Definitions

the invention relates to telescopic booms, in particular for inclined elevators with actuators consisting of cable pulls and the extension position between the first and the second telescopic section locking devices, and a pulley formed between two telescopic sections with a block and tackle rope, which is guided several times over rollers at the opposite ends of two Telescopic shots are running.
Telescopic booms in particular inclined lifts, are used in the construction industry to transport the material to the place of use at greater heights. As a rule, they do not serve to transport people.
One or more motor winches operate the ropes, which are used to control the functions.
a telescopic boom, in particular for inclined lifts, is known to the applicant, in which the transport carriage can be moved into an angled position at the end of the transport boom.
DE-OS 27 08 796.3 Here, however, it is not the last telescopic shot, but the transport trolley itself that is brought into an angled position.
a telescopic boom, in particular for inclined lifts, according to the preamble of claim 1 is known from deliveries by the applicant (DE 30 01 410.9-22).
the actuating means of the locking elements between the first and the second telescopic section can be controlled from a fixed point and consist of swiveling bodies which in turn actuate the locking cams or the like. These swiveling bodies serve to guide one or more shortenable ropes.
the pivotable bodies with the locking elements assigned to them can be the second and the following Telescopic shots must be assigned continuously to the penultimate telescopic shot.
the invention seeks to make technical progress.
the invention as characterized in claim 1, solves the problem of redesigning a telescopic boom, in particular for inclined lifts, so that with only a single rope and a single motor winch provided for this rope, all telescopic sections except for the last one any extendable positions can be locked, and also the last telescopic section can be extended and moved into any angular position.
the first telescopic section 4 of the inclined elevator 1 carries, as the actuating means 3, a motor winch 23, the cable 2 of which is a pulley rope 8 of a pulley 7, which, deflected several times via rollers 9, from the opposite ends of two adjacent telescopic sections (e.g. upper end 10 of the first 4 and beginning 16 of the second telescopic section 5 is guided back and forth via rollers 9.
a manually operated lock 6 is provided, which is brought into engagement when a predetermined or selected extension length is reached, and thus prevents a relative displacement of these two shots.
the block and tackle cable 8 could be guided from the beginning 16 of the second telescopic section 5 via the penultimate telescopic section 13 directly to the beginning 14 of the last telescopic section 15.
the pulley rope 8 is fixed (see Fig. 3, 4, 5).
the penultimate telescopic section 13 has at its outer end 12 a guide section 31 which is articulated over the axes 30 and whose guide profile 33 with its guide flanges 34 comprises the corresponding profile of the last telescopic section 15.
the last telescopic section 15 carries a corresponding articulated section 32 with the axes 30 'at its beginning 14.
the locking device 24 (see FIG. 9) is arranged such that in the locked position the joints 51, 52 with the axes 30, 30' in are approximately at the same level and are therefore released.
the last telescopic section 15 now runs against any stop, not shown, which is arranged such that the two joints 51, 52 with their parting planes 35 are in the same position (see FIG. 5) and are thus released.
any stop not shown, which is arranged such that the two joints 51, 52 with their parting planes 35 are in the same position (see FIG. 5) and are thus released.
the last telescopic section 15 swings, driven by its weight, into the desired working position.
the tackle rope 8 is tensioned so that a link 38, for example pivotable about the wheel axis 46, pivots the slide shoe 37, on which the outer rollers 57 are arranged, with the outer shot part 36 of the last telescopic shot 15, so that this again with the penultimate telescopic shot 13 is brought into an aligned position.
the last telescopic section is extended a little further via the multiple guide 50, so that the locking bolt 27 (see FIG. 9) of the lever 28 pivoted by a spring 29 is guided out of the locking latch 26, and around that heart-shaped guide piece 25 pivots.
a locking piece 55 makes this function more secure.
the lock is released.
the last Telescopic shot 15 moves into the penultimate 13, the locking bolt 27 returning to its starting position by bending a leaf spring 54.
the transport carriage 53 is moved in a known manner with the aid of an additional rope 59, which is guided over a load roller 58 arranged at the end of the last telescopic section 15 (see FIG. 4), into its end position shown in FIG. 8.
FIG. 1 A further embodiment is shown in FIG. 1.
a tensioning cable 44 as the lower chord 41, the bending stiffness of the telescopic boom can be increased so that it experiences practically no significant deflection due to its own weight and the load (trolley 53) carried on it.
the individual telescopic sections are thus easier to move against each other.
the overall construction becomes lighter.
the load weight can be increased.
the tensioning cable 44 runs from a supply tensioning roller 42 via removable spacers 40 to any attachment point on the penultimate telescopic section 13, and can be fixed by means of suitable clamping devices 43.
the supply tensioning roller 42 automatically pulls in the tensioning rope 44 when the telescopic boom is shortened.
the lock 6 and the fixed length cable sections 19 enable this function.
