[0024] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example 1:

[0027] like Figures 1-4 As shown, a high-speed railway concrete placing boom includes a mobile frame 1, a placing hopper 2 installed on the mobile frame, a partition 3 installed inside the placing hopper, the partition dividing the placing hopper into two storage chambers 4, a first discharge port 6 and a second discharge port 7 respectively installed on the mobile frame corresponding to the two storage chambers, a first discharge slide 8 and a second discharge slide 9 detachably installed on both sides of the mobile frame, the tops of the first discharge slide 8 and the second discharge slide 9 being connected to the first discharge port and the second discharge port respectively, a mixing discharge port 10 for discharging the mixed material from the two storage chambers is also installed on the mobile frame at a position corresponding to the bottom of the placing hopper, and a third discharge slide 11 is also installed on the mobile frame at a position corresponding to the first discharge port and the second discharge port, the third discharge slide 11 being used to guide the material from the first discharge port and the second discharge port to the mixing discharge port.

[0028] As a preferred embodiment, the baffle 3 is arranged in a conical shape, and a vibrator 5 is installed on the mobile frame 1 corresponding to the bottom of the feeding hopper. This structural design has the following advantages: ① Smoother material discharge: The conical arrangement of the baffle guides the material to flow towards the discharge port at the bottom of the feeding hopper, preventing material accumulation and residue within the hopper. Especially for concrete materials with poor flowability, the conical baffle acts as a guide, allowing the material to enter the discharge port more smoothly. ② Better mixing effect: The vibrator is installed on the mobile frame corresponding to the bottom of the feeding hopper. When the material is discharged through the mixing discharge port, the vibration generated by the vibrator promotes thorough mixing of the two materials. The vibration breaks up agglomerates between materials, allowing the materials in different storage chambers to be more evenly integrated, thereby improving the quality and performance of the concrete. ③ Reduced risk of blockage: The vibration of the vibrator also prevents blockage of the material at the discharge port and in the discharge chute. During the conveying process, concrete materials may adhere to the inner wall of the pipe or chute due to viscosity or other reasons, leading to poor discharge or even blockage. Vibration can cause the attached material to detach, ensuring the continuity and stability of material conveying.

[0029] As a preferred implementation, the first discharge chute 8, the second discharge chute 9, and the third discharge chute 11 are all U-shaped troughs. This structural design offers the following advantages: ① Prevents material leakage: The U-shaped trough's structure confines material within the trough during transport, preventing spillage from the sides. This not only avoids material waste but also maintains a clean construction site, reducing cleaning work. ② Enhanced wear resistance: Compared to other shaped chutes, the U-shaped trough has a more robust structure and better wear resistance when subjected to material impact and friction. This extends the service life of the discharge chutes and reduces equipment maintenance costs. ③ Facilitates installation and disassembly: The regular shape of the U-shaped trough facilitates installation and disassembly with the mobile frame. When the discharge chutes need replacement or cleaning, it can be done more easily and quickly, reducing equipment downtime.

[0030] As a preferred embodiment, drive wheel sets 12 are installed at the four corners of the bottom of the mobile frame, and each drive wheel set is equipped with a drive motor 13. This structure offers the following advantages: ① Flexible operation: Each drive wheel set is equipped with a drive motor, making the concrete placing boom more flexible in its movement. By independently controlling the speed and direction of each drive motor, the concrete placing boom can perform various actions such as forward movement, backward movement, and turning, better adapting to the complex terrain and working environment of high-speed rail construction sites. ② Precise positioning: The drive motors have high control precision, accurately controlling the rotation angle and speed of the drive wheels. This allows the concrete placing boom to achieve precise positioning when reaching the designated placement position, improving the accuracy and efficiency of the placement. ③ Space saving: The drive motors are directly installed in the hubs of the drive wheels, eliminating the need for additional transmission devices, reducing the equipment's footprint and overall weight. This is of great significance for high-speed rail construction sites operating in confined spaces.

[0031] As a preferred embodiment, the first discharge chute 8 and the second discharge chute 9 are equipped with multiple lifting bolt holes 14 along their length, allowing the lengths of the first and second discharge chutes to be adjusted. This structure offers the following advantages: ① Adjustable length: Discharge chute segments of different lengths can be easily connected via the lifting bolt holes, thus changing the lengths of the first and second discharge chute. The length of the discharge chute can be flexibly adjusted according to actual needs in different construction scenarios to meet different concrete placement range and distance requirements. ② Adaptability to different working conditions: The terrain and operational requirements of high-speed rail construction vary, and some construction locations may require longer discharge chutes to transport concrete to designated locations. The design of the lifting bolt holes allows the concrete placing boom to quickly adapt to these different working conditions, improving the equipment's versatility and adaptability. ③ Convenient transportation and storage: When transporting and storing the concrete placing boom, the discharge chute can be disassembled into shorter segments, reducing space occupation, transportation costs, and storage difficulty.

[0032] As a preferred embodiment, a guide wheel assembly is also installed at the bottom of the mobile frame. The guide wheel assembly includes an adjusting arm 16 that can be raised and lowered and slidably mounted on the mobile frame. A guide wheel frame 15 is installed at the bottom of the adjusting arm, and a guide wheel 17 is rotatably mounted on the guide wheel frame, which rolls in cooperation with the side of the high-speed rail track. A telescopic adjuster 18 is also installed on the mobile frame, such as a telescopic adjusting screw; one end of the telescopic adjuster is hinged to the guide wheel frame, and the other end of the telescopic adjuster is hinged to the mobile frame. The above structure has the following advantages: ① Ensuring walking stability: The guide wheels of the guide wheel assembly roll in cooperation with the side of the high-speed rail track, which can guide the concrete placing machine to walk stably along the track. During the movement, the guide wheels can prevent the concrete placing machine from deviating, ensuring the accuracy of the equipment's walking direction and improving the safety and stability of construction. ② Adapting to track changes: The telescopic adjuster can adjust the position of the guide wheel frame, so that the guide wheels can be adjusted according to the actual conditions of the high-speed rail track. When the track has a certain slope, bend, or unevenness, the telescopic adjuster can adjust the pressure and position of the guide wheels in time to ensure that the guide wheels always maintain good contact with the track, so that the concrete placing machine can smoothly pass through various track conditions. ③ Improve equipment adaptability: By adjusting the height and position of the guide wheel assembly, the concrete placing boom can adapt to different specifications and models of high-speed rail tracks. This increases the equipment's applicability and enhances its market competitiveness.

[0033] This high-speed rail concrete placing boom achieves efficient and flexible concrete placing operations through its unique structural design and optimized technical solutions. The following will detail its implementation method, including the overall structure of the equipment, the installation of its components, and its operation.

[0034] I. Overall Equipment Structure and Installation

[0035] (I) Installation of the mobile frame and fabric hopper

[0036] The mobile frame, serving as the load-bearing foundation of the entire equipment, is welded from high-strength steel to ensure sufficient strength and stability. A feeding hopper is bolted to a suitable location at the top of the mobile frame. Inside the hopper, a conical baffle divides the hopper into two storage chambers. This conical baffle design helps material concentrate at the bottom of the hopper, reducing material residue, and also facilitates the convergence and mixing of two different materials at the mixing outlet.

[0037] (II) Installation of discharge port and discharge chute

[0038] On the mobile frame, a first discharge port and a second discharge port are respectively opened in the two storage chambers corresponding to the material hopper. The first and second discharge ports are connected to the bottom of the storage chambers to facilitate smooth material discharge. On both sides of the mobile frame, a first discharge slide and a second discharge slide are detachably installed with bolts. The top of the first discharge slide is connected to the first discharge port, and the top of the second discharge slide is connected to the second discharge port. Both the first and second discharge slides adopt a U-shaped trough structure. This U-shaped design not only effectively prevents material leakage but also reduces resistance during material conveying, ensuring smooth material conveying.

[0039] A mixing outlet is provided on the mobile frame below the material hopper to discharge the mixed material from the two storage chambers. Simultaneously, a third discharge chute, also a U-shaped chute, is installed on the mobile frame at the positions corresponding to the first and second discharge outlets. This third discharge chute guides the material from the first and second discharge outlets to the mixing outlet, achieving the mixed conveying of the two materials.

[0040] (III) Installation of Drive and Guiding Devices

[0041] Drive wheel sets are installed at the four corners of the bottom of the mobile frame, with each set equipped with a drive motor, specifically a 2.2KW motor as the power source. The drive motors are directly mounted inside the wheel hubs, rotating the wheels to move the mobile frame around the high-speed rail construction site. The drive motors offer advantages such as small size, high power density, and precise control, allowing for flexible adjustment of the equipment's speed and direction according to construction needs.

[0042] A guide wheel assembly is installed at the bottom of the mobile frame. This assembly includes an adjusting arm, a guide wheel frame, and guide wheels. The adjusting arm is slidably mounted on the mobile frame, and the guide wheel frame is fixedly installed at its bottom. Guide wheels rotatably mount on the guide wheel frame, and these guide wheels roll in contact with the side of the high-speed rail track. A telescopic adjuster is installed on the mobile frame, with one end hinged to the guide wheel frame and the other end hinged to the mobile frame. The telescopic adjustment allows for adjustment of the contact pressure between the guide wheels and the side of the high-speed rail track, ensuring the concrete placing machine moves stably along the track and preventing deviation.

[0043] II. Equipment Workflow

[0044] (I) Material Storage and Transportation

[0045] Two different concrete materials are poured into two storage chambers through the top opening of the placing hopper. When a specific material needs to be transported separately, the valve of the first or second discharge port of the corresponding storage chamber is opened, and the material is transported to the designated pouring position by gravity through the first or second discharge chute.

[0046] (II) Material Mixing and Conveying

[0047] When two materials need to be mixed, the first and second discharge valves are opened simultaneously. The materials enter the third discharge chute through the first and second discharge chutes, respectively. After initial mixing in the third discharge chute, the materials are discharged through the mixing outlet. To further ensure uniform mixing, a vibrator is installed on the moving frame below the material hopper. During the material mixing and conveying process, the vibrator is activated to ensure thorough mixing of the materials at the mixing outlet, guaranteeing the uniformity and quality of the concrete.

[0048] (III) Equipment Movement and Positioning

[0049] Depending on the different pouring locations required for high-speed rail construction, the drive motor is started to move the mobile frame. During the movement, the guide wheel assembly plays its role, with the guide wheels in close contact with the side of the high-speed rail track. The position of the guide wheels is adjusted in real time via the telescopic adjuster to ensure the concrete placing boom moves stably along the track. Once the designated pouring location is reached, the motor is stopped, the equipment is secured, and the concrete placing operation begins.

[0050] (iv) Adjustment of the length of the discharge chute

[0051] When encountering different pouring ranges or construction scenarios, the lengths of the first and second discharge chutes can be adjusted according to actual needs. By using the lifting bolt holes along the length of the first and second discharge chutes, bolts can be used to connect chute segments of different lengths, achieving flexible adjustment of the chute length to meet diverse construction requirements.

[0052] Through the above specific implementation methods, this high-speed railway concrete placing machine can efficiently and flexibly complete concrete placing operations, meet the complex and ever-changing construction requirements in high-speed railway construction, improve construction efficiency and quality, and reduce construction costs.

[0053] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
