Description

Technical Field

[0001] This utility model relates to a control mechanism for a road roller, belonging to the technical field of control systems for engineering machinery. Background Technology

[0002] Currently, most road rollers on the market, especially small road rollers used in narrow spaces such as sidewalks, green belts, and road repairs, typically have their control handles located on only one side of the cab. This single-side arrangement can meet the needs of conventional straight-line compaction operations, but its inherent design flaws become apparent when performing edge compaction or curved operations, making it difficult to meet the requirements for ease of operation and visibility under complex working conditions.

[0003] Specifically, when it is necessary to compact the edge of the road, wall, or adjacent area of ​​an obstacle on the other side of the roller (i.e., the side away from the control handle), the operator must twist their body significantly and turn sideways to observe, resulting in an awkward operating posture and blind spots. This not only makes precise control of edge compaction difficult, easily causing missed compaction or uneven compaction, affecting construction quality, but also leads to rapid muscle fatigue in the operator due to prolonged unconventional posture, reducing work efficiency and potentially causing safety hazards due to poor visibility. Therefore, there is an urgent need for an operating mechanism solution that can fundamentally improve the above problems. Summary of the Invention

[0004] Purpose of the invention: To address the shortcomings of existing technologies, this invention provides an operating mechanism for road rollers, thereby solving the problems mentioned in the background section.

[0005] Technical solution: A control mechanism for a road roller, comprising a mounting base plate and an operating handle assembly mounted on a control panel, wherein the operating handle assembly includes a left operating handle and a right operating handle mounted on the left and right sides of the mounting base plate, and the left and right operating handles are linked by a rotating mechanism mounted on the underside of the mounting base plate.

[0006] This invention solves the technical problems of inconvenient operation, limited field of vision, and easy operator fatigue caused by traditional road rollers with only a single-sided control handle. By setting up a double handle that is symmetrical on both sides and linked by a rotating mechanism, the operator can flexibly choose the control side according to the construction position and obtain the best field of vision without changing posture. This significantly reduces operator fatigue and improves compaction accuracy and construction efficiency.

[0007] The mounting base plate is configured with a convex structure. The bottom edges of both sides of the mounting base plate are fixedly connected to the control panel. The rotating mechanism passes through both sides of the mounting base plate and is connected to the left and right operating handles respectively. At least two guide blocks with guide holes are fixedly connected to the lower side of the mounting base plate. The rotating mechanism passes through the guide holes and is rotatably connected to the guide blocks.

[0008] By setting the mounting base plate as a convex structure and symmetrically setting guide blocks with guide holes on its lower side, the technical problem of unstable operation caused by easy shaking and deviation of the rotating mechanism during operation is solved. This provides stable support and precise guidance for the rotating mechanism, achieving the technical effect of enhancing the overall structural rigidity and ensuring accurate and reliable transmission of operating actions.

[0009] It also includes a vertical mounting plate located in the middle of the lower side of the mounting base plate for mounting the flexible shaft. The upper side of the vertical mounting plate has a window that allows the rotating mechanism to pass through freely. A gear sensor is located on the upper side of the vertical mounting plate in front of the rotating mechanism.

[0010] By setting a vertical mounting plate in the middle of the lower side of the mounting base to regulate the path of the flexible shaft, and setting a gear position sensor in front of the rotating mechanism, the technical problems of easy interference between the cable and moving parts and inability to intuitively confirm the gear position are solved. This achieves the technical effects of avoiding interference, improving reliability, and enabling real-time monitoring and display of gear position to enhance operational safety.

[0011] The rotating mechanism includes a hollow linkage tube that runs through the left and right sides of the mounting base plate, a gear position blocking part mounted on the linkage tube and located on either side of the vertical mounting plate, and a reset spring mounted on the linkage tube between the gear position blocking part and the guide block. The two ends of the linkage tube are respectively connected to the left operating handle and the right operating handle.

[0012] By employing a hollow linkage tube, a gear position blocking part fitted onto it, and a reset spring located between the blocking part and the guide block to form a rotating mechanism, the technical problem of the control handle not being able to automatically return to its original position after operation, thus affecting the preparation state for the next operation, is solved. This achieves the technical effect of the handle being able to automatically and smoothly return to the preset position after operation, ensuring the continuity and safety of operation.

[0013] It also includes a locking component, which includes a connecting rod disposed inside the linkage tube. A long groove is provided at the connection between the linkage tube and the shielding part. A sliding rod is provided through the shielding part and the long groove to fix the position of the shielding part and to allow the shielding part to slide on the linkage tube along the direction of the long groove. One end of the connecting tube is fixedly connected to the left or right operating handle, and the other end is fixedly connected to the sliding rod. The shielding part is provided with a limit rod and a shielding rod, and the vertical mounting plate is provided with a limit part with a limit groove. When the gear is in P gear, the limit rod is embedded in the limit groove, and when in P gear, the shielding rod is located at the detection port of the gear sensor.

[0014] By setting a connecting rod and a sliding rod inside the linkage pipe, and setting a limit rod and a blocking rod on the shielding part, in conjunction with the limit groove and gear sensor on the vertical mounting plate, the technical problems of unreliable P gear locking, easy accidental disengagement, misoperation, and inaccurate gear signal triggering are solved. This achieves dual locking and confirmation by both mechanical and electrical means, providing a high level of safety assurance for equipment parking.

[0015] The left and right operating handles are equipped with the same function buttons.

[0016] By setting identical function buttons on both left and right control handles, the technical problems of confusing operation logic, high learning costs, and easy misoperation caused by the different functions of the two control handles are solved. A unified mirrored operation interface is created, which enables operators to seamlessly switch to use either control handle without having to adapt, thus improving the intuitiveness and efficiency of operation.

[0017] Beneficial effects: This utility model, by setting up symmetrical, rotating and linked dual handles, combined with a stable guide base, integrated wiring and sensor structure, automatic reset mechanism, reliable P-gear mechanical-electric dual locking device, and unified functional interface, fundamentally solves the problems of inconvenience, limited field of vision, and operator fatigue caused by single-sided operation in edge compaction. It significantly improves the convenience, comfort, and safety of operation. At the same time, the structural optimization improves the reliability of the system, enabling the road roller to carry out efficient, precise, and safe construction operations in confined spaces.
