Description

Technical Field

[0001] The utility model relates to the technical field of shuttle vehicles, in particular to a double-station shuttle vehicle. Background Art

[0002] Modern high-bay warehouses have a high storage density, and goods of different specifications are stored in boxes or on pallets on corresponding shelves. At present, stackers and shuttles are mainly used at home and abroad to automatically store and retrieve goods in high-bay warehouses. Shuttles are equipped with higher density and relatively lower costs in high-bay warehouses. As the storage density of high-bay warehouses continues to increase, the high-bay warehouse model equipped with shuttles is more widely used. The speed of goods in and out of high-bay warehouses depends on the number and performance of shuttles.

[0003] According to the search, Chinese patent literature, announcement number: CN216888413U, discloses a material picking double-station shuttle car, including a car body, the car body is provided with a load-bearing device, the load-bearing device includes two load-bearing stations, the load-bearing stations are used to carry goods, the car body is provided with a sorting manipulator, and the two load-bearing stations are both located within the working range of the sorting manipulator. Two load-bearing stations are used to pick up goods on the shelves simultaneously or separately, reducing the use of shuttle cars, reducing logistics costs, and improving logistics efficiency. The shuttle car is provided with a sorting manipulator, which can directly pick up one or more required materials from the material box on the cargo position in the warehouse and place them on the material box of the car body, realizing the operation requirements of multiple materials entering and leaving the warehouse at the same time, and no longer needing to pick up the material box as a whole after leaving the warehouse, further improving logistics efficiency.

[0004] However, when the utility model is in use, if the shuttle vehicle has a battery failure inside the densely packed shelf, high temperature and open flames will be generated, which is very dangerous and can easily cause a fire. In addition, the shuttle vehicle cannot be removed in a short time, which increases the difficulty of extinguishing the fire and causes extremely serious losses. Utility Model Content

[0005] 1. Technical issues to be resolved

When the shuttle vehicle battery fails and generates high temperature and open flames, the fire source can be quickly extinguished to reduce losses, thereby solving the above-mentioned technical problems.

[0007] (II) Technical solution

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a double-station shuttle vehicle, comprising a vehicle body, a cover plate is provided on the top surface of the vehicle body, the cover plate is connected to the vehicle body by fixing screws, the upper surface of the cover plate is provided with mutually symmetrical station grooves, the bottom surface of the vehicle body is provided with a base plate, and mutually symmetrical transmission shafts are provided inside the vehicle body, wheels are provided at the left and right ends of the transmission shafts respectively, mutually symmetrical support bars are provided at the upper end of the interior of the vehicle body, and a battery box is provided on the upper surface of the base plate.

[0009] Preferably, auxiliary wheels symmetrical to each other are respectively installed on the left and right side surfaces of the vehicle body, and the auxiliary wheels are connected to the vehicle body via a rotating shaft.

[0010] Through the above technical solution, by setting auxiliary wheels, when the shuttle is located on the track and moves, the auxiliary wheels will slide along the side surface of the track, thereby providing auxiliary effects, thereby improving the stability of the vehicle body and preventing the shuttle from leaving the track.

[0011] Preferably, mutually symmetrical heat dissipation openings are respectively provided at the corners of the outer surface of the bottom plate, two fans are arranged inside the vehicle body, and a heat dissipation plate is arranged on the bottom surface of the battery box.

[0012] Through the above technical solution, by setting up a heat sink, the heat generated by the battery box can be absorbed and transferred to the outside of the shuttle through the heat dissipation port, and the operation of the fan can further improve the heat dissipation effect, thereby avoiding the self-ignition caused by excessive temperature inside the shuttle, thereby improving the safety of the shuttle when in use.

[0013] Preferably, a drive motor is disposed inside the vehicle body, and there are two drive motors in total.

[0014] Through the above technical solution, by setting up two sets of drive motors, when the internal battery spontaneously ignites and causes the circuit of one drive motor to be damaged, the other drive motor will immediately intervene to drive the shuttle vehicle to quickly exit the cargo-dense area, thereby reducing cargo losses.

[0015] Preferably, a sealing plate is connected to the top surface of the battery box, and a sealing strip is provided between the sealing plate and the battery box.

[0016] Through the above technical solution, by providing a sealing plate and a sealing strip, the battery box can be physically isolated from the space inside the vehicle body, so that when the battery spontaneously ignites, the fire source is prevented from further spreading, the loss is reduced, and the service life of the shuttle vehicle is increased.

[0017] Preferably, aerosol is embedded in the center of the lower surface of the sealing plate.

[0018] Through the above technical scheme, by setting up an aerosol, when the aerosol encounters a fire source, the chemical components in the aerosol will undergo a chemical reaction to produce a large amount of inert gases (such as nitrogen and carbon dioxide). These gases will quickly spread in the protection area, reducing the oxygen concentration in the protection area to below the flammable limit, thereby killing the fire source and preventing the fire from spreading. In addition to chemical reactions, the aerosol also utilizes some physical effects. For example, the aerosol is sprayed out in a micronized form to form a layer of cold smoke-like fire extinguishing agent in the protection area. This cold smoke fire extinguishing agent can quickly absorb heat and form a condensation reaction, thereby further achieving a fire extinguishing effect.

[0019] Preferably, a battery seat is provided inside the battery box, and springs are provided on the left and right surfaces and the lower surface of the battery seat respectively.

[0020] Through the above technical solution, the spring is provided to provide a shock-absorbing effect for the battery holder, thereby avoiding a large impact on the internal battery when the vehicle body collides, thereby improving the safety of use.

[0021] Compared with the prior art, the utility model provides a double-station shuttle vehicle, which has the following beneficial effects:

[0022] 1. The utility model can absorb the heat generated by the battery box by providing a heat dissipation plate, and transfer it to the outside of the shuttle car through the heat dissipation port, and the operation of the fan can further improve the heat dissipation effect, thereby avoiding the self-ignition caused by excessive temperature inside the shuttle car, improving the safety of the shuttle car when in use, and by providing two sets of drive motors, when the internal battery spontaneously ignites and causes the circuit of one drive motor to be damaged, the other drive motor will immediately intervene to drive the shuttle car to quickly drive out of the cargo-intensive area, thereby reducing cargo loss.

[0023] 2. The utility model can physically isolate the battery box from the space inside the vehicle body by providing a sealing plate and a sealing strip, thereby preventing the fire source from spreading further when the battery spontaneously ignites, reducing losses and increasing the service life of the shuttle vehicle. In addition, the utility model can provide a shock-absorbing effect for the battery holder by providing a spring, thereby avoiding a large impact on the internal battery when the vehicle body collides, thereby improving safety of use.
