Description

Technical Field

[0001] The invention relates to the technical field of coal mine concrete pavement finishing, in particular to a concrete pavement construction finishing machine. Background Art

[0002] A plastering machine is a mechanical device used for preliminary surface treatment of concrete pavements. The working principle of the plastering machine is to use an engine to drive the grinding disc to rotate. The grinding disc rotates at a relatively low speed to push and flatten the material on the surface of the concrete, eliminate potholes and bumps on the surface of the concrete pavement after pouring, and perform preliminary leveling and plastering operations on the concrete surface. In coal mining areas, in order to facilitate the driving of coal transport vehicles, it is necessary to build a concrete pavement, and the use of a plastering machine can be used for the preliminary shaping of the concrete pavement.

[0003] The existing trowels used for concrete pavement treatment are usually hand-held or ride-on types, both of which are used for horizontal pavement treatment. However, for the inclined slope protection sections on both sides of the road, the ride-on trowels with people on board are prone to overturning during inclined work, and it consumes too much energy to travel up and down along the inclined road surface. Therefore, it can only be treated by hand-held trowels. However, due to the inclination of the road surface, multiple people are required to pull and push the trowel up and down at the same time. Compared with horizontal road surface treatment, there are problems of labor consumption and cumbersome operation. There is a lack of a universal trowel that can be easily used on both horizontal and inclined roads. Summary of the invention

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This coal mine concrete pavement construction plastering machine is equipped with a traction mechanism. The traction ropes on the two rope rollers are connected to the hollow protective frame to pull the plastering mechanism. The two roller frames are driven away from each other by two rodless cylinders. The roller frames drive the two rope rollers to move away from each other, so that the two traction ropes and the hollow protective frame form a triangular area. In the process of the wheel rotation driving the frame to move, the traction rope pulls the plastering mechanism to move and automatically plaster the inclined road surface.

[0016] 2. This coal mine concrete pavement construction plastering machine is equipped with a rotating ring and a bearing. After the plastering treatment of the inclined road surface is completed, the plastering mechanism is picked up and installed on the connecting frame with the help of a fixed shaft. The gear is driven to rotate by a rotating motor, and the gear drives the rotating ring to rotate through the rack. The rotating ring rotates relative to the center column through the bearing, and drives the plastering mechanism from one side of the frame to the back side of the frame through the connecting mechanism, so that the plastering mechanism is used for horizontal road surface plastering treatment at the back side of the frame. The position of the plastering mechanism can be adjusted by rotating the rotating ring, and the working state of the plastering mechanism is switched for horizontal and inclined roads, so as to achieve a common effect for horizontal and inclined roads.

[0017] 3. This coal mine concrete pavement construction finishing machine is equipped with a connecting mechanism and a hanging mechanism. When concrete adheres to the bottom of the grinding disc or the grinding disc needs maintenance, the telescopic cylinder contracts to apply tension to the connecting frame through the fixed ring, so that the connecting frame rotates upward around the first pin axis, and the connecting frame drives the finishing mechanism to move upward through the fixed axis, and hooks the hook on the rear side wall of the hollow protective frame. The hollow protective frame is pulled by the hanging rope to flip upward relative to the connecting frame with the fixed axis as the axis. The hollow protective frame drives the grinding disc to flip from a horizontal state to a vertical state, so that the concrete on the surface of the grinding disc can be cleaned from the back side and the grinding disc can be maintained.

[0018] 4. The coal mine concrete pavement construction plastering machine is provided with a fixed shaft, a curved groove and a pressure block. The fixed shaft is detachably connected to the connecting frame by plugging into the curved groove, so that the plastering mechanism can be connected to the connecting frame for use when processing horizontal pavement, and can be removed for traction when processing inclined pavement. After the fixed shaft is inserted into the curved groove, the screw is driven to rotate by the knob, and the screw rotates and moves downward through the screw hole, and pushes the pressure block to move downward to squeeze the fixed shaft. The pressure block limits the fixed shaft from falling off from the curved groove, thereby enhancing the stability of the connection between the fixed shaft and the connecting frame.
