Description

Technical Field

[0001] This application relates to the field of flatcar cable take-up and release devices, and in particular to a flatcar synchronous take-up and release cable laying device. Background Technology

[0002] Flatcars are primarily used for transporting large or heavy goods such as steel, timber, automobiles, and machinery. They can also be used with the aid of containers to transport other goods. Flatcars are a type of electric rail-guided transport vehicle used within factories. They typically have I-beam-shaped contact rails laid on the ground, and the flatcar is driven by a motor and reducer to move the drive wheels. Flatcars have advantages such as simple structure, ease of use, high load capacity, convenient maintenance, and long service life, making them the preferred transport tool for short-distance, fixed-point transport of heavy objects within and between factory buildings.

[0003] In the case of cable-carrying flatcars, the winding and unwinding of the cable can easily become out of sync with the flatcar's operation. This can lead to the cable becoming loose, tangled, or pulled, which reduces the cable's lifespan, increases maintenance costs, affects the flatcar's operational stability, and reduces its transportation efficiency. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a flatcar synchronous take-up and unwinding cable device.

[0005] This application provides a flatcar synchronous take-up and untake-up cable laying device, which adopts the following technical solution:

[0006] A flatcar synchronous cable winding and unwinding device includes a flatcar body, a drive end disposed at one end of the flatcar body, a driven end disposed at the other end of the flatcar body, a drum disposed on the flatcar body near the driven end, a first transmission assembly, a second transmission assembly, and a cable winding mechanism. The driven end includes a driven shaft rotatably connected to the flatcar body and driven wheels disposed at both ends of the driven shaft. The driven shaft is drivenly connected to the drum via the first transmission assembly. The cable winding mechanism includes a lead screw, a limiting rod, and a mounting block for limiting the cable. Both ends of the lead screw are rotatably connected to the flatcar body. The limiting rod is disposed on the flatcar body. The mounting block is threadedly connected to the lead screw and slidably connected to the limiting rod. A first through hole is provided on the mounting block, through which the cable passes. The drum is drivenly connected to the lead screw via the second transmission assembly.

[0007] By adopting the above technical solution, the drive end drives the flatcar body to move, the flatcar body drives the driven wheel and driven shaft to rotate, and the driven shaft drives the drum to rotate through the first transmission component, so that the cable on the drum is synchronously wound and unwound during the movement of the flatcar body. The drum drives the lead screw to rotate through the second transmission component, and the lead screw and limit rod drive the mounting block to move. The mounting block arranges the cable through the first through hole, so that the cable is evenly wound on the drum, thereby making the cable winding and unwinding process uniform, thus reducing the phenomenon of cable loosening, knotting or being pulled, improving the service life of the cable and the safety and stability of the flatcar body during operation.

[0008] Preferably, the first transmission assembly includes a first sprocket disposed on the driven shaft, a second sprocket disposed on the drum, and a first transmission chain for connecting the first sprocket and the second sprocket, wherein the first transmission chain is engaged with both the first sprocket and the second sprocket.

[0009] By adopting the above technical solution, the driven shaft drives the second sprocket and the drum to rotate through the first sprocket and the first transmission chain, thereby enabling the drum to wind up and unwind the cable.

[0010] Preferably, the second transmission assembly includes a third sprocket disposed on the drum, a fourth sprocket disposed on the lead screw, and a second transmission chain for connecting the third sprocket and the fourth sprocket, wherein the second transmission chain is engaged with both the third sprocket and the fourth sprocket.

[0011] By adopting the above technical solution, the drum drives the fourth sprocket and the lead screw to rotate through the third sprocket and the second transmission chain, thereby causing the lead screw to drive the mounting block to lay the cable.

[0012] Preferably, the first through hole is provided with two mounting shafts and two guide wheels, the guide wheels are rotatably connected to the mounting shafts, and the cable passes through the gap between the two guide wheels.

[0013] By adopting the above technical solution, the guide wheel reduces the wear and tear on the cable during the cable laying process, thereby improving the service life of the cable.

[0014] Preferably, the guide wheel has a limiting groove, and the cable passes through the limiting grooves of the two guide wheels.

[0015] By adopting the above technical solution, the limiting groove limits the cable, so that the cable contacts the guide wheel during the cable laying process. The guide wheel rotates during the cable sliding process, thereby reducing the wear on the cable. The limiting groove improves the guiding effect of the guide wheel on the cable, further reducing the wear on the cable and further improving the service life of the cable.

[0016] Preferably, a cable trench for placing cables is provided on the ground below the flatcar body.

[0017] By adopting the above technical solution, the cable falls into the cable trench during the movement of the flatcar body. The cable trench limits the cable, thereby reducing the phenomenon of the cable getting tangled or pulled on the ground, reducing cable damage, and thus improving the service life of the cable and the operational stability of the flatcar body.

[0018] Preferably, the flatbed car body is provided with a mounting rod for guiding the cable into the cable trench near the driven end. The mounting rod is located above the cable trench and has a guide hole, through which the cable passes.

[0019] Preferably, both the cable trench and the mounting rod are on the same plane as the central axis of the flatcar body.

[0020] By adopting the above technical solution, the mounting rod guides the cable passing through the cable laying mechanism on the drum, so that the cable falls into the cable trench, thereby improving the safety of the cable during the movement of the flatcar body, and thus improving the service life of the cable and the safety and stability of the flatcar body movement.

[0021] In summary, this application has the following beneficial technical effects:

[0022] 1. The drum is connected to the driven shaft via the first transmission component, so that the winding and unwinding of the cable on the drum is synchronized with the movement of the flatcar body. The cable winding mechanism evenly winds the cable on the drum, which further improves the stability of the cable winding and unwinding process, reduces the phenomenon of cable loosening, knotting or being pulled, improves the service life of the cable and the safety and stability of the flatcar body during movement.

[0023] 2. By setting up cable trenches and mounting poles to limit the movement of cables, the damage to cables on the ground is reduced, further improving the service life of the cables. Attached Figure Description

[0031] Driven end 3 includes a driven shaft 31 rotatably connected to the flatcar body 1 and driven wheels 32 fixedly disposed at both ends of the driven shaft 31. The driven shaft 31 is connected to the drum 4 via the first transmission assembly 5. Both ends of the drum 4 are rotatably connected to the flatcar body 1.

[0032] The cable routing mechanism 7 includes a lead screw 71, a limiting rod 72, and a mounting block 73 for limiting the cable 41.

The limiting rod 72 is fixedly mounted on the flatcar body 1, and the lead screw 71 and the limiting rod 72 are arranged parallel to each other. The mounting block 73 is threadedly connected to the lead screw 71 and slidably connected to the limiting rod 72. A limiting hole 74 is provided on the mounting block 73, through which the limiting rod 72 passes. The mounting block 73 is slidably connected to the limiting rod 72 via the limiting hole 74. A first through hole 75 is provided on the mounting block 73, through which the cable 41 passes. The drum 4 is driven by the lead screw 71 via a second transmission assembly 6. Two mounting shafts 76 and two guide wheels 77 are provided in the first through hole 75. The guide wheels 77 are rotatably connected to the mounting shafts 76, and the cable 41 passes through the gap between the two guide wheels 77. A limiting groove 78 is provided on the guide wheel 77, and the cable 41 passes through the limiting groove 78 of the two guide wheels 77.

[0033] The first transmission assembly 5 includes a first sprocket 51 fixedly mounted on the driven shaft 31, a second sprocket 52 fixedly mounted on the drum 4, and a first transmission chain 53 for connecting the first sprocket 51 and the second sprocket 52.
