Description

Technical Field

[0001] This utility model relates to the textile field, and in particular to an electric tractor suitable for lifting large rolls. Background Technology

[0002] An electric tractor is an electrically powered handling device that uses a battery or lithium battery as its power source and is driven by an electric motor. It is used to haul goods or vehicles in factories, warehouses, ports, and other locations. It features zero emissions, low noise, and energy efficiency, making it suitable for short-distance indoor and outdoor transportation. Electric tractors are typically equipped with a towing hook or cargo platform, allowing them to tow flatbed trucks, containers, etc., with load capacities ranging from several tons to tens of tons. They are easy to operate, have low maintenance costs, and require no fuel, meeting environmental protection requirements. They are an ideal alternative to traditional fuel-powered tractors in modern logistics and manufacturing.

[0003] A search revealed patent publication number CN219969696U, which discloses an intelligent tractor unit, relating to the field of pollution-free treatment of diseased animals. The intelligent tractor unit includes a circulation pump fixedly connected to one side of its central section, an automatic telescopic traction hook fixedly connected to the bottom of the same side near the circulation pump, a biting component fixedly connected to the other side, and an exhaust pipe fixedly connected to the other side near the automatic telescopic traction hook. Activated carbon is placed inside the exhaust pipe. A chute is provided on one side of the central section of the intelligent tractor unit, with a sealing plate movably connected to the middle of the chute. After sterilizing and deodorizing the diseased animals in the intelligent tractor unit using the circulation pump, the pump is activated to circulate the airflow within the unit, effectively removing the pungent odor produced by the accumulated rotting and decaying diseased animals. The internally circulated gas is filtered and adsorbed by the activated carbon before being discharged through the exhaust pipe, improving the practicality of the device.

[0004] While existing technologies can achieve a certain level of pipe transport, they suffer from drawbacks: the current tractors lack the capability to transport pipes of different sizes, making it impossible to transport some large pipes and affecting work efficiency. In view of this, we propose an electric tractor suitable for large roll lifting, which solves the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the problems existing in the background technology by proposing a suitable electric tractor for large-roll lifting.

[0006] The technical solution of this utility model is as follows: A large-roll lifting electric tractor includes a base, a rotating column, a first limiting block and a second limiting block. A box is provided on one side of the upper end of the base. A rotating column is rotatably installed on the upper end of the box. A guide rail is provided on one side of the box. A first limiting block is provided on the upper end of the guide rail. A second hydraulic cylinder is provided on one side of the first limiting block. Second limiting blocks are provided on both sides of the second hydraulic cylinder.

[0007] When using this device, the tube to be transported can be placed between limit block one and limit block two. The distance between limit block two can be adjusted using a two-way hydraulic cylinder two to ensure the stability of the tube after placement. The device can use control buttons to control hydraulic cylinder one and hydraulic cylinder three to adjust the height of limit block one and limit block two respectively (the height can also be adjusted simultaneously) to transport different tubes. There are usually disc protrusions on both sides of the tube, so the diameter of the middle part of the tube will be smaller than the diameter of the disc. If the height is not increased, there will be a problem of transportation failure. The length of the handle can be adjusted using screws and limit holes. The rollers are driven by an internal electric drive device. This device has a flexible tube transport effect and is highly practical.

[0008] Preferably, the base is provided with casters on both sides, the box is provided with an electrical control system, and the box is provided with a cover plate on one side. The caster design facilitates flexible movement of the device to adapt to the needs of different workstations.

[0009] Preferably, a hydraulic cylinder is fixed to the upper end of the base, and a hydraulic rod is provided at the upper end of the hydraulic cylinder. The upper end of the hydraulic rod is fixedly connected to the lower end of the limiting block, and the hydraulic cylinder drives the limiting block to rise and fall vertically.

[0010] Preferably, a hydraulic cylinder three is fixed to the upper end of the base, a hydraulic rod three is fixed to the upper end of the hydraulic cylinder three, a fixing block is fixed to the upper end of the hydraulic rod three, and the hydraulic cylinder two is embedded in the fixing block. The hydraulic cylinder three adjusts the horizontal height of the hydraulic cylinder two as a whole through the fixing block to achieve dynamic adaptation of the limiting block two.

[0011] Preferably, the hydraulic cylinder is provided with hydraulic rods on both sides, one side of the hydraulic rods is fixedly connected to one side of the limiting block, and the two-way hydraulic rods push the limiting block synchronously.

[0012] Preferably, the outer wall of the base is provided with control buttons, which control the start and stop of hydraulic cylinder one, hydraulic cylinder two and hydraulic cylinder three. The centralized button control simplifies the operation process.

[0013] Preferably, a rod is inserted into one side of the rotating column, a handle is fixed to one side of the rod, a limiting hole is provided on the surface of the rod, a screw is provided on one side of the rotating column, and the screw is threadedly connected to the limiting hole. The adjustable handle length can adapt to the needs of different operators.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] I. This utility model, through the synergistic action of limiting block one and limiting block two, can adapt to pipes of different diameters. Hydraulic cylinder two enables bidirectional adjustment to prevent the pipe's center of gravity from shifting and ensure the stability of the pipe clamping. The independent or synchronous control of hydraulic cylinder one and hydraulic cylinder three can quickly adjust the height of the limiting blocks, solving the problem of conveying jamming caused by the protrusion of the disc, and significantly improving conveying efficiency.

[0016] II. Based on the first beneficial effect, this device solves the problem of conveying pipes with disc protrusions by controlling the height and spacing of the limit blocks in a coordinated manner with multiple hydraulic cylinders, and has both flexibility and stability. The electrical control system and modular design improve the ease of operation, while the rollers and adjustable handles further expand the application scenarios. The overall structure is compact and the functions are comprehensive. It can significantly reduce the intensity of manual intervention and is suitable for diverse industrial pipe conveying needs, and has high practicality.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
