Technical Field
The application relates to the technical field of high-altitude cable connection, in particular to a high-altitude cable connecting device.
Background
The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art.
The power cable is a cable for transmitting and distributing electric energy, and because the cable is mostly erected in the air, the cable swings when windy weather occurs, and the cable swings often cause the cable junction to bear great stress, for the connection of three cables, as shown in fig. 13, which is a connection manner of three cables at high altitude in the prior art, a fixed connection device 9 fixedly connects a first cable 100, a second cable 101, and a third cable 102 together, and the connection manner in the figure needs to pay attention to two problems: firstly, the strength of the fixed connecting device 9 when the cable swings, and the reliability of the connection between the fixed connecting device 9 and the cable; secondly, when the third cable 102 is actually installed, in order to improve the connection reliability, the connection mode in the drawing is often adopted in the existing connection mode, that is, the third cable 102 and the second cable 101 are attached as much as possible, so that the three cables can be more reliably connected and fixed together, but due to the dead weight of the third cable 102, an angle exists between the cable direction of the third cable 102 and the rest cables in the horizontal direction, so that the third cable 102 is bent or bent, and thus the position where the third cable 102 and the fixed connection device 9 are fixed is more easily broken, and the reliability is poor.
For the connection of two cables, the application number is 201911304764.9, and the name is 'a device for conveniently connecting and having a communication prompt for an overhead power cable', the invention discloses a device for conveniently connecting and having a communication prompt for an overhead power cable, which comprises a left mounting frame and a right mounting frame, wherein a left rope pipe is arranged at the front part of the left mounting frame, a right rope pipe is arranged at the front part of the right mounting frame, a sensor is arranged at the front end of the left mounting frame, a guide head is connected to the right end of the right mounting frame, a metal connecting sheet is arranged at the right upper part inside the left mounting frame, a lower sliding block is slidably connected to the front side of the upper part of the left mounting frame, an upper moving block is connected to the upper end of a second spring, and two metal balls are arranged at the upper end of the upper moving block. Penetrate left rope pipe on the left mounting bracket and right rope pipe on the right mounting bracket respectively through the rope, during the operation, only need the pulling rope to make left mounting bracket and right mounting bracket joint through left rope pipe and right rope pipe and direction head and recess to guarantee power cable's fixed connection, this structure has solved current power cable and has connected the problem that the operation is complicated and operate dangerously. However, the following technical problems exist: 1. the left rope pipe and the right rope pipe are required to be parallel, and the left rope pipe and the right rope pipe are installed when the lower ends of the left rope pipe and the right rope pipe face downwards, so that the left rope pipe and the right rope pipe can be guided through the ropes; due to the particularity of high-altitude operation, the high-altitude operation personnel can have the condition of inconvenient operation when ensuring that the left rope pipe and the right rope pipe are parallel; 2. the guide head and the groove are matched to play a role in positioning the left mounting frame and the right mounting frame, but the rectangular groove and the clamping pin are designed to ensure that the matching between the guide head and the groove is not reliable for ensuring the tight connection of the cable, and the cable is easy to shake when swinging; 3. the metal connecting sheet is connected with the wire, and is arranged in the left mounting frame in the patent document, so that on one hand, the sectional area of the metal connecting sheet is limited, and larger current cannot pass through the metal connecting sheet, and on the other hand, the connection reliability between the metal connecting sheet and the wire depends on the connection reliability between the left mounting frame and the right mounting frame, including the installation and matching precision between the left mounting frame and the right mounting frame, and certain difficulty exists for the aerial cable connection operation; 4. through fastening nut fastening with the board, can appear fastening nut not hard up phenomenon because the swing of high altitude cable in strong wind weather, still can take place the not firm problem that drops of cable fastening.
