Description

Technical Field

[0001] This invention relates to the field of power equipment technology, and in particular to a pin insertion device with multi-segment locking capability. Background Technology

[0002] To ensure the safe and stable operation of overhead transmission lines, pins must be installed on the hardware connecting components such as the ground wire to the tower, the conductor to the insulator, and the tower to the insulator in current transmission towers. These pins primarily serve a limiting function, mainly consisting of cotter pins and closed pins. They prevent nuts from falling off and ensure reliable hardware connections. Cotter pins and closed pins are simple in structure and easy to use. As key components for fixing hardware, if they fall off, it can easily lead to serious consequences such as conductor detachment and insulator string malfunction, severely threatening the power grid and personal safety. According to the regulations for the operation and maintenance management of overhead transmission lines, pin detachment defects are considered critical defects and must be addressed within 24 hours.

[0003] The process of re-inserting and locking new pins usually requires a power outage. Since power transmission lines are often connected to the power supply systems of surrounding villages and cities, a prolonged power outage can easily affect the daily power supply in the surrounding areas. Therefore, in some power transmission lines, the work needs to be carried out while the line is energized. However, the energized line puts a lot of pressure on the maintenance workers. Also, because the pins are small and the subsequent insertion position is small, it is easy to have to insert them multiple times before they can be successfully inserted when the line is energized. At the same time, under great pressure, there is a risk of electric shock, which poses a great safety hazard to personal safety.

[0004] This application designs a multi-segment locking pin insertion device to solve the above-mentioned defects. Summary of the Invention

[0005] In order to enable the rapid insertion of pins into the pin holes of bolts in a safe environment for quick positioning, this application provides a pin insertion device with multi-stage locking.

[0006] The multi-segment locking pin insertion device provided in this application adopts the following technical solution:

[0007] A multi-segment locking pin insertion device includes an adjusting rod that is rotatably connected to a connecting plate. An electric slider is provided at the left end of the connecting plate. The electric slider is connected to a connecting plate via a bracket. A rotatable sleeve assembly is provided on the connecting plate. An insertion assembly is installed on the sleeve assembly. The right end of the connecting plate is connected to a connecting sleeve via a connecting frame. A snap-fit ​​sleeve is rotatably provided inside the connecting sleeve.

[0008] The sleeve assembly includes an electric turntable, an extruder, an extrusion track, and an arc-shaped sleeve. The electric turntable is mounted on a connecting plate. Extruders are symmetrically mounted at the upper and lower ends of the electric turntable. The extruders are slidably connected to the extrusion track. The extrusion track is mounted on the outer wall of the arc-shaped sleeve, and the arc-shaped sleeves are arranged symmetrically front and back. The initial state of the arc-shaped sleeves arranged front and back is that they are separated from each other. Since the two ends of the pin will also be exposed after being inserted into the pin hole, the two ends of the pin will still be stuck in the sleeve assembly after the pin is inserted into the pin hole. In order to ensure that the sleeve assembly can be smoothly disengaged from the bolt, this application uses a combined openable arc-shaped sleeve to wrap the bolt in a sleeve-like manner. The opening and closing of the arc-shaped sleeves is controlled by the extrusion fit between the extruder and the extrusion track.

[0009] The insertion assembly includes an alignment component, a connecting frame, a clamping unit, an engagement unit, a straightening layer, a multi-stage cylinder, a power supply unit, and a fixed slide. The alignment component is mounted on an arc-shaped sleeve located at the rear, and the connecting frame is mounted on an arc-shaped sleeve located at the front. The upper end of the connecting frame has an open structure, and the open structure is connected to a cover plate via a hinge. The open structure facilitates the insertion of the pin. The fixed slide, which is slidably connected to the connecting frame, has clamping units symmetrically arranged at its left and right ends. Engaging units engage between the clamping units. A multi-stage cylinder is connected between the engaging units and the insulating shell located on the connecting frame. The multi-stage cylinder is electrically connected to the power supply unit located below the connecting frame. The straightening layer, which cooperates with the clamping unit, is installed on the inner wall of the connecting frame. The clamping unit, engagement unit, straightening layer, and multi-stage cylinder cooperate to simulate the pressure applied to the pin by a person, so that the pin is in a closed state before entering the pin hole, thereby ensuring the smooth insertion of the pin.

[0010] This application provides an emergency remedy for the phenomenon of power transmission line pins falling off, and the remedy does not require power outage, which greatly improves the remedy efficiency.

[0011] As a preferred embodiment of the present invention, the extrusion component includes a connecting rod and an extrusion rod. The connecting rod is mounted on an electric turntable, and the extrusion rods are symmetrically mounted at the front and rear ends of the connecting rod. The outer side of the extrusion rod is slidably disposed in an inclined groove opened in the extrusion track, and the inclined groove has a structure that gradually slopes outward from left to right.

[0012] As a preferred embodiment of the present invention, the alignment component includes a fixed sleeve, a built-in spring, and an alignment head. The fixed sleeve is mounted on the arc-shaped sleeve, and the built-in spring connects the inside of the fixed sleeve and the alignment head, with the built-in spring serving as an elastic connection.

[0013] As a preferred embodiment of the present invention, the spherical structure of the alignment head is uniformly provided with rollable drag-reducing beads, which reduce the resistance when in contact with the surface of the bolt thread structure.

[0014] As a preferred embodiment of the present invention, the clamping unit includes a first gear, a second gear, a rotating rod, and a clamping member. The first gear is rotatably disposed in an insulating shell, and the second gear, which meshes with the first gear, is mounted on a rotating shaft. The rotating shaft and the insulating shell are connected by a bearing. A rotating rod is connected between the rotating shaft and the clamping member. An insulating clamping member is installed at the rear end of the rotating rod. The clamping member in its initial position rests against the front inclined surface of the straightening layer, and the rear end of the rotating rod in its initial position rests against the front end of the straightening layer. This ensures that the rotating rod can only move backward after moving towards each other to the minimum angle. Furthermore, due to the outer limit of the straightening layer, the angle of the rotating rod remains unchanged during the backward movement. The inner end face of the clamping member is provided with an inwardly concave arc-shaped groove, which improves the fit with the circular cross-section pin.

[0015] As a preferred embodiment of the present invention, the meshing unit includes a fixed rod, a rack, a T-shaped piece, and a connecting spring. The extended end of the multi-stage cylinder is equipped with a fixed rod, and the rack connected to the side wall of the fixed rod meshes with a gear. A T-shaped piece is slidably arranged inside the fixed rod, and a connecting spring is connected between the fixed rod and the T-shaped piece fixedly arranged on the fixed sliding piece. The connecting spring plays the role of elastic connection.

[0016] As a preferred embodiment of the present invention, the power supply unit is electrically connected to the power source, the starting component, and the multi-stage cylinder. The switch of the starting component is exposed outside the arc-shaped sleeve. After the arc-shaped sleeve is closed, the switch of the starting component is pressed. At this time, a closed circuit is formed between the starting component, the power source, and the multi-stage cylinder. The multi-stage cylinder is energized and begins to move the fixed rod, which then clamps the pin. During the period of clamping the pin, the electric turntable drives the closed arc-shaped sleeve to rotate rapidly until the alignment component is embedded in the pin hole, thereby determining the insertion position. Then, the multi-stage cylinder inserts the closed pin into the pin hole.

[0017] As a preferred embodiment of the present invention, a fixing post is provided in the middle of the fixing slide, the fixing post is used to fit a fixing pin, and the middle part of the rotating rod is slidably disposed in the arc-shaped groove opened in the fixing slide, thereby improving the stability of the rotation of the rotating rod.

[0018] As a preferred embodiment of the present invention, the cross-section of the inner cavity of the snap-fit ​​sleeve is hexagonal, and the left end of the inner cavity is flared. The rotational connection between the connecting sleeve and the snap-fit ​​sleeve and the opening of the flared structure are all for the purpose of allowing the snap-fit ​​sleeve to be quickly fitted onto the head of the bolt.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. The present invention provides a multi-segment locking pin insertion device. This application determines the pin insertion point by determining the position of the bolt and pin hole, eliminating the need for personnel to inspect closely with the naked eye. After the position is determined, the mechanical structure simulates the action of personnel pressing and inserting the pin. The pin is accurately inserted into the pin hole through a multi-segment position locking method, which greatly improves the insertion efficiency. During the entire insertion process, personnel only need to align the device with the bolt position to control it from a distance, thereby quickly inserting the pin. The risk of electric shock is greatly reduced, and the maintenance pressure is also greatly relieved.

[0021] 2. The multi-segment locking pin insertion device of the present invention, since the sleeve component and the insertion component are on the same axis, the sleeve component and the bolt head are fitted together, so that the insertion component and the tail (thread structure) of the bolt are aligned, ensuring the positional alignment accuracy between the present invention and the bolt, eliminating the need for close-range alignment by personnel, and by inserting the pin into the present invention for alignment and insertion, the risk of electric shock is greatly reduced compared to close-range insertion by personnel.

[0022] 3. The multi-segment locking pin insertion device of the present invention has an arc sleeve that is detachable and can be combined. When the pin is successfully inserted into the pin hole and the present invention needs to be removed from the bolt position, the movement trajectory of the arc sleeve is to first separate from each other and then move horizontally to remove it, thus avoiding the situation of untimely removal.

[0023] 4. The multi-segment locking pin insertion device of the present invention adopts the design concept of structural linkage. After the pin is positioned, it is pressed on both sides to form a closed state, and then pushed into the pin hole for position locking, so as to make timely correction. Attached Figure Description

[0035] Embodiments of the present invention will now be described with reference to the accompanying drawings. In this process, to ensure clarity and convenience of explanation, we may exaggerate the width of lines or the size of constituent elements in the drawings.

[0036] Furthermore, the terms used below are defined based on the functionality of this invention and may vary depending on the user's, operator's, or conventions. Therefore, these terms are defined based on the entire contents of this specification.

[0037] like Figures 1 to 10 As shown, a multi-segment locking pin insertion device includes an adjusting rod 1, which is rotatably connected to a connecting plate 2. An electric slider is provided at the left end of the connecting plate 2, and the electric slider is connected to a connecting disk 3 via a bracket. A rotatable sleeve assembly 4 is provided on the connecting disk 3, and an insertion assembly 5 is installed on the sleeve assembly 4. The right end of the connecting plate 2 is connected to a connecting sleeve 6 via a connecting frame, and a snap-fit ​​sleeve 7 is rotatably provided inside the connecting sleeve 6.

[0038] The sleeve assembly 4 includes an electric turntable 41, an extruder 42, an extrusion track 43, and an arc-shaped sleeve 44. The electric turntable 41 is mounted on the connecting plate 3. The extruder 42 is symmetrically mounted on the upper and lower ends of the electric turntable 41. The extruder 42 is slidably connected to the extrusion track 43. The extrusion track 43 is mounted on the outer wall of the arc-shaped sleeve 44, and the arc-shaped sleeve 44 is arranged symmetrically front and back. The initial state of the arc-shaped sleeves 44 arranged front and back is that they are separated from each other. Since the two ends of the pin will also be exposed after the pin is inserted into the pin hole, the two ends of the pin will still be stuck in the sleeve assembly 4 after the pin is inserted into the pin hole. In order to ensure that the sleeve assembly 4 can be smoothly disengaged from the bolt 8, the bolt 8 is wrapped in a sleeve-like manner by a combined openable arc-shaped sleeve 44. The opening and closing of the arc-shaped sleeves 44 is controlled by the extrusion fit between the extruder 42 and the extrusion track 43.

[0039] The insertion assembly 5 includes an alignment member 51, a connecting frame 52, a clamping unit 53, an engagement unit 54, a straightening layer 55, a multi-stage cylinder 56, a power supply unit 57, and a fixing slide member 58. The alignment member 51 is mounted on the arc-shaped sleeve 44 located on the rear side, and the connecting frame 52 is mounted on the arc-shaped sleeve 44 located on the front side. The upper end of the connecting frame 52 has an open structure, and the open structure is connected to a cover plate by a hinge. The design of the open structure facilitates the insertion of the pin. The fixing slide member 58, which is slidably connected to the connecting frame 52, has clamping units 54 symmetrically arranged at its left and right ends. 3. The clamping units 53 are engaged with a meshing unit 54. The meshing unit 54 is connected to the insulating shell on the connecting frame 52 by a multi-stage cylinder 56. The multi-stage cylinder 56 is electrically connected to the power supply unit 57 located below the connecting frame 52. The straightening layer 55, which cooperates with the clamping unit 53, is installed on the inner side wall of the connecting frame 52. The clamping unit 53, the meshing unit 54, the straightening layer 55, and the multi-stage cylinder 56 cooperate to simulate the pressure of a person on the pin, so that the pin is in a closed state before entering the pin hole, thereby ensuring the smooth insertion of the pin.

[0040] Specifically, the pin is fastened into the fixed slide 58, and then the snap-fit ​​sleeve 7 is aligned with the head of the bolt 8 and fitted, thereby determining the position between the fitting assembly 4, the insertion assembly 5 and the bolt 8. Then, the connecting plate 2 is moved by the electric slider (the fitting assembly 4 and the insertion assembly 5 move synchronously). During the movement, the arc-shaped sleeve 44 first contacts the side of the suspension clamp 9. At this time, the remaining parts of the fitting assembly 4 continue to move, and the arc-shaped sleeve 44 is merged by the pressing cooperation between the pressing part 42 and the pressing track 43 to form a sleeve structure. At this time, the connecting plate 2 is stopped by the electric slider, and then the merged sleeve structure is rotated by the electric turntable 41 until the alignment part 51 is aligned. The pin stops rotating only after it is inserted into the pin hole. At this time, the multi-stage cylinder 56 drives the meshing unit 54 to move backward, cooperating with the clamping unit 53 to clamp both ends of the pin, so that the pin is clamped from a forked type to a merged type. Then, the fixed slide 58 pushes the merged pin into the pin hole of the bolt 8, thereby limiting the position of the nut 10 on the bolt 8 and preventing it from loosening and falling off. Then, the electric slider drives the connecting plate 2 to move in the opposite direction, and the merged arc sleeves 44 gradually open and then move accordingly until they return to the initial state. This application provides an emergency remedy for the phenomenon of pins falling off in transmission lines, and there is no need to cut off the power during the remedy process, which greatly improves the remedy efficiency.

[0041] In another embodiment of the present invention, the extrusion member 42 further includes a connecting rod 421 and an extrusion rod 422. The connecting rod 421 is mounted on the electric turntable 41, and the extrusion rods 422 are symmetrically mounted at the front and rear ends of the connecting rod 421. The outer side of the extrusion rod 422 is slidably disposed in the inclined groove opened in the extrusion track 43, and the inclined groove has a structure that gradually slopes outward from left to right.

[0042] Specifically, the connecting plate 2 is moved by an electric slider (the sleeve assembly 4 and the insertion assembly 5 move synchronously). During the movement, the separated arc sleeves 44 first contact the side of the suspension clamp 9 and stop moving after encountering resistance. At this time, the remaining parts of the sleeve assembly 4 continue to move, and the arc sleeves 44 arranged in front and behind gradually merge to form a sleeve structure through the squeezing cooperation between the squeezing rod 422 and the squeezing track 43. Then, the pin insertion operation is carried out. After the insertion is completed, the exposed parts of the two ends of the pin that have entered the pin hole are inserted into the inside of the arc sleeve 44 (at this time, the merged arc sleeve 44 cannot fall off smoothly). The connecting plate 2 is moved in the opposite direction by the electric slider. During the reverse movement, the squeezing component 42 moves directly with it, but the arc sleeve 44 cannot move directly with the connecting plate 2 due to the locking of the pin end. Instead, the merged arc sleeve 44 gradually separates under the squeezing cooperation between the squeezing rod 422 and the squeezing track 43. When it separates to the initial state, the end of the pin is removed from the inside of the arc sleeve 44, and the arc sleeve 44 moves with the connecting plate 2.

[0043] Furthermore, the alignment member 51 includes a fixing sleeve 511, a built-in spring 512, and an alignment head 513. The fixing sleeve 511 is mounted on the arc-shaped sleeve 44. The built-in spring 512 is connected between the inside of the fixing sleeve 511 and the alignment head 513. The built-in spring 512 plays the role of elastic connection. Rollable drag-reducing beads are evenly arranged on the spherical structure of the alignment head 513. The arrangement of the drag-reducing beads reduces the resistance when in contact with the threaded structure surface of the bolt 8.

[0044] Specifically, after the arc-shaped sleeve 44 is combined to form a sleeve structure, it is driven to rotate by the electric turntable 41 until the alignment head 513 is inserted into one end of the pin hole, at which point the position of the subsequent pin insertion is determined.

[0045] Furthermore, the clamping unit 53 includes a first gear 531, a second gear 532, a rotating rod 533, and a clamping member 534. The first gear 531 is rotatably mounted in the insulating shell. The second gear 532, which meshes with the first gear 531, is mounted on a rotating shaft. The rotating shaft and the insulating shell are connected by a bearing. The rotating rod 533 is connected between the rotating shaft and the clamping member 534. The clamping member 534, made of insulating material, is installed at the rear end of the rotating rod 533. The clamping member 534 in the initial position abuts against the front inclined surface of the straightening layer 55, and the rear end of the rotating rod 533 in the initial position abuts against the front end of the straightening layer 55. This ensures that the rotating rod 533 can only move backward after moving towards each other to the minimum angle. Moreover, due to the outer limit of the straightening layer 55, the angle of the rotating rod 533 remains unchanged during the backward movement. The inner end face of the clamping member 534 is provided with a concave arc groove, which improves the fit with the circular cross-section pin.

[0046] Furthermore, the meshing unit 54 includes a fixed rod 541, a rack 542, a T-shaped piece 543, and a connecting spring 544. The extended end of the multi-stage cylinder 56 is equipped with a fixed rod 541. The rack 542, which is connected to the side wall of the fixed rod 541, meshes with the gear 531. The T-shaped piece 543 is slidably arranged inside the fixed rod 541. A connecting spring 544 connects the fixed rod 541 and the T-shaped piece 543, which is fixedly arranged on the fixed slide 58. The connecting spring 544 plays the role of elastic connection.

[0047] Specifically, the multi-stage cylinder 56 drives the fixed rod 541 to move backward. Under the meshing engagement of the rack 542, gear one 531, and gear two 532, the rotating rods 533 on both sides rotate towards each other until the clamping member 534 clamps the pin, making it close (because when the clamping member 534 does not clamp the pin, the rear end of the rotating rod 533 will abut against the front end of the straightening layer 55. Therefore, only after the rotating rods 533 move towards each other to the minimum angle will the rotating rods 533 be free from the limitation of the straightening layer). At this time, the fixed rod 541 also just abuts against the T-shaped member 543, and then drives the fixed slide member 58 to move backward together, thereby pushing the closed pin backward until it is inserted into the pin hole (during the backward movement of the fixed slide member 58, due to the limitation of the straightening layer 55 on the outside of the rotating rod 533, the pin is always in the closed state). When 58 is about to move to the last side, the straightening layer 55 no longer limits the outer side of the rotating rod 533. Under the action of the connecting spring 544, the fixed slide 58 moves backward a small distance relative to the fixed rod 541 (at this time, the pin is fully inserted into the pin hole), causing the rotating rod 533 to unfold outward. The clamping member 534 no longer clamps the pin. The overall movement trajectory of the clamping unit 53 is as follows: first, the pin is clamped by adjusting the opposite angle of the rotating rod 533, and then the clamped pin is pushed into the pin hole. Before it is fully pushed in, the rotating rod 533 is adjusted to the outside angle to reset, and the pin that is about to be fully pushed in is finally inserted with the help of the connecting spring 544. At this time, the rotating rod 533, which is adjusted to the outside angle, causes the clamping member 534 to no longer clamp the pin, ensuring the smooth separation between the sleeve assembly 4 and the bolt 8.

[0048] Furthermore, the power supply unit 57 is electrically connected to the power source, the starter 59, and the multi-stage cylinder 56. The switch of the starter 59 is exposed outside the arc-shaped sleeve 44. After the arc-shaped sleeve 44 is closed, the switch of the starter 59 is pressed. At this time, a closed circuit is formed between the starter 59, the power source, and the multi-stage cylinder 56. The multi-stage cylinder 56 is energized and begins to move the fixing rod 541, which then clamps the pin. During the period of clamping the pin, the electric turntable 41 drives the closed arc-shaped sleeve 44 to rotate rapidly until the alignment member 51 is embedded in the pin hole, thereby determining the insertion position. Then, the multi-stage cylinder 56 inserts the closed pin into the pin hole.

[0049] Furthermore, a fixing post 60 is provided in the middle of the fixing slide 58, which is used to fit a fixing pin. The middle part of the rotating rod 533 is slidably arranged in the arc-shaped groove opened in the fixing slide 58, which improves the stability of the rotation of the rotating rod 533. The cross-section of the inner cavity of the snap-fit ​​sleeve 7 is a hexagonal structure, and the left end of the inner cavity is a flared structure. The rotational connection between the connecting sleeve 6 and the snap-fit ​​sleeve 7 and the opening of the flared structure are all to allow the snap-fit ​​sleeve 7 to be quickly fitted onto the head of the bolt 8.

[0050] Work process:

[0051] Step 1, Preparatory work: Place the pin on the fixing post 60;

[0052] Step 2: Determine the position: Personnel climb to the designated position to find the remedial position, and align the snap-fit ​​sleeve 7 with the head of the bolt 8 to determine the position between the sleeve component 4, the insertion component 5 and the bolt 8.

[0053] Step 3, Merging and Fitting: The connecting plate 2, the fitting component 4, and the insertion component 5 are moved synchronously by the electric slider. During the movement, the separate arc-shaped sleeves 44 gradually merge and fit onto the threaded structure of the bolt 8.

[0054] Step 4, Insertion: The electric turntable 41 drives the combined sleeve structure to rotate until the alignment part 51 is inserted into the pin hole and then stops rotating. At this time, the multi-stage cylinder 56 drives the meshing unit 54 to move backward, cooperating with the clamping unit 53 to clamp and close the pin. After closing, the movement of the fixed slide 58 causes the combined pin to be inserted into the pin hole, thereby limiting the position of the nut 10 on the bolt 8.

[0055] Step 5, Reset: After the pins are inserted, the connecting plate 2 is moved in the opposite direction by the electric slider. The merged arc sleeves 44 gradually open and then move together until they return to the initial state.

[0056] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
