Abstract

This invention relates to railway transport. The purpose of the invention is to increase the productivity and convenience of pressing out the pins. The device includes a housing 1, in the lower part of which there are stops 2, a sleeve 3, in the opening of which is installed and secured with screws 4 and two half-rings 5 a nut 6 with a steering wheel 7. A screw 8 passes through the nut, on the cylindrical surface 10 of which a ring I is installed with hinged grips 12. The ring 11 has the possibility of longitudinal movement along the screw 8 and is spring-loaded downwards by the elastic element 13. The magnitude of the force of the elastic element 13 is adjusted by an additional nut 9. The grips 12 are interconnected with a clamp m 14 by means of trunnions 20 rigidly fixed on the grippers 12 and placed in the slots 18 of the clamp 14, the longitudinal axes of which are angled, the top of which is directed towards the working parts 19 of the grips 12. The clamp 14 itself with its middle part is rigidly fixed at the end of the screw 8 and the outer surface is fixed against rotation by means of strips 15 fixed with screws 16 and placed in the vertical grooves 17 of the housing 1. The stops 2 are made in the form of corners and are intended for orientation of the device relative to the pin. 3 il. (L

c, the cylindrical surface 10 of the screw 8 passes through the ring 11, and the elastic element 13 is compressed. At the same time, fixing: torus 14, lowering together with screw 8 downwards, acts on grippers 12 due to interconnection of its inclined grooves 18 with housings 20 placed in them, divorce - grippers 12 to the sides. This occurs until the distance between the protrusions of the claws 12 becomes equal to the thickness of the wedge eye. After that, simultaneously with the movement of the screw 8, the working parts 19 of the grippers 12 under the action of the force of the compressed spring 13 begin to slide along the lateral planes of the wedge eyelet until the hinge is reached. The invention relates to railway transport, in particular to devices for removing the pins of passenger cars.

The purpose of the invention is to increase the productivity and convenience of pressing out the pins by automating the wedge capture process.

FIG. 1 shows the puller, general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. 1.Yo

The puller, for removing the pins, includes a housing 1, in the lower part of which there are stops 2, and in the upper part - a sleeve 3, in the opening of which is installed and secured with screws 4 and two half-wedges. At this moment, the working parts 19 of the rings 5 nut 6 with the steering wheel 7. Through the grip grips 12 under the action of the spring 13 and from ku 6 passes the screw 8, which is screwed on the interaction of the trunnions 20 with inclined additional nut 9. At the same time on vinteme 18 latch 14 instantly convergence, for 8 there is a smooth cylindrical section, thus ending the capture process. Rotation of the surface 10, on which the nut 6 is mounted in the opposite direction of co 11 with grippers 12, and between ring 11 20 the screw 8 is moved upwards, passing an elastic element 13 with and an additional nut 9. At the end of the screw 8 there is a fixed clamp 14, which is secured against rotation in the housing 1 by means of strips 15 attached to the retainer 14 25 with screws 16 and placed in the vertical grooves 17 of the housing 1. In addition, the retainer 14 also has grooves 18 whose longitudinal axes are at an angle to the longitudinal axis puller with apex, The direction to the working portions 19 the grippers 12 and the last 30 hingedly attached to it the grippers are made trunnion 20 arranged in grooves and a retainer, characterized in that in order to latch 18 14.povysheni performance and usability

The puller works as follows. Pressing out pins, on the screw is made

By turning the nut 6 with the aid of the handwheel - the section of the smooth cylindrical surface 7, the screw 8 rises upwards, the drive is mounted, on which the ring is set with the gripper in the initial position. After this tami, the puller is provided screwed on

this is m t force through the ring 11 and the grips 12 on the wedge. The latch 14 in this case does not allow the grippers 12 to disengage. The wedge is removed from the hole.

Claims (1)

Invention Formula Puller for pressing out pins, comprising a housing with stops, a nut with a steering wheel mounted on the screw, a ring with the device is lowered into the oil can (channel) up to the stop in the metal sheet of the car frame, and the body 1 is oriented relative to the half-folding heads by means of the stops 2. By turning the nut 6 in the opposite direction, the screw 8 goes down, the claws 12 come in contact with the earthing of the wedge. When the screw 8 is further lowered, the movement of the ring 11 downwards stops the additional nut and the elastic element placed between it and the ring, and the clamp is fixed at the screw end, the latter is fixed from turning in the housing and has grooves whose longitudinal axes are angled to the longitudinal axis the puller with the tip directed towards the working parts of the grippers, and on the grips the spigots arranged in the slots of the retainer are made. c, the cylindrical surface 10 of the screw 8 passes through the ring 11, and the elastic element 13 is compressed. At the same time, fixing: torus 14, lowering together with screw 8 downwards, acts on grippers 12 due to interconnection of its inclined grooves 18 with housings 20 placed in them, divorce - grippers 12 to the sides. This occurs until the distance between the protrusions of the claws 12 becomes equal to the thickness of the wedge eye. After that, simultaneously with the movement of the screw 8, the working parts 19 of the grippers 12 under the action of the force of the compressed spring 13 begin to slide along the lateral planes of the wedge eyelet until they reach the opening of the wedge. At this moment, the working parts 19 of the grippers 12 under the action of the spring 13 and from the interaction of the trunnions 20 with the inclined, thereby terminating, the capture process. By rotating the nut 6 in the opposite direction, the screw 8 is moved upwards, transmitting, with the clamps attached to it, a lock, characterized in that, in order to increase productivity and convenience this is m t force through the ring 11 and the grips 12 on the wedge. The latch 14 in this case does not allow the grippers 12 to disengage. The wedge is removed from the hole. Invention Formula Puller for pressing out pins, comprising a housing with stops, a nut with a steering wheel mounted on the screw, a ring with additionally a nut and an elastic element placed between it and the ring, and at the end of the screw a clamp is rigidly fixed, the latter is fixed against rotation in the housing and has grooves, the longitudinal axes of which are angled to the longitudinal axis of the stripper with the tip directed to the working parts grips, and on the grips are made pins, placed in the slots of the clamp.
