The demoulding device 3 is used for pulling off the outer mould of the reinforced concrete member, can be arranged in a plurality of ways, and applies pulling force to the mould simultaneously, so that the stress of the mould is more uniform. The height adjusting devices 2 and the stripping devices 3 are arranged in a one-to-one correspondence mode, the height of each stripping device 3 is adjusted independently, and the most appropriate pulling-off position can be selected according to different shapes of the components. The anti-overturning device 4 is used for placing the die to overturn and damage the demoulding vehicle after the die is pulled down, and injures operators.

The frame 1 is a structure for carrying other demoulding components and providing better mobility, and comprises a plurality of wheels 11 capable of freely rotating, and preferably, a braking device or a locking device can be arranged on the wheels 11, so that the wheels can be locked during demoulding operation, and accidental sliding is avoided. The frame 1 is also provided with an anti-collision beam 12, and the anti-collision beam 12 is abutted against the carrier 8 of the concrete member 6 during demoulding so as to provide supporting force for the drawing-off mould 7. The carrier 8 is fixedly connected with the component 6, can convert the demoulding pulling force into the internal force between the mobile demoulding vehicle and the component 6, does not need external fixation during demoulding,

the height adjusting device 2 is arranged on the frame, connected with the demoulding devices 3 in a one-to-one correspondence manner and used for adjusting the height of the demoulding devices 3. In this embodiment, in order to simplify the structure of this mobile demolding vehicle, the height adjustment device 2 adopts a simpler manual adjustment mode, including the threaded column 21 and the fixing nut 22, the outer side surface of the threaded column 21 is provided with a thread, and is vertically arranged on the frame 1, and the lower end is fixedly connected with the frame 1. At least two fixing nuts 22 are screwed on each threaded post 21, and the fixing nuts 22 can move up and down by rotating around the threads. A part of the demoulding device 3 is sleeved on the threaded column 21, two fixing nuts 22 are respectively positioned on the upper side and the lower side of the part, and the height of the demoulding device 3 is adjusted and fixed by moving the demoulding device 3 to a proper position and clamping the part by using the two fixing nuts 22.

The demoulding device 3 comprises a speed reduction gear box 31, a demoulding hand wheel 32, a demoulding rack 33, a connector 34 and a demoulding draw hook 35. The shell of the reduction gear box 31 is provided with a connecting hole, and the connecting hole is sleeved on the threaded column 21 and can freely slide on the threaded column 21. I.e. the stripping means is fixed by clamping the site by means of the fixing nut 22. The demoulding hand wheel 32 is connected with the power input end of the reduction gear box 31, the power output end of the reduction gear box 31 is meshed with the rack 33, and one end of the rack is connected with the demoulding drag hook 35 through the connector 34. Drawing of patterns drag hook 35 rotates with connector 34 to be connected, overlaps to be equipped with torsion spring on the axis of rotation for drawing of patterns drag hook 35 can collude tight mould 7 when the drawing of patterns.

In this embodiment, the reduction gear box 31, the demolding hand wheel 32 and the demolding rack 33 constitute a linear displacement mechanism to drive the demolding hook 35 to pull the mold 7. The mechanism is easy to know, and provides power for an operator to pull the demoulding drag hook 35 to move by manually rotating the demoulding hand wheel 32. In other embodiments, other structural forms, such as an electric cylinder, a hydraulic cylinder, and the like, may also be adopted to achieve the same technical effects in the present embodiment.

In addition, in the actual use process, a technician can select a reduction gear box 31 with a proper transmission ratio according to the actual size of the mold 7, so that an operator can smoothly pull out the mold 7 by manually rotating the demolding hand wheel 32.

The anti-overturning device 4 is arranged above the demoulding device 3 and used for preventing the mould from overturning and injuring field operators or smashing the demoulding vehicle when the mould 7 is pulled down. The anti-tipping device 4 comprises an anti-tipping push plate 41, a transmission shaft 42 and an adjusting hand wheel 43, wherein the side surface of the transmission shaft 42 is provided with a thread, the frame 1 is correspondingly provided with a threaded hole, the middle part of the transmission shaft 42 is meshed and connected with the threaded hole, one end of the transmission shaft is fixedly connected with the adjusting hand wheel 43, and the other end of the transmission shaft is rotationally connected with the anti-tipping push plate 41. The anti-tipping push plate 41, the demoulding drag hook 35 and the anti-collision beam 12 are positioned on the same side of the frame 1 and face the mould 7 when demoulding is carried out. The operator can manually rotate the adjusting hand wheel 43 to drive the anti-tipping push plate 41 to move back and forth through the rotating shaft 42. The shape of the anti-tipping push plate 41 is matched with the mould 7, when the mould 7 impacts the anti-tipping push plate 41, the largest stress area can be obtained, and the pressure intensity is reduced.

When the demolding operation is performed, firstly, an on-site technician determines the most appropriate pulling-out point according to the shape and the size of the mold 7, then pushes the movable demolding vehicle to the position, so that the anti-collision beam 12 abuts against the carrier 8 below the mold 7, then adjusts the demolding device 3 to the appropriate height through the height adjusting device 2, then rotates the demolding hand wheel 32, so that the demolding drag hook 35 moves to the mold 7 to the appropriate distance, and then rotates the demolding drag hook 35 to hook the mold 7. Turning the adjusting handwheel 43 again moves the anti-tip push plate 41 towards the mould 7 until it is close to the mould 7 but maintains a small gap, about 10 cm, with the mould 7. Thus, all preparation work of the demoulding operation is completed, and then the operator rotates the demoulding hand wheel 32 at the same time to enable the demoulding drag hook 35 to drive the mould 7 to move towards the direction far away from the component 6 until the two are separated. If the mould 7 is tipped, the mould can be caught by the anti-tipping push plate 41, and the safety of the personnel and equipment below is protected.
