Abstract
The utility model discloses a locomotive axle-hung box bearing removal load-bearing plate, which is used for removing a locomotive axle-hung box bearing. Pins are in clearance fit with via holes of an axle-hung box to be inserted into the holes of the axle-hung box; two pins and a mandril are uniformly distributed below a load-bearing plate in a three point way; a cushion block, a jack and a bearing jacking device are arranged at the central position of the load-bearing plate from bottom to top in sequence; the bearing jacking device is supported in the axle-hung box and is contacted with bearings through short pins; and the upper end face of the mandril and the upper generatrices of the pins are positioned on the same plane. The two pins are inserted into the via holes of the axle-hung box, and the two pins and the mandril form three points to support the load-bearing plate; the bearings at two ends of the axle-hung box are removed by only turning the axle-hung box once, bolts are not required to be assembled and disassembled, the pins are easily pulled out and inserted, and the whole process can be finished in 10 minutes; a condition that the bolts are assembled and disassembled and the axle-hung box is turned frequently can be avoided; and the locomotive axle-hung box bearing removal load-bearing plate is simple in structure and convenient to operate, travelling crane using time is short, the work efficiency can be effectively improved and the labor intensity of workers is reduced.
Description
Technical field
The utility model relates to railway locomotive disintegration dismounting special process equipment technology field, is a kind of frock that is used for locomotive axle suspension bearing box bearing removal specifically.
Background technology
Locomotive wheel in order to reach the requirement of flaw detection and maintenance, must disintegrate to axle suspension bearing box during to overhaul comprehensively.The axle suspension bearing box bearing is split type conical surface roller bearing, is the Railway Special product.When axletree and axle suspension bearing box decomposed, bearing inner race decomposed with axletree, and bearing outer ring places in the axle suspension bearing box seam.Axle-hang box is designed with and is uniformly distributed with three-flute below bearing outer ring, supplies to insert short pin dismounting bearing and uses.When the dismounting bearing outer ring, jack acts on the apical axis bearing apparatus below, moves upward through the short pin in the apical axis bearing apparatus, ejects bearing outer ring.Jack is the top upwards, must have a load dish to come supporting role power under it.At present, be to adopt the load dish to come supporting role power through the mode that bolt is connected in the axle suspension bearing box end.During the dismounting bearing, axle suspension bearing box was fallen, the load dish is connected on the axle-hang box end face with eight M12 bolts, then axle suspension bearing box is erected, and the load dish places under the axle suspension bearing box, puts cushion block, jack and apical axis bearing apparatus successively well, presses jack dismounting bearing; During dismounting other end bearing, need take out cushion block, jack and apical axis bearing apparatus successively, axle suspension bearing box was fallen; Pull down the load dish, again the load dish is connected in the other end of axle-hang box with eight M12 bolts, axle suspension bearing box is erected; Put into cushion block, jack and apical axis bearing apparatus, the dismounting bearing.After the completion, take out cushion block, jack and apical axis bearing apparatus, axle suspension bearing box was fallen pull down the load dish again.Dismounting diaxon commitments need 40 minutes, and driving can not be left basically.And the groundwork amount of dismounting bearing is installed and removed the load dish exactly, has that length consuming time, labor strength are big, the operating process trouble is complicated, take defectives such as the driving resource is many.
Summary of the invention
For overcoming the deficiency of prior art, the goal of the invention of the utility model is to provide a kind of locomotive to embrace
Axle box bearing dismounting load dish to reduce labor intensity, is increased work efficiency.
For realizing above-mentioned purpose; The via hole matched in clearance is inserted in the hole of axle suspension bearing box on pin of the utility model and the axle-hang box; Two pins and 3 of push rods are distributed under the load dish; Cushion block, jack, apical axis bearing apparatus place the center on the load dish successively from bottom to up, and the apical axis bearing apparatus is supported in the axle suspension bearing box and contacts with bearing through short pin, and the upper surface of push rod and the Up Highway UHW of pin are on same plane.
The utility model utilizes the via hole of axle suspension bearing box to insert two pins, adds a push rod again, constitutes supported at three point load dish, and dismounting axle suspension bearing box bearings at both ends only needs the once inside out axle suspension bearing box; Need not to install and remove bolt, light plug pin, whole process can be accomplished in 10 minutes; Can avoid installing and removing in a large number bolt, the upset axle suspension bearing box, simple in structure, easy to operate; Driving is very short service time, can effectively increase work efficiency, and alleviates labor strength.
Description of drawings
Fig. 1 is the structural representation sketch of the utility model.
The specific embodiment
Shown in accompanying drawing, push rod 1 directly stands up in the operation table top, and pin 2 is 1MM with the interporal lacuna excessively of axle suspension bearing box 8; Light plug pin 2; Two pins 2 and 1 three of push rods are distributed in the load dish 3 times that thickness is 15 MM band journal stirrup, and the Up Highway UHW of the upper surface of push rod 1 and pin 2 is on same plane, and 3 roughly are uniformly distributed with; Make load dish 3 levels, load dish 3 can carry the reaction force that jack 5 ejects bearing; The general jack of the cushion block 4 of transfer function power, 20T 5, apical axis bearing apparatus 6 place the center on the load dish 3 successively from bottom to up; Apical axis bearing apparatus 6 is supported in the axle suspension bearing box 8 through short pin 7 and contacts with bearing 9; Apical axis bearing apparatus 6 is a disk; Be uniformly distributed with three squares in circumference welding, have in the square circular hole, apical axis hold short pin 7 in circular hole slidably.
During the dismounting bearing, press jack 5, the last end face of jack 5 stretches out, and the short pin 7 in the apical axis bearing apparatus 6 moves up for 9 times at bearing with device, releases bearing 9; During dismounting other end bearing, take out whole device, upset axle suspension bearing box 8 repeats last action.The dismounting bearings at both ends only need be overturn axle suspension bearing box 8 once, can in 10 minutes, accomplish.
Claims (2)
1. locomotive axle suspension bearing box bearing removal load dish; It is characterized in that: pin (2) inserts in the axle suspension bearing box (8) with axle suspension bearing box (8) via hole matched in clearance; (1) three of two pins (2) and push rod are distributed under the load dish (3); Cushion block (4), jack (5), apical axis bearing apparatus (6) place the center on the load dish (3) successively from bottom to up, and apical axis bearing apparatus (6) is supported on axle suspension bearing box (8) and upward contacts with bearing (9) through short pin (7).
