Description

Technical Field

[0001] This utility model relates to a robotic arm paving device for a cement paver. Background Technology

[0002] The demand for airport construction and renovation in my country is constantly increasing. The most crucial step in the construction of airport concrete runways is concrete paving. Traditional airport concrete runway paving requires a large amount of manual labor for leveling, consuming significant manpower and being inefficient. Therefore, robotic arms are needed to replace manual labor and ensure the smoothness of the paved surface. Currently, the connection structure between the robotic arm and the mobile platform of cement pavers cannot meet the force requirements of the robotic arm during concrete paving, nor can it guarantee stable back-and-forth movement. Specifically, during the back-and-forth movement of the robotic arm while paving concrete, insufficient support at the connection point between the robotic arm and the mobile platform causes the robotic arm to sway.

[0003] Based on this, in order to solve the above technical problems, this case proposes a robotic arm paving device for a cement paver. Utility Model Content

[0023] like Figures 1-3 As shown, this embodiment provides a robotic arm paving device for a cement paver, including a robotic arm 1. The execution end of the robotic arm is connected to a paving plate 2, and the base end of the robotic arm is connected to a crossbeam 4 via a slider-rail sliding pair 3. The number of slider-rail sliding pairs is at least two sets and they are distributed vertically. The sliding plane of the upper slider-rail sliding pair is a horizontal plane, and the sliding plane of the lower slider-rail sliding pair is a vertical plane.

[0024] By setting at least two sets of slider-rail sliding pairs, and making the sliding plane of the upper slider-rail sliding pair a horizontal plane and the sliding plane of the lower slider-rail sliding pair a vertical plane, the robot can obtain corresponding translational guidance support in both the horizontal and vertical planes, thereby improving the translational support stability of the robot and preventing the robot from swaying during paving.

[0025] In this embodiment of the invention, the plank is screwed and locked to the execution end of the robotic arm.

[0026] In this embodiment of the invention, the base of the robotic arm is connected to the slider rail moving pair via an adapter plate.

[0027] In this embodiment of the utility model, the adapter plate is composed of a horizontal plate 5 and a vertical plate 6. The horizontal plate is locked to the top of the vertical plate by screws, and the mounting holes on the horizontal plate for passing screws are longitudinally extending groove holes 7.

[0028] The longitudinally extending groove holes allow for longitudinal movement and adjustment when connecting the horizontal and vertical plates, reducing positioning difficulty, making installation more convenient, and also solving the problem of manufacturing errors between the horizontal and vertical plates.

[0029] In this embodiment of the utility model, the horizontal plate is screwed to the slider of the upper slider slide rail moving pair by screws.

[0030] In this embodiment of the utility model, the vertical plate is screwed to the slider of the slider slide rail moving pair below by screws, wherein the mounting hole on the vertical plate for passing the screw is a vertical extension groove hole 8.

[0031] The vertically extending groove holes allow for vertical movement and adjustment when the vertical plate is connected to the corresponding slider, reducing positioning difficulty and making installation more convenient.

[0032] In this embodiment of the utility model, the base end of the robot is fixedly connected to a vertical plate, and a bottom plate 9 for supporting the base end of the robot is vertically fixed at the bottom end of the vertical plate.

[0033] In this embodiment of the invention, a power drive assembly is provided between the base end of the robotic arm and the crossbeam.

[0034] In this embodiment of the utility model, a power drive assembly is provided between the base end of the robot and the crossbeam. The power drive assembly includes a motor 10 fixedly connected to a vertical plate. The output shaft of the motor extends longitudinally and is coaxially fixedly connected to a gear 11. The gear meshes with a transversely extending rack 12 fixedly connected to the crossbeam.

[0035] In this embodiment of the invention, the gear is a helical gear.

[0036] Helical gears have a stronger load-bearing capacity than spur gears, provide smoother transmission, and effectively reduce vibration and noise. This indirectly ensures that the robotic arm can move stably to smooth the concrete, guaranteeing that the smoothed surface meets the requirements.

[0037] In this embodiment of the invention, a bellows cover 13 is connected between the adapter plate and the crossbeam for dust prevention. The structure and installation of the bellows cover are prior art and will not be described in detail here.

[0038] In this embodiment of the invention, the working principle of the robotic arm paving device of the cement paver is as follows:

[0039] When the motor rotates, the meshing of the gears and racks drives the robotic arm to move back and forth laterally, controlling the paving plate to smooth the concrete. The robotic arm paving device of this cement paver uses at least two sets of slider-rail sliding pairs, with the upper pair having a horizontal sliding plane and the lower pair having a vertical sliding plane. This ensures the robotic arm receives corresponding translational guidance and support in both the horizontal and vertical planes, improving its translational stability and preventing swaying during paving.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
