Among them, gantry cranes (hereinafter referred to as gantry cranes) play a key role in ship loading and unloading operations. However, gantry cranes use grab buckets to grab materials from the various cabins of the ship and place them in the yard at the front of the berth. In this operation link, since there is a certain height between the material and the ground when the gantry crane grab bucket is opened to discharge the material, and considering the wind factor, dust often occurs during the falling process of the material. In particular, the handling of special types of dust-prone cargo is more likely to generate a large amount of dust, causing serious pollution to the operating area and the surrounding yard environment.

BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 It is a structural diagram of a portal crane;
[0011] Figure 2 It is a structural diagram of the portal support of a portal crane;
[0012] Figure 3 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION
[0013] The following will be combined with the drawings in the embodiments to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0014] like Figure 1 The portal crane shown comprises a portal support 1-2, a walking mechanism 1-1 is arranged at the lower part of the portal support, a slewing platform 1-3 is arranged at the upper part of the portal support, a driver's room 1-4, a machine room 1-5 and a boom system 1-6 are arranged on the slewing platform; the boom system comprises a grab 1-7;
[0015] like Figure 2-3 As shown, an intelligent spraying device for a gantry crane includes a water intake device, wherein the water intake device includes a hose reel arranged on a gantry bracket, a water pipe is arranged on the hose reel, a connection port is arranged at one end of the water pipe, and the other end is connected to a water tank 2. When the water tank needs water supply, the water pipe is connected to a water source on the ground to supply water to the water tank. After the water supply is completed, the released water pipe is rewound into the hose reel; thereby, the problem that the working position of the gantry crane is not fixed and the distance between the hose reel and the ground water source changes can be overcome;
[0016] The water tank is set on the platform 1 of the portal support; in this embodiment, the water tank has a capacity of 3m, and is made of stainless steel 304 material welded whole plate, and the water tank is added with an insulation layer. It is equipped with a liquid level gauge, overflow port, heating rod, vertical ladder, inspection port 3, and maintenance and cleaning hole for easy access by personnel. A water level detection device is set in the water tank. When the liquid level is low, the booster pump stops working to protect the booster pump; when the liquid level is low, the signal is fed back to the driver's room to remind the operator to add water; when the liquid level is high, a prompt is issued to stop filling water to avoid overflow after the water tank is full of water.
[0017] The water outlet of the water tank is connected to the booster pump 4. A stainless steel multi-stage centrifugal booster pump is selected to achieve multi-stage adjustment of the water pump output pressure. The system is equipped with a pressure sensor, which can monitor in real time whether the pressure in the pipeline is consistent with the preset pressure to ensure the constant water use of the system.
[0018] The booster pump is connected to the sprinkler 5. The entire sprinkler is mainly composed of a spray gun tube 5-1, a nozzle 5-2, a pitch mechanism 5-3, a horizontal rotation mechanism 5-4, etc. The sprinkler is made of stainless steel. The horizontal rotation and pitch are driven by the DC motor to rotate the gears, and the horizontal pitch angle can be accurately controlled by the control cabinet 6. The PLC, electrical primary and secondary components in the control cabinet are high-quality products such as Siemens, Schneider, and Omron. The settings of the control cabinet and the circuit settings are common knowledge and can be understood and implemented by those skilled in the art, so they will not be elaborated here.
[0019] To ensure normal use in winter, the water intake device, water tank, booster pump and sprinkler are connected by a water pipe 7. An electric heating belt is installed on the outer wall of the water pipe, and the electric heating belt is connected to the control cabinet; an insulation cotton tube is installed outside the electric heating belt. When the temperature is lower than 5°C, the electric heating system is turned on to ensure that the entire system always operates normally in the set optimal operating temperature zone. At the same time, a heating rod is installed in the water tank to prevent the water in the water tank from freezing.
[0020] By real-time and accurate monitoring of water level, pressure, temperature and other signals, the system automatically adds water or stops protection in case of ultra-low liquid level according to changes in the water tank liquid level. When the temperature is below 5°C, the water tank heating and pipeline electric heating tape are automatically turned on to avoid damage to the water pump and motor, freezing and rupture of the pipeline, and other problems, to ensure normal operation of the system.
[0021] The horizontal angle between the cab and the set 0 position is determined by the cab positioning device, and the angle information is output to the control cabinet program to drive the sprinkler device to the same horizontal angle, realize automatic positioning of the spray gun, and achieve land-side follow-up between the sprinkler device and the grab bucket, ensuring that the spraying area is the grab bucket cargo release area.
[0022] By adding a program segment to the door machine control cabinet, the door machine and the device are linked. When the door machine is in the state of opening the bucket to spread cargo, the door machine outputs a start signal to the device to realize unmanned automatic control of the start and stop of the spraying.
[0023] By adjusting the operating mode of an intelligent spray device for a gantry crane, a variety of different functions can be achieved: 1. In automatic mode, the dust suppression needs of non-fixed locations on the site can be met; 2. In manual mode, the dust suppression needs of hopper release can be met; 3. When it is necessary to flush the accumulated materials on the unused grab, the on-site operator can flush the grab at a fixed point through the remote control; 4. When it is necessary to flush the gantry crane trolley and other parts, an external water pipe can be connected in manual mode to clean the gantry crane to save costs.
[0024] By continuously optimizing system control and simplifying functions during actual use, operators can use the spray system with simple operations.
[0025] The above embodiments are provided to persons familiar with the art to implement or use the technical solution of the present application. Personnel familiar with the art can make various modifications or changes to the above embodiments without departing from the idea of the technical solution of the present application. Therefore, the protection scope of the present application is not limited to the above embodiments, but should be the maximum scope of the innovative features mentioned in the claims.
