Description

Technical Field

[0001] The present invention relates to the technical field of cable performance detection, and in particular to a transmission line cable performance detection device. Background Art

[0002] Cable is a key link in power transmission, and its performance testing is crucial to ensure the safety and stability of urban power supply. With the continuous advancement of technology and the growing demand, cable performance testing devices are developing in the direction of intelligence, high precision, remoteness, modularization, customization and greenness. At the same time, cable performance testing needs to comprehensively evaluate its electrical performance, mechanical properties, heat and aging resistance, combustion performance, appearance and size, as well as dielectric loss and insulation performance. Among them, insulation testing is a key part of cable performance testing.

[0003] With the development of technology, insulation inspection devices have been greatly developed. For example, a Chinese patent (publication number: CN115144713B) discloses a transmission line cable insulation performance detection device and a detection method, which belongs to the field of cable insulation performance detection technology, including two symmetrically arranged bases and a winch, the bottom surface of the base is slidably connected with a detection platform, the outer side of the cable sleeve is wrapped with a cable, and a plurality of detection ports are arranged on the detection platform. The detection port includes a detection frame, and the inner side of the detection frame is connected with a first transmission wheel and a second transmission wheel. The lower surface of the first transmission wheel is provided with a first detection point, and the upper surface of the second transmission wheel is provided with a second detection point. The first detection point and the second detection point are connected with a detection circuit, and accurate detection can be achieved for the damaged and leaking cable part. By setting a plurality of detection ports to detect different parts of the cable, and by continuously winding the cable through the winch, the entire cable part can be effectively detected before the cable is laid, without affecting the cable laying process.

[0004] When the device is in use, the front end of the base is used as a support point, and the rear end of the base is lifted so that the base and the detection platform are at the same inclination angle, and the head of the cable is passed through the detection port. After passing through, the cable is transmitted between the first transmission wheel and the second transmission wheel, and the head of the cable is towed by the traction rope driven by the winch. The first detection point and the second detection point on the first transmission wheel and the second transmission wheel detect the insulation performance of the cable. The winch works intermittently during the detection. When the cable leaks, the detection circuit is turned on and the sound and light alarm alarms. The controller drives the swinging marking mechanism to mark the cable. However, when the device is used, the cable is only pulled by the winch, which is prone to uneven cable winding. At the same time, a large number of cables are easily squeezed against each other, resulting in cable knots. At the same time, it is very inconvenient to take and put after the installation is completed, which may affect the subsequent work progress. Summary of the invention

[0019] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0020] 1. For the power transmission line cable performance detection device, during use, first pass the cable through the axles of the five detectors, place the cable on the spool and clamp it with the clamping plates, and then start the traction mechanism to continuously pull the cable through the detectors for insulation detection. At the same time, the transmission component transmits the power of the servo motor to the rotating shaft, causing the rotating shaft to rotate and drive the wire arranging cylinder to rotate. At this time, the chute will push the mobile detection part to continuously move back and forth as the rotating shaft rotates, so as to achieve the purpose of uniform wire arrangement, avoiding the problem that the cable is largely wound and knotted at a certain place due to single power, thus providing better conditions for subsequent work and improving work efficiency.

[0021] 2. For the power transmission line cable performance detection device, when the detection is completed, at this time the cable is evenly wound on the left spool. Just remove the spool and it can be directly used without restoration. At the same time, when disassembling, start the lifting component. At this time, the four supporting parts will continuously rise under the drive of the stepping motor, causing the supporting parts to continuously approach the spool to complete the support.

[0022] 3. In the process of the continuous rising of the supporting part of the cable performance detection device for the transmission line, the rotating rod will also rotate synchronously. Since the rising path of the supporting part is greater than the contracting paths of the transmission rod and the self-locking rod, during the initial rising process of the supporting part, the pulling rope is in a relatively loose state and is continuously wound up. Therefore, the pulling rope will not pull the transmission rod and the self-locking rod until it changes from the loose state to the tensioned state. At this time, when the supporting part is about to contact the spool, and at the same time, the transmission rod and the self-locking rod are just pulled apart. At this time, the two spools are just in the unlocked state and are located on the supporting part. Opening the movable plate on the supporting part can directly remove the spool. This structure is convenient for loading and unloading, can greatly simplify the loading and unloading steps, and can directly take away the cable when it is needed later, which can improve the overall working efficiency.

Detailed implementation manners

[0031] 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.

[0032] Please refer to Figures 1 to 3 and Figure 7 , a power transmission line cable performance detection device in this embodiment includes a base 1. Baffles 2 are fixed on both the left and right sides of the base 1. Two partition boards 3 are fixed on the top of the base 1. A loading and unloading mechanism 4 for assisting in the installation and disassembly of the cable is provided between the two baffles 2. A traction mechanism 5 for providing power to assist in cable detection is provided on the back of the partition board 3 located at the rear. A detection assembly 6 for detecting the insulation performance of the cable is provided between the two partition boards 3.

[0033] In addition, the loading and unloading mechanism 4 includes a stepping motor 401 fixed to the outer side of the left baffle 2. A driving rod 402 is fixed to the output shaft of the stepping motor 401. A gear train assembly is provided on the outer surface of the driving rod 402. The gear train assembly includes two driven rods 403 rotatably connected to the two baffles 2 through bearings. A driving gear 404 is fixed to the outer surface of the driving rod 402. Driven gears 405 are fixed to the outer surfaces of the two driven rods 403. The driving gear 404 meshes with the two driven gears 405. Lifting assemblies 406 and locking assemblies 407 are fixed to the outer surfaces of the two driven rods 403. Self-locking rods 408 are movably connected to both of the two partition plates 3. The movable connection of the self-locking rods 408 can ensure the smooth expansion and contraction of the self-locking rods 408, thereby achieving the two purposes of jamming and unlocking.

[0034] It should be specifically noted that the driving rod 402 penetrates through the left baffle 2 and is rotatably connected to the inner side wall of the right baffle 2 through a bearing. Four threaded strips are fixed to the outer surfaces of the two driven rods 403. The two threaded strips on the left side of each driven rod 403 have opposite helix directions, and the two threaded strips on the right side also have opposite helix directions. The lifting assembly 406 includes eight threaded hinge blocks 4061 that are adapted to and threadedly connected to the threaded strips on the outer surfaces of the two driven rods 403. A limiting block is fixed to the bottom of each threaded hinge block 4061. A connecting rod 4062 is hinged to the top of each threaded hinge block 4061. One end of each connecting rod 4062 away from the threaded hinge block 4061 is hinged to a fixed hinge block 4063. A supporting part 4064 is fixed to the top of every two fixed hinge blocks 4063. Each supporting part 4064 includes an outer plate fixed to the two fixed hinge blocks 4063. A supporting plate is fixed to the inner side of the outer plate. A movable plate is hinged to the bottom of the supporting plate. Threaded holes are formed in both the movable plate and the outer plate. A bolt is threadedly connected to the two threaded holes. The movable plate is fixed to the outer plate through the bolt. The fixing and movement of the movable plate can be realized through the bolt, which can ensure the supporting stability and facilitate loading and unloading at the same time. The setting of multiple groups of reverse threaded strips can cause the threaded hinge blocks 4061 on different threaded strips to move in different directions under the same rotation direction, and the limiting blocks are used to prevent the threaded hinge blocks 4061 from rotating with the threaded strips, so that the supporting part 4064 can move up and down smoothly.

[0035] It can be known that the locking assembly 407 includes two worm gears 4071 fixed to the outer surface of the driven rod 403. On the opposite sides of the two worm gears 4071, there are worm wheels 4072 meshed respectively. At the axles of the two worm wheels 4072, there are rotating rods 4073 fixed respectively. The bottoms of the two rotating rods 4073 are rotatably connected to the base 1 through bearings. On the outer surface of each rotating rod 4073, there are two pulling ropes 4074 fixed respectively. On the opposite sides of the two partition plates 3, there are stabilizing blocks 4075 and trapezoidal fixing blocks 4076 fixed respectively. Inside each stabilizing block 4075 and trapezoidal fixing block 4076, there is a fixed pulley 4077 rotatably connected. On the opposite sides of the two pulling blocks, they are fixed to the pulling ropes 4074. On the opposite sides of the two self-locking rods 408, they are fixed to the pulling ropes 4074. The four pulling ropes 4074 all wind around the outside of the fixed pulley 4077, and the four pulling ropes 4074 are all in a relatively loose state, which can make the unlocking have hysteresis and prevent the unlocking from occurring before the supporting part 4064 approaches.

[0036] In this embodiment, through the cooperation of the lifting assembly 406 and the locking assembly 407, the device can be loaded and unloaded smoothly. When the lifting assembly 406 rises, the locking assembly 407 will not be unlocked immediately, but will be unlocked with a delay, so that when the lifting assembly 406 is basically in contact with the spool 504, it will be unlocked, thus ensuring the safety of loading and unloading.

[0037] Please refer to again Figure 3 and Figure 4 In order to continuously provide power for cable detection, in this embodiment, the traction mechanism 5 includes a servo motor 501 fixed to the rear side of the outer surface of the partition plate 3. The output shaft of the servo motor 501 is fixed with a transmission assembly 502 for transmitting the power output by the servo motor 501. Inside the transmission assembly 502, there is a transmission rod 503. The outer surface of the transmission rod 503 is meshed with a spool 504. The front side of the spool 504 is meshed with the transmission rod 503. The spool 504 is placed inside the supporting part 4064 and does not penetrate to its outside.

[0038] In addition, the transmission assembly 502 includes a driving shaft 5021 fixed to the output shaft of the servo motor 501. The driving shaft 5021 is rotatably connected to the partition plate 3 through a bearing. A driven shaft 5022 and a transmission shaft 5023 are rotatably connected to the back surface of the partition plate 3 at the rear. A cylindrical gear 5024 is fixed to the outer surface of the driving shaft 5021. A disc gear 5025 is fixed to the outer surface of the transmission rod 503 at the rear side. Transmission gears 5026 and large gears 5027 are respectively fixed to the outer surfaces of the driven shaft 5022 and the transmission shaft 5023. A sprocket portion 5028 is further provided on the outer surface of the transmission shaft 5023. The sprocket portion 5028 includes a driving sprocket, a driven sprocket and a chain. The driving sprocket is fixed to the outer surface of the transmission shaft 5023, and the driven sprocket is fixed to the outer surface of the rotating shaft 601. The driving sprocket and the driven sprocket are connected by chain drive. The transmission of the sprocket portion 5028 can ensure the transmission stability while increasing the transmission distance, thereby reducing the weight of the device.

[0039] It should be further noted that the two transmission rods 503 respectively penetrate through the two partition plates 3. Two compression holes are formed in each of the two partition plates 3. Thrust bearings are fixed on the outer sides of the two transmission rods 503 and located within the compression holes. Springs are fixed to the opposite sides of the two thrust bearings. The opposite sides of the two springs are fixed to the partition plates 3. Thrust bearings are fixed on the outer surfaces of the two self-locking rods 408 and located within the compression holes. Springs are fixed to the opposite sides of the two thrust bearings. The sides of the two springs away from the self-locking rods 408 are fixed to the partition plates 3. A spool 504 is movably connected between the two self-locking rods 408. Bearings are fixed to the opposite sides of the two transmission rods 503. Pulling blocks are fixed to the opposite sides of the two bearings. Since thrust bearings are fixed on the outer sides of the transmission rods 503 and the springs are respectively fixed to the thrust bearings and the partition plates 3, the springs can be protected from rotating with the transmission rods 503.

[0040] It can be known that the spool 504 includes two support discs respectively meshing with the two transmission rods 503. A drum is fixed between the two support discs. Clamping plates are hinged to the outer surface of the drum. The setting of the clamping plates can stabilize the cable and assist the cable to be wound smoothly.

[0041] It should be noted that the clamping plates assist the cable to be wound smoothly, which is convenient for subsequent traction. The traction mechanism 5 continuously urges the cable to be detected. By setting the thrust bearings, the springs are separated from the self-locking rods 408 and the transmission rods 503 to protect the springs.

[0042] Please refer to Figures 5 to 6 , in order to make the wire arrangement uniform, the detection assembly 6 in this embodiment includes a rotating shaft 601 penetrating through the two partition plates 3. A wire arranging cylinder 602 is fixed to the outer surface of the rotating shaft 601. A limiting disc 603 is fixed to the front surface of the rotating shaft 601. A moving detection portion 604 is provided at the top of the rotating shaft 601.

[0043] In addition, a chute is provided on the cable arranging cylinder 602. The moving detection part 604 includes a sliding piece 6041 movably connected to the chute. A tool holder 6042 is fixed to the top of the sliding piece 6041. A connecting bearing 6043 is fixed to the top of the tool holder 6042. A detection seat 6044 is fixed to the top of the connecting bearing 6043. Two limiting holes are provided inside the detection seat 6044. Limiting rods 6045 are movably connected to both of the two limiting holes. Both of the two limiting rods 6045 are fixed to the opposite sides of the two partition plates 3. Five detectors 6046 are fixed to the top of the detection seat 6044. The five detectors 6046 can ensure the correctness of detection. The sliding piece 6041 moves continuously in the chute, and together with the two limiting rods 6045, it causes the detection seat 6044 to move continuously, promoting the uniform winding of the cable during the detection process.

[0044] In this embodiment, by continuously rotating the cable arranging cylinder 602, the sliding piece 6041 is caused to move continuously, further causing the detection seat 6044 to move back and forth continuously during the detection process, making the cable arranging uniform.

[0045] It can be understood that the lifting component 406 in the loading and unloading mechanism 4 cooperates with the locking component 407 to achieve safe loading and unloading. During use, the traction mechanism 5 continuously tractions while the transmission component 502 transmits power to the detection component 6 to promote the cable to be arranged while being detected, which can save a lot of time for subsequent use.

[0046] All the electrical components mentioned in the text are electrically connected to the controller and the power supply. The control mode of the present invention is controlled by the controller. The control circuit of the controller can be realized by simple programming by those skilled in the art. The provision of the power supply also belongs to the common knowledge in the art. And the present invention mainly aims to protect the mechanical device, so the control mode and the circuit connection of the present invention will not be explained in detail.

[0047] The working principle of the above embodiment is as follows:

[0048] (1) During use, the cable is passed through the five detectors 6046, and then the cable is fixed by the clamping plate. The servo motor 501 is started. The power is transmitted from the cylindrical gear 5024 through the disk gear 5025 to the transmission rod 503, thereby causing the spool 504 to rotate, continuously traction the cable, and causing the cable to continuously pass through the detectors 6046 to realize the detection of the insulation of the cable. At the same time, the power of the servo motor 501 will also be transmitted from the transmission gear 5026 through the large gear 5027 to the sprocket part 5028, and further transmitted to the rotating shaft 601 to cause the rotating shaft 601 to rotate continuously, so that the cable arranging cylinder 602 rotates continuously. Since the chute and the sliding piece 6041 are movably connected, it further pushes the sliding piece 6041 to move back and forth continuously, and together with the traction of the spool 504, it promotes the cable to be evenly wound onto the spool 504.

[0049] After the detection is completed, the servo motor 501 is turned off while the stepping motor 401 is started. The power of the stepping motor 401 is transmitted from the driving gear 404 on the driving rod 402 to the two driven gears 405, prompting the two driven rods 403 to rotate synchronously, causing the threaded hinge block 4061 to move on the driven rod 403, and causing the connecting rod 4062 to rotate to lift the supporting part 4064, so that the supporting part 4064 continuously approaches the spool 504. During the lifting process of the supporting part 4064, the power of the stepping motor 401 is also synchronously transmitted to the two rotating rods 4073 through the worm 4071 and the worm gear 4072. Since the pull rope 4074 is relatively loose at the beginning, the rotation of the rotating rod 4073 at the initial stage only tightens the pull rope 4074. During the process of the pull rope 4074 being gradually tightened, the supporting part 4064 continuously approaches the spool 504. When the supporting part 4064 is very close to the spool 504, the pull rope 4074 is tightened. When the supporting part 4064 touches the spool 504, the pull rope 4074 just pulls both the two transmission rods 503 and the self-locking rod 408 apart, thereby prompting the unlocking of the two spools 504. Then, the bolts are unscrewed, and the movable plate is lowered to remove the spool 504. This structure is convenient for loading and unloading, time-saving and labor-saving, and can greatly improve the docking work between the detection completion and the subsequent links.

[0050] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.

[0051] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
