Description

Technical Field

[0001] This invention relates to the field of object transfer technology, and more particularly to transfer equipment. Background Technology

[0002] Currently, the transfer of items on drilling platforms typically uses non-powered flatbed carts, which are pushed manually. When items need to cross steps, manual assistance is required from lifting equipment to raise and lower both the items and the transport equipment, making the entire process time-consuming and labor-intensive.

[0003] To address this, existing technology provides a transfer cart with a front support and a height-adjustable rear support fixedly connected to the bottom of the cart. The rear support is height-adjustable, and the front support is shorter than the rear support. When encountering a step, the height of the rear support is first adjusted, then the item to be transferred is placed on the cart. Workers push the cart by the handle, at which point the wheel on the rear support touches the ground. When crossing a step, the rear support wheel acts as a fulcrum, lifting the small front roller so that it contacts the upper surface of the step. However, this solution still requires manual operation of the transfer cart to cross steps. Furthermore, crossing steps can easily cause the mounting surface of the item to tilt, leading to the item falling. Summary of the Invention

[0004] According to one aspect of the present invention, the present invention provides a transfer device to solve the problem in the prior art that manual operation of a transfer vehicle is required to cross steps, and that the mounting surface of the object is easily tilted during the process of crossing the steps, causing the object to fall.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Transfer equipment, used to transport items to be transferred, includes:

[0007] The base extends along the first direction;

[0008] An object mounting platform is connected to the base and is used to mount the object to be transferred.

[0009] A lifting mechanism includes a support wheel and a lifting drive component. The support wheel is used to support itself on the ground or a guide rail and is capable of rolling in a first direction. The lifting drive component has a fixed end and a telescopic end that is telescopic relative to the fixed end. The first of the fixed end and the telescopic end is connected to the base, and the second is connected to the support wheel.

[0010] The lifting mechanism is provided in multiple ways, and the multiple lifting mechanisms are spaced apart along the first direction. When the support wheel of one of the lifting mechanisms is suspended in the air, the support wheels of the other lifting mechanisms can contact the ground or the guide rail.

[0011] As a preferred embodiment of the transfer equipment, the lifting mechanism further includes a connecting rod, the support wheel is disposed on the connecting rod, and a first of the fixed end of the lifting drive component and the telescopic end of the lifting drive component is rotatably connected to the base, while the second is rotatably connected to the connecting rod, and the connecting rod is rotatably connected to the base.

[0012] As a preferred embodiment of the transfer equipment, one of the lifting mechanisms includes two support wheels and two lifting drive components, with the two support wheels symmetrically distributed along the center line of the base.

[0013] As a preferred embodiment of the transfer equipment, the object mounting platform is rotatable relative to the base. The transfer equipment further includes a flipping mechanism, which includes a flipping drive component. The flipping drive component has a fixed end and a telescopic end that is retractable relative to the fixed end. The first of the fixed end and the telescopic end is rotatably connected to the base, and the second is rotatably connected to the object mounting platform. The flipping drive component is capable of driving the object mounting platform to rotate relative to the base.

[0014] As a preferred embodiment of the transfer equipment, the flipping mechanism is provided in two parts, and the two flipping drive components can respectively drive the object mounting platform to rotate in opposite directions relative to the base.

[0015] As a preferred embodiment of the transfer equipment, the object mounting platform is provided with two rotating shafts, both of which are detachably connected to the base. One of the flipping drive components is used to drive the object mounting platform to rotate along one of the rotating shafts, and the other flipping drive component is used to drive the object mounting platform to rotate along the other rotating shaft.

[0016] As a preferred embodiment of the transfer device, the base has a mounting groove, the rotating shaft is rotatably disposed in the mounting groove, and the transfer device further includes a locking structure that prevents the rotating shaft from coming out of the mounting groove.

[0017] As a preferred embodiment of the transfer device, the rotating shaft extends along a second direction, with the first direction perpendicular to the second direction. The locking structure includes an axial locking member, which is slidable relative to the base along the second direction and has an axially locked position and an axially unlocked position. When the axial locking member is in the axially locked position, it is sleeved on the end of the rotating shaft to prevent the rotating shaft from dislodging from the mounting groove. When the axial locking member is in the axially unlocked position, it is separated from the rotating shaft.

[0018] As a preferred embodiment of the transfer device, the rotating shaft extends along a second direction, with the first direction perpendicular to the second direction. The locking structure includes a radial locking member, which is slidable relative to the base along the first direction and has a radially locked position and a radially unlocked position. When the radial locking member is in the radially locked position, it abuts against the outer peripheral wall of the rotating shaft to prevent the rotating shaft from dislodging from the mounting groove. When the radial locking member is in the radially unlocked position, it separates from the rotating shaft.

[0019] As a preferred embodiment of the transfer equipment, each of the lifting mechanisms is equipped with a support wheel drive component, which is used to drive the support wheel to roll along the ground or guide rail.

[0020] The beneficial effects of this invention are:

[0021] This invention provides a transfer device for transporting objects to be transferred. The base of the transfer device extends along a first direction. An object mounting platform is connected to the base and is used to mount the objects to be transferred. The lifting mechanism includes a support wheel and a lifting drive component. The support wheel is used to support itself on the ground or a guide rail and is capable of rolling along the first direction. The lifting drive component has a fixed end and a telescopic end that can extend and retract relative to the fixed end. The first of the fixed end and the telescopic end is connected to the base, and the second is connected to the support wheel, thereby changing the distance between the base and the support wheel. Multiple lifting mechanisms are arranged at intervals along a first direction. When the support wheel of one lifting mechanism is suspended in the air, the support wheels of the remaining lifting mechanisms can contact the ground or guide rails. When it is necessary to cross steps or travel to bumpy surfaces, the lifting drive of one lifting mechanism can be retracted, raising the support wheel relative to the ground and suspending it in the air. At this time, the support wheels of the remaining lifting mechanisms can contact the ground or guide rails without affecting the angle of the base and the object mounting platform, ensuring that the object to be transferred remains stably mounted on the object mounting platform. As the transfer equipment continues to travel, the suspended support wheel is re-supported on the upper surface of the step or the bumpy surface, enabling the transfer equipment to travel when encountering steps or bumpy surfaces. Furthermore, the entire process requires no manual pushing, resulting in labor-saving efficiency. Attached Figure Description

[0038] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0039] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0040] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0041] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0042] Currently, the transfer of objects on drilling platforms typically uses non-powered flatbed carts, pushed manually. When objects need to cross steps, manual assistance is required from lifting equipment to raise and lower both the objects and the transport equipment, a time-consuming and labor-intensive process. Existing technology offers a transfer vehicle with a front support and a height-adjustable rear support fixedly connected to the bottom of the vehicle. The height of the rear support is adjustable; when encountering steps, the height of the rear support is adjusted, and workers push the vehicle by hand. As it crosses the steps, the wheels of the rear support act as a fulcrum, lifting the small rollers at the front so they contact the upper surface of the step. However, this solution still requires manual operation of the transfer vehicle to cross steps. Furthermore, the process of crossing steps can easily cause the mounting surface of the object to tilt, leading to the object falling.

[0043] To address the aforementioned issues, this embodiment provides a transfer device to solve the problem in the prior art where manual operation of a transfer vehicle is required to cross steps. Furthermore, the process of crossing steps can easily cause the mounting surface of the object to tilt, leading to the object falling off. This device can be used in the field of object transfer technology.

[0044] Reference Figures 1-5 The transfer equipment is used to transport the object 100 to be transferred, and includes a base 1, an object mounting platform 2, and a lifting mechanism 3. The base 1 extends along a first direction; the object mounting platform 2 is connected to the base 1 and is used to mount the object 100 to be transferred; the lifting mechanism 3 includes a support wheel 31 and a lifting drive component 32. The support wheel 31 is used to support itself on the ground or a guide rail 200 and is capable of rolling along the first direction. The lifting drive component 32 has a fixed end 321 and a telescopic end 322 that can extend and retract relative to the fixed end 321. A first portion of the fixed end 321 and the telescopic end 322 is connected to the base 1, and a second portion is connected to the support wheel 31, thereby changing the distance between the base 1 and the support wheel 31. This embodiment exemplarily provides a scheme in which the fixed end 321 of the lifting drive component is connected to the base 1, and the telescopic end 322 of the lifting drive component is connected to the support wheel 31.

[0045] Continue to refer to Figures 1-5Multiple lifting mechanisms 3 are provided, spaced apart along a first direction. When the support wheel 31 of one lifting mechanism 3 is suspended, the support wheels 31 of the remaining lifting mechanisms 3 can contact the ground or guide rail 200. When it is necessary to cross steps or travel to a bumpy surface, the lifting drive component 32 of one lifting mechanism 3 can be retracted to raise and suspend the support wheel 31 relative to the ground. At this time, the support wheels 31 of the remaining lifting mechanisms 3 can contact the ground or guide rail 200, without affecting the angle of the base 1 and the object mounting platform 2, so that the object 100 to be transferred can still be stably installed on the object mounting platform 2. As the transfer equipment continues to move, the suspended support wheel 31 is re-supported on the upper surface of the step or the bump of the bumpy surface, so that the transfer equipment can travel when encountering steps or bumpy surfaces. In addition, the whole process does not require manual pushing, which has the effect of saving effort.

[0046] The following is for reference Figures 2-4 This describes the status of each lifting mechanism 3 when the transfer equipment needs to cross steps. For example... Figure 2 As shown, the transfer equipment travels on the guide rail 200, at which time all the lifting drive components 32 are in a retracted state. When encountering a step, the lifting drive component 32 of the foremost lifting mechanism 3 remains stationary, while the remaining lifting drive components 32 begin to extend, that is, the telescopic end 322 of the lifting drive component extends relative to the fixed end 321 of the lifting drive component, as shown. Figure 3 As shown, at this time, the base 1 and the object mounting platform 2 are raised as a whole, and the angles of the base 1 and the object mounting platform 2 remain unchanged, thus preventing any change in the installation angle of the object 100 to be transferred, allowing the object 100 to be transferred to remain stably mounted on the object mounting platform 2. Subsequently, the transfer equipment continues to move forward, causing the foremost lifting mechanism 3 to move to the guide rail 200 above the step. At this time, the lifting drive 32 of the lifting mechanism 3 can be controlled to extend appropriately, so that the support wheel 31 of the lifting mechanism 3 contacts the guide rail 200 above the step. Simultaneously, the support wheels 31 of the other lifting mechanisms 3 are in contact with the guide rail 200 below the step, without any suspension. This completes the step crossing of one of the lifting mechanisms 3's support wheels 31. Then, the lifting drive 32 of the second lifting mechanism 3 is retracted to suspend the support wheel 31, and the above operation is repeated, allowing the support wheel 31 of the second lifting mechanism 3 to contact the guide rail 200 above the step. By repeating this operation multiple times, all lifting mechanisms 3 can cross the steps, thus enabling the transfer equipment to complete the step crossing.

[0047] Continue to refer to Figures 1-5The problem with the above structure is that if both ends of the lifting drive component 32 are directly connected to the base 1 or the support wheel 31 without any other connecting structure, the connection between the two ends of the lifting drive component 32 will be unstable. To address this, the lifting mechanism 3 also includes a connecting rod 33. The support wheel 31 is mounted on the connecting rod 33. The first of the two ends of the lifting drive component—the fixed end 321 and the telescopic end 322—is rotatably connected to the base 1, and the second is rotatably connected to the connecting rod 33. The connecting rod 33 is rotatably connected to the base 1, meaning the first end is connected to the support wheel 31 via the connecting rod 33.

[0048] Continue to refer to Figures 1-5 One of the lifting mechanisms 3 includes two support wheels 31 and two lifting drive components 32. The two support wheels 31 are symmetrically distributed along the center line of the base 1 so that the multiple lifting mechanisms 3 of the transfer equipment are evenly supported on the ground or guide rail 200. During the process of crossing the steps, the two lifting drive components 32 of the lifting mechanism 3 simultaneously complete the corresponding actions.

[0049] Continue to refer to Figures 1-5 The object mounting platform 2 can rotate relative to the base 1. The transfer equipment also includes a flipping mechanism 4, which includes a flipping drive 41. The flipping drive 41 has a fixed end 411 and a telescopic end 412 that can extend and retract relative to the fixed end 411. The first of the fixed end 411 and the telescopic end 412 is rotatably connected to the base 1, and the second is rotatably connected to the object mounting platform 2. The flipping drive 41 can drive the object mounting platform 2 to rotate relative to the base 1, thereby changing the angle of the object mounting platform 2, which facilitates loading and unloading of the object 100 to be transferred, or adjusting the installation angle of the object 100 to be transferred.

[0050] Continue to refer to Figures 1-5 There are two flipping mechanisms 4. The two flipping drive units 41 can drive the object mounting platform 2 to rotate in opposite directions relative to the base 1, so that the object mounting platform 2 can rotate in two directions, thereby increasing the angle adjustment range of the object mounting platform 2.

[0051] Continue to refer to Figures 1-5 The object mounting platform 2 is equipped with two rotating shafts 21, both of which are detachably connected to the base 1. One rotating drive 41 drives the object mounting platform 2 to rotate along one of the rotating shafts 21, and the other rotating drive 41 drives the object mounting platform 2 to rotate along the other rotating shaft 21. The detachable connection between the rotating shafts 21 and the base 1 facilitates the assembly of the object mounting platform 2. In addition, the two rotating drive 41 can also drive the object mounting platform 2 to move simultaneously, thereby lifting the object mounting platform 2 relative to the base 1.

[0052] Reference Figures 1-7 The base 1 has a mounting groove 11, and the rotating shaft 21 is rotatably mounted in the mounting groove 11. The transfer device also includes a locking structure 5, which can prevent the rotating shaft 21 from coming out of the mounting groove 11. Thus, when the object mounting platform 2 rotates along the rotating shaft 21, the rotating shaft 21 can be prevented from coming out of the mounting groove 11, so that the object mounting platform 2 can rotate stably relative to the base 1.

[0053] Continue to refer to Figures 1-7 The rotating shaft 21 extends along the second direction, and the first direction is perpendicular to the second direction. The locking structure 5 includes an axial locking member 51. The axial locking member 51 can slide relative to the base 1 along the second direction and has an axial locking position and an axial unlocking position. When the axial locking member 51 is in the axial locking position, the axial locking member 51 is sleeved on the end of the rotating shaft 21, thereby limiting the end of the rotating shaft 21 to prevent the rotating shaft 21 from coming out of the mounting groove 11. When the axial locking member 51 is in the axial unlocking position, the axial locking member 51 is separated from the rotating shaft 21, thereby realizing the unlocking between the object mounting platform 2 and the base 1.

[0054] Continue to refer to Figures 1-7 The locking structure 5 also includes a radial locking member 52, which can slide relative to the base 1 in a first direction and has a radial locking position and a radial unlocking position. When the radial locking member 52 is in the radial locking position, the radial locking member 52 abuts against the outer peripheral wall of the rotating shaft 21. Specifically, the rotating shaft 21 can enter and exit the mounting groove 11 through the opening of the mounting groove 11. The radial locking member 52 abuts against the rotating shaft 21 along the movement direction of the rotating shaft 21 and is located on the side of the rotating shaft 21 near the opening to prevent the rotating shaft 21 from coming out of the mounting groove 11. When the radial locking member 52 is in the radial unlocking position, the radial locking member 52 separates from the rotating shaft 21, thereby realizing the unlocking between the object mounting platform 2 and the base 1.

[0055] Continue to refer to Figures 1-7 Each lifting mechanism 3 has a support wheel drive component 311 installed on its support wheel 31. The support wheel drive component 311 is used to drive the support wheel 31 to roll along the ground or guide rail 200, thereby providing driving force to the support wheel 31 of each lifting mechanism 3 individually, which facilitates the control of the travel and steering of the transfer equipment.

[0056] Optionally, the transfer equipment also includes a power supply assembly 6 disposed on the base 1. The power supply assembly 6 includes a power supply and a controller. The controller is electrically connected to the power supply and is communicatively connected to the support wheel drive 311, the lifting drive 32, the tilting drive 41, the axial locking member 51, and the radial locking member 52 to control the above structures to achieve the corresponding actions.

[0057] Optionally, the lifting drive 32, the tilting drive 41, the axial locking component 51, and the radial locking component 52 are all hydraulically controlled, and the support wheel drive 311 is a hydraulic motor. The transfer equipment also includes a hydraulic control system 7 installed on the base 1, which is used to provide oil to the above structure.

[0058] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
