Description

Technology Field

[0001] The present invention relates to a multi-purpose construction equipment for rapid improvement of track structures, and more specifically, it can grip and transport the track while simultaneously tilting it, thereby allowing the work of changing the angle of the track to be performed more easily and accurately, shortening work time and reducing costs, and significantly improving the safety of train operation. Background Technology

[0002] In modern railway systems, various technologies are being introduced to maximize the efficiency and safety of railway transportation. In particular, the use of specialized multi-purpose railway construction equipment is essential in sections requiring changes in track angles. These sections primarily occur at intersections, junctions, and areas with many curves. In these areas, tracks must be accurately laid out and adjusted to ensure the smooth movement of trains.

[0003] FIG. 1 illustrates a turnout section, which is a representative section requiring a change in the angle of the track, and the section before the change (1) and the section after the angle change (2) are illustrated as in FIG. 1.

[0005] Conventional multi-purpose railway construction equipment is primarily designed for work on straight sections, often resulting in reduced efficiency in areas requiring angle changes. Using such equipment makes it difficult to implement precise track angle adjustments, leading to increased work time and costs. Furthermore, incorrectly installed tracks can cause safety issues during train operations.

[0007] Therefore, the present invention aims to solve existing problems and present a new technical approach to increase the efficiency and safety of railway systems. Prior art literature

Specific details for implementing the invention

[0020] Hereinafter, various embodiments of the present invention will be described in detail with reference to the attached drawings.

[0022] FIG. 2 is an overall side view of a multi-purpose construction equipment according to the present invention, FIG. 3 is a front view of a multi-purpose construction equipment according to the present invention, FIG. 4 is an enlarged side view showing the vicinity of the transport device of the multi-purpose construction equipment according to the present invention, and FIG. 6 is an enlarged side view showing the vicinity of the driving winch and lifting / lowering winch of the multi-purpose construction equipment according to the present invention. Hereinafter, the configuration of the multi-purpose construction equipment according to the present invention will be explained with reference to the above drawings.

[0024] The multi-purpose construction equipment according to the present invention includes a boom case (100), a boom (200), a girder (300), a sliding bearer (400), a bearing (500), a cylinder (600), a transport device (700), and a power transmission device (800).

[0026] First, the multi-purpose construction equipment according to the present invention includes a laying car (3) that moves along a railway rail. The laying car (3) is connected to and separated on the same railway rail as a car loaded with the track (2) to be installed, and as will be described later, the track (2) is supplied from the car loaded with the track (2) and is primarily transported to the top of the laying car (3). This can be primarily transported in the longitudinal direction by a laying preparation device (W3) and a seventh wire (70) as shown in FIG. 2. The laying preparation device is preferably in the form of a winch.

[0028] The boom case (100) is located on the upper vertical side of the movable car (3) and is formed to extend in the longitudinal direction. The boom case (100) includes a hollow portion inside, and the boom case (100) is connected to the movable car (3) in a frame shape, but is not limited to any single frame shape.

[0030] The boom (200) is formed to extend in the longitudinal direction and, referring to FIG. 3, is located inside the boom case (100). Additionally, the boom (200) is capable of reciprocating in the longitudinal direction along the boom case (100). The cross-section of the boom (200) preferably has an open lower end and a hollow portion formed therein, and preferably is a 'C'-shaped beam.

[0031] At this time, the boom (200) and the boom case (100) are linked by a power transmission device (800) as shown in FIG. 2, and preferably linked in the form of a rack-pinion gear combination. Accordingly, the boom (200) can move along the boom case (100) in the longitudinal direction by the motor, and the rack-pinion gear transmits power and guides the direction of movement.

[0033] A part of the transport device (700) is located on the inner side of the boom (200). The configuration of the transport device (700) will be described in detail with reference to FIG. 4.

[0034] The transport device (700) includes a first transport car (710), a second transport car (720), a transport platform (730), and a gripper (740).

[0035] The first transfer car (710) and the second transfer car (720) are capable of reciprocating in the longitudinal direction along the boom (200) inside the boom (200). Additionally, the first transfer car (710) and the second transfer car (720) are spaced apart at a predetermined distance in the longitudinal direction, and the first transfer car (710) and the second transfer car (720) are connected by a fourth wire (40).

[0036] The first transfer car (710) and the second transfer car (720) can be moved in the longitudinal direction by the driving winch (W1). Refer to FIGS. 6 and FIGS. 7 together. FIGS. 7 shows the driving winch (W1) viewed from the front.

[0037] The driving winches (W1) are formed as a pair spaced apart in the width direction. Additionally, it is preferable that the driving winches (W1) be positioned at the front of the boom (200) in the longitudinal direction. A driving wire (hereinafter assumed to be the third wire (30)) starting from one of the driving winches (W1) passes through a tensioner (T1) and is supported by an idler roller (I) installed at the bottom of the boom (200), and is formed to extend longitudinally along the rear of the boom (200) where the first transfer car (710) and the second transfer car (720) are located. At this time, the third wire (30) wraps around the second auxiliary roller (202) located at the rearmost end of the boom (200), reverses its direction, and is coupled to the rear end of the second transfer car (720).

[0038] The driving wire (hereinafter referred to as the third auxiliary wire (31) starting from another driving winch (W1) passes through the tensioner (T2) and moves toward the front of the boom (200), wraps around the second auxiliary roller (202) installed at the very front of the boom (200) and reverses its direction, extends in the longitudinal direction, and is connected to the front end of the first transfer car (710).

[0039] Due to the above configuration, the first transfer car (710) and the second transfer car (720) move together in the longitudinal direction toward the front or rear of the boom (200) depending on the rotation direction of the driving winch (W1).

[0041] The transfer platform (730) moves up and down in a vertical direction based on the first transfer car (710) and the second transfer car (720). To explain the principle of moving up and down, the detailed configuration of the first transfer car (710) and the second transfer car (720), and the combined structure of the first lifting / lowering wire (50) and the second lifting / lowering wire (60) will be explained.

[0042] The first transfer car (710) includes a first transfer car body (711), three first transfer car upper rollers (712), and two first transfer car lower rollers (713).

[0043] A hollow portion is formed in the center of the first transfer carbon body (711), and the three aforementioned first transfer car upper rollers (712) are installed spaced apart at a predetermined interval in the longitudinal direction. Accordingly, the first transfer car upper rollers (712) are rotated with a rotation axis coupled to the center of the first transfer carbon body (711).

[0044] Additionally, the first transfer car lower roller (713) is located below the first transfer car upper roller (712) in the vertical direction. More specifically, the first transfer car lower roller (713) is positioned with respect to the length direction between a pair of first transfer car upper rollers (712) adjacent in the length direction.

[0045] The first transfer car lower roller (713) is rotatably inserted and coupled to the transfer platform (730). A pair of hollow sections spaced apart in the longitudinal direction are formed in the transfer platform (730), and the first transfer car lower roller (713) and the second transfer car lower roller (723) are rotatably inserted and coupled to each of the hollow sections.

[0046] The first lifting / lowering wire (50) and the second lifting / lowering wire (60) are connected to the first transfer car (710) and the second transfer car (720), respectively. Details regarding this will be explained.

[0047] The first lifting / lowering wire (50) is connected to the lifting / lowering winch (W2). The lifting / lowering winch (W2) is formed in multiple numbers, and the first lifting / lowering wire (50) is connected to one of the lifting / lowering winches (W2). FIG. 8 shows a front view of the lifting / lowering winch (W2).

[0048] The first lifting wire (50), which starts from the lifting winch (W2), is formed to extend forward of the boom (200) and then reverses based on the second auxiliary roller (202) (the second auxiliary roller (202) may be formed in multiple numbers and spaced apart in the width direction, and each may be independently provided so that the third wire (30) and the first lifting wire (50) can be independently wound onto the second auxiliary roller (202)), and is formed to extend backward of the boom (200).

[0049] The first lifting / lowering wire (50) is sequentially wound onto the first transfer car upper roller (712) located furthest forward among the three first transfer car upper rollers (712), the first transfer car lower roller (713) located furthest forward among the two first transfer car lower rollers (713), the first transfer car upper roller (712) located second among the three first transfer car upper rollers (712), the first transfer car lower roller (713) located second among the two first transfer car lower rollers (713), and the first transfer car upper roller (712) located third among the three first transfer car upper rollers (712), and is formed to extend backward in the longitudinal direction. Afterwards, the direction is changed based on the first auxiliary roller (201) formed on the boom (200), and is finally connected to the connector (102) formed at the rear of the boom case (100).

[0050] At this time, the second lifting / lowering wire (60) is formed by extending through the first transfer car (710) from the upper vertical direction of the first transfer car (710), and is wound on the second transfer car (720) by the same principle as the first lifting / lowering wire (50) is wound on the second transfer car (720). The explanation regarding the winding principle of the second lifting / lowering wire (60) is redundant and will be omitted.

[0051] The second lifting / lowering wire (60) starts from another lifting / lowering winch (W2), is wound onto the second transfer car (720) by the same principle as the first lifting / lowering wire (50), is turned with respect to the first auxiliary roller (201), and is finally connected to the connector (102) formed at the rear of the boom case (100). It is preferable that the first auxiliary roller (210) be formed as a pair in the width direction, and the first lifting / lowering wire (50) and the second lifting / lowering wire (60) are wound onto each.

[0052] Due to the above configuration, when the lifting / lowering winch (W2) rotates in one direction, the first lifting / lowering wire (50) and the second lifting / lowering wire (60) raise the conveyor (730) upward in the vertical direction, and when it rotates in the opposite direction, the first lifting / lowering wire (50) and the second lifting / lowering wire (60) lower the conveyor (730) downward in the vertical direction.

[0054] A gripping member (740) is attached to the front and rear of the transporter (730), and the gripping member (740) grips the track (2). As a result, when the transporter (730) moves up and down, the track (2) also moves up and down in response.

[0056] Below, a configuration for tilting the track (2) will be described. Refer to FIG. 3 and FIG. 5 together.

[0057] A girder (300) is formed extending in the width direction at a point at the rear of the boom case (100). More preferably, the girder (300) is formed extending in the width direction between a pair of posts.

[0058] The girder (300) is in the shape of a beam extending in the width direction, and the sliding bearer (400) is in the shape of a box with a hollow portion and open sides in the width direction, and is formed to wrap around the girder (300) as shown in FIG. 5.

[0059] A bearing (500) is attached to the upper part of the girder (300), and a boom case (100) is attached to the upper part of the bearing (500). Additionally, cylinders (600) are attached to both sides in the longitudinal direction of the sliding bearer (400). Based on FIG. 5, the other end of the first cylinder (610), one end of which is attached to one side of the sliding bearer (400), is attached to a point in the front direction of the girder (300), and the other end of the second cylinder (620), one end of which is attached to the other side of the sliding bearer (400), is attached to a point in the rear direction of the girder (300).

[0060] In FIG. 5, the first cylinder (610) or the second cylinder (620) is shown coupled to only one side or the other side of the sliding bearer (400) to clearly express the tilting state, but the first cylinder (610) and the second cylinder (620) are coupled to each of the one side and the other side of each of the three sliding bearers (400) shown. In addition, the sliding bearer (400) does not move in the width direction along the girder (300) and is only capable of tilting; FIG. 5 is merely divided in the width direction to express the tilting state.

[0062] Additionally, it is preferable that the sliding bearer (400) is spaced apart at a predetermined distance on both sides in the width direction from the girder (300), and that the upper and lower sides in the vertical direction of the sliding bearer (400) are in contact with the girder (300) and move. Due to this structure, a structure is formed in which the sliding bearer (400) can tilt.

[0063] Therefore, although not shown, when a pair of cylinders (600) are stretched or contracted by a control device, a structure is formed in which the sliding bearer (400) is pushed and pulled due to the stretching or contracting action of the cylinders (600) and a structure in which a spaced-apart space is formed between the sliding bearer (400) and the girder (300) in the width direction, so that the sliding bearer (400) is tilted around the girder (300), and a structure is formed in which the boom case (100), which is linked through the sliding bearer (400) and the bearing (500), tilts together with the tilting of the sliding bearer (400).

[0064] Additionally, as the boom case (100) is tilted, the boom arm (200) supported by the boom case (100) is also tilted, and the transport device (700) linked to the boom arm (200) is also tilted, so that the track (2) held by the transport arm (730) and the gripping member (740) of the transport device (700) is also tilted, thereby forming a structure.

[0065] Due to the tilting structure by the cylinder (600) as described above, the tilting angle can be precisely controlled, and there is an advantage of significantly increasing the speed of work for track arrangement in sections where a change in the angle of the track is required.

[0067] Meanwhile, a front wing frame (12) and a rear wing frame (10) are formed at the front and rear of the boom case (100) in the longitudinal direction, respectively. The front wing frame (12) and the rear wing frame (10) can be tilted outward by control to prevent the track (2) from getting caught on the end of the boom case (100) due to the width of the track (2) in the width direction when the track (2) is held and moved along the longitudinal direction of the boom case (100). That is, by tilting, the wing frames (10, 12) perform the function of securing the space necessary when the transport device (700) holds the track (2) and passes inside the boom case (100).

[0069] Hereinafter, the operation steps of the multi-purpose construction equipment according to the present invention will be described with reference to FIGS. 9 to 18. FIGS. 9 to 18 briefly illustrate only the minimum configurations to explain the operation steps.

[0070] First, FIG. 9 illustrates the situation immediately before the track (2) is transferred to the laying car (3) by the laying preparation device (W3), and FIG. 10 illustrates the state in which the track (2) has been moved to the laying car (3).

[0071] Next, FIG. 11 illustrates the front wing frame (12) and the rear wing frame (10) in a tilted and open state.

[0072] Next, FIG. 12 illustrates the boom (200) moving from the rear to the front in the longitudinal direction. As previously described, power is preferably provided by a power transmission device (800).

[0073] Next, FIG. 13 illustrates the transport device (700) moving from the rear to the front in the longitudinal direction.

[0074] Next, FIG. 14 illustrates the transfer platform (730) of the transport device (700) descending in a vertical direction downward, the gripping member (740) formed on the transfer platform (730) gripping the track (2), and then the transfer platform (730) ascending again in a vertical direction upward.

[0075] Next, FIG. 15 illustrates the transfer platform (730) of the transport device (700) moving from the front to the rear in the longitudinal direction, and FIG. 16 illustrates the transfer platform (730) moved to the position of the track (2) to be installed.

[0076] Next, FIG. 17 illustrates the boom case (100), boom arm (200), and transfer arm (730) all tilted at the same angle due to the tilting of the sliding bearer (400) as described above, and it was previously stated that this is controlled according to the tilting angle to be installed.

[0077] Finally, FIG. 18 illustrates the state in which the conveyor (730) of the transport device (700) descends vertically downwards and the track (2) is installed.

[0078] Afterwards, the aforementioned process is reversed to return to the initial state, and the work can be repeated.

[0080] Furthermore, although preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the specific embodiments described above. It is understood that various modifications can be made by those skilled in the art without departing from the essence of the invention as claimed in the claims, and such modifications should not be understood individually from the technical spirit or perspective of the present invention.
