Description

Technical Field

[0001] The invention belongs to the technical field of tracks, and in particular relates to a detachable track and a disassembly and assembly method thereof. Background Art

[0002] In the field of construction engineering, construction tracks must meet comprehensive requirements such as high-strength load-bearing, rapid assembly and disassembly, fatigue resistance, and environmental adaptability. Traditional welding or bolt fixing technologies have problems such as irreversible damage, high maintenance costs, and insufficient vibration resistance. Especially in construction scenarios with frequent adjustments (such as temporary tracks and modular construction platforms), a reusable solution that can adapt to dynamic loads is urgently needed.

[0003] In the existing technology, high-strength bolts are usually used in combination with clamps to fix the rails through pre-tightening force. The elastic pressure plate is driven by bolts to work together with the outer flange to form a flexible clamp. The contact surface between the clamp and the rail is laser-engraved with anti-slip patterns to adapt to different rail types. Grooved embedded parts and detachable fasteners are used. The embedded grooves are fixed synchronously during concrete pouring, and the rail brackets are quickly installed later by sliding support arms.

[0004] Although existing technologies have solved the track connection problem to a certain extent, the following key defects still exist: the bolt-and-clamp connection structure relies on high-precision preload control. If the construction error exceeds 0.2mm, it is easy to cause uneven clamping force, resulting in the risk of bolt loosening or clamp sliding. Welded joints need to be reworked multiple times and the sleeve length needs to be increased to deal with the problem of unqualified welds. At the same time, full-open welding is required during installation to avoid welding slag damaging the seals. The construction complexity is relatively high. Modular pre-buried groove technology has strict requirements on groove processing accuracy (±0.1mm). If the concrete pouring error exceeds the standard, it will cause the track bracket to be unable to align later. Although the elastic clamping structure can compensate for thermal deformation, it is easy to cause rebound coefficient mismatch due to material fatigue or corrosion under long-term dynamic loads, requiring frequent adjustment and maintenance. In addition, some technologies (such as frozen joints) rely on the synergistic effect of high-strength bolts and anti-slip tooth patterns, but are prone to rust in humid or oily environments, reducing friction resistance and accelerating the aging of the connector. Summary of the Invention

[0005] The object of the present invention is to provide a detachable track and a method for assembling and disassembling the track, which solves the problems in the above-mentioned background technology through the specific structural design of the track module, the embedded part module and the connection module.

[0006] In order to solve the above technical problems, the present invention is implemented through the following technical solutions: the present invention is a detachable track, including a track module, the track module is arranged along the extension direction of the slide rail, and the track module is arranged in at least two groups along the extension direction of the slide rail, the track module includes a steel rail and a positioning channel steel, and the steel rail is embedded and installed inside the positioning channel steel; an embedded part module, the embedded part module is arranged along the extension direction of the slide rail, and the embedded part module is arranged one-to-one with the track module, and the track module and the corresponding embedded part module are detachably connected; a connecting module, a docking point is formed between two adjacent track modules, the connecting modules are symmetrically arranged on both sides of the docking point, and the connecting module at the docking point is detachably connected to the track module.

[0007] In this embodiment of the present invention, the embedded part module includes a positioning base and embedded steel bars. The embedded steel bars are fixedly arranged at the bottom of the positioning base, and the embedded steel bars are arranged in a linear array at the bottom of the positioning base. The embedded steel bars are embedded in the concrete foundation.

[0008] In this embodiment of the present invention, the embedded part module also includes an embedded plate and an embedded positioning tube.

[0009] In this embodiment of the present invention, the positioning channel steel is made of U-section profile, the inner cavity width of the positioning channel steel is greater than the width of the rail, and the width difference between the inner cavity of the positioning channel steel and the rail is 0.5-1.0 cm. The rail is precisely fitted into the inner cavity groove of the positioning channel steel to form a non-welded inclusive fixed structure.

[0010] In this embodiment of the present invention, the track module also includes a positioning code plate, which is symmetrically fixed on opposite sides of the positioning channel steel. A bolt installation cavity is provided on the inclined surface of the positioning code plate, and a bolt positioning hole connected to the bolt installation cavity is provided at the bottom of the positioning code plate.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0029] See also Figure 1-6The present invention is a detachable track, comprising a track module, an embedded part module and a connection module; the track module is arranged along the extension direction of the slide rail, and at least two groups of the track modules are arranged along the extension direction of the slide rail, the track module comprises a steel rail 1 and a positioning channel steel 2, and the steel rail 1 is embedded and installed inside the positioning channel steel 2; the embedded part module is arranged along the extension direction of the slide rail, and the embedded part module and the track module are arranged in a one-to-one correspondence, and the track module and the corresponding embedded part module are detachably connected; a docking point is formed between two adjacent track modules, the connection modules are symmetrically arranged on both sides of the docking point, and the connection module at the docking point is detachably connected to the track module; the problem to be solved by the present invention is to design a detachable track for construction , the connection of the connecting module improves the convenience of disassembly and installation of the rail 1, and the lower fixed positioning channel steel 2 increases the stability of the rail. The setting of the code plate can effectively solve the problem of lateral movement of the positioning channel steel 2 during construction, and avoid the rail 1 from taking welding measures to limit the position, reduce welding damage and extend the service life. The track module adopts a combined track structure of the rail 1 and the positioning channel steel 2, and the embedded part module is embedded at the bottom of the positioning channel steel 2. The positioning channel steel 2 and the embedded part module are bolted and fastened together by the detachable code plate. The rail 1 is only embedded in the positioning channel steel 2 to avoid direct welding with the code plate, thereby retaining the integrity of the track body. The modular design supports quick disassembly and assembly, and the embedded part module and the code plate can be reused, which reduces welding damage and extends the service life. It is suitable for working scenarios with frequent adjustments.

[0030] In this embodiment of the invention, Figure 1 and Figure 2 As shown, the embedded part module includes a positioning base 3 and embedded steel bars 4. The embedded steel bars 4 are fixedly arranged at the bottom of the positioning base 3, and the embedded steel bars 4 are arranged in a linear array at the bottom of the positioning base 3. The embedded steel bars 4 are embedded in the concrete foundation, and the positioning base 3 is parallel to the bottom surface of the positioning channel steel 2 to form an axial constraint reference plane.

[0031] In this embodiment of the invention, Figure 1 As shown, the embedded part module also includes an embedded plate 5 and an embedded positioning tube 6. The embedded plate 5 is arranged below the positioning base 3, and the embedded plate 5 is fixedly connected to the corresponding embedded steel bar 4. The embedded positioning tube 6 is fixedly set on the top of the embedded plate 5. The top of the positioning base 3 is provided with a positioning port corresponding to the embedded positioning tube 6 one by one, and the top of the embedded positioning tube 6 is installed inside the corresponding positioning port.

[0032] In this embodiment of the invention, Figure 1As shown, the positioning channel steel 2 is made of U-section profile, the inner cavity width of the positioning channel steel 2 is greater than the width of the rail 1, and the width difference between the inner cavity of the positioning channel steel 2 and the rail 1 is 0.5-1.0 cm. The inner cavity groove of the positioning channel steel 2 is precisely fitted with the rail 1 to form a non-welded inclusive fixed structure. The side wall and bottom of the positioning channel steel 2 provide a double support interface, which not only limits the lateral displacement of the rail 1, but also can achieve leveling of the contact surface of the rail 1.

[0033] In this embodiment of the invention, Figure 1 As shown, the track module also includes a positioning code plate 7, which is symmetrically fixed on the opposite sides of the positioning channel steel 2. A bolt installation cavity 8 is provided on the inclined surface of the positioning code plate 7, and a bolt positioning hole 9 connected to the bolt installation cavity 8 is provided at the bottom of the positioning code plate 7. The bolt positioning hole 9 is connected to the embedded positioning tube 6 at the corresponding position through a positioning bolt. By providing the bolt installation cavity 8 on the positioning code plate 7, it is convenient to install the positioning bolt into the bolt positioning hole 9. The positioning code plate 7 serves as the core connection medium. The welding operation of the positioning code plate 7 only acts on the non-functional surface of the embedded part, which plays the function of limiting the lateral displacement of the positioning channel steel 2. There is no welding intervention on the rail 1 throughout the process, which ensures its structural integrity. During disassembly, there is no need to release the welding node of the positioning code plate 7, and the rail 1 and the positioning channel steel 2 can be recovered without loss.

[0034] In this embodiment of the invention, Figure 1 and Figure 2 As shown, expansion gaps are reserved at both ends of the rail 1 to accommodate thermal deformation. A group of inner bolt mounting holes are provided at the center of the rail waist at both ends of the rail 1. Each group of inner bolt mounting holes consists of two inner bolt mounting holes arranged one above the other. The openings of the inner bolt mounting holes are chamfered at 45° to optimize stress distribution. The rail 1 serves as an active load-bearing body, directly bearing the running load of the master and driven wheels. It adopts a standardized segmented design, and its surface is hardened to reduce wear. Expansion gaps are reserved at both ends to accommodate thermal deformation, ensuring that the friction coefficient is stable under dynamic load conditions and ensuring the safety and reliability of the track connection system.

[0035] In this embodiment of the invention, Figure 2 and Figure 3As shown, the connection module consists of a connecting bolt 10 and a connecting clamp 11. Both ends of the connecting clamp 11 are provided with external bolt mounting holes that are compatible with the internal bolt mounting holes. The connecting bolt 10 passes through the external bolt mounting holes and the internal bolt mounting holes to connect the connecting clamps 11 on both sides. The connecting clamps 11 on both sides cover the waist of the rail 1 to form a mechanical bite. The contact surface of the connecting clamp 11 is laser-engraved with an anti-slip grid, and the spring washer and double nut anti-loosening structure are used to ensure the stability of the friction coefficient under dynamic load conditions. The entire track of the present invention is designed with layered positioning (rail-channel steel-embedded parts) and interface isolation. While ensuring the bearing stiffness, the welding damage is limited to the auxiliary components, so that the main slide rail can be quickly replaced and reused, which significantly reduces the maintenance cost throughout the life cycle.

[0036] Specific embodiment 2, the present invention also includes a method for disassembling and assembling a detachable track, comprising the following steps:

[0037] S01. Place the positioning channel steel 2 on the positioning base 3, and align the bolt positioning holes 9 on the positioning code plates 7 on both sides of the positioning channel steel 2 concentrically with the embedded positioning tube 6, and then connect the positioning bolts to the inside of the embedded positioning tube 6 through the bolt positioning holes 9, so that the connection and fixation between the positioning channel steel 2 and the embedded component module are achieved;

[0038] S02. Install the rail 1 into the positioning channel steel 2. After the positioning channel steel 2 is adjusted, the rail 1 is docked with the rails 1 on both sides. Then, the connecting clamps 11 are fitted on both sides of the waist of the rail 1 so that the outer bolt mounting holes on the connecting clamps 11 are aligned with the inner bolt mounting holes on the rail 1. Then, the connecting bolts 10 are connected and fixed to the connecting clamps 11 on both sides through the outer bolt mounting holes and the inner bolt mounting holes. In this way, the connection module and the two rails 1 are connected and fixed.

[0039] S03. When the entire track needs to be disassembled, first remove the connecting module from each rail 1, then rotate the positioning bolt to disengage it from the positioning code plate 7, and remove the positioning channel steel 2 from the embedded part module. In this way, the disassembly of each rail 1 and the positioning channel steel 2 is completed.
