Description

Technical Field

[0001] This invention belongs to the field of railway emergency repair and construction technology, and in particular relates to an emergency repair equipment for beam bridges. Background Technology

[0002] Currently, the main types of emergency repair equipment for railway bridges in China include Type 64 railway military beams, modular trusses, Type 87 railway emergency repair steel beams, Type 83 railway light military bridge piers, Type 65 railway military bridge piers, railway emergency repair high piers, railway low-height construction temporary beams, and railway general temporary beams.

[0003] However, the aforementioned equipment and components are diverse, resulting in a large workload for assembly. Furthermore, the assembly methods primarily rely on on-site manual labor, with low levels of mechanization and automation. This leads to high assembly difficulty and slow speed, resulting in low construction efficiency and consequently, longer maintenance windows (a "maintenance window" refers to a period of time in the railway operating schedule specifically reserved for construction, maintenance, and inspection work, during which no trains are running). Additionally, when the section of track being repaired is located at a high altitude, the safety of the repair workers is also threatened. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides an emergency repair equipment for beam bridges, thereby solving the technical problems.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the main technical solutions adopted by the present invention include:

[0008] On one hand, embodiments of the present invention provide an emergency repair equipment for beam bridges, including an erection unit and a transport unit, both operating on the bridge to be repaired. The erection unit is connected in front of the transport unit so that the transport unit can push the erection unit to run synchronously. The transport unit is used to transport repair equipment, and the erection unit is used to assemble the repair equipment. The erection unit includes a main beam, a first outrigger, a second outrigger, a third outrigger, a first four-axle bogie, and a second four-axle bogie. The first, second, and third outriggers are arranged sequentially on the main beam from front to back. The first four-axle bogie, as a load-bearing wheel, can be connected to the underside of the first or second outrigger, and the second four-axle bogie, as a load-bearing wheel, is always connected to the underside of the third outrigger. The transport unit includes several flatcars connected in sequence. The flatcars are used to load repair equipment. The erection unit is connected to the flatcars and the transport unit through a coupler on the second four-axle bogie to receive the repair equipment from the transport unit.

[0009] Furthermore, the erection unit also includes a zero-leg support, which consists of a basic section and a movable section. The basic section is hinged to the head end of the main beam, and the movable section is loaded onto a flatcar along with the emergency repair equipment. The emergency repair equipment includes multiple emergency repair piers, which are installed vertically in front of the bridge emergency repair section. The movable section is a telescopic structure, allowing the upper and lower ends of the movable section to be connected to the bottom end of the basic section and the top of the emergency repair pier, respectively.

[0010] Furthermore, the No. 1 outrigger and the first four-axle bogie can be connected via a support beam; the support beam can be connected to the first four-axle bogie via a pin and is set above the first four-axle bogie. The No. 1 outrigger is a telescopic structure that passes through the main beam, and the lower end of the No. 1 outrigger can extend downwards out of the main beam and insert into the support beam and be detachably fixed to the support beam.

[0011] Furthermore, the erection unit also includes two lifting trolleys. Racks are installed on the outer sides of the lower ear beams on both sides of the main beam. The racks are arranged along the length of the lower ear beams. Both lifting trolleys are hung upside down on the lower ear beams and their own gears mesh with the racks to enable the lifting trolleys to move along the main beam. The emergency repair equipment also includes multiple emergency repair beams. The two lifting trolleys can connect to both ends of the emergency repair beams to lift them up.

[0012] Furthermore, the erection unit also includes a hoisting trolley, which is inverted on the lower ear beam and can move along the main beam through its own gears and racks; the hoisting trolley is used to lift emergency repair piers, beam supports and movable sections.

[0013] Furthermore, the erection unit also includes a platform, which is fixed between the second and third outriggers. The platform is used to receive emergency repair equipment and movable sections transported from the flatcar.

[0014] Furthermore, the transport unit also includes two trolleys that can move between the platform and the flatcar to transport repair equipment and movable parts from the flatcar to the platform.

[0015] Furthermore, the second outrigger includes four first rotatable multi-stage sleeves, a first upper crossbeam, a first lower crossbeam, a second lower crossbeam, and a first support leg. The first rotatable multi-stage sleeves are C-shaped and their vertical parts are telescopic. Two first rotatable multi-stage sleeves are a pair. The upper ends of the two pairs of first rotatable multi-stage sleeves are rotatably connected to the first upper crossbeam and are located on both sides of the first upper crossbeam. The lower ends of the two pairs of first rotatable multi-stage sleeves are rotatably connected to the first lower crossbeam and are located on both sides of the first lower crossbeam. The second lower crossbeam is located below the first lower crossbeam and is movably connected to the first lower crossbeam. The first support leg is fixed below the second lower crossbeam. The second outrigger is sleeved on the outside of the main beam so that the two pairs of first rotatable multi-stage sleeves are located on both sides of the main beam. The upper cover plate of the main beam is bolted to the first upper crossbeam.

[0016] Furthermore, the third outrigger includes four second rotatable multi-stage sleeves, a second upper crossbeam, a third lower crossbeam, and a second support leg. The second rotatable multi-stage sleeves are C-shaped and their vertical parts are telescopic. Two second rotatable multi-stage sleeves form a pair. The upper ends of both pairs of second rotatable multi-stage sleeves are rotatably connected to the second upper crossbeam and are located on both sides of the second upper crossbeam. The lower ends of both pairs of second rotatable multi-stage sleeves are rotatably connected to the third lower crossbeam and are located on both sides of the third lower crossbeam. The second support leg is fixed below the third lower crossbeam. The third outrigger is sleeved on the outside of the main beam so that the two pairs of second rotatable multi-stage sleeves are located on both sides of the main beam. The upper cover plate of the main beam is bolted to the second upper crossbeam.

[0017] On the other hand, embodiments of the present invention also provide an emergency repair construction method for beam bridges, comprising the following steps:

[0018] S1: The No. 1 outrigger extends, while the No. 2 and No. 3 outriggers are retracted. The first four-axle bogie is connected to the bottom of the No. 1 outrigger as a load-bearing wheel, and the second four-axle bogie is connected to the bottom of the No. 3 outrigger as a load-bearing wheel. The beam bridge emergency repair equipment stops when it reaches the bridge repair section.

[0019] S2: Support legs number two and number three rotate;

[0020] S3: The No. 1 outrigger retracts into the main beam and disengages from the first four-axle bogie, and the first four-axle bogie is connected to the bottom of the No. 2 outrigger as a load-bearing wheel.

[0021] S4: Outriggers No. 2 and No. 3 are deployed and supporting the bridge surface;

[0022] S5: Transport the emergency repair equipment on the flatcar to the erection unit in sequence and assemble it.

[0023] (III) Beneficial Effects

[0024] The beneficial effects of this invention are:

[0025] This invention discloses an emergency repair equipment and construction method for beam bridges. It includes an erection unit for assembling the repair equipment and a transportation unit for transporting the equipment. The process of transporting the repair equipment to the bridge repair section is the transportation state of the emergency repair equipment, while the process of assembling the equipment is the erection state. In the transportation state, the first four-axle bogie acts as a load-bearing wheel connected to the bottom of the first outrigger. In the erection state, the first four-axle bogie is pulled backward to the second outrigger by a wire rope generated by a winch installed in the second four-axle bogie, and then acts as a load-bearing wheel connected to the bottom of the second outrigger. The second four-axle bogie always acts as a load-bearing wheel connected to the bottom of the third outrigger.

[0026] Compared to existing technologies, this invention achieves a system transformation from long-distance transportation to short-distance erection through the displacement of the first four-axle bogie. This allows the equipment to adapt to both tight-curve transportation needs and emergency repair erection. Furthermore, by directly employing mechanical construction instead of manual labor, the amount of assembly is reduced, significantly decreasing on-site construction difficulty and intensity, thus achieving higher construction efficiency.

[0042] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0043] like Figure 1-10 As shown, the present invention provides an emergency repair device for beam bridges, such as... Figure 7-10 As shown, the system includes an erection unit 1 and a transport unit 2, both operating on the bridge to be repaired. The erection unit 1 is connected to the front of the transport unit 2, enabling the transport unit 2 to push the erection unit 1 synchronously. The transport unit 2 is used to transport the emergency repair equipment 3, and the erection unit 1 is used to assemble the emergency repair equipment 3. The process of transporting the emergency repair equipment 3 to the bridge repair section 4 represents the transport state of the beam bridge emergency repair equipment, and the process of assembling the emergency repair equipment 3 represents the erection state of the beam bridge emergency repair equipment.

[0044] like Figure 1 , Figure 7-10 As shown, the erection unit 1 includes a main beam 101, a first outrigger 102, a second outrigger 103, a third outrigger 104, a first four-axle bogie 105, a second four-axle bogie 106, a zero outrigger 107, two lifting trolleys 109, a lifting pier trolley 110, and a platform 111. Figure 2-6 As shown, the main beam 101 has a box-shaped cross-section and serves as the main load-bearing structure for the erection unit 1, providing a running track for the beam-lifting trolley 109 and the pier-lifting trolley 110. Figure 1-10 As shown, support leg 102, support leg 103, and support leg 104 are sequentially installed on the main beam 101 from front to back. Figure 1 , Figure 2 , Figure 7 As shown, in the transport state, the first four-axle bogie 105 is connected as a load-bearing wheel to the underside of the first outrigger 102. Figure 5 , Figure 8-10 As shown, when converted to the erection state, the first four-axle bogie 105 can be pulled backward to the second outrigger 103 by the wire rope generated by the winch installed in the second four-axle bogie 106, and is connected to the second outrigger 103 as a load-bearing wheel. Figure 4 , Figure 6-10 As shown, the second four-axle bogie 106, acting as a load-bearing wheel, is always connected to the underside of the third outrigger 104. The transport wheelbase during transport is 39.5m, ensuring that even on a 300m curve, the 105m cantilevered main beam 101 does not contact the tunnel surface when passing through a tunnel, thus meeting the transport requirements for small curves. In this embodiment, the second four-axle bogie 106 and the third outrigger 104 are connected by a pin joint.

[0045] Specifically, such as Figure 1 , Figure 2 , Figure 7 As shown, the first outrigger 102 and the first four-axle bogie 105 can be connected via a support beam 108. The support beam 108 is connected to the first four-axle bogie 105 via a pin and is positioned above the first four-axle bogie 105. The first outrigger 102 is a telescopic structure that passes through the main beam 101. In this embodiment, the first outrigger 102 consists of a vertical hydraulic cylinder and inner and outer sleeves. The lower end of the first outrigger 102 can be driven by the vertical hydraulic cylinder to extend downwards out of the main beam 101 and insert into the support beam 108, where it is detachably fixed.

[0046] In transit, such as Figure 1 , Figure 2 , Figure 7 As shown, the support beam 108 is connected to the first four-axle bogie 105 by a pin shaft. The vertical cylinder of the first outrigger 102 extends, so that the first outrigger 102 is inserted into the support beam 108 and connected to it by a pin shaft, so as to realize the connection between the first outrigger 102 and the first four-axle bogie 105.

[0047] In the setup state, such as Figure 8-10 As shown, the vertical cylinder of outrigger 102 shortens, causing outrigger 102 to retract into the main beam 101, creating space for the two lifting trolleys 109 and the gantry trolley 110 to move. Simultaneously, the gantry trolley 110 lifts the beam 108 from the first four-axle bogie 105 and places it in front of the first four-axle bogie 105. Then, as... Figure 5 , Figure 8-10 As shown, the first four-axle bogie 105 is pulled to the second outrigger 103 by the second four-axle bogie 106 to connect with it, so as to complete the change of wheel track.

[0048] like Figure 3 , Figure 5 As shown, the second support leg 103 includes four first rotatable multi-stage sleeves 1031, a first upper crossbeam 1032, a first lower crossbeam 1033, a second lower crossbeam 1034, and a first support leg 1035. The first rotatable multi-stage sleeves 1031 are C-shaped and their vertical parts are telescopic. Two first rotatable multi-stage sleeves 1031 form a pair. The upper ends of both pairs of first rotatable multi-stage sleeves 1031 are rotatably connected to the first upper crossbeam 1032 and are located on both sides of the first upper crossbeam 1032. The lower ends of both pairs of first rotatable multi-stage sleeves 1031 are rotatably connected to the first lower crossbeam 1033 and are located on both sides of the first lower crossbeam 1033. The second lower crossbeam 1034 is located below the first lower crossbeam 1033 and is movably connected to the first lower crossbeam 1033. The first support leg 1035 is fixed below the second lower crossbeam 1034.

[0049] The second outrigger 103 is sleeved on the outside of the main beam 101, so that the two pairs of first rotatable multi-stage sleeve columns 1031 are located on both sides of the main beam 101 respectively, and the upper cover plate 1011 of the main beam 101 is bolted to the first upper crossbeam 1032.

[0050] In the setup state, such as Figure 5 , Figure 8-10 As shown, the open ends of the two first rotatable multi-stage sleeve columns 1031 in each pair face the main beam 101. The vertical parts of the four first rotatable multi-stage sleeve columns 1031 extend out simultaneously, making room for the two lifting beam trolleys 109 and the lifting pier trolleys 110 to travel, and allowing the first support leg 1035 to be supported on the bridge surface. At this time, the first four-axle bogie 105 is set below the second support leg 103 and connected to the second support leg 103 through a pin engagement.

[0051] In transit, such as Figure 1 , Figure 3 , Figure 7 As shown, the openings of the two first rotatable multi-stage sleeves 1031 in each pair are arranged opposite each other, and the vertical parts of the four first rotatable multi-stage sleeves 1031 are retracted, so that the first support leg 1035 is away from the bridge surface.

[0052] In particular, Figure 3 , Figure 5 As shown, a transverse hydraulic cylinder 1036 is provided between the first lower crossbeam 1033 and the second lower crossbeam 1034. The transverse hydraulic cylinder 1036 can drive the first lower crossbeam 1033 and the second lower crossbeam 1034 to move laterally relative to each other, so that the main beam 101 can be driven by the second support leg 103 and rotate left and right about the third support leg 104 as the axis, thus realizing left and right swinging.

[0053] like Figure 4 , Figure 6As shown, the third support leg 104 includes four second rotatable multi-stage sleeves 1041, a second upper crossbeam 1042, a third lower crossbeam 1043, and a second support leg 1044. The second rotatable multi-stage sleeves 1041 are C-shaped and their vertical parts are telescopic. Two second rotatable multi-stage sleeves 1041 form a pair. The upper ends of the two pairs of second rotatable multi-stage sleeves 1041 are rotatably connected to the second upper crossbeam 1042 and are located on both sides of the second upper crossbeam 1042. The lower ends of the two pairs of second rotatable multi-stage sleeves 1041 are rotatably connected to the third lower crossbeam 1043 and are located on both sides of the third lower crossbeam 1043. The second support leg 1044 is fixed below the third lower crossbeam 1043.

[0054] The third outrigger 104 is sleeved on the outside of the main beam 101, so that the two pairs of second rotatable multi-stage sleeve columns 1041 are located on both sides of the main beam 101 respectively, and the upper cover plate 1011 of the main beam 101 is bolted to the second upper crossbeam 1042.

[0055] In the setup state, such as Figure 6 , Figure 8-10 As shown, the open ends of the two second rotatable multi-stage sleeve columns 1041 in each pair face the main beam 101. The vertical parts of the four second rotatable multi-stage sleeve columns 1041 extend out simultaneously, making room for the two lifting beam trolleys 109 and the lifting pier trolleys 110 to travel, and allowing the second support leg 1044 to be supported on the bridge surface.

[0056] In transit, such as Figure 1 , Figure 4 , Figure 7 As shown, the open ends of the two second rotatable multi-stage sleeves 1041 in each pair are arranged opposite each other, and the vertical parts of the four second rotatable multi-stage sleeves 1041 are contracted, so that the second support leg 1044 is away from the bridge surface.

[0057] When erected, the main beam 101 includes, as follows: Figure 8 The cantilever state of the pier erection process shown and as Figure 9 , Figure 10 The beam erection process is shown in a simply supported state. For example... Figure 7-10 As shown, the zero-type support leg 107 is a truss structure used to transform the main beam 101 into a simply supported state during the beam erection process. It includes a basic section 1071 and a movable section 1072. The basic section 1071 is hinged to the head end of the main beam 101, and the movable section 1072 is loaded onto the flatcar 21 along with the emergency repair equipment 3. The emergency repair equipment 3 includes multiple emergency repair piers 31 and multiple emergency repair beams 32. During pier erection, as... Figure 9 , Figure 10As shown, multiple emergency repair piers 31 are installed vertically in front of the bridge emergency repair section 4. After the emergency repair beam 32 is erected, the movable section 1072 is hoisted onto the top of the uppermost emergency repair pier 31 by the pier hoisting trolley 110. The movable section 1072 is a telescopic structure. In this embodiment, the movable section 1072 is a two-section sleeve structure that can be extended and retracted by a hydraulic cylinder, so that the upper and lower ends of the movable section 1072 can be bolted to the bottom end of the basic section 1071 and the top of the emergency repair pier 31, respectively, so as to transform the main beam 101 from the cantilever state during the pier erection process to the simply supported state during the beam erection process.

[0058] like Figure 2-6 As shown, racks 1013 are provided on the outer sides of the lower ear beams 1012 on both sides of the main beam 101, and the racks 1013 are arranged along the length of the lower ear beams 1012. Figure 1 , Figure 7-10 As shown, both gantry trolleys 109 are inverted and suspended from the lower ear beam 1012, and their gears mesh with the rack 1013 to allow them to travel along the main beam 101. Similarly, the pier trolley 110 is inverted and suspended from the lower ear beam 1012, and its own gears mesh with the rack 1013 to allow it to travel along the main beam 101. Both the gantry trolleys 109 and pier trolleys 110 are driven by two three-in-one geared motors, model R97-YVPJ 3-4P-1050.78-M1, which can be frequency-controlled between 0 and 10 m / min depending on the site conditions.

[0059] Two lifting trolleys 109 can be connected to both ends of the emergency repair beam 32 to lift the emergency repair beam 32. The pier lifting trolley 110 is used to lift the emergency repair pier 31, the support beam 108, and the movable section 1072.

[0060] like Figure 1 , Figure 7-10 As shown, platform 111 is fixed between outrigger 2 103 and outrigger 3 104. Platform 111 is used to receive emergency repair equipment 3 and movable section 1072 transported from transport unit 2.

[0061] like Figure 7-10 As shown, the transport unit 2 includes several flatcars 21 connected in sequence and two trolleys (not shown in the figure). The flatcars 21 are towed by a locomotive and are used to load the emergency repair equipment 3. The two trolleys are self-propelled and can run between the platform 111 and the flatcars 21 to transport the emergency repair equipment 3 and the movable section 1072 from the flatcars 21 to the platform 111. The movement of the two trolleys can be controlled synchronously, and can also be controlled synchronously with the lifting beam trolley 109. The erection unit 1 is connected to the flatcars 21 and the transport unit 2 through the coupler 1061 on the second four-axle bogie 106 to receive the emergency repair equipment 3 from the transport unit 2 and push it into the site via the existing bridge.

[0062] Both flatcar 21 and platform 111 are equipped with tracks for the transport trolleys. These tracks are equipped with a loading and securing system that meets the requirements of the Railway Administration's

[20105] No. 296 "Rules for Loading and Secured Railway Goods" and is used to secure the transport trolley tracks. During transport, the tracks are disconnected at the connection point of flatcar 21. After the car is stopped and braked, a short, overlapping rail is installed.

[0063] In this embodiment, the flatcar 21 is modified from the NX70 flatcar, and the number of flatcars 21 is determined by the number of emergency repair piers 31 required.

[0064] To ensure safe transportation and erection, a corresponding safety monitoring system was also developed. This system collects and transmits various information during the transportation and erection of emergency repair equipment for beam bridges. Data is remotely transmitted to an information management system, enabling remote monitoring and information-based management. According to national standards and design requirements, the monitoring content during equipment transportation and erection includes monitoring for winch overspeed, winch lifting height, wind speed, vehicle speed, equipment collision avoidance in tunnels, main beam and outrigger tilt, outrigger force, stress in key components, lifting point force, and video surveillance.

[0065] This invention also provides an emergency repair method for beam bridges, comprising the following steps:

[0066] S1: The support beam 108 is pin-connected to the first four-axle bogie 105. The vertical cylinder of the first outrigger 102 extends, allowing the first outrigger 102 to insert into the support beam 108 and connect with it via a pin, thus connecting the first outrigger 102 to the first four-axle bogie 105. The first four-axle bogie 105 then acts as a load-bearing wheel connected below the first outrigger 102. In each pair of the second outrigger 103, the openings of the two first rotatable multi-stage sleeves 1031 are arranged opposite each other, and the vertical portions of the four first rotatable multi-stage sleeves 1031 are retracted. The first support leg 1035 is moved away from the bridge surface. The open ends of the two second rotatable multi-stage sleeves 1041 in each pair of the third support leg 104 are set opposite each other. The vertical parts of the four second rotatable multi-stage sleeves 1041 are retracted, so that the second support leg 1044 is moved away from the bridge surface. The second four-axle bogie 106 is connected to the third support leg 104 as a load-bearing wheel. At this time, it is the transportation state of the beam bridge emergency repair equipment. At the same time, it is also the long-distance transportation state. The beam bridge emergency repair equipment stops when it reaches the bridge repair section 4.

[0067] S2: The second support leg 103 rotates so that the open ends of the two first rotatable multi-stage sleeve columns 1031 in each pair face the main beam 101, and the third support leg 104 rotates so that the open ends of the two second rotatable multi-stage sleeve columns 1041 in each pair face the main beam 101.

[0068] S3: The vertical cylinder of the No. 1 outrigger 102 shortens, causing the No. 1 outrigger 102 to retract into the main beam 101 and disengage from the first four-axle bogie 105. The trolley 110 lifts the support beam 108 from the first four-axle bogie 105 and removes it, placing it in front of the first four-axle bogie 105. The first four-axle bogie 105 is pulled to the No. 2 outrigger 103 by the second four-axle bogie 106, and the first four-axle bogie 105 is connected to the bottom of the No. 2 outrigger 103 as a load-bearing wheel. At this time, the emergency repair equipment for the beam bridge is in the short-distance erection state.

[0069] S4: The vertical parts of the four first rotatable multi-stage sleeve columns 1031 of the second outrigger 103 extend simultaneously to put them in the unfolded state, so that the first support leg 1035 is supported on the bridge surface. The vertical parts of the four second rotatable multi-stage sleeve columns 1041 of the third outrigger 104 extend simultaneously to put them in the unfolded state, so that the second support leg 1044 is supported on the bridge surface.
