Description

Technical Field

[0001] The utility model relates to the technical field of four-way shuttle vehicles, in particular to a movable blocking device and a hoist for a four-way shuttle vehicle. Background Art

[0002] With the rapid development of the logistics industry, the automated warehouse system has become increasingly important because it can greatly improve space utilization, reduce labor costs and improve logistics efficiency. In this system, four-way shuttles and elevators play a vital role. They are key equipment for efficient cargo storage and retrieval.

[0003] In high-rise warehouses, each shelf is directly connected to the in-and-out elevator, which allows for quick exchange of goods on each shelf. The elevator uses internal positioning sensors to accurately reach the target shelf level and can be raised and lowered to the same height as the shelf, thus achieving barrier-free goods exchange. This process not only improves operational efficiency, but also reduces possible errors and damage during cargo handling.

[0004] In actual use, the automation system may encounter problems such as signal loss or layer positioning errors. These problems may be caused by a variety of factors, such as unstable network communication, software program vulnerabilities, sensor failures, etc. Once this happens, the lifting platform of the elevator may not be able to accurately reach the predetermined target layer. If the four-way shuttle continues to perform the layer change operation according to the original task at this time without properly docking with the elevator, a serious safety accident may occur in which the goods or the shuttle rush out of the shelf and fall. This risk may not only cause property damage, but also endanger personnel safety.

[0005] In view of this, although conventional elevator operations rely on photoelectric sensors and software control to achieve precise control of the lifting level, as well as the delivery of goods on each shelf and the travel of the four-way shuttle, these systems cannot 100% eliminate the possibility of errors. Therefore, the existing technology urgently needs a safer and more reliable solution to prevent accidents caused by signal or positioning problems. Utility Model Content

[0040] The utility model provides the following description with reference to the accompanying drawings to help fully understand the various embodiments of the utility model as defined by the claims and their equivalents. The description includes various specific details to help understanding, but these details should be regarded as exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the utility model.

[0041] In the description of the present invention, descriptions of orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0042] It will be understood that when one element (eg, a first element) is “connected” to another element (eg, a second element), the element may be directly connected to the other element or an intervening element (eg, a third element) may be present between the element and the other element.

[0043] The embodiment of the utility model provides a movable blocking device for a four-way shuttle vehicle, comprising:

[0044] A fixed base 1, used for fixing the movable blocking device body;

[0045] The blocking mechanism 2 is used to block the four-way shuttle vehicle. The blocking mechanism 2 is rotatably connected to the fixed base 1. The blocking mechanism 2 has a blocking state and an unblocking state.

[0046] A reset mechanism 4, one end of which is connected to the fixed base 1, and the other end of which is connected to the blocking mechanism 2, for driving the blocking mechanism 2 to perform rotational reset;

[0047] The pushing mechanism 3, when the pushing mechanism 3 reaches the position of the blocking mechanism 2, the pushing mechanism 3 pushes the blocking mechanism 2 to rotate and release the blocking state; when the pushing mechanism 3 leaves the position of the blocking mechanism 2, the blocking mechanism 2 rotates and resets to form the blocking state.

[0048] The blocking mechanism 2 is installed at the entrance through the fixed base 1, and is initially in a blocking state to block the four-way shuttle. When the pushing mechanism 3 reaches the position of the blocking mechanism 2, the pushing mechanism 3 causes the blocking mechanism 2 to rotate to release the blocking state. When the pushing mechanism 3 leaves the position of the blocking mechanism 2, the blocking mechanism 2 will rotate and reset due to the lack of the push of the pushing mechanism 3 and under the action of the resetting mechanism 4.

[0049] The fixed base 1 serves as a supporting base for the entire blocking device, and the stability of the fixed base 1 is crucial to the entire system.

[0050] The blocking mechanism 2 is the part that directly contacts the shuttle, and its design needs to be able to withstand the impact force of the shuttle, and can flexibly rotate to allow or prevent the shuttle from moving. The blocking mechanism 2 usually includes one or more blocking surfaces, which can rotate freely on the rotating shaft 101.

[0051] The function of the reset mechanism 4 is to restore the blocking mechanism 2 to its original blocking position after the pushing mechanism 3 leaves.

[0052] The pushing mechanism 3 is a component connected to the elevator, which is responsible for pushing the blocking mechanism 2 to rotate and release the blocking state. The design of the pushing mechanism 3 needs to be precise to ensure that the shuttle car is released in time when it reaches the correct level.

[0053] In some embodiments, the fixed base 1 further includes a limit block 102 for limiting the rotation position of the blocking mechanism 2 .

[0054] In some embodiments, the blocking mechanism 2 comprises:

[0055] A blocking element 201, wherein the blocking element 201 is provided with a protrusion 202 that protrudes into the moving path of the four-way shuttle and blocks the movement thereof;

[0056] The transmission element 203 is disposed on the blocking element 201 , and the blocking element 201 is driven to rotate by changing the position of the transmission element 203 .

[0057] The blocking element 201 is designed to directly contact the four-way shuttle and prevent it from moving. The protrusion 202 provided on the blocking element 201 is a component that actually performs the blocking function. When the protrusion 202 is in the moving path of the four-way shuttle, the movement of the shuttle can be effectively blocked.

[0058] The function of the transmission element 203 is to drive the blocking element 201 to rotate by changing its position, thereby realizing the switching between the blocking state and the released state. The transmission element 203 can be a gear, a wheel, a lever or any other movable mechanical part, and its design needs to allow effective interaction with the pushing mechanism 3.

[0059] Furthermore, a rotating shaft 101 is provided on the fixed base 1, the blocking element 201 is a blocking plate vertically sleeved on the rotating shaft 101, the protrusion 202 is a protrusion on the blocking plate, and the transmission element 203 is a swing wheel.

[0060] The blocking element 201 is composed of a blocking plate, which is vertically sleeved on the rotating shaft 101. This design allows the blocking plate to rotate freely around the rotating shaft 101, realizing dynamic switching between blocking and releasing. The protrusion 202 is one or more protrusions, which will protrude onto the moving path of the four-way shuttle when the blocking plate rotates to a specific position, directly contact the shuttle, and thus play a blocking role. The transmission element 203 is composed of a swing wheel, which is arranged at the bottom of the blocking plate. The design of the swing wheel enables it to interact with the pushing mechanism 3 on the elevator, and realize the rotation of the blocking plate through physical pushing.

[0061] Furthermore, the swing wheel includes a fixed shaft 204 and a rotating wheel 205 , and the rotating wheel 205 is rotatably sleeved on the fixed shaft 204 .

[0062] The swing wheel design includes a fixed shaft 204, which is fixed to the bottom of the blocking plate. The fixed shaft 204 provides a stable central support for the swing wheel, ensuring that it maintains an accurate center position when rotating. Coordinated with the fixed shaft 204 is a rotating wheel 205, which is designed to rotate around the fixed shaft 204. The rotating wheel 205 is the component that actually contacts the driving mechanism 3 and responds to its driving force. The rotating wheel 205 can be rotatably sleeved on the fixed shaft 204, which means that the rotating wheel 205 can rotate freely on the fixed shaft 204, without axial movement, only circumferential rotation. The setting of the rotating wheel 205 can effectively reduce the friction when the driving mechanism 3 and the blocking mechanism 2 contact.

[0063] In some embodiments, the pushing mechanism 3 includes:

[0064] A guide element 301, wherein the guide element 301 is provided with a first guide end 302 capable of driving the blocking mechanism 2 to rotate;

[0065] The guide element fixing part 304 has one end fixed on the elevator and the other end fixed on the guide element 301 .

[0066] The guide element 301 has two guide ends, namely a first guide end 302 and a second guide end 303. These guide ends are designed to interact with a specific part of the blocking mechanism 2 to promote its rotation.

[0067] The first guide end 302 is a part of the guide element 301, which is designed to contact the transmission element 203 of the blocking mechanism 2. When the elevator moves to the position of the blocking mechanism 2, the first guide end 302 pushes the swing wheel, causing the blocking mechanism 2 to start rotating.

[0068] The second guide end 303 is another part of the guide element 301 , and is used to continue to guide or stabilize the rotation of the blocking mechanism 2 after the pushing process is completed, or to serve as an auxiliary part for resetting the blocking mechanism 2 .

[0069] Further, the guide element 301 is a guide plate, the first guide end 302 is a first guide slope on the guide plate, and the second guide end 303 is a second guide slope on the guide plate.

[0070] As a part of the pushing mechanism 3 , the guide plate is a flat plate-shaped element, which plays a guiding and positioning role in the pushing mechanism 3 .

[0071] The guide plate is specially designed with an inclined surface, which is called the first guiding inclined surface. This inclined surface interacts with the transmission element 203 of the blocking mechanism 2 to promote the blocking mechanism 2 to rotate to the unblocking state.

[0072] In addition to the first guiding slope, the guide plate is also provided with a second guiding slope, which is used to continue to guide the blocking mechanism 2 to rotate to a certain position or to assist in the resetting process.

[0073] Furthermore, the guide plate further includes a vertical surface 305 vertically tangent to the transmission element 203 .

[0074] The presence of the vertical surface 305 means that the guide plate has room to move beyond the strictly necessary range, and can work normally even if its position is not completely accurate. The vertical surface 305 allows the guide plate to move within a certain error range without affecting the function of the blocking mechanism 2, thereby improving the fault tolerance of the system.

[0075] Furthermore, the top of the guide plate is a horizontal structure.

[0076] The horizontal top structure helps reduce the likelihood of the shuttle coming into contact with the guide plate, thereby reducing the risk of damage due to physical impact.

[0077] In some embodiments, the reset mechanism 4 includes:

[0078] A spring fixing seat 401, the spring fixing seat 401 is fixed on the fixing base 1;

[0079] A spring fixing support 402, wherein the spring fixing support 402 is fixed on the spring fixing seat 401;

[0080] A tension spring 403 , one end of which is fixed on the spring fixing support 402 , and the other end of which is fixed on the blocking mechanism 2 .

[0081] An embodiment of the utility model provides an elevator, including an elevator body 5, the elevator body 5 includes an elevator frame 501, a lifting mechanism 503 and a movable blocking device for a four-way shuttle as in any of the above embodiments, each layer of the elevator frame 501 is provided with a side beam 502 facing the four-way shuttle, the lifting mechanism 503 is installed with a pushing mechanism 3, and the side beam 502 is installed with a blocking mechanism 2.
