DE423044C - Safety device for the tipping process in the case of box vans unloading on one side - Google Patents

Description

In the patent specification 413551 a device for the execution of tipping processes in unloading box vans is described, in which the upper link of the 'articulated lever pairs g, g connecting the car body with the undercarriage in a known manner in the crank point as an angle lever with a bolt inserted at a certain distance is 0 0. like provided or formed through which the specially designed tipping hook tipping of the carriage h is such that both joint members g ·, g 'and the rocker arm h directly on the upper and lower parts are hinged distance determining and for the Tilting back the roller r attached to the lower part comes into effect by means of the rocker arm h , and that the tilt hook h is closed like a fork at k and is designed so that at k it strikes the car body against tipping over against the lateral support i. To secure these tilting processes, the subject matter of the present invention relates to the attachment of special devices that are intended to secure the respective position of the car body.

In the drawing, a vertical section through the car in the tilted position and in Fig. 2 through the car in the rest or driving position is shown in Fig. According to the invention, the lever /; which can be rotated around the bolt u and which can be set up to accommodate the tilting boom Z at the same time, is provided at its lower end with a nose s which, in the rest position according to Fig. 2, is at the angle t used on the longitudinal boom summarizes and if the holding members are unlocked g, g 'the car body against unintentional tipping, z. B. while driving on a very bad track, secures. The nose s is also attached in such a way that, in the event of any breakage of the holding members g, g ', it secures the car body in the end tilting position by stopping against the rollers r, as shown in FIG. A special movement that is necessary outside of the tilting process is neither required when tilting nor when tilting back, so that neither loss of time nor disturbances can occur during the tilting process. When tilting, the nose s is released from the angle t by the required turning movement of the lever h; when tilting back, the nose lies down. again securing under the angle without any special auxiliary device. Furthermore, a bracket u, closed at the top, is provided on the tilting boom Z or directly on the tilting lever h and is rotatably mounted in the bolt w. When tilting back into the rest position, by lifting the lever h, the holding members g, g 'are brought out of the extended position by stopping the lever h on the bolt 0, i. H. unlocked; this is the same process as when tilting. When the lever h is raised, the bracket u falls into the hook v attached to the box. Pulling the inserted tree Z causes the tilting back movement. From a certain tilt angle on, the pressure of the lever h on the rollers?; a, whereby the connection of the lever u with the hook ν is released again. With this arrangement, the chain otherwise connecting the tilting boom or tilting hook and the retaining links can be omitted. On the tilting side of the box, a support χ is rotatably or pivotably attached to the bolt y, which in the rest position of the car with the nose x 'grips under the bar 2 and secures the box against tipping over to the operator side. This is an increase in the security already provided by the support chair e and the articulated rods g, g '. In the final tilting position, the fio support χ lies with its nose x 'on the running rail and thus supports the box and its underframe against tipping over towards the unloading side. If the ground is still stuck in the bent half of the box after tilting if the ground is unfavorable, it can happen that the car body hits back with force and tips over from the lower part. Against such occurrences, the nose x 'protects, which in this case automatically grips under the strip ζ and holds the car body in place. The combination of the measures just described creates an extensive safeguard for operation with such box vans. Sponsorship τ claims: 1. Safety device for the tipping operations in unloading box vans according to patent 413551, characterized in that a nose (s) is attached to the rocker arm (Ji) at a certain distance so that it is in the rest or driving position under the angle (i) or the like and in the end tilt position under single or multiple attached rollers (r) or the like. 2. Safety device according to claim i, characterized in that on the lever (Ji) or on the tilting boom (Z) a bracket (u) is attached by a bolt (w) so that it is in the box by lifting the tree (Z) attached hook (v) can be inserted and so the joint (g, g ') is brought from the dead position by pressing the lever (Ji) on the bolt (0), whereby the bracket (u) automatically after a certain backward movement of the box is disengaged in that the lever (Ji) comes to rest on the rollers (r) for further movement up to the rest position. - 3. Safety device according to An-Spruch ι and 2, characterized in that 'that on the tilting side of the car a support (x) is attached to the bolt (y) so that it is in the rest position under a bar attached to the chassis (s) 13.0 grabs and in the end tilt position is supported with the nose (x ¹ ) on the rail. 1 sheet of drawings.
