Description

Technical Field

[0001] The present application relates to the technical field of high-wire coil transportation, and in particular to an electric lifting coil transport vehicle. Background Art

[0002] In the modern high-speed wire production process, efficient and precise wire processing is one of the key links to ensure production efficiency and product quality. After continuous innovation, high-speed wire production technology has been able to achieve continuous high-speed rolling of wire into coils and packaging. This process involves the coordinated operation of complex mechanical equipment. After the wire is quickly and continuously formed into coils on the laying machine, the subsequent processing steps - that is, the unwinding and rewinding of the wire - have become the key areas of technical optimization.

[0003] After the last coiling process, the wire needs to be safely and smoothly unloaded from the coil rack and transported to the C-hook for external transportation. The process of introducing the wire onto the C-hook not only requires a precise positioning system to ensure a smooth transition of the wire and avoid additional bending or twisting during transportation, but also requires the C-hook to respond quickly to achieve seamless connection. How to achieve precise docking and obstacle-avoiding resetting between the C-hook and the fork coil arm has become a related technical problem that technical personnel in this field urgently need to solve. Utility Model Content

[0004] The device provides an electric lifting coil transport vehicle, and the specific implementation is as follows:

[0005] An electric lifting coil transport vehicle, comprising:

[0006] A translation drive assembly, wherein the winding core is mounted at one end of the translation drive assembly, and a C-shaped hook is suspended at the other end of the translation drive assembly;

[0007] The transfer assembly is slidably connected to the translation drive assembly, the transfer assembly includes a transfer vehicle and a fork coil arm installed on the transfer vehicle through a connecting rod lifting structure, and the translation drive assembly includes a traction chain, and sprockets are respectively engaged on both sides of the traction chain, and both ends of the traction chain are connected to the transfer vehicle, and the transfer vehicle equipped with the wire coil is driven to move in translation through the rotation of the sprocket;

[0008] A tensioning assembly consisting of a second motor and a connecting rod, one end of the connecting rod is connected to any sprocket, and the trigger end of the connecting rod lifting structure is wound and engaged with the traction chain. The tensioning assembly adjusts the tension of the traction chain and acts on the fork coil arm through the connecting rod lifting structure to achieve height adjustment and transportation of the wire coil.

[0009] Based on the above technical solution, dynamic adjustment of the tension of the traction chain is achieved by introducing a second motor and a connecting rod, that is, the lifting and lowering drive of the fork reel arm is triggered by the tensioning operation of the traction chain; the second motor indirectly adjusts the tension of the traction chain by precisely controlling the swing amplitude of the connecting rod, thereby achieving precise vertical lifting of the fork reel arm and precise docking with the C-hook.

[0010] Preferably, the translation drive assembly also includes a guide rail slidably connected to the traveling wheel in the transfer vehicle, and the sprocket is divided into a driving sprocket and a driven sprocket, and the driving sprocket is coaxially connected to the first motor.

[0011] Preferably, at least two rotating rods arranged in parallel are rotatably provided between the transfer vehicle and the bottom of the fork roll arm, and a third sprocket is fixedly provided downwardly on any rotating rod through a crank arm, and the traction chain is meshed with the third sprocket.

[0012] Preferably, the output end of the second motor is connected to a reducer, and the output end of the reducer is connected to one end of the connecting rod.

[0013] Based on the above technical solution, the inclination angle of the connecting rod is adjusted more accurately and slowly through the reducer, the position of the driven sprocket is moved, the position of the third sprocket is moved with the help of the traction chain, and the connecting rod structure of the rotating rod causes the fork roll arm to rise upward.

[0014] Preferably, it also includes a mounting bracket for hanging the C-shaped hook, and the C-shaped hook and the fork reel arm are arranged in a staggered manner, and the openings of the two are in the same direction.

[0016] Preferably, a deflection plate is installed at the position of the traveling wheel of the transfer vehicle, and each proximity switch is arranged vertically, and its detection end acts on the deflection plate.

[0017] Based on the above technical solution, the position of the transfer vehicle is identified by using proximity switches, and multiple proximity switches are installed at key positions of the transfer vehicle (such as the starting point, docking point, reset point, etc.). When specific marks on the transfer vehicle (such as metal sheets, magnetic tags) approach or pass through these switches, the proximity switches sense the presence of objects through electromagnetic fields, photoelectric effects or ultrasonic principles, and then send signals to the control system; after precise triggering, the specific position status of the transfer vehicle can be confirmed, and the start timing of the core rack or tensioning assembly can be accurately controlled; in the prior art, the core rack can be flipped ninety degrees relative to the translation drive assembly through a cylinder and connecting rod structure.

[0018] Preferably, a limit stopper is installed outside the closed side of the fork roll arm.

[0019] Based on the above technical solution, the height of the limit block is not lower than the thickness of the wire coil, and the front end face of the limit block is flush with the inner concave surface of the fork coil arm. By adding the limit block, the wire coil can be effectively prevented from tilting obliquely on the C-shaped fork coil arm.

[0020] In summary, this application includes the following beneficial technical effects:
