Abstract
Embodiments of the invention relate to hoppers for heavy trucks and, more particularly, to hoppers capable of being moved in parts and methods for assembly thereof. In some embodiments, such hoppers comprise a front part, a hood in two parts, two side front parts, two intermediate side sections, two side floor sections, two central floor sections, base plates being joined by welds and secondary joints joined by bolted flanges.
Claims4
A hopper for heavy mining trucks which is moved disassembled and assembled in the construction site in two days, saving time and costs of transport, assembly and use of cranes, comprising:
- a) two central floor sections (5, 6) including:
- floor base plates (12) which are curved (15) in the front of the hopper;
- a front column section (23);
- hopper chassis (22);
- and
- a plurality of floor beams sections (19), which are joined to each other, with the right (4) and left (7) side floor sections and the front (1) using flanges (10) and welds (13) of the plate bases;
- b) two right (4) and left (7) floor sections, including:
- floor base plates (12) which are curved (15) in the front part of the hopper;
- a lower side section (21);
- and
- a plurality of floor beams (19) where said two right (4) and left (7) floor sections join the two intermediate side sections (3), the intermediate floor sections (5, 6) and also the front part (1) using flanges (10) and welds (13) of the base plates;
- c) two intermediate side sections (3) which are joined each on one side with the two front side sections (2), and on the other side with two right (4) and left (7) side floor sections, the floor (12) and the front part (1) using flanges (10) and welds (13) in the base plates;
- d) two front side sections (2) containing a base plate (18) which join two intermediate side sections (3), the hood (8, 20) and the front part (1) using flanges (10) and welds on the base plates;
- e) a front part (1) containing two front columns (11), joined to the hood (8), the floor (12) and the sides (2, 3) using flanges (10) and welds on the base plates;
- and
- f) two hood parts (8, 20) joined to each other, the top of the front part (1) using welding of the base plate and flanges (10) or only welding, and two front side sections (2) using flanges (10) and welds on the base plates.
A method for assembling a hopper for heavy mining trucks that is moved disassembled and assembled in the construction site in two days, saving time and costs of transport, assembly and use of cranes, comprising the steps of:
- a) providing a disassembled hopper;
- b) joining the floor sections (4, 5, 6, 7) using the plurality of flanges (10) in the plurality of floor beams (19);
- c) joining the two intermediate sides (3) using flanges (10) with the left (7) and right (4) floor sections;
- d) joining the two intermediate sides (3) using flanges (10) with the two front sides (2), this point may be carried out before point c), optionally, the base plates of these two sets (2, 3) may be welded in this stage;
- e) joining the floor (12) and side (2) plates with the front part (1) using flanges (10);
- f) joining the front part (20) of the hood with the back of the hood (8) using flanges (10), optionally, the base plates of these two sets (8,20) may be welded at this stage;
- g) joining the hood (8) with the front part (1) and the front sides (2) using flanges (10);
- h) welding the floor plates (12) to each other with longitudinal welding seams (13);
- i) welding the two side plates (9) which form a part of the intermediate side (3) to the upper edge (16) of the right (4) and left (7) floor sections and the lower edge (17) of the plate (18) included in the front side sections (2);
- j) welding the front part (1) to the floor (4, 5, 6, 7) and the intermediate (3) and front (2) sides;
- and
- k) welding the hood (8,20) to the front part (1) and the front sides (2).
