Description

Technical Field

[0001] This utility model relates to the field of underground continuous wall construction equipment, and in particular to a TPD construction method machine and its sliding rail system. Background Technology

[0002] In the field of diaphragm wall construction, the TPD (Trenching Pile Diaphragm) machine is a core piece of equipment, specifically designed for high-precision, high-efficiency diaphragm wall construction. This equipment mainly consists of four parts: a chassis system, a frame, a gantry system, and a cutter assembly. The chassis system provides overall support and mobility, typically equipped with tracks or wheels to adapt to complex terrain. The frame, mounted on the chassis system, serves as the main framework of the equipment, bearing the load of the gantry system and the cutter assembly. The gantry system, fixed to the frame, guides the vertical lifting and lowering movement of the cutter assembly, ensuring the accuracy of trenching operations. The cutter assembly, guided by the gantry system, cuts and trenches the diaphragm wall; its movement stability directly determines the construction quality.

[0003] In actual construction, the chassis needs to be connected to the track frame (or traveling mechanism) via the chassis system, allowing for forward and backward sliding adjustment of the chassis relative to the chassis system to accommodate the cutting and grooving of continuous walls. However, the existing slide rail system of TPD (Transmission of Diaphragm) construction machines has the following technical drawbacks:

[0004] The complex structure and low maintenance efficiency of traditional slide rail systems mean that the guide rails and guide seats are mostly welded or integrated, which makes the connection structure between the frame and chassis system cumbersome to disassemble and assemble. Especially in narrow construction environments, maintenance is time-consuming and depends on professional personnel, which seriously affects the continuity of construction.

[0005] Insufficient impact resistance and wear resistance; harsh construction environment for diaphragm walls; mud, sand and gravel easily infiltrate the contact surface of the guide rail; and the lubrication structure of existing guide rail systems is mostly a closed design, which cannot quickly flush out contaminants or replenish lubricating oil, resulting in accelerated wear of the contact surface between the guide rail and the guide seat and reduced service life.

[0006] The traditional slide rail system has poor stroke adjustment flexibility, and the frame position needs to be frequently adjusted during construction to match different trench depths or geological conditions. However, the guide rail length of the traditional slide rail system is fixed and lacks modular expansion capability, making it difficult to adapt to changing working conditions.

[0007] Furthermore, existing sliding rail systems often employ simple bolt fixing or baffle limiting structures, which are prone to limiting failure under frequent starts and stops and impact loads, leading to uncontrolled relative sliding between the frame and chassis system. To address these issues, there is an urgent need for a highly reliable, easy-to-maintain, wear-resistant, and adjustable-stroke sliding rail system to meet the stringent requirements of TPD (Transient Damping) construction machines in diaphragm wall construction.

[0008] This invention addresses the unique working conditions and functional requirements of TPD (Transmission Method) machines by proposing an innovative slide rail system. Through optimized design of the guide rail assembly and guide seat, the introduction of an open lubrication structure, and a modular expansion scheme, it significantly improves the operating efficiency and safety of the equipment in complex environments. Existing technologies urgently need improvement to address the aforementioned issues. Summary of the Invention

[0009] To address the aforementioned problems, the present invention aims to provide a TPD (Transformation and Diagnostics) machine and its slide rail system, which has the advantages of simple structure, high maintenance efficiency, strong impact and wear resistance, and flexible stroke adjustment.

[0010] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] This application provides a slide rail system, the technical solution of which is as follows: A slide rail system includes a guide rail assembly and a guide seat. The guide rail assembly includes a guide rail linearly arranged along its length direction, and a linear groove arranged along its length direction is constructed on the guide rail. A sliding groove is provided inside the guide seat, and a limiting plate is detachably connected to the groove opening. The guide rail in the guide rail assembly is embedded in the sliding groove of the guide seat, and the limiting plate is engaged in the linear groove of the guide rail; when the guide rail assembly and the guide seat slide relative to each other, the limiting plate slides relative to the linear groove, and the limiting plate prevents the guide rail from disengaging from the sliding groove.

[0012] Furthermore, this application also proposes that the width of the guide rail is adapted to the width of the guide seat's groove.

[0013] Furthermore, this application also proposes that a through hole is constructed on the side wall of the guide seat, and a fastener passes through the through hole to fix the limiting plate to the inner side wall of the slide groove.

[0014] Furthermore, this application also proposes that an oil groove is provided on the bottom surface of the guide seat's slide, and the oil groove is connected to a grease hole for lubricating the contact surface between the guide rail and the guide seat.

[0015] Furthermore, this application also proposes that the guide rail assembly further includes a guide rail base and an end plate; the guide rail base is fixedly connected to the guide rail, and the end plate is fixedly connected to both ends of the guide rail base and the guide rail; the linear slot is directly constructed on the guide rail, or formed by the connection structure between the guide rail and the guide rail base.

[0016] Furthermore, this application also proposes that the cross-section of the guide rail is L-shaped, and when it is fixed to the guide rail seat, a linear groove is formed between the L-shaped guide rail and the guide rail seat.

[0017] Furthermore, this application proposes that the upper end of the guide rail seat is provided with a mounting groove, and one end of the guide rail is embedded in the mounting groove and fixed by a screw fastener. Furthermore, this application also proposes that the guide seat has an open structure, allowing direct flushing of mud and sand inside the chute and rapid replenishment of lubricating oil.

[0018] Furthermore, this application also proposes a TPD (Transmission Method) machine, including the aforementioned slide rail system; a guide seat is fixedly connected to the track frame, and the guide rail assembly is fixedly connected to the lower end of the frame; the frame is adjusted to slide back and forth relative to the track frame based on the slide rail system.

[0019] As can be seen from the above, the slide rail system and TPD construction machine provided in this application significantly improve the operating efficiency and safety of the equipment in complex environments by optimizing the matching design of the guide rail assembly and guide seat, introducing an open lubrication structure and a modular expansion scheme. It has the advantages of simple structure, high maintenance efficiency, strong impact resistance and wear resistance, and flexible stroke adjustment. Attached Figure Description

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

Therefore, they should not be construed as limitations on this utility model.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more, unless otherwise expressly defined.

[0026] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., 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.

[0028] Example 1:

[0029] like Figure 1 and 2 As shown, this embodiment relates to a slide rail system, including a guide rail assembly and a guide seat 4. The guide rail assembly includes a guide rail 2 linearly arranged along its length, and a linear groove 7 arranged along its length is formed on the guide rail 2. A sliding groove 8 is provided inside the guide seat 4, and a limiting plate 3 is detachably connected to the groove opening of the sliding groove 8. The guide rail 2 in the guide rail assembly is embedded in the sliding groove 8 of the guide seat 4, and the limiting plate 3 is engaged in the linear groove 7 of the guide rail 2. When the guide rail assembly slides relative to the guide seat 4, the limiting plate 3 slides relative to the linear groove 7, and the limiting plate 3 restricts the guide rail 2 from disengaging from the sliding groove 8. The limiting plate 3 can be fixed in the groove opening of the sliding groove 8 by bolts, clips, or other detachable connection methods. Furthermore, the shape and size of the limiting plate 3 can be adjusted according to the linear groove 7 of the guide rail 2 to ensure that it can effectively restrict the disengagement of the guide rail 2.

[0030] Specifically, when the guide rail assembly slides relative to the guide seat 4, the cooperation between the limiting plate 3 and the linear groove 7 effectively prevents the guide rail 2 from detaching from the slide groove 8. This design ensures the stability of the slide rail system during operation, preventing equipment malfunctions caused by the guide rail 2 detaching. Furthermore, since the limiting plate 3 is detachably connected to the groove opening of the slide groove 8, it can be quickly removed for maintenance or replacement, facilitating operation. As a preferred embodiment, the limiting plate 3 can be made of wear-resistant material to extend its service life. Simultaneously, the groove opening of the slide groove 8 can be designed as an open structure, offering strong adaptability. In harsh muddy and sandy conditions, the fully open structure allows direct washing of the guide seat 4 and guide rail 2, facilitating cleaning and lubrication, thereby further improving the maintenance efficiency of the slide rail system. Therefore, the technical solution of this application solves the technical problem of the guide rail 2 easily detaching from the slide groove 8 in the slide rail system by optimizing the cooperation design between the guide rail assembly and the guide seat 4. Compared with existing technologies, this solution has the advantages of simple structure, convenient maintenance, and stable operation, and can effectively improve the reliability and service life of the slide rail system.

[0031] Furthermore, the width of the guide rail 2 is adapted to the width of the groove 8 of the guide seat 4. Specifically, the width of the guide rail 2 can be precisely designed according to the width of the groove 8 of the guide seat 4 to ensure that the guide rail 2 can smoothly fit into the groove 8. As a preferred embodiment, the width of the guide rail 2 can be slightly smaller than the width of the groove 8 to allow for a certain gap during sliding, thereby reducing frictional resistance. In addition, the width of the guide rail 2 can also be matched by adjusting the width of the groove 8 of the guide seat 4, for example, by fine-tuning the width of the groove 8 using an adjustable limiting plate 3 or a shim to accommodate guide rails 2 of different sizes. By designing the width of the guide rail 2 to match the width of the groove 8 of the guide seat 4, it is ensured that the guide rail 2 can smoothly fit into the groove 8 and remain stable during sliding. This design avoids increased sliding resistance or jamming caused by width mismatch, thereby improving the operating efficiency and reliability of the slide rail system. Compared with existing technologies, this technical solution effectively solves the problem of uneven sliding by precisely matching the width of the guide rail 2 and the slide groove 8, ensuring the stability and durability of the slide rail system in practical applications.

[0032] exist Figure 1In the illustrated scheme, a through hole 9 is constructed on the side wall of the guide seat 4. Fasteners pass through the through hole 9 to fix the limiting plate 3 to the inner side wall of the slide groove 8. The position of the through hole 9 can be adjusted according to the size and shape of the limiting plate 3 to ensure that the fasteners can effectively fix the limiting plate 3. The fastener can be a bolt, screw, or other suitable fixing device, the specific choice depending on the actual application scenario and the required fixing strength. Furthermore, the number and distribution of the through holes 9 can also be optimized according to the stress condition of the limiting plate 3 to enhance the fixing effect. Specifically, the design of the through holes 9 can include multiple holes to allow for multi-point fixing at different locations on the limiting plate 3, thereby improving the stability of the overall structure. As a preferred embodiment, the through holes 9 can be set symmetrically on the side wall of the guide seat 4 to ensure uniform stress on the limiting plate 3 and avoid stress concentration problems caused by single-point fixing. Further, after the fastener passes through the through hole 9, it can be fixed by a nut or other locking device to prevent the fastener from loosening under vibration or impact. Therefore, through the cooperation of the through hole 9 on the side wall of the guide seat 4 and the fastener, the limiting plate 3 is more firmly fixed in the slide groove 8, avoiding loosening or falling off the limiting plate 3 due to sliding or impact. This design not only improves the stability and reliability of the slide rail system, but also allows for direct control of the installation and removal of the limiting plate 3 through the screw fasteners on the outside of the guide seat 4, making the installation and removal of the limiting plate 3 more convenient, and thus making the entire slide rail system easier to assemble and disassemble. Compared with the prior art, this technical solution effectively solves the technical problem of the limiting plate 3 not being firmly fixed through simple structural improvements, and has high practicality and promotional value.

[0033] The bottom surface of the guide seat 4's slide groove 8 is provided with an oil groove, which communicates with a grease hole for lubricating the contact surface between the guide rail 2 and the guide seat 4. The oil groove can be designed as a straight line, wave, spiral, or figure-seven, with the specific shape selected according to lubrication requirements. As a preferred embodiment, the depth and width of the oil groove can be optimized according to the viscosity and flow rate of the lubricating oil to ensure that the lubricating oil is evenly distributed on the contact surface. Furthermore, the grease hole can be located on the side or bottom of the slide groove 8, with the specific location selected based on the actual installation space and lubrication effect. For example, the grease hole can be located at the bottom of the slide groove 8 and connected to an external lubrication system via a pipe to achieve automatic lubrication. This technical solution, through the communication design between the oil groove and the grease hole, allows lubricating oil to flow into the oil groove through the grease hole, thereby evenly distributing it on the contact surface between the guide rail 2 and the guide seat 4. Thus, the lubricating oil can effectively reduce friction between the guide rail 2 and the guide seat 4, preventing wear on the contact surface due to insufficient lubrication, thereby extending the service life of the slide rail system. Compared with existing technologies, this technical solution has the advantages of simple structure, significant lubrication effect and convenient maintenance. It can effectively solve the technical problem of insufficient lubrication during the sliding process of the slide rail system, which leads to wear on the contact surface between the guide rail 2 and the guide seat 4.

[0034] like Figure 1 and 2 As shown, the guide rail assembly also includes a guide rail seat 1 and an end plate 5; the guide rail seat 1 is fixedly connected to the guide rail 2, and the end plate 5 is fixedly connected to both ends of the guide rail seat 1 and the guide rail 2; the linear groove 7 is directly constructed on the guide rail 2, or formed by the connection structure between the guide rail 2 and the guide rail seat 1. The fixed connection between the guide rail seat 1 and the guide rail 2 can be achieved by welding, bolting, or snap-fit ​​connection. The end plate 5 can be fixed to both ends of the guide rail seat 1 and the guide rail 2 by welding, bolting, or snap-fit ​​connection. The linear groove 7 can be directly machined on the guide rail 2, for example by milling, stamping, or casting; or it can be formed by the connection structure between the guide rail 2 and the guide rail seat 1, for example, the gap between the guide rail seat 1 and the guide rail 2 or the protrusion on the guide rail seat 1 cooperating with the groove on the guide rail 2 to form the linear groove 7. Specifically, the fixing method between guide rail seat 1 and guide rail 2 can be selected according to actual needs. Welding is suitable for applications requiring high-strength connections, bolt connections are suitable for applications requiring disassembly and maintenance, and snap-fit ​​connections are suitable for applications requiring quick installation. The end plate 5 enhances the connection strength between guide rail 2 and guide rail seat 1, preventing guide rail 2 from shifting or falling off during sliding. The construction method of linear slot 7 can be selected according to the material and processing technology of guide rail 2. Directly constructing it on guide rail 2 simplifies the processing flow and improves production efficiency; forming it through the connection structure between guide rail 2 and guide rail seat 1 increases the flexibility of linear slot 7, adapting to different sliding requirements. Therefore, this application simplifies the connection structure between guide rail 2 and guide rail seat 1 by introducing guide rail seat 1 and end plate 5. The fixing of guide rail seat 1 and guide rail 2 and the setting of end plate 5 allow linear slot 7 to be directly constructed on guide rail 2 or formed through the connection structure between guide rail 2 and guide rail seat 1. This design improves the flexibility of constructing the linear slot 7, simplifies the overall structure of the slide rail system, and solves the problems of complex connection structures and inflexible construction of the linear slot 7 in traditional slide rail systems. Compared with the prior art, the technical solution of this application has the advantages of simple structure, convenient installation, and easy maintenance, and can effectively improve the efficiency and reliability of the slide rail system.

[0035] In a more specific implementation, the guide rail 2 has an L-shaped cross-section. When it is fixed to the guide rail seat 1, a linear groove 7 is formed between the L-shaped guide rail 2 and the guide rail seat 1. Specifically, the L-shaped cross-section design of the guide rail 2 allows the linear groove 7 to be naturally formed between the guide rail 2 and the guide rail seat 1. This design simplifies the construction process of the linear groove 7 and improves assembly efficiency. The cooperation between the L-shaped guide rail 2 and the guide rail seat 1 not only ensures the precise formation of the linear groove 7 but also enhances the overall stability and durability of the guide rail system. Through this structure, the connection between the guide rail 2 and the guide rail seat 1 is more secure, reducing the risk of loosening or detachment due to vibration or impact.

[0036] In a preferred embodiment, the cross-section of the L-shaped guide rail 2 can be manufactured using cold bending or extrusion forming processes to ensure its geometric accuracy and strength. Furthermore, the material of the guide rail base 1 can be high-strength alloy steel or wear-resistant material to enhance its impact and wear resistance. Thus, the technical solution of this application solves the technical problem of forming a linear groove 7 between the guide rail 2 and the guide rail base 1 through the cooperation of the L-shaped guide rail 2 and the guide rail base 1. Compared with the prior art, this solution not only simplifies the construction process of the linear groove 7 but also improves assembly efficiency and the overall stability of the system. With this structure, the connection between the guide rail 2 and the guide rail base 1 is more robust, reducing the risk of loosening or separation due to vibration or impact, thereby improving the reliability and service life of the slide rail system.

[0037] Furthermore, the upper end of the guide rail base 1 is provided with a mounting groove 6, and one end of the guide rail 2 is embedded in the mounting groove 6 and fixed by a screw fastener. The design of the mounting groove 6 allows the guide rail 2 to be firmly embedded in the guide rail base 1, avoiding the inconvenience of disassembly and assembly caused by traditional welding or integrated designs. The use of the screw fastener further enhances the connection's firmness, ensuring a stable connection between the guide rail 2 and the guide rail base 1, simplifying the disassembly and assembly process, and improving maintenance efficiency. Specifically, the shape and size of the mounting groove 6 can be designed according to the cross-sectional shape of the guide rail 2. For example, the groove can be rectangular, trapezoidal, or other suitable shapes to ensure that the guide rail 2 can be tightly embedded. The screw fastener can be a bolt, screw, or other fastener, which fixes the guide rail 2 in the mounting groove 6 through threaded connection or snap-fit. As a preferred embodiment, the screw fastener can adopt an anti-loosening design to prevent loosening under vibration or impact. Thus, this technical solution, through the combination of the mounting groove 6 and the screw fastener, effectively solves the technical problems of weak connection and inconvenient disassembly and assembly between the guide rail 2 and the guide rail base 1. Compared with existing technologies, this solution not only improves the stability and reliability of the connection but also simplifies the assembly and disassembly process, reducing maintenance costs and time. Specifically, the design of the mounting groove 6 allows the guide rail 2 to be quickly inserted and removed, while the use of screw fasteners ensures the robustness of the connection, avoiding the inconveniences of traditional welding or integrated designs. Therefore, this technical solution has significant practicality and economic advantages in real-world applications.

[0038] Furthermore, the guide seat 4 features an open structure, allowing direct flushing of mud and sand inside the chute 8 and rapid replenishment of lubricating oil. This open design allows the top or sides of the chute 8 to be partially open, facilitating direct entry of external media for flushing. Through this design, contaminants such as mud and sand inside the chute 8 can be directly flushed away, effectively removing impurities and facilitating rapid replenishment of lubricating oil, ensuring effective lubrication between the guide rail 2 and the guide seat 4. This open structure solves the problem of difficult maintenance of traditional enclosed slide rail systems in harsh environments, improving the durability and maintenance efficiency of the slide rail system. Compared with existing technologies, this solution not only simplifies the maintenance process of the slide rail system but also significantly improves the reliability and service life of the system in complex environments.

[0039] The installation sequence of the slide rail system described in the above scheme is as follows: First, the guide rail seat 1 is installed on the upper fixed seat (i.e., the frame 12 described in Embodiment 2), and the guide seat 4 is connected to the lower fixed seat (i.e., the track frame 11 described in Embodiment 2); then, the guide rail 2 is installed on the guide rail seat 1 and falls into the slide groove 8 of the guide seat 4; after adjustment, the limiting plate 3 is installed in the groove of the slide groove 8 of the guide seat 4; finally, the end plate 5 is installed on both ends of the guide rail 2.

[0040] Example 2:

[0041] like Figure 3 As shown, this embodiment relates to a TPD (Transmission Method) machine, including the slide rail system described in Embodiment 1. The guide seat 4 is fixedly connected to the track frame 11, and the guide rail assembly is fixedly connected to the lower end of the frame 12; the frame 12 is adjusted to slide back and forth relative to the track frame 11 based on the slide rail system.

[0042] Therefore, this application achieves forward and backward sliding adjustment of the vehicle frame 12 relative to the track frame 11 by fixing the guide seat 4 of the slide rail system to the track frame 11 and the guide rail assembly to the lower end of the vehicle frame 12. This design utilizes the linear sliding characteristics of the slide rail system, allowing the vehicle frame 12 to be adjusted in position as needed during construction, thereby adapting to different construction conditions and requirements. Through this structure, the TPD method machine can more flexibly construct diaphragm walls, improving construction efficiency and accuracy. Compared with existing technologies, the slide rail system of this application has advantages such as simple structure, convenient maintenance, strong impact and wear resistance, and flexible stroke adjustment, effectively solving the technical pain points of traditional slide rail systems in complex construction environments.
