[0002] The charging pile cable is a key component connecting the charging pile and new energy vehicles. It is not only responsible for transmitting electrical energy, but also carries the important task of ensuring the safety of the charging process, which is directly related to the charging efficiency and safety of new energy vehicles; armored cable, also known as PVC insulated PVC sheathed steel belt armored power cable, is a cable that can be directly buried underground. The armor mechanical protection layer can increase the mechanical strength of the internally sheathed cable and improve its anti-corrosion ability. It is designed for areas that are susceptible to mechanical damage and extremely susceptible to erosion. In the process of adding armor to the cable production, the outer surface of the inner sheath of the insulated cable is wrapped with galvanized steel belt by a steel belt armoring machine to add a protective armor layer to the cable, and a PVC outer sheath is sheathed on the outer surface of the armor, thereby completing the wrapping process of the outer side of the inner sheath of the cable. After the cable processing and winding are completed, the armor strength of the cable needs to be inspected.

[0015] The present invention also provides a charging pile cable armor sampling inspection method, which is performed by the following steps:

[0016] S1. When spot-checking the armored cable, place the armored cable on the spot-checking table, insert one end of the armored cable into the cylinder, and then start the cylinder to drive the cutter and the horizontal plate to move downward at the same time. The horizontal plate drives the first tooth groove on the driving plate to move downward through the first L-shaped plate and mesh with the large gear, so that the large gear rotates;

[0017] S2. When the large gear rotates, the driving rod will slide along the arc-shaped sliding hole on the surface of the large gear, and then the three driving rods will drive the sliding rod to slide toward the inside of the cylinder at the same time, thereby driving the three clamping plates to clamp the armored cable at the same time, so as to achieve fixation between the random inspection and shearing of the armored cable. At the same time, when the top of the driving plate is separated from the large gear, the cylinder drives the cutter to shear the armored cable, which helps to make the cable random inspection process more stable and prevent the armored cable from bending more during shearing.

[0018] Compared with the prior art, the present invention provides a charging pile cable armor sampling inspection device and method, which has the following beneficial effects:

[0019] 1. The charging pile cable armor sampling inspection equipment inserts one end of the armored cable into the cylinder, and then starts the cylinder to drive the cutter and the cross plate to move downward at the same time. The cross plate drives the first tooth groove on the driving plate to move downward through the first L-shaped plate to mesh with the large gear, so that the large gear rotates. When the large gear rotates, the driving rod will slide along the arc-shaped sliding hole on the surface of the large gear, and then the three driving rods will drive the sliding rod to slide into the inside of the cylinder at the same time, thereby driving the three clamping plates to clamp the armored cable at the same time, so as to achieve fixation between the random inspection and shearing of the armored cable, make the cable sampling process more stable, and prevent the armored cable from bending more during shearing.

[0020] 2. The charging pile cable armor sampling inspection equipment, when the cylinder drives the cutter and the cross plate to move downward, the second tooth groove on the driving plate will first mesh with the small gear to make the small gear rotate, and the small gear drives the cam to rotate through the connecting tube. When the protruding part of the cam rotates to conflict with the contact plate, the contact plate and the push rod will move downward. When the push rod moves downward, it will drive the piston plate downward. At the same time, the second spring will be compressed, and a piston movement will be made inside the piston tube. Then, when the protruding part of the cam does not conflict with the contact plate, the contact plate and the push rod will move downward. The piston plate will automatically reset upward under the action of the second spring, so that the piston cylinder will suck in the air inside the piston cylinder through the suction pipe. Then, when the protruding part of the cam contacts the contact plate again, the piston plate will squeeze out the air inside the piston cylinder and enter the air collecting box through the air outlet pipe. Then, the air will be ejected through three sets of air blowing hoses. This reciprocating process will automatically remove the dust on the surface of the armored cable that has not been clamped in advance, so as to avoid the dust on the armored cable affecting the fixing effect of the armored cable and make the armored cable better and more stable when clamped.

[0021] 3. The charging pile cable armor sampling inspection equipment drives the cutter and the cross plate to reset to the initial position by starting the cylinder, and then retracts the cylinder upward to drive the cross plate upward to lift the circular plate upward. The circular plate drives the pull rope at the bottom to guide through the U-shaped guide wheel frame, and pulls the slide plate to slide along the slide plate and the second guide rod, so that the slide plate drives the rectangular plate and the rubber friction plate to slide in the direction of the cylinder, so as to automatically remove the cut armored cable and automatically push the cut armored cable to the outside of the sampling inspection table without manual unloading, which helps to improve the cable sampling efficiency.

[0036] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0037] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0038] Example 1: Reference Figure 1-Figure 13A charging pile cable armor sampling inspection device, comprising a sampling inspection platform 1 and an armored cable 2 arranged on the sampling inspection platform 1, a support frame 3 is fixedly installed on the top of the sampling inspection platform 1, a hydraulic sampling segmentation machine 4, a cylinder 5, and a cutter 6 are arranged on the support frame 3, a pushing mechanism 7 is arranged on the sampling inspection platform 1, and a horizontal plate 8 is fixedly connected to the output end of the cylinder 5, and also includes: a first L-shaped plate 9, which is fixedly connected to the side surface of the horizontal plate 8, and the end of the first L-shaped plate 9 away from the horizontal plate 8 is fixedly connected to a driving plate 10, and a first tooth groove 11 is opened on one side surface of the driving plate 10; a first U-shaped rod 12, which is fixedly connected to the side of the sampling inspection platform 1, and the first U-shaped rod 12 is away from the sampling inspection One end of the table 1 is rotatably connected to a large gear 13 that meshes with the first tooth groove 11, and an arc-shaped sliding hole 14 is opened on the surface of the large gear 13; a fixed rod 15 is fixedly connected to the top of the sampling table 1, and a cylinder 16 is fixedly connected to the top of the fixed rod 15. A sliding rod 17 passes through the surface of the cylinder 16 and is slidably connected to the cylinder 16. The end of the sliding rod 17 away from the cylinder 16 is fixedly connected to a driving rod 18 corresponding to the arc-shaped sliding hole 14, and a splint 19 is fixedly connected to the sliding rod 17 close to the inside of the cylinder 16. There are three groups of arc-shaped sliding holes 14, sliding rods 17, driving rods 18, and splints 19, and they are all arranged in a circular array on the surface of the cylinder 16.

[0039] In the present invention, when the armored cable 2 is sampled, one end of the armored cable 2 is inserted into the cylinder 16, and then the cylinder 5 is started to drive the cutter 6 and the horizontal plate 8 to move downward at the same time. The horizontal plate 8 drives the first tooth groove 11 on the driving plate 10 to move downward through the first L-shaped plate 9 to mesh with the large gear 13, so that the large gear 13 rotates. When the large gear 13 rotates, the driving rod 18 slides along the arc-shaped sliding hole 14 on the surface of the large gear 13, and then the three driving rods 18 simultaneously drive the sliding rod 17 to slide into the inside of the cylinder 16, thereby driving the three clamping plates 1 9 At the same time, the armored cable 2 is clamped, so that the armored cable 2 is fixed between sampling and cutting, making the cable sampling process more stable and preventing the armored cable 2 from bending more during cutting; it should be noted that the distance that the driving plate 10 moves downward causes the large gear 13 to rotate, so that after the armored cable 2 is clamped, the top of the driving plate 10 is just separated from the large gear 13, and when the cylinder 5 drives the cutter 6 to cut downward, the clamping plate 19 will not continue to clamp the armored cable 2; the first U-shaped rod 12 can support the large gear 13.

[0040] The driving rod 18 passes through the arc-shaped sliding hole 14 and is slidably connected to the arc-shaped sliding hole 14. The surface of the sliding rod 17 is sleeved with a first spring 21. The two ends of the first spring 21 are respectively fixedly connected to the driving rod 18 and the outer wall of the cylinder 16. The surface of the large gear 13 is provided with a circular groove corresponding to the first U-shaped rod 12.

[0041] In the present invention, when the first tooth groove 11 on the driving plate 10 causes the large gear 13 to rotate, the arc-shaped sliding hole 14 on the large gear 13 rotates to cause the driving rod 18 to slide, and when the sliding rod 17 is driven to slide into the cylinder 16, the first spring 21 is compressed. Similarly, when the armored cable 2 is released, the first spring 21 helps to reset the clamping plate 19 and the sliding rod 17 faster.

[0042] Example 2: Reference Figure 1-Figure 10 , which is basically the same as the first embodiment, and further, the pushing mechanism 7 includes a mounting plate 701, and the mounting plate 701 is fixedly connected to the surface of the sampling platform 1 on the side away from the support frame 3, and a motor 702 is fixedly installed on the surface of the mounting plate 701, and a screw 703 is fixedly connected to the output end of the motor 702, and the end of the screw 703 away from the motor 702 is rotatably connected to a bearing plate 704, and the bearing plate 704 is fixedly connected to the bottom of the sampling platform 1.

[0043] A push plate 705 penetrates the surface of the screw 703, and the push plate 705 is threadedly connected to the screw 703. A sliding hole matching the push plate 705 is opened on the surface of the sampling inspection table 1, and three groups of cable brackets 706 are fixedly connected to the top of the sampling inspection table 1.

[0044] In the present invention, when the armored cable 2 is randomly inspected, the armored cable 2 to be inspected is placed on the three sets of cable brackets 706 on the inspection table 1, one end of the armored cable 2 is against the push plate 705, and the other end is aligned with the inside of the cylinder 16, and then the motor 702 is started to drive the screw 703 to rotate, and then the screw 703 drives the push plate 705 on the surface to slide along the sliding hole of the inspection table 1, pushing the armored cable 2 toward the direction of the cylinder 16, so that the armored cable 2 is automatically fed. After the armored cable 2 is moved to a suitable position, the motor 702 is turned off to stop the movement of the armored cable 2, and then the shearing operation is performed.

[0045] The hydraulic sampling and segmenting machine 4 is fixedly connected to the support frame 3, the cylinder 5 is fixedly connected to the bottom of the hydraulic sampling and segmenting machine 4, the cutter 6 is fixedly connected to the output end of the cylinder 5, and two groups of first guide rods 20 are fixedly connected between the sampling platform 1 and the support frame 3. The first guide rods 20 pass through the cross plate 8 and are slidably connected to the cross plate 8.

[0046] In the present invention, the first guide rod 20 can play a guiding role in the process of the cylinder 5 driving the cutter 6 and the cross plate 8 to move downward, so that the cutter 6 and the cross plate 8 can move vertically downward stably. When the armored cable 2 is sampled and sheared, the cutter 6 is driven downward by starting the cylinder 5 to cut the armored cable 2.

[0047] Example 3: Reference Figure 1-Figure 11, which is basically the same as the first embodiment, and further, a second tooth groove 22 is opened on the side surface of the driving plate 10 away from the first tooth groove 11, a second L-shaped plate 23 is fixedly connected to the side surface of the support frame 3, and a piston cylinder 24 is fixedly connected to the end surface of the second L-shaped plate 23 away from the support frame 3, and a second U-shaped rod 25 is fixedly connected to the side surface of the sampling table 1 close to the first U-shaped rod 12, and a pinion 26 meshing with the second tooth groove 22 is rotatably connected to the end surface of the second U-shaped rod 25 away from the sampling table 1, and a cam 27 passes through the surface of the second U-shaped rod 25, and the cam 27 is rotatably connected to the second U-shaped rod 25, and a connecting cylinder 2701 is fixedly connected between the cam 27 and the pinion 26, and the connecting cylinder 2701 is sleeved on the second U-shaped rod 25, and the internal piston of the piston cylinder 24 is connected to the piston plate 28, and the top of the piston plate 28 is fixedly connected to the push rod 29.

[0048] The push rod 29 passes through the piston cylinder 24 and is slidably connected to the piston cylinder 24. A contact plate 30 is fixedly connected to the top of the push rod 29. A second spring 31 is sleeved on the surface of the push rod 29. The two ends of the second spring 31 respectively abut against the piston cylinder 24 and the contact plate 30. An intake pipe 32 is fixedly connected to the side surface of the piston cylinder 24. An air blowing hose 33 passes through the surfaces of the three groups of sliding bars 17 and the clamping plate 19. The air blowing hose 33 is fixedly connected to the sliding bars 17 and the clamping plate 19. The ends of the three groups of air blowing hoses 33 away from the clamping plate 19 are fixedly connected to an air collecting box 34. An air outlet pipe 35 is fixedly connected between the air collecting box 34 and the piston cylinder 24.

[0049] In the present invention, since some armored cables 2 are exposed to the outside for a long time or stored in a warehouse, some dust will be absorbed on the surface. At this time, while the cylinder 5 drives the cutter 6 and the cross plate 8 to move downward, the second tooth groove 22 on the driving plate 10 will first mesh with the pinion 26 to rotate the pinion 26, and the pinion 26 drives the cam 27 to rotate through the connecting tube 2701. When the protruding part of the cam 27 rotates to contact the contact plate 30, the contact plate 30 and the push rod 29 will move downward. When the push rod 29 moves downward, it will drive the piston plate 28 downward. At the same time, the second spring 31 will be compressed and a piston movement will be performed inside the piston cylinder 24. Subsequently, when the protruding part of the cam 27 does not contact the contact plate 30, the contact plate 30, the push rod 29 and the piston plate 28 will automatically move under the action of the second spring 31 The piston cylinder 24 is reset upward, so that the air inside the piston cylinder 24 is sucked in through the suction pipe 32. Then, when the protrusion of the cam 27 contacts the contact plate 30 again, the piston plate 28 squeezes out the air inside the piston cylinder 24 and enters the air collecting box 34 through the outlet pipe 35. The air is then ejected through the three sets of blowing hoses 33. This reciprocating motion can automatically remove dust on the surface of the armored cable 2 that has not been clamped in advance, and can prevent the dust on the armored cable 2 from affecting the fixing effect of the armored cable 2, so that the armored cable 2 can be clamped better and more stable. It should be noted that a one-way valve is installed inside the suction pipe 32 and the outlet pipe 35. The purpose is to prevent suction from the outlet pipe 35 when the piston cylinder 24 is inhaling, and to prevent ejection from the suction pipe 32 when the gas is ejected.

[0050] Example 4: Reference Figure 1-Figure 13 , which is basically the same as the first embodiment, and further, a hanging rope 36 is fixedly connected to the top surface of the inner side of the support frame 3, a circular plate 37 is fixedly connected to the bottom surface of the hanging rope 36, a pull rope 38 is fixedly connected to the bottom of the circular plate 37, and a through hole corresponding to the pull rope 38 is opened on the surface of the horizontal plate 8, a U-shaped guide wheel frame 39 is fixedly connected to the top surface of the sampling platform 1, a slide plate 40 is fixedly connected to the top surface of the sampling platform 1, a second guide rod 41 is fixedly connected to the inner walls on both sides of the slide plate 40, a slide plate 42 passes through the surface of the second guide rod 41, the slide plate 42 is slidably connected to the second guide rod 41 and the slide plate 40, and the end of the pull rope 38 away from the circular plate 37 is fixedly connected to the slide plate 42.

[0051] A third spring 43 is sleeved on the surface of the second guide rod 41, and the two ends of the third spring 43 are respectively against the inner walls of the slide plate 42 and the slide groove plate 40, a rectangular plate 44 is hinged on the side surface of the slide plate 42, a torsion spring 45 is fixedly connected between the bottom of the rectangular plate 44 and the slide plate 42, a baffle 46 is fixedly connected to the top side surface of the slide plate 42, the baffle 46 is located on the top of the rectangular plate 44, and a rubber friction plate 47 is fixedly connected to the end of the rectangular plate 44 away from the slide plate 42, and the rubber friction plate 47 is against the armored cable 2.

[0052] In the present invention, when the armored cable 2 is sampled, the armored cable 2 is placed on the rubber friction plate 47. The gravity of the armored cable 2 causes the rectangular plate 44 to compress the torsion spring 45 downward, so that the rubber friction plate 47 can be in close contact with the bottom of the armored cable 2. After the armored cable 2 is sheared, the cut armored cable 2 stays in the cylinder 16. At this time, the cylinder 5 is started to drive the cutter 6 and the cross plate 8 to reset upward to the initial position, and then the cylinder 5 is retracted upward again to drive the cross plate 8 upward to lift the circular plate 37 upward. The circular plate 37 drives the bottom pull rope 38 to be guided through the U-shaped guide wheel frame 39, and pulls the slide plate 42 to slide along the slide plate 40 and the second guide rod 41, so that the slide plate 42 drives the rectangular plate 4 4 and the rubber friction plate 47 slide in the direction of the cylinder 16, so as to automatically remove the cut armored cable 2 and automatically push the cut armored cable 2 to the outside of the sampling inspection table 1, without manual unloading, which is helpful to improve the sampling inspection efficiency of the cable. The cylinder 5 is started to restore the horizontal plate 8 to its initial position again. The slide plate 42 can automatically pull the draw rope 38 along the U-shaped guide wheel frame 39 to reset under the action of the third spring 43, and the circular plate 37 automatically resets downward; the through hole on the horizontal plate 8 can make the draw rope 38 slide up and down, and the draw rope 38 will not be moved downward when the cylinder 5 drives the cutter 6 and the horizontal plate 8 downward; the purpose of the baffle 46 is to limit the rectangular plate 44 to prevent the rectangular plate 44 from rotating upward.

[0053] The present invention also provides a charging pile cable armor sampling inspection method, which is performed by the following steps:

[0054] S1. When spot-checking the armored cable 2, the armored cable 2 is placed on the spot-checking table 1, one end of the armored cable 2 is inserted into the cylinder 16, and then the cylinder 5 is started to drive the cutter 6 and the horizontal plate 8 to move downward at the same time. The horizontal plate 8 drives the first tooth groove 11 on the driving plate 10 to move downward through the first L-shaped plate 9 and mesh with the large gear 13, so that the large gear 13 rotates;

[0055] S2. When the large gear 13 rotates, the driving rod 18 will slide along the arc-shaped sliding hole 14 on the surface of the large gear 13, and then the three driving rods 18 will simultaneously drive the sliding rod 17 to slide toward the inside of the cylinder 16, thereby driving the three clamping plates 19 to clamp the armored cable 2 at the same time, so as to achieve fixation between the random inspection and shearing of the armored cable 2. At the same time, after the top of the driving plate 10 is separated from the large gear 13, the cylinder 5 drives the cutter 6 to shear the armored cable 2, which helps to make the cable random inspection process more stable and prevent the armored cable 2 from bending more during shearing.

[0056] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
