Labor-saving building cart

Abstract

The invention discloses a labor-saving building cart. The labor-saving building cart comprises a cart hopper base, a cart hopper, handles, a wheel assisting mechanism and a downhill speed reducing mechanism, wherein the cart hopper base is of an L-shaped structure, the cart hopper is longitudinally connected to the part, which is parallel to the ground, of the cart hopper base in a sliding mode byvirtue of a plurality of damping springs, the two handles are fixed to the part, which is perpendicular to the ground, of the cart hopper base, a shaft seat is perpendicularly fixed to the bottom endof the car hopper base, wheel shafts which are parallel to the ground are rotatably connected to the shaft seat, and two wheels are fixed to each wheel shaft by virtue of one-way bearings; and the assisting mechanism comprises assisting gears which are fixed to the two one-way bearings and two rack plates which are fixed to the bottom end of a guide sliding block, perpendicularly penetrate through the cart hopper base, extend to the position below the cart hopper base and are matched with the two power assisting gears. According to the labor-saving building cart, when the cart is pushed to advance on the construction site with pavement irregularity, the cart can vibrate, and the vibration force generated by vibration is converted into power of the wheel power assisting mechanism so as toassist the cart to continuously advance, so that the labor-saving effect is achieved.

Description

technical field [0001] The invention relates to the technical field of construction carts, in particular to a labor-saving construction cart. Background technique [0002] With the continuous development of the construction industry, in order to speed up the construction of houses. Construction trolleys are usually used to transport construction materials where large machinery cannot operate. Construction trolley is a relatively common means of transportation in the construction industry. It is easy to use, can transport various materials, has high efficiency, low cost and long service life. [0003] However, the structure of existing construction carts is simple, and there are still some deficiencies in use. For example, because the construction site often has large cargo vehicles coming and going, the construction site will be crushed and pits will appear, making the ground uneven. When the staff pushes the trolley on the above-mentioned ground, it is easy to get stuck o...

[0003] However, the structure of existing construction carts is simple, and there are still some deficiencies in use. For example, because the construction site often has large cargo vehicles coming and going, the construction site will be crushed and pits will appear, making the ground uneven. When the staff is pushing the cart on the above ground, it is easy to get stuck on the uneven ground. At this time, the staff needs to spend a lot of effort to push the cart away, which is more laborious
