Description

Technical Field

[0001] The present invention is applied to the technical field of steel plate transportation, and more specifically, relates to a transport trolley and system with a steering function for transferring steel plates in a steel plate warehouse. Background Art

[0002] Hot-rolled medium and heavy plates, after rolling off the production line, are typically rotated 90 degrees when transported to the plasma cutting area via a transport trolley. Traditionally, this rotation has been achieved using a rotating spreader mounted on a crane, requiring the trolley to operate within the crane's reach. This rotation becomes ineffective when the plasma cutting machine is positioned adjacent to a plant column or outside the crane's reach. Therefore, a transport trolley with a steering function is required to ensure accurate rotation of the plate to be cut by the plasma cutter. Summary of the Invention

[0018] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0019] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0020] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0021] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediary, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0022] Example 1

[0023] From above Figure 1-3 It can be seen that the transport trolley with steering function designed in this embodiment includes a moving body structure 1, a rotating body structure 2, a track 3, a traveling transmission device 4, a rotating transmission device 5, a power supply device 6, a latch fixing device 7, an auxiliary rotation and support structure 8, and a rotating body locking device 9.

[0024] The mobile body structure 1 and the rotating body structure 2 form a composite body structure. A motor and a reduction mechanism are provided at the center of the bottom of the mobile body. The drive shaft of the reduction mechanism extends upward from the mobile body and connects to the center of the rotating body to drive the rotating body to rotate relative to the mobile body.

[0025] A drive motor is also provided at the bottom of the mobile body; the drive motor is connected to a set of running wheels of the mobile body for driving the mobile body to move along the track;

[0026] The power supply device 6 is an existing technology (for example, the busbar power supply device of Chinese patent application No. 200820039556.1), which draws power through a busbar. The power supply device 6 is arranged on one side of the mobile body and is used to make a sliding contact connection with the power supply wires on one side or both sides of the track to provide power for the mobile body structure 1 and the rotating body structure 2.

[0027] The latch fixing device 7 is provided on the mobile body and can be an electric latch cylinder; a socket or slot adapted to the latch fixing device is provided on the lower surface of the rotating body; before joining the materials, the rotating body and the mobile body are locked by the latch fixing device 7.

[0028] The auxiliary rotation and support structure 8 is arranged under the rotating body and is adapted to the mobile body and the rotating platform; it can be a rotating roller, a roller, etc.

[0029] The rotating vehicle body locking device 9 can be a supporting device mainly based on an electric, pneumatic or hydraulic latch cylinder.

[0030] After the composite car body receives the steel plate stack, it is driven by the traveling transmission device 4 to transport the steel plate stack to the transfer position. After the transport trolley stops, the brake of the traveling transmission device 4 is engaged to ensure that the position of the transport trolley is locked. Then, the latch fixing device 7 is opened, and the rotating transmission device 5 drives the rotating car body structure 2 to rotate. At the same time, under the action of the auxiliary rotation and support structure 8, the rotating car body structure 2 transfers the steel plate stack to the unloading position. After the rotating car body structure 2 completes the movement, the rotating transmission device 5 engages the brake to ensure that the position of the rotating trolley is locked. The rotating car body locking device 9 is installed on the rotating platform at the end of the rotating track. At this time, the latch cylinder of the rotating car body locking device 9 extends to fix the position of the rotating car body structure 2, and the steel plate stack can be lifted away.

[0031] After unloading is complete, the latch cylinder of the rotating body locking device 9 retracts, the brake of the rotating transmission device 5 is released, and the rotating body structure 2 is reset by the rotating transmission device 5. The latch fixing device 7 locks the rotating body. The brake of the travel transmission device 4 is released, and the travel transmission device 4 drives the transport trolley back to the steel plate stack to receive the material. The brake of the travel transmission device 4 engages to ensure that the transport trolley is accurately positioned at the receiving position. The above-mentioned receiving position, transfer position, and unloading position are all precisely controlled by the position detection device to ensure the operational accuracy of the transport trolley.

[0032] Compared to previous mobile transport devices, the steering transport trolley of the present invention boasts a novel structure, comprehensive functionality, strong system integration, and low manufacturing costs. The invention's ingenuity lies in its design of a combined mobile and rotating vehicle body, which replaces the rotating spreader and greatly facilitates the transfer and transportation of stacks of panels. The motors of both the travel and rotating transmissions are equipped with brakes and variable frequency capabilities, ensuring precise starting and stopping, as well as operational stability.

Various modifications may be made within the scope of knowledge of those skilled in the art without departing from the spirit of the present invention. Many other changes and modifications that do not depart from the spirit and scope of the present invention should be considered within the scope of protection of the present invention.

[0034] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0035] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto.
