Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of steel rolling equipment in the metallurgical industry, and particularly relates to a cross-span transport vehicle. Background Technology
[0002] During the transition between steel coil rolling production lines, annealing production lines, galvanizing production lines, finishing production lines, and packaging production lines, the traditional method is to use an overhead crane to lift the steel coils to the storage area of the subsequent production line after each production process is completed, awaiting entry into the next production process. During the lifting and buffering process, accidents such as collisions between the overhead crane clamps and the steel coils, collisions between the steel coils and the saddle, and collisions between the steel coils and the equipment are prone to occur.
[0003] Overhead transport vehicles can replace gantry cranes to transfer steel coils. However, currently, the power supply method for overhead transport vehicles is mostly based on cables. When the production line is long, the cables are inconvenient to retract and extend, and they affect the movement of the overhead transport vehicle along its trajectory. At the same time, the insulation layer on the surface of the cables is subject to significant wear. Utility Model Content

[0035] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.
[0036] like Figures 1-3 As shown, this embodiment provides a cross-span transport vehicle, including a first rail 1, a second rail 2, and a vehicle body 3; two first rails 1 are provided, and the two first rails 1 are arranged side by side and spaced apart; three second rails 2 are provided, and the three second rails 2 are arranged side by side between the two first rails 1; the three second rails 2 are electrically connected to the three output electrodes of a DC three-phase power supply 4 respectively; the vehicle body 3 has an electric drive component 31 and three sliding contact components 32, and each side of the vehicle body has at least two rail wheels 331, and multiple rail wheels 331 on the same side The electric drive unit 31 is connected to at least one of the rail wheels 331 and is placed on the first rail 1 on the corresponding side. The three sliding contact members 32 are arranged on the car body 3 and distributed at intervals in the left and right direction. The three sliding contact members 32 are electrically connected to the three input electrodes of the electric drive unit 31. The three sliding contact members 32 correspond one-to-one with the three second rails 2. Each sliding contact member 32 slides in contact with the corresponding second rail 2. In this way, the three second rails between the two first rails serve as power supply lines to power the electric drive unit on the car body, so that there is no need to install cables for power supply.
[0037] Specifically, such as Figure 1 and Figure 2 As shown, an even number of rail wheels are provided, and multiple rail wheels are symmetrically distributed on both sides of the vehicle body. Preferably, any two rail wheels that are aligned with each other can be selected to form a wheelset 33. The axles of these two rail wheels can be extended to form a rotating shaft. The electric drive component is a geared motor. The rotating shaft is provided with a sprocket, gear or pulley. The drive end of the electric drive component can be provided with a sprocket, gear or pulley. At this time, the electric drive component can be transmitted to the corresponding rotating shaft through a chain, direct meshing or belt.
[0038] like Figure 1 As shown, in this embodiment, the end of the first rail can be provided with a stop block 11 to prevent the vehicle body from derailing when it moves to the end of the first rail.
[0039] like Figure 2As shown, the DC three-phase power supply 4 in the above technical solution is an AC-DC power module, which is used to convert alternating current into low-voltage direct current; thus, the three second rails are powered by low-voltage direct current, which improves safety. In this embodiment, the sliding contact can be located at the end of either end of the vehicle body.
[0040] Preferred, such as Figure 2 As shown, four rail wheels are provided. The two rail wheels closest to the sliding contact member form a wheelset with the rotating shaft. A through-hole can be provided in the middle of the end of the vehicle body away from the sliding contact member, which can reduce the weight of the vehicle body.
[0041] like Figure 2 and Figure 4 As shown, in the above technical solution, the upper end of the vehicle body 3 is also provided with limiting seats 34 spaced apart along the left and right directions, and the middle of the upper end of the vehicle body 3 is used to place the steel coil 7; in this way, the limiting seats can limit the steel coil to prevent it from rolling off the upper end of the vehicle body; preferably, the limiting seats 34 on both sides are distributed opposite to each other, and the side of the two seats that are close to each other is inclined, and the distance between the two limiting seats 34 gradually decreases from top to bottom; this makes the limiting effect of the limiting seats better. In this embodiment, the limiting groups can be distributed in pairs (two pairs in a row, the two limiting seats in the same pair are distributed left and right apart, while the limiting seats in different pairs are distributed front and back apart). More preferably, the corner side of the limiting seat can also be set as an inclined plane, in which case the cross-section of the limiting seat is a right triangle.
[0042] like Figures 1-3 As shown, the sliding contact 32 in the above technical solution includes a damping rod 321 with conductive properties and a sliding contact head 322. The damping rod 321 is insulatedly mounted on the vehicle body 3 with its telescopic end facing downwards. The sliding contact head 322 is mounted on the telescopic end of the damping rod 321 and slides in contact with the corresponding second rail 2. The damping rod 321 is electrically connected to the corresponding input electrode of the electric drive component 31. This ensures that the sliding contact component can always maintain close contact with the second rail, thereby ensuring the stability of the electric drive component during operation. The damping rod is a metal component (such as a gas spring or a shock absorber rod similar to a compressed spring), while the sliding contact head can be a metal roller or a wear-resistant metal block.
[0043] like Figure 1 As shown, the vehicle body 3 described in the above technical solution is provided with anti-collision blocks 35 at its ends; thus, the anti-collision blocks can protect the vehicle body. In this embodiment, the anti-collision blocks can be made of soft material (similar to the cushions of a sofa), so that the vehicle body has certain buffering characteristics when it collides with other objects, thereby making the safety better (preferably, anti-collision blocks are provided at both ends of the vehicle body).
[0044] The above technical solution also includes a controller 36 mounted on the vehicle body 3, and the electric drive unit 31 is electrically connected to the controller 36; thus, the operating state of the electric drive unit can be controlled by the controller. In this embodiment, the controller can be an ARM series microcontroller or a PLC controller.
[0045] In the above technical solution, the end of the vehicle body 3 is provided with a limit switch 37 that is electrically connected to the controller 36; thus, when the vehicle body collides or comes into contact with other objects during movement, the limit switch senses the signal and the controller controls the electric drive unit to brake for emergency stopping.
[0046] The above technical solution also includes a first communication module 38 disposed on the vehicle body 3 and electrically connected to the controller 36. The first communication module 38 is used to communicate with the terminal device 6. This allows the vehicle body to be remotely controlled by the terminal device. The smart terminal can be a computer or an industrial control computer, and the first communication module can be a 4G / 5G communication module.
[0047] The above technical solution also includes a ranging sensor component 5, which is disposed at one end of the movement trajectory of the vehicle body 3 and is communicatively connected to the terminal device 6 or controller 36. The ranging sensor component 5 is used to monitor the real-time position of the vehicle body 3. In this way, the position of the vehicle body can be monitored in real time through the ranging sensor component, and the vehicle body can be prevented from moving to derailment. In this embodiment, the ranging sensor component can be a ranging radar, which can control the electric drive component to decelerate when it detects the vehicle body approaching, so as to reduce the vehicle speed in advance when the vehicle body moves to the end of the first rail, and avoid excessive speed that could lead to derailment or collision with the stop.
[0048] In this embodiment, the ranging sensing component 5 can be a wired ranging radar, which can be electrically connected to the terminal device via a cable. Alternatively, the ranging sensing component 5 can be a wireless ranging radar, which can communicate wirelessly with the controller (the wireless connection between the controller and the terminal device can be similar to the wireless connection between the controller and the terminal device). Specifically, for wireless communication, both the terminal device and the ranging sensing component need to be matched with a second communication module that can wirelessly transmit signals to the first communication module 38. This is existing technology and will not be elaborated here. The second communication module can also be a 4G / 5G communication module.
[0049] In this embodiment, two first steel rails constitute the movement trajectory of the vehicle body (one end of the movement trajectory is the loading end, and the other end is the unloading end). Preferably, the ranging sensing component can be set only at the unloading end of the movement trajectory.
[0050] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
