Anti-overturning box shuttle vehicle

Abstract

This utility model discloses an anti-tipping box-type shuttle. Each of the limiting mechanisms includes a mounting frame. Slide rails are provided on both sides of the inner wall of the mounting frame, and each slide rail extends vertically. A slider is slidably connected to the inner wall of each slide rail. A lifting plate is fixedly installed between adjacent sliders. A clamping wheel is embedded in and rotatably connected to the lower back of the lifting plate. Three clamping wheels are provided, equidistantly arranged in a horizontal straight line. A horizontally rotatable clamping wheel is provided on the surface of each lifting plate near the outer wall of the shuttle track. The clamping wheel abuts against the shuttle track. When the shuttle moves, the clamping wheel slides along the side of the track, thus avoiding excessive friction that could affect the normal movement of the shuttle. When cargo transfer causes the shuttle's center of gravity to shift, the clamping wheel abuts against the side of the track, thus preventing the shuttle from tipping over to one side.

Description

Technical Field

[0001] This utility model relates to the field of shuttle vehicle technology, specifically to a box-type shuttle vehicle designed to prevent tipping over. Background Technology

[0002] Box-type shuttles are automated warehousing equipment specifically designed for handling lightweight goods. They are suitable for scenarios such as e-commerce warehouses and retail distribution centers that require high-density storage and rapid "goods-to-person" picking. They improve warehouse space utilization and order processing efficiency through efficient small-item sorting capabilities.

[0003] Box-type shuttle cars typically have telescopic forks on both sides inside as grippers for picking up and placing goods. When the telescopic forks extend and retract, moving the goods above the box-type shuttle car, or transferring the goods to the outside of the box-type shuttle car, the center of gravity of the shuttle car may shift, which may lead to the risk of the shuttle car car overturning above the track. To address this issue, an anti-overturning box-type shuttle car is proposed. Utility Model Content

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] An anti-tipping box-type shuttle car includes a shuttle car body, and the front and back sides of the shuttle car body are provided with limit mechanisms, and a total of four limit mechanisms are provided.

[0006] Each of the aforementioned limiting mechanisms includes a mounting frame, and slide rails are provided on both sides of the inner wall of the mounting frame. Each slide rail extends in a vertical direction, and a slider is slidably connected to the inner wall of each slide rail. A lifting plate is fixedly installed between adjacent sliders. A clamping wheel is embedded in and rotatably connected to the lower back of the lifting plate. There are three clamping wheels in total, and each clamping wheel is equidistantly arranged in a horizontal straight line direction.

[0007] As a further embodiment of this utility model: a support column is fixedly connected to the center of the side of the lifting plate away from the clamping wheel. Threaded holes are provided at the top and bottom of the support column. An auxiliary wheel is fitted and rotatably connected to the outer wall of the support column. The diameter of the auxiliary wheel is larger than the width of the lifting plate. An anti-collision sleeve is fitted on the outer wall of the auxiliary wheel.

[0008] As a further embodiment of this utility model: a limiting ring is sleeved on the outer wall of the support column and in front of the auxiliary wheel. Screws are connected through the middle of the top and bottom surfaces of the limiting ring, and the ends of each screw are fastened to the internal threads of different threaded holes.

[0009] As a further embodiment of this utility model: an upper magnet is bonded and fixed to the middle of the top surface of the inner wall of the mounting frame, a lower magnet is provided directly below the upper magnet, the bottom surface of the lower magnet is bonded and fixed to the lifting plate, and the top surface of the lower magnet and the bottom surface of the upper magnet have the same magnetic poles.

[0010] As a further embodiment of this utility model: fixing ears are fixedly installed on both sides of the outer wall of the mounting frame, and an operation window is opened at the lower middle part of the surface of the mounting frame, and the interior of the operation window is connected through the support column.

[0011] As a further embodiment of this utility model: a pad is provided on the back of the mounting frame, and several through holes are provided on both sides of the surface of the pad, and each through hole is aligned with the hole on the surface of the fixing ear.

[0012] As a further embodiment of this utility model: the main body of the shuttle includes a chassis, and a car head is fixedly installed on both sides of the chassis. Wheels are rotatably connected to both sides of the outer wall of each car head. The front and back of the chassis abut against the pad, and the surface of the chassis is fixedly connected to the pad and the fixing lug by bolts.

[0013] The beneficial effects of this utility model are:

[0014] (1) The present invention provides a lifting plate structure on the outside of the main chassis of the shuttle car. There are four lifting plates and they are distributed on both sides of the outside of the shuttle car track. Each lifting plate is provided with a horizontally rotating clamping wheel on the surface of the outer wall of the shuttle car track. The clamping wheel abuts against the shuttle car track. When the shuttle car moves, the clamping wheel slides along the side of the track at the same time, thereby avoiding excessive friction that affects the normal movement of the shuttle car. When the transfer of goods causes the center of gravity of the shuttle car to shift, the clamping wheel abuts against the side of the track, thereby preventing the shuttle car from tilting to one side.

[0015] (2) The outer wall of the lifting plate is also equipped with auxiliary wheels for protection. When the lifting plate moves close to the crossbeam supporting the shuttle car track, the crossbeam first contacts the arc surface of the lower side of the auxiliary wheel. When the shuttle car continues to move along the track, the lifting plate will be subjected to a vertical upward thrust, and the lifting plate can be lifted to avoid collision with obstacles such as the crossbeam structure.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-5 As shown, the anti-tipping box-type shuttle includes a shuttle body 1. Limiting mechanisms 2 are provided on both the front and back sides of the shuttle body 1, with a total of four limiting mechanisms 2. Each limiting mechanism 2 includes a mounting frame 201. Slide rails 207 are provided on both sides of the inner wall of the mounting frame 201. Each slide rail 207 extends vertically, and a slider 210 is slidably connected to the inner wall of each slide rail 207. A lifting plate 208 is fixedly installed between adjacent sliders 210. Clamping wheels 211 are embedded in and rotatably connected to the lower back of the lifting plate 208. Three clamping wheels 211 are provided, and each clamping wheel 211 is equidistantly arranged in a horizontal straight line direction. Figure 1 , Figure 4 As shown, the clamping wheel 211 can abut against the outer surface of the shuttle track, while the mounting frame 201 is located above the shuttle track.

[0025] A support column 212 is fixedly connected to the center of the side of the lifting plate 208 away from the clamping wheel 211. Threaded holes 213 are provided at both the top and bottom of the support column 212. An auxiliary wheel 214 is fitted and rotatably connected to the outer wall of the support column 212. The diameter of the auxiliary wheel 214 is larger than the width of the lifting plate 208. An anti-collision sleeve 215 is fitted onto the outer wall of the auxiliary wheel 214. Figure 5As shown, the anti-collision sleeve 215 is made of silicone, which buffers the impact received by the auxiliary wheel 214.

[0026] A limiting ring 216 is fitted on the outer wall of the support column 212 and in front of the auxiliary wheel 214. Screws 217 are threaded through the top and bottom surfaces of the limiting ring 216, and the ends of each screw 217 are fastened to the internal threads of different threaded holes 213. Figure 5 As shown, the limiting ring 216 prevents the auxiliary wheel 214 from coming off the outside of the support column 212.

[0027] An upper magnet 206 is glued and fixed to the center of the top surface of the inner wall of the mounting frame 201. A lower magnet 209 is positioned directly below the upper magnet 206. The bottom surface of the lower magnet 209 is glued and fixed to the lifting plate 208. The top surface of the lower magnet 209 has the same magnetic poles as the bottom surface of the upper magnet 206. Figures 3-4 As shown, the upper magnet 206 pushes the lower magnet 209 to descend, thereby causing the lifting plate 208 to fall and reset.

[0028] Fixing ears 202 are fixedly installed on both sides of the outer wall of the mounting frame 201. An operation window 205 is opened at the lower middle part of the surface of the mounting frame 201, and the interior of the operation window 205 is connected to the support column 212.

[0029] A pad 203 is provided on the back of the mounting frame 201. Several through holes 204 are formed on both sides of the surface of the pad 203, and each through hole 204 is aligned with a hole on the surface of the fixing ear 202. Figure 2 As shown, the through hole 204 allows the operator to easily lubricate the support column 212, thereby facilitating the rotation of the auxiliary wheel 214 around the support column 212.

[0030] The shuttle vehicle body 1 includes a chassis 101, with a front end 102 fixedly mounted on both sides of the chassis 101. Wheels 103 are rotatably connected to both sides of the outer wall of each front end 102. The front and back of the chassis 101 abut against a pad 203, and the surface of the chassis 101 is fixedly connected to the pad 203 and the fixing lugs 202 by bolts. Figure 2 As shown, the distance between the limiting mechanisms 2 can be adjusted by adding different numbers of stainless steel pads 203.

[0031] The working principle of this utility model:

[0032] The chassis 101 has mounting holes on both the front and back. The fixing lugs 202 abut against the side surface of the chassis 101, and bolts are threaded through the fixing lugs 202 and tightened into the mounting holes. The limiting mechanism 2 is thus installed. After installation, it must be ensured that the lifting plate 208 is located outside the shuttle track, and the clamping wheels 211 are in contact with the outer surface of the shuttle track. Therefore, when the shuttle body 1 tilts, the clamping wheels 211 abut against the track surface, thus providing auxiliary support for the shuttle body 1. Figure 2 As shown, a pad 203 can be added to the back of the mounting frame 201 to adjust the distance between the two lifting plates 208 in the width direction of the shuttle body 1, so as to ensure that the clamping wheel 211 clamps the track stably.

[0033] In addition, when the shuttle body 1 drives the limiting mechanism 2 to move in a straight line along the track and approaches the crossbeam supporting the side of the track, the anti-collision sleeve 215, supported by the auxiliary wheel 214, will first abut against the corner of the crossbeam structure. Since the lower arc side of the auxiliary wheel 214 is squeezed, the auxiliary wheel 214 can be subjected to a vertical upward component force, which can then drive the lifting plate 208 to rise to avoid obstacles. After passing the crossbeam structure and other obstacles, the upper magnet 206 pushes the lower magnet 209 away, and then the lifting plate 208 falls back to its original position, and the clamping wheel 211 abuts against the track surface again.

[0034] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
