Abstract
Description
Technical Field
[0001] This utility model relates to the field of shuttle vehicle technology, and in particular to a novel special rack for shuttle vehicles. Background Technology
[0002] Shuttles in warehousing and logistics equipment mainly come in two forms: shuttle-type inbound / outbound systems and shuttle-type storage systems. These are trolleys that run on fixed tracks in a reciprocating or looping manner, transporting goods to designated locations or connecting equipment. They are equipped with intelligent sensing systems that can automatically memorize the origin position and automatic deceleration systems.
[0003] In existing technologies, traditional shelving systems use side skirts on both sides of the wheels to engage with the sides of the travel track, similar to the relationship between train wheels and train tracks. Figure 1 and Figure 2 The arrow positions are designed to ensure the vehicle doesn't deviate from its track during operation, necessitating a dedicated track for each level of the shelving. Therefore, traditional shelving typically has a track laid 30-40 centimeters above the ground for the vehicle to travel on. This is the standard practice in current technologies.
[0004] Currently, in the existing racking system, there are uneven tracks between the main aisle rails and the sub-aisle rails, and there are also track breaks at the intersections of the sub-aisle rails and the main aisle rails. Figure 2 As shown, 'a' is the sub-channel track, 'b' is the main channel track, and the break is the gap between the two tracks. This gap is designed to allow the side-wheeled wheels of a traditional four-way shuttle to pass freely. Figure 3 As shown, the distance between the reference plane 1 of the traditional shelving bracket and the reference plane 2 of the main aisle rail is 50mm. Figure 4 The arrow represents the traditional corbel structure.
[0005] When the four-way shuttle passes through at high speed, it will generate a lot of noise and strong vibrations, which will cause significant damage to the vehicle body and the racks, reducing their service life. In addition, the wheels with skirts may derail when the vehicle is traveling at high speed, posing a certain safety hazard. Utility Model Content
[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a new type of special rack for shuttle cars, which changes the high and low rails of the rack to a flat rail structure and sets a guide mechanism on the flat rail structure, so that the shuttle car can move stably on the rack rails, improving the safety and service life of the vehicle.
[0007] The above-mentioned utility model objective is achieved through the following technical solution:
[0008] A novel shuttle-specific rack includes a rack body with several layers of flat rails on the rack body. The flat rails include a main channel rail and several sub-channel rails vertically arranged on one side of the main channel rail.
[0009] As a further technical solution of this utility model: the top surface of the main channel track and the top surfaces of several sub-channel tracks are located on the same horizontal plane.
[0010] As a further technical solution of this utility model: main channel guide components are symmetrically arranged on both sides of the main channel track.
[0011] As a further technical solution of this utility model: Sub-channel guide plates are symmetrically arranged on both sides of the sub-channel track. When the new shuttle car travels on the sub-channel track, the guide wheels on both sides of the new shuttle car contact the inner wall surfaces of the sub-channel guide plates on both sides of the sub-channel track.
[0012] As a further technical solution of this utility model: the wheels of the novel shuttle moving on the flat track are flat wheels.
[0013] As a further technical solution of this utility model: the main aisle track includes two parallel main track rods, which are detachably fixed to the shelf body; the sub-aisle track includes two parallel sub-track rods, which are detachably fixed to the shelf body; and several sub-track rods are perpendicular to the main track rods.
[0014] As a further technical solution of this utility model: the main channel guide assembly includes a plurality of bracket plates, and the plurality of bracket plates are evenly spaced along the length direction of the main channel track side.
[0015] The shelving body includes several uprights arranged in an array. The brackets are detachably fixed to the uprights. At both ends of the main aisle track along its length, one bracket is installed on each upright. Two brackets are installed on each upright between the beginning and end of the main aisle track along its length.
[0016] When the new shuttle travels on the main track, the guide wheels on both sides of the new shuttle contact the inner wall surfaces of the bracket plates on both sides of the main track.
[0017] As a further technical solution of this utility model: the distance between the reference plane of the corbel plate and the reference plane of the main channel track is 10mm.
[0018] As a further technical solution of this utility model: the two ends of the sub-channel guide plate along its length direction are respectively detachably and fixedly connected to the bracket plate.
[0019] As a further technical solution of this utility model: a connecting rod is fixed between the two columns on both sides of the sub-channel track along its width direction.
[0020] In summary, this utility model has at least one of the following beneficial technical effects:
[0021] This utility model discloses a novel rack for shuttle vehicles. It features multiple layers of flat rails on the rack body, and the shuttle's wheels are modified to a flat wheel structure. Several guide brackets are installed on both sides of the main aisle track, and sub-aisle guide plates are installed on both sides of the sub-aisle track. When the shuttle travels on the main aisle track, the guide wheels on both sides of the shuttle contact the guide brackets on both sides of the main aisle track. When the shuttle travels on the sub-aisle track, the guide wheels on both sides of the shuttle contact the sub-aisle guide plates on both sides of the sub-aisle track.
[0022] Compared to existing shelving technologies, this design replaces the high and low rails with a flat rail structure, reducing the gap at the connection points and minimizing or eliminating vibrations when vehicles pass through. Furthermore, the four-way vehicle eliminates the wheel skirts, replacing them with a flat wheel structure. Without the wheel skirts, guide wheels need to be added to both sides of the vehicle, and the shelving also needs side panels to prevent the guide wheels from deflecting laterally. To save costs, the original shelving's cantilever beams are moved outwards to act as guide wheel side panels, improving vehicle safety and stability and extending service life. In this application, the cantilever plate not only serves as a shelving support beam but also as a guide, achieving two functions in one and saving materials.
[0023] The present invention features a small track spacing. In the market, vehicles change direction on the ground by rotating the wheels at the bottom (such as AGVs). The minimum track spacing required for changing direction is the diagonal of the vehicle. Amphibious vehicles change direction directly by raising and lowering the wheels. The minimum track spacing is the width of the wheels on both sides, saving space. Attached Figure Description

[0035] Reference Figure 5This utility model discloses a novel shuttle car-specific shelf, which includes a shelf body 1, and several layers of flat rails 2 are provided on the shelf body 1. The flat rails 2 include a main channel rail 3 and several sub-channel rails 4 vertically arranged on one side of the main channel rail 3.
[0036] The top surface of the main channel track 3 and the top surfaces of several sub-channel tracks 4 are on the same horizontal plane. Main channel guide components are symmetrically arranged on both sides of the main channel track 3.
[0037] Reference Figure 5 Sub-channel guide plates 5 are symmetrically arranged on both sides of the sub-channel track 4. When the new shuttle car travels on the sub-channel track 4, the guide wheels on both sides of the new shuttle car contact the inner wall surfaces of the sub-channel guide plates 5 on both sides of the sub-channel track 4. In this embodiment, the wheels of the new shuttle car moving on the flat track 2 are flat wheels.
[0038] Reference Figure 5 The main aisle track 3 includes two parallel main track rods 31, which are detachably fixed to the shelf body 1. The sub-aisle track 4 includes two parallel sub-track rods 41, which are detachably fixed to the shelf body 1. Several sub-track rods 41 are perpendicular to the main track rods 31. In this embodiment, the sub-track rods 41 are provided with slots that match the size of the main track rods 31. The two main track rods 31 are engaged in the slots on the several sub-track rods 41 and are distributed on both sides of the main aisle track 3.
[0039] The main aisle guide assembly includes several bracket plates 6, which are evenly spaced along the length of the main aisle track 3. The shelf body 1 includes several uprights 11 arranged in an array. The bracket plates 6 are detachably fixed to the uprights 11. At the beginning and end of the main aisle track 3 along its length, one bracket plate 6 is installed on each upright 11. Two bracket plates 6 are installed on each upright 11 between the beginning and end of the main aisle track 3 along its length.
[0040] When the new shuttle travels on the main track 3, the guide wheels on both sides of the new shuttle contact the inner wall surfaces of the bracket plates 6 on both sides of the main track 3. In this embodiment, referring to... Figure 7 A guide ramp 61 is provided on one side of the bracket plate 6. When the guide wheel of the new shuttle car contacts the bracket plate 6, it will be guided to the inner wall surface of the bracket plate 6 by the guide ramp 61, which increases the accuracy of guidance.
[0041] The distance between the reference plane of the bracket plate 6 and the reference plane of the main channel track 3 is 10mm. The two ends of the sub-channel guide plate 5 along its length are detachably fixed to the bracket plate 6. A connecting rod 7 is fixed between the two columns 11 on both sides of the sub-channel track 4 along its width.
[0042] This invention moves the original corbel beam outward, placing it closer to the outer side of the main channel track 3, where it acts as a guide plate for the vehicle's guide wheels, aiding in vehicle movement. For example... Figure 3 The distance between the reference plane 1 of the traditional shelving bracket and the reference plane 2 of the main aisle rail 3 is 50mm. Figure 4 The arrow represents a traditional corbel structure. For example... Figure 6 The distance between the reference plane A1 of the bracket plate 6 and the reference plane A2 of the main aisle track 3 is 10mm. Compared with traditional racks, it has been shifted inward by 40mm, so that it can contact the guide wheels on both sides of the four-way shuttle traveling on the main aisle track 3, thus correcting the deviation of the vehicle during travel. Figure 7 The arrow indicates the Bracket 6 structure. Compared to traditional Brackets, Bracket 6 moves the contact surface of the Bracket upwards to match the height of the vehicle's guide wheels.
[0043] Movement process: Figure 5 This diagram shows the layout of the guide rails. The x-direction is the main aisle direction for the vehicle. If the vehicle deviates to the left while traveling in the x-direction, the left guide wheel on the chassis will contact the a1 and a2 bracket plates 6 to correct the deviation and help the vehicle straighten. If the vehicle deviates to the right, the right guide wheel on the chassis will contact the a3 and a4 bracket plates 6 to correct the deviation and help the vehicle straighten. The y-direction is the sub-aisle guide plate 5, which also serves as a cargo placement rack. In the x-direction main aisle, the vehicle completes wheel reversal at the y-intersection and enters the y-direction track. Simultaneously, if the vehicle deviates to the left, the left guide wheel on the chassis will contact the a5 guide plate to correct the deviation and help the vehicle straighten. If the vehicle deviates to the right, the right guide wheel on the chassis will contact the a6 guide plate to correct the deviation and help the vehicle straighten. At the same time, the vehicle enters under the cargo, and the vehicle is lifted to complete the cargo placement.
