[0015] A method for using a buffer device for dropping angle steel of an electric power tower comprises the following steps:

[0016] Step 1: After the cutting is completed, the angle steel plate is dropped vertically, and the angle steel plate enters the interior of the receiving shell, and then the angle steel plate falls to the top of the buffer plate;

[0017] Step 2: The gravity generated will cause the buffer plate to move downward. Due to the setting of the vertical slot, the buffer plate drives the lifting block to fall vertically along the outside of the vertical slot;

[0018] Step 3: When the buffer plate moves down to the inner bottom of the receiving shell, the angle steel plate slides along the inclination angle of the buffer plate due to the opening setting of the discharge hole and the inclination setting of the buffer plate;

[0019] Step 4: The angle steel plate moves outward through the opening of the discharge hole, and the angle steel plate is subsequently processed after cutting.

[0020] The present invention has the following beneficial effects:

[0021] According to the present invention, the angle steel plate will fall vertically after cutting, and the angle steel plate will enter the interior of the receiving shell, and then the angle steel plate will fall to the top of the buffer plate. The gravity generated will cause the buffer plate to move downward. Due to the setting of the vertical groove, the buffer plate drives the lifting block to fall vertically along the outside of the vertical groove. In the process of the buffer plate driving the angle steel plate to fall vertically, the impact force generated when the angle steel plate falls can be buffered, so as to prevent the impact force generated when the angle steel plate falls from being too large, causing the outer wall of the angle steel plate to be damaged, thereby improving the device's protection against the angle steel The protective effect of the plate, when the buffer plate moves down to the inner bottom end of the receiving shell, due to the opening setting of the discharge hole and the tilt setting of the buffer plate, the angle steel plate slides along the tilt angle of the buffer plate, and the angle steel plate moves outward through the opening of the discharge hole, so as to carry out subsequent processing of the angle steel plate after cutting, and in this process, it can prevent the subsequently cut angle steel plate from contacting with the angle steel plate on the top of the buffer plate, so that the subsequent angle steel plate causes impact damage to the angle steel plate on the top of the buffer plate, thereby indirectly improving the protective effect of the device on the angle steel plate.

[0022] (2) According to the present invention, when the buffer plate moves downward, the buffer plate and the fixed block gradually approach each other. During the process of the two approaching each other, the rotating rod will rotate around the fixed block. Due to the setting of the limit rod, the rotating rod will drive the slider to slide along the outer wall of the limit rod during the rotation process. The slider drives the special-shaped connecting rod to move, the special-shaped connecting rod drives the vertical plate to move, the vertical plate drives the telescopic rod to move, the telescopic rod drives the concave frame to move, and the concave frame drives the rectangular scraper to move. During the movement of the rectangular scraper, the debris that falls to the top of the buffer plate will be scraped off to prevent the debris from remaining on the top of the buffer plate. When the angle steel plate falls and contacts the debris, it will cause scratches on the outer wall of the angle steel plate, thereby improving the protective effect of the device on the angle steel plate. In addition, the concave frame drives the cross bar to move, and the cross bar drives the cleaning roller to move. During the movement of the cleaning roller, the angle steel plate on the top of the buffer plate is pushed to prevent the angle steel plate from staying on the top of the buffer plate, thereby further preventing the angle steel plate on the top of the buffer plate from contacting and colliding with the angle steel plate cut subsequently.

[0023] (3) In the present invention, the cleaning roller pushes the angle steel plate to slide on the top of the buffer plate, so that the angle steel plate will come into contact with one side of the protective strip, and the protective strip supports the angle steel plate. When the buffer plate falls to the discharge hole, the angle steel plate drives the protective strip to slide due to its own gravity, and the protective strip drives the round rod to move, and the round rod drives the first clamping block to slide inside the protective shell. When the angle steel plate completely slides to the outside of the receiving shell, it will be collected by the staff. Due to the elastic deformation of the reset spring, the sliding rate of the first clamping block can be reduced to a certain extent, and the sliding speed of the angle steel plate can be reduced laterally to prevent the angle steel plate from being excessively hit when it is discharged to the outside, thereby improving the protective effect of the device on the angle steel plate.

[0024] (4) In the present invention, when the cross bar moves, the cross bar drives the gear to move. During the movement of the gear, it will contact the rack, causing the gear to rotate in a circle. The gear and the cross bar rotate together. The cross bar drives the cleaning roller to rotate. During the rotation of the cleaning roller, it will contact the top of the buffer plate, further cleaning the debris on the top of the buffer plate, thereby improving the protective effect of the device on the diagonal steel plate. At the same time, during the falling process, the concave frame drives the fixed shell to move, the fixed shell drives the extrusion spring to move, and the extrusion spring drives the second card block to move. When the second card block moves to the first card block, the two come into contact, and the second card block is squeezed by the first card block. The second card block moves along the outer surface of the fixed rod. The wall moves up, and the second clamping block continues to move. At this time, the second clamping block no longer contacts the first clamping block, and the second clamping block is elastically squeezed by the extrusion spring, and the second clamping block and the first clamping block will be clamped. When the angle steel plate is discharged, the angle steel plate drives the protective strip to move, the protective strip drives the round rod to move, the round rod drives the first clamping block to move, the first clamping block drives the second clamping block to move, and the second clamping block drives the cleaning roller in the cleaning assembly to move, and the cleaning roller rotates while moving, thereby further cleaning the debris on the top of the buffer plate, so that the debris is discharged outward through the discharge hole of the receiving shell, the cleaning range of the cleaning roller is expanded, and the protective effect of the device on the angle steel plate is improved laterally.

[0025] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0040] Example 1, please refer to Figure 1 - Fig.10 As shown, the present invention is a buffer device for angle steel falling of an electric power tower and a method for using the same, comprising a receiving shell 1, a plurality of table legs 2 are fixedly connected to the bottom and four sides of the receiving shell 1, a flexible protective cover 3 is fixedly connected to the top of the receiving shell 1, the flexible protective cover 3 is made of rubber to prevent the angle steel plate from colliding with it when it falls and causing damage to the angle steel plate, a discharge hole 4 is opened at the bottom end of one side of the receiving shell 1, and further comprising;

[0041] The material-falling buffer mechanism 5 comprises vertical slots 51 on both sides of the inner wall of the receiving shell 1. The bottom of the inner wall of the vertical slot 51 is fixedly connected with a spring 52. The purpose of this arrangement is to facilitate resetting. The top of the spring 52 is fixedly connected with a lifting block 53. The outer wall of the lifting block 53 is slidably connected to the inner wall of the vertical slot 51. An inclined buffer plate 54 is fixedly connected between the two lifting blocks 53. After the cutting is completed, the angle steel plate falls vertically. At this time, the angle steel plate will enter the interior of the receiving shell 1, and then the angle steel plate will fall to the top of the buffer plate 54. The gravity generated will cause the buffer plate 54 to move downward. Affected by the setting of the vertical slot 51, the buffer plate 54 drives the lifting block 53 to fall vertically along the outside of the vertical slot 51. In the process of the buffer plate 54 driving the angle steel plate to fall vertically, The impact force generated when the angle steel plate falls is buffered to prevent the impact force generated when the angle steel plate falls from being too large, causing the outer wall of the angle steel plate to be damaged, thereby improving the protective effect of the device on the angle steel plate. A sliding component 55 is provided at the bottom of the buffer plate 54. When the buffer plate 54 moves down to the inner bottom end of the receiving shell 1, it is affected by the opening setting of the discharge hole 4 and the inclined setting of the buffer plate 54. The angle steel plate slides along the inclined angle of the buffer plate 54, and the angle steel plate moves outward through the opening of the discharge hole 4, so as to perform subsequent processing on the angle steel plate after cutting. In this process, the subsequently cut angle steel plate can be prevented from contacting the angle steel plate on the top of the buffer plate 54, so that the subsequent angle steel plate causes impact damage to the angle steel plate on the top of the buffer plate 54, thereby indirectly improving the protective effect of the device on the angle steel plate.

[0042] In embodiment 2, the sliding assembly 55 includes a limiting rod 551 fixedly connected to the bottom of the buffer plate 54, a fixed block 552 is fixedly connected to one side of the bottom of the inner wall of the receiving shell 1, a rotating rod 553 is rotatably connected to one side of the inner wall of the fixed block 552, and a sliding block 554 is rotatably connected to one end of the rotating rod 553 away from the fixed block 552.

[0043] The inner wall of the slider 554 is slidably connected to the outer wall of the limiting rod 551, and the two sides of the slider 554 are fixedly connected with special-shaped connecting rods 555. Square holes 556 are respectively opened on both sides of the bottom of the buffer plate 54, and the outer wall of the end of the special-shaped connecting rod 555 away from the slider 554 is slidably connected to the inner wall of the square hole 556.

[0044] A pusher assembly 56 is provided at the top of the special-shaped connecting rod 555, and the pusher assembly 56 includes a vertical plate 561 fixedly connected to the top of the special-shaped connecting rod 555, a telescopic rod 562 is fixedly connected to one side of the vertical plate 561, and a vertical hole 563 is opened on the side of the receiving shell 1 away from the discharge hole 4.

[0045] The outer wall of the fixed end of the telescopic rod 562 is slidably connected to the inner wall of the vertical hole 563. The purpose of this arrangement is to prevent the telescopic rod 562 from getting stuck during the lifting process. The movable end of the telescopic rod 562 passes through the vertical plate 561 and extends to the outside of the vertical plate 561. The movable end of the telescopic rod 562 is fixedly connected to a concave frame 564. The bottom of the concave frame 564 is fixedly connected to a rectangular scraper 565. The bottom of the rectangular scraper 565 is slidably connected to the top of the buffer plate 54. When the buffer plate 54 moves downward, the buffer plate 54 and the fixed block 552 gradually approach each other. During the approach of the two, the rotating rod 553 will rotate around the fixed block 552, which is affected by the limiting rod 551. The arrangement is such that during the rotation of the rotating rod 553, the slider 554 is driven to slide along the outer wall of the limiting rod 551, the slider 554 drives the special-shaped connecting rod 555 to move, the special-shaped connecting rod 555 drives the vertical plate 561 to move, the vertical plate 561 drives the telescopic rod 562 to move, the telescopic rod 562 drives the concave frame 564 to move, the concave frame 564 drives the rectangular scraper 565 to move, and during the movement of the rectangular scraper 565, the debris that falls to the top of the buffer plate 54 is scraped off to prevent the debris from remaining on the top of the buffer plate 54, and when the angle steel plate falls and contacts with the debris, the outer wall of the angle steel plate is scratched, thereby improving the protective effect of the device on the angle steel plate.

[0046] A protective component 57 is provided on the side wall of the vertical plate 561, and protective shells 571 are fixedly connected to both ends of one side of the vertical plate 561. The purpose of this arrangement is to block the square hole 556 to prevent debris from falling into the interior of the receiving shell 1. A return spring 572 is fixedly connected to one end of the inner wall of the protective shell 571, and a first clamping block 573 is fixedly connected to one end of the return spring 572. The outer wall of the first clamping block 573 is slidably connected to the inner wall of the protective shell 571, and a round rod 574 is fixedly connected to one end of the first clamping block 573 away from the return spring 572.

[0047] One end of the round rod 574 passes through the protective shell 571 and extends to the outside of the protective shell 571. The end of the round rod 574 away from the first clamping block 573 is fixedly connected to a protective strip 575. A limiting groove 576 is provided on one side of the outer wall of the protective shell 571. The top outer wall of the first clamping block 573 is slidably connected to the inner wall of the limiting groove 576. The protective strip 575 supports the angle steel plate. When the buffer plate 54 falls to the discharge hole 4, the angle steel plate drives the protective strip 575 to slide due to the gravity of the angle steel plate. The protective strip 575 drives the round rod 574 to move, and the round rod 574 drives the first block 573 to slide inside the protective shell 571. When the angle steel plate completely slides to the outside of the receiving shell 1, it will be collected by the staff. The elastic deformation of the reset spring 572 can reduce the sliding rate of the first block 573 to a certain extent, and the sliding speed of the angle steel plate can be reduced laterally to prevent excessive impact when the angle steel plate is discharged to the outside, thereby improving the protective effect of the device on the angle steel plate.

[0048] A cleaning assembly 58 is provided on the inner wall of the concave frame 564, and the cleaning assembly 58 includes a cross bar 581 that penetrates and rotatably connects to both sides of the inner wall of the concave frame 564, and a cleaning roller 582 is fixedly connected to the outer wall of the middle end of the cross bar 581. The concave frame 564 drives the cross bar 581 to move, and the cross bar 581 drives the cleaning roller 582 to move. During the movement of the cleaning roller 582, the angle steel plate at the top of the buffer plate 54 is pushed to prevent the angle steel plate from staying on the top of the buffer plate 54, and further prevents the angle steel plate at the top of the buffer plate 54 from contacting and colliding with the subsequently cut angle steel plate. The outer walls at both ends of the cross bar 581 are respectively fixedly connected with gears 583, and one side of the outer wall of the gear 583 is meshingly connected with a rack 584, and the bottom of the rack 584 is fixedly connected to the top of the buffer plate 54.

[0049] A fixed shell 585 is fixedly connected to both sides of the outer wall of the concave frame 564, and a fixed rod 586 is fixedly connected to the top of the inner wall of the fixed shell 585. A second clamping block 588 is slidably connected to the outer wall of one end of the fixed rod 586. One end of the second clamping block 588 penetrates the fixed shell 585 and extends to the outside of the fixed shell 585. An extrusion spring 587 is fixedly connected to the top of the second clamping block 588, and the top end of the extrusion spring 587 is fixedly connected to the top of the inner wall of the fixed shell 585.

[0050] A method for using a buffer device for dropping angle steel of an electric power tower comprises the following steps:

[0051] Step 1: After the cutting is completed, the angle steel plate is dropped vertically, and the angle steel plate enters the interior of the receiving shell 1, and then the angle steel plate falls to the top of the buffer plate 54;

[0052] Step 2: The generated gravity causes the buffer plate 54 to move downward. Due to the setting of the vertical slot 51, the buffer plate 54 drives the lifting block 53 to fall vertically along the outside of the vertical slot 51;

[0053] Step 3: When the buffer plate 54 moves down to the inner bottom end of the receiving shell 1, the angle steel plate slides along the inclination angle of the buffer plate 54 due to the opening setting of the discharge hole 4 and the inclination setting of the buffer plate 54;

[0054] Step 4: The angle steel plate moves outward through the opening of the discharge hole 4, and the angle steel plate after cutting is subsequently processed.

[0055] When in use, the angle steel plate will fall vertically after cutting, and the angle steel plate will enter the interior of the receiving shell 1, and then the angle steel plate will fall to the top of the buffer plate 54. The gravity generated will cause the buffer plate 54 to move downward. Affected by the setting of the vertical slot 51, the buffer plate 54 drives the lifting block 53 to fall vertically along the outside of the vertical slot 51. In the process of the buffer plate 54 driving the angle steel plate to fall vertically, the impact force generated when the angle steel plate falls can be buffered, so as to prevent the impact force generated when the angle steel plate falls from being too large, causing the outer wall of the angle steel plate to be damaged, thereby improving the device's protection against the angle steel The protective effect of the plate is that when the buffer plate 54 moves down to the inner bottom end of the receiving shell 1, due to the opening setting of the discharge hole 4 and the inclined setting of the buffer plate 54, the angle steel plate slides along the inclined angle of the buffer plate 54, and the angle steel plate moves outward through the opening of the discharge hole 4, so as to perform subsequent processing on the angle steel plate after cutting. In this process, the subsequently cut angle steel plate can be prevented from contacting the angle steel plate on the top of the buffer plate 54, so that the subsequent angle steel plate causes impact damage to the angle steel plate on the top of the buffer plate 54, thereby indirectly improving the protective effect of the device on the angle steel plate.

[0056] When the buffer plate 54 moves downward, the buffer plate 54 and the fixed block 552 gradually approach each other. During the approach of the two, the rotating rod 553 will rotate around the fixed block 552. Due to the setting of the limiting rod 551, the rotating rod 553 will drive the slider 554 to slide along the outer wall of the limiting rod 551 during the rotation. The slider 554 drives the special-shaped connecting rod 555 to move, the special-shaped connecting rod 555 drives the vertical plate 561 to move, the vertical plate 561 drives the telescopic rod 562 to move, the telescopic rod 562 drives the concave frame 564 to move, and the concave frame 564 drives the rectangular scraper 565 to move. During the movement of the rectangular scraper 565, the debris that falls to the top of the buffer plate 54 will be scraped off to prevent the debris from remaining on the top of the buffer plate 54. When the angle steel plate falls and contacts the debris, it will scratch the outer wall of the angle steel plate, thereby improving the protective effect of the device on the angle steel plate. The concave frame 564 drives the cross bar 581 to move, and the cross bar 581 drives the cleaning roller 582 to move. During the movement of the cleaning roller 582, the angle steel plate on the top of the buffer plate 54 is pushed to prevent the angle steel plate from staying on the top of the buffer plate 54, thereby further preventing the angle steel plate on the top of the buffer plate 54 from contacting and colliding with the subsequently cut angle steel plate.

[0057] The cleaning roller 582 pushes the angle steel plate to slide on the top of the buffer plate 54, so that the angle steel plate will contact one side of the protective strip 575, and the protective strip 575 supports the angle steel plate. When the buffer plate 54 falls to the discharge hole 4, the angle steel plate drives the protective strip 575 to slide due to the gravity of the angle steel plate itself, and the protective strip 575 drives the round rod 574 to move, and the round rod 574 drives the first block 573 to slide inside the protective shell 571. When the angle steel plate completely slides to the outside of the receiving shell 1, it will be collected by the staff. Due to the elastic deformation of the return spring 572, the sliding rate of the first block 573 can be reduced to a certain extent, and the sliding speed of the angle steel plate can be reduced laterally to prevent the angle steel plate from being excessively hit when it is discharged to the outside, thereby improving the protective effect of the device on the angle steel plate.

[0058] When the cross bar 581 moves, the cross bar 581 drives the gear 583 to move. During the movement, the gear 583 will contact the rack 584, so that the gear 583 rotates in a circle. The gear 583 rotates together with the cross bar 581. The cross bar 581 drives the cleaning roller 582 to rotate. During the rotation, the cleaning roller 582 will contact the top of the buffer plate 54, further cleaning the debris on the top of the buffer plate 54, thereby improving the protection effect of the device on the diagonal steel plate. At the same time, during the falling process, the concave frame 564 drives the fixed shell 585 to move, and the fixed shell 585 drives the extrusion spring 587 to move. The extrusion spring 587 drives the second clamping block 588 to move. When the second clamping block 588 moves to the first clamping block 573, the two come into contact, and the second clamping block 588 is squeezed by the first clamping block 573. The second clamping block 588 moves along the fixed rod 586. The outer wall of the buffer plate 54 moves upward, and the second clamping block 588 continues to move. At this time, the second clamping block 588 is no longer in contact with the first clamping block 573. The second clamping block 588 is elastically squeezed by the extrusion spring 587, and the second clamping block 588 and the first clamping block 573 are clamped. When the angle steel plate is discharged, the angle steel plate drives the protective strip 575 to move, the protective strip 575 drives the round rod 574 to move, the round rod 574 drives the first clamping block 573 to move, the first clamping block 573 drives the second clamping block 588 to move, and the second clamping block 588 drives the cleaning roller 582 in the cleaning assembly 58 to move. The cleaning roller 582 rotates while moving, thereby further cleaning the debris on the top of the buffer plate 54, so that the debris is discharged outward through the discharge hole 4 of the receiving shell 1, and the cleaning range of the cleaning roller 582 is expanded, thereby improving the protective effect of the device on the angle steel plate.
