Description

Technical Field

[0001] The utility model belongs to the technical field of power cable engineering construction, and particularly relates to a pipe cable laying auxiliary device. Background Art

[0002] Pipe laying refers to the practice of burying pipes underground and then laying cables inside the pipes. The pipes can be made of concrete pipes, plastic pipes, fiberglass pipes, steel pipes, etc., with sharp or rough outer edges. Pipe laying is preferred in areas with dense underground pipe networks and narrow urban roads where excavation is difficult. Pipe laying requires more investment and requires more construction than direct burial. The advantage of pipe laying is that it can reserve space for adding cables in the future by reserving spare pipes, making cable replacement and maintenance easier. Compared with cable trench laying, pipe laying occupies a smaller area, has a more flexible path, saves investment, and is less difficult to construct. Pipe laying is most widely used in outdoor electrical pipe networks in civil buildings.

[0003] At present, most of the low-voltage power cables in the engineering field are laid manually. During the process of laying cables in pipes, the cables are easily damaged by dragging, friction, mechanical factors and other factors. The existing cable laying and installation devices for power construction lack corresponding entrance auxiliary equipment when in use. As a result, when the workers pull the cables, the cables bend down due to gravity at the entrance of the pipe, which can easily cause the cable sheath to directly slide and rub against the edge of the cable pipe, thereby causing the cable sheath to wear, resulting in a decline in cable quality and a safety hazard. Utility Model Content

[0004] The purpose of the utility model is to provide an auxiliary device for laying cables in conduits to solve the problem in the prior art that when installing cables, there is a lack of auxiliary equipment for the cable conduit entrance, which causes damage to the cable sheath and the edge of the cable conduit due to friction, resulting in a decrease in cable quality and a safety hazard.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A cable pipe laying auxiliary device comprises a cable pipe for inserting cables, and is characterized in that a plurality of auxiliary installation blocks are evenly arranged along the circumference at one end of the cable pipe.

[0007] The side walls of all the auxiliary mounting blocks close to the central axis of the cable tube are parallel to the central axis of the cable tube, and at least one rotating device is arranged on the side wall; the space surrounded by all the rotating devices can pass the cable; when the cable passes through the space, it can drive the rotating device in contact with itself to rotate.

[0008] The utility model also has the following features:

[0009] Furthermore, the rotating device is a ball universal wheel or a roller.

[0010] Furthermore, each of the auxiliary mounting blocks is provided with two rotating devices along the axial direction of the cable tube.

[0011] Furthermore, the auxiliary installation block is a V-shaped clamp structure; the cable drain pipe wall is fixedly clamped in a groove of the auxiliary installation block.

[0012] Furthermore, the auxiliary mounting block comprises a top plate, an inclined plate and a bottom plate; the top plate, the inclined plate and the bottom plate are fixedly connected in sequence to form a Z-shaped structure with two grooves.

[0013] The wall of the cable conduit can be clamped in the groove formed by the top plate and the inclined plate, and the groove formed by the inclined plate and the bottom plate is located outside the cable conduit.

[0014] At least one fastening groove is provided on the side wall of the top plate away from the cable duct, and the fastening groove extends along the width direction of the top plate; a cable tie can be installed inside the fastening groove; the cable tie is installed into the fastening grooves at the corresponding positions of all auxiliary mounting blocks at the same time and connected end to end.

[0019] Compared with the prior art, the utility model has the following technical effects:

[0020] (I) The utility model provides multiple auxiliary mounting blocks on the cable conduit, and provides a rotating device on each auxiliary mounting block. When using the device, construction workers can effectively avoid direct contact between the cable sheath and the edge of the cable conduit. When the cable enters the cable conduit, it first directly contacts the rotating device, converting the sliding friction into rolling friction, reducing the friction resistance of the cable sheath, making it easy for subsequent cables to pass through the power conduit, while preventing the cable sheath from being worn, ensuring the quality of the cable and preventing safety hazards.

[0021] (II) The utility model clamps the auxiliary installation block and the cable conduit, and uses cable ties to reinforce and ensure stability. After completing the cable laying construction, the construction personnel only need to remove the cable ties first, and then they can easily remove the auxiliary installation block from the cable conduit opening, making it convenient to remove and recycle the auxiliary installation block from the cable conduit. It is easy to disassemble and can be recycled, saving resource costs, and is suitable for large-scale use and promotion in industry. BRIEF DESCRIPTION OF THE DRAWINGS
