Embodiment 1

[0033] Embodiment 1: See accompanying drawing 1, accompanying drawing 2, shown in accompanying drawing 3, a kind of hand-push truck that can lift, comprises an upright vehicle frame 1, and described upright vehicle frame 1 is the upright column that is made of two hollow tubes 2, and a closed-loop frame composed of a hollow-controlled top beam 21, a middle beam 22, and a bottom beam 23 connected between the two columns 2 on the upper, middle, and lower sides, and the two columns 2, the middle beam 22, and the bottom beam 23 The inner cavity of the hollow tube is connected with each other to form a square closed-loop channel. The bottom of the frame is provided with two coaxial walking wheels 3 (it can also be four four corners arranged walking wheels 3); the upright vehicle frame 1 is provided with a shelf 4 forward, and the shelf 4 is opposite. The upright vehicle frame 1 is slidably connected up and down. A lifting and suspending mechanism is provided between the upper part...

Embodiment 2

[0044] Embodiment 2: Referring to accompanying drawings 1 and 4, a liftable hand-push truck includes an upright vehicle frame 1, a shelf 4, walking wheels 3, a lifting suspension mechanism, and a chain tensioning mechanism. The storage mechanism and the inverted pull stabilization mechanism are different from Example 1 in that: the relative fixed ends of the first extension spring section 18 and the second extension spring section 19 are directly fixed on the upright vehicle frame 1, and each is an independent tension spring. Others are the same as those in Embodiment 1, and will not be repeated here.

Abstract

The invention provides a lifting hand-pushing van, comprising a vertical frame which includes an enclosed frame formed by hollow pipes; the bottom of the frame is provided with a walking wheel; the vertical frame is connected with an object arranging frame in a sliding way; a lifting hoisting mechanism is arranged between the upper part of the vertical frame and the object arranging frame; the lifting hoisting mechanism consists of a pulley block, a traction rope, a mainshaft and a reverse rotary self-locking device. The invention is characterized in that the traction rope is a chain; the last crown block of the pulley block is a drive chain wheel which is fixedly connected with the mainshaft which is connected with a power source by the reverse rotary self-locking device; the invention also comprises a chain tensioning and intake mechanism consisting of a first cable wire, a first guide wheel, a first movable wheel and a first pulling spring section, and a backing tensile stabilizing mechanism consisting of a second cable wire, a second guide wheel, a second movable wheel and a second pulling spring section; the invention has the advantages of good strength of chain, being not easy to be broken or be disconnected from the wheel, reliable operation, and high safety.

Description

technical field [0001] The invention relates to a hand-push type transport vehicle, in particular to a hand-push type transport vehicle with a liftable rack. Background technique [0002] Hand truck is the most common means of transportation in people's daily life and various industrial production activities. It is simple in structure and low in cost, and is especially suitable for carrying goods of several hundred kilograms in a short distance. [0003] The shelves of the earlier hand trucks were all fixed and could not be raised and lowered. When loading and unloading goods, manual lifting was required. When the destination of loading or unloading goods was higher than the shelf, loading and unloading was even more difficult. Time-consuming and labor-intensive, many workers are required to cooperate with the operation, and the work efficiency is low. [0004] Therefore, a hand truck with a lifting device appeared later, so that the shelf can be lifted up and down, which ...
