Description

Technical Field

[0001] This utility model relates to the field of modular platform frame technology, specifically to a reusable disassembly and assembly positioning guide structure for a water tank lifting platform. Background Art

[0002] This utility model relates to a reusable disassembly and assembly positioning guide structure used for guiding and positioning the upper and lower structures during the installation and docking process of a water tank lifting platform deployment and retrieval system. The water tank lifting platform deployment and retrieval system requires factory commissioning tests, road transportation, on-site installation, and repeated disassembly and assembly in water. It is subject to various limitations, including factory conditions, road transportation size restrictions, on-site installation conditions, and underwater disassembly and assembly conditions. Therefore, the entire water tank lifting platform system needs to be a modular assembly structure that can meet the requirements of repeated disassembly and assembly. To ensure the reliable fulfillment of the repeated disassembly and assembly requirements of the entire water tank lifting platform system, a structure is needed to guarantee the positioning and guidance during the docking process of the upper and lower structures. Currently, there are many types of lifting platform products, mainly including land-based aerial platforms, water-based lifting platforms, and ship-based lifting platforms. Land-based lifting platforms are generally relatively small and cannot meet the needs of water tank operations; water-based and ship-based lifting platforms are relatively large and cannot meet the requirements of repeated disassembly and assembly under the limitations of on-site installation conditions.

[0003] The water tank lifting platform is divided into various installation modules. These modules are connected and extended in different directions to form the overall water tank lifting platform. The main body of the module adopts a steel pipe frame structure. Since the overall platform is detachable and reusable, after long-term use, the platform frame will inevitably experience slight deformation due to uneven gravity and other factors, as well as after repeated disassembly and reassembly. Over long-term use, these slight deformations accumulate but do not reach the point of needing to replace the modules. As a result, in subsequent use, this can easily lead to the accumulation of splicing errors in the overall platform frame, manifested as slight deformation in the longitudinal direction, and consequently, larger misalignment at the merging end in the transverse direction.

[0004] In view of the above, it is necessary to propose a reusable disassembly and reassembly positioning and guiding structure for a water tank lifting platform to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to overcome the defects in the existing technology and provide a repetitive disassembly and assembly positioning guide structure for a water tank lifting platform.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: A reusable disassembly and assembly positioning guide structure for a water tank lifting platform, comprising:

[0007] The assembly modules are equipped with assembly ports at predetermined locations on each module. Different assembly modules are connected to each other through the assembly ports to form a fixed structure and extend in a specific direction, ultimately forming a water tank lifting platform.

[0008] The positioning and guiding structure is set between two assembly modules to guide and align the assembly ports on different modules during the alignment process, ensuring connection accuracy. The positioning and guiding structure is a rod-shaped guide post of a certain length, with guide pins at both ends that can be inserted into the assembly ports on both sides. After the assembly ports on both sides are joined, the positioning and guiding structure remains in the two assembly ports, forming a structural reinforcement at the joint of the module assembly.

[0009] Furthermore, the assembly port includes multiple connecting flanges, which are distributed at the four corners of the rectangle they form; a positioning groove is recessed at the center of each connecting flange, and the positioning groove cooperates with the guide pin head.

[0010] Furthermore, the connecting flanges on different assembly ports are divided into upper flanges and lower flanges. The upper and lower flanges are provided with flange holes with aligned positions. Bolts are passed through the flange holes around the upper and lower flanges and tightened to fix them.

[0011] Furthermore, the guide pin head is a frustum-shaped cone, and the back of the connecting flange is provided with multiple reinforcing ribs.

[0012] Furthermore, the positioning structure also includes an annular flange, which is located at the connection between the guide pins and the guide post at both ends. When the guide pins are fully inserted into the positioning groove, the annular flange fits precisely against the end face of the connecting flange. When the two connecting flanges are connected, the annular flange increases the contact area between the positioning guide structure and the flange, thereby improving the coaxiality of the connecting flanges after they are joined.

[0013] Furthermore, the positioning guide structure also includes a telescopic adjustment mechanism, which controls the guide column to extend and retract along its axial length in an adjustable manner.

[0014] Furthermore, the telescopic adjustment mechanism includes a hydraulic cylinder body and a cylinder rod body. The cylinder rod body is installed inside the hydraulic cylinder body. A guide pin is installed at the end of the hydraulic cylinder body away from the cylinder rod body. A guide pin is installed at the free end of the cylinder rod body. An oil supply line is installed inside an annular convex edge on one side of the hydraulic cylinder body. The oil supply line extends radially from the annular convex edge and has an oil pipe interface. A shut-off valve is installed on the oil pipe interface.

[0015] Furthermore, it also includes a threaded self-locking structure, wherein the outer wall of the hydraulic cylinder is provided with an external thread, and a support sleeve is screwed onto the external thread. The support sleeve moves axially to adjust and abuts against a ring-shaped protrusion on one side.

[0016] Furthermore, the end of the hydraulic cylinder body is provided with a tile-shaped insertion end that extends axially, and an annular protrusion on one side of the cylinder rod body is provided with a clearance hole corresponding to the position of the insertion end. Multiple tile-shaped insertion ends are evenly spaced around the circumference, and the external thread is arranged on the outer wall surface of the insertion end along its thread path, so that the outer surface of multiple insertion ends forms an intermittent arrangement of external threads.

[0017] The advantages and beneficial effects of this utility model are as follows: This utility model provides a novel and ingeniously designed positioning and guiding structure for a water tank lifting platform, which is designed for repeated disassembly and assembly. This utility model effectively solves various problems and difficulties caused by various conditions during factory commissioning and testing, road transportation, on-site installation, and repeated disassembly and assembly in water for the water tank lifting platform's deployment and retrieval system. The positioning and guiding structure within the assembly port ensures precise alignment of the flanges during module assembly, effectively improving module assembly efficiency. Furthermore, the improved telescopic adjustment mechanism compensates for slight deformation of the modules, allowing for smoother assembly and use of the water tank lifting platform with higher precision.

[0026] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0027] Example 1:

[0028] A reusable disassembly and assembly positioning and guiding structure for a water tank lifting platform includes:

[0029] Assemble module 1, such as Figure 1 As shown in the figure, the assembly module 1 is a steel pipe frame structure, with assembly ports 2 at multiple locations on it. Through the assembly ports 2, the lifting platform frame can be extended at multiple angles such as longitudinal or transverse to form a complete lifting platform. This device can achieve the purpose of convenient transportation and transfer through modular assembly.

[0030] Assembly ports 2 are arranged at various predetermined positions of assembly module 1. In this embodiment, the assembly port 2 includes multiple connecting flanges 5, which are distributed at the four corners of the rectangle formed by them. The actual arrangement shape can be modified as needed. Different assembly modules 1 are connected to each other through assembly ports 2 to form a fixed structure and extend in a specific direction, and finally form a water tank lifting platform.

[0031] Specifically, in this embodiment, the connection is achieved through a positioning and guiding structure, such as... Figure 2 As shown, it is positioned between two assembly modules 1, guiding and aligning the assembly ports 2 on different modules during the alignment process to ensure connection accuracy; the positioning guide structure is a rod-shaped guide post 3 of a certain length, with guide pins 4 at both ends that are respectively inserted into the assembly ports 2 on both sides, specifically, as shown... Figure 1 , 2 As shown, the guide pin head 4 is a frustum-shaped cone, and a positioning groove 6 is recessed in the center of the connecting flange 5 to cooperate with it. The positioning groove 6 cooperates with the guide pin head 4. Figure 1 As shown, the connecting flanges 5 on different assembly ports 2 are divided into upper flanges and lower flanges. During assembly, the positioning guide structure is placed in the positioning groove 6 in the center of the lower flange, and the upper assembly module 1 is hoisted to the position by means of hoisting or other methods. Figure 1 As shown, the assembly ports 2 on both sides are brought closer together. Then, the guide pin 4 at the top of the positioning guide structure is inserted into the positioning groove 6 in the center of the upper flange. During the descent of the assembly module 1, the modules on both sides are aligned and guided by the conical surface. The upper and lower flanges have flange holes 7 with aligned holes. Bolts are passed through the flange holes 7 around the upper and lower flanges and tightened. Bolts are inserted into several flange holes 7 around the perimeter to achieve a better connection and fixation. Furthermore, multiple reinforcing ribs 8 are provided around the back of the connecting flange 5 to improve the strength of the flange surface. After the assembly ports 2 on both sides are joined, the positioning guide structure remains in the two assembly ports 2, forming a structural reinforcement at the module assembly joint.

[0032] Example 2:

[0033] Furthermore, the positioning structure also includes an annular protrusion 9, such as... Figure 5 As shown, the annular flange 9 is located at the connection between the guide pins 4 and the guide post 3 at both ends. When the guide pins 4 are fully inserted into the positioning groove 6, the annular flange 9 fits precisely against the end face of the connecting flange 5. When the two connecting flanges 5 are connected, the annular flange 9 increases the contact area between the positioning guide structure and the flange, improving the coaxiality of the connecting flanges 5 after they are joined. Its exploded view is shown below. Figure 4 As shown, the positioning guide structure also includes a telescopic adjustment mechanism 10, which controls the guide column 3 to extend and retract along its axial length for adjustable length. The extension length of the cylinder rod 12 can be adjusted by injecting hydraulic oil, thereby changing the total length of the entire positioning guide structure, such as... Figure 3 As shown.

[0034] Furthermore, the telescopic adjustment mechanism 10 includes a hydraulic cylinder body 11 and a cylinder rod 12. The cylinder rod 12 is disposed inside the hydraulic cylinder body 11. A guide pin 4 is disposed at the end of the hydraulic cylinder body 11 away from the cylinder rod 12. A guide pin 4 is disposed at the free end of the cylinder rod 12. An oil supply line 13 is disposed within an annular flange 9 on one side of the hydraulic cylinder body 11. An oil supply line 13 extends radially from the annular surface of the annular flange 9 and has an oil pipe interface 14. A shut-off valve 15 is disposed on the oil pipe interface 14. Figure 5As shown, a manual pressure device is connected to one end of the oil pipe interface 14 to inject hydraulic oil into the hydraulic cylinder 11, pushing out the upper guide pin head 4. It is understandable that in actual use, due to inevitable errors during the welding and fabrication of different assembly modules 1, it is difficult for multiple flange faces at the assembly port 2 to be on the same plane. Even if multiple flange faces are on the same plane, with prolonged use, the assembly module 1 will undergo a certain amount of bending deformation. For example, when assembling the assembly module 1 vertically, as more modules are assembled, the accumulation of small bending deformations will result in a larger offset when assembled to the upper end. In this embodiment, it is possible to... By adjusting the verticality one by one during the assembly process, specifically, for example, during longitudinal assembly, when the installed module is slightly tilted on one side of the monitoring phase, the flange bolts on the corresponding side can be loosened, and then the oil supply line 13 can be connected to inject hydraulic oil into the positioning guide module, thereby lifting it to the predetermined accuracy. When the predetermined accuracy is reached, the shut-off valve 15 is closed, so that the hydraulic oil remains in the hydraulic cylinder 11 to maintain support, and then the bolts are tightened. In this way, the slight tilting phenomenon of the lifting platform frame caused by the accumulation of slight deformation of the assembly module 1 can be dealt with, so that the overall verticality and horizontality of the assembled lifting platform meet the requirements, and the misalignment of the assembly module 1 at the closing end is avoided.

[0035] Example 3:

[0036] This embodiment is based on the same principle as the previous embodiment, but the difference lies in that, in the previous embodiment, hydraulic oil was used to maintain support at all times, which posed certain risks during use. If the hydraulic oil in the hydraulic cylinder 11 leaked, the lifting platform would shake. As an improvement, this embodiment adds a threaded self-locking structure, specifically, as follows: Figure 5 , 6 As shown, the outer wall of the hydraulic cylinder body 11 is provided with an external thread 16, and a support sleeve 17 is screwed onto the external thread 16. The support sleeve 17 moves axially to adjust and abut against the annular flange 9 on one side. In use, after being lifted by hydraulic oil, the support sleeve 17 is rotated to move it upward, so that the upper end face of the support sleeve 17 abuts against the upper annular flange 9. This can achieve a durable and safe support, and at this time, the hydraulic oil in the hydraulic cylinder body 11 can also be depressurized.

[0037] Furthermore, as an improvement to this embodiment, since the cylinder rod 12 in the aforementioned structure will detach from the hydraulic cylinder 11 when the support sleeve 17 is screwed upward when it extends to the top, it will be unable to provide support. As a result, the effective support range of the support sleeve 17 is small and cannot meet the support requirements when the cylinder rod 12 extends to its maximum stroke.

[0038] As an improvement, such as Figure 7As shown, the end of the hydraulic cylinder body 11 is provided with a tile-shaped insertion end 18 extending axially. An annular protrusion 9 on one side of the cylinder rod 12 is provided with a relief hole 19 corresponding to the position of the insertion end 18. When the cylinder rod 12 is retracted to the bottom, the insertion end 18 can be inserted into the annular protrusion 9 on the upper side through the relief hole 19. When the cylinder rod 12 is fully extended, since multiple tile-shaped insertion ends 18 are evenly spaced around the circumference, the external thread 16 is arranged along its thread path on the outer wall surface of the insertion end 18, so that the outer surface of multiple insertion ends 18 forms an intermittent arrangement of external threads 16. The support sleeve 17 can be rotated upward and moved to the external thread 16 on the outer wall of the insertion end 18, which can also form effective support. The setting of the insertion end 18 extends the effective support length range of the support sleeve 17 for the upper guide pin head 4, and can stop and provide support at any point within this effective range.

[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
