Description

Technical Field

[0001] This utility model relates to the field of cable laying technology, and in particular to a cable laying traction device for cable laying. Background Technology

[0002] Cable laying refers to the process of laying and installing cables along a surveyed route to form a cable line. Depending on the application, it can be divided into several laying methods, including overhead, underground, underwater, wall-mounted, and tunnel laying. Choosing the appropriate cable laying method is crucial for ensuring the transmission quality, reliability, and ease of construction and maintenance of the line.

[0003] Currently, cable laying methods include manual laying and equipment-assisted laying. Manual laying is quite laborious. In equipment-assisted laying, a reel with the cable is installed on a take-up roller, and the cable is moved and laid by pulling the traction device. However, there is currently no function to lock the reel. When pulling suddenly stops, the reel will continue to rotate due to inertia, causing the cable to be pulled out a longer section. In addition, when not in use, only locking the reel is possible, which has room for improvement. Utility Model Content

[0004] The purpose of this application is to provide a cable laying traction device for cable laying, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: a cable laying traction device for cable laying, comprising a trolley, an inclined plate mounted on the top of the trolley, a support plate fixed on the top of the inclined plate, a side plate fixed at one end of the top of the support plate, a rotating rod rotatably mounted on the outer wall of the side plate, a fixed disc fixedly mounted on the outer wall of the rotating rod, the fixed disc being positioned close to the side plate, a first gear fixed on the outer wall of the fixed disc, the first gear having a hole for the rotating rod to pass through, a second gear rotatably mounted on the outer wall of the side plate meshing with the first gear, and a pawl fixed to the outer wall of the side plate by a torsion spring, the pointed end of the pawl engaging the tooth groove of the second gear.

[0006] Preferably, a screw head is fixed to the end face of the rotating rod, and an installation disc is threaded onto the screw head. The installation disc is removed and threaded onto the screw head. The drum is pressed and fixed by the fixed disc and the installation disc to complete the installation. This method is suitable for pressing drums of different sizes.

[0007] Preferably, a fixing block is fixed at the top of the tray corresponding to the position of the mounting plate, and an mounting arm is installed on the fixing block through an adjusting component. A rotating wheel is rotatably mounted on the mounting arm, and a groove adapted to the rotating wheel is opened on the outer edge of the mounting plate.

[0008] Preferably, the adjusting component includes a worm gear fixed coaxially with the mounting arm, and the fixing block has a hole for the shaft to pass through. A mounting box is fixed to the outer wall of the fixing block. The worm gear is rotatably connected to the inner wall of the mounting box via a shaft. A worm is rotatably arranged inside the mounting box. A turntable is provided on the outer wall of the mounting box, and the turntable is fixed coaxially with the worm. The mounting box has a hole for the shaft to pass through. The worm gear can be rotated to make the worm gear rotate, and the worm gear can swing with the fixed mounting arm, thereby making the turntable cooperate with the slot on the mounting plate. When the mounting plate rotates, the turntable provides a certain support.

[0009] Preferably, the trolley includes a base plate, with movable wheels fixed at the four bottom corners of the base plate, a handle fixed at the top of the base plate away from the rotating rod, and the inclined plate fixed to the base plate.

[0011] In summary, the technical effects and advantages of this utility model are as follows:

[0012] In this invention, the trolley, side plate, support plate, rotating rod, fixed plate, first gear, second gear, and chuck are included. Manually pressing the chuck releases it from the second gear, thus releasing the first gear. Pulling the trolley allows the cable on the rotating rod to rotate and release as the trolley moves, further releasing the chuck. Under the action of the torsion spring, the chuck positions the second gear, and the first gear positions the rotating rod and cable, preventing further cable release. This effectively solves the problems mentioned in the background technology, facilitating cable release and locking, locking the cable-wound drum, and is suitable for pressing drums of different sizes. It eliminates the need for workers to carry and move the cable during installation, saving considerable effort.

[0013] In this invention, a worm gear is rotated to make the worm wheel rotate, and the mounting arm fixed at the same time is oscillating through the worm wheel, so that the rotating wheel and the slot on the mounting plate are engaged. When the mounting plate rotates, the rotating wheel provides a certain support. Attached Figure Description
