Description
Technical Field
[0001] This utility model relates to the field of road roller cover technology, and in particular to a single-cylinder support structure for preventing tilting of a road roller cover. Background Technology
[0002] Currently, the common structure for supporting the machine cover of road rollers on the market uses hydraulic cylinders on both sides, preventing the cover from tilting. For example... Figure 1 As shown, the dual-cylinder supported engine cover structure consists of a manual pump 1, a pump-to-cylinder hose 2, a hydraulic oil tank 3, a cylinder 4, a cylinder pin weld 5, a hinge 6, a fixing pin 7, a cylinder interconnection hose 8, a cylinder 9, and an engine cover 10. The manual pump 1 adjusts the vertical movement of cylinders 4 and 9 to raise and lower the engine cover 10. Because when the engine cover 10 is open, the engine air filter is at the same horizontal position as cylinders 4 and 9, it cannot be disassembled for cleaning. Therefore, a single-cylinder support mechanism for the engine cover 10 is designed to ensure that the engine air filter is not interfered with by any cylinder on one side, facilitating disassembly and cleaning. Utility Model Content
[0003] The technical problem solved by this invention is that the engine air filter of a road roller with a double-cylinder supported hood structure cannot be disassembled for cleaning.
[0004] To solve the above-mentioned technical problems, this utility model provides a single-cylinder support structure for the anti-tilting of a road roller's hood, comprising:

[0006] The hydraulic cylinder connector is connected to the movable slots of the corresponding ear plates near its two ends, and has a connecting end at one end.
[0007] The hydraulic cylinder is connected to one side of the machine body, and its two ends are movably connected to the machine body and the connecting end, respectively.
[0008] When the cylinder extends, the connecting end drives the cylinder connector to slide in the movable slot, which in turn drives the machine cover to open through the machine cover reinforcing plate.
[0009] Optionally, the cylinder connector includes:
[0010] Connecting shaft;
[0011] A pair of left slot plates are connected to the connecting shaft near the left end, and the pair of left slot plates and the connecting shaft define a left connecting slot;

[0014] A pair of bearings are respectively connected to the left end of the connecting shaft and the right end between the pair of connecting plates; wherein
[0015] The left connecting groove and the right connecting groove are respectively connected to the corresponding movable slot holes. When the oil cylinder extends, it drives the connecting shaft to slide in the movable slot hole through the connecting end, thereby transmitting the force to the machine cover through the machine cover reinforcing plate and causing the machine cover to open.
[0016] Optionally, when the connecting shaft is connected to the ear plate, the bearing contacts the surface of the housing reinforcement plate.
[0017] Optionally, the hydraulic cylinder is rotatably connected to the connecting plate via a cylinder pin.

When the cylinder 14 extends, the connecting end 941 drives the cylinder connector 19 to slide in the movable slot 211, thereby causing the hood 18 to open via the hood reinforcing plate 20.
[0037] Optionally, such as Figure 3As shown, the hydraulic cylinder connector 19 includes a connecting shaft 91; a pair of left groove plates 92 connected to the connecting shaft 91 near the left end, with the pair of left groove plates 92 defining a left connecting groove 921 with the connecting shaft 91; a pair of connecting plates 94 connected to the right end of the connecting shaft 91, with the pair of connecting plates 94 defining a connecting end 941 with the connecting shaft 91; a right groove plate 93 connected to the connecting shaft 91 and near the left side of the connecting plate 94, with the right groove plate 93 and the connecting plate 94 defining a right connecting groove 931 with the connecting shaft 91; and a pair of bearings 95, respectively connected to the left end of the connecting shaft 91 and the right end between the pair of connecting plates 94; wherein the left connecting groove 921 and the right connecting groove 931 are respectively connected to the corresponding movable slots 211. When the hydraulic cylinder 14 extends, the connecting shaft 91 is driven to slide in the movable slots 211 through the connecting end 941, thereby transmitting the force to the machine cover 18 through the machine cover reinforcing plate 20, causing the machine cover 18 to open.
[0038] Optionally, when the connecting shaft 91 is connected to the ear plate 21, the bearing 95 contacts the surface of the machine cover reinforcing plate 20.
[0039] Optionally, the hydraulic cylinder 14 is rotatably connected to the connecting plate 94 via the hydraulic cylinder pin 15.

[0041] Optionally, the diameter of the connecting shaft 91 is smaller than the diameter of the movable slot 211, which is an elongated slot.
[0042] Optionally, the hood reinforcement plate 20 has a notch 22 located between the two ear plates 21.

[0045] Optionally, it also includes a manual pump 11, which is connected to the cylinder 14 via a cylinder hose 12.
[0046] The following description will further illustrate the characteristics and functions of this utility model.
[0047] The single-cylinder engine cover anti-tilt structure in this embodiment is mainly designed to solve the problem that the engine air filter cannot be removed when the engine cover is supported by a double-cylinder engine cover. Therefore, a single-cylinder engine cover anti-tilt structure is designed so that the engine air filter can be removed from the side without cylinder interference, which is convenient for cleaning.
[0048] The single-cylinder support structure for preventing tilting of the machine hood in this embodiment mainly achieves its function through a single-sided hydraulic cylinder 14, a hydraulic cylinder connector 19, and a machine hood reinforcing plate 20 installed on the machine body. The machine hood reinforcing plate 20 is connected to the machine hood 18, the hydraulic cylinder connector 19 is connected to the machine hood reinforcing plate 20, and the hydraulic cylinder 14 is connected to the connecting end 941 of the hydraulic cylinder connector 19.
[0049] The connecting shaft 91 of the cylinder connector 19 passes through the movable slot 211 of the lug 21 of the engine hood reinforcing plate 20, allowing the connecting shaft 91 to slide within the movable slot 211. When the cylinder 14 extends, it drives the connecting end 941 of the cylinder connector 19 to generate an upward and forward driving force. The connecting end 941 transmits the force to the connecting shaft 91, which slides within the movable slot 211 and transmits the force to the engine hood reinforcing plate 20. Finally, the engine hood reinforcing plate 20 transmits the force to the engine hood 18, opening the engine hood 18. During the opening process, due to the reinforcing effect of the engine hood reinforcing plate 20, the engine hood 18 will not tilt to the side without the cylinder, but will open very smoothly. The operator can then remove and clean the engine air filter from the side without the cylinder.
[0050] In summary, the single-cylinder support anti-tilt structure of this utility model connects the cylinder connector and the hood reinforcement plate between the single-sided cylinder and the hood, so that when the single-sided cylinder extends, the hood can still be opened without tilting through the cylinder connector and the hood reinforcement plate. The single-cylinder support anti-tilt structure of this utility model has a novel structure, is easy to install and connect, has smooth transmission, no impact, large load transmission, and high operational reliability.
[0051] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
