Dump barrow

Abstract

The invention relates to an easily-detached and conveniently-folded trolley dumper with high dumper strength made of the same material as a trolley handle bar and a trolley side beam. Dumper wheels are connected with a trolley frame chassis, a dumper hopper is positioned on the trolley frame and can be turned over. Side beams of two steel pipes of the trolley frame are bent and molded with the same steel pipe as the two handle bars of the trolley respectively. Both ends of a front steel pipe beam and a back steel pipe beam between the side beams of the two steel pipes of the trolley frame are welded with the side beams of the two steel pipes respectively, and both ends of a core beam of a steel pipe frame of the trolley are welded with the front steel pipe beam and the back steel pipe beam. The lower part of the front part of both sides of the dumper hopper is connected with the front steel pipe beam of the trolley frame through a connecting lug and can be rotated, and a hopper port of the dumper hopper is welded with a corner-shaped reinforced edge. The trolley dumper has the advantages that the integral strength of the trolley frame is high, and the stability is good; the trolley dumper can be disassembled, a plurality of dumper hoppers can be stored by folding so as to be convenient for transport and storage, and the transport cost and storage cost are low; and the peripheral corners of the hopper port of the dumper hopper cannot be shoved off, and the strength of carriage plates is reinforced.

Description

technical field [0001] The invention relates to a trolley dump truck which is easy to disassemble, easy to superimpose, has a high strength trolley frame, and is made of the same material as the handlebar of the trolley and the side beam of the trolley frame, belonging to the field of dump truck manufacturing. Background technique [0002] Authorized announcement number CN2592470Y, name "trolley", the push cart is composed of a hopper, a frame, and wheels, the wheels are installed on the axle, the axle passes through the axle cover plate, and is fixed on the connecting plate of the frame by bolts, the hopper passes through the hinge seat and The hinged cover plate is installed on the front frame by bolts, and the locking nails at the rear and lower part of the hopper cooperate with the locking plate on the horizontal support of the frame to lock. The vehicle frame is U-shaped and integrated with the handlebar. A horizontal angle steel support is installed between the two han...

Problems solved by technology

Its shortcomings: First, because the frame adopts the whole steel pipe to bend into a U-shaped frame and handlebar, that is to say, there is no welding point between the two ends of the front transverse support of the frame and the supports on both sides of the frame.

The problem with this structure is that even if a horizontal angle steel support is installed between the two handlebars in the vehicle frame, there is a vertical angle steel support between the horizontal angle steel support and the front frame, and the vehicle frame formed by it is pushing between the two handlebars. When pushing a trolley, due to the influence of the road surface and the unequal strength of the left and right arms of the person, the left and right torsional forces generated by the wheels and handlebars directly pass through the U-shaped front support to form a back-and-shear circuit, thereby causing the frame to twist left and right, especially when the trolley is full. When the load is heavy, the frame twists up and down with the unevenness of the road surface, which not only easily damages the frame, but also makes it difficult for the trolley operator to maintain the overall stability of the car body; The horizontal angle steel support is installed between the bars, and the longitudinal angle steel support is installed between the horizontal angle steel support and the front frame

Angle steel is an open profile, and the strength of the profile depends on the size of the angle steel. For the trolley, du
