[0038] The specific embodiments shown below are intended to be descriptions of various configurations of the subject technology of the present invention, and are not intended to represent the only configuration in which the subject technology of the present invention can be practiced. The specific embodiments include specific details intended to provide a thorough understanding of the subject technology of the present invention. However, it will be clear and obvious to those skilled in the art that the subject technology of the present invention is not limited to the specific details shown herein, and can be practiced without these specific details.
[0039] Reference Figures 1 to 6 As shown, a shock absorbing device for electric power facilities comprises a bracket 1 and an equipment mounting frame 2 suspended on the bracket 1;
[0040] The bracket 1 includes an upper frame 11 and a lower frame 12, and a connecting column 13 is provided between the upper frame 11 and the lower frame 12. There are multiple connecting columns 13, and the multiple connecting columns 13 are evenly distributed around the upper frame 11 and the lower frame 12;
[0041] The equipment mounting frame 2 is located between the upper frame 11 and the lower frame 12, and the equipment mounting frame 2 is provided with a clearance hole for accommodating the connecting column 13, wherein the connecting column 13 does not contact the side wall of the clearance hole; the gap between the connecting column 13 and the clearance hole can be as small as possible, and the smaller the gap between the connecting column 13 and the clearance hole, the smaller the inclination amplitude of the equipment mounting frame 2, that is, when the equipment mounting frame 2 is tilted due to an accident, the smaller the gap between the connecting column 13 and the clearance hole, the earlier the connecting column 13 interferes with the side wall of the clearance hole, thereby preventing the equipment mounting frame 2 from tilting too much and causing damage to the power facilities installed on the equipment mounting frame 2.
[0042] The connecting column 13 is provided with a spring for assisting in positioning the equipment mounting frame 2;
[0043] Positioning steel cables 21 are respectively provided between the equipment mounting frame 2 and the upper frame 11 and the lower frame 12 ; the equipment mounting frame 2 is also provided with a counterweight block 22 for keeping the equipment mounting frame 2 in a horizontal state.
[0044] Reference Figures 1 to 6 As shown, in some embodiments, the positioning steel cable 21 includes a steel wire rope 211 fixed to the equipment mounting frame 2, the steel wire rope 211 is provided with a tensioning screw 212, the bracket 1 is provided with an assembly hole for passing the tensioning screw 212, and the bracket 1 is also provided with a tensioning nut 213 cooperating with the tensioning screw 212, wherein the upper frame 11 and the lower frame 12 are both provided with assembly holes.
[0045] The steel wire rope 211 has a certain flexibility. Therefore, the equipment mounting frame 2 is installed on the bracket 1 by positioning the steel wire rope 21. The equipment mounting frame 2 and the bracket 1 are not rigidly connected, thereby achieving a good shock absorption function.
[0046] Since the length of the wire rope 211 is fixed, when the equipment mounting frame 2 moves in the horizontal direction, the equipment mounting frame 2 needs to overcome gravity and move in the diagonal upward direction. However, the equipment mounting frame 2 is installed with power facilities. Therefore, the equipment mounting frame 2 will not move in the diagonal upward direction, so that the equipment mounting frame 2 is suspended on the bracket 1.
[0047] In some embodiments, the tensioning screw 212 is provided with a stop portion 2121 for preventing the tensioning screw 212 from rotating, the stop portion 2121 and the tensioning screw 212 are an integrated structure, and the upper frame 11 and the lower frame 12 are both provided with a matching hole that matches the stop portion 2121, and the matching hole is communicated with the assembly hole.
[0048] The upper frame 11 and the lower frame 12 are both provided with a cylinder 14 matched with the anti-rotation portion 2121, the inner cavity of the cylinder 14 is communicated with the matching hole, and the cylinder 14 is welded to the upper frame 11 and the lower frame 12 respectively.
[0049] The steel wire rope 211 is welded to the equipment mounting frame 2 , and the steel wire rope 211 is welded to the tensioning screw 212 .
[0050] The diameter of the circumscribed circle of the anti-rotation portion 2121 is greater than the maximum diameter of the tensioning screw.
[0051] The setting of the anti-rotation part 2121 is mainly used to prevent the wire rope 211 from rotating together when the tightening nut 213 is rotated, thereby causing damage to the wire rope 211 or uneven force. Therefore, by setting the anti-rotation part 2121, the wire rope 211 will not rotate when the tightening nut 213 is rotated.
[0052] The anti-rotation portion 2121 can slide in the cylinder 14 along the axial direction of the cylinder 14, that is, it can slide relative to the cylinder 14, so that when the tightening nut 213 is rotated, the tightening nut 213 cooperates with the tightening screw 212 to tighten the wire rope 211.
[0053] Reference Figures 1 to 6 As shown, in some embodiments, the positioning cables 21 and the connecting columns 13 are arranged alternately. The number of positioning cables 21 and connecting columns 13 is not limited. Generally, the more the number of connecting columns 13 and positioning cables 21, the better the stability of the shock absorbing device.
[0054] In some embodiments, the counterweight 22 is fixed to the lower end of the equipment mounting frame 2 via a connecting rod 221 .
[0055] Preferably, the counterweight block 22 is spherical, the connecting rod 221 and the counterweight block 22 are an integrated structure, and the connecting rod 221 is welded to the equipment mounting frame 2.
[0056] The counterweight block 22 and the connecting rod 221 can be coaxially arranged, and the axis of the connecting rod 221 passes through the center of gravity of the equipment mounting frame 2, so that the counterweight block 22 can effectively prevent the equipment mounting frame 2 from tilting.
[0057] At the same time, by providing the connecting rod 221, the connecting rod 221 plays a lever function, and the connecting rod 221 makes the counterweight block 22 away from the rotation center of the equipment mounting frame 2, so that the counterweight block 22 can provide a greater force to prevent the equipment mounting frame 2 from tilting.
[0058] Reference Figures 1 to 6 As shown, in some embodiments, the spring includes an upper spring 15 and a lower spring 16, the upper spring 15 is fixed to the upper frame, the lower spring 16 is fixed to the lower frame, and neither the upper spring 15 nor the lower spring 16 contacts the equipment mounting frame 2.
[0059] The distance between the upper spring 15 and the lower spring 16 and the equipment mounting frame 2 can be as small as possible, but the upper spring 15 and the lower spring 16 do not contact the equipment mounting frame 2. The smaller the distance between the upper spring 15 and the lower spring 16 and the equipment mounting frame 2, the easier it is for the upper spring 15 and the lower spring 16 to contact the equipment mounting frame 2.
[0060] For example, when the positioning steel cable 21 fails, the equipment mounting frame 2 moves downward under the action of gravity. When the equipment mounting frame 2 moves downward to a certain distance, the equipment mounting frame 2 contacts the lower spring 16 , and the lower spring 16 can support the equipment mounting frame 2 .
[0061] Therefore, the smaller the distance between the upper spring 15, the lower spring 16 and the equipment mounting frame 2, the better the performance.
[0062] The electric power facility 100 may be fixed to the equipment mounting frame 2 by screws.
[0063] The above introduces the subject technical solution of the utility model and the corresponding details. It can be understood that the above introduction is only some implementation plans of the subject technical solution of the utility model, and some details can be omitted during the specific implementation.
[0064] In addition, in some embodiments of the above utility model, multiple embodiments may be implemented in combination, and various combination schemes are not listed one by one due to space limitations. Those skilled in the art can freely combine and implement the above embodiments according to needs during specific implementation to obtain a better application experience.
[0065] When implementing the subject technical solution of the utility model, those skilled in the art can obtain other detailed configurations or drawings according to the subject technical solution of the utility model and the drawings. Obviously, these details still fall within the scope covered by the subject technical solution of the utility model without departing from the subject technical solution of the utility model.
