Description

lifting trolley

technical field

The invention relates to a trolley, in particular to a lifting trolley which is convenient for people to easily lift heavy objects from the ground onto the trolley.

Background technique

At present, the known structure of various trolleys is composed of wheels, loading platforms and handrails, and the wheels can facilitate people to save energy during transportation. However, general trolleys do not have the function of allowing people to easily lift heavy objects from the ground to the loading platform. When people lift heavy objects and place them on the loading platform, various parts of the limbs are stressed, especially the waist. prone to labor injuries. Some hydraulically powered tank trucks can lift specially shaped tanks, but are expensive and can only lift special items.

Contents of the invention

In order to overcome the shortcoming that common trolleys cannot conveniently move heavy objects from the ground to the cart, the present invention provides a lifting trolley, which can not only move heavy objects from the ground to the cart effortlessly, but also has low price and no material parts. easy access. The use of the trolley can reduce labor injuries. Especially when the elderly live alone at home, they often need to carry some heavy objects, such as gas tanks, buckets, water tanks, etc., which are in great need of the help of the present invention.

The technical scheme that realizes the object of the present invention is:

Set a gantry frame with a base, set wheels on the base of the frame, set handrails on the upper part of the frame to form a trolley, and hang a heavy platform that can swing back and forth at the same height on the inside of the two columns in the middle and lower parts of the frame , The middle part of the gantry frame is provided with a horizontal bar, and the top of the gantry frame is provided with a lifting mechanism.

The lifting mechanism is composed of a winch, a handle, a bicycle flywheel and a cable. The handle is fixed at one end of the winch. One end of the winch has a simple clutch, which can be coupled or separated from the bicycle flywheel fixed on the gantry frame. One end of the cable is Attached to a winch and connected to a weight at the other end.

The simple clutch is composed of a winch and a screw that passes through the winch and engages with the bicycle flywheel.

The bicycle flywheel has a ratchet self-locking structure inside, which is a national standard part.

When in use, push the trolley to the side of the heavy object, swing the heavy object platform back, tie the heavy object with a cable, crank the hinge to raise the heavy object, reset the heavy object platform under the heavy object, and move the trolley, you can Move the heavy object to the destination, lift the heavy object, remove the heavy object platform, and put the heavy object down.

The advantages of the present invention are: the trolley can not only move heavy objects from the ground to the trolley in a labor-saving manner, but also has a simple structure, low price, and easy-to-obtain material parts, and the use of the trolley can reduce labor injuries, especially when the elderly live alone at home , often need to carry some heavy objects, such as gas tanks, buckets, water tanks, etc., need the help of the present invention very much.
