The following describes the key design of the roll-over stand assembly:

The bottom of the front side beam 1 is fixedly connected with a front supporting leg 6, the bottom of the front supporting leg 6 is connected with a lower supporting rod 7, and the front supporting leg 6 and the lower supporting rod 7 form an L-shaped structure; one end of the lower stay bar 7 extends out of the rectangular frame to form a protruding structure.

The bottom of the rear side beam 2 is fixedly connected with a rear support 8 which is matched with the front supporting leg 6 in height; the heights of the rear support 8 and the front support 6 are adapted, as shown in fig. 3, and the front support 6 and the rear support 8 are supported on the ground to perform the function of supporting and heightening.

The top of the rear side beam 2 is connected with a rear vertical rod 9, the rear vertical rod 9 is fixedly connected with an upper supporting rod 10, and the rear vertical rod 9 and the upper supporting rod 10 form an L-shaped structure; one end of the upper stay bar 10 extends out of the rectangular frame, and also forms a protruding structure. When the rectangular frame is turned over, the upper stay 10 is supported on the ground, and the rear support 8 and the front leg 6 are inverted upward and no longer contact the ground, forming the pattern of fig. 4.

The force application assembly comprises a rocker arm 13, the outer wall of the side beam 3 is fixedly connected with a shaft rod 121, and one end of the rocker arm 13 is rotationally connected with the shaft rod 121; the other end of the rocker arm 13 is connected with an operating rod 14; the rocker arms 13 on two sides are connected into a whole by the operating rod 14 to form a U-shaped pattern, so that the function of drawknot fixation is achieved, and meanwhile, the force application of workers is facilitated.

In this embodiment, the rocker arm 13 can be engaged with the lower stay 7 or the upper stay 10, respectively, for driving the rectangular frame to turn over (forward or reverse).

Taking the state of the device in fig. 3 as an example, the rocker arm 13 is pressed down, the rocker arm 13 further presses down the upper supporting rod 10, and the device rotates around the rear support 8 as a base point at this time, so that reset is realized.

Taking the state of the device in fig. 4 as an example, when the operation starts during demolding, the upper supporting rod 10 is grounded at the moment, the device is dragged, the convex edge A11 of the die A1 enters the clamping groove 5, then the rocker arm 13 is lifted, the rocker arm 13 can lift the lower supporting rod 7, the device rotates by taking the upper supporting rod 10 as a base point, the overturning of the die A1 is completed, and the demolding is finally completed.

In order to facilitate the operation of workers, a more reasonable structural design is adopted: the rocker arm 13 is designed into a structure form of a small arm and a large arm, the small arm and the large arm are fixedly connected, an included angle is formed between the small arm and the large arm, and therefore, the operation of workers can be facilitated whether the small arm is lifted or pressed down; in this embodiment, the length of the small arm is smaller than that of the large arm, one end of the small arm is rotatably connected with the shaft 121, and the connection part of the small arm and the large arm can be used as a contact point with the lower stay 7.

The rotatable connection between the rocker arm 13 and the shaft 121 may be of the following simple structure:

One end of the forearm is fixedly connected with a sliding sleeve, one end of the shaft rod 121 can freely penetrate through the sliding sleeve, and the sliding sleeve and the shaft rod 121 are subjected to dry grinding. The sliding sleeve can be manufactured by processing waste steel pipes in the construction site, and the materials are easy to obtain.

It can be seen that, by arranging the lower stay bar 7 and the upper stay bar 10 at the front and rear positions respectively, when the rocker is matched with the lower stay bar 7, the die A1 can be overturned to finish demoulding action; after demolding is completed, the rocker is matched with the upper supporting rod 10, and reset centering of the rectangular frame is realized by pressing the upper supporting rod 10 down so as to perform next demolding; through adopting foretell structural design, the workman only need control the rocker and can realize upset and reset, need not to make a round trip to run again and carry out auxiliary reset, but serialization operation, labour saving and time saving improves work efficiency.

Example two

As shown in fig. 7, in the first embodiment, the rocker arm 13 is provided with a through hole 133, and the through hole 133 is connected with a collar 134 that can be engaged with the upper stay 10, and the collar 134 can be engaged with or disengaged from the upper stay 10.

In this embodiment, the loop 134 is one of a rope, an iron wire or a cable, preferably a cable or an iron wire, and a length of iron wire is threaded into the through hole 133, and two ends of the iron wire are lapped and screwed with pliers to form a ring shape. When the vibration is needed to be assisted manually, the ring sleeve 134 is hung with the upper supporting rod 10, and then the rocker arm 13 is lifted up and dropped down repeatedly, so that the vibration of the prefabricated trench cover plate B1 can be realized, and the rapid separation of the prefabricated trench cover plate B1 from the die A1 can be facilitated; when the iron wire is not used, the iron wire can be broken to a place which is not in the way, for example, the iron wire is stuck on the outer wall of the rocker arm 13, and the requirement can be completely met due to the bending property of the iron wire, so that the position can be conveniently adjusted.

When one end of the lower stay bar 7 needs to be tilted, the rocker arm 13 is pressed down to realize the shock; when the end of the rear support 8 needs to be tilted, the rocker arm 13 is lifted to realize the shock by hanging the annular sleeve 134.

Example III

On the basis of the first embodiment or the second embodiment, the method is a better design: the arc-shaped overturning plate 11 is fixedly connected to the rear edge beam 2, and can play an auxiliary role in overturning. In the overturning process, the arc-shaped surface 111 of the arc-shaped overturning plate 11 is in contact with the ground, and the force required for overturning the die A1 can be effectively reduced due to the arc shape.

Working principle:

When in use, the operation rod 14 is dragged to drive the device to move, so that the convex edge A11 of the die A1 enters the clamping groove 5; then the operating rod 14 is lifted, the operating rod 14 drives the rocker arm 13 to act, the rocker arm 13 abuts against the lower supporting rod 7 and drives the lower supporting rod 7 to turn over, and the rectangular frame and the die A1 are turned over together; the mould A1 is buckled on the ground, and in the process of floor vibration, the prefabricated trench cover plate B1 is separated from the inner wall of the mould A1, so that demoulding is completed; then the die A1 is pulled out of the clamping groove 5 and moved to a designated position; then, the operating rod 14 is pressed down, the operating rod 14 is pressed on the upper supporting rod, the rectangular frame is driven to reversely overturn until reset, and the preparation is made for the next demoulding.

It should be noted that, if the mold A1 is turned over and the prefabricated trench cover B1 is not separated from the mold A1, at this time, a manual auxiliary vibration mode may be adopted, for example, the loop 134 is hung on the upper stay 10, the rocker 13 is lifted up and then falls down, so that the rectangular frame vibrates up and down, and the separation of the mold A1 and the prefabricated trench cover B1 can be effectively realized.

While embodiments of the present utility model have been shown and described, it will be understood by those of ordinary skill in the art that: many changes, modifications, substitutions and variations may be made to the embodiments without departing from the spirit and principles of the utility model, the scope of which is defined by the claims and their equivalents.
