Abstract
The utility model discloses a connection structure that is used for railway internal combustion crane double clutch, it is a connection structure that is used for railway internal combustion crane double clutch who makes the torsional spring fix a position the accuracy, including clamp plate, jack catch, torsional spring and inclined to one side hook bolt, seted up the bolt hole on the clamp plate, the hook bolt is installed in the bolt hole partially, the head of hook bolt is provided with the pinhole partially, the afterbody of jack catch is the U -shaped to the afterbody is provided with the pinhole, the U -shaped afterbody of jack catch cover is at the head of hook bolt partially and pass through the pin junction, partially the head of hook bolt is provided with convex stuck point, the salient direction of stuck point dorsad the jack catch and coaxial with the axis of jack catch, the head at the jack catch is connected to jump ring one end, and other end card is in stuck point department. Because the head at inclined to one side hook bolt is provided with convex stuck point, just consequently can fix it in stuck point department when the installation torsional spring, and hook bolt itself can not move partially, this makes the torsional spring change of position can not appear.
Description
Technical field
The utility model relates to a kind of connection structure, especially a kind of connection structure for railway internal combustion crane two-way clutch device.
Background technology
The main business of my company is special disposal blast-furnace metallurgical slag, and railway crane uses frequent, and is the very important equipment that is in whole production technique. The two-way clutch device of railway internal combustion crane is the parts that to be connected between engine and reduction box important, it is made up of three block pressur plates and two pieces of friction plates, by from different active friction plates in conjunction with time can realize the conversion function of spindle rotating direction, and can by being in separate stage, main shaft is stopped, to reach the object of brake. And partially head screw rod is the important part that three block pressur plates and two pieces of friction plates rise fixed action, owing to railway crane is in operation process, two-way clutch device needs high speed rotating, switching turns to, the bigger after vibration of gap wear is bigger, in addition railway Working environment is severe, the nut that screw rod in use plays fixed action can slowly loosen, cause excessive clearance, and can be worn and torn in screw hole by screw rod gradually that loosen, even causing screw rod to rupture, cannot well be combined between friction plate with pressing plate, two-way clutch device cannot normal operation.
Head screw rod also undertakes the function installing claw partially simultaneously, claw is rotatably arranged on inclined head bolt, and locked by torsion spring, torsion spring is mainly arranged on the joint pin of claw and inclined head bolt, owing in use joint pin can rotate, this just causes the position of torsion spring to change, and affects the elastic force that torsion spring applies.
Practical novel content
Technical problem to be solved in the utility model is to provide a kind of connection structure for railway internal combustion crane two-way clutch device making torsion spring accurate positioning.
The utility model solves the connection structure for railway internal combustion crane two-way clutch device that its technical problem adopts, and comprises pressing plate, claw, torsion spring and inclined head bolt; Having offered bolt hole on described pressing plate, described inclined head bolt is arranged in bolt hole; The head of described inclined head bolt is provided with pin-and-hole; The afterbody of described claw is U shape, and afterbody is provided with pin-and-hole; The U shape afterbody of claw is enclosed within the head of inclined head bolt and is connected by pin; The head of described inclined head bolt is provided with the stuck point of protrusion, the protrusion direction of the stuck point back of the body to claw and with the axis coaxle of claw; Described jump ring one end is connected to the head of claw, and the other end is stuck in stuck point place.
Further, described inclined head bolt adopts at least two nuts to be arranged on pressing plate.
Further, described claw, torsion spring and inclined head bolt are provided with three groups, and three groups of circumferential directions along pressing plate are evenly arranged.
The beneficial effects of the utility model are: owing to being provided with the stuck point of protrusion at the head of inclined head bolt, therefore stuck point place can be just fixed in when installing torsion spring, and head bolt itself can not move partially, this makes torsion spring to fix, and there will not be the change of position. Meanwhile, inclined head bolt adopts two nuts to install, and this makes its installation more firm, also can not loosen, extend the work-ing life of himself in long-term vibration.

Fig. 1 is structural representation of the present utility model;
Fig. 2 is the front view of inclined head bolt;
Fig. 3 is the left view of Fig. 2;
Fig. 4 is the scheme of installation of inclined head bolt;
Component, position and numbering in figure: pressing plate 1, claw 2, torsion spring 3, partially head bolt 4, stuck point 5, pin 6.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the utility model comprises pressing plate 1, claw 2, torsion spring 3 and inclined head bolt 4; Having offered bolt hole on described pressing plate 1, described inclined head bolt 4 is arranged in bolt hole; The head of described inclined head bolt 4 is provided with pin-and-hole, and the structure of inclined head bolt 4 is as shown in Figures 2 and 3; The afterbody of described claw 2 is U shape, and afterbody is provided with pin-and-hole; The U shape afterbody of claw 2 is enclosed within the head of inclined head bolt 4 and is connected by pin 6; The head of described inclined head bolt 4 is provided with the stuck point 5 of protrusion, the protrusion direction of stuck point 5 back of the body to claw 2 and with the axis coaxle of claw 2; Described jump ring one end is connected to the head of claw 2, and the other end is stuck in stuck point 5 place. Torsion spring 3 one end is pressed on claw 2, and the other end is inboardend, and inboardend is crushed on stuck point 5 times, and the annular collar of torsion spring 3 is enclosed within pin 6, thus locates and fix. It is belong to loose fit that the annular collar of torsion spring 3 is enclosed within pin 6, but under the effect of stuck point 5, torsion spring 3 can not be shifted one's position with vibration, thus avoids change in location.
More firm in order to make inclined head bolt 4 install, as shown in Figure 4, described inclined head bolt 4 adopts at least two nuts to be arranged on pressing plate 1. Inclined head bolt 4 needs to lengthen, so that its thread end can install the nut of two or more, it is more firm that so inclined head bolt 4 is arranged on pressing plate 1, can not loosen because of vibration.
Concrete, as shown in Figure 1, described claw 2, torsion spring 3 and inclined head bolt 4 are provided with three groups, and three groups of circumferential directions along pressing plate 1 are evenly arranged. Three groups of such structures can well realize the function of two-way clutch.
