Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and more specifically, to a pipeline hoisting device. Background Art

[0002] In the prior art, the lifting of pipelines is mainly achieved through lifting belts. During construction, the pipeline needs to be lifted and raised, and the lifting belt is passed around the bottom of the pipeline. Since the pipeline needs to be lifted and raised, there are certain safety risks and the installation efficiency is low. After the pipeline is lifted to the designated position, the lifting belt is difficult to be directly withdrawn. Usually, the pipeline needs to be lifted to remove the lifting belt, which may cause the axis of the pipeline to deviate from the designed position and require repeated adjustments, resulting in a long construction period and high cost.

[0003] In addition, the contact area between the lifting belt and the pipeline is small, which causes the force on the pipeline to be concentrated at the contact position, which can easily cause the pipeline to deform or even be damaged.

[0004] In summary, how to safely and conveniently realize the lifting of pipelines is a problem that needs to be urgently solved by technical personnel in this field. Utility Model Content

[0005] In view of this, the purpose of the utility model is to provide a pipeline lifting device with a simple structure, convenient operation and high safety. During the lifting process, the pipeline is subjected to uniform force, the pipeline can be accurately positioned, and the lifting quality and lifting efficiency are high.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A pipeline hoisting device, comprising:

[0008] At least two hanging components, the hanging components comprising two clamping rods for clamping the pipe, the two clamping rods being cross-connected by a pin;

[0009] A connecting rod, used to connect the clamping rods on the same side of two adjacent lifting components;

[0010] A lifting ring, used for connecting with the lifting equipment, and arranged on the connecting rod;

[0011] The limiting rod has two ends which are detachably connected to the connecting rods or the hanging rings on both sides, and is used to limit the opening angle of the two clamping rods.

[0012] Preferably, when the clamping rod clamps the pipe, an angle α between a line connecting the lower edge of the clamping rod and the center of the pipe and the axis of symmetry of the pipe satisfies: 30°≤α≤60°.

[0013] Preferably, the connecting rod is connected to the upper edge of the clamping rod by welding.

[0014] Preferably, the lifting ring is welded at the midpoint of the connecting rod.

[0015] Preferably, both ends of the limiting rod are provided with a through hanging ring installation groove (41), and the hanging ring is clamped in the hanging ring installation groove (41).

[0016] Preferably, the clamping rod is provided with an anti-skid layer, and the anti-skid layer is used to increase the friction between the clamping rod and the pipeline.

[0017] Preferably, the outer surface of the anti-slip layer is provided with an anti-slip structure, and the anti-slip structure includes an anti-slip groove, anti-slip protrusions and an anti-slip pattern.

[0018] Preferably, the limiting rod is a telescopic rod with adjustable length.

[0019] Preferably, the telescopic rod comprises a telescopic rod body and a sleeve sleeved outside the telescopic rod body, one of the telescopic rod body and the sleeve is provided with a bolt connection hole, and the other is evenly provided with a plurality of bolt mounting holes along the extension direction.

[0020] When in use, first control the two clamping rods of the lifting component to move away from each other, and place the pipe to be lifted between the two clamping rods; then control the two clamping rods of the lifting component to move closer to each other, so that the clamping rods clamp the pipe to be lifted; then connect the limit rods to the connecting rods or lifting rings on both sides, and use the limit rods to fix the opening angle of the two clamping rods; finally connect the lifting ring and the lifting equipment to lift the pipe into place.

[0021] After the lifting is in place, the limit rod is removed, and the two clamping rods of the lifting component are controlled to move away from each other, so that the clamping rods are separated from the pipeline and the lifting device is removed.

[0022] The pipe hoisting device provided by the utility model has a contact area between the clamping rod of the hoisting component and the pipe, which is much larger than the contact area between the existing hoisting belt and the pipe, thereby alleviating the stress concentration problem during pipe hoisting, making the pipe force relatively uniform, avoiding deformation or even damage of the pipe during the hoisting process, and achieving high hoisting quality;

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] The core of the utility model is to provide a pipeline hoisting device with simple structure, convenient operation and high safety. During the hoisting process, the pipeline is evenly stressed, and the pipeline can be accurately positioned, with high hoisting quality and hoisting efficiency.

[0033] It should be noted that the lifting ring 3 in the present application document not only includes a lifting ring, but also includes a lifting hook, a lifting ear and other lifting connectors for cooperating with the lifting equipment.

[0034] The pipeline hoisting device provided by the utility model comprises:

[0035] At least two hanging components 1, the hanging components 1 include two clamping rods 11 for clamping the pipe 01, and the two clamping rods 11 are cross-connected by a pin 12;

[0036] A connecting rod 2, used to connect the clamping rods 11 on the same side of two adjacent lifting components 1;

[0037] A lifting ring 3, used for connecting with a lifting device, and arranged on the connecting rod 2;

[0038] The limiting rod 4 has two ends detachably connected to the connecting rods 2 or the lifting rings 3 on both sides, and is used to limit the opening angle of the two clamping rods 11.

[0039] Among them, the lifting component 1 is used to clamp the pipe 01 to be lifted. Considering that the length of the pipe 01 is about 2m, setting only a single lifting component 1 not only requires high structural strength of the lifting component 1, but also makes it difficult to maintain the balance of the pipe 01 during lifting. Therefore, the number of lifting components 1 is set to two, and the two lifting components 1 are respectively arranged at the two ends of the length direction of the pipe 01 to be lifted.

[0040] Of course, the number of hanging components 1 can be increased as appropriate according to the length of the pipeline 01. When the number of hanging components 1 is greater than or equal to 3, the distance between any two hanging components 1 can be set to be the same, that is, the lengths of any two connecting rods 2 connecting two adjacent hanging components 1 are the same.

[0041] The two clamping rods 11 of the hanging component 1 are connected by a pin 12, so that the hanging component 1 is a nearly X-shaped connecting rod structure. By adjusting the opening angle of the two clamping rods 11, the hanging component 1 can clamp and release the pipe 01.

[0042] Please refer to Figure 1 The clamping rod 11 includes a straight rod section and an arc section for clamping the pipe 01. The pin 12 is usually arranged at 1 / 2 or 1 / 3 of the height of the straight rod section. The radius of the arc section is determined according to the diameter of the pipe 01 to be hoisted.

[0043] In order to prevent the two clamping rods 11 from interfering with each other, and to avoid the clamping rod 11 from being inserted into the bottom end of the pipe 01 and affecting the loading and unloading of the lifting component 1, the angle α between the line connecting the lower edge of the clamping rod 11 and the center of the pipe 01 and the axis of symmetry of the pipe 01 should be greater than 0°; at the same time, in order to enable the clamping rod 11 to clamp the pipe 01, the above angle α should be less than 90°.

[0044] The size of the angle α will affect the shape and size of the lower edge of the clamping rod 11. The smaller the angle α is, the closer the clamping rod 11 is to the lowest point of the pipe 01 in the clamped state, and the higher the processing requirements for the lower edge of the clamping rod 11 are.

[0045] Preferably, when the clamping rod 11 clamps the pipe 01, the angle α between the line connecting the lower edge of the clamping rod 11 and the center of the pipe 01 and the symmetry axis of the pipe 01 satisfies 30°≤α≤60°. This can not only effectively clamp the pipe 01 and provide strong clamping stability, but also prevent the clamping rod 11 from being inserted into the bottom end of the pipe 01, facilitate loading and unloading, and facilitate processing of the lower edge of the clamping rod 11.

[0046] In order to reduce the number of lifting points and facilitate lifting, two adjacent lifting components 1 are connected by a connecting rod 2 to form an integrated structure. The connecting rod 2 and the lifting component 1 can be connected by a detachable method such as bolt connection, pin connection, etc., or by a non-detachable method such as welding. The two can also be set as an integrated structure.

[0047] Taking into account the convenience of obtaining materials and the cost, the clamping rod 11 of the lifting component 1 is mostly formed by bending a square steel pipe, and the connecting rod 2 is mostly set as a square steel pipe, and the connecting rod 2 is welded to the upper edge of the clamping rod 11.

[0048] The lifting ring 3 is arranged on the connecting rod 2 and is used to connect the lifting device and the lifting equipment; the lifting ring 3 can be arranged on the upper end surface of the connecting rod 2, or on the side surface of the connecting rod 2, but it should be noted that when the lifting ring 3 is arranged on the side surface of the connecting rod 2, the lifting hole of the lifting ring 3 still needs to be partially higher than the upper end surface of the connecting rod 2.

[0049] In order to make the force of the lifting device relatively balanced, the lifting ring 3 is usually welded to the midpoint of the connecting rod 2; the specific material, structure and size of the lifting ring 3 are determined according to factors such as the type of lifting equipment in actual production and the quality of the pipeline 01, and will not be repeated here.

[0050] The limit rod 4 is arranged between the connecting rods 2 on both sides, and the two ends of the limit rod 4 are detachably connected to the connecting rods 2 or the lifting rings 3 on both sides. The limit rod 4 can limit the horizontal distance between the two connecting rods 2 and the opening angle of the two clamping rods 11.

[0051] The limiting rod 4 and the connecting rod 2, or the limiting rod 4 and the lifting ring 3, can be connected by common connecting parts such as fastening bolts and connecting pins, or can be connected by a clamping method; in order to facilitate the disassembly and assembly of the limiting rod 4, preferably, both ends of the limiting rod 4 can be provided with a through lifting ring mounting groove 41, and the lifting ring 3 can be clamped in the lifting ring mounting groove 41, such as Figure 3 shown.

[0052] When in use, first control the two clamping rods 11 of the lifting component 1 to move away from each other, and place the pipe 01 to be lifted between the two clamping rods 11; then control the two clamping rods 11 of the lifting component 1 to move closer to each other, so that the clamping rods 11 clamp the pipe 01 to be lifted; then connect the limit rod 4 with the connecting rods 2 or the lifting rings 3 on both sides, and use the limit rod 4 to fix the opening angle of the two clamping rods 11; finally, connect the lifting ring 3 and the lifting equipment to lift the pipe 01 into place.

[0053] After the lifting is in place, the limit rod 4 is removed, and the two clamping rods 11 of the lifting component 1 are controlled to move away from each other, so that the clamping rods 11 are separated from the pipeline 01, and the lifting device is removed.

[0054] In this embodiment, the contact area between the clamping rod 11 of the hoisting member 1 and the pipe 01 is much larger than the contact area between the existing hoisting belt and the pipe 01, which alleviates the stress concentration problem during the hoisting of the pipe 01, makes the force on the pipe 01 relatively uniform, avoids deformation or even damage of the pipe 01 during the hoisting process, and has high hoisting quality;

[0055] There is no need to lift or raise pipe 01 during hoisting. It is easy to operate and highly safe. The position of pipe 01 will not be affected when the hoisting device is dismantled, so the precise positioning of pipe 01 is achieved. There is no need to repeatedly adjust the position of pipe 01, which effectively improves the hoisting efficiency.

[0056] On the basis of the above embodiment, in order to prevent the pipe 01 from being separated from the hanging component 1 , the clamping rod 11 may be provided with an anti-skid layer, and the anti-skid layer is used to increase the friction between the clamping rod 11 and the pipe 01 .

[0057] The anti-slip layer can be set as a rubber anti-slip cover, an anti-slip coating, etc. The specific material, structure and size of the anti-slip layer are determined according to the actual production needs and refer to the existing technology, and will not be repeated here.

[0058] When the anti-slip layer is set as a rubber waterproof cover, preferably, the outer surface of the anti-slip layer can be provided with an anti-slip structure, the anti-slip structure includes anti-slip grooves, anti-slip protrusions and anti-slip patterns, etc., to further increase the friction between the clamping rod 11 and the pipe 01.

[0059] The shape, size and distribution of the anti-skid grooves, the shape, size and distribution of the anti-skid protrusions, and the type, size and distribution of the anti-skid patterns are determined according to the needs of actual production and with reference to the prior art, and will not be elaborated here.

[0060] On the basis of the above embodiment, the limit rod 4 can be set as a telescopic rod with adjustable length. The length of the limit rod 4 can be adjusted according to the diameter of the pipe 01 to be hoisted, avoiding the replacement of limit rods 4 of different lengths, which is beneficial to saving costs and improving the applicability of the hoisting device.

[0061] Preferably, the telescopic rod comprises a telescopic rod body and a sleeve sleeved outside the telescopic rod body, one of the telescopic rod body and the sleeve is provided with a bolt connection hole, and the other is evenly provided with a plurality of bolt installation holes along the extension direction. The length of the telescopic rod can be adjusted by adjusting the installation position of the connection bolt, which has a simple structure, low processing cost, and convenient adjustment.

[0062] Of course, the limit rod 4 can also be replaced by a telescopic cylinder, an electric push rod and other structures. Taking the telescopic cylinder as an example, the fixed end of the telescopic cylinder and the lifting ring mounting groove 41 can be set, and the end of the piston rod is connected to another lifting ring mounting groove 41, and the length of the telescopic cylinder is adjusted by the extension and contraction of the piston rod.

[0063] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0064] The above is a detailed introduction to the pipe lifting device provided by the utility model. This article uses specific examples to illustrate the principle and implementation method of the utility model. The description of the above embodiments is only used to help understand the method and core idea of ​​the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
