Abstract
The utility model provides a crab type travel mechanism of a road roller. The mechanism connects a front car frame and a rear car frame of the road roller together by using a articulated rack, a corresponding linking hole is respectively arranged on the front car frame and the articulated rack, a rectangular corner of the rear car frame is moveably connected with one side of the middle part of a swivel by an oil cylinder, relying to the stretching of the oil cylinder and the car frame locking hole and the locking up of the corresponding hole of the articulated rack, the road roller can approach and leave the border stone more easily during the road roller compacting in small track curve or at roadside, to avoid the miss rolling phenomenon because of the interference of the building barrier, thereby consequently improving the compacting quality in maximum limit.
Description
The utility model relates to a kind of steel roller.
At present, both at home and abroad the body frame structure for automotive pattern of road roller has two kinds of monolithic and radial types.The road roller of articulated frame (referring to full articulation) have mobility good, no matter be advantages such as straight-line travelling or negotiation of bends front and back wheel track can both overlap, therefore vibratory roller generally adopts this structural shape, the trend of also oriented this face development of quiet stone roller road roller.Yet no matter be the monolithic road roller, or articulated roller, current, when back wheel width equates, make that bend or road kerb compacting are wayward, or damage obstruction such as road kerb, the welt compaction capacity is very poor.
The purpose of this utility model provides a kind of crab row mechanism of steel roller, it can realize as required that the horizontal stroke of forward and backward steel wheel misplaces mutually, make road roller when carrying out bend or curb compacting, easier near and leave obstacles such as road kerb, building, avoid Lou pressing phenomenon, improve compaction quality to greatest extent because of interfering to produce.
The purpose of this utility model is achieved in that the front frame of road roller (1) is connected with body cradle (4) with jointed shaft (3) movingly with back vehicle frame (7); Have on the vehicle frame (1) with body cradle (4) on corresponding hole, hole (10) (2), side in the middle of the body cradle (4) has an oil cylinder connecting axle (5) to be connected movingly with an end of oil cylinder (6), and the other end of oil cylinder (6) is connected movingly with one jiao connecting axle (8) of vehicle frame (7).
The utility model is described in further detail below in conjunction with accompanying drawing:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the utility model oil cylinder contraction state schematic diagram;
Accompanying drawing 3 is the utility model oil cylinder elongation state schematic diagram.
With reference to Fig. 1,1 front frame, 2 vehicle frame pin-and-holes, 3 jointed shafts, 4 body cradles, 5 bearing pins, 6. oil cylinder, 7 back vehicle frames, 8 vehicle frame oil cylinder connecting axles, 9 front-wheels, 10 body cradle corresponding apertures, 11 trailing wheels.With reference to Fig. 2, as reference Fig. 2, when oil cylinder (6) shrinks, the locking pin-and-hole (2) of vehicle frame (1) aligns with body cradle corresponding aperture (10), can insert pin and fix, vehicle frame this moment (7) clockwise rotates, and the axis of wheel (9) and body cradle (4) form angle, the road roller of this moment promptly carries out turning motion; With reference to Fig. 3, the oil cylinder elongation, the front and back wheel of road roller is parastate, and this moment, the movement locus of road roller front and back wheel just can not overlap, and had promptly realized the function of crab row.
Because road roller installed said mechanism, can make road roller realize the transversion malposition of forward and backward steel wheel, when carrying out bend or curb compacting, easier near and avoid obstacle such as road kerb building, improve compaction quality to greatest extent.
Claims (3)
1, a kind of road roller with crab type travel mechanism is characterized in that: be connected movingly with back vehicle frame (7) with the front frame (1) of body cradle (4) with road roller with jointed shaft (3); Have on the vehicle frame (1) with body cradle (4) on corresponding hole, hole (10) (2), side in the middle of the body cradle (4) has a connecting axle (5) to be connected movingly with an end of oil cylinder (6), and the other end of oil cylinder (6) is connected movingly with one jiao connecting axle (8) of vehicle frame (7).
2, road roller with crab type travel mechanism according to claim 1 is characterized in that: body cradle and front frame (1), back vehicle frame can relatively rotate between (7).
3, road roller with crab type travel mechanism according to claim 1 is characterized in that: the hole (10) on oil cylinder (6) moves hole (2) and body cradle (4) to vehicle frame (1) can be with locking pin with vehicle frame (1) and body cradle (4) locking when overlapping.
