Description

Technical Field

[0001] The invention relates to the technical field of high-speed railway box girder retaining wall construction, and in particular to a high-speed railway box girder retaining wall lifting and material distribution construction device and a construction method. Background Art

[0002] The three walls installed on the top of the high-speed railway box girder are important components of the box girder in the construction of high-speed railways, and play an important role in the safety of high-speed railway train operation. The three walls of the high-speed railway mainly include A wall, B wall (also called vertical wall) and protective wall (also called ballast retaining wall); At present, the three walls on the top of the high-speed railway box girder are mostly cast-in-place, that is, concrete is poured after steel formwork support, the formwork is removed and transferred, and then the support is installed. The number of steel formworks required and the number of turnovers of steel formworks are large, the on-site removal and transfer support time cycle is long, the number of manual installation and transportation of formworks is large, and the labor intensity is high; Before the construction of the three walls of the high-speed railway is completed, the box girders are placed in order on the construction site, and the steel formworks and construction equipment need to be circulated and transported between different box girders. The top surface of the box girder is at a high height from the ground, and the turnover transportation is very inconvenient. The equipment used in the three-wall construction includes concrete tank trucks (for providing concrete), handling equipment (for handling steel formwork on the top of the box beam or on the ground) and cranes (for moving the box beam up and down between handling equipment, steel formwork, etc., and pouring materials through the crane hopper). A pump truck can also be used in conjunction with a concrete tank truck for pouring, but the cost of using a pump truck is too high, and the pump truck is more suitable for pouring over a large area, which is not conducive to pouring in a narrow and long three-wall membrane cavity. The use of a pump truck for three-wall construction is not only costly but also relatively inefficient. The method of pouring materials by hanging a hopper with a crane takes a long time for the crane equipment, and when the crane hangs the hopper, the hopper end needs the cooperation of multiple people to accurately pour, which is inefficient and unsafe.

[0003] Therefore, how to provide a high-speed railway box girder retaining wall lifting material distribution construction device and construction method that can improve the construction efficiency of high-speed railway box girder retaining wall, reduce manual labor intensity and construction costs, and make equipment and mold turnover flexible and fast is a problem that technical personnel in this field urgently need to solve. Summary of the invention

[0004] In view of this, the present invention proposes a high-speed railway box girder retaining wall lifting and material distribution construction device and construction method, aiming to solve the technical problems of large and inflexible equipment and mold turnover workload, high manual labor intensity, low overall construction efficiency and high cost in the above-mentioned traditional high-speed railway box girder retaining wall construction.

[0005] In order to achieve the above object, the present invention adopts the following technical solution: One aspect of the present invention provides a high-speed railway box girder retaining wall lifting and laying material construction device, comprising: A lifting platform vehicle, the lifting platform vehicle comprising a traveling chassis and a lifting platform mechanism mounted on the traveling chassis, the lifting platform mechanism being arranged and connected to one side of a box beam to construct a construction lifting and conveying passage for the upper and lower box beams, so as to convey construction materials and construction equipment between the ground and the top surface of the box beam; A concrete placing and pouring vehicle, which can move the box beam up and down through the lifting platform mechanism to transfer the concrete for pouring, and can pour concrete into the pouring cavity of the box beam retaining wall; The handling equipment is used to carry construction materials, and the handling equipment can move the box beam up and down through the lifting platform mechanism.

[0006] When the high-speed railway box girder retaining wall lifting material distribution construction device of the present invention is used, the lifting platform mechanism is driven to move forward by the walking chassis, and the lifting platform mechanism can be conveniently arranged and connected to one side of the box girder to construct a construction lifting and conveying channel for construction materials and construction equipment to go up and down the box girder; construction personnel can also go up and down the box girder through the lifting platform mechanism, and the safety of construction personnel going up and down the box girder is reliably guaranteed; the material distribution pouring vehicle can be used for concrete pouring operations, and can also travel between the ground and the top surface of the box girder through the lifting platform mechanism to transport concrete for pouring, without the need for a pump truck to load materials, thus saving the cost of concrete loading. The handling equipment is used to carry construction materials such as construction steel formworks for constructing the retaining wall casting cavity; the material distribution pouring vehicle, handling equipment, and necessary materials for construction such as formworks, construction tools, and supplies for retaining wall construction can all go up and down the box girder through the lifting platform mechanism, without the need for crane assistance, thus improving the flexibility of construction, improving construction efficiency, and reducing construction costs. The present invention constructs a construction lifting and conveying channel for the upper and lower box girders through a lifting platform vehicle, which eliminates the need for expensive cranes and pump trucks to assist in material laying. The construction lifting and conveying channel improves the flexibility of construction materials and equipment for the upper and lower box girders and the speed of construction, reduces the turnover workload of construction materials such as formwork, greatly reduces manual labor intensity and construction costs, and significantly improves the overall construction efficiency.

[0007] As a further improvement, the material placing and pouring vehicle comprises a traveling vehicle body and a pouring mechanism mounted on the traveling vehicle body for pouring retaining walls; the pouring mechanism is detachably fixedly mounted on a vehicle plate of the traveling vehicle body; the handling equipment can move the pouring mechanism away from the vehicle plate, so that the vehicle plate becomes a loading plate for construction templates.

[0008] The beneficial effect of the above technical solution is that the pouring mechanism is equipped with a walking vehicle body, which can be conveniently walked along the length direction of the high-speed railway box beam retaining wall for continuous pouring operations. The conventional construction method is to use handling equipment to transport the construction template. After the pouring mechanism is separated from the walking vehicle body, the vehicle plate of the walking vehicle body can be used to assist in transporting the construction template. One vehicle has two uses. In conjunction with the handling equipment, the turnover efficiency of the construction template can be significantly improved, and the labor intensity and construction cost can be greatly reduced.

[0009] Further improvement, the casting mechanism includes a frame, a hopper and a discharge pipe mechanism; the frame is detachably connected to the top of the vehicle plate; the hopper is fixedly mounted on the frame, and has an inlet at the top and a discharge port at the bottom; the discharge pipe mechanism is mounted on the frame or the hopper; the inlet of the discharge pipe mechanism is connected to the discharge port, and the discharge port is used to pour concrete into the casting cavity of the box girder retaining wall.

[0010] The beneficial effects of the above technical solution are: the frame is used to support the fixed hopper, the inlet at the top of the hopper is used to load concrete, and the discharge port at the bottom is used to discharge concrete; the discharge pipe mechanism is used to transport the concrete discharged from the discharge port to the box beam retaining wall casting cavity for pouring.

[0011] As a further improvement, the discharge pipe mechanism includes a tubular screw conveyor and a swing drive mechanism; The tubular screw conveyor is rotatably mounted on the frame or the hopper, and has a feed port at one end and a discharge port at the other end; the feed port is connected to the discharge port; the swing drive mechanism is mounted on the frame or the hopper, and its driving end is transmission-connected to the tubular screw conveyor to drive its swing, and can move the discharge port to the side of the frame and above the corresponding box beam retaining wall casting cavity to be in a casting operation state, and can move the discharge port close to the frame or to the inside of the frame to be in a retracted state.

[0012] The beneficial effects of the above technical solution are: the tubular screw conveyor is used to transport concrete discharged from the discharge port to the box girder retaining wall casting cavity; the tubular screw conveyor is rotatably installed on the frame or the hopper, and the tubular screw conveyor can be driven and controlled by the swing drive mechanism to swing out to the side of the frame, so that its discharge port corresponds to the top of the box girder retaining wall casting cavity for casting operations; after casting is completed, the tubular screw conveyor can be swung back to the frame or recovered to the inside of the frame without affecting the movement of the material placing and casting vehicle.

[0013] As a further improvement, there are three groups of discharge pipe mechanisms; the feed ports of the three groups of discharge pipe mechanisms are all connected to the discharge port, and the discharge ports can discharge materials from the casting cavities of the A wall, the B wall and the protective wall of the high-speed railway box girder retaining wall corresponding to the side of the traveling vehicle body.

[0014] The beneficial effect of the above technical solution is: three groups of discharge pipe mechanisms are set up to correspond to the casting cavities of the A wall, B wall and protective wall of the high-speed railway box girder retaining wall for discharge and casting, thereby improving the casting operation efficiency.

[0015] Further improvement, the pouring mechanism also includes a lifting leg; the frame includes a bottom plate and a support column; the bottom plate is arranged parallel to the top of the vehicle plate; the bottom end of the support column is fixed to the upper end of the bottom plate, the hopper is arranged above the bottom plate and fixed to the top end of the support column; the discharge port can correspond to the side of the walking vehicle body; The fixed end of the lifting leg one is fixed to the upper end of the base plate, and the telescopic end of the lifting leg one can move downward to pass through the base plate surface and can be detachably connected to the vehicle plate, so as to drive the frame to rise and fall relative to the vehicle plate, thereby raising and lowering the feed port and the discharge port.

[0016] The beneficial effects of the above technical solution are: the telescopic end of the lifting leg one abuts against the vehicle plate surface of the walking vehicle body, and when it is extended and retracted, it can drive the frame to rise and fall, and drive the hopper and the discharge port to rise and fall in height; therefore, when loading concrete, it can ensure that it can be connected with the slurry outlet of the concrete supply equipment; when pouring, the discharge port can be lifted and connected above the pouring cavity of the box beam retaining wall.

[0017] Further improvement, the lifting platform mechanism includes a frame body, a lifting platform, a lifting drive mechanism and two lifting legs; the frame body is detachably connected to the top of the walking chassis; the fixed end of the two lifting legs is fixedly installed on the bottom of the frame body, and the telescopic end thereof can be extended downward to abut against the ground and lift the frame body, so that the frame body and the walking chassis are separated up and down; the telescopic end of the two lifting legs can be retracted upward to place the frame body on the ground, or to support the frame body on the ground.

[0018] The lifting platform is arranged horizontally and is slidably connected to the frame body along the height direction of the frame body; the lifting drive mechanism is installed on the frame body, and its driving end is transmission-connected to the lifting platform, which can drive the lifting platform to rise to correspond to and connect with the top surface of the box beam, and to descend to approach and connect with the ground.

[0019] The beneficial effects of the above technical solution are: the lifting drive mechanism is used to drive the lifting platform to lift and lower. The lifting platform can connect to the top surface of the box beam when it rises, and can connect to the ground when it descends, so that the lifting platform becomes a conveying platform built between the ground and the top surface of the box beam, which is used to convey construction equipment and construction materials; the lifting leg two serves as the telescopic leg of the frame body, which can separate the frame body from the walking chassis. After the frame body is separated from the walking chassis, the walking chassis can be moved away from under the frame body; when the ground is flat, the telescopic end of the lifting leg two can be retracted upward so that the frame body can be placed directly on the ground; when the ground is uneven, the frame body can be supported on the ground by the lifting leg two (if necessary, a support pad can be placed at the bottom of the frame body) to maintain its own upright state to ensure the stability of the lifting operation.

[0020] According to a further improvement, the lifting platform is located inside the frame body; a passage opening 1 for raising and lowering the lifting platform is provided on the lower side of the frame body; a passage opening 2 for raising and lowering the box girder is provided on the side of the frame body, which can correspond to the top surface of the box girder; a passage opening 3 is provided on the side of the frame body opposite to the passage opening 2, corresponding to the passage opening 2; when the height of the lifting platform corresponds to the height of the top surface of the box girder, the passage opening 2, the space above the lifting platform and the passage opening 3 jointly construct a lintel passage that can be built between the opposite ends of two adjacent box girders.

[0021] The beneficial effects of the above technical solution are: when in use, the lifting platform descends to the lower part of the frame body and corresponds to the channel opening 1, the construction equipment or construction materials enter from the channel opening 1 to the upper end of the lifting platform, the lifting platform carries the construction equipment or construction materials and rises to the corresponding box beam top surface, and the construction equipment or construction materials are transferred from the channel opening 2 to the box beam top surface. In addition, the arrangement of the box beams in the box beam site is orderly, the two adjacent groups of box beams are placed relative to each other along the length direction, each group of box beams are placed side by side along the width direction, and the adjacent two groups of box beams are designed as a channel; when the lifting platform vehicle of the present invention is used, it is moved and arranged in the channel between the two adjacent groups of box beams, and close to the end of the docking box beam, wherein the channel opening 2 docks one end of the length direction of a box beam, and the channel opening 3 docks one end of the length direction of the other opposite box beam, so as to build a beam channel above the channel between the two adjacent box beams, and the construction equipment and construction materials can be directly transferred from the top surface of one box beam to the top surface of another box beam through the beam channel, which greatly improves the construction efficiency and reduces the labor intensity and construction cost.

[0022] As a further improvement, there are multiple lifting platform mechanisms, and the multiple lifting platform mechanisms are arranged between two adjacent box girders and arranged in sequence along the relative directions of the two adjacent box girders; the beam passages of the multiple lifting platform mechanisms are connected in sequence to construct a beam bridge road between the two adjacent box girders.

[0023] The beneficial effect of the above technical solution is that when the passage between two adjacent box girders is wide, a beam bridge road can be constructed by connecting the beam passages of multiple lifting platform mechanisms in sequence, thereby realizing the rapid transfer of construction equipment and materials between two adjacent box girders.

[0024] Another aspect of the present invention provides a method for lifting and distributing materials for a high-speed railway box girder retaining wall, including the above-mentioned device for lifting and distributing materials for a high-speed railway box girder retaining wall, and the specific construction steps are: Step 1: Arrange and connect the lifting platform mechanism of the lifting platform vehicle to one side of the box beam; connect the material placing vehicle to the concrete supply equipment for loading; Step 2: Use the lifting platform mechanism to transport the concrete placing truck, handling equipment and construction materials from the ground to the top surface of the box beam; Step 3: Install the retaining wall formwork and construct the box beam retaining wall casting cavity; Step 4: Use a concrete placing vehicle to pour concrete into the casting cavity of the box girder retaining wall.

[0025] The beneficial effects of the above technical scheme are: using the lifting platform mechanism to build a construction lifting and conveying channel for the upper and lower box girders on one side of the box girder, and using a concrete placing truck that can be loaded with concrete to transfer concrete for pouring and to cast retaining walls, which changes the traditional high-speed railway box girder retaining wall construction method that must use cranes and pump trucks. The turnover of construction materials and construction equipment is faster, the construction safety is better, the construction efficiency can be greatly improved, and the construction cost can be reduced.

[0026] As a further improvement of the above technical solution, it also includes step five: arranging at least one of the lifting platform mechanisms between two adjacent box girders along the relative directions of the two adjacent box girders, and building a beam bridge road connecting the two adjacent box girders by connecting the beam channels of at least one lifting platform mechanism in sequence; the material placing and pouring vehicle, handling equipment and construction materials are transferred or transported through the beam bridge road.

[0027] The beneficial effect of the above technical solution is that the number of lifting platform mechanisms can be flexibly arranged according to the width of the channel between two adjacent box girders, so that a bridge connecting the two adjacent box girders can be quickly built at the channel between the two adjacent box girders, so that after the construction of one box girder retaining wall is completed, the construction equipment and construction materials can be quickly transferred and transported to the top surface of another adjacent box girder, which can significantly improve construction efficiency and reduce construction costs.

[0028] It can be seen from the above technical solutions that, compared with the prior art, the present invention discloses a high-speed railway box girder retaining wall lifting material distribution construction device and construction method, which has the following advantages and beneficial effects: 1. The present invention uses a lifting platform vehicle to construct a construction lifting and conveying channel for the upper and lower box beams, which greatly improves the flexibility of construction personnel, materials and equipment in moving the upper and lower box beams and the speed of construction, reduces the turnover workload of construction materials such as templates, greatly reduces manual labor intensity and construction costs, and significantly improves the overall construction efficiency; 2. The material placing and pouring vehicle of the present invention has multiple functions such as transporting concrete, pouring concrete and transporting construction templates, which improves the utilization rate of the equipment and reduces the construction cost; 3. The present invention builds a bridge between adjacent box girders through a lifting platform mechanism. Construction materials, equipment and personnel do not need to repeatedly go up and down the box girders, and can be quickly circulated directly through the bridge, thereby improving construction efficiency and further reducing construction costs.

The handling equipment 3 can move up and down the box beam 4 via the lifting platform mechanism 12 .

[0037] When the high-speed railway box girder retaining wall lifting material distribution construction device of the present invention is used, the lifting platform mechanism 12 is driven to move forward by the walking chassis 11, and the lifting platform mechanism 12 can be conveniently arranged and connected to one side of the box girder 4 to construct a construction lifting and conveying channel for construction materials and construction equipment to go up and down the box girder; construction personnel can also go up and down the box girder through the lifting platform mechanism 12, and the safety of construction personnel going up and down the box girder is reliably guaranteed; the material distribution pouring vehicle 2 can be used for concrete pouring operations, and can also be driven between the ground and the top surface of the box girder through the lifting platform mechanism 12 to transport the pouring concrete, without the need for a pump truck to load the material, thus saving the cost of concrete loading.

The present invention constructs a construction lifting and conveying channel for the upper and lower box beams through a lifting platform vehicle 1, which eliminates the need for expensive cranes and pump trucks to assist in material laying. The construction lifting and conveying channel improves the flexibility of construction materials and equipment for the upper and lower box beams and the speed of construction, reduces the turnover workload of construction materials such as formwork, greatly reduces manual labor intensity and construction costs, and significantly improves the overall construction efficiency.

After the casting mechanism 22 is detached from the walking body 21 of the present invention, the vehicle plate 211 of the walking body 21 can be used to assist in transporting the construction template. One vehicle has two uses. In conjunction with the handling equipment 3, the turnover efficiency of the construction template can be significantly improved, and the labor intensity and construction cost can be greatly reduced.

[0044] Embodiment 2 differs from Embodiment 1 in that the traveling vehicle body 21 uses a self-powered, self-propelled wheeled or tracked chassis. When the traveling chassis 11 uses an unpowered chassis, the traveling chassis 11 can be driven by the traveling vehicle body 21 to further improve the utilization efficiency of the construction equipment and reduce the equipment cost.

[0045] In some embodiments, Figure 5 and Figure 6 As shown, the casting mechanism 22 includes a frame 221, a hopper 222 and a discharge pipe mechanism 223; the frame 221 is detachably connected to the top of the vehicle plate 211; the hopper 222 is fixedly installed on the frame 221, and a feed port 2221 is provided on the top and a discharge port 2222 is provided on the bottom; the discharge pipe mechanism 223 is installed on the frame 221 or the hopper 222; the feed port 2231A of the discharge pipe mechanism 223 is connected to the discharge port 2222, and the discharge port 2231B is used to pour concrete into the box beam retaining wall casting cavity 6.

[0050] In some embodiments, the tubular screw conveyor 2231 can use existing products; the conveying direction of the tubular screw conveyor 2231 can be designed to be horizontal or inclined downward to reduce the resistance of concrete transportation and reduce energy consumption; arranging the tubular screw conveyor 2231 horizontally or inclined downward can facilitate cleaning of the pipeline and avoid concrete adhesion and blockage.

[0051] In some embodiments, the conveying tube of the tubular screw conveyor 2231 includes a tube body and a top cover; the tube wall of the tube body is open along the length direction, and the top cover is removably sealed with screws; when it is necessary to clean the inner wall of the tube body and the internal spiral blades, the top cover can be opened and a cleaning tool can be used to clean deep into the tube from the opening.

[0052] Embodiment 4 is different from Embodiment 3 in that Figure 6 and Fig. 9 As shown, there are three groups of discharge pipe mechanisms 223; three discharge ports 2222 are arranged at intervals at the bottom of the hopper 222; the feed ports 2231A of the three groups of discharge pipe mechanisms 223 are connected to the three discharge ports 2222 in a one-to-one correspondence, and the discharge ports 2231B thereof can discharge materials in a one-to-one correspondence with the casting cavities of the A wall, the B wall and the protective wall of the high-speed railway box girder retaining wall on the side of the walking body 21.

[0053] Three groups of discharge pipe mechanisms 223 are arranged to discharge and pour material corresponding to the A wall, B wall and protective wall of the high-speed railway box girder retaining wall, thereby improving the efficiency of the pouring operation.

[0054] Embodiment 5 is different from Embodiment 4 in that Figure 8 and Fig. 9 As shown, the pouring mechanism 22 further includes a lifting leg 224; the frame 221 includes a bottom plate 2211 and a support column 2212; the bottom plate 2211 is arranged parallel to the top of the vehicle plate 211; the bottom end of the support column 2212 is fixed to the top of the bottom plate 2211, and the hopper 222 is arranged above the bottom plate 2211 and fixed to the top of the support column 2212; the discharge port 2231B can correspond to the side of the walking vehicle body 21; The fixed end of the lifting leg 224 is fixed to the upper end of the bottom plate 2211, and the telescopic end of the lifting leg 224 can move downward to penetrate the bottom plate 2211 and can be detachably connected to the vehicle plate 211, which can drive the frame 221 to rise and fall relative to the vehicle plate 211, thereby raising and lowering the feed port 2221 and the discharge port 2231B.

[0055] The telescopic end of the lifting leg 224 abuts against the surface of the vehicle plate 211. When it is extended or retracted, it can drive the frame 221 to rise and fall, and drive the hopper 222 and the discharge port 2231B to rise and fall in height; therefore, when loading concrete, it can ensure that the feed port 2221 can be connected with the slurry outlet of the concrete supply equipment 5; during pouring, the discharge port 2231B can be lifted and connected above the box beam retaining wall pouring cavity 6.

[0056] Specifically, there are multiple lifting legs 224, and the multiple lifting legs 224 are distributed circumferentially along the bottom plate 2211.

[0057] In this embodiment, there are four lifting legs 224.

As the traveling body 21 moves along the length direction of the box girder retaining wall, the grouting of the pouring cavities of the A wall, B wall and protective wall is realized. Since the amounts of concrete required for the pouring cavities of the A wall, B wall and protective wall are different, the quantitative and uniform pouring of concrete can be achieved by adjusting the traveling speed of the traveling body 21 and controlling the discharge speed and discharge amount of the three groups of discharge pipe mechanisms 223.

[0059] Specifically, the three discharge ports 2222 of the hopper 222 are arranged at intervals along the length direction of the traveling vehicle body 21 , and are also arranged at intervals along the width direction of the traveling vehicle body 21 .

[0060] Furthermore, the swing drive mechanism 2232 is composed of three groups, each including a rotating base 2232A and a driving motor 2232B; the three rotating bases 2232A are arranged one by one below the three discharge ports 2222 and their fixed ends are fixedly mounted on the base plate 2211; the casing of the driving motor 2232B is fixed on the base plate 2211, and the rotating shafts of the three driving motors 2232B are transmission-connected to the rotating ends of the three rotating bases 2232A one by one, and can drive the rotating ends of the corresponding rotating bases 2232A to rotate around the central axis of the vertical base 2211; the pipe bodies of the three groups of discharge pipe mechanisms 223 are fixed one by one on the rotating ends of the three rotating bases 2232A; the pipe bodies and tube walls of the three groups of discharge pipe mechanisms 223 are connected to the three discharge ports 2222 one by one through the connecting pipe assembly 2233. The driving motor 2232B drives the rotating end of the rotating base 2232A to rotate, which in turn drives the tube body of the corresponding discharge tube mechanism 223 to swing. The tube body of the discharge tube mechanism 223 can swing out to the side of the walking body 21, and can also swing back to the top of the corresponding bottom plate 2211.

[0061] In some embodiments, the rotating base 2232A includes a fixed base and a rotating support cylinder rotatably connected to the fixed base. The rotating support cylinder can be rotatably connected to the fixed base through a bearing. The rotating support cylinder is the rotating end.

[0064] Furthermore, the connecting pipe assembly 2233 includes a pipe 1 fixed and connected to the discharge port 2222, a pipe 2 fixed and connected to the pipe body of the discharge pipe mechanism 223, and a pump pipe clamp; the pipe 1 and the pipe 2 are rotatably connected and connected through the pump pipe clamp. When the pipe body of the discharge pipe mechanism 223 swings, the pipe 1 and the pipe 2 rotate relative to each other.

[0065] Specifically, a support rod 2234 is connected between the conveying pipe of the tubular screw conveyor 2231 and the rotating end of the rotating base 2232A. The support rod 2234 supports the conveying pipe of the tubular screw conveyor 2231 and prevents the longer conveying pipe from bending and deforming.

[0066] Specifically, there are multiple support columns 2212, and the specific number and position can be arranged as needed; in order to avoid the support columns interfering with the conveying pipe of the tubular screw conveyor 2231 in the retracted state, a detachable support column 2213 is installed at the bottom end of the hopper 222 corresponding to the discharge port 2231B of the tubular screw conveyor 2231.

[0069] The lifting drive mechanism 123 is used to drive the lifting platform 122 to rise and fall. The lifting platform 122 can connect to the top surface of the box beam 4 when it rises, and can connect to the ground when it descends, so that the lifting platform 122 becomes a conveying platform built between the ground and the top surface of the box beam 4, which is used to convey construction equipment and construction materials.

[0071] When in use, the lifting platform 122 descends to the lower part of the frame body 121 and corresponds to the passage opening 1211. The construction equipment or construction materials enter from the passage opening 1211 to the upper end of the lifting platform 122. The lifting platform 122 carries the construction equipment or construction materials up to the corresponding top surface of the box beam 4. The construction equipment or construction materials are transferred from the passage opening 2 1212 to the top surface of the box beam 4.

[0072] Specifically, the frame body 121 is in the shape of a cuboid, including four columns 1215 arranged in a rectangular array, a bottom beam 1216 fixedly connected to the bottom of the four columns, a top beam 1217 fixedly connected to the top of the four columns, and a middle beam 1218 fixedly connected to the middle of the four columns; the columns 1215, the bottom beam 1216, the top beam 1217 and the middle beam 1218 together form a cubic frame, and the interior of the frame body 121 is a lifting passage; the lifting platform 122 is horizontally located inside the frame body 121, and slide grooves 1215A are provided on the four columns 1215 in the height direction, and sliders 1221 adapted to the slide grooves are fixed at the corresponding slide grooves on the periphery of the lifting platform 122.

[0073] Specifically, the lifting drive mechanism 123 is composed of four groups, each including a hydraulic cylinder 1231, a transmission wheel 1232 and a transmission chain 1233; the four hydraulic cylinders 1231 are fixed in parallel on the four columns 1215 one by one, and their lower ends are fixed ends and are all abutted against the upper end of the mounting plate 1219, and their upper ends are telescopic ends; the telescopic ends of the four hydraulic cylinders 1231 are rotatably mounted with transmission wheels 1232; the transmission wheel 1232 is slidably connected to the column 1215 through a sliding bracket 1235, and the sliding bracket 1235 is slidably connected to the column 1215 along the height direction of the column 1215; one ends of the four transmission chains 1233 are fixed on the outer peripheral walls of the four columns 1215 one by one, and the other ends of the four transmission chains 1233 are bypassed around the four transmission wheels 1232 one by one and are fixedly connected to the corresponding sliders 1221. During operation, the telescopic end of the hydraulic cylinder 1231 drives the transmission wheel 1232 to rise and fall, and the transmission wheel 1232 drives the other end of the corresponding transmission chain 1233 to rise and fall, thereby driving the corresponding slider 1221 to rise and fall, and the four sliders 1221 rise and fall synchronously to drive the lifting platform 122 to rise and fall.

[0074] Specifically, the transmission wheel 1232 can be a sprocket, and the transmission chain 1233 is a chain adapted to the sprocket; the transmission wheel 1232 can also be a pulley, and the transmission chain 1233 is a steel wire rope adapted to the pulley. Two opposite transmission wheels 1232 are connected by a connecting shaft 1234.

[0075] In addition, in some embodiments, a channel opening three 1213 is provided at the side of the frame body 121 opposite to the channel opening two 1212 corresponding to the channel opening two 1212; when the height of the lifting platform 122 corresponds to the height of the top surface of the box beam 4, the channel opening two 1212, the space above the lifting platform 122 and the channel opening three 1213 jointly construct a lintel channel 1214 that can be built between the opposite ends of two adjacent box beams 4.

[0076] Embodiment 8 is different from Embodiment 7 in that Figure 4 As shown, the frame body 121 is detachably connected to the top of the walking chassis 11; the bottom of the frame body 121 is provided with a lifting leg 2 124. The fixed end of the lifting leg 2 124 is fixedly installed at the bottom of the frame body 121, and its telescopic end can be extended downward to abut against the ground and lift the frame body 121, so that the frame body 121 and the walking chassis 11 are separated from each other; the telescopic end of the lifting leg 2 124 can be retracted upward to place the frame body 121 on the ground, or to support the frame body 121 on the ground.

[0077] The lifting leg 2 124 serves as the telescopic leg of the frame body 121, and can separate the frame body 121 from the walking chassis 11. After the frame body 121 is separated from the walking chassis 11, the walking chassis 11 can be moved away from under the frame body 121; when the ground is flat, the telescopic end of the lifting leg 2 124 can be retracted upward so that the frame body 121 can be placed directly on the ground; when the ground is uneven, the frame body 121 can be supported on the ground by the lifting leg 2 124, and if necessary, a supporting pad can be placed at the bottom of the frame body to maintain its own upright state to ensure the stability of the lifting operation.

[0078] The frame body 121 also includes a mounting plate 1219, which is fixed to the bottom ends of the columns 1215 and the bottom cross beam 1216; the mounting plate 1219 is detachably connected to the top of the walking chassis 11 by bolts; the fixed end of the second lifting leg 124 is fixedly mounted on the upper end of the mounting plate 1219, and its telescopic end can move downward through the mounting plate 1219 and extend to the bottom thereof to abut against the ground and lift the frame body 121, so that the mounting plate 1219 of the frame body 121 is separated from the walking chassis 11 up and down; the telescopic end of the second lifting leg 124 can be retracted upward to place the mounting plate 1219 of the frame body 121 on the ground, or to support the frame body 121 on the ground.

[0079] Specifically, the lifting legs 124 are divided into two groups, each group of lifting legs 124 includes a plurality of lifting legs 124; the two groups of lifting legs 124 are symmetrically arranged on both sides of the width direction of the mounting plate 1219; and each group of lifting legs 124 is arranged at intervals along the length direction of the mounting plate 1219. The vertical state of the frame body 121 can be adjusted by adjusting the extension amount of the lifting legs 124.

[0080] Specifically, the mounting plate 1219 is rectangular, and there are four lifting legs 124 , which are respectively mounted at four corner ends of the mounting plate 1219 .

[0081] Specifically, a top cover may be installed on the top of the frame body 121 to prevent rain and sun, and a protective net or guardrail may be installed on the surrounding side.

[0082] Embodiment 9 is different from Embodiment 8 in that Figure 4 As shown, a flip connecting plate 1211A is hingedly connected to the bottom of the corresponding channel opening 1211 on the frame body 121; a flip connecting plate 2 1212A is hingedly connected to the bottom of the corresponding channel opening 2 1212 on the frame body 121; and a flip connecting plate 3 1213A is hingedly connected to the bottom of the corresponding channel opening 3 1213 on the frame body 121.

[0083] Specifically, one end of the flip connecting plate 1211A is hinged on the frame body 121, and the other end can be flipped to abut the ground to form an inclined ramp connecting the ground and the lifting platform 122; one end of the flip connecting plate 1212A is hinged on the frame body 121, and the other end can be flipped and erected on the top surface of the box girder to form a connecting aisle plate between the top surface of the box girder and the lifting platform 122; one end of the flip connecting plate 1213A is hinged on the frame body 121, and the other end can be flipped and erected on the top surface of the box girder to form a connecting aisle plate between the top surface of the box girder and the lifting platform 122.

[0084] Specifically, when the flip link plate 2 1212A and the flip link plate 3 1213A are flipped to a horizontal state, the bottom ends of the flip link plate 2 1212A and the flip link plate 3 1213A are adapted to press against the top surface of the middle cross beam 1218; the middle cross beam 1218 serves to support the corresponding flip link plate 2 1212A and the flip link plate 3 1213A.

[0085] The arrangement of the box girders in the box girder site is orderly, with two adjacent groups of box girders placed opposite to each other in the length direction, each group of box girders placed side by side in the width direction, and a passage designed between two adjacent groups of box girders; when the lifting platform vehicle 1 of the present invention is used, it is moved and arranged in the passage between two adjacent groups of box girders, and close to the end of the docking box girder, wherein the second passage opening 1212 docks one end of a box girder in the length direction, and the third passage opening 1213 docks one end of the other opposite box girder in the length direction, so as to build a lintel passage 1214 above the passage between the two adjacent box girders, and construction equipment and construction materials can be directly transferred from the top surface of one box girder through the lintel passage 1214 to the top surface of another box girder, which greatly improves the construction efficiency and reduces the labor intensity and construction cost.

[0086] In some embodiments, there are multiple lifting platform mechanisms 12, and the multiple lifting platform mechanisms 12 are arranged between two adjacent box girders 4 and arranged in sequence along the relative directions of the two adjacent box girders 4; the beam channels 1214 of the multiple lifting platform mechanisms 12 are connected in sequence to construct a beam bridge between two adjacent box girders 4.

[0087] Embodiment 10 is different from Embodiment 9 in that Figure 2 and Figure 3 As shown, when the passage between two adjacent box girders is wide, a beam bridge road can be constructed by connecting the beam passages 1214 of multiple lifting platform mechanisms 12 in sequence, thereby realizing the rapid transfer of construction equipment and materials between two adjacent box girders.

[0088] Specifically, two adjacent lifting platform mechanisms 12 are connected by the flip connecting plate 2 1212A and the flip connecting plate 3 1213A to form a connecting aisle plate between the beam channels 1214, so as to achieve seamless connection of the beam bridge road and ensure smooth passage of equipment and materials.

[0089] Another embodiment provides a method for lifting and distributing materials for a high-speed railway box girder retaining wall, including a device for lifting and distributing materials for a high-speed railway box girder retaining wall, and the specific construction steps are as follows: Step 1: Arrange and connect the lifting platform mechanism 12 of the lifting platform vehicle 1 to one side of the box beam 4; connect the material placing and pouring vehicle 2 to the concrete supply device 5 for loading; Step 2: Use the lifting platform mechanism 12 to transport the concrete placing vehicle 2, the handling equipment 3 and the construction materials from the ground to the top surface of the box beam 4; Step 3: Install the retaining wall formwork to construct the box beam retaining wall casting cavity 6; Step 4: Use the material placing and pouring vehicle 2 to pour concrete into the box beam retaining wall pouring cavity 6.

[0090] A lifting platform mechanism 12 is used to build a construction lifting and conveying channel for the upper and lower box beams on one side of the box beam 4, and a concrete placing vehicle 2 that can be loaded with concrete is used to transfer concrete for pouring and to cast retaining walls. This changes the traditional construction method of high-speed railway box beam retaining wall construction that must use cranes and pump trucks. The turnover of construction materials and construction equipment is faster, the construction safety is better, the construction efficiency can be greatly improved, and the construction cost can be reduced.

[0091] Specifically, in step one, the specific arrangement process of the lifting platform mechanism 12 is as follows: the walking chassis 11 of the lifting platform vehicle 1 can use a power chassis to move by itself to move the lifting platform mechanism 12 to one side of the length direction of the box beam 4, or it can be dragged by other power walking equipment; in order to save equipment and construction costs, the walking chassis 11 can be designed as an unpowered chassis, and the walking chassis 11 of the lifting platform vehicle 1 can be dragged by the walking body 21 of the material pouring vehicle 2 for walking; after moving the lifting platform mechanism 12 to one side of the length direction of the box beam 4, the walking chassis 11 is removed, and the frame body 121 is placed on the ground; open the flip connecting plate 1 1211A to construct an inclined ramp for the upper and lower lifting platforms 122; open the flip connecting plate 2 1212A to overlap the top surface of the box beam 4, and the lifting platform mechanism 12 is arranged.

[0092] Specifically, in step 2, construction workers can also move up and down the box beam 4 through the lifting platform mechanism 12; when the construction steel formwork is transported, the casting mechanism 22 is moved away from the vehicle plate 211 through the handling equipment 3; the steel formwork is transported by the handling equipment 3 or loaded on the vehicle plate 211 of the material-casting vehicle 2, and the construction steel formwork is transported to the top surface of the box beam 4 through the walking body 21 of the material-casting vehicle 2, making full use of the functions of the construction equipment and reducing construction costs. When the construction casting concrete is transported, the casting mechanism 22 is placed on the vehicle plate 211 through the handling equipment 3, and the walking body 21 drags the casting mechanism 22 to the concrete supply equipment 5, and the height of the feed port 2221 of the hopper 222 is adjusted by the lifting leg 1 224, so that the slurry outlet of the concrete supply equipment 5 and the feed port 2221 of the hopper 222 are connected up and down, and concrete is loaded.

[0093] Specifically, during construction, the concrete supply equipment 5 can be a concrete tank truck or a concrete mixing supply station; if there is a concrete mixing station at or near the construction site, the concrete placing and pouring vehicle 2 can be directly driven and operated to the concrete mixing station to load the materials.

[0094] Specifically, after the construction is completed, the lifting platform mechanism 12 is used to transport the material placing vehicle 2, the handling equipment 3 and the construction materials from the top surface of the box beam 4 to the ground.

[0095] Specifically, in step three: the installation of retaining wall formwork and the binding and installation of steel bars can refer to the existing technology.

[0096] Specifically, in step four, the walking vehicle 21 moves close to the box beam retaining wall casting cavity 6, and the discharge pipe mechanism 223 is raised and lowered by telescopically adjusting the lifting leg 224 so that its height is higher than the top of the box beam retaining wall casting cavity 6, and the discharge port 2231B corresponds to the top of the box beam retaining wall casting cavity 6.

[0097] Specifically, the tubular screw conveyor 2231 is driven to swing by the swing drive mechanism 2232 to adjust the position of the discharge port 2231B, and the discharge port 2231B is always kept corresponding to the top of the box beam retaining wall casting cavity 6, so that the concrete flowing out of the discharge port 2231B naturally falls into the box beam retaining wall casting cavity 6. The walking vehicle 21 is controlled to travel along the length direction of the box beam retaining wall casting cavity 6, and the casting operation is performed at the same time. When the concrete in the hopper 222 is insufficient, the material can be repeatedly transferred between the ground and the top surface of the box beam through the material distribution and casting vehicle 2 to complete the casting construction.

[0098] Embodiment 11 differs from Embodiment 10 in that it further includes step five: arranging at least one lifting platform mechanism 12 between two adjacent box girders 4 along the relative directions of the two adjacent box girders 4, and constructing a beam bridge road connecting the two adjacent box girders 4 by sequentially connecting the beam channels 1214 of at least one lifting platform mechanism 12; the material placing and pouring vehicle 2, the handling equipment 3 and the construction materials are transferred or transported through the beam bridge road.

[0099] The number of lifting platform mechanisms 12 can be flexibly arranged according to the width of the channel between two adjacent box girders 4, so that a bridge connecting the two adjacent box girders 4 can be quickly built at the channel between the two adjacent box girders 4, so that after the construction of one box girder retaining wall is completed, the construction equipment and construction materials can be quickly transferred and transported to the top surface of another adjacent box girder, which can significantly improve the construction efficiency and reduce the construction cost.

[0100] Specifically, the two lifting platform mechanisms 12 are arranged in sequence between two adjacent box girders 4 along the length direction of the box girder 4; the flip connecting plates 2 1212A and the flip connecting plates 3 1213A of the two lifting platform mechanisms 12 are flipped and opened to a horizontal state, and the flip connecting plates 2 1212A of one lifting platform mechanism 12 are connected to the flip connecting plates 3 1213A of the other lifting platform mechanism 12; the flip connecting plates 3 1213A of one lifting platform mechanism 12 and the flip connecting plates 2 1212 of the other lifting platform mechanism 12 are both placed on the top surface of the corresponding box girder 4 to form a beam bridge.

[0101] Specifically, after the construction is completed, the disassembled template can be loaded onto the vehicle plate 211 of the traveling vehicle body 21 by the handling equipment 3 for transportation.
