Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, and particularly to a verticality detection device for construction projects. Background Art

[0002] Verticality detection in construction engineering quality inspection is an important link in construction engineering quality control, mainly focusing on the vertical situation of buildings or structures. Verticality detection refers to measuring the deviation degree of a building or structure in the vertical direction, that is, checking whether it is in a vertical state as required by the design. Verticality directly affects the structural stability of a building. When the verticality of a building does not meet the standard, it will lead to a weakened load-bearing capacity of the building, posing a potential threat to the structural safety of the building. Secondly, verticality also affects the aesthetic appearance of a building, and a building with poor verticality will give people a feeling of tilt and distortion, affecting the overall aesthetic appearance.

[0003] Traditional verticality detection devices usually use a plumb bob for measurement. Specifically, a plumb line is installed at the center position of the top of the plumb bob, and then the top of the plumb line is fixed to the alignment position with the top of the facility to be measured, and the plumb line is tightened; in this process, it is necessary to keep the plumb bob stationary. However, in the actual detection process, there will inevitably be wind force outdoors. Under the action of the wind force, the plumb bob is prone to shaking, thereby affecting the detection accuracy. Therefore, the present invention provides a verticality detection device for construction projects. Summary of the Invention

The drawings in the present invention are not drawn strictly according to actual proportions, and the specific dimensions and quantities of each structure can be determined according to actual needs. The drawings described in the present invention are only schematic diagrams of the structure.

[0021] The verticality detection device for construction projects provided by the present invention includes a plumb bob 1 and a plumb line 2 fixed to the center of the top end of the plumb bob 1. It also includes a support platform 3. A circular limit groove 4 is opened at the top of the support platform 3. A clamping assembly 5 for clamping the plumb bob 1 is arranged in the circular limit groove 4. The clamping assembly 5 includes a support tube 51, which is horizontally arranged in the circular limit groove 4 and fixedly connected to the support platform 3. A plurality of support tubes 51 are provided, and the plurality of support tubes 51 are arranged in an array along the axis of the circular limit groove 4. A moving rod 52 is slidably embedded in each of the plurality of support tubes 51 in a one-to-one correspondence. One end of each of the plurality of moving rods 52 is fixedly connected to a clamping plate 53. A cavity 6 is arranged in the support platform 3, and a driving assembly 7 is arranged in the cavity 6. The driving assembly 7 is used to drive the moving rod 52 to move in the support tube 51.

[0022] When the device designed by the present invention is in use, first, the plumb line of the plumb bob 1 is installed at the top of the wall to be detected, so that the plumb bob 1 moves vertically downward to pull the plumb line of the plumb bob 1, and the plumb bob 1 is placed in the circular limit groove 4 opened on the support platform 3. The plurality of moving rods 52 arranged move in the support tubes 51. The clamping plates 53 arranged at the top ends of the moving rods 52 will closely adhere to the side surface of the plumb bob 1. The plumb bob 1 is stably clamped by the plurality of clamping plates 53, thereby avoiding the problem that the plumb bob 1 is prone to shaking under the action of wind outdoors, which in turn affects the detection accuracy.

[0023] Preferably, an infrared emitter 10 is fixedly arranged at the center of one end of the plumb bob 1. A through hole 11 is provided on the support platform 3, and the axis of the through hole 11 coincides with the axis of the annular limiting groove 4. A light plate 12 is horizontally arranged at the bottom of the support platform 3, and the light plate 12 is fixedly connected to the support platform 3 through a support rod 13.

[0024] In the present invention, a plurality of support rods 13 are fixedly connected to the bottom of the support platform 3, and the light plate 12 is horizontally supported by the plurality of support rods 13. A through hole 11 is opened on the support platform 3, and the axis of the through hole 11 coincides with the axis of the annular limiting groove 4. Due to the uncertainty of the plumb bob 1 when it falls, it cannot be guaranteed that the axis of the plumb bob 1 coincides with the axis of the annular limiting groove 4 when the plumb bob 1 is placed in the annular limiting groove 4. At this time, the position of the support platform 3 needs to be adjusted. When the infrared rays emitted by the infrared emitter 10 provided at the bottom end of the plumb bob 1 pass through the through hole 11 and are projected onto the light plate 12, it proves that the axis of the plumb bob 1 coincides with the axis of the annular limiting groove 4 at this time. By making the clamping forces in all directions of the clamping assembly 5 the same, the plumb bob 1 can be stably clamped, avoiding the influence of the clamping forces in all directions during the clamping process and causing the plumb bob 1 to tilt.

[0025] Preferably, the driving assembly 7 includes an annular storage cavity 71, an air pump 72 and an airbag 73. The annular storage cavity 71 is arranged in the cavity 6 and fixedly connected to the support platform 3. The airbag 73 is annularly arranged in the annular storage cavity 71, and the axis of the annular storage cavity 71 coincides with the axis of the annular limiting groove 4. A plurality of air pumps 72 are provided, and the plurality of air pumps 72 are arranged in an array along the axis of the annular storage cavity 71 at the top end of the support platform 3. The output end of the air pump 72 is connected to the air inlet end of the airbag 73. One end of the moving rod 52 is placed in the cavity 6 and fits with the airbag 73.

[0026] In the present invention, the driving assembly 7 is arranged on the support platform 3. The annular storage cavity 71 is arranged in the cavity 6, and a plurality of air pumps 72 are arranged on the support platform 3. The plurality of air pumps 72 are arranged in an array along the axis of the annular storage cavity 71 at the top end of the support platform 3 to ensure that all parts of the annular airbag 73 can be inflated simultaneously. After the plumb bob 1 is adjusted to coincide with the axis of the annular limiting groove 4, the provided air pump 72 is started to inflate the airbag 73. When the airbag 73 expands, it squeezes the provided moving rod 52 and gives power to the moving rod 52. In the present invention, the annular airbag 73 and the air pump 72 cooperate. When the annular airbag 73 expands, it can quickly push the moving rods 52 arranged in an array along the axis of the annular limiting groove 4, so that the pushing forces received by the respective moving rods 52 are the same, thereby stably limiting the plumb bob 1 at the center and avoiding the mutual influence of the pushing forces of the respective moving rods 52.

[0027] Preferably, a contact plate 8 is fixedly connected to one end of the moving rod 52 close to the airbag 73. A return spring 9 is sleeved on the moving rod 52. One end of the return spring 9 is fixedly connected to the contact plate 8, and the other end is fixedly connected to the support platform 3. The clamping plate 53 is arranged in an arc shape and is made of deformable rubber material.

[0028] In the present invention, the moving rod 52 abuts against the airbag 73 through the contact plate 8, and a return spring 9 is sleeved on the moving rod 52. After a measurement is completed, the air pump 72 pumps the air in the airbag 73 out, and the airbag 73 shrinks after deflation. At this time, the compressed return spring 9 will pull the moving rod 52 back to its original position for subsequent reuse. The clamping plate 53 in the present invention is arranged in an arc shape and is made of deformable rubber material, which can better fit the surface of the plumb bob 1 and better stably clamp the plumb bob 1.

[0029] Preferably, it further includes a base 14. An adjusting component 15 is provided on the base 14. The adjusting component 15 is used to adjust the position of the support platform 3. The adjusting component 15 includes a first sliding groove 151 and a second sliding groove 155. The axes of the first sliding groove 151 and the second sliding groove 155 are perpendicular. The first sliding groove 151 is fixedly arranged on the base 14. A first adjusting screw 152 is arranged in the first sliding groove 151. One end of the first adjusting screw 152 is rotatably connected to the first sliding groove 151, and the other end is fixedly connected to a first rotating handle 154. A first sliding block 153 is threadedly sleeved on the first adjusting screw 152. The first sliding block 153 is slidably arranged in the first sliding groove 151. The second sliding groove 155 is fixedly connected to the top end of the first sliding block 153. A second adjusting screw 156 is arranged in the second sliding groove 155. One end of the second adjusting screw 156 is rotatably connected to the second sliding groove 155, and the other end is fixedly connected to a second rotating handle 158. A second sliding block 157 is threadedly sleeved on the second adjusting screw 156. The second sliding block 157 is slidably arranged at the top end in the second sliding groove 155 and is fixedly connected to the bottom of the light plate 12. First lifting rods 16 are fixedly connected to the bottom corners of the base 14. A second lifting rod 17 is slidably sleeved on the outside of the first lifting rod 16. A cylinder 18 is vertically arranged in the second lifting rod 17. The output end of the cylinder 18 is fixedly connected to the first lifting rod 16. A seat plate 19 is fixedly connected to the bottom end of the second lifting rod 17. A level gauge is embedded on the base 14.

[0030] In the present invention, when it is necessary to align the plumb bob 1 with the axis of the annular limiting groove 4, the position of the support platform 3 needs to be adjusted by the adjusting assembly 15. By rotating the first rotating handle 154 provided, the first threaded rod is rotated, so that the provided first moving block 153 slides in the first sliding groove 151, thereby driving the second sliding groove 155 by the first sliding block 153 to move along the direction of the first sliding groove 151. By rotating the second rotating handle 158 provided, the second threaded rod is rotated, so that the provided second moving block 157 slides in the second sliding groove 155, thereby driving the light plate 12 by the second sliding block 157 to move along the direction of the second sliding groove 155, so as to adjust the horizontal position of the support platform 3 on the top of the light plate 12.

[0031] The usage method of the verticality detection device for construction projects of the present invention is as follows:

[0032] The base 14 provided is supported by the base plate, and the first lifting rod 16 provided is pushed by the cylinder 18, so that the first push rod slides vertically in the second push rod. The base 14 is adjusted according to the placement position. The plumb bob 1 line is installed at the top of the wall to be detected, and the plumb bob 1 vertically moves downward to pull the plumb bob 1 line, and the plumb bob 1 is placed in the annular limiting groove 4 opened on the support platform 3;

[0033] Rotate the first rotating handle 154 provided to rotate the first threaded rod, so that the provided first moving block 153 slides in the first sliding groove 151, thereby driving the second sliding groove 155 by the first sliding block 153 to move along the direction of the first sliding groove 151. By rotating the second rotating handle 158 provided, the second threaded rod is rotated, so that the provided second moving block 157 slides in the second sliding groove 155, thereby driving the light plate 12 by the second sliding block 157 to move along the direction of the second sliding groove 155, so as to adjust the horizontal position of the support platform 3 on the top of the light plate 12. When the infrared rays emitted by the infrared emitter 10 provided at the bottom end of the plumb bob 1 pass through the through hole 11 and are reflected on the light plate 12, it proves that the plumb bob 1 coincides with the axis of the annular limiting groove 4 at this time;

[0034] Start the air pump 72 provided to inflate the airbag 73. When the airbag 73 expands, it squeezes the moving rod 52 provided, giving power to the moving rod 52. In the present invention, the annular airbag 73 cooperates with the air pump 72. When the annular airbag 73 expands, it can quickly push the moving rods 52 arranged axially in the annular limiting groove 4.
