Abstract
The utility model discloses a switch engine frame comprising a frame main body, wherein a traction cross beam is arranged on the frame main body, and a traction seat is arranged on the traction cross beam. The switch engine frame is simple in structure and reasonable in design, and can be conveniently dismounted when exceeding the height limitation during transportation, so that the height of the switch engine frame can be reduced to meet the height limitation requirement, the force transmission is relatively reasonable, and a traction point is low, so that the axial gravity of a locomotive can be favorable to be evenly distributed.
Description
Technical field
The utility model relates to a kind of vehicle frame on the locomotive, particularly relates to a kind of shunting locomotive vehicle frame.
Background technology
The shunting locomotive vehicle frame is the installation basis of locomotive top equipment, and it mainly plays a part to bear various impulsive forces in tractive force, braking force, the locomotive operation, therefore needs it to have enough strength and stiffness.Traditional shunting locomotive vehicle frame, dual mode is mainly adopted in the transmission of general tractive force: a kind of is to pass to the top car body by the drawing pull bar seat on the frame side member, another kind is to pass to the top car body by the centre of pull pin-and-hole on the vehicle frame longitudinal centerline, first kind of way is mainly used in common two axles, three axle truck, the towing point of the second way is too high, cause that easily the Locomotive Axle Load distribution is uneven, be mainly used in the low speed locomotive.For four-shaft steering, because bogie truck is higher, this dual mode is all improper, how to design a kind of shunting locomotive vehicle frame and can be beneficial to Locomotive Axle Load respectively evenly by reasonable reduction towing point, becomes this those skilled in the art's problem demanding prompt solution.
The utility model content
The purpose of this utility model just provides a kind of shunting locomotive vehicle frame, and surpassing limitation in height during transportation can be for convenience detach, highly meets the requirements thereby reduce, and the transmission of power is more reasonable, towing point is low, is conducive to the Locomotive Axle Load distributed uniform, can solve the problems of the technologies described above fully.
The purpose of this utility model realizes by following technical proposals:
A kind of shunting locomotive vehicle frame comprises main body of vehicle frame, and main body of vehicle frame is provided with the traction crossbeam, and described traction crossbeam is provided with traction seat.
Further, described traction seat is arranged on traction crossbeam lower central position, and the traction seat center is provided with pin-and-hole.
Further, described traction crossbeam comprises front haulage crossbeam and rear haulage crossbeam, and front haulage crossbeam bottom correspondence arranges the front haulage seat, and rear haulage crossbeam bottom correspondence arranges the rear haulage seat.
Further, described main body of vehicle frame front and rear correspondence is provided with front haulage motor ventilation road and rear haulage motor ventilation road.
Further, described forward and backward motor ventilation road all has a ventilation inlet and four air outlets.
This motor ventilation pipeline corresponding eight traction electric machines are set, be conducive to the heat radiation of traction electric machine.
Further, described main body of vehicle frame front-end and back-end are provided with upper end plate, the upper end plate lower end lower end plate that removably connects.
Traditional vehicle frame end plate is generally integral type, and this structure has overcome the non-detachable defective of traditional vehicle frame end plate, highly surpasses in the restriction in transportation, can dismantle very easily lower end plate.
Further, the junction of described upper end plate and lower end plate is provided with strengthening rib so that end plate junction, upper and lower part structure is more firm, and stressed property is better.
Compared with prior art, the beneficial effects of the utility model are:
Simple in structure, reasonable in design, surpassing limitation in height when transportation can be for convenience detach, highly meet the limit for height requirement thereby reduce, and the transmission of power is more reasonable, thus the low Locomotive Axle Load distributed uniform that is beneficial to of towing point.

The specific embodiment
Below in conjunction with specific embodiments and the drawings the utility model is further described.
As shown in Figures 1 to 4, a kind of shunting locomotive vehicle frame, comprise main body of vehicle frame 14, main body of vehicle frame 14 front and rear correspondences arrange front haulage crossbeam 1 and rear haulage crossbeam 2, forward and backward traction crossbeam 1,2 two ends all are symmetrically welded frame side member 13, front haulage crossbeam 1 lower central position arranges front haulage seat 3, and rear haulage crossbeam 2 lower central positions arrange rear haulage seat 4, and forward and backward traction seat 3,4 centers are provided with pin-and-hole 12.When being connected with bogie truck, forward and backward traction seat 3,4 adopts the bolt of 20 M36 to be connected with the traction seat of bogie truck separately.
As shown in figures 1 and 3, the corresponding traction electric machine of described main body of vehicle frame 14 front and rears is provided with forward and backward traction electric machine air flue, and forward and backward motor ventilation road is separately to having a forward and backward air flue ventilation inlet 7,8 and four forward and backward air flue air outlets 5,6.
As depicted in figs. 1 and 2, described main body of vehicle frame 14 front-end and back-end set firmly upper end plate 9, and upper end plate 9 lower ends removably connect by bolt and lower end plate 10.The junction of described upper end plate 9 and lower end plate 10 is provided with strengthening rib 11, so that upper and lower part end plate 9,10 junction structures are more firm, stressed property is better.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
