DETAILED DESCRIPTION

[0034] 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.

[0035] 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.

[0036] Example 1: Reference Figure 1 - Fig.15, a cable automatic positioning and shearing device, comprising a support frame 1, a driving part 101 is fixedly installed on the top of the support frame 1, the driving part 101 is a hydraulic cylinder 1, the output end of the driving part 101 extends to the inner side of the support frame 1 and is connected to an articulated frame 2, a roller rangefinder 103 is installed at the bottom end of the articulated frame 2, a group of roller transmission components 102 are arranged on both sides of the support frame 1 for transmitting the cable, and a cutting device 9 is arranged on the right side of the roller transmission component 102 located on the right side of the support frame 1;

[0037] When in use, the control driving part 101 pushes the articulated frame 2 to drive the bottom end of the roller part of the roller distance meter 103 to contact the outer surface of the cable, and controls the two groups of roller transmission components 102 to drive the cable to be transmitted. The cable in transmission drives the roller part to rotate through the friction contact between the outer surface and the roller part of the roller distance meter 103, so as to measure the length of the transmitted cable. After measuring the length of the transmitted cable, when the set length is reached, the cutting device 9 is controlled to cut the cable;

[0038] Specifically, refer to Fig. 9 , the two groups of roller transmission components 102 each include a fixed frame 501, a transmission roller 502 is provided on both sides of the inner wall of the fixed frame 501, and both ends of each transmission roller 502 are fixedly connected to a rotating shaft 2 505, and the outer wall of the rotating shaft 2 505 is rotatably connected to the inside of the fixed frame 501, and the outer wall of the rotating shaft 2 505 at the bottom of the two transmission rollers 502 is fixedly connected to a gear 1 504, and the two gears 1 504 are meshed with each other. A driving motor 503 is fixedly installed at the lower inner side of the fixed frame 501, and the output end of the driving motor 503 is fixedly connected to one of the two gears 1 504. The driving motor 503 is controlled to drive one gear 1 504 to rotate, and the mutual meshing between the two gears 1 504 drives the other gear 1 504 to rotate in the opposite direction, thereby driving the two transmission rollers 502 to rotate relative to each other, and the cable between the two transmission rollers 502 is transmitted through the friction between the outer surfaces of the two transmission rollers 502 and the cable;

[0039] The articulated frame 2 in the above technical solution is a whole and cannot be folded.

[0040] Reference Fig.14 The cutting device 9 includes a mounting frame 901, a hydraulic cylinder 902 is fixedly installed on the top of the mounting frame 901, and a cutting knife 903 is connected to the output end of the hydraulic cylinder 902. The hydraulic cylinder 902 is controlled to push the cutting knife 903 down to cut the cable, thereby improving efficiency.

[0041] Example 2: Reference Fig.13Compared with the first embodiment, the difference is that the articulated frame 2 is set to be foldable. Considering that if the articulated frame 2 is not foldable, the control driving unit 101 pushes the articulated frame 2 to drive the bottom end of the roller part of the roller distance meter 103 to contact the outer surface of the cable, and there is a hard contact between them. Although theoretically it can barely maintain use, once the thrust of the driving unit 101 is too large, the roller distance meter 103 may press the cable down, causing the cable to bend, and it may also cause damage to the roller distance meter 103. Based on the above problem, the articulated frame 2 is set to be foldable and elastic;

[0042] Specific reference Fig.13 The articulated frame 2 includes a U-shaped frame 203, the top of the U-shaped frame 203 is fixedly connected to the output end of the driving unit 101, the inner wall of the U-shaped frame 203 is rotatably connected with a connecting frame 204 on both sides, the bottom of the connecting frame 204 is rotatably connected with a roller 201, the outer wall of the roller 201 is rotatably connected with a connecting frame 205 on both sides, the lower part of the connecting frame 205 is connected to the roller rangefinder 103, the inner middle part of the connecting frame 1 204 is fixedly connected with a transverse axis 1 206, the inner middle part of the connecting frame 205 is fixedly connected with a transverse axis 207, a thrust spring 1 202 is provided between the transverse axis 1 206 and the transverse axis 2 207, and the two ends of the thrust spring 1 202 are rotatably connected to the outer wall of the transverse axis 1 206 and the outer wall of the transverse axis 2 207 respectively, when the control driving unit 101 drives the articulated frame 2 to descend, the bottom end of the roller part of the roller rangefinder 103 is pushed to the cable When the outer surface contacts and the pressure continues to be applied downward, the middle part of the articulated frame 2, that is, the connection between the connecting frame 1 204 and the connecting frame 2 205, bends and folds, and a continuous downward force is applied to the roller distance meter 103 connected below the connecting frame 2 205 through the elastic force of the thrust spring 1 202, so that the roller part of the roller distance meter 103 is in closer contact with the outer surface of the cable. At the same time, the thrust spring 1 202 cooperates with the articulated frame 2, and no hard thrust is applied to the roller distance meter 103, which reduces the risk of damage to the roller distance meter 103 to a certain extent. At the same time, in order to prevent the roller distance meter 103 from being offset due to the folding of the articulated frame 2, a guide block 702 is fixedly installed at the outer bottom end of the articulated frame 2, and a vertical plate 7 is fixedly connected to the inner top of the support frame 1, and a slide groove 701 is provided below the vertical plate 7, and the inner wall of the slide groove 701 is slidably connected to the outer wall of the guide block 702;

[0043] In the above scheme, the distance between the two roller transmission components 102 is relatively fixed. When the cable is transmitted, the cable between the two roller transmission components 102 may have a weak surface tension due to some uncertain factors. In layman's terms, the length of the cable between the two roller transmission components 102 is greater than the distance between the two roller transmission components 102. When measured by the roller distance meter 103, the measured value will be inaccurate, affecting the use efficiency. Based on the above problem, Figure 1As shown, a support frame 3 is arranged outside the roller transmission assembly 102 located on the left side of the support frame 1 among the two roller transmission assemblies 102, and is slidably connected with the inner wall of the support frame 3, and is rotatably connected with a hinge rod 1 401 on the roller transmission assembly 102 located on the left side of the support frame 1, and the other end of the hinge rod 1 401 is rotatably connected with the outer wall of a roller shaft 1 201 of the articulated frame 2. When in use, the driving unit 101 pushes the articulated frame 2 to descend, and when the articulated frame 2 is folded, the middle part of the articulated frame 2, that is, the connection between the connecting frame 1 204 and the connecting frame 2 205, protrudes to the left side, and the articulated rod 1 401 is pushed by the roller shaft 1 201 to drive the roller transmission assembly 102 located on the left side of the support frame 1 to move outward along the inner wall of the support frame 3, so as to straighten the cable transmitted between the two roller transmission assemblies 102, increase the surface tension, and facilitate the subsequent roller distance meter 103 to measure the cable length;

[0044] Specifically, refer to Fig. 9 , Fig.10 ,lie in Figure 1 Side guide grooves 305 are provided on both sides of the outer wall of the fixed frame 501 of the roller transmission assembly 102 on the left side of the middle support frame 1, and bottom guide grooves 301 are provided on both sides of the bottom end of the upper fixed frame 501. Side guide rails 304 are fixedly installed on both sides of the inner wall of the support frame 3, and a bottom guide rail 302 is fixedly installed on the bottom. The outer wall of the bottom guide rail 302 is slidably connected to the inner wall of the bottom guide groove 301, and the inner wall of the side guide groove 305 is slidably connected to the outer wall of the side guide rail 304. Both sides of the bottom end of the fixed frame 501 are rotatably connected to moving wheels 303, and the outer wall of the moving wheel 303 is rollingly connected to the bottom end of the inner wall of the support frame 3. When in use, the articulated frame 2 is folded and the roller 201 drives the articulated rod 401 to push the articulated rod 401 located at Figure 1 The moving wheel 303 below the fixed frame 501 of the roller transmission assembly 102 on the left side of the middle support frame 1 rolls along the inner wall of the support frame 3, and the movement of the fixed frame 501 is guided and limited by the cooperation between the side guide rail 304 and the bottom guide rail 302 and the side guide groove 305 and the bottom guide groove 301;

[0045] In the above scheme, the roller transmission assembly 102 pushes the cable to move by friction between the two relatively rotating transmission rollers 502 and the cable. When in use, the outer surface of the transmission roller 502 is required to be relatively strict. If there are burrs on the surface of the transmission roller 502 during use, the surface of the transmitted cable will be scratched. At the same time, the friction transmission between the transmission roller 502 and the cable will cause invalid transmission if the cable diameter is smaller than the distance between the two transmission rollers 502. If the diameter of the cable is too large, it may cause certain wear on the cable surface. In order to solve the above problem, reference is made to Fig.10 - Fig.13, a rubber air sleeve 601 is installed on the outer wall of the driving roller 502, and an air cylinder 606 is installed between the horizontal axis 1 206 and the horizontal axis 2 207 of the articulated frame 2, and the vent hole 610 of the air cylinder 606 is connected and communicated with the rubber air sleeve 601 through a transmission component, and the driving part 101 pushes the articulated frame 2 to descend and fold, and the air cylinder 606 is compressed during folding, and the gas in the air cylinder 606 is transmitted to the rubber air sleeve 601 through the vent hole 610 and the transmission component, so that the rubber air sleeve 601 swells and wraps the cable, increasing the contact area with the cable, and at the same time, there is a certain buffer space between the elastic rubber air sleeve 601 after inflation and the cable, reducing the risk of damage to the cable due to hard friction;

[0046] Specific references Fig.10 - Fig.13 The air cylinder 606 includes a jacket 607, the inner wall of the jacket 607 is slidably connected to a piston 608, the bottom end of the piston 608 is fixedly connected to an inner rod 609, the bottom end of the inner rod 609 is rotatably connected to the outer wall of the second horizontal axis 207, the top of the jacket 607 is rotatably connected to the outer wall of the first horizontal axis 206, and both sides of the upper outer wall of the jacket 607 are provided with vents 610, the transmission component includes a transmission pipe 605, the transmission pipe 605 is connected to the outer side of the vent 610, and the inner side of the transmission roller 502 is provided with a transmission groove 602, such as Fig.11 As shown, one end of the transmission groove 602 is connected to the internal space of the rubber air sleeve 601, and the other end passes through the rotating shaft 2505 at the top, and the inner wall is rotatably connected to the connecting pipe 604 through a sealed bearing, and the outer wall of the connecting pipe 604 is fixedly connected to the bracket 603, and the bottom end of the bracket 603 is fixedly connected to the top of the support frame 3, and the top of the connecting pipe 604 is connected to the end of the transmission pipe 605 away from the vent 610. When in use, the articulated frame 2 is folded to squeeze the air cylinder 606, and the gas is introduced into the rubber air sleeve 601 through the transmission pipe 605, the connecting pipe 604 and the transmission groove 602, so that the rubber air sleeve 601 bulges to wrap the cable.

[0047] In the above solution, after the cable is cut by the cutting device 9, the cable is divided into two parts, which are respectively located on both sides of the cutting blade 903 of the cutting device 9. Figure 1 , the cable cut off on the right side is wound up, and the cable end for subsequent transmission is located on the left side of the cutting knife 903. When the cable is wound up, it is necessary to manually pull the cable from the left side of the mounting frame 901 to the right side, which increases the safety risk and consumes manpower. Based on the above problem, two limiting sleeves 802 are provided on the right side of the support frame 1. The two limiting sleeves 802 are respectively located on both sides of the cable, such as Figure 8As shown, the outer side of the limiting sleeve 802 is rotatably connected to the moving frame 801, and the outer side of the moving frame 801 is rotatably connected to the hinge rod 2 402, and the other end of the hinge rod 2 402 is rotatably connected to the outer wall of the roller 201 of the hinge frame 2. After the cutting is completed, the control driving part 101 drives the hinge frame 2 to rise, and the reset thrust of the thrust spring 202 causes the middle rotation connection of the hinge frame 2 to move toward the side close to the cutting device 9. At this time, the movement of the roller 201 will push the moving frame 801 to move to the right through the hinge rod 2 402, and the right end of the limiting sleeve 802 on the inner side of the moving frame 801 will tilt and rotate inward and press against the outer wall of the cable. After pressing, the cable is pushed to move to the right through the cutting device 9 with the reset thrust of the thrust spring 202. When the limiting sleeve 802 presses against the outer wall of the cable, the gas in the rubber air sleeve 601 is extracted with the extension of the air cylinder 606 to relieve the restriction on the cable and facilitate the subsequent pushing of the cable.

[0048] Specific references Figure 6 , Figure 7 , Figure 8 , Fig.15 , guide frames 805 are fixedly installed at both ends of the right side of the support frame 1, and the outer wall of the guide frame 805 is slidably connected to the moving frame 801, the outer side of the moving frame 801 is rotatably connected to the hinge rod 2 402, and the inner side of the moving frame 801 is rotatably connected to the limiting sleeve 802, the top of the hinge rod 2 402 is rotatably connected to the outer wall of the roller 1 201, and the inside of the moving frame 801 is slidably connected to the outer wall of the guide frame 805, and the inner right end of the moving frame 801 is fixedly installed with a thrust spring 2 803, and the end of the thrust spring 2 803 away from the moving frame 801 is connected to the outer side of the limiting sleeve 802. The guide frame 805 is connected to the side, and a conical sleeve 804 is fixedly installed on the left side of the outer wall of the guide frame 805. The diameter of the conical sleeve 804 increases from left to right. When the articulated frame 2 is folded and contracted, the roller 1 201 pulls the movable frame 801 to move to the left along the guide frame 805 through the articulated rod 2 402, driving the limiting sleeve 802 to move to the left, passing through the inner wall of the conical sleeve 804. Because the inner diameter of the conical sleeve 804 decreases from right to left, the limiting sleeve 802 will take the rotation connection between it and the movable frame 801 as the center of the circle, and the right end will open outward and separate from the cable, such as Figure 8 As shown in the figure, when the articulated frame 2 is extended by the restoring elastic force of the thrust spring 1 202, the roller 1 201 pushes the movable frame 801 to move to the right along the guide frame 805 through the articulated rod 2 402, driving the limiting sleeve 802 to move to the right. Because the diameter of the conical sleeve 804 increases from left to right, the restriction on the limiting sleeve 802 will be gradually reduced. Under the influence of the thrust spring 2 803, the right end of the limiting sleeve 802 rotates toward the end close to the cable, gradually conflicts with the outer wall of the cable, so that the limiting sleeves 802 on both sides form a clamping state for the cable. Fig.15As shown, as the articulated frame 2 continues to extend, the articulated rod 402 will continue to push the movable frame 801 to move, thereby driving the limiting sleeve 802 to push the cable to the right one section, so that the cross-section of the cable passes through the cutting device 9, which is convenient for subsequent transmission or winding. This section that is advanced forward can be connected to the subsequent transmission roller or to the winding reel.
