Definitions

• the invention relates to a transport device according to the Merkmaien in the preamble of claim 1.
• Such a transport device is also known by the term "monorail conveyor system", in particular for use in underground mining operations.
• the locomotion of the transport train via drive units with friction wheels takes place, which are pressed against the webs of the rail sections from the sides of a guide rail formed from rail shots.
• the prior art also includes a so-called mixed operation (DE 42 20 527 A1).
• each drive unit above each friction wheel on a smaller diameter gear The friction wheels are then brought out of engagement with the webs of the rail sections of a cross-sectionally double-T-shaped guide rail, when the gears are brought into engagement with racks, which extend partially above the guide rail. Since the friction wheels are driven by hydraulic energy, different relative speeds result from each other and thus also different pressure angles of the gears, since they do not move synchronously with each other. This is also due to the different slip and cornering of the transport train. It is therefore necessary to synchronize the speeds of the gears and align them with the friction wheels.
• a transport device for persons and loads which has a transport unit, which is forcibly guided on rails.
• the transport unit comprises synchronous drives with carrying wheels, which roll on two opposite sides of an angle profile.
• the synchronous drives have gears that roll on a roller pin rail.
• the gears extend next to the carrying wheels, the roller bolt rails being mounted on the angle profiles.
• lateral guide roller pairs are provided for guiding the synchronous drives.
• the roller bolt rails each consist of a U-profile and bolts inserted between the legs of the U-profile.
• the GB 2 096 957 A discloses a transport device with a ladder-like guide rail of two longitudinal webs and between the longitudinal webs transversely incorporated sprouts. On the rungs, an impeller is moved along, which has several interacting with the rungs wings. The impeller is designed to receive loads.
• the invention is - starting from the prior art - the object of the invention to provide a transport device in which even in large loads both in soled operation as well as gradients and descents ensures proper interaction of the drive units with the guide rail and also the mechanical and hydraulic Cost of training a tractor can be minimized.
• each rail shot of the guide rail is now formed of two mutually parallel flanges and of several, the superimposed flanges interconnecting bolts.
• the drive unit of the tractor is associated with a gear which cooperates form-fitting and non-positively from one side of the guide rail with the bolt. That is, the gear rolls on the bolt.
• the tractor is supported by support rollers on the inner sides of the lower flanges of the rail shots.
• the gear preferably has a vertical central axis, that is, that the central axis is parallel to the bolt.
• the tractor can be supported laterally via support rollers on the guide rail.
• the supports are preferably on the side surface of the lower flange.
• the permanent positive engagement of the gear with the bolt also has the advantage that braking devices can be made simpler.
• the positive engagement can itself act as a brake when the drive of the gear can be set accordingly.
• Another advantage of the invention is a substantial specific increase in tensile force. For each drive unit, therefore, a higher tensile force can be transmitted. Internal tests have shown that a tensile force of 15 kN and more can be achieved, which would correspond to an increase of 50% compared to a pure friction wheel drive.
• Hydraulic pressure systems and corresponding valve means can also be omitted due to the positive power transmission between the gear and the bolt.
• the power transmission is improved according to the invention when the drive unit is associated with at least two positively co-operating with the pin gears.
• the gears may be arranged one above the other or offset in the longitudinal direction of the guide rail.
• a drive unit is provided with at least one positively acting together with the bolt gear with preferably vertical central axis.
• a further embodiment with two drive units provides that the gears are arranged offset from each other in the longitudinal direction of the guide rail, that is not in the same transverse plane.
• the gears can then lie in the same height level. Even offset elevation levels are possible.
• the tensile force is transmitted to at least two bolts. The load per bolt drops.
• the support rollers are advantageously seen in pairs in the longitudinal direction of the guide rail provided in front of the gears.
• Each gear may be under the influence of an electric, pneumatic or hydraulic drive.
• the flanges of the rail sections can be designed as flat strips. Between the flanges, the bolts are attached.
• At least the upper flanges of the rail sections are formed as hollow profiles.
• the hollow profiles have a rectangular cross-section.
• a further stiffening of the rail sections is achieved by providing reinforcing profiles on the upper flanges.
• the reinforcing profiles may be formed as in the vertical central longitudinal plane of the bolt extending web strips.
• reinforcing profiles are T-shaped and secured with the webs on the upper flanges.
• the flanges of the rail sections can also be U-shaped in cross section, with the lateral legs of the upper flanges pointing upwards and the lateral legs of the lower flanges facing downwards.
• the legs may form integral parts of the flanges. But they can also be made separately and welded to flat bars. They can have a triangular cross-section. Other cross sections are also conceivable.
• the bolts may be formed as a round bolt made of solid material. By simply cutting bar stock this is a cost effective design. The bar material does not necessarily have to be round in cross-section. The bolts can basically also have non-circular cross sections.
• the bolts can z. B. have a rectangular cross-section with rounded longitudinal edges.
• the longer axis preferably extends in the longitudinal direction of the guide rail.
• the bolt can be seen in longitudinal section elliptical or spherical designed.
• the bolts may be attached to the opposite inner sides of the flanges. More advantageous, however, is an embodiment in which the bolts are fastened in recesses adapted to their cross-section in the end sections in the flanges. This is preferably done by welding. Expediently, welding robots are used for automated welding.
• a guide rail end centering means may be provided on the undersides of the lower flange of each rail section.
• two short profile bars are arranged at a distance next to each other at one end, while at the other end a short profile bar is provided which engages in the coupling of two rail shots between the two profile bars of a following rail shot.
