Description

Technical Field

[0001] The present invention relates to the technical field of communication equipment, and in particular to a device for adjusting the verticality and tension of a guyed wire tower or mast. Background Art

[0002] In many medium wave, short wave and long wave transmitting antenna system projects, it is often necessary to adjust and measure the verticality of the guy tower and the tension of the guy rope. In the past, traditional installation operations mainly used hand winches and mechanical tension gauges to complete the adjustment and force measurement work. The use of these equipment and tools has been followed for decades and has accumulated a wealth of experience, becoming a traditional operating method.

[0003] In the adjustment of the verticality and the tension of the guyed wires of a tall guyed tower or mast, different equipment is used to adjust the verticality of the guyed tower and the tension of the guyed wires, respectively. Specifically, in the process of adjusting the verticality of a tall guyed tower or mast with double guyed wires, it is necessary to set up a theodolite at a distance beyond the height of the tower or mast, and use two hydraulic jacks, two groups of operators, surveyors and commanders, and several auxiliary personnel to cooperate with each other to complete the adjustment. In the process of adjusting the tension of the guyed wires of a tall guyed tower or mast with double guyed wires, the double guyed wires of the tower or mast will be connected to a tension gauge through a hand winch and connected to a temporary anchor. Two groups of operators work simultaneously to ensure the tension balance between the two guyed wires.

[0004] The wire rope tension encountered in the actual construction process is very large, often exceeding 150KN, and the wire rope diameter will also exceed 50 mm. Not only does it require a lot of manpower, but the work efficiency is also very low. The main structural components are very heavy and need to be installed with the help of lifting equipment. The hand chain hoist used is heavy but the tension it can provide is very limited. It consumes physical strength and is prone to equipment failure, which poses certain safety hazards. The accuracy of the mechanical tension meter's measurement data is low, and the weight and volume are both large. When adjusting the tension, at least 8 people must work together to complete the adjustment of a set of ropes. The single-direction tension adjustment requires at least one day of work. In actual operation, if the cooperation between the groups of personnel is not good, the force will be unbalanced, and the hand chain hoist will easily get stuck, the chain will jump, and there will be certain safety hazards.

[0042] See also Figure 2 to Figure 4 , a device 100 for adjusting the verticality of a guyed tower and the tension of a guyed rope is disclosed in an embodiment of the first aspect, comprising:

[0043] The installation frame includes an upper tensioning assembly 110, a lower tensioning assembly 120 and two tension rods 130. The turnbuckle 500 is located in a space enclosed by the upper tensioning assembly 110, the lower tensioning assembly 120 and the two tension rods 130. The bottom end of the pull rope 300 passes through the upper tensioning assembly 110 and is connected to the upper lead screw 510 of the turnbuckle 500 through a joint 310. The top end of the pull rod 130 protrudes from the upper tensioning assembly 110 and the upper tensioning assembly 110 can move axially relative to the pull rod 130 along the pull rod 130. Adjustment sleeves 131 are respectively provided on each of the pull rods 130 protruding from the top of the upper tensioning assembly 110. The bottom end of the pull rod 130 protrudes from the lower tensioning assembly 120 and the pull rod 130 is fixedly connected to the lower tensioning assembly 120. The lower tensioning assembly 120 is also fixedly connected to the lower lead screw 520 of the turnbuckle 500.

[0044] The hollow hydraulic jack assembly includes a hydraulic control end 150 and two hollow hydraulic jacks 140 connected thereto. Each hollow hydraulic jack 140 is sleeved on the bottom end of a corresponding pull rod 130. The hollow plunger 144 of each hollow hydraulic jack 140 extends from or retracts into the oil cylinder 141 from the side of the oil cylinder 141 facing the ground foundation 400, and the hollow plunger 144 is fixedly connected to the bottom end of the pull rod 130. The two hollow hydraulic jacks 140 are controlled by the hydraulic control end 150. During the adjustment process, the tension of the pull rope 300 is transmitted by the turnbuckle bolt 500 through the lower tensioning assembly 120, the pull rod 130 and the upper tensioning assembly 110; the oil cylinder 141 of the hollow hydraulic jack 140 has a coaxially arranged inner wall and outer wall, a first space for the pull rod 130 to pass through is formed on the inner side of the inner wall of the oil cylinder 141, and a second space for accommodating a hollow plunger 144 is formed between the inner wall and the outer wall of the oil cylinder 141, and the bottom end of the hollow plunger 144 is provided with a center hole for the pull rod 130 to pass through;

[0045] The force measuring module includes two annular force sensors 161, each of which is respectively mounted on a pull rod 130 located between the top end of the hollow hydraulic jack 140 and the bottom end of the lower tensioning assembly 120, and is used to measure the tension of the pull rope 300 transmitted by the basket bolt 500 through the lower tensioning assembly 120, the pull rod 130 and the upper tensioning assembly 110 during the adjustment process.

[0046] In some embodiments, the mounting frame provides a basis for mounting the remaining components of the adjustment device 100 of this embodiment.

[0047] Specifically, the installation frame is in a tic-tac-toe shape as a whole, and the upper tensioning assembly 110 includes two upper tensioning frame clamps 111 made of steel (the material can be selected as Q355B) arranged opposite to each other. The two upper tensioning frame clamps 111 are fixedly connected by a first bolt 112, and first grooves matching the outer contours of the pull rod 130 and the pull rope 300 are respectively provided on opposite sides of the two upper tensioning frame clamps 111. The surface of the first groove is smooth, that is, the whole formed by the two upper tensioning frame clamps 111 can slide axially along the pull rod 130 after being acted upon by the hollow hydraulic jack 140, and the pull rope 300 can also slide between the two upper tensioning frame clamps 111 after being acted upon by the tension of the basket bolt 500.

[0048] The lower tensioning assembly 120 in the mounting frame includes two lower tensioning frame clamps 121 made of steel (the material can be selected as Q355B) arranged opposite to each other. The two lower tensioning frame clamps 121 are fixedly connected by a second bolt 123. The lower lead screw 520 of the basket bolt 500 is fixedly connected to the two lower tensioning frame clamps 121 through a clamping nut 122 located between the two lower tensioning frame clamps 121. A second groove and two third grooves are respectively provided on opposite sides of the two lower tensioning frame clamps 121. The second groove is a stepped groove to match the outer contour of the clamping nut 122 and the lower lead screw 520. The two third grooves are symmetrically arranged on the left and right sides of the second groove to match the outer contour of a corresponding pull rod 130 respectively.

[0049] Further, see Figure 3 In (a) and (b), the clamping nut 122 is a circular ring nut formed by splicing two semicircular first nut blocks 1221 and second nut blocks 1222. The first nut block 1221 and the second nut block 1222 are respectively provided with matching protrusions 122a and recesses 122b at the splicing position to form a shear key. Pin holes 122c are also respectively provided on both sides of the protrusions 122a and recesses 122b of the first nut block 1221 and the second nut block 1222. The first nut block 1221 and the second nut block 1222 are connected into a whole by a fastening screw matched with the pin holes 122c. The first nut block 1221 and the second nut block 1222 are both provided with an internal thread 122d that matches the external thread of the lower screw 520 of the basket bolt 500. The threaded cooperation further increases the friction between the lower clamping nut 122 and the lower screw 520 of the basket bolt 500, thereby preventing relative slippage between the lower tensioning assembly 120 and the lower screw 520 of the basket bolt 500 during the adjustment process.

[0050] The two tie rods 130 in the installation frame have the same structure. Each tie rod 130 is composed of a plurality of short tie rods of different lengths. An adjusting sleeve 131 is provided on each tie rod 130 protruding from the top of the upper tension frame clamping plate 111. The top of the adjusting sleeve 131 is fixedly connected to the top of the tie rod 130 through a matching first gasket 132 and a first nut 133. A second gasket 134 is provided between the bottom end of the adjusting sleeve 131 and the top of the upper tension frame clamping plate 111. The integral structure formed by the two upper tension frame clamping plates 111 can move axially along the tie rod 130. The portion of each tie rod 130 protruding from the bottom end of the lower tension frame clamping plate 121 is used to install the corresponding hollow hydraulic jack 140 and annular force sensor 161. Each tie rod 130 and the adjusting sleeve 131 need to be selected according to the length of the basket bolt 500 actually used. To meet the needs of different pull rope adjustments, this embodiment is equipped with short pull rods of different specifications such as 2.5 meters, 3 meters, and 4 meters, all with a diameter of 30 mm. Each short pull rod can be combined in multiple ways to form a pull rod of suitable length and used in pairs as needed.

[0051] In some embodiments, see Figure 2 , Figure 4, two hollow hydraulic jacks 140 in the hydraulic jack assembly are invertedly installed at the bottom end of a corresponding tie rod 130. Each hollow hydraulic jack 140 includes a cylinder 141 and a hollow plunger 144 that can be extended or retracted into the cylinder 141. The cylinder 141 has an inner wall and an outer wall arranged coaxially. A first space for the tie rod 130 to pass through is formed on the inner side of the inner wall of the cylinder 141. A second space for accommodating the hollow plunger 144 is formed between the inner wall and the outer wall of the cylinder 141. The bottom end of the hollow plunger 144 (when the hollow plunger 144 is at the minimum stroke, that is, when the hydraulic jack is not working, the bottom end of the hollow plunger 144 protrudes from the end of the cylinder 141 away from the lower tensioning group 120) is provided with a center hole for the tie rod 130 to pass through, and the bottom end of the hollow plunger 144 is fixed to the bottom end of the tie rod 130 by a matching third gasket 136 and a second nut 135. An oil inlet 141a and an oil outlet 141b are respectively provided on the outer wall of the oil cylinder 141. Each oil inlet 141a is connected to the hydraulic control end 150 via an oil inlet pipeline 142a provided with a first three-way valve 143a, and each oil outlet 141b is connected to the hydraulic control end 150 via an oil outlet pipeline 142b provided with a second three-way valve 143b. The operator C performs pressurization and pressure relief operations on the hollow hydraulic jack 140 through the hydraulic control end 150, and uses the first three-way valve 143a and the second three-way valve 143b to divide the oil inlet and the oil outlet of the hydraulic control end 150 into two. When the hydraulic control end 150 is pressurized, the hollow plunger 144 will gradually extend from the bottom end of the cylinder 141, so that the hollow hydraulic jack 140 bears the corresponding tension of the rope 300 transmitted by the basket bolt 500 through the lower tensioning assembly 120, the pull rod 130 and the upper tensioning assembly 110 during the adjustment process, until the rope tension borne by the basket bolt 500 is completely transferred to the adjustment device 100; when the hydraulic control end 150 is depressurized, the hollow plunger 144 will gradually retract into the cylinder 141, so that the rope tension 300 borne by the hollow hydraulic jack 140 is gradually transmitted to the basket bolt 500 through the lower tensioning assembly 120, the pull rod 130 and the upper tensioning assembly 110, until the rope tension 300 borne by the adjustment device 100 is completely transferred to the basket bolt 500. In a specific embodiment of the present application, the tonnage of the hollow hydraulic jack 140 is 40 tons and the stroke is 257 mm. The outer diameter of the hollow plunger 144 is 70 mm and the diameter of the center hole is 33.3 mm. The power of the electric oil pump in the hydraulic control end 150 is 0.75 kilowatts and is powered by 220V.

[0052] In some embodiments, a fourth gasket 161a and a fifth gasket 161b are respectively provided between the top of the force sensor 161 of the force measuring module and the bottom of the lower tensioning frame clamping plate 121 and between the bottom of the force sensor 161 and the top of the oil cylinder 141 of the hollow hydraulic jack 140, so that when the hollow hydraulic jack 140 is working, the force can be evenly transmitted to the lower tensioning assembly 120 through the force sensor 161, and the data collection of the force sensor 161 is accurate. Further, the force measuring module also includes two sensor headers 162, each of which is connected to a corresponding force sensor 161 through a data line 163, and is used to display the pressure signal collected by the force sensor 161 in real time. Before the test, the display units of the two sensor headers 162 are set to tons, and the values ​​displayed by the two sensor headers 162 are added together, which is the total tension value on the pull rope 300 in the current state. When selecting the force sensor 161 and the sensor header 162, it is necessary to consider that the center hole of the force sensor 161 is suitable for the size of the pull rod 130, the range of the sensor header 162 is suitable for the required tonnage, and the data line 163 is long enough to suit the maximum distance of the operator.

[0053] The principle of the regulating device 100 provided in the embodiment of the present disclosure is:

[0054] The force exerted by two hollow hydraulic jacks 140 on the lower tensioning assembly 120 fixed on the lower lead screw 520 of the turnbuckle bolt 500 drives the two pull rods 130 to move downward along the axial direction of the pull rod 130, generating a downward force on the upper tensioning assembly 110, pulling the pull rope 300 downward, thereby gradually transferring the pull rope tension on the turnbuckle bolt 500 to the adjustment device 100 until all of it is transferred. When the turnbuckle bolt 500 is unloaded, the first positioning nut 521a and the second positioning nut 521b on the lower lead screw 520 of the turnbuckle bolt 500 are adjusted by manpower to change the position of the turnbuckle adjustment frame 530 on the lower lead screw 520. When the adjustment amount of the lower lead screw 520 is insufficient, the adjustment nut on the upper lead screw 510 needs to be adjusted synchronously, so as to change the length of the turnbuckle bolt 500 and then change the tightness of the pull rope 300, thereby adjusting the verticality of the guyed tower 200. At the same time, the pull rope tension value is corrected according to the signal of the force sensor to ensure that the tower body and the antenna system are subjected to balanced and stable forces.

[0055] The steps for installing the adjustment device 100 of the disclosed embodiment are as follows:

[0056] 1. Installation of the upper tensioning assembly 110, the pull rope 300 and the pull rod 130: Clamp the two upper tensioning frame clamps 111 at the joint 310 at the bottom end of the pull rope 300, insert the first bolt 112 into the bolt holes reserved in the two upper tensioning frame clamps 111 and install the matching nuts to complete the combined installation of the upper tensioning assembly 110. Note that the nuts matching the first bolts 112 should not be tightened at this time; according to the length of the basket bolts 500 actually used, the two combined pull rods 130 of appropriate length are respectively passed through the mounting holes on both sides of the upper tensioning frame clamps 111, and the appropriate number of adjusting sleeves 131 are selected according to the length of the pull rods 130. According to the first gasket, The sheet 132, the adjusting sleeve 131, the second gasket 134 and the first nut 133 are inserted into the top of the pull rod 130 in this order and the first nut 133 is tightened. The thread of the pull rod 130 should exceed the first nut 133 by at least 3 cm to complete the assembly of the top of the pull rod 130 and the upper tensioning frame clamping plate 111; after adjusting the assembled upper tensioning assembly 110 to a suitable position (the present embodiment has no special requirements for the installation angle of the upper tensioning assembly 110, and an angle that is convenient for technicians to operate can be used), tighten the nut matched with the first bolt 112 to complete the installation and fixation of the upper tensioning assembly 110, the pull rope 300 and the pull rod 130;

[0057] 2. Installation of the lower tensioning assembly 120: According to the diameter of the lower lead screw 520 of the turnbuckle bolt 500, select a suitable detachable clamping nut 122, clamp the first nut block 1221 and the second nut block 1222 of the clamping nut 122 on the lower lead screw 520, fix the first nut block 1221 and the second nut block 1222 with the fastening screw, and then screw the clamping nut 122 to a working position sufficient for installing accessories such as the force sensor 161 and the hollow hydraulic jack (the installation position should ensure that the length of the pull rod 130 after passing through the lower tensioning assembly 120 is sufficient to install the force sensor 161, the hollow hydraulic jack, etc. The two lower tension frame clamps 121 are clamped on the clamping nut 122 and the two tie rods 130, and the second bolt 123 is inserted into the bolt holes reserved in the two lower tension frame clamps 121 and the matching nuts are installed. The angle of the lower tension frame clamp 121 is adjusted so that the lower tension frame clamp 121 and the upper tension frame clamp 111 are located in the same plane, and the nut matched with the second bolt 123 is tightened to complete the installation of the lower tensioning assembly 120 on the lower lead screw 520 of the basket bolt 500;

[0058] 3. Installation of the force sensor 161 and the hollow hydraulic jack 140 on one side: insert them into the bottom end of the tie rod 130 in the order of the fourth gasket 161a - force sensor 161 - fifth gasket 161b - hollow hydraulic jack 140 - third gasket 136 - second nut 135, tighten the second nut 135, and require that the thread at the bottom end of the tie rod 130 should exceed the second nut by more than 3 cm to ensure the tensile strength of the tie rod 130;

[0059] 4. The installation of the force sensor 161 and the hollow hydraulic jack 140 on the other side is the same as step 3;

[0060] 5. Hydraulic oil circuit connection: connect the oil inlet 141a of the two hollow hydraulic jacks 140 to the two interfaces on one side of the two ends of the first three-way valve 143a respectively, and connect the single port on the other side of the first three-way valve 143a to the interface of the hydraulic control end 150; connect the oil outlet 141b of the two hollow hydraulic jacks 140 to the two interfaces on one side of the two ends of the second three-way valve 143b respectively, and connect the single port on the other side of the second three-way valve 143b to the interface of the hydraulic control end 150;

[0061] 6. Connection of force sensors: Connect two force sensors 161 to their respective sensor headers 162 via data cables 163;

[0062] 7. Connect the hydraulic control terminal 150 to a 220V power supply and test the working status of the adjusting device 100. If any problems are found, they should be corrected in time. The installation of the entire adjusting device 100 is now completed.

[0063] The method for adjusting the verticality of the guying tower and the tension of the guying rope using the above-mentioned adjustment device 100 provided in the embodiment of the present disclosure includes the following steps:

[0064] S1. Preparation and installation of adjustment devices

[0065] S11. Lift the antenna suspended on the top of the tower to a specified working height through a winch and a transmission mechanism;

[0066] S12. Select two adjacent directions in the southeast, northwest and northeast of the guying tower, set up the theodolite or total station at a distance greater than the tower height H, and use the theodolite or total station to measure the verticality of the tower. If the verticality of the tower does not meet the standard, the surveyor (the surveyor is not shown in the figure) determines the side of the pull rope (hereinafter referred to as "the pull rope to be adjusted") 300 that needs to be adjusted, and installs the adjustment device 100 between the pull rope to be adjusted 300 and the basket bolt 500. The installation steps are as mentioned above and will not be repeated here.

[0067] S2. Verticality correction and tension test

[0068] S21. Preliminarily determine the adjustment amount of the turnbuckle bolt 500 (e.g. shorten by 30 cm) according to the tower body offset value given by the surveyor, and screw the second positioning nut 521b on the lower lead screw 520 on the turnbuckle bolt 500 30 cm toward the side close to the lower tensioning assembly 120 in advance;

[0069] S22. According to the adjustment amount of the turnbuckle bolt 500 determined in step S21, the on-site commander B issues a command to the operator C of the hydraulic control end 150 to start the hydraulic control end 150 to gradually transfer the tension of the to-be-adjusted pull rope 300 borne by the turnbuckle bolt 500 to the adjustment device 100 until all of it is transferred. At the same time, the surveyor is asked to observe the verticality of the tower body, so that the deviation of the verticality of the tower body is ≤H / 1500. For a guyed tower with a design height of ≥200 meters, the overall verticality deviation is ≤H / 500. The sum of the tension values ​​of the two sensor heads 162 is simultaneously observed, which should be within the range of ±10% of the design tension value of the to-be-adjusted pull rope 300. If the sum of the tension values ​​of the two sensor heads 162 exceeds the index value, it is necessary to return to review the tension of the remaining side pull ropes connected to the guyed tower 200 until the tension of the to-be-adjusted pull rope 300 is qualified.

[0070] S23. According to the adjustment amount of the turnbuckle bolt 500 determined in step S21, the on-site commander B arranges personnel to screw the turnbuckle adjustment frame 530 of the turnbuckle bolt 500 toward the side close to the lower tensioning assembly 120 by 30 cm. If the adjustment amount of the lower lead screw 520 is insufficient, the first adjustment nut 511a and the second adjustment nut 511b on the upper lead screw 510 are screwed toward the side close to the joint 310 synchronously to ensure that the sum of the screwing length of the turnbuckle adjustment frame 530 on the lower lead screw 520 and the adjustment amount of the first adjustment nut 511a and the second adjustment nut 511b on the upper lead screw 510 screwed toward the side close to the joint 310 is 30 cm; screw the first positioning nut 521a until it contacts the turnbuckle bolt frame 530;

[0071] S24, when the basket adjustment frame 530, the first adjustment nut 511a and the second adjustment nut 511b reach the specified position, the on-site commander B notifies the operator C of the hydraulic control end 150 to perform the pressure relief operation, and arranges the surveyor to observe the verticality of the tower body. When the operator C of the hydraulic control end completes the pressure relief instruction, the adjustment device 100 has transferred all the tension to the basket bolt 500. At this time, the re-measured tower body verticality should meet the index requirements;

[0072] S3. Verification after adjustment

[0073] When the to-be-adjusted rope 300 is adjusted, the tension values ​​of the ropes on the other two sides will change in tandem. If the tension value requirement is not met, the process returns to step S2 and is adjusted again until the verticality of the rope tower 200 and the tension values ​​of the ropes 300 on each side meet the design requirements.

[0074] S4. End of work

[0075] S41, tightening the adjusting nuts and the positioning nuts on the turnbuckle bolt 500;

[0076] S42, dismantling the adjusting device 100, in the reverse order of the installation steps;

[0077] S43. Complete the cleanup of the construction site.
