Description

Technical Field

[0001] The invention relates to a special device for realizing automatic pick-up, placement and maintenance of shuttle vehicles in a multi-pass system, belonging to the field of logistics and warehousing. Background Art

[0002] Automation and intelligent control technologies are rapidly developing in the logistics and warehousing sectors. With the increasing demand for industrial and commercial land and labor costs, intensive transit warehouses offer higher operational efficiency by fully utilizing space and reducing labor requirements. Four-way shuttles, commonly used in automated high-bay warehouses, can switch directions along intersecting tracks, traveling longitudinally or transversely, to reach any designated warehouse location based on order requirements, enabling intensive storage and transportation.

[0003] In existing multi-pass systems, when a shuttle car needs maintenance, the operator manually lifts it off the shelf track and uses a layer-changing elevator or forklift to transfer the shuttle car to the maintenance station; similarly, after the maintenance is completed, the operator still needs to manually return the shuttle car to the track before normal operation can be restored. Since existing multi-pass systems do not have dedicated maintenance elevators, the maintenance of a few shuttle cars will inevitably affect the normal use of other shuttle cars, and occupy other equipment resources such as layer-changing elevators and forklifts, reducing the overall operating efficiency of the multi-pass system. On the other hand, the use of forklifts to pick up and transfer shuttle cars is often limited by the height of the forklift and the conditions of the multi-pass system track structure. The forklift is often unable to reach the site, which increases the labor load and easily causes the risk of further damage to the shuttle car during the transfer process.

[0004] In view of this, this patent application is filed. Summary of the Invention

[0005] The shuttle car maintenance hoist and method described in the present invention are intended to solve the problems existing in the above-mentioned prior art and propose a special maintenance hoisting equipment. When the shuttle car is repaired, it does not affect the operation of other vehicles, and the multi-pass system can still operate normally. At the same time, it is convenient for the shuttle car to be transferred without affecting the efficiency of entering and leaving the warehouse, thereby realizing two maintenance operations of shuttle car transfer and on-site maintenance of shelves, achieving the design purpose of significantly reducing the workload of operators and improving maintenance quality and efficiency.

[0006] To achieve the above-mentioned design purpose, the shuttle maintenance hoist includes a lifting frame, which is connected to the shelves of the multi-through system through an array of crossbeams; a remote-controlled lifting hoist is provided on the top of the lifting frame, and a lifting assembly for carrying the tool vehicle is slidably connected along the side of the lifting frame, and a group or array of transition guide rails for the shuttle vehicle to travel and enter and exit the tool vehicle are laterally connected to the side of the lifting frame; the lifting assembly has a lifting assembly frame, and an array of guide wheel assemblies are provided on both sides of the lifting assembly frame, and the guide wheel assemblies are clamped to the lifting frame from both sides to the middle, and a group of support rails for supporting the tool vehicle to enter and exit are respectively provided on both sides of the bottom of the lifting assembly frame, and pin shaft sockets for connecting the tool vehicle are respectively provided on both sides of the lifting assembly frame.

[0007] Furthermore, the tooling vehicle includes a vehicle body, a set of guide rails are symmetrically arranged on both sides of the vehicle body, and a trolley pin shaft is respectively arranged on both sides of the vehicle body.

[0008] Furthermore, the remote-controlled hoist is suspended on the crossbeam of the top layer of the lifting frame through the fixed pull ring on its top, and the pull hook at the bottom of the remote-controlled hoist is used to hook the top of the lifting component to lift it vertically.

[0009] Furthermore, the transition guide rail has a C-shaped through groove with an opening facing inward, and a shuttle rear block and a shuttle front block are respectively provided on each set of guide rails to limit the displacement of the shuttle on the tooling vehicle.

[0010] Furthermore, the shelf block has transversely arranged grooves, and the side of the shelf block is fixedly connected to the lifting frame through studs; one end of the transition guide rail is inserted into the groove on the shelf block, and the other end is overlapped on the front beam of the work vehicle.

[0011] Based on the structural design of the above shuttle maintenance hoist, this application also proposes the following method of using the shuttle maintenance hoist:

[0012] A lifting frame of a shuttle maintenance lift is provided on one side of the multi-pass system shelf where the shuttle is running;

[0013] Connect the lifting frame to each layer of the multi-through system rack through the array beams;

[0014] A remote-controlled hoist is provided on the top of the lifting frame, and a lifting assembly carrying a tool vehicle is slidably connected along the side of the lifting frame. A group or array of transition guide rails for the shuttle vehicle to travel in and out of the tool vehicle is laterally connected to the side of the lifting frame;

[0015] When the shuttle needs to be moved from the rack of the multi-pass system for maintenance, perform the following steps:

[0016] 1) Place the lifting component on the ground through the remote control hoist;

[0017] 2) Push the tooling vehicle into the lifting assembly;

[0018] 3) Use the remote-controlled hoist to lift the tooling vehicle to the side of the shelf track at the corresponding height of the shuttle car, and connect the shelf rail with the tooling vehicle through the transition rail;

[0019] 4) Push the shuttle car into the tooling car, and then use the remote-controlled hoist to lower the lifting assembly to the ground, so that the tooling car and the shuttle car can be pushed to the designated maintenance station for maintenance;

[0020] 5) After the inspection is completed, push the shuttle car back into the tooling car, lift the tooling car and the shuttle car together with the remote-controlled hoist, and push the shuttle car from the tooling car back to the shelf track through the transition guide rail.

[0021] Furthermore, the remote control hoist is suspended on the crossbeam of the top layer of the lifting frame through the fixed pull ring on its top, and the pull hook at the bottom of the remote control hoist hooks the top of the lifting component to lift it vertically.

[0022] Furthermore, the transition guide rail has a C-shaped through groove with an opening facing inward, and the running wheels of the shuttle can slide back and forth on the inner bottom surface of the C-shaped through groove.

[0023] Furthermore, during the vertical lifting process of the lifting assembly, guide wheel assemblies are provided on both sides of the lifting assembly frame, which are clamped on the lifting machine frame from both sides to the middle to provide guidance and support for the lifting assembly frame during operation.

[0024] Furthermore, a set of guide rails are symmetrically arranged on both sides of the tooling vehicle body. The guide rails have the same structure as the transition guide rails. The guide rails are docked with the transition guide rails to push the shuttle vehicle to be repaired into the tooling vehicle, and to push the shuttle vehicle after repair out of the tooling vehicle.

[0025] In summary, the shuttle vehicle maintenance hoist and method described in this application have the following advantages:

[0026] 1. This application proposes a special maintenance, lifting and transfer equipment. The lifting frame is the same height as and matches the shelves of the existing multi-pass system, which not only facilitates the lifting, transfer and re-shelving of shuttle vehicles, but also enables on-site maintenance operations of shuttle vehicles on all levels, making the maintenance process more efficient.

[0027] 2. The maintenance elevator proposed in this application facilitates the automated control and transfer of faulty shuttle vehicles to the maintenance station. The shuttle vehicles after repair do not need manual assistance to return to the track of the designated shelf layer, which significantly reduces the workload of on-site maintenance personnel. The quality of maintenance work is high, and the shuttle vehicles will not suffer secondary damage during the transfer process.

[0028] 3. The maintenance elevator proposed in this application does not occupy the resources of the layer-changing elevator, will not affect the working rhythm of the overall multi-through system, and correspondingly improves the warehousing and outbound operation efficiency of the multi-space system.

A group or array of transition guide rails 5 for a shuttle vehicle to travel in and out of the tooling vehicle is laterally connected to the side of the lifting frame 2;

[0039] The hoist frame 2 constitutes the overall installation and fixing frame of the hoist, and provides a guide for the vertical lifting of the hoist assembly 6; it is connected to the shelf of the multi-through system through the crossbeam 3, which can correspondingly improve the overall stability of the maintenance hoist;

[0040] The remote-controlled lifting hoist 1 is suspended on the crossbeam 3 of the top layer of the lifting frame 2 by the fixed pull ring 17 on its top. The hook 18 at the bottom of the remote-controlled lifting hoist 1 is used to hook the top of the lifting component 6 and lift it vertically to realize the lifting operation of the tooling vehicle carrying the shuttle vehicle that needs to be inspected or repaired.

[0041] Furthermore, the transition guide rail 5 has a C-shaped through groove 14 with an opening facing inward, and the running wheels of the shuttle can slide back and forth on the inner bottom surface of the C-shaped through groove 14;

[0042] The lifting assembly 6 has a lifting assembly frame 61, and an array of guide wheel assemblies 64 are arranged on both sides of the lifting assembly frame 61. The guide wheel assemblies 64 are clamped on the lifting machine frame 2 from both sides to the middle to achieve guidance and protection of the lifting assembly frame 61 when it is lifted and lowered vertically; a lifting assembly frame 61 is provided with a lifting ring 63 for suspending the hook 18 at the bottom of the remote control hoist 1 at the top, and a group of support rails 63 for supporting the tooling vehicle 4 to move in and out are respectively arranged on both sides of the bottom of the lifting assembly frame 61, and a pin shaft socket 65 for connecting the tooling 4 is respectively provided on both sides of the lifting assembly frame 61.

[0043] The tooling vehicle 4 includes a vehicle body formed by assembling a longitudinal beam 11, a front beam 13 and a bottom plate.

The guide rails 9 are docked with the transition guide rails 5 to push the shuttle vehicle to be inspected into the tooling vehicle 4, and to push the shuttle vehicle after inspection out of the tooling vehicle 4.

[0064] In addition, trolley pins 10 are provided on both sides of the body of the tooling vehicle 4 to securely connect the tooling vehicle 4 to the lifting assembly 6 to prevent the tooling vehicle 4 from tilting or moving during the lifting process.

[0065] Furthermore, a shuttle rear block 8 and a shuttle front block 12 are respectively provided on each set of guide rails 9 to limit the displacement of the shuttle on the tooling vehicle, thereby preventing the shuttle from tilting or moving during the lifting of the tooling vehicle 4 along with the lifting assembly 6 .
