Description
Technical field
A kind of tension structure is the utility model is related to, is used for more particularly, to a kind of to the driving chain on rubber-tyred roller
The mechanism being tensioned, belong to field of road engineering machinery field.
Background technology
At present, rubber-tyred roller is pressed because it has good flexible compaction capacity and will not destroyed in compacting process
Real aggregate, therefore become compacting class mechanical engineering equipment essential in asphalt pavement construction, it is usually used in asphalt road
Face pressure reality and the compacting of stabilized soil road base；
The common drive form of domestic rubber-tyred roller is mainly rear wheel drive, and drive axle drives trailing wheel by driving chain
Driven sprocket is driven, and Chain conveyer manufacture and installation accuracy require relatively low, and bearing capacity is larger, there is certain buffering and damping
Performance, transmission efficiency is higher, therefore is widely used at home；But after chain drive for a period of time, chain can occur
Abrasion elongation, although relatively slower, extended with the abrasion of chain, cause slack list sag excessive, caused and engage bad and chain
Bar is vibrated and the generation of tooth is jumped in transmission, therefore just needs to be tensioned driving chain；
Nowadays the rubber-tyred roller chain tensioning mechanism of domestic each producer mainly by the way of centre-to-centre spacing is adjusted, raises drive
Movable sprocket, so that chain tension, its design structure is substantially as shown in Figure 2：By the closely-pitched screw rod at centre of sprocket line both ends
101st, bridge seat 102 and hold-down bolt 103 is driven to form；
Above-mentioned adjustment mode realizes that the process of the tensioning of chain is comparatively laborious, drives between bridge seat 102 and closely-pitched screw rod 101
It is smaller to be threadedly coupled gap, need to first adjust one end closely-pitched screw rod 101, and the distance of very little can only be adjusted, then adjusts other one
End, otherwise occurs thread biting locking phenomenon, it is therefore desirable to which the continuous small distance of repetition adjusts left and right closely-pitched screw rod 101 respectively makes drive
The dynamic lifting of bridge seat 102；After both ends closely-pitched screw rod 101 is adjusted to correct position, four hold-down bolts 103 are tightened；Due to
Rubber-tyred roller is compact-sized, and vehicle frame is totally enclosed type unitized frame, and the instrument of closely-pitched screw rod 101 in inner side is relatively inaccessible to grasp
Make position, adjustment could be realized after water tank and other associate members need to be dismantled；The bottom locating surface of closely-pitched screw rod 101 and frame contact,
Due to the frictional force of drive axle own wt increase contact surface, cause to adjust the larger moment of torsion of closely-pitched screw rod needs, adjusted in building site
It is whole to employ larger air pressure gun and be adjusted, and once tensioning need to adjust four closely-pitched screw rods 101；Therefore adjustment chain quantities
Greatly, adjustment is difficult.
The content of the invention
A kind of the purpose of this utility model is to overcome above-mentioned deficiency, there is provided wheel tire pressure road simple in construction, easy to maintenance
Machine driving chain tension structure.
What the purpose of this utility model was realized in：
A kind of rubber-tyred roller driving chain tension structure, the structure include the chain being installed on driving bridge seat
Wheel；
A screw rod is horizontally arranged with below the driving bridge seat, the left and right ends of the screw rod are revolved respectively is equipped with a guiding left side
Revolve threaded block and be oriented to right-handed thread block,
Left connecting rod component includes two connecting rods, is hinged and connected at the top of connecting rod above with driving bridge seat in be hinged
Point one, underlying connecting rod bottom and frame are articulated with pin joint three, the bottom of connecting rod above with it is underlying
The top of connecting rod is articulated with by pin joint two and is oriented on left hand thread block；
Right connecting rod component includes two connecting rods, be hinged and connected at the top of connecting rod above with driving bridge seat in
First pin joint, underlying connecting rod bottom are articulated with the 3rd pin joint, the bottom of connecting rod above with frame
It is articulated with and is oriented on right-handed thread block by the second pin joint two with the top of underlying connecting rod.
A kind of rubber-tyred roller driving chain tension structure of the utility model, on the screw rod rotation be equipped with a locking nut；
For carrying out locking to being oriented to left hand thread block or being oriented to right-handed thread block.
A kind of adjusting method of rubber-tyred roller driving chain tension structure of the utility model, during regulation：Unclamp locking screw
Mother, drive screw rotation, its thread belt action-oriented left hand thread block and guiding right-handed thread block are inwardly tightened up after screw rod rotation, left
Locking nut is tightened behind link assembly and upward lifting driving bridge seat to the target location of right connecting rod component, so as to complete to sprocket wheel
The tensioning of upper chain.
Compared with prior art, the beneficial effects of the utility model are：
The utility model passes through screw rod and guiding left hand thread block, the rotary flat for being oriented to right-handed thread block composition feed screw nut
Converting mechanism is transferred, and left hand thread block is directed to by left connecting rod component and right connecting rod component, is oriented to the flat of right-handed thread block
Shifting movement is converted to oscilaltion campaign, and total is simple, reliable, and either regulation or maintenance is all extremely convenient.
