[0022] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0023] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a multifunctional trolley, comprising an aluminum alloy frame 1 and a sliding frame 9, the bottom of the aluminum alloy frame 1 is provided with a reinforced fixing plate 12 around, and the lower part of the reinforced fixing plate 12 is connected to the caster 2, the upper surface of the aluminum alloy frame 1 is provided with a guide rod 6, and the surface of the guide rod 6 is sleeved with a linear bearing 7, the outer wall of the linear bearing 7 is fixed with a sliding frame 9, and the two sides of the sliding frame 9 are provided with a roller strip 5, the outer side surface of the strip plate of the roller strip 5 is fixed with a guide guard plate 4, the bottom of the sliding frame 9 is provided with a supporting wheel 8, one end of the sliding frame 9 is provided with a one-way check valve 10, and the other end of the sliding frame 9 is provided with a limited locking mechanism 3 and a blocking limit device 11, the two sides of the aluminum alloy frame 1 are threaded with a knob plunger device 13, the caster 2 and the reinforced fixing plate 12 are arranged one to one, and the caster 2 is a universal polyurethane wheel with a brake, the arrangement direction of the supporting wheel 8 is consistent with the guide rod 6 is consistent in direction, and the sliding frame 9 is slidably connected to the aluminum alloy frame 1 through the supporting roller 8, linear bearing 7, and guide rod 6. The limit locking mechanism 3 and the blocking limit device 11 are symmetrically distributed about the central axis of the aluminum alloy frame 1, and the number of the limit locking mechanism 3 and the blocking limit device 11 is one. The supporting roller 8 is rotatably connected to the surface of the aluminum alloy frame 1, and the top surface of the supporting roller 8 is in contact with the bottom of the sliding frame 9. The end of the sliding frame 9 close to the one-way check valve 10 is the entry end, and the end of the sliding frame 9 close to the limit locking mechanism 3 and the blocking limit device 11 is the push-out end. The roller strip 5 is located between the guide guard plate 4, and the guide guard plate 4 and the sliding frame 9 and the roller strip 5 form a "concave" shape structure. A support plate is placed on the surface of the sliding frame 9, and the bottom two sides of the support plate are in contact with the roller top surface of the roller strip 5. Holes are equidistantly provided on both sides of the sliding frame 9, and the height of the holes is consistent with the height of the knob plunger device 13.
[0024] The specific operation is as follows: first, the end of the sliding frame 9 close to the one-way check valve 10 is the entry end, and the end of the sliding frame 9 close to the limit locking mechanism 3 and the blocking limit device 11 is the push-out end. Based on this, when it is necessary to transport the pallet, the multifunctional trolley is manually pushed to the corresponding work station, and the caster 2 is locked. The caster 2 is a polyurethane wheel in the form of a universal brake to prevent the pallet and its surface from moving during transportation. The limit locking mechanism 3 and the blocking limit device 11 are opened, and the sliding frame 9 is manually pushed out to extend outward from the entry end and contact the work station, and then the knob plunger device 13 is unscrewed. Since corresponding holes are provided on both sides of the sliding frame 9, after the multifunctional trolley stops, the extension distance of the sliding frame 9 is manually adjusted. The hole position on its side is aligned with the knob plunger device 13, and then the knob plunger device 13 is rotated to make it correspond to the hole position to complete the locking. Multiple groups of pallets can enter the trolley through the roller bar 5. The one-way check valve 10 can prevent the pallet from retreating when the pallet moves to the surface of the sliding frame 9. After the pallet enters, the sliding frame 9 is retracted and restored to its initial state. During the telescopic movement of the sliding frame 9, the linear bearing 7 and the guide rod 6 can facilitate the linear sliding of the fully loaded state. The supporting wheel 8 is arranged correspondingly under the roller bar 5, which can improve the stability in the fully loaded state and make it easy for manual labor to complete the handling process. The guide guard plate 4 facilitates the directional consistency of the pallet during the handling process, and at the same time reduces the movement of the pallet during the pushing of the trolley, which causes the workpiece to be bumped.
[0025] When the pallet needs to be pushed out, the trolley is manually pushed to the corresponding work station, the casters 2 are locked, the limit locking mechanism 3 and the blocking limit device 11 are opened, and the sliding frame 9 is pushed out in the opposite direction, that is, the sliding frame 9 extends outward from the pushing end, and then the knob plunger device 13 is rotated out to complete the locking with the sliding frame 9, and the blocking part of the blocking limit device 11 is lowered, and the pallets can be pushed out one by one. During the pushing process, rolling friction occurs between the two sides of the bottom of the pallet and the roller parts on the roller bar 5 to reduce the thrust requirement. After the pushing is completed, the sliding frame 9 is retracted and restored to the initial state.
[0026] Based on the above description, the utility model connects to the corresponding workstations through a sliding frame 9 that can be telescopically slid in two directions, so that the pallet can be directly horizontally moved from the workstation to the sliding frame 9 without the need for manual lifting and transportation, and avoiding the risk of the product slipping and injuring people. The roller bar 5 and the guide guard plate 4 are used to ensure the directional consistency of the pallet during transportation and translation, while reducing the thrust requirement, thereby facilitating manual operation and reducing labor intensity. It can also be docked with a double-speed chain, allowing manual labor to easily complete the pallet transfer process.
[0027] In summary, when the multifunctional trolley is used, the size of the pallet is slightly larger than the size of the product, and limiting the movement of the pallet during transportation can avoid direct collisions between products. That is, the product transportation can be completed after the pallet transportation is completed. Combined with the existing speed chain size and the pallet size, two sets of roller bars 5 are arranged on the top of the trolley. The width of the two sets of roller bars 5 is close to the size of the speed chain. The roller bars 5 adopt a non-powered arrangement, and the pallet can slide easily on the roller bars 5. Based on the manual handling quantity requirements, the trolley can place four sets of pallets at a time. Considering the ease of pallet transportation, the length of the roller bars 5 is consistent with the length of the trolley, one end is used for the pallet to enter, and the other end is used for pushing out. A one-way check valve 10 is provided at the entry end to ensure that the pallet cannot slide out and fall after entering. A blocking limit device 11 is provided at the push-out end, which plays a limiting role during the trolley transportation process. When it is necessary to unload the car and push out the pallet, the blocking limit device 11 can be lowered to allow the pallet to be pushed out smoothly. A guide guard plate is provided on the side of the roller bar 5. 4. It can not only realize the conveying guidance but also limit the left and right position of the pallet to avoid the left and right movement of the pallet during the transportation of the trolley. Considering the docking at special workstations, the trolley is designed with a sliding frame 9, which can be extended forward and reverse. The extension distance is consistent with the distance required to be crossed on site. The roller bars 5 used to carry the pallet are installed on both sides of this sliding frame 9. The extension height is consistent with the height of the docking equipment. After extension, docking can be achieved, so that the pallet can be entered or pushed out. The sliding mechanism adopts the form of a guide rod 6 plus a linear bearing 7. A supporting wheel 8 is installed on the outside of the guide rod 6 to reduce the force on the guide rod 6 body and increase the overall stability. The slide-out mechanism is designed with a limited locking mechanism 3, which can be locked in different forward and reverse extension states and retracted states to avoid shaking and sliding out during the transportation of the trolley. The trolley adopts an aluminum alloy frame 1 as a whole, and a universal polyurethane wheel with a brake is installed at the bottom. It can complete turning and U-turns in a small space. The polyurethane wheel can reduce damage to the ground and is conducive to indoor use.
