Background
Concrete is a general term for engineering composite materials in which aggregate is cemented into a whole by a cementing material. The term concrete generally refers to cement as the cementing material and sand and stone as the aggregate; the cement concrete, also called as common concrete, is obtained by mixing with water (which may contain additives and admixtures) according to a certain proportion and stirring, and is widely applied to civil engineering.
Because the bridge floor has certain radian, most of the existing concrete flattening devices do not have the function of adjusting the radian, and therefore, the existing concrete flattening devices are not suitable for being used on the bridge floor. And the bridge deck is mainly flattened manually, so that the consistency of the flattening thickness cannot be ensured, and the problem of low operation efficiency also exists.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems in the background art, the utility model provides a bridge deck concrete spreading device.
The utility model adopts the following technical scheme: a bridge deck concrete flattening device comprises a cross column, a rotating shaft, a roller, a scraper, two spring frames, two fixing frames, two upper supporting frames, two lower supporting frames and two pneumatic cylinders;
two fixing frames are symmetrically fixed at the upper end of the transverse column, two ends of the rotating shaft are respectively rotatably connected with the two fixing frames, one end of each upper supporting frame is symmetrically fixed on the rotating shaft, the other end of each upper supporting frame is respectively hinged with one end of the corresponding lower supporting frame, the other ends of the two lower supporting frames are fixedly connected with the scraper, two spring frames are fixed on the side wall of the front end of the transverse column, the two spring frames are in one-to-one correspondence with the two upper supporting frames and are respectively attached and connected,
the lower extreme symmetry of spreader is fixed with two pneumatic cylinders, and the cylinder pole of two pneumatic cylinders all sets up down, and the shaft at gyro wheel both ends rotates with the lower extreme of the cylinder pole of two pneumatic cylinders to be connected.
Furthermore, a connecting device is arranged on the side wall of the rear end of the transverse column, an air cylinder is fixed at the lower end of the connecting device, and a cylinder rod of the air cylinder is arranged downwards and is fixedly connected with the base.
Furthermore, the hinged parts of the two upper support frames and the two lower support frames are provided with limit blocks.
Compared with the prior art, the utility model has the beneficial effects that: make through lift pneumatic cylinder and connecting device and form the angle between upper bracket and the lower support frame, make the bridge floor of laminating always of scraper blade then, make the concrete shakeout even, guarantee construction quality.

FIG. 1 is a schematic view of the overall structure of the present invention;
FIG. 2 is a right side view of the present invention;
FIG. 3 is a connection structure diagram of a limiting block, an upper support frame and a lower support frame of the utility model;
in the figure: 1 horizontal column, 2 fixed frames, 3 rotating shafts, 4 upper supporting frames, 5 lower supporting frames, 6 connecting devices, 7 spring frames, 8 pneumatic cylinders, 9 rollers, 10 scraping plates and 11 limiting blocks.
Detailed Description
The technical solutions in the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, rather than all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without any creative work based on the embodiments of the present invention belong to the protection scope of the present invention.
As shown in fig. 1 to 3, the present embodiment describes a bridge deck concrete flattening device, which includes a horizontal column 1, a rotating shaft 3, a roller 9, a scraper 10, two spring brackets 7, two fixing brackets 2, two upper support frames 4, two lower support frames 5, and two pneumatic cylinders 8;
