Description
Technical field
The invention belongs to railroad maintenance technical fields, and in particular to a kind of auxiliary device and side for railway ballast maintenance
Method.
Background technique
Railroad track, abbreviation rail, rail, track etc., be used for railway, and with railway switch cooperation, enable train without turn
To that just can walk, track is usually made of two parallel rail, and rail fixation is placed on sleeper, is cut under sleeper for road；With
Rail made of steel can bear bigger weight than other materials, and sleeper is also known as sleeper or road pillow, and function is rail
Weight separately spread, and rail is kept to fix, maintains the gauge of rail, it is however generally that, the bottom of track is what chad was paved into
Road quarrel, road quarrel are also known as ballast, rubble or railway roadbed, are to provide elasticity and drain function, rail for track to be layered on concrete
On the pedestal built up, or even inside concrete, railroad track must be repaired often to maintain good operating state.
When safeguarding rail, need to be corrected rail maintenance, and rail pedestal is then to have stone etc. more
Firm material mixing is laid with together made of, thus can only by after the railway roadbed of rail and surface separation can to rail into
Row fine tuning correction, and be more troublesome when being cut to rail railway roadbed using artificial removal, and inefficiency, and there is no assorted at present
The device for more efficiently cutting rail railway roadbed, so that the construction time of railroad maintenance engineering becomes longer, to railway operation
Cause influence.
Summary of the invention
The object of the invention is that solve the above-mentioned problems and to provide a kind of structure simple, design a kind of reasonable use
In the auxiliary device and method of railway ballast maintenance.
The present invention through the following technical solutions to achieve the above objectives:
A kind of auxiliary device for railway ballast maintenance, including the first traction mechanism interconnected and the second dragger
The motor section that structure, first traction mechanism and the second traction mechanism include tractive unit, is connected on tractive unit, the motor
Portion is equipped with cutting part, and the driving mechanism and cutting part inside the second traction mechanism are the prior art, can refer to patent
CN200620167888.9；
The cutting part includes bottom jib, the cutter chain being movably arranged in bottom jib, the vertical shaft in cutting part, is fixedly mounted
Pentacle weel in vertical shaft lower end；
The inside of the tractive unit is equipped with take-up mechanism, the steel cable being fixedly connected in take-up mechanism.
As a further optimization solution of the present invention, pass through connector activity between first traction mechanism and cutting part
Connection, second traction mechanism are fixedly connected by connector with cutting part, and connector can use connection bolt, but not only
It is limited to this, the direction of the motor section driving vertical shaft rotating in the first traction mechanism is identical as the vertical shaft in the second traction mechanism, makes
Can more quickly rail railway roadbed be cut under the action of dual power source by obtaining cutter chain.
As a further optimization solution of the present invention, first traction mechanism is to care for mechanism, and the mechanism of caring for consolidates
On bottom jib, the mechanism of caring for includes mounting plate, the screw hole on mounting plate, the extension being welded in the middle part of mounting plate for Dingan County
Mounting plate can be fixedly mounted on bottom jib, so by hook and the traction steel rope of cable being movably connected on hook by connection bolt
Afterwards by the fixed hook on a mounting board in one end of traction steel rope of cable, it is more convenient to install, and can ensure enough traction effects.
As a further optimization solution of the present invention, the length of the traction steel rope of cable is the length of the second traction mechanism and steel cable
The sum of degree, the traction steel rope of cable are connected with hoist engine far from one end of hook, and the length of steel cable can be according to Practical Project
The length of middle rail railway roadbed maintenance designs, and engineering can also be divided into multiple processes and operated, and hoist engine is the prior art,
The identical effect for shrinking steel cable can be played with the take-up mechanism in the second traction mechanism.
As a further optimization solution of the present invention, bearing there are two being set between the vertical shaft and cutting part, described first
Traction mechanism is identical as the direction of rotation of pentacle weel in the second traction mechanism, and the cutter chain in cutting part is run well
And guarantee certain cutting power, prevent the phenomenon of cutting force degree deficiency occur because cutter chain is too long, can make engineering into
Degree is unaffected.
A method of maintenance being corrected to rail railway roadbed using above-mentioned apparatus, comprising the following steps:
Step S1: timing is repaired to rail railway roadbed, is first drawn on rail railway roadbed and sets a perforation, then will do not connected
The bottom jib connect on the cutting part of the first traction mechanism passes through perforation；
Step S2: the cutting part for passing through perforation is connect with the first traction mechanism by connector, the first traction after connection
Pentacle weel in mechanism is engaged with cutter chain；
Step S3: pricking at the position of corresponding steel cable length and set up stake, and by the first traction mechanism and the second traction mechanism
On steel cable one end be connected in staking out；
Step S4: starting machine after, cutting part cuts rail railway roadbed under the driving of motor section, cutting it is same
When, the take-up mechanism in the first traction mechanism and the second traction mechanism will shrink steel cable and drive itself to be moved to the position of staking out
It is dynamic, by rail railway roadbed and surface separation in mobile process.
As the scheme that advanced optimizes of the above method, first traction mechanism is to care for mechanism, passes through perforation
Upper mounting plate is fixedly mounted on cutting part, traction steel rope of cable is flexibly connected with the hook on mounting plate, it is then that traction steel rope of cable is remote
One end from hook is connected in staking out.
As the scheme that advanced optimizes of the above method, the length of the traction steel rope of cable is steel cable and the second traction mechanism
The sum of length.
The beneficial effects of the present invention are:
1) present invention employs double-heading driving mechanism driving cutting parts to cut to rail railway roadbed, so that rail road
Bed quickly and surface separation can substantially reduce the time of construction, and reduce the waste of manpower, substantially reduce railway school
The construction time just safeguarded, and can guarantee that the stress of two traction mechanisms more balances, it is relatively stable；
2) present invention employs two kinds of forms of construction work, when the driving force of the second traction mechanism is enough, by the first dragger
Structure, which is replaced with, cares for mechanism, and installation connection is more convenient, and can equally ensure enough tractive force and counterbalance effect；
3) the configuration of the present invention is simple, stability is high, and design rationally, is easy to implement.
