Detailed Description

In order to make the technical solutions of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

As shown in the figure, the utility model comprises a U-shaped underframe 2 with an upward opening, a movable plate 7 horizontally arranged in the U-shaped underframe 2, clamping plates 6 symmetrically hinged at two sides of the movable plate 7 and a plurality of rollers connected with the U-shaped underframe 2, wherein the rollers comprise a universal wheel 3 arranged below one side of the U-shaped underframe 2 and two pneumatic tires 4 arranged at the other side of the U-shaped underframe 2, the pneumatic tires 4 are connected with a same rotating shaft 1 through bearings, the rotating shaft 1 is rotationally connected below the U-shaped underframe 2, the universal wheel 3 is convenient to adjust the transfer direction of a door and window 12, the pneumatic tires 4 have certain cushioning effect and can prevent the door and window 12 from being damaged by ground bumping, two guide posts 8 are vertically arranged at the bottom of the movable plate 7, the U-shaped underframe 2 is provided with guide sleeves 13 matched with the guide posts 8, the bottom ends of the guide posts 8 are in threaded connection with limit screws 14 to prevent the guide posts 8 from separating from the guide sleeves 13, the fly leaf 7 is connected with presses it to the elastic component of keeping away from 2 directions of U-shaped chassis, the elastic component is spiral spring 9, spiral spring 9 cup joints in guide pillar 8 periphery, 2 top both ends inboards of U-shaped chassis all are equipped with kicking block 10, and the interval of two kicking blocks 10 is greater than the articulated interaxial distance of both sides splint 6, and splint 6 top of both sides is all inwards buckled and is had clamping part 5, when door and window 12 placed in fly leaf 7 top, under door and window 12 deadweight, can drive clamping part 5 and press from both sides tight door and window 12 both sides, because this transportation dolly volume is less, can load door and window 12 and pass at narrow and small passage, has greatly reduced staff's intensity of labour.

The hinged parts of the two side clamping plates 6 and the movable plate 7 are provided with torsion springs, so that the clamping parts 5 of the two side clamping plates 6 are kept away under a natural state, and the door and window 12 can be conveniently placed above the movable plate 7.

The upper surface of the movable plate 7 and the tail end of the clamping part 5 of the clamping plate 6 are both covered with anti-slip pads, so that the frictional resistance between the tail end of the clamping part 5 of the clamping plate 6 and the upper surface of the movable plate 7 can be improved, and the door and window 12 is prevented from slipping from the upper side of the movable plate 7 when the door and window 12 is pushed.

Two lateral surfaces that U-shaped chassis 2 is close to the top all are equipped with handle 11, and this transportation dolly is mentioned to handle 11 of staff's accessible arbitrary one side, conveniently places this transportation dolly promptly to the position alone.

The working principle of the utility model is that when no door or window is placed above the movable plate, the spiral spring drives the movable plate to move to the upper limit position, at the moment, the limit screw abuts against the bottom end of the guide sleeve, and meanwhile, under the action of the torsion spring, the clamping parts of the clamping plates at two sides are in a far-away state; when door and window is placed above the movable plate, under the action of the dead weight of the door and window, the movable plate moves downwards, under the action of the jacking block, the clamping parts of the clamping plates on the two sides rotate towards the door and window side around the hinged shafts of the clamping plates and clamp the door and window, at the moment, the door and window can be directly pushed to transfer to the door and window through narrow and small channels in construction sites and the like, after the door and window is transferred to a destination, the door and window are lifted upwards, under the action of the spiral spring, the movable plate can reset to an upper limit position, and meanwhile, the clamping parts of the clamping plates on the two sides release the door and window. The utility model has simple structure and smaller volume, can load doors and windows to pass through a narrow passage, greatly reduces the labor intensity of workers, ensures that the clamping parts of the clamping plates at the two sides are kept away from each other under the natural state by the torsion spring, is convenient for placing the doors and the windows above the movable plate, can prevent the doors and the windows from slipping off from the movable plate when pushing the doors and the windows by the non-slip mat, can lift the transfer trolley by the lifting handle at any side, and is convenient for placing the transfer trolley to the fixed position independently.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
