Description
Technical field
The utility model relates to railway track maintenance of equipment, specifically a kind of eight pick of railway track makes maintenance dress firm by ramming
It sets.
Background technique
Tamping unit is on tamping car for making a kind of equipment between rail bilateral pillow with pillow bottom railway ballast firm by ramming.By smashing
Gu the railway ballast of rail two sides rests the head on bottom railway ballast compactness to improve, while with track lining device is closed, increasing the stability of track, disappearing
Except the deviation of directivity of track, left and right horizontal departure and forward and backward vertical deviation.
Domestic existing tamping unit mainly has two kinds: one is 32 pick tamping units of double pillows, and a set of tamping unit is by 2 sets
It makes unit composition firm by ramming, an eccentric shaft is installed on a tool frame, 8 sets of opening-closing driving devices are housed simultaneously on eccentric shaft, often
It covers opening-closing driving device and a set of tamping arm (see figure 1) is housed；Second is three pillows, 48 pick tamping unit, and a set of tamping unit is by 4
Set makes unit composition firm by ramming, and every set makes unit firm by ramming and is respectively arranged with 1 eccentric shaft and 6 sets of tamping arm (see figure 2)s.Above-mentioned railway track is made firm by ramming
Curing means has played positive effect in railway track maintenance；But above-mentioned railway track makes curing means firm by ramming, and there are still certain
Deficiency, its structure is complicated, cannot meet simultaneously and make curing requirements firm by ramming in main track and Cha Qu, for this reason, it is necessary to design a kind of symbol
Number railway track makes curing means firm by ramming.
Summary of the invention
The purpose of this utility model is that structure is complicated to overcome existing railway track to make curing means firm by ramming, cannot be expired simultaneously
Foot makes curing requirements firm by ramming main track and switch area, provides a kind of eight pick of railway track and makes curing means firm by ramming, the device is each inclined
2 tamping arms are only installed, 2 tamping arms are mounted with tamping pickaxe respectively, can meet simultaneously in main track and Cha Qu in mandrel
It makes curing requirements firm by ramming, alleviates the load of eccentric shaft, tamping pickaxe underthrust angle vertical reduces underthrust resistance in plane on rail；
To extend the service life of eccentric shaft；Improve the versatility of tamping unit itself components to the greatest extent simultaneously.
The technical solution of the utility model is: a kind of eight pick of railway track makes curing means firm by ramming, including rack, vertical (vertical) to
Guide post, eccentric shaft, tamping arm, opening and closing drive cylinder, hydraulic motor, laterally steering column and guide sleeve.
Eight pick of a kind of railway track makes curing means firm by ramming, is made of the identical unit of making firm by ramming of 4 structures, each smashes
Gu unit is equipped with a pair of of tamping arm, the tamping arm for being respectively provided with tamping pickaxe is mounted on one and is adjustable in the rack of height；Tamping arm
It is connected by opening and closing drive cylinder with an eccentric shaft.
Making firm by ramming lift cylinder is installed at the top of unit, makes unit eccentric shaft one end firm by ramming and hydraulic motor, liquid driving are installed
Hydraulic motor is to drive eccentric shaft turns.
The tamping arm, each tamping arm lower end are equipped with mounting hole, and tamping pickaxe installs the mounting hole of fixed tamping arm lower end
It is interior.
Making firm by ramming lift cylinder is installed at the top of unit, allows tamping unit in vertical (vertical) guide by the movement of this lift cylinder
It is slided on column, to complete the promotion and underthrust of tamping unit.
Tamping unit is slided vertical (vertical) in guide post, and the underthrust angle of final tamping pickaxe is vertical with plane on rail.
The violent swing of eccentric vibrating axis rotate driving opening and closing drive cylinder, then this swing is transferred to by tamping arm and is smash
Pick, to form the vibration of tamping pickaxe.
The expanding-contracting action of opening and closing driving mechanism is transferred to tamping pickaxe by tamping arm, to form the clamping of tamping pickaxe and open dynamic
Make.
2 are arranged above two rail and makes unit firm by ramming, while two sides rail is made firm by ramming；In switch zones when operation
4 can be driven to make being individually moved for unit firm by ramming by sliding of the guide sleeve on laterally steering column, to complete switch area
Domain tamping operation.
All tamping pickaxe structures used by the tamping unit of the utility model are completely the same, improve the exchange of components
Property, reduce the cost of tamping unit.
The utility model has following advantages and effect compared with prior art: only installing one on each tamping arm and smashes
Pick can meet the requirement in railway main track and switch area operation simultaneously simultaneously；2 are only equipped on each eccentric shaft to make firm by ramming
Arm, 2 tamping arms are mounted with tamping pickaxe respectively, alleviate the load of eccentric shaft, tamping pickaxe underthrust angle vertical is in flat on rail
Face reduces underthrust resistance；To extend the service life of eccentric shaft；The apparatus structure is reasonable, at low cost, and improves zero
The versatility of component, to reduce production cost.
Detailed description of the invention
Further explanation is said to the utility model with reference to the accompanying drawing.
Fig. 1 is the positive structure schematic of the utility model.
Fig. 2 is the left view for making unit firm by ramming of the utility model.
Fig. 3 is the utility model moving component action schematic diagram.
