Abstract
The utility model relates to a crabbing device for a tandem vibratory roller which comprises a front frame, a steering frame, a crabbing frame and a rear frame which are connected together, wherein, the front frame is connected with the rear frame via the steering frame and the crabbing frame, a centered pin hole is designed on the lower connecting plate of the steering frame, three centered pin holes are designed on the lower connecting plate of the crabbing frame, and by means of pins, and the connecting plates of the steering frame and the crabbing frame are mated according to different pin holes in order to realize normal running or the bidirectional crabbing of two steel wheels. Compared with the prior tandem vibratory roller controlled by crabbing hydraulic cylinders, a group of hydraulic cylinders and related electric control elements are left out, the crabbing device utilizes the different matchings of the pin holes on the connecting plates of the steering frame and the crabbing frame to realize crabbing, so the structure is simple, and cost is reduced.
Description
Technical field
The utility model relates to the road roller tool, particularly the crab of vibratory roller row mechanism.
Background technology
Double-steel wheeled vibratory roller is present common a kind of road roller tool, and it is when operate as normal, and no matter require is in straight-line travelling or negotiation of bends, and its forward and backward steel wheel track can both overlap, and this road pavement compacting is favourable.Yet, when special operation condition,, make that bend or curb compacting are wayward, or leak pressure, or damage road kerb exactly because forward and backward steel wheel track overlaps.In order to overcome double-steel wheeled vibratory roller uppity shortcoming when carrying out bend or curb compacting, used the double-steel wheeled vibratory roller that can carry out the work of crab row.Majority can carry out the double-steel wheeled vibratory roller of crab row work all by the control of crab row hydraulic jack at present, this double-steel wheeled vibratory roller must have one group of crab row hydraulic jack and relevant appliance controling element, so complex structure is made trouble, the production cost height.
Summary of the invention
The purpose of this utility model provides a kind of crab row mechanism of double-steel wheeled vibratory roller, this crab goes mechanism without crab row hydraulic jack, can realize the transversion malposition of forward and backward steel wheel as required, make road roller when carrying out bend or curb compacting, easier near and leave road kerb, avoid pressure with Louing and interfere phenomenon, thereby raising compaction quality, and simple in structure, assemble easyly, can reduce manufacturing cost.
The purpose of this utility model realizes by following scheme: a kind of crab row mechanism of double-steel wheeled vibratory roller, be interconnected to constitute by front frame, bogie, crab row frame and back vehicle frame, front frame is connected the back vehicle frame by bogie with crab row frame, centering is designed a pin shaft hole on the gusset piece of the lower end of bogie, symmetric design several pin axis hole on the lower end gusset piece of crab row frame can match two gusset pieces of bogie and crab row frame by bearing pin and to be connected by different pin shaft holes.
In technique scheme, but the pin shaft hole of symmetric arrangement can be 3 or 3 above odd number pin shaft holes on the gusset piece of crab row frame lower end.Bearing pin can form different crab row amounts when different pin shaft holes position.
The capable mechanism of this double-steel wheeled vibratory roller crab compares with existing double-steel wheeled vibratory roller crab row mechanism by the control of crab row hydraulic jack, omit one group of crab row hydraulic jack and relevant appliance controling element, match with the pin shaft hole on bogie and the crab row frame gusset piece different and to carry out the crab every trade and sail, so simple in structure, reduced cost.
The utility model has the advantages that: one, complete machine low cost of manufacture; Two, simple in structure, the assembling easy, easy to maintenance, not fragile; Three, can adjust crab row amount according to different operating mode needs, improve the compaction quality on road surface.
Description of drawings
Fig. 1 is the structural representation (cruising state) of the utility model system.
Fig. 2 is the crab row structural representation when the crab every trade is sailed left.
Fig. 3 is the crab row structural representation when the crab every trade is sailed to the right.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing 1 is the crab row mechanism structure schematic diagram of this double-steel wheeled vibratory roller, comprises front frame (1), preceding steel wheel (2), crab row frame (3), bearing pin (4), bogie (5), back vehicle frame (6), back steel wheel (7).
Accompanying drawing 1 is this double-steel wheeled vibratory roller cruising (coincidence of a front and back wheel track) state.The front frame of double-steel wheeled vibratory roller (1) is connected back vehicle frame (6) by bogie (5) with crab row frame (3), a pin shaft hole of centering design on the lower end gusset piece of bogie (5) by three pin shaft holes of bearing pin (4) and centering design arrangement on the lower end gusset piece of the capable frame of crab in the intermediate pin axis hole match, can realize cruising.
Accompanying drawing 2 for this double-steel wheeled vibratory roller left the crab every trade sail (the relative trailing wheel of front-wheel staggers) left, promptly by road left side transport condition.Pull up bearing pin (4), spin, when forwarding position shown in Figure 3 to, bearing pin (4) is inserted in the respective pins axis hole, oppositely spin, realize that the crab every trade is sailed left to making front frame (1) and afterwards vehicle frame (6) is parallel to crab row frame (3) and bogie (5) are relatively rotated.
Accompanying drawing 3 for this double-steel wheeled vibratory roller to the right the crab every trade sail (the relative trailing wheel of front-wheel staggers) to the right, promptly by road the right transport condition.Pull up bearing pin (4), spin, when forwarding position shown in Figure 4 to, bearing pin (4) is inserted in the respective pins axis hole, oppositely spin, realize that the crab every trade is sailed to the right to making front frame (1) and afterwards vehicle frame (6) is parallel to crab row frame (3) and bogie (5) are relatively rotated.
Claims (2)
1, a kind of crab of double-steel wheeled vibratory roller row mechanism, it is characterized in that this mechanism is interconnected to constitute by front frame, bogie, crab row frame and back vehicle frame, front frame is connected the back vehicle frame by bogie with crab row frame, centering is designed a pin shaft hole on the gusset piece of the lower end of bogie, symmetric design several pin axis hole on the lower end gusset piece of crab row frame can match two gusset pieces of bogie and crab row frame by bearing pin and to be connected by different pin shaft holes.
2,, but it is characterized in that the pin shaft hole of symmetric arrangement on the gusset piece of crab row frame lower end can be 3 or 3 above odd number pin shaft holes according to the capable mechanism of the crab of the double-steel wheeled vibratory roller described in the claim 1.
