Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of mine truck loading structure, specifically relates to a mine truck U-shaped container side plate structure and mine truck. BACKGROUND

[0002] Now mine truck loading box body generally has two structure forms: rectangular box and U-shaped box. Rectangular box is less and less used in many mine truck loadings due to complex structure and heavy weight, gradually adopts the box body structure form that the side plate is U-shaped. This U-shaped side plate is welded with the front plate in front and the bottom plate in the bottom, and is installed with the back plate in the back, so as to form a complete box body structure form. Installed on the mine truck chassis, loads the goods, and then falls the material by the lifting oil cylinder installed on the front plate, so as to form the whole process from transportation to dumping of the goods.

[0003] The side plate structure of the current U-shaped container is basically realized by bending the side plate multiple times, and a plurality of cross beams and longitudinal beams are fixedly installed on the outer side of the side plate to play a reinforcing role, so as to ensure that the overall strength of the side plate structure meets the use requirements of the mine truck.

[0004] However, the overall structure of this side plate structure is complex, the production and assembly cycle is long, and the plurality of cross beams that play a reinforcing role will lead to a large overall weight, high empty load oil consumption and poor economy. UTILITY MODEL CONTENTS

[0043] Example 1

[0044] like Figure 1 As shown, the side panel 1 structure of the U-shaped cargo box for mining trucks provided by this utility model includes: side panel 1, upper beam 2, reinforcing column 3 and skirt structure 4. The upper beam 2, the two reinforcing columns 3 at the front and rear ends and the skirt structure 4 at the bottom generally form a frame structure, which is fixed around the side panel 1.

[0045] The side plate 1 comprises a first bending part 101, a reinforcing bending part 102 and a second bending part 103 which are sequentially formed by bending from top to bottom, and the reinforcing bending part 102 is protruded towards the inner side, and the reinforcing bending part 102 arranged between the first bending part and the second bending part 103 can resist impact and strengthen the connection strength between the first bending part 101 and the second bending part 103.

[0046] The upper side beam 2 is fixed to the upper part of the outer side of the side plate 1, and the reinforcing column 3 is fixed to the outer side of the side plate 1 along the length direction of the upper side beam 2, and two reinforcing columns 3 are fixed at the two ends of the upper side beam 2, and at least one reinforcing column 3 is further fixed between the two reinforcing columns 3, which is close to the reinforcing column 3 at the tail end, and plays a role in strengthening the tail part of the formed container, avoiding the structure of the side plate 1 from appearing bulging at the tail part, and the top of the reinforcing column 3 is connected with the upper side beam 2, and the bottom extends to the lower part of the side plate 1, and the skirt structure 4 is arranged at the bottom of the outer side of the side plate 1, and the skirt structure 4 is connected with the bottom of the reinforcing column 3.

[0047] Compared with the previous structure in which the tension is provided by the connection between the bottom of the side plate 1 and the bottom plate, and the supporting force is provided by the lower supporting beam, the application improves the impact resistance and overall rigidity of the side plate 1 by arranging the reinforcing bending part 102, and since the reinforcing bending part 102 in the side plate 1 is protruded towards the inner side and connected between the first bending part 101 and the second bending part 103, the overall structure of the reinforcing bending part 102 forms a triangular structure towards the inner side, which has better structural strength compared with the previous structure which is continuously bent in one direction, so that the side plate 1 itself has better supportability, and the middle cross beam and the like can be omitted to achieve the strength requirement, and the overall weight and cost are reduced, so that the economy of the vehicle is greatly improved.

[0048] Specifically, the reinforcing bending part 102 comprises a first reinforcing bending plate 1021 and a second reinforcing bending plate 1022.

[0049] The bottom of the first reinforcing bending plate 1021 is offset and bent towards the inner side, the top of the first reinforcing bending plate 1021 is connected with the bottom of the first bending part 101, the offset direction of the entire reinforcing bending part 102 is controlled by the bottom of the first reinforcing bending plate 1021, the top of the second reinforcing bending plate 1022 is connected with the bottom of the first reinforcing bending plate 1021, the bottom of the second reinforcing bending plate 1022 is offset and bent towards the outer side, the bottom of the second reinforcing bending plate 1022 is connected with the top of the second bending part 103, and the second reinforcing bending plate 1022 is offset towards another direction, so that the reinforcing bending part 102 forms a reinforcing structure which is protruded towards the inner side; wherein the inner side and the outer side are respectively the inner side and the outer side of the container on which the side plate 1 structure is installed.

The lower end of the support plate 401 extends inwardly to be fixedly connected with the bottom plate assembly 7 of the cargo box. The bottom of the side plate 1 is also fixedly connected with the bottom plate assembly 7 of the cargo box. Compared with the conventional support plate 401 which only reinforces the outer side of the second bent part 103, the support plate 401 connects the bottom plate assembly 7 and the side plate 1 together to form mutual support and reliance, thereby improving the structural strength of the connection between the bottom plate assembly 7 and the side plate 1.
