For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0027] refer to Figures 1 to 5 A dual-purpose trolley for material transportation in a coating production line includes: a bottom plate 1, a universal wheel 2, and a push handle 3. The bottom plate 1 is made of a rectangular steel plate, and the bottom of the bottom plate 1 is reinforced by welding reinforcing ribs. The universal wheel 2 is installed under the bottom plate 1, and the universal wheel 2 is a universal wheel 2 with a brake. The push handle 3 is welded to the top of the bottom plate 1, and the push handle 3 is located on one side of the short side of the rectangular bottom plate 1; four sleeves 4 are vertically arranged on the bottom plate 1, and the sleeve 4 is square, hollow and has an open top. A pillar 5 is vertically slidably installed inside each of the sleeves 4, and the four pillars A top plate 6 is fixed to the top of the column 5, and a top rod bin 7 is installed on the side wall of each sleeve 4. A support rod 8 for supporting the bottom of the pillar 5 is installed inside the top rod bin 7. The support rod 8 is a solid metal square rod. The top rod bin 7 is connected to the sleeve 4 and the support rod 8 can slide horizontally between the top rod bin 7 and the sleeve 4. A horizontal guide groove 9 is commonly opened between each top rod bin 7 and the side wall of the sleeve 4. A guide rod 10 is horizontally fixed on the support rod 8. The guide rod 10 passes through the guide groove 9 and can slide horizontally inside the guide groove 9.

[0028] During normal use, the bottom of the pillar 5 directly abuts the bottom of the sleeve 4, and the top of the top plate 6 and the space between the top plate 6 and the bottom plate 1 can store materials. The double-layer platform improves the transport vehicle's ability to transfer coating materials, thereby improving the production efficiency of the coating production line. When the space between the top plate 6 and the bottom plate 1 is insufficient to transfer larger materials such as asphalt silencer panels, the top plate 6 can be pulled up, and then the guide rod 10 can be pushed horizontally along the guide groove 9 by hand, so that each support rod 8 moves to the bottom of the pillar 5, and then the top plate 6 is lowered, and the pillar 5 finally falls on the top of the support rod 8. At this time, the space between the top plate 6 and the bottom plate 1 can be expanded, which is convenient for the transport vehicle to load larger volumes of materials, further improving the applicability of the transport vehicle to different materials, and thereby increasing the transfer rate.

[0029] In order to improve the safety of the transport trolley during transportation and prevent the pillar 5 from sliding off the top of the support rod 8 during transportation, a limit sleeve 11 is vertically fixedly installed on each sleeve 4, a slide groove 12 is vertically opened at the bottom of the limit sleeve 11, a lock tongue 13 is slidably installed inside the slide groove 12, and a spring 14 is arranged between the lock tongue 13 and the bottom of the slide groove 12, and the spring 14 is used to keep the lock tongue 13 extending out of the slide groove 12. When the lock tongue 13 extends out of the slide groove 12, the lock tongue 13 spans the upper and lower sides of the guide groove 9. When the guide rod 10 is moved along the guide groove 9 and the support rod 8 is moved under the pillar 5, when the guide rod 10 passes the locking tongue 13, it abuts against the inclined side of the locking tongue 13. After the locking tongue 13 is subjected to force, the spring 14 is compressed and retracts into the inside of the slide groove 12. When the guide rod 10 passes the locking tongue 13, the spring 14 pushes the locking tongue 13 out of the slide groove 12 again. At this time, if the guide rod 10 contacts the locking tongue 13 again, it will contact the non-inclined surface of the locking tongue 13, and the guide rod 10 cannot squeeze the locking tongue 13 back into the slide groove 12. This prevents the support rod 8 from sliding back into the top rod bin 7 during transportation, causing the pillar 5 to slide from the top of the support rod 8 to cause a safety accident, thereby improving the transportation safety of the conveying trolley.

[0030] In order to further improve the applicability of the conveying trolley to different materials and improve the convenience and efficiency of material conveying, the top plate 6 includes an outer frame 601 and an inner plate 602. The outer frame 601 is fixedly connected to the four pillars 5. A limit slot is horizontally provided on the outer frame 601, and the inner plate 602 is horizontally slidably installed inside the limit slot. When it is necessary to transport higher materials, such as struts and long clamps, if the materials are placed on the top plate 6, the center of gravity will be too high, which is prone to safety accidents. Even if the top plate 6 is pulled up and lifted, it is difficult to install materials such as long clamps and struts between the top plate 6 and the bottom plate 1. By separating the inner plate 602 from the outer frame 601, the inner plate 602 can be removed from the outer frame 601. At this time, space can be freed above the bottom plate 1, which is convenient for the transport trolley to adapt to the transfer of long clamps, struts and other materials. At the same time, the overall center of gravity of the transport trolley during transportation can be lowered, thereby improving the transportation safety of the trolley. The outer frame 601 can limit the material to a certain extent to avoid the material from tipping over during transportation, thereby further improving the safety during transportation.

[0031] In order to further improve the transportation stability of the conveyor trolley for small materials such as black film and rubber jump on the basis that the inner plate 602 can be removed, baffles 15 are vertically installed on all four sides of the bottom plate 1. A storage groove 16 is opened at the upper end of the baffle 15, and a sliding plate 17 is slidably installed inside the storage groove 16. The sliding plate 17 is fixedly connected to the pillar 5 and moves up and down with the pillar 5. The sliding plate 17 moves up and down with the pillar 5, so that the sliding plate 17 and the baffle 15 can rise with the rise of the pillar 5, allowing the conveyor trolley to transfer more small materials while preventing small materials from falling during transportation, improving the stability of the conveyor trolley when conveying materials and improving the efficiency of the conveyor trolley in conveying small materials at one time.

[0032] Furthermore, in order to improve the applicability of the conveying trolley to plate materials and to improve the convenience of unloading small materials, the baffles 15 on the two sides not opposite to the push handle 3 are rotatably connected to the base, and the tops of the sliding plates 17 on the two sides not opposite to the push handle 3 are provided with connecting rings 18, and the bottom of the top plate 6 is fixed with a fixing ring 19 corresponding to the connecting ring 18, and the connecting ring 18 and the fixing ring 19 are detachably connected by a pin. When conveying longer plate parts, the pin between the connecting ring 18 and the fixing ring 19 can be removed first, and then the baffles 15 on both sides can be rotated to lower the baffles 15, and then the plate parts can be placed between the top plate 6 and the bottom plate 1 from both sides of the conveying trolley. When transporting small materials, the connection between the connecting ring 18 and the fixing ring 19 is maintained during the conveying process. When loading, the inner plate 602 of the top plate 6 is removed and loaded from the top. When unloading, the pin shaft between the connecting ring 18 and the fixing ring 19 can be removed and unloaded from both sides of the conveying trolley, which improves the convenience of unloading and thereby improves the efficiency of coating production.
