[0028] The utility model will be further described in detail below in combination with embodiments.

[0029] The specific embodiment of the utility model provides a movable concrete troweling machine:

[0030] Please refer to Figures 1-6 , the movable concrete troweling machine, including protection frame 10, main frame 11, handrail 12, main shaft 13, engine 14, troweling disc 15 and walking structure.

[0031] Engine 14 is installed on the upside of main frame 11, main shaft 13 is installed on the downside of main frame 11, and the lower end of main shaft 13 is connected with troweling disc 15.

[0032] Engine 14 drives main shaft 13 and troweling disc 15 to rotate through transmission structure, and troweling disc 15 rotation realizes concrete surface collection.

[0033] Protection frame 10 is inverted conical net-like structure and is connected on the downside of main frame 11. Protection frame 10 is higher than troweling disc 15 and forms safety protection to troweling disc 15.

[0034] The rear side of main frame 11 is connected with inclined handrail 12.

[0035] Walking structure includes U-shaped reinforcing frame 1, steel pipe 2, movable reinforcing frame 3 and walking wheel 4.

[0036] Both end portions of U-shaped reinforcing frame 1 are connected with the rear side of the protection frame 10 of troweling machine, and steel pipe 2 is rotatably sleeved on the outside of the middle portion of U-shaped reinforcing frame 1.

[0037] Movable reinforcing frame 3 is connected on the outside of steel pipe 2, and walking wheel 4 is rubber wheel, and walking wheel 4 is installed on the end of movable reinforcing frame 3 away from steel pipe 2.

[0038] The movable reinforcing frame 3 comprises two L-shaped reinforcing bars 301 connected with the steel pipe 2, and the two L-shaped reinforcing bars 301 are pivotally installed on the above-mentioned traveling wheels 4 away from the end of the steel pipe 2.

[0039] The first reinforcing bar 302 and the second reinforcing bar 303 are connected between the two L-shaped reinforcing bars 301, the first reinforcing bar 302 and the second reinforcing bar 303 are parallel, and the first reinforcing bar 302 is closer to the traveling wheel 4 than the second reinforcing bar 303.

[0040] The side wall of the steel pipe 2 is slidably provided with the positioning plate 5, and the side wall of the steel pipe 2 is provided with a strip-shaped hole for the positioning plate 5 to slide through. The outer side of the middle part of the U-shaped reinforcing frame 1 is provided with two positioning grooves 6 above and below which cooperate with the positioning plate 5.

[0041] When the positioning plate 5 extends into the two positioning grooves 6 and cooperates with the two positioning grooves 6, the movable reinforcing frame 3 is located on the upper side and the lower side of the U-shaped reinforcing frame 1 respectively. When the positioning plate 5 extends into the positioning groove 6, the steel pipe 2 and the movable reinforcing frame 3 cannot rotate around the middle part of the U-shaped reinforcing frame 1.

[0042] The pull rod 7 is linearly slidably arranged on the movable reinforcing frame 3, one end of the pull rod 7 is connected with the positioning plate 5, and the other end of the pull rod 7 is connected with the pull ring 9.

[0043] Specifically, the pull rod 7 slides through the middle part of the second reinforcing bar 303, and the middle part of the second reinforcing bar 303 is provided with a through hole for the pull rod 7 to slide through. The pull ring 9 is located between the first reinforcing bar 302 and the second reinforcing bar 303.

[0044] The spring 8 is connected between the movable reinforcing frame 3 and the positioning plate 5, and the spring 8 is sleeved outside the pull rod 7; the spring 8 moves the positioning plate 5 towards the inside of the steel pipe 2, i.e. towards the middle part of the U-shaped reinforcing frame 1, so that the positioning plate 5 can enter the positioning groove 6 when not subjected to external force.

[0045] The positioning plate 5 is pulled by the pull ring 9 to pull the pull rod 7 and the positioning plate 5, so that the positioning plate 5 compresses the spring 8 and separates from the positioning groove 6, and the steel pipe 2 and the movable reinforcing frame 3 can rotate around the middle part of the U-shaped reinforcing frame 1.

[0046] When the troweling machine is in working state, the positioning plate 5 extends into the positioning groove 6 on the upper side of the middle part of the U-shaped reinforcing frame 1, so that the movable reinforcing frame 3 and the traveling wheel 4 are stably arranged on the upper side of the U-shaped reinforcing frame 1, and do not affect the troweling disc 15 to adhere to the surface of the concrete for finishing.

[0047] When the trowel needs to be moved, the pull ring 9 is pulled, the positioning plate 5 compresses the spring 8 to slide outwards from the steel pipe 2, the positioning plate 5 is separated from the positioning groove 6 on the upper side, the movable steel bar frame 3 is rotated and the pull ring 9 is loosened, when the positioning plate 5 corresponds to the positioning groove 6 on the lower side of the middle part of the U-shaped steel bar frame 1, the spring 8 makes the positioning plate 5 extend into the positioning groove 6 on the lower side, the rotation of the movable steel bar frame 3 and the steel pipe 2 is limited, at this time, the movable steel bar frame 3 and the walking wheel 4 are located on the lower side, the handrail 12 is pressed downwards, and the trowel can be pushed to walk.

[0048] Finally, it should be noted that the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing detailed description of the present application is made with reference to the foregoing embodiments, for those skilled in the art, it still can be modified without the need to pay the creative labor of the technical solutions recorded in the foregoing embodiments, or for equivalent replacement of some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
