DETAILED DESCRIPTION
[0021] To make the person skilled in the art more clear and definite the technical scheme of the utility model, the utility model is described in further detail below in conjunction with examples and drawings, but the implementation mode of the utility model is not limited to this.
[0022] As Figs. 1-3As shown, the concrete stripping auxiliary device provided by the embodiment comprises a stripping frame body 1 and a mold body 2, the stripping frame body 1 is provided with four groups of turnover legs 102 on the periphery, a fixed frame 101 is welded and fixed in the inner wall of the turnover leg 102, a rotating shaft sleeve 104 is welded on the top of both sides of the fixed frame 101, a rotating shaft rod 105 is welded in the rotating shaft sleeve 104, a handrail rod 106 is rotatably nested at the outer end of the rotating shaft rod 105, and a knocking mechanism 3 is arranged on the handrail rod 106.
[0023] In the above structure, the hammer head 305 always keeps a drooping state, when the concrete structure exists in the mold body 2, the bottom of the hammer head 305 is in contact with the top of the concrete test block, and when not, the hammer head 305 is in the internal cavity of the fixed frame 101; a limiting bearing is arranged in the rotating ring 301, which can keep the rotating ring 301 to rotate at the center of the handrail rod 106.
[0024] The pulley 103 is rotatably installed in the bottom inner cavity of the turnover leg 102, which facilitates the stripping frame body 1 to slide into the limiting groove 101a of the mold body 2, improves the moving flexibility of the device, the limiting groove 101a is formed in the inner wall of the fixed frame 101, the limiting groove 101a is aligned and clamped with the frame wall edge of the mold body 2, and plays a role of turnover support, the outer wall of two groups of turnover legs 102 is fixed with an arc-shaped plate 102a on one side, the arc-shaped plate 102a plays a role of buffering and force when the front turnover leg 102 is turned over, and the outer wall of the other two groups of turnover legs 102 is welded with a limiting rod 107 on one side, the limiting rod 107 lifts the turnover leg 102, the fixed frame 101 and the mold body 2 when the handrail rod 106 is raised.
[0025] The bottom of the limiting rod 107 is in sliding contact with the outer wall of the handrail rod 106, and the mold body 2 is in sliding connection with the limiting groove 101a.
[0026] The hammer head 305 and the inner wall of the U-shaped frame 304 are rotatably installed through the penetrating shaft pin, the spring 306 is clamped and pressed between the top outer wall of the hammer head 305 and the inner wall of the U-shaped frame 304, the spring 306 can not only guarantee that the hammer head 305 is in movable contact with the turnover fixed frame 101, but also can be restored to the vertical position, which is convenient for knocking the bottom of the mold body 2 in the posture of vertical falling.
[0027] The power grip 302 is welded and fixed at the bottom of the rotating ring 301, the power grip 302 rotates synchronously with the rotating ring 301 and the connecting rod 303, the length is set to 30-40 cm, which does not affect the turnover of the fixed frame 101, and is convenient for the user to operate.
[0028] The hammerhead 305 is a solid rubber structure to prevent the metal structure from damaging the mold body 2.
[0029] The working principle of this device is as follows:
[0030] When in use, the demolding frame body 1, carrying the internally shaped precast concrete components, is neatly arranged on the ground. The user pushes the demolding frame body 1 to one side of the mold body 2 via the pulley 103. It is then inserted into the frame of the mold body 2 through the limiting groove 101a until the mold body 2 is completely inside the fixed frame 101. The user then flips up the handrail 106, and one end of the handrail 106 rotates along the rotating shaft 105. The middle part is abutted by the limiting rod 107, which lifts the fixed frame 101 together with the mold body 2. The fixed frame 101 flips along the rotating shaft sleeve 104. After being buffered by the arc plate 102a, it flips 180°, thus turning the mold body 2 upside down. Under the action of gravity, the internally shaped precast concrete components detach from the mold body 2.
[0031] During the flipping process, the hammer head 305 remains in contact with the top of the mold body 2 and is pushed upward through sliding action. At this time, the connecting rod 303 rotates on the handrail 106 through the rotating ring until the hammer head 305 passes the fixed frame 101 and then falls back to the bottom center position of the mold body 2. For concrete precast parts that have not been separated from the mold body 2, the user can push them forward through the power handle 302. At this time, the connecting rod 303 rises to a certain height and then falls freely to strike the bottom center of the mold body 2, providing appropriate vibration force to shake the internal concrete off.
[0032] By adopting the above structure, the work required by the user to handle unseparated concrete parts by multiple vibrations during the demolding process can be reduced, thereby reducing the damage rate of concrete parts and reducing physical labor consumption.
[0033] The above are merely further embodiments of this utility model, but the protection scope of this utility model is not limited thereto.
