Description

Technical Field

[0001] The utility model belongs to the technical field related to lightning arresters, and particularly relates to a flange installation device for an end cover of a line lightning arrester. Background Art

[0002] Line type arresters are supplied in large quantities all year round, and are relatively light in weight. Their surfaces have good hydrophobic migration properties. Line type arresters are mainly composed of composite silicone rubber, end cover flanges, and core groups. The core group includes resistors, aluminum pads, epoxy cloth tubes, electrodes, and springs. End covers are added at both ends of line type arresters with voltage levels of 110kV and above to ensure that the product is well sealed and does not invade moisture. After the core group is assembled, the end cover flange needs to be screwed to the epoxy cloth tube, but there are still the following disadvantages in the installation process of the arrester end cover flange:

[0003] In the past, during the installation of the arrester end cover flange, the end cover flange was mostly installed on the epoxy cloth tube manually, which easily caused problems such as uneven force, insufficient centering, time-consuming and labor-intensive, low efficiency, and low pass rate.

[0004] Secondly, the relative size of the lightning arrester is still slightly large. If the lightning arrester is not assisted and fixed, it is difficult to perfectly screw on the end cover flange. Even if one end of the lightning arrester is clamped, screwing the other end on the end cover flange may cause inaccurate positioning and problems with screwing in. Utility Model Content

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a line arrester end cover flange installation device, comprising a chain conveyor, an installation assembly and a positioning assembly, wherein the chain conveyor comprises two frames, legs are fixed at both ends of the bottom of the two frames, and a reinforcing base plate is fixed outside the legs, two symmetrically distributed through slots are opened through the middle of the frame, and a pressure switch is fixed at the upper end of the frame between the two through slots;

[0009] A group of positioning components is arranged in the middle area of ​​each frame, and the positioning components include a lifting cylinder fixed on the reinforcing base plate and an arc-shaped clamping claw rotatably connected in the through groove, and the two arc-shaped clamping claws in the same frame are symmetrically distributed.

[0010] Furthermore, rollers are connected for common rotation between the opposite and adjacent ends of the two frames, two sprockets are fixed to the outer periphery of each roller, and a chain is transmitted between the two sprockets on the same straight line of the two rollers.

[0011] Furthermore, a plurality of groups of equidistantly distributed position limiting members are fixed to the side surfaces of each chain, and the position limiting members on both sides of each chain are symmetrically distributed about the longitudinal center line of the chain.

[0012] Furthermore, there is a gap between each chain and the frame adjacent thereto for the arrester insulator to pass through.

[0013] Furthermore, a lifting plate is fixed to the telescopic end of the lifting cylinder, two symmetrically distributed hinges are fixed to the top surface of the lifting plate, and hinges 2 are fixed to the outer arc surface of each arc-shaped clamp, and hinges 1 and hinges 2 above the hinges are hingedly connected with a connecting rod.

[0014] Furthermore, the length of the through slot is greater than the rotation radius of the arc-shaped clamping jaw, the lower portion of the arc-shaped clamping jaw rotates in the through slot, and the upper portion of the arc-shaped clamping jaw extends out of the through slot.

[0015] Furthermore, the axes of the displacement cylinder and the motor are on the same straight line, and are also on the same straight line with the center of the frame when viewed from a top view.

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0029] See also Figure 1-6As shown, the utility model is a line arrester end cover flange installation device, including a chain conveyor 1, a mounting assembly 2 and a positioning assembly 3, the chain conveyor 1 includes two frames 101, legs 103 are fixed at both ends of the bottom of the two frames 101, and a reinforcing base plate 104 is fixed outside the legs 103, two symmetrically distributed through slots 1011 are opened through the middle of the frame 101, and a pressure switch 107 is fixed on the upper end of the frame 101 between the two through slots 1011;

[0030] The chain conveyor 1 is a conventional structure on the market, and is not specifically limited. It is additionally installed with a reinforcing base plate 104 to enhance the structural strength, and is provided with a through slot 1011. An arc-shaped clamping claw 303 is provided in the through slot 1011 for auxiliary clamping. A pressure switch 107 is provided to control the start and stop of the chain conveyor 1 and the start and stop of the lifting cylinder 301.

[0031] Two groups of mounting components 2 are symmetrically distributed outside the chain conveyor 1. The mounting components 2 include a column 201 and a displacement cylinder 202 fixed to the side of the column 201. An L-shaped mounting frame 205 is fixed to the telescopic end of the displacement cylinder 202. A motor 203 is fixed to the mounting frame 205, and a gripper manipulator 204 is fixed to the output shaft of the motor 203.

[0032] Two sets of installation components 2 are used in cooperation for the installation of the arrester and the end cover flange. The clamping manipulator 204 in one installation component 2 is used to clamp one end of the arrester, and the clamping manipulator 204 in the other installation component 2 is used to clamp the end cover flange. The motor 203 and the displacement cylinder 202 of the installation component 2 work at the same time. The displacement cylinder 202 drives the clamping manipulator 204 to approach the end of the epoxy cloth tube of the arrester. At the same time, the motor 203 drives the clamping manipulator 204 to rotate, so that the end cover flange is rotated to the outside of the epoxy cloth tube for screw-on installation, and the assembly is completed.

[0033] A set of positioning components 3 is disposed in the middle area of ​​each frame 101. The positioning components 3 include a lifting cylinder 301 fixed on the reinforcing base plate 104 and an arc-shaped clamping claw 303 rotatably connected to the through slot 1011. The two arc-shaped clamping claws 303 in the same frame 101 are symmetrically distributed.

[0034] By utilizing the operation of the lifting cylinder 301, it is possible to control whether the arc-shaped clamping claw 303 extends out of the through slot 1011. When the arc-shaped clamping claw 303 extends out of the through slot 1011, the epoxy cloth tube of the lightning arrester can be clamped and fixed.

[0035] The ends of the two frames 101 facing each other and close to each other are connected to a roller 102 for common rotation. Two sprockets 1021 are fixed to the outer periphery of each roller 102. A chain 105 is commonly driven between the two sprockets 1021 on the same straight line of the two rollers 102.

[0036] For the convenience of intuitive representation, the specific chain 105 structure is not drawn in the figure. A roller 102 is installed between the frame 101, and a sprocket 1021 is installed on the roller 102. The sprocket 1021 drives the chain 105 to rotate. This belongs to the conventional chain conveyor 1 structure, and the drive diagram of the chain conveyor 1 is not shown.

[0037] A plurality of equally spaced groups of limit members 106 are fixed to the side of each chain 105, and the limit members 106 on both sides of each chain 105 are symmetrically distributed about the longitudinal center line of the chain 105; the limit members 106 are installed on the chain links of the chain 105, and a group of limit members 106 is two symmetrical ones, and the upper end faces of the limit members 106 are curved surfaces, which are used to assist in fitting to the outer surface of the epoxy cloth tube of the arrester, and to assist in positioning and conveying, so that the arrester will not directly contact the chain 105 and the frame 101.

[0038] There is a gap between each chain 105 and the rack 101 adjacent thereto for the arrester insulator to pass through; and the gap between two adjacent insulators on the arrester is greater than the width of the rack 101, which can be achieved as follows Figure 1 Delivery shown.

[0039] The telescopic end of the lifting cylinder 301 is fixed with a lifting plate 302, and the top surface of the lifting plate 302 is fixed with two symmetrically distributed hinges 1 3021, and the outer arc surface of each arc-shaped clamping claw 303 is fixed with a hinge 2 3031, and a connecting rod 304 is hingedly connected between the hinge 1 3021 and the hinge 2 3031 above it;

[0040] The lifting cylinder 301 works to drive the lifting plate 302 to move up and down, thereby realizing the movement of the connecting rod 304 under the action of the hinge 1 3021 and the hinge 2 3031, thereby driving the rotation movement of the arc-shaped clamping claw 303 to realize the clamping of the lightning arrester.

[0041] The length of the through slot 1011 is greater than the rotation radius of the arc-shaped clamping jaw 303 . The lower portion of the arc-shaped clamping jaw 303 rotates in the through slot 1011 , and the upper portion of the arc-shaped clamping jaw 303 extends out of the through slot 1011 . Thus, the rotation of the arc-shaped clamping jaw 303 will not be affected by the through slot 1011 .

[0042] The axes of the displacement cylinder 202 and the motor 203 are on the same straight line, and are also on the same straight line with the center of the frame 101 when viewed from a top view. The axes of the displacement cylinder 202 and the motor 203 are on the same straight line with the axis of the arrester.

[0043] The specific working principle of the utility model is as follows: first, the arrester is placed in the limiter 106 on the chain 105 in the chain conveyor 1, and the same arrester is temporarily supported and conveyed by the limiter components on the two chains 105, so that the arrester will not directly contact the chain 105 and the frame 101, and the roller 102 is connected to the external drive, and after rotation, the sprocket 1021 and the chain 105 drive the arrester for transportation. When the arrester runs to the central area of ​​the chain conveyor 1, the contact pressure switch 107 is contacted, and the chain conveyor 1 stops running. At this time, the lifting cylinder 301 works to drive the lifting plate 302 to rise, so that the movement of the connecting rod 304 is realized under the action of the hinge 1 3021 and the hinge 2 3031. Under the action of the connecting rod 304, the two arc-shaped clamping claws 303 extend out of the through slot 1011 to clamp the epoxy cloth tube of the arrester to assist in positioning;

[0044] At the same time, the gripper manipulator 204 in one installation component 2 grips one end of the arrester, and the gripper manipulator 204 in the other installation component 2 grips the end cover flange. The motor 203 and the displacement cylinder 202 of the installation component 2 work simultaneously. The displacement cylinder 202 drives the gripper manipulator 204 to approach the end of the epoxy cloth tube of the arrester. At the same time, the motor 203 drives the gripper manipulator 204 to rotate, so that the end cover flange is rotated to the outside of the epoxy cloth tube for screw-on installation, completing the assembly, thereby improving the coaxial centerliness of the end cover flange assembly and improving the production efficiency of line-type arresters.

[0045] The above are only preferred embodiments of the present invention and do not limit the present invention. Any modification to the technical solutions recorded in the aforementioned embodiments and any equivalent replacement of some of the technical features therein, any modification, equivalent replacement, and improvement made are all within the protection scope of the present invention.
