Description

Technical Field

[0001] This utility model relates to the field of rescue equipment technology, specifically to a special gantry crane for the lifting and rescue of dual-purpose road and rail vehicles. Background Technology

[0002] Within the roundabout depot, due to the unique terrain and track design, especially the limitation of a minimum curve radius of only 25 meters, traditional shunting locomotives cannot operate effectively. To meet the shunting needs in this special environment, the depot has equipped itself with three dual-purpose road-rail cars. These cars differ significantly from traditional shunting locomotives in design, mainly in their structure, axle load, and running gear design. The dual-purpose road-rail car design allows it to switch between railway and road modes. While this feature increases its flexibility, it also brings a greater risk of derailment.

[0003] However, current technologies for re-tracking and re-tracking dual-purpose road-rail vehicles have significant limitations and cannot meet the requirements for re-tracking the entire line within the depot. In particular, there is a lack of dedicated equipment for re-tracking dual-purpose road-rail vehicles that can cover the entire line efficiently and safely, especially in sections with small curves or high derailment risk of turnouts in roundabout depots. Utility Model Content

[0004] Based on this, and to address the significant limitations of current technologies for lifting and retracing dual-purpose road-rail vehicles, which cannot meet the requirements for rerailing the entire line within a depot, one objective of this utility model is to provide a dedicated gantry crane for lifting and retracing dual-purpose road-rail vehicles. The specific technical solution is as follows:

[0005] A gantry crane for lifting and rescuing dual-purpose road and rail vehicles includes a crossbeam, a column, a base, and a support structure. One end of the column is fixedly connected to the crossbeam, and the crossbeam and the column are perpendicular to each other. The base is fixedly connected to the end of the column away from the crossbeam, and the base and the column are perpendicular to each other. The connection between the column and the base divides the base into a short seat and a long seat. One end of the support structure is fixedly connected to the column, and the end of the support structure away from the column is fixedly connected to the base.

[0006] Furthermore, the support structure includes a first diagonal brace, a second diagonal brace, and a third diagonal brace. One end of the first diagonal brace and the second diagonal brace are fixedly connected to the same side of the column. The ends of the first diagonal brace and the second diagonal brace away from the column are fixedly connected to the long seat. One end of the third diagonal brace is fixedly connected to the side of the column away from the first diagonal brace and the second diagonal brace. The end of the third diagonal brace away from the column is fixedly connected to the short seat.

[0007] Furthermore, the first diagonal brace is positioned above the second diagonal brace, and the first diagonal brace is arranged parallel to the second diagonal brace.

[0008] Furthermore, the third diagonal brace is disposed below the first diagonal brace and the second diagonal brace, and the first diagonal brace, the second diagonal brace, and the third diagonal brace have equal inclination angles with the base.

[0009] Furthermore, the inclination angles between the first, second, and third diagonal braces and the base are equal to the inclination angles between the first, second, and third diagonal braces and the column.

[0010] Furthermore, two columns are provided, each vertically fixed to both ends of the crossbeam. The two columns are symmetrically distributed about the center line of the crossbeam, and the end of each column away from the crossbeam is vertically fixed to a base.

[0011] Furthermore, the bottom of the base is provided with a track clamping structure, which includes a first right-angle clamping plate and a second right-angle clamping plate. The included angle of the first right-angle clamping plate and the second right-angle clamping plate is both directed toward the base, and the first right-angle clamping plate and the second right-angle clamping plate are fixedly connected to the base.

[0012] Furthermore, several right-angle clamps and second right-angle clamps are evenly spaced along the track direction.

[0013] Furthermore, a cross brace is provided between the crossbeam and the column, one end of the cross brace is fixedly connected to the crossbeam, and the end of the cross brace away from the crossbeam is fixedly connected to the column.

[0014] Furthermore, the connections between the crossbeam, the base, the column, and the support structure are all fixedly connected by slotted plug-in joints.

[0015] Compared to existing technologies, the advantages of this utility model are as follows: The gantry crane for lifting and rescuing dual-purpose road-rail vehicles of this utility model, by setting a crossbeam perpendicular to the column, provides accurate positioning points and guidance for lifting operations, enabling the dual-purpose road-rail vehicle to be accurately and smoothly lifted and moved. The column, serving as the vertical support structure for the gantry crane, resists horizontal forces and moments, ensuring the stability of the entire structure. The base ensures the stability of the entire structure during operation, preventing movement or overturning due to external forces. The supporting structure, as an auxiliary support component for the gantry crane, further enhances the stability of the entire structure. The connection between the column and the base divides the base into a short seat and a long seat. When lifting and rescuing the dual-purpose road-rail vehicle, the short seat is placed as close as possible to the vehicle, so that the crossbeam is suspended above the lifting point at the end of the vehicle, reducing the angle of the pull during lifting and lowering safety risks. This utility model relates to a special gantry crane for the lifting and rescue of dual-purpose road and rail vehicles. It can improve the lifting efficiency and safety of dual-purpose road and rail vehicles, adapt to complex track environments, ensure the lifting effect, and achieve efficient rerailing.

[0028] like Figures 1-5As shown in the figure, a gantry crane for lifting and rescuing dual-purpose road-rail vehicles according to one embodiment of the present invention includes a crossbeam 1, a column 2, a base 3, and a support structure 4. One end of the column 2 is fixedly connected to the crossbeam 1, and the crossbeam 1 and the column 2 are arranged perpendicularly to each other. The base 3 is fixedly connected to the end of the column 2 away from the crossbeam 1, and the base 3 and the column 2 are arranged perpendicularly to each other. The connection between the column 2 and the base 3 divides the base 3 into a short seat 31 and a long seat 32. One end of the support structure 4 is fixedly connected to the column 2, and the end of the support structure 4 away from the column 2 is fixedly connected to the base 3. By setting the crossbeam 1, which is perpendicular to the column 2, accurate positioning points and guidance are provided for lifting operations, enabling dual-purpose road-rail vehicles to be lifted and moved accurately and smoothly. By setting the column 2, as the vertical support structure 4 for the gantry crane for lifting and rescuing dual-purpose road-rail vehicles, it can resist horizontal forces and moments, ensuring the stability of the entire structure. By setting the base 3, the stability of the entire structure during operation is ensured, preventing movement or overturning due to external forces. The support structure 4, serving as an auxiliary support component for the gantry crane used for lifting and rescuing dual-purpose road-rail vehicles, further enhances the stability of the entire structure. In this embodiment, when lifting and rescuing the dual-purpose road-rail vehicle, the short seat 31 is placed as close as possible to the vehicle, so that the crossbeam 1 is suspended above the lifting point at the end of the vehicle, reducing the angle of the lifting motion and lowering safety risks.

[0029] As a preferred embodiment of this utility model, it may also have the following additional technical features: the support structure 4 includes a first diagonal brace 41, a second diagonal brace 42, and a third diagonal brace 43. One end of the first diagonal brace 41 and the second diagonal brace 42 are fixedly connected to the same side of the column 2. The ends of the first diagonal brace 41 and the second diagonal brace 42 away from the column 2 are fixedly connected to the long seat 32. One end of the third diagonal brace 43 is fixedly connected to the side of the column 2 away from the first diagonal brace 41 and the second diagonal brace 42. The end of the third diagonal brace 43 away from the column 2 is fixedly connected to the short seat 31. By setting the first diagonal brace 41, the second diagonal brace 42, and the third diagonal brace 43, additional stability and support force are provided for the gantry crane used for lifting and rescuing dual-purpose railway and highway vehicles, the connection between the column 2 and the base 3 is enhanced, and the anti-overturning ability of the entire gantry crane used for lifting and rescuing dual-purpose railway and highway vehicles is improved by dispersing stress and providing additional support points.

[0030] As a preferred embodiment of this utility model, it may also have the following additional technical features: the first diagonal brace 41 is disposed above the second diagonal brace 42, and the first diagonal brace 41 and the second diagonal brace 42 are arranged parallel to each other. The parallel and vertically distributed first diagonal brace 41 and second diagonal brace 42 form a stable triangular support system, which significantly enhances the overall rigidity of the gantry crane used for lifting and rescuing dual-purpose railway and highway vehicles, and can more effectively disperse and balance the stress in the structure, ensuring the stability of the gantry crane used for lifting and rescuing dual-purpose railway and highway vehicles during lifting operations.

[0031] As a preferred embodiment of this utility model, it may also have the following additional technical features: the third diagonal brace 43 is disposed below the first diagonal brace 41 and the second diagonal brace 42, and the inclination angles between the first diagonal brace 41, the second diagonal brace 42 and the third diagonal brace 43 and the base 3 are equal, which can better disperse the stress in the structure and form a more balanced support system.

[0032] As a preferred embodiment of this utility model, it may also have the following additional technical features: the inclination angle between the first diagonal brace 41, the second diagonal brace 42 and the third diagonal brace 43 and the base 3 is equal to the inclination angle between the first diagonal brace 41, the second diagonal brace 42 and the third diagonal brace 43 and the column 2, ensuring that the first diagonal brace 41, the second diagonal brace 42 and the third diagonal brace 43 form a balanced supporting force between the base 3 and the column 2, reducing stress concentration in the structure and improving the stability and durability of the overall structure.

[0033] As a preferred embodiment of this utility model, it may also have the following additional technical features: two columns 2 are provided, each column 2 is vertically fixedly connected to both ends of the crossbeam 1, and the two columns 2 are symmetrically distributed about the center line of the crossbeam 1. The end of each column 2 away from the crossbeam 1 is vertically fixedly connected to a base 3. In this embodiment, the two bases 3 are also symmetrically distributed about the center line of the crossbeam 1. This symmetrical layout helps to balance the stress and moment in the structure, helps to reduce stress concentration, reduces the risk of structural fatigue and damage, improves the stability of the gantry crane used for lifting and rescuing dual-purpose railway and highway vehicles during operation, and thus extends the service life of the gantry crane used for lifting and rescuing dual-purpose railway and highway vehicles.

[0034] As a preferred embodiment of this utility model, it may also have the following additional technical features: a rail clamping structure 5 is provided at the bottom of the base 3. The rail clamping structure 5 includes a first right-angle clamping plate 51 and a second right-angle clamping plate 52. The included angle of the first right-angle clamping plate 51 and the second right-angle clamping plate 52 is both directed towards the base 3. The first right-angle clamping plate 51 and the second right-angle clamping plate 52 are fixedly connected to the base 3 and can fit tightly against the rail, providing additional support for the base 3. This significantly enhances the stability of the gantry crane used for lifting and rescuing dual-purpose railway and highway vehicles during operation, prevents the gantry crane from moving or overturning due to external forces during operation, reduces safety risks during operation, and ensures the safety of personnel and equipment. Of course, in other embodiments, the first right-angle clamping plate 51 and the second right-angle clamping plate 52 can be adjusted according to the width and shape of different rails to adapt to different specifications and types of rails.

[0035] As a preferred embodiment of this utility model, it may also have the following additional technical features: several right-angle clamping plates 51 and 52 are evenly and equidistantly arranged along the track direction, providing additional support for the base 3 and significantly enhancing the stability of the gantry crane used for lifting and rescuing dual-purpose road-rail vehicles during operation. In this embodiment, the first right-angle clamping plate 51 and the second right-angle clamping plate 52 are welded to the base 3 by steel plates, and the weld process requires full welding, using welding rods with a tensile strength of J422 or higher.

[0036] As a preferred embodiment of this utility model, it may also have the following additional technical features: a cross brace 6 is provided between the crossbeam 1 and the column 2, one end of the cross brace 6 is fixedly connected to the crossbeam 1, and the end of the cross brace 6 away from the crossbeam 1 is fixedly connected to the column 2. The cross brace 6, as an additional support structure 4, can significantly enhance the overall stability of the gantry crane used for lifting and rescuing dual-purpose railway and highway vehicles. It effectively connects the crossbeam 1 and the column 2 together, forming a more robust frame, thereby improving the load-bearing capacity of the entire structure. In this embodiment, both ends of the cross brace 6 are welded to the crossbeam 1 and the column 2 at a 45° angle using steel plates, respectively. The weld process requires full welding, and the welding rod type is J422 with equivalent tensile strength or higher.

[0037] As a preferred embodiment of this utility model, it may also have the following additional technical features: the connections between the crossbeam 1, the base 3, the column 2, and the support structure 4 are all fixedly connected by slotted plug-in joints. In this embodiment, each slot is machined by hand or by machine tool. The dimensional error of each slot should be controlled within 2mm. The crossbeam 1 has an I-shaped cross-section, which includes an upper plate, a lower plate, and a waist plate. One end of the upper plate is connected to the waist plate, and the lower plate is connected to the end of the waist plate away from the upper plate. The upper plate is 50mm wide, the lower plate is 100mm wide, and the waist plate is 100mm high. Slots matching the dimensions of the crossbeam 1 are made on the column 2. Similarly, slots matching the dimensions of the column 2 and the support structure 4 are made on the base 3.

[0038] Specifically, in this embodiment, each diagonal brace is connected to the base 3 using a 12.9 grade M20*180 semi-threaded bolt, each cross brace 6, crossbeam 1 is connected to the column 2 using a 12.9 grade M20*150 semi-threaded bolt, and the track clamping structure 5 is connected to the column 2 and diagonal brace using two 12.9 grade M20*150 semi-threaded bolts.

[0039] Specifically, in this embodiment, a hand-operated trolley, a hand-operated hoist, and a lifting sling are installed on a special gantry crane for lifting and rescuing dual-purpose road-rail vehicles to operate the lifting and rescuing of the vehicles.
