Abstract
The utility model relates to a subway engineering maintenance vehicle sleeper beam, comprising an upper cover plate, a lower cover plate, two side vertical plates and box ribbed plates which are installed and welded into a box. A U-shaped beam is fixed in the middle of the upper cover plate and is in butting joint with rest U-shaped middle longitudinal beams on a chassis of a vehicle body, two ends of the U-shaped beam are fixedly connected with edge beams of the chassis of the vehicle body, two ends of the upper cover plate are provided with barrels, bases, the transverse rib plates and the longitudinal rib plates are disposed in the barrels to form two spring seats, and threaded holes are arranged on outer sides of the lower cover plate on the two side vertical plates. The subway engineering maintenance vehicle sleeper beam is simple in structure, and a traction seat mounted under the sleeper beam not only can support the vehicle body but has functions of a traction beam. The lower cover plate is wider than the upper cover plate, and bolts for mounting the traction seat are exposed out of the outer sides of the side vertical plates of the sleeper beam, thereby bringing convenience to installation. A traction rod is omitted, and a bogie directly transmits traction force to the chassis of the vehicle body through the sleeper beam.
Description
Technical field
The utility model relates to a kind of track engineering car, is specifically related to subway engineering maintenance cart sleeper beam.
Background technology
Sleeper beam is a crucial load bearing component in rolling stock's car body underframe.The primary effect of sleeper beam is to bear vertical load, and car load two is that the above weight of spring all is delivered to bogie truck by sleeper beam.Bogie truck draws and will realize by draw bar car body, by draw bar tractive force is passed on the traction seat that is installed in end draw beam or side bar below, thereby realizes the route transmission of tractive force along bogie truck, draw bar, locomotive car body, vehicle.Adopt this tractive force transfer mode can make sleeper beam mainly bear the vertical force effect, longitudinal traction advocates to be transmitted by draw beam, underframe side bar (car that has also has intermediate longitudinal girder), therefore is suitable for high speed, heavy loading locomotive.The subway engineering maintenance cart is the low speed locomotive, and tractive force is little, can simplify the tractive force transfer route of locomotive, and the cancellation draw bar realizes that tractive force is directly by the transmission of bogie truck to the car body sleeper beam.Chinese patent ZL 200620069985.4 " the novel sleeper beam of railcar " adopts the sleeper beam middle part recessed, reserves enough spaces of pass through for wire casing and brake piping, must not punch on sleeper beam, is convenient to realize that the car of electric wiring and brake piping is assembled down in advance at the bottom of the car; The sleeper beam two ends connect by riveted joint with the underframe side bar; Leave the gap between sleeper beam and the underframe floor, this sleeper beam can only bear vertical load, also inconvenience is installed, the cost height.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned existing problem, simplifies the transmission link of tractive force in the subway engineering maintenance cart, and subway engineering maintenance cart sleeper beam a kind of simple in structure, easy for installation is provided.
The utility model comprises that upper cover plate, lower cover, vertical plates on both sides, casing gusset and assembly welding become box-shaped, is characterized in that: described upper cover plate middle part is fixed with the U-shaped beam, docks with all the other U-shaped intermediate longitudinal girders of car body underframe, captives joint with car body underframe side bar in two ends; The upper cover plate two ends are provided with and are provided with the secondary spring seat that base, horizontal bar plate and vertical gusset are formed in cylinder, the cylinder; The outside that described lower cover is positioned at vertical plates on both sides has tapped bore; Described lower cover width is greater than upper cover plate.
In order to realize this purpose better, in the box-shaped that becomes by upper cover plate, lower cover, cant board, casing gusset assembly welding, be fixed with cable-through hole.
The utility model is simple in structure, and traction seat is installed below sleeper beam, not only can play a part to support car body, plays the traction beam action simultaneously.Lower cover is wideer than upper cover plate, and the bolt that traction seat is installed exposes to the outside of sleeper beam cant board, and is easy for installation.Cancelled draw bar, bogie truck directly by sleeper beam to car body underframe transmitting tractive power.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the B-B cutaway view of Fig. 1.
Fig. 3 is the front view of upper cover plate.
Fig. 4 is the A-A cutaway view of Fig. 3.
Among the figure: 1, upper cover plate, 2, lower cover, 3, cant board, 4, the casing gusset, 5, cable-through hole, 6, the U-shaped beam, 7, cylinder, 8, base, 9, the horizontal bar plate, 10, vertical gusset.
The specific embodiment
As shown above, the box-shaped subway engineering maintenance cart sleeper beam that forms by assembly weldings such as upper cover plate 1, lower cover 2, vertical plates on both sides 3, casing gusset 4 and cable-through holes 5.Wherein upper cover plate 1 middle part is fixed with U-shaped beam 6, and all the other U-shaped intermediate longitudinal girders of U-shaped beam 6 and car body underframe dock, and captives joint with car body underframe side bar in two ends.The underframe central sill can be shunted a part well from the tractive force that sleeper beam passes over like this, reduces moment of flexure and shearing that tractive force causes in sleeper beam.
