Description

Technical Field

[0001] The utility model relates to the technical field of insulators, in particular to a porcelain insulator anti-falling device. Background Art

[0002] Insulators are a special type of insulating control that can play an important role in overhead transmission lines. In the early years, insulators were mostly used on utility poles, and gradually developed into high-type high-voltage power lines. Many disc-shaped insulators are hung on one end of the tower to increase the creepage distance. They are usually made of glass or ceramics and are called insulators. Among them, porcelain insulators have good chemical and thermal stability, strong anti-aging ability, good electrical and mechanical properties, and flexible assembly.

[0003] It should be noted that before and after the installation of the insulator, it is necessary to avoid impact on the insulator as much as possible to prevent cracks from occurring inside the insulator, which will affect the utilization rate of the insulator. After the insulator is transported to the construction site, since the metal seats at the upper and lower ends of the insulator are irregular columns, the insulator cannot be placed vertically on the ground and can only be placed flat on the ground. One side of its shed is in contact with the ground. If it is hit without a protective device, the insulator is very likely to roll outwards, and its outer shell is easily damaged during collision or rolling.

[0004] Therefore, how to design a porcelain insulator anti-fall device that can solve the above-mentioned technical problems is a technical problem that needs to be solved. Utility Model Content

[0005] In order to solve the above problems, the purpose of the utility model is to provide a porcelain insulator anti-fall device, which can prevent the insulator from tilting and falling and rolling after being hit, and avoid damage to the shell.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: it includes a hemispherical anti-fall base and an anti-fall cover body detachably arranged on the upper end surface of the anti-fall base; a counterweight block is embedded in the bottom of the anti-fall base, a through hole is opened at the center position of the upper end surface of the anti-fall base for convenient passage of the metal seat, three slide grooves are opened at equal distances along the circumference of the through hole on the upper end surface of the anti-fall base, an installation groove is opened just below the slide groove in the anti-fall base, a half-tooth turbine is arranged at the bottom of the installation groove through a rotating shaft, a connecting block is fixedly connected to the upper end surface of the half-tooth turbine, and a metal plate is opened at the corresponding position of the through hole on the connecting block. The seat mounting groove has three guide grooves obliquely arranged at the upper end surface of the connecting block corresponding to the three slide groove positions; limit push rods are slidably arranged in the slide grooves, and guide sliders are fixedly arranged at the bottom of the limit push rods, and the guide sliders extend through the bottom of the slide groove into the mounting groove, and the ends are clamped in the guide grooves; a transmission worm is also arranged on the side of the mounting groove corresponding to the half-tooth turbine gear, and the transmission worm is meshed with the half-tooth turbine, one end of the transmission worm is rotatably connected to the side wall of the mounting groove, and the other end extends through the side wall of the anti-fall base to the outside of the anti-fall base and the end is fixedly connected to a rotating block.

[0007] Furthermore, a connection ring groove matching the bottom of the anti-fall cover body is formed on the upper end surface of the anti-fall base along its circumference.

[0008] Furthermore, a through groove for the guide slider to slide is provided at the bottom of the slide groove.

[0009] Furthermore, an arc-shaped push block matched with the outer peripheral wall of the metal seat is provided at an end of the limit push rod close to one end of the through hole.

[0010] Furthermore, guide slots are provided on the left and right side walls inside the slot along the length direction thereof, and guide blocks are provided at positions corresponding to the guide slots on both sides of the limiting push rod, and the guide blocks are clamped in the guide slots.

[0011] Furthermore, the inner wall of the anti-fall cover is covered with a silicone cushion.

[0012] Furthermore, the anti-fall cover is provided with a taking groove for facilitating the movement of the anti-fall cover.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model is provided with a hemispherical anti-fall base with a counterweight embedded inside. Under normal circumstances, the anti-fall base is placed flat on the ground. When the anti-fall base is hit and tilted, a torque is generated between the counterweight and the landing point. Under the action of the torque, the anti-fall base is reset to prevent the insulator on the anti-fall base from tipping over and colliding with the ground.

[0015] 2. The utility model sets a limit push rod on the upper end surface of the anti-fall base for sliding movement. The guide slider is driven to move along the direction of the slide groove and the guide slide groove at the same time through the rotation of the transmission turbine, so that the limit push rod moves toward the center position of the through hole, and the arc-shaped push block at its end clamps the lower metal seat of the insulator to fix the insulator metal seat.

[0016] 3. The utility model is provided with an anti-fall cover, which, on the one hand, prevents workers from accidentally touching the insulator, and on the other hand, reduces the impact force that the insulator may receive to avoid damage. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments:

[0027] See also Figure 1-6 As shown, the scheme includes a hemispherical anti-fall base 1 and an anti-fall cover 2 detachably arranged on the upper end surface of the anti-fall base 1; the outer bottom surface of the anti-fall base 1 is arranged to be large and smooth, so that there is a larger supporting surface between the bottom surface of the anti-fall base 1 and the ground.

[0028] A counterweight 11 is embedded in the bottom of the anti-drop base 1, and the mass of the counterweight 11 is much greater than the mass of the insulator metal seat. A through hole 12 is provided at the center of the upper end surface of the anti-drop base 1 for the metal seat to pass through, and three slide grooves 13 are provided at equal intervals along the circumference of the through hole 12 on the upper end surface of the anti-drop base 1. A mounting groove 14 is provided just below the slide groove 13 in the anti-drop base 1, and a half-tooth turbine 141 is provided at the bottom of the mounting groove 14 through rotation of a rotating shaft, and a connecting block 142 is fixedly connected to the upper end surface of the half-tooth turbine 141, and a metal seat mounting groove 142114 is provided on the connecting block 142 at the position corresponding to the through hole 12, and three guide grooves 1422 are also obliquely provided at the positions corresponding to the three slide grooves 13 on the upper end surface of the connecting block 142; A limiting push rod 131 is slidably provided in the slide groove 13, and a guide slider 1311 is fixedly provided at the bottom of the limiting push rod 131. The guide slider 1311 passes through the bottom of the slide groove 13 and extends into the installation groove 14, and the end portion is clamped in the guide groove 1422; a transmission worm 15 is also provided on the side of the gear corresponding to the half-tooth turbine 141 in the installation groove 14, and the transmission worm 15 is meshedly connected with the half-tooth turbine 141, one end of the transmission worm 15 is rotatably connected to the side wall of the installation groove 14, and the other end passes through the side wall of the anti-fall base 1 and extends to the outside of the anti-fall base 1, and a rotating block 151 is fixedly connected to the end portion.

[0029] The upper end surface of the anti-fall base 1 is provided with a connecting ring groove 16 along its circumference that matches the bottom of the anti-fall cover body 2. The anti-fall cover body 2 and the connecting ring groove 16 are connected by an interference fit. At the same time, in order to facilitate workers to disassemble the anti-fall cover body 2, this embodiment provides a taking groove 22 on the anti-fall cover body 2 for conveniently moving the anti-fall cover body 2.

[0030] Furthermore, a through groove 132 for the guide slider 1311 to slide is formed at the bottom of the slide groove 13.

[0031] Furthermore, an arc-shaped push block 1312 adapted to the outer peripheral wall of the metal seat is provided at one end of the limiting push rod 131 close to the through hole 12 .

[0032] A guide slot 133 is provided on the left and right side walls inside the slot 13 along its length direction. Guide blocks 1313 are provided at the positions corresponding to the guide slot 133 on both sides of the limiting push rod 131 . The guide blocks 1313 are clamped in the guide slot 133 .

[0033] The inner wall of the anti-fall cover 2 is covered with a silicone cushion 21 to avoid the impact force generated when the anti-fall cover 2 collides as much as possible.

[0034] The working principle is roughly as follows:

[0035] The worker places the lower metal seat of the insulator through the through hole 12 into the metal seat installation groove 142114. Figure 5 As shown, at this time, the transmission worm 15 is rotated by the rotating block 151, so that the transmission worm 15 drives the half-tooth turbine 141 to rotate; when the half-tooth turbine 141 rotates, the connecting block 142 rotates to drive the guide slider 1311 to move forward and backward along the slide groove 13 and the guide groove 1422, and the arc-shaped push block 1312 at the end of the limit push rod 131 moves toward the center direction of the through hole 12 (as shown in FIG. Figure 6 As shown), the arc-shaped push block 1312 is closely attached to and fixes the metal seat under the insulator;

[0036] Finally, the anti-fall cover 2 is placed on top of the anti-fall base 1 through the connecting ring groove 16. Under normal circumstances, the anti-fall base 1 is placed flat on the ground. When the anti-fall base 1 is hit, the anti-fall base 1 tilts, and a torque is generated between the bottom counterweight block 11 inside the anti-fall base 1 and the landing point. Under the action of the torque, the anti-fall base 1 is reset to prevent the anti-fall base 1 from falling down and the insulator inside the anti-fall cover 2 from touching the ground and colliding.

Any equivalent structural transformation made using the contents of the utility model specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the utility model.
