Description

Technical Field

[0001] This utility model belongs to the field of modular prefabricated cabin technology, specifically relating to a modular prefabricated cabin that can be quickly assembled. Background Technology

[0002] Traditional prefabricated modules typically rely on hoisting equipment for transport and positioning, which is not only complex and inefficient, but also requires a large amount of on-site work space and equipment. In particular, when multiple units need to be spliced ​​or angles need to be adjusted according to the site terrain and layout requirements, existing structures often lack flexible and effective adjustment methods, making it difficult to achieve rapid and accurate orientation adjustments.

[0003] Currently, most prefabricated cabin bases and cabins on the market are fixedly connected, or simple slide rails are set on the base for unidirectional movement. This makes it difficult to achieve horizontal rotation adjustment after the cabin is installed. If the orientation needs to be adjusted, the cabin often needs to be lifted again and repositioned, which is time-consuming and labor-intensive. In addition, when splicing multiple prefabricated cabins, the docking between the base guide rails is usually done with simple bolts, which makes it difficult to ensure the continuity and straightness of the guide rails and affects the smooth movement of the cabin on multiple bases. Utility Model Content

[0004] In response to the shortcomings of existing technologies, the inventors have developed a modular prefabricated cabin that can be quickly assembled through long-term practice. It can achieve rapid and precise assembly and fixation, and can realize the rapid assembly of multiple base units and seamless docking with guide rails.

[0005] This utility model discloses a modular prefabricated cabin that can be quickly assembled, comprising a base and a prefabricated cabin body. Two parallel guide rails are fixedly mounted at the top of the base, and a guide groove is formed at the center of the base. A frame is slidably mounted inside the guide groove, and an adjustment disc is rotatably mounted inside the frame. A support rod is fixedly mounted at the center of the adjustment disc. Two retractable slide rails are provided at the bottom of the prefabricated cabin body, and the slide rails are installed at the bottom of the prefabricated cabin body via a retraction mechanism.

[0006] Furthermore, the support rod includes an outer rod and an inner rod sleeved inside it. The outer rod is fixed at the axis of the adjusting disc, and a piston plate is provided inside it that is fixedly connected to the bottom end of the inner rod.

[0007] Furthermore, the retraction mechanism includes a chute formed at the bottom of the prefabricated cabin body, which corresponds to the position of the guide rail. A sleeve is provided inside the chute, and a sliding rod that slides downward along the sleeve wall is provided inside the sleeve. The bottom end of the sliding rod is fixedly connected to the chute.

[0008] Furthermore, the side wall of the sliding rod is provided with several insertion holes, and one end of the sleeve is provided with a positioning hole, into which a connecting pin is inserted.

[0009] Furthermore, the sliding rod sidewall is provided with a plurality of equally spaced insertion holes along the axial direction, and a positioning hole is provided on the corresponding wall of the sleeve.

[0010] Furthermore, the top end of the inner rod is provided with a connecting flange for fixing the top end of the inner rod to the bottom end of the prefabricated cabin body.

[0011] Furthermore, a flange with a through hole is machined at the top of the inner rod, and the flange is fastened to the corresponding flange pre-embedded at the bottom center of the prefabricated cabin body by bolts.

[0012] Furthermore, the end of the guide rail is provided with an embedding groove, the top wall of the embedding groove is provided with a connecting hole, a connecting block is inserted into the inside of the embedding groove, and a bolt hole is provided in the connecting block at a position corresponding to the connecting hole.

[0013] Furthermore, the connecting hole is located inside the guide rail and is a countersunk hole.

[0014] The beneficial effects of this utility model are:

[0015] 1. When adjusting the direction of the prefabricated cabin, the slide rail is retracted by the retraction mechanism, so that the prefabricated cabin body is separated from the base guide rail. At this time, the weight of the prefabricated cabin is borne by the frame and support rod in the center guide groove of the base. The operator can directly push the prefabricated cabin body to rotate horizontally to adjust the direction of the prefabricated cabin body during installation. After the angle adjustment is completed, the slide rail is extended again and locked in the guide rail to complete the fast and accurate splicing and fixing, which can significantly improve the installation efficiency and layout flexibility of the modular prefabricated cabin.

[0016] 2. The hydraulic buffer structure inside the support rod of this utility model ensures smooth rotation, while the pin-type locking mechanism can reliably fix the extension and retraction state of the slide rail. Finally, through the embedded connecting block structure at the end of the guide rail, multiple base units can be quickly spliced ​​and seamlessly connected with the guide rail, thus integrating rapid positioning, flexible orientation adjustment, stable support and modular expansion functions into one.

Detailed Implementation

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0024] See Figures 1-4 This utility model proposes a modular prefabricated cabin that can be quickly assembled, including a base 1 and a prefabricated cabin body 2.

[0025] Two parallel guide rails 3 are fixedly installed at the top of the base 1. A guide groove 4 is formed at the center of the base 1. A frame 5 is slidably installed inside the guide groove 4. The guide groove 4 is T-shaped. A slider that matches the shape of the guide groove 4 is fixedly connected to the bottom of the frame 5. The slider is embedded in the guide groove 4 and can slide along the extension direction of the guide groove 4, so that the frame 5 is restricted within the guide groove 4 to achieve stable linear movement, while being able to withstand vertical loads from above. An adjustment plate 6 is rotatably installed inside the frame 5. The inside of the frame 5 forms a mounting cavity. The adjustment plate 6 is rotatably connected to the frame 5 through a slewing bearing installed inside the mounting cavity. The outer ring of the slewing bearing is fixedly connected to the inner wall of the mounting cavity of the frame 5, and its inner ring is fixedly connected to the lower surface of the adjustment plate 6. A support rod 7 is fixedly installed at the center of the adjustment plate 6.

[0026] The bottom of the prefabricated cabin body 2 is provided with two retractable slide rails 8, which are installed at the bottom of the prefabricated cabin body 2 through a retraction mechanism 9.

[0027] In this embodiment, the guide rail 3 fixed on the base 1 cooperates with the retractable slide rail 8 at the bottom of the prefabricated cabin body 2 to achieve rapid guidance and preliminary positioning of the prefabricated cabin. When the slide rail 8 extends and inserts into the guide rail 3, the prefabricated cabin can slide along the guide rail 3 to the installation position.

[0028] When the orientation of the prefabricated cabin needs to be adjusted, the slide rail 8 is retracted through the retraction mechanism 9, so that the prefabricated cabin body 2 is separated from the guide rail 3. At this time, the weight of the prefabricated cabin is borne by the frame 5 and support rod 7 in the central guide groove 4 of the base 1. The operator can directly push the prefabricated cabin body 2 to rotate horizontally, thereby adjusting the orientation of the prefabricated cabin body 2. After the angle adjustment is completed, the slide rail 8 is extended again and locked in the guide rail 3, which can complete the quick and accurate splicing and fixing, and can significantly improve the installation efficiency and layout flexibility of the modular prefabricated cabin.

[0029] In a further preferred embodiment of this utility model, such as Figure 3 As shown, the support rod 7 includes an outer rod 71 and an inner rod 72 sleeved inside it. The outer rod 71 is fixedly installed at the axis of the adjusting plate 6, and a piston plate is fixedly connected to the bottom end of the inner rod 72 inside it.

[0030] In this embodiment, the bottom of the inner rod 72 forms a sealed cavity with the inner wall of the outer rod 71 through the piston plate. When the prefabricated cabin descends or rotates, the inner rod 72 moves relative to the outer rod 71, driving the piston plate to squeeze the hydraulic oil or gas in the cavity. This generates damping force through the throttling orifice, thereby effectively buffering and absorbing impacts and vibrations, ensuring the smoothness and controllability of the prefabricated cabin attitude adjustment process. The hydraulic buffer structure greatly enhances the stability of the support system under load and rotation, preventing the prefabricated cabin from shaking due to inertia, and improving operational safety and adjustment accuracy.

[0031] In a further preferred embodiment of the present invention, the shrinkage mechanism 9 includes a groove 91, which is opened at the bottom of the prefabricated cabin body 2 and corresponds to the position of the guide rail 3. A sleeve 92 is provided inside the groove 91, and a sliding rod 93 is provided inside the sleeve 92 that slides downward along the wall of the sleeve 92. The bottom end of the sliding rod 93 is fixedly connected to the slide rail 8.

[0032] In this embodiment, the shrinkage mechanism 9 consists of a groove 91 opened at the bottom of the prefabricated cabin body 2, a sleeve 92 fixed in the groove 91, and a sliding rod 93 fixedly connected to the slide rail. The upper end of the sliding rod 93 is slidably sleeved inside the sleeve 92. The sleeve 92 is fixed inside the groove 91 by fastening bolts, and the upper end of the sliding rod 93 is inserted into the inner hole of the sleeve 92. The two form a sliding pair.

[0033] When it is necessary to retract the slide rail 8, pull the slide rail upward, and the sliding rod 93 will retract upward into the sleeve 92 until the slide rail 8 is completely retracted into the prefabricated cabin body 2, thereby achieving separation from the base 1 guide rail 3.

[0034] In a further preferred embodiment of the present invention, the side wall of the sliding rod 93 is provided with a plurality of insertion holes 94, and one end of the sleeve 92 is provided with a positioning hole 95, into which a connecting pin is inserted.

[0035] In this embodiment, a plurality of equally spaced insertion holes 94 are provided on the side wall of the sliding rod 93 along the axial direction, and a positioning hole 95 is provided on the corresponding wall of the sleeve 92.

[0036] When the sliding rod 93 slides to the extended or retracted state, one of the insertion holes 94 aligns with the positioning hole 95. At this time, inserting the connecting pin into the aligned hole will lock the sliding rod 93 and the sleeve 92 in relative position, thereby reliably fixing the sliding rod 93 in the extended or retracted state.

[0037] In a further preferred embodiment of the present invention, a connecting flange is provided at the top end of the inner rod 72 for fixing the top end of the inner rod 72 to the bottom end of the prefabricated cabin body 2.

[0038] In this embodiment, as Figure 3 As shown, a flange with a through hole is machined at the top of the inner rod 72. The flange is fastened to the corresponding flange pre-embedded at the bottom center of the prefabricated cabin body 2 by bolts, thereby forming a rigid force transmission whole between the support rod 7 and the prefabricated cabin body 2. The top of the inner rod 72 and the connecting flange are fixedly connected as a whole by integral forging or welding.

[0039] In a further preferred embodiment of this utility model, such as Figure 3 As shown, the end of the guide rail 3 is provided with an embedding groove 10. The top wall of the embedding groove 10 is provided with a connecting hole 11, and the connecting hole 11 is located inside the guide rail 3 and is a countersunk hole. A connecting block 12 is inserted into the interior of the embedding groove 10, and a bolt hole is provided at the position corresponding to the connecting hole 11 on the connecting block 12.

[0040] In this embodiment, embedding grooves 10 are milled at both ends of each guide rail 3, and countersunk connecting holes 11 are made on the top wall of the grooves. During assembly, a connecting block 12 matching the shape of the embedding groove 10 is inserted into the embedding groove 10, and a long bolt is screwed vertically downward from the connecting hole 11 into the pre-made threaded hole of the connecting block 12, thereby tightening and fixing the ends of two adjacent guide rails 3 together. Specifically, firstly, a connecting block 12 matching the shape of the embedding groove 10 is inserted into the embedding groove 10 at the end of the guide rail 3 of the first base 1. Then, the embedding groove 10 at the end of the guide rail 3 of the second base 1 is aligned and fitted onto the other end of the connecting block 12. At this time, the connecting holes 11 on the two guide rails 3 will be aligned with the bolt holes at both ends of the connecting block 12. Long bolts are then passed through the connecting holes 11 of the first guide rail and the bolt holes at one end of the connecting block 12 in sequence. By tightening the bolts, the ends of the two adjacent guide rails 3 can be pulled together and fixed together through the middle connecting block 12, achieving seamless docking. This enables rapid and precise mechanical interconnection between multiple base units 1, ensuring the continuity and straightness of the guide rails 3 after splicing. It provides a foundation for the smooth movement of the prefabricated cabin on multiple bases 1 and enables large-scale modular expansion.

[0041] The implementation principle of the above embodiment is as follows: the base 1 guide rail 3 and the retractable slide rail 8 at the bottom of the prefabricated cabin are connected to achieve rapid guidance and positioning. After the slide rail is retracted, the weight of the prefabricated cabin is transferred to the central support rod 7. At this time, the cabin can be manually rotated to adjust the angle.

[0042] The hydraulic buffer structure inside the support rod 7 ensures smooth rotation, while the pin-type locking mechanism reliably fixes the extension and retraction state of the slide rail. Finally, through the embedded connecting block 12 structure at the end of the guide rail 3, multiple base units 1 can be quickly spliced ​​and seamlessly connected with the guide rail 3, thus integrating rapid positioning, flexible orientation adjustment, stable support and modular expansion functions.

[0043] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
