Problems solved by technology

The truck compartment manufactured by welding has the following defects: (1) During the welding process, the welded workpiece is affected by the uneven temperature field, and it is easy to produce shape or size changes, that is, we often say welding deformation, welding deformation It has a great impact on the installation accuracy of the structure. Excessive deformation will significantly reduce the bearing capacity of the structure, so the bearing capacity of the carriage cannot be guaranteed; (2) The strength of the weld seam formed after welding cannot be guaranteed. In the middle, if the vibration of the carriage will cause the weld to vibrate, the long-term vibration will cause the weld to scatter, and the carriage at this time cannot continue to be used normally; (3) The welding operation will pollute the surrounding environment. In order to meet the environmental protection requirements, the The requirements of the welding process are high, so the welding cost is high

Embodiment 1

[0040] The invention discloses a compartment connector, such as figure 1 As shown, the compartment connector includes a connecting part 1 and a plug-in part 2, and the connecting part 1 is a tetrahedron. In this embodiment, the connecting part 1 is a cuboid, and its interior is a cavity. Inserting parts 2 are respectively fixed at the same end of the mutually perpendicular sides, and the inserting parts 2 are two parallel inserting boards 3 , and one end of the inserting boards 3 is fixedly connected with the side of the connecting part 1 . Glue grooves 4 are provided on the side of the connecting portion 1 that is not provided with the plug-in portion and the outer surface of the plug-in board 3. By setting the glue groove 4, the sealant can be placed in the glue groove, and the sealant connects the compartment profile with the compartment. The connecting pieces are glued together, realizing the fixed connection between the connecting pieces of the carriage and the profiles o...

Embodiment 2

[0044] The invention also discloses a compartment comprising the above-mentioned compartment connector, such as figure 2 As shown, the compartment includes a compartment profile, a cladding plate 13, a compartment roof 15 and a pressure plate 21, and the compartment profile includes a compartment column 5, a compartment bottom longitudinal beam 6, a compartment bottom beam 7, a compartment top beam 11, a compartment top longitudinal beam 12, a compartment The middle vertical beam 8, the carriage middle column 9 and the carriage door frame 10. Wherein, the compartment column 5 and its adjacent compartment bottom longitudinal beam 6 and compartment bottom beam 7 are fixedly connected by a tee connector and a pressing plate 21, and the compartment column 5 and its adjacent compartment top beam 11 and compartment top longitudinal beam 12 are fixedly connected to each other. The space is fixedly connected by a three-way connector and a pressing plate 21. The three-way connector i...

Abstract

The invention relates to the field of carriages, in particular to a carriage connecting piece and a carriage. The carriage connecting piece includes a connecting portion and inserting portions. The connecting portion is a tetrahedron, the connecting portion is a cuboid, and the interior of the connecting portion is provided with a cavity. The inserting portions are separately fixed to the same ends of the adjacent two mutually perpendicular side surfaces of the connecting portion. Each of the inserting portions is formed by two parallel inserting plates, and one ends of the inserting plates are fixedly connected with the side surfaces of the connecting portion. Glue grooves are formed in the side surfaces, in which no inserting portion is arranged, of the connection portion and the outer surfaces of the inserting plates. Through the arrangement of the glue grooves, sealants can be placed in the glue grooves, and the sealants bond a carriage profile to the carriage connecting piece. Through the carriage connecting piece, the carriage is manufactured by a cold working processing technology, and the welding processing method is avoided; and the machining is fast, the overall strengthof the carriage is stable, and the carrying capacity is guaranteed.
