Description

Technical Field

[0001] This invention relates to the field of port construction, specifically a mobile unloading device. Background Technology

[0002] A port is a transportation hub with facilities and conditions for combined water and land transport, providing a safe place for ships to enter, exit, and berth. Port engineering is the engineering technology for constructing various engineering facilities required for the construction of a port. Port construction refers to the construction activities of buildings and structures within the port area and planned port area for port production and operation, including port infrastructure and other facilities. Usually, the foundation of a port requires the use of a large amount of steel pipe materials to build wharves and foundations. Therefore, the method of transporting steel materials in ports is quite important.

[0003] However, since a large number of steel pipes of different diameters are needed in port construction, the traditional transportation method involves binding the pipes with ropes. When unloading, the steel pipes are prone to slipping and causing danger when subjected to external force after the ropes are removed. Summary of the Invention

[0004] To address the existing problems, the present invention provides a mobile unloading device, which, when used in conjunction with other devices, can effectively solve the problems mentioned in the background art.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] A mobile unloading device includes a transport mechanism. A steel component support is arrayed inside the transport mechanism. Steel pipe components are arranged on the outer side of the steel component support. A corresponding number of turning mechanisms are arrayed on one side of the steel component support at the upper end of the transport mechanism. A lifting mechanism is correspondingly arranged below the turning mechanism on the outer side of the transport mechanism. Each turning mechanism includes a first fixed pulley, a second fixed pulley, and a pulley support. Each lifting mechanism includes a lifting motor and a winding drum. A side support plate is arranged on the side of the transport mechanism away from the turning mechanisms. Auxiliary rollers are installed on the outer wall of the side support plate. A support plate shaft connects the side support plate to the transport mechanism. A second rotating gear is installed at one end of the support plate shaft. A first rotating gear is installed on one side of the second rotating gear on the side surface of the transport mechanism. A rotating motor is connected to one side of the first rotating gear.

[0007] As a further embodiment of the present invention: the first fixed pulley and the second fixed pulley are both rotatably mounted on the inner side of the pulley bracket via a connecting rod, and a lifting rope is connected between the winding drum and the steel pipe component.

[0008] As a further embodiment of the present invention: an upper support frame is provided above the steel component support, and a limit block slot is formed in an annular array on the outer surface of the upper support frame. A hydraulic cylinder is provided on the upper support frame in a number consistent with the number of limit block slots. The hydraulic cylinder is equipped with a rigid tube limit block on the outside of the upper support frame via a telescopic rod.

[0009] As a further embodiment of the present invention: a lead screw is installed on the lower surface of the upper support frame, a bevel gear set is installed on the outer side of the lead screw, and a lifting motor is installed on one side of the bevel gear set located on the inner side wall of the steel component support.

[0010] As a further embodiment of the present invention: the steel component bracket is provided with a support component on the side near the side support plate, the support component including a limiting guide rod, a return spring, and a support frame.

[0011] As a further embodiment of the present invention: a through hole is provided below the limiting guide rod inside the transport mechanism, the support frame is fixedly connected to the limiting guide rod, and the return spring is sleeved on the outside of the limiting guide rod.

[0012] As a further embodiment of the present invention: the lifting motor is rotatably connected to the bevel gear set, and the bevel gear set is rotatably connected to the lead screw.

[0013] As a further embodiment of the present invention: the rigid tube limiting block is engaged with the limiting block slot.

[0014] As a further embodiment of the present invention: the side support plate is rotatably connected to the transport mechanism via the support plate pivot, and the second rotating gear is meshed with and rotatably connected to the first rotating gear.

[0015] As a further embodiment of the present invention: the hoisting motor is rotatably connected to the take-up spool, and the hoisting rope is fixedly connected to the take-up spool.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. When the steering mechanism and the lifting mechanism are used together, they are used to bind and limit the end of the steel pipe component away from the steel component support. When transporting, after the steel pipe component is installed on the outside of the steel component support, the lifting rope is used to limit it, which can facilitate the vertical storage of the steel pipe component inside the transport mechanism and prevent large steel pipes from rolling off during transport.

[0018] 2. When the steel pipe component is tilted and dropped, it will come into contact with and press against the support frame, which will cause the limiting guide rod to press in the direction of the hole, and at the same time, the return spring will be compressed, reducing the downward impact force of the steel pipe component.

[0019] 3. Control the hoisting motor to rotate the winding drum, so that the hoisting rope can provide a pulling support when the steel pipe component rotates after the first and second fixed pulleys turn. At the same time, the rotation motor drives the first and second rotating gears to rotate, so that the side support plate is unfolded for unloading the steel pipe component.

[0020] 4. The lifting motor drives the bevel gear set to control the screw rod to raise and lower, thereby controlling the installation position of the upper support frame inside the steel pipe component. Then, the hydraulic cylinder is used to control the extension and retraction of the steel pipe limit block to control the installation of steel pipe components with different inner diameters, which facilitates the movement, transportation and unloading of a large number of steel pipes of different sizes used in port construction.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.

[0030] In the description of this specification, references to terms such as "this embodiment," "some embodiments," "example," "specific example," or "some examples" indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example, and the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0031] like Figure 1-7As shown, this embodiment provides a mobile unloading device, including a transport mechanism 1. A steel component support 8 is arrayed inside the transport mechanism 1. Steel pipe components 5 are arranged on the outer side of the steel component support 8. A corresponding number of turning mechanisms 6 are arrayed on one side of the steel component support 8 at the upper end of the transport mechanism 1. A lifting mechanism 7 is correspondingly arranged below the turning mechanism 6 on the outer side of the transport mechanism 1. When the turning mechanism 6 and the lifting mechanism 7 are used together, they are used to bind and limit the end of the steel pipe component 5 away from the steel component support 8. The turning mechanism 6 includes: a first fixed pulley 601, a second fixed pulley 602, and a pulley support 603. The lifting mechanism 7 includes: a lifting motor 701 and a winding drum 702. The first fixed pulley 601... Both the second fixed pulley 602 and the second fixed pulley 602 are rotatably installed on the inner side of the pulley bracket 603 via a connecting rod. A lifting rope 703 is connected between the take-up spool 702 and the steel pipe component 5. The lifting motor 701 is rotatably connected to the take-up spool 702, and the lifting rope 703 is fixedly connected to the take-up spool 702. When transporting, after the steel pipe component 5 is installed on the outside of the steel component bracket 8, and then limited by the lifting rope 703, the steel pipe component 5 can be easily stored vertically inside the transport mechanism 1, preventing large-sized steel pipes from rolling off during transport. A transmission track 4 is installed on the lower surface of the transport mechanism 1. The transmission track 4 is better suited to the complex ground environment of port construction than rollers.

[0032] like Figure 1 , 6As shown in Figure 7, an upper support frame 801 is provided above the steel component support 8. Limiting block slots 802 are arranged in a circular array on the outer surface of the upper support frame 801. A hydraulic cylinder 804, with the same number of limiting block slots 802 as the upper support frame 801, is provided on the upper support frame 801. A rigid tube limiting block 803 is installed on the outer side of the upper support frame 801 via a telescopic rod. The rigid tube limiting block 803 engages with the limiting block slots 802. A lead screw 806 is installed on the lower surface of the upper support frame 801. A bevel gear set 805 is installed on the outer side of the lead screw 806. A lifting motor 807 is installed on one side of the bevel gear set 805 located on the inner wall of the steel component support 8. The lifting motor 807 is rotatably connected to the bevel gear set 805, and the bevel gear set 805 meshes with the lead screw 806. A rotating connection is used, with a rotating ear plate 809 installed below the steel component support 8. A feeding shaft 808 is connected between the rotating ear plate 809 and the steel component support 8. The steel pipe component 5 is sleeved on the outside of the steel component support 8. The lifting motor 807 drives the bevel gear set 805 to control the screw 806 to lift and lower, thereby controlling the installation position of the upper support frame 801 inside the steel pipe component 5. The hydraulic cylinder 804 drives the extension and retraction of the steel pipe limit block 803 to control the limiting installation of steel pipe components 5 with different inner diameters. When feeding, the steel component support 8 rotates through the feeding shaft 808 and the rotating ear plate 809 to move the steel pipe component 5 toward the side support plate 2, thus completing the feeding of the steel pipe component 5.

[0033] like Figure 1-5As shown, a side support plate 2 is provided on the side of the transport mechanism 1 away from the steering mechanism 6. An auxiliary roller 3 is installed on the outer wall of the side support plate 2. A support plate shaft 903 connects the side support plate 2 and the transport mechanism 1. A second rotating gear 902 is installed at one end of the support plate shaft 903. A first rotating gear 901 is installed on one side of the second rotating gear 902 on the side surface of the transport mechanism 1. The side support plate 2 is rotatably connected to the transport mechanism 1 via the support plate shaft 903. The second rotating gear 902 meshes with the first rotating gear 901. A rotating motor 9 is connected to one side of the first rotating gear 901. A steel component bracket 8 is provided on the side closer to the side support plate 2, with a support component 10. The support component 10 includes a limiting guide rod 11, a return spring 12, and a support frame 13. A through hole is opened below the limiting guide rod 11 inside the transport mechanism 1. The support frame 13 is fixedly connected to the limiting guide rod 11. Next, the return spring 12 is sleeved on the outside of the limit guide rod 11. When unloading, the steel pipe component 5 is tilted and falls, which will contact and press against the support frame 13. Then, the limit guide rod 11 will press in the direction of the hole, and the return spring 12 will be pressed, reducing the downward impact force of the steel pipe component 5. When it is necessary to unload the transported steel pipe component 5, the hoisting motor 701 is used to control the winding drum 702 to rotate, so that the winding hoisting rope 703 can provide a pulling support when the steel pipe component 5 rotates after the first fixed pulley 601 and the second fixed pulley 602 turn. At the same time, the rotation motor 9 drives the first rotating gear 901 and the second rotating gear 902 to rotate, so that the side support plate 2 is unfolded. Then, the auxiliary roller 3 on the side surface of the side support plate 2 contacts the ground, which can facilitate the overall movement of the transport mechanism 1 and provide unloading for the steel pipe component 5.

[0034] The working principle of this invention is as follows: During transportation, after the steel pipe component 5 is installed on the outside of the steel component support 8, and then limited by the lifting rope 703, the steel pipe component 5 can be easily stored vertically inside the transportation mechanism 1, preventing large-sized steel pipes from rolling off during transportation. The lifting motor 807 drives the bevel gear set 805 to control the screw 806 to raise and lower, thereby controlling the installation position of the upper support frame 801 inside the steel pipe component 5. The hydraulic cylinder 804 drives the extension and retraction of the steel pipe limiting block 803 to control the limiting installation of steel pipe components 5 with different inner diameters. When unloading, the steel component support 8 rotates through the unloading shaft 808 and the rotating ear plate 809 to move the steel pipe component 5 toward the side support plate 2. When the direction is correct, the steel pipe component 5 is unloaded. When unloading, the steel pipe component 5 is tilted and falls, and it will contact and press against the support frame 13. This will cause the limit guide rod 11 to press in the direction of the hole, and at the same time, the return spring 12 will be pressed to reduce the downward impact force of the steel pipe component 5. When the transported steel pipe component 5 needs to be unloaded, the hoisting motor 701 is used to control the winding drum 702 to rotate, so that the winding hoisting rope 703 can provide a pulling support when the steel pipe component 5 rotates after the first fixed pulley 601 and the second fixed pulley 602 turn. At the same time, the rotation motor 9 drives the first rotating gear 901 and the second rotating gear 902 to rotate, so that the side support plate 2 is unfolded for the unloading of the steel pipe component 5.
