Description

Technical Field

[0001] The invention belongs to the technical field of communication tower correction, and in particular relates to a communication iron tower with earthquake-resistant function. Background Art

[0002] Communication towers are steel structures used to support communication antennas and signal transmission equipment and are widely used in the communications industry. The design and construction of communication towers need to take into account the transmission requirements of communication signals, the installation and maintenance requirements of antennas, and the height, structure, and materials of the towers.

[0003] During the use of communication towers, they will be affected by wind. The wind applies a unilateral force to the communication towers. The tower body is subjected to unilateral force and the force is transmitted to the tower foundation, causing the foundation of the communication tower to sink unevenly, thereby causing the communication tower to tilt. Ground subsidence will also cause the communication tower to tilt. The tilt of the communication tower can easily lead to stress concentration on the tower body, reduce the service life of the communication tower, and cause a collapse accident. Therefore, it is necessary to correct the tilt of the communication tower.

[0004] In the prior art, for example, Chinese patent application CN113373996A discloses a device for adjusting uneven settlement of iron tower column feet and a method for supporting and lifting, wherein the device includes a plurality of telescopic oil cylinders, which respectively support the column feet of the iron tower, and the telescopic oil cylinders can be extended and retracted, and when the telescopic oil cylinders are extended and retracted, the height of the iron tower can be raised and lowered, thereby adjusting the inclination angle of the iron tower. When the iron tower is tilted, it is necessary to first measure the inclination angle of the iron tower, and then calibrate the iron tower according to the measurement result. However, in the prior art, the iron tower correction and adjustment device cannot measure the inclination angle of the iron tower, and thus additional measurement work is required, which increases the workload of adjusting the inclination angle of the iron tower.

[0047] Refer to the following Figures 1 to 16 A communication tower with earthquake resistance provided by an embodiment of the present invention is described.

[0048] A communication iron tower with earthquake resistance comprises a tower body 100, a base 200, a fixing column 400 and a fixing assembly.

[0049] The base 200 is installed in the ground or other fixed surfaces; specifically, the base 200 can be buried in the ground or buried and fixed in other fixed surfaces, such as a building.

[0050] The column foot of the tower body 100 is installed on the base 200; specifically, the tower body 100 is provided with a plurality of column foots, and the base 200 is provided with a plurality of corresponding column foots.

[0051] The fixing assembly includes an anchor seat 500 , a cable 110 , a first elastic member 530 , a sliding block 540 and a rotating rod 550 .

[0052] The fixed column 400 is fixedly installed in the fixed table at the middle position below the tower body 100; a sliding groove is opened in the radial direction on the fixed column 400, and the sliding groove is arranged horizontally. The sliding block 540 is slidably installed in the sliding groove. The first elastic member 530 can be retracted and rebounded. The first elastic member 530 is arranged in the sliding groove. The first elastic member 530 applies a pulling force to the sliding block 540, so that the sliding block 540 retracts into the sliding groove. The first elastic member 530 is a structure with a retracting and rebounding function, such as a coil spring or a leaf spring.

[0053] The anchor seat 500 is installed on the ground or other fixed table surface, one end of the cable 110 is fixed on the tower body 100, and the other end of the cable 110 is passed through the anchor seat 500 and fixedly connected to the sliding block 540. The cable 110 is slidably installed in the anchor seat 500. When the tower body 100 is tilted, the cable 110 will be pulled to move, and the movement of the cable 110 drives the sliding block 540 to move, so that the sliding block 540 extends out of the sliding groove. At the same time, the first elastic member 530 applies a force to the sliding block 540 to make the sliding block 540 retract into the sliding groove or have a tendency to retract into the sliding groove, thereby promoting the tower body 100 to restore the vertical state.

[0054] A rotating hole is vertically opened along the axial direction on the upper end surface of the fixed column 400, and the rotating hole is connected to the sliding groove. The rotating rod 550 is rotatably installed in the rotating hole. A first gear is fixedly connected to the rotating rod 550, and a first rack 560 is arranged on the sliding block 540. The first gear is meshed with the first rack 560, and the sliding block 540 moves through the first rack 560 and the first gear to drive the rotating rod 550 to rotate; the tower body 100 tilts and drives the cable 110 to move, and the movement of the cable 110 drives the sliding block 540 to extend out of the sliding groove, and the movement of the sliding block 540 drives the first rack 560 to move, and the movement of the first rack 560 drives the first gear to rotate, and the rotation of the first gear drives the rotating rod 550 to rotate. The inclination angle of the tower body 100 can be calculated according to the rotation angle of the rotating rod 550, and then the angle of the tower body 100 can be corrected in a targeted manner.

[0055] In some embodiments, an indicator needle 130 is provided at the upper end of the rotating rod 550. The rotation of the rotating rod 550 drives the indicator needle 130 to rotate. The length of the indicator needle 130 is greater than the diameter of the rotating rod 550. The rotating rod 550 and the indicator needle 130 rotate at the same angle. The needle tip of the indicator needle 130 rotates a greater distance than the outer edge of the rotating rod 550, and then through the magnifying effect of the indicator needle 130, the inclination angle of the tower body 100 is more clearly reflected.

[0056] The fixing assembly includes two anchoring seats 500, and two cables 110 are also provided; the two cables 110 in the same fixing assembly are named as the first cable and the second cable for the convenience of distinction, the first cable runs through one anchoring seat 500, and the second cable runs through the other anchoring seat 500, one end of the first cable is fixed to the tower body 100, and the other end is fixed to the sliding block 540; one end of the second cable is fixed to the tower body 100 together with one end of the first cable, and the other end is fixed to the same sliding block 540 together with the other end of the first cable. Multiple fixing assemblies are provided along the circumference of the tower body 100, and the tilt direction of the tower body 100 can be measured more accurately through the rotation angles of the rotating rods 550 of different fixing assemblies.

[0057] The cable 110 has a support section, which is located between the anchor seat 500 and the sliding block 540. The support section passes under the base 200 and can prevent the base 200 from collapsing downward to a certain extent.

[0058] The base 200 includes a housing 210 , a first telescopic rod 220 , and a damping unit.

[0059] The housing 210 is installed on the ground or other fixed surfaces.

[0060] The first telescopic rod 220 is vertically installed inside the housing 210. Specifically, the first telescopic rod 220 is a hydraulic telescopic rod or an electric push rod, and can also be a structure with a telescopic function such as a lead screw nut telescopic mechanism.

[0061] The damping unit includes a damping cylinder 300 and a piston rod 310 .

[0062] The damping cylinder 300 is disposed above the first telescopic rod 220 , and the first telescopic rod 220 can be telescoped to drive the damping cylinder 300 to move up and down.

[0063] One end of the piston rod 310 is sealed and slidably installed in the damping cylinder 300; a first channel 390 is provided on one end of the piston rod 310 that is sealed and matched with the damping cylinder 300, and this end of the piston rod 310 divides the interior of the damping cylinder 300 into two parts, an upper part and an lower part, and the damping oil in the lower part of the damping cylinder 300 enters the upper part of the damping cylinder 300 through the first channel 390. The horizontal cross-sectional area of ​​the first channel 390 is adjustable, and the horizontal cross-sectional area of ​​the first channel 390 is the aperture of the first channel 390.

[0064] The column foot of the tower body 100 is fixed above the piston rod 310. Specifically, the extension of the first telescopic rod 220 can drive the damping cylinder 300 to move upward, and the upward movement of the damping cylinder 300 can drive the piston rod 310 to move upward. The upward movement of the piston rod 310 can drive the column foot of the tower body 100 to move upward. Similarly, the shortening of the first telescopic rod 220 can drive the column foot of the tower body 100 to move downward, and then the inclination angle and inclination direction of the tower body 100 are changed by the extension and contraction of the first telescopic rod 220.

[0065] Specifically, the column foot of the tower body 100 can exert a downward force on the piston rod 310, and the piston rod 310 exerts a force on the damping oil, and the damping oil flows through the first channel 390, so that the piston rod 310 moves downward relative to the damping cylinder 300. The horizontal cross-sectional area of ​​the first channel 390 is small, and the downward movement speed of the piston rod 310 is much lower than the telescopic speed of the first telescopic rod 220. When the column foot is subjected to uneven force from the tower body 100, the damping oil under the piston rod 310 flows to the top of the piston rod 310, and then slowly releases the force applied to the column foot by the tower body 100, thereby preventing the tower body 100 from being in a state of stress concentration for a long time due to factors such as wind force or bottom surface settlement.

[0066] The stress concentration of the tower body 100 will reduce the service life of the tower body 100 structure, thereby causing unnecessary losses and safety risks. In some embodiments, an oil pump is also connected to the outside of the cylinder wall of the damping cylinder 300, and the oil pump is connected to the upper end of the damping cylinder 300 and the lower end of the damping cylinder 300. The damping oil pumped by the oil pump can transport the damping oil above the piston rod 310 to the bottom of the piston rod 310, or transport the damping oil below the piston rod 310 to the top of the piston rod 310, and then the damping cylinder 300 is retracted and reset by the oil pump.

[0067] The piston rod 310 has a rod body portion 320 and a plug body portion 330 , and the rod body portion 320 is vertically fixed above the plug body portion 330 .

[0068] The plug body 330 is slidably sealed with the inner wall of the damping cylinder 300. Specifically, the diameter of the plug body 330 is greater than the diameter of the rod body 320.

[0069] The first channel 390 is vertically opened in the plug body 330. Specifically, the position of the first channel 390 is staggered with the position of the rod body 320, and the damping oil is located above and below the plug body 330. The column foot of the tower body 100 is set on the rod body 320. In some embodiments, the upper end of the rod body 320 is also fixed with a mounting plate 120, and the column foot of the tower body 100 is connected to the mounting plate 120 by bolts.

[0070] The plug body 330 is further provided with a second channel 395 . The horizontal cross-sectional area of ​​the second channel 395 is larger than that of the first channel 390 . The first channel 390 runs through the second channel 395 .

[0071] The damping unit also includes a blocking plate 340, which is slidably installed in the second channel 395. The blocking plate 340 has a first relative position and a second relative position during the sliding process in the second channel 395. In the first relative position, the blocking plate 340 can block the first channel 390, and the effective flow cross-sectional area of ​​the damping oil in the first channel 390 is zero, and the damping oil above and below the plug body 330 cannot flow to each other; in the second relative position, the first channel 390 is connected, and the closer the blocking plate 340 is to the second relative position, the larger the effective flow cross-sectional area of ​​the first channel 390, and the greater the flow speed of the damping oil above or below the plug body 330. The greater the tilting force applied to the tower body 100, the greater the deformation of the tower body 100, and the greater the rotation amplitude of the rotating rod 550. According to the indication of the rotation angle of the rotating rod 550, the larger the effective flow cross-sectional area of ​​the first channel 390 needs to be adjusted, so that the damping oil under the plug body 330 flows to the bottom of the piston rod 310 faster, thereby being able to unload a greater force applied by the tower body 100 to the column foot, so as to cope with the greater tilting force and greater deformation brought to the tower body 100 by factors such as wind.

[0072] The damping unit also includes a drive shaft 350, which is fixedly connected to the blocking plate 340 and rotatably installed in the plug body 330. The rotation of the drive shaft 350 can drive the blocking plate 340 to rotate, thereby switching the blocking plate 340 to the first relative position or the second relative position.

[0073] In some embodiments, a plurality of first channels 390 are provided, and all first channels 390 are evenly arranged around the circumference of the driving shaft 350. A plurality of second channels 395 are provided corresponding to the first channels 390, and a plurality of blocking plates 340 are provided corresponding to the second channels 395. All blocking plates 340 are fixedly connected to the same driving shaft 350.

[0074] The communication tower with earthquake resistance function also includes an angle recording component for recording the rotation angle of the rotating rod 550; the angle recording component includes a sliding shell 600, a recording block 610, a recording rack 620, a second elastic member 630, a controller and a force sensor 640.

[0075] The sliding shell 600 is fixedly connected to the fixed column 400, and the recording rack 620 is slidably installed on the sliding shell 600 along a first direction. The first direction is tangential to the rotation direction of the rotating rod 550. The rotating rod 550 and the recording rack 620 are transmitted through gear cooperation. The rotation of the rotating rod 550 can drive the recording rack 620 to slide along the first direction. Specifically, the greater the rotation angle of the rotating rod 550, the greater the moving distance of the recording rack 620.

[0076] The recording block 610 is slidably mounted on the sliding housing 600 along a first direction and is located on a moving path of the recording rack 620 . The movement of the recording rack 620 can push the recording block 610 to move.

[0077] The force sensor 640 is fixedly connected to the sliding housing 600. The second elastic member 630 can be extended and rebounded, and the two ends are respectively connected to the force sensor 640 and the recording block 610; the movement of the recording block 610 drives the second elastic member 630 to extend and retract, and the second elastic member 630 applies a force to the force sensor 640 during the extension and retraction process; the force sensor 640 is electrically connected to the controller, and the force sensor 640 converts the force applied by the second elastic member 630 into an electrical signal and transmits it to the controller, and the controller converts the electrical signal into the rotation angle information of the rotating rod 550. The movement of the recording rack 620 drives the movement of the recording block 610, and the movement of the recording block 610 drives the extension of the second elastic member 630. During the extension of the second elastic member 630, the tension applied to the force sensor 640 increases. In some embodiments, the movement of the recording rack 620 drives the movement of the recording block 610, and the movement of the recording block 610 drives the shortening of the second elastic member 630. During the shortening of the second elastic member 630, the force applied to the force sensor 640 increases. In some embodiments, the controller is electrically connected to the first telescopic rod 220, and the controller controls the extension and retraction of the first telescopic rod 220.

[0078] The second elastic member 630 is a structure with telescopic and rebound functions, such as a coil spring or a leaf spring.

[0079] The rotation of the rotating rod 550 indirectly drives the second elastic member 630 to expand and contract, and the second elastic member 630 expands and contracts to change the magnitude of the force applied to the force sensor 640, and then the inclination angle of the tower body 100 is calculated according to the magnitude of the force applied to the force sensor 640.

[0080] The rotation angle registration assembly further includes a one-way ratchet plate 650 .

[0081] The one-way ratchet plate 650 is slidably mounted on the sliding housing 600 along a second direction, where the second direction is perpendicular to the first direction and parallel to the horizontal plane.

[0082] The one-way ratchet plate 650 is provided with one-way teeth; the one-way ratchet plate 650 has a first sliding position and a second sliding position during the sliding process along the second direction; in the first sliding position, the one-way teeth of the one-way ratchet plate 650 cooperate with the recording block 610, and the one-way teeth limit the recording block 610 to slide along the first direction, thereby preventing the second elastic member 630 from rebounding through the one-way teeth; in the second sliding position, the one-way teeth are disengaged from the recording block 610, so that the second elastic member 630 can rebound, thereby resetting the recording block 610. The one-way ratchet plate 650 is provided to reset the recording block 610 within a preset period, thereby recording the maximum tilt swing amplitude of the tower body 100 within the preset period. The preset period is set according to the actual needs of the project.

[0083] The one-way ratchet plate 650 slides in the second direction to switch to the first sliding position or the second sliding position.

[0084] The turning angle recording assembly further includes a second telescopic rod 660 that is slidably arranged along the second direction. The second telescopic rod 660 can be telescoped. The one-way ratchet plate 650 is fixedly connected to the second telescopic rod 660. The telescoped second telescopic rod 660 drives the one-way ratchet plate 650 to move along the second direction, so that the one-way ratchet plate 650 switches to the first sliding position or the second sliding position. Specifically, one end of the second telescopic rod 660 is fixedly connected to the sliding housing 600, and the other end of the second telescopic rod 660 is fixedly connected to the one-way ratchet plate 650. The telescoped second telescopic rod 660 can drive the one-way ratchet plate 650 to move along the second direction. The second telescopic rod 660 is a hydraulic telescopic rod or an electric push rod, and can also be a structure with a telescopic function such as a lead screw nut telescopic mechanism.

[0085] Two second elastic members 630 are provided, and the two second elastic members 630 are provided on both sides of the force sensor 640 along the first direction. Two recording blocks 610 are provided accordingly, and when the one-way ratchet plate 650 is located at the first sliding position, the two recording blocks 610 can cooperate with the one-way ratchet plate 650 through the one-way teeth; when the one-way ratchet plate 650 is switched to the second sliding position, the second elastic member 630 makes the two recording blocks 610 approach each other; the recording rack 620 is located between the two recording blocks 610; the two second elastic members 630 can measure the rotation angle of the rotating rod 550 in two rotation directions.

[0086] The communication tower with earthquake resistance also includes a servo motor, which can drive the drive shaft 350 to rotate. The servo motor is electrically connected to the controller. The greater the rotation angle of the rotating rod 550, the smaller the effective flow cross-sectional area in the first channel 390 is controlled by the controller to rotate the servo motor.

[0087] In some embodiments, the controller is electrically connected to the second telescopic rod 660 , and the controller can control the extension and retraction of the second telescopic rod 660 .

[0088] In some embodiments, the drive shaft 350 is driven manually. Specifically, a second gear 360 is provided at the upper end of the drive shaft 350.

The third gear 370 is rotatably mounted in the rod body 320, and the third gear 370 is meshed with the second gear 360; a meshing gear ring is fixedly connected to the outer edge of the rotating handle 380, and one end of the rotating handle 380 is rotatably mounted in the rod body 320, and the meshing gear ring is meshed with the third gear 370; the pitch circle diameter of the meshing gear ring is smaller than the pitch circle diameter of the third gear 370, and the pitch circle diameter of the third gear 370 is smaller than the pitch circle diameter of the second gear 360, so that the rotation of the drive shaft 350 can be more accurately controlled when the rotating handle 380 is manually driven. The rotating handle 380 is manually driven to rotate, the rotating handle 380 drives the third gear 370 to rotate, the third gear 370 drives the second gear 360 to rotate, the second gear 360 drives the driving shaft 350 to rotate, and the driving shaft 350 drives the blocking plate 340 to move.

[0089] For ease of understanding, the use process of the device of the present invention is described in detail below.

[0090] The tower body 100 is tilted by factors such as wind. The tilt of the tower body 100 drives and pulls the corresponding cable 110 to move. The cable 110 slides in the anchor seat 500 during the movement. The movement of the cable 110 drives the sliding block 540 to slide and extend out of the sliding slot. When the sliding block 540 extends out of the sliding slot, the sliding block 540 pulls the first elastic member 530 to extend. The first elastic member 530 applies a reaction force to the sliding block 540 to promote the reset of the sliding block 540 and the tower body 100. The sliding of the sliding block 540 drives the rotating rod 550 to rotate. The rotation of the rotating rod 550 drives the recording rack 620 to slide along the first direction on the sliding housing 600. The one-way ratchet plate 650 is located at the first sliding position. The recording rack 620 drives the recording block 610 to move on the one-way ratchet plate 650. The one-way teeth on the one-way ratchet plate 650 cause the recording rack 620 to move in one direction, thereby recording the maximum swing amplitude of the tower body 100.

[0091] The movement of the recording block 610 causes the second elastic member 630 to extend, and the extension of the second elastic member 630 applies a force to the force sensor 640. The force sensor 640 converts the force received into an electrical signal and transmits it to the controller. The controller calculates the inclination angle of the tower body 100 according to the algorithm, and controls the rotation of the servo motor. The rotation of the servo motor can drive the driving shaft 350 to rotate, and the rotation of the driving shaft 350 drives the blocking plate 340 to move, so that the blocking plate 340 is close to or away from the second relative position, thereby adjusting the size of the first channel 390. Through the flow of the damping oil in the damping cylinder 300, the plug body 330 and the rod body 320 move downward to drive the damping oil to move upward, thereby promoting the release of stress of the tower body 100 and the column foot, and preventing the stress concentration of the tower body 100. When the tower body 100 is tilted, the greater the inclination of the tower body 100, the greater the force received by the column foot, the greater the force received by the column foot, the larger the effective flow cross-sectional area of ​​the first channel 390 is required, and the greater the flow speed of the damping oil, the faster the column foot can release the received stress.

[0092] The controller is electrically connected to the first telescopic rod 220. The controller adjusts the extension and retraction of the first telescopic rod 220 in a long cycle according to the electrical signal of the force sensor 640, and adjusts the extension and retraction of the second telescopic rod 660 and the rotation of the servo motor in a short cycle. The long cycle is a multiple of the short cycle. For example, the short cycle is three days and the long cycle is thirty days. The controller resets the recording block 610 once through the second telescopic rod 660 and adjusts the effective flow cross-sectional area of ​​the first channel 390 once through the servo motor every three days, and adjusts the length of the first telescopic rod 220 once every ten short cycles.

[0093] The controller adjusts the effective flow cross-sectional area of ​​the first channel 390 according to the maximum distance moved by the recording block 610 in a short period, that is, the maximum inclination angle of the tower body 100. The larger the inclination angle of the tower body 100, the larger the effective flow cross-sectional area of ​​the first channel 390.

[0094] The controller adjusts the tower body 100 through the first telescopic rod 220 according to the parameters after the recording block 610 is reset in the long cycle. When the tower body 100 maintains a certain tilt angle after several short cycles, the tilt of the tower body 100 drives the cable 110 to move, and the movement of the cable 110 indirectly causes the rotating rod 550 to rotate and maintain a certain rotation angle. The rotation of the rotating rod 550 drives the recording rack 620 to move to a certain distance and then stop. The controller shortens the second telescopic rod 660, and the shortening of the second telescopic rod 660 switches the one-way ratchet plate 650 to the second sliding position. The recording block 610 is reset under the action of the second elastic member 630. Due to the blocking effect of the recording rack 620 on the recording block 610, the recording block 610 does not return to the initial position, and then the recording block 610 applies a force to the force sensor 640 through the second elastic member 630. The force sensor 640 converts the force received into an electrical signal and transmits it to the controller. The controller calculates the difference in the magnitude of the force applied to the force sensor 640 by the two second elastic members 630. The controller calculates the inclination angle of the tower body 100 according to the difference and a preset algorithm, and then calculates the sinking amount of each column foot of the tower body 100 according to the inclination angle of the tower body 100, and sorts them according to size. The principle of the shortest adjustment path is adopted to analyze the results of various adjustment sequence combinations of each column foot and select the optimal solution. Then the controller telescopes the corresponding first telescopic rod 220 according to the optimal solution to adjust the height of the corresponding column foot, thereby correcting the tower body 100.

[0095] The tower body 100 is calculated using the shortest path principle. For example, the tower body 100 has four column feet, and the sinking of the four column feet is respectively the first distance, the second distance, the third distance and the fourth distance, and the average value of the four distances is calculated; Implementation plan 1: Calculate the total distance that the four column feet need to move and lift when the four column feet are adjusted to the average value. Implementation plan 2: Take the first column foot as the reference, adjust the remaining column feet to the same height as the first column foot, and calculate the total distance that each column foot needs to move and lift; similarly, take the second column foot, the third column foot and the fourth column foot as the reference, and obtain implementation plans three, four and five. Compare the total distances that the four column feet need to move and lift, and take the minimum total distance that the four column feet need to move and lift as the optimal solution.

It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
