Description

Technical Field

[0001] The invention relates to the technical field of power transmission line construction tools, in particular to integrated equipment for bending and cutting grounding round steel of power transmission lines. Background Art

[0002] At present, the grounding round steel of the transmission line is an important grounding device, which is directly related to the safe and stable operation of the power system. At the construction and fault elimination and reconstruction site of the transmission line, the grounding round steel needs to be cut and bent into a certain angle. With the continuous improvement of the power industry's requirements for construction quality and efficiency, there is an urgent need for equipment that can efficiently and accurately complete the cutting and bending of the grounding round steel of the transmission line.

[0003] The existing split hydraulic bending machine consists of a hydraulic pump and a set of 90-degree bending molds. It is relatively bulky, cannot adjust the angle, and requires a 220V power supply. For the construction of power transmission lines in wild mountainous areas, there is no power supply, and a more bulky generator must be carried. The above equipment must be carried up the mountain by manpower. Although the existing portable bending machine has reduced the weight and integrated lithium batteries, it cannot accurately control the bending angle of the grounded round steel. In addition, traditional grounded round steel processing usually requires two devices to perform cutting and bending operations separately, which not only increases the equipment cost and occupied space, but also reduces processing efficiency.

[0004] In summary, the existing technical solutions have the problems of low processing efficiency, unadjustable bending angle, poor precision, high labor intensity, etc. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the existing defects and provide an integrated device for bending and cutting grounding round steel for transmission lines. The two functions of bending and cutting are integrated in a portable machine. The equipment has low cost, occupies a small space, is easy to carry, can reduce the labor intensity of power construction personnel, has high processing efficiency for grounding round steel for transmission lines, is convenient for precise control of the bending angle of the grounding round steel for transmission lines, has high bending accuracy, and can effectively solve the problems in the background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: an integrated device for bending and cutting round steel for grounding of power transmission lines, comprising a device power body, the device power body comprising a housing and a hydraulic actuator, the housing having a hydraulic actuator installed therein, and further comprising:

[0007] The integrated head mechanism includes a working cover, the front bottom of the shell is fixedly connected to the rear end of the base, the upper side of the base is fixedly mounted with the working cover, the telescopic end of the front side of the hydraulic actuator passes through the through hole in the middle of the working cover, the working cover is divided into an upper equipment chamber and a lower working chamber by a partition, and two round steel insertion grooves are respectively provided on both sides of the working cover corresponding to the left and right ends of the working chamber;

[0008] The bending angle control mechanism is installed in the working cover;

[0009] The bending and cutting switching mechanism is installed on the front top of the base.

[0010] The partition divides the working cover into two chambers, wherein the equipment chamber is used to install the main body of the bending angle control mechanism, and the bending and cutting switching mechanism is used to control whether the equipment performs cutting or bending functions, wherein the bending angle control mechanism is not required to function when the equipment performs cutting functions.

[0011] When it is necessary to cut the grounding round steel of the transmission line, the cutting end of the bending and cutting switching mechanism is facing backwards, the grounding round steel of the transmission line is passed through between the two round steel insertion grooves, and the grounding round steel of the transmission line is placed at the front end of the two round steel insertion grooves. The telescopic end on the front side of the hydraulic actuator extends forward, pushing the grounding round steel of the transmission line gradually close to the cutting end of the bending and cutting switching mechanism until the grounding round steel of the transmission line is cut off.

[0012] When it is necessary to bend the transmission line grounding round steel, the bending end of the bending and cutting switching mechanism is directed backwards, the transmission line grounding round steel is passed through between the two round steel insertion grooves, and the transmission line grounding round steel is placed at the front end of the two round steel insertion grooves. The telescopic end on the front side of the hydraulic actuator extends forward to push the transmission line grounding round steel to gradually bend forward. The bending angle control mechanism blocks the front sides of both ends of the transmission line grounding round steel, thereby controlling the bending angle of the transmission line grounding round steel. The telescopic end on the front side of the hydraulic actuator stops after extending forward a specific distance, completing the bending of the transmission line grounding round steel.

[0013] Furthermore, the bending angle control mechanism includes a bending column, an annular limit groove and an opposite movement control component. Two vertical bending columns are respectively provided on the left and right sides of the front end of the working chamber. The two bending columns are connected to the opposite movement control component, and an annular limit groove is respectively provided in the middle of each bending column. In the initial stage, the opposite movement control component drives the two bending columns to move away from each other synchronously. When preparing to bend the grounding round steel of the transmission line, the opposite movement control component synchronously drives the two bending columns to move closer to each other until the two bending columns are at a specific distance. At this time, the two bending columns and the bending ends of the bending and cutting switching mechanism form a triangle. The angle at the front end of the triangle is the preset bending angle of the grounding round steel of the transmission line. The telescopic end on the front side of the hydraulic actuator extends forward a specific distance, so that the distance between the two bending columns is different, and the bending angle of the grounding round steel of the transmission line is also different, so that the control of the bending angle of the grounding round steel of the transmission line can be completed. The transmission line grounding round steel is pushed forward by the telescopic end on the front side of the hydraulic actuator, the transmission line grounding round steel is blocked by two bending columns, the transmission line grounding round steel begins to be bent, and the telescopic end on the front side of the hydraulic actuator extends forward a specific distance and then stops, thus completing the bending of the transmission line grounding round steel. The setting of the annular limit groove can limit the transmission line grounding round steel, so that the position of the transmission line grounding round steel is kept stable when the bending column contacts the transmission line grounding round steel, avoiding the transmission line grounding round steel from shifting relative to the bending column during the bending process, which is beneficial to improving the bending accuracy of the transmission line grounding round steel.

[0014] Furthermore, the opposite movement control component includes a slide groove, a slider, a connecting rod, a movable shaft, a ratchet turntable and a control motor. The upper and lower ends of each bending column are respectively fixedly connected to two sliders. The upper and lower sides of the working cavity are respectively provided with slide grooves connected to the sliders for transverse sliding. A control motor is installed on the top of the equipment cavity. The output shaft at the bottom of the control motor is fixedly connected to the middle part of the ratchet turntable. Two movable shafts symmetrical about the center of the ratchet turntable are installed on the ratchet turntable. The two movable shafts are respectively rotatably connected to one end of the two connecting rods, and the other ends of the two connecting rods are respectively movably connected to the sliders on the top of the two bending columns. The ratchet turntable, two movable shafts and two connecting rods constitute two groups of structures similar to crank-connecting rods. The control motor drives the ratchet turntable to rotate counterclockwise, and the ratchet turntable pushes the sliders on the top of the two bending columns away from each other along their respective slide grooves through the two connecting rods, thereby driving the two bending columns to move away from each other synchronously. The control motor drives the ratchet turntable to rotate clockwise, and the ratchet turntable pulls the sliders on the top of the two bending columns along their respective slide grooves towards each other through the two connecting rods, thereby driving the two bending columns to move towards each other synchronously.

[0015] The distances between the two bending columns are different. When the telescopic end on the front side of the hydraulic actuator extends forward by a specific distance, the grounding round steel of the transmission line is bent at different angles. The distances between the two bending columns are divided into eleven levels, and the grounding round steel of the transmission line is bent into 11 levels of 30°, 34°, 40°, 50°, 60°, 70°, 80°, 90°, 100°, 110°, and 120°.

[0016] Furthermore, the bending angle control mechanism further includes a rotating shaft, a safety knob, and a brake claw. The rotating shaft is rotatably connected in the equipment cavity. The top of the rotating shaft extends to the upper side of the working cover and is fixedly connected with the safety knob. The bottom end of the rotating shaft is fixedly connected with a brake claw that cooperates with the outer peripheral side of the ratchet turntable. After the control motor works to control the distance between the two bending columns to be a specific value, the rotating shaft is rotated through the safety knob, and the rotating shaft drives the brake claw to rotate, so that the brake claw is engaged with the ratchet teeth on the outer side of the ratchet turntable to complete the locking of the ratchet turntable, avoiding the rotation of the ratchet turntable caused by the force on the bending column at the bending part, preventing the control motor from reversing when the bending column is stressed, which is beneficial to improving the bending accuracy and protecting the control motor.

[0017] Furthermore, the bending angle control mechanism further includes an oil discharge valve and an oil circuit. The oil discharge valve is installed at the top of the equipment cavity. The oil discharge valve is connected to the rotating shaft, and the oil discharge valve is connected to the hydraulic actuator through the oil circuit.

[0018] After the bending is completed, the safety knob is rotated in the reverse direction. The safety knob opens the oil discharge valve through the rotating shaft. The oil discharge valve allows the hydraulic oil in the hydraulic actuator to be depressurized through the oil circuit, and the telescopic end of the hydraulic actuator cannot be pushed forward, preventing operation errors. Only when the safety knob and the rotating shaft drive the brake claw to engage with the ratchet turntable, the oil discharge valve is closed, and the telescopic end of the hydraulic actuator can extend forward. At this time, bending and cutting can be carried out, improving the safety performance;

[0019] When the oil discharge valve is opened, the rotating shaft also drives the brake claw to disengage from the ratchet turntable, and then the control motor is used to control the two bending columns to move away from each other. At this time, it is convenient to take away the bent grounding round steel of the transmission line.

[0020] Furthermore, the bending and cutting switching mechanism includes a round seat, a cutting edge, a bending head, an arc groove, and a switching control component. The top of the front end of the base is connected to the bottom of the round seat through the switching control component. A cutting edge is arranged on one side of the round seat, and a bending head is arranged at the other end of the round seat. An arc groove is opened at the end of the bending head.

[0021] The switching control component is used to drive the round seat to rotate and lock the position of the round seat at the same time. The cutting blade serves as the cutting end of the bending and cutting switching mechanism. When cutting the transmission line grounding round steel, the cutting blade needs to face backward. The bending head serves as the bending end of the bending and cutting switching mechanism. When bending the transmission line grounding round steel, the bending head needs to face backward. When the bending part of the transmission line grounding round steel is close to the bending head, the arc groove can limit the bending part of the transmission line grounding round steel, which is beneficial to maintain the stability of the transmission line grounding round steel.

[0022] Furthermore, the switching control assembly includes a vertical cylinder, a fastening bolt, a switching shaft, a rotating disk, a limit strip and a compression spring. A circular blind hole is provided at the top front end of the base, and a limit strip groove is provided at the bottom of the circular blind hole. The vertical cylinder is fixedly connected to the circular blind hole by a fastening bolt, a switching shaft is vertically inserted through the top center of the vertical cylinder, and the bottom end of the switching shaft is fixedly connected to the rotating disk. A limit strip that cooperates with the limit strip groove is provided at the bottom of the rotating disk, and a compression spring is sleeved on the part of the switching shaft located in the vertical cylinder. When the limit card strip is engaged with the limit bar slot, the cutting blade and the bending head are both distributed longitudinally, and the front and rear directions of the cutting blade and the bending head need to be switched, the round seat is lifted upward, driving the switching shaft and the rotating disk to move upward relative to the vertical cylinder. At this time, the compression spring is compressed, and the limit card strip is disengaged from the limit bar slot, the round seat is rotated 180°, the round seat is released, the compression spring resets and extends, and the switching shaft and the rotating disk are pushed downward relative to the vertical cylinder again, and the limit card strip is re-engaged with the limit bar slot. At this time, the position of the round seat is re-locked, and the front and rear positions of the cutting blade and the bending head are swapped, thereby allowing the cutting blade to face backwards or the bending head to face backwards.

[0023] Furthermore, it also includes a round steel bending and cutting pushing mechanism, which includes a disassembly seat, a rotating shaft, a pushing block and a locking assembly. The telescopic end on the front side of the hydraulic actuator is detachably installed with a disassembly seat, and a pushing block is rotatably connected to the disassembly seat through a vertical rotating shaft. One end of the pushing block is arranged in an arc shape, and the other end of the pushing block is arranged in an isosceles trapezoidal structure. The pushing block is connected to the disassembly seat through a locking assembly.

[0024] When bending the transmission line grounding round steel, if it is necessary to make the bending part of the transmission line grounding round steel into an arc shape, the pushing block is rotated relative to the disassembly seat through the rotating shaft, so that the arc-shaped end of the pushing block faces forward, and the locking assembly locks the disassembly seat and the pushing block. If it is necessary to make the bending part of the transmission line grounding round steel have a more obvious bending angle, the end of the pushing block with an isosceles trapezoidal structure faces forward, and then the locking assembly locks the disassembly seat and the pushing block, wherein the distance between the two ends of the pushing block and the center of the rotating shaft is the same, no matter which end faces forward, the pushing distance of the transmission line grounding round steel is consistent.

[0025] When cutting the grounding round steel of the power transmission line, the cutting effect will not be affected if either end of the push block is facing forward.

[0026] Furthermore, the integrated head mechanism also includes a triangular groove and a displacement sensor. The bottom of the working cover is provided with a triangular groove, and the rear end of the triangular groove is provided with a displacement sensor. The triangular groove is used to install the displacement sensor, and the displacement sensor is used to detect the distance that the telescopic end on the front side of the hydraulic actuator moves forward.

[0027] Furthermore, it also includes a bending and cutting length control mechanism, which includes a sliding sleeve, a sliding bar, a control baffle and a butterfly bolt. The sliding sleeve is fixedly connected to the bottom side of the working cover at a position corresponding to the front end of the round steel insertion groove, and the sliding bar is horizontally slidably connected in the sliding sleeve. The control baffle is fixedly connected to the upper side of the end of the sliding bar away from the working cover, and the butterfly bolt is threadedly connected to the bottom of the sliding sleeve, and the butterfly bolt presses against the sliding bar. The control baffle is set corresponding to the end of the transmission line grounding round steel to be bent. Loosening the butterfly bolt can allow the slide bar to slide along the sliding sleeve, thereby changing the distance between the control baffle and the push block, thereby changing the bending or cutting position of the transmission line grounding round steel. Tightening the butterfly bolt locks the position of the slide bar and the control baffle. Each time thereafter, the transmission line grounding round steel is passed through the front side of the two round steel insertion grooves, and then the end of the transmission line grounding round steel close to the control baffle is made to rest against the side of the control baffle close to the working cover, which is convenient for controlling the bending or cutting position of the transmission line grounding round steel, and is beneficial for repeatedly bending or cutting the same transmission line grounding round steel.

[0028] Compared with the prior art, the integrated equipment for bending and cutting round steel for transmission line grounding has the following beneficial effects:

[0029] 1. When it is necessary to cut the grounding round steel of the transmission line, turn the cutting end of the bending and cutting switching mechanism toward the rear, pass the grounding round steel of the transmission line through the two round steel insertion grooves, and let the grounding round steel of the transmission line be at the front end of the two round steel insertion grooves. The telescopic end on the front side of the hydraulic actuator extends forward, pushing the grounding round steel of the transmission line gradually close to the cutting end of the bending and cutting switching mechanism until the grounding round steel of the transmission line is cut off, and the cutting work of the grounding round steel of the transmission line is completed.

[0030] 2. When preparing to bend the grounding round steel of the transmission line, the bending end of the bending and cutting switching mechanism faces backward, and the moving control component drives the two bending columns to approach each other synchronously until the two bending columns are at a specific distance. At this time, the two bending columns and the bending end of the bending and cutting switching mechanism form a triangle, and the angle at the front end of this triangle is the preset angle for bending the grounding round steel of the transmission line. The telescopic end on the front side of the hydraulic actuator extends forward by a specific distance, so that the distance between the two bending columns is different, and the bending angle of the grounding round steel of the transmission line is also different, enabling the control of the bending angle of the grounding round steel of the transmission line. The grounding round steel of the transmission line is pushed forward by the telescopic end on the front side of the hydraulic actuator, blocked by the two bending columns, and the grounding round steel of the transmission line begins to be bent. After the telescopic end on the front side of the hydraulic actuator extends forward by a specific distance and stops, the bending work of the grounding round steel of the transmission line is completed.

[0031] 3. The functions of bending and cutting are integrated on a portable machine, with low equipment cost, small occupied space, convenient for carrying, high processing flexibility, capable of reducing the labor intensity of electric power construction personnel, high processing efficiency for the grounding round steel of the transmission line, convenient for accurately regulating the bending angle of the grounding round steel of the transmission line, and high bending accuracy.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] For example, see Figures 1 to 11This embodiment provides a technical solution: an integrated device for bending and cutting round steel for grounding power transmission lines, including a device power body 1, the device power body 1 includes a shell 11 and a hydraulic actuator 12, the hydraulic actuator 12 is installed in the shell 11, and the device power body 1 also includes a power motor 13, a lifting handle 14, a power supply 15, a control handle sleeve 16, a control handle 17, a control panel 18, and a start switch 19.

[0046] A power motor 13 is installed at the rear end of the housing 11, and the output shaft of the power motor 13 is connected to the hydraulic actuator 12. The power motor 13 is a servo motor, which is used to provide power for the hydraulic actuator 12. The hydraulic actuator 12 and the power motor 13 constitute an electro-hydraulic servo actuator or electro-hydraulic servo system in the prior art.

[0047] A control handle sleeve 16 is fixedly sleeved on the outer peripheral side of the front end of the housing 11, and a control handle 17 is installed on the top of the control handle sleeve 16. With the help of the control handle 17, the front end of the device can be held by hand. The top of the housing 11 is connected to the top of the power motor 13 through the lifting handle 14. The lifting handle 14 is used to facilitate lifting the device, and the control handle 17 is convenient for assisting in controlling the device. A start switch 19 is installed on the inner side of the front end of the lifting handle 14, and a control panel 18 is also installed on the top of the housing 11. The output end of the start switch 19 is electrically connected to the input end of the control panel 18, and the output end of the control panel 18 is electrically connected to the input end of the power motor 13. A power supply 15 is detachably installed on the rear end of the lifting handle 14. The power supply 15 supplies power to the control panel 18 and the power motor 13. The control panel 18 controls the operation of the power motor 13 using the existing technology. The start switch 19 plays a triggering role in starting the work, which is convenient for quickly starting the work with the help of the start switch 19 after setting the working mode in the control panel 18. The position of the start switch 19 is convenient for the hand holding the lifting handle 14 to press and use.

[0048] It also includes an integrated head mechanism 2, a bending angle control mechanism 3 and a bending and cutting switching mechanism 5.

[0049] The integrated head mechanism 2 includes a working cover 21, a partition 22, a base 23 and a round steel through groove 24. The front bottom of the housing 11 is fixedly connected to the rear end of the base 23. The working cover 21 is fixedly installed on the upper side of the base 23. The telescopic end of the front side of the hydraulic actuator 12 passes through the through hole in the middle of the working cover 21. The hydraulic actuator 12 adopts the existing technology. The hydraulic actuator 12 includes a hydraulic cylinder inside. The outer end of the piston rod of the hydraulic cylinder is the telescopic end of the front side of the hydraulic actuator 12. The front side of the working cover 21 is provided with a working opening. The working cover 21 is divided into an upper equipment chamber and a lower working chamber by a partition 22. Two round steel through grooves 24 are respectively provided on both sides of the working cover 21 corresponding to the left and right ends of the working chamber.

[0050] The integrated head mechanism 2 further includes a triangular groove 26 and a displacement sensor 27. The bottom of the working cover 21 is provided with a triangular groove 26, and the rear end of the triangular groove 26 is provided with a displacement sensor 27. The triangular groove 26 is used to install the displacement sensor 27, and the displacement sensor 27 is used to detect the distance that the telescopic end of the front side of the hydraulic actuator 12 moves forward. The output end of the displacement sensor 27 is electrically connected to the input end of the control panel 18, and the information detected by the displacement sensor 27 can be transmitted to the control panel 18 through an electrical signal. The electrical connection method between the control panel 18 and the displacement sensor 27 adopts the existing technology.

[0051] Since it is necessary to consider the movement of the two ends of the transmission line grounding round steel 7 during bending, the round steel insertion slot 24 is set wider. When the transmission line grounding round steel 7 is inserted into the round steel insertion slot 24, it is easy to shake. The integrated head mechanism 2 also includes a limiting magnetic block 25. The front ends of the two round steel insertion slots 24 are respectively inlaid with the limiting magnetic blocks 25. When the transmission line grounding round steel 7 passes through the two round steel insertion slots 24, the magnetic attraction of the limiting magnetic block 25 on the transmission line grounding round steel 7 allows the transmission line grounding round steel 7 to be stably located at the front side of the round steel insertion slot 24, reducing the movement of the transmission line grounding round steel 7 in the round steel insertion slot 24.

[0052] The integrated head mechanism 2 further includes a rectangular through slot 28 . Two rectangular through slots 28 are respectively provided on both sides of the bottom of the working cover 21 . The two rectangular through slots 28 are respectively connected to the working chamber.

[0053] The integrated head mechanism 2 also includes a cover 29, and the cover 29 is installed on the front side of the equipment cavity by screws. The cover 29 seals the equipment cavity to prevent external debris from entering the equipment cavity during operation and affecting the normal operation of the components in the equipment cavity.

[0054] A working cover 21 is provided, and the deviation of the grounding round steel 7 of the power transmission line can be limited by means of the round steel insertion groove 24, thereby improving the cutting accuracy and ensuring the safety of the operator.

[0055] The bending angle control mechanism 3 is installed in the working cover 21 .

[0056] The bending angle control mechanism 3 includes a bending column 33, an annular limit groove 34 and an opposite movement control component. Two vertical bending columns 33 are respectively provided on the left and right sides of the front end in the working chamber. The two bending columns 33 are connected to the opposite movement control component, and the opposite movement control component is used to drive the two bending columns 33 to move closer to or away from each other. An annular limit groove 34 is respectively provided in the middle of each bending column 33. In the initial stage, the opposite movement control component drives the two bending columns 33 to move away from each other synchronously. When preparing to bend the transmission line grounding round steel 7, the opposite movement control component synchronously drives the two bending columns 33 to move closer to each other until the two bending columns 33 are at a specific distance. At this time, the two bending columns 33 and the bending end of the bending and cutting switching mechanism 5 form a triangle, and the angle of the front end of the triangle is the preset bending angle of the transmission line grounding round steel 7. The telescopic end on the front side of the hydraulic actuator 12 extends forward a specific distance, so that the distance between the two bending columns 33 is different, and the bending angle of the transmission line grounding round steel 7 is also different, which can complete the control of the bending angle of the transmission line grounding round steel 7. The transmission line grounding round steel 7 is pushed forward by the telescopic end on the front side of the hydraulic actuator 12, and the transmission line grounding round steel 7 is blocked by the two bending columns 33. The transmission line grounding round steel 7 begins to be bent, and the telescopic end on the front side of the hydraulic actuator 12 extends forward a specific distance and then stops, and the bending of the transmission line grounding round steel 7 is completed. The setting of the annular limit groove 34 can limit the transmission line grounding round steel 7, so that the position of the transmission line grounding round steel 7 is kept stable when the bending column 33 contacts the transmission line grounding round steel 7, and the transmission line grounding round steel 7 is prevented from being offset due to the up and down movement of the transmission line grounding round steel 7 relative to the bending column 33 during the bending process, which is conducive to improving the bending accuracy of the transmission line grounding round steel 7.

[0057] The opposite movement control component includes a slide groove 31, a slider 32, a connecting rod 35, a movable shaft 36, a ratchet turntable 37 and a control motor 38. The upper and lower ends of each bending column 33 are respectively fixedly connected to two sliders 32. The upper and lower sides of the working chamber are respectively provided with slide grooves 31 connected to the sliders 32 for transverse sliding. A control motor 38 is installed on the top of the equipment cavity. The output shaft at the bottom of the control motor 38 is fixedly connected to the middle of the ratchet turntable 37. Two movable shafts 36 symmetrical about the center of the ratchet turntable 37 are installed on the ratchet turntable 37. The two movable shafts 36 are respectively rotatably connected to one end of the two connecting rods 35, and the other ends of the two connecting rods 35 are respectively movably connected to the sliders 32 at the top of the two bending columns 33. The connecting rod 35 and the slider 32 at the top of the bending column 33 can be movably connected by a short axis. The ratchet turntable 37, the two movable shafts 36 and the two connecting rods 35 form two groups of structures similar to crank connecting rods. The control motor 38 drives the ratchet turntable 37 to rotate counterclockwise. The ratchet turntable 37 pushes the sliders 32 at the top of the two bending columns 33 away from each other along the respective slide grooves 31 through the two connecting rods 35, thereby driving the two bending columns 33 to move away from each other synchronously. The control motor 38 drives the ratchet turntable 37 to rotate clockwise. The ratchet turntable 37 pulls the sliders 32 at the top of the two bending columns 33 toward each other along the respective slide grooves 31 through the two connecting rods 35, thereby driving the two bending columns 33 to move toward each other synchronously.

[0058] The distance between the two bending columns 33 is different. When the telescopic end on the front side of the hydraulic actuator 12 extends forward a specific distance, the power transmission line grounding round steel 7 is bent into different angles. The distance between the two bending columns 33 is divided into eleven levels, and the power transmission line grounding round steel 7 is bent into 11 levels of 30°, 34°, 40°, 50°, 60°, 70°, 80°, 90°, 100°, 110°, and 120°.

[0059] The bending angle control mechanism 3 also includes a battery 311, and the battery 311 is installed in the equipment cavity. The battery 311 is used to power the control motor 38. The control motor 38 adopts a servo motor that can rotate forward and reverse, and the output end of the control panel 18 is electrically connected to the input end of the control motor 38. The control panel 18 is also used to control the operation of the control motor 38, and its control method adopts the existing technology.

[0060] The bending angle control mechanism 3 further includes a rotating shaft 39, a safety knob 310, and a brake claw 314. A rotating shaft 39 is rotatably connected inside the device cavity. The top of the rotating shaft 39 extends to the upper side of the working cover 21 and is fixedly connected with a safety knob 310. The bottom end of the rotating shaft 39 is fixedly connected with a brake claw 314 that cooperates with the outer peripheral side of the ratchet turntable 37. After the control motor 38 works to control a specific distance between the two bending columns 33, the rotating shaft 39 is rotated through the safety knob 310. The rotating shaft 39 drives the brake claw 314 to rotate, so that the brake claw 314 engages and locks with the ratchet teeth on the outer side of the ratchet turntable 37, completing the locking of the ratchet turntable 37, avoiding the rotation of the ratchet turntable 37 caused by the force on the bending column 33 at the bending part, preventing the control motor 38 from reversing when the bending column 33 is stressed, which is beneficial to improving the bending accuracy and protecting the control motor 38.

[0061] The bending angle control mechanism 3 further includes an oil drain valve 312 and an oil circuit 313. An oil drain valve 312 is installed at the top inside the device cavity. The oil drain valve 312 is connected to the rotating shaft 39, and the oil drain valve 312 is connected to the hydraulic actuator 12 through the oil circuit 313.

[0062] After the bending is completed, the safety knob 310 is rotated in the reverse direction. The safety knob 310 opens the oil drain valve 312 through the rotating shaft 39. The oil drain valve 312 allows the hydraulic oil in the hydraulic actuator 12 to be depressurized through the oil circuit 313, and the telescopic end of the hydraulic actuator 12 cannot be pushed forward, preventing operation errors. Only when the safety knob 310 and the rotating shaft 39 drive the brake claw 314 to engage with the ratchet turntable 37, the oil drain valve 312 is closed, and the telescopic end of the hydraulic actuator 12 can extend forward. At this time, bending and cutting can be carried out, improving safety performance.

[0063] When the oil drain valve 312 is opened, the rotating shaft 39 also drives the brake claw 314 to disengage from the ratchet turntable 37, and then the two bending columns 33 are controlled to move away through the control motor 38. At this time, it is convenient to take away the bent grounding round steel 7 of the transmission line.

[0064] The bending and cutting switching mechanism 5 is installed at the front top of the base 23, and the bending and cutting switching mechanism 5 is arranged corresponding to the telescopic end on the front side of the hydraulic actuator 12 in the front-rear direction.

[0065] The bending and cutting switching mechanism 5 includes a round seat 57, a cutting edge 58, a bending head 59, an arc groove 510, and a switching control component. The front top of the base 23 is connected to the bottom of the round seat 57 through the switching control component. A cutting edge 58 is arranged on one side of the round seat 57, and a bending head 59 is arranged at the other end of the round seat 57. An arc groove 510 is opened at the end of the bending head 59. The cutting edge 58 and the bending head 59 are located in the same plane.

[0066] The switching control assembly is used to drive the round seat 57 to rotate and lock the position of the round seat 57. The cutting blade 58 is used as the cutting end of the bending and cutting switching mechanism 5. When cutting the transmission line grounding round steel 7, the cutting blade 58 needs to face backward. The bending head 59 is used as the bending end of the bending and cutting switching mechanism 5. When bending the transmission line grounding round steel 7, the bending head 59 needs to face backward. If the bending part of the transmission line grounding round steel 7 is close to the bending head 59, the arc groove 510 can limit the bending part of the transmission line grounding round steel 7, which is conducive to maintaining the stability of the transmission line grounding round steel 7.

[0067] The switching control assembly includes a vertical cylinder 51, a fastening bolt 52, a switching shaft 53, a rotating disk 54, a limiting card strip 55 and a compression spring 56. A circular blind hole is provided at the top of the front end of the base 23, and a limiting strip groove is provided at the bottom of the circular blind hole. The vertical cylinder 51 is fixedly connected to the circular blind hole by a fastening bolt 52. The bottom of the vertical cylinder 51 is open, and an interpenetrating circular hole is provided at the top center of the vertical cylinder 51. The switching shaft 53 is vertically interpenetrated at the top center of the vertical cylinder 51. The bottom end of the switching shaft 53 is fixedly connected to the rotating disk 54, and a limiting card strip 55 cooperating with the limiting strip groove is provided at the bottom of the rotating disk 54. The limiting card strip 55 is located in the same plane as the cutting blade 58 and the bending head 59, and the part of the switching shaft 53 located in the vertical cylinder 51 is sleeved with a compression spring 56.

[0068] When the limit card strip 55 is engaged with the limit bar slot, the cutting blade 58 and the bending head 59 are both longitudinally distributed, and the front and rear directions of the cutting blade 58 and the bending head 59 need to be switched, the round seat 57 is lifted upward, driving the switching shaft 53 and the rotating disk 54 to move upward relative to the vertical cylinder 51, at which time the compression spring 56 is compressed, and the limit card strip 55 is separated from the limit bar slot. The round seat 57 is rotated 180°, the round seat 57 is released, the compression spring 56 is reset and extended, and the switching shaft 53 and the rotating disk 54 are pushed downward relative to the vertical cylinder 51 again, and the limit card strip 55 is re-engaged with the limit bar slot, and the position of the round seat 57 is re-locked, and the front and rear positions of the cutting blade 58 and the bending head 59 are switched, thereby allowing the cutting blade 58 to face backward or the bending head 59 to face backward.

[0069] When in use, the partition 22 divides the working cover 21 into two chambers, wherein the equipment chamber is used to install the main body of the bending angle control mechanism 3, and the bending and cutting switching mechanism 5 is used to control whether the equipment performs a cutting function or a bending function, wherein the bending angle control mechanism 3 is not required to function when the equipment performs a cutting function.

[0070] When it is necessary to cut the transmission line grounding round steel 7, the cutting end of the bending and cutting switching mechanism 5 is facing backward, the transmission line grounding round steel 7 is passed through between the two round steel insertion grooves 24, and the transmission line grounding round steel 7 is placed at the front end of the two round steel insertion grooves 24. The telescopic end of the front side of the hydraulic actuator 12 extends forward, pushing the transmission line grounding round steel 7 gradually close to the cutting end of the bending and cutting switching mechanism 5 until the transmission line grounding round steel 7 is cut off.

[0071] When it is necessary to bend the transmission line grounding round steel 7, the bending end of the bending and cutting switching mechanism 5 is directed backward, the transmission line grounding round steel 7 is passed through between the two round steel insertion grooves 24, and the transmission line grounding round steel 7 is placed at the front end of the two round steel insertion grooves 24. The telescopic end of the front side of the hydraulic actuator 12 extends forward to push the transmission line grounding round steel 7 to bend forward step by step. The bending angle control mechanism 3 blocks the front sides of both ends of the transmission line grounding round steel 7, thereby controlling the bending angle of the transmission line grounding round steel 7. The telescopic end of the front side of the hydraulic actuator 12 stops after extending forward a specific distance, and the bending process of the transmission line grounding round steel 7 is completed.

[0072] For example 2, please refer to Figures 1 to 11 This embodiment provides a technical solution: an integrated device for bending and cutting round steel for grounding of power transmission lines. The structure of this embodiment is roughly the same as that of the first embodiment, except that:

[0073] It also includes a round steel bending and cutting pushing mechanism 4, which includes a disassembly seat 41, a rotating shaft 42, a pushing block 43 and a locking assembly. The telescopic end on the front side of the hydraulic actuator 12 is detachably mounted with the disassembly seat 41, and the rear end of the disassembly seat 41 and the telescopic end on the front side of the hydraulic actuator 12 are disassembled by a card connection. The disassembly seat 41 is rotatably connected with a pushing block 43 through a vertical rotating shaft 42, one end of the pushing block 43 is set to be in an arc shape, and the other end of the pushing block 43 is set to be an isosceles trapezoidal structure, and the pushing block 43 is connected to the disassembly seat 41 through a locking assembly.

[0074] The round steel bending and cutting pushing mechanism 4 also includes a locking hole 44 and a locking bolt 45. Two locking holes 44 are arranged on the upper side of the pushing block 43. The two locking holes 44 are arranged symmetrically about the axis of the rotating shaft 42. The countersunk hole on the disassembly seat 41 is threadedly connected with a locking bolt 45, and the bottom of the locking bolt 45 extends into the corresponding locking hole 44. After the locking bolt 45 is twisted, the pushing block 43 is rotated 180° relative to the rotating shaft 42, and the locking bolt 45 will correspond to another locking hole 44. The locking bolt 45 is tightened, and the bottom of the locking bolt 45 extends into another locking hole 44, so that the pushing block 43 and the disassembly seat 41 can be locked together again.

[0075] The disassembly seat 41 can be taken out from the telescopic end on the front side of the hydraulic actuator 12 through the rectangular through slot 28, and then the push block 43 can be adjusted through the locking assembly. The structure of the push block 43 facing the front end can be selected as needed.

[0076] When the transmission line grounding round steel 7 is bent, if the bending part of the transmission line grounding round steel 7 needs to be in an arc shape, the push block 43 is rotated relative to the disassembly seat 41 through the rotating shaft 42, so that the end of the push block 43 in an arc shape faces forward, and the locking assembly locks the disassembly seat 41 and the push block 43. If the bending part of the transmission line grounding round steel 7 needs to have a more obvious bending angle, the end of the push block 43 with an isosceles trapezoidal structure faces forward, and then the locking assembly locks the disassembly seat 41 and the push block 43, wherein the distances between the two ends of the push block 43 and the center of the rotating shaft 42 are the same, and no matter which end faces forward, the pushing distance of the transmission line grounding round steel 7 is consistent.

[0077] When cutting the grounding round steel bar 7 of the power transmission line, the cutting effect will not be affected if either end of the push block 43 faces forward.

[0078] For example 3, please refer to Figures 1 to 11 This embodiment provides a technical solution: an integrated device for bending and cutting round steel for grounding of power transmission lines. The structure of this embodiment is roughly the same as that of the second embodiment, except that:

[0079] It also includes a bending and cutting length control mechanism 6, which includes a sliding sleeve 61, a sliding bar 62, a control baffle 63 and a butterfly bolt 64. The bottom side of the working cover 21 is fixedly connected with a sliding sleeve 61 at a position corresponding to the front end of the round steel insertion slot 24. The sliding sleeve 61 is laterally slidably connected with a sliding bar 62. The upper side of the end of the sliding bar 62 away from the working cover 21 is fixedly connected with a control baffle 63. The bottom of the sliding sleeve 61 is threadedly connected with a butterfly bolt 64, and the butterfly bolt 64 is pressed against the sliding bar 62. The two sides of the sliding bar 62 are respectively provided with scales. The control baffle 63 is arranged corresponding to the end of the transmission line grounding round steel 7 to be bent. Loosening the butterfly bolt 64 can allow the sliding bar 62 to slide along the sliding sleeve 61, thereby changing the distance between the control baffle 63 and the push block 43, thereby changing the position of bending or cutting the transmission line grounding round steel 7. Tighten the butterfly bolt 64 to lock the position of the slide bar 62 and the control baffle 63. Then, each time the grounding round steel bar 7 of the transmission line is passed through the front side of the two round steel insertion slots 24, the end of the grounding round steel bar 7 of the transmission line close to the control baffle 63 is pressed against the side of the control baffle 63 close to the working cover 21. It is convenient to control the position of the bending or cutting of the grounding round steel bar 7 of the transmission line, which is conducive to playing a role when the same grounding round steel bar 7 of the transmission line is repeatedly bent or cut.

[0080] See also Figures 1 to 11, How to use the integrated equipment for bending and cutting round steel for grounding of power transmission lines:

[0081] When bending:

[0082] By switching the control component to make the bending head 59 on the round seat 57 face backward, the transmission line grounding round steel 7 is passed through the front side of the two round steel insertion grooves 24. At this time, the transmission line grounding round steel 7 is located between the two bending columns 33 and the bending head 59.

[0083] The bending angle is set in the control panel 18 , and the system rotates the control motor 38 according to the bending angle, driving the ratchet turntable 37 to rotate. The ratchet turntable 37 controls the two bending columns 33 to move synchronously closer to each other through the connecting rod 35 .

[0084] The distance between the two bending columns 33 has 11 values, and the 11 values ​​correspond to the transmission line grounding round steel 7 being bent into 11 standard bending angles of 30°, 34°, 40°, 50°, 60°, 70°, 80°, 90°, 100°, 110°, and 120°.

[0085] If the bending angle of the transmission line grounding round steel 7 is exactly 30°, 34°, 40°, 50°, 60°, 70°, 80°, 90°, 100°, 110°, 120°, etc., the distance between the two bending columns 33 is moved to the corresponding value, and the telescopic end of the hydraulic actuator 12 is uniformly pushed forward 60 mm to bend the transmission line grounding round steel 7 into the above-mentioned required standard bending angle.

[0086] Then, the safety knob 310 is turned, and the rotating shaft 39 drives the braking claw 314 to disengage from the ratchet turntable 37, and then the two bending columns 33 are controlled to move away by the control motor 38, so that it is convenient to take away the bent power transmission line grounding round steel 7.

[0087] The rotation of the safety knob 310 also opens the oil unloading valve 312 through the rotating shaft 39. The oil unloading valve 312 releases the hydraulic oil in the hydraulic actuator 12 through the oil circuit 313, so that the telescopic end of the hydraulic actuator 12 cannot be pushed forward, thereby preventing operational errors.

[0088] Only when the safety knob 310 and the rotating shaft 39 drive the braking claw 314 to engage with the ratchet rotating disk 37, the oil unloading valve 312 is closed, and the telescopic end of the hydraulic actuator 12 can be extended forward, and bending and cutting can be performed at this time, thereby improving safety performance.

[0089] If the bending angle is non-standard, first adjust the bending angle of the machine to be close to the standard angle through the control panel 18, and then detect the position of the telescopic end of the front side of the hydraulic actuator 12 through the displacement sensor 27 below. Through system calculation, the telescopic end of the front side of the hydraulic actuator 12 is allowed to continue to extend a certain distance to perform angle compensation.

[0090] For example, for a 54° bending angle, the telescopic end of the front side of the hydraulic actuator 12 needs to be extended forward 60 mm to bend the transmission line grounding round steel 7 to a 60° level, and then the telescopic end of the front side of the hydraulic actuator 12 continues to advance 7.99 mm to achieve a 54° bending effect.

[0116] When cutting:

[0117] By switching the control component to make the cutting edge 58 on the round seat 57 face backward, the power transmission line grounding round steel 7 is passed through the front side of the two round steel insertion grooves 24. At this time, the power transmission line grounding round steel 7 is located between the two bending columns 33 and the cutting edge 58.

[0118] Select the cutting mode in the control panel 18. At this time, the control motor 38 stops working after the distance between the two bending columns 33 is at the maximum state. The telescopic end of the hydraulic actuator 12 moves forward 70 mm, and the grounding round steel 7 of the power transmission line is cut by the cutting blade 58, completing the cutting.
