Description

Technical Field

[0001] This utility model relates to a welding locking rotary lifting device, belonging to the technical field of pipe welding devices. Background Technology

[0002] The tube body is a circular tubular structural component. Tube bodies are frequently used in industrial production, including filling tube bodies, supporting structural tube bodies, and connecting structural tube bodies. Tube bodies often require end welding, which means that the tube body needs to be clamped and rotated to meet welding requirements.

[0003] Pipes come in various specifications, including differences in axial direction and diameter. During welding, the locking and rotating device must be compatible with pipes of different diameters and axial dimensions. Traditional devices typically combine a clamping mechanism, a rotating mechanism, and a lifting mechanism. The clamping mechanism holds and locks the pipe, the rotating mechanism drives the clamping mechanism, and the lifting mechanism drives the rotating mechanism's overall lifting. This type of device, which relies on the overall lifting of the rotating mechanism, is energy-intensive and struggles to achieve precise positional control of the pipe end. Furthermore, the inherent rotational displacement of the rotating mechanism makes it difficult to integrate an automated locking mechanism. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of the existing technology and to propose a welded locking rotary lifting device that addresses the problems of high energy consumption and difficulty in ensuring positional accuracy caused by traditional integral lifting drives.

The lifting power source includes a lifting slide with lifting displacement, and the lifting slide is provided with a movable connecting part that is connected to the lifting drive plate in a transmission manner. The lifting drive plate is circumferentially connected to the movable connecting part.

[0007] Preferably, the movable connecting part includes two movable mating blocks arranged at intervals, the two movable mating blocks having mating plates arranged opposite each other, and each of the mating plates having movable rollers arranged vertically at intervals for clamping the lifting drive carrier.

[0008] Preferably, the base body has a support frame at its bottom, and the support frame has a guide rail for slidingly engaging the lifting slide and a lifting drive source that is connected to the lifting slide.

[0009] Preferably, the base body is provided with a power source follow-up mechanism located at the end of the lifting drive plate opposite to the tube mounting mechanism. The power source follow-up mechanism includes a movable shaft plate and a plurality of power source pipes arranged on the movable shaft plate. The pipe body limiting part is provided with a power source docking pipe that corresponds to the power source pipe and is connected to the pipe body limiting part. A connecting hose is connected between any power source pipe and the corresponding power source docking pipe.

[0010] Preferably, the lifting guide column has a bearing end facing the tube mounting mechanism, and the bearing end is provided with a bearing limiting groove.

[0015] 2. Through the circumferential movement and axial follow-up design of the lifting mechanism, the lifting guide column and the rotating main shaft follow each other, which meets the requirements for lifting and adjusting the tube body and the follow-up coordination, and will not cause friction damage to the tube body.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0024] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in the present application can be combined with each other.

[0025] This utility model provides a welding-locking rotary lifting device, such as... Figures 1 to 6As shown, it includes a base body 1 and a rotating spindle 2 with rotational displacement mounted on the base body 1.

[0026] The top of the rotating spindle 2 is provided with a tube mounting mechanism 3 for mounting the tube body 100. The tube mounting mechanism 3 includes a mounting base 31 that is connected to the rotating spindle in a transmission manner. The top of the mounting base 31 is provided with a tube limiting part 311 for locking or releasing the tube body, and the bottom is provided with a tube carrier 312 having a loading channel 3120.

[0027] The base body 1 is provided with a lifting mechanism 4 at the bottom, which has lifting displacement. The lifting mechanism 4 includes a lifting shaft 41 that passes through the loading channel 3120 and a lifting power source 42 that is connected to the lifting shaft 41.

[0028] Detailed implementation process and principle explanation: When mounting the tube body 100, it is passed through the tube body limiting part 311 of the mounting base 31, so that its tube end passes through the loading channel 3120 and is supported on the lifting end of the lifting shaft 41. After adjusting the height of the free end of the tube body 100 by the lifting power source 42, the tube body is clamped and locked by the tube body limiting part 311.

[0029] At this time, the rotation of the main shaft 2 drives the rotation of the tube body 100, which satisfies the rotational welding requirements of its welding end.

[0030] In one specific embodiment, the lifting mechanism 4 includes a follower guide mechanism 5 disposed at the bottom of the rotating main shaft 2. The follower guide mechanism 5 includes a plurality of lifting guide columns 51 and a lifting drive plate 52 slidably connected to the plurality of lifting guide columns and drivenly connected to the lifting shaft.

[0031] The lifting power source 42 includes a lifting slide 421 with lifting displacement. The lifting slide 421 is provided with a movable connecting part 422 that is connected to the lifting drive plate 52 in a transmission manner. The lifting drive plate is circumferentially connected to the movable connecting part.

[0032] Specifically, the top rod of a traditional lifting mechanism will move relative to the circumferential direction of the tube, which will cause frictional damage to the tube. In this case, the design of the follow-up guide mechanism 5 is adopted, so that the lifting guide column 51 moves with the tube.

[0033] In detail, the lifting slide 421 is mounted on the base body 1. It drives the lifting drive plate 52 to move up and down through the movable connection part 422. The lifting drive plate 52 can rotate with the rotating spindle and move circumferentially and axially relative to the movable connection part 422. This allows the lifting guide column 51 and the tube to move together without lifting wear, making the rotation of the tube reliable and stable.

[0034] In one specific embodiment, the movable connection part 422 includes two movable mating blocks 4221 arranged at intervals. The two movable mating blocks have mating plates arranged opposite to each other. Each mating plate is provided with movable rollers 4222 arranged vertically at intervals for clamping the lifting drive plate.

[0035] This satisfies the requirements for circumferential movement and axial locking of the lifting drive platform.

[0036] Of course, other circumferential movement and axial locking connection methods can also be adopted, such as using a ring bearing. As long as the structure that satisfies the circumferential movement and axial locking of the lifting drive plate relative to the movable connection part 422 is within the protection scope of this case.

[0037] In one specific embodiment, the base body 1 has a support frame 10 at its bottom, and the support frame 10 has a guide rail for slidingly engaging with the lifting slide 421 and a lifting drive source 101 that is connected to the lifting slide in a transmission manner.

[0038] This satisfies the lifting drive requirements. Of course, a rotary motor or cylinder can also be used for screw drive to achieve the lifting displacement drive structure of the lifting slide 421.

[0039] In one specific embodiment, the base body 1 is provided with a power source follow-up mechanism 6 located at the end of the lifting drive plate 52 away from the tube body mounting mechanism. The power source follow-up mechanism includes a movable shaft plate 61 and a plurality of power source pipes 62 arranged on the movable circumferential plate. The tube body limiting part 311 is provided with a power source docking pipe that corresponds one-to-one with the power source pipe and is connected to the tube body limiting part. A connecting hose is connected between any power source pipe and the corresponding power source docking pipe.

[0040] Specifically, under normal circumstances, the pipe limiting part 311 uses a power source to achieve clamping, locking and loosening operations. However, due to the rotation of the rotating spindle, traditional connecting pipes may become entangled. In this case, a power source follow-up mechanism 6 is used to provide a power source path. The connecting hose will rotate with the movable shaft disk 61, thereby eliminating the problem of hose entanglement and thus realizing the power supply for the air or fluid medium path.

[0041] In one specific embodiment, the lifting guide column 41 has a bearing end facing the tube mounting mechanism, and the bearing end is provided with a bearing limiting groove 410.

[0042] It can achieve the limiting mounting of the tube end, meeting the stability requirements of relative load bearing.

[0043] In one specific embodiment, a rotational power source 102 is provided at the bottom of the base body 1, and the rotational power source is connected to the rotating main shaft through a transmission part.

[0044] The transmission part is generally a belt or gear, and other mechanisms that can realize torque transmission are also within the scope of protection of this case, thus satisfying the indirect rotation drive requirements of the rotating spindle.

[0045] In one specific embodiment, the tube mounting mechanism 3 includes a plurality of tube clamps 32 having radial opening and closing displacement, a drive cone sleeve 33 that is connected to the plurality of tube clamps in a transmission manner, and an axial drive power unit 34 for driving the axial displacement of the drive cone sleeve.

[0046] Specifically, the axial drive power unit 34 can drive the axial displacement of the drive cone sleeve 33, thereby driving the opening and closing displacement of the pipe clamp 32 and meeting the operational requirements for clamping or releasing the pipe body.

[0047] In one specific embodiment, the axial drive power unit 34 has a radially extending extension end 340, and the base body is provided with a position detection sensor 103 that cooperates with the extension end.

[0048] The position detection sensor 103 can monitor the position of the extension end 340, thereby enabling the monitoring of rotational displacement, monitoring of its operating cycle, and recording of welding cycle monitoring.

[0049] As described above, this invention satisfies the requirements for pipe locking and rotation drive, while also enabling pipe lifting height adjustment to meet welding position adaptation needs. The mounting and rotation lifting operations are efficient and smooth. Through the circumferential movement and axial follow-up design of the lifting mechanism, the lifting guide column and rotating main shaft move accordingly, meeting the requirements for pipe lifting drive adjustment and follow-up coordination, without causing frictional damage to the pipe. An automated locking and unlocking design is adopted, and a power source follow-up mechanism is designed to meet the supply requirements of gas or fluid media, preventing pipe entanglement.

[0050] The term "comprising" or any other similar term is intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus / device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent in such process, method, article, or apparatus / device.

[0051] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
