Description

Roof lift system by multitorres, with ascent of the elevator car by means of a hydraulic climbing device.

Object of the invention

The object of the present invention is to define a system for lifting roofs of large surfaces; said system is composed of a set of lifting towers, a mobile lifting carriage, which moves axially driven by a hydraulic climbing equipment, inside said towers by scaling them and dragging the corresponding weight of the roof that is intended to be lifted. The system is complemented by several columns or guide towers that are located on the perimeter of the roof and that prevent the horizontal displacement of the roof, motivated by the eventual action of the wind on the surfaces to be raised during the lifting time, and ensure the
cover.

Background of the invention

The covers of large areas (ships, buildings, pavilions, sports centers, singular constructions, etc.), have been rising traditionally - as a whole or by parts- by means of cranes, good tower, good car, using these individually if the roof to be raised is low surface or weight, or in combination if it is of greater proportions

In the developed world - highly competitive, technified and identified with occupational safety parameters stand out notably in the operations of assembly: the safety of people and the minimization of Times used At first, both objectives seem opposed, or, in any case, hardly compatible. He invention presented here comes to solve this problem, joining both concepts and allowing the elevation of roofs -which have previously been mounted on the ground- in a single block, whatever the surface and weight thereof, so that human intervention is not necessary during the process of elevation and that said elevation be carried out quickly and safe. Also, the number of buildings, ships, is increasing pavilions, hangars, etc. that are covered by structures space based on concurrent bars in knots, also known as space covers, whose assembly is liable to be performed on the ground, including all systems and accessories thereof, such as straps, plates and indoor insulation, aerators, gutters, network installation of fluids and lighting under cover, etc., being able to perform elevation of the entire structure in a single block if I had the right system.

The invention presented comes to alleviate this empty, also serving multiple uses, since, a Once the cover is located, and secured against a possible fall by the system itself, above its final level, proceed to the installation of the definitive pillars, carrying out the own lifting system a smooth descent of the roof to support in the mentioned pillars. Having made this settlement, it proceeds to disassemble the towers with the help of two hoists remote control, leaving the system ready to be used New in another area to cover.

At the present time, there is no record of the existence of any device of this type whose application Direct be the elevation of decks. Systems are known and telescopic ladder devices and guided mobile elements for mounting mast modules and elements tower crane accessories, as described in the European Patent 2,179,441 and Spanish Patent 2,006,809. There is also evidence of the existence of systems for the wind turbine assembly using a climbing device by the tower of the generator itself and used to support a crane boom that allows the assembly of the rest of the elements through a system of counterweights, as can be seen in the Spanish patent 2,206,014. However, those devices and systems do not serve to lift large loads or offer a means for continuous roof elevation so that This is always secured against a possible fall.

Description of the invention

The system object of the present invention is It consists of the following fundamental elements:

one.

Lifting car : it is the device that climbs the lifting tower. This carriage is intended to run fixed races by means of a standard hydraulic cylinder and a hydraulic power station coupled to the lifting system itself so as to ensure that the hydraulic pipe lengths remain constant regardless of the lifting height. The fundamental components of the lifting carriage are therefore the following:

1.1

Hydraulic cylinder differential

1.2

Hydraulic power station, constituted by a pump group, control solenoid valves, regulating valve flow, oil tank with filter and safety valves, non-return and discharge, and connection for manual pump in case of emergency.

1.3

Wheelset with its system corresponding guidance on the lifting columns, prepared to absorb the possible bending solicitations that are present on the cylinder rod.

1.4

Safety dog set designed so that, due to the effect of the force of a spring on them, they are automatically anchored when they meet the grooves made for this purpose on a support plate of the tower elevation. In addition, and due to their design, they allow Free system upload at all times. For the descent, it is It is necessary to act on them through:

1.5

Dog rant set, made from a crank system and a drive electric or hydraulic, all or nothing type

1.6

Set of support plates that serve of support to the cylinder, leaning in turn on the guides of lift and dogs. They are divided into upper plate and bottom plate

1.7

Set of lugs for hitch of the lifting cables. It is an anchored lug system to the upper support plate that allows the cables to be anchored lifting correctly distributed according to the characteristics of the roof that is intended to be raised.

2.

Lift tower : This is the column through which the lift carriage runs. It is a column made from standard structural elements. The lifting tower has two climbing plates, grooved along its entire length with constant pitch, and in solidarity with the column, for the support of climbing and safety dogs. The design of this lifting column will be modular, being composed of the following elements:

2.1

Control module: it is a initial module, fully armed and fairing and with two missions fundamental: on the one hand, it serves as a support for the complete tower, so you will have the corresponding anchor plate and the system of posters necessary to transmit the normal or vertical forces, interspersing a plate of distribution of efforts by another, will house the control system own tower, so it will be fairing to, in this way, place the electrical plug module on the wall and relevant electronic

2.2

Secondary modules: it is about Variable length modules, which, coupled together, will give the total height of the lifting tower. It will have in its length the safety dog support plates and tracks rolling for the guide wheels in its entire length.

2.3

Closing module: it is a module shorter than secondary modules, completely armed and closing the lifting tower.

3.

Guiding columns or towers : these are columns to cancel unwanted efforts on the elevation towers, perimeter location and composed of:

3.1

Columns, perimeter location to the type roof to be raised (4)

3.2

Translation set on them monorail or similar hoist type.

3.3

Work civil, responsible for absorbing horizontal thrusts caused by  the wind, as well as some weights tied to the columns to help them in their mission.

The entire system described can be commanded through an optional control set, consisting of some or all of the following elements:

Programmable controller with outputs and inputs necessary to cover the entire range of necessary signals. Be program in such a way that automatically prevents maneuvers not planned consensual, regardless of whether your function on a touch screen.

Touch screen, which will be the interface of the user with the programmable automaton. In it, and pressing buttons window change, you can see both the information concerning to each elevation column, as the general information of the full lift It will also incorporate buttons that allow the individual manual control of each lifting column, the data printing, etc.

Print set that allows you to print a report of the complete elevation and of each of the columns to User request Also, this information should be able to be stored on another physical medium, type hard disk or similar. How Basic information will be recorded: Operator, Start time of the Lift, End time of the lift, Alarms, Warnings, Final lifting height of each column.

Protection cabinet, with protections necessary.

Continuous measurement system of the progression of elevation, which continuously contrasts the deviation setpoint between the levels reached in the different towers and that leads to a monitoring, control and command program a series of data that allow, in automatic, the correction and equalization of the cylinder runs and consequently maintain, constantly, cover in a preset position.

This entire control system will be fairing or mounted on a trailer in a modular way, so that its transport and implementation in the field is easy and fast. How obviously, you will have some tickets, labeled, for hoses that arrive from each of the towers.

Preferred Embodiment of the Invention

The operation of the lifting system will be the following (see figures 9a, 9b, 12, 13a, 13b and 13c):

First, the assembly of the lifting towers (2) necessary depending on the surface and total weight of the roof to lift. These columns will be supported directly on the ground, through its distribution backplates efforts, (2.2.1), introducing into them the car of elevation (1).

Perimeter, the towers of guidance (3) needed around the surface of the roof depending on the dimensions of it.

Once all these elements have been placed, proceed to mount the roof at ground level (Figure 13a), leaving the relevant gaps in the passage zone of the columns or lifting towers. In this way, the assembly of the covered by the personnel involved in it is done to ground level, without the need to use lifting equipment and with the consequent advantage that this implies for security and occupational health Subsequently, once located and placed in vertical all the lifting towers, we will proceed to tie the cables to the deck to be raised. These cables will go in turn anchored to the lifting lugs of the carriage (1.7).

Through an electrical / electronic equipment power to the hydraulic cylinders (1.1) of the lift car (1), so that, injecting fluid into the rear chamber of the cylinder, with the help of the hydraulic power plant (1.2) incorporated into the effect, the upper support plates (1.6.1) of the carriage (1) of all lifting towers (2) - composed of the module control (2.2), secondary modules (2.3) and closing module (2.4) - move simultaneously, running the race of the hydraulic cylinder with respect to the bottom plate (1.6.2) and causing the deck to rise that distance. Meanwhile, the climbing and safety dogs (1.4) are coupled to the slots made in the climbing plates (2.1), lashing (blocking) and unlocking (unlocking) thanks to its design. These dogs prevent the upper and lower support plates  (1.6.1 and 1.6.2) recede in your career, even in the case of a hydraulic failure, making the system always locked against the uncontrolled recoil of the cover. This movement of descent can only be allowed at the operator's will controller when unlocking safety dogs (1.4) by means of the dog raking system (1.5) in case it is necessary to lower the cover.

After completing the cylinder run in the movement described above, fluid is injected into the chamber front of it, whereby, the lower support plate (1.6.1) of the lifting carriage rises and ascends through the tower of lift a distance equal to the stroke of the cylinder (1.1) until leaving the lifting carriage (1) in its original position but raised above the lift tower (2) that distance.

At all times the lift car (1) goes guided by the wheel assemblies (1.3) that run through the raceways (2.5), installed on the lifting towers (2), which prevent the appearance of stress on the roof and that ensure a smooth climb without friction of the car (1).

Repeating the procedure described (which may see schematically in figure 12) "n" times, it manages to raise a roof type (4) "n" times the cylinder stroke (1.1), the only limitation being height lifting tower maximum (2) (figure 13b). This height maximum will depend on the number of secondary modules (2.3) that are incorporate into the tower and will be equal to or greater than the final height at the one that has to lift the cover (figure 13c).

While all movements are performed, the guided towers (3) act preventing the towers of elevation (2) influence the horizontal forces produced by wind and other small, not provided, on the deck. For this, the cover type (4) will be attached to the hoist system (3.2) and columns (3.1) will be provided, which will be located perimeter, of a civil work (3.3) and counterweights (3.4) help them resist the efforts that appear.

Once the cover is located about 200 mm. above the final level of construction, we proceed to the installation of the definitive support pillars of the same, securing them, and allowing the withdrawal of the complete system of lifting described that can be reused in later constructions.

The lifting system can be operated from automatic or manual, depending on the operator's choice, if applicable, whether or not an automatic system of control. It is not considered necessary to extend this description so that any subject matter expert understands the scope of the invention and the advantages derived therefrom. The terms in which this report has been written must be taken  always in a broad and non-limiting sense.
