Description

Technical Field

[0001] This utility model relates to the field of engineering machinery, specifically to a chassis system and a TPD (Transformation Method for Diagnostics) machine. Background Technology

[0002] With the acceleration of urbanization and the increasing demand for underground space development, diaphragm wall construction technology has been widely applied. As an important piece of equipment for diaphragm wall construction, the TPD (Diverterless Damping) machine plays a vital role in urban underground space development and infrastructure construction. The TPD machine mainly consists of a chassis system, frame, gantry system, and cutterhead assembly. Among these, the chassis system, as the basic support structure of the entire machine, has a decisive impact on the stability, mobility, and construction efficiency of the equipment.

[0003] Currently, most TPD (Transformer Method) machine chassis systems on the market adopt a tracked structure, such as the "tracked TPD machine with an electric motor-hydraulic tracked chassis" disclosed in CN222120371U. This machine includes a tracked chassis, a power unit, and a cutting box assembly. It moves by driving an electric motor-hydraulic pump, which in turn drives a hydraulic motor, thereby moving the TPD machine through the transmission tracks. This electric motor-hydraulic drive method, to some extent, solves the problems of noise, air pollution, and low efficiency inherent in traditional equipment.

[0004] Regarding tracked chassis structure design, CN203795503U discloses "a reinforced excavator chassis," which includes a lower frame with track frames on both sides. One end of each track frame has a motor mount, and the other end has a guide wheel mount. Track rollers are located on the bottom surface of the track frames, ensuring more stable and reliable track movement. Similarly, CN212890649U discloses "a reinforced tracked chassis assembly suitable for large-tonnage mobile crushers," which employs a welded connection structure, avoiding the problem of loosening connecting bolts due to vibration and improving structural stability.

[0005] To adapt to different working conditions, CN218929626U discloses "a telescopic tracked chassis," which effectively solves the problems of non-adjustable width, low roadway adaptability, and easy tipping of narrow-body tracked chassis by adjusting the distance between the track frames using telescopic cylinders. CN112572626B proposes "a triangular tracked hydraulic direct-drive contour-following chassis and its contour-following method," which improves the terrain adaptability of the equipment through a contour-following suspension mechanism.

[0006] However, the existing TPD method machine chassis system still has the following technical problems:

[0007] 1. In the traditional TPD (Transmission Method) machine's tracked chassis design, the slide rail assembly is typically positioned between the two tracks. This layout forces an increase in the distance between the tracks, resulting in an excessively wide chassis system. In confined urban construction spaces or underground environments, the equipment's mobility and applicability are severely limited, making it difficult to meet the construction needs in complex environments.

[0008] 2. Because the slide rail assembly occupies the core area between the tracks, the installation space of the equipment working system (such as the chain cutter assembly) is greatly compressed, making it difficult to operate the equipment during installation, disassembly and maintenance. This not only increases the difficulty of construction, but also prolongs the maintenance time, affecting the progress of the project and the efficiency of construction.

[0009] Therefore, there is an urgent need to develop a new type of TPD construction method machine chassis system, optimize the layout of the slide rail components, rationally plan the equipment's working area, improve the equipment's adaptability and working efficiency in narrow spaces, and ensure that the structure is stable and reliable to meet the actual needs of modern underground engineering construction. Summary of the Invention

[0010] To address the technical problems of excessively wide chassis, limited mobility due to the tracked walking mechanism of traditional TPD construction method machines, and restricted installation and maintenance space for the working system, a chassis system for TPD construction method machines is provided. This system enables the equipment to adapt to special terrains with narrow roads, improves the stability of the mechanism, and increases the internal operating space.

[0011] The technical solution adopted by this utility model to solve its technical problem is as follows: a chassis system for a TPD (Transformer Method) machine is provided, including two sets of symmetrically arranged walking components and a connecting beam connecting the two sets of walking components; each set of walking components includes a track frame, a track mounted on the track frame and a hydraulic motor, wherein the hydraulic motor drives the track to rotate cyclically on the track frame; a mounting seat is fixedly connected to the outer side of the track frame, the mounting seat extends beyond the outer edge of the track to form a mounting surface for mounting a slide rail assembly.

[0012] Furthermore, the hydraulic motor is symmetrically arranged at the rear end of the track frame to provide power output; the traveling assembly also includes a guide wheel, installed at the front end of the track frame to tension the track; the traveling assembly also includes a support roller, arranged along the length of the track frame to support the track and maintain uniform force; the track surrounds the guide wheel, support roller and the drive wheel of the hydraulic motor to form a closed traveling structure.

[0013] Furthermore, the mounting base is integrally formed with the outer wall of the track frame, which improves the structural strength and stability.

[0014] Furthermore, there are multiple mounting seats, which are spaced apart on the outer side wall of the track frame, and the mounting surfaces of the multiple mounting seats are flush to ensure that the slide rail assembly is installed stably.

[0015] Furthermore, the connecting beam is provided with first flanges at both ends, and a connecting seat is integrally provided on the inner end of the track frame, and a second flange is provided on the connecting seat; the first flange and the second flange are fixed together by multiple sets of bolting assemblies to achieve a reliable connection between the connecting beam and the track frame.

[0016] Furthermore, the upper end of the connecting beam is provided with lifting lugs for performing hoisting operations, facilitating the transportation and installation of the equipment.

[0017] Furthermore, at least two connecting beams are provided, and the front end of the track frame and the foremost connecting beam enclose a working area for the installation of the chain cutter assembly, providing ample operating space for the working system.

[0018] This utility model also provides a TPD (Transformer-Doped Diameter) machine, including the aforementioned chassis system; a frame mounted on the chassis system; a gantry system mounted on the frame; and a chain cutter assembly that is lifted and lowered on the gantry system. The frame is mounted on a mounting base of the chassis system via a slide rail assembly, and the chain cutter assembly is located in the working area of ​​the equipment.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. By placing the mounting base on the outer side of the track frame and extending it beyond the outer edge of the track, the slide rail assembly is installed on the outside of the track instead of between the two tracks in the traditional way. This effectively reduces the distance between the two tracks, making the chassis narrower and more adaptable to special terrains with narrow roads. It also improves the mobility and applicability of the equipment in narrow construction spaces.

[0021] 2. The integrated support frame structure is adopted, and the slide rail system is installed on the outside, which disperses the load, improves the overall stability and torque resistance of the mechanism, and makes the equipment more stable and reliable during operation.

[0022] 3. The mounting bases are distributed on both sides, which makes the overall internal operating space larger, providing ample space for the installation, disassembly and maintenance of the equipment working system, reducing construction difficulty and improving project efficiency.

[0023] 4. The front of the base has an open structure, with a space margin of 1 / 3 of the overall base. The cutting box is placed on the front side, which makes it easy to observe the operating status and working condition of the cutter. It also facilitates the installation of the cutter box and the handling of emergencies during the working process, such as replacing damaged cutters or changing special cutter teeth, thereby improving the maintainability and working efficiency of the equipment.

[0024] 5. The tracks on both sides are located on both sides of the groove, which can better balance the pressure and improve the overall stability and working accuracy of the equipment. Attached Figure Description

[0033] Example 1:

[0034] like Figure 1 and 2 As shown, this embodiment relates to a chassis system for a TPD (Transient Damping) machine, including two symmetrically arranged traveling components and a connecting beam 1 connecting the two traveling components. Each traveling component includes a track frame 3, a track 5 mounted on the track frame 3, and a hydraulic motor 2. The hydraulic motor 2 drives the track 5 to rotate cyclically on the track frame 3. A mounting seat 7 is fixed to the outer side of the track frame 3, extending beyond the outer edge of the track 5 to form a mounting surface for mounting a slide rail assembly. In this design, the hydraulic motor 2 is symmetrically arranged at the rear end of the track frame 3 to provide power output. The traveling component also includes guide wheels 6, mounted at the front end of the track frame 3, for tensioning the track 5. The traveling component also includes support rollers 4, arranged along the length of the track frame 3, for supporting the track 5 and maintaining uniform force. The track 5 surrounds the guide wheels 6, support rollers 4, and the drive wheel of the hydraulic motor 2, forming a closed traveling structure.

[0035] Mounting base 7 is integrally formed with the outer side wall of track frame 3. There are multiple mounting bases 7, which are spaced apart on the outer side wall of track frame 3, and the mounting surfaces of the multiple mounting bases 7 are flush.

[0036] The connecting beam 1 has first flanges 9 at both ends, and a connecting seat 10 is integrally provided on the inner end of the track frame 3. A second flange 11 is provided on the connecting seat 10. The first flanges 9 and the second flanges 11 are fixed together by multiple sets of bolt assemblies. The upper end of the connecting beam 1 is provided with lifting lugs 13 for lifting operations.

[0037] At least two connecting beams 1 are provided, and the front end of the track frame 3 and the foremost connecting beam 1 enclose the equipment working area 15 for the installation of the chain cutter assembly 14.

[0038] The chassis system of the TPD method machine in this embodiment features structural stability and strong load-bearing capacity. It achieves good balance and stability through two symmetrically arranged walking components. The walking components adopt a tracked design, enhancing the equipment's adaptability and maneuverability in complex terrain. The two walking components are firmly connected by connecting beam 1, forming an integral frame structure. Connecting beam 1 is made of high-strength steel and can withstand large working loads. Both ends of connecting beam 1 are connected to the connecting seats 10 of the track frame 3 via flanges 9, and are secured with multiple sets of bolts to ensure the reliability and stability of the connection.

[0039] The track frame 3, as the main frame of the traveling assembly, adopts an integral structural design, possessing sufficient strength and rigidity. A mounting base 7 is fixedly connected to the outer side of the track frame 3, extending beyond the outer edge of the track 5 to form a mounting surface for the slide rail assembly. This design allows the slide rail assembly to be installed on the outside of the track 5 without interfering with its normal operation, while also facilitating the installation and adjustment of the chassis 16.

[0040] The mounting base 7 is integrally formed with the outer wall of the track frame 3, which enhances the structural strength and avoids stress concentration problems that may be caused by welding. There are multiple mounting bases 7, which are spaced apart on the outer wall of the track frame 3, and the mounting surfaces of the multiple mounting bases 7 are flush, ensuring that the slide rail assembly is installed stably and runs smoothly.

[0041] Hydraulic motors 2 are symmetrically positioned at the rear end of the track frame 3, driving the tracks 5 to rotate via drive wheels, thus providing power to the entire chassis system. Hydraulic motors 2 employ a high-efficiency, high-torque hydraulic drive device, capable of meeting the power requirements of the TPD (Transformer for Pulsing) machine under various working conditions.

[0042] The idler wheel 6 is installed at the front end of the track frame 3, mainly serving to guide and tension the track 5. The idler wheel 6 is made of wear-resistant material, possessing good wear resistance and service life. The idler wheel 6 is connected to the track frame 3 via a tensioning mechanism, allowing adjustment of the track 5's tension to ensure it maintains appropriate tension during operation.

[0043] Track rollers 4 are arranged along the length of the track frame 3 to support the track 5 and maintain uniform force. The number and spacing of track rollers 4 are determined according to the length of the track 5 and the expected load capacity, typically 5-8 on each side. Track rollers 4 are made of high-strength alloy material, possessing good load-bearing capacity and wear resistance.

[0044] Track 5 surrounds the idler wheel 6, track roller 4, and drive wheel of hydraulic motor 2, forming a closed walking structure. Track 5 adopts a metal link structure, which has high strength and wear resistance, and can adapt to various complex working environments. The surface of track 5 is equipped with anti-slip patterns, which enhances the traction and stability of the chassis system.

[0045] A lifting lug 13 is provided at the upper end of the connecting beam 1 for lifting operations. The lifting lug 13 is made of high-strength steel and undergoes a special heat treatment process, giving it high strength and toughness, capable of withstanding the overall lifting weight of the equipment. The design of the lifting lug 13 complies with relevant safety standards, ensuring the safety and reliability of the lifting process.

[0046] At least two connecting beams 1 are provided. The front end of the track frame 3 and the foremost connecting beam 1 enclose a working area 15 for the installation of the chain cutter assembly 14. Figure 1 The dotted area in the diagram. This design allows the chain cutter assembly 14 to be mounted at the front of the chassis system, facilitating construction operations. The dimensions of the equipment's working area 15 are determined based on the size of the chain cutter assembly 14 and the operational requirements.

[0047] In practical applications, the TPD construction machine chassis system of this embodiment can be appropriately adjusted and optimized according to engineering requirements. For example, different materials and patterns of tracks 5 can be selected according to different working environments; the number and distribution of support rollers 4 can be adjusted according to load requirements; and hydraulic motors 2 with different power can be selected according to power requirements, etc.

[0048] Example 2:

[0049] like Figure 3 As shown, this embodiment relates to a TPD (Transformer-Doped Diameter) machine, including a chassis system as described in Embodiment 1; a frame 16 mounted on the chassis system; a gantry system 17 mounted on the frame 16; and a chain cutter assembly 14 mounted on the gantry system 17. The frame 16 is mounted on the mounting base 7 of the chassis system via a slide rail assembly, and the chain cutter assembly 14 is located in the working area 15 of the equipment.

[0050] The TPD construction method machine of this embodiment is an engineering machinery equipment specifically designed for diaphragm wall construction. It mainly consists of four parts: a chassis system, a frame 16, a gantry system 17, and a cutterhead assembly 14. The chassis system provides support and mobility for the entire equipment. The frame 16 is mounted on the chassis system, the gantry system 17 is mounted on the frame 16, and the cutterhead assembly 14 is mounted on the gantry system 17, allowing for lifting and lowering under the guidance of the gantry system 17. The chassis system adopts the structure described in Embodiment 1, including two symmetrically arranged walking components and a connecting beam 1 connecting the two walking components. The walking components adopt a tracked design, enhancing the equipment's adaptability and passability in complex terrain. A mounting seat 7 is fixed to the outer side of the track frame 3, extending beyond the outer edge of the track 5 to form a mounting surface for mounting the slide rail assembly. The frame 16 is mounted on the chassis system and connected to the mounting seat 7 of the chassis system via the slide rail assembly. The slide rail assembly includes a slide rail fixed to the mounting base 7 and a slider mounted on the bottom of the frame 16. The slider can slide on the slide rail, enabling the frame 16 to move back and forth relative to the chassis system. This design allows the TPD method machine to adjust the position of the cutter chain assembly 14 according to construction needs, increasing the flexibility and adaptability of the equipment.

[0051] The chain cutter assembly 14 is mounted on the guide rail of the gantry system 17 and can move up and down under the guidance of the guide rail. The chain cutter assembly 14 mainly consists of a drive unit, a chain, cutters, and a mud circulation system. The drive unit usually uses a high-power motor or hydraulic motor, which drives the chain to rotate through a reducer and transmission mechanism. Multiple cutters are mounted on the chain for cutting the soil. The mud circulation system mixes the cut soil with mud and pumps it out, while simultaneously supplying fresh mud to the cutting surface to maintain its stability.

[0052] The cutterhead assembly 14 is located in the equipment's working area 15, specifically the area enclosed between the front end of the track frame 3 and the foremost connecting beam 1. This design allows the cutterhead assembly 14 to be operated from the front of the chassis system, facilitating observation and control. Simultaneously, the location of the cutterhead assembly 14 between the two tracks 5 increases the equipment's stability and safety. Furthermore, when the cutterhead assembly 14 malfunctions and requires repair (such as replacing damaged cutters or special teeth) or needs to be removed from the soil (e.g., when encountering rocks), the open working area 15 provides greater operating space, and the vehicle can also be withdrawn during operation, making repairs or rescues more convenient.

[0053] In practical applications, the TPD method machine of this embodiment can be appropriately adjusted and optimized according to engineering needs. For example, the height of the gantry system 17 can be adjusted according to the required construction depth; different types of cutting tools can be selected according to soil conditions; and the drive power of the chain cutter assembly 14 can be adjusted according to the required construction efficiency.

[0054] The TPD (Through-Dip Damping) construction machine is suitable for various underground continuous wall construction projects, such as subway stations, underground parking garages, and underground utility tunnels. Compared with traditional grab bucket trenching machines, the TPD machine has advantages such as high construction efficiency, good trenching quality, and strong adaptability, and is particularly suitable for construction in hard soil and rock layers.
