Abstract
Description
Technical Field
[0001] This utility model relates to the field of warehousing equipment technology, and in particular to a bagged coating carrier device. Background Technology
[0002] The rapid turnover of bagged coatings in the warehousing process has become a key factor for coating companies to reduce costs and increase efficiency. In recent years, concepts such as automated storage and retrieval systems (AS / RS) and high-density storage have been widely introduced. Their core lies in replacing manual labor with rail-mounted vehicles to achieve precise movement of goods between shelves. However, given the characteristics of bagged materials—large volume, high center of gravity, and susceptibility to breakage—traditional load-bearing units often struggle to balance high-density layout with operational stability.
[0003] Currently, the industry generally adopts a rigid frame combined with a single-axle drive trolley solution. Fixed casters are mounted at the four corners of the frame, and the trolley moves back and forth using pre-embedded straight or circular tracks in the ground. Steering is accomplished manually or via an external turntable. Some manufacturers add a rotating platform to the track, allowing the trolley to passively change direction at intersections; however, this platform is bulky, slow to respond, and requires an additional power source. Some manufacturers add rubber pads between the frame and wheelset; however, rubber is prone to aging, has limited compression, and still exhibits noticeable vibration under heavy loads. Utility Model Content
[0004] The purpose of this invention is to propose a bagged coating support device to solve the technical problems of existing rigid frames being unable to adapt to the rail surface, large footprint of steering nodes, and significant running impact.
[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows: A bagged paint carrier includes a storage station with a track laid underneath; a base that moves along the track; two sets of steering wheels that are rotatably connected to the bottom of the base and move within the track; a drive wheel that is rotatably disposed on the bottom of the base and located between the two sets of steering wheels; a shock-absorbing mechanism installed between the drive wheel and the base; a first steering mechanism disposed on the bottom of the base to drive the steering wheels to rotate; and a second steering mechanism disposed on the bottom of the base to drive the drive wheel to rotate.
[0006] By adopting the above technical solution, when the base travels on the track, the shock absorption mechanism absorbs the impact caused by the height difference of the rail surface in real time. The steering wheel and the drive wheel are independently controlled by the first and second steering mechanisms respectively, realizing small-radius reversal and reducing the node footprint.
[0007] Furthermore, a shock-absorbing mechanism is provided between the drive wheel and the base, and the second steering mechanism is mounted on the shock-absorbing mechanism.
[0008] By adopting the above technical solution, the shock absorption mechanism and the second steering mechanism are integrated and arranged so that the drive wheel can still maintain reliable contact with the rail surface when steering, reducing the risk of derailment.
[0009] Furthermore, the shock absorption mechanism includes a top plate fixed to the bottom of the base, a bottom plate vertically connected to the bottom of the top plate, a scissor bar rotatably connected between the top plate and the bottom plate, and a shock absorber installed between the top plate and the bottom plate, with the drive wheel rotatably mounted on the bottom plate.
[0010] By adopting the above technical solution, the scissor lift and shock absorber form a liftable buffer platform. The base plate adapts to the undulations of the rail surface, ensuring that the drive wheel always stays in contact with the rail and improving the smoothness of operation.
[0011] Furthermore, the second steering mechanism includes a roller shaft rotatably mounted on the base plate, a gear ring fixed on the roller shaft, and a second motor fixed on the base plate. The output end of the second motor is provided with a gear, which meshes with the gear ring. A bracket is fixedly mounted at the bottom of the roller shaft, and the drive wheel is rotatably mounted on the bracket.
[0012] By adopting the above technical solution, the gear-ring drive achieves precise angle control of the drive wheel, the bracket rotates synchronously with the roller shaft, the structure is compact, and the steering accuracy is high.
[0013] Furthermore, a driven shaft is rotatably mounted on the bracket, the drive wheels are mounted at both ends of the driven shaft, and a third motor for driving the driven shaft to rotate is fixedly mounted on the bracket.
[0014] By adopting the above technical solution, the third motor directly drives the driven shaft, causing the two drive wheels on both sides to rotate synchronously, providing stable traction and reducing slippage.
[0015] Furthermore, the scissor lift consists of two connecting rods rotatably connected at the center. Both the top plate and the bottom plate are provided with strip grooves. One end of the connecting rod is rotatably connected to the top plate and the bottom plate, and the other end is slidably disposed in the strip groove.
[0016] By adopting the above technical solution, the connecting rod slides in the strip groove, making the scissor lift extend and retract smoothly, keeping it parallel during the lifting and lowering process, and avoiding jamming.
[0017] Furthermore, the track includes multiple sets of parallel storage rails and a set of output rails perpendicular to one end of the storage rails, and a circular disk for the steering wheel to rotate is provided at the connection between the storage rails and the output rails.
[0018] By adopting the above technical solution, the circular disc provides a rotation fulcrum for the steering wheel, and the base smoothly transitions between the storage rail and the output rail, improving the reliability of reversing.
[0019] Furthermore, the first steering mechanism includes a lead screw rotatably disposed at the bottom of the base, a first motor driving the lead screw to rotate, a pair of sliders screwed onto the lead screw, a track fixed to the bottom of the base and guiding the sliders to slide, and a push rod rotatably connected between the sliders and the steering wheel.
[0020] By adopting the above technical solution, the rotation of the lead screw drives the slider to move synchronously in the opposite direction, and the push rod pushes the steering wheel to swing precisely. The structure is simple and the action synchronization is good.
[0021] Furthermore, a fixing rod is horizontally fixed on the steering wheel, one end of the push rod is rotatably connected to the slider, and the other end is rotatably connected to one end of the fixing rod. A limiting rod is provided at the bottom of the base to limit the rotation range of the fixing rod.
[0022] By adopting the above technical solution, the limit rod limits the maximum rotation angle of the fixed rod, preventing the steering wheel from over-rotating and ensuring safe reversing.
[0023] Furthermore, the lead screw is provided with two sections of threads with opposite directions, and the two sliders are respectively screwed onto the two sections of threads.
[0024] By adopting the above technical solution, a single lead screw can drive two sliders to move in opposite directions, reducing the number of parts and improving transmission efficiency.
[0025] Compared with the prior art, the present invention has the following beneficial effects: The bagged paint carrier device described in this utility model, through the cooperation of a shock-absorbing mechanism and two sets of independent steering mechanisms, allows the base to travel smoothly on uneven rails and achieve precise reversal with a small radius, significantly improving storage density; the combination of scissor lift and shock absorber enables the base plate to adaptively lift and lower, ensuring that the drive wheels always stay on the rail and reducing the probability of derailment; the gear-ring drive structure is compact, the steering angle is controllable, and the additional footprint is reduced; the lead screw bidirectional thread design enables a single power source to synchronously drive two sliders, simplifying the structure and improving steering synchronization.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model in light of the specific circumstances.
[0032] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0033] This embodiment relates to a bagged paint carrier device, the overall structure of which is as follows: Figure 1 , Figure 2 and Figure 3 As shown, it includes a storage station 1, a track 2, a base 3, a drive wheel 5, and a steering wheel 4.
[0034] Among them, the lower part of the warehouse station 1 is laid with a track 2, the bottom of the base 3 is provided with a drive wheel 5 and a steering wheel 4 that move within the track 2, a shock absorption mechanism 6 is provided between the drive wheel 5 and the base 3, the bottom of the base 3 is provided with a first steering mechanism 7 that drives the steering wheel 4 to adjust the angle, and the shock absorption mechanism 6 is provided with a second steering mechanism 8 that drives the drive wheel 5 to adjust the angle.
[0035] It is worth mentioning that track 2 has a double-track structure, which is divided into storage track 201 and output track 202. There are multiple sets of storage track 201 arranged in parallel at the bottom of warehouse station 1. Each set of storage track 201 is equipped with multiple sets of base trays 3 for carrying bagged paint. The output track 202 is a set located at one end of the storage track 201 and arranged vertically. When materials need to be transported to the outside, the base trays 3 move from the storage track 201 to the output track 202, and then from the output track 202 to the outlet. It is only necessary to move the truck or other transportation vehicle to the outlet of the output track 202. This setting facilitates the transportation of goods and improves the transportation efficiency.
[0036] Furthermore, a circular disk 203 is provided at the connection between the storage rail 201 and the output rail 202 for the steering wheel 4 to rotate. When the base 3 moves to the connection between the storage rail 201 and the output rail 202, the steering wheel 4 is positioned exactly at the circular disk 203. The first steering mechanism 7 drives the steering wheel 4 to rotate, ensuring that the steering wheel 4 is parallel to the output rail 202. The second steering mechanism 8 drives the drive wheel 5 to remain parallel to the steering wheel 4, ensuring that the base 3 can move along the rail 2. This enables the base 3 to automatically turn along the rail 2, ensuring... The storage station 1 can be filled with bagged paint. Two sets of steering wheels 4 are arranged opposite each other on the base 3. The drive wheel 5 is located between the two sets of steering wheels 4. The steering wheels 4 can ensure the stability of the base 3 when it moves. The drive wheel 5 can ensure that the base 3 moves within the storage station 1. The storage rail 201 between the output rails 202 has an opening for the drive wheel 5 to pass through. This arrangement ensures the smooth movement of the base 3. The shock absorption mechanism 6 ensures that the drive wheel 5 can contact the ground and prevent the base 3 from bumping when it moves.
[0037] Based on the above overall introduction, this embodiment presents an exemplary structure of the bagged paint carrier device, such as... Figure 4 and Figure 5 As shown, the shock absorption mechanism 6 includes a top plate 601 fixedly installed at the bottom of the base support 3, a bottom plate 602 lifted and lowered below the top plate 601, a scissor bar 603 rotatably connected between the top plate 601 and the bottom plate 602, a shock absorber 604 installed between the top plate 601 and the bottom plate 602, and a drive wheel 5 rotatably installed on the bottom plate 602.
[0038] It should be noted that the top plate 601 is fixedly installed at the bottom of the base 3. One end of the scissor lift 603 is rotatably connected to the base plate 602 and the top plate 601, while the other end is slidably mounted on the top plate 601 and the base plate 602. Multiple shock absorbers 604 are provided and installed between the top plate 601 and the base plate 602. The shock absorbers 604 are common shock-absorbing devices in the prior art, and their specific structure will not be described in detail here. They can simply be fixedly installed on the top plate 601 and the base plate 602 with nuts. The scissor lift 603 consists of two connecting rods 6031. The top plate 601 and The base plate 602 has a strip groove 6032 for sliding two connecting rods 6031. The two connecting rods 6031 are rotatably connected in the middle, with one end rotatably connected to the top plate 601 and the base plate 602, and the other end slidably disposed in the strip groove 6032. This arrangement ensures that the base plate 602 can be raised and lowered. The scissor lift 603 ensures the stability of the base plate 602 when it is raised and lowered. The shock absorber 604 ensures that the base support 3 reduces bumps. The drive wheel 5 can follow the rise and fall of the base plate 602. The steering wheel 4 moves within the track 2. This arrangement can reduce the bumps of the base support 3.
[0039] As a preferred implementation method, such as Figure 6 , Figure 7 and Figure 8As shown, the first steering mechanism 7 in this embodiment includes a lead screw 701 rotatably disposed at the bottom of the base 3, a first motor 702 that drives the lead screw 701 to rotate, and a slider 703 screwed onto the lead screw 701. A guide rail 704 is fixedly disposed at the bottom of the base 3. The slider 703 is slidably disposed on the guide rail 704. A push rod 705 is rotatably disposed on the slider 703. The other end of the push rod 705 is rotatably connected to the steering wheel 4.
[0040] It should be noted that the lead screw 701 has two threads with opposite directions. Two sliders 703 are screwed onto these two threads respectively. When the first motor 702 drives the lead screw 701 to rotate, the lead screw 701 causes the two sliders 703 to move closer or further apart. The guide rail 704 restricts the rotation of the sliders 703, ensuring that the sliders 703 can only move along the axial direction of the lead screw 701. When the sliders 703 move, they drive the push rod 705 to move, which in turn pushes the steering wheel 4 to rotate. A fixing rod 10 is horizontally mounted on the steering wheel 4. The push rod 705 and one end of the fixed rod 10 are rotatably connected. This arrangement ensures that the push rod 705 can push the steering wheel 4 to rotate. The bottom of the base 3 is provided with a limit rod 706. The two ends of the fixed rod 10 stop rotating after rotating to the limit rod 706, ensuring that the steering wheel 4 can stop at the limit rod 706 after rotating, thus preventing the steering wheel 4 from shaking. The limit rod 706 can limit the maximum rotation angle of the steering wheel 4 to 90°. This arrangement ensures that the base 3 can move from the storage rail 201 to the output rail 202, and then from the output rail 202 to the outlet.
[0041] As a preferred implementation method, such as Figure 9 As shown, the second steering mechanism 8 in this embodiment includes a roller shaft 801 rotatably mounted on the base plate 602, a gear ring 802 fixedly mounted on the roller shaft 801, and a second motor 803 fixedly mounted on the base plate 602. A gear 804 is fixedly mounted on the second motor 803, and the gear 804 and the gear ring 802 are meshed together. The drive wheel 5 is rotatably connected to the roller shaft 801.
[0042] It should be noted that the bottom of the roller shaft 801 is fixedly mounted with a bracket 805, and the drive wheel 5 is rotatably mounted on the bracket 805. The roller shaft 801 and the base plate 602 are connected by bearings. The second motor 803 is a servo motor. After the second motor 803 starts, it drives the gear 804 to rotate. The gear 804 meshes with the gear ring 802, thereby enabling the gear ring 802 to drive the roller shaft 801 to rotate. This arrangement ensures that the bracket 805 and the drive wheel 5 can rotate together. The second motor 803 can control the drive wheel 5 to rotate at a maximum angle of 90°. This arrangement ensures that the drive wheel 5 can rotate to be parallel to the steering wheel 4, thereby driving the base support 3 to move within the track 2.
[0043] In addition, a third motor 9 is provided on the bracket 805 to drive the drive wheel 5 to rotate. A driven shaft 11 is rotatably provided on the bracket 805, and drive wheels 5 are respectively provided at both ends of the driven shaft 11. The third motor 9 can drive the driven shaft 11 to rotate, and the driven shaft 11 drives the drive wheel 5 to rotate. This arrangement can provide power to the base 3.
[0044] In this embodiment, the bagged paint carrying device, through the cooperation of the shock absorption mechanism 6 and two sets of independent steering mechanisms, allows the base support 3 to travel smoothly on uneven rail surfaces and achieve precise small-radius reversal, significantly improving storage density; the combination of the scissor lift 603 and the shock absorber 604 enables the base plate 602 to adaptively rise and fall, ensuring that the drive wheel 5 always stays on the rail and reducing the probability of derailment; the gear 804-gear ring 802 transmission structure is compact, the steering angle is controllable, and the additional footprint is reduced; the two-way thread design of the lead screw 701 enables a single power source to synchronously drive the two sliders 703, simplifying the structure and improving steering synchronization.
[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
