Description

Technical Field

[0001] This invention belongs to the field of auxiliary technology for suspension clamp installation equipment, and particularly relates to a suspension clamp pre-assembly device. Background Technology

[0002] like Figure 1 The suspension clamp shown is used in overhead power lines or substations to suspend conductors or lightning protection wires from insulator strings or directly fix them to poles and towers. Its main function is to bear vertical loads to ensure the stability and safety of the conductors in different environments. Before the suspension clamp is delivered to the construction site, it needs to be pre-assembled. Since the installation of suspension clamps is mostly done at heights, it is inconvenient to assemble them on-site. Therefore, the suspension clamp is usually pre-assembled in the factory, leaving a gap between the suspension clamp body and the locking block. During construction, the conductor is inserted, and finally the nut at the connection between the locking block and the suspension clamp body is tightened to complete the installation.

[0003] Most existing methods for assembling suspension clamps involve manual pre-assembly. In these methods, the clamp body, locking block, nut, and other components are placed in separate storage boxes. These boxes are then placed on a workbench. Workers remove the clamp body from the boxes, insert the screw at the bottom of the locking block into the corresponding hole in the clamp, and finally use an electric nut tightening machine to screw the nut into the corresponding screw. This improves assembly efficiency, but this method can only connect one locking block and nut at a time, so efficiency still needs improvement. Summary of the Invention

[0004] To address the shortcomings of the existing technology, this invention provides a pre-assembly device for suspension clamps, which can assemble two locking blocks simultaneously, improving work efficiency and reducing costs.

[0005] In order to achieve the objective of this invention, the following solution is proposed:

[0006] A pre-assembly device for a suspension clamp includes an assembly component and a clamping component. The assembly component includes a base with a material tube frame spanning it for placing nuts. One side of the lower end of the material tube frame has a push-out component, and the other side has a U-shaped seat with an opening facing the material tube frame. An assembly frame is provided on the U-shaped seat. A set of clearance holes are spaced apart on one side of the bottom of the assembly frame and arranged symmetrically along the long axis of the base. The lower end of the clearance holes vertically penetrates the base. The base has a hexagonal blind hole coaxial with the clearance holes for accommodating nuts. One end of the assembly frame has a first conveyor belt with a conveying direction perpendicular to the length direction of the base for conveying locking blocks. A second conveyor belt is vertically provided at the end of the first conveyor belt with a conveying direction for conveying clamping bodies, and the end of the second conveyor belt with a conveying direction is connected to the assembly frame. A locking block picking component is vertically provided at the midpoint of the line connecting the end of the first conveyor belt with the clearance holes. The component includes a telescopic rod vertically rotatably mounted on the base. The upper end of the telescopic rod has a cantilever, and the bottom surface of the cantilever has a set of clamping seats for clamping the locking blocks.

[0007] The clamping assembly includes a gear coaxially mounted at the lower end of the telescopic rod. The gear meshes with a rack. One end of the rack is vertically connected to a horizontal plate parallel to the length direction of the base. The other end of the horizontal plate has a T-shaped plate arranged vertically. The vertical part of the T-shaped plate passes through the assembly frame, and its horizontal part slides in cooperation with the bottom surface inside the assembly frame to push the conveyed clamping body above the clearance hole.

[0008] Furthermore, the distance between the bottom outlet of the material tube rack and the top surface of the base is greater than the height of a nut, and the depth of the hexagonal blind hole is consistent with the height of the nut.

[0009] Furthermore, a strip platform is vertically provided at one end of the assembly frame, and a telescopic rod passes through the strip platform. Three first conveyor belts are provided in parallel and spaced apart, and a conveying area is formed between two adjacent first conveyor belts for conveying lock blocks.

[0010] Furthermore, the ejector includes a push plate, which has an inverted L-shaped structure. A first cylinder is provided on one side of the horizontal part of the push plate, and the vertical part is located above the first cylinder. The first cylinder is installed on the other end of the base. A sliding groove is provided on the opposite side of the two arms of the U-shaped base. One end of the sliding groove extends to the material tube frame. Protrusions that are slidably connected to the sliding groove are provided on both sides of the horizontal part of the push plate.

[0011] Furthermore, the assembly frame has a recessed groove on one side connected to the second conveyor belt to accommodate the horizontal part of the T-shaped plate, and an L-shaped guide groove runs through the bottom of the assembly frame. The upper end of its vertical part is connected to the accommodating groove, and the vertical part of the T-shaped plate slides in conjunction with the guide groove.

[0012] Furthermore, the second conveyor belt has side plates on both sides, and the side plates have notches at the joints with the assembly frame. One end of the T-shaped plate has a vertical stop bar, and one end of the stop bar passes through the notch.

[0013] Furthermore, a guide cylinder is vertically provided on the strip platform, and the guide cylinder is coaxially provided outside the telescopic rod. An arc-shaped groove is provided on the cross-section of the guide cylinder, and a limiting pin is vertically provided outside the telescopic rod. The limiting pin slides in conjunction with the arc-shaped groove.

[0014] Furthermore, stepped holes are provided on both sides of the clamping seat, and guide pins are inserted into the stepped holes. Springs are fitted over the guide pins, and the two ends of the springs abut against the guide pins and the stepped holes, respectively.

[0015] Furthermore, the guide pin has a rectangular cross-section, with circular plates at both ends, and the bottom surface of the circular plates located in the clamping seat has an inclined surface.

[0016] Furthermore, a second cylinder is provided in the middle of one side of the horizontal plate, and the second cylinder is installed at the bottom of the assembly frame.

[0017] The beneficial effects of this invention are as follows:

[0018] The second cylinder pushes the horizontal plate to move, which in turn drives the rack to move, so that the clamping seat rotates the lock block onto the assembly frame. At the same time as the horizontal plate moves, the T-shaped plate pushes the clamping body and limits its position. Then, the telescopic rod shortens vertically downward, so that the screw at the lower end of the lock block is inserted vertically downward into the corresponding round hole in the clamping body. The clamping seat is rotated, so that the screw and nut are threaded together, thereby realizing the synchronous assembly of the two lock blocks, improving work efficiency and saving labor costs.

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention will be described in detail below with reference to the accompanying drawings. However, the embodiments described in this invention are only some embodiments of the present invention, and not all embodiments.

[0032] like Figures 2-10 As shown, this embodiment provides a pre-assembly device for suspension clamps, including an assembly assembly 10 and a clamping body assembly 20, for use in assembling, for example, a suspension clamp. Figure 1 The suspension clamp shown is pre-assembled. The suspension clamp includes a clamp body 1, two locking blocks 2, and two nuts 3. The clamp body 1 has a long strip structure. The top surface has mounting slots on both sides along its length. There is a plane between the two mounting slots. There are round holes at both ends of the plane. The upper end of the locking block 2 has a protrusion. The top surface of the protrusion has an arc structure, and the two sides have a plane structure. There are mounting slots corresponding to the mounting slots on the clamp body 1 below the arc of the protrusion. During assembly, the mounting slots on the clamp body 1 correspond to the mounting slots on the locking block 2 and are used to wrap around the outer wall of the guide. The screw at the lower end of the protrusion passes through the round hole of the clamp body 1 and is locked by the nuts 3, thereby fixing the wire.

[0033] Specifically, such as Figures 2-5As shown, the assembly component 10 includes a base 11, a material tube frame 12, a U-shaped seat 13, an ejector 14, an assembly frame 15, a strip platform 16, a first conveyor belt 17, a second conveyor belt 18, and a locking block material handling component 19. The base 11 has a rectangular platform structure and is fixedly connected to a frame. The top surface of the base 11 has two spaced hexagonal blind holes 111, and the center distance between the two hexagonal blind holes 111 is the same as the center distance between the circular holes on the clamp 1.

[0034] The material tube rack 12 spans the top surface of the base 11 and is located on one side of the hexagonal blind hole 111. Two material tubes are vertically provided on the material tube rack 12 for storing nuts 3. The inner wall shape of the cross-section of the material tube is adapted to the outer shape of the nut 3. The distance between the material tube rack 12 bottom outlet and the top surface of the base 11 is greater than the height of one nut 3 and less than the sum of the heights of two nuts 3.

[0035] The U-shaped seat 13 is horizontally mounted on the base 11. The length direction of the U-shaped seat 13 is consistent with the length direction of the base 11. The two side arms of the U-shaped seat 13 are located on both sides of the hexagonal blind hole 111. The U-shaped seat 13 is located on one side of the material tube frame 12. The opening of the U-shaped seat 13 faces the material tube frame 12. The distance between the two inner walls of the U-shaped seat 13 is consistent with the distance between the two side walls of the lower end of the material tube frame 12. The two side arms of the U-shaped seat 13 are respectively recessed on opposite sides. The end of the sliding groove 131 facing the material tube frame 12 extends to the two side walls of the material tube frame 12's outlet.

[0036] Preferably, in order to ensure that the nut 3 can fall accurately into the corresponding hexagonal blind hole 111, the distance between the two arms of the U-shaped seat 13 is adapted to the length dimension of the nut 3, and one set of symmetrical outer walls of the nut 3 falls out of the material tube of the material tube frame 12 parallel to the two side arms of the U-shaped groove 13.

[0037] The ejector 14 is mounted on the base 11 and located on the other side of the tube frame 12. The output end of the ejector 14 faces the direction of the tube frame 12, and the two ends of the ejector 14 in the output direction are slidably connected to the slide groove 131 respectively, for pushing the nut 3 in the tube frame 12 into the corresponding hexagonal blind hole 111 in the base 11.

[0038] Specifically, the ejector 14 includes a push plate 141 and a first cylinder 142. The push plate 141 has an inverted L-shaped structure, with protrusions on both sides of the horizontal portion of the push plate 141. The protrusions slide in cooperation with the corresponding grooves 131. The first cylinder 142 is installed on one side of the material tube frame 12 of the base 11, and the output end of the first cylinder 142 is connected to the middle of one side of the horizontal portion of the push plate 141. Normally, the cylinder body of the first cylinder 142 is located below the push plate 141. When the first cylinder 142 pushes the push plate 141 to move along the groove 131, the horizontal portion of the push plate 141 is used to push the two nuts 3 at the outlet of the material tube frame 12 into the corresponding hexagonal blind holes 111 along the length of the base 11. The vertical portion of the push plate 141 is used to close the outlet of the material tube frame 12.

[0039] like Figure 4 , Figure 7 As shown, the assembly frame 15 is located on the top surface of the U-shaped base 13. The bottom surface of the assembly frame 15 is a rectangular plate structure, and the top is provided with a U-shaped surrounding plate. The opening direction of the surrounding plate is opposite to the opening direction of the U-shaped base 13. The horizontal part of the surrounding plate abuts against one side of the material tube frame 12. The bottom surface of the assembly frame 15 is provided with two clearance holes 151 at intervals. The clearance holes 151 and the hexagonal blind holes 111 are coaxially arranged one by one, and the lower end of the clearance holes 151 vertically penetrates the bottom surface of the base 11. The diameter of the clearance holes 151 is larger than the diameter of the outer circle of the nut 3. A guide groove 152 is provided perpendicular to the line connecting the centers of the two clearance holes 151. The guide groove 152 is an L-shaped structure. Its vertical part connects vertically upward to the outer support arm of the surrounding plate, and a receiving groove communicating with the guide groove 152 is recessed in the outer support arm of the surrounding plate.

[0040] The strip platform 16 is set perpendicular to one end of the opening of the enclosure. Three first conveyor belts 17 are arranged in parallel and spaced apart, and are located on the side of the top surface of the strip platform 16 away from the enclosure. A conveying area is formed between two adjacent first conveyor belts 17 for conveying the lock block 2. The center distance between the two conveying areas is the same as the center distance between the two hexagonal blind holes 111. During conveying, the end of the lock block 2 with the screw is downward and the end with the block is respectively located on the first conveyor belt 17 for conveying. The ends of the three first conveyor belts 17 in the conveying direction are collinear with the direction of the line connecting the centers of the two clearance holes 151.

[0041] The second conveyor belt 18 is used to transport the clamp 1, and the second conveyor belt 18 is set in the direction of the opening of the surrounding plate. The length direction of the second conveyor belt 18 is consistent with the length direction of the two side arms of the surrounding plate. There are guard plates on both sides of the second conveyor belt 18. The distance between the two guard plates is adapted to the width of the clamp 1. The outer guard plate is flush with the outer side arm of the surrounding plate, and there is a notch 181 between the outer guard plate and the outer side arm of the surrounding plate. One end of the receiving groove is connected to the notch 181. The inner guard plate is perpendicularly connected to one end of the strip platform 16. After the clamp 1 passes through the output end of the second conveyor belt 18, it enters the assembly frame 15 along the opening direction of the surrounding plate. The distance between the inner wall of the horizontal part of the surrounding plate and the strip 16 is consistent with the length of the clamp 1.

[0042] like Figure 4 , Figure 7 As shown, the locking block material pick-up component 19 is rotatably connected to the base 11 and located on one side of the horizontal part of the U-shaped seat 13. The locking block material pick-up component 19 includes a telescopic rod 191, a cantilever 192, a clamping seat 193, a stepped hole 194, a limiting pin 196, and a spring 197. The lower end of the telescopic rod 191 is rotatably connected to the base 11, and the upper end of the telescopic rod 191 passes vertically upward through the strip platform 16. The axis of the telescopic rod 191 is vertically located at the midpoint where the end of the first conveyor belt 17 in the conveying direction is connected to the clearance hole 151.

[0043] A cantilever 192 is vertically mounted on the upper end of the telescopic rod 191. Two clamping seats 193 are spaced apart, with the center distance between the two clamping seats 193 matching the center distance between the two clearance holes 151. The distance from the center of each clamping seat 193 to the axis of the telescopic rod 191 is equal to the distance from the clearance hole 151 to the support of the axis of the telescopic rod 191. A rotary motor with its output end pointing vertically downwards is mounted on the upper end of each clamping seat 193. The housing of the rotary motor is connected to the cantilever 192, allowing the rotary motor to drive the clamping seat 193 to rotate around its own axis. Stepped holes 194 are located on both sides of the clamping seat 193, with the axial direction of the stepped holes 194 aligned with the length direction of the cantilever 192. The larger end of the stepped hole 194 faces inwards towards the clamping seat 193, and the cross-section of the stepped hole 194 has a directional structure, such as... Figure 9 As shown, a limiting pin 196 is coaxially inserted in the stepped hole 194. The cross-section of the limiting pin 196 is adapted to the cross-sectional dimensions of the stepped hole 194. Limiting plates are provided at both ends of the limiting pin 196. The bottom surface of one of the limiting plates located in the stepped hole 194 is provided with an inclined surface, and the lower end of the inclined surface is inclined in the direction of the stepped hole 194. The upper end is connected to the side of the limiting plate facing the clamping seat 193.

[0044] Spring 197 is inserted through limit pin 196, and one end of spring 197 abuts against one side of the stepped hole 194 where the large end and small end meet, and the other end abuts against the other side of the limit pin 196 facing the limit plate inside the clamping seat 193.

[0045] like Figures 2-6 As shown, the clamping assembly 20 includes a gear 21, a rack 22, a horizontal plate 23, a T-shaped plate 24, a limiting strip 25, and a second cylinder 26. The gear 21 adopts an incomplete tooth structure, with the meshing teeth on the gear 21 distributed at an angle greater than 180°. The gear 21 is coaxially fixed to the lower end of the telescopic rod 191. The rack 22 is slidably disposed along the horizontal part of the U-shaped seat 13 and meshes with the gear 21. The number of teeth of the rack 22 matches the number of teeth of the gear 21 to ensure that the gear 21 and the rack 22 are always in a meshing state, avoiding impact that would occur if the gear 21 and the rack 22 disengage and then re-engage, thus affecting the service life of the gear 21 or the rack 22.

[0046] One end of the horizontal plate 23 is perpendicularly connected to one end of the rack 22, and the other end of the horizontal plate 23 extends toward the bottom surface of the assembly frame 15. The T-shaped plate 24 is arranged vertically, and the vertical part of the T-shaped plate 24 is vertically downward and perpendicularly connected to the other end of the horizontal plate 23. The length of the horizontal part of the T-shaped plate 24 is less than the length of the receiving groove. The upper end of the vertical part of the T-shaped plate 24 passes vertically upward into the assembly frame 15 along the guide groove 152. The horizontal part of the T-shaped plate 24 is parallel to the side arms of the surrounding plate. The limiting strip 25 is vertically set at one end of the horizontal part of the T-shaped plate 24 facing the direction of the strip platform 16, and is used to intercept the next clamp 1 from entering the assembly frame 15. One end of the limiting strip 25 corresponds to the notch groove 181. The second cylinder 26 is set on the bottom surface of the outer wall of the assembly frame 15, and the output end of the second cylinder 26 is perpendicularly connected to the midpoint of the length direction of the horizontal plate 23.

[0047] After the clamp 1 is conveyed to the assembly frame 15 along the second conveyor belt 18, the second cylinder 26 is activated, causing the second cylinder 26 to push the horizontal plate 23 closer to the base 11. At this time, the horizontal plate 23 pushes the rack 22 to move along the direction of the feed port of the first conveyor belt 17 perpendicular to the length direction of the base 11, thereby causing the rack 22 to drive the gear 21 to rotate, and the telescopic rod 191 to rotate synchronously under the rotation of the gear 21. On the other hand, the horizontal plate 23 drives the T-shaped plate 24 to move along the guide groove 152, thereby causing the T-shaped plate 24 to move the clamp 1 that has entered the assembly frame 15 closer to the inner support arm of the surrounding plate, until the two sides of the clamp 1 abut against the inner support arm of the surrounding plate and the horizontal part of the T-shaped plate 24 respectively, so as to achieve the positioning of the clamp 1.

[0048] like Figure 4 , Figure 10As shown, preferably, to ensure that the telescopic rod 191 rotates at an angle of 180° each time, a guide cylinder 161 is vertically arranged on the strip platform 16. The guide cylinder 161 is coaxially arranged outside the telescopic rod 191, and an arc-shaped groove 162 is formed in the cross-sectional direction of the guide cylinder 161. A guide pin 195 is vertically arranged on the outer wall of the fixed rod of the telescopic rod 191. The guide pin 195 is slidably engaged with the arc-shaped groove 162. The arc length of the arc-shaped groove 162 is equal to 180°, which is equal to half of the cross-section of the guide cylinder 161 and the diameter of the guide pin 195.

[0049] Preferably, the rectangular frame structure with the cross-section of the clamping seat 193 allows the clamping seat 193 to automatically push the next clamping block 2 backward a certain distance when clamping the locking block 2 vertically downward, without the need for additional intercepting parts. This not only avoids accidentally picking up the next clamping block 2, but also improves the stability of the locking block 2 entering the clamping seat 193 during the clamping process.

[0050] Specific operating procedures:

[0051] Place the nut 3 into the two corresponding material tubes of the material tube rack 12, place the clamp 1 into the second conveyor belt 18, and transport the clamp 1 along the length direction of the second conveyor belt 18. Place the two sides of the locking block 2 with flat surfaces into the conveying area along the conveying direction parallel to the first conveyor belt 17. Start the first cylinder 142, so that the push plate 141 pushes the nut 3 along the U-shaped seat 13 into the corresponding hexagonal blind hole 111 of the base 11.

[0052] When the locking block 2 is conveyed to the end of the conveying direction of the first conveyor belt 17, the telescopic rod 191 is shortened vertically downward so that the cantilever 192 moves vertically downward. The cantilever 192 drives the clamping seat 193 downward. The limiting pin 196 is located in the step hole 194 and the limiting plate clamps the planes on both sides of the locking block 2. Then the telescopic rod 191 moves vertically upward so that the clamping seat 193 clamps the locking block 2 vertically upward. At this time, the clamping body 1 is conveyed to the assembly frame 15 along the second conveyor belt 18.

[0053] Activating the second cylinder 26 causes it to push the horizontal plate 23 towards the base 11, thereby pushing the T-shaped plate 24 along the direction of the side panel to move the clamp 1, which is inside the assembly frame 15, towards the inner support arm of the side panel, until both sides of the clamp 1 are limited by the inner support arm of the side panel and the horizontal part of the T-shaped plate 24, respectively. Simultaneously, the horizontal plate 23 pushes the rack 22 towards the material-feeding direction of the first conveyor belt 17, thereby causing the gear 21 to rotate 180 degrees towards the direction of the second conveyor belt 18. After the extension rod 193 stops, it drives the clamping seat 193 holding the locking block 2 to move directly above the clamping body 1 which is limited. Then the extension rod 193 moves vertically downward so that the screw at the lower end of the locking block 2 is inserted vertically downward into the clearance hole 151 along the two round holes on the clamping body 1. Then the rotary motor is started so that the rotary motor drives the clamping seat 193 to rotate, thereby rotating the locking block 2 so that the screw at the lower end of the locking block 2 is threadedly connected to the nut 3 to realize the pre-assembly of the suspension clamp.

[0054] Then the telescopic rod 191 extends vertically upward, thereby disengaging the clamping seat 193 from the locking block 2. The second cylinder 26 is activated again, causing the second cylinder 26 to move the horizontal plate 23 away from the base 11. The horizontal plate 23 drives the rack 22 to move in the opposite direction, thereby rotating the gear 21 180°. At the same time, the T-shaped plate 24 moves to the outer support arm of the enclosure and remains in the receiving groove to prevent the next clamping body 1 from entering the assembly frame 15.

[0055] The above description is merely a preferred embodiment of the present invention and is not intended to be the only or limiting of the invention. Those skilled in the art should understand that various changes or equivalent substitutions made to the present invention without departing from its scope are all within the protection scope of the present invention.
