Description

Technical Field

[0001] This utility model relates to the field of hoisting equipment technology, specifically to a pipe loading hoist. Background Technology

[0002] Pipes are a basic material widely used in industry, construction, and other fields. After processing, they need to be hoisted, transferred, and loaded for transportation. In traditional hoisting methods, rigid binding tools such as steel wire ropes and metal chains are commonly used to fix the pipes, and then the entire pipe is lifted and transferred by a gantry crane or crane. However, such rigid tools are prone to causing scratches, indentations, and other damage to the surface of the pipes, which has a significant impact on the quality of anti-corrosion coatings or precision pipes.

[0003] To reduce pipe damage, existing technologies are increasingly using flexible materials (such as nylon strapping and synthetic fiber lifting slings) to replace rigid binding tools. This involves wrapping the pipe around its center and tightening it before lifting. While this method reduces the risk of surface damage, it still has significant drawbacks:

[0004] Relying solely on manual wrapping and tightening of the cable tape makes it difficult to ensure the uniformity of binding multiple pipes. During hoisting, uneven stress can easily cause the pipes to scatter, posing a safety hazard.

[0005] Therefore, this application proposes a pipe loading hoist. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a pipe loading hoist, which solves the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A pipe loading hoist, comprising:

[0009] Base;

[0010] Two shaped panels are symmetrically arranged on the top of the base, with the middle of the shaped panels fixed to the base.

[0011] The connecting mechanism consists of two sets, which are symmetrically installed at both ends of the two plastic plates on opposite sides.

[0012] A fixing plate is rotatably mounted on a connecting mechanism. One fixing plate has a cloth strap fixedly connected to its top, and the other fixing plate has a perforation.

[0013] The connecting frame is movably fitted outside the fabric strip, and the top of the connecting frame has an integrally formed connecting ring, which is used to attach to the hook;

[0014] A snap-fit ​​mechanism is installed at the other end of the fabric belt. The snap-fit ​​mechanism can pass through the perforation and snap-fit ​​with the fixing plate.

[0015] Furthermore: the snap-fit ​​mechanism includes a snap-fit ​​block fixedly installed at the end of the fabric tape. The snap-fit ​​block can pass through the through hole. A groove is provided on the snap-fit ​​block. A snap-fit ​​plate is hinged on the snap-fit ​​block and located in the groove. A limiting plate perpendicular to the snap-fit ​​plate is integrally formed on the snap-fit ​​plate. When the end of the snap-fit ​​plate extends into the through hole, the limiting plate can abut against the fixed plate. When the free end of the snap-fit ​​plate is located outside the snap-fit ​​block, the limiting plate can move through the through hole.

[0016] Furthermore: the base includes two base plates, which are symmetrically arranged. Telescopic rods are symmetrically fixedly installed on opposite sides of the two base plates. The two plastic plates can be moved closer or further apart along the two telescopic rods through the two sets of connecting mechanisms. The two plastic plates are respectively fixedly installed on the two base plates.

[0017] Furthermore: the connecting mechanism includes two connecting shells respectively fixedly installed on opposite sides of the two plastic plates, each connecting shell having a threaded rod threaded through it on opposite sides, and a connecting rod fixedly connected to the opposite sides of the two threaded rods, with the fixing plate rotatably installed in the middle of the connecting rod.

[0018] Furthermore, the outer wall of the connecting rod, located on both sides of the fixing plate, is fixed with protrusions in a circular array.

[0019] Furthermore, a limiting hole is provided in the middle of the fabric strip, and a limiting rod that can move through the limiting hole is integrally formed on the connecting frame.

[0020] Furthermore: the shaped plate is fixed to the base plate by screws, and the connecting shell is fixed to the shaped plate by bolts.

[0021] This utility model provides a pipe loading hoist. Compared with the prior art, it has the following advantages:

[0022] 1. By setting up a shaping plate, connecting mechanism, fixing plate, cloth tape and clamping mechanism, the pipes are lifted and transferred to the vehicle after processing, so as to achieve the effect of horizontal lifting of the pipes. This replaces the method of manual winding and tightening, effectively avoiding the situation that the pipes will fall due to uneven force during the lifting process due to insufficient uniformity of multiple pipes, thus improving the safety of lifting.

[0023] 2. By setting the base, which includes a base plate and a telescopic rod, the two base plates can be moved closer or further apart along the two telescopic rods, and the distance between the two base plates can be adjusted. This allows for adjustment of the distance between the two plastic plates, so that when the pipe is hoisted and transferred, the distance between the two plastic plates can be adjusted according to the length of the pipe, making the hoisting of pipes of different lengths more stable.

[0024] 3. By using the design of limiting holes and limiting rods, the displacement range of the connecting frame outside the fabric tape is limited. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] Example 1

[0034] To address the technical problems in the background section, the following pipe loading hoist is provided:

[0035] Combination Figures 1-5 As shown, the present invention provides a pipe loading hoist, comprising:

[0036] Base 1;

[0037] Shaping plate 2, made of plastic sheet, two of them are arranged symmetrically on the top of base 1, and the middle part of the shaping plate 2 is fixed to base 1.

[0038] There are two sets of connecting mechanisms 3, which are symmetrically installed at both ends of the two plastic plates 2 on opposite sides.

[0039] A fixing plate 4 is rotatably mounted on a connecting mechanism 3. One fixing plate 4 has a cloth strip 5 fixedly connected to its top, and the other fixing plate 4 has a through hole 41.

[0040] The connecting frame 6 is movably sleeved on the outside of the fabric belt 5. The top of the connecting frame 6 has an integrally formed connecting ring 61, which is used to hook the hook 7. Specifically, the hook 7 is connected to the external overhead crane.

[0041] The snap-fit ​​mechanism 8 is installed at the other end of the fabric belt 5. The snap-fit ​​mechanism 8 can pass through the through hole 41 and snap-fit ​​with the fixing plate 4.

[0042] When using this lifting tool, it is placed next to the stack of pipes for hoisting, transferring, and loading. Workers move the pipes onto two shaping plates 2, placing them in the middle of the plates, ensuring both ends extend to the outer sides of the plates. After stacking, the fabric tape 5 is wrapped around the top of the pipes on the plates 2. Then, the clamping mechanism 8 passes through the perforation 41 on the fixing plate 4, engaging with the fixing plate 4. The fabric tape 5 is then secured by the two fixing plates 4. At this time, the connecting ring 61 is hooked to the hook 7. When the hook 7 is lifted by the external gantry crane, the connecting frame 6 is displaced outside the cloth belt 5 and drives the middle position of the cloth belt 5 to be lifted upward. Furthermore, through the two sets of connecting mechanisms 3, both ends of the two plastic plates 2 are deformed and bent upward, pulling the base 1 to move upward, thus achieving the effect of horizontally suspending the pipe. This replaces the method of manually winding and tightening, effectively avoiding the situation where multiple pipes are not tied evenly, which could cause the pipes to fall due to uneven force during the hoisting process, thereby improving the safety of hoisting.

[0043] Example 2

[0044] like Figures 1-5 As shown, based on the above embodiments, this embodiment further provides the following:

[0045] In this embodiment, the snap-fit ​​mechanism 8 includes a snap-fit ​​block 81 fixedly installed at the end of the fabric tape 5. The snap-fit ​​block 81 can pass through the through hole 41. A groove 811 is provided on the snap-fit ​​block 81. A snap-fit ​​plate 82 is hinged on the snap-fit ​​block 81 and located in the groove 811. A limiting plate 83 perpendicular to the snap-fit ​​plate 82 is integrally formed on the snap-fit ​​plate 82. When the end of the snap-fit ​​plate 82 extends into the through hole 41, the limiting plate 83 can abut against the fixed plate 4. When the free end of the snap-fit ​​plate 82 is located outside the snap-fit ​​block 81, the limiting plate 83 can move through the through hole 41. In use, the snap-fit ​​plate 82 is rotated on the snap-fit ​​block 81 so that the free end of the snap-fit ​​plate 82 is located outside the snap-fit ​​block 81. At this time, both the snap-fit ​​plate 82 and the snap-fit ​​block 81 pass through the through hole 41. By passing through the perforation 41, the groove 811 is positioned on the side of the fixing plate 4 away from the fabric belt 5. Then, the snap-fit ​​plate 82 is rotated to hide inside the groove 811. Pulling the fabric belt 5 causes the groove 811 on the snap-fit ​​block 81 to move into the perforation 41, thereby causing the end of the snap-fit ​​plate 82 to move into the perforation 41 and causing the limiting plate 83 to abut against the fixing plate 4. This achieves the snap-fit ​​and fixing state between the snap-fit ​​block 81 and the fixing plate 4, which is simple to operate. Conversely, by moving the groove 811 on the snap-fit ​​block 81 to the side of the fixing plate 4 away from the fabric belt 5 and rotating the snap-fit ​​plate 82 so that the free end of the snap-fit ​​plate 82 is located outside the snap-fit ​​block 81, the snap-fit ​​block 81 can be pulled out from the perforation 41, achieving the separation effect between the snap-fit ​​block 81 and the fixing plate 4, which is convenient to use.

[0046] In this embodiment, the base 1 includes two base plates 11, which are symmetrically arranged. Telescopic rods 12 are symmetrically fixedly installed on opposite sides of the two base plates 11. The two plastic plates 2 can be moved closer or further apart along the two telescopic rods 12 by two sets of connecting mechanisms 3. The two plastic plates 2 are respectively fixedly installed on the two base plates 11. By setting the base 1 to include base plates 11 and telescopic rods 12, the two base plates 11 can be moved closer or further apart along the two telescopic rods 12, and the distance between the two base plates 11 can be adjusted. In use, the two plastic plates 2 can be moved closer or further apart along the two telescopic rods 12 by two sets of connecting mechanisms 3, thereby adjusting the distance between the two plastic plates 2. Thus, when the pipe is hoisted and transferred, the distance between the two plastic plates 2 can be adjusted according to the length of the pipe, making the hoisting of pipes of different lengths more stable.

[0047] In this embodiment, the connecting mechanism 3 includes two connecting shells 31 respectively fixedly installed on opposite sides of the two molded plates 2. Each of the two connecting shells 31 has a threaded rod 32 threaded through it on its opposite side. Specifically, the threads on the two threaded rods 32 are in opposite directions, as shown below. Figure 3As shown, two threaded rods 32 are fixedly connected to a connecting rod 33 on opposite sides. The fixing plate 4 is rotatably installed in the middle of the connecting rod 33. In use, a rotational force is applied to the connecting rod 33, causing both threaded rods 32 to rotate around the connecting rod 33. Since the threads on the two threaded rods 32 are in opposite directions, the two plastic plates 2 are fixedly installed on the two base plates 11 respectively. At this time, the two base plates 11 move closer or further away from each other along the two telescopic rods 12, and the two connecting shells 31 move closer or further away from each other along the two threaded rods 32 respectively. This achieves the effect of making the two plastic plates 2 move closer or further away from each other along the two telescopic rods 12, which is convenient for operation.

[0048] Example 3

[0049] like Figures 1-5 As shown, based on the above embodiments, this embodiment further provides the following:

[0050] In this embodiment, the outer wall of the connecting rod 33 and both sides of the fixing plate 4 are fixed with protrusions 331 in a ring array. The design of the protrusions 331 increases the anti-slip properties of the surface of the connecting rod 33, which makes it easier for the operator to apply rotational force to the connecting rod 33 when rotating it.

[0051] In this embodiment, a limiting hole 51 is provided in the middle of the fabric strip 5, and a limiting rod 62 is integrally formed on the connecting frame 6, which moves through the limiting hole 51. Specifically, the limiting rod 62 can slide and move along the fabric strip 5 within the limiting hole 51. Through the design of the limiting hole 51 and the limiting rod 62, the displacement range of the connecting frame 6 outside the fabric strip 5 is limited. Furthermore, when the lifting device is moved into the vehicle compartment by an external gantry crane, after the base 1 is placed stably in contact with the compartment, the locking mechanism 8 and the fixing plate 4 are locked. At this time, the lifting device is lifted by the gantry crane, so that the base 1 gradually changes from a horizontal position to a vertical position, thereby causing the pipes stacked on the top of the two plastic plates 2 to slide down, achieving the effect of unloading the pipes stacked on the two plastic plates 2.

[0052] In this embodiment, the shaping plate 2 is fixed to the base plate 11 by screws, and the connecting shell 31 is fixed to the shaping plate 2 by bolts. The arrangement of fixing the shaping plate 2 to the base plate 11 by screws and the connecting shell 31 to the shaping plate 2 by bolts facilitates the installation and disassembly of the shaping plate 2, thereby facilitating the replacement of the shaping plate 2.
