Description

Technical Field

[0001] This utility model relates to the field of guide wheel technology, and in particular to a foldable portable guide wheel assembly. Background Technology

[0002] Guide wheels are widely used in many scenarios such as industrial production, logistics and transportation, and the movement of mechanical equipment, as important components that guide the direction of movement and assist in the movement of equipment.

[0003] Currently, most traditional guide wheel assemblies on the market are fixed structures, with their guide wheels always in an extended state. When the equipment is idle, being moved, or stored, the fixed guide wheels cannot be retracted, causing the guide wheel assembly to occupy a large amount of space. When some large mechanical equipment needs to be transported over long distances, the fixed guide wheels will increase the overall size of the equipment, making it difficult to meet the space constraints of transport vehicles and increasing transportation costs. At the same time, when facing complex and changing working scenarios such as narrow passages, stairwells, or areas with obstacles, the fixed guide wheels cannot flexibly adjust their position, making it easy for collisions to occur when the equipment is moved. This may not only damage the guide wheels and the equipment itself, but also affect work efficiency and even create safety hazards. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a foldable portable guide wheel assembly.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A foldable portable guide wheel assembly includes a support base, a support frame fixedly connected to the outer wall of the support base, a set of hinged mounting seats fixedly connected to the top outer wall of the support frame, a T-shaped connecting block connected between the hinged mounting seats via a pivot, an auxiliary support plate fixedly connected to the outer wall of the T-shaped connecting block, an auxiliary connecting block connected to one side of the auxiliary support plate via a central shaft, a folding transmission arm connected to one side of the auxiliary connecting block via a pivot, a transmission arm connecting block hinged to one side of the folding transmission arm, a support column fixedly connected to the bottom of the transmission arm connecting block, and guide wheels connected to the outer wall of the support column via an axle.

[0007] Preferably, one end of the T-shaped connecting block is fixedly connected to a connecting rod, and the end of the connecting rod is connected to an electric cylinder via a connector. A set of hinged bases is fixedly connected to the outer wall of the support frame, and a first connecting plate is connected between the hinged bases via a rotating shaft. A central rod is connected to the bottom of the first connecting plate via a connector, and the output end of the electric cylinder is connected to the end of the central rod.

[0008] Preferably, two sets of hinge blocks are fixedly connected to the outer wall of the support column near the support frame. One set of hinge blocks located above the support column is hinged to one end of the first connecting plate. Three positioning blocks are fixedly connected to the outer wall of the support frame. A second connecting plate is connected between two adjacent positioning blocks through a rotating shaft. One end of the second connecting plate is hinged to a set of hinge blocks located below the support column.

[0009] Preferably, a fixing block is fixedly connected to the side of the support column near the support frame, and a support connecting rod is connected between the fixing block and two adjacent positioning blocks.

[0010] The beneficial effects of this utility model are:

[0011] The electric cylinder pulls the center rod and the first connecting plate upwards to rotate counterclockwise. When the first connecting plate rotates, it drives the hinge block to pull the support column and guide wheel to move. Then, it drives the transmission arm connecting block to rotate upwards around the hinge point. This causes one end of the folding transmission arm to move downwards and retract inwards around the hinge point where the auxiliary support plate and the auxiliary connecting block are connected. Then, the auxiliary support plate rotates downwards, realizing the retraction and folding of the folding transmission arm and the auxiliary support plate. At the same time, it completes the folding and storage of the guide wheel, effectively reducing the overall volume of the guide wheel assembly. This solves the problem of traditional fixed guide wheels occupying a lot of space when idle, transported, and stored, making them more portable, facilitating equipment transportation, and reducing transportation costs.

[0012] During the movement of the guide wheel, it rotates through the second connecting plate on the supporting column and the supporting rod on the supporting column, with the pivot between the positioning block and the second connecting plate as the fulcrum. This ensures the stability of the guide wheel assembly during the folding and retracting movement, guarantees the consistency of the guide wheel's folding and retracting movement, and makes the overall equipment operation safe and reliable, effectively improving work efficiency.

The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0021] Example:

[0022] Reference Figure 1-3 A foldable portable guide wheel assembly includes a support base 1, a support frame 2 fixedly connected to the outer wall of the support base 1, a set of hinged mounting seats 3 fixedly connected to the top outer wall of the support frame 2, a T-shaped connecting block 4 connected between the hinged mounting seats 3 via a pivot, an auxiliary support plate 5 fixedly connected to the outer wall of the T-shaped connecting block 4, an auxiliary connecting block 6 connected to one side of the auxiliary support plate 5 via a central shaft, a folding transmission arm 7 connected to one side of the auxiliary connecting block 6 via a pivot, a transmission arm connecting block 8 hinged to one side of the folding transmission arm 7, a support column 9 fixedly connected to the bottom of the transmission arm connecting block 8, and a guide wheel 11 connected to the outer wall of the support column 9 via a wheel axle 10.

[0023] One end of the T-shaped connecting block 4 is fixedly connected to a connecting rod 12. The end of the connecting rod 12 is connected to an electric cylinder 13 via a connector. A set of hinged bases 14 are fixedly connected to the outer wall of the support frame 2. A first connecting plate 15 is connected between the hinged bases 14 via a rotating shaft. The bottom of the first connecting plate 15 is connected to a center rod 16 via a connector. The output end of the electric cylinder 13 is connected to the end of the center rod 16.

[0024] Two sets of hinge blocks 17 are fixedly connected to the outer wall of the support column 9 near the support frame 2. The set of hinge blocks 17 located above the support column 9 is hinged to one end of the first connecting plate 15. Three positioning blocks 18 are fixedly connected to the outer wall of the support frame 2. A second connecting plate 19 is connected between two adjacent positioning blocks 18 through a rotating shaft. One end of the second connecting plate 19 is hinged to a set of hinge blocks 17 located below the support column 9.

[0025] A fixing block 20 is fixedly connected to the side of the support column 9 near the support frame 2, and a support connecting rod 21 is connected between the fixing block 20 and the two adjacent positioning blocks 18.

[0026] In this embodiment, when the guide wheel 11 is used for transportation and needs to be stored or moved, the electric cylinder 13 is first activated. When the electric cylinder 13 retracts, it pulls the central rod 16 upwards, rotating it around the pivot point connecting the hinge base 14 and the first connecting plate 15. When the central rod 16 rotates, it drives the first connecting plate 15 to rotate counterclockwise. When the first connecting plate 15 rotates, it drives the hinge block 17 to pull the support column 9 to rotate. Thus, when the support column 9 rotates, it drives the guide wheel 11 on one side to move around the pivot point connecting the hinge base 14 and the first connecting plate 15, causing the guide wheel 11 to retract towards the support frame 2. When the guide wheel 11 moves, it simultaneously drives the transmission... The arm connecting block 8 rotates upward around the hinge point between the folding transmission arm 7 and the transmission arm connecting block 8. Due to the constraint of the hinge point, when the transmission arm connecting block 8 moves, one end of the folding transmission arm 7 moves downward and retracts inward around the hinge point connecting the auxiliary support plate 5 and the auxiliary connecting block 6 under the action of the transmission arm connecting block 8. Thus, when the folding transmission arm 7 moves, it will drive the auxiliary support plate 5 to rotate downward around the connection point between the hinge mounting base 3 and the T-shaped connecting block 4. Finally, the folding transmission arm 7 and the auxiliary support plate 5 are retracted and folded, completing the storage of the guide wheel 11. This effectively reduces the overall volume of the guide wheel 11, which is beneficial for the transportation or storage of the guide wheel 11, making it more portable.

[0027] Furthermore, during the movement of the guide wheel 11, the second connecting plate 19 on one side and the supporting connecting rod 21 are driven by the support column 9 to rotate around the pivot between the positioning block 18 and the second connecting plate 19. This ensures the stability of the guide wheel 11 during the folding and retraction process, guarantees the consistency of each folding and retraction movement of the guide wheel 11, and makes the overall equipment operation safe and reliable, effectively improving work efficiency and reducing transportation costs.
