Description

Technical Field

[0001] The utility model belongs to the technical field of ships, and in particular relates to a hatch cover for an automated dock unloading hopper. Background Art

[0002] Ship unloading hoppers play a key role in port operations, especially in the loading and unloading of materials such as grain, ore, and sand and gravel. Portal cranes are used to safely and efficiently grab the cargo from the ship and dump it into the hopper. The belt conveyor equipment below the hopper then works in conjunction with other loading and unloading equipment to transfer the materials to designated storage locations, ensuring the efficient operation of the entire loading and unloading process and the safety of the cargo.

[0003] At present, during the loading and unloading operations of ships, the opening and closing of the hopper hatch cover is completed by the collaboration of gantry crane lifting and manual alignment. The opening and closing of each hopper hatch cover requires one gantry crane and two personnel; however, since the gantry crane grab needs to be disassembled and assembled each time the hopper hatch cover is lifted and opened, the opening or closing time of each hopper hatch cover is about 30 minutes. In severe weather conditions such as rain, snow or extreme winds, the operators have to climb up and down the slippery hopper ladder and stand on the hopper top platform more than 10 meters above the ground to cooperate with the gantry crane lifting and alignment, which poses safety hazards such as falling from heights and falling objects from high altitudes. Utility Model Content

[0004] In order to solve the problems raised in the above background technology, the utility model provides an automated dock unloading hopper hatch cover, which has the characteristics of shortening the opening and closing time of the hopper hatch cover and eliminating the safety hazards such as people falling from heights and objects falling from heights.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figure 1-Figure 5 As shown:

[0021] A hatch cover for a ship unloading hopper at an automated terminal comprises a side wall 1, an original platform 11 installed on the top of the side wall 1, and a hopper 2 fixed on the inner side of the side wall 1. A hatch cover 3 for covering its opening is installed on the top of the hopper 2. The hatch cover 3 is a split hatch cover 3 that opens in half. An extended platform 12 is fixedly connected to the top of the original platform 11. A support 13 is fixedly connected between the bottom of the suspended part of the extended platform 12 and the outer side of the side wall 1. By setting the support 13, the stability of the structure of the suspended part of the extended platform 12 can be increased. Tracks 4 are fixedly installed on both sides of the top of the extended platform 12, and a walking assembly 5 is provided on the track 4. A bracket 6 is fixedly connected between the outer side of one end of the walking assembly 5 and the outer side of one end of the hatch cover 3. The top of the extended platform 12 is located at the end position of the track 4 and is fixedly connected to a baffle 8. The outer side of the end of the baffle 8 close to the track 4 is fixedly connected to a crash barrier 9.

[0022] In this embodiment: when it is necessary to open the hatch cover 3, first confirm whether there are foreign objects in the movable range of the hatch cover 3, and then start the walking assembly 5 to drive the bracket 6 and then drive the hatch cover 3 to move, so that the two hatch covers 3 move in opposite directions, thereby opening the hatch cover 3. A power source 7 is installed on the walking assembly 5. The power source 7 can be an explosion-proof motor and a reducer that cooperate to drive the walking wheels of the walking assembly 5 to rotate. When the hatch cover 3 moves and completely exposes the top opening of the hopper 2, the walking assembly 5 can stop working. The baffle 8 is provided to stably install the anti-collision pier 9. The anti-collision pier 9 is made of non-rigid material, preferably rubber. The anti-collision pier 9 can avoid the risk of the hatch cover 3 falling due to excessive movement.

[0023] In an optional embodiment, the top of the hatch cover 3 is composed of two inclined planes, the top of the hatch cover 3 is higher and the two sides are lower, and the joint of the hatch cover 3 is higher than the tail of the hatch cover 3.

[0024] In this embodiment: the hatch cover 3 has a total of five surfaces, including two top surfaces and three side surfaces. The top of the hatch cover 3 is composed of two inclined planes, two side surfaces are connected to the walking assembly 5 through the bracket 6, and the remaining side surfaces are located at the tail of the hatch cover 3. Setting the top of the hatch cover 3 as two inclined planes can prevent rainwater from accumulating on the top of the hatch cover 3.

[0025] In an optional embodiment, a shielding portion 301 is fixedly connected to the outer surface of the docking point of one hatch cover 3, a rubber strip 302 is fixedly connected to the inner side of one end of the shielding portion 301, and a blocking strip 303 is fixedly connected to the outer surface of the docking point of the other hatch cover 3. When the two hatch covers 3 are docked, the blocking strip 303 is located in the space enclosed by the shielding portion 301 and the rubber strip 302.

[0026] In this embodiment: during the docking process of the two hatch covers 3, the other hatch cover 3 will drive the blocking strip 303 to contact the rubber strip 302 and push the rubber strip 302 to deform until the blocking strip 303 passes over the rubber strip 302 and enters the space enclosed by the rubber strip 302 and the shielding portion 301. When encountering rainy or snowy weather, rainwater will first be blocked by the shielding portion 301 to prevent rainwater and snow from entering the docking gap between the two hatch covers 3. Part of the rainwater will flow down along the shielding portion 301. The provided rubber strip 302 can make the rainwater fall along the rubber strip 302. The provided blocking strip 303 will prevent the rainwater falling along the rubber strip 302 from entering the gap between the two hatch covers 3. Then the rainwater will slide down along the inclined hatch cover 3, thereby preventing rainwater and snow from entering the hopper 2.

[0027] In an optional embodiment, a slider 901 is slidably connected to the inner side of the crash barrier 9, a limit switch 903 is fixedly installed at one end of the slider 901, the limit switch 903 extends outward from the outside of the crash barrier 9, and a spring 902 is fixedly connected between the outer side of the other end of the slider 901 and the outer side of one end of the baffle 8.

[0028] In this embodiment: the limit switch 903 can be an explosion-proof mechanical limit switch 903. When the hatch cover 3 moves to completely expose the top of the hopper 2, if the hatch cover 3 continues to move, it may collide with the anti-collision pier 9. Through the set limit switch 903, when the walking assembly 5 drives the hatch cover 3 to move too far through the bracket 6, the walking assembly 5 will first push the limit switch 903, thereby triggering the limit switch 903, so that the limit switch 903 is pressed. After the limit switch 903 is pressed, the power supply to the walking assembly 5 is stopped, and the continued movement of the hatch cover 3 can be stopped in time. When the limit switch 903 fails, the walking assembly 5 continues to move, and the anti-collision pier 9 provided can prevent the hatch cover 3 from falling. Not only that, the limit switch 903 is fixed by the slider 901, and the slider 901 slides relative to the anti-collision pier 9, and the anti-collision pier 9 can The movement of the slider 901 is made more stable, thereby realizing the stable movement of the limit switch 903. The spring 902 is set, and the anti-collision pier 9 can be deformed after the walking assembly 5 collides with the anti-collision pier 9. Similarly, the anti-collision pier 9 can prevent the hatch 3 from falling. The limit switch 903 can prevent the limit switch 903 from being squeezed and damaged by the slider 901 sliding relative to the anti-collision pier 9, thereby realizing the protection of the limit switch 903. That is, when the limit switch 903 receives excessive squeezing pressure, the limit switch 903 can overcome the elastic force of the spring 902 through the slider 901 and enter the interior of the anti-collision pier 9. Therefore, the elastic force of the spring 902 is greater than the triggering pressure of the limit switch 903. That is to say, before the spring 902 is effectively deformed, the spring 902 can provide sufficient support to trigger the limit switch 903.

[0029] In an optional embodiment, the traveling assembly 5 is controlled locally, remotely, or remotely.

[0030] In this embodiment, the control of the traveling assembly 5 can be performed manually through a local control device, or by using a remote controller, or remotely through a wireless signal.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
