Abstract
The utility model relates to the technical field of diesel locomotive test equipment, in particular to a diesel locomotive bench test connecting device. The diesel locomotive bench test connecting device comprises a hook body, a conjoining body, a joint, and a connecting seat. The hook body is located in the front end of the conjoining body. The joint and the connecting seat are located in the rear end of the conjoining body. The connecting device is a rigid structure. The connecting seat is fixed on a locomotive, and the hook body is connected with a testing stand. When a locomotive bench test is conducted, a traction force and a braking force can be rigidly transmitted to a measuring system of a testing stand traction and positioning device; measurement errors and correction computation caused by elastic connection can be prevented; and a traction characteristic curve and a resistive braking characteristic curve of the locomotive can be drawn accurately, thereby realizing the object of the locomotive bench test.
Description
Technical field
The utility model relates to diesel locomotive testing equipment technical field, especially a kind of diesel locomotive bench test coupling arrangement.
Background technology
The SDD7 type locomotive is the broad gauge locomotive, can't carry out road test, need carry out bench test, so that whether checking locomotive tractive characteristic etc. meets designing requirement, and each parts are carried out to post-installation review, and this locomotive coupler adopts the chain hitch, the one, can't be connected with rolling rig draw-gear hitch, the 2nd, former coupling arrangement is that elasticity connects, can't the Measurement accuracy hauling capacity of a locomotive and damping force when bench test, and test can not be produced a desired effect.
The utility model content
Connect inconvenience in order to overcome existing broad gauge locomotive test, the deficiency of impact test accuracy, the utility model provides a kind of diesel locomotive bench test coupling arrangement.
The utility model solves the technical scheme that its technical matters adopts: a kind of diesel locomotive bench test coupling arrangement, comprise coupler body, conjuncted, connector and Connection Block, and coupler body is positioned at conjuncted front end, and connector and Connection Block are positioned at conjuncted rear end.
According to another embodiment of the present utility model, further comprising conjuncted is box structure, and two ends all are provided with pin-and-hole.
According to another embodiment of the present utility model, further comprise that coupler body is connected with conjuncted by cotter pilotage and front pin.
According to another embodiment of the present utility model, further comprise that connector is pin-shaped, is embedded in Connection Block.
According to another embodiment of the present utility model, further comprise that connector and Connection Block are connected with conjuncted by end pin.
According to another embodiment of the present utility model, further comprise that the two ends cover of end pin has pad.
The beneficial effects of the utility model are, this coupling arrangement is rigid structure, Connection Block is fixed on locomotive, coupler body is connected with testing table, when the locomotive bench test, tractive force and damping force rigid of transmission can be drawn to the measuring system of locating device to testing table, avoid causing error and the corrected Calculation in measurement because elasticity connects, accurately draw locomotive tractive characteristic curve and resistive braking family curve, reach the purpose of locomotive bench test.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. coupler bodies in figure, 2. front pin, 3. cotter pilotage, 4. conjuncted, 5. connector, 6. pad, 7. end pin, 8. Connection Block.
Embodiment
As Fig. 1 is structural representation of the present utility model, a kind of diesel locomotive bench test coupling arrangement, comprise coupler body 1, conjuncted 4, connector 5 and Connection Block 8, and coupler body 1 is positioned at conjuncted 4 front end, and connector 5 and Connection Block 8 are positioned at conjuncted 4 rear end.Conjuncted 4 is box structure, and two ends all are provided with pin-and-hole.Coupler body 1 is connected with conjuncted 4 with front pin 2 by cotter pilotage 3.Connector 5 is pin-shaped, is embedded in Connection Block 8.Connector 5 is connected with conjuncted 4 by end pin 7 with Connection Block 8.The two ends cover of end pin 7 has pad 6.
One 60 * 60 square hole is arranged in the middle of Connection Block 8, and 60 * 60 shafts of connector 5, through square hole, make base and Connection Block 8 closely connected, chimeric being integral.With 4 M30 bolts, Connection Block 8 is arranged on the mount pad of locomotive car body, by end pin 7, by conjuncted 4, with connector 5, be connected, conjuncted 4 the other end is connected with coupler body 1 by cotter pilotage 3, split pin all is equipped with in end pin 7 and cotter pilotage 3 belows, with slip-off preventing, coupler body 1 is connected and is tested with the hitch of testing table traction locating device.
Conjuncted 4 box structures that are Plate Welding, maximum drawbar pull 420KN during according to the locomotive bench test when design, consider that safety coefficient 1.4 selects steel plate thickness, determines weld bead height, guaranteeing under the prerequisite of bulk strength perforate loss of weight on biside plate.Expense hole on 60 * 60 shafts of connector 5, the unitized construction of employing connector 5 and Connection Block 8, make the bulk strength of this coupling arrangement meet the tractive force of locomotive bench test and the requirement of damping force.
This coupling arrangement is rigid structure, Connection Block 8 is fixed on locomotive, coupler body 1 is connected with testing table, when the locomotive bench test, tractive force and damping force rigid of transmission can be drawn to the measuring system of locating device to testing table, avoid causing error and the corrected Calculation in measurement because elasticity connects, accurately draw locomotive tractive characteristic curve and resistive braking family curve, reach the purpose of locomotive bench test.
