Description

Technical Field

[0001] This utility model relates to the field of gantry crane water cannon technology, and in particular to a gantry crane water cannon cleaning device. Background Technology

[0002] Gantry cranes are large loading and unloading equipment widely used in ports, docks, and freight yards. Since gantry cranes operate outdoors for a long time, dust, oil, and salt spray will accumulate on their structural surfaces, especially on key tracks, traveling mechanisms, or near the operator's cab. In order to ensure the normal operation of the gantry crane and extend its service life, it is particularly important to clean and maintain it regularly.

[0003] Currently, there are some shortcomings in the cleaning of gantry cranes. On the one hand, manual high-altitude cleaning is not only labor-intensive and inefficient, but also poses a high safety risk. On the other hand, existing automated cleaning devices cannot adapt to the large size and complex structure of gantry cranes. The spray angle of these devices is fixed or has a very limited adjustment range, making it impossible to flexibly cover the cleaning areas at different heights and angles of the gantry crane.

[0004] To address this issue, water cannon devices with angle adjustment capabilities have emerged. However, these devices still reveal new problems in practical use. First, to achieve flexible nozzle rotation, their mechanical structure is relatively complex, and the design of the water supply pipeline at the movable joint is a technical challenge. During nozzle angle adjustment, traditional flexible water pipes can twist or bend excessively, affecting water flow and causing leaks due to poor sealing at the joints. Second, the stability of the water supply system directly affects the cleaning effect. Fluctuations in the water pump pressure can cause the water jet from the water cannon to be inconsistent in strength, failing to form a continuous and stable high-pressure water column, thus reducing cleaning efficiency and quality.

[0005] Therefore, this utility model proposes a gantry crane water cannon cleaning device to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems existing in the gantry crane water cannon cleaning device, such as the complex angle adjustment structure, the easy interruption of water supply at the movable connection, the unstable water supply pressure and the easy leakage at the connection, this utility model aims to provide a gantry crane water cannon cleaning device with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a gantry crane water cannon cleaning device, including: a connecting body, a connecting mechanism, an angle adjustment mechanism, a connecting flange, a water supply pump, a suction pipe, and a water inlet pipe.

[0008] The connecting mechanism includes a support cylinder, a water tank, a sealing plate, and a water inlet connector; the angle adjustment mechanism includes a water cannon connecting seat, a rotating center column, a push rod, a rotating slot, a rotator, a corrugated hose, a water delivery inner pipe, and a water cannon nozzle.

[0009] Furthermore, the connecting body, connecting mechanism, angle adjustment mechanism, and water supply system are combined in the following way: the connecting body is fixedly connected to the platform; The connecting flange is located between the connecting mechanism and the angle adjustment mechanism, and connects the connecting mechanism and the angle adjustment mechanism; The water cannon connecting seat is pivotally connected to the rear end of the push rod via a rotating central column. The push rod slides in the rotating slot and is driven by the rotator to rotate within a preset angle range. One end of the corrugated hose is connected to the water cannon connector, and the other end is connected to the water cannon nozzle. The water delivery inner pipe is inserted into the water cannon nozzle. The water supply pump draws water from an external water source through a suction pipe. One end of the inlet pipe is connected to the water supply pump, and the other end is connected to the connecting mechanism through an inlet connector.

[0010] Preferably, a sealing disc is provided at the connection between the connecting flange and the water inlet connector.

[0011] Preferably, the water tank is located inside the support cylinder of the connecting mechanism.

[0012] Preferably, the rotating slot is an arc-shaped slot, and the push rod moves along the trajectory of the arc-shaped slot.

[0013] Preferably, the rotator drives the push rod to move along the rotating slot, causing the water cannon connecting seat to rotate around the rotating center column, thereby changing the spray angle of the water cannon nozzle.

[0014] Preferably, the corrugated hose has telescopic bending characteristics, and the inner water pipe adjusts its position synchronously with the water cannon nozzle.

[0015] Preferably, the water pump draws water through the suction pipe and delivers it to the water tank of the connecting mechanism through the inlet pipe and inlet connector.

[0016] Preferably, the water in the water tank enters the water supply inner pipe of the angle adjustment mechanism and is delivered to the water cannon nozzle.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problems of complex structure and water supply interruption caused by movable connection when adjusting the spray angle in existing cleaning devices by setting up a linkage mechanism in which a rotator drives a push rod, and the push rod moves along the rotating slot to drive the water cannon connecting seat to rotate around the rotating center column. It also uses a corrugated hose and a water supply inner pipe to achieve the technical effect of flexible spray angle adjustment, reliable structure and continuous and stable water supply.

[0018] 2. This utility model solves the problems of unstable water jet caused by fluctuations in external water supply pressure and leakage caused by the connection of multiple parts in existing cleaning devices by integrating a water tank inside the support cylinder of the connecting mechanism and sealing the water inlet with a sealing plate. It achieves the technical effects of stabilizing water flow pressure, improving overall sealing performance, and making the device structure more compact and reliable. Attached Figure Description

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Example

[0022] Please refer to Figures 1 to 4 This utility model provides a gantry crane water cannon cleaning device, which aims to solve the problems of complex angle adjustment structure and insufficient water supply stability of existing cleaning devices.

[0023] like Figure 1 and Figure 2As shown, a gantry crane water cannon cleaning device includes a connecting body 1, a connecting mechanism 4, and an angle adjustment mechanism 3. The connecting body 1 is fixedly connected to an external platform, serving as the installation base for the entire device. The connecting mechanism 4 and the angle adjustment mechanism 3 are fixedly connected via a connecting flange 2. The connecting mechanism 4 includes a support cylinder 41, inside which a water tank 42 is installed, and an external water inlet connector 44 is also provided. A sealing plate 43 is provided at the connection between the connecting flange 2 and the water inlet connector 44. An external water supply system is connected to the connecting mechanism 4. It includes a water supply pump 46, a suction pipe 47, and an inlet pipe 45. The water supply pump 46 draws water from an external water source through the suction pipe 47. One end of the inlet pipe 45 is connected to the water supply pump 46, and the other end is connected to the connecting mechanism 4 through the inlet connector 44. The angle adjustment mechanism 3 is installed at the front end of the connecting mechanism 4 and is used to adjust the pitch angle of the water cannon nozzle 38. The angle adjustment mechanism 3 includes a water cannon connecting seat 31, a rotating center column 32, a push rod 33, a rotating slot 34, a rotator 35, a corrugated hose 36, and a water delivery inner pipe 37.

[0024] Please refer to the following carefully. Figure 3 and Figure 4 The water cannon connecting seat 31 of the angle adjustment mechanism 3 is rotatably connected to the rear end of the push rod 33 via a rotating central column 32. The push rod 33 is slidably engaged with a rotating groove 34, which is an arc-shaped groove. The rotator 35 is driven by the push rod 33 to provide power for the movement of the push rod 33. The push rod 33 moves along the trajectory of the arc-shaped groove, thereby driving the water cannon connecting seat 31 to rotate around the rotating central column 32. This linkage structure ensures that the water cannon nozzle 38 can stably adjust its pitch angle within a preset angle range. At the same time, to ensure continuous water supply during the angle adjustment process... The corrugated hose 36 is fixedly connected at one end to the water cannon connector 31 and at the other end to the water cannon nozzle 38. The corrugated hose 36 has telescopic bending characteristics. The inner water supply pipe 37 is inserted into the water cannon nozzle 38. When the angle of the water cannon nozzle 38 changes, the inner water supply pipe 37 adjusts its position synchronously with the water cannon nozzle 38 to ensure the stability and uninterrupted water supply path. As for the rotary device 35 used to drive the push rod 33, those skilled in the art can use a variety of conventional methods such as motors and hydraulic cylinders. Its specific internal structure is a well-known technology in the field and will not be described in detail here.

[0025] Reference Figure 3 The sealing disc 43 is clamped between the mating end faces of the connecting flange 2 and the water inlet connector 44. Preferably, the sealing disc 43 is made of high-pressure resistant rubber or polytetrafluoroethylene. It is compressed by the fastening force of the connecting flange 2 and the water inlet connector 44, thereby filling the connection gap and preventing high-pressure water leakage. As another preferred embodiment, in order to provide stable water flow buffering, refer to... Figure 3The water tank 42 is disposed within the internal space of the support cylinder 41. The outlet of the water inlet connector 44 is directly connected to the inlet of the water tank 42, and the outlet of the water tank 42 is connected to the beginning of the water supply pipe 37, forming a pressure-stabilizing chamber before the water flows from the water inlet connector 44 into the angle adjustment mechanism 3. As another preferred embodiment, in order to achieve precise and smooth angle adjustment movement, refer to... Figure 4 The rotating slot 34 is specifically configured as an arc-shaped groove machined along a preset trajectory. The push rod 33 is equipped with a slider or roller that cooperates with the rotating slot 34. Driven by the rotator 35, the push rod 33 slides smoothly along the arc-shaped path of the rotating slot 34. This arc-shaped track limiting structure accurately converts the driving force of the rotator 35 into the rotational motion of the water cannon connecting seat 31. As another preferred embodiment, in order to adapt to displacement changes during angle adjustment and maintain water supply, refer to... Figure 4 The corrugated hose 36 is made of a flexible material with telescopic and bending characteristics. The two ends of the corrugated hose 36 are respectively sealed to the outlet of the water cannon connector 31 and the inlet of the water cannon nozzle 38 through clamps or threaded joints. The water delivery inner pipe 37 is adjusted in position synchronously with the water cannon nozzle 38 to ensure that the water flow path remains unobstructed at any spray angle.

[0026] Working principle: The connecting body 1 is used to connect the device to the platform. The connecting flange 2 is used to connect the connecting mechanism 4 and the angle adjustment mechanism 3. The angle adjustment mechanism 3 is installed at the front end of the connecting mechanism 4. The water cannon connecting seat 31 is connected to the rear end rotating slot 34 of the push rod 33 through the rotating center column 32. The push rod 33 cooperates with the rotating slot 34 and is driven by the rotator 35, so it can rotate within a certain angle. One end of the corrugated hose 36 is connected to the water cannon connecting seat 31, and the other end is connected to the water cannon nozzle 38. The water supply inner pipe 37 is inserted into the water cannon nozzle 38 to ensure water flow transmission and angle adjustment. When adjusting the water cannon spray angle, the rotator 35 operates, the push rod 33 moves along the rotating slot 34, and drives the water cannon connecting seat 31 to rotate around the rotating center column 32, changing the angle of the water cannon nozzle 38. The corrugated hose 36 can extend and bend, and the water supply inner pipe 37 adjusts its position synchronously with the water cannon nozzle 38 to ensure uninterrupted water supply. In the connecting mechanism 4, the water supply pump 46 draws water from an external water source through the suction pipe 47. One end of the water inlet pipe 45 is connected to the water supply pump 46, and the other end is connected to the connecting mechanism 4 through the water inlet connector 44. The support cylinder 41 is equipped with a water tank 42. The sealing plate 43 is located at the connection between the connecting flange 2 and the water inlet connector 44 to ensure the sealing when water is flowing. When the water supply pump 46 starts, the suction pipe 47 draws water from the water source, and sends the water into the water tank 42 of the connecting mechanism 4 through the inlet pipe 45 and the inlet connector 44. Then the water enters the water delivery inner pipe 37 of the angle adjustment mechanism 3 and is finally delivered to the water cannon nozzle 38. The device provides a stable water source through the water supply system, the connecting mechanism 4 ensures water flow transfer and sealing, the angle adjustment mechanism 3 enables flexible adjustment of the spray angle, and the cleaning operation is completed through the water cannon nozzle 38.
