Description

Technical Field

[0001] The utility model belongs to the technical field of pipe hoisting, and in particular relates to an integrated sleeve-shaped hoisting device for hoisting pipes. Background Art

[0002] Pipes are important components for fluid transportation. Using pipes when transporting fluid substances can achieve high efficiency and safety, and different fluid substances require different pipes. Some fluid substances have special requirements for maintaining their properties during transportation. When it is necessary to maintain certain properties of the fluid, requirements are also placed on the thermal insulation performance of the pipes, and even a thermal insulation layer is formed on the pipes. This type of pipe requires special protection of the surface structure during transportation. Conventional lifting uses a sling that is sleeved on the surface of the pipe. If the pipe tilts during the lifting process, the sling may slip along the surface of the pipe, which will cause damage to the surface structure of the pipe, seriously affecting the subsequent use of the pipe. In addition, the port of the pipe is easily deformed or even damaged due to bumps during the lifting process, which can easily affect the connection, installation, and sealing of the pipe.

[0003] It can be seen that the current pipe lifting scheme still has room for improvement. It should be optimized to improve the stability and reliability of pipe lifting and protect the surface structure of the pipe from damage. At the same time, the pipe ends should be protected to prevent damage caused by bumps. Therefore, a more reasonable technical solution should be proposed to solve the technical problems existing in the current lifting. Utility Model Content

[0004] To overcome at least one of the aforementioned drawbacks, the present invention proposes an integrated sleeve-shaped lifting device for lifting pipes. The lifting device cooperates with the pipe to securely lift the pipe, keeping the connection position on the pipe relatively fixed, protecting the pipe's surface structure, such as its anti-corrosion and insulation layers. It also protects the pipe's ports, preventing damage from knocks and collisions. This ensures the safety and reliability of the pipe during lifting.

[0005] In order to achieve the above-mentioned purpose, the sling set disclosed in the present utility model can adopt the following technical solutions:

[0006] An integrated sleeve-shaped lifting device for lifting pipes, which is used to lift the ends of the pipes, comprises:

[0007] Hanging sleeves, at least two in number, used to fit the ends of the wrapped pipes;

[0008] The sling is matched with the lifting sleeve in a one-to-one manner and is used to lift and lock the lifting sleeve; the sling includes a ring structure extending along the lifting sleeve and forming a ring structure around the pipe wall. When the sling is lifted and force is applied to the ring structure, the ring structure is tightened and when force is applied downward, the ring structure is loosened.

[0009] The integrated lifting device disclosed above, after the lifting sleeve is engaged with the end of the pipe, is connected to an external lifting device via a lifting belt for lifting and hoisting. The upward pulling force on the lifting belt causes the collar structure to tighten and enclose the pipe, keeping the lifting sleeve in close contact with the pipe and lifting the pipe. When the pipe is hoisted and placed in place, the collar structure can be loosened by pulling downward, so that the lifting sleeve can be quickly removed from the pipe and the lifting device can be disassembled. This lifting device can quickly cooperate with the pipe for lifting and maintains a close fit with the end of the pipe during the lifting process, avoiding scratches and damage to the surface structure of the pipe, such as the anti-corrosion layer and the thermal insulation layer. At the same time, the lifting sleeve wraps and seals the end of the pipe, forming a good protective structure, which can prevent the end from being damaged by force.

[0010] Furthermore, when the hanging sleeve is fitted with the pipe end, the structure of the hanging sleeve can be constructed in various forms to maintain a close fit with the pipe, thereby achieving a stable connection and good wrapping. The structure of the hanging sleeve is not limited to a single one. Here, we optimize and propose one feasible option: the hanging sleeve includes a cylindrical pipe sleeve portion, one end of which is closed and forms the sleeve bottom. The sleeve bottom and the pipe sleeve portion are integrally formed or spliced. When adopting this solution, the pipe sleeve portion fits the outer circumference of the pipe and the sleeve bottom fits the pipe end, which can not only maintain the relative position of the hanging sleeve and the pipe, but also protect the pipe end.

[0011] Furthermore, to protect the pipe ends, better vibration isolation and damping structures can be provided to enhance protection. This can be achieved through various design options, which are not intended to be exclusive. Here, we present an optimized and feasible option: a cushion formed within the pipe sleeve. With this solution, the cushion fits the pipe end and provides elastic protection, reducing vibrations experienced by the pipe end.

[0012] Furthermore, the cushioning pad protects the pipe end, reducing impacts and knocks. The bottom of the sleeve should also be optimized to improve overall strength. Various solutions are possible, and are not intended to be exclusive. Here, we present one feasible option: a reinforcement pad connected to the bottom of the sleeve. In this solution, the reinforcement pad is integrally formed from a high-strength material, such as high-strength rubber. This can withstand the pressure from the pipe end, ensuring contact with the pipe end without deformation or damage.

[0013] Furthermore, the loop structure formed by the sling and the pipe sleeve can exert a restraining force on the pipe, thereby improving the tightness of the fit between the pipe sleeve and the pipe. The specific configuration of the loop structure is not limited to a single method. Here, an optimization and feasible option is proposed: the pipe sleeve is formed with a retaining structure to accommodate the sling, and the sling extends along the retaining structure and wraps around the pipe at least once. With this solution, after the sling wraps around the pipe, it is pulled upward to tighten the pipe.

[0014] Furthermore, to enhance the protection of the pipe, the sling can be isolated from the pipe by a flexible layer. While this specific arrangement is not strictly limited, an optimization and feasible option is proposed herein: the pipe sleeve comprises an inner layer and an outer layer, the retaining structure comprises a surrounding channel formed between the inner and outer layers to accommodate the sling, and the outer layer is provided with a first channel opening for the sling to pass through. In this arrangement, the sling is wound within the surrounding channel and extends outward through the first channel opening, tightening when subjected to an upward pull.

[0015] Furthermore, the arrangement of the sling around the pipe surface is not limited to a single method; various solutions are possible. Here, we propose an optimized and feasible alternative: the aforementioned retaining structure includes a loop formed in the pipe sleeve, the loop surrounding the pipe sleeve, and the sling passing through the loop to form a loop structure. In this arrangement, an opening is left at the top of the loop, through which the sling can be inserted and removed.

[0016] Furthermore, when the sling is wrapped around the limiting structure, it can adopt a variety of wrapping methods. Here, we optimize and propose feasible options: the sling adopts a unidirectional wrapping method to form a loop structure, that is, the front end of the sling enters the limiting structure, wraps around it, then leaves the limiting structure and slides with the middle part of the sling; or the sling adopts a bidirectional wrapping method to form a loop structure, that is, the front end of the sling enters the limiting structure, wraps around it, then leaves the limiting structure, continues to extend and synchronously connects with the rear end of the sling. When such a solution is adopted, the loop structure formed by the sling is a movable structure that can be tightened when the lifting ring is lifted. At the same time, after the lifting is completed, the loop structure can be loosened by applying downward force.

[0017] Furthermore, when loosening the collar structure, a force can be applied in a variety of ways to loosen the collar structure and facilitate removal of the sling. While the method for loosening the collar structure is not limited to a single method, an optimization is provided herein, in which a pull-down release assembly is connected to the collar structure. In this embodiment, the pull-down release assembly can pass through the second passage opening of the sleeve portion or extend from the opening at the bottom of the rope loop to apply the pull-down force.

[0018] Furthermore, the pull-down release mechanism can be constructed in a variety of configurations, which are not limited to a single one. Here, we optimize and propose one feasible option: the pull-down release assembly includes a pull cord, and a pull ring can be provided at the end of the pull cord. In this solution, the pull cord is connected to the loop structure, and the pull ring drives the pull cord downward to release the loop structure.

[0019] Furthermore, when removing the sleeve from the pipe end, external force is required to remove the sleeve. This force can be applied in a variety of ways, and is not limited to a single method. Here, we propose an optimized and feasible option: a pull-off assembly is connected to the bottom of the sleeve. In this solution, the pull-off assembly applies external force to pull the sleeve away from the pipe.

[0020] Furthermore, the pull-and-release assembly can be configured in various ways to apply force outward, and is not limited to a single structure. Here, we propose an optimized and feasible option: the pull-and-release assembly includes a pull-and-release rope connected to the bottom of the sleeve. When this solution is adopted, a pull-and-release ring can also be provided on the pull-and-release rope to facilitate gripping and applying force.

[0021] Compared with the prior art, some of the beneficial effects of the technical solution disclosed in this utility model include:

[0022] The utility model can keep the lifting strap in a relatively fixed position by cooperating with the end of the pipe through the lifting sleeve, preventing the lifting strap from sliding relative to the pipe during the lifting process and causing scratches and damage. At the same time, the lifting sleeve also wraps and seals the end of the pipe, forming a closed protective structure to prevent damage to the pipe end due to bumps. Therefore, during the lifting process, the surface structure of the pipe, such as the anti-corrosion layer and the thermal insulation layer, is protected, as well as the end structure of the pipe.

[0029] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments.

[0030] In view of the many deficiencies in the existing lifting equipment, the following embodiments are optimized and overcome the defects in the existing technology.

[0031] Example

[0032] like Figure 1 As shown, this embodiment provides an integrated sleeve-shaped lifting device for lifting a pipe 1, which cooperates with the end of the pipe 1 for lifting, including:

[0033] There are at least two hanging sleeves 2 for wrapping the ends of the pipe 1;

[0034] The sling 5 corresponds to the sling sleeve 2 one by one and is used to lift and lock the sling sleeve 2; the sling 5 includes a ring structure 501 extending along the sling sleeve 2 and forming a ring structure around the wall of the pipe 1. When the sling 5 is lifted and a force is applied to the ring structure 501, it is tightened, and when a force is applied downward, the ring structure 501 is loosened.

[0035] Preferably, the sling 5 in this embodiment is made of high-strength nylon material.

[0036] The integrated set sling disclosed in this embodiment, after the lifting sleeve 2 is matched with the end of the pipe 1, is connected to the external lifting equipment through the lifting belt 5 for lifting and hoisting. The upward pulling force on the lifting belt 5 will tighten the ring structure 501 and wrap around the pipe 1, keeping the lifting sleeve 2 in close contact with the pipe 1 and lifting the pipe 1; when the pipe 1 is hoisted and placed in place, the ring structure 501 can be loosened by pulling it downward, so that the lifting sleeve 2 can be quickly removed from the pipe 1 to achieve the removal of the sling. This sling can quickly cooperate with the pipe 1 for hoisting, and maintain a close fit with the end of the pipe 1 during the hoisting process to avoid scratches and damage to the surface structure of the pipe 1; at the same time, the lifting sleeve 2 wraps and closes the end of the pipe 1, forming a good protective structure to prevent the end from being damaged by force.

[0037] like Figure 2As shown, when the hanging sleeve 2 is fitted with the end of the pipe 1, the structure of the hanging sleeve 2 can be constructed in various forms to maintain contact with the pipe 1 so as to achieve stable connection and good wrapping. The structure of the hanging sleeve 2 is not limited to a single one. This embodiment is optimized and adopts one of the feasible options: the hanging sleeve 2 includes a cylindrical pipe sleeve portion 201, one end of the pipe sleeve portion 201 is closed and forms a sleeve bottom 202, and the sleeve bottom 202 is integrally formed or spliced ​​with the pipe sleeve portion 201. When such a solution is adopted, the pipe sleeve portion 201 is in contact with the outer periphery of the pipe 1, and the sleeve bottom 202 is in contact with the end of the pipe 1, which can not only keep the relative position of the hanging sleeve 2 and the pipe 1 fixed, but also protect the end of the pipe 1.

[0038] To protect the end of the pipe 1, a better vibration isolation and damping structure can be provided to enhance the protection of the end of the pipe 1. This effect can be achieved through various configurations, which are not limited to a single solution. This embodiment optimizes and adopts one feasible option: a cushion 7 is formed within the pipe sleeve 201. When this solution is adopted, the cushion 7 fits the end of the pipe 1 and provides elastic protection, thereby reducing the vibration to the end of the pipe 1.

[0039] The protection provided by the cushion 7 to the end of the pipe 1 can reduce impacts and knocks. The bottom 202 of the sleeve should also be optimized to improve overall strength. Various solutions are possible, and are not intended to be limiting. This embodiment optimizes and adopts one feasible option: a reinforcement pad 8 is connected to the sleeve bottom 202. When this solution is adopted, the reinforcement pad 8 is integrally formed from a high-strength material, such as high-strength rubber, to withstand the pressure from the end of the pipe 1 and achieve abutment against the end of the pipe 1 without deformation or damage.

[0040] The loop structure 501 formed by the sling 5 and the sleeve portion 201 can exert a restraining force on the pipe 1, thereby improving the tightness of the fit between the sleeve portion 201 and the pipe 1. The specific configuration of the loop structure 501 is not limited to a single method. This embodiment optimizes and adopts one feasible option: the sleeve portion 201 is formed with a retaining structure to accommodate the sling 5. The sling 5 extends along the retaining structure and wraps around the pipe 1 at least once. In this solution, after the sling 5 wraps around the pipe 1, it is tightened and wrapped around the pipe 1 by the upward pulling force.

[0041] In order to enhance the protection effect of the pipe 1, the flexible layer can be used to isolate the sling 5 from the pipe 1. The specific setting method is not limited to the only one. This embodiment is optimized and adopts one of the feasible options: Figure 3As shown, the sleeve portion 201 comprises an inner layer 2a and an outer layer 2b. The retaining structure includes a surrounding channel 203 formed between the inner and outer layers 2a, 2b to accommodate the sling 5. The outer layer 2b is provided with a first channel opening for the sling 5 to pass through. In this arrangement, the sling 5 is wound within the surrounding channel 203 and extends outward through the first channel opening, tightening when subjected to an upward pulling force.

[0042] The arrangement of the sling 5 around the surface of the pipe 1 is not limited to a single method, and a variety of schemes can be adopted. This embodiment is optimized and adopts another feasible option: Figure 2 As shown, the limiting structure includes a rope loop 6 formed on the sleeve portion 201. The rope loop 6 is arranged around the sleeve portion 201, and the sling 5 passes through the rope loop 6 to form a loop structure 501. When such a solution is adopted, an opening is left at the top of the rope loop 6, and the sling 5 can enter and exit through the opening.

[0043] When the sling 5 is wrapped around the limiting structure, it can adopt a variety of wrapping methods. This embodiment optimizes and adopts feasible options: the sling 5 adopts a unidirectional wrapping method to form a loop structure 501, that is, the front end of the sling 5 enters the limiting structure, wraps around it, then leaves the limiting structure and slides with the middle part of the sling 5; or the sling 5 adopts a bidirectional wrapping method to form the loop structure 501, that is, the front end of the sling 5 enters the limiting structure, wraps around it, then leaves the limiting structure, continues to extend, and synchronously connects with the rear end of the sling 5. When this solution is adopted, the loop structure 501 formed by the sling 5 is a movable structure that can be tightened when the lifting ring is lifted. At the same time, after the lifting is completed, the loop structure 501 can be loosened by applying downward force.

[0044] When loosening the collar structure 501, a variety of methods can be used to apply force, thereby loosening the collar structure 501 to facilitate removal of the sling 2. The method for loosening the collar structure 501 is not limited to a single method. This embodiment optimizes and adopts one feasible option: the collar structure 501 is connected to a pull-down release assembly 3. In this method, the pull-down release assembly 3 can pass through the second passage opening of the sleeve portion 201 or extend from the opening at the bottom of the rope loop 6 to achieve the pull-down force.

[0045] Preferably, in this embodiment, the length of the pull-down release component 3 can be set to be longer, and can also be used as a traction rope during the lifting process to help maintain the lifting direction of the pipe 1 and keep the lifting smooth.

[0046] The pull-down release structure can be constructed in a variety of configurations, which are not limited to a single configuration. This embodiment optimizes and adopts one feasible option: the pull-down release assembly 3 includes a pull rope 301, and a pull ring 302 can be provided at the end of the pull rope 301. In this solution, the pull rope 301 is connected to the ring structure 501, and the pull ring 302 drives the pull rope 301 downward to loosen the ring structure 501.

[0047] When removing the hanging sleeve 2 from the end of the pipe 1, external force is required to remove the hanging sleeve 2. This force can be applied in a variety of ways, which are not limited to the only ones. This embodiment optimizes and adopts one feasible option: the sleeve bottom 202 is connected to a pull-out assembly 4. When this solution is adopted, the pull-out assembly 4 applies external force to pull the hanging sleeve 2 away from the pipe 1.

[0048] The pull-and-release assembly 4, which applies outward force, can be constructed in a variety of ways and is not limited to a single structure. This embodiment optimizes and adopts one feasible option: the pull-and-release assembly 4 includes a pull-and-release rope 401 connected to the sleeve bottom 202. When this solution is adopted, a pull-and-release ring 402 can also be provided on the pull-and-release rope 401 to facilitate gripping and applying force.
