As shown in fig. 3, two opposite ends of the hoisting base 11 are respectively provided with a lifting lug 111, and the hoisting of the hoisting base 11 can be realized by connecting the lifting lugs 111 with a steel wire rope. During assembly, the lifting lug 111 adjacent to the elongated base 12 is shielded by the elongated base 12.
In an embodiment of the present application, as shown in fig. 1 and fig. 2, the fixed bracket 71 is installed on the hoisting base 11, the movable bracket 72 is slidably fitted with the hoisting base 11 and the elongated base 12, and the fixed bracket 71 and the movable bracket 72 form a bracket unit to realize auxiliary positioning of the plurality of vertical molds 20.

The movable bracket 72 is slidably engaged with the base 10, and the movable bracket 72 is movable in a mold opening and closing direction (a general term for the first predetermined direction X and the second predetermined direction Y) with respect to the base 10. The plurality of vertical molds 20 are disposed between the fixed bracket 71 and the movable bracket 72, and the vertical molds 20 at both ends of the plurality of vertical molds 20 are connected to the fixed bracket 71 and the movable bracket 72, respectively.
As shown in fig. 4, two adjacent vertical molds 20 are connected by a flexible member 50, each flexible member 50 has the same length, and the two vertical molds 20 of the mold cavity 21 are connected by the flexible member 50, so that the adjacent vertical molds 20 are prevented from moving along with the vertical mold 20 to be opened due to the adsorption force of the concrete member during opening the mold, and the opening of the mold is prevented from being influenced. The fixed bracket 71 fixes the vertical mold 20 at one end to play a role in positioning; when the movable support 72 moves relative to the base 10, the plurality of vertical molds 20 can be gradually opened under the driving of the movable support 72 based on the flexible member 50 between the two adjacent vertical molds 20, so that the stable opening of the plurality of vertical molds 20 is ensured.
It should be noted that the flexible member 50 may be a steel wire rope, an iron chain, or the like, and has a certain connection strength to ensure the connection of the two vertical molds 20 when the mold is opened. As an alternative embodiment of the present application, the flexible member 50 is made of an iron chain, and when the two adjacent vertical dies 20 are closed, the iron chain is stacked; when the two vertical dies 20 are opened, the iron chain is unfolded until being straightened.

In order to facilitate the flexible movement of the plurality of vertical moulds 20 relative to the base 10, the vertical moulds 20 are in sliding fit with the base 10 through sliding rails.

The length of the traveling unit 90 is larger than the width of the vertical mold 20, and the levelness of the vertical mold 20 can be adjusted by adjusting the levelness of the traveling unit 90, so that unstable mold closing caused by the inclination of the vertical mold 20 is prevented.
It should be noted that, the sliding rail 60 longitudinally extends along the first predetermined direction X means that the sliding rail 60 longitudinally extends in the first predetermined direction X, and it is understood that a dimension of the sliding rail 60 in the first predetermined direction X is a dimension of the sliding rail 60 in a longitudinal direction, a dimension of the sliding rail 60 in a direction perpendicular to the first predetermined direction X is a dimension of the sliding rail 60 in a width direction, and the dimension of the sliding rail 60 in the longitudinal direction is greater than the dimension of the sliding rail 60 in the width direction.

The walking units 90 arranged in a staggered manner reduce the die sinking stroke, and are more favorable for saving energy.
Alternatively, as shown in fig. 5, two first rails 611 are respectively close to both ends of the base 10 in the width direction, and the two first rails 611 are arranged at intervals in the width direction of the base 10; the two second tracks 621 are respectively close to two ends of the base 10 in the width direction, and the two second tracks 621 are arranged at intervals in the width direction of the base 10; this arrangement can ensure that the vertical mold 20 can move flexibly relative to the base 10. Meanwhile, the first slide rail 61 and the second slide rail 62 are arranged in a manner that the position of the flexible part 50 can be avoided, so that the flexible part 50 is positioned between the first slide rail 61 and the second slide rail 62, and therefore two adjacent vertical molds 20 can be stably moved when the plurality of vertical molds 20 are opened.
Note that the width direction of the base 10 is defined to be perpendicular to the mold opening direction or the mold closing direction of the plurality of vertical molds 20.
Alternatively, each of the first rails 611 and each of the second rails 621 corresponds to one of the traveling units 90, as shown in fig. 4, each of the traveling units 90 includes a slider seat 91 and a pulley 92, the slider seat 91 extends along the first preset direction X, the length of the slider seat 91 (the size of the slider seat 91 in the first preset direction X) is greater than the width of the vertical mold 20, the slider seat 91 is detachably connected to the vertical mold 20, the pulley 92 is rotatably engaged with the slider seat 91, the pulley 92 is engaged with the corresponding rail (the general name of the first rails 611 and the second rails 621), and the pulley 92 is capable of moving along the rail. The arrangement of the pulley 92 ensures that the base 10 can move flexibly along the rail, and reduces the friction force of the vertical mold 20 moving relative to the rail.
It should be noted that, as shown in fig. 2, the plurality of vertical dies 20 includes a first end vertical die 22, a second end vertical die 23, and a plurality of intermediate vertical dies 24, and the plurality of intermediate vertical dies 24 are located between the first end vertical die 22 and the second end vertical die 23. The first end vertical die 22 is a first vertical die 20 in the first preset direction X, one surface of the first end vertical die 22 is used for being connected with the movable support 72, and the other surface of the first end vertical die 22 and the adjacent middle vertical die 24 enclose a die cavity 21 to cast and form the stair component. One surface of the second end vertical die 23 is used for connecting with the fixed bracket 71, and the other surface of the second end vertical die 23 is used for enclosing a die cavity 21 with the adjacent middle vertical die 24.
