The utility model provides a carriage steel-aluminum connection structure to steel-aluminum structure between high strength connection boxcar curb plate and the bottom plate is exclusively used in.
In order to achieve the above purpose, the utility model discloses a scheme does: carriage steel-aluminum connection structure, including four bight connecting portion and at least a pair of waist connecting portion, all be equipped with the riveting hole on bight connecting portion and the waist connecting portion, bight connecting portion include bight connecting rod and bight locating plate, and the transversal L shape of personally submitting of bight connecting rod, the cross section of bight locating plate are two steps of echelonment, forms the right angle after bight locating plate and the laminating of bight connecting rod medial surface, and waist connecting portion include waist connecting rod and waist locating plate, and the cross section of waist connecting rod and waist locating plate is the U-shaped.
The working principle and the beneficial effects of the scheme are as follows: on four bight locating plates all were fixed in four angles of carriage bottom plate through modes such as welding, riveting, the one side outside and the outside of guaranteeing the bight connecting rod of bight locating plate and corner connecting rod laminating can align with the bottom plate. The waist positioning plate is fixed at the middle part of the side edge of the bottom plate with the opening facing outwards. The corner connecting rod and the corner positioning plate, the waist connecting rod and the waist positioning plate are riveted through the riveting holes, the side plate of the carriage body is fixedly riveted with the waist connecting rod and the corner connecting rod, and the carriage side plate and the bottom plate can be connected, so that the high-strength connection of a steel-aluminum structure between the carriage side plate and the bottom plate is realized.
Optionally, a corner protection plate is further included, the corner protection plate being L-shaped, the two sides of the corner protection plate extending beyond the two sides of the corner positioning plate. After the corner connecting rod and the corner positioning plate are attached, the two side edges of the corner protective plate can exceed the joint of the corner connecting rod and the corner positioning plate, and the joint seam of the joint and the corner connecting rod are enclosed together in the corner protective plate for protection.
Optionally, the corner connecting rod is formed by splicing three rectangular frames end to end on the cross section. And the frame-type section structure is adopted, so that the weight is reduced while the structural strength is ensured.
Optionally, one surface of the corner positioning plate facing the corner connecting rod is provided with a first seam which protrudes outwards and faces downwards, and the side surface of the connecting rod is provided with a first groove which is matched with the first seam. Support in first recess through first seam, let bight locating plate can be upwards spacing in vertical downward place, share the atress of riveting department for the connection between bight locating plate and the bight connecting rod is more firm.
Optionally, one side of the waist positioning plate facing the waist connecting rod is provided with a second seam which protrudes outwards and faces downwards, and the side of the connecting rod is provided with a second groove matched with the second seam. Except that the connection between waist locating plate and the waist connecting rod is more firm, when the waist connecting rod is installed, the second bite can be utilized to borrow force, and the location of the waist connecting rod is more convenient.
Drawings
FIG. 1 is a schematic view of the connection structure to the floor of the vehicle compartment according to an embodiment of the present invention;
fig. 2 is a schematic view illustrating a connection between the second engaging opening and the second groove according to an embodiment of the present invention.
Detailed Description
The following is further detailed by way of specific embodiments:
