A construction site handling device based on elastic assisted climbing stairs

Abstract

The invention relates to the field of construction technology, and discloses a construction site transport device based on elastic force-assisted climbing stairs, including a storage platform, the front of the storage platform is fixedly connected with a baffle plate, and the rear side of the bottom of the storage platform is rotatably connected There are rollers, and a shrinking device is fixedly installed on the lower side of the front of the baffle, and a bouncing frame is movably connected inside the shrinking device, the bottom of the baffle is rotatably connected to a rotating shaft, and the outer wall of the rotating shaft is provided with a connecting frame, The end of the rotating shaft is provided with a stopper. The construction site handling device based on elastic assisted stair climbing, when it needs to shrink, touches the foot switch with the foot, thereby driving the foot switch to squeeze the limit rod to the left, thereby driving the limit rod to return to the original position, To complete the contraction function of the jumping frame, when climbing stairs, it is necessary to apply an upward pulling force to the pull plate, so as to drive the three-legged stair climbing wheel to contact the stairs to climb the stairs, saving the physical strength of the workers.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a construction site transport device based on elastic force to assist climbing stairs. Background technique [0002] In the construction site, when carrying some scattered goods that can be consigned with you, the cart is usually used as an auxiliary tool, which is not only labor-saving, but also convenient to use. When pushing and pulling the cart on the flat ground, the wheels can bear the gravity of the goods. Just use the pulling force forward, which saves time and effort, but when going upstairs, people have to bear the weight of the goods and pull the cart upwards to climb the stairs, which is quite laborious. [0003] At present, there are many stair-climbing carts on the market, such as three-wheel rotary trailers, four-wheel (cross) wheel carts, small wheels with large wheel carts, etc. Only by pulling the cart can you go up a step. When you need to go up and down ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a construction site transport device based on elastic force-assisted stair climbing, which is equipped with the use of tripod climbing wheels to save physical strength, and the use of bouncing frames and rubber pads to convert gravitational potential energy into elastic potential energy. It has the advantages of one-time stair-climbing, easy to retract, and easy to brake, which solves the problem that the existing carts are laborious to climb stairs and do not have a braking function when going downstairs.
