PREFERRED EMBODIMENT OF THE INVENTION

(6) The constitution and characteristics of the invention can be better understood with the following description made with reference to the attached figures.

(7) As can be observed in FIG. 1, the main body (1) of the device is illustrated, formed by a vertical metal structure, in lattice or a tube, of circular section, quasi-rectangular or another structural element, equipped with a main beam (8), vertically disposed, by way of displacement rail, and at least three upper (2a), intermediate (2b) and lower (2c) self-motorized frames or trolleys, independent of each other and separately controllable, displaceable along the main beam (8) of the main body (1).

(8) Said main body (1) is shown positioned on the surface of a multisectional prefabricated concrete tower, which shows in its working wall (3) a plurality of anchoring housings (15), designed for a specific operating method that comprises a working phase and an upward or downward movement phase.

(9) The working phase comprises the anchoring to the working wall (3) of at least two of the upper (2a), intermediate (2b) or lower (2c) self-motorized frames, by means of the corresponding anchoring means (15) to the working wall (3), and the locking of vertical displacement of the upper (2a), intermediate (2b) or lower (2c) self-motorized frames, with respect to the main body (1) by means of the corresponding locking means. In this phase, the device solidly joins the main body (1) and its associated metal working structure to the working wall (3).

(10) The upward movement phase comprises twelve steps, which shall be cyclically repeated until achieving the desired working height.

(11) Likewise, the downward movement phase comprises another twelve steps, which shall be repeated until achieving the desired working height or until reaching the ground for the dismantling.

(12) FIG. 2 illustrates the main body (1) of the device, indicating the main beam (8), vertically disposed, by way of displacement rail, and the upper (2a), intermediate (2b) or lower (2c) self-motorized frames, fixed on the working wall (3), indicating an enlargement of the construction detail of any one of the upper (2a), intermediate (2b) or lower (2c) self-motorized frames. FIG. 3 shows a construction detail of any one of the upper (2a), intermediate (2b) or lower (2c) self-motorized frames, in turn comprising a sliding part (9), partially surrounding the main beam (8), a chassis (10) horizontally displaceable with respect to the sliding part (9) and an anchoring chassis (11) with capacity of rotation with respect to the displaceable chassis (10) by means of a vertically positioned shaft (12) between both.

(13) Said upper (2a), intermediate (2b) or lower (2c) self-motorized frames have means of vertical displacement with respect to the main body (1), which comprises one or several motors (4), equipped with gearboxes (5) and pinions (6) or attack gears (not illustrated), all disposed on the sliding part (9), which are connected to one or several racks (7) vertically disposed on the main beam (8) of the main body (1).

(14) Likewise the upper (2a), intermediate (2b) or lower (2c) self-motorized frames, show locking means of vertical displacement with respect to the main body (1), located in the displaceable chassis (10). These locking means can be formed by pins, bolts, wedges or any other known technical solution that prevents the movement between both parts on actuating.

(15) Likewise, the upper (2a), intermediate (2b) or lower (2c) self-motorized frames have means of horizontal displacement with respect to the working wall (3), which comprises at least two linear actuators (17), actuated by motors (20), disposed on the sides of the sliding part (9), and traversing the displaceable chassis (10) through an opening (19), and connected at their ends with the anchoring chassis (11) by means of vertically positioned rotation axes (18). These means of horizontal displacement enable both the approximation and distancing necessary for the coupling and fixing of the device to the working wall (3), and the adaptation of the distance between the device and the working wall (3) in the case that the latter is not regular, such as, for example, in the case of prefabricated concrete towers of variable section by segments. The upper (2a), intermediate (2b) or lower (2c) self-motorized frames have rotation means of the main body (1), in the horizontal plane, with respect to the working wall (3), which comprises the anchoring chassis (11), the displaceable chassis (10), the vertically positioned shaft (12) between both, and the linear actuators (17) together with the motors (20). This encourages the possibility of having a rotation of the device with respect to the working wall, especially useful when the device is associated to a crane for the assembly of prefabricated concrete towers and for the hoisting of the nacelle and blades to its upper end.

(16) It shows the motors (4), the motors (20) and the linear actuators (17), which can be of any of the types known at present, or a combination of various types, although they will preferably be of electric, pneumatic or hydraulic type.

(17) It also shows anchoring housings (15) disposed in the working wall (3), in vertical line, and these anchoring housings (15) having locking housings (16).

(18) FIG. 4 illustrates one of the upper (2a), intermediate (2b) or lower (2c) self-motorized frames, in a position rotated 90°, indicating the displaceable chassis (10) completely adhered to the sliding part (9), and with the anchoring chassis (11) parallel to the displaceable chassis (10), without rotating.

(19) FIG. 5 illustrates one of the upper (2a), intermediate (2b) or lower (2c) self-motorized frames, in a position rotated 90°, indicating the displaceable chassis (10) separate from the sliding part (9), and with the anchoring chassis (11) parallel to the displaceable chassis (10), without rotating.

(20) FIG. 6 illustrates one of the upper (2a), intermediate (2b) or lower (2c) self-motorized frames, in a position rotated 90°, indicating the displaceable chassis (10) completely adhered to the sliding part (9), and with the anchoring chassis (11) rotated with respect to the displaceable chassis (10).

(21) FIGS. 4, 5 and 6 show any one of the upper (2a), intermediate (2b) or lower (2c) self-motorized frames, which have anchoring means to the working wall consisting of a protuberance (13) of the anchoring chassis (11), equipped with one or several locking elements (14) actuable and laterally disposed on said protuberance (13), said protuberance (13) having a configuration preferably chosen from the group formed by truncated pyramid and truncated cone shape.

(22) It also shows the vertically positioned shaft (12) and the linear actuators (17) actuated by motors (20), disposed on the sides of the sliding part (9), and traversing the displaceable chassis (10) through an opening (19), and connected at their ends with the anchoring chassis (11) by means of rotation axes (18).

(23) It shows the motors (4), equipped with gearboxes (5) provided for the vertical displacement, disposed on the sliding part (9).
