Problems solved by technology

[0002] The cable trench is an underground pipeline for laying power cable facilities. The substations and voltage levels are different. After years of operation and line transformation, new and old cables are mixed in the cable trench. The space in the ditch is limited, and the old cables are laid out, which brings great troubles to the work of new cables passing through the ditch during the equipment transformation process; the conventional method is to use iron wires, insulating rods, etc. to force the new cables into the In the ditch, this

Example Embodiment

[0026] Example 1

[0027] From Figure 1 ~ Figure 2 It can be seen that the technical solution of the present invention includes two sets of outer tube pulley supports 1, traction rope 2, threading tube 3, at least two inner tube pulleys 5, and cone 4;

[0028] The outer tube pulley support 1 includes a support pulley 10 and a support seat 11. The support seat 11 is in a right-angled structure. The inner side of the main body of the support seat 11 is a fixed position on the ground (with a larger horizontal area). The vertical section is used as a stable ground support, the vertical section is stuck on the edge of the ditch cover or the shaft), and the supporting pulleys 10 are respectively fixed on the outside of the angle between the main body of the support base; in the outer tube pulley support 1, at least one set of supporting pulleys 10 is The main power wheel, the main power wheel adopts a wire-controlled hand crank or a ratchet winch. It is also possible to use active whe...

Example Embodiment

[0038] Example 2

[0039] From image 3 It can be seen that the difference between this embodiment and embodiment 1 is that each section of the single sleeve 30 of the threading tube 3 is composed of two arc-shaped plates, that is, the single sleeve 30 is along its centerline direction. It is divided into an upper arc plate 301 and a lower arc plate 302. The upper arc plate 301 and the lower arc plate 302 are hinged on one side, and the other side is connected by a buckle 32 to form an openable structure, which is convenient for disassembly during construction. Install threading pipe 3. The upper arc plate 301 and the lower arc plate 302 can also be made into a detachable structure, and the two arc plates are connected by a buckle. This structural design makes the assembly and disassembly of the threading tube 3 more convenient, and it will not be affected by the length of the external cable of the cable trench during the trenching process. Pulling the traction rope circulating ...

Abstract

The invention relates to a cable laying construction device, in particular to a cable duct penetrating device. The space inside a cable duct is limited, and the novel cable duct penetrating traditional construction mode is low in efficiency, high in difficulty and likely to damage an old cable. According to the technical scheme, the device comprises two sets of outside pipe pulley supporting pieces, a threading pipe, at least two inside pipe pulleys, a traction rope and a cone cover; the threading pipe is formed by connecting multiple monomer sleeves, and in the working state, the two sets ofoutside pipe pulley supporting pieces are located above the two ends of the threading pipe; clamping bases at the two ends of the threading pipe are each fixedly provided with one inside pipe pulley through a support in a clamped mode; the traction rope penetrates through the threading pipe to wind around the inside pipe pulleys and the two sets of outside pipe pulley supporting pieces in sequenceto form annular connection; the cone cover is detachably installed at one end of the threading pipe. The device is simple in structure, convenient to disassemble and assemble, convenient to use and carry, and capable of enabling multiple cables to penetrate through the cable duct at a time, lowering construction difficulty and labor intensity, improving the working efficiency and avoiding the phenomenon that an old cable is damaged in the threading process.

technical field [0001] The invention relates to cable laying construction equipment, in particular to a cable trenching device. Background technique [0002] The cable trench is an underground pipeline for laying power cable facilities. The substations and voltage levels are different. After years of operation and line transformation, new and old cables are mixed in the cable trench. The space in the ditch is limited, and the old cables are laid out, which brings great troubles to the work of new cables passing through the ditch during the equipment transformation process; the conventional method is to use iron wires, insulating rods, etc. to force the new cables into the In the ditch, this operation method has the following defects: (1) the work efficiency is low, time-consuming and labor-intensive, and labor-intensive; Cable knotting phenomenon; (3) Both ends of the cable trench are located in the shaft, so long rods cannot be used for operation, making the construction e...
