Abstract
The utility model discloses a dual-purpose pulling claw which comprises a claw head and two pulling arms (4) connected with the claw head, wherein the upper part and the lower part of the claw head are respectively used for disassembling an RD type claw head (1) of an RD type bearing and an RE type claw head (3) of an RE type bearing, and the backs of the two claw heads are connected; both side faces in the middle of the claw head are provided with a hole (2) and two positioning bolts (6), and the two positioning bolts (6) are respectively and symmetrically arranged above and below the hole (2); the side faces of the RD type claw head (1) and the RE type claw head (3) are respectively provided with a through hole (5); one end of each pulling arm (4) is fixedly connected with a rotating shaft (7) matched with the hole (2) of the claw head, and one end of each pulling arm (4) is also provided with a bolt through hole (8) and a pin hole (9) which are matched with the positions and the sizes of the claw head positioning bolts (6) and the through hole (5); and a pin shaft (10) is arranged in the pin hole (9). The pulling claw does not need to be replaced during disassembling the two bearings, thus the dual-purpose pulling claw has convenient work and high efficiency.
Description
Technical field
The utility model relates to a kind of pulling claw of rolling stock rolling bearing dismounting machine.
Background technology
At present railway vehicle wheel is when repairing, and will move back from axletree needs maintenance or the rolling bearing scrapped and unload down.General adopt fixed rolling bearing dismounting machine to finish, railway axle is the most frequently used two kinds of axle types, i.e. RD and RE type, because the backstop size of two kinds of bearings differs bigger, will move back with different pulling claws and unload corresponding bearing, it is very inconvenient to change pulling claw work, wastes time and energy.
The utility model content
The purpose of this utility model solves dismounting RD exactly and the RE profile shaft holds because of changing the pulling claw inconvenience, and time-consuming inefficient problem provides a kind of dual-purpose pulling claw.
The technical solution adopted in the utility model is: dual-purpose pulling claw, it comprises pawl head and two torque arm that are connected with the pawl head, it is characterized in that described pawl head is respectively up and down is used for dismantling RD type pawl head and the RE type pawl head that RD type and RE profile shaft hold, the two pawl head rests back of the body links to each other, the middle two sides of pawl head are provided with hole and two bolts, two bolts be symmetrically distributed in respectively hole about, RD type pawl head and RE type pawl head side are respectively equipped with through hole; Described torque arm one end is connected with and the suitable rotating shaft of pawl head hole, and torque arm one end also is provided with and pawl head bolt and lead to the hole site and suitable bolt hole and the pin-and-hole of size, is provided with bearing pin in the pin-and-hole.
Adopt technique scheme, when needs dismounting RD profile shaft holds, Open Side Down is sleeved on that torque arm and pawl head link together on the bearing RD type pawl head, the rotating shaft of torque arm is inserted in the hole of pawl head side, the bolt of pawl head places in the bolt hole of torque arm, inserts bearing pin in pin-and-hole and the through hole, the starting drive unit, torque arm is held the RD profile shaft and is held, and can disassemble bearing from axle; When needs dismounting RE profile shaft holds, unload lower bearing pin and bolt, the rotary pawl head repeats above-mentioned action, can hold the RE profile shaft and dismantle.
In sum, the beneficial effects of the utility model are: dismantled but also can hold the RE profile shaft and dismantle because the utility model not only can hold the RD profile shaft, so the utility model function is many; Need not change pulling claw when two kinds of bearings of dismounting, therefore work is convenient, the efficient height.
