[0002] In the field of port logistics and pipeline transfer, the hoisting device for glass steel pipelines has formed a relatively mature application system, and the prior art has certain core advantages: firstly, a hydraulic drive system is generally used, which can provide stable and controllable power output to meet the hoisting load demand of medium and heavy pipelines in the port scene; secondly, most of the devices are equipped with basic clamping structures, which can realize the preliminary fixation of standard specification glass steel pipelines and guarantee the efficiency of conventional transfer operation; and thirdly, some devices integrate the modular design concept, the core components can be individually maintained or replaced, thereby reducing the maintenance cost in long-term use and adapting to the high-intensity and high-frequency operation rhythm of the port. The clamping mechanism spacing of the existing hoisting device is mostly a fixed structure, which cannot be adjusted to adapt to glass steel pipelines of different lengths by itself; meanwhile, the clamping surface is mostly a rigid plane or a simple arc structure, and the contact with the outer circumferential surface of the pipeline is linear contact or local surface contact, which leads to stress concentration and easily causes damage to the pipeline surface; in addition, the clamping component connection mode of some devices is rigid clamping, lacks an anti-skid self-locking structure, and has a loosening risk in the hoisting process, and thus a glass steel pipeline port hoisting device is proposed. SUMMARY

[0003] This section aims to summarize some aspects of the embodiments of the application and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract and title of the specification to avoid obscuring the purpose of this section, abstract and title, and such simplifications or omissions cannot be used to limit the scope of the application.

[0004] In view of the following technical problems in the prior art: the clamping mechanism spacing of the existing hoisting device is mostly a fixed structure, which cannot be adjusted to adapt to glass steel pipelines of different lengths by itself; meanwhile, the clamping surface is mostly a rigid plane or a simple arc structure, and the contact with the outer circumferential surface of the pipeline is linear contact or local surface contact, which leads to stress concentration and easily causes damage to the pipeline surface; in addition, the clamping component connection mode of some devices is rigid clamping, lacks an anti-skid self-locking structure, and has a loosening risk in the hoisting process.

[0005] To solve the above technical problems, the present invention provides the following technical solution: a port lifting device for fiberglass pipes, including a frame assembly, a clamping mechanism and a clamping and bottom supporting mechanism. The frame assembly includes a frame shell, a hydraulic cylinder, a square frame, a movable frame and a receiving frame. The square frame is provided at the bottom of the frame shell and is movably connected to the movable frame. A receiving frame is provided at one end of the movable frame. A clamping mechanism is provided on the lower side of the receiving frame and a clamping mechanism is also provided on the lower side of the square frame. The top of the frame shell is fixedly connected to the movable end of the hydraulic cylinder. The clamping mechanism is equipped with a clamping and supporting mechanism. Through the synergistic effect of the telescopic adjustment function of the frame assembly, the buffer fit design of the clamping mechanism, and the anti-slip reinforcement structure of the clamping and supporting mechanism, the technical problems of poor adaptability to FRP pipes of different lengths and diameters, easy damage to pipes during clamping, and insufficient operational safety of existing equipment are solved, achieving stable, damage-proof, and efficient port lifting operations. The core load-bearing components of the frame assembly, clamping mechanism, and clamping and supporting mechanism are all made of Q355B grade steel, and the attachment blocks of the clamping and supporting mechanism are made of wear-resistant vulcanized rubber, suitable for the humid and dusty working environment of ports. As a preferred technical solution for port lifting equipment for FRP pipes, the side of the frame shell is U-shaped, and the bottom of the inner side of the frame shell is inserted and fixedly connected to the square frame. The U-shaped side design can provide stable accommodation and limiting space for the square frame, which not only ensures the convenience of installation of the square frame, but also enhances the overall structural strength of the frame components and prevents the square frame from loosening and shifting during lifting operations. As a preferred technical solution for port lifting equipment for FRP pipes, the movable frame has a square groove 1 inside, and a square groove 2 at one end of the square frame. A suspension beam is set in the middle of one side of the square groove 2. A hydraulic cylinder 2 is installed in the square groove 1. The suspension beam extends into the square groove 1, and the square groove 1 is movably connected to the suspension beam. The movable end of the hydraulic cylinder 2 is fixedly connected to one end of the suspension beam. The movable cooperation between the square groove 1 and the suspension beam provides guidance for the extension and retraction of the movable frame. The hydraulic cylinder 2 can precisely control the relative displacement between the movable frame and the square frame, realize the flexible adjustment of the clamping mechanism spacing, and meet the lifting requirements of FRP pipes of different lengths.

[0006] As a preferred technical solution for port lifting equipment for FRP pipes, the end of the square frame away from the movable frame is a solid rectangle, and a clamping mechanism is fixed at the bottom of the solid end of the square frame. Compared with the hollow structure, the solid rectangular structure has higher load-bearing strength, can stably support the weight of the clamping mechanism and the lifted pipe, avoid deformation of the end of the square frame due to excessive force, and ensure the structural safety of the lifting operation. As a preferred technical solution for port lifting equipment for FRP pipes, a limit frame is installed on the upper side of the movable frame near the receiving frame. The limit frame is shaped like a "7". A hanging beam is installed on one end of the inner side of the frame shell. The limit frame is movably connected to the lower side of the hanging beam. The cooperation between the "7" shaped limit frame and the hanging beam can accurately limit the maximum extension length of the movable frame, prevent the movable frame from detaching from the square frame due to excessive extension, and avoid safety accidents caused by equipment structural disassembly during lifting. As a preferred technical solution for port lifting equipment for FRP pipes, the clamping mechanism includes a support frame, a clamping frame, a movable slot, a connecting plate, a first connecting platform, a second connecting platform, a structural frame, and a double-headed hydraulic cylinder. Support frames are provided on the lower sides of both the support frame and the square frame. Two movable slots are provided at the bottom of the support frame, with a clamping frame movably inserted into both the front and back of each slot. The two clamping frames on the same side of the movable slot are connected by a connecting plate, a first connecting platform, and a second connecting platform. A double-headed hydraulic cylinder is located in the middle of the movable slot, with its two movable ends fixedly connected to a connecting plate. The clamping mechanism also includes a structural frame, with one structural frame welded to each side of the support frame. The double-headed hydraulic cylinder can drive the clamping frames on both sides to move closer or further away synchronously, ensuring the symmetry and stability of the clamping action. The movable slot provides guidance for the movement of the clamping frame, and the structural frame enhances the lateral support strength of the support frame, preventing the support frame from bending under stress during clamping and improving the overall structural rigidity of the clamping mechanism. As a preferred technical solution for port lifting equipment for FRP pipes, a mating bladder is installed on the connecting platform 2. The inner side of the mating bladder contains hydraulic oil and steel particles. The volume of the steel particles is one-third that of the hydraulic oil, and the particle size is less than 1mm. A clamping and supporting mechanism is installed on the mating bladder. The combination of hydraulic oil and steel particles gives the mating bladder a certain degree of rigidity and deformation capability. This provides stable support for the clamping and supporting mechanism and allows it to adapt to the outer circumference of the pipe through deformation. The steel particles smaller than 1mm ensure the uniformity of the bladder's deformation, preventing loose fit due to excessively large particles. The mixture of hydraulic oil and steel particles inside the mating bladder gives it both rigid support and flexible deformation characteristics, adapting to the outer circumference of FRP pipes with different curvatures. As a preferred technical solution for port lifting equipment for FRP pipes, the clamping mechanism also includes intermediate plates. An intermediate plate is set at the bottom and top of the inner side of the movable groove, and the intermediate plates are slidably connected to the outer side of the top of the clamping frame. The symmetrically arranged intermediate plates can provide bidirectional guidance from the top and bottom of the clamping frame, reduce the shaking when the clamping frame moves, reduce the friction loss between the clamping frame and the movable groove, and ensure the smoothness and accuracy of the clamping action. As a preferred technical solution for port lifting equipment for FRP pipes, the clamping mechanism also includes an elastic connecting seat, a base support frame, and a fitting bladder. An elastic connecting seat is installed on the connecting platform, and a base support frame is installed on one side of the elastic connecting seat. The base support frame is "P"-shaped, and a fitting bladder is installed on the top of the base support frame. The inner side of the fitting bladder contains hydraulic oil. The "P"-shaped base support frame can form a stable support from the bottom of the pipe, the elastic connecting seat can buffer the impact force during clamping, and the hydraulic oil in the fitting bladder can make the bladder fit tightly against the curved surface of the bottom of the pipe, avoiding rigid contact that could cause scratch damage to the surface of the FRP pipe.

[0007] As a preferred technical solution for port lifting equipment for FRP pipes, the clamping and supporting mechanism is equipped with a connecting base plate, a mounting frame, trapezoidal strips, mating grooves, attaching blocks, and anti-slip ridges. The mating bladder is equipped with a connecting base plate, and the connecting base plate is equipped with a mounting frame. A trapezoidal strip is provided on each side of the mounting frame, and the width of the top of the trapezoidal strip is smaller than the width of the bottom of the trapezoidal strip. The material of the attaching block is vulcanized rubber, and a rigid frame is provided on both the front and back of the attaching block. The rigid frame has a mating groove, and the width of the top of the mating groove is smaller than the width of the bottom of the mating groove. The trapezoidal strips correspond one-to-one with the mating grooves, and the trapezoidal strips are inserted into the mating grooves. The side of the attaching block away from the mounting frame is an arc surface and is equipped with densely distributed anti-slip ridges, and the width of the top of the anti-slip ridges is smaller than the width of the bottom of the anti-slip ridges. The trapezoidal structure of the trapezoidal strip and the mating groove enhances the stability of the snap-fit ​​under stress and prevents the attachment block from falling off. The attachment block made of vulcanized rubber is both elastic and wear-resistant. Its arc design fits the outer circumference of the pipe, and the anti-slip ridges increase the friction with the pipe to prevent the pipe from slipping during lifting.

[0008] The beneficial effects of the FRP pipe port lifting equipment of the present invention are as follows: Significantly improved operational performance through reasonable mechanical structure design: Hydraulic cylinder two in the frame assembly controls the extension and retraction of the movable frame, and the precise cooperation between the square groove one and the suspension beam allows for flexible adjustment of the clamping mechanism spacing, achieving stable clamping of long pipes; the cooperation between the limiting frame and the hanging beam effectively limits the maximum extension length of the movable frame, ensuring operational safety. In the clamping mechanism, double-headed hydraulic cylinders drive the clamping frame to move synchronously, and the guiding effect of the intermediate plate improves clamping accuracy; the elastic connecting seat, the fitting bladder, and the deformation design of the fitting bladder reduce clamping impact and effectively protect the pipe's outer surface. In the clamping and supporting mechanism, the trapezoidal strip and the fitting groove interlocking structure provides a more stable connection under pressure, and the anti-slip ridges enhance friction, preventing pipe slippage; the spring structure facilitates pipe detachment, improving operational efficiency. The overall structure optimizes the safety, stability, and adaptability of lifting operations. Attached Figure Description

[0015] like Figures 1-5 As shown, this invention proposes a port lifting device for fiberglass pipes, including a frame assembly 100, a clamping mechanism 200, and a clamping and supporting mechanism 300. The frame assembly 100 includes a frame shell 101, a hydraulic cylinder 102, a square frame 103, a movable frame 104, and a receiving frame 105. The square frame 103 is provided at the bottom of the frame shell 101, and the square frame 103 is movably connected to the movable frame 104. The receiving frame 105 is provided at one end of the movable frame 104, and the clamping mechanism 200 is provided on the lower side of the receiving frame 105. A clamping mechanism 200 is also provided on the lower side of 03. The top of the frame shell 101 is fixedly connected to the movable end of the hydraulic cylinder 102. A clamping and supporting mechanism 300 is provided on the clamping mechanism 200. Through the combination of the frame assembly 100, the clamping mechanism 200 and the clamping and supporting mechanism 300, the lifting equipment can achieve integrated functions of support, clamping and anti-slip. The layout of the double clamping mechanism 200 can improve the clamping stability of the fiberglass pipe. The hydraulic cylinder 102 provides vertical power to the equipment so that the clamped fiberglass pipe can be lifted. The side of the frame shell 101 is U-shaped, and the bottom of the inner side of the frame shell 101 is inserted and fixedly connected to the square frame 103. The frame shell 101 can provide a stable space for the square frame 103 to accommodate and limit, enhance the overall structural strength of the frame assembly 100, and prevent the square frame 103 from loosening or shifting during lifting operations. The movable frame 104 has a square groove 113, and a square groove 115 is provided at one end of the square frame 103. A suspension beam 114 is provided in the middle of one side of the square groove 115. A hydraulic cylinder 112 is provided in the square groove 113. The suspension beam 114 extends into the square groove 113 and is movably connected to the square groove 113. The movable end of the hydraulic cylinder 112 is fixedly connected to one end of the suspension beam 114. The movable cooperation between the square groove 113 and the suspension beam 114 provides guidance for the extension and retraction of the movable frame 104. The hydraulic cylinder 112 can precisely control the relative displacement between the movable frame 104 and the square frame 103, realize the flexible adjustment of the clamping mechanism 200 spacing, and meet the lifting requirements of FRP pipes of different lengths. The end of the square frame 103 away from the movable frame 104 is a solid rectangle, and a clamping mechanism 200 is fixed at the bottom of the solid end of the square frame 103. The solid rectangular structure has higher load-bearing strength than the hollow structure, and can stably support the weight of the clamping mechanism 200 and the suspended pipe, avoiding deformation of the end of the square frame 103 due to excessive force, and ensuring the structural safety of the lifting operation. A limiting frame 107 is provided on the upper side of the movable frame 104 near the receiving frame 105. The limiting frame 107 is shaped like the number "7". A hanging beam 106 is provided on one end of the inner side of the frame shell 101. The limiting frame 107 is movably connected to the lower side of the hanging beam 106. The cooperation between the "7" shaped limiting frame 107 and the hanging beam 106 can accurately limit the maximum extension length of the movable frame 104, preventing the movable frame 104 from detaching from the square frame 103 due to excessive extension, and avoiding safety accidents caused by the disintegration of the equipment structure during the lifting process. The clamping mechanism 200 includes a support frame 201, a clamping frame 202, a movable groove 203, a connecting plate 205, a first connecting platform 206, a second connecting platform 207, a structural frame 211, and a double-headed hydraulic cylinder 215. The support frame 201 is provided on the lower side of the support frame 105 and the square frame 103. The bottom of the support frame 201 is provided with two movable grooves 203. A clamping frame 202 is movably inserted into the front and back of the movable groove 203. The two clamping frames 202 located on the same side of the movable groove 203 are connected by the connecting plate 205, the first connecting platform 206, and the second connecting platform 207. A double-headed hydraulic cylinder 215 is provided in the middle of the movable groove 203. The two movable ends of the double-headed hydraulic cylinder 215 are fixedly connected to a connecting plate 205. The clamping mechanism 200 also includes a structural frame 211. A structural frame 211 is welded to each side of the support frame 201. The double-headed hydraulic cylinder 215 can drive the clamping frames 202 on both sides of the movable groove 203 to move closer or further away synchronously, ensuring the symmetry and stability of the clamping action. The movable groove 203 provides guidance for the movement of the clamping frames 202. The structural frame 211 can enhance the lateral support strength of the support frame 201, prevent the support frame 201 from bending due to force during clamping, and improve the overall structural rigidity of the clamping mechanism 200.

[0016] The connecting platform 207 is equipped with a mating bladder 212. The inner side of the mating bladder 212 contains hydraulic oil and steel particles. The volume of the steel particles is one-third that of the hydraulic oil, and the particle size of the steel particles is less than 1mm. The mating bladder 212 is equipped with a clamping and supporting mechanism 300. The combination of hydraulic oil and steel particles gives the mating bladder 212 a certain rigidity and deformation capacity. It can provide stable support for the clamping and supporting mechanism 300 and adapt to the outer circumference of the pipe through deformation. The steel particles less than 1mm can ensure the uniformity of deformation of the bladder 212 and avoid the particles being too large, which would result in a loose fit.

[0017] The clamping mechanism 200 also includes an intermediate plate 214. An intermediate plate 214 is provided at the bottom and top of the inner side of the movable groove 203. The intermediate plate 214 is slidably connected to the outer side of the top of the clamping frame 202. The symmetrically arranged intermediate plates 214 can provide bidirectional guidance from the top and bottom of the clamping frame 202, reduce the shaking of the clamping frame 202 when it moves, reduce the friction loss between the clamping frame 202 and the movable groove 203, and ensure the smoothness and accuracy of the clamping action. The clamping mechanism 200 also includes an elastic connecting seat 208, a base support 209, and a fitting bladder 210. The elastic connecting seat 208 is provided on the connecting platform 206. The base support 209 is provided on one side of the elastic connecting seat 208. The base support 209 is "P" shaped. The fitting bladder 210 is provided on the top of the base support 209. The inner side of the fitting bladder 210 contains hydraulic oil. The "P" shaped base support 209 can form a stable support from the bottom of the pipe. The elastic connecting seat 208 can buffer the impact force during clamping. The hydraulic oil in the fitting bladder 210 can make the bladder fit tightly against the bottom curved surface of the pipe, avoiding rigid contact that could cause scratch damage to the surface of the fiberglass pipe. The clamping and supporting mechanism 300 is provided with a connecting base plate 301, a mounting bracket 302, a trapezoidal strip 303, a mating groove 304, an attachment block 305, and an anti-slip protrusion 306. The mating bladder 212 is provided with the connecting base plate 301, and the mounting bracket 302 is provided on the connecting base plate 301. A trapezoidal strip 303 is provided on each side of the mounting bracket 302. The width of the top end of the trapezoidal strip 303 is smaller than the width of the bottom end of the trapezoidal strip 303. The attachment block 305 is made of vulcanized rubber. Rigid frames are provided on both the front and back of the attachment block 305. The rigid frames have mating grooves 304. The top of the mating groove 304... The width of the end is smaller than the width of the bottom end of the mating groove 304. The trapezoidal strip 303 corresponds one-to-one with the mating groove 304. The trapezoidal strip 303 is inserted into the mating groove 304. The side of the attachment block 305 away from the mounting bracket 302 is an arc surface and is provided with densely distributed anti-slip protrusions 306. The trapezoidal structure of the trapezoidal strip 303 and the mating groove 304 can enhance the snap-fit ​​stability under force and prevent the attachment block 305 from falling off. The vulcanized rubber attachment block 305 has both elasticity and wear resistance. The arc design adapts to the outer circumference of the pipe. The anti-slip protrusions 306 can increase the friction with the pipe and prevent the pipe from slipping during lifting. Three to five elastic arc strips 213 are evenly arranged between the connecting base plate 301 and the connecting platform 207. The elastic arc strips 213 are made of 65Mn spring steel with a thickness of 2 to 3 mm. They can further adapt to the curvature change of the outer circumference of the pipe through elastic deformation and improve the tightness of the fit.

[0018] The bottom end of the connecting platform 206 is connected to the base bracket 209 by a spring, which is V-shaped.

[0019] When the clamping mechanism 200 is released, the spring can drive the base bracket 209 to swing outward by 15°±2° relative to the connecting platform 206, facilitating the detachment of the fiberglass pipe. The upper side of the connecting bolt 110 is connected to the movable end of the hydraulic cylinder 102.

[0020] The specific implementation method is as follows: The movable frame 104 and the suspension beam 114 are moved relative to each other by the hydraulic cylinder 212. The square groove 113 cooperates with the suspension beam 114, causing the movable frame 104 and the receiving frame 105 to extend, increasing the distance between the two clamping mechanisms 200, thus more stably clamping longer fiberglass pipes. Through the coordinated deformation of the bladder 212 and the elastic arc strip 213, the arc surface of the attachment block 305 automatically adapts to the outer circumference of fiberglass pipes of different diameters, without the need to change the mechanism. The limiting frame 107 cooperates with the hanging beam 106 to limit the maximum extension length of the movable frame 104. When the movable frame 104 reaches its maximum extension length, the limiting frame 107 hangs on the bottom end of the hanging beam 106. The two movable ends of the double-headed hydraulic cylinder 215 pull the two connecting plates 205 closer together. The connecting plates 205, along with the connecting platform 206 and connecting platform 207 on the clamping frame 202, move closer together to clamp the fiberglass pipe. The clamping mechanism 20... When clamped, the elastic connecting seat 208 and the base bracket 209 support the bottom of the FRP pipe. The conforming bladder 210 deforms and adheres to the bottom of the FRP pipe, reducing the impact during clamping to protect the surface of the FRP pipe. The clamping base mechanism 300 clamps the top and middle of the FRP pipe with friction connection. The mating groove 304 mates with the trapezoidal strip 303. The attaching block 305 is subjected to downward pressure. The shapes of the mating groove 304 and the trapezoidal strip 303 ensure their interlocking. It will be more stable. The elastic arc strip 213 and the matching bladder 212 deform, causing the attaching block 305 and the anti-slip ridge 306 to be squeezed and tightly attached to the outer circumference of the fiberglass pipe, increasing the contact area and dispersing the clamping pressure, while ensuring stable clamping. The suspension beam 114 moves relative to the square groove 113 and the movable frame 104 moves relative to the square groove 115. The movable frame 104 is supported by the suspension beam 114 and the square groove 115 in the square frame 103.

[0021] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0022] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
