Detailed Description
The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:
referring to fig. 1-2, a main drainage ditch box mold with a tunnel inverted arch capable of narrowing and demolding movement is composed of a box mold main body 1 and auxiliary moving mechanisms 2 symmetrically positioned at the front end and the rear end of the box mold main body 1.
The box die main body 1 is of a bilaterally symmetrical spliced box body structure.
The box die main body 1 is longitudinally welded with hydraulic cylinder mounting seats 11 at intervals.
The hydraulic cylinder mounting seats 11 are symmetrically provided with hydraulic cylinders 12 in the horizontal direction, and the ends of telescopic rod ends of the hydraulic cylinders 12 are fixed on the left side plate and the right side plate of the box die main body 1 at the same side.
When the telescopic rod synchronously contracts inwards, the transverse width of the box die main body 1 is narrowed and demoulded;
the front end plate of the box die main body 1 is provided with a counterweight water injection pipe 13, the rear end plate is provided with a drain pipe close to the bottom of the box die main body 1, and the counterweight water injection pipe 13 is higher than the drain pipe.
The width of the top surface of the box die main body 1 is larger than that of the bottom surface, and the width difference between the upper end surface and the lower end surface is 1 cm-2 cm.
The auxiliary moving mechanism 2 comprises a supporting seat 21 fixed on the front and rear walls of the box die main body 1 and telescopic legs 22 vertically corresponding to the supporting seat 21.
The supporting seat 21 is provided with a vertical through hole 211, a platform 212 for lifting a jack and a lifting hook 213 for lifting and hanging.
The side of the supporting seat 21 away from the box die main body 1 is provided with a platform 212.
The top surface of the supporting seat 21 is provided with a hanging hook 213.
The telescopic leg 22 is composed of an inverted "T" shaped supporting main frame 221 having a vertical section passing through the vertical through hole 211 and rollers 222 positioned at left and right ends of the horizontal section of the inverted "T" shaped supporting main frame 221.
The top end of the vertical section of the inverted T-shaped supporting main frame 221 is provided with an anti-falling cross bar 223.
The vertical section of the inverted "T" shaped support main 221 is provided with a positioning hole of a size matching the support base 21 and is equipped with a positioning pin 23.
When the box die main body 1 after lifting and narrowing is suspended, under the self gravity action of the telescopic supporting leg 22, the anti-falling cross rod 223 falls on the top surface of the supporting seat 21, the roller 222 falls to the ground, the positioning holes of the supporting seat 21 and the inverted T-shaped supporting main frame 221 are overlapped and fixed through the positioning pin 23 which transversely penetrates, and therefore the roller 222 can drive the box die main body 1 after narrowing and demolding and suspending to move along a main drainage ditch design path.
When the box die body 1 moves to the next stage to be poured through the roller 222, the box die body can fall back to the bottom surface from the suspension through the self gravity of the box die body 1 only by extracting the positioning pin 23.
And because the concrete pouring is carried out in a one-way and sequential manner along the designed path, as the box die main body moves to the next stage, the concrete poured in the previous stage plays a role of a rear side die, and only the side dies on two sides of the front section of the box die are required to be built, so that the task amount is reduced.
