The adjusting device comprises a connecting frame used for installing a drive bridge, two groups of support seat, screw rods, and two pull rods, wherein the two ends of the connecting frame are installed on the support seats by virtue of a knuckle bearing respectively, the screw rods are connected with the connecting frame by virtue of thread pairs, the lower ends of the screw rods are contacted with the upper ends of the support seats, the knuckle bearings are in clearance fit to the support seats, each screw rod above the connecting frame is provided with a nut used for location, the pull rods are connected between the connecting frame and the support seats, and each pull rod arranged above the connecting frame is provided with a gland nut used for controlling the connecting frame to be located on the support seats; the nut and the gland nut are unscrewed, the screw rods are rotated to drive the connecting frame to move up and down under the guiding action of the support seats, and the drive bridge on the connecting frame is driven to move up and down to adjust the tightness of the chain. According to the adjusting device, the adjusting operation is convenient, the time and the labor are saved, the assembling requirements of the support seats and the part manufacturing accuracy are lowered, and the production cost is reduced.
Description
Technical field
The utility model belongs to pavement construction machinery field, relates in particular to a kind of rubber-tyred roller chain adjusting device.
Background technology
Rubber-tyred roller be a kind of by special pneumatic tire to laminated material the compacting machinary with Static compaction effect, because of its good compaction capacity, the range of application of product is increasingly extensive.For using roller chain power to be passed to the form of structure rubber-tyred roller of driving wheel, after chain, sprocket wheel appearance wearing and tearing, need often to adjust the elasticity of chain, to reduce impact, ensure stable drive.During due to compacting operation road roller be front and back come and go travel, driving wheel need change rotation direction to be realized, therefore driving wheel positive and reverse steering is alternately frequent, the chain tension form of tension wheel structure is difficult to adopt, and conventionally adopts the intermediate distance that regulates drive axle installing rack to change drive axle and driving wheel to adjust the rate of tension of chain.
As shown in Figure 3, existing drive axle installing rack comprises four column a, base b and link c, and column a lower end is sleeved in base b, and link c is directly connected with column a by screw thread pair, for ensureing the stable of drive axle, the gap between column a and base b, column a and link c is all less.Mainly there is following shortcoming in it: one, because screw thread pair joint gap between link and column is less, four columns rotate respectively while adjusting, can only every less angle of each progressively rotation, guarantee link and drive axle are parallel to be moved up and down, once the anglec of rotation of certain part column is slightly large, just there will be screw thread pair to kill phenomenon, adjust troublesome poeration, waste time and energy, on workshop, condition is simple and crude, limited by locus, adjusts difficulty larger, consuming time many, cost is high.Two, because the gap between column and base is less, make four columns can rotate respectively adjusting, must ensure that four columns are parallel to each other when floor installation, therefore the plane of rack degree of mounting seat requires tighter, need higher making precision, and frame is all welding structural element, volume large (generally all 2 meters × more than 4 meters), weight heavier (generally all at 5 to 10 tons), welding deformation is large, machining difficulty, controls complex process to it, and cost of manufacture is high.
Utility model content
The purpose of this utility model is to provide a kind of parallelism that can ensure between column, can effectively solve the rubber-tyred roller chain adjusting device that chain regulates the large problem of difficulty, increases work efficiency, reduces use cost.
This rubber-tyred roller chain adjusting device that the utility model provides, comprise the link that drive axle is installed, also comprise two groups of supporting seats, screw rod and and two pull bars, the two ends of described link are respectively arranged on supporting seat by an oscillating bearing, described screw rod is connected with link by screw thread pair, the lower end of this screw rod contacts with the upper end of supporting seat, between described oscillating bearing and supporting seat, adopt matched in clearance, on the each screw rod above described link, be provided with location nut, described pull bar is connected between link and supporting seat, on the each pull bar above described link, be provided with the clamp nut of locating for control connection frame on supporting seat, unscrew nut and clamp nut, rotary screw drives link to move up and down under the guide effect of supporting seat, drive moves up and down adjusting chain elasticity with the drive axle on link.
Compared with prior art, the utlity model has following advantage:
1, because the utility model is by oscillating bearing, link to be connected with supporting seat, make the skew that allows to produce certain angle between link and supporting seat, and the contact surface of screw rod and supporting seat is also relatively little, moment when rotary screw is little, when adjusting chain, as long as unscrew the nut on each screw rod, then rotary screw, just can realize trippingly the tensioning of chain or loosen, and adjusts easy to operate, save time, laborsaving.
2, because screw rod of the present utility model and supporting seat separate, between link and supporting seat, be connected by oscillating bearing, when adjustment, between each part, all allowed relative displacement, reduced matching requirements and the component accuracy of manufacture of supporting seat, reduced cost of production.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is the utility model road roller chain drive assembling drawing.
Fig. 3 is the structural representation of prior art.
Detailed description of the invention
Can find out from Fig. 1 and Fig. 2, this rubber-tyred roller chain of the utility model adjusting device, comprise the link 1 that drive axle is installed, two groups of supporting seats 2, two oscillating bearings 3, the nut 4 of two location use, two screw rods 5 and two pull bars 6, the two ends of link 1 are respectively arranged on supporting seat 2 by an oscillating bearing 3, screw rod 5 is connected with link 1 by screw thread pair, the lower end of this screw rod 5 contacts with the upper end of supporting seat 2, between oscillating bearing 3 and supporting seat 2, adopt matched in clearance, nut 4 is arranged on each screw rod 5 of link 1 top, pull bar 6 is connected between link 1 and supporting seat 2, on the each pull bar 6 above link 1, be provided with clamp nut 61, clamp nut 61 moves down, controlling pull bar 6 is pressed on link 1 on supporting seat 2 by screw rod 5.
As can be seen from Figure 2, in road roller chain transmission system, drive axle A is arranged on link 1 of the present utility model, the bearing fixed seat of driving wheel C and supporting seat of the present utility model 2 are fixedly connected on respectively in frame, the moving force and motion of drive axle A is passed to driving wheel C by chain B, impact for reducing, ensure stable drive, the application life of raising equipment, need often to adjust the elasticity of chain, when adjustment, only need unscrew the nut 4 on clamp nut and screw rod 5 on each pull bar 6, rotary screw 5 drives link 1 to move up and down under the guide effect of supporting seat 2, drive moves up and down with the drive axle A on link 1, can realize the adjusting of chain elasticity.
