Description

Technical Field

[0001] The utility model relates to the technical field of cable embedded laying, in particular to an underground cable embedded laying device. Background Technique

[0002] A cable is usually a cable similar to a rope formed by stranding several or several groups of wires (at least two wires in each group). The wires in each group are insulated from each other and are often twisted around a center. The whole is wrapped with a highly insulating covering layer. The cable has the characteristics of internal power conduction and external insulation. There are power cables, control cables, compensating cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. They are all composed of single-strand or multi-strand wires and insulating layers, and are used to connect circuits, electrical appliances, etc. When laying and embedding cables, a cable laying device is required.

[0003] Most of the current cable laying devices lay cables by rotating the winding roller. When the cable is used up, the winding roller needs to be replaced. The replacement of the winding roller is time-consuming and laborious, resulting in a long replacement time, which affects the subsequent cable laying and reduces the efficiency. For this reason, we propose an underground cable embedded laying device. Content of the Utility Model

[0004] The purpose of the utility model is to provide an underground cable embedded laying device to solve the problem that most of the current cable laying devices lay cables by rotating the winding roller. When the cable is used up, the winding roller needs to be replaced. The replacement of the winding roller is time-consuming and laborious, resulting in a long replacement time, which affects the subsequent cable laying and reduces the efficiency as mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: an underground cable embedded laying device, including a bottom plate, moving wheels, a push handle and a winding roller. The moving wheels are rotatably connected to the four corner edge positions at the bottom of the bottom plate. The push handle is fixedly connected to the right side position at the top of the bottom plate.

A connecting mechanism is fixedly connected to the right side at the top of the bottom plate. The connecting mechanism includes a mounting plate, a rotating shaft, a connecting box, a pull rod, a pulling plate, a tension spring, a connecting block and a fixing hole. The mounting plates are fixedly connected to the right parts of the front and rear sides at the top of the bottom plate. The middle part of the top of the front mounting plate is rotatably connected through a bearing to the rotating shaft. The opposite ends of the rotating shaft are fixedly connected to the connecting box. The pull rod is slidably connected through the right side of the connecting box. The right end of the pull rod is fixedly connected to the pulling plate. The tension spring is sleeved on the outer side of the pull rod.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. When the underground cable pre-buried laying device needs to be replaced after use, the pull plate is pulled to drive the pull rod to move, so that the tension spring is stretched, so that the pull rod is withdrawn from the fixing hole, and the connection block is released, thereby releasing the fixation of the reel for easy disassembly. After that, a new cable reel is installed, so that the connection block is embedded in the connection box, and the pull rod is loosened. The pull rod is driven to be embedded in the fixing hole through the reset of the tension spring to complete the fixation, so that the installation and disassembly of the reel is very convenient, easy to replace, time-saving and labor-saving, so that the overall cable laying efficiency is improved, and the convenience of the device is improved.

[0018] 2. When the underground cable is laid and payed out, the rotating frame is pulled, so that the sliding rod squeezes the compression spring. The cable is passed through between the pressure roller and the guiding roller. The rotating frame is loosened, and through the reaction force of the compression spring, the pressure roller squeezes the cable, thereby preventing the cable from moving around during the cable laying, making the cable laying more stable. At the same time, through the pressing of the pressure roller and the guiding roller, the cable is straightened, thus facilitating the cable laying. Brief Description of the Drawings
