Detailed Description

The following detailed description of embodiments of the utility model is provided in conjunction with the accompanying drawings:

as shown in the figure, the mould mounting trolley consists of three parts, namely a movable base 1, a lifting frame 2 and a swinging telescopic arm 3.

The mobile base 1 is composed of a bottom frame 11, a power assembly and a control assembly. The movable base 1 adopts a movable base structure of a conventional forklift. The power part uses fuel oil or electric power as power and is provided with operating devices such as an operating lever and a steering rudder. The control assembly uses conventional control circuitry, and the force determining assembly and control assembly are integrated within a housing 4 and mounted to the central rear side of the base frame 11. The bottom frame 11 is a U-shaped frame, wheels 12 are respectively installed at the middle of a cross beam of the U-shaped frame and one ends, far away from the cross beam, of two longitudinal beams, universal wheels are selected for use for two wheels on the front side, and the wheels on the tail portion are connected with a steering engine 13 so as to control the direction conveniently. The U-shaped bottom frame and the rear power assembly are adopted to control the center of the mold vehicle, so that the mold vehicle is prevented from being turned over forwards when the mold vehicle carries a mold.

The crane 2 consists of a horizontal support surface 21 and a vertical support frame 22. Both sides of the horizontal support surface 21 are engaged with slide rails inside a pair of longitudinal beams of the bottom frame 11, so that the horizontal support surface 21 can be extended or retracted from the bottom frame 11 to the outside, and position adjustment in the advancing direction is realized. In order to make the adjustment smoother, at least one horizontal hydraulic telescopic cylinder is arranged between the side surface of one side, facing the bottom frame 11, of the horizontal supporting surface 21 and the inner side surface of the cross beam of the horizontal frame, the hydraulic telescopic cylinder is used for driving the horizontal supporting surface 21 to stretch, meanwhile, a roller is arranged at the bottom of the horizontal supporting surface 21, and the roller supports the horizontal supporting surface and reduces the friction force in the stretching process of the horizontal supporting surface. The vertical support frame 22 is fixedly and vertically installed on the horizontal support surface 21 and is used for supporting the swing telescopic arm 3.

The swing telescopic arm 3 is composed of a boom assembly 31 and a boom support 32. The cantilever support 32 comprises two parts, a support frame 321 and a rotational support 322. The support frame 321 is mounted on the vertical support frame 22 by rails and moves up and down along two vertical beams of the vertical support frame 22. The inner sides of two vertical beams of the vertical support frame 22 are respectively fixedly provided with a vertical hydraulic cylinder 5 and a chain wheel 6, the chain wheel 6 is positioned above the stroke range of the support frame 321, and the telescopic ends of the support frame 321 and the vertical hydraulic cylinder 5 are connected through a chain 7 wound on the chain wheel 6. When the two vertical hydraulic cylinders 5 are contracted simultaneously, the chain 7 pulls the support frame 321 to move up along the rail by reversing the chain wheel 6. The boom assembly 31 is installed at the support frame 321, and the boom assembly 31 follows the up-and-down movement.

To increase the dimension of the adjustment of the mould carriage, the boom assembly 31 is mounted to the support frame 321 by a pivot support 322. The rotating support 322 comprises a rotating seat 3221 and a rotating column 3222, and the rotating seat 3221 is fixedly welded to the front end face of the support frame 321.
