Quan Xing.It is main to hammer ram weight and the requirement more and more higher of hoisting depth, the lifting of hammer ram with the continuous development of strong rammer technique
It is to be carried out by assembly pulley.The pulley body of the assembly pulley used on existing dynamic compaction machinery uses cast iron materials more, itself weight be present
Amount is big, and it is small to bear load, and the shortcomings of to wire rope fiction drive effect difference.
Utility model content
In view of this, main purpose of the present utility model is to provide a kind of dynamic compaction machinery assembly pulley.
To reach above-mentioned purpose, what the technical solution of the utility model was realized in：
A kind of dynamic compaction machinery assembly pulley, it is characterised in that：Including carrier base, pulley and baffle group, the carrier base bottom surface
It is connected to hydraulic jack；Carrier base upper end is horizontally disposed pulley spindle, and the pulley is set by one group of symmetrical clutch shaft bearing
In on pulley spindle, the pulley spindle both ends are also symmetrically provided with a pair of directive wheels by second bearing, are correspondingly provided with leading
Rail, the directive wheel move along the rail；The baffle group is by being connected to carrier base upper end and being symmetricly set in pulley axial direction both sides
A pair of baffle plates composition, be provided with several gear wheels between the baffle plate outer.
The baffle plate is inverse-T-shaped, and the gear wheel is arranged on "T"-shaped leg end.
The baffle plate is bolted on carrier base, and the gear wheel is connected between baffle plate by bolt, nut.

Compared with prior art, the beneficial effects of the utility model：
Pulley peripheral hardware gear wheel and baffle plate, can not only guide effect be played to the motion of steel wire rope, be also prevented from steel wire
Rope radially jumps, and improves its security；Pulley spindle does not support the effect of pulley only, is also associated with directive wheel, has guiding concurrently and makees
With；The connection of directive wheel and axle uses plastic bearing, can not only effectively reduce coefficient of friction, can also realize self-lubricating,
Simplify structure.
Brief description of the drawings
Fig. 1 is the utility model structural front view；
Fig. 2 is Fig. 1 A-A sectional views.
Wherein, 1- carrier bases, 2- pulleys, 3- baffle groups, 4- pulley spindles, 5- clutch shaft bearings, 6- second bearings, 7- are oriented to
Wheel, 8- gear wheels, 9- bearing caps, 10- lubricating cups, 11- guide rails.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.
The utility model embodiment provides a kind of dynamic compaction machinery assembly pulley, including carrier base 1, pulley 2 and baffle group 3, institute
State the bottom surface of carrier base 1 and be connected to hydraulic jack；The upper end of carrier base 1 is horizontally disposed pulley spindle 4, and the pulley 2 passes through one group pair
The clutch shaft bearing 5 of title is arranged on pulley spindle 4, and the both ends of pulley spindle 4 are also symmetrically provided with a pair by second bearing 6 leads
To wheel 7, guide rail 11 is correspondingly provided with, the directive wheel 7 moves along guide rail 11；；The baffle group 3 is by being connected to carrier base 1
Upper end and a pair of baffle plates composition for being symmetricly set in 2 axial both sides of pulley, are provided with several gear wheels between the baffle plate outer
8.Directive wheel 7 is slided up and down along guide rail 11, the terrain clearance of assembly pulley is adjusted by the effect of hydraulic jack, so as to
Change the terrain clearance of hammer body.
The baffle plate is inverse-T-shaped, and the gear wheel 8 is arranged on "T"-shaped leg end.Inverse-T-shaped baffle plate has three legs
Portion, the set location of leg are evenly arranged in the range of steel wire rope with pulley contact, and what is formed between gear wheel 8 and pulley 2 is narrow
