- Said hoisting machines usually consist of a crane which moves one boat at a time.

Abstract

Description
- The invention concerns a hoisting machine for the simultaneous transport to and from land and water of a number of boats.
- Presently boats are put in or pulled out of water with the aid of special cranes installed in harbours or along canals placed near the sea or lake shores, into which said navigable canals issue.
- Said hoisting machines usually consist of a crane which moves one boat at a time. Said machines are not planned to be used for emergencies, i.e. by rapidly hoisting boats and transferring them from water to land or vice versa. At the same time they are used to operate in harbours or along the containment walls of navigable canals.
- There also exist locations with miles and miles of coast with no ports or canals or other facilities such as means which can lift boats and put them in water or pull them up on land.
- For these reasons in those stetches of coast, boat users employ slides and rollers, thanks to which the difficulties encountered in transferring boats are reduced at least for small sized ones. Said lack of facilities which inhibits the presence of small fleets or fishing boats and also inhibits the development of tourism in those areas along said stretches of coast could be solved by building harbours and piers. However, this solution involves very high costs in terms of investment and maintenance. At the same time said structures, even if of small dimensions, alter considerably the landscape of the surrounding coastal area by modifying it irreversibly.
- The environmental changes, even when funds should be available, are a valid reason to stop from carrying out along the coast structures that would increase the number of fishing days a year, and the touristic and nautical development of the area.
- On the other hand, small structures that would not interfere with the currents along shores, do not supply sufficient shelter for boats in case of sudden change of weather conditions and do not allow the known means, that can be installed in these structures, to bring the boats to shore in very short time, in particular when in peak tourist periods.
- The first problem encountered on coasts which are not equipped with harbours is that of placing in the water a number of boats in a short time to give the users the opportunity of using their boats, on good fishing days or to go cruising, as much as possible, which consequently helps the development of activities in connection with the sea and tourism.
- A second problem which is also very important is to be able to pull the boats ashore when the weather changes rapidly for the worse, to avoid damages and dangerous situations for the people on board.
- The aim of the present invention is to create a fixed structure, that will not alter the natural course of the currents along the shore, and a device which operates on said structure which can simultaneously and rapidly place in the water and transport to shore several boats, in order to solve the two problems mentioned above.
- The invention that has supplied the solution to said problems consists in the combination of a fixed structure, shaped like a pier and equipped on its upper part with a slide guide, whose length extends from land to the point at sea where the depth is sufficient for the boats it transports to float, with a trolley which runs along said pier, and with at least two arms placed transversally to the said pier, supplied with hoisting devices and adequate means that are used to harness the boats, and also having a sliding counterweight saddle on said arms which are also equipped with indicating means which indicate the horizontal position of the arms, and/or of the different degrees of stress applied on the tie rod that connects the transversal arms to a central tower, with which the movement of the sliding counterweight is commanded, and having controls and means with which the hoisting devices and the other motorized parts of the machine are commanded.
- Such an invention is particularly advantageous in that it allows the trolley which slides along the pier to pick up several boats from land, to lift them and then, moving along the slide guide on the pier, move them to a distance from shore where the depth of the water is sufficient for the boats to float, then to deposit them on the water, freeing them from the harnessing means, to move up and back on land to transport another group or to remain in a stand by position waiting to recover the boats from the water.
- The lifting of the boats from the water operates in the same exact way: the boats are harnessed and hoisted from the water, then when the sliding trolley on the pier is transferred on land, the boats are lowered directly to assigned spots or onto a loading/unloading area to allow their owners to take them to the assigned spots or to take them away leaving the area free for the next lot of boats to be lifted from the water.
- The invention is particularly advantageous because it allows the transportation of several boats into the water simultaneously and in a very short time to give the users of said boats the opportunity to get the most out of their day; in the same way the invention is also advantageous for the inverse operation. This second operation is very important when it is necessary to carry it out rapidly both when it is the end of a day or because the weather changes for the worse and should the boats not be collected they could risk being damaged by the conditions of the rough seas and the danger for the people on board is easily imaginable. Another advantage obtained with this invention is due to the fact that the pier and the slide guide on it do not alter the environment, do not modify the natural flow of water currents and therefore they do not determine any corrosion of the shore in the area around the pier.
- Another advantage is the rapid dismantling of the hoisting structure, at least for routine maintenance in specifically equipped places, to ensure that safety requirements are guaranteed in time, even if it is exposed to salt water when the structure is installed on the sea.
- The invention can be easily understood in its shape and function with the aid of a detailed description herebelow and of the exemplifying drawings reproduced in the enclosed tables, in which:
- FIG. 1 is the front view of the invention in the direction in which the sliding trolley moves;
- FIG. 2 is the view from the top of the trolley with trelliss structure of the arms and one portion of the pier;
- FIG. 3 is the enlarged view of the tip of the central tower of the trolley, on which the detecting device of the horizontal position of the arms of the hoisting machine is placed;
- It is understood that the drawings are drafts and they are exemplifying to help understand the invention, without in any way being a limitation to it. The invention therefore consists in a machine with which several boats can be transported, in a short period of time, from land to sufficiently deep waters and vice versa.
- It consists of a
fixed structure 1, shaped like a pier, combined with at least atrolley 2, equipped with its own motors, operating on fuel or with electric energy from the mains or produced by specific generators, which slides alongguide 3 on the pier, which extends from land, where the boats are lifted from or left, over the water to the point where the depth of the waters is sufficient for the boats that need lifting. - The
slide guide 3, equipped with appropriate means to stop and limit the sliding of thetrolley 2, can have different shapes: from the monorail to a common track for the movement of wheels 4 oftrolley 2. - The movement is stabilized by adequate means of
reaction 5, normally formed by specific counterweights, applied ontrolley 2, on the parallel sides ofpier 1, with which the oscillations oftrolley 2 transversally to the pier are inhibited, whentransversal arms 6 and 7 should undergo unbalancing stress. - The balance of
trolley 2 is further increased by saddles placed on its sides, in positions overlooking the corresponding reaction guides anchored to thesame pier 1, which in case of a side slip oftrolley 2, would interact by blocking the tipping over sideways of thesame trolley 2. Said trolley is equipped with twoarms 6 and 7 placed on it, they are usually shaped like trellisses, mounted on rotatingplatform 8, which allows them to move from the operating position, when they are in a transversal position to pier 1, to a position in which they are lined up with the same pier, to which saidarms 6 and 7 will be anchored in the time when the machine is inactive. With saidsolution pier 1 and hoistingtrolley 2 appear like a single structure, with a minor impact on the surrounding environment. -
Arms 6 and 7, the length of each one can reach several tens of meters, are equipped withtie rod 9, which converges towardstip 10 of the central tower oftrolley 2. Its function is to discharge the weights hanging fromarms 6 and 7 to the base of thesame trolley 2 and therefore ontopier 1. At the same time said tie rod is used to activate the signal which indicates the loss of the horizontal position of the twoarms 6 and 7 or of stress imbalance on the same tie rod when the load is not balanced. The arms are usually supplied with at least onehorizontal tie rod 11 which, from a point of connection on each of saidarms 6 and 7, it converges towards the tip of ashelf 12, which protrudes fromtrolley 2 and is oriented in the example reproduced in FIG. 2, in the direction in whichpier 1 is placed. With saidtie rod 11 the stress onarms 6 and 7 is balanced out, said stress would make the arms rotate in opposite directions, for example in case of strong winds or undulating movement of the harnessed boats. - Corresponding
tie rod 9 which converges towardstip 10 of the central tower consists of a cable which slides into a groove onpulley 14, which is fixed ontip 10 of the central tower oftrolley 2. - An imbalance of the load on
arms 6 and 7 tends to cause their rotation on a vertical plane. - Said rotation, through
tie rod 9 is transmitted topulley 14, on whose axis, in the chosen solution, is applied anelement 15 which is like a pointer that rotates together with the said pulley. Saidpointer 15 is made to interact with two electric circuits. When it rotates in respect to the position of central balance, it closes one of the two circuits that activates the motor which commands the movements ofcounterweight saddle 18, until the horizontal position of the said arms and the stress balance of the two sides oftie rod 9 is not regained. The activation of one or the other electric circuit bypointer 15 commands the movement of thesliding counterweight 18 in one or the opposite direction onguides 19, housed insidearms 6 and 7, at least in the case in which the structure is a trelliss. - In order to avoid that even slight differences in the loads on
arms 6 and 7 might determine the movement of slidingcounterweight 18, the two sides oftie rod 9 converging towardstip 10 of the central tower oftrolley 2 interact with resistantelastic means 20, which are made to contrast the sliding movement oftie rod 9 and therefore the rotation on a vertical plane ofarms 6 and 7 connected to them. - In the solution reproduced in FIG. 3, said resistant
elastic means 20 are formed by springs betweenstructure 22, part of central tower oftrolley 2, andflattening lever 24 part ofpulley 14 andpointer 15 which commands the movement of slidingcounterweight 18. - The small differences in
loads 23 are therefore balanced out by the reaction of resistantelastic means 20 which contrast the rotation ofpulley 14 and therefore also the sliding oftie rod 9. The differences above a maximum limit determine the contraction of one of thesprings 20, the activation of one of the electric circuits bypointer 15, part ofpulley 14, and the subsequent movement of thesliding counterpoint 18 with which the imbalance ofloads 23 onarms 6 and 7 is balanced out. Said arms are both equipped with a series of hoistingorgans 21. Said hoisting organs are usually independent one from the other, therefore they can be activated independently from each other, so that the use of the machine is made even more flexible. - Said hoisting
organs 21, of any of the known types in a concrete solution, are distributed on the twoarms 6 and 7 and each one is in a fixed position. In such a case they can have a dimension that will allow the hoisting of bigger loads towards the central body oftrolley 2, and lighter loads by those placed towards the ends ofarms 6 and 7. - Whereas, in one other practical example the hoisting
organs 21 slide along aguide 28 which is part ofarms 6 and 7, therefore they can take on different loading positions, also in consideration of the form and dimension of theboats 23 that need to be lifted. - Each one of said hoisting
organs 21 is usually provided with its own motor to activate hoisting means 26, while in a control cabin, inside the hoisting machine or on land, there are the commands and the means for the activation of the dynamic parts of the same machine with which the controlled hoisting and releasing ofhoisting means 26 are operated, the activation of the engines that command the movement of thesliding counterweight 18 oftrolley 2 onpier 1, and also the activation of the engine that commands the rotations oftrolley 2 onplatform 8 that supports it and all those engine parts the machine will be equipped with. - When building the machine the details can be modified, as long as the functional logic of the machine is respected, as described in the following claims.
