Description

Articulated trolley for the transport of hangers of hams in dryers.

The present invention relates to a car suspended from those used in dryers for the transport of hams on hangers, which presents the novelty of being constituted, to unlike those known, for an articulated body around a vertical axis and by three guided driving wheels instead of the two presented by the non-articulated, all of which facilitates their offset in curves. In addition the car is equipped with four wheels that move on guide rails and the two wheels sides are replaceable on the way, without having to lower the carriage that transports the hanger on which the hams

It falls within the field of industrial facilities of dryers, specifically of hams, providing a new configuration that involves significant Advantages to the current state of the art.

Carts are known for transporting hams in dryers, of different designs and of operation conventional, consisting of a metal body that is usually aluminum, usually T-shaped on whose top plate they incorporate a transverse axis and two wheels that run on rails hanging guides provided with lower sub-guides conformed these by the own profile of the rails in his part lower, sliding between the sub-guides one or two driving wheels that revolve around vertical axes conventional, intended to fix the trajectory, especially in the curves, preventing fluctuations and consequent friction. At lower end of the car body is a hook articulated whose mission is to hold the hanger from which hang the hams, about 46 whose total weight ranges between 700 and 1000 kilograms

These cars belonging to the state of the technique have several drawbacks, the most relevant being that derives from the extremely complex and expensive operation that it is necessary when you have to proceed to the replacement of a rulina driving, which when exposed to strong tensions, especially in curves, it loses its stability or it wears out or breaks causing the interruption of transport. In that case, which usually be frequent in the often too tight entrance curves to cameras, we must proceed to lower the car to replace the Rulina driving in workshop. But to lower the car is it is necessary to proceed to the descent of all the cars that precede it until you reach the beginning of the guide beam or all the cars that follow you until you reach the end of the guide beam, that is to say only two points where cars enter or leave the guide, since otherwise it is impossible to lower it. This operation consumes a exaggeratedly long time, stops the march of the dryer, is especially expensive and if frequent can cause damage Irreparable in the industry. To this significant inconvenience we must join others of lesser consideration, such as evil behavior presented by the car with only two wheels in the curves, its lower resistance than the four wheels, as well as the also lower resistance of the aluminum car compared to steel stainless.

These inconveniences were partly resolved by document P 200.501.268 which consists of a car for the transport of ham hangers in dryers equipped with a body Elongated stainless steel T-shaped, whose plate upper supports two perpendicular axes around which four wheels pivot, two on each side of the plate, very close each other and allowing the ends of the bumper plate. Immediately below, in the upper part of the vertical body of the car is two crossarms horizontal that support two vertical axes on which pivot the driving wheels. These axes are imprisoned by means of a screw, so that they can be easily released from its housing by loosening the through screw and leaving Drop the shaft by its own weight.

The described solution has the drawback that in the curves the behavior of the car is poor at face the problem that the four wheels, being solidarity and devoid of articulation between them, they cannot adapt properly in the caves, but they skid and brake normal displacement on the rails along which they advance. This It produces wear on the wheels and on the wheels. If wear is very pronounced to the point of having to change the wheels or the rulinas, we must proceed to get off the chain all the cars before reaching the one to be replaced, which produces Disorders of considerable amount.

This considerable inconvenience is solved with the present invention, which consists of a car for the suspended transport of hams on guide rails in dryers, constituted from two elongated stainless steel plates, although they can also be made of aluminum, articulated by an axis central in whose heads are four wheels, two for each plate, arranged horizontally to these, each pair with its perpendicular axis, running along the guide rails of the beam that with its respective curves it forms the route through the dryer. On each side of the plates, a short distance from the wheels fit in two housings two wheels that rotate in around a removable vertical axis through screw, being able to the rulinas be replaceable on the road with just de-tightening the screws that imprison the shaft, remove the released shaft and replace the rulina. The mission of the rulinas is to stay the course and avoid carriage balancing. The axis of articulation of plates consists of an upper and lower part. The upper holds in its center a third vertical roller like than the other two and at the same height, further minimizing the car balancing effect and better maintaining the trajectory of East. The axis of this third roller consists of a through screw with nut at the lower end. The bottom of the shaft of articulation of the plates is constituted by a bolt that holds the hook of the hanger at its lower end, which articulates around a horizontal axis and presents a drill bottom for fixing the hanger.

This invention seeks to improve the operability and functionality of the suspended career of driving hams in the dryer, minimizing the difficulty of take the curves of the beam with its rails that guide the cars on their way in the dryer. It's also about reducing costs due to wear of wheels and routines and confer  Greater security on the tour.

In this sector of the technique, those prevail effective developments and specifically dedicated to the function, which result in a robust and safe system with low cost and results technically appreciable. The fact is particularly interesting. that a car can be used to transport hams in dryers like the one proposed in the present invention by Advantages that have previously been highlighted. For the best understanding of what is described herein is accompany some drawings in which by way of non-limiting example a case study of the carriage is shown for the transport of hams in articulated dryers for your best transportation on the way:
