Description

Technical Field

[0001] This application relates to the field of pipeline hoisting technology, and in particular to a small pipeline hoisting auxiliary device. Background Technology

[0002] Small-scale pipeline hoisting auxiliary devices are an essential part of pipeline construction, and their design and construction methods are of great significance to ensuring the efficiency and cost-effectiveness of pipeline hoisting construction.

[0003] Currently, pipeline hoisting operations generally use cranes. However, the crane boom needs to have a large amount of rotation space, which leads to a decrease in hoisting efficiency when operating in narrow spaces. Utility Model Content

[0004] To solve or partially solve the problems existing in related technologies, this application provides a small-scale pipeline hoisting auxiliary device.

[0005] To achieve the above objectives, this application employs the following technical solution:

[0006] A small-scale pipe hoisting auxiliary device, the small-scale pipe hoisting auxiliary device comprising:

[0007] Load-bearing plate;

[0008] A lifting ring located on the lower end face of the middle part of the load-bearing plate;

[0009] Three detachable legs are attached to the lower outer perimeter of the load-bearing plate.

[0010] The three legs are arranged in a triangle to form a triangular support structure. The pipe is suspended below the lifting ring by a hoist and runs horizontally between the three legs.

[0011] Optionally, three pairs of connecting plates are fixed to the lower outer periphery of the load-bearing plate, and each pair of connecting plates is provided with bolt holes that match the bolts, so that the bolts can be inserted into the bolt holes.

[0012] Optionally, the upper part of the leg is connected to a bolt.

[0013] Optionally, the bolt is fixed and locked to the connecting plate by means of a nut.

[0014] Optionally, the axis of the foot rod is perpendicular to the axis of the bolt.

[0015] Optionally, the axis of the foot rod is parallel to the axis of the load-bearing plate.

[0016] Optionally, the load-bearing plate is circular or square.

[0017] The beneficial effects of this application are as follows: In traditional pipeline hoisting operations, the crane's boom requires a large amount of rotation space, which reduces hoisting efficiency when operating in confined spaces. However, this application utilizes a hoisting device consisting of a load-bearing plate, lifting rings, outriggers, and a hoist to replace the crane's boom, enabling the vertical hoisting of small pipelines without the need for a crane or rotation space for the boom. This reduces space occupation, avoids the limitations imposed by confined spaces on the hoisting of small pipelines, and ultimately improves the efficiency of pipeline hoisting in confined spaces.

[0029] To make the objectives, technical solutions, and beneficial effects of this application clearer, the preferred embodiments of this application will be described in detail below with reference to the accompanying drawings, so as to facilitate understanding by those skilled in the art.

[0030] Example 1:

[0031] See Figure 1 A small-scale pipe hoisting auxiliary device, the small-scale pipe hoisting auxiliary device comprising:

[0032] Load-bearing plate 1;

[0033] A lifting ring 4 is located on the lower end face of the middle part of the load-bearing plate 1;

[0034] Three detachable legs 5 are attached to the lower outer periphery of the load-bearing plate 1.

[0035] The three support poles 5 are arranged in a triangle to form a triangular support structure. The pipe is suspended below the lifting ring 4 by a hoist and runs horizontally between the three support poles 5.

[0036] Specifically, the load-bearing plate 1 bears the entire weight of the pipes and related auxiliary equipment (such as hoists, lifting ropes, etc.) transmitted through the lifting ring 4, and evenly distributes these concentrated loads to the three connecting legs 5. At the same time, it provides installation positions for the lifting ring 4 and the legs 5, ensuring that the lifting ring 4 is located on the lower end face of the middle part of the load-bearing plate 1, and the three legs 5 are evenly distributed on the lower end face of the outer periphery of the load-bearing plate, thus ensuring the stability of the entire device structure.

[0037] One end of the hoist is connected to the lifting ring 4, and the other end is connected to the pipe to be installed via a lifting rope. It transfers the pulling force generated by the hoist to the load-bearing plate 1, thereby enabling the lifting operation of the pipe. The lifting ring 4 is located on the lower middle surface of the load-bearing plate 1, providing an accurate positioning point for the pipe lifting. Simultaneously, it also plays a guiding role during the lifting process, ensuring the pipe rises or falls smoothly along the vertical direction. Furthermore, the hoist allows for adjustment of the pipe height, facilitating its installation.

[0038] The three support poles 5 are arranged in a triangle, forming a triangular support structure that provides stable support for the load-bearing plate 1 and the pipes on it. The support poles 5 distribute the weight transferred from the load-bearing plate 1 to the ground or other supporting surfaces, ensuring that the device will not tilt or collapse during hoisting. The limiting space formed between the support poles 5 can restrict the lateral movement of pipes inserted within, reducing lateral swaying during hoisting and improving the stability and accuracy of the hoisting. The support poles 5 are detachably connected to the load-bearing plate 1 for easy disassembly and replacement.

[0039] In traditional pipeline hoisting operations, the crane's boom requires a large amount of rotation space, which reduces hoisting efficiency when operating in confined spaces. However, this application utilizes a hoisting device consisting of a load-bearing plate 1, lifting ring 4, outriggers 5, and a hoist to replace the crane's boom, enabling the vertical hoisting of small pipelines. This eliminates the need for a crane and the need for boom rotation space, thereby reducing space requirements and preventing confined spaces from hindering the hoisting of small pipelines, ultimately improving the efficiency of pipeline hoisting in narrow spaces.

[0040] Example 2:

[0041] See Figure 1 Based on Embodiment 1, optionally, three pairs of connecting plates 3 are fixed on the lower outer periphery of the load-bearing plate 1, and each pair of connecting plates 3 is provided with bolt holes that match the bolts 2, so that the bolts 2 can be inserted into the bolt holes.

[0042] Specifically, each pair of connecting plates 3 includes two connecting plates 3 with a gap between them to accommodate the upper part of the foot rod 5. The upper end of the connecting plate 3 is welded to the lower outer surface of the load-bearing plate 1 to enhance the structural strength and rigidity, thereby extending the service life. The bolt 2 is threaded into the bolt hole on the connecting plate 3 to facilitate the replacement of the connecting parts.

[0043] Optionally, the upper part of the foot rod 5 is connected to the bolt 2.

[0044] Specifically, the upper part of the leg 5 is connected to the bolt 2 so that the leg 5 supports the load-bearing plate 1; at the same time, the leg 5 is detachably connected to the connecting plate 3 by the bolt 2, which facilitates the replacement of the leg 5.

[0045] Optionally, the bolt 2 is fixed and locked to the connecting plate 3 by means of a nut.

[0046] Specifically, tighten the nut to fix the bolt 2 to the connecting plate 3, thereby installing the upper part of the foot rod 5 at the connecting plate 3, loosen the nut to separate the bolt 2 from the connecting plate 3, and thus remove the foot rod 5.

[0047] Optionally, the axis of the foot rod 5 is perpendicular to the axis of the bolt 2.

[0048] Specifically, the vertical arrangement ensures that when bolts 2 are tightened, the force is applied perpendicularly to the support rod 5, effectively limiting the rotation of the support rod 5 around the axis of bolts 2, preventing loosening of the connection, and ensuring the reliability of the structural connection. The vertical structure also allows the load borne by the support rod 5 (such as the weight of the pipeline) to be transferred more evenly to the main body (such as the top load-bearing plate 1) through bolts 2, avoiding stress concentration and improving the overall mechanical performance of the structure.

[0049] Optionally, the axis of the foot rod 5 is parallel to the axis of the load-bearing plate 1.

[0050] Specifically, the load borne by the load-bearing plate 1 can be transmitted vertically along the axis of the leg 5, so that the force direction of each leg 5 is consistent and the distribution is balanced, avoiding local stress concentration and extending the service life of the structure; the parallel layout ensures that the overall support system is perpendicular to the load-bearing plate 1, reducing structural offset or swaying caused by the tilting of the leg 5, and maintaining a stable load-bearing posture.

[0051] Optionally, the load-bearing plate 1 is circular or square.

[0052] Specifically, the shape and size design of the load-bearing plate 1 are crucial for maintaining the stability of the device. Generally, using a disc-shaped or near-circular load-bearing plate 1 allows the three legs 5 to be evenly distributed around its perimeter, forming a stable support structure. Using a square shape, with its right-angled sides serving as a direct installation reference, simplifies the positioning and fixing of connecting parts such as bolts 2, and facilitates alignment and calibration during construction.

[0053] In addition, in this application, the load-bearing plate 1 can be cut, welded, and installed on-site, while the connecting plate 3, lifting ring 4, and foot rod 5 can all be prefabricated. When the pipeline hoisting construction is to be carried out, the load-bearing plate 1, bolts 2, connecting plate 3, lifting ring 4, and foot rod 5 can be assembled on-site, and the pipeline hoisting construction can then be carried out.

[0054] It should be noted that the structures and / or installation methods not detailed in this application are those that can be known by those skilled in the art in combination with common knowledge and / or prior art, and are not the focus of this application, and will not be elaborated further here.

[0055] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this application; the dimensions of the drawings are not related to the specific physical object, and the physical object dimensions can be arbitrarily changed.
