Fig. 1 is a front view of the structure of the present invention.
Fig. 2 is a top view of the structure of the present invention.
Fig. 3 is a schematic view of a ladder of the present invention.
In the figure: 1-handle bar, 2-frame, 3-rope adjuster, 4-support bar, 5-wheel, 6-support plate, 7-elastic element I, 8-elastic element II.
Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without any inventive effort, are intended to be within the scope of the invention.
As shown in fig. 1 and 2, a stair climbing transport trolley comprises a handle bar 1, a frame 2, a rope adjuster 3, a supporting rod 4, wheels 5, a supporting rod 6, an elastic piece I7 and an elastic piece II8.
Wherein frame 2 is main body frame structure, can put the material that needs to transport on the frame, and frame 2 includes two frame longitudinal bars, welds a plurality of frame horizontal poles between two frame longitudinal bars, and the welding has the shelves pole between two frame longitudinal bars, and the shelves pole is located the front end of frame longitudinal bar for keep off to establish the material, avoid the material to drop.
The rear end of the frame 2 is provided with a handle rod 1, the handle rod 1 is sleeved on the frame 2, clamping holes are formed in the handle rod 1 and the frame 2, clamping pins are arranged in the clamping holes, the handle rod is fixed on the frame by means of the clamping pins, and meanwhile the length of the handle rod can be adjusted according to requirements, so that the front end of the frame is lifted more labor-saving. The front end of the frame 2 is provided with wheels 5 which can walk on steps for the movement of the trolley.
The middle part of the frame 2 is welded with a sleeve seat, and the sleeve seat is hinged with the upper end of the supporting rod 4, so that the frame can rotate relative to the supporting rod, and the wheels of the vehicle can lift up the first-stage steps. The lower extreme of branch 4 is connected with the one end of stay cord, and the other end of stay cord is connected with transfers rope ware 3, transfers rope ware 3 cover and establishes in the rear portion of frame 2, transfers rope ware 3 and can dismantle with frame 2 through the bolt and be connected, unscrews the bolt, can realize transferring the adjustment of rope ware 3 position on frame 2. Through the restriction of stay cord, restriction branch is 90 with the biggest contained angle of frame, can avoid the whereabouts of frame, avoids the frame to move backward and takes place danger.
The front side of the supporting rod 4 is hinged with an elastic piece I7, and the elastic piece I7 is hinged with one end plate of the supporting plate 6, so that the elastic supporting limit of the supporting rod to the supporting plate is realized. The front part of the frame 2 is hinged with an elastic piece II8, the elastic piece II8 is hinged with the other end plate of the supporting plate 6, and the elastic support limit of the frame to the supporting plate is realized. The supporting plate is L-shaped and is used for being attached to the right angle of the protruding step, and the elastic piece I and the elastic piece II are utilized to damp and buffer the frame.
As shown in fig. 3, when the trolley performs a ladder operation, the supporting rods are used as supporting bases, and the supporting plates are clamped at the right angle of adjustment. The handle bar is pressed down to lift the front end of the frame, and the operation is labor-saving due to the fact that the handle bar is long. At this time, the elastic piece I is not deformed, the elastic piece II is restored, and the upward elasticity of the elastic piece II can also enable the front end of the frame to be lifted more conveniently. The height of the frame lifting should be appropriate to avoid the frame and the material having a high potential energy. The L-shaped structure and the elastic piece of the supporting plate can clamp the supporting plate at a right angle without moving. At this moment, the frame is pushed forward for the branch takes place to incline, then gravity makes the dolly fall by automatic forward tilting, and elastic component I and elastic component II compression deformation continuously provide ascending buffer force for the dolly, effectively avoid the car to roll up the influence of gravity, directly fall on last step, cause the great vibration of frame, the problem that the material dropped easily. After the wheels fall to the previous step, the rear end of the frame is lifted to push the trolley to walk.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
