Description

OUTRIGGER STRUCTURE FOR MACHINES
The invention relates to an outrigger structure for machines, particularly for passenger cage elevators to be chocked during its operation, the structure consisting of a shore element having a base member connected pivotally to an end of said structure, and a working cylinder an end part of which is fitted pivotally to the base member, and an end part of the piston of said cylinder is pivotally connected to the shore element near an end location thereof, and a ground plate hinged to the end of the shore element. Such outrigger structures are typically fixed to the carriage of the machine to be chocked, at four corners thereof. The aim of chocking up is that the machine be safely supported on the ground without tilting during operation, e.g. with a person working in the cage craned up possibly making electric or other tasks to be carried out aheight. Steadiness necessary to the working process is assured by a combination of above hydraulically movable structures having adequate strength fixed to the carriage of the machine and the weight of the machine itself. In addition to chocking there is a further requirement to align the carriage of the machine with the horizontal plane. Passenger cage elevator is operated by its own power source with outrigger structures in raised position. Known and applied outrigger structure made by the firm Teupen Hungaria is not able to achieve these aims. Namely, the passenger cage elevator machine of Teupen firm requires a lateral- radius of 7,2 m, involving an outrigger surface or outrigger length of more than 1980 mm, which would be higher than the prescribed height of the machine. In the case of building in said lengthened structure it is impossible to achieve an outrigger level difference of 450 mm, or the prescribed maximum 780 mm width of the machine would be greater. Therefore, an object of the invention is to construct an outrigger structure providing an adequate an steady chocking effect at the four corners of the machine and allowing the machine, e.g. a passenger cage elevator, to operate safely even in case of extreme ground conditions.
This object is achieved by providing an outrigger structure for machines, particularly for passenger cage elevators to be chocked during its operation, the structure consisting of a shore element having a base member connected pivotally to an end of said structure, and a working cylinder an end part of which is fitted pivotally to the base member, and an end part of the piston of said cylinder is pivotally connected to the shore element near an end location thereof, and a ground plate arranged hingedly to the end of the shore element. Outrigger structures are fixed at each four corners of the machine, as it is familiar in the state of the art.
An inventive idea of the invention is that the outrigger structure will have a better alignment or adjustment ability, when a shore element is connected to the base member by means of link mechanism, and its end is movable along a roller cam path fixed to the base member. Therefore the essence if the invention is that a casing of a link mechanism is connected to the end of the shore element, and a die block arranged slidably in the casing is fixed pivotally to the base member, and a roller being able to revolve along a roller cam path fixed to the base member is fitted with bearing at the end part of the casing. Outrigger structures according to the invention are placed at the four corners of the machine providing a perfect chocking up effect even in case of extreme ground conditions.
The invention will be discussed in details according to exemplary embodiments and drawing attached. In the drawing Fig. 1. shows outrigger structures according to the invention applied to a passenger cage elevator machine, with the four outrigger structures in raised position; Fig. 2. shows the passenger cage elevator machine in closed position, but outrigger structures according to the invention are projected; Fig. 3. is a top plan view of the passenger cage elevator depicted in Fig. 2;
Fig. 4. is a passenger cage elevator showed in Fig. I1 2., and 3. in closed position and chocked up in case of extreme ground conditions; Fig. 5. is a front elevation view of the machine depicted in Fig. 4.;
Fig. 6. is a basic structure of the outrigger structure according to the prior art;
Fig. 7. is an embodiment of an outrigger structure according to the invention in base position; Fig. 8. is an outrigger structure according to the invention commencing the chocking procedure; and
Fig. 9. is an outrigger structure according to the invention in its lateral chocking up position.
Passenger cage elevator machine 10 showed in Fig. 1. has outrigger structures according to the invention fixed to its 11 carriage, depicted in base position. Fig. 2. shows the same machine 10 in a chocked up position with outrigger structures fixed to its 11 carriage in chocking position, projecting outwardly. Fig. 3. shows a top plan view of four outrigger structures according to the invention in chocked up position. Fig. 4. shows the outrigger structures fixed to the carriage 11 of the machine yet closed but chocked up in case of extreme ground conditions. Fig. 5. is a front elevation view of the same machine.
Theoretical design of an outrigger structure known in the art is depicted in Fig. 6., this structure has a shore element 1 having a triangle shaped base member 2 connected pivotally to an end thereof. To the other end part of the base member 2 a working cylinder 3 is connected by a pivotal point 5 and the piston 6 rod of said cylinder 3 is pivotally 7 fitted to the shore element 1 near a lower end location thereof. The shore element 1 is provided with a ground plate 8 arranged hingedly on the lower end thereof, providing the actual support.
Fig. 7. shows an embodiment of an outrigger structure according to the invention in its raised base position. According to the invention, a casing 9 of a link mechanism is connected to the end of the shore element 1 opposite the end part provided with the ground plate 8. A die block 10 is arranged slidably in the casing 9 and it is pivoted 11 to the base member 2. A roller 13 is fitted with bearing at the end part of the casing 9, while a roller cam path 12 is formed on the base member 2 to guide said roller 13.
To commence the chocking up procedure of the outrigger structure in base position a pressure is applied first to the working cylinder 3 to raise the shore element 1 by means of the piston 6. When the die block 10 reaches its lower end position, the shore element 1 is going to tilt and then the roller 13 revolves along the roller cam path 12 and reaches its chocking up position shown in Fig. 9. As it is shown in the drawing, a safe and regular chocking up solution could be achieved by means of a relatively simple structure.
