Abstract
The utility model belongs to the technical field of locomotives, and mainly relates to a disassembling tool of a locomotive bogie blind hole crank arm pin. The disassembling tool of the locomotive bogie blind hole crank arm pin comprises a bolt (1), a sleeve (2) and a disk (3), wherein the bolt (1) is welded with the blind hole crank arm pin (5) needing disassembling; the sleeve (2) and the disk (3) are sleeved on the bolt (1) and are tightened through a nut (4); the disk (3) is located on the upper portion of the sleeve (2); the disassembling tool further comprises a wrench (7) and a sledge hammer; and the wrench (7) is matched with the nut (4). According to the disassembling tool of the locomotive bogie blind hole crank arm pin, the disassembling of the blind hole crank arm pin can be easy, convenient and fast to complete, and the problems that in the prior art, in the disassembling process of the blind hole crank arm pin, damage to a crank arm and to a crank arm hole in a locomotive bogie easily occurs are resolved.
Description
Technical field
The utility model disassembling technology belongs to the disassembling technology field of locomotive, relates generally to a kind of frock of disassembling of engine truck blind hole connecting lever pin.
Background technology
In the prior art, electric locomotive SS4, the SS7 of maintenance, SS8, SS9 bogie connecting lever pin top all are designed with connecting lever pin dismounting hole, by the dismounting hole connecting lever pin are pulled down when disassembling; But the SS3 engine truck is designed to blind hole connecting lever pin, does not design the dismounting hole, and in disassembling process, it is dead and grind platform circle often to run into connecting lever pin rust, when normally disassembling with not borrowing external force and time-consumingly difficultly can not effectively dismantling.Once adopted before this two kinds of method for dismounting, (1) adopts acetylene cutting, (connecting lever pin size ￠ 80*200).With acetylene torch the connecting lever pin is melted from the bogie pin-and-hole, need 2-3 hour, consume 1 bottle of acetylene of 2 bottles of oxygen.Also need bogie is put specific position, the cutting difficulty is large, and labour intensity is large.Fragile connecting lever, and framework connecting lever pin-and-hole cause to damage to enlarge; (2) integral cutting method is fallen bogie traction seat integral cutting, with hydraulic press the connecting lever pin is extruded, and traction seat is re-assemblied through polishing, line, positioning welding again.
The utility model content
The purpose of this utility model is the frock of disassembling that proposes a kind of engine truck blind hole connecting lever pin, can be easily, disassemble easily, to overcome existing technical problem in original the disassembling.
The utility model adopts following technical scheme for finishing above-mentioned purpose:
A kind of engine truck blind hole connecting lever pin disassemble frock, the described frock of disassembling includes bolt, sleeve and disk; The blind hole connecting lever pin welding of described bolt and required dismounting; Described sleeve, disk are nested with on bolt and are standby tight by nut; Described disk is positioned at the top of sleeve; The described frock of disassembling also includes wrench and sledgehammer; Described spanner cooperates with described nut.
A kind of engine truck blind hole connecting lever pin that the utility model proposes disassemble frock, adopt technique scheme, can finish easily, easily disassembling of blind hole connecting lever pin, solve in the prior art problem in connecting lever hole on the fragile connecting lever and engine truck of disassembling in the process at blind hole connecting lever pin.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the top view that the utility model uses state.
Among the figure: 1, bolt, 2, sleeve, 3, disk, 4, nut, 5, blind hole connecting lever pin, 6, the connecting lever cover, 7, spanner.
The specific embodiment
With specific embodiment the utility model disassembling technology is illustrated by reference to the accompanying drawings:
As shown in Figure 1, a kind of engine truck blind hole connecting lever pin disassemble frock, the described frock of disassembling includes bolt 1, sleeve 2 and disk 3; Described bolt 1 welds with the blind hole connecting lever pin 5 of required dismounting; Described sleeve 2, disk 3 are nested with on bolt 1 and are standby tight by nut 4; Described disk 3 is positioned at the top of sleeve 2; The described frock of disassembling also includes wrench 7 and sledgehammer; Described spanner 7 cooperates with described nut 4.
In conjunction with Fig. 2, the utility model with the bottom centre position of bolt full weld to blind hole connecting lever pin 5, checks firm welding first in use, waits obviously crackle of the rear nothing of cooling; Again sleeve 2 is nested with and arrives blind hole connecting lever pin 5 bottoms, and check that the gap is suitable, be set to disk 3 on the bolt 1 and before fastening nut 4 disassembles, first with the spirit of connecting lever pin spray foot pine rust, add sleeve 2 with spanner 7 and pull nut 4, twist when motionless at nut 4, knock disk with sledgehammer, nutting 4 while striking, the pulling force that makes progress that produces after the strain that blind hole connecting lever pin 5 is given a shock and makes progress, make blind hole connecting lever shank gradually on move, repeat to turn nut, and knock rigid disc with sledgehammer.Just gradually the connecting lever pin is pulled out from the connecting lever cover, can realize conveniently, disassemble easily.
Claims (1)
- An engine truck blind hole connecting lever pin disassemble frock, it is characterized in that: the described frock of disassembling includes bolt (1), sleeve (2) and disk (3); Described bolt (1) welds with the blind hole connecting lever pin (5) of required dismounting; Described sleeve (2), disk (3) are nested with upper at bolt (1) and standby tight by nut (4); Described disk (3) is positioned at the top of sleeve (2); The described frock of disassembling also includes wrench (7) and sledgehammer; Described spanner (7) cooperates with described nut (4).
