Description

Technical Field

[0001] The utility model relates to the technical field of floor-level vehicles, in particular to a new floor-level vehicle used for transporting steel coils. Background Art

[0002] A land vehicle is a vehicle that travels at very low speeds and is often used to carry heavy cargo on construction sites or in special situations. Their features include an extremely low chassis for easy loading and unloading of cargo, and a powerful powertrain for stability and control at low speeds. These vehicles are often used in places such as construction sites, ports, and logistics centers to handle heavy cargo or carry out handling operations in confined spaces.

[0003] Traditional towed cable flatbed trucks used to transport steel coils are powered by cables. As the movement of the vehicle body drags the cables, the flatbed truck needs to be equipped with a cable retracting and releasing mechanism. Not only is the mechanical part prone to failure, but the cables are also subject to long-term wear and tear, posing a risk of electric leakage and high maintenance costs. Utility Model Content

[0004] The utility model aims to provide a new type of horizontal vehicle for steel coil transportation with sliding contact power supply to solve the problems raised in the above background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions.

[0006] A new type of ground vehicle for transporting steel coils comprises a ground vehicle body. A driving wheel, an auxiliary wheel, a driving mechanism and a current collector are arranged at the bottom of the ground vehicle body. The driving mechanism is used to drive the driving wheel to rotate forward and reverse to achieve forward and backward movement. The driving wheel and the auxiliary wheel are respectively fitted and clamped in tracks arranged on the ground. The current collector is fitted and clamped on a busbar arranged on the ground, and a carbon brush body on the current collector is in sliding contact with a conductor on the busbar.

[0007] It can be seen that the current collector can continuously supply power to the entire flat car by continuously contacting the busbar arranged on the ground, replacing the traditional method of directly supplying power with cables. There is no need to set up additional structures for retracting and releasing cables, and it also avoids leakage caused by cable wear. On the other hand, compared with the method of supplying power with batteries in the prior art, the power supply method of the local flat car can be continuous, without the need to stop for charging, and is highly efficient.

[0008] Furthermore, an inner cavity is provided in the body of the ground vehicle, in which an AC / DC converter and a frequency converter are installed, the current collector is electrically connected to the AC end of the AC / DC converter through a wire, the frequency converter is electrically connected to the DC end of the AC / DC converter through a wire, the frequency converter is connected to the control circuit built into the body of the ground vehicle, the busbar is electrically connected to the output end of the transformer, and the input end of the transformer is electrically connected to the transmission cable.

[0009] Electricity with a standard voltage of 380V or 220V is transmitted to the transformer through a transmission cable. The transformer transforms the voltage into a safe voltage of 36V and then transmits it to the busbar. The carbon brush on the collector and the conductive contact on the busbar achieve conductivity and transmit the electricity to the AC / DC converter. The AC / DC converter converts the AC power into DC power and the control circuit is powered by the inverter to ensure power supply safety.

[0010] Furthermore, the driving mechanism includes a bearing shaft, an axle rod, a driving motor and a pulley transmission group. The bearing shaft is installed at the bottom of the vehicle body of the flat-bed truck, the axle rod is rotatably installed on the bearing shaft, the driving wheel is fixedly mounted on the axle rod, the driving motor is fixed at the bottom of the vehicle body of the flat-bed truck, and the output shaft of the driving motor and the axle rod are connected through a pulley transmission group.

[0011] The output shaft of the driving motor drives the shaft rod to rotate through the pulley transmission group, and then drives the driving wheel to rotate, so as to drive the land vehicle to move. The output shaft of the driving motor and the shaft rod are transmitted through the pulley transmission group to realize the segmented arrangement of the output shaft and the wheel axle. Combined with the low center of the land vehicle body, the load-bearing capacity is improved to avoid tipping and rollover.

[0012] Furthermore, a microcontroller and a wireless communication module are installed in the inner cavity. The microcontroller is electrically connected to the drive motor, and the wireless communication module is electrically connected to the microcontroller. The wireless communication module is used for wireless remote control.

[0013] By sending a wireless control signal to the wireless communication module, the wireless communication module receives the signal and transmits it to the microcontroller, which controls the drive motor to rotate forward and reverse and stop working, thereby realizing the forward, backward and stop of the ground level vehicle body, thereby achieving the effect of station docking, and the wireless control method is more convenient and quick.

[0014] Furthermore, the pulley transmission group includes two pulleys and a transmission belt, wherein one pulley is fixed on the output shaft of the driving motor, the other pulley is fixed on the shaft, and the transmission belt is sleeved on the two pulleys.

[0015] The output shaft of the driving motor drives the pulley on it to rotate, and through the transmission belt, it drives another pulley to rotate, and then drives the shaft to rotate. The belt drive system can effectively reduce the vibration and noise during the transmission process. Compared with other transmission methods such as gear transmission, belt transmission can provide smoother power transmission. Belts have a certain elasticity when transmitting power, which means that they can reduce the impact and vibration of transmission to a certain extent, which helps to protect machine parts.

[0016] Furthermore, a loading groove for placing the steel coil is provided on the top of the vehicle body, and the loading groove is in a V shape.

[0017] By arranging a V-shaped loading groove on the top of the floor truck body, the steel coil can be limitedly placed on the floor truck body to ensure the stability of the steel coil during transportation.

[0018] Furthermore, a bearing plate is fixed on the inner wall of the containing tank, and anti-slip grooves are provided on the bearing plate.

[0019] A load-bearing plate with anti-skid patterns is fixed on the inner wall of the loading tank, which can provide stable support for the steel coil. At the same time, the anti-skid patterns have an anti-skid effect, preventing the steel coil from sliding and deviating during transportation, thereby further improving the stability during transportation.

[0020] Furthermore, anchor points for bundling and fixing the steel coils are evenly distributed on the bearing plate.

[0021] The steel coils are bundled with ropes and fixed with anchor points to facilitate the reinforcement of the steel coils.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0023] 1. The utility model utilizes the collector to continuously contact with the busbar arranged on the ground, so as to continuously supply power to the entire flat car, replacing the traditional method of directly supplying power with cables. There is no need to set up an additional structure for retracting and releasing the cables, and it also avoids the situation where the cable wear causes leakage. On the other hand, compared with the method of supplying power with batteries in the prior art, the power supply method of the local flat car can be continuous, without stopping for charging, with high efficiency and reduced maintenance costs.

[0024] 2. The utility model transmits power of V or V standard voltage to the transformer through a transmission cable, and the transformer transforms the above voltage into V safety voltage, and then transmits it to the busbar. The carbon brush body on the collector and the conductive contact on the busbar achieve conductivity, and transmits power to the AC / DC converter, converts alternating current into direct current through the AC / DC converter, and powers the control circuit through inverter inversion to ensure power supply safety.

[0025] 3. The output shaft of the driving motor drives the shaft rod to rotate through the pulley transmission group, and then drives the driving wheel to rotate, so as to drive the leveling vehicle to move. The output shaft of the driving motor and the shaft rod are transmitted through the pulley transmission group to realize the segmented arrangement of the output shaft and the wheel shaft. Combined with the low center of the leveling vehicle body, the load-bearing capacity is improved to avoid tipping and rollover. BRIEF DESCRIPTION OF THE DRAWINGS
