The specific embodiment:
Below in conjunction with accompanying drawing the present invention is done explanation further.
As illustrated in fig. 1 and 2, a kind of railcar hitch bolt of the present invention comprises that with the high pulling torque charger loading gripper shoe 1, square steel beam 2, load load mainboard 3 and fixed head 4.Said loading gripper shoe 1 is fixed on the car body undercarriage bea 5 through fixed head 4; Said load loads the side that mainboard 3 is arranged at hitch set bolt mount pad 6; The thickness that load loads mainboard 3 is 10mm; Load the main bearing holes 301 that is provided with 55 * 26.5mm on the mainboard 3 in load, the force-transmitting block of 25.4 * 25.4mm on the reaction arm of force of main bearing holes 301 and torsion multiplier is complementary, and the two ends of said square steel beam 2 load mainboard 3 with loading gripper shoe 1 and load respectively and weld together.
Shown in Fig. 1 to 6; Load gripper shoe 1 and comprise first plate body 101 that is positioned at car body undercarriage bea 5 bottom surfaces; Be welded with bar shaped carrier block 102 on said first plate body 101; Said bar shaped carrier block 102 is suitable with the waist-shaped hole 501 on the car body undercarriage bea 5, and said waist-shaped hole 501 adopts existing waist type installing hole on the car body undercarriage bea 5, and the effect of these waist type installing holes is convenient other parts of on floor underframe for vehicle, installing.Bar shaped carrier block 102 inserts in the waist-shaped hole 501, is 75mm in the spacing that is equipped with on the bar shaped carrier block 102 between first screwed hole, 103, the first screwed holes 103 of three M16.Said fixed head 4 comprises second plate body 401 that is positioned at car body undercarriage bea 5 surfaces; The through hole 402 that it is 20mm that said second plate body 401 is provided with first screwed hole, 103 corresponding three diameters; Be provided with first bolt 402 of M16 in the said through hole 402, fixing through first bolt 402 being screwed in first screwed hole, the 103 interior gripper shoes 1 that will load with car body undercarriage bea 5.
It is more stable for loading gripper shoe 1 is supported; Be welded with the 3rd plate body 404 on said second plate body 401; Said the 3rd plate body 404 and second plate body 401 are cross-shaped, and the centre-to-centre spacing that is provided with between 405, two second screwed holes 405 of M16 second screwed hole at the two ends of the 3rd plate body 404 is 200mm; The screw rod end that screws in second bolt, 406, the second bolts 406 in second screwed hole 405 contacts on the car body undercarriage bea 5.
For the painted surface that prevents car body undercarriage bea 5 and first plate body 101 and second plate body 401 collide with impairedly, between said first plate body 101 and car body undercarriage bea 5 bottom surfaces, and all be equipped with nylon sheet 7 between second plate body 401 and car body undercarriage bea 5 bottom surfaces.
Like Fig. 1, shown in 2 and 7; In order to prevent that the torsion multiplier from rocking, influence is executed and is carried, and load loads on the mainboard 3 and also is provided with two support arm holes 302; The effect in support arm hole 302 is fixing support arms on the torsion multiplier, and then makes torsion multiplier and load load mainboard 3 to be fixed together.
In addition; Railcar hitch bolt of the present invention also comprises support backstay 8 with the high pulling torque charger; Said support backstay 8 vertically is welded on the end that load loads mainboard 3; Support the side of backstay 8 and the side of hitch set bolt mount pad 6 and fit, end and car body undercarriage bea 5 bottom surfaces of supporting backstay 8 fit.Support 8 pairs of load loadings of backstay mainboard and play auxiliary support positioning action, guarantee to keep because of using the required space distance of torsion multiplier between load loading mainboard 3 and the car body undercarriage bea 5.
Same; For the painted surface that prevents hitch set bolt mount pad 6 and car body undercarriage bea 5 collides with impaired with support backstay 8; Between the side of the side of said support backstay 8 and hitch set bolt mount pad 6, and be equipped with nylon block 9 between the end of support backstay 8 and car body undercarriage bea 5 bottom surfaces.
Shown in Fig. 8 and 9, said square steel beam 2 is four bar shaped steel plate 201 assembly weldings square tubes together.Having spacing on two relative bar steel plates 201 therein is the lightening hole 202 of 30mm for the 35mm diameter, easily installs to reduce operating personnel's application of force and convenient.
To railcar hitch bolt 10 fixedly the time; Need be with two chargers of the present invention; The both sides that is arranged on hitch set bolt mount pad 6 that one the first from left is right uses this charger that the railcar hitch bolt 10 of the and arranged on left and right sides on the hitch set bolt mount pad 6 is installed and fixed respectively.
When the loading gripper shoe of this charger 1 through bolt and car body undercarriage bea 5 bottom surfaces fixedly the time; The load of this charger loads the side that mainboard 3 can just in time be positioned at hitch set bolt mount pad 6; Force-transmitting block on the reaction arm of force of torsion multiplier just in time can be contained in load and load in the main bearing holes 301 of mainboard 3; The reaction arm of force that is torque multiplier has had the strong point; Simultaneously the torsion multiplier is loaded mainboard 3 through support arm hole 302 and load and be fixed together, operating personnel just can be convenient to use torque multiplier.The bar shaped carrier block 102 that loads on the gripper shoe 1 plays the effect of offsetting torque spanner moment; After second bolt 406 on the 3rd plate body 404 is conflicted with car body undercarriage bea 5; Play auxiliary effect of sharing moment, make the whole charger must not slippage when the torsion multiplier loads.
Railcar hitch bolt of the present invention is the device that the loaded load of railcar hitch bolt 10 is transferred to car body undercarriage bea 5 by torque multiplier with the high pulling torque charger; When the plane, place, oval hole of the fixed pan of subway vehicle hitch bolt 10 and car body undercarriage bea 5 was not parallel, square steel beam 2 also can be made into to the crooked square tube of different directions.
The above only is a preferred implementation of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; Can also make some improvement and retouching, these improvement and retouching also should be regarded as protection scope of the present invention.
