Definitions
- the goal of this invention is to provide a structure of a telescopic camera crane cheap and easy to construct and easy to extend by adding extra movable arms.
- the goal meets telescopic camera crane according to the invention comprising a fixed arm with a movable counterweight and mounted on a pedestal, at least two movable arms advancing telescopically from the fixed arm and a rope-driving mechanisms for driving the movable arms.
- the rope-driving mechanism of the first movable and the next movable arms constitutes a first and a second winding drum, a first and a second rope pulley and four sections of a substantially inextensible driving rope.
- An exemplary camera crane according to the invention has one movable arm 1 having length of 4 m, accommodating three telescopically mounted movable arms 2, 3 and 4, each 3.85 m long.
- the fixed arm 1 can be mounted in any pedestal, for example on a horizontal axle, being part of the known camera crane carriage with a perpendicular column.
- Each arm (1, 2, 3 and 4) of the crane has a form of a box girder made of aluminum profiles.
- the arms are supported telescopically one within another by means of known roll guides or by means of other known linear bearing systems.
- Rope driving mechanism of the second movable arm 3 ( Fig. 3 and Fig.
- the second end of the third section 21 of the rope is fastened to the second winding drum 12, whereas to the same drum 12 there is also fastened the first end of the fourth section 23 of the rope, the second end of which (22) passes through the second rope pulley 14 and is fastened to the first movable arm (2), i.e. to the preceding arm in relation to the arm driven by the said rope sections.
- the first movable arm 2 can be moved with respect to the fixed arm 1 by means of any suitable drive.
- the arm is driven by a toothed belt 26 extended over two toothed rolls 27, one of them being driven through gear by electric motor 28.
- both the first and the second winding drum 11 and 12 respectively, that drive the third movable arm 4 are fastened onto the second movable arm 3, which is the preceding arm in relation to the said third (driven) movable arm 4.
- the first end of the first section 17 of the rope is fastened to the arm 2 that precedes the arm 3 that precedes the arm 4 which is driven by this rope assembly.
- the crane according to the invention can have both its winding drums 11 and 14 mounted in swivel fashion onto separate axles, because the drums on the axle 15 rotate only under the tension of the relevant sections of the rope and here it is essential merely that both drums that drive one arm have the same diameter.
- the partition of the rope that drives one movable arm, into four sections has merely the function to simplify assembly and to reduce the cost of the possible replacement of the damaged section of the rope.
- the first and the second rope sections (as well as the section third and fourth accordingly) of one rope-driving mechanism can be two parts of the same continuous rope. In such situation, such long continuous rope is attached in one point to its corresponding winding drum.
