According to different process steps, the pallets and products need to be transported to other workshops together. The current transportation is completed by conventional flatbed carts. Among them, due to the overall weight of the products and pallets, two people are required to carry them from the speed chain line to the cart. During the transportation process, there is also a risk of the product slipping and being injured. In addition, there are other equipment at the docking points of some workstations, and the flatbed cart cannot be close to the workstation. When manually transporting, it is necessary to lift and cross the equipment to place it on the top of the cart.

[0017] The following embodiments of the present invention are described in further detail in conjunction with 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.

[0018] like Figure 1-Figure 5 As shown, the present invention provides a technical solution: a multifunctional trolley, comprising an aluminum alloy frame 1 and a sliding frame 9, a reinforced fixing plate 12 is arranged around the bottom of the aluminum alloy frame 1, and a caster 2 is connected to the lower part of the reinforced fixing plate 12, guide rods 6 are arranged on both sides of the upper surface of the aluminum alloy frame 1, and a linear bearing 7 is sleeved on the surface of the guide rod 6, a sliding frame 9 is fixed to the outer wall of the linear bearing 7, and roller strips 5 are arranged on both sides of the sliding frame 9, and a guide guard plate 4 is fixed to the outer side of the strip plate of the roller strip 5, a supporting wheel 8 is arranged at intervals at the bottom of the sliding frame 9, a one-way check valve 10 is arranged at one end of the sliding frame 9, and a limited locking mechanism 3 and a blocking and limiting device 11 are arranged at the other end of the sliding frame 9, a knob plunger device 13 is threadedly installed on both sides of the aluminum alloy frame 1, the caster 2 and the reinforced fixing plate 12 are arranged one-to-one, and the caster 2 is a polyurethane wheel in the form of a universal belt brake, and the arrangement direction of the supporting wheel 8 is consistent with the guide rod 6. The directions are consistent, and the sliding frame 9 is slidably connected to the aluminum alloy frame 1 through the supporting wheel 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 wheel 8 is rotatably connected to the surface of the aluminum alloy frame 1, and the top surface of the supporting wheel 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 sides of the support plate are in contact with the roller top surface of the roller strip 5. Holes are equidistantly opened 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. 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 the pallet needs to be transported, the multifunctional trolley is manually pushed to the corresponding workstation, and the caster 2 is locked. The caster 2 is a polyurethane wheel in the form of a universal belt 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 workstation, and then the knob plunger device 13 is unscrewed. Since corresponding holes are set 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 full-load state. The supporting wheel 8 is arranged correspondingly under the roller bar 5, which can improve the stability in the full-load state and make it easy for manual handling. 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 process of the trolley, which causes the workpiece to collide. When the pallet needs to be pushed out, the trolley is manually pushed to the corresponding workstation, the caster 2 is locked, the limit locking mechanism 3 and the blocking limit device 11 are opened, and the sliding frame 9 is pushed out in the reverse 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, so as to reduce the thrust requirement. After the pushing is completed, the sliding frame 9 is retracted and restored to the initial state; Based on the above description, the present invention connects the corresponding workstations through a sliding frame 9 that can be telescopically slid in two directions, so that the pallet can be horizontally translated directly from the workstation to the sliding frame 9 without 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 connected to the double-speed chain, so that the pallet transfer process can be easily completed manually.

[0019] In summary, when the multifunctional trolley is in use, considering the comprehensive usage scenarios, the size of the pallet is slightly larger than the size of the product. Limiting the movement of the pallet during transportation can avoid direct collisions between products, that is, the product transportation can be completed by completing the pallet transportation. Combined with the existing speed chain size and the pallet size, two groups of roller bars 5 are arranged on the top of the trolley. The width of the two groups of roller bars 5 is close to the size of the speed chain. The roller bars 5 are arranged without power, and the pallet can slide easily on the roller bars 5. Based on the manual handling quantity requirements, the trolley can place four groups 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, and a blocking and limiting device 11 is provided at the push-out end. During the transportation process of the trolley, it plays a limiting role. When it is necessary to unload the vehicle and push out the pallet, the blocking and limiting device 11 can be lowered to allow the pallet to be pushed out smoothly, and 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 in the forward and reverse directions. 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 the 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, which is beneficial 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 polyurethane wheel in the form of a universal brake is installed at the bottom, which can complete turning and U-turns in a small space. The polyurethane wheel can reduce damage to the ground and is beneficial for indoor use.
