Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to an intelligent synchronous lifting and welding device. Background Art

[0002] The quality and efficiency of pulp and paper related products are increasing day by day, and the application value of pulp and paper machinery and equipment is becoming increasingly prominent. The installation of pulp and paper professional equipment has extremely strict precision requirements. In order to better display the actual application value of the equipment, it is necessary to improve the installation quality and precision of the equipment, so as to better improve the operation status and application value of pulp and paper equipment.

[0003] Installing equipment requires connecting multiple steps such as establishing a reference line, installing a base plate, assembling a dryer section, a press section, a Fourdrinier section, assembling a calender, a reel, and a drive section, commissioning and acceptance, etc., which constitutes the installation process of pulp and paper equipment. Among them, the quality of the installation of pulp professional equipment involves precise lofting measurement control, embedded and buried precision control, welding control, and lifting precision control, etc. Each link is closely linked to ensure the accuracy, stability and safety of the entire equipment installation process.

[0004] Currently, on-site hoisting construction and welding of equipment are still carried out manually. It requires skilled hoisting personnel to operate the hoisting equipment stably and perform manual fine welding to ensure stable cooperation between hoisting and welding operations. When welding manually, it is necessary to stably position the welded parts hoisted in the upper section and then weld. During the welding process, the welded parts hoisted will swing due to welding operations and support. This welding process is a dynamic operation process. Especially, the force between the welded parts and the fixed parts changes in real time. As the welding joint continuously closes and the connection relationship gradually tends to a stable connection, the force relationship of hoisting will change significantly. At this time, the hoisting force needs to change with the change of the welding gap, and the force application method and angle will also shift.

[0005] Based on this, the utility model designs an intelligent synchronous lifting and welding device to solve the above problems. Summary of the Utility Model

[0006] The purpose of the utility model is to provide an intelligent synchronous lifting and welding device. The device can generate the on-site welding position relationship through laser scanning, and compare the size data through the device to obtain the welding points and data for the welding arm, which is convenient for automatic welding. It can conveniently and accurately determine the equipment hoisting points and hoisting sequence. The device also adds four lifting ropes, on which stress detectors are arranged, which can real-time monitor the stress conditions of the welded parts hoisted in multiple directions, and timely adjust the stress conditions of each direction of the welded parts through the rope winder to ensure the hoisting stability during the welding process, facilitate stable welding, and avoid the situation of uneven stress after welding.

[0007] The present utility model is implemented as follows: An intelligent synchronous lifting and welding device, comprising:

The regulating cables are all suspended below the balance suspension plate, and a load-bearing hook is provided at the lower end of each regulating cable.

[0015] A stress detector is provided on each of the regulating cables;

[0016] A controller is provided on the crane truck, and the rope winder, the stress detector, the lifting boom and the welding arm are all connected to the controller.

[0017] Further, a plurality of suspension ropes are provided at the top of the balance suspension plate, and the balance suspension plate is stably suspended on the lifting hook through the plurality of suspension ropes;

[0018] The horizontal detector is provided at the center of the balance suspension plate.

[0020] The lower end of the regulating cable extends below the balance suspension plate with a fixed position through a pulley, and the upper end of the regulating cable is wound on the rope winder;

[0033] In a specific embodiment of the technical solution of the present utility model:

[0034] It includes a crane truck 1, a balance suspension plate 2, a rope winder 3, a lifting boom 4 and a welding arm 5;

[0035] A laser scanner 11 is provided on the crane truck 1, and a plurality of hydraulic outriggers 12 are also provided around the crane truck 1. The crane truck 1 is stably supported by the hydraulic outriggers 12 to facilitate welding and lifting operations; the laser scanner 11 is provided at the front end of the crane truck 1; a camera is also provided on the automatic welding machine 51, and the welding end of the automatic welding machine 51 is within the shooting range of the camera, which can conveniently observe the welding situation, as well as the welding angle and position.

[0036] Both the lifting boom 4 and the welding arm 5 are provided on the crane truck 1. One crane truck 1 can complete welding and lifting tasks by itself, which is more flexible to use and occupies less construction site.

[0037] The lifting boom 4 is above the welding arm 5; the lifting boom 4 is a hydraulic lifting boom, and the welding arm 5 is a multi-axis robotic arm.

[0038] A lifting hook 41 is provided at the front end of the lifting boom 4, and an automatic welding machine 51 is provided at the front end of the welding arm 5;

[0039] The balance suspension plate 2 is a square flat plate, and the balance suspension plate 2 is stably horizontally hung on the lifting hook 41 at the front end of the lifting boom 4; a plurality of suspension ropes 22 are provided on the top of the balance suspension plate 2, and the balance suspension plate 2 is stably hung on the lifting hook 41 through the plurality of suspension ropes 22;

[0040] A horizontal detector 21 is provided at the center of the balance suspension plate 2, and the horizontal detector 21 is an electronic level sensor or a universal level. It can ensure that the balance suspension plate 2 remains horizontal and provides a stable platform during lifting.

[0041] A horizontal detector 21 is provided on the balance suspension plate 2;

[0042] The rope winder 3 is an electric rope winder. A plurality of rope winders 3 are evenly distributed on the balance suspension plate 2. A regulating cable 31 is wound on each of the rope winders 3. The regulating cables 31 are all hung below the balance suspension plate 2, and a load-bearing hook 33 is provided at the lower end of each regulating cable 31. There are four rope winders 3, and the four rope winders 3 are distributed in a square on the balance suspension plate 2;

[0043] The lower end of the adjusting cable 31 extends below the balance suspension plate 2 with its position fixed by a pulley, and the upper end of the adjusting cable 31 is wound around the rope winder 3;

[0044] The adjusting cable 31 is a steel wire rope.

[0045] A stress detector 32 is provided on each adjusting cable 31;

[0046] A controller is provided on the crane 1, and the rope winder 3, the stress detector 32, the lifting boom 4 and the welding arm 5 are all connected to the controller.

[0047] It should be noted that:

[0048] 1. For larger equipment, during welding, it is necessary to first spot-weld and position the four sides, fix it to a certain extent, then release the lifting equipment, and then perform full welding. This operation has relatively high requirements for welders. Moreover, when spot-welding at each point, it is necessary to ensure that the welded parts being lifted remain stable. When the welded parts are lifted, they are in a hovering state when not welded, and during the welding process, the welding points are in a connected state while other parts are in a suspended state, and the force will change, resulting in possible skew of the welding seams and uneven stress, which is also the operation difficulty of lifting and welding. This device hoists the welded parts through the rope winders 3 at the four points, detects the hoisting force at each point through the stress detectors 32, and adjusts the force of the adjusting cable 31 by winding or stretching the rope winder 3, and keeps the force at each point uniform, so as to maintain stable welding. There are stress detectors 32 on all four adjusting cables 31, which can automatically adjust the force in a timely manner to ensure the stable hoisting of the welded parts and the stability during welding construction; 2. When the current equipment is hoisted, it requires manual hoisting and fine adjustment by humans to ensure the stability of the welded parts. However, the welded parts all need to be hoisted by steel wire ropes through devices such as hanging ears, and can only be hoisted at multiple points, without adjustment of the horizontal attitude of the welded parts during hoisting, which is inconvenient to operate. This device also adds a horizontal detector 21, which can monitor in real time whether the balance suspension plate 2 is horizontal, and adjust the force and hoisting force in a timely manner to ensure uniform and stable welding; 3. At present, the welding at the construction site depends on experienced welders. The higher the welding precision required for the equipment, the greater the welding difficulty. Manual welding has certain limitations and it is also difficult to have an overall view of the hoisting and welding situation of large equipment. This device can preset and plan the route, weld the equipment structure in sequence, perform automated welding through the flexible adjustment of the automatic welding machine 51 and the welding arm 5, and scan and analyze the welding seams through the laser scanner 11, making the welding operation more automated and the welding more stable.

[0049] When the utility model is in use, the crane 1 is driven to the construction site and stably supported by the hydraulic outriggers 12. The fixing parts and welding parts are scanned by the laser scanner 11 to obtain the equipment contour data. Generally, the BIM data of the welding points are scanned, and the data are compared to determine the hoisting points and hoisting sequence of the welding equipment.

[0050] Initially, the balance lifting plate 2 is locked on the lifting hook 41 through the lifting rope 22 and the buckle. The horizontal detector 21 is used to ensure that the balance lifting plate 2 is in a horizontal state. Then the welding part is hoisted and hung on the load-bearing hook 33 to ensure stability. Then the retractable cable 31 is adjusted by the cable winder 3 to lift the welding part and make it reach a horizontal state. At the same time, the stress detector 32 on the adjusting cable 31 is used to balance the multi-point forces of the welding part to ensure stable force, and the welding part is hoisted to the welding position.

[0051] The welding points are welded by the automatic welding machine, and the welding angle is controlled by the welding arm 5 made of the multi-axis robotic arm, making the welding more accurate and rapid, the weld seams more balanced, and the welding more firm.

[0052] Although the specific implementation manners of the utility model are described above, those skilled in the art of this technology should understand that the specific embodiments we described are illustrative rather than used to limit the scope of the utility model. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the utility model should be covered by the scope protected by the claims of the utility model.
