Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and more particularly to a mobile welding device. Background Technology

[0002] In fields such as equipment maintenance, electric welding is a common construction procedure. During electric welding operations, welding machines, welding rods, cables, gas cylinders, and fire-fighting equipment need to be moved and placed separately, which presents the following problems: First, the equipment is scattered, making it time-consuming and labor-intensive to move, affecting work efficiency; second, cables, welding rods, etc. are easily confused, making management difficult; third, there is a lack of standardized integrated management on site (disorganized cables can easily cause electric shock, and there are no nearby fire-fighting facilities for electric welding operations), posing safety hazards.

[0003] To address the aforementioned issues, existing technologies typically integrate welding equipment (welding components), consumables, and fire-fighting devices onto a mobile cabinet-type trolley. When welding operations are required, the cabinet-type trolley is pushed to the target work area, facilitating management, improving work efficiency, and reducing operational hazards.

[0004] While the above solution is beneficial for welding equipment management and safe operation, the cabinet-type trolley has poor maneuverability due to its large size, low chassis, and the large number of items it needs to carry.

[0005] The actual work site environment is complex, especially when performing equipment maintenance welding. Sometimes it is necessary to cross production lines, cross dense pipelines, or work in small spaces. The cabinet-type trolley carrying gas cylinders is difficult to approach the target work position due to obstacles. In addition, production specifications require that gas cylinders be at least 5 meters away from the welding work position (open flame point). Therefore, when working, the cabinet-type trolley needs to be parked near the target work position, and the welding machine, consumables, and fire-fighting equipment need to be moved to the target position while simultaneously laying cables and gas pipes. When laying cables and gas pipes, it is necessary to avoid scattering and avoid small-area large-angle bends in the cables and gas pipes (pipelines). At the same time, it is also necessary to perform heat insulation, wear prevention, and cut prevention treatment on local parts of the pipelines according to the actual site environment, so that the pipelines can be damaged due to contact with heat sources or wear and tear during welding (gas leakage, electric shock, etc.), which would seriously affect the safe conduct of welding operations.

[0006] Therefore, there is a need for a mobile welding device that is flexible and convenient to use, can assist operators in moving and organizing components and materials, can help operators easily enter complex work scenarios (production lines, pipe gaps, equipment interiors, equipment gaps, etc.) to perform welding operations, is not prone to pipe entanglement during use, is easy to retrieve after pipe deployment, can automatically protect pipes and is not prone to bending or damage during use, and has high safety.

[0070] Example 1

[0071] like Figures 1 to 6 As shown, the mobile welding apparatus of this application includes a base vehicle 100, a mobile vehicle 200, a pipeline reel assembly, a cable management assembly, and a protective belt arrangement assembly.

[0072] The basic carrier 100 is a cabinet-type trolley with a handle on the top and multiple universal wheels with braking function on the bottom, which serves to carry containers.

[0073] Furthermore, the basic carrier vehicle 100 includes a base plate 110 and a plurality of storage compartments 130 positioned on the base plate 110; the base plate 110 is a horizontally placed rigid plate; the storage compartments 130 are frame structures or box structures.

[0074] The mobile carrier 200 is also a cabinet-type trolley with casters at the bottom and one or more handles at the top, serving to carry containers while ensuring its own mobility; the volume of the mobile carrier 200 is less than one-quarter of the volume of the basic carrier 100, making it easy for operators to carry by hand.

[0075] Furthermore, the mobile carrier 200 includes a base plate 210, a support frame 220, a winding bracket 221, and a top handle 222. The base plate 210 is a horizontally placed rigid plate with casters at the bottom. The support frame 220 is a frame structure made of rigid material, fixed to the base plate 210, forming a rectangular block space on the base plate 210. The winding bracket 221 is a horizontally placed rigid rod with one end raised. The non-raised end is fixed to the side wall of the support frame 220 near the top. There are two or more of these, used to provide a support for collecting the cable. When retrieving the cable, the cable can be wound multiple times on the winding bracket 221 for temporary storage. The top handle 222 is fixed to the top of the support frame 220 near the center and / or near the side for easy gripping.

[0076] The mobile carrier 200 carries some consumables, welding machines, light fire-fighting equipment, protective equipment, etc., while the base carrier 100 carries gas cylinders, power supplies, other fire-fighting equipment, air hose reels, and cable reels, etc. The mobile carrier 200 is normally placed on top of the base carrier 100.

[0077] The main body of the pipeline reel assembly is a combination of multiple reels, positioned on the top of the base plate 110, including a reel carrier 310, a cable reel 320, a hose reel 330, and a fixed carrier 340.

[0078] The reel carrier 310 is a vertical rigid frame, and there are one or more of them, which are fixed to the top of the base plate 110.

[0079] Both the cable reel 320 and the hose reel 330 are reel structures, with their axial direction parallel to the horizontal ground, suspended in mid-air, and positioned on the reel carrier 310. They are used to wind and store the power transmission cable 321 and the connecting hose 331, respectively. The cable reel 320 and the hose reel 330 are controlled to rotate and lock with the reel carrier 310, thereby enabling the on-demand winding and unwinding of the pipelines. One end of the power transmission cable 321 is fixed to the cable reel 320 and connected to the power source, and one end of the connecting hose 331 is fixed to the hose reel 330 and connected to the gas cylinder. The connection position between the cable reel 320 and the hose reel 330 and the reel carrier 310 is equipped with a ratchet self-locking automatic winding mechanism or a clutch self-locking retraction mechanism.

[0080] The fixed frame 340 is a rigid frame or rigid plate, fixed to the bottom plate 210 of the mobile vehicle 200 near one edge; the other ends of the power transmission cable 321 and the connecting hose 331 are both fixed to the fixed frame 340; the electrical equipment and gas equipment on the mobile vehicle 200 are connected to the power transmission cable 321 and the connecting hose 331 respectively.

[0081] The ratchet self-locking automatic winding mechanism is a combination of a ratchet and pawl mechanism and a coil spring. When the cable is pulled, the ratchet rotates with the reel, and the coil spring accumulates elastic potential energy. When the cable is released, the pawl locks the reel. When it is time to recycle, the cable is pulled to disengage the pawl from the ratchet's teeth, and then the cable is released to achieve automatic winding and recycling with the help of the coil spring's elasticity.

[0082] The clutch-type self-locking retraction mechanism is a combination of a button, a ratchet and pawl mechanism, and a coil spring. Pressing the button allows the reel to rotate, and releasing the button locks the rotation of the reel. When the reel needs to release the cable, the reel is rotated by pulling the cable, which allows the coil spring to accumulate elastic potential energy. When the cable needs to be wound up, simply pressing the button to unlock the turntable allows the coil spring to release its elastic potential energy and drive the reel to rotate.

[0083] Preferably, the component for pressing the control button is a telescopic electric actuator controlled by a remote control.

[0084] The structure in which the power transmission cable 321 is connected to the power source via the cable reel 320, the structure in which the connecting hose 331 is connected to the gas cylinder via the hose reel 331, the ratchet self-locking automatic winding mechanism and the clutch self-locking retraction mechanism are all existing technologies and will not be described in detail here.

[0085] The cable management assembly is used to guide the direction of the power transmission cable 321 and the connecting hose 331. It is located between the reel carrier 310 of the cable reel assembly and the top reel 540 of the protective belt arrangement assembly, and is positioned on the top of the base plate 110 of the base vehicle 100. It includes a side support column 410, a top guide roller 420 and a bottom guide roller 430.

[0086] The side support column 410 is a vertical rigid frame, there are two of them, and the bottom is fixed on the base plate 110, which serves to bear the load and provide support.

[0087] The top guide roller 420 and the bottom guide roller 430 are both horizontally placed rigid rollers, one above the other, and both ends are rotatably connected to the two side support columns 410.

[0088] The power transmission cable 321 and the connecting hose 331 pass between the top guide roller 420 and the bottom guide roller 430, and the two rollers guide and restrain the pipeline.

[0089] like Figures 4 to 6 As shown, the protective belt arrangement assembly is used to automatically set a protective sleeve for the pipeline extending from the base vehicle 100, reducing the probability of entanglement and wear. It includes a vertical stand 510, a top combination belt 520, a bottom combination belt 530, a top belt drum 540, a bottom belt drum 550, a guide block 560, and an end fixing block 570.

[0090] The base plate 110 is provided with a mounting groove, which is a through groove and is located near the cable management component;

[0091] The vertical support frame 510 is a vertically arranged rigid frame or rigid plate, and there are two of them, symmetrically arranged, both of which pass through the mounting groove and are fixed on the base plate 110.

[0092] The top belt drum 540 and the bottom belt drum 550 are both horizontally placed rigid drums, each with its two ends positioned on two vertical supports 510. They are arranged one above the other, and their axial direction is the same as that of the cable reel 320, hose reel 330, top guide roller 420, and bottom guide roller 430. The connection positions of the top belt drum 540 and the bottom belt drum 550 with the vertical supports 510 are equipped with a ratchet self-locking automatic winding mechanism or a clutch self-locking retraction mechanism.

[0093] The top belt drum 540 and the bottom belt drum 550 are used to wind up and release the top combined belt 520 and the bottom combined belt 530, respectively; one end of the top combined belt 520 is fixed and wound on the top belt drum 540; one end of the bottom combined belt 530 is fixed and wound on the bottom belt drum 550.

[0094] The guide block 560 is a horizontally placed rectangular rigid block, fixed on the top surface of the base plate 110 near the end of the base plate 110, with its length direction being the same as the axial direction of the top belt drum 540; the guide block 560 is provided with a guide groove 561; the guide groove 561 is a through groove, and the shape of the guide groove 561 matches the cross-sectional shape of the combination of the top combined belt 520 and the bottom combined belt 530, with a longitudinal section approximately a B-shaped protrusion facing upward, used to allow the top combined belt 520 and the bottom combined belt 530 to pass through simultaneously and bind the two together so that they are bonded together;

[0095] The end fixing block 570 is fixed to the top edge of the bottom plate 210 near its own end. It is a horizontal rigid block with through holes for the power transmission cable 321 and the connecting hose 331 to pass through. The other ends of the top combination strap 520 and the bottom combination strap 530 are both fixed to the end fixing block 570.

[0096] The top combination belt 520 is made of plastic, preferably polypropylene, with a thickness of more than 3 mm. It is a double-arch cross-section belt with a longitudinal cross-section that is approximately "double camel hump", m-shaped or wavy.

[0097] The bottom assembly belt 530 is a plastic belt with a thickness greater than 3 mm and a straight cross-section.

[0098] Multiple strip-shaped Velcro straps are fixed to the bottom of the top assembly strap 520 and the top of the bottom assembly strap 530. When the top assembly strap 520 and the bottom assembly strap 530 pass through the guide groove 561, they are bonded together by Velcro straps under the guidance and restriction of the guide groove 561, forming two strip-shaped spaces after assembly. The two strip-shaped spaces are used to accommodate the power transmission cable 321 and the connecting hose 331, respectively. The longitudinal section of the combination of the top assembly strap 520 and the bottom assembly strap 530 is approximately a B-shaped structure with the convex (raised) facing upward. In use, the top assembly strap 520 and the bottom assembly strap 530 form a strip-shaped sheath on the pipeline that is disconnected from the cable reel 320 and the connecting hose 331 in real time.

[0099] Furthermore, a cover 120 is fixed on the base plate 110; the cover 120 is a rigid shell that covers the cable reel 320, hose reel 330, cable management assembly, top strap reel 540 and bottom strap reel 550, and separates it from the storage compartment 130.

[0100] When using the mobile welding device of this application embodiment: if it is necessary to manually enter the working environment where the base vehicle 100 cannot enter for welding operations, the base vehicle 100 is fixed (brake) and the movable vehicle 200 and its components are manually entered into the working environment. During the entry process, the power transmission cable 321, the connecting hose 331, the top combination strap 520 and the bottom combination strap 530 are pulled to maintain the connection of the electrical and air circuits between the base vehicle 100 and the movable vehicle 200; the combination of the top combination strap 520 and the bottom combination strap 530 automatically forms the power transmission cable. The sheath of 321 and connecting hose 331; the sheath not only has the functions of scratch prevention, abrasion prevention and heat insulation, but also can prevent the pipeline from being excessively bent; after the operation is completed, the operator can hold the mobile carrier 200 and wrap the sheathed pipeline around the winding bracket 221 while leaving the work area. After approaching the base carrier 100, the sheathed pipeline, which has been wound into multiple loops, is placed on the ground. Then, the pipeline is quickly stored by rotating the cable reel 320, hose reel 330, top belt drum 540 and bottom belt drum 550.

[0101] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages:

[0102] This invention solves the technical problems of existing mobile welding devices that integrate welding and fire-fighting equipment, which are limited by their structure and shape, making them difficult to use in complex work scenarios and cumbersome in the process of setting up and retrieving pipelines in complex work scenarios. It achieves the following technical effects: the mobile welding device is flexible and convenient to use, can assist operators in moving and organizing devices and materials, can assist operators in easily entering complex work scenarios to carry out welding operations, is less likely to cause pipeline entanglement during use and is easy to retrieve after pipeline deployment, can automatically protect pipelines and is less likely to bend or be damaged during use, and has high safety.

[0103] Example 2

[0104] Considering that in actual operation, the pipeline connecting the base carrier 100 and the mobile carrier 200 sometimes needs to cross the operating production line, and even need to cross high-temperature equipment (hereinafter referred to as obstacle 001 to refer to the object that needs to be crossed), even with the sleeve formed by the combination of the top combined belt 520 and the bottom combined belt 530, it is difficult to guarantee the stability and reliability of the pipeline during use. To address the above problems, this application embodiment optimizes and improves the structure of the top combined belt 520 and the bottom combined belt 530 based on the above embodiment, and adds an auxiliary frame 600. Multiple auxiliary frames 600 are used to support the sheath composed of the top combined belt 520 and the bottom combined belt 530, suspending it in the air, thereby further reducing the probability of sheath wear, scratches, melting deformation, or even being caught in the production line. Specifically:

[0105] A row of insertion positioning holes 521 is provided on the transition area (which is elongated) between the two ridges of the top assembly band 520;

[0106] like Figure 5 As shown, a row of insertion positioning holes 521 is also provided at the positions corresponding to the insertion positioning holes 521 of the bottom combination strip 530 and the top combination strip 520.

[0107] The insertion positioning hole 521 is a through hole, used for the auxiliary frame 600 to pass through;

[0108] The auxiliary frame 600 includes a bottom carrier 610, a supporting flexible rod 620, and a top assembly 630;

[0109] like Figure 7 and Figure 8 As shown, the base carrier 610 is a circular base or a manual clamp, which is placed or fixed on the obstacle 001 during use;

[0110] The supporting flexible rod 620 is a shaped flexible tube (a tube or rod with an internal metal skeleton and an external soft sleeve), which is existing technology. It can be bent and shaped at any angle as needed. One end is fixed on the bottom carrier 610, and the length is greater than 30 cm, which serves to support the top assembly 630.

[0111] The top assembly 630 is fixed to the other end of the supporting flexible rod 620 and is normally vertically arranged, including a top rod 631 and a top support plate 632; the top rod 631 is a rigid rod, one end of which is fixed to the supporting flexible rod 620, and the other end is pointed or dome-shaped, and is inserted into the positioning hole 521 when in use; the top support plate 632 is a horizontally placed rigid plate, fixed to the top rod 631, and is used to support the top assembly belt 520 and the bottom assembly belt 530;

[0112] like Figure 9 As shown, when crossing an obstacle 001 that needs to be avoided, multiple auxiliary frames 600 are first arranged on the obstacle 001. When laying pipelines, the sheath composed of the top combination belt 520 and the bottom combination belt 530 is positioned on the auxiliary frame 600 to achieve wear prevention and heat insulation, thereby ensuring the safety of the welding process.
