Description

Technical Field

[0001] This application relates to the technical field of electric power construction tools, and particularly to a jumper support device. Background Art

[0002] The 35kV line is an important part of China's distribution lines. It has characteristics such as a larger transmission capacity and smaller line losses compared to the 10kV distribution line, and is an important voltage level for the urban suburban and rural power supply networks in China. The structural feature of the 35kV line is that its strain jumpers generally use suspension insulator strings for transition connection, and the distance between the strain jumper and the tower body is relatively small. It is difficult for operators to control the distance from the strain jumper when operating near the crossarm. Therefore, for live working on the 35kV line, it is usually necessary to expand the strain jumper outward by a certain distance to improve the safety of live working. Although there are existing support devices applied to the support of strain jumpers, the operation is relatively cumbersome and the safety is low. Summary of the Invention

[0048] An embodiment of the present application discloses a jumper support device.

[0049] See alsoFigure 1 and Figure 2 An embodiment of a jumper support device provided in an embodiment of the present application includes:

[0050] A first support member 1, a first connecting member 2, a second connecting member 5, a pulley 3, and an insulating rope 4; the first connecting member 2 is installed on a tower bracket 8; a first end of the first support member 1 is connected to a first end of the first connecting member 2 that extends upward from the tower bracket 8, and the first support member 1 is arranged to incline upward in a direction away from the tower bracket 8; the pulley 3 is installed on the first support member 1 at a position away from the first end of the first support member 1; the insulating rope 4 cooperates with the pulley 3, a first end of the insulating rope 4 passes around the pulley 3, and is connected to a tension jumper 7 through the second connecting member 5.

[0051] Specifically, the tower bracket 8 can be a conventional tower angle steel bracket, and the structural design of the first connecting member 2 can be designed according to the angle steel structure. For example, as shown in Figure 1 and Figure 2 , the first connecting member 2 can include a main seat (not shown in the figure) provided with a slot for inserting a first side of the angle steel bracket and a slave seat that is detachably fitted with the main seat through fasteners such as bolts and is provided with a slot for inserting a second side of the angle steel bracket, so as to be fixedly installed on the angle steel bracket. The above is a specific application example of the present application, and there is no specific limitation. Those skilled in the art can make appropriate changes based on this. Similarly, the second connecting member 5 can achieve the connection between the insulating rope 4 and the tension jumper 7, and there is no specific limitation. In addition, in this embodiment, the first support member 1 is arranged to incline upward in a direction away from the tower bracket 8, aiming to ensure that when the insulating rope 4 is pulled, the tension jumper 7 can be supported in a direction away from the tower bracket 8 to achieve the support purpose. The installation angle of the first support member 1 is not specifically limited and can be appropriately changed according to actual needs. Furthermore, the pulley 3 can be, for example, as shown in Figure 1 , hooked and installed on the first support member 1. A hanging member (not shown in the figure) that can be adjusted and used for installing and fixing the pulley 3 can be provided on the first support member 1. The hanging member can be sleeved on the first support member 1 and installed and fixed through fasteners such as wing nuts, and a hanging hole (not shown in the figure) that cooperates with the hook of the pulley 3 is provided on the corresponding hanging member. Similarly, the above means are also one of the specific application examples, and there is no specific limitation. When in use, after pulling the insulating rope 4 to support the tension jumper 7 for a certain distance, the second end of the insulating rope 4 can be fixed to ensure that the tension jumper 7 does not maintain a supported state, facilitating subsequent live working. The overall operation is simple and convenient to use.

[0052] The above is Embodiment 1 of a jumper support device provided in an embodiment of the present application. The following is Embodiment 2 of a jumper support device provided in an embodiment of the present application. For details, please refer to Figures 1 to 5 .

[0053] A jumper support device, comprising: a first support member 1, a first connecting member 2, a second connecting member 5, a pulley 3 and an insulating rope 4; the first connecting member 2 is installed on the tower bracket 8; the first end of the first support member 1 is connected to the first end of the first connecting member 2 that extends upward from the tower bracket 8, and the first support member 1 is inclined upward in a direction away from the tower bracket 8; the pulley 3 is installed on the first support member 1 at a position away from the first end of the first support member 1; the insulating rope 4 cooperates with the pulley 3, the first end of the insulating rope 4 passes around the pulley 3, and is connected to the strain jumper 7 through the second connecting member 5.

[0054] Further, as Figure 1 and Figure 2 shown, the first support member 1 includes a first support rod 11 and a first connecting head 12; the first connecting head 12 is sleeved and fixed on the first end of the first support rod 11 and is connected to the first end of the first connecting member 2. Among them, the first connecting head 12 may be provided with two symmetrically arranged clamping blocks 121; the first end of the second connecting member 5 is provided with a connecting block 21; the connecting block 21 is provided with a first mounting hole (not shown in the figure) and a second mounting hole 211 spaced from the first mounting hole; the clamping blocks 121 form a slot for the connecting block 21 to be inserted movably, and the clamping blocks 121 are respectively provided with a third mounting hole 1211 for cooperating with the first mounting hole and a fourth mounting hole 1212 for cooperating with the second mounting hole 211. By using fasteners such as bolts to fix the first mounting hole and the third mounting hole 1211 and the second mounting hole 211 and the fourth mounting hole 1212 respectively, the installation and fixation of the first connecting head 12 and the first support member 1 can be completed; the installation and fixation are convenient, and the disassembly and maintenance are simple.

[0055] Further, as Figure 2 shown, the number of the second mounting holes 211 is multiple; the multiple second mounting holes 211 are spaced along an arc trajectory with the first mounting hole as the center. Such a structural layout can make the second mounting holes 211 be equidistantly and arc-shapedly distributed around the first mounting hole. When installing and fixing with the first connecting head 12, different angular installations can be realized by selecting different second mounting holes 211 to cooperate with the first mounting hole, and the installation is more flexible and the applicability is better.

[0056] Further, as Figure 2 shown, it further includes a second support member 6 and a locking assembly; the second support member 6 is rotatably connected to the second end of the first connecting member 2 that extends downward from the tower bracket 8 through the locking assembly, and the first end of the second support member 6 is connected to the strain jumper 7.

[0057] Specifically, in this embodiment, the second support member 6 is connected to the strain jumper 7 and rotatably connected to the first connecting member 2 through a locking component, achieving a rotational locking effect. When the strain jumper 7 is supported and opened, the second support member 6 can be driven to rotate around the second end of the first connecting member 2, and the locking component is used for locking, so as to realize the limiting and locking of the strain jumper 7 after being supported and opened by the second support member 6, avoiding the reset of the strain jumper 7 caused by misoperation. The operation is more convenient and safe.

[0058] Further, the second support member 6 may include two second support rods 61 and a rotating rod; the rotating rod is installed between the second support rods 61 and is rotatably connected to the second end of the first connecting member 2 through a locking component; the first end of the second support rod 61 is connected to the strain jumper 7. Among them, setting two second support rods 61 can improve the connection stability with the strain jumper 7 compared with a single second support rod 61. The rotating rod can be connected and fixed to the second support rod 61 through a corresponding rod connecting member, which is convenient for subsequent disassembly and installation. When the insulating rope 4 drives the strain jumper 7 to move, the second support member 6 can also be driven to rotate around the second end of the first connecting member 2, and the locking component is used to realize the locking after rotation.

[0059] Further, similar to the structure of the first support rod 11, the first end of the second support rod 61 is provided with a second connecting head 62; the second connecting head 62 is provided with a clamping hole (not shown in the figure) for the strain jumper 7 to pass through. The connection and fixation between the second connecting head 62 and the strain jumper 7 are realized by using this adjustable clamping hole, which is convenient for installation and disassembly.

[0060] Further, a screw 611 is rotatably arranged in the second support rod 61; the first end and the second end of the screw 611 respectively extend out of the first end and the second end of the second support rod 61; the second connecting head 62 includes a fixing seat 621 rotatably sleeved on the screw 611 and a limiting block 622; an avoidance notch for the strain jumper 7 to pass through movably is formed on the fixing seat 621; the first end of the screw 611 is synchronously rotatably connected to the limiting block 622 and is used for driving the limiting block 622 to move along the direction of the avoidance notch, so that a clamping hole is formed between the limiting block 622 and the avoidance notch.

[0061] Specifically, to implement this adjustable clamping hole technical solution, the second connector 62 can include a fixed seat 621 rotatably sleeved on the screw rod 611 and a limit block 622 connected to the first end of the screw rod 611. By rotating the screw rod 611, the relative movement between the screw rod 611 and the fixed seat 621 can be achieved, thereby driving the limit block 622 to move along the direction of the avoidance notch of the fixed seat 621 to clamp and fix the wire. In this embodiment, the fixed seat 621 can be in a hook shape, and there is no specific limitation. Furthermore, in this embodiment, in order to make the rotation of the screw rod 611 more convenient, an anti-slip sleeve 612 can be fixedly sleeved on the second end of the screw rod 611 to facilitate the operator to rotate the screw rod 611. In addition, the structure of the second connecting member 5 in this embodiment can be installed and fixed to the second connector 62 of the second support rod 61 to achieve the connection with the strain jumper 7; specifically, the structure of the second connecting member 5 can be, for example Figure 3 As shown, it has a connecting portion in the middle, and connecting rod portions at both ends of the connecting portion. The connecting rod portions are installed and fixed to the mounting lugs 623 on the fixed seat 621 through fasteners such as bolts, and the insulating rope 4 can be directly connected to the connecting portion in the middle or connected to it through components such as hooks, without specific limitation.

[0062] Furthermore, as Figure 4 and Figure 5 shown, the locking assembly can be a conventional pawl 91 and ratchet 92 cooperation assembly, which can achieve locking functions such as self-locking. Specifically, the locking assembly can include a ratchet 92 and a pawl 91 cooperating with the ratchet 92; a pivot hole (not shown in the figure) for the rotating rod to pass through is provided inside the second end portion of the second connecting member 5; a locking assembly avoidance cavity 22 is opened at the middle position inside the pivot hole; the ratchet 92 is fixedly sleeved on the rotating rod and is located inside the locking assembly avoidance cavity 22; the pawl 91 is rotatably arranged inside the avoidance cavity, and the teeth of the pawl 91 are movably embedded in the tooth grooves of the ratchet 92, and are used for locking the rotation of the ratchet 92 when the rotating rod has a reset rotation tendency when the strain jumper 7 is in a supported state.

[0063] Specifically, with regard to the above-mentioned technical means, the pawl 91 can be pivotally arranged in the avoidance cavity 22 of the locking assembly, and use its own gravity or elastic parts to make the claw teeth of the pawl 91 have a movement tendency to be actively engaged in the tooth grooves of the ratchet 92. At the same time, when the insulating rope 4 drives the support of the tension jumper 7, the pawl 91 will not affect the rotation of the ratchet 92, that is, it will not affect the rotation of the second support member 6 around the second end position of the first connecting member 2; and when the tension jumper 7 is stretched to a certain position, the ratchet 92 has the function of resetting and rotating under the action of the tension jumper 7, and the pawl 91 limits the rotation of the ratchet 92. The specific structure can be as follows: the pawl 91 is provided with a limit extension 911 and a toggle extension 912; the limit extension 911 and the toggle extension 912 are respectively movable and extended out of the locking assembly avoidance cavity 22; when the rotating rod has a tendency to reset and rotate, the limit extension 911 contacts and abuts against the second end position of the first connecting member 2 to lock the rotation of the pawl 91; through this structural design, even if the rotation of the ratchet 92 has a driving force on the pawl 91, the limit extension 911 on the pawl 91 contacts and abuts against the second end position of the first connecting member 2 at this time, realizing the limit fixation of the position of the pawl 91, so that the pawl 91 can lock the rotation of the ratchet 92 to complete the locking process. Of course, if you want to achieve reset, you can manually pull the insulating rope 4 again, and push the toggle extension 912 through the operating rod, so that the claw teeth of the pawl 91 withdraw from the tooth groove, and then release the insulating rope 4, and the tension jumper 7 can be reset at this time. In this embodiment, a handle 913 can be fixed on the toggle extension part to facilitate the pushing of the operating rod and play a certain anti-slip role. Of course, an electric push rod can also be provided and connected to the toggle extension part through a spring to realize the electric control of the movement of the toggle extension part, which can reduce the manual operation of the operating rod and improve the convenience of operation. The above is one of the application embodiments of this application, which is not specifically limited and can be appropriately changed based on this.

[0064] It can be seen from the above technical solutions that the present application sets a first support member 1 tilted upward in a direction away from the pole tower support 8 on the pole tower support 8 through the first connecting member 2 to facilitate the installation of the fixed pulley 3, and utilizes the cooperation between the insulating rope 4 and the pulley 3 to support the tension jumper 7 in a direction away from the pole tower support 8 by pulling the insulating rope 4. The overall operation is simple and easy to use.

[0065] The above is a detailed introduction to a jumper support device provided by the present application. For a person skilled in the art, according to the idea of the embodiments of the present application, there may be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
