Description

BACKGROUND OF THE INVENTION The present invention relates to a locking device of a hand-guided vibratory roller with a steering bogie during its transport, in particular during lifting.

At present, in the case of manually guided vibratory rollers with steering bogie, flexible elements (silentblocks) are used to connect the steering bogie to the machine frame and the drive unit is also resiliently mounted on the vibration part of the machine. In order to minimize the transmission of vibration to the handle of the steering bogie, the steering bogie is connected to the spring-loaded part of the cylinder (on which the drive unit is mounted). This arrangement of the machine creates a transport problem where the roller needs to be moved by means of a lifting device. The vibratory roller is thus divided into three mutually resilient assemblies which form a vibratory portion with treads, sidewalls, a vibration exciter and a transmission; suspension part with frame, engine, gearbox, pump and tanks and drivers chassis with frame, handle and steering wheel. When transporting such a machine, it is necessary to use five ropes when lifting, which is particularly disadvantageous in terms of matching the correct rope lengths. Another method of transport can be used, but the driver's chassis would have to be disconnected, which causes considerable time losses when loading the machine and this method is relatively laborious.

These drawbacks are overcome by the locking device according to the invention, characterized in that the control arms, the suspension arms and the side walls of the vibration part are provided at opposite heights with mutually opposite openings into which

210 595 a locking rod is inserted. The lower ends of the joints of the spring-loaded part are simultaneously provided with abutments which are fixed at the level of the connecting tube. The transverse abutments extend beyond the resilient elements connecting the steering bogie with the spring-loaded front and inwardly supporting the flanges of the connecting tube when raised.

The advantage of the device according to the invention lies in simplicity The arrangement does not create any special demands on the operator when moving the hand-guided vibratory roller and the undercarriage.

One example of an embodiment of the locking method according to the invention is shown schematically in the accompanying drawings.

Fig. 1 is a side view not of a manually guided vibratory roller e by not marking the rope attachment; Fig. 2 is a front view of a manually guided roller; Fig. 3 is a detail view of the steering suspension mount; Fig. 5 is a top view of the connection of the contact arm of the spring-loaded part and the connecting tube by means of resilient elements.

Hand-guided vibrating roller (Fig. 1, 2) It consists of three elastically connected units. The vibration portion 4 of the cylinder 10 is connected by a spring element 11 to the spring element 11 by means of a coupling tube 8 connected to the control chassis 7. The connection is effected by means of spring elements 16, 16 '(FIG. 3). is fastened by one surface to the flanges 19, 19 'of the connecting pipe 8 e by the other surface to the contact arms 18. 18' of the suspension part 11. The contact belts 17, 17 'of the steering bogie 7 are fixed to the center of the connecting pipe 8. 3 'the vibration bar 4 is provided with an anchorage point 2, 2 ' for the cable 1, 1 ' in the front bar and a loop 6 for the rope 5 is formed on the steering chassis 7. The spring bar 11 is not cushioned. The abutments 9, 9 '(Figs. 4, 5) are fixedly fixed and, at the same time, a pair of holes 13, 13' are formed in the sides 3, g 'of the vibration bar 4. Further, the openings 14, 14 'are formed in the contact arms

18. 18 'springed Part 11 and openings 12, 12' in contact arms 17 '22' of the steering bogie 7 (Fig. 4).

When the cylinder 10e is moved with the beverages, it does not have the attachment points 2, 2 'and the rope 5 on the eye.

6. Lift the chassis 7e ee so that the openings lg, 12 ', 13, 13', 14, 14 'are covered and the locking rod is pushed through the space thus created. Upon further lifting of the entire cylinder 10, the resilient elements 16, 16 '(non-resilient is allowed) and the flanges lg, lg' of the connecting tube 8 of the steering gear 7 abut against the supports 9, g '. Tim The entire cylinder 10 is fixed for lifting by three ropes.

The device according to the invention can be used in machines and devices by resiliently interconnecting the individual parts divided into three units, especially in the hand-guided vibratory rollers and the steering bogie.
