Embodiment Construction

[0019] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention but not to limit the scope of the present invention.

[0020] figure 1 It is a schematic diagram of the structure of the present invention. It can be seen from the accompanying drawings that the present invention is a hanging structure for heavy equipment, which includes two opposite hanging beams 1, and each of the hanging beams 1 is set at both ends There are lug plates 3 , and several connecting plates 2 are arranged on opposite sides of the two hanging beams 1 , and each connecting plate 2 passes through the corresponding hanging beam 1 transversely. The hanging beam 1 is attached to one side of the heavy equipment 11 , the connecting plate 2 is connected and fixed with the heavy equipment 11 , and is connected and fixed with the...

Abstract

A suspended structure for heavy equipment comprises two suspended cross beams which are arranged oppositely, the two ends of each suspended cross beam are both provided with a lifting lug plate, each lifting lug plate is provided with multiple lifting lug holes, the faces, opposite to each other, of the two suspended cross beams are both provided with multiple connecting plates, each connecting plate is provided with a connecting hole, and each connecting plate is provided with multiple reinforcing ribs connected to the corresponding suspended cross beam. According to the suspended structure for the heavy equipment, the connecting plates penetrate through the suspended cross beams, the contact stress of the connecting plates and the suspended cross beams is dispersed, and the range of the force capable of being borne by the connecting plates is enlarged; by means of the reinforcing ribs, the functions of protection, support and deformation avoiding on the connecting plates are achieved, vertical plates are connected with the lifting lug faces and the welding faces, and angular variations of the lifting lug faces and the welding faces are avoided.

Description

technical field [0001] The invention relates to a suspension structure for heavy equipment, which belongs to the field of rail vehicle body design. Background technique [0002] At present, there are some shortcomings in the suspension beam of the underframe equipment of urban rail transit vehicles: when the suspension equipment is heavy, the beam rigidity is insufficient and the vibration amplitude is large; when the train impacts, cracks are prone to appear in the stress concentration area, and the risk of fracture increases. Starting from the above risk points, the present invention makes full use of the structural characteristics of the hanging beams, and effectively avoids the occurrence of risks through ingenious design. Contents of the invention [0003] In order to solve the above existing problems, the present invention discloses a hanging structure for heavy equipment, and its specific technical scheme is as follows: [0004] A suspension structure for heavy equ...
