Description

Material distribution system and construction method for pouring concrete on high-storage surface of ship lock Technical Field

[0001] The invention relates to the technical field of ship lock concrete construction, in particular to a material distribution system and a construction method for pouring concrete on a high-storage surface of a ship lock. Background Art

[0002] A ship lock is a navigation structure in water transportation. Its cross-section is trough-shaped. The ship lock is mainly composed of upstream and downstream pilot channels, upper and lower gates and lock chambers. The upstream and downstream water level difference is adjusted by filling or draining water into the lock chamber, so that ships can rise and fall vertically between the upstream and downstream water levels, thereby keeping the waterway navigable normally.

[0003] A certain ship lock primarily uses low-slump, three-graded concrete for its pouring construction. The side walls of the ship lock are characterized by their length, width, and volume. Construction requires the side wall formwork to be constructed using integral steel formwork before the concrete is poured. This presents a challenge with high-slump concrete pouring. Concrete pump trucks are commonly used for this purpose, but conventional concrete pump trucks can only deliver concrete with a high slump (an indicator of concrete's water retention, fluidity, and cohesion), which cannot meet the construction requirements of three-graded concrete pouring. At present, the three-grade concrete pouring equipment mainly relies on crawler-type concrete placing machines, but the pouring angle of crawler-type concrete placing machines cannot exceed 25 degrees, and the pouring height is limited by the width of the gate chamber and the length of the conveyor belt on the crawler-type concrete placing machine. In addition, the pouring range at the fixed position is also limited, and the applicability is poor. In addition, when using crawler-type concrete placing machines for concrete pouring, the crawler-type concrete placing machines are set toward the side wall to facilitate forward or backward movement, thereby adjusting the warehouse entry position. However, when pouring the next warehouse surface station, it is necessary to turn the whole machine to move to the next station along the line direction, and then turn the direction toward the side wall for pouring operations. The pouring speed is about 70m 3 / h, the construction efficiency is low.

[0004] Summary of the Invention

[0005] The purpose of the present invention is to provide a material distribution system and construction method for pouring concrete on the high bunker surface of a ship lock, in order to solve the problems of low construction efficiency and narrow pouring range of three-graded concrete pouring equipment in the prior art.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is:

[0007] A material distribution system for pouring concrete on the high bunker surface of a ship lock comprises a lifting main frame, a bidirectional telescopic material distribution machine and a feeding belt conveyor, wherein the feeding belt conveyor is arranged along the longitudinal direction of the line, the bidirectional telescopic material distribution machine is arranged along the transverse direction of the line, the bidirectional telescopic material distribution machine is provided with a feeding port, the feeding belt conveyor is hingedly connected to the bidirectional telescopic material distribution machine, and the discharge end of the feeding belt conveyor is overlapped at the feeding port, the feeding end of the feeding belt conveyor can move relative to the ground along the longitudinal direction of the line, the lifting main frame is connected to the bidirectional telescopic material distribution machine via a lifting assembly, the lifting assembly is used to adjust the lifting height of the bidirectional telescopic material distribution machine, and a first walking mechanism is provided at the bottom of the lifting main frame, and the first walking mechanism is used to move along the longitudinal direction of the line;

[0008] The bidirectional telescopic material spreading machine includes a main frame and at least one telescopic belt frame, each telescopic belt frame is correspondingly equipped with a conveyor belt and a transverse driving device, the transverse driving device is used to drive the telescopic belt frame to move, and the conveyor belt is used to realize material transportation, the telescopic belt frame is slidably connected to the main frame, the telescopic belt frame can be cantilevered toward both ends of the main frame respectively, the main frame is slidably connected to the lifting main frame in the vertical direction, ensuring the relative movement stability between the telescopic belt frame and the main frame, and between the main frame and the lifting main frame.

[0009] Among them, the feeding end of the feeding belt conveyor can be movably contacted with the ground, or can be connected to the ground by rolling, or can be connected by a rotating pair and a slide rail mechanism. The specific structural form can be designed according to the actual working conditions to ensure that the feeding belt conveyor can move relative to the ground and can adapt to changes in casting height; in addition, the feeding belt conveyor can be either a whole-section structure or a segmented structure composed of multiple sections of belt conveyors.

[0010] This solution adopts a feeding belt conveyor arranged along the direction of the lock line to transfer concrete materials from the bottom end to the top end, and then transports the concrete materials horizontally to the retaining wall formwork on either side of the lock through a horizontally arranged two-way telescopic concrete distribution machine for concrete pouring; during the operation, the pouring height of the two-way telescopic concrete distribution machine can be adjusted by controlling the lifting component to achieve high-level pouring. When the maximum pouring angle of the belt conveyor is constant, the concrete pouring needs of higher levels can be met by lengthening the belt conveyor (including splicing and replacement), avoiding the influence of the pouring range of the distribution system on the limited width of the lock, and having good adaptability to working conditions; further, the extension length of the telescopic belt frame can be adjusted by the transverse drive device, that is, the transverse transport length of the concrete is changed to transport the concrete to the specified position, with a large pouring range and good applicability. There is no need to move the distribution system horizontally as a whole, and it is easy to use. When pouring the next station, the entire distribution system is directly driven by the first walking mechanism to move along the direction of the lock line, realizing full-station pouring operation, wide pouring coverage, and high construction efficiency.

[0011] The above-mentioned distribution system is used for pouring concrete on the high-storage surface of the ship lock. It is suitable for full-station construction of the ship lock with a small activity space on the construction site. It has good adaptability to working conditions, a large pouring coverage area, and high construction efficiency. Moreover, the distribution system can be arranged on the ship lock line for double-sided construction without destroying or occupying the surrounding environment.

[0012] As a preferred embodiment of the present invention, the above-mentioned material distribution system also includes an auxiliary bracket, the feeding belt conveyor includes a first-level belt conveyor and a second-level belt conveyor, the first-level belt conveyor is located between the lifting main frame and the auxiliary bracket, the discharge end of the second-level belt conveyor is arranged higher than the feeding end of the first-level belt conveyor and is located at the auxiliary bracket and overlapped with the first-level belt conveyor, so that the concrete material on the second-level belt conveyor can be transferred to the first-level belt conveyor; a second walking mechanism is provided at the bottom of the auxiliary bracket, and the auxiliary bracket is connected to the lifting main frame by a walking beam, and the auxiliary bracket is used to synchronously lift the feeding end of the first-level belt conveyor and the discharge end of the second-level belt conveyor.

[0013] The auxiliary bracket can be used to hook the overlapping ends of the two inclined belt conveyors for synchronous lifting, or the butt ends of the two inclined belt conveyors can be hingedly connected to lift either inclined belt conveyor. A slide rail mechanism can also be used to overlap the two inclined belt conveyors, and the slide rail mechanism can be driven by a motor to achieve height lifting, which is not limited to the above examples.

[0014] This solution utilizes two-stage inclined belt conveyors—a first-stage belt conveyor and a second-stage belt conveyor—for loading, extending the longitudinal transmission length and accommodating higher-level concrete pouring. This increases the pouring height while maintaining the same pouring angle. Furthermore, the segmented configuration of the two-stage inclined belt conveyors allows for more flexible and convenient transfers than a single-stage long belt conveyor, making it suitable for space-constrained ship lock sites. While using two-stage belt conveyors for segmented transport, this solution employs auxiliary supports to simultaneously elevate the connection between adjacent stages, increasing the overall loading height. This approach is simple to operate and offers excellent adaptability to various working conditions.

[0015] Furthermore, this solution connects the auxiliary support and the lifting main frame into a whole by fixing a walking beam between the auxiliary support and the lifting main frame, and cooperates with the first walking mechanism and the second walking mechanism to achieve overall movement; and the setting of the walking beam can also fix the distance between the auxiliary support and the lifting main frame, ensuring that both ends of the first-stage belt conveyor are securely connected and the inclination angle is stable during the walking process and the height lifting process, thereby avoiding large tensile stress in the structure of the first-stage belt conveyor.

[0016] To ensure normal functions, the second-stage belt conveyor should be able to rotate relative to the change of pouring height and move relative to the ground, and should not cause structural interference with the first-stage belt conveyor.

[0017] As a preferred embodiment of the present invention, the auxiliary bracket is provided with a mounting platform, the mounting platform is provided with a support column, the first-stage belt conveyor and the support column are hingedly connected, and the second-stage belt conveyor is hingedly connected to the mounting platform, so that the overlapping end of the second-stage belt conveyor is higher than the bottom end of the first-stage belt conveyor, facilitating material transmission; the auxiliary bracket is connected to the mounting platform via a lifting mechanism, and the lifting mechanism is used to adjust the height of the mounting platform. The lifting mechanism can be a winch and sling, a rack and pinion transmission, or a slide rail mechanism or other relative displacement adjustment method, and is not limited to the above examples.

[0018] As a preferred embodiment of the present invention, the mounting platform is slidably connected to the auxiliary bracket along at least one lateral side, and mechanical limiting is used to ensure stable ascent of the mounting platform, thereby preventing the conveyor belt from shaking. Furthermore, the auxiliary bracket is provided with a vertical slide rail along at least one lateral side, and claws are provided on corresponding sides of the mounting platform. The claws are slidably connected to the slide rails, and the slide rails and claws are provided with corresponding second pin mounting holes. When the mounting platform rises to a specified height along the slide rails, the pins are inserted into the corresponding second pin mounting holes on the slide rails and claws to achieve mechanical positioning, thereby ensuring stable and safe material transportation on the conveyor belt.

[0019] As a preferred solution of the present invention, a roller is provided at the bottom of the feeding end of the first-stage belt conveyor, and a roller is provided at the bottom of the feeding end of the second-stage belt conveyor, to facilitate movement and docking between multiple-stage belt conveyors.

[0020] As a preferred embodiment of the present invention, a connecting shaft is transversely mounted at the bottom of the discharge end of the feeding conveyor, and a bearing seat is mounted on the top of the bidirectional telescopic material distributor. The connecting shaft and the bearing seat are detachably connected, facilitating easy installation. During installation, the bearing seat can be opened, the connecting shaft at the bottom of the feeding conveyor inserted into the bearing seat, and then the cover is closed, enabling quick installation.

[0021] As a preferred embodiment of the present invention, the transverse drive device utilizes a rack and pinion transmission mechanism; the bidirectional telescopic fabric conveyor includes at least two telescopic belt frames—a first telescopic belt frame and a second telescopic belt frame. The first telescopic belt frame is disposed within the main frame, and the second telescopic belt frame is disposed within the first telescopic belt frame. The first telescopic belt frame is movable relative to the main frame and extends toward the cantilever arms at both ends of the main frame, while the second telescopic belt frame is movable relative to the first telescopic belt frame and extends toward the cantilever arms at both ends of the first telescopic belt frame. A rack and pinion transmission mechanism is employed between the main frame and the first telescopic belt frame, and between the second and first telescopic belt frames. Accordingly, the first telescopic belt frame is equipped with a conveyor belt and a transverse drive mechanism, and the second telescopic belt frame is also equipped with a conveyor belt and a transverse drive mechanism. The first and second telescopic belt frames move independently of each other.

[0022] In this solution, when the first section of the telescopic belt frame is driven to extend outward, the second section of the telescopic belt frame inside the first section of the telescopic belt frame can be driven to move synchronously, which has a simple structure, is easy to use, and has high construction efficiency. Moreover, the two-stage telescopic belt frame adopts gear rack engagement transmission, which is conducive to achieving two-way telescopic extension, that is, the first section of the telescopic belt frame can be extended to the left relative to the main frame, and can also be extended to the right relative to the main frame, thereby realizing the high-storage surface pouring operation of the lock retaining walls on both sides in sequence at a fixed position, with stable transportation, low operation difficulty, and good applicability to working conditions.

[0023] As other possible implementation methods, a one-stage telescopic belt rack or a three-stage or above telescopic belt rack can also be used, and the specific telescopic stages and lengths can be determined according to project needs.

[0024] As a preferred embodiment of the present invention, two V-shaped slides are provided on the upper and lower inner sidewalls of the main frame, and diamond-shaped pipes are provided at the four corners of the first telescopic belt frame. These diamond-shaped pipes cooperate with the V-shaped slides. These diamond-shaped pipes and the V-shaped slides provide guidance and support, enabling the transverse drive device to enable the first telescopic belt frame to move left and right relative to the main frame. Furthermore, the V-shaped slides prevent concrete from splashing onto the slide mating surfaces and affecting transportation.

[0025] As a preferred solution of the present invention, a material baffle is provided in the main frame, and the material baffle is arranged along the length direction of the main frame to prevent concrete materials from splashing during transportation and thus affecting the gear rack transmission.

[0026] As a preferred solution of the present invention, the feed port is located in the middle of the main frame or near either lateral end, preferably near either lateral end, leaving a larger space for convenient vehicle passage; a guide plate is provided on the surrounding side of the feed port, which is used to guide the concrete material transmitted by the first-stage belt conveyor into the conveyor belt conveyor of the first section of the telescopic belt frame, while preventing material splashing.

[0027] As a preferred embodiment of the present invention, the main lifting frame is provided with guide rails along two opposing lateral sides, and the main frame is provided with a pin holder at each end. The pin holder is slidably connected to the guide rails and is detachably connected to the main frame. The sliding fit between the pin holder and the guide rails ensures stable lifting of the bidirectional telescopic material spreading machine, preventing shaking during the lifting process. By detachably connecting the pin holder to the main frame, this embodiment facilitates easy adjustment of the pin holder's installation position to adapt to the guide rails, providing flexible installation and convenient use.

[0028] As a preferred embodiment of the present invention, the pin holders and the guide rails are provided with corresponding first pin mounting holes. When the bidirectional telescopic concrete placing boom is raised to a specified height along the main lifting frame, the pins are inserted into the corresponding first pin mounting holes in the guide rails and pin holders on both sides of the main lifting frame to achieve mechanical positioning, ensuring stable and safe transportation during high-floor concrete pouring operations.

[0029] As a preferred solution of the present invention, ladders are provided on both sides of the lifting main frame to facilitate maintenance and pin insertion and removal by construction workers.

[0030] As a preferred embodiment of the present invention, the main lifting frame is a portal structure, comprising two support leg columns connected by a crossbeam. A load-bearing beam is provided at the bottom of each support leg column along the longitudinal direction of the line. The first traveling mechanism is located at the bottom of the load-bearing beam. An auxiliary support is provided between the load-bearing beam and the main lifting frame, and the auxiliary support is located on the back of the main lifting frame. The main lifting frame used in this embodiment is simple, stable, and easy to move.

[0031] As a preferred solution of the present invention, the above-mentioned material distribution system further includes a guide rail, which is laid along the longitudinal direction of the lock, and the first traveling mechanism travels along the guide rail.

[0032] As a preferred solution of the present invention, a limiting device is detachably mounted on the guide rail, the limiting device is used to detect the moving position of the bottom end of the feeding belt conveyor, and the limiting device is communicatively connected with the lifting assembly.

[0033] The present invention also provides a construction method for pouring concrete on the high-storage surface of a ship lock, comprising the following steps:

[0034] Using the above-mentioned material placing system, the bidirectional telescopic material placing boom is lifted to the specified height;

[0035] Extend the telescopic belt frame to drive the feeding belt conveyor and the corresponding conveyor belt conveyor on the bidirectional telescopic concrete placing machine to perform concrete pouring operations;

[0036] After the concrete pouring operation at the current workstation is completed, the first traveling mechanism is driven to move the material distribution system to the next workstation.

[0037] The above construction method is used for the concrete pouring construction of the high-storage surface of the ship lock. It has high construction efficiency, a large pouring range, good applicability, does not occupy the surrounding environment land (the sites on both sides of the ship lock), and is environmentally friendly.

[0038] As a preferred embodiment of the present invention, the above-mentioned construction method further includes the steps of: placing a limit device on the lock line; when the feeding conveyor triggers the limit device, the lifting of the bidirectional telescopic concrete placing boom is stopped. The limit device can prevent the feeding conveyor from tilting too much, which can affect the conveying efficiency of the concrete material and even cause the concrete material to fall back. The placement of the limit device can be selected according to actual needs.

[0039] As a preferred embodiment of the present invention, the above construction method further includes the steps of mechanically positioning the bidirectional telescopic fabric crane at a specified height and releasing the positioning to ensure construction safety and transportation stability.

[0040] As a preferred embodiment of the present invention, the above construction method further comprises the step of performing pouring operation on a higher silo surface by lengthening the feeding belt conveyor:

[0041] First, install an auxiliary bracket at the feeding end of the first-stage belt conveyor, and fix the auxiliary bracket to the lifting main frame through the walking beam;

[0042] A mounting platform is installed on the auxiliary bracket so that the mounting platform can move vertically, a feeding end of the first-stage belt conveyor is hingedly arranged on the mounting platform, and a second-stage belt conveyor is added to the mounting platform, a discharging end of the second-stage belt conveyor is hingedly connected to the mounting platform, and the second-stage belt conveyor is overlapped with the first-stage belt conveyor;

[0043] The installation platform is lifted while continuing to lift the bidirectional telescopic concrete placing boom, thereby increasing the pouring height.

[0044] This solution uses a multi-stage belt conveyor for loading in the line direction. The structure is not easy to deform, which is conducive to the stable transportation of concrete. In addition, the short-segment belt conveyor is lighter than the full-section long belt conveyor, which is convenient for transportation and quick installation. It takes up less space and is flexible and convenient to transfer.

[0045] This solution uses an installation platform to connect the multi-stage belt conveyors to achieve synchronous lifting. During the lifting process, the installation platform and the auxiliary bracket cooperate with each other to ensure the relative stability of the multi-stage belt conveyors and prevent dislocation. At the same time, the main lifting frame is used to synchronously lift the discharge end of the first-stage belt conveyor (or the two-way telescopic concrete placing machine), realizing the overall lifting of the feeding belt conveyor and the two-way telescopic concrete placing machine, thereby adapting to the casting needs of higher warehouse surfaces.

[0046] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0047] 1. The material distribution system provided by the present invention is suitable for the high-storage concrete pouring operation of the ship lock, with a large pouring height range, a wide coverage area, good adaptability to working conditions and high construction efficiency.

[0048] 2. The material distribution system provided by the present invention has a simple structure, flexible transition, easy use, small site occupation and low operation difficulty.

[0049] 3. The material distribution system provided by the present invention is used for the high-storage surface concrete pouring operation of the ship lock. It only needs to be arranged along the direction of the ship lock line, without destroying or occupying the surrounding environment, and is environmentally friendly.

DETAILED DESCRIPTION

[0066] The present invention will be described in detail below with reference to the accompanying drawings.

[0067] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0068] Example 1

[0069] The present embodiment provides a material distribution system for pouring concrete on the high-storage surface of a ship lock, as shown in Figures 1 to 10. The material distribution system includes a lifting main frame 1, a two-way telescopic material distribution machine 2, and a feeding belt conveyor 3. The feeding belt conveyor 3 is tilted along the longitudinal direction of the line for longitudinal transportation; the two-way telescopic material distribution machine 2 is set along the transverse direction of the line for transverse transportation, and can be telescopically distributed to either side of the transverse direction; the discharge end of the feeding belt conveyor 3 is set higher than the two-way telescopic material distribution machine 2 and the discharge end of the feeding belt conveyor 3 is hingedly connected to the two-way telescopic material distribution machine 2. The feeding belt conveyor 3 is used to transfer the lower end concrete material upward to the two-way telescopic material distribution machine 2, and then the two-way telescopic material distribution machine 2 transports it transversely to the side wall formwork. When the two-way telescopic material distribution machine 2 moves, it will also drive the feeding belt conveyor 3 to move together. Furthermore, the main lifting frame 1 is connected to the bidirectional telescopic fabric conveyor 2 via a lifting assembly. The lifting assembly is used to adjust the lifting operation of the bidirectional telescopic fabric conveyor 2. As the height of the bidirectional telescopic fabric conveyor 2 changes, the feeding belt 3 rotates relative to the bidirectional telescopic fabric conveyor 2. During the ascent of the bidirectional telescopic fabric conveyor 2, the feeding belt 3 should avoid interfering with the structure of the bidirectional telescopic fabric conveyor 2 within the allowable tilt range. A first traveling mechanism is provided at the bottom of the main lifting frame 1. The first traveling mechanism is used to move along the longitudinal direction of the line, and the first traveling mechanism drives the entire fabric conveyor system to move. The bidirectional telescopic fabric conveyor 2 includes a main frame 21 and at least one telescopic belt frame. Each telescopic belt frame is equipped with a feeder belt and a transverse drive device. The transverse drive device is used to drive the telescopic belt frame to move, and the feeder belt is used to transport materials. The telescopic belt frame is slidably connected to the main frame 21, and the main frame 21 is slidably connected to the main lifting frame 1, ensuring the stability of the relative movement between the telescopic belt frame and the main frame 21, and between the main frame 21 and the main lifting frame 1.

[0070] Specifically, in this embodiment, the feeding conveyor 3 has rollers (not shown) installed at the bottom of the frame at the feeding port, allowing it to move along the route. As shown in Figure 3, a connecting shaft 33 is installed transversely at the bottom of the frame at the discharge port of the feeding conveyor 3. Accordingly, the bidirectional telescopic material distributor 2 is equipped with a bearing seat 26 at the top of the main frame 21. The connecting shaft 33 is removably mounted within the bearing seat 26, making installation and removal quick and easy. During installation, the bearing cover 27 is opened, the connecting shaft 33 at the bottom of the feeding conveyor 3 is inserted into the bearing seat 26, and then the cover is closed, achieving quick installation.

[0071] As shown in Figures 2, 4, and 5, the bidirectionally telescopic material placing boom 2 in this embodiment comprises two telescopic belt frames—a first telescopic belt frame 22 and a second telescopic belt frame 23. Each telescopic belt frame is equipped with a feeder belt and a transverse drive. The two telescopic belt frames move independently of each other and can both transversely extend and retract in both directions. Their combined telescopic range is 0-26.5 meters, sufficient to cover all surfaces on both sides of the lock. Specifically, the transverse drive in this embodiment preferably employs a rack-and-pinion transmission mechanism. Specifically, the cross-sections of the main frame 21 and the telescopic belt frame are roughly rectangular, and both ends are open structures for the cantilever of the nested telescopic belt frame to extend; the first section telescopic belt frame 22 is nested inside the main frame 21, and diamond-shaped pipes are welded at the four corners of the first section telescopic belt frame 22. A rack structure is provided on the front and rear outer walls of the first section telescopic belt frame 22 along the length direction. Correspondingly, the upper and lower side walls of the main frame 21 are respectively provided with V-shaped slides 25. The V-shaped slides 25 cooperate with the diamond-shaped pipes, and cement is not easily splashed into the V-shaped slides 25. Furthermore, a drive motor is installed on the front and rear outer surfaces of the main frame 21, and the drive shaft of the drive motor passes through the side walls of the main frame 21 and is connected to the drive gear. The drive gear on the main frame 21 engages with the rack on the first section telescopic belt frame 22; by controlling the forward and reverse rotation of the drive motor, the left and right movement of the first section telescopic belt frame 22 is achieved under the action of the gear rack engagement transmission. Similarly, the second telescopic belt frame 23 is nested inside the first telescopic belt frame 22. Two rows of V-shaped slideways 25 are provided on the upper and lower sides of the first telescopic belt frame 22, respectively, which are slidably connected to the second telescopic belt frame 23. Racks are provided along the length of the inner side walls of the front and rear of the first telescopic belt frame 22, and gears are provided on the front and rear sides of the second telescopic belt frame 23 for meshing with the racks on the opposite sides. The drive motor is hidden inside the second telescopic belt frame 23. When the first telescopic belt frame 22 is driven to extend outward, it can drive the second telescopic belt frame 23 inside the first telescopic belt frame 22 to move synchronously. This is simple to operate and easy to use, which helps improve construction efficiency.

[0072] Furthermore, a feed port is provided at the top of the main frame 21. In this embodiment, the feed port is arranged close to the left side of the main frame 21 to facilitate the passage of vehicles. Accordingly, the position of the conveyor belt on the first section telescopic belt frame 22 should always be coordinated with the position of the feed port. At this time, the maximum length of the cantilever extending toward the left of the bidirectional telescopic fabricating machine 2 is greater than the maximum length of the cantilever extending toward the right, but it is sufficient to cover the retaining wall construction warehouse surface on both sides of the ship lock. Furthermore, a guide plate is provided on the peripheral side of the feed port. The bottom end of the guide plate corresponds to the conveyor belt on the outermost first section telescopic belt frame 22, and is used to guide the concrete material transmitted by the first-stage belt conveyor 31 to the conveyor belt of the first section telescopic belt frame 22, while preventing the material from splashing. A material baffle (not shown in the figure) is also provided in the main frame 21. The material baffle is arranged along the length direction of the main frame 21 to protect the smooth transmission of the gear rack and prevent the concrete material from splashing in.

[0073] As shown in Figures 1 and 2, the main lifting frame 1 in this embodiment is a gantry-like structure, arranged transversely along the lock. The main lifting frame 1 includes two support leg columns 13, connected by two crossbeams. A load-bearing beam 14 is provided at the bottom of each support leg column 13, running longitudinally along the line. The load-bearing beam 14 utilizes a box-shaped beam structure welded from steel plates and should possess sufficient load strength. Three sets of drive wheel assemblies are located at the bottom of each load-bearing beam 14, resulting in a total of six drive wheel assemblies for the entire main lifting frame 1, serving as the first traveling mechanism. Two sets of drive wheel assemblies are located at the heavy-load end of the load-bearing beam 14, and one set of drive wheel assemblies is located at the light-load end of the load-bearing beam 14. Each drive wheel assembly consists of a drive wheel box, two sets of drive wheel assemblies, and a drive reduction motor. The entire concrete gantry self-elevating bidirectional material distribution system travels longitudinally along the guide rails, with all driving power provided by the drive wheel assemblies. Due to the heavy load capacity of the drive wheel assembly, each set of drive wheels in this embodiment utilizes dual wheels. These wheels are mounted slightly forward of the bottom of the outrigger columns 13, effectively enhancing the overall stability of the machine during conveyor operation. Each load-bearing beam 14 is connected to the corresponding outrigger column 13 by an auxiliary support 15. The auxiliary supports 15 are located on the back of the main lifting frame 1, forming a stable triangle. All auxiliary supports 15 have a minimum clearance of at least 8 meters above the ground to ensure easy and efficient passage of on-site construction vehicles. The outrigger columns 13 in this embodiment consist of three sections: a bottom section, a middle section, and a top section. All sections of the outrigger columns 13 were repurposed from existing steel tubular trusses on the project site. The existing steel tubular trusses have a rectangular cross-section, with a main chord center distance of 2.3m x 1.2m. The main chord steel pipes are all φ219 x 10mm steel pipes. The cross-sectional dimensions of the steel pipes and trusses are sufficiently large to meet the load requirements of the conveyor belt hoist.

[0074] Furthermore, the lifting assembly in this embodiment utilizes a winch and pulley mechanism. The pulley mechanism primarily consists of two sets of movable pulley blocks 28, two sets of fixed pulley blocks 16, two sets of guide pulley blocks, and two steel cables. A schematic diagram of the wire rope winding of the lifting assembly is shown in Figure 11. The two sets of movable pulley blocks 28 are mounted on top of the bidirectional telescopic concrete fabric boom 2, directly in front of the outrigger columns 13, with a lateral spacing of 16 meters between the two sets of movable pulley blocks 28. Two sets of fixed pulley blocks 16 are mounted on top of the outrigger columns 13 on either side, and two sets of guide pulley blocks 17 are mounted on the load-bearing beam 14. Two steel cables connect the two sets of movable and fixed pulley blocks 16 and the guide pulley blocks 17 in series, achieving vertical synchronous lifting and lowering of the bidirectional telescopic concrete fabric boom 2. The winch is mounted directly above the end of the load-bearing beam 14 on one side. The winch in this embodiment adopts a symmetrical dual output shaft, and is equipped with a set of wire rope drums on the left and right sides of the winch. The two wire ropes in the lifting assembly are respectively wound on the two drums on the left and right sides of the winch through the guide pulley group 17, ensuring the synchronous lifting operation of the bidirectional telescopic fabric placing boom 2 during the lifting process.

[0075] Furthermore, as shown in Figures 6-10, to ensure the stable ascent of the telescopic fabric boom 2 during the hoisting operation, a set of guide rails 11 are installed on the outer sides of the left and right support leg columns 13 of the main lifting frame 1. These guide rails 11 serve to guide the telescopic fabric boom 2 during the vertical hoisting operation. Accordingly, a pin holder 24 is installed at each end of the telescopic fabric boom 2. In this embodiment, the pin holder 24 is removably connected to the main frame 21. The pin holder 24 is welded from multiple steel plates and has an overall rectangular ring shape that is sleeved onto the main frame 21. The pin holder 24 has a claw facing the support leg column 13. The claw has a first pin mounting hole 241 and a concave groove 242 on the inner side of the claw. The grooves 242 on the pin holders 24 at both ends are arranged opposite each other and mate with the guide rails 11. The guide rail 11 is arranged with a row of first pin mounting holes 241 from top to bottom, with a height difference of 1 meter between all of them. Two more first pin mounting holes 241 are also reserved on the claws of the pin holder 24, with a height difference of 2 meters. To meet the height requirements for material distribution, after the two-way telescopic material distribution boom 2 is raised into position, a mechanical pin is installed between the claws and the guide rail 11. This mechanically connects the two-way telescopic material distribution boom 2 to the leg columns 13, reducing the load requirements of the lifting assembly and improving the safety and stability of the entire machine.

[0076] During the actual guided lifting process, the first pin shaft mounting hole may be aligned on one side. At this time, first align the two pin shafts on one side, and then jog the winch in the direction of unloading or loading the wire rope: When the first pin shaft mounting hole on the other side claw is higher than the first pin shaft mounting hole on the guide rail 11, jog the winch in the direction of unloading the wire rope; when the first pin shaft mounting hole on the claw is lower than the first pin shaft mounting hole on the guide rail 11, jog the winch in the direction of loading the wire rope; after the four pin shafts are fully installed, the winch can be unloaded.

[0077] Accordingly, a ladder 12 is installed on the outside of each leg column 13. Several platforms are arranged from bottom to top within the leg columns 13, with a height difference of 2 meters between the platforms, meeting the construction requirements of the material distribution belt conveyor from bottom to top. After the bidirectional telescopic material distribution boom 2 is raised to the required height, workers climb the ladder 12 to the platform where the bidirectional telescopic material distribution boom 2 is located and manually remove and insert the load-bearing pin between the clamping claw and the guide rail 11.

[0078] Furthermore, the above-mentioned material distribution system also includes guide rails and a limit device. The guide rails are laid along the direction of the lock line. The support leg columns 13 on both sides of the lifting main frame 1 and the rollers 34 at the bottom of the feeding conveyor 3 are each equipped with corresponding guide rails for guidance, ensuring stable operation of the entire machine. The limit device is removably mounted on the ground and corresponds to the maximum tilt position of the feeding conveyor 3. The limit device is communicatively connected to the winch. The limit device is used to detect the moving position of the bottom end of the feeding conveyor 3. When the bottom end of the feeding conveyor 3 triggers the limit device, the winch stops, preventing the lifting assembly from further lifting, preventing the feeding conveyor 3 from interfering with the bidirectional telescopic material distribution machine 2, and ensuring that the feeding conveyor angle does not exceed 22°. Otherwise, the material will fall back when the feeding conveyor conveys concrete. This ensures the quality of concrete pouring. The limit device can adopt a conventional travel switch, or it can also adopt a pressure sensor, distance meter, etc.

[0079] The construction process is described as follows:

[0080] S1. First, the bidirectional telescopic fabric machine 2 is lifted along the guide rail 11 to a specified height, and the bidirectional telescopic fabric machine 2 is fixed to the guide rails 11 on both sides by the pin;

[0081] S2. Keep the second section of the telescopic belt rack 23 centered within the first section of the telescopic belt rack 22 and do not move, driving the first section of the telescopic belt rack 22 to the left (or right);

[0082] S3 then drives the feeding belt conveyor 3 and the first section of the telescopic belt frame 22 on the feed belt conveyor, and starts the fabric operation on the outer retaining wall;

[0083] S4. As the concrete accumulates, the first section of the belt frame retracts into the main frame 21, the fixed pin is pulled out, and the winch lifts the bidirectional telescopic concrete placing boom 2 vertically along the guide track 11 of the lifting main frame 1 to the appropriate height. The fixed pin is then reinserted to continue the concrete placing operation. The number of extension sections and length of the telescopic belt frame can be selected according to the specific working conditions.

[0084] After the concrete pouring operation at the current position is completed, the driving mechanism moves the material distribution system to the next work station to continue construction. The material distribution system in this embodiment can be applied to various working conditions and is not limited to the above examples.

[0085] This solution uses a feeding belt conveyor 3 arranged along the direction of the lock line to transport concrete materials from the bottom to a higher point. The concrete materials are then transported horizontally to the lock side wall by a horizontally arranged two-way telescopic concrete distributor 2 for concrete pouring. The pouring of concrete mainly relies on the cooperation of the belt conveyors, and the drive of the belt conveyors can be remotely controlled by one person through an automated control system. During operation, the two-way telescopic concrete distributor 2 can be adjusted to a specified height for pouring operations according to construction requirements. The pouring position of the entire machine can also be adjusted by driving the walking mechanism to meet the operational requirements of concrete pouring at all workstations in the lock head and lock chamber. Compared with existing three-level distribution pouring equipment, the efficiency of this distribution system has been significantly improved, with high operating efficiency, stable performance, wide pouring coverage, good adaptability to working conditions, and high versatility.

[0086] Example 2

[0087] Based on Example 1, this embodiment also provides a material distribution system for pouring concrete on the high-level surface of a ship lock, as shown in Figures 12 to 15. The main difference between this embodiment and Example 1 is that by extending the feeding belt conveyor 3, the high-level belt conveyor and the low-level belt conveyor are lifted as a whole to meet the concrete pouring needs of a higher level surface.

[0088] Specifically, the material distribution system in this embodiment features two stages of loading conveyors 3: a first-stage conveyor 31 and a second-stage conveyor 32. The first-stage conveyor 31 is hingedly connected to the main hoist frame 1, while the discharge end of the second-stage conveyor 32 overlaps the loading end of the first-stage conveyor 31. Rollers 34 are also installed at the bottom of the loading end frame of the second-stage conveyor to facilitate movement along the route. The second-stage conveyor 32 can rotate relative to the first-stage conveyor 31, enabling concrete pouring operations at higher silos without dismantling the first-stage conveyor 31. To achieve synchronous lifting of the two adjacent conveyor stages at the junction and to ensure stable lifting at this junction, the material distribution system in this embodiment is equipped with a gantry-type auxiliary support 4 at the loading end of the first-stage conveyor 31. This auxiliary support 4 is used to synchronously lift the loading end of the first-stage conveyor 31 and the discharge end of the second-stage conveyor 32. The auxiliary support 4 can be modified from an existing gantry crane, with a span of 16 meters and a rated load of 30 tons. A second traveling mechanism is provided at the bottom of the auxiliary support 4. The second traveling mechanism adopts an unpowered driven wheel set. The auxiliary support 4 is fixedly connected to the main lifting frame 1 via a traveling beam 5. The main lifting frame 1 provides a driving power source for the entire material distribution system. The main lifting frame 1 drives the auxiliary support 4 to move together through the traveling beam 5. More specifically, the loading end of the first-stage belt conveyor 31 and the discharging end of the second-stage belt conveyor 32 are both hinged on a mounting platform 6. A support column 61 is provided on the side of the mounting platform 6 close to the second-stage belt conveyor 32. The two sides of the second-stage belt conveyor are respectively hingedly connected to a support column 61. The first-stage belt conveyor is hingedly connected to the main body of the mounting platform 6, so that the discharging end of the second-stage belt conveyor is higher than the loading end of the first-stage belt conveyor, preventing structural interference during the lifting process and ensuring smooth transportation of concrete materials. Furthermore, the mounting platform 6 is connected to the auxiliary support 4 via a lifting mechanism, and the lifting mechanism is used to adjust the lifting height of the mounting platform 6. In this embodiment, the lifting mechanism preferably adopts a winch and a sling, and the winch is fixedly installed on the upper part of the auxiliary bracket 4, and then the installation platform 6 is lifted up by using multiple slings; accordingly, at least one side of the auxiliary bracket 4 is vertically provided with a slide rail 41 and is equipped with a ladder 12 on the side. A row of second pin shaft mounting holes is provided on the slide rail 41 from bottom to top, and a U-shaped claw is provided on the corresponding side of the installation bracket. The claw slides with the slide rail 41 to ensure that the lifting process of the sling is stable and does not shake. A second pin shaft mounting hole is also provided on the claw. When the installation platform 6 is lifted to the specified height, the pin shaft is inserted into the second pin shaft mounting hole for mechanical positioning, which reduces the load-bearing requirements of the sling and improves the safety and stability of the lifting mechanism.

[0089] In order to solve the problem of vertical transportation of three-graded concrete, this embodiment is designed to cooperate with two inclined belt conveyors, namely the first-stage belt conveyor 31 and the second-stage belt conveyor 32, to lengthen the longitudinal transmission length, which can adapt to the concrete pouring construction of higher warehouse surfaces. The pouring height is increased within the limit of the maximum pouring angle (the maximum inclination angle of the loading belt conveyor 3 in this embodiment is designed to be about 22°), and the pouring height can reach 32m. Moreover, the use of two-stage inclined belt conveyors in sections is more flexible and convenient than the use of a whole-stage long belt conveyor, and is suitable for situations where the space of the ship lock site is limited. In the case of using two-stage belt conveyors for segmented transportation, this solution uses an auxiliary bracket 4 to synchronously lift the connecting part of the adjacent two-stage belt conveyors, which can achieve the height increase of the overall loading, simple operation, and good adaptability to working conditions.

[0090] Example 3

[0091] Based on the material distribution system provided in Example 2, this embodiment also provides a construction method for pouring concrete on the high bunker surface of a ship lock, which is suitable for vertical transportation operations on the high bunker surface. As shown in Figure 13, the material distribution process on the bunker surface at the top of the ship lock is used as an example:

[0092] S1. First, arrange a limit device, such as a travel switch, at the first position of the travel route of the first-stage belt conveyor 31. The first position in this embodiment corresponds to the maximum allowable inclination angle of 20.5° designed for the first-stage belt conveyor 31, and a certain margin is reserved. The setting of the first position can be selected according to construction needs.

[0093] S2. Slowly lift the bidirectional telescopic fabric conveyor 2 from low to high until the first-stage belt conveyor 31 triggers the limit device and the winch stops working. Fix the first-stage belt conveyor 31 and the guide rail 11 through the fixing pin.

[0094] S3. Remove the limiting device at the first position, erect an auxiliary support 4 at the end of the first-stage conveyor belt 31, and securely connect the auxiliary support 4 to the main lifting frame 1 via the travel beam 5. Overlap the second-stage conveyor belt 32 with the first-stage conveyor belt 31 at the auxiliary support 4 via the mounting platform 6. Simultaneously, install a limiting device at a second position along the travel path of the second-stage conveyor belt 32. In this embodiment, the second position corresponds to the maximum allowable rotation angle of the second-stage conveyor belt 32. Similarly, the second position setting can be adjusted manually based on construction requirements.

[0095] S4. Pull out the fixed pin and continue to lift the two-way telescopic fabric conveyor 2. At the same time, based on the auxiliary bracket 4, the mounting platform 6 is simultaneously lifted. That is, while the first-stage belt conveyor 31 is lifted as a whole, the discharge end of the second-stage belt conveyor 32 is lifted synchronously with the first-stage belt conveyor until the two-way telescopic fabric conveyor 2 is raised to the specified height and fixed again with the pin.

[0096] S5. Placing operation: outward moving the first section telescopic belt rack 22 and the second section telescopic belt rack 23, driving the first section telescopic belt rack 22 and the second section telescopic belt rack 23 on the conveyor belt, as well as the first and second stage belt conveyors 31 and 32, to achieve three-level concrete high silo surface transport pouring.

[0097] S6. After the concrete pouring operation at the current station is completed, the concrete transportation operation is stopped, the extended telescopic belt frame is retracted, and the first traveling mechanism is driven to move the material distribution system to the next station to continue material distribution.

[0098] The concrete placing system in this scheme adopts the self-developed ship lock concrete gantry self-elevating two-way placing system. After the track is arranged, it can directly cover the pouring height of the ship lock concrete, and the pouring speed is expected to reach 120-140m 3 A comprehensive comparative analysis shows that adopting this solution for vertical transportation on the high-rise floor can double the efficiency of concrete pouring, providing a favorable guarantee for the smooth completion of the project.

[0099] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
