Description

Technical Field

[0003] The processing of cable anti-fall fittings is a complex and critical process, which is directly related to the safety and stability of the power system. It usually adopts cutting, stamping, drilling and surface treatment manufacturing processes. For example, the Chinese patent application with publication number CN117066561A discloses an automatic drilling device for processing power fittings. The device can limit the nut by setting an extrusion component to achieve the effect of clamping the power fittings, and reduce the indentation on the outer surface of the power fittings when drilling;

[0004] The existing drilling device for electric hardware clamps the electric hardware by arranging a clamping device and a squeezing device, so as to improve the stability of the electric hardware to a certain extent. However, in actual operation, since the existing drilling device can only clamp at one end of the anti-fall hardware, when drilling the other end of the anti-fall hardware, the anti-fall hardware lacks proper support near the drill bit, which makes the anti-fall hardware easy to deform and displace under the pressure of the drill bit, which will not only have an adverse effect on the drilling accuracy of the anti-fall hardware, but also affect the clamping stability of the anti-fall hardware.

[0034] See also Figures 1 to 9 , a hole-making device for an electric power construction anti-fall device, comprising a support seat 11, a fixing cylinder 18 for placing a hardware 15 is fixedly connected to the outer surface of the upper end of the support seat 11, a placing seat 20 is fixedly connected to the lower end of the inner surface of the fixing cylinder 18, and a clamping assembly is arranged on the upper side of the fixing cylinder 18;

[0035] The clamping assembly includes a support plate 19 fixedly connected to the outer surface of the upper end of the fixed cylinder 18, the outer surface of the upper end of the support plate 19 is rotatably connected to the driving plate 30, the outer surface of the upper end of the support plate 19 is provided with a guide groove 14, the inner surface of the guide groove 14 is slidably connected to a guide rod 23, the upper part of the outer surface of the guide rod 23 is fixedly connected to a movable frame 22, the outer surface of the movable frame 22 is fixedly connected to the extrusion plate 21 on the side close to the hardware 15, the outer surface of the driving plate 30 is provided with a guide groove 25, the guide rod 23 passes through the upper and lower ends of the driving plate 30 through the guide groove 25, and the clamping assembly is used to clamp and fix the hardware 15.

[0036] The number of the guide grooves 1 24 and 25 is multiple and they are distributed in a ring array. The movable frame 22 is an L-shaped structure. The extrusion plate 21 is arc-shaped. The outer surface of the extrusion plate 21 is in contact with the outer surface of the hardware 15 away from the movable frame 22. The driving plate 30 and the support plate 19 are both distributed in a circular ring shape.

[0037] By adopting the above technical scheme, when the anti-falling power hardware 15 is subjected to batch drilling processing, in order to ensure the drilling accuracy and reduce the probability of accidental movement of the anti-falling hardware 15 during the drilling process, a clamping assembly is provided, and the support seat 11 lifts and supports the fixed cylinder 18. When working, the lower end of the hardware 15 is placed inside the fixed cylinder 18, and the hardware 15 is lifted and supported by the placement seat 20 on the lower side of the fixed cylinder 18. The driving plate 30 and the support plate 17 are both annular, and the hardware 15 is located in the middle of the driving plate 30 and the support plate 17. After the hardware 15 is placed in place, the operator rotates the driving plate 30, and the driving plate 30 will drive the guide groove 25 on its surface to move synchronously during the movement. The guide groove 25 is inclined. As the driving plate 30 rotates The driving plate 30 drives the guide rod 23 to move along the inside of the guide groove 1 24 toward the center of the driving plate 30 through the guide groove 25, and the multiple groups of guide rods 23 distributed in a ring array will drive the movable frame 22 to move synchronously. The movable frame 22 will drive the extrusion plate 21 to move toward the side of the hardware 15 during the movement. The hardware 15 is clamped and fixed by a plurality of groups of extrusion plates 21 and the outer surface of the hardware 15, so that the hardware 15 is in a stable state. By setting a clamping assembly, the hardware 15 can be conveniently clamped, and the hardware 15 can be kept stable during the drilling process of the hardware 15, which can effectively reduce the probability of accidental movement of the hardware 15, thereby effectively reducing the drilling error and helping to improve the drilling accuracy of the anti-fall hardware 15.

[0038] like Figure 4 and Figure 6 As shown, a positioning assembly is provided on the outside of the hardware 15, and the positioning assembly includes a top plate 16 fixedly connected to the outer surface of the upper end of the support seat 11, and a support plate 17 is fixedly connected to the upper side of the outer surface of the top plate 16, and the support plate 17 is in a circular ring shape. A sleeve 36 is fixedly connected to the outer surface of the lower end of the support plate 17, and an elastic plate 41 is fixedly connected to the outer surface of the lower end of the support plate 17, and the elastic plate 41 is in an arc shape. The number of the elastic plates 41 is several groups and distributed in a ring array, and the lower end of the elastic plate 41 is in contact with the outer surface of the hardware 15.

[0039] The upper and lower ends of the sleeve 36 are open, and the inner surface of the sleeve 36 is symmetrically provided with displacement grooves 37. The inner surface of the displacement groove 37 is slidably connected to a movable seat 39. The outer surface of the upper end of the movable seat 39 is fixedly connected to a traction rope 38. The upper end of the traction rope 38 is fixedly connected to the outer surface of the lower end of the support plate 17. An extrusion tube 40 is fixedly connected between the two groups of movable seats 39. The outer surface of the extrusion tube 40 is in sliding contact with the outer surface of the elastic plate 41. The positioning assembly is used to clamp and position the hardware 15.

[0040] By adopting the above technical solution, the support seat 11 lifts and supports the support plate 17 through the top plate 16, and the support plate 17 is used to pull and support the sleeve 36. When the hardware 15 is put in, the lower end of the hardware 15 passes through the middle of the support plate 17. When the hardware 15 passes through the inside of the sleeve 36, its outer surface will slide and contact with the lower end of the elastic plate 41. The middle of the hardware 15 can be clamped by a plurality of groups of annularly distributed elastic plates 41. The elastic plate 41 cooperates with the clamping assembly to clamp and fix the hardware 15 at different positions of the hardware 15, thereby further improving the clamping stability of the anti-fall hardware 15. The support plate 17 is connected to the traction rope 38 The movable seat 39 is pulled and supported, and the displacement groove 37 on the inner side of the sleeve 36 can guide the sliding of the movable seat 39, so that the movable seat 39 can move linearly in the vertical direction. The two groups of movable seats 39 are used to lift and support the extrusion tube 40. The extrusion tube 40 is in sliding contact with the outer surface of the elastic plate 41. The movable seat 39 and the extrusion tube 40 move upward under the elastic force of the traction rope 38. At this time, the extrusion tube 40 will apply a certain extrusion force to the elastic plate 41, so that the elastic plate 41 and the surface of the hardware 15 are kept in close contact, thereby improving the clamping effect of the hardware 15, which helps to further reduce the probability of the hardware 15 being offset during the drilling process.

[0041] like Figure 1 As shown, a drilling assembly is provided on the upper side of the support seat 11, and the drilling assembly includes a fixing frame 12 fixedly connected to the outer surface of the upper end of the support seat 11, and a displacement member 13 is provided on the outer surface of the right end of the fixing frame 12. The fixing frame 12 is movably connected to a drilling rig 14 through the displacement member 13, and the drilling rig 14 is located on the left side of the hardware 15.

[0042] By adopting the above technical solution, the support seat 11 lifts and supports the fixed frame 12, and the fixed frame 12 movably supports the drilling rig 14 through the movable displacement member 13. The movable member can drive the drilling rig 14 to move in the vertical direction, so that the height of the drilling rig 14 can be adjusted according to the position of the hardware 15. After the hardware 15 is clamped stably, the hardware 15 is drilled by the drilling rig 14. In the present application, the displacement member 13 and the drilling rig 14 both adopt the disclosed existing technology, so their specific working principles and structures are not described in detail here.

[0043] like Figure 2 and Figure 4 As shown, a limiting assembly is provided on the upper side of the support plate 17, and the limiting assembly includes a second connecting shaft 32 rotatably connected to the support plate 17, a positioning plate 34 is fixedly connected to the upper end of the second connecting shaft 32, and the outer surface of the positioning plate 34 is in rotational contact with the outer surface of the hardware 15, and a locking sleeve 33 is threadedly connected to the outer surface of the second connecting shaft 32, and the outer surface of the lower end of the locking sleeve 33 is in rotational contact with the upper end of the support plate 17, and the limiting assembly is used to limit the hardware 15 laterally.

[0044] By adopting the above technical scheme, the support plate 17 rotatably supports the second coupling shaft 32. After the hardware 15 is placed in place, the operator rotates the second coupling shaft 32, and the positioning plate 34 is driven to rotate synchronously through the second coupling shaft 32. At this time, the positioning plate 34 will contact the surface of the hardware 15, and the positioning plate 34 can play a blocking and limiting role on the hardware 15. When the drilling rig 14 drills the hardware 15, the positioning plate 34 can effectively reduce the deformation of the hardware 15, while ensuring the drilling accuracy, it also effectively improves the clamping stability of the hardware 15. After the drilling is completed, the positioning plate 34 is rotated 90 degrees. At this time, the positioning plate 34 will be out of contact with the hardware 15, so that the hardware 15 can be easily removed, and the locking sleeve 33 threadedly connected on the surface of the second coupling shaft 32 can cooperate with the support plate 17 to lock and fix the second coupling shaft 32, so that the second coupling shaft 32 can remain stable during the drilling process.

[0045] like Figure 2 , Figure 4 , Figure 7 , Figure 8 and Fig. 9 As shown, a driving assembly is provided at the lower end of the second connecting shaft 32, and the driving assembly includes a rotating wheel 31 fixedly connected to the lower end of the second connecting shaft 32, the rotating wheel 31 is in a circular ring shape, and the middle part of the inner surface of the rotating wheel 31 is rotatably connected to the connecting shaft 1 26, and the outer surface of the connecting shaft 1 26 is fixedly connected to a swing rod 43, and the lower side of the outer surface of the rotating wheel 31 is fixedly connected to a limiting rod 42, and the number of the limiting rods 42 is two groups, and the swing rod 43 is located between the two groups of limiting rods 42.

[0046] A turntable 27 is fixedly connected to the lower end of the connecting shaft 26, and a clamping block 28 is fixedly connected to the outer surface of the lower end of the turntable 27. The number of the clamping blocks 28 is several groups and distributed in a ring array. The outer surface of the upper end of the driving plate 30 is provided with a clamping groove 29. The number of the clamping grooves 29 is several groups and distributed in an arc shape. The clamping grooves 29 are in engagement with the clamping blocks 28. The driving component is used to drive the clamping component and the limit component to start operation.

[0047] By adopting the above technical solution, after the hardware 15 is placed inside the fixed cylinder 18, the operator rotates the rotating wheel 31, and the rotating wheel 31 drives the positioning plate 34 to rotate synchronously through the connecting shaft 2 32, so that the positioning plate 34 abuts against the outer surface of the hardware 15. As the rotating wheel 31 continues to rotate, the limiting rod 42 on the lower side of the rotating wheel 31 will contact the swing rod 43. At this time, the rotating wheel 31 drives the connecting shaft 1 26 to rotate synchronously through the limiting rod 42 and the swing rod 43. At this time, the connecting shaft 1 26 will drive the turntable 27 at its lower end to rotate synchronously, and drive the block 28 on the lower side to make a circular motion through the turntable 27. The block 28 will be sequentially engaged with the groove on the surface of the driving plate 30 during the rotation process. The inside of 29 can drive the driving plate 30 to make a circular motion through the engagement of the clamping block 28 and the clamping slot 29, and the support plate 19 can support the driving plate 30 for rotation. The rotation of the driving plate 30 can drive the clamping assembly to clamp and fix the hardware 15. After the drilling is completed, the operator rotates the rotating wheel 31 in the opposite direction, and the rotating wheel 31 drives the positioning plate 34 to rotate through the connecting shaft 2 32 so that the positioning plate 34 is out of contact with the anti-falling hardware 15. After the rotating wheel 31 rotates a certain angle, the connecting shaft 26 is driven to rotate through the swing rod 43 and the limit rod 42, and the driving plate 30 is driven to rotate in the opposite direction through the connecting shaft 26, thereby releasing the clamping and fixation of the hardware 15, so that the hardware 15 can be quickly removed.

[0048] like Figure 4 and Figure 6 As shown, the lower end of the hardware 15 is open, and the outer surface of the positioning plate 34 is provided with anti-skid grooves 35. The number of the anti-skid grooves 35 is several groups and distributed in an arc shape. The outer surface of the positioning plate 34 is in an arc shape, and the placement seat 20 is a hollow cone. The lower end of the hardware 15 is in contact with the outer surface of the placement seat 20.

[0049] The traction rope 38 is made of elastic material, the extrusion tube 40 is in a hollow ring shape, the extrusion plate 21 is made of wear-resistant insulating material, the extrusion plates 21 and the movable frames 22 are in several groups and are distributed in a ring shape on the outside of the hardware 15, and the guide groove 25 is located on the upper side of the guide groove 1 24.

[0050] By adopting the above technical scheme, the conical placement seat 20 can quickly position the lower end of the hardware 15, so that the center of the hardware 15 and the center of the fixed tube 18 remain coincident, which helps to improve the drilling accuracy of the hardware 15. The anti-slip groove 35 on the surface of the positioning plate 34 can effectively increase the friction between the positioning plate 34 and the hardware 15, thereby making the contact between the positioning plate 34 and the hardware 15 more firm. The hollow shape of the extrusion tube 40 can reduce the dead weight of the extrusion tube 40 to a certain extent, thereby reducing the pulling force of the extrusion tube 40 on the traction rope 38 to a certain extent.

[0051] Usage method: When drilling the cable anti-falling hardware 15, place the lower end of the hardware 15 inside the fixed tube 18. When the hardware 15 passes through the sleeve 36, its outer surface will slide and contact with the lower end of the elastic plate 41. The middle of the hardware 15 can be clamped by a plurality of groups of annularly distributed elastic plates 41. After the hardware 15 is placed in place, the operator rotates the rotating wheel 31, and the rotating wheel 31 drives the shaft 26 to rotate synchronously through the limit rod 42 and the swing rod 43. The shaft 26 drives the driving plate 30 to rotate through the turntable 27, and the driving plate 30 drives the guide rod 2 through the guide groove 25. 3 moves along the inside of the guide groove 1 24 toward the center of the driving plate 30, and the hardware 15 is clamped and fixed by a plurality of groups of extrusion plates 21 that are in contact with the outer surface of the hardware 15. The rotating wheel 31 drives the positioning plate 34 to rotate synchronously through the connecting shaft 2 32. The positioning plate 34 will contact the surface of the hardware 15. The positioning plate 34 can block and limit the hardware 15, which can effectively reduce the deformation of the hardware 15. While ensuring the drilling accuracy, it also effectively improves the clamping stability of the hardware 15. After the hardware 15 is clamped stably, the hardware 15 is drilled by the drilling machine 14.

[0052] The above is only a preferred specific implementation of the present invention; however, 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 solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
