Description

Technical Field

[0001] The utility model relates to the technical field of clamping, in particular to an auxiliary clamping device for an insulating basin. Background Art

[0002] The pot insulator is an insulating device used in power transmission lines. Its main function is to isolate the conductor from metal structures such as brackets and towers, thereby playing an insulating role and preventing power accidents. According to different uses and structural forms, pot insulators can be divided into several categories, such as power pot insulators, railway pot insulators and communication pot insulators. Generally speaking, there are three types: the first is the indoor type, which weighs about a few kilograms to more than ten kilograms; the second is the outdoor type, which weighs about tens to hundreds of kilograms; the third is the high-voltage type, which may weigh hundreds of kilograms or even more.

[0003] In the process of implementing this solution, the inventors found that the following problems in the prior art have not been well solved: when assembling insulating basins in the traditional way, lighter insulators can be manually lifted for assembly, but some heavier insulating basins require manual lifting for assembly, which is physically demanding and dangerous, and some very heavy ones cannot be assembled manually. Utility Model Content

[0004] The main purpose of the utility model is to provide an auxiliary clamping device for an insulating basin, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] An auxiliary clamping device for an insulating basin comprises a base, a square frame is provided on the top of the base, the front and rear ends of both sides of the square frame are threadedly connected with adjusting screws, four arc-shaped clamping plates are provided inside the square frame, movable seats are fixed at one end of the arc-shaped clamping plates close to the adjusting screws, swivel seats are provided inside the movable seats, positioning holes are drilled through both ends of the square frame, adjusting grooves are drilled at both ends of the top of the base, sliders are slidably connected inside the adjusting grooves, positioning columns are fixed on the tops of the sliders, and adjusting rods are inserted through the positions of the base located in the adjusting grooves.

[0007] Preferably, the positioning posts are respectively connected to positioning holes that match the positions, and the outer diameters of the positioning posts are respectively matched to the inner diameters of the positioning holes.

[0008] Preferably, the movable seats are rotatably connected to the rotating seats respectively, and the adjusting screws are rotatably connected to the rotating seats with matching positions respectively.

[0009] Preferably, side seats are fixed to the outer side walls at both ends of the square frame, and spring rods are fixed to the bottoms of the side seats.

[0010] Preferably, one end of the adjusting rod is respectively inserted into the inside of the adjusting groove, and the one end is rotatably connected to the inner side wall of the adjusting groove.

[0011] Preferably, the outer wall of the adjusting rod at one end inside the adjusting groove is provided with threaded teeth, and the adjusting rod is respectively connected with the slider through the thread, the slider is respectively provided with a threaded groove at the position of the adjusting rod, and the adjusting rod is respectively threadedly connected with the threaded groove on the slider through the threaded teeth.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The square frame is sleeved on the outside of the insulating basin. The rotation of the adjusting screw can drive the arc clamping plate close to the outer wall of the basin. The adjusting screw can be pressed against the outer wall of the basin through the movement of the movable seat and the continuous rotation of the adjusting screw, and a tight clamping effect is achieved. At this time, the square frame and the basin become one, and then the square frame can be hoisted by the hoisting device during assembly.

[0014] The hoisting device adjusts the square frame to the top of the base and then lowers it. When lowering, the positioning holes on the square frame are interlaced with the positioning columns through manual fine-tuning of the square frame, so that the lowering of the square frame has a vertical effect. The next basin is also stacked in this way and then installed after stacking. When the upper square frame is lowered and stacked on the lower square frame, the spring rods on both sides of the upper side will press on the top of the lower side seat, so that the descent has a buffering effect, avoiding unnecessary hidden dangers caused by excessive descent speed;

[0015] The rotation of the adjusting screw itself can drive the arc-shaped clamp to clamp the outer wall of the insulating basins of different sizes. After multiple basins are assembled, the adjusting screw can be disengaged by flipping, so that the square frame can be easily taken out from the outside of the basin. Then the rotation of the adjusting rod can drive the slider to slide in the adjusting groove, so that the positioning columns are away from each other, avoiding unnecessary damage caused by the lifting device touching the positioning columns when moving the assembled insulating basin away.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-4 As shown, an auxiliary clamping device for an insulating basin comprises a base 1, a square frame 2 is arranged above the base 1, the front and rear ends of both sides of the square frame 2 are threadedly connected with adjusting screws 21, four arc-shaped clamping plates 22 are arranged inside the square frame 2, a movable seat 23 is fixed to one end of the arc-shaped clamping plate 22 close to the adjusting screw 21, a swivel seat 24 is arranged inside the movable seat 23, positioning holes 27 are drilled through both ends of the square frame 2, adjusting grooves 11 are drilled at both ends of the top of the base 1, a slider 13 is slidably connected inside the adjusting groove 11, a positioning column 14 is fixed on the top of the slider 13, and an adjusting rod 12 is inserted through the position of the base 1 located in the adjusting groove 11.

[0023] Specifically, the positioning posts 14 are respectively connected with the positioning holes 27 of matching positions, and the outer diameters of the positioning posts 14 are respectively matched with the inner diameters of the positioning holes 27, so that the descent of the square frame 2 is vertical, avoiding shaking due to size difference.

[0024] Specifically, the movable seats 23 are rotatably connected to the rotating seats 24 respectively, and the adjusting screws 21 are rotatably connected to the rotating seats 24 with matching positions respectively, so that the arc clamping plate 22 can clamp the outer wall of the basin by moving and rotating horizontally.

[0025] Specifically, side seats 25 are fixed to the outer side walls at both ends of the square frame 2, and spring rods 26 are fixed to the bottoms of the side seats 25, so that a buffering effect is achieved when the upper square frame 2 descends.

[0026] Specifically, one end of the adjusting rod 12 is respectively inserted into the inside of the adjusting groove 11, and the one end is rotatably connected to the inner wall of the adjusting groove 11, and the outer wall of the adjusting rod 12 at one end of the adjusting groove 11 is provided with threaded teeth, and the adjusting rod 12 is respectively connected with the slider 13, and the slider 13 is located at the position of the adjusting rod 12. The position of the slider 13 is drilled with a threaded groove, and the adjusting rod 12 is threadedly connected with the threaded groove on the slider 13 through the threaded teeth, so that the rotation of the adjusting rod 12 can drive the positioning column 14 to move closer to or away from each other, which is convenient for passing through the positioning hole 27 by adjusting the position during assembly, and moving away from the insulating basin by adjusting the position after assembly.

[0027] Working principle:

[0028] The square frame 2 is sleeved on the outside of the insulating basin. The rotation of the adjusting screw 21 can drive the arc clamping plate 22 to approach the outer wall of the basin. The adjusting screw 21 can be pressed against the outer wall of the basin through the movement of the movable seat 23 and the continued rotation of the adjusting screw 21, and a tight clamping effect is achieved. At this time, the square frame 2 and the basin become one, and then the square frame 2 can be hoisted by the hoisting device during assembly.

[0029] The hoisting device adjusts the square frame 2 to the top of the base 1 and then lowers it. When lowering, the positioning holes 27 on the square frame 2 are interlaced with the positioning columns 14 by manually fine-tuning the square frame 2, so that the lowering of the square frame 2 has a vertical effect. The next basin is also stacked in this way and then installed after stacking. When the upper square frame 2 is lowered and stacked on the lower square frame 2, the spring rods 26 on both sides of the upper side will press on the top of the lower side seat 25, so that the lowering has a buffering effect, avoiding unnecessary hidden dangers caused by too fast a lowering speed.

[0030] The rotation of the adjusting screw 21 can drive the arc-shaped clamping plate 22 to clamp the outer wall of the insulating basins of different sizes. After multiple basins are assembled, the adjusting screw 21 can be disengaged by flipping, so that the square frame 2 can be easily taken out from the outside of the basin. Then, the rotation of the adjusting rod 12 can drive the slider 13 to slide in the adjusting groove 11, so that the positioning columns 14 are away from each other, avoiding unnecessary damage to the positioning columns 14 when the lifting device moves the assembled insulating basin away.
