Description

Technology Field

[0001] The present invention relates to continuous concrete panel laying equipment, and more specifically, to an invention that contributes to process improvement by providing continuity and speed to the laying work of replacing a ballast bed with concrete panels. Background Technology

[0002] Railway ballast is used to prevent the movement of sleepers by evenly distributing the weight of the rolling stock supported by the sleepers on the track to the roadbed, and to facilitate track drainage and track maintenance. Conventionally, ballast was generally a structure consisting of gravel laid between the ground and the sleepers.

[0003] However, while this ballast track has the advantage of evenly distributing the load transmitted through the rails to the ground during train operation, it presented a problem in that the ballast would break and wear down over time, degrading its functionality as a track. Additionally, the reduced stability of train operations necessitated frequent maintenance work, such as replenishing or replacing the ballast.

[0004] To address these issues with ballast trackbeds, concrete trackbeds have recently been constructed and used after their removal. In this process, it is required to replace the ballast trackbed with a concrete trackbed quickly and safely without interrupting train operations during the installation process.

[0005] Meanwhile, as a measure to rapidly lay rails and improve track quality, a precast concrete panel manufacturing method is being widely used recently. In this method, concrete panels are manufactured in advance at a factory using a precast process and then transported to the site, rather than producing panels (slabs) by pouring concrete on-site.

[0007] Precast concrete panels (hereinafter referred to as "concrete panels") are manufactured by curing concrete in a mold, and then removing and inverting the completed concrete panels. Subsequently, rails are attached to the concrete panels, and the concrete panels with attached rails are loaded onto a car that connects to a train. The car is then positioned near the ballast bed that needs to be removed. After the ballast bed is removed, the concrete panels are lifted using a crane or similar equipment and placed on the site of the removed ballast bed.

[0008] At this time, as shown in Fig. 11, a hole (H) is formed in the concrete panel. After the concrete panel is seated, a finishing process is required to fix the concrete panel to the ground with steel by pouring concrete into the hole (H) and allowing it to harden.

[0009] In this process, workers must be equipped with separate equipment for curing concrete, and since the equipment is very bulky, a separate cart must be provided for loading the curing equipment, which results in excessive installation costs and a long installation time, leading to a problem of very low work efficiency.

[0010] In addition, as the working ranges of the crane and the cart for loading curing equipment overlap, work efficiency decreases and the safety of workers is compromised. Furthermore, generally, the cart for loading curing equipment is placed on the ballast bed other than the one to be removed out of a pair of ballast beds to carry out the work, but there was a problem with the work flow being very inefficient.

Specific details for implementing the invention

[0022] Hereinafter, various embodiments of the present invention will be described in detail with reference to the attached drawings.

[0024] The concrete panel laying equipment according to the present invention includes a laying car (100), a conveying unit (200), a crane unit (300), and a curing unit (400).

[0025] FIG. 1 illustrates a concrete panel laying equipment according to the present invention, and more specifically, it illustrates a state in which a loading car (2) loaded with a concrete panel (1) to be laid in place of a gravel bed, which moves along a previously laid concrete panel (1), is docked to the concrete panel laying equipment.

[0026] A number of concrete panels (1) to be laid are loaded in a loading car (2) installed at the rear of a driving car in which a worker is riding, as shown in FIG. 1, and the loading car (2) moves along a pre-installed railway rail. The loading car (2) moves to the vicinity of the concrete panel laying equipment according to the present invention, and as will be described later, when docking, the car rail on the upper part of the loading car (2) and the car rail of the laying car (100) are placed on the same line and connected, and as a result, the transfer unit (200) can freely move between the car rail on the upper part of the loading car (2) and the car rail of the laying car (100), so that the concrete panels (1) loaded on the upper part of the loading car (2) can be grasped and then moved to the laying car (100).

[0028] The laying car (100), like the loading car (2), can move along a pre-installed railway rail (1, which is generally a concrete panel combined with a rail that has already been installed to replace a ballast bed). The aforementioned car rail (110) is installed along the length direction on the upper part of the laying car (100), and the transport unit (200) moves along the car rail (110). In addition, a crane unit (300) and a curing unit (400) are located on the upper part of the laying car (100), and details regarding this will be described in detail later.

[0030] FIG. 2 is an enlarged side view of the transfer unit according to the present invention, and FIG. 3 is an enlarged front view of the transfer unit according to the present invention.

[0031] The transfer unit (200) according to the present invention includes a transfer frame (210), a first transfer roller (220), a second transfer roller (230), a transfer wire (240), a transfer gripping unit (250), a transfer pulley (260), a transfer frame moving unit (270), a transfer frame motor (280), and a transfer pulley motor (290).

[0032] The transfer frame (210) is a general term for the frame body within the transfer section (200), and, as shown in FIG. 2, for example, it is formed by extending in a vertical direction and includes a vertical transfer frame spaced apart at a predetermined interval in the longitudinal direction and a planar transfer frame connecting each vertical transfer frame at the top of the vertical transfer frame.

[0033] The first transfer roller (220) is located near the planar transfer frame and is formed in multiple units spaced apart at a predetermined interval in the longitudinal direction. It rotates around an axis extending in the width direction and serves to support the transfer wire (240). Additionally, the second transfer roller (230) is coupled in conjunction with the transfer gripping part (250). It rotates around an axis extending in the width direction from the transfer gripping part (250) and is formed in multiple units spaced apart at a predetermined interval in the longitudinal direction.

[0034] One end of the transfer wire (240) is connected to the transfer pulley (260). The transfer pulley (260) is installed on a planar transfer frame and rotates by receiving power from a transfer pulley motor (290) installed on the planar transfer frame. Additionally, the transfer wire (240) is supported by contacting both the first transfer roller (220) and the second transfer roller (230).

[0035] More specifically, the transfer wire (240), which starts by extending in the longitudinal direction from the transfer pulley (260), is bent at one of the adjacent pair of first transfer rollers (220) and extended downward in the vertical direction, is located at the lower part of the first transfer roller (220) in the vertical direction, and is extended to wrap around the lower part of the second transfer roller (230) formed at the point between the adjacent pair of first transfer rollers (220) in the longitudinal direction, is extended upward again in the vertical direction from the second transfer roller (230), and is bent again at the other first transfer roller (220) and extended in the longitudinal direction, having a structure. Multiple such structures are formed in the longitudinal direction.

[0036] At this time, when the transfer pulley (260) rotates clockwise, the transfer wire (240) is released from the transfer pulley (260), and due to the structure as described above, a plurality of second transfer rollers (230) descend downward in the vertical direction as shown in FIG. 4. FIG. 4 illustrates the state of the transfer section when the transfer wire (240) is released relative to the transfer pulley (260). At this time, unlike the second transfer roller (230), the first transfer roller (220) is fixed to the planar transfer frame and rotates, so there is no movement in the vertical direction. In addition, the transfer gripping section (250) linked to the second transfer roller (230) also descends downward in the vertical direction in response.

[0037] Conversely, when the transfer pulley (260) rotates counterclockwise, the transfer wire (240) is wound onto the transfer pulley (260), and due to the structure described above, the plurality of second transfer rollers (230) are raised vertically upward. In response, the transfer gripping unit (250) linked to the second transfer rollers (230) is also raised vertically upward. As will be summarized later, through the mechanism described above, the concrete panel (1) can be gripped and loaded onto the laying car (100).

[0039] For convenience of explanation, the configuration of the concrete panel (1) is described with reference to FIG. 2. The concrete panel (1) comprises a concrete panel body (10), a plurality of holes (20) formed in the body (10), a pad (30) fastened vertically in the concrete panel body (10), and a railway rail (40) connected along the pad (30). As described above in the prior art, concrete can be cured through the plurality of holes (20) and fixed to the floor surface.

[0040] At this time, the transfer gripping part (250) grips the railway rail (40). FIG. 5 is an enlarged front view of the transfer gripping part, and the transfer gripping part (250) includes a cylinder (251) and a clamp (252). For example, the closing and unfolding operation of the clamp (252) can be performed by the hydraulic pressure of the cylinder (251). The clamp (252) includes a clamp shaft (2521), a movable clamp (2522), and a support clamp (2523). The movable clamp (2522) and the support clamp (2523) pass through the clamp shaft (2521), and the movable clamp (2522) has one point through which the clamp shaft (2521) passes and is linked to the cylinder (251) at another point. As a result, when the cylinder (251) moves to one side, it rotates clockwise with respect to the clamp axis (2521) and tilts away from the support clamp (2523) (based on the left transfer gripping part (250) of FIG. 5), and when the cylinder (251) moves in the opposite direction, it rotates counterclockwise with respect to the clamp axis (2521) and tilts away from the support clamp (2523) (state of the right transfer gripping part (250) of FIG. 5). In addition, it is preferable that a groove with a shape complementary to the railway rail (40) is formed in the transfer clamp (2522) and the support clamp (2523) so that the railway rail (40) is positioned between the transfer clamp (2522) and the support clamp (2523), and through such a structure, the entire concrete panel (1) can be transferred by gripping the railway rail (40). Due to the above structure, the railway rail (40) can be gripped by adjusting only the cylinder (251), which simplifies the structure and reduces the cost of manufacturing the equipment, and the gripping and releasing speeds are fast, which improves the work speed.

[0041] Preferably, the transfer gripping members (250) are formed as a pair and are spaced apart at a predetermined distance in the width direction, thereby allowing each of the pair of railway rails (40) spaced apart at a predetermined distance in the width direction to grip, and at the same time, one module is formed as a pair spaced apart at a predetermined distance in the length direction to grip the railway rails (40) at both ends in the length direction, thereby allowing the concrete panel (1) to be gripped stably.

[0043] Next, the transfer frame moving part (270) and the transfer frame motor (280) will be described.

[0044] The transfer frame moving part (270) includes a transfer frame fastener (271), a transfer frame chain (272), a first transfer gear (273), a second transfer gear (274), and a transfer frame wheel (275). The transfer frame motor (280) is installed at a point on the transfer frame (210) and is coupled with the transfer frame fastener (271) to provide rotational power. The transfer frame fastener (271) is coupled with the transfer frame chain (272) to receive rotational power. The transfer frame chain (272) is formed to extend vertically along the transfer frame (210), and it is preferable that the upper end is wound along the transfer frame fastener (271) and the lower end is wound along the first transfer gear (273) and coupled in a track-like manner. At this time, the first transfer gear (273) is linked to the second transfer gear (274) and the transfer frame wheel (275) linked to the second transfer gear (274), thereby enabling movement along the car rail (110). However, this is merely an example of a movement mechanism, and it may generally be designed to move along the car rail (110) by a wheel type combined with a motor.

[0046] FIG. 10 illustrates the docking process between a loading car (2) and a laying car (100). By adjusting the loading car (2), the loading car (2) is moved to the vicinity of the laying car (100). After connecting them, the worker connects a car rail-shaped connector (2b) between the car rail (2a) formed on the loading car (2) and the car rail (110) formed on the laying car (100) so that they are extended and connected. Through this, the car rail is extended, allowing the aforementioned transfer unit (200) to move along the car rail in the longitudinal direction. The transfer unit (200) moves to the loading car (2) to grasp the installed concrete panel (1), and then moves back to the laying car (100) in that state to place it on the upper surface of the laying car (100). The entire work process will be summarized and described later.

[0048] FIG. 6 is an enlarged view of the side of the crane section (300), and FIG. 7 is an enlarged view of the front of the crane section (300). Hereinafter, the configuration of the crane section (300) according to the present invention will be explained with reference to FIG. 6.

[0049] The crane unit (300) according to the present invention includes a crane support frame (310), a first crane transfer frame (320), a second crane transfer frame (330), a crane gripping unit (340), a first crane roller (350), a second crane roller (360), a first support roller (370), a second support roller (380), and a crane pulley (390).

[0050] It is preferable that the crane support frame (310) be fixedly connected to the upper surface of the laying car (100), and more preferably installed at the rear of the laying car (100), so that, as will be described later, it is easy to place the concrete panel (1) that has been grasped in place to replace the gravel ballast, and the work time is shortened. The crane support frame (310) is formed as a pair that are spaced apart at a predetermined distance in the longitudinal direction and extend in the vertical direction, and a post that extends in the vertical direction is constructed.

[0051] The first crane transfer frame (320) is located on the upper vertical side of the crane support frame (310) and has a symmetrical shape that is extended in the longitudinal direction and spaced apart in the width direction. It is also movable forward and backward in the longitudinal direction. Additionally, the second crane transfer frame (330) is located on the upper vertical side of the crane support frame (310) and is simultaneously located between the first crane transfer frames (320) that are spaced apart in the width direction as shown in FIG. 7, and is preferably located at the center in the width direction. The second crane transfer frame (330) is extended in the longitudinal direction, and as will be described later, the first crane

[0052] A second crane transfer frame wheel (3301) is formed on the second crane transfer frame (330). The second crane transfer frame wheel (3301) is connected to and moves along a specific part of the frame (indicated by the reference numeral '321') that is extended in the longitudinal direction from the first crane transfer frame (320). Accordingly, as the first crane transfer frame (320) can move forward and backward in the longitudinal direction, the second crane transfer frame (320) can also move forward and backward in the longitudinal direction in correspondence with this, and at the same time, a structure is established that allows it to move independently forward and backward in the longitudinal direction along the first crane transfer frame (320).

[0054] The movement mechanism of the first crane transfer frame (320) will be explained in more detail.

[0055] A pair of first crane transfer frame motors (M) spaced apart in the width direction are coupled to the first crane transfer frame (320), and a motor gear (M1) that is coupled thereto to receive rotational power and extends in the width direction meshes with a crane support frame gear (311) that extends along the length direction from the top of the crane support frame (310). Preferably, as an example, it is desirable to mesh in the form of a pinion gear and a rack gear. As a result, the motor gear (M1) rotates along the crane support frame gear (311) and moves in the front-to-rear length direction, and the entire first crane transfer frame (320) linked with the motor gear (M1) is formed to be capable of reciprocating motion in the front-to-rear length direction. At this time, in order to minimize the detachment of the first crane transfer frame (320) during movement in the longitudinal direction, a crane support frame rail (312) is formed extending in the longitudinal direction on the upper surface of the crane support frame (310) as an auxiliary role, and a wheel formed on the first crane transfer frame (320) is made movable along this, thereby facilitating the movement of the entire first crane transfer frame (320).

[0057] Next, the movement mechanism of the second crane transfer frame (330) will be explained in more detail.

[0058] The front of the second crane transfer frame (330) is connected to the second crane transfer frame lower wire (3822), and the rear of the second crane transfer frame (330) is connected to the second crane transfer frame upper wire (3811). Additionally, the end of the second crane transfer frame lower wire (3822) is connected to a crane pulley (390) installed at a point on the first crane transfer frame (320), and the second crane transfer frame upper wire (3811) is also connected to the crane pulley (390). As shown in FIG. 7, the second crane transfer frame lower wire (3822) is connected to one side in the width direction of the crane pulley (390), and the second crane transfer frame upper wire (3811) is connected to the other side in the width direction.

[0059] A second support roller (380) is formed between the second crane transfer frame (330) and the crane pulley (390), and the second support roller (380) is installed on the first crane transfer frame (320) and coupled so as to be rotatable about an axis in the width direction. The second support roller (380) serves to support the second crane transfer frame lower wire (3822) between the second crane transfer frame (330) and the crane pulley (390). In addition, a plurality of second auxiliary support rollers (382) are formed on the upper part of the first crane transfer frame (320) and serve to support the second crane transfer frame upper wire (3811). That is, the above configuration allows the wire to rotate by applying tension.

[0060] Accordingly, the second crane transfer frame (330) is supported and movable along a specific part of the frame (indicated by reference numeral '321') that is extended longitudinally from the first crane transfer frame (320), and at the same time moves in response to the winding and unwinding operation of the crane pulley (390). For example, when the crane pulley (390) rotates clockwise, the second crane transfer frame lower wire (3822) is wound onto the crane pulley (390), and the second crane transfer frame upper wire (3811) is unwound from the crane pulley (390). As a result, the second crane transfer frame (330), to which the second crane transfer frame lower wire (3822) and the second crane transfer frame upper wire (3811) are connected at the front and rear, moves forward in the longitudinal direction. Conversely, when the crane pulley (390) rotates counterclockwise, the second crane transfer frame (330) moves backward in the longitudinal direction.

[0061] The crane pulley (390) receives power from the crane pulley motor (391) installed on the first crane transfer frame (320).

[0063] Next, an explanation will be given regarding the crane gripping part (340) linked to the second crane transfer frame (330).

[0064] A plurality of first crane rollers (350) are coupled to the second crane transfer frame (330). The first crane rollers (350) are formed in multiple numbers, spaced apart at a predetermined interval in the longitudinal direction. They rotate around an axis extending in the width direction and serve to support the crane gripping wire (371). Additionally, the second crane rollers (360) are coupled in conjunction with the crane gripping part (340). They rotate around an axis extending in the width direction from the crane gripping part (340) and are formed in multiple numbers, spaced apart at a predetermined interval in the longitudinal direction.

[0065] One end of the crane grip wire (371) is connected to a crane grip pulley (not shown). The crane grip pulley is located near the crane pulley (390), and its depiction has been omitted due to overlapping in the drawing. The crane grip pulley is installed on the first crane transfer frame (320) and rotates by receiving power from a crane grip pulley motor (not shown) installed on the first crane transfer frame (320). Additionally, the crane grip wire (371) is supported by contacting both the first crane roller (350) and the second crane roller (360).

[0066] More specifically, the crane gripping wire (371), which starts by extending in the longitudinal direction from the crane gripping pulley, is bent at one of the adjacent pair of first crane rollers (350) to extend downward in the vertical direction, is located at the lower part of the first crane roller (350) in the vertical direction, and is extended to wrap around the lower part of the second crane roller (360) formed at the point between the adjacent pair of first crane rollers (350) in the longitudinal direction, is extended upward again in the vertical direction from the second crane roller (360), and is bent again at the other first crane roller (350) to extend in the longitudinal direction, thus having a structure. Multiple such structures are formed in the longitudinal direction.

[0067] At this time, when the crane gripping pulley rotates clockwise, the crane gripping wire (371) is released from the crane gripping pulley, and due to the structure as described above, a plurality of second crane rollers (360) descend downward in the vertical direction as shown in FIG. 9. FIG. 8 depicts the state of the crane section before the crane gripping wire is released relative to the crane gripping pulley, and FIG. 9 depicts the state of the crane section when the crane gripping wire is released relative to the crane gripping pulley.

[0068] At this time, unlike the second crane roller (360), the first crane roller (350) is fixed to the second crane transfer frame (330) and rotates, so there is no movement in the vertical direction. In addition, the crane gripping part (340) linked to the second crane roller (360) also descends downward in the vertical direction in response.

[0069] Conversely, when the crane gripping pulley rotates counterclockwise, the crane gripping wire (371) is wound onto the crane gripping pulley, and due to the structure described above, a plurality of second crane rollers (360) are raised vertically upward. In response, the crane gripping unit (340) linked to the second crane rollers (360) is also raised vertically upward. As will be summarized later, through the mechanism described above, the concrete panel (1) can be gripped and the concrete panel (1) can be placed at the location where the gravel bed replaces it.

[0070] A first support roller (370) is positioned between the crane gripping pulley and the first crane roller (350) located at the forefront, and the first support roller (370) is preferably installed on the first crane transfer frame (320) and serves to support the crane gripping wire (371) and apply tension.

[0071] It is preferable that the gripping structure of the crane gripping part (340) be the same as the structure of the transfer gripping part (250) to prevent redundant explanation.

[0073] With reference to FIG. 8, the configuration of the curing unit (400) according to the present invention will be described. The curing unit (400) is preferably located on the upper surface of the laying car (100), and preferably located at the rear in the longitudinal direction of the laying car (100) so that a worker can quickly supply concrete to the hole (20) of the concrete panel (1).

[0074] The curing unit (400) includes a hopper (410) for supplying concrete raw materials, a conveyor belt (420) connected to the hopper (410), a mixer (430) for mixing concrete raw materials and water transported via the conveyor belt (420), and a pump (440) for discharging concrete produced by the mixer (430).

[0075] The pump (440) is connected to an unillustrated hose, and the hose is positioned near the hole (20) of the aforementioned concrete panel (1) to inject concrete. Thus, by configuring the curing unit (400) to be installed on the laying car (100) as described above, the working range of the crane and the car for loading curing equipment are not overlapped, thereby increasing work efficiency and enhancing the safety of the worker. In addition, conventionally, the car for loading curing equipment is placed on the ballast bed other than the one to be removed among a pair of ballast beds to carry out the work, but since only one ballast bed needs to be utilized, there is an advantage in that the work path is very efficient.

[0077] Hereinafter, the process of installing a concrete panel and injecting concrete to fix it to the floor surface using the concrete laying equipment according to the present invention will be described.

[0078] First, the rear of the loading car (2) is docked adjacent to the front of the laying car (100), and the connector (2b) is connected to connect the car rail.

[0079] Next, the transfer unit (200) is moved along the car rail to position it on top of the concrete panel (1) loaded on the loading car (2), and the transfer gripping unit (250) is lowered vertically through the aforementioned mechanism to grip the concrete panel (1), and then the transfer gripping unit (250) is raised vertically again.

[0080] Next, the transfer unit (200) is moved again toward the laying car (100), the transfer gripping unit (250) is lowered vertically, the gripped concrete panel (1) is released to place the concrete panel (1) at the corresponding position, the transfer gripping unit (250) is raised vertically again, and then moved forward in the longitudinal direction so that the working range does not overlap with the crane unit (300). During this process, the operation of moving forward and gripping another concrete panel (1) loaded on the aforementioned loading car (2) is repeatedly performed to ensure work continuity.

[0081] Next, as shown in FIG. 6, the first crane transfer frame (320) and the second crane transfer frame (330) are moved forward in the longitudinal direction, and more specifically, the first crane transfer frame (320) and the second crane transfer frame (330) are moved so that the crane gripping part (340) is positioned on the upper vertical side of the concrete panel (1) mounted on the loading cart (2). Afterward, the crane gripping part (340) is lowered in the vertical direction, and the mounted concrete panel (1) is gripped, and the crane gripping part (340) is raised in the vertical direction.

[0082] Next, as shown in FIG. 8, the first crane transfer frame (320) and the second crane transfer frame (330) are moved in the longitudinal rearward direction, and more specifically, the first crane transfer frame (320) and the second crane transfer frame (330) are moved so that the area to be replaced with a gravel ballast is located in the vertical lower part of the concrete panel (1) held by the crane gripping part (340). Afterward, the crane gripping part (340) is lowered in the vertical direction, and the mounted concrete panel (1) is released and the concrete panel (1) is placed in the area to be replaced with a gravel ballast (the area where the gravel ballast has been removed). Subsequently, the crane gripping unit (340) is raised vertically, and when the first crane transfer frame (320) and the second crane transfer frame (330) are moved forward in the longitudinal direction as in the aforementioned step, the concrete panel (1) to be laid in the next section (to be laid in the next order in the longitudinal direction of the installed concrete panel (1)) is already loaded onto the upper surface of the loading car (2) by the transfer unit (200), and the aforementioned step is repeated by gripping it. In this process, the entire laying car (100) is moved little by little along the railway rail (40) of the newly installed concrete panel (1) toward the rear in the longitudinal direction, allowing the work to be performed repeatedly. In this way, continuous operation is provided, which can contribute to an innovative improvement in process speed.

[0083] Finally, the concrete cured in the curing section (400) is poured into the hole (20) of the installed concrete panel (1), thereby allowing the concrete to harden and the concrete panel (1) to be fully installed on the ground. Since there is no need to provide a separate rail or curing equipment nearby, everything can be done within the laying car (100) itself, which has the effect of significantly improving the work speed. In addition, since the curing section (400) is installed at the rear of the laying car (100), the advantage of being able to pour concrete quickly is also provided.

[0086] 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.
