Protective device for a chassis with articulated frame

 

The invention relates to the field of municipal and road-building machines and, in particular, to machines having a chassis comprising two articulated semiframes. Protective device made of curved limiter located in the area above the rotary hinge semiframes, defined by the radius from the center of rotation of semiframes fixed with their ends by uprights at the front end and supported by support rollers on vertical racks on the back end. The technical result is protection from injury in case of finding it in the zone folding semiframes when turning the machine. 5 Il.

The invention relates to the field of municipal and road-building machines and, in particular, to machines having a chassis comprising two articulated semiframes, and specifically to devices designed to protect against injury, possibly in the zone folding semiframes when turning the machine.

Known road-building machine, chassis, which consists of two articulated semiframes on which is mounted cargo handling equipment [1]. The disadvantage of it is that when turning m is given the danger zone, where can a man be. Such a situation can be created and maintenance of the machine.

Known to use the text alerts to work with chassis with articulated frame, made in the form of inscriptions, engraved on one of the semiframes, warning about the danger of finding a person between frames [2] . The disadvantage of this solution is that this warning may not always be done inadvertently, and for other unforeseen reasons.

Therefore, the problem to be solved in the proposal the applicant is creating a reliable protective device to prevent a person staying in the danger zone.

It is also known chassis multifunction machine for mounting interchangeable working equipment and municipal purposes, including articulated frame, consisting of two front and rear semiframes [3].

The downside of it is the lack of devices that prevent exposure in the hazardous zone folding of semiframes.

The proposal of the applicant are considered in relation to the specified chassis.

Thus the solution of the problem posed in this proposal lies in the fact that the protective ostego limiter, located in the area above the rotary hinge semiframes, defined by the radius from the center of rotation of semiframes fixed with their ends by uprights at the front end and supported by support rollers on vertical racks on the back end.

In Fig. 1 shows a General view of the protective device from the side; Fig.2 - the same in plan; Fig.3 - view page a in Fig.1; Fig.4 - node In Fig.2; Fig.5 is a section along B-B in Fig.4.

Arcuate stopper 1 has a shape in plan, defined by the radius D, and secured to the uprights 2 and 3 with their ends 4 and 5. Columns 2 and 3 are installed on the front end 6 of the chassis 7, and the rear section 8 installed rack 9 on the upper parts of which are mounted rollers 10 that its bottom surface rests limiter 1. The limiter is made of two strips 11, interconnected by spacers 12.

Works as a protective device in the following way. When turning semiframes 6 and 8 their corners 13 and 14 closer together, reducing the distance between them. The limiter 1, turning together with the front end 6, is rolled over the support rollers 10 rear semi-frames 8 and constantly overlaps the danger zone D, preventing the possibility of finding in her the human is, participating in the process of operation of the machine with articulated frame.
