Description

Technical Field

[0001] This utility model relates to the technical field of cable pullers, specifically a cable puller for cable laying site. Background Technology

[0002] In some power cable laying sites, multiple construction workers often need to drag the cable by carrying it on their shoulders or pulling it by hand. Because the power cable is relatively thick or its surface is covered with a lot of water and silt, it is not easy for construction workers to hold the cable by hand and it is easy to slip, making it difficult to exert force with their hands. Therefore, cable pullers are needed to pull the cable.

[0003] For example, Chinese utility model patent CN220233989U discloses a cable laying puller, including a device body and further comprising: a placement groove located in the middle of the upper surface of the device body; a pulling mechanism located above the placement groove; a pulling groove located on one side of the placement groove; a moving mechanism located on the lower surface of the device body; an operator fixedly connected to one side of the device body; and a servo motor fixedly connected to the bottom of the device body, with a drive gear fixedly connected to the output end of the servo motor. This utility model, through the provided moving mechanism, provides automatic movement power to the entire device body, effectively improving the efficiency of cable laying and saving the time and manpower required for cable laying.

[0004] However, the existing devices described above are used for cable pulling in places where mechanical equipment cannot be used. When the machinery cannot adapt to the working environment, their practicality is poor, which reduces the effectiveness and scope of use of the devices. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a cable pulling device for cable laying sites that facilitates cable pulling operations in different environments, improves the application range and effectiveness of the device for cable pulling, and enhances its practicality.

[0006] This utility model discloses a cable pulling tool for on-site cable laying, comprising a fixed plate, two protective plates symmetrically fixedly mounted on the top of the fixed plate, a rotating shaft rotatably mounted between the two protective plates, and a roller rotatably mounted between the two rotating shafts. A limiting hole is formed through the outer wall of the roller, and a sliding groove is formed laterally on the outer wall of the roller, communicating with the limiting hole. An annular groove is formed on the outer wall of the roller, communicating with the sliding groove. A fixed rod is fixedly mounted on the outer wall of one of the rotating shafts, and a fixed cylinder is screwed onto the fixed rod. A limiting groove is formed laterally on the outer wall of the fixed cylinder. This cable pulling tool allows the cable to pass through the limiting hole on the roller. After aligning the cable with the chute, the cable is tightly fitted to the annular groove, thus initially fixing the cable to the outer wall of the roller. The cable is then passed through the limiting groove on the fixed cylinder. By rotating the fixed cylinder, the fixing rod and the fixed cylinder are screwed together, and as the fixed cylinder rotates, it contacts the outer wall of the cable, thus stably fixing the cable between the outer wall of the roller and the inner wall of the fixed cylinder, completing the cable fixing. Simultaneously, the cable is pulled by the moving device, facilitating cable pulling operations in different environments, improving the device's application range and effectiveness for cable pulling, and enhancing its practicality.

[0007] Preferably, one end of the outer side wall of the two guard plates is fixedly connected by a baffle, and the outer side wall of the baffle is fixedly installed with a vertical plate by two brackets. The installation of the baffle, brackets and vertical plate makes it convenient for the user to pick up and move the device.

[0008] Preferably, a first pull rod is screwed onto the outer wall of the upright plate, and a second pull rod is screwed onto the first pull rod. A fixing hook is fixedly installed at the other end of the second pull rod. By installing the first pull rod and the fixing hook, it is convenient to carry out mechanized moving operations of the device. By installing the second pull rod, the service length of the first pull rod is extended.

[0009] Preferably, a connecting shaft is rotatably mounted between the two guard plates, and a guide roller is fixedly mounted on the outer wall of the connecting shaft. The connecting shaft and the guide roller, which rotate during operation, come into contact with the cable, facilitating the initial guiding and supporting of the cable.

[0010] Preferably, two limiting plates are symmetrically fixedly installed at both ends of the guide roller. By installing the limiting plates, it is convenient to limit the cable of the guiding operation.

[0011] Preferably, a motor is fixedly installed on the outer wall of one of the rotating shafts, and the motor is fixedly installed on the outer wall of one of the guard plates. By installing the motor, it is convenient to drive the rollers to rotate and to drag the cable.

[0012] Preferably, an inclined plate is fixedly installed on the inner side wall of the fixed cylinder. By installing the inclined plate, it is easy for the fixed cylinder to fit tightly with one end of the cable, thereby improving the fixing effect of the cable on the outer side wall of the roller.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This cable laying field puller allows the cable to pass through the limiting hole on the roller, align the cable with the chute, and then tightly fit the cable with the annular groove, thus initially fixing the cable to the outer wall of the roller. The cable is then passed through the limiting groove on the fixing cylinder. Simultaneously, as the fixing cylinder rotates, the fixing rod and the fixing cylinder are screwed together, and the fixing cylinder contacts the outer wall of the cable, thus stably fixing the cable between the outer wall of the roller and the inner wall of the fixing cylinder, completing the cable fixation. Simultaneously, the cable is pulled by the moving device, facilitating cable pulling operations in different environments, improving the device's application range and effectiveness for cable pulling, and enhancing its practicality.

[0021] like Figures 1 to 4 As shown, this utility model discloses a cable laying field puller. During operation, after the cable passes through the limiting hole 5 on the roller 4, the cable is aligned with the sliding groove 6, and then tightly fitted with the annular groove 7, thus initially fixing the cable to the outer wall of the roller 4. The cable is then passed through the limiting groove 10 on the fixing cylinder 9. Simultaneously, as the fixing cylinder 9 rotates, due to the screw connection between the fixing rod 8 and the fixing cylinder 9, the fixing cylinder 9 contacts the outer wall of the cable, thus stably fixing the cable between the inclined plate 22 on the outer wall of the roller 4 and the inner wall of the fixing cylinder 9, thereby completing the cable fixing. The cable is initially guided by the guide groove 19 on the guide roller 18. When the cable needs to be pulled, the motor 21 is started, and the motor 21 outputs power to drive the rotating shaft 3, roller 4 and the cable on roller 4 to wind around the outer wall of roller 4 and fixed cylinder 9, thereby assisting the cable in pulling. The first pull rod 14 and the upright plate 13 are screwed together. When the cable needs to be mechanically pulled, the fixed hook 16 is fixed to the mechanical equipment that provides power. Through the transmission of the upright plate 13, bracket 12 and baffle 11, the device and the cable are pulled in a synchronized manner.
