Description

Technical Field

[0001] The present invention relates to the technical field of insulator string production, and particularly to a power insulator manufacturing and assembling machine and an assembling process. Background Art

[0002] The assembly of insulator strings is an important part of the installation work of power lines in the power system, mainly used to support conductors and ensure the safe operation of the power system. An insulator string is composed of multiple insulators connected in series, used to isolate the current from the conductor to the metal tower or support structure, and at the same time bear external forces such as the weight of the conductor and wind load.

[0003] Nowadays, due to the special shape of insulator strings and their easy breakage, they are usually assembled one by one on the splicing table by manual handling during assembly. This assembly method not only consumes a large amount of manpower, but also easily results in uneven quality during the assembly process. Therefore, in order to prevent the knocking of insulators caused by human fatigue, we propose a new type of assembly machine to improve the assembly efficiency and reduce the labor intensity of assembly workers. Summary of the Invention

A longitudinal through hole is opened in the middle of the fixed base near the feeding end, and rectangular gaps and installation slots communicating with the longitudinal through hole are respectively opened in the middle of both sides of the longitudinal through hole. A ground rail for supporting the assembled insulator string is clamped in the installation slot. A pressing mechanism is arranged on the upper surface of the fixed base above the longitudinal through hole; on the inner walls of the two opposite sides of the rectangular gap, groove-shaped slide rails with opposite openings and parallel to each other are respectively fixed, and the same sliding bottom plate is slidably connected between the two groove-shaped slide rails. A clamping mechanism is arranged on the upper surface of the sliding bottom plate; a traction mechanism is arranged at one end of the fixed base far from the installation slot.

[0006] Furthermore, a forward sliding groove is opened on the upper surface of the ground rail, and the radian of the forward sliding groove is adapted to the outer diameter of the insulator string. With the setting of the traction mechanism, the assembled insulator string can be dragged along the extension direction of the ground rail, and then a position is vacated above the longitudinal through hole for the assembly of the next insulator disc.

[0007] Further settings are as follows. The traction mechanism includes a roller frame that is fixed in the middle of the end of the fixed base and extends vertically upward. A fixed pulley 1 is provided at the top of the roller frame. A rope winding mechanism is provided below the roller frame near the end of the fixed base. The rope winding mechanism includes a reel roller and a traction rope fixed on the reel. A ball head clamping part is fixed at one end of the traction rope far from the reel roller. The end of the ball head clamping part has the same shape as the cap socket of the insulator disc.

[0008] Further settings are as follows. Support columns are fixed at both ends of the upper surface of the fixed base near the two sides of the ground rail. Two parallel and horizontal fixed slide bars 2 are respectively fixed at the bottom of the opposite sides of the four support columns. The two fixed slide bars 2 extend to the outer circumference of the insulator disc near the lower left at the docking and pressing station.

[0009] Further settings are as follows. U-shaped through grooves extending towards the middle are opened at the tops of the four support columns. A resisting rod extending towards the middle is slidably connected in each U-shaped through groove. Sliding bearings are slidably sleeved at both ends of the resisting rod, and the outer walls of the sliding bearings are clamped and fixed at the bottom of the corresponding U-shaped through groove. Spring caps are fixed at the ends of the resisting rods far from the middle. Compression springs are provided on the sides of the spring caps close to the corresponding support columns. The compression springs are sleeved on the outer walls of the corresponding resisting rods. Two parallel and horizontal buffer slide bars 1 are fixed at the opposite ends of the four resisting rods. The ends of the buffer slide bars 1 and the fixed slide bars 2 close to the clamping mechanism are both provided with a conical structure. The buffer slide bar 1 is located above the center line of the insulator string. The buffer slide bar 1 is attached to the outer circumference of the insulator string.

[0010] Further settings are as follows. The pressing mechanism includes a support rod fixed on the upper surface of the fixed base near the rear end of the longitudinal through hole. A cantilever plate beam extending horizontally towards the middle is fixed at the top of the support rod. An electric telescopic rod 1 is fixed at the top of the cantilever plate beam. A connecting frame is fixed at the top of the extending rod of the electric telescopic rod 1. A strip-shaped pressing block and a fastening pin shooting gun are respectively fixed at both ends of the connecting frame. The shooting hole of the fastening pin shooting gun is located above the cap socket in the docking area. Vertical and parallel pressing rods are respectively fixed at the lower surface of the strip-shaped pressing block near both ends.

Two vertical and parallel U-shaped groove rails are fixed at the top of the cantilever plate beam. The corresponding convex sliders are slidably connected in the corresponding U-shaped groove rails. When the ball head and the cap socket need to be docked, only need to control the contraction of the extending rod of the electric telescopic rod 1.

[0011] Further setting is that a strip-shaped plate is fixed in the middle of one end of the sliding bottom plate far away from the ground rail, and a vertical movable shaft is fixed at the end of the strip-shaped plate. A hinge joint is rotatably sleeved on the circumferential outer wall of the movable shaft, and a return spring is fixed on the surface of the hinge joint. One end of the return spring far away from the hinge joint is fixed with a propulsion connecting rod; on the inner walls of the two opposite sides of the rectangular notch far away from the ground rail, an L-shaped motor bracket is fixed, and the same reduction motor is fixed between the bottom ends of the two L-shaped motor brackets. The top end of the output shaft of the reduction motor is fixed with a disc, and a rotating shaft is inserted near the edge of the upper surface of the disc. The top end of the rotating shaft is fixed at one end of the lower surface of the propulsion connecting rod far away from the return spring; a plurality of screw holes are respectively formed at both ends of the bottom of the two channel-shaped slide rails, and a positioning bolt is fixed in each of the screw holes near both ends; just by controlling the uniform rotation of the reduction motor, the sliding bottom plate can be made to have a process of stopping moving when sliding to both ends of the channel-shaped slide rail. During this pause operation process, the operations of loading and clamping or pressing and docking can be carried out.

[0012] Further setting is that a guiding insertion rod passing through the return spring is fixed at one end of the hinge joint close to the propulsion connecting rod, and a first guiding hole forming a sliding fit with the guiding insertion rod is formed at the end of the propulsion connecting rod.

[0013] Further settings are as follows. The clamping mechanism includes two abutting springs fixed above the sliding bottom plate, and the same trapezoidal support block is fixed at the top ends of the two abutting springs. Guide rods are fixed at the four corners of the lower surface of the trapezoidal support block, and through holes adapted to the diameter of the guide rods are formed on the upper surface of the sliding bottom plate. A bottom support groove is reserved on the upper surface of the trapezoidal support block near the ground rail, and symmetrically arranged hinge ear plates are fixed on the two inclined surfaces of the trapezoidal support block. Symmetrically arranged S-shaped clamping rods are rotatably connected to the two hinge ear plates respectively. Rotating shafts are reserved near the hinge ear plates of the two S-shaped clamping rods, and torsion springs are sleeved on the rotating shafts. Symmetrically arranged arc-shaped clamping blocks are fixed at the top ends of the two S-shaped clamping rods respectively. The central angle of the clamping points of the two arc-shaped clamping blocks and the bottom support groove is 120 degrees. Two protruding arc plates are reserved on one side of the trapezoidal support block near the pressing rod, and support columns adapted to the corresponding pressing rods are fixed at the top ends of the two protruding arc plates respectively. When the two pressing rods are pressed down, they just fall on the top ends of the corresponding support columns, and then the trapezoidal support block clamping the insulator disc and the two S-shaped clamping rods can be continuously pressed down until the clamping is completed. A pulley frame one and a fixed bracket are respectively fixed at the middle part of the lower surface of the sliding bottom plate. Two fixed pulleys two are arranged at the bottom end of the pulley frame one. The bottom end of the fixed bracket is fixed with an electric push rod two extending vertically downward. Two steel wire ropes are fixed at the bottom end of the extending rod of the electric push rod two. Pulley frames two are fixed at the lower surface of the sliding bottom plate near the lower sides of the two S-shaped clamping rods respectively. A fixed pulley three is rotatably connected to the pulley frame two. The steel wire ropes bypass the fixed pulley two and the fixed pulley three on the corresponding side and are fixed to the tail ends of the corresponding S-shaped clamping rods. Rectangular holes are symmetrically formed on both sides of the rectangular notch on the upper surface of the fixed base. The two S-shaped clamping rods are respectively slidably connected in the corresponding rectangular holes. By setting the electric push rod two and the S-shaped clamping rod controlled by the torsion spring, before feeding, only need to control the extending rod of the electric push rod two to extend, and the two clamped arc-shaped clamping blocks can be separated under the pulling of the two steel wire ropes. When the insulator disc is placed above the bottom support groove, then retract the extending rod of the electric push rod two to fix the insulator disc to be assembled. Then, as the disc continues to rotate, the fixed insulator disc is pushed above the longitudinal through hole.

[0014] A manufacturing and assembly process for electric insulators includes the following steps:

[0015] S1: In the feeding stage, ensure that the pressing rods in the pressing mechanism are at the top initial position. After that, when the reduction motor and the disc operate to drag the sliding bottom plate and the clamping mechanism at its top end to a position far from the ground rail, that is, at this time, the trapezoidal support block in the clamping mechanism is in a static state;

[0016] Control the extending rod of the electric push rod two to extend. Under the pulling of the two steel wire ropes, the two clamped arc-shaped clamping blocks are separated. When the insulator disc is placed above the bottom support groove, then retract the extending rod of the electric push rod two to fix the insulator disc to be assembled. Then, as the disc continues to rotate, the fixed insulator disc is pushed above the longitudinal through hole;

[0017] S2: Once the electric telescopic rod in the pressing mechanism is activated, the two pressing rods can be driven to move slowly downward until the insulator disc is pressed down as a whole until its ball head engages with the cap socket of the insulator disc on the ground rail; at this time, continue to press down and control the two arc-shaped clamping blocks to open until the edges of the bottom bracket slot lose their blocking ability; at this time, the locking pin shooting gun shoots out the fixing pin to lock the engaged part, and then control the traction mechanism to drag the assembled insulator string one body length;

[0018] S3: When enough insulator discs are assembled, just slowly lift one end.

[0019] The beneficial effects of the present invention are:

[0020] 1. By setting a clamping mechanism that cooperates with the pressing mechanism, the clamping mechanism can be slid to a place away from the docking pressing station before docking, that is, when loading, until the single insulator disk to be assembled is clamped and then sent to the docking pressing station, that is, above the longitudinal perforation for docking and assembly. This not only improves the safety performance but also expands the space for the loading position, reduces the risk of collision and knock of the insulator disk, and allows the loading stage to be replaced by a robot, reducing labor intensity and improving loading accuracy.

[0021] 2. With the provided ball head connector, when pulling the assembled insulator string, you only need to connect the ball head connector to the ball head of the first insulator disk, and then start the rope winding mechanism to slowly pull it in the horizontal direction.

[0022] 3. The buffer slide bars 1 are arranged on both sides of the insulator string near the top to further protect the insulator string and prevent it from derailing during the dragging process. In addition, during the final lifting process, only one end of the insulator string needs to be fixed on the hook to slowly break through the clamping of the buffer slide bar 1. The unlifted part is still firmly fixed on the arc groove on the upper surface of the ground rail, making unloading convenient and safe. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0036] Referring to Figures 1-11 , a manufacturing and assembling machine for electric insulators includes a fixed base 1 with an overall long strip structure. A longitudinal through hole 103 is opened in the middle of the fixed base 1 near the feeding end, and rectangular gaps 102 and mounting slots 104 communicating with the longitudinal through hole 103 are respectively opened in the middle of both sides of the longitudinal through hole 103. A ground rail 2 for supporting the assembled insulator string 25 is clamped in the mounting slot 104. The insulator string 25 is a collection of multiple assembled insulator discs. A pressing mechanism 10 is arranged on the upper surface of the fixed base 1 above the longitudinal through hole 103; on the inner walls of the two opposite sides of the rectangular gap 102, channel-shaped slide rails 15 with opposite openings and parallel to each other are respectively fixed, and the same sliding bottom plate 19 is slidably connected between the two channel-shaped slide rails 15. A clamping mechanism 22 is arranged on the upper surface of the sliding bottom plate 19; a traction mechanism 3 is arranged at one end of the fixed base 1 far from the mounting slot 104.

[0037] Specifically, by setting the clamping mechanism 22 that cooperates with the pressing mechanism 10, the clamping mechanism 22 can be slid to a place far from the docking and pressing station before docking, that is, during feeding. After a single insulator disc to be assembled is clamped, it is sent to the docking and pressing station, that is, above the longitudinal through hole 103, for docking and assembly. This not only improves the safety performance but also expands the space for the feeding position, reduces the risk of collision and knocking of the insulator discs, enables the feeding stage to be replaced by a manipulator, reduces the labor intensity, and improves the feeding accuracy.

[0038] In the present invention, a forward sliding groove is opened on the upper surface of the ground rail 2, and the radian of the forward sliding groove is adapted to the outer diameter of the insulator string 25. With the setting of the traction mechanism 3, the assembled insulator string 25 can be dragged along the extension direction of the ground rail 2, and then a position is vacated above the longitudinal through hole 103 for the assembly of the next insulator disc.

[0039] Referring to Figure 1 , Figure 4 and Figure 5, the traction mechanism 3 includes a roller frame 4 that extends vertically upward in the middle of the end of the fixed base 1, and a first fixed pulley is provided at the top of the roller frame 4. A rope winding mechanism is provided below the end of the fixed base 1 near the roller frame 4. The rope winding mechanism includes a reel roller and a traction rope 5 fixed to the reel. One end of the traction rope 5 away from the reel roller is fixed with a ball head clamping part 7; the end of the ball head clamping part 7 has the same shape as the socket of the insulator disc. By providing the ball head clamping part 7, when towing the assembled insulator string 25, only need to clamp the ball head clamping part 7 on the ball head of the first insulator disc, and then start the rope winding mechanism to slowly pull along the horizontal direction.

[0040] Refer to Figures 1-2 , on the upper surface of the fixed base 1, support columns 6 are fixed at both ends of both sides near the ground rail 2. And on the opposite side of the four support columns 6 near the bottom, two parallel and horizontal second fixed slide bars 24 are respectively fixed; and the two second fixed slide bars 24 extend to the circumferential outer wall of the insulator disc at the docking and pressing station near the lower left. By providing the two second fixed slide bars 24 extending into the docking and pressing station, not only can the assembled insulator string 25 be more stable when being towed and will not derail, but also can assist the insulator disc to be assembled to complete precise docking.

[0041] Refer to Figure 2 , U-shaped through grooves 601 extending towards the middle are opened at the tops of the four support columns 6. And a resisting rod 9 extending towards the middle is slidably connected in each U-shaped through groove 601. Both ends of the resisting rod 9 are slidably sleeved with sliding bearings, and the outer walls of the sliding bearings are clamped and fixed at the bottom of the corresponding U-shaped through groove 601. Spring caps 901 are fixed at the ends of the resisting rod 9 away from the middle. And compression springs 902 are provided on one side of the spring caps 901 close to the corresponding support column 6. The compression springs 902 are sleeved on the outer walls of the corresponding resisting rods 9; Two parallel and horizontal first buffer slide bars 8 are fixed at the opposite ends of the four resisting rods 9. And the ends of the first buffer slide bars 8 and the second fixed slide bars 24 close to the clamping mechanism 22 are both arranged in a conical structure; The first buffer slide bars 8 are located above the center line of the insulator string 25; And the first buffer slide bars 8 are attached to the circumferential outer wall of the insulator string 25; By providing the first buffer slide bars 8 on both sides of the insulator string 25 near the upper part, the insulator string 25 is further protected to prevent it from derailing during the towing process. And during the final lifting process, only need to fix one end of the insulator string 25 on the hook, and then it can slowly break through the clamping of the first buffer slide bars 8. The unfixed part still remains firmly fixed on the arc groove on the upper surface of the ground rail 2, making the unloading convenient and safe.

[0042] Refer to Figure 1 、 Figure 2 and Figure 4, the pressing mechanism 10 includes a support rod fixed to the upper surface of the fixed base 1 near the rear end of the longitudinal perforation 103.

When the ball head needs to be docked with the socket, just control the contraction of the extending rod of the electric telescopic rod 12.

[0043] Refer to Figures 1-2 , a strip-shaped plate is fixed to the middle of the end of the sliding bottom plate 19 away from the ground rail 2. And a vertical movable shaft is fixed to the end of the strip-shaped plate. The outer circumference of the movable shaft is rotatably sleeved with a hinge joint 18.

And a first guiding hole for forming a sliding fit with the guiding insertion rod is opened at the end of the propulsion connecting rod 17. By setting like this, it can be ensured that the sliding bottom plate 19 remains stationary when sliding to both ends of the channel-shaped slide rails 15.

[0045] Refer to Figure 1 、 Figures 10-11, the clamping mechanism 22 includes two abutting springs 2206 fixed above the sliding bottom plate 19, and the same trapezoidal support block is fixed at the top ends of the two abutting springs 2206. Guide rods 2212 are fixed at the four corners of the lower surface of the trapezoidal support block. Through holes adapted to the diameters of the guide rods 2212 are formed in the upper surface of the sliding bottom plate 19. A bottom support groove 2209 is reserved on one side of the upper surface of the trapezoidal support block close to the ground rail 2. Symmetrically arranged hinge ear plates 2208 are fixed on the inclined surfaces on both sides of the trapezoidal support block.

Rotating shafts are reserved at the positions of the two S-shaped clamping rods 2204 close to the hinge ear plates 2208, and torsion springs are sleeved on the rotating shafts. Arc-shaped clamping blocks 2207 are symmetrically fixed at the top ends of the two S-shaped clamping rods 2204. The central angle of the clamping points of the two arc-shaped clamping blocks 2207 and the bottom support groove 2209 is 120 degrees. Two protruding arc plates 2213 are reserved on one side of the trapezoidal support block close to the pressing rod 14, and support columns 2205 adapted to the corresponding pressing rods 14 are fixed at the top ends of the two protruding arc plates 2213.

[0046] Specifically, when the two pressing rods 14 are pressed down, they exactly fall on the top ends of the corresponding support columns 2205, and then the trapezoidal support block clamping the insulator disc together with the two S-shaped clamping rods 2204 can be continuously pressed down until the clamping is completed.

Rectangular holes 101 are symmetrically formed on both sides of the rectangular notch 102 on the upper surface of the fixed base 1. The two S-shaped clamping rods 2204 are respectively slidably connected in the corresponding rectangular holes 101. By setting the electric push rod two 2202 and the S-shaped clamping rods 2204 controlled by torsion springs, before feeding, only need to control the extending rod of the electric push rod two 2202 to extend, and the two clamped arc-shaped clamping blocks 2207 can be separated under the pulling of the two steel wire ropes 2211. When the insulator disc is placed above the bottom support groove 2209, then retract the extending rod of the electric push rod two 2202.

[0047] A manufacturing and assembly process for electric insulators includes the following steps:

[0048] S1: In the feeding stage, ensure that the pressure rod 14 in the downward pressing mechanism 10 is at the top initial position. After the operation of the deceleration motor 20 and the disc 21 drags the sliding bottom plate 19 and the clamping mechanism 22 at its top to a position away from the ground rail 2, that is, at this time, the trapezoidal support block in the clamping mechanism 22 is in a stationary state;

[0049] Control the extension rod of the electric push rod two 2202 to extend. Under the pulling of two steel wire ropes 2211, separate the two clamped arc-shaped clamping blocks 2207. When the insulator disc is placed above the bottom support groove 2209, then retract the extension rod of the electric push rod two 2202 to fix the insulator disc to be assembled. Then, as the disc 21 continues to rotate, push the fixed insulator disc above the longitudinal through hole 103;

[0050] S2: Control the electric telescopic rod one 12 in the downward pressing mechanism 10 to start. At this time, it can drive the two pressure rods 14 to slowly move down until the whole insulator disc is pressed down until its ball head is engaged with the cap socket of the insulator disc on the ground rail 2; At this time, continue to press down, and control the two arc-shaped clamping blocks 2207 to open until the edge of the bottom support groove 2209 loses the blocking ability; At this time, the fastening pin shooting gun 1101 shoots out the fixing pin to lock the engaged part. Then, control the traction mechanism 3 to drag the assembled insulator string for one body position;

[0051] S3: When the number of insulator discs assembled is enough, directly slowly lift one end.
