Description

Cleaning device for a trolley line of a guide rail and mechanical transport device

Technical Field

The invention relates to a cleaning device for a trolley line of a guide rail. The invention also relates to a mechanical transport device for travelling on a guide rail.

Background

The trolley line is mainly used for supplying power to the mechanical transportation equipment and communicating the mechanical transportation equipment with a fixed control station of the mechanical transportation equipment, and the function of the trolley line is realized by contacting the trolley line with a carbon brush installed on the mechanical transportation equipment. The trolley line is mainly used for lifting in workshops, assembly line production, and mobile power supply of various bridge cranes, gantry cranes and electric cars at stations and docks.

In the running process of mechanical transportation equipment, relative sliding occurs between the carbon brush and the sliding contact line, the carbon brush generates dust due to abrasion, most of the dust is left in the groove of the sliding contact line, a large amount of carbon powder is accumulated in the groove as time passes, carbon deposition is even formed, poor contact or ignition between the carbon brush and the sliding contact line is caused, power supply and communication stability are affected, and further normal running of the equipment is seriously affected. Therefore, it is necessary to clean the trolley wire from the carbon deposit regularly.

At present, a carbon deposition layer of a sliding contact line is cleaned mainly by a manual polishing treatment method, but a large amount of labor and downtime are consumed for long-distance sliding contact line treatment. In addition, the contact surface of the sliding contact line and the carbon brush is positioned at the groove of the sliding contact line, so that the space is narrow, and the manual treatment effect is not ideal.

From the prior art, a method for cleaning a wiping line of a guide rail is known, in which an air pump is mounted on a mechanical transport device, the air pump being connected by means of a gas line to a suction nozzle which is fastened to a carbon brush of the mechanical transport device and which projects together with the carbon brush into a groove of the wiping line. However, in this method, only the floating carbon on the surface of the trolley wire can be cleaned by the suction nozzle and the carbon deposit layer firmly attached to the trolley wire cannot be cleaned effectively.

In addition, from the prior art, an EMS carriage transport device of the self-cleaning type is also known, which comprises a drive train set, a slave train set and a cleaning train set, wherein the cleaning train set has a dust suction device and a brush assembly. The brush component extends into the sliding contact line and the dust suction nozzles of the dust suction device are arranged on two sides of the brush component. The dust on the surface of the sliding contact line is cleaned through the hairbrush component in the moving process of the EMS trolley, and the dust raised by cleaning is sucked through the dust suction device. However, the cleaning vehicle set can only clean dust on the surface of the trolley line, and can not completely remove the carbon deposit. In addition, the position adjustment and replacement of the dust extraction and brush assembly is also very complicated in this design.

Disclosure of Invention

The object of the present invention is therefore to provide an improved cleaning device for a guide rail trolley line in relation to the prior art, which is of simple construction and has good cleaning results.

The object of the invention is achieved by a cleaning device for a trolley line of a guide rail, comprising a chassis which is mounted on the guide rail such that it can be displaced in the installed state of the cleaning device on the guide rail. The cleaning device comprises a friction wheel for cleaning the trolley line. The friction wheel can completely remove the carbon deposition layer and the oxidation layer attached to the surface of the trolley line, which cannot be realized in the scheme of cleaning by adopting the dust suction nozzle and the brush component in the prior art. The friction wheel is also fastened to the chassis by means of a transmission, by means of which the chassis' driving movement can be converted into a rotational movement of the friction wheel. In this way, it is possible to drive the friction wheel solely by the movement of the chassis by means of the transmission, so that the friction wheel can be actively rotated relative to the trolley line. That is, the rotation of the friction wheel is not caused by the friction force between the friction wheel and the trolley line surface of the guide rail, but the movement of the running gear is transmitted to the friction wheel via the mechanical transmission, causing the friction wheel to rotate actively relative to the guide rail. According to the solution of the invention, on the one hand, the active rotation of the friction wheel enables a higher cleaning efficiency than when the friction wheel is stationary or when the friction wheel is rotated by means of the friction force between the friction wheel and the trolley line surface, and on the other hand, the active rotation of the friction wheel is achieved solely by the movement of the running gear, which makes it possible to dispense with a drive for driving the friction wheel, whereby the cleaning device according to the invention is simple in construction and inexpensive. Preferably, the movement direction of the portion of the friction wheel in contact with the guide rail is the same as the travel direction of the travel mechanism during travel of the travel mechanism, whereby the relative movement speed between the friction wheel and the trolley line can be increased, which is very advantageous for further improving the cleaning efficiency.

According to one embodiment of the invention, the chassis has a main body frame which is mounted movably on guide rails by means of a plurality of guide wheels, and a pivot frame which is mounted on the main body frame by means of a vertical pivot axis and can be pivoted between a closed position and an open position, the friction wheels being fixed to the pivot frame. The friction wheel is in contact with the trolley line in the closed position of the pivoting frame and is disengaged from the trolley line in the open position of the pivoting frame. By providing a pivoting frame, the handling of the cleaning device by the user can be facilitated, and this is also very advantageous in terms of position adjustment and replacement of the friction wheel.

According to one embodiment of the invention, the main body frame has a first transmission mechanism and the pivot frame has a second transmission mechanism. The first transmission mechanism and the second transmission mechanism form the transmission device, and the friction wheel is coupled with the second transmission mechanism. The first transmission mechanism is engaged with the second transmission mechanism in the closed position of the pivoting frame, and the first transmission mechanism is disengaged from the second transmission mechanism in the open position of the pivoting frame. This embodiment makes it possible to interrupt the transmission of motion between the friction wheel and the running gear when the mechanical transport device is in operation, but without cleaning the trolley line, thereby reducing unnecessary wear of the transmission and thus increasing the service life of the cleaning device.

According to a development of the invention, the first transmission comprises a horizontal first rotary shaft which is rotatably supported on the main frame, a rotary wheel and a first bevel gear, both the rotary wheel and the first bevel gear being mounted in a rotationally fixed manner on the first rotary shaft, the rotary wheel being in contact with the upper surface of the guide rail in the mounted state of the cleaning appliance. The transmission of the movement of the chassis to the first gear of the gear is thereby achieved in a simple and reliable manner.

Advantageously, the second transmission comprises a vertical second rotational shaft and a second bevel gear, which is mounted on the second rotational shaft in a rotationally fixed manner, and on which the friction wheel is mounted. In this way, a reliable conversion of the driving movement of the driving means into a rotary movement of the friction wheel can be achieved. Preferably, the friction wheel is mounted on the second rotational axis in a positionally adjustable manner, so that it can be ensured that the friction wheel is accommodated in the groove of the trolley line in a positionally accurate manner in the closed position of the pivot frame.

According to one embodiment of the invention, the second rotary shaft comprises a first shaft part and a second shaft part, which are connected by a universal joint, the second bevel gear is mounted on the first shaft part, and the friction wheel is mounted on the second shaft part. By dividing the second rotating shaft into the first shaft part and the second shaft part and by using the universal joint to connect the first shaft part and the second shaft part in a hinged manner, the depth of the friction wheel extending into the sliding contact line can be changed without affecting the normal operation of bevel gear transmission. According to a preferred embodiment of the invention, the second shaft part is supported vertically on the pivot frame by means of at least one retaining member, which is connected to the pivot frame by means of a screw means, between which a regulating washer is provided. The second rotating shaft can be reliably supported on the pivot frame by the holding member. In addition, the depth of penetration of the friction wheel into the wiping line can be adjusted in a very simple manner by selecting adjusting shims of different thicknesses.

According to one embodiment of the invention, the friction wheel comprises a plurality of wheel discs, between which a spacer sleeve is arranged. The distance between the wheel disks can be varied by means of the spacer sleeves, so that the friction wheel of the cleaning device according to the invention can be adapted to guide rails with wiping lines of different distances.

Further, each wheel disc includes a central boss and a body of material surrounding the central boss. The wheel disc is mounted on the second shaft part with a central bushing and can thus be displaced on the second shaft part. In this way, the individual disks of the friction wheel can be positioned in a positionally accurate manner in the respective trolley line. The second shaft member has external threads, and a lock nut is mounted on each of both ends of the central shaft sleeve on the second shaft member. The wheel disc can be locked on the second shaft part through the locking nuts at the two ends. Thus, according to the aspect of the present invention, the friction wheel can be positioned at any position on the second shaft member.

The material body of the friction wheel can be high-quality nylon wires, bristles and the like according to actual requirements. If carbon deposit exists in the sliding contact line, the material body of the friction wheel is preferably selected from abrasive wires, such as alumina abrasive wires, ceramic abrasive wires, silicon carbide abrasive wires and the like. It has been found that friction wheels made of this material have the advantages of high strength, good toughness, good resilience, good wear resistance, fatigue resistance, long service life and uniform abrasive grain size, which is particularly advantageous for removing carbon deposits from trolley lines. Particularly preferably, the abrasive filaments have a particle size of 320 mesh, 400 mesh or 600 mesh.

According to one embodiment of the invention, the cleaning device comprises a suction device comprising a suction housing and an air pump. The carbon powder cleaned by the friction wheel can be sucked out in time through the suction device so as to prevent the carbon powder from being attached to the surface of the trolley line again.

According to one embodiment of the invention, the suction housing is mounted on the chassis and is connected to the air pump via a supply line. Advantageously, the air pump can be fixed to the mechanical transport device for operation on the guide rail by means of an air pump bracket. Preferably, a filter is connected to the output pipeline of the air pump, so that carbon powder in the suction air flow can be filtered out to prevent environmental pollution.

According to one embodiment of the invention, the suction housing has a plurality of suction nozzle connections, on which the suction nozzles are detachably mounted. Thereby, the number of suction nozzles can be selected in accordance with the number of trolley lines of the guide rail. The suction nozzle joint which is not required to be connected with the suction nozzle can be sealed by an air blocking piece. Preferably, the suction nozzle is rotatably mounted on the suction nozzle joint, whereby the orientation of the suction nozzle opening in the trolley line groove can be changed.

Advantageously, in the operating state of the cleaning device, the suction nozzles are arranged such that they project into the respective trolley line and the suction nozzle openings are directed towards the bottom side of the respective trolley line. After the friction wheel removes the carbon powder on the sliding contact line, the carbon powder can fall to the bottom side area of the groove of the sliding contact line due to gravity, and the design that the opening of the suction nozzle faces the bottom side of the groove can realize more effective suction of the carbon powder.

It is further advantageous if the suction nozzle of the suction housing, viewed in the direction of travel of the chassis, is arranged in front of the friction wheel. When the friction wheel rotates clockwise when viewed from above, the friction wheel can apply an impact force to the removed carbon powder along the running direction of the running mechanism, so that the carbon powder flies forwards. By arranging the suction nozzle in front of the friction wheel, the suction device can more effectively suck away the carbon powder. It is particularly advantageous if suction nozzles are provided in front of and behind the friction wheel in the direction of travel of the chassis, with the additional suction nozzle in the rear ensuring that the carbon powder not sucked off by the suction device in front is completely sucked off.

According to one embodiment of the invention, the chassis is connected to a mechanical transport device for running on the guide rail or has its own drive. Advantageously, the cleaning device comprises an additional chassis, which is connected to the chassis in an articulated manner by means of a joint. By arranging the additional running mechanism, the running of the running mechanism on the guide rail can be more stable.

According to one embodiment of the invention, the rail has an upper flange, a lower flange and a web connecting the two rails, each rail having two opposite side walls, the main body frame being supported on each side wall of the rail by means of at least one guide wheel, only one side wall of each flange being in contact with the guide wheel in the installed state of the cleaning appliance, and the side walls of the two flanges which are in contact with the guide wheel being located on different sides of the web. The running stability of the running mechanism on the guide rail can be further improved through the diagonal support.

The invention also relates to a mechanical transport device, such as a spreader, a rail vehicle or a crane, for travelling on a rail, on which the cleaning device according to the invention is mounted.

Detailed Description

Fig. 1 to 4 show perspective views of a cleaning device 1 according to the invention for a trolley line 4 of a guide rail 3 from different perspectives, wherein fig. 1 to 3 show the cleaning device 1 mounted on the guide rail 3, and fig. 4 shows the cleaning device 1 with the guide rail 3 concealed.

In order to illustrate the structure of the cleaning device 1 according to the invention more clearly, a cartesian coordinate system is shown in fig. 1 and 3, wherein the X-axis represents the longitudinal direction of the guide rail 3 or the direction of travel of the cleaning device 1, the Y-axis represents the transverse direction of the guide rail 3 and the Z-axis represents the vertical direction. Terms indicating relative positional relationships such as "upper", "lower", "inner", "outer", "front", "rear", "bottom", and "side", etc., appearing in the present application are all with respect to the mounted state of the cleaning apparatus 1 on the guide rail 3.

The cleaning device 1 comprises a chassis 2, which is mounted movably on a guide rail 3. The running gear 2 can be connected to a mechanical transport device (not shown), such as a spreader, a rail vehicle or a crane, for running on the guide rail 3, whereby the running gear 2 can be pulled into motion by the mechanical transport device. As an alternative, the chassis 2 may also have its own drive. The chassis 2 has a main body frame 9 and a pivot frame 8, the pivot frame 8 being pivotably supported on the main body frame 9 by means of a vertically oriented pivot shaft 46.

The cleaning device 1 further comprises a friction wheel 5 and a suction device 6, both the friction wheel 5 and the suction device 6 being fixed to a pivoting frame 8. By the pivoting movement of the pivoting frame 8, it is possible to selectively bring the pivoting frame 8 into abutment against the lateral wall 16 of the main body frame 9 (closed position, which is shown in fig. 1 and 3) or to bring the pivoting frame 8 away from the lateral wall 16 of the main body frame 9 (open position, which is shown in fig. 2 and 4). In the closed position of the pivoting frame 8, the friction wheel 5 and the suction nozzle 17 of the suction device 6 each project into the trolley line 4 of the guide rail 3 and can thus remove carbon powder accumulated on the trolley line by means of the friction wheel 5 and suck it out by means of the suction device 6. In the open position of the pivoting frame 8, the friction wheel 5 and the suction nozzle 17 of the suction device 6 are away from the trolley line of the guide rail and therefore the friction wheel and the suction device do not play a cleaning role. In addition, a locking means 32 is provided on the pivoting frame 8 in order to lock the pivoting frame 8 to the main body frame 9 in the closed position of the pivoting frame 8.

The suction device 6 comprises a suction housing 38 and an air pump 39, the suction housing 38 being mounted on the pivoting frame 8 and being connected to the air pump 39 by a feed line 40. The air pump 39 can be fixed to the mechanical transport device for operation on the guide rail 3 by means of an air pump bracket 41. In addition, a filter 42 is connected to the output line 30 of the air pump 39 to filter out dust from the suction airstream to prevent contamination of the environment.

Fig. 5 shows a view of the cleaning device 1 from one side along the longitudinal direction X of the guide rail 3. As is clearly visible from fig. 5, the guide rail 3 has an i-shaped cross section, the i-shaped guide rail 3 having an upper flange 13, a lower flange 14 and a web 15 connecting the two flanges, each flange having two opposite side walls 10. The body frame 9 is supported on the side walls 10 of the guide rail 3 by guide wheels 11. At least one, in the present exemplary embodiment two guide wheels 11 are associated with each side wall 10. In addition, each guide wheel 11 is assigned a vertically oriented stationary shaft 12 which is fixed to the body frame 9, the guide wheels 11 being rotatably supported on the respective stationary shaft 12. Advantageously, in the mounted state of the cleaning appliance, only one side wall 10 of each flange is in contact with the guide wheel 11, and the side walls of the two flanges that are in contact with the guide wheel 11 are located on different sides of the web 15. For example, in the present embodiment, only the left side wall of the upper flange 13 and the right side wall of the lower flange 14 are in contact with the guide wheel 11, and the right side wall of the upper flange 13 and the left side wall of the lower flange 14 are not in contact with the guide wheel 11. The running stability of the running mechanism on the guide rail can be improved through the diagonal supporting structure.

A swivel wheel 18 is also provided on the main body frame 9, which swivel wheel is fixed to the main body frame 9 by means of a horizontal first swivel axis 19 extending in the transverse direction Y of the guide rail 3. A bearing seat 20 is provided on the body frame, and the first rotary shaft 19 is rotatably mounted in a recess of the bearing seat 20 by means of a rolling bearing. When the cleaning apparatus 1 is mounted on the guide rail 3, the rotary wheels 18 are in contact with the upper surface 21 of the guide rail 3, whereby the rotary wheels 18 are rotated due to frictional force between the rotary wheels and the guide rail while the running mechanism 2 is running.

A second rotating shaft 22 (see fig. 2 and 4) extending vertically is supported on the pivot frame 8, and the friction wheel 5 is mounted on the second rotating shaft 22 (see fig. 6 and 7). A first bevel gear 23 is mounted in a rotationally fixed manner on the end of the first rotary shaft 19 facing the pivot frame 8, and a second bevel gear 24 is mounted in a rotationally fixed manner on the second rotary shaft 22. In the closed position of the pivoting frame, the first bevel gear 23 and the second bevel gear 24 mesh and thus form a bevel gear transmission, whereby the rotation of the friction wheel 5 can be caused by the rotation of the rotating wheel 18. Advantageously, the bevel gear is designed such that the direction of movement of the region of the friction wheel 5 which is in contact with the trolley line during travel of the chassis is the same as the direction of travel of the chassis, i.e. the friction wheel 5 rotates in the clockwise direction when viewed from above when the chassis is traveling to the right in fig. 1, in such a way that the speed of relative movement between the friction wheel 5 and the trolley line surface of the guide rail can be increased and the cleaning efficiency of the friction wheel can be increased.

The first rotary shaft 19, the rotary wheel 18 and the first bevel gear 23 form a first transmission mechanism, and the second rotary shaft 22 and the second bevel gear 24 form a second transmission mechanism. The first transmission mechanism is engaged with the second transmission mechanism in the closed position of the pivoting frame, and the first transmission mechanism is disengaged from the second transmission mechanism in the open position of the pivoting frame. When the first and second gear mechanisms are engaged, they form a gear mechanism of the cleaning appliance according to the invention, by means of which the driving movement of the driving mechanism can be converted into a rotational movement of the friction wheel.

The second rotating shaft 22 includes an upper first shaft member 25 and a lower second shaft member 26. The first shaft member 25 and the second shaft member 26 are connected by a universal joint 27. The second bevel gear 24 is mounted on a first shaft member 25 and the friction wheel 5 is mounted on a second shaft member 26. Two holding members 29 for holding the second shaft part 26 are provided on a side 28 (see fig. 4) of the pivot frame 8 facing the main body frame in the closed position, the two holding members 29 being arranged horizontally and each having a receiving hole for the second shaft part 26, the second shaft part 26 being rotatably supported in the holding members 29 by means of rolling bearings mounted in the receiving holes. In addition, the retaining member 29 is fixed to the pivot frame 8 by means of a threaded means 31, such as a screw, between which threaded means 31 and the side 28 of the pivot frame an adjusting shim can be provided. The depth of insertion of the friction wheel 5 in the groove of the trolley line can be varied by selecting the thickness of the adjusting shim. The articulation of the universal joint 27 with the first shaft part 25 and the second shaft part 26 enables: even if the second shaft part 26 is no longer coaxial with the first shaft part 25 due to the replacement of a shim of different thickness, the transmission of the movement from the rotor wheel 18 to the friction wheel 5 is not affected.

Furthermore, a protective cap 48 is provided on the pivot frame, and the upper end of the first shaft part 25 facing away from the second shaft part 26 is rotatably mounted on the protective cap 48 by means of bearings. The rigidity of the pivot frame can be improved by providing the protective cover, preventing deformation thereof. In addition, in the closed position of the pivot frame, both the first bevel gear 23 and the second bevel gear 24 are accommodated in the protective cover 48, thereby ensuring the safety of the operator and at the same time protecting the first bevel gear 23 and the second bevel gear 24 from external contamination or from flying stones generated when the mechanical transport equipment runs on the guide rails at high speed, so as to achieve a smooth gear action and to improve the service life of the gear transmission. In addition, a transparent viewing window 49, for example a glass window, can be provided on the pivot frame 8 and/or on the protective cover 48. Through this viewing window, the user can observe the condition of the bevel gear transmission as well as the friction wheel and the suction housing even in the closed state of the pivoting frame.

The friction wheel 5 has a plurality of discs 36 (see fig. 6 and 7). In this embodiment, a total of seven discs are shown, but other numbers of discs are possible. Between the disks 36, spacer sleeves 37 can be provided, by means of which the disk spacing of the friction wheel 5 can be adapted to the spacing of the wiping lines 4 of the guide rail 3. Each wheel disc 36 comprises a central sleeve 33 and a body of material 34 surrounding the central sleeve. The discs 36 are mounted on the second shaft part 26 via the central bushing 33, whereby the positioning of the friction wheel 5 on the second shaft part can be adjusted by moving the central bushing on the second shaft part, so that the discs 36 of the friction wheel can be positioned positionally exactly in the respective trolley line. The second shaft member 26 has a male screw, and a lock nut 35 is attached to each end of the friction wheel 5 on the second shaft member 26, and the lock nut 35 has a female screw that fits into the male screw of the second shaft member 26. The friction wheel can be reliably fixed at the target position on the second shaft member 26 by the two lock nuts 35.

The material body of the friction wheel can be high-quality nylon wires, bristles and the like according to actual requirements. If carbon deposits are in the trolley wire, the material body of the friction wheel is preferably selected from abrasive wires, such as alumina abrasive wires, ceramic abrasive wires, silicon carbide abrasive wires and the like. It has been found that friction wheels made of this material have the advantages of high strength, good toughness, good resilience, good wear resistance, fatigue resistance, long service life and uniform abrasive grain size, which is particularly advantageous for removing carbon deposits from trolley lines. It has proven particularly advantageous if the particle size of the abrasive filaments is 320, 400 or 600 mesh.

In order to achieve a more smooth running of the cleaning appliance 1 on the guide rails, an additional chassis 7 can be connected to the chassis 2. Like the chassis 2, the additional chassis 7 has a main body frame, which is supported on the guide rails 3 by means of guide wheels. The additional chassis 7 may also have a rotatable wheel which is supported on the main body frame by means of a rotational axis extending in the transverse direction Y of the guide rail 3. In this exemplary embodiment, the additional chassis 7 is connected to the chassis 2 in an articulated manner by means of a joint 47 at one end facing the chassis 2, and the additional chassis 7 can be connected to the mechanical transport device by means of a joint at the other end.

In addition, as can be seen from fig. 8, the suction housing 38 has a plurality of suction nozzle connections 43, and the suction nozzles 17 are detachably mounted on the suction nozzle connections 43. For suction nozzle connections where no suction nozzle is required to be mounted, it can be closed by means of an air lock 44. Advantageously, the suction nozzle 17 is constructed as an injection molded part or as a 3D printed component, and the suction nozzle 17 is rotatably mounted on a suction nozzle joint, whereby the orientation of the suction nozzle opening 45 (see fig. 9) in the trolley line of the guide rail can be adjusted. Advantageously, the suction nozzle 17 is arranged in the groove of the trolley line in such a way that the suction nozzle opening 45 is oriented towards the bottom side of the groove of the trolley line. After the friction wheel removes the carbon powder on the sliding contact line, the carbon powder falls to the bottom side area of the groove of the sliding contact line due to gravity, and the suction nozzle is provided with an opening facing to the bottom side of the groove, so that the carbon powder can be sucked out.

It is also advantageous for sucking out carbon powder that the suction nozzle is slightly deflected towards the friction wheel (fig. 9), for example the central axis of the suction nozzle is at an angle of 10 ° to 30 ° to the transverse direction Y of the guide rail. It is further advantageous if the suction nozzle 17 of the suction housing 38 is arranged in front of the friction wheel 5, viewed in the direction of travel L of the running gear 2. Since the friction wheel 5 rotates clockwise when viewed from above, the friction wheel will apply an impact force to the carbon powder or carbon powder particles that have been rubbed off in the traveling direction of the travel mechanism 2, so that the carbon powder or carbon powder particles fly forward. By placing the suction nozzle 17 in front of the friction wheel, the suction nozzle of the suction housing 38 can more effectively suck the toner. Particularly preferably, suction nozzles 17 are provided both in front of and behind the friction wheel 5 in the direction of travel L of the running gear 2, with the additional suction nozzle in the rear ensuring that the carbon powder not sucked by the suction nozzle 17 in the front is completely sucked off.

The above examples illustrate or describe possible embodiments of the invention, but the invention is not limited to the above embodiments. It is to be noted here that various different combinations of the individual embodiments with one another are also possible.

Finally, it is pointed out that in the figures the cleaning device parts are not shown to scale and/or enlarged and/or reduced in order to facilitate the understanding of the structure of the cleaning device according to the invention.
