fixed base is provided with a sliding groove, the slider is slidably connected to the sliding groove, the slider is driven to the column through the driving link, and the bottom end of the slider is driven to the first link through a connector.

[0015] Optionally, the drive structure further includes a lead screw, a nut, and a transmission link. The lead screw is parallel to the column and located at the end of the slider away from the column, and is rotatably connected to the fixed seat. The nut is threadedly connected to the lead screw, and the transmission link is hinged between the slider and the nut.

[0016] Optionally, the drive structure further includes an adjustment seat, which is rotatably connected to the end of the column away from the fixed seat and is used for rotatably connecting with the measuring instrument.

[0017] Optionally, the drive structure further includes a locking element adapted to restrict relative rotation between the adjusting seat and the column.

[0018] Compared with the prior art, the building tilt and settlement measurement auxiliary locator of the present invention has a support adjustment component located below the lifting drive component used to adjust the height of the measuring device, and includes multiple sets of support structures. These multiple sets of support structures are evenly distributed at the lower end of the lifting drive component, so that the lifting drive component can be supported by multiple sets of support structures. The multiple sets of support structures are slidably connected to the lifting drive component, and the lifting drive component is drively connected to the support adjustment component. When the lifting drive component is used to adjust the height of the measuring device, the multiple sets of support structures slide out from the lower end of the lifting drive component and are fixed to the ground. The sliding out of the lower end of the lifting drive component increases the support area or support range of the multiple sets of support structures. In this way, when the height of the measuring device increases, the contact area between the multiple sets of support structures and the ground is expanded, and the support for the lifting drive component is more stable, thereby improving the stability of the measuring device.

[0029] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in sequences other than those illustrated or described herein.

[0030] Referring to Figure 1, the present invention provides an auxiliary locator for measuring building tilt and settlement, including a lifting drive assembly and a support adjustment assembly 200. The lifting drive assembly is used to adjust the height of the measuring device 10. The support adjustment assembly 200 is located below the lifting drive assembly and includes multiple sets of support structures 210. The multiple sets of support structures 210 are evenly distributed at the lower end of the lifting drive assembly and are all slidably connected to the lifting drive assembly. The lifting drive assembly and the support adjustment assembly 200 are connected by transmission. When the lifting drive assembly is used to adjust the height of the measuring device 10, the multiple sets of support structures 210 slide out from the lower end of the lifting drive assembly and are fixed to the ground.

[0031] Specifically, the height direction of the measuring device 10 is aligned with the Z-axis, and the ground is the XY plane. The lifting drive assembly adjusts the position of the measuring device 10 along the Z-axis. The support adjustment assembly 200 is located below the lifting drive assembly and includes multiple sets of support structures 210. These multiple sets of support structures 210 are evenly distributed at the lower end of the lifting drive assembly and are in sliding contact with it. When the lifting drive assembly is used to adjust the measuring device 10 to rise, the multiple sets of support structures 210 slide out from the lower end of the lifting drive assembly and are fixed to the ground. When the lifting drive assembly is used to adjust the measuring device 10 to fall, the multiple sets of support structures 210 slide into the lower end of the lifting drive assembly and are fixed to the ground. "The support structure 210 slides out from the lower end of the lifting drive assembly" means that the support structure 210 moves from being below the lifting drive assembly to extending below it; therefore, the support structure 210 slides along the horizontal plane.

[0032] Therefore, in this embodiment, the support adjustment component 200 is located below the lifting drive component used to adjust the height of the measuring device 10, and includes multiple sets of support structures 210. The multiple sets of support structures 210 are evenly distributed at the lower end of the lifting drive component, so that the lifting drive component can be supported by the multiple sets of support structures 210. The multiple sets of support structures 210 are slidably connected to the lifting drive component, and the lifting drive component is drively connected to the support adjustment component 200. When the lifting drive component is used to adjust the height of the measuring device 10, the multiple sets of support structures 210 slide out from the lower end of the lifting drive component and are fixed to the ground. The sliding out of the multiple sets of support structures 210 from the lower end of the lifting drive component increases the support area or support range of the multiple sets of support structures 210. In this way, when the height of the measuring device 10 is increased, the contact range between the multiple sets of support structures 210 and the ground is expanded, and the support for the lifting drive component is more stable, thereby improving the stability of the measuring device 10.

[0033] Optionally, combined Figure 2 As shown, the lifting drive assembly includes a base plate 110, and a support structure 210 includes a support block 211 and a first connecting rod 212. The support block 211 is located below the base plate 110, and a guide cylinder 111 corresponding to each support structure 210 is installed on the upper end of the base plate 110. The axial direction of the guide cylinder 111 is consistent with the sliding direction of the corresponding support block 211. In each support structure 210, one end of the first connecting rod 212 is connected to the support block 211, and the other end passes through the corresponding guide cylinder 111 and is slidably connected to the guide cylinder 111.

[0034] Specifically, the first connecting rod 212 has an L-shaped rod structure, but it can also be other shapes. The support block 211 slides in contact with the lower end of the base plate 110, and a guide cylinder 111 is installed on the upper end of the base plate 110. The axial direction of the guide cylinder 111 is consistent with the sliding direction of the corresponding support block 211. In each support structure 210, one side of the first connecting rod 212 is welded to the support block 211, and the other side passes through the corresponding guide cylinder 111 and is slidably connected to the guide cylinder 111.

[0035] Thus, guide cylinders 111, corresponding one-to-one with support structures 210, are installed on the upper end of the base plate 110. The axial direction of the guide cylinders 111 is consistent with the sliding direction of the corresponding support blocks 211, so that the support blocks 211 correspond to the guide cylinders 111. In each support structure 210, one end of the first connecting rod 212 is connected to the support block 211, and the other end passes through the corresponding guide cylinder 111 and is slidably connected to the guide cylinder 111. The sliding of the support block 211 relative to the base plate 110 can be guided by the sliding connection between the first connecting rod 212 and the guide cylinder 111, so as to ensure that the moving direction of the support block 211 will not deviate, thereby ensuring that each support structure 210 slides along its own sliding direction, avoiding mutual interference between multiple support blocks 211, and improving the sliding efficiency of multiple support blocks 211.

[0036] Optionally, combined Figure 1 and Figure 2 As shown, the lifting drive assembly also includes a drive structure 120, which is mounted on the base plate 110 and is used to adjust the height of the measuring device 10. The support adjustment assembly 200 also includes a turntable 213, and the support structure 210 also includes a second connecting rod 214. The support blocks 211 of the multiple support structures 210 are evenly slidably connected to the lower end of the turntable 213, and the turntable 213 is rotatably connected to the lower end of the base plate 110. In each support structure 210, one end of the second connecting rod 214 is hinged to the edge of the turntable 213, and the other end is hinged to the first connecting rod 212. The drive structure 120 is driven by one of the first connecting rods 212 of the multiple support structures 210. When the drive structure 120 adjusts the measuring device 10 to rise, the first connecting rod 212 connected to the drive structure 120 drives the turntable 213 to rotate through the corresponding second connecting rod 214, so that the multiple support blocks 211 slide out from the lower end of the lifting drive assembly.

[0037] Specifically, the drive structure 120 is mounted on the base plate 110, and the lifting drive assembly is used to adjust the height of the measuring device through the drive structure 120. Taking the base plate 110 as a circular plate as an example, the turntable 213 is coaxial with the base plate 110 and is rotatably connected to the lower end of the base plate 110 through a rotating shaft. Multiple support blocks 211 are in sliding contact with the lower end of the turntable 213. The support blocks 211, the first connecting rod 212, and the second connecting rod 214 correspond one-to-one. The diameter of the turntable 213 is larger than the diameter of the base plate 110, and a hinge shaft is provided at the edge of the turntable 213. This hinge shaft is connected to one end of the second connecting rod 214, and the other end of the second connecting rod 214 is hinged to the first connecting rod 212. The drive structure 120 is driven by one of the multiple first connecting rods 212. When the drive structure 120 is used to adjust the height of the measuring device, the first connecting rod 212 connected to the drive structure 120 performs two functions through the drive structure 120: First, the... The first link 212 pushes the support block 211 connected to it to slide out from under the turntable 213. Alternatively, the movement of the first link 212 applies a force to the corresponding second link 214, increasing the angle between the second link 214 and the first link 212. The second link 214 then applies a circumferential force to the turntable 213 via a hinge axis, causing the turntable 213 to rotate. As the turntable 213 rotates, the angles between the remaining second links 214 and their respective corresponding first links 212 increase, causing the first links 212 corresponding to the remaining second links 214 to simultaneously slide their corresponding support blocks 211 out from under the turntable 213. Both of these actions occur simultaneously. When the drive structure 120 is used to adjust the height of the measuring device, the first connecting rod 212 connected to the drive structure 120 drives the turntable 213 to rotate via the corresponding second connecting rod 214, so that multiple support blocks 211 slide out from the lower end of the lifting drive assembly and are fixed to the ground. In this way, the adjustment of the height of the measuring device 10 and the sliding of the multiple support blocks 211 are synchronized, thereby improving the efficiency of the building tilt and settlement measurement auxiliary locator and thus improving the measurement efficiency.

[0038] Optionally, combined Figure 3 As shown, the support structure 210 also includes a support column 215, which is installed at the lower center of the turntable 213. Multiple support blocks 211 are evenly arranged around the support column 215 and in contact with the support column 215. The multiple support blocks 211 are used to slide in a direction away from the support column 215.

[0039] Specifically, the support column 215 is a cylindrical structure, located on the axis of the turntable 213 and welded to the lower end of the turntable 213. The support block 211 has a fan-shaped structure, and an arc groove is provided at the center of the fan-shaped structure. Multiple support blocks 211 are arranged around the support column 215, and the multiple support blocks 211 are close to each other until they all abut against the support column 215. The arc grooves of the multiple support blocks 211 are all in contact with the support column 215, and the arc surface of the multiple arc grooves coincides with the peripheral surface of the support column 215. When the measuring device 10 is raised, the multiple support blocks 211 are used to slide in a direction away from the support column 215.

[0040] Thus, with the support column 215 installed at the lower center of the turntable 213, multiple support blocks 211 are evenly arranged around the support column 215 and in contact with the support column 215. The multiple support blocks 211 are used to slide in a direction away from the support column 215. In this way, when the multiple support blocks 211 move toward the support column 215 and come into contact with the support column 215, the support column 215 can limit the displacement of the multiple support blocks 211, so as to avoid the multiple support blocks 211 colliding with each other due to excessive displacement during the process of the multiple support blocks 211 approaching each other, thereby improving the reliability of the multiple support blocks 211.

[0041] Optionally, since the multiple support blocks 211 are all located at the lower end of the turntable 213, it is not easy for the operator to observe the proximity of the multiple support blocks 211 during actual use. Therefore, when the multiple support blocks 211 approach each other until they all abut against the support column 215, the support column 215 applies a reaction force to the multiple support blocks 211. This reaction force can be fed back to the operator through the drive structure 120, thereby facilitating the use of the building tilt and settlement measurement auxiliary positioning device.

[0042] Optionally, combined Figure 1 and Figure 2 As shown, the lifting drive assembly also includes a limiting post 130, one end of which is connected to the upper end of the base plate 110, and the other end extends above the first connecting rod 212 and is connected to the drive structure 120.

[0043] Specifically, the limiting post 130 is a cylindrical structure, and multiple limiting posts 130 are distributed along the edge of the base plate 110. The lower end of the limiting post 130 is connected to the upper end of the base plate 110, and the upper end of the limiting post 130 extends above the first connecting rod 212 and is connected to the drive structure 120.

[0044] Thus, by connecting one end of the limiting post 130 to the upper end of the base plate 110 and extending the other end above the first link 212 and connecting it to the drive structure 120, the limiting post 130 ensures that there is a certain distance between the base plate and the drive structure 120. In this way, when the first link 212 moves, interference between the drive structure 120 and the first link 212 can be avoided, thereby improving the moving efficiency of the first link 212.

[0045] Optionally, combined Figure 1 As shown, the drive structure 120 includes a column 121, a fixed base 122, and a fixed sleeve 129. The fixed base 122 is mounted on the base plate 110 and located above the first connecting rod 212. One end of the fixed sleeve 129 is fixed to the fixed base 122. One end of the column 121 is slidably connected to the fixed sleeve 129, and the other end extends out of the fixed sleeve 129 and is used to connect to the measuring instrument 10.

[0046] Specifically, the fixing seat 122 is located above the base plate 110. The fixing seat 122 can be a plate structure. The fixing seat 122 is parallel to the base plate 110 and connected by the limiting post 130. The fixing sleeve 129 is perpendicular to the fixing seat 122. The lower end of the fixing sleeve 129 is fixed to the fixing seat 122. One end of the column 121 is slidably connected to the fixing sleeve 129, and the other end extends out of the fixing sleeve 129 and is used to connect with the measuring device 10.

[0047] Thus, the fixed base 122 is installed on the base plate 110 and located above the first connecting rod 212. One end of the fixed sleeve 129 is fixed to the fixed base 122. One end of the column 121 is slidably connected to the fixed sleeve 129, and the other end extends out of the fixed sleeve 129 and is used to connect with the measuring device 10. This allows the height adjustment of the measuring device 10 to be achieved by the column 121 sliding on the fixed base 122. In this way, the moving accuracy of the measuring device 10 can be improved during the height adjustment process, so as to facilitate the use of the measuring device 10.

[0048] Optionally, combined Figure 1 , Figure 4 As shown, the drive structure 120 also includes a drive link 123 and a slider 124. A groove is provided on the fixed base 122. The slider 124 is slidably connected to the groove. The slider 124 is driven to be connected to the column 121 through the drive link 123. The bottom end of the slider 124 is driven to be connected to the first link 212 through the connector 20.

[0049] Specifically, the drive link 123 includes an upper link, a middle link, and a lower link. The middle link is located between the upper link and the lower link. The upper link and the middle link are of equal length. One end of the upper link and the middle link are hinged by a pin. The other end of the upper link and the middle link are respectively hinged to the column 121 and the fixed seat 122 by pins. One end of the lower link is hinged to the slider 124 by a pin, and the other end is hinged to the middle position of the middle link by a pin. The slide is composed of two parallel fixed plates 1221, which are welded to the upper end of the fixed base 122. The slider 124 is slidably connected between the two fixed plates 1221. In the sliding direction of the slider 124, the fixed base 122 is provided with an elongated hole. The length direction of the elongated hole is consistent with the sliding direction of the slider 124, and the width of the elongated hole is smaller than the width of the slider 124 (the dimension in the X-axis direction). The connecting member 20 is composed of a vertical rod and an L-shaped connecting rod. The L-shaped connecting rod is horizontal. The vertical rod is connected to the lower end of the slider 124 and to one side of the L-shaped connecting rod. The other side of the L-shaped connecting rod is connected to the first connecting rod 212. When adjusting the height of the measuring device 10, the slider 124 is pushed to slide between the two fixed plates 1221 toward the column 121. At the same time, the slider 124 drives the first connecting rod 212 to move away from the column 121 through the connector 20, thereby realizing that multiple support blocks 211 are simultaneously slid out from under the turntable 213 to be fixed on the ground.

[0050] Thus, the slider 124 is slidably connected to the groove provided on the fixed base 122, and is driven to the column 121 via the drive link 123. The bottom end of the slider 124 is driven to the first link 212 via the connector 20. In this way, during the adjustment of the height of the measuring device 10, the groove guides the movement of the slider 124, thereby improving the movement accuracy of the slider 124 and realizing the simultaneous adjustment of the height of the measuring device 10 and the movement of multiple support blocks 211. This facilitates the use of the building tilt and settlement measurement auxiliary positioning device.

[0051] Optionally, combined Figure 1 , Figure 4 and Figure 5 As shown, the drive structure 120 also includes a lead screw 125, a nut 126 and a transmission link 127. The lead screw 125 is parallel to the column 121 and located at the end of the slider 124 away from the column 121, and is rotatably connected to the fixed seat 122. The nut 126 is threadedly connected to the lead screw 125, and the transmission link 127 is hinged between the slider 124 and the nut 126.

[0052] Specifically, the lead screw 125 is set along the Z-axis, parallel to the column 121 and located at the end of the slider 124 away from the column 121, that is, the slider 124 is located between the column 121 and the lead screw 125. The lower end of the lead screw 125 is rotatably connected to the fixed seat 122 through a bearing seat. The nut 126 is threadedly connected to the lead screw 125. The transmission connecting rod 127 is hinged between the slider 124 and the nut 126 through a hinge shaft, and a handwheel can be installed at the upper end of the lead screw 125. When adjusting the height of the measuring device 10, the screw 125 is rotated by the handwheel. The screw 125 drives the nut 126 to move downward. The nut 126 pushes the slider 124 toward the screw 125 through the transmission link 127, so that the slider 124 pushes the column 121 upward through the drive link 123 to adjust the height of the measuring device 10. When the height of the measuring device 10 meets the requirements, the handwheel is released, and the height of the measuring device 10 is locked by the self-locking of the threaded connection between the screw 125 and the nut 126.

[0053] Thus, by having the lead screw 125 parallel to the column 121 and located at the end of the slider 124 away from the column 121, and rotatably connected to the fixed base 122, and the nut 126 threadedly connected to the lead screw 125, and the transmission link 127 hinged between the slider 124 and the nut 126, the sliding of the slider 124 is achieved by a self-locking drive structure composed of the lead screw 125, the nut 126 and the transmission link 127. In this way, the stability of the measuring instrument 10 can be improved after the height of the measuring instrument 10 is adjusted.

[0054] Optionally, such as Figure 1 As shown, the drive structure 120 also includes an adjustment seat 128, which is rotatably connected to the end of the column 121 away from the fixed seat 122, and is used to rotatably connect with the measuring instrument 10.

[0055] Specifically, the adjusting seat 128 includes two parallel mounting plates and a rotating seat welded between the two mounting plates. The rotating seat is rotatably connected to the upper end of the column 121 via a rotating shaft, bearing, or other alternative means, so that the adjusting seat 128 rotates around the axis of the column 121 in the XY plane. The measuring instrument 10 is rotatably mounted between the two mounting plates via a rotating shaft. During measurement, the horizontal swing angle of the measuring instrument 10 can be adjusted by rotating the adjusting seat 128 relative to the column 121, and the elevation angle of the measuring instrument 10 can also be adjusted by rotating the measuring instrument 10 relative to the adjusting seat 128.

[0056] Thus, by rotatably connecting the adjusting seat 128 to the end of the column 121 away from the fixed seat 122, and using it to rotatably connect with the measuring device 10, the measuring device 10 can be rotated horizontally or vertically, thereby improving the flexibility of the measuring device 10.

[0057] Optionally, such as Figure 1As shown, the drive structure 120 also includes a locking element, which is adapted to limit the relative rotation between the adjusting seat 128 and the column 121.

[0058] Specifically, as mentioned above, the locking element can be a bolt. Both the adjusting seat 128 and the column 121 are provided with threaded holes. During measurement, according to the actual measurement requirements, after rotating the adjusting seat 128 to the required position, the bolt connects the adjusting seat 128 and the column 121 through the threaded holes.

[0059] Optionally, the locking element can also be adapted to limit the relative rotation between the adjusting seat 128 and the measuring device 10, in the same principle as limiting the relative rotation between the adjusting seat 128 and the column 121.

[0060] Thus, by using a locking element to restrict the relative rotation between the adjusting seat 128 and the column 121, the stability of the measuring instrument 10 during measurement can be improved, thereby increasing the measurement accuracy.

[0061] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
