Description

Technical Field

[0001] The invention relates to the technical field of verticality detection devices, and in particular to a verticality detection device for communication engineering supervision. Background Art

[0002] At present, with the rapid development of communication technology, communication towers, as important infrastructure supporting communication networks, their construction quality and maintenance level are directly related to the stability and security of communication networks. During the construction and operation of communication towers, verticality detection is one of the key links to ensure the stability of the tower structure and prevent tilting and collapse. Long-distance measurement equipment such as total stations in existing technologies are more convenient to use, but are not accurate enough in determining the center due to the influence of distance.

[0003] After searching, it was found that the Chinese utility model patent with authorization announcement number CN216206089U discloses a detection device for monitoring the verticality of communication towers based on wind pressure status. The patent uses a base to fix the communication tower and realizes verticality detection through a mechanical structure in the storage bin. Its core is the combination of the adjustment plate on the slide and the control box, and the horizontal adjustment component and the elastic tensioning element are used to ensure accuracy. The control box is detachable, which is convenient for multi-tower detection and reduces costs. The device intuitively displays the vertical state and is easy to operate. It can quickly measure and calculate the inclination; however, the patent requires the equipment to be fixed on the communication tower. Each communication tower needs to be equipped with the equipment when it needs to be detected, which has great limitations and cannot reduce costs. At the same time, it can only measure two points of the bottom axis position and the top axis position, and the data obtained is not accurate. Summary of the invention

[0087] like Figure 4 As shown, the driving device includes a rotating disk 102, a driving bevel gear 103 and two driven bevel gears 104, the rotating disk 102 is connected to the driving bevel gear 103, the two driven bevel gears 104 are meshed with the driving bevel gear 103, one end of the two driven bevel gears 104 is respectively connected to a threaded rod 105, two support plates 106 are respectively assembled on the outside of the corresponding threaded rod 105 through ball nuts, and the rotating disk 102 is suitable for driving the threaded rod 105 to rotate to drive the support plate 106 to move;

[0088] For a hollow communication tower, the two support plates 106 are suitable for moving backwards to contact the inner circumference of the communication tower at the maximum diameter at the bottom.

[0089] The working principle of this embodiment is as follows:

[0090] When testing the verticality of a hollow communication tower, for a hollow communication tower, place the entire device in the middle of the hollow space of the communication tower, rotate the turntable 102 to drive the active bevel gear 103 and the driven bevel gear 104 to engage, thereby realizing the rotation of the threaded rod 105, so as to drive the two support plates 106 to expand to both sides of the entire device, and after expansion, support the maximum diameter of the communication tower. At this time, the initial position of the laser emitting assembly 6 is located at the center of the diameter of the communication tower base and the 0 scale line position of the scale bar 1 404 and the scale bar 2 504. 606 is set perpendicular to the horizontal plane and emits laser upward. When the laser touches the top of the communication tower, it is reflected back to the transmitter 606 and received by the laser receiving device inside the transmitter 606. The received optical information is then displayed on the control panel 605 to show the distance from the transmitting center to the top of the tower. The straight-line distance from the initial position of the transmitter 606 to the top of the tower is compared and calculated with the straight-line height set in the design drawing of the communication tower to determine whether it is within the allowable error range, so as to determine whether it is vertical or not. If it is not vertical, its inclination can also be calculated.

[0091] When it is not vertical, in order to ensure that the calculated inclination is more accurate, the inner diameter of the bottom of the communication tower is used as the reference plane, and the inner diameter of the top of the communication tower is used as the reference plane. The above method controls the laser emitting assembly 6 at the center position of the inner diameter of the communication tower, and the laser emitting assembly 6 emits the laser vertically upward to the reference plane on the top of the communication tower;

[0092] When the communication tower is in a vertical state, the center line of the datum plane and the center line of the reference plane should be roughly on the same axis, and the length of each radius around the center of the reference plane should be the same;

[0093] However, when the communication tower is in a tilted state, the center lines of the reference surface and the reference surface are not on the same axis. At this time, the laser emitted by the laser emitting assembly 6 located at the center of the reference surface will hit the position of the reference surface that deviates from the center line. The distance to each side of the reference surface calculated with this position as the center point will produce a deviation, rather than the original reference surface radius.

[0094] The laser emitting assembly 6 can be adjusted by moving the X and Y axes according to the actual size of the reference surface, so as to calculate the length from the center point of the reference surface to each edge of the reference surface in the above-mentioned tilted state. From this length, it can be determined whether the communication tower is vertical. If it is not vertical, the inclination can also be calculated from the known information, and the obtained inclination value is more accurate.

[0095] When the laser emitting assembly 6 needs to move in the X-axis direction, the driving motor 1 402 is started to drive the threaded rod 2 403 to rotate, so that the mobile platform 405 can move along the direction of the thread. When moving, the Y-axis adjustment and the laser emitting assembly 6 above it can be driven to achieve displacement in the X-axis direction. After adjusting the position, the mobile platform 405 and the X-axis adjustment plate 401 can be fixed by nuts, and the distance moved in the X-axis direction can be intuitively displayed by the scale bar 1 404;

[0096] When the laser emitting assembly 6 needs to move in the Y-axis direction, the second driving motor 505 is started to drive the threaded rod 3 506 to rotate, so that the placement table 507 moves along the direction of the thread. When moving, the laser emitting assembly 6 above it will be driven to achieve displacement in the Y-axis direction as a whole. The distance moved in the Y-axis direction can be intuitively displayed by the second scale bar 504;

[0097] It should be noted that the key to this part is to support the inner wall of the communication tower by synchronously moving the two support plates 106. Since the two support plates 106 move synchronously outward from the center of the device, and the laser emitting assembly 6 is located at the center of the two support plates 106, it can be ensured that the laser emitting assembly 6 is located at the center of the inner diameter of the bottom of the communication tower. At the same time, the scale of the scale bar 1 404 and the scale bar 2 504 can assist the initial position of the laser emitting assembly 6 to be located at the 0-position line and the center of the inner diameter of the bottom of the communication tower. The support accuracy and stability of this part of the support plate 106 for the inner wall of the communication tower are particularly important;

[0098] The inner wall of the communication tower is not a standard straight line, but is mostly inclined, which is more conducive to supporting the entire communication tower. Therefore, when the support plate 106 supports the inclined inner wall, the inclination adjustment component 2 needs to cooperate. When the support plate 106 is extended, the movable plate 201 movably hinged at one end thereof will contact the inner wall of the communication tower. After contact, the movable plate 201 is squeezed by the inner wall and automatically adjusts the angle according to the inclination of the inner wall to support the inner wall. This setting improves the support accuracy.

[0099] After the movable plate 201 supports the inner wall, since the communication tower is hollowed out, the positioning frame 202 can pass through the hollowed-out part, and then the docking plate 203 is inserted into the interior of the positioning frame 202. Both the docking plate 203 and the movable plate 201 are provided with docking holes 204. The docking plate 203 and the movable plate 201 can be fixed to the movable plate 201 by tightening bolts through the docking holes 204. At the same time, the docking plate 203 will move toward the direction of the movable plate 201, thereby achieving the effect of clamping and fixing the inner and outer sides of the communication tower. This part improves the stability of the equipment and is more conducive to subsequent work.

[0100] Embodiment 2: Figure 6As shown, this embodiment further includes the following structure on the basis of the first embodiment: it also includes a diameter adjustment component 3, the diameter adjustment component 3 includes two groups of special-shaped components and an adjustment rod 302, the special-shaped component includes two special-shaped blocks 301, one of the special-shaped blocks 301 is connected to one of the support plates 106, the inside of the other special-shaped block 301 passes through the adjustment rod 302 and is connected to the other special-shaped block 301, the outer peripheral surface of the adjustment rod 302 is provided with an external thread, the inside of one of the special-shaped blocks 301 is provided with an internal thread, the adjustment rod 302 is suitable for changing the spacing between the two special-shaped blocks 301, the external thread of the adjustment rod 302 is connected to two diameter fixing nuts 303, and the two diameter fixing nuts 303 are suitable for fixing the two ends of the other special-shaped block 301;

[0101] Both of the two special-shaped blocks 301 are provided with inclined surfaces, and the special-shaped blocks 301 are suitable for fixing the outer diameter of the bottom of the cylindrical communication tower.

[0102] The working principle of this embodiment is as follows:

[0103] In addition to the hollow communication towers, there are also communication towers that are supported only by a single support column. For this type of communication tower, another detection method is required. Since there is no space in the support column of the communication tower to accommodate the equipment, the detection equipment needs to be placed outside the communication tower.

[0104] First, it is still necessary to place the laser emitting assembly 6 at the center position of the bottom of the communication tower. At this time, it is necessary to install the diameter adjustment assembly 3 on one side of the support plate 106. The diameter of the communication tower support column is clamped and positioned by the diameter adjustment assembly 3 to determine the diameter size of the support column. Since the laser emitting assembly 6 is located at the center position of the two clamping support column components, and the two clamping support column components move synchronously to both sides with the laser emitting assembly 6 as the starting point, after the diameter adjustment assembly 3 clamps the support column of the communication tower, it can be ensured that the laser emitting assembly 6 can be located at the center position of the support column diameter;

[0105] The diameter adjustment components 3 are divided into two groups, which are respectively fixed on the corresponding support plates 106 and move with the support plates 106. Each group is provided with two special-shaped blocks 301. The spacing between the special-shaped blocks 301 is adjusted by adjusting rods 302, so that the special-shaped blocks 301 fix the support columns more stably.

[0106] During the adjustment process, one of the special-shaped blocks 301 is sleeved on the adjustment rod 302, and the adjustment rod 302 is screwed into the inside of the other special-shaped block 301 through threaded matching until the required spacing between the two special-shaped blocks 301 is adjusted. After the spacing is adjusted, the position of the special-shaped block 301 that was originally loosely sleeved on the adjustment rod 302 is fixed by two diameter fixing nuts 303;

[0107] After the diameter adjustment assembly 3 is adjusted, it can be installed on the corresponding support plate 106. The two sets of diameter adjustment assemblies 3 can be moved by rotating the turntable 102 until the support column of the communication tower is clamped. At this time, the laser emission assembly 6 is located at the center of the support column.

[0108] It should be noted that, since the detection equipment is now entirely outside the communication tower, the original position of the Y-axis moving plate 503 will interfere with the support column of the communication tower, so the Y-axis adjustment assembly 5 needs to be moved as a whole, and after the movement, it is fixed to the connecting plate 501 through the Y-axis fixing nut 502, such as Fig.15 As shown;

[0109] After adjustment, the laser emitting assembly 6 is adjusted by rotating the vertical control screw 608 and the horizontal control screw 609 to adjust the longitudinally rotatable transmitter 606 and the horizontally rotatable upper base 603 so as to align the objective lens 610 with the support column of the communication tower, thereby obtaining the distance between the objective lens 610 and the center position of the support column, and then rotating the vertical control screw 608 and the horizontal control screw 609 to align the objective lens 610 with the top of the communication tower to obtain the oblique distance from the objective lens 610 to the top of the tower. The lengths of the two sides can be obtained by the straight-line distance from the objective lens 610 to the support column and the oblique distance to the top of the tower, and then the straight-line distance from the center of the support column to the top of the tower can be calculated by calculation, and compared with the standard size on the design drawing, that is, whether the difference between the two is within the threshold range, it can be known whether it is vertical, and at the same time, the laser emitting assembly 6 can still be adjusted in the X-axis direction in the above manner, and multiple points can be measured to ensure the accuracy of the data;

[0110] It should be noted that the objective lens 610 on the transmitter 606 is used to align with the position to be measured, the eyepiece is the position where the operator's eyes observe, the curved tube eyepiece 607 can facilitate the operator to observe from multiple angles, and the eyepiece is set as a telescope, which is on the same axis as the position of the laser emission, so that the operator can emit the laser at the position to be measured. The vertical control screw 608 for the transmitter 606 and the horizontal control screw 609 for the upper base 603 are all existing technologies and will not be elaborated on here.

[0115] like Figure 11-14 As shown, it also includes a support assembly 8, the support assembly 8 includes a fixing block 801 and at least three supporting feet 802, and the fixing block 801 is connected to the bottom of the housing 101;

[0118] Both sides of the telescopic plate 805 are connected to limit blocks 810, and the two limit blocks 810 are slidably connected to the inside of the bracket 804. The inside of the two limit blocks 810 is provided with threaded holes penetrating through the two limit blocks, and the bracket 804 is provided with transverse grooves penetrating through the two limit blocks at positions corresponding to the threaded holes. The threaded holes and the transverse grooves are suitable for passing bolts and tightening nuts to fix the limit blocks 810;

[0119] A balancing assembly 9 is provided at the bottom of the telescopic plate 805. The balancing assembly 9 includes a movable shaft 901 and a flat plate 903. The movable shaft 901 is rotatably mounted at the bottom of the telescopic plate 805. The flat plate 903 is fixedly sleeved on the outside of the movable shaft 901. The movable shaft 901 partially extends out of the telescopic plate 805. An external thread is provided on the outer peripheral surface of the extended portion. A locking nut 902 is threadedly connected to the external thread. The locking nut 902 is suitable for rotating and tightening to limit the rotation of the movable shaft 901.

[0120] A plurality of springs 904 are connected to the interior of the plane plate 903, and the bottoms of the plurality of springs 904 are respectively connected to balance plates 905, and both ends of the plurality of balance plates 905 are connected to guide plates 906. A plurality of guide grooves corresponding to the guide plates 906 are provided inside the plane plate 903, and the guide plates 906 are slidably connected inside the guide grooves. The plurality of balance plates 905 are suitable for being individually retracted and adjusted according to the flatness of the ground.

[0121] The working principle of this embodiment is as follows:

[0122] When testing a hollow communication tower, the laser is emitted vertically to the top of the tower. The top surface of the tower can partially block the direct light from the top of the laser emission assembly 6, but the side light will still interfere with the laser emission. When testing a communication tower with a support column in the middle, the transmitter 606 is tilted and there is no shielding on the top. Therefore, it will be interfered by both the direct light from the top and the side light.

[0123] In the case of strong light interference, the outer light shielding cover 71 can be connected to the outside of the objective lens 610 through the cooperation of the outer thread of the objective lens 610 and the inner thread of the light shielding component 7 to play a role of protection and light shielding;

[0124] The inner part of the outer light shield 71 is connected to the inner light shield 72 by magnetic attraction of the positive magnet 711 and the negative magnet 725. The outer light shield 71 is provided with a sealing ring 712. The connecting portion 724 in the docking ring 722 provided on the inner light shield 72 can be directly inserted into the sealing ring 712 to achieve sealed plug-in connection.

[0125] After the shading hood is assembled, the objective lens 610 is sealed and protected by the shading hood, which can avoid interference from strong light and also play a role in dust and water resistance. However, in a non-harsh environment, long-term sealing is not conducive to heat dissipation and will affect the equipment. Frequent removal of the shading hood is time-consuming and laborious.

[0126] Therefore, in non-harsh conditions, one only needs to grasp the grip groove 723 on the docking ring 722 to lift and rotate the inner light shield 72 until the air holes 73 on the inner and outer light shields 71 ​​are aligned to achieve the ventilation effect and avoid overheating of the equipment.

[0127] Before the detection equipment is put into operation, it is necessary to do a good job of leveling. First, open the three supporting legs 802 and support them on the ground through the telescopic plate 805 to support the entire device. Then observe the display of the circular level 604 on the laser emission assembly 6, and adjust the height of the supporting legs 802 one by one to achieve a rough leveling effect. After rough leveling, observe the display of the tube level 611 and turn the foot screw 602 on the laser emission assembly 6 to adjust the position of the upper base plate until the tube level 611 shows that the leveling is completed.

[0128] When controlling the height of the telescopic plate 805, it is necessary to rotate the handle 806, and the handle 806 drives the active bevel gear 807 and the driven bevel gear 808 to rotate, thereby realizing the rotation of the threaded rod 809. At this time, the telescopic plate 805, which is sleeved on the outside of the threaded rod 809 through the ball nut, will move along the direction of the thread to achieve the height adjustment function. In this setting, the position of the handle 806 is located on the upper half of the support foot 802, which is more convenient for the operator to operate alone. While adjusting, the display of the circular level 604 can be observed. At the same time, the threaded rod 809 and the telescopic plate 805 can be self-locking through the thread setting, and there is no need to manually lock it immediately after adjustment.

[0129] After the position of the telescopic plate 805 is adjusted, the position of the telescopic plate 805 is further fixed by passing nuts and bolts through the limit block 810 and the bracket 804;

[0130] Since some communication towers are located in remote areas and the flatness of the ground is not high, the support legs 802 will be difficult to level after supporting due to the uneven ground, so a balancing component 9 is provided. The flat plate 903 in the balancing component 9 will automatically adjust according to the inclination of the ground after contacting the ground through the setting of the movable shaft 901. After the adjustment, tightening the locking nut 902 can limit the rotation of the movable shaft 901. The contact area between the flat plate 903 and the ground is larger than that of the telescopic plate 805, so as to avoid the telescopic plate 805 suddenly sinking with the ground during operation;

[0131] At the same time, a plurality of balancing plates 905 that can be retracted individually by springs 904 are arranged inside the plane plate 903. When the balancing plates 905 are in contact with the ground, they will retract automatically according to the unevenness of the ground, so that the plane plate 903 is always in close contact with the ground, which greatly reduces the difficulty of leveling. The guide plate 906 moves with the balancing plate 905 in the guide groove arranged in the plane plate 903, which improves the stability of the balancing plate 905 and can only move along the direction of the guide groove.

[0132] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
