Description

Technical Field

[0001] The present invention relates to the technical field of portable laser projection positioning devices, and particularly to a portable laser projection positioning device. Background Art

[0002] In the field of enterprise production, the construction of new factories and the expansion of reproduction are indispensable. The construction of factories includes the construction of main factories, the construction of internal facilities, and the construction of internal facilities includes the laying of power cable trays, the laying of water, gas and pipeline, fire-fighting facilities, the laying of air-conditioning ducts, the construction of various-purpose rooms in the factory building, the construction of partition walls, the installation of all equipment related to production, the installation of lighting systems, network systems, and so on.

[0003] Currently, in the process of factory building construction, the relationships between various components in the factory building are mostly displayed in a two-dimensional plane using AutoCAD drawing software, and the absolute and relative dimensions of the positions between any objects can be marked in the two-dimensional plane. The main columns of the factory building are usually designated as the reference positions, such as the R axis in the longitudinal axis direction (named in the front-back direction), the 5 axis in the transverse axis direction (named in the left-right direction), etc. Other secondary columns built later in the factory building are referenced with the reference columns of the main factory building, and are shifted a certain number of millimeters to the left, right, forward, or backward to the secondary columns, so as to facilitate the later installation of wall panels on the secondary columns, and also facilitate the later installation of power cable trays, water and gas pipelines, fire-fighting water pipelines, air-conditioning ducts, etc. on the top of the wall panels. Since components such as power cable trays, water and gas pipelines, fire-fighting water pipelines, air-conditioning ducts, etc. cannot fully display the installation dimensions and positions on the drawings, it is necessary to actually measure the specific position dimensions on site. Currently, most of the measurement methods use a tape measure, centered on the main column, and measure around to ensure the installation of the wall panel, and at the same time prevent the installation position of the wall panel from affecting the subsequent installation of power cable trays and fire-fighting water pipelines. However, this method will have the following problems.

[0004] Since the above-mentioned measurement is carried out using a tape measure, and then the fixed position of the wall panel and the secondary column is calculated through the length, width, and height, most of this kind of measurement is carried out by workers, and deviations will occur during the measurement process, which is likely to cause deviations when the wall panel is installed, and further likely to cause problems such as inconvenient installation during the later installation of power cable trays, fire-fighting water pipelines, etc. Summary of the Invention

[0033] Embodiment 2

[0034] As Figures 1-9 shown, on the basis of the above embodiment, the following content is further given in this embodiment:

[0035] The auxiliary measurement component 5 includes a measuring rod 51. A clamping groove 52 is arranged in the middle of one side of the measuring rod 51. A bidirectional threaded rod 53 is rotatably connected to the inner cavity of the clamping groove 52. Moving blocks 54 are respectively threadedly connected to both ends of the outer surface of the bidirectional threaded rod 53.

A first jack 59 is arranged on one side of the moving block 54. Second jacks 510 are respectively arranged at both ends of the measuring rod 51. Clamping grooves 511 are respectively arranged at both ends of one side of the measuring rod 51. One end of the plug board 58 is respectively inserted and matched with the inner cavities of the first jack 59 and the second jack 510. A protrusion 512 is fixed at one end of the clamping plate 55. A vertical rod 513 is rotatably connected to the middle of the front end face of the measuring rod 51.

[0036] By expanding the auxiliary measurement component 5, the center position of the main column can be found, and at the same time, the fixation of the auxiliary measurement component is realized, which facilitates the measurement and positioning of the projection component in the later stage.

[0037] The working principle and usage process of the present invention:

[0038] In the usage state:

[0039] When measuring by the first method:

[0040] First, pull the plug board 58 so that the plug board 58 slides in the inner cavity of the socket groove 56. When the plug board 58 slides, one end of the plug board 58 will squeeze the damping rod 57 at this time. Since a spring is sleeved outside the damping rod 57, the spring will be compressed. When the plug board 58 slides, at this time, one end of the plug board 58 will be disengaged from the inner cavity of the second jack 510. During the disengagement, the clamping plate 55 will rotate around the moving block 54 at this time. When the clamping plate 55 rotates to be on the same horizontal plane as the moving block 54, then release the plug board 58. The plug board 58 will be reset under the action of the damping rod 57 and the spring outside it. After resetting, one end of the plug board 58 will be inserted into the first jack 59. After insertion, at this time, the staff can place the clamping plates 55 on both sides of the main column 4 respectively. After placing them stably, start to rotate the bidirectional threaded rod 53. When the bidirectional threaded rod 53 rotates, it will drive the clamping plates 55 to move relatively. When the clamping plates 55 move relatively, the measuring rod 51 can be fixed on the main column 4. After fixing, at this time, rotate the vertical rod 513. When the vertical rod 513 rotates 90 degrees, the vertical rod 513 will form a cross state with the measuring rod 51 at this time. After rotation, at this time, rotate the parallel rod 514 in the vertical rod 513 out, and then make the parallel rod 514 perpendicular to the vertical rod 513 by 90 degrees. After perpendicularity, one side of the parallel rod 514 will also contact the ground;

[0041] After installation, since the bottom plate 1 is made of iron, the laser pointer 634 will be activated at this time. Then the staff can move the laser pointer 634 so that the laser emitted by the laser pointer 634 can shine on the second wire groove 519. After determining the initial position, the entire projection assembly 6 is placed on the bottom plate 1 at one end of the parallel rod 514. After placement, the magnet 615 at the lower part of the support foot 614 will attract to the bottom plate 1. After attraction, the entire projection assembly 6 will be fixed by the magnet 615. After fixation, the circular bubble level 624 is observed at this time. If it is found that the horizontal bubble is not located in the middle of the circular bubble level 624, the threaded sleeve 612 is rotated at this time. The threaded sleeve 612 will drive the height threaded rod 613 to move up or down. As the height threaded rod 613 rises or falls, the entire projection assembly 6 will be in a horizontal state. After being in a horizontal state, it is observed whether the laser emitted by the laser pointer 634 is on the same horizontal plane as the first wire groove 518. If not, the moving threaded rod 622 is rotated at this time. When the moving threaded rod 622 rotates, it will drive the transverse movement plate 623 and the measuring assembly 63 to move until the light irradiated by the laser pointer 634 coincides with the first wire groove 518. After coincidence, it is observed whether the light spot irradiated by the laser pointer 634 is located at both ends of the second wire groove 519. If not, the laser pointer 634 is rotated and observed again until the light spot irradiated by the laser pointer 634 can coincide with both ends of the second wire groove 519. If it coincides and the light of the laser pointer can also coincide with the first wire groove 518, the installation and positioning of the projection assembly 6 are completed. After positioning, the laser pointer 634 is operated at this time so that the light spot of the laser pointer 634 shines on the wall panel 3, and the light spot is recorded on the wall panel 3. Then, through the auxiliary measuring assembly, it can be extended to the secondary columns 2 on both sides on the wall panel 3, so as to facilitate drilling on the secondary columns 2 in the later stage to fix the wall panel 3 thereto, or facilitate the installation of the cross beam in the later stage.

[0042] The second measurement method:

[0043] First, adopt the same steps as the above first measurement method. Fix the measuring rod 51 on the main column 4 through the clamping plate 55. After fixing, then rotate the vertical rod 513. After rotating the vertical rod 513 by 90 degrees, at this time, make the vertical rod 513 form a cross shape with the main column 4. After forming, thread-connect one end of the mercury mirror 516 with the mounting hole 515 in the parallel rod 514. After the thread connection, then start the laser pen 634 so that the laser on the laser pen 634 irradiates on the mercury mirror 516. Then, check whether the reflected light is coincident with the irradiated light through the reflection of the mercury mirror 516. After coincidence, place the projection assembly 6 as a whole on the bottom plate 1. After placing, fix the projection assembly 6 through the magnet 615. Then, use the horizontal assembly 61 and the translation assembly 62 to adjust the laser pen 634 so that the irradiated light and the reflected light are re-aligned, thus completing the installation of the projection assembly 6. After the installation is completed, rotate the angle so that the light on the laser pen 634 irradiates on the wall panel 3. After irradiation, mark on the wall panel 3 at this time, then use the auxiliary measurement assembly to draw a line and extend the line to the secondary column 2. After extension, it is convenient to drill holes on the secondary column 2 later, and it is also convenient to fix the wall panel 3 later, or install a reinforcing rib, etc.

[0044] When the auxiliary measurement assembly 5 is used up, first rotate the parallel rod 514 into the vertical rod 513. After rotation, then rotate the vertical rod 513 by 90 degrees so that the vertical rod 513 coincides with the measuring rod 51. After coincidence, rotate the bidirectional threaded rod 53. When the bidirectional threaded rod 53 rotates, it will drive the moving block 54 and the clamping plate 55 to move to both ends of the clamping groove 52. At this time, pull the plug board 58 so that the plug board 58 disengages from the first jack 59. After disengagement, rotate the clamping plate 55. When the clamping plate 55 rotates by 90 degrees, it will be limited and stuck by the clamping groove 511. At the same time, the protrusion 512 at one end of the clamping plate 55 starts to enter the groove 517. After entering, at this time, the parallel rod 514 can be limited and fixed by the protrusion 512 at one end of the clamping plate 55 cooperating with the groove 517, thus preventing the parallel rod 514 and the vertical rod 513 from rotating. At this time, loosen the plug board 58, and the plug board 58 will be fixed at both ends of the measuring rod 51 under the action of the damping rod 57, thereby increasing the length of the measuring rod 51. At the same time, this device will also be convenient for the staff to draw lines, etc. later.

Unfolding and clamping fixation of the auxiliary measuring component: Rotate the clamping block and fix it to the moving block through the inserting plate; Drive the clamping plates to move relative to each other through the bidirectional threaded rod, and make them located on both sides of the main column to complete the clamping fixation; Rotate the vertical rod so that the vertical rod and the measuring rod form a "cross shape"; Rotate the parallel rod so that the parallel rod is perpendicular to the vertical rod at 90 degrees; S2. Positioning of the projection component: Place the projection component in front of the parallel rod and observe whether it is horizontal through the circular spirit level; When it is not in a horizontal state: Adjust the height and level of the laser pen through the cooperation of the height threaded rod and the threaded sleeve; Turn on the laser pen and check whether the light ray coincides with the first wire groove; at the same time, also check whether the light spot coincides with the points at both ends of the second wire groove; If they do not coincide, realize left and right translation through the translation component to ensure that the light ray coincides with the first wire groove, and rotate the laser pen up and down to ensure that the light spot coincides with the points at both ends of the second wire groove; S3. Reverse measurement: Rotate the laser pen in the reverse direction by a certain angle so that the light spot shines on the wall panel and make a mark, and then draw a line along the marked point and extend it to the secondary column for convenient hole punching in the later stage.
