Description

A kind of automobile spandrel girder

Technical field

The utility model is related to a kind of automobile spandrel girders.

Background technology

Mass transit vehicle, the bottom of wagon box form the mainly spandrel girder of support, are commonly called as automotive frame, but existing This load-bearing Liangqi in technology is welding structure, and entire firmness is poor, and solder joint easily loosens during jolting, and is caused each The independent stress of component, be easy to cause bending, support is caused to be failed, there are more serious security risks.

Based on the above problem, it is desirable to provide a kind of bonding strength is larger, and it is more balanced to overally support ability, Ke Yiyou Effect increases the automobile spandrel girder of loading safety.

Invention content

The technical problem to be solved by the utility model is to provide a kind of bonding strength is larger, and overally support ability compared with For equilibrium, the automobile spandrel girder of loading safety can be effectively increased.

The utility model is achieved through the following technical solutions：

A kind of automobile spandrel girder, including two in the forward and backward girder being arranged in parallel, the girder is " mouth " font, two Offer square hole on the opposite face of the girder, square hole is provided with multiple, and tie-beam, institute are combined between two girders State the inner wall that the girder is resisted after tie-beam is inserted into the square hole, the joint place argon arc welding of the tie-beam and square hole Fixed, the tie-beam is I-shaped beam, and the side of the tie-beam offers a through-hole, welded between two girders It connects and is provided with a baffle, which is located at the leftward position of leftmost side tie-beam, is welded on the opposite face of the girder One extension board is welded with screw rod on the right side of the extension board, is combined with first baffle between two pieces of extension boards, and described One baffle has across the hole of the screw rod, and the screw rod is combined with a nut after passing through first baffle, in the more companies Connect and circular steel pipe be combined between beam, the steel pipe passes through the through-hole, and the steel pipe agrees with the through-hole, the baffle and The first baffle is limited respectively at the both ends of the steel pipe.

Preferably, after the tie-beam is inserted into via square hole in the girder, the upper and lower surface of the tie-beam and institute The gap that a 2cm-4cm is formed between the inner wall of girder is stated, rectangular steel bar, the steel bar are built-in at the interstitial site For solid construction, the both ends of the steel bar are flushed with the both ends of the girder, are welded and fixed between the steel bar and the girder, The gap between tie-beam and girder can be formed by steel bar to support so that girder can give the strength transmitting portions of load-bearing Tie-beam is shared, and reduces the deformation probability of girder.

Preferably, the baffle has the stop pad for being bonded the steel pipe, and the stop pad is rubber material.

Preferably, the first baffle has the first stop pad of fitting steel pipe, and first stop pad is also rubber Material, during the nut tightening, the first baffle moves to the left, the steel pipe of the first stop pad compressing at this time, and first Stop pad is fitted close after deforming upon between steel pipe.

Preferably, welding is provided with arc bracing piece between two girders, and the arc bracing piece circular arc is upward Protrusion can be supported at the bottom centre position of wagon box by arc bracing piece, increase enabling capabilities.

Preferably, it welds to be provided at the inside of the tie-beam, the left and right side position positioned at the through-hole and add The reinforcing plate of strong ties beam bending strength, the reinforcing plate has the first through hole being coaxially disposed with through-hole, due to opening up through-hole, Therefore structural strength of the tie-beam at lead to the hole site declines, and at this time by installing reinforcing plate, can increase anti-at the position Curved intensity.

The present apparatus when in use, in the case of being not inserted into steel pipe, is the nominal load weight of vehicle joined together, works as insertion During steel pipe, the nominal load weight of vehicle is promoted, and the amount promoted depends on the wall thickness of steel pipe, when steel pipe is solid, is increased The load-carrying weight added is promoted to maximum；It is however noted that support of the design of steel pipe just for the sake of the increase present apparatus Rigidity, therefore the nominal load tonnage of vehicle mark should not be promoted, if the nominal load tonnage of vehicle is promoted, steel pipe peace Dress is lost Protection significance.

The beneficial effects of the utility model are：The present apparatus realizes the support of wagon box by girder mating connection beam, completes master The purpose of weighing wanted, while steel pipe is assigned in activity, can be promoted the ability of load-carrying and the anti-deformation of the present apparatus, be avoided due to metal Accident occurs caused by fatigue, and steel pipe is interchangeable, and the review time of steel pipe is an inspection in 6-12 months, and steel is found when checking For pipe there are during deformation, needing to replace in time, the present apparatus can effectively promote loading safety, improve the safety of road transport, this The structure of device is relatively simple, and cost is more cheap, is suitble to promote the use of.
