Definitions
- the invention relates to a rope length sensor with a housing and a Measuring rope exit for the measuring rope.
- Rope length transmitters are intended to provide a measurement signal based on a stroke or a distance deliver.
- a measuring rope is wound on a rope drum.
- the Measuring rope is attached to a part whose stroke or path is to be measured, for example on a telescopic boom of a crane. With the movement of the part the measuring cable is unwound from the cable drum against a return drive. From the when the rope drum moves, an electrical signal is obtained.
- the rope drum rotates when the measuring rope is unwound. About a thread converted this rotation into an axial movement. This ensures a defined opening and closing Processing of the measuring cable and ensures that the measuring cable is always on the same Place emerges from the housing of the cable length sensor through a measuring cable outlet.
- Such a rope length transmitter is known, for example, from EP 0 778 239 B1.
- Rope length transmitters are often used in harsh and dusty environments. Doing so dirt sticks to the measuring rope. If this dirt with the measuring rope in the Housing of the cable length sensor is retracted, it affects the function of the Rope encoder. Wetness is just as critical. If the measuring cable gets wet in the rain, then the water adhering to it is drawn into the housing with the measuring rope. Moisture condenses in the interior of the case, which does not come out of the Housing can leak. Over time, the case fills with water.
- DE-U 297 16 524.0 is a mechanical stripping device provided at the measuring cable outlet known at which dirt and moisture mechanically stripped from the measuring rope becomes.
- DE-U 92 07 212 also provides one at the measuring cable outlet mechanical scraper known.
- This stripping device consists of a or more wiper plates, which have a narrow passage opening, which encloses the measuring rope, and which foreign substances are stripped from the measuring rope.
- the Measuring rope exit can not be made so narrow that a take of Dirt and moisture from the measuring rope through the air gap between Measuring rope exit and measuring rope would be excluded.
- the invention is therefore based on the object of designing a measuring cable outlet in such a way that that the measuring rope essentially no dirt and no moisture through the Take the measuring cable outlet into the housing of the cable length sensor.
- this object is achieved by means of generating an after outward compressed air flow around the measuring rope.
- this compressed air flow is generated in that the measuring cable with Air gap is successively passed through an inner and an outer passage, a chamber is formed between the two passages and via a compressed air inlet Compressed air can be introduced into this chamber.
- Embodiments of the invention are the subject of the dependent claims.
- 1 to 3 forms an accessory, which can optionally be connected to a a cable outlet opening provided (not shown) housing a Rope length sensor can be used.
- the measuring cable outlet can of course also be one form an integral part of the housing.
- the measuring cable outlet has an attachment housing 10 which is attached by means of a flange 12 the housing of the cable length sensor can be screwed on.
- the front housing 10 has one straight, central through channel 14.
- the through channel 14 forms on the inner end face of the front housing 10 facing the cable length sensor and an extension 16 or 18 on the outer end face of the front housing.
- a rope exit piece 20 which on the housing of the Rope length sensor is attachable (or - alternatively - forms part of this housing).
- the Rope outlet piece 20 forms a sleeve which tapers conically on the outlet side and there is provided with opposite flats 22 and 24.
- Such one Rope exit piece can be seen as part of the housing in Fig. 6 of EP 0 778 239 B1.
- the Rope exit piece 20 contains a spherical bearing 26. In the spherical bearing 26 is a ball 28 stored. The ball has a diametrical passage 30. By the measuring cable 32 is passed through this passage 30.
- the front housing 10 with the Extension 16 of the through channel 14 is attached.
- a similar sleeve-shaped cable outlet piece 34 is inserted into the extension 18 and secured by a pin 35.
- the rope exit piece 34 contains a spherical one Bearing 36.
- a ball 38 is mounted in the spherical bearing 36.
- the ball 38 has a diametrical passage 40.
- the measuring cable 32 is also through the passage 40 passed through.
- a radial channel 42 opens into the chamber 41.
- the channel 42 stands with one Compressed air connection 44 in connection.
- the Drockair connection is a throttle upstream.
- the measuring cable outlet described works as follows:
- the air gap 48 formed between the passage 40 and the measuring cable 32 is somewhat larger than the air gap 50 formed between the passage 30 and the measuring cable 32. If compressed air is supplied to the compressed air connection 44 during operation, then arises predominantly a flow of compressed air through the air gap 48 reduced overpressure, which is caused by a flow divider with (not shown) upstream throttle and air gap 48 results. The reduced excess pressure also builds up inside the housing of the cable length sensor, but is not critical for the housing. By the compressed air flow around the measuring cable 32 (Fig.3) dirt and Blown wet from the measuring cable 32 when pulling in.
- the balls 28 and 38 ensure a defined guidance of the measuring cable 32 and thus a defined measured rope length if the measuring rope is inclined to the axis of the Measuring cable output is withdrawn.
- Fig.4 shows another embodiment for generating a compressed air flow on Measuring rope exit.
- FIG 4 denotes the housing of a cable length sensor. From the housing 52 a measuring cable 54 is withdrawn from a measuring cable outlet 56. The measuring cable outlet 56 is constructed similarly to the cable outlet piece 20 seated on the housing Execution of Fig.1 to 3.
- the air gap around the measuring rope 54 is advantageously somewhat wider than the air gap 50 between the measuring cable 32 and the passage 30 in Fig. 1.
- a compressed air connection 58 sits on the housing 52 Compressed air connection 58, the housing 52 can be pressurized. Compressed air flows around the measuring rope 54 out of the air gap. This airflow blows also dirt and moisture from the measuring cable 54.
- an adjustable throttle screw 60 is arranged in the compressed air connection 58. Through this throttle screw 60 the overpressure in the housing 52 can be adjusted.
- the throttle screw 60 certain throttle cross-section and the air gap at the measuring cable outlet 56 form one Current divider.
- a pressure relief valve 62 At the compressed air inlet 58 is also a pressure relief valve 62, which blows off in the case of impermissible overpressure. In this way, an inadmissible Avoided excess pressure in the housing 52, which could damage the housing 52.
