Description

Technical Field

[0001] This utility model relates to the field of chemical pipeline hoisting technology, and in particular to a hoisting device for chemical pipeline installation. Background Technology

[0002] Chemical pipelines are specialized pipelines used in chemical production to transport media. They are widely used in industries such as chemical, petroleum, and pharmaceutical, and their core function is to safely transport various fluids or gases.

[0003] Existing devices use suction cups to fix pipes, which are difficult to remove and the limiting plate does not provide optimal pipe fixation. Therefore, a pipe installation hoisting device is provided to eliminate the drawbacks of existing devices.

[0004] The existing patent (publication number: CN220723308U) discloses a hoisting device for pipe installation. By placing the pipe in the placement groove, an electric push rod drives the clamping plate to move inward. The clamping blocks set on the clamping plate fix the hollow parts on both sides of the pipe. The connecting ring is connected to the crane. By setting a damper and a shock-absorbing spring between the base plate and the mounting plate, the swaying amplitude is reduced, and the vibration generated after hoisting and lowering can prevent damage to the pipe.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, the diameter and length of the placement groove proposed in these patents are fixed, which makes it inconvenient to obtain stable positioning, especially when hoisting chemical pipelines with large diameters and long lengths, thus affecting the stability of the hoisting.

[0006] Therefore, a hoisting device for chemical pipeline installation is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a hoisting device for installing chemical pipelines, which can solve the problem that the diameter and length of the placement groove in the existing patent are fixed, which is inconvenient to obtain stable positioning and affects the hoisting stability, especially when it is necessary to hoist chemical pipelines with large diameter and long length.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a hoisting device for installing chemical pipelines, including a hoisting rod, with locking mechanisms provided on both sides of the bottom of the hoisting rod, a limiting mechanism provided on the top of the locking mechanism, and a hook fixedly connected to the top of the hoisting rod; the locking mechanism includes two rubber pads, a V-shaped locking plate, and a base plate, with the side of the rubber pad near the inner wall of the V-shaped locking plate fixedly connected to the inner wall of the V-shaped locking plate, and the top of the base plate fixedly connected to the bottom of the V-shaped locking plate.

[0009] Preferably, the limiting mechanism includes a limiting block, a handle, and a connecting frame. The top of the limiting block is fixedly connected to the bottom of the connecting frame, the bottom of the handle is fixedly connected to the top of the connecting frame, and the bottom of the connecting frame is fixedly connected to the top of the V-shaped card plate.

[0010] Preferably, the top of the boom has several limiting grooves, and the limiting block is movably engaged inside the limiting groove.

[0011] Preferably, the bottom of the limiting block has a chamfer.

[0012] Preferably, the number of hooks is several and they are evenly distributed on the top of the boom, and the bottom of the hooks is fixedly connected to the top of the boom.

[0013] Preferably, striking blocks are fixedly connected to both sides of the top of the connecting frame, and the materials of the hanging rod, V-shaped plate, connecting frame, striking blocks and hook are all high-strength alloy structural steel.

[0014] Preferably, a rotating frame is fixedly connected to the bottom of the boom, and the number of rotating frames is several and evenly distributed at the bottom of the boom, with rollers rotatably connected inside the rotating frame.

[0015] Preferably, handles are fixedly connected to both sides of the boom.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This application establishes a clamping mechanism with a V-shaped clamping plate as the core, combined with two rubber pads fixed to the inner wall and a bottom plate, to form a stable chemical pipe clamping structure. The V-shaped structure design can adapt to chemical pipes of various diameters, improving versatility. The rubber pads not only enhance the friction with the pipe surface to prevent displacement of the chemical pipe during hoisting, but also prevent the surface of the chemical pipe from being scratched. The bottom plate contacts the ground to achieve stable placement and provides reliable support for the V-shaped clamping plate. Through linkage with the connecting frame of the limiting mechanism, the clamping mechanism can be adjusted to adapt to the hoisting requirements of chemical pipes of different lengths, solving the problem that the existing equipment placement slot fixation makes it difficult to stably limit the position of large-diameter and long-distance pipes.

[0018] 2. This application incorporates a limiting mechanism, where the connecting frame is fixed to the top of the V-shaped clamping plate, the limiting block, and the handle, forming an integrated operating structure. The handle allows for easy movement of the connecting frame and clamping mechanism. Combined with several limiting grooves on the top of the boom, the limiting block achieves precise positioning. The chamfered design at the bottom of the limiting block prevents jamming during clamping, improving operational smoothness. During hoisting, the limiting block and limiting grooves are tightly clamped, ensuring relative fixation between the clamping mechanism and the boom. Combined with symmetrical connection of the external hoisting rope and hook, this effectively prevents tilting during chemical pipeline hoisting, solving the problem of insufficient hoisting stability caused by the fixed limiting structure in existing equipment, and providing a reliable guarantee for the stable hoisting of pipelines of different specifications.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 The present invention provides the following technical solution:

[0027] A hoisting device for installing chemical pipelines includes a boom 1. Both sides of the bottom of the boom 1 are provided with a clamping mechanism 3. The top of the clamping mechanism 3 is provided with a limit mechanism 4. The top of the boom 1 is fixedly connected with a hook 9. The clamping mechanism 3 includes two rubber pads 301, a V-shaped clamping plate 302 and a base plate 303. The side of the rubber pad 301 near the inner wall of the V-shaped clamping plate 302 is fixedly connected to the inner wall of the V-shaped clamping plate 302. The top of the base plate 303 is fixedly connected to the bottom of the V-shaped clamping plate 302.

[0028] In this embodiment: the operator holds the handles 8 on both sides of the boom 1, and uses the rollers 10 in the rotating frame 7 at the bottom of the boom 1 to reduce friction, moving the boom 1 to the top of the raised chemical pipeline. The connecting frame 403 is then lifted by the handle 402, and the V-shaped clamping plate 302 is fitted onto the pipeline surface. The base plate 303 contacts the ground to provide stable support. The rubber pad 301 increases friction to prevent displacement of the chemical pipeline and protect the pipe surface. The V-shaped structure is adaptable to chemical pipelines of various diameters. The position of the clamping mechanism 3 is adjusted using the limiting groove 2 at the top of the boom 1 and the chamfer 6 at the bottom of the limiting block 401, achieving precise positioning. The external lifting rope and the evenly distributed lifting rods at the top of the boom 1 are then used to complete the process. The hooks 9 are symmetrically connected, and the V-shaped clamps 302 and the chemical pipes must also be placed symmetrically to prevent tilting during hoisting. The striking blocks 5 on both sides of the connecting frame 403 can assist in detachment after hoisting. By selecting hoisting rods 1 of different lengths and multiple V-shaped clamps 302 to adapt to long pipes, the external hoisting equipment is started. The limiting block 401 is tightly engaged with the limiting groove 2, and the V-shaped clamps 302 pull up the chemical pipes, stably hoisting the chemical pipes to complete the operation. This solves the problem that the diameter and length of the placement groove are fixed in the existing patent, which is inconvenient to obtain stable limiting when hoisting chemical pipes with larger diameters and longer lengths, thus affecting the stability of hoisting.

[0029] Specifically, such as Figure 2 As shown, the limiting mechanism 4 includes a limiting block 401, a handle 402 and a connecting frame 403. The top of the limiting block 401 is fixedly connected to the bottom of the connecting frame 403, the bottom of the handle 402 is fixedly connected to the top of the connecting frame 403, and the bottom of the connecting frame 403 is fixedly connected to the top of the V-shaped card plate 302.

[0030] Specifically, such as Figure 2 and Figure 3 As shown, the top of the boom 1 has several limiting grooves 2, and the limiting block 401 is movably engaged inside the limiting groove 2.

[0031] Specifically, such as Figure 2 and Figure 5 As shown, the bottom of the limiting block 401 has a chamfer 6.

[0032] In this embodiment, the limiting mechanism 4 is linked with the handle 402, the connecting frame 403 and the V-shaped card plate 302, making it easy to operate. The limiting block 401 is movably engaged with the limiting groove 2 of the lifting rod 1, which can accurately adjust the position of the engaging mechanism 3 to adapt to different hoisting requirements. The chamfer 6 design at the bottom of the limiting block 401 avoids jamming when inserted into the limiting groove 2, making the engaging process smoother and improving positioning efficiency.

[0033] Specifically, such as Figure 3 As shown, there are several hooks 9 evenly distributed on the top of the boom 1, and the bottom of the hooks 9 are fixedly connected to the top of the boom 1.

[0034] Specifically, such as Figure 2 As shown, striking blocks 5 are fixedly connected to both sides of the top of the connecting frame 403. The materials of the hanging rod 1, V-shaped card plate 302, connecting frame 403, striking blocks 5 and hook 9 are all high-strength alloy structural steel.

[0035] In this embodiment: several evenly distributed hooks 9 ensure that the external hoisting rope can find a balanced stress point to prevent the chemical pipeline from tilting. The striking blocks 5 on both sides of the connecting frame 403 facilitate the V-shaped clamp 302 to detach from the chemical pipeline after hoisting, which is highly practical. The lifting rod 1, V-shaped clamp 302, connecting frame 403, striking blocks 5 and hooks 9 are all made of high-strength alloy structural steel to ensure strength and impact resistance, and are suitable for the stress conditions of chemical pipeline hoisting.

[0036] Specifically, such as Figure 3 and Figure 4 As shown, a rotating frame 7 is fixedly connected to the bottom of the boom 1. There are several rotating frames 7, which are evenly distributed at the bottom of the boom 1. Rollers 10 are rotatably connected inside the rotating frame 7.

[0037] Specifically, such as Figure 3 As shown, handles 8 are fixedly connected to both sides of the boom 1.

[0038] In this embodiment: the rotating frame 7 at the bottom of the boom 1 cooperates with the roller 10 to greatly reduce moving friction, making it easier to adjust the position of the boom 1. The handles 8 on both sides are convenient for operators to hold, making it easy to adjust the position of the boom 1 when cooperating with external hoisting equipment, improving the stability and flexibility of the boom 1 when moving, and simplifying the preparation work before hoisting chemical pipelines.

[0039] Working principle: By holding the handles 8 fixedly connected to both sides, the operator moves the boom 1 to the top of the pre-supported chemical pipeline on the rollers 10, in conjunction with the external hoisting equipment. The rollers 10 effectively reduce the frictional resistance of the boom 1 during movement, improving operational flexibility. Then, the connecting frame 403 is pulled upward by the handle 402 of the limiting mechanism 4, and the V-shaped clamp 302 is fitted onto the surface of the chemical pipeline. At the same time, the boom 1 is located inside the V-shaped clamp 302. The top of the bottom plate 303 of the clamping mechanism 3 is fixedly connected to the bottom of the V-shaped clamp 302, allowing it to contact the ground and be placed stably, providing stable support for the V-shaped clamp 302. The two rubber pads 301 fixedly connected to the inner wall of the V-shaped clamp 302 can increase the contact with the chemical pipeline. The friction on the pipe surface prevents displacement of the chemical pipe during hoisting and avoids scratches on the pipe surface. Meanwhile, the V-shaped structure design allows the clamping mechanism 3 to adapt to chemical pipes of various diameters, improving versatility. Based on the pipe length and hoisting requirements, several limiting slots 2 on the top of the boom 1 are used. The connecting frame 403 and V-shaped clamping plate 302 are moved via the handle 402 to adjust the position of the limiting block 401. The chamfer 6 at the bottom of the limiting block 401 guides it to move more smoothly into the corresponding limiting slot 2, avoiding jamming and achieving precise positioning of the clamping mechanism 3 on the boom 1. Afterwards, the external hoisting rope is fixedly connected to several evenly distributed hooks 9 on the top of the boom 1. During connection, it is necessary to ensure… The connection points between the lifting rope and hook 9, as well as the relative positions of the V-shaped clamp 302 and the chemical pipeline, are symmetrical to prevent pipeline tilting during lifting and ensure lifting stability. The striking blocks 5, fixedly connected to both sides of the top of the connecting frame 403, can be gently tapped to detach the V-shaped clamp 302 from the chemical pipeline after lifting, if they cannot be disengaged. Furthermore, the V-shaped clamp 302, connecting frame 403, striking blocks 5, and hook 9 are all made of high-strength alloy structural steel, ensuring sufficient strength and impact resistance during lifting to meet the stress requirements of chemical pipeline lifting. In addition, by selecting lifting rods 1 of different lengths and different numbers of V-shaped clamps 302, the lifting needs of longer chemical pipelines can be met. After all connections and positioning are completed, the external hoisting equipment is started to lift the hoisting rod 1 upwards. Under the action of the hoisting force, the limiting block 401 is tightly engaged with the limiting groove 2, and then the chemical pipeline is steadily lifted by the engaging mechanism 3, thus completing the hoisting operation of the chemical pipeline. This solves the problem in the existing patents that the diameter and length of the placement groove are fixed, which is inconvenient to obtain stable limiting, especially when hoisting chemical pipelines with large diameters and long lengths, thus affecting the hoisting stability. It should be noted that the external hoisting equipment is a mature technology that has been published, and the contents not described in detail in this specification are all existing technologies known to those skilled in the art. Their basic mechanisms will not be elaborated here.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
