Description

Technical Field

[0001] The invention relates to the technical field of modular platform frames, and in particular to a repeated disassembly and assembly positioning and guiding structure for a pool lifting platform. Background Art

[0002] The repeated disassembly and assembly positioning and guiding structure involved in the present invention is used for guiding and positioning during the installation and docking process of the upper and lower structures on the platform of the pool lifting platform retracting and releasing system. The pool lifting platform retracting and releasing system needs to undergo factory commissioning tests, road transportation, on-site installation, repeated disassembly and assembly in water, and is subject to various conditions such as factory conditions, road transportation scale restrictions, on-site installation conditions, and disassembly and assembly conditions in water. The entire pool lifting platform system needs to be a modular assembly structure and be able to meet the requirements of repeated disassembly and assembly. In order to ensure the reliable realization of the repeated disassembly and assembly requirements of the entire pool lifting platform system, a structure is required to ensure the positioning and guiding during the docking process of the upper and lower structures. At present, there are many types of lifting platform products, mainly including climbing platforms and lifting platforms on land, lifting platforms in water, lifting platforms on ships, etc. The land lifting platforms are generally small in structure and cannot meet the needs of pool operations; the lifting platforms in water and on ships are relatively large in structure and cannot meet the needs of repeated disassembly and assembly under the restrictions of on-site installation conditions.

[0003] The overall pool lifting platform is divided into various installation modules, and the modules are extended by connections in different directions to form an overall pool lifting platform. The module body adopts a steel pipe frame structure. Since the overall platform is detachable and reusable, after long-term use, the platform frame is affected by unbalanced gravity and other factors, and after multiple disassembly and use, the modules of the platform frame will inevitably produce slight deformations. Slight deformations accumulate during long-term use, but do not reach the level of module replacement. Therefore, in subsequent use, it is easy to cause the accumulation of overall splicing errors of the platform frame, which is manifested as slight deformations in the longitudinal direction, and then large misalignment of the closed ends in the transverse direction.

[0004] In view of the above, it is necessary to propose a pool lifting platform with a repeated disassembly and assembly positioning and guiding structure to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to overcome the defects in the prior art and provide a repeated disassembly and assembly positioning and guiding structure for a pool lifting platform.

[0006] To achieve the above purpose, the technical solution of the present invention is as follows: A repeated disassembly and assembly positioning and guiding structure for a pool lifting platform, comprising: Assembling modules, each of which is provided with an assembly port, which is arranged at each predetermined position of the assembly module. Different assembly modules are connected to each other through the assembly ports to form a fixed connection and extend in a specific direction, and finally form a pool lifting platform; The positioning guide structure is arranged between two assembly modules to guide and align the assembly ports on different modules during the docking process to ensure the connection accuracy; the positioning guide structure is a rod-shaped guide column with a certain length, and its two ends have guide pin heads respectively inserted into the assembly ports on both sides. After the assembly ports on both sides are spliced ​​together, the positioning guide structure is left in the two assembly ports to form a structural reinforcement for the module assembly joint.

[0007] Furthermore, the assembly port includes a plurality of connecting flanges, which are distributed at four corners of a rectangle formed by the connecting flanges. A positioning groove is recessed in the center of the connecting flange, and the positioning groove cooperates with the guide pin head.

[0008] 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 hole positions. Bolts are passed through the flange holes around the upper and lower flanges and are tightened and fixed.

[0009] Furthermore, the guide pin head is in the shape of a truncated cone, and a plurality of reinforcing ribs are arranged around the back side of the connecting flange.

[0010] Furthermore, the positioning structure also includes an annular protrusion, which is arranged at the connection position between the guide pin heads and the guide columns at both ends, so that when the guide pin heads fully enter the positioning grooves, the annular protrusions just fit on the end faces of the connecting flanges. When the two connecting flanges are connected, the annular protrusions increase the contact area between the positioning guide structure and the flanges, thereby improving the coaxiality of the connecting flanges on both sides after docking.

[0011] Furthermore, the positioning and guiding structure also includes a telescopic adjustment mechanism, and the telescopic adjustment mechanism controls the guide column to be telescopically adjustable along the axial length.

[0012] Furthermore, the telescopic adjustment mechanism includes a hydraulic cylinder body and a cylinder rod body. The cylinder rod body is arranged in the hydraulic cylinder body, a guide pin head is arranged at one end of the hydraulic cylinder body away from the cylinder rod body, a guide pin head is arranged at the free end of the cylinder rod body, an oil supply pipeline is arranged in the annular convex edge on one side of the hydraulic cylinder body, the oil supply pipeline is radially extended on the circular surface of the annular convex edge and is provided with an oil pipe interface, and a stop valve is provided on the oil pipe interface.

[0013] Furthermore, it also includes a thread self-locking structure, the outer wall of the hydraulic cylinder body is provided with an external thread, and a support screw sleeve is threaded on the external thread. The support screw sleeve is adjusted and moved axially and pressed against an annular convex edge on one side.

[0014] Furthermore, the end of the hydraulic cylinder body is provided with a tile-shaped insertion end extending along the axial direction, and an avoidance hole corresponding to the position of the insertion end is provided on the annular convex edge on one side of the cylinder rod body, and multiple tile-shaped insertion ends are arranged evenly spaced around the circumference, and the external thread is arranged along its thread path on the outer wall surface of the insertion end, so that the outer surfaces of the multiple insertion ends form intermittently arranged external threads.

[0015] The advantages and beneficial effects of the present invention are as follows: the present invention provides a repeated disassembly and assembly positioning and guiding structure for a water pool lifting platform, which has a novel structure and an ingenious design. The present invention effectively solves various problems and difficulties caused by various conditions during the factory commissioning test, road transportation, on-site installation, and repeated disassembly and assembly in water of the water pool lifting platform retracting and releasing system. A positioning and guiding structure is provided in the assembly port, so that when the module is assembled and in position, each flange mouth can be accurately aligned, thereby effectively improving the module assembly efficiency; through the improvement of the telescopic adjustment mechanism, when the module has a slight deformation, the telescopic adjustment mechanism can be used to compensate for the bending formed by the assembly between the modules, so that the water pool lifting platform can be assembled and used more smoothly with higher precision.

[0017] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention. Embodiment 1

[0018] A repeatedly disassembling and assembling positioning and guiding structure for a pool lifting platform, comprising: Assemble module 1, such as Figure 1 As shown in the figure, the assembly module 1 is a steel pipe frame structure, and assembly ports 2 are provided at multiple positions thereon. The lifting platform frame can be extended along multiple angles such as longitudinally or transversely through the assembly ports 2 to form a complete lifting platform. The device can achieve the purpose of easy transportation and transfer through modular assembly.

[0019] An assembly port 2 is arranged at each predetermined position of the assembly module 1. In this embodiment, the assembly port 2 includes a plurality of connection flanges 5, and the plurality of connection flanges 5 are distributed at the four corners of the rectangle formed by the assembly port 2. The actual setting shape can be modified as needed. Different assembly modules 1 are connected to each other through the assembly port 2 to form a fixed connection and extend in a specific direction, and finally form a water pool lifting platform. Specifically, in this embodiment, the connection is performed through a positioning guide structure, such as Figure 2 As shown, it is arranged between two assembly modules 1, and guides and aligns the assembly ports 2 on different modules during the docking process to ensure the connection accuracy; the positioning guide structure is a rod-shaped guide column 3 with a certain length, and its two ends have guide pin heads 4 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 truncated cone head, and a positioning groove 6 is provided in the center of the connecting flange 5 to match it. The positioning groove 6 matches 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 as shown in FIG. Figure 1As shown in the position, the distance between the assembly ports 2 on both sides is gradually approached, and then the guide pin head 4 at the upper end of the positioning guide structure is inserted into the positioning groove 6 in the center of the upper flange. In the process of the assembly module 1 falling, the modules on the upper and lower sides are assembled in place under the guidance of the cone surface. The upper and lower flanges are provided with flange holes 7 with aligned holes. Bolts are passed through the flange holes 7 around the upper flange and the lower flange and tightened. Bolts are inserted into a circle of several flange holes 7 to achieve better connection and fixation. Furthermore, a plurality of 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 spliced, the positioning guide structure is left in the two assembly ports 2 to form a structural reinforcement for the module assembly joint. Embodiment 2

[0020] Furthermore, the positioning structure also includes an annular convex edge 9, such as Figure 5 As shown, the annular convex edge 9 is arranged at the connection position between the guide pin head 4 and the guide column 3 at both ends, so that when the guide pin head 4 completely enters the positioning groove 6, the annular convex edge 9 just fits on the end surface of the connecting flange 5. When the two connecting flanges 5 are connected, the annular convex edge 9 increases the contact area between the positioning guide structure and the flange, and improves the coaxiality of the connecting flanges 5 on both sides after docking. Figure 4 As shown, the positioning guide structure also includes a telescopic adjustment mechanism 10, which controls the telescopic adjustment mechanism 10 to adjust the axial length of the guide column 3. 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. Figure 3 shown.

[0021] Furthermore, the telescopic adjustment mechanism 10 includes a hydraulic cylinder body 11 and a cylinder rod body 12. The cylinder rod body 12 is arranged inside the hydraulic cylinder body 11. A guide pin head 4 is arranged at one end of the hydraulic cylinder body 11 away from the cylinder rod body 12. A guide pin head 4 is arranged at the free end of the cylinder rod body 12. An oil supply pipeline 13 is arranged inside the annular convex edge 9 on one side of the hydraulic cylinder body 11. The oil supply pipeline 13 extends radially from the annular surface of the annular convex edge 9 and is provided with an oil pipe interface 14. A stop valve 15 is arranged on the oil pipe interface 14. Figure 5As shown, a manual pressing device is connected to one end of the oil pipe interface 14, and hydraulic oil is injected into the hydraulic cylinder body 11 to push out the guide pin head 4 on the upper side. It can be understood that in actual use, due to certain errors inevitably caused during the welding of different assembly modules 1, it is difficult for multiple flange surfaces at the assembly port 2 to be in the same plane; even if multiple flange surfaces are located on the same plane, the assembly module 1 will produce a certain amount of bending deformation with long-term use. For example, when the assembly module 1 is assembled in the vertical direction, as more modules are assembled, the accumulation of small bending deformations will cause a larger offset when assembled to the upper end. In this embodiment, it can be 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 after monitoring, the flange bolts on the corresponding side can be loosened, and then the oil supply line 13 can be connected, and hydraulic oil can be injected into the positioning guide module, so as to lift it through it. When the predetermined accuracy is reached, the stop valve 15 is closed to allow the hydraulic oil to remain in the hydraulic cylinder body 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 closed end can be avoided. Embodiment 3

[0022] The principle of this embodiment is the same as that of the previous embodiment, except that, in the previous embodiment, hydraulic oil is used to maintain support all the time, which has certain hidden dangers during use. If the hydraulic oil in the hydraulic cylinder 11 leaks, the lifting platform will shake. As an improvement, this embodiment adds a threaded self-locking structure, specifically, Figure 5 , 6 As shown, the outer wall of the hydraulic cylinder body 11 is provided with an external thread 16, and a support screw sleeve 17 is screwed on the external thread 16. The support screw sleeve 17 is adjusted along the axial direction and pressed against the annular convex edge 9 on one side. When in use, after the hydraulic oil is used for lifting, the support screw sleeve 17 is immediately rotated to move upward, so that the upper end surface of the support screw sleeve 17 presses against the annular convex edge 9 on the upper side, so that a long-lasting and safe support can be achieved, and the hydraulic oil in the hydraulic cylinder body 11 can also be depressurized at this time.

[0023] Further, as an improvement of this embodiment, since in the aforementioned structure, when the oil cylinder rod 12 extends upward to the top, if the support screw sleeve 17 is screwed upward, it will be separated from the hydraulic cylinder body 11, and thus cannot provide support, resulting in a small effective support range of the support screw sleeve 17, which cannot meet the support requirements when the oil cylinder rod 12 extends to the maximum stroke; As an improvement, Figure 7As shown, the end of the hydraulic cylinder body 11 is provided with an axially extended tile-shaped insertion end 18, and an annular convex edge 9 on one side of the cylinder rod body 12 is provided with a avoidance hole 19 corresponding to the position of the insertion end 18. When the cylinder rod body 12 is retracted to the bottom end, the insertion end 18 can be inserted into the upper annular convex edge 9 from the avoidance hole 19. When the cylinder rod body 12 is fully extended, since the 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 surfaces of the multiple insertion ends 18 form intermittently arranged external threads 16, and the support screw sleeve 17 can be rotated upward and moved to the external thread 16 on the outer wall of the insertion end 18, and effective support can also be formed. The setting of the insertion end 18 extends the effective support length range of the support screw sleeve 17 for the upper guide pin head 4, and it can stop and support at any point within the effective range.

[0024] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
