- 1. Field of the invention
- The invention relates to a gantry crane. More particularly, the invention relates to a gantry crane for transporting track panels, comprising a longitudinal beam extending in a longitudinal direction and having lifting tools for gripping a track panel. The longitudinal beam is supported by chassis frames. Each chassis frame includes vertical beams, having vertical adjustment drives, and transverse beams connected to the vertical beams. The transverse beams extend perpendicularly to the longitudinal direction and include drives for transverse adjustment. Pairs of crawler tracks are fastened to the chassis frames for mobility of the longitudinal beam, each crawler track being connected to one of the vertical beams.
- 2. The Prior Art
- EP 0 505 240 A1 shows a gantry crane for transporting track panels. This gantry crane comprises a gantry frame which is mobile with the aid of four vertically adjustable crawler tracks. Lifting tools spaced from one another in the longitudinal direction of the frame are arranged on the gantry frame for gripping the track panel. In addition, vertically adjustable flanged rollers are provided by means of which the gantry crane is also mobile on a railroad track.
-
DE 2 309 930 A1 shows a gantry crane for laying track panels, comprising a carrying device for gripping the track panel to be transported. The gantry crane has vertically and laterally adjustable crawler tracks as well as vertically adjustable lifting rams arranged at either side thereof. Several of these gantry cranes are driven onto the laid-down track panel via flanged rollers and connected to the track panel by means of corresponding lifting tools. Subsequently, the track panel is raised by lowering the lifting rams onto the ballast bed, and the crawler track is lowered onto the ballast bed by lateral and vertical adjustment underneath the track panel. After all four lifting rams have at last been raised, the track panel is moved into the construction gap with the aid of the crawler tracks. - A track maintenance machine for exchanging a track panel is known from DE 33 40 739 A1. This track maintenance machine consists essentially of an elongated beam which, at the ends thereof, may be selectively supported on an on-track undercarriage or on a crawler track.
- It is the primary object of this invention to improve a gantry crane of the first-described type so that optimal maneuverability is assured even under spatially constricted conditions.
- This object is accomplished in accordance with the invention with a gantry crane for transporting track panels which comprises a longitudinal beam extending in a longitudinal direction. The longitudinal beam includes lifting tools for gripping a track panel and is supported by chassis frames including in each case two vertical beams, having vertical adjustment drives, and two transverse beams connected to the vertical beams. The transverse beams extend perpendicularly to the longitudinal direction and have drives for transverse adjustment. Pairs of crawler tracks are fastened to the chassis frames for mobility of the longitudinal beam, each crawler track being connected to one of the vertical beams. The present invention provides that each chassis frame is designed to be rotatable relative to the longitudinal beam by means of a vertical axis of rotation disposed centrally between the two crawler tracks and connecting the two transverse beams to the longitudinal beam.
- As a result of this structurally relatively simple configuration, mobility of the gantry crane is significantly improved, so that the picked-up track panel may be transported without problems also transversely or even obliquely to the longitudinal direction of the track. In this context, it is of particular advantage that the stability of the frame is not compromised in any way. The chassis frame is maneuverable very simply by means of variable actuation of the motive drives.
- Other benefits and features of the present invention will become apparent from the following detailed description considered in connection with the accompanying drawings. It is to be understood, however, that the drawings are designed as an illustration only and not as a definition of the limits of the invention.
- In the drawings, wherein similar reference characters denote similar elements throughout the several views:
-
FIG. 1 shows a side view of a gantry crane; -
FIG. 2 shows a cross-section according to section line II inFIG. 1 ; and -
FIG. 3 shows a schematic top view of the gantry crane. - Referring now in detail to the drawings, FIGS. 1 to 3 show a
gantry crane 1 which comprises a centrallongitudinal beam 5. Said beam extends in alongitudinal direction 2 and is connected by means of twochassis frames 24 tocrawler tracks 4. Eachchassis frame 24 is formed by twovertical beams 20 and twotransverse beams 6, the latter extending perpendicularly or at an angle to thelongitudinal direction 2. Eachchassis frame 24 is designed to be rotatable relative to thelongitudinal beam 5 by means of a vertical axis ofrotation 25 which is arranged centrally between the twocrawler tracks 4 and connects the twotransverse beams 6 to thelongitudinal beam 5. - As can be seen in
FIG. 3 , a maximum angle of rotation α±15° of thechassis frame 24 with respect to thelongitudinal direction 2 of thelongitudinal beam 5 is possible. The axis ofrotation 25 extends perpendicularly with regard to the longitudinal direction of the twotransverse beams 6. -
Power sources 7 are fastened to thelongitudinal beam 5, consisting essentially of an internal combustion engine and a hydraulic pump. In addition, guidemembers 8, spaced from one another in the longitudinal direction of the frame, are vertically adjustably mounted on thelongitudinal beam 5 and connected in each case to drives 9 for vertical adjustment. The lower end of eachguide member 8 is connected to a horizontally extendingbeam 10 which, in turn, is connected to twolifting tools 11 spaced from one another in the longitudinal direction of the beam. Eachbeam 10 is supported on saidguide member 8 for rotation about avertical axis 12. Thelifting tools 11 are designed in the known manner in the shape of clamps or hooks for form-fittingly gripping a rail head or a rail base of atrack panel 13 to be transported. - Each of the four
crawler tracks 4 consists of twoundercarriage units longitudinal direction 2 of thelongitudinal beam 5. Bothundercarriage units chassis beam 17 mounted on thevertical beam 20 for pivoting about ahorizontal axis 16 extending perpendicularly to the longitudinal direction of the frame. Eachundercarriage unit chassis beam 17 for pivoting about ahorizontal undercarriage axis 18 extending perpendicularly to the longitudinal direction of the frame. Associated with eachundercarriage unit crawler tracks 4, is aseparate motive drive 19. - The two
horizontal undercarriage axes 18 of the twoundercarriage units FIG. 2 , twodrives 9 are fastened to thelongitudinal beam 5 for vertical adjustment of eachguide member 8, respectively. Vertical adjustment drives 3 are arranged inside the two-partvertical beams 20, the latter being telescopically extendable in the vertical direction. - As can be seen in the left-hand half of
FIG. 2 , the lower ends of two of thevertical beams 20 at a time, adjustable in the vertical direction and associated in each case with acrawler track 4, are connected to one another by means of a connectingbeam 21. The saidchassis beam 17 is fastened to the connectingbeam 21 for pivoting about thehorizontal axis 16. The respective upper halves of the two two-partvertical beams 20 are connected to aguide tube 22 which is displaceably mounted within thetransverse beam 6. With the aid of atransverse adjustment drive 23, theguide tube 22, together with thevertical beams 20 and the associatedundercarriage units transverse beam 6. - In working operations for removing a
track panel 13, thegantry crane 1 is moved forward with the aid of the crawler tracks 4 on the region of the ballast bed or the earth formation laterally adjoining the laid track, until the construction gap is reached. Subsequently, thelongitudinal beam 5 together with thetransverse beams 6 is lowered by means of corresponding actuation of the vertical adjustment drives 3. Thedrives 9 are then actuated until thelifting tools 11 come to lie immediately above the rails of thetrack panel 13 to be gripped. After the saidlifting tools 11 have been form-fittingly engaged with the associated rail, thetrack panel 13 is lifted by actuation of the vertical adjustment drives 3 and the drives 9 (seeFIG. 1 ). - By actuation of the motive drives 19, the raised
track panel 13 can now be transported away. During this, better adaptation to an uneven riding surface is ensured due to the special design and mounting of the crawler tracks 4, in which theindividual undercarriage units horizontal axis 18 and thehorizontal axis 16. The expression “horizontal” refers to that situation in which thegantry crane 1 is resting on a horizontal plane. - Accordingly, while an embodiment of the present invention has been shown and described, it is obvious that many changes and modifications may be made thereunto without departing from the spirit and scope of the invention.
