Description

Technical Field

[0001] The invention relates to the technical field of strength testing, and in particular to a cable fixing tube positioning and processing device for electric power equipment. Background Art

[0002] In power equipment, there are many cables and the span is relatively large. In order to organize, protect, guide, and fix the cables, a cable fixing sleeve is installed outside multiple cables and then the sleeve is fixed.

[0003] Since the fixed tube is relatively long during production and the cables of different power equipment have different lengths, the fixed tube needs to be cut.

[0004] In traditional technology, such as Figure 1 As shown, the cutting of the fixed pipe is achieved by using the cutting knife at the top and the two rotating driving wheels at the bottom. The specific principle is: the fixed pipe is placed above the middle of the two rotating driving wheels, and then the lifter is used to drive the cutting knife to descend to contact the fixed pipe and maintain a certain cutting pressure, and then the rotating driving wheel is used to drive the fixed pipe to rotate, and the cutting force generated by the relative rolling rotation of the fixed pipe and the cutting wheel is used to achieve circular cutting.

[0005] The prior art has the following disadvantages: when the length of the fixed pipe is long, if the fixed pipe is rotated at high speed for cutting, there are certain safety hazards. Summary of the invention

[0006] The purpose of the present invention is to solve the shortcomings in the prior art and to propose a positioning and processing device for a cable fixing tube of an electric power equipment.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A cable fixing pipe positioning and processing device for electric power equipment, comprising a ring frame,

[0009] The ring frame is supported and fixed on the ground by supporting legs, the inner side of the ring frame is rotatably connected with a rotating ring, the side wall of the rotating ring is provided with at least three groups of cutting arm assemblies arranged at equal angles along the radial direction, and the outer periphery of the rotating ring is provided with a centering drive assembly for driving the cutting arm assembly;

[0010] One side of the rotating ring is connected to a gear ring, a motor is fixed to the side wall of the ring frame by bolts, an output shaft of the motor is connected to a gear by a key, and the gear is meshed with the outer wall of the gear ring;

[0011] The cutting arm assembly includes a cylinder body 1 slidably connected to a rotating ring and a piston 1 slidably connected to the inner wall of the cylinder body 1, a piston rod 1 is fixed to the other side wall of the piston 1, and the other end of the piston rod 1 is rotatably connected to a cutting knife via a knife shaft, a spring 1 is buckled on the outer wall of the piston 1, and the other end of the spring 1 is buckled on the inner wall of the cylinder body 1.

[0012] Preferably: limiting wheels are provided at both ends of the knife shaft.

[0013] Furthermore: the centering drive assembly includes a connecting rod rotatably connected to the top of the cutting arm assembly and a driving rod rotatably connected to the other end of the connecting rod, the driving rod is slidably connected to the inner wall of the rotating ring, and the outer wall of the ring frame is fixed with a telescope by bolts, the telescopic end of the telescope is fixed to the limit plate by bolts, and the end of the driving rod is matched with the side wall of the limit plate by ball rolling.

[0014] On the basis of the above-mentioned solution: the outer wall of the cylinder body one is buckled with a spring three, and the other end of the spring three is buckled with the inner wall of the rotating ring.

[0015] A more preferred solution in the aforementioned solution is that the gear ring is rotatably connected to the outer wall of the rotating ring.

[0016] As a further solution of the present invention: a plurality of transmission grooves are formed on the end face of the gear ring, a cylinder body 2 is fixed to the inner wall of the rotating ring, a piston 2 is slidably connected to the inner wall of the cylinder body 2, and an insertion rod that engages with the transmission groove is fixed to one side of the piston 2.

[0017] At the same time, a connecting pipe is fixed to the end face of the rotating ring, one side of the connecting pipe is connected to the rodless chamber of cylinder body one through a hose, and the other side of the connecting pipe is connected to the rodless chamber of cylinder body two through a connecting pipe.

[0018] As a preferred embodiment of the present invention: a bracket is fixedly connected to the side wall of the ring frame, and two "V" groove rollers distributed upward and downward are arranged on the inner side of the bracket.

[0019] At the same time, the two ends of the "V" groove roller are rotatably connected to a slider through a roller shaft, and the bracket is slidably connected to the outer wall of the slider through a slide groove opened on its inner wall, and the side wall of the slider is buckled with a spring 2, and the other end of the spring 2 is buckled to the inner wall of the slide groove.

[0020] As a more optimal solution of the present invention: the "V" groove roller is made of rubber.

[0021] The beneficial effects of the present invention are:

[0022] 1. The present invention provides a peripheral wrapping structure. During the cutting process, the cutting blade is a rotating part and the fixed tube is a fixed part. Thus, a relatively long fixed tube is also in a stationary state during cutting, thereby increasing safety.

[0023] 2. The present invention, by setting at least three groups of cutting arm assemblies arranged at equal angles, utilizes the limiting plate to limit the driving rod to realize the extension and retraction of multiple cutting arm assemblies, so that the multiple cutting arm assemblies can move the same distance, so that the contact pressure of each cutting knife on the fixed tube is the same, and the contact pressures of multiple groups of cutting knives offset each other, so that the resultant force on the fixed tube is almost zero, thereby preventing the cantilever end of the fixed tube from being deformed by bending moment.

[0024] 3. The present invention realizes the telescopic drive of the cutting arm assembly by limiting the driving rod through the limit plate, and the movement of the limit plate is derived from the telescopic device. The telescopic device is fixed to the side wall of the rotating ring, so that the rotating ring can rotate while the telescopic device is fixed, thereby preventing the wiring harness from being entangled and increasing safety.

[0025] 4. The present invention, by setting a transmission groove and an insertion rod, combines the principle of pneumatic drive, so that the rotating ring can be driven to rotate only and only when all the cutting knives are reliably in contact with the closure and generate a certain pressure. On the one hand, it prevents the safety hazard of high-speed rotation of the rotating ring in a non-working state, and on the other hand, it also prevents the production of defective products due to unpreparedness.

DETAILED DESCRIPTION

[0035] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0036] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0037] Embodiment 1:

[0038] A cable fixing pipe positioning and processing device for power equipment, such as Figure 2-Figure 8 As shown, it includes a ring frame 2, which is supported and fixed to the ground by supporting legs 1. The inner side of the ring frame 2 is rotatably connected to a rotating ring 3, and the side wall of the rotating ring 3 is provided with at least three groups of cutting arm assemblies 5 arranged at equal angles along the radial direction, and the periphery of the rotating ring 3 is provided with a centering drive assembly 4 for driving the cutting arm assembly 5.

[0039] One side of the rotating ring 3 is connected to a gear ring 7 in transmission, a motor 8 is fixed to the side wall of the ring frame 2 by bolts, an output shaft of the motor 8 is connected to a gear 6 by a key, and the gear 6 is meshed with the outer wall of the gear ring 7 .

[0040] The cutting arm assembly 5 includes a cylinder body 13 slidably connected to the rotating ring 3 and a piston 15 slidably connected to the inner wall of the cylinder body 13. A piston rod 16 is fixed to the other side wall of the piston 15. The other end of the piston rod 16 is rotatably connected to a cutting knife 17 via a knife shaft 19. A spring 14 is buckled on the outer wall of the piston 15. The other end of the spring 14 is buckled on the inner wall of the cylinder body 13.

[0041] The two ends of the knife shaft 19 are provided with limiting wheels 18, which can contact the tube wall to limit the rebound position of the piston 15 when cutting, so as to prevent the tube wall from being scratched by the contact between the piston rod 16.

[0042] When the device is in use, the fixed tube can be transported by a corresponding transport device. After reaching the cutting length, the rotating ring 3 is used to drive multiple cutting arm assemblies 5 to move inward at the same time until the cutting knife 17 contacts the outer wall of the fixed tube. The drive movement is continued to compress the spring 14 to generate pressure. Then the motor 8 is started. The motor 8 drives the gear 6 to rotate, thereby driving the gear ring 7 and the rotating ring 3 to rotate through meshing action, so that the multiple cutting arm assemblies 5 rotate relative to the fixed tube. During the rotation, the elastic force of the compressed spring 14 is used for cutting.

[0043] The device is provided with an outer wrapping structure. During the cutting process, the cutting blade 17 is a rotating part and the fixed tube is a fixed part. Thus, a relatively long fixed tube is kept in a stationary state during cutting, thereby increasing safety.

[0044] In order to solve the deformation problem; Figure 4 As shown, the centering drive assembly 4 includes a connecting rod 12 rotatably connected to the top of the cutting arm assembly 5 and a driving rod 11 rotatably connected to the other end of the connecting rod 12, the driving rod 11 is slidably connected to the inner wall of the rotating ring 3, and the outer wall of the ring frame 2 is fixed with a telescope 10 by bolts, the telescopic end of the telescope 10 is fixed with a limit plate 9 by bolts, the end of the driving rod 11 is matched with the side wall of the limit plate 9 by ball rolling, the outer wall of the cylinder body 13 is buckled with a spring three 33, and the other end of the spring three 33 is buckled to the inner wall of the rotating ring 3.

[0045] When the telescopic device 10 is extended, it can drive the limit plate 9 to move axially, thereby limiting the driving rod 11 so that the driving rod 11 moves axially, thereby causing the connecting rod 12 to rotate and drive the cutting arm assembly 5 to move inward. When the telescopic device 10 is retracted, the cutting arm assembly 5 is reset by the pulling force of the spring three 33.

[0046] The device, by providing at least three groups of cutting arm assemblies 5 arranged at equal angles, utilizes the limiting plate 9 to limit the driving rod 11 to realize the extension and retraction of multiple cutting arm assemblies 5, so that the multiple cutting arm assemblies 5 can move the same distance, so that the contact pressure of each cutting knife 17 on the fixed pipe is the same, and the contact pressures of multiple groups of cutting knives 17 offset each other, so that the resultant force on the fixed pipe is almost zero, thereby preventing the cantilever end of the fixed pipe from being deformed by bending moment.

[0047] In addition, the device limits the driving rod 11 through the limit plate 9 to realize the telescopic drive of the cutting arm assembly 5, and the movement of the limit plate 9 is derived from the telescopic movement of the telescope 10. The telescope 10 is fixed to the side wall of the rotating ring 3, so that the telescope 10 can be fixed while the rotating ring 3 rotates, preventing the wiring harness from being entangled and increasing safety.

[0048] To solve security issues; Figure 6 As shown, the gear ring 7 is rotatably connected to the outer wall of the rotating ring 3, and a plurality of transmission grooves 20 are opened on the end face of the gear ring 7, a cylinder body 23 is fixed to the inner wall of the rotating ring 3, a piston 22 is slidably connected to the inner wall of the cylinder body 23, and an insert rod 21 that engages with the transmission groove 20 is fixed to one side of the piston 22.

[0049] A connecting pipe 25 is fixed to the end surface of the rotating ring 3 , one side of the connecting pipe 25 is connected to the rodless cavity of the cylinder body 13 through a hose 24 , and the other side of the connecting pipe 25 is connected to the rodless cavity of the cylinder body 23 through a connecting pipe 26 .

[0050] When the cutting blade 17 is reliably in contact with the tube wall and generates a certain pressure, the piston 15 is displaced and the spring 14 is compressed, the pressure of the rodless chamber of the cylinder body 13 increases, and the pressure is transmitted to the cylinder body 23 through the connecting pipe 25, so that the piston 22 moves. The transmission groove 20 is engaged with the plug rod 21, and the gear ring 7 is locked with the rotating ring 3. At this time, the rotating ring 3 can be driven by the rotating ring 3. When some or all of the cutting blades 17 are not reliably in contact with the closure and generate a certain pressure, the fluid entering the cylinder body 23 is not enough to drive the piston 22 to move to the matching state of the plug rod 21 and the transmission groove 20, so that the gear ring 7 is connected to the rotating ring 3 for relative rotation, and the gear ring 7 cannot drive the rotating ring 3.

[0051] The device, by providing the transmission groove 20 and the insertion rod 21, combines the principle of pneumatic drive, so that the rotating ring 3 can be driven to rotate only when all the cutting knives 17 are reliably in contact with the closure and generate a certain pressure. On the one hand, it prevents the safety hazard of high-speed rotation of the rotating ring 3 in the non-working state, and on the other hand, it also prevents the production of defective products due to unpreparedness.

[0052] When the present embodiment is in use, the fixed tube can be transported by a corresponding conveying device. When the cutting length is reached, the telescopic device 10 is extended, which can drive the limit plate 9 to move axially, thereby limiting the driving rod 11 so that the driving rod 11 moves axially, thereby causing the connecting rod 12 to rotate and drive the cutting arm assembly 5 to move inward until the cutting knife 17 contacts the outer wall of the fixed tube, and then continues to drive the movement so that the spring 14 is compressed and pressure is generated. When the cutting knife 17 contacts the tube wall reliably and generates a certain pressure, the piston 15 is displaced and the spring 14 is compressed, and the pressure in the rodless chamber of the cylinder body 13 increases. The pressure is transmitted to the cylinder body 23 through the connecting pipe 25, thereby causing the piston 22 to move. The transmission groove 20 is engaged with the insertion rod 21, and the ring gear 7 is locked with the rotating ring 3. At this time, the rotating ring 3 can be driven by the rotating ring 3, and then the motor 8 is started. The motor 8 drives the gear 6 to rotate, thereby driving the ring gear 7 and the rotating ring 3 to rotate through the meshing action, so that the multiple cutting arm assemblies 5 rotate relative to the fixed tube. During the rotation process, the cutting is performed using the compressed elastic force of the spring 14.

[0053] Embodiment 2:

[0054] A cable fixing pipe positioning and processing device for power equipment, such as Figure 8 As shown, in order to solve the stability problem, this embodiment makes the following improvements on the basis of embodiment 1: the side wall of the ring frame 2 is fixedly connected with a bracket 27, and the inner side of the bracket 27 is provided with two "V" groove rollers 29 distributed upper and lower.

[0055] The two ends of the "V" groove roller 29 are rotatably connected to the slider 31 through the roller shaft 30, and the bracket 27 is slidably connected to the outer wall of the slider 31 through the slide groove 32 provided on its inner wall, and the side wall of the slider 31 is buckled with a spring 28, and the other end of the spring 28 is buckled to the inner wall of the slide groove 32.

[0056] The “V” groove roller 29 is made of rubber with a high friction coefficient.

[0057] When this embodiment is in use, the fixed pipe can be passed through two "V" groove rollers 29, and the two "V" groove rollers 29 hold the fixed pipe through the pressure generated by the spring 28, thereby preventing rotation.

[0058] 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.
