Description

Technical Field

[0001] The invention relates to the technical field of power transmission line maintenance tools, in particular to an insulator bottle support bracket. Background Art

[0002] The insulating bottle support rack is a hard insulating tool used to replace insulators during live working. It mainly supports the insulator string so that the insulator string can always remain in a straight line on the bottle support rack under the action of gravity.

[0003] Usually, the bottle support rack is formed by connecting a plurality of support rods in parallel, and the bottle support rack formed by the plurality of support rods is an arc-shaped structure. When repairing or replacing insulators, the staff first clamps the fixtures on the three-eye connecting plates at both ends of the insulator string, and then connects the connected screw rod and steel wire between the two fixtures, and then installs the bottle support rack under the insulator and uses the connecting part to connect the bottle support rack to the screw rod. In this way, the insulator string can be relaxed to the bottle support rack by shaking the screw rod, and the replacement or repair of the insulator is completed. However, due to the different voltage levels of the transmission lines, the models of insulators will vary, resulting in different sizes of insulators. Since the support rods in the conventional bottle support rack are relatively fixed, the arc formed by the plurality of support rods remains unchanged, resulting in poor applicability, and it cannot be used in the replacement or repair of insulators of different models, and is not limited to storage and carrying.

[0006] In the above-mentioned insulator bottle support bracket, since the bracket body is formed by a plurality of anti-drop rods arranged in parallel and connected in sequence through flexible connectors, when carrying or storing the insulator bottle support bracket, the plurality of anti-drop rods can be gathered together to reduce the volume of the bracket body, which is convenient for storage or carrying. When the insulator bottle support bracket needs to be used, the bracket body can be unfolded, and the two sides of the bracket body can be connected to the screw rod by connecting components, so that the bracket body can be suspended under the insulator. Since the adjacent anti-drop rods are flexibly connected, when the bracket body is suspended under the insulator, under the action of gravity, the bracket body surrounded by the plurality of anti-drop rods is an arc structure, and the curvature of the arc structure is adjustable.

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0026] See also Figure 1 and Figure 2 An embodiment of the present application provides an insulator bottle support bracket 10, comprising: a bracket body 110. The bracket body 110 comprises an anti-drop rod 111 and a flexible connector 112. A plurality of anti-drop rods 111 are provided, and the plurality of anti-drop rods 111 are arranged side by side. The flexible connector 112 sequentially connects the plurality of anti-drop rods 111, and a plurality of the flexible connectors 112 are provided. The plurality of flexible connectors 112 are arranged along the axial direction of the anti-drop rod 111.

[0027] In the above-mentioned insulator bottle support bracket 10, since the bracket body 110 is composed of a plurality of anti-drop rods 111 arranged in parallel and connected in sequence through flexible connectors 112, when carrying or storing the insulator bottle support bracket 10, the plurality of anti-drop rods 111 can be gathered together to reduce the volume of the bracket body 110, which is convenient for storage or carrying. When the insulator bottle support bracket 10 needs to be used, the bracket body 110 can be unfolded, and the two sides of the bracket body 110 can be connected to the screw rod 30 by using the connecting part 122, so that the bracket body 110 can be suspended below the insulator 210. Since adjacent anti-drop rods 111 are flexibly connected, when the bracket body 110 is suspended under the insulator 210, under the action of gravity, the bracket body 110 surrounded by multiple anti-drop rods 111 is an arc-shaped structure, and the curvature of the arc-shaped structure is adjustable. In this way, the insulator bottle support bracket 10 can be suitable for insulators 210 of different sizes, and when in use, each anti-drop rod 111 can be fully fitted with the insulator 210.

[0028] Specifically, when the diameter of the insulator 210 is large, the opening formed by the bracket body 110 is large. When the diameter of the insulator 210 is small, the opening formed by the bracket body 110 is small when the bracket body 110 fits with the insulator 210, and the insulator 210 is wrapped in a large area.

[0029] For details, please continue to see Figure 1 and Figure 2 In this embodiment, the first end and the second end of the anti-drop rod 111 are both provided with a connecting ring 113. Two flexible connectors 112 are provided. One of the flexible connectors 112 passes through the connecting rings 113 on the first ends in sequence, and the other flexible connector 112 passes through the connecting rings 113 on the second ends in sequence. In this way, when the bracket body 110 is suspended under the insulator 210 and the insulator string 20 is placed in the bracket body 110, the anti-drop rod 111 can be prevented from shaking, and the insulator string 20 can be stably supported.

[0030] In order to further improve the stability of the bracket body 110 when supporting the insulator string 20, optionally, in another embodiment, three or more flexible connectors 112 are provided. In this way, the flexible connector 112 and the plurality of anti-drop rods 111 can form a mesh-structured bracket, which can effectively prevent relative shaking between adjacent anti-drop rods 111 when the insulator 210 is placed on the anti-drop rods 111.

[0031] In order to prevent the insulator string 20 from falling from between two adjacent anti-drop rods 111 when the support body 110 supports the insulator string 20, the maximum distance between two adjacent anti-drop rods 111 is smaller than the diameter of the insulator 210. Specifically, the position of the anti-drop rod 111 on the flexible connector 112 is adjustable, so that before disassembling or repairing the insulator 210, the distance between adjacent anti-drop rods 111 in the support body 110 can be adjusted according to the diameter of the insulator 210 to adapt to the replacement of different types of insulators 210.

[0032] Optionally, in another embodiment, the staff may increase or decrease the number of anti-drop rods 111 on the flexible connector 112 according to actual needs.

[0033] Specifically, in this embodiment, the flexible connecting member 112 is a high-strength connecting rope. The anti-drop rod 111 is made of insulating material.

[0034] Please continue reading Figure 1 and Figure 2On the basis of the above embodiment, in one embodiment, the insulator bottle support bracket 10 further includes a connecting mechanism 120. The connecting mechanism 120 is used to connect the bracket body 110 and the screw rod 30. In this way, the connection of the bracket body 110 can be achieved, so that the insulator string 20 can be supported by the bracket body 110 in a relaxed state.

[0035] Specifically, when repairing or replacing the insulator 210, the staff first clamps the fixtures on the three-eye connecting plates at both ends of the insulator string 20, then connects the connecting screw rod 30 and the steel wire between the two fixtures, and then places the bracket body 110 under the insulator string 20 and connects the bracket body 110 to the screw rod using the connecting mechanism 120. In this way, the bracket body 110 can be suspended under the insulator string 20. When it is necessary to replace the insulator 210 or replace the insulator string 20, shake the screw rod to relax the insulator string 20 onto the insulator bottle support bracket 10.

[0036] It should be noted that the fixtures, lead screws, steel wires and other equipment used when replacing the insulator 210 or the insulator string 20 and the coordination relationship between the various equipment are all existing technologies, and the specific principles and processes of the coordination operation of the various components will not be repeated here.

[0037] Furthermore, if Figure 1 and Figure 2 As shown, in one embodiment, the connection mechanism 120 includes a hook 121 and a connection portion 122 connected to each other. The connection portion 122 is connected to the anti-drop rod 111, and the hook 121 is used to hook on the screw rod 30. In this way, the connection between the bracket body 110 and the screw rod 30 is relatively simple and convenient.

[0038] See also Figure 1 and Figure 2 On the basis of the above embodiment, in one embodiment, the connecting portion 122 includes a connecting rod 1221 and a connecting hook 1222 connected to each other. The connecting hook 1222 is detachably connected to the anti-drop rod 111, and the hook 121 is connected to the connecting rod 1221. In this way, when the insulator bottle support bracket 10 is used, the hook 121 connected to the connecting rod 1221 can be first hooked on the screw rod 30, and then the connecting hook 1222 is used to hook the anti-drop rod 111. Alternatively, the connecting hook 1222 is first hooked on the anti-drop rod 111, and then the hook 121 is hooked on the screw rod 30.

[0039] Since the connection hook 1222 is detachably connected to the anti-drop rod 111 , when the bracket body 110 is hung below the insulator string 20 , the staff can rotatably hook two of the anti-drop rods 111 according to actual conditions.

[0040] Optionally, in another embodiment, the connecting portion 122 includes a connecting rod 1221 and a connecting rope connected to each other. When connecting the anti-drop rod 111, the connecting rope can be used to tie the anti-drop rod 111.

[0041] In order to improve the connection strength of the connection mechanism 120 and improve the working safety of the staff, the connection rod 1221, the connection hook 1222 and the hook 121 are all made of insulating metal materials.

[0042] In order to prevent the hook 121 from falling off after being hooked on the screw rod 30 , based on the above embodiment, in one embodiment, a blocking member 123 for closing the opening is provided at the opening of the hook 121 .

[0043] Likewise, if Figure 2 As shown, in order to prevent the anti-drop rod 111 from falling from the opening of the connecting hook 1222 after the connecting hook 1222 is connected to the anti-drop rod 111, in one embodiment, a blocking member 123 for closing the opening is provided at the opening of the connecting hook 1222.

[0044] When the hook 121 is hooked on the screw rod 30, the bracket body 110 is suspended below the insulator string 20, in order to adjust the longitudinal distance between the bracket body 110 and the insulator string 20. Figure 2 and Figure 3 On the basis of the above embodiment, in one embodiment, the connection mechanism 120 further includes a sleeve 124 sleeved outside the connection rod 1221. The side wall of the connection rod 1221 is provided with an external thread, and the inner wall of the sleeve 124 is provided with an internal thread matched with the external thread. The hook 121 is sleeved outside the sleeve 124, and the end of the sleeve 124 close to the connection hook 1222 is provided with a stopper 125 to support the hook 121. In this way, when the sleeve 124 is rotated, the sleeve 124 can move on the connection rod 1221 along the axial direction of the connection rod 1221. Since the hook 121 is sleeved outside the sleeve 124, and the hook 121 and the sleeve 124 can rotate relative to each other, when the hook 121 is connected to the screw rod 30, when the sleeve 124 is rotated, the connection rod 1221 can move along its axial direction. At this time, since the connecting hook 1222 at one end of the connecting rod 1221 is connected to the anti-drop rod 111, the bracket body 110 can have a movement tendency toward or away from the insulator string 20, thereby adjusting the distance between the bracket body 110 and the insulator string 20.

[0045] See also Figure 2 and Figure 3In order to facilitate the staff to adjust the position of the sleeve 124 on the connecting rod 1221, based on the above embodiment, in one embodiment, the insulator bottle support bracket 10 further includes a crank 130. The crank 130 is sleeved outside the sleeve 124 and is used to rotate the sleeve 124. In this way, rotating the crank 130 around the central axis of the connecting rod 1221 can drive the sleeve 124 to rotate on the connecting rod 1221, adjust the position of the sleeve 124 on the connecting rod 1221, and finally adjust the distance between the bracket body 110 and the insulator string 20.

[0046] Furthermore, in this embodiment, the crank 130 includes a handle 131 and a rotating portion 132 connected to each other. The end of the sleeve 124 away from the limiting platform 125 is provided with a plurality of bosses 126 spaced apart along its circumferential direction, and a locking groove 127 is formed between two adjacent bosses 126. The rotating portion 132 is sleeved outside the plurality of bosses 126, and a locking pin 133 is provided inside the rotating portion 132, and the locking pin 133 can move in a direction relatively close to or away from the locking groove 127. When the locking pin 133 is inserted into the locking groove 127, the connecting portion 122 can drive the sleeve 124 to rotate along the central axis of the connecting rod 1221. When the locking pin 133 is withdrawn from the locking groove 127, the connecting portion 122 can idle.

[0047] In order to improve the durability of the handle 131 and the rotating portion 132 , the handle 131 and the rotating portion 132 are both made of insulating metal materials.

[0048] Specifically, when the sleeve 124 needs to be rotated, the lock pin 133 is inserted into the locking groove 127, so that the sleeve 124 can be driven to rotate around the connecting rod 1221 by rotating the rotating portion 132 by holding the handle 131. In order to prevent the handle 131 from accidentally hitting the insulator 210 during the rotation process, when the handle 131 is close to the insulator 210, the lock pin 133 can be withdrawn from the locking groove 127, so that when the rotating portion 132 is rotated in the reverse direction, the sleeve 124 will not rotate accordingly, and when the handle 131 is away from the insulator 210, the lock pin 133 can be inserted into the locking groove 127.

[0049] Optionally, the locking pin 133 may be automatically inserted into or withdrawn from the locking slot 127 by an electronic control system.

[0050] Specifically, in this embodiment, one end of the lock pin 133 is placed inside the rotating portion 132, and the other end extends outside the rotating portion 132 and can be used to manually push the lock pin 133 to insert into or withdraw from the locking groove 127.

[0051] Optionally, in another embodiment, in order to increase the friction between the hand and the handle 131 and the locking pin 133, anti-slip grooves are provided on the handle 131 and the end of the locking pin for hand-holding.

[0052] In order to prevent the connecting hook 1222 from sliding on the anti-drop rod 111 when hooked on the anti-drop rod 111 and affecting the stability of the support of the bracket body 110, based on the above embodiment, in one embodiment, two sets of limiting parts are provided on the anti-drop rod 111 (not shown in the figure).

[0053] In order to avoid collision between the limiting part and the insulator string, the limiting part is provided at both ends of the anti-drop rod 111. Specifically, the limiting part includes two limiting protrusions. A limiting groove is formed between the two limiting protrusions, and the connecting hook 1222 is limited in the limiting groove. In this way, the connecting hook 1222 is clamped between the two limiting protrusions, which prevents the connecting hook 1222 from sliding on the anti-drop rod 111, and at the same time, prevents the connecting hook 1222 from falling off the anti-drop rod 111.

[0054] In order to make the support body 110 suspended under the insulator string 20 in a stable and balanced state, please refer to Figure 1 On the basis of the above embodiment, in one embodiment, four connecting mechanisms 120 are provided. Two connecting mechanisms 120 form a group. The two groups of connecting mechanisms 120 correspond to and are connected to the two anti-drop rods 111 located at both ends of the flexible connecting member 112 one by one.

[0055] Specifically, the two anti-drop rods 111 at both ends of the flexible connector 112 can be respectively referred to as a first connection anti-drop rod and a second connection anti-drop rod. The first connection anti-drop rod is provided with two connection mechanisms 120, and the two connection structures are respectively located at the two ends of the first connection anti-drop rod. The second connection anti-drop rod is also provided with two connection mechanisms 120, and the two connection structures are respectively located at the two ends of the second connection anti-drop rod.
