Detailed Implementation
[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0020] Please see Figure 1-3 One embodiment of this utility model is a cable tray laying traction device, including a movable base 4. A supporting main frame 17 is welded and fixed to the upper surface of the movable base 4. Fixed shafts 8 are installed on both sides of the supporting main frame 17. A cable traction drum 2 is installed on the fixed shafts 8. A limiting traction frame 3 is installed at the outlet end of the cable traction drum 2. The limiting traction frame 3 is used to pull out the cable wound on the surface of the cable traction drum 2.
[0021] Furthermore, a fixed baffle 16 is installed on the limiting traction frame 3. The front end of the fixed baffle 16 is fixedly connected to the discharge box 14 by welding. The discharge box 14 has a slot structure 15 inside. One end of the fixed baffle 16 is fixedly connected to the supporting main frame 17 by bolts. With the limiting traction frame 3 installed for easy assembly and fixing, the cable coming out from the cable traction machine barrel 2 passes through the slot structure 15 inside the discharge box 14 for discharge. This allows for the traction and specification of the cable laying trajectory, preventing the cable from derailing or deviating.
[0022] Furthermore, a roller structure 12 is installed inside the cable traction drum 2. A first limiting chuck 11 is provided at one end of the roller structure 12, and a second limiting chuck 13 is provided at the other end of the roller structure 12. A handwheel structure 7 is welded and fixed to the outer surface of the second limiting chuck 13. A shaft hole structure 10 is provided inside the cable traction drum 2. The cable traction drum 2 is connected to a fixed shaft 8 through the shaft hole structure 10. The operator rotates the handwheel structure 7 by hand, thereby driving and controlling the cable traction drum 2 to rotate, which is convenient for the rapid winding and pulling of the cable. The first limiting chuck 11 and the second limiting chuck 13 play a good limiting role and are used to support both sides of the cable.
[0023] Furthermore, there are four fixed shafts 8 in total. One end of the fixed shaft 8 is connected to the main support frame 17 through the locking member 9, which is used to quickly install and fix the fixed shaft 8.
[0024] Furthermore, a toolbox 5 is installed on one side of the main support frame 17. The rear surface of the toolbox 5 is fixedly connected to the main support frame 17 via a mounting bracket 18, which facilitates the quick installation and fixation of the toolbox 5.
[0025] Furthermore, casters 6 are installed at the four corners of the bottom of the mobile base 4, and a push handle 1 is welded and fixed to the upper end of the mobile base 4. By holding the push handle 1, the equipment on the mobile base 4 can be moved flexibly, which is convenient for laying and pulling cables.
[0026] Working principle: During use, a support frame 17 is welded and fixed to the upper surface of the movable base 4. Fixed shafts 8 are installed on both sides of the support frame 17, and a cable traction drum 2 is mounted on the fixed shafts 8. The operator rotates the handwheel structure 7 to drive the cable traction drum 2 to rotate, facilitating rapid cable winding and traction operations. The first limit chuck 11 and the second limit chuck 13 provide good limiting function, supporting the cable on both sides. A limit switch is installed at the cable outlet end of the cable traction drum 2. The traction frame 3 is equipped with a fixed baffle 16. The front end of the fixed baffle 16 is fixedly connected to the discharge box 14 by welding. The discharge box 14 has a slot structure 15 inside. One end of the fixed baffle 16 is fixedly connected to the main support frame 17 by bolts. With the installation of the conveniently assembled and fixed limiting traction frame 3, the cable exiting from the cable traction machine barrel 2 passes through the slot structure 15 inside the discharge box 14 for discharge. This allows for the traction and specification of the cable laying trajectory, preventing the cable from derailing or deviating.
