Description

Technical Field

[0002] The electric tension machine is an important mechanical equipment used in power grid construction. It works with the traction machine to provide traction and tension for the conductor, allowing the conductor to fly into the air. Compared with the traditional hydraulic tension machine, the electric tension machine has significantly improved the sensitivity of tension control, and can achieve millisecond-level tension control with a deviation reduced to 1%.

[0003] Publication No. CN118249252B discloses an electric tension machine for overhead transmission lines, comprising a frame, a wheel set installed on the frame and used to transport conductors, a power generation unit that generates electricity using the rotational motion of the wheel set, and a battery pack for storing electrical energy; by utilizing the resistance during power generation to provide tension for the traction work of the conductor, it is convenient to partially recover the energy consumed by the traction machine, thereby avoiding energy loss when the tension machine itself provides tension for the conductor, realizing resource recycling and reuse, and improving the overall energy efficiency of the operation. At the same time, the complex hydraulic system is abandoned and an electric drive method is adopted, which not only simplifies the mechanical structure of the equipment, but also may reduce the overall weight, facilitates on-site disassembly and transportation, and improves the flexibility and efficiency of construction.

[0004] The placement of the electric tension machine is closely related to the wear during the cable tension adjustment process: Ground stability: When the electric tension machine is not placed stably, vibration and swing will occur during the operation of the equipment, resulting in uneven force on the cable during the tension adjustment process, increasing cable wear; Placement environment: Extreme weather such as strong winds and rainfall will interfere with the normal operation of the equipment, causing unstable force on the cables and increasing cable wear.

[0005] When adjusting the cable tension, the existing electric tension machine needs to first determine the position of the electric tension machine. For example, the electric tension machine for the overhead transmission line mentioned above adjusts the structure for easy disassembly and transportation, but the electric tension machine still needs to first determine the installation position and then adjust the cable. The cable tension cannot be adjusted at any position. Summary of the invention

For the purpose of clear description, many practical details will be described together in the following description. However, it should be understood that these practical details should not be used to limit the present invention. In other words, in some embodiments of the present invention, these practical details are not necessary.

Furthermore, the definitions of the above words in commonly used dictionaries should be interpreted in the content of this specification as consistent with the meanings of the relevant fields of the present invention. Unless otherwise clearly defined, these words will not be interpreted as idealized or overly formal meanings.

[0027] The following is an explanation of the relationships and terms used in this application: Parallel: The parallelism defined in this application is not limited to absolute parallelism. This definition of parallelism can be understood as basic parallelism, which allows for non-absolute parallelism due to factors such as assembly tolerance, design tolerance, and the influence of structural flatness.

It allows for non-absolute vertical intersection relationships caused by factors such as assembly tolerance, design tolerance, and influence of structural flatness. It also allows for errors in a small angle range. For example, the assembly error range of 80 to 100 degrees can be understood as a vertical relationship.

[0029] Floor: The floor defined in this application is not limited to a certain material or region, but only a platform for carrying this application, and stacking, tilting, and flatness changes are allowed. For example, cement floor, tile floor, work platform, etc. can all be interpreted as floor.

[0030] The above explanation does not completely include the relationship definitions given in this application, but only represents part of it.

[0031] The present invention provides an electric tension machine, which is used to install cables and provide traction and tension for the cables. The electric tension machine can be driven by a traction vehicle to move to a corresponding position.

[0032] See also Figure 1-2 as well as Figure 4 As shown, in one embodiment, the electric tension machine includes a body 1 that plays a main supporting role, a traction system 2 located inside the body 1 for realizing cable tensioning and movement, and a control system 3 for controlling the electric tension machine, the control system 3 also includes a sensor unit for real-time monitoring of cable tension, speed and position, the traction system 2 clamps the cable and controls the movement of the traction system 2 through the control system 3.

[0033] The electric tension machine also includes: A top frame 4, located on the upper part of the traction system 2 and detachably connected to the body 1, the top frame 4 comprises at least two support seats 41 connected to the body 1 and at least one frame plate 42, one end of the frame plate 42 is installed on the inner side of the support seat 41 through a rotating shaft and can rotate about the axis of the rotating shaft; A rotating table 5 is installed on the top of the frame plate 42. The rotating table 5 is equipped with a positioning disk 51 that can be wound with a cable. The rotating table 5 can drive the positioning disk 51 to rotate. An annular frame 52 is arranged outside the positioning disk 51. The annular frame 52 is fixed to the outer surface of the frame plate 42 and is coaxially arranged with the rotating table 5. A slide 6 that rotates along the annular frame 52 is arranged outside the annular frame 52. A traction head 7 is arranged outside the slide 6. The cable passes through the traction head 7 and extends outward. The slide 6 determines the traction angle based on the electric tension machine. The driving member 8 is installed inside the slide 6. The output end of the driving member 8 is connected to the slide 6. When the cable is offset based on the traction angle, the driving member 8 changes the position of the slide 6 to compensate for wear.

[0034] In one feasible method, when adjusting the cable tension, it is necessary to keep the traction angle between the electric tension machine and the cable within a certain range. Therefore, the electric tension machine can only be set within the corresponding position range. Due to the limitations of the cable installation position and the ground conditions, some complex terrain conditions make it inconvenient to fix the electric tension meter at a specific angle. By setting the positioning plate 51 and the rotatable slide 6, adjustments can be made according to the traction angle between the electric tension machine and the cable.

[0035] By utilizing the multi-angle movable slide 6 and the traction head 7 installed on the outside of the slide 6, it is possible to rotate around the axis of the turntable 5. When the electric tension machine adjusts the cable tension, it is not restricted by the swing position of the electric tension machine and the cable tension can be adjusted. When the traction angle between the cable and the electric tension machine is large, it will not cause problems such as uneven cable tension, increased bending stress and increased wear.

[0036] Among them, since the electric tension machine is affected by the ground stability and the placement environment during the operation of the equipment, the driving member 8 is used to compensate for the wear of the cable traction to avoid uneven force during the cable traction process, further ensuring the stability of the cable traction.

[0037] See also Figure 2-5 As shown, in one embodiment, a guide groove 43 is provided on one side of the machine body 1, and the guide groove 43 corresponds to the position of the frame plate 42, and the two sides of the frame plate 42 are adapted to the shape of the inner side of the guide groove 43. A long groove 44 is provided on the inner side of the frame plate 42, and the groove width of the long groove 44 is adapted to the diameter of the rotating shaft. The frame plate 42 can be retracted inside the guide groove 43, and the frame plate 42 is perpendicular to the ground when in a retracted state, and is parallel to the ground when in use; A buffer plate 45 is disposed at the bottom of the guide groove 43 , and the buffer plate 45 contacts the frame plate 42 and plays a buffering role. An extrusion block 46 protruding inwardly in an arc shape is disposed at the end of the guide groove 43 , and the extrusion block 46 is extruded and deformed when the frame plate 42 is inserted into the guide groove 43 .

[0038] In one feasible manner, the guide groove 43 is configured to facilitate the storage of the frame plate 42. During the transportation of the electric tension machine, the frame plate 42 is located on one side of the electric tension machine. After the frame plate 42 is opened, it is convenient to comb the cables inside the traction system 2. At this time, the frame plate 42 is located on one side of the machine body 1, and the traction system 2 is no different from the ordinary electric tension machine. Therefore, the frame plate 42 will not cause any impact when combing the cables.

[0039] Due to the rotating table 5 installed on the shelf 42, when the shelf 42 moves and is stored in the guide groove 43, the extrusion block 46 and the buffer plate 45 are used to increase the friction of the shelf 42, and when the shelf 42 moves to the bottom of the guide groove 43, no collision will occur, thereby protecting the shelf 42.

[0040] See also Figure 4 as well as Figure 9-10As shown, in one embodiment, a slide 47 is arranged on one side of the frame plate 42, the slide 47 is fixed on the inner side of the frame plate 42, and a positioning frame 48 is installed on the outer side of the screw rod inside the slide 47 and drives the positioning frame 48 to slide along the extension direction of the screw rod axis, a support member 49 is arranged on the outer side of the positioning frame 48, and the support member 49 can swing forward and backward within a certain arc, and the cable passes through the inside of the support member 49; The support member 49 is composed of a plurality of independent support bodies 491, which are connected by connecting members 493. The connecting members 493 limit the swing angles of adjacent support bodies 491. A support head 492 is arranged inside the support body 491. The support head 492 can be rotatably installed on the inner side of the support body 491. The support head 492 contacts the cable to support the cable.

[0041] In one feasible method, when the cable enters the inner side of the positioning plate 51 from the traction system 2, the cable may be excessively twisted due to the different cable entry angles. The cable is supported by the support member 49 so that the cable can bend to a certain extent to avoid excessive bending stress on the cable.

[0042] The arrangement of multiple support bodies 491 connected to each other can, when in use, allow the support bodies 491 to be bent to different angles according to the restrictions of the connecting parts 493 on the support bodies 491, thereby ensuring the support effect for the cables and ensuring that the cables will not be damaged when entering the positioning plate 51 from the traction system 2.

[0043] See also Figure 11-14 As shown, in one embodiment, the connector 493 includes: The connecting frame 4931 is arranged outside the supporting body 491. The supporting body 491 extends to the inside of the connecting frame 4931, and the supporting body 491 can rotate relative to the connecting frame 4931. A plurality of electromagnetic blocks 4932 are arranged inside the connecting frame 4931. The electromagnetic blocks 4932 are arranged in a circular array with the rotation center of the supporting body 491 and the connecting frame 4931; Plug 4933 is slidably arranged inside the connecting frame 4931. The plug 4933 is magnetically arranged and corresponds to the position of the electromagnetic block 4932. The change of the magnetic pole of the electromagnetic block 4932 changes the telescopic state of the plug 4933. When the plug 4933 is separated from the electromagnetic block 4932, the support body 491 is limited. A slot 4934 corresponding to the plug 4933 is arranged on the inner side of the support body 491. The plug 4933 extends into the slot 4934 to limit the swing angle of the support body 491.

[0044] In one feasible method, since a plurality of support bodies 491 need to form an arc shape, the support bodies 491 are connected via a connector 493, which serves to limit the support bodies 491. When determining the state of the cable, the cable is supported, and the connector 493 is limited via a plug 4933 to ensure the stability of the connector 493 and to limit the swinging amplitude of the support body 491, thereby ensuring the stability of the support body 491.

[0045] Among them, the electromagnets are symmetrically arranged. When the plug 4933 is used to limit the swing angle of the support body 491, the two sides are correspondingly inserted into the card slot 4934. The opening angle of the card slot 4934 is greater than the configuration angle of the plug 4933. Different plugs 4933 inserted into the card slot 4934 correspond to different swing angle ranges of the support body 491.

[0046] See also Figure 10-11 as well as Fig.13 As shown, in one embodiment, the positioning frame 48 includes a base frame 481 connected to the screw rod and a clamping plate 482 installed on the inner side of the base frame 481 and capable of rotating relative to the base frame 481, wherein a connecting member 493 is installed on the inner side of the clamping plate 482, and a magnetic plate matrix composed of an outer magnetic plate and an inner magnetic plate is arranged between the clamping plate 482 and the base frame 481, and the outer magnetic plate and the inner magnetic plate are both arranged in an annular manner; Pressure monitoring sensors 410 are arranged inside the support bodies 491 at both ends of the support member 49. The pressure monitoring sensors 410 are arranged in multiple directions to monitor the pressure between the cable and the monitoring end of the pressure monitoring sensor 410, and the curvature range of the support member 49 is determined based on the cable pressure.

[0047] In one feasible method, a magnetic plate matrix is ​​arranged between the base frame 481 and the card plate 482. When in use, the mutual magnetic attraction force of the magnetic plate matrix is ​​utilized to ensure the stability of the card plate 482 and the base frame 481. When the cable traction force is too large and greater than the magnetic attraction force between the magnetic plate matrices, the card plate 482 will rotate, and the cable traction force will be reduced, and the magnetic plate matrix will be utilized again for positioning.

[0048] Among them, the setting of the pressure monitoring sensor 410 monitors the pressure of the cable when it enters the inner side of the support body 491 during the cable pulling process, and adjusts the curvature range of the support body 491 according to the pressure to avoid excessive bending stress of the cable.

[0049] In another embodiment, the magnetic plate matrix can be replaced by a servo motor, which is fixed inside the base frame 481 , and its output end is connected to the card plate 482 to drive the card plate 482 to rotate, thereby adjusting the swing angle of the support member 49 .

[0050] See also Figure 6-8As shown, in one embodiment, a coaxial ring 53 is provided on the inner side of the positioning disk 51, and the ring 53 rotates relative to the positioning disk 51. The cable adheres to the outer surface of the ring 53, and at least one partition 54 is arranged on the inner side of the ring 53. The partition 54 is an open-loop arrangement, and the partition 54 is used to increase the number of turns of the cable around the surface of the ring 53.

[0051] In one feasible method, a rotatable ring 53 is provided on the surface of the positioning disk 51, and the cable is wound around the outside of the ring 53. The rotation of the ring 53 can reduce the friction of the cable, and the winding direction of the cable can be adjusted according to the placement position of the electric tension machine, thereby avoiding that the traction angle between the cable and the electric tension machine is too large.

[0052] See also Figure 15-18 As shown, in one embodiment, the traction head 7 comprises: The mounting portion 71 is hollow, and an adjusting portion 72 is arranged at one end of the mounting portion 71. One end of the adjusting portion 72 is spherical and extends into the interior of the mounting portion 71. The adjusting portion 72 can swing relative to the mounting portion 71. The mounting portion 71 and the adjusting portion 72 are both provided with spring pieces 73 for supporting the cable on the inner sides. The spring pieces 73 are arranged in an arc shape and respectively connect the mounting portion 71 and the adjusting portion 72. The cable is pulled to squeeze the spring pieces 73. An elastic cavity 74 is disposed in the middle of the mounting portion 71 , one end of the elastic cavity 74 passes through the mounting portion 71 and extends to the outside of the mounting portion 71 , and the other end of the elastic cavity 74 extends into the adjusting portion 72 and is not connected to the inner wall of the adjusting portion 72 ; A positioning tube 75 is disposed outside the mounting portion 71 , and an extrusion portion 76 is disposed outside the adjusting portion 72 . The extrusion portion 76 extends into the interior of the positioning tube 75 . The adjusting portion 72 swings through the extrusion portion 76 to extrude the medium inside the positioning tube 75 .

[0053] In one feasible manner, the adjustment portion 72 is bent relative to the mounting portion 71, and the state of the adjustment portion 72 is changed according to the pulling direction of the cable, and the change of the adjustment portion 72 is used to support the cable to prevent the cable from being worn when being pulled. The positioning tube 75 and the extrusion portion 76 are both configured in multiple numbers and set at different angles. The adjustment portion is bent at different angles, which can change the medium inside the positioning tube 75, thereby changing the state of the adjustment portion 72 and the elastic cavity 74 inside the mounting portion 71.

[0054] Among them, the mounting portion 71 and the adjusting portion 72 are both tubular in shape, and one end of the mounting portion 71 and the adjusting portion 72 are both spherical in shape, which will not limit the swinging direction of the cable, thereby avoiding the problem that the cable is pulled at a specific angle and the adjusting portion 72 cannot be changed to the corresponding angle.

[0055] See also Figure 17-19As shown, in one embodiment, the extrusion portion 76 is composed of an extrusion end 762, a connecting end 761 and a push block 763. The end of the push block 763 is a concave spherical surface and contacts the extrusion end 762. The extrusion end 762 is spherical, and the two ends of the connecting end 761 are respectively connected to the extrusion end 762 and the adjustment portion 72.

[0056] In one feasible method, the connecting end 761 is used to connect the extruding end 762 to the adjusting portion 72. When in use, the adjusting portion 72 swings to pull the push block 763 through the connecting end 761, causing the push block 763 to move and change position. The positioning tube 75 is connected to the elastic cavity 74 and is filled with a medium. After the push block 763 moves and changes, the medium pressure can change. The positioning tube 75 is hard and the elastic cavity 74 is flexible. Therefore, the elastic cavity 74 will shrink or expand.

[0057] The push block 763 is magnetic and magnetically attracts the extrusion end 762. When the position of the extrusion end 762 changes, the position of the push block 763 will also change synchronously.

[0058] See also Figure 17-20 As shown, in one embodiment, the driving member 8 includes: The inclination sensor 81 is installed inside the slide 6. A positioning rod 82 is arranged outside the mounting portion 71 and extends into the inside of the slide 6 and is connected to the slide 6. The positioning rod 82 drives the mounting portion 71 to swing relative to the slide 6. The positioning ring 83 is located inside the slide 6 and is sleeved on the outside of the positioning rod 82. A push rod 84 is arranged on the outside of the positioning ring 83 to support the positioning ring 83. An electromagnetic assembly 85 is arranged between the push rod 84 and the slide 6. The electromagnetic assembly 85 includes two electromagnets respectively installed on the outside of the push rod 84 and the inner wall of the slide 6. The electromagnets cooperate to change the position of the push rod 84, the push rod 84 changes the position of the positioning ring 83, and the positioning ring 83 changes the swing angle of the positioning rod 82 compared to the slide 6.

[0059] In one feasible method, the inclination sensor 81 can monitor the angle of the electric tension machine during use. When the angle of the electric tension machine changes, the inclination sensor 81 detects the angle deviation of the electric tension machine, and uses an electromagnet to cooperate to change the position of the push rod 84, so that the push rod 84 pushes the positioning ring 83 to change, so as to adjust according to the traction angle of the cable.

[0060] The positioning ring 83 can move within a certain range with the support of the top rod 84, thereby supporting the positioning rod 82 to tilt to different angles. According to the pulling angle of the cable, the positioning rod 82 needs to be changed to different tilt angles. Therefore, the inner side of the positioning ring 83 is set to be an arc shape, and the positioning rod 82 is supported by the arc surface of the positioning ring 83, which can ensure the contact stability between the positioning ring 83 and the positioning rod 82.

[0061] The present application also provides an electric tension machine control system 3, which is used for the above electric tension machine, and the control system 3 includes: The sensor unit is arranged on the cable's insertion path to monitor the cable's traction force; A traction system 2, used for traction of the cable; A driving system for controlling the position of the traction head 7 via a driving member 8; The transmission unit is used to control the wireless communication between the system 3 and the terminal device, transmit the sensor unit data, and control the traction system 2 and the drive system to make corresponding adjustments based on the adjustments of the terminal device.

[0062] Although the present invention is disclosed in conjunction with the above embodiments, it is not intended to limit the present invention. Anyone familiar with this technology can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the definition of the attached claims.
