Description

Technical Field

[0001] The present invention relates to the technical field of electric tension machines, and specifically to an electric tension machine and its usage method. Background Art

[0002] An electric tension machine is a professional device that uses electric power to drive and applies a constant tension to cables, optical cables, conductors, etc. through a mechanical transmission system, and is widely used in fields such as power line erection, communication optical cable laying, and high-speed rail catenary construction. Its core function is to ensure that the conductor maintains an appropriate tension during the processes of spreading, traction, and erection, and to avoid sagging due to insufficient tension or conductor damage caused by excessive tension.

[0003] Referring to a new type of electric tension machine disclosed in the patent application with the publication number CN221565330U, by using an electric motor to replace the diesel engine to drive the driving wheel of the tension machine, the problems of high noise, high energy consumption, and exhaust gas emission of the diesel engine are solved, and the speed control of the motor is more accurate than that of the diesel engine, which is convenient to adjust the wire laying speed at any time. During the pulling and wire laying process, the mechanical energy of the motor is recovered and then output to the outside for other electrical equipment to work or stored in a battery. When recovering the energy of the tension machine, it is also a process of the tension machine providing tension, thus solving the problem that the traditional tension machine needs a hydraulic cylinder for heat dissipation.

[0004] The above-mentioned electric tension machine in the prior art has the following defects in actual use: The groove size on the surface of the tension roller of the electric tension machine is a fixed value, and it can only guide cables of a specific size through the device. When the outer diameter of the cable is larger than the groove size, the friction between the cable and the groove increases, and the cable is easily squeezed by the inner wall of the groove and deformed. Even the outer skin of the cable will be cut by the edge of the groove, damaging the internal conductor and causing the insulation layer to be damaged and resulting in electric leakage. When the groove size is larger than the outer diameter of the cable, the cable will swing left and right in the groove, and the abrasion of the outer skin of the cable will be accelerated during the collision between the cable and the inner wall of the groove, reducing the insulation performance.

[0005] Therefore, the present invention proposes an electric tension machine and its usage method to solve the above problems. Summary of the Invention

[0006] Aiming at the deficiencies of the prior art, the present invention provides an electric tension machine and its use method, which solve the problems that the groove size on the surface of the tension roller of the current electric tension machine is a fixed value, and only cables of specific sizes can be guided through the device. When the outer diameter of the cable is larger than the groove size, the friction between the cable and the groove increases, and the cable is easily deformed due to the extrusion of the inner wall of the groove. Even the outer skin of the cable will be cut by the edge of the groove, damaging the internal conductor, resulting in the breakage of the insulating layer and leakage. When the groove size is larger than the outer diameter of the cable, the cable will swing left and right in the groove, and the wear of the outer skin of the cable will be accelerated during the collision between the cable and the inner wall of the groove, reducing the insulation performance.

[0007] To achieve the above objectives, the present invention is realized through the following technical solutions: an electric tension machine and its use method, including a frame, and further including: A first tension wheel mechanism and a second tension wheel mechanism, which are respectively rotatably arranged on the same side of the outer wall of the frame.

[0010] Further, the pressure-bearing unit includes a first lifting rod sealingly and slidably arranged inside the support tube.

The bottom end of the first lifting rod is fixedly provided with a second lifting rod. The bottom end of the second lifting rod slidably penetrates through the partition and is fixedly provided with a limiting baffle.

Moreover, a wireless transmission module for receiving the data of the waterproof pressure sensor and transmitting the data to the terminal device is slidably sleeved on the outer wall of the support tube. Except for the different shapes of the lifting plates, the other structures between the third profiling lifting unit and the first profiling lifting unit are the same.

[0011] Further, the profiling regulation assembly includes a driving roller arranged inside the tension wheel and annular sliding seats fixedly arranged at both ends of the driving roller.

An activity gap is formed between the outer wall of the driving roller and the inner wall of the tension wheel. Multiple jacking units corresponding to the profiling lifting assembly one by one are uniformly fixedly arranged on the outer wall of the driving roller and inside the activity gap. Moreover, a circular groove is formed on the side wall of the driving roller, and a toothed ring is fixedly arranged inside the circular groove.

[0012] Further, the jacking unit includes a mounting plate detachably connected to the outer wall of the driving roller. A first wedge-shaped driving block, a second wedge-shaped driving block, and a third wedge-shaped driving block are respectively fixedly arranged at the top of the mounting plate.

[0013] Further, the power input assembly includes a transmission shaft rotatably penetrating through the side plate. Gears and a crank are respectively fixedly arranged at both ends of the transmission shaft. Moreover, a marking ring is fixedly sleeved on the outer wall of the transmission shaft and outside the tension wheel.

[0014] Further, the position of the marking ring and the side plate is locked by fastening threads. A pointer is also fixedly arranged on the outer wall of the marking ring. Marking wire grooves for marking the position of the pointer are uniformly formed on the outer wall of the side plate around the transmission shaft.

[0015] Furthermore, the electric tension machine also includes a guide wheel rotatably arranged above the No. 1 tension wheel mechanism through an installation bracket for guiding the cable, and a rubber protective sleeve is fixedly sleeved on the outer wall of the guide wheel for protecting the cable.

[0016] The present invention also discloses a method for using an electric tension machine, which is used for the electric tension machine. The method specifically comprises the following steps: Step 1: First, one end of the construction cable is pulled out from the cable drum and wound in turn in the contoured lifting components on the outer walls of the No. 1 tension wheel mechanism and the No. 2 tension wheel mechanism, and finally pulled out through the guide wheel; Step 2: When the driving mechanism drives the No. 1 tension wheel mechanism and the No. 2 tension wheel mechanism to rotate, the cables slide along the surfaces of the multiple contour-bearing lifting components, and the contour-bearing lifting components provide contour-bearing support for the cables during their movement; Step 3. When constructing cables of different sizes, use the power input component to drive the contour control component to rotate the preset angle according to the preset contour, so that the shape of the lifting grooves formed on the top of the multiple contour lifting components is compatible with the size of the cable outer wall, and then wind the cable in the same way as step 1.

[0017] The present invention provides an electric tension machine and a method for using the same. Compared with the prior art, the present invention has the following beneficial effects: 1. An electric tension machine and a method for using the same. A No. 1 tension wheel mechanism and a No. 2 tension wheel mechanism are provided, and a plurality of contour-like lifting assemblies inside the two can simulate contouring according to cables of different sizes, so that the tops of the No. 1 contour-like lifting unit, the No. 2 contour-like lifting unit and the No. 3 contour-like lifting unit in each contour-like lifting assembly can jointly form a non-closed arc-shaped contour that matches the shape of the outer wall of the construction cable, and can ensure that the outer wall of the cable and the tops of the No. 1 contour-like lifting unit, the No. 2 contour-like lifting unit and the No. 3 contour-like lifting unit are tightly fitted, thereby preventing the cable from shaking during movement, and also ensuring that the top of the contour-like lifting assembly has sufficient space for the cable to pass, thereby avoiding the cable being cut by the edge of the non-closed arc-shaped contour during movement, and ensuring the integrity of the cable insulation layer.

[0018] 2. An electric tension machine and its use method, which can quickly adjust according to the external dimensions of the construction cables by setting up multiple contour lifting components. Compared with the traditional method of disassembling the cable duct according to cables of different sizes and performing targeted replacement, the contour adjustment process of the contour lifting component is faster and more efficient, and does not require tedious disassembly and assembly processes, thereby saving time for replacing the cable duct and greatly improving the construction progress of the cable.

[0019] 3. An electric tensioner and its usage method. The cable tension can push the first lifting rod to move through the tops of the first profiling lifting unit, the second profiling lifting unit, and the third profiling lifting unit, and judge the magnitude of the pressure value on the profiling lifting components at different positions according to the amount of red lubricating oil in the tempered glass tube, that is, it can feedback the magnitude of the cable tension. Thus, when there is a large difference in the pressure values among the profiling lifting components at different positions, it can stop the machine for inspection in time to avoid the situation of damage due to excessive cable tension in a local area. Moreover, the waterproof pressure sensor can also capture multiple groups of impact force values relative to itself during the pressured flow of the red lubricating oil, and further feedback the magnitude of the tension of the cable received by each profiling lifting component by calculating the average value of multiple groups of impact force values. Thereby, it can be mutually corroborated with the tension value feedback by the red lubricating oil in the tempered glass tube at the corresponding position, and further accurately feedback the tension value borne by each profiling lifting component to avoid misjudgment.

Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] The present invention provides two technical solutions: an electric tensioner, specifically including the following embodiments: As Figures 1 - 5 , Figures 7 - 9 , Figure 14 Figure 1 shows the first embodiment: an electric tensioner, including a frame 1, and further including: A first tension wheel mechanism 2 and a second tension wheel mechanism 3, which are respectively rotatably arranged on the same side of the outer wall of the frame 1. The first tension wheel mechanism 2 and the second tension wheel mechanism 3 can perform simulation profiling according to the sizes of different construction cables to complete the profiling support for the cables; The first tension wheel mechanism 2 includes a tension wheel 6 and side plates 7 detachably arranged at both ends of the tension wheel 6. A plurality of isolation rings 8 are uniformly and fixedly sleeved on the outer wall of the tension wheel 6. An annular channel for guiding the cable to pass through is formed between two adjacent isolation rings 8. A plurality of installation through grooves 9 are uniformly opened on the outer wall of the tension wheel 6 and located in the annular channel. A profiling lifting component 10 for performing simulation profiling and lifting on the outer wall of the cable is arranged inside each installation through groove 9; A profiling control component 11 is arranged inside the tension wheel 6 and can rotate relative to the tension wheel 6, and is used to synchronously drive a plurality of profiling lifting components 10 to perform profiling operations to ensure that each profiling lifting component 10 has a lifting shape adapted to the construction cable. The profiling control component 11 rotates through the power input by the power input component 12; A driving mechanism 5 is arranged on the side wall of the frame 1 and is used to provide power for the operation of the first tension wheel mechanism 2 and the second tension wheel mechanism 3.

[0025] The electric tensioner further includes a guide wheel 4 rotatably arranged above the first tension wheel mechanism 2 through a mounting bracket for guiding the cable. A rubber protective sleeve for protecting the cable is fixedly sleeved on the outer wall of the guide wheel 4.

[0026] The driving mechanism 5 includes a hydraulic system, an electrical control system, and a safety and auxiliary system. The hydraulic pump in the hydraulic system provides hydraulic power to drive the operation and braking of the tension wheel, and the pressure can be adjusted as needed to control the tension of the cable; the hydraulic motor in the hydraulic system converts hydraulic energy into mechanical energy to drive the rotation of the tension wheel, and the rotation speed and torque of the tension wheel are controlled by adjusting the hydraulic flow; the hydraulic valve group in the hydraulic system includes a pressure regulating valve and a flow valve, which are used to precisely control the pressure and flow of the hydraulic system to ensure that the cable tension remains stable under different working conditions. When the cable tension exceeds the set value, the safety and auxiliary system automatically cuts off the power or alarms to prevent equipment damage. The electrical control system is used to control the normal operation of the hydraulic system; As Figure 6 , Figures 10 - 13 , Figures 15 - 19The second implementation manner is shown. The profiling lifting assembly 10 includes a base 101 detachably arranged in the installation through groove 9 by bolts. Vertically installed through holes 103 and two inclined installed through holes 102 are respectively formed inside the base 101. The two inclined installed through holes 102 are symmetrically arranged on both sides of the vertically installed through hole 103. A first profiling lifting unit 104 and a second profiling lifting unit 105 are respectively arranged inside the two inclined installed through holes 102. A third profiling lifting unit 106 is arranged inside the vertically installed through hole 103. A long groove is further formed on one side of the top of the base 101. A tempered glass tube 107 is fixedly arranged in the long groove. And a scale wire groove 108 is further arranged on the top of the base 101 and on one side of the tempered glass tube 107. An anti-sticking layer is also coated on the inner wall of the tempered glass tube 107, and the red lubricating oil liquid will not adhere to the inner wall of the tempered glass tube 107.

[0027] In this embodiment, the first profiling lifting unit 104 and the second profiling lifting unit 105 have the same structure. The first profiling lifting unit 104 includes a support tube 1041 fixedly arranged in one of the inclined installed through holes 102. A partition 1042 is fixedly arranged inside the support tube 1041. A plurality of through holes are formed on the surface of the partition 1042. And a waterproof pressure sensor 1043 is further fixedly arranged at the bottom of the inner cavity of the support tube 1041. A pressure-bearing unit is arranged inside the support tube 1041 and above the partition 1042.

[0028] In this embodiment, the pressure-bearing unit includes a first lifting rod 1044 that is hermetically and slidably arranged inside the support tube 1041. The top end of the first lifting rod 1044 slidably penetrates through the support tube 1041 and is fixedly provided with a lifting plate 1045. The bottom end of the first lifting rod 1044 is fixedly provided with a second lifting rod 1046. The bottom end of the second lifting rod 1046 slidably penetrates through the partition plate 1042 and is fixedly provided with a limit baffle. A return spring 1047 is slidably sleeved on the outer wall of the second lifting rod 1046 and located between the first lifting rod 1044 and the partition plate 1042. A liquid discharge port 1048 communicating with its inner cavity is further opened on the outer wall of the support tube 1041. A wireless transmission module 1049 for receiving the data of the waterproof pressure sensor 1043 and transmitting the data to the terminal device is also slidably sleeved on the outer wall of the support tube 1041. Except for the different shapes of the lifting plates 1045, the other structures of the third profiling lifting unit 106 and the first profiling lifting unit 104 are the same. The liquid discharge ports 1048 in the first profiling lifting unit 104, the second profiling lifting unit 105, and the third profiling lifting unit 106 are all connected to the tempered glass tube 107 through pipelines. The top plate of the third profiling lifting unit 106 is horizontal. The space inside the support tube 1041 and located between the first lifting rod 1044 and the waterproof pressure sensor 1043 is filled with red lubricating oil. The wireless transmission module 1049 is fixedly arranged at the bottom of the base 101 by bolts; In this embodiment, the profiling control assembly 11 includes a driving roller 111 arranged inside the tension wheel 6 and annular sliding seats fixedly arranged at both ends of the driving roller 111. The two annular sliding seats are rotatably arranged on the inner wall of the tension wheel 6. An activity gap is formed between the outer wall of the driving roller 111 and the inner wall of the tension wheel 6. A plurality of jacking units 113 corresponding to the profiling lifting assemblies 10 one by one are uniformly and fixedly arranged on the outer wall of the driving roller 111 and located inside the activity gap. A circular groove is opened on the side wall of the driving roller 111, and a toothed ring 112 is fixedly arranged in the circular groove. A gear 121 is rotatably arranged in the circular groove, and the gear 121 is meshed with the toothed ring 112. The jacking unit 113 includes a mounting plate detachably connected to the outer wall of the driving roller 111. The top of the mounting plate is fixedly provided with a first wedge driving block a1, a second wedge driving block a2, and a third wedge driving block a3 respectively. The first wedge driving block a1 and the second wedge driving block a2 are symmetrically arranged on both sides of the third wedge driving block a3. The first profiling lifting unit 104, the second profiling lifting unit 105, and the third profiling lifting unit 106 are respectively slidably arranged on the top slope surfaces of the first wedge driving block a1, the second wedge driving block a2, and the third wedge driving block a3.

[0029] In this embodiment, the power input component 12 includes a transmission shaft that rotatably penetrates through the side plate 7. Gears 121 and cranks 122 are respectively fixedly arranged at both ends of the transmission shaft. A marking ring 123 is fixedly sleeved on the outer wall of the transmission shaft and located outside the tension pulley 6. The position between the marking ring 123 and the side plate 7 is locked by fastening threads. A pointer 124 is also fixedly arranged on the outer wall of the marking ring 123. Marking wire grooves for marking the position of the pointer 124 are evenly formed on the outer wall of the side plate 7 around the transmission shaft. When the drive shaft is rotated clockwise, the bottoms of the first profiling lifting unit 104, the second profiling lifting unit 105, and the third profiling lifting unit 106 will respectively climb along the top slope surfaces of the first wedge-shaped drive block a1, the second wedge-shaped drive block a2, and the third wedge-shaped drive block a3. Thus, the tops of the first profiling lifting unit 104, the second profiling lifting unit 105, and the third profiling lifting unit 106 are synchronously gathered together, and the radius of the formed lifting groove decreases. The initial positions of the bottoms of the first profiling lifting unit 104, the second profiling lifting unit 105, and the third profiling lifting unit 106 are located on the lower sides of the top slope surfaces of the corresponding first wedge-shaped drive block a1, the second wedge-shaped drive block a2, and the third wedge-shaped drive block a3. The transmission shaft can only rotate within a certain angle range under the indication of the pointer 124; The present invention also provides a method for using an electric tensioner, which is used for the electric tensioner. The method specifically includes the following steps: Step 1: First, pull out one end of the construction cable from the cable reel and wind it successively in the profiling lifting assemblies 10 on the outer walls of the first tension pulley mechanism 2 and the second tension pulley mechanism 3, and finally pull it out through the guide pulley 4; The specific process is as follows: The tops of the first profiling lifting unit 104, the second profiling lifting unit 105, and the third profiling lifting unit 106 in each profiling lifting component 10 jointly form an unclosed groove. The cable passes through the unclosed groove formed by the tops of multiple profiling lifting components 10 in sequence. When the first tension wheel mechanism 2 and the second tension wheel mechanism 3 are rotating and operating normally, the cable exerts a squeezing force on the lifting plates 1045 of the first profiling lifting unit 104 and the second profiling lifting unit 105 and the top plate of the third profiling lifting unit 106. The pressure pushes the first lifting rod 1044 to slide a certain distance along the inner wall of the support tube 1041, and the return spring 1047 undergoes a certain degree of elastic deformation. Part of the red lubricating oil in the inner cavity of the support tube 1041 is pushed by the first lifting rod 1044 to enter the tempered glass tube 107 through the liquid discharge port 1048. When a greater pressure is applied to the top of the first lifting rod 1044, the more red lubricating oil in the support tube 1041 is pushed by the first lifting rod 1044 into the red lubricating oil in the tempered glass tube 107. By referring to the scale wire groove 108 to measure the filling length of the red lubricating oil in the tempered glass tube 107, it can be observed whether the cable pressures borne by the profiling lifting components 10 at different positions are consistent. If there are significant differences in the values, it is necessary to stop the machine to adjust the cable tension at different positions; Secondly, the waterproof pressure sensor 1043 can detect the impact force of the red lubricating oil on its top after being pressurized. By calculating the average value of the pressure values during the period from the pressure data detected at the top of the waterproof pressure sensor 1043 to the time when the pressure data tends to be stable, the cable tension magnitudes borne by multiple profiling lifting components 10 can be obtained. By comparing the tension values in multiple profiling lifting components 10, it can be judged whether the cable tensions at multiple positions are consistent; When it is necessary to simulate and profile the lifting size according to cables of different sizes, place a section of construction cable sample in one of the profiling lifting units 10, and rotate the crank 122 clockwise with reference to the marked wire groove on the outer wall of the side plate 7. The crank 122 drives the gear 121 to rotate through the transmission shaft. The toothed ring 112 rotates under the drive of the gear 121. When the driving roller 111 rotates, it synchronously drives the lifting units 113 at multiple positions to move. The bottoms of the first profiling lifting unit 104, the second profiling lifting unit 105, and the third profiling lifting unit 106 climb from the lowest end to a higher position along the inclined planes of the first wedge driving block a1, the second wedge driving block a2, and the third wedge driving block a3 respectively. The top lifting plates 1045 of the first profiling lifting unit 104 and the second profiling lifting unit 105 gradually approach the third profiling lifting unit 106, while the top of the third profiling lifting unit 106 gradually moves upward at the same time. The inner diameter of the non-closed annular groove jointly formed by the tops of the first profiling lifting unit 104, the second profiling lifting unit 105, and the third profiling lifting unit 106 gradually decreases, so as to be able to adapt to the cable lifting work with a smaller outer diameter size. The adjustment ends until the outer wall of the construction cable sample is in close contact with the inner walls of the tops of the first profiling lifting unit 104, the second profiling lifting unit 105, and the third profiling lifting unit 106 in the profiling lifting unit 10. After the adjustment is completed, lock the marking ring 123 and the side plate 7 with bolts. It should be noted here that after the profiling lifting assembly 10 completes the simulation and profiling of the cable outer wall, when the first tension wheel mechanism 2 and the second tension wheel mechanism 3 operate, the distance that the first lifting rod 1044 moves due to the cable tension is relatively small, and the first lifting rods 1044 at multiple positions can move synchronously, which will not affect the profiling and lifting of the cable; Step 2: When the driving mechanism 5 drives the first tension wheel mechanism 2 and the second tension wheel mechanism 3 to rotate, the cable slides along the surfaces of multiple profiling lifting assemblies 10, and the profiling lifting assemblies 10 perform profiling support during the movement of the cable; Step 3: When constructing cables of different sizes, use the power input assembly 12 to drive the profiling control assembly 11 to rotate a preset angle according to the preset profile, so that the shape of the lifting groove formed at the top of multiple profiling lifting assemblies 10 matches the outer wall size of the cable, and then wind the cable in the same manner as in Step 1.
