Description

Technical Field

[0001] This invention relates to an auxiliary device for vertical welding of diesel engine base frames, eliminating the need to carry welding equipment, and belongs to the technical field of welding equipment. The device is mounted on a welding stand and is applicable to vertical welding of various engine base frames. During use, only the welding torch needs to be mounted on the device; other equipment such as belts and wire feeders are not required, reducing the risks associated with carrying materials and climbing heights during vertical welding and ensuring personnel safety. Background Technology

[0002] Marine diesel engines are the core power components of ships, and the structural strength and welding quality of their engine base directly affect the engine's performance and reliability. During diesel engine manufacturing, the engine base typically needs to be welded vertically, especially the upper cylinder block, where the welding position is high above the ground, requiring operators to use welding scaffolds to work at height. Traditional welding methods require operators to carry welding torches, wire reels, wire feeders, belts, and other equipment to these heights, which is not only difficult to transport but also presents the following problems: Safety hazards: Carrying items up to heights can easily lead to loss of stability for people or equipment falling, causing safety accidents; Inefficient: The limited capacity of the spooled welding wire necessitates frequent replacements, affecting welding continuity; Operational inconvenience: High-altitude environments make equipment debugging and parameter adjustment difficult, affecting welding quality. While there are some welding auxiliary equipment in the existing technology, most of them are concentrated on flat or low-altitude operations, and there is a lack of special devices for high-altitude vertical welding scenarios. Summary of the Invention

[0003] The purpose of this invention is to create an auxiliary device that eliminates the need to carry items other than the welding gun when welding the machine base and frame vertically, thus preventing accidents caused by employees carrying items up heights or objects falling from heights. This invention is designed to deliver the welding wire and shielding gas to each layer of the frame through an extended method. When in use, only the welding gun needs to be carried and connected to the device on that layer.

[0004] This invention is achieved through the following technical solution:

[0005] An auxiliary device for vertical welding of a diesel engine base frame, eliminating the need for carrying welding equipment, is characterized by comprising: A wire pusher is used to push welding wire from the ground to a high position on the welding stand; Wire feeders, installed on each layer of the welding stand, are used to deliver welding wire to the welding torch; A welding wire conduit, connecting the wire pusher and the wire feeder, is used for long-distance delivery of welding wire; Gas pipelines are connected to protective gas cylinders, and valves are installed on each floor to supply protective gas in layers. The control panel, integrated into the wire feeder, is used to adjust welding parameters. This device is attached to a welding stand and delivers welding wire and shielding gas to the corresponding cylinder based on the height of the stand. Multiple barrels of welding wire can be placed next to the welding stand to replace coiled welding wire for feeding, thus solving the drawback of frequent replacements required for coiled welding wire due to its small quantity.

[0006] The wire pusher is located on the barrel of welding wire. Its function is to push the welding wire from the ground to a higher position through the welding wire pipeline. The wire drawing machine on the welding stand pulls the welding wire to that layer for use. Each barrel of welding wire is equipped with a wire drawing machine and a wire feeder. The wire feeder is located on each layer of the stand and is connected to the gas pipeline, integrating the simultaneous output of welding wire and shielding gas.

[0007] The gas pipeline is connected to the protective gas cylinder. In addition to the main valve of the gas cylinder, there is a branch valve on each layer of the support frame. When in use, the protective gas can be used on that layer by opening the branch valve. At the same time, a pressure gauge is installed at the valve port to measure the gas pressure and prevent leakage.

[0008] The control panel, located on the wire feeder, controls the power supply, current, and voltage. Welding parameters can be adjusted via the control panel during welding. The welder only needs to carry the welding torch onto the climbing frame to enter the layer to be welded, then connect it to the wire feeder to begin welding. When welding is finished, the gas valve and control panel are turned off, and the welding torch is removed, eliminating the need to transport equipment such as belts, wire spools, and wire feeders. Compared with the prior art, the beneficial effects of the present invention are as follows: In traditional methods, equipment such as welding wire spools and wire feeders are prone to falling when working at heights. This invention eliminates this risk by using fixed pipelines to deliver welding wire and shielding gas. Operators only need to carry the welding torch into the welding area, eliminating the need to move heavy equipment like the welding wire spool and wire feeder, thus completely avoiding the risk of falls due to carrying heavy objects to heights. The gas pipeline is layered with valves and pressure gauges to monitor gas pressure in real time, preventing shielding gas leaks and ensuring a safe welding environment. Each layer of the welding stand has quick-connect interfaces, allowing the welding torch to be used immediately upon insertion, saving time on equipment transport and installation, and shortening the welding preparation cycle. The control panel is integrated into the wire feeder, allowing operators to directly adjust parameters such as current and voltage without needing to carry additional adjustment equipment, simplifying the operation process.

[0010] Figure 2 This is a schematic diagram of the auxiliary device (only one layer; the other layers are the same). Detailed Implementation

[0011] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the scope of protection of the present invention. The auxiliary device of the present invention mainly consists of the following components: Wire pusher 1: Located on the ground, used to push the welding wire from the barrel of welding wire 6 to the welding wire pipeline. Wire feeder 2: Installed on each layer of the welding stand, used to pull the welding wire from the wire pipe and feed it to the welding gun. Welding wire conduit 3: Connects the wire pusher and the wire feeder, used for long-distance delivery of welding wire. Gas pipeline 4: connected to the protective gas cylinder, and equipped with a valve 7 on each floor for supplying protective gas. Control panel 5: Integrated on the wire feeder, used to adjust welding current, voltage and other parameters.

[0012] The auxiliary device described in this invention is illustrated below using the 7G80 base as an example. The specific structure is as follows: Figure 2 As shown:

[0013] The 7G80MEC10.5 base cylinder diameter is 1400mm, and the height of the third crossbeam from the ground is 3.4m. With the auxiliary device described in this invention, the operator only needs to carry the welding torch into the layer and connect the wire feeder to weld in a certain area. Using 200KG drum welding wire, the service life is longer than that of 15KG coil welding wire, and there is no need to replace it frequently.

[0014] The welding wire is pushed through the welding wire tube by the wire pusher to the second layer of the welding stand, where the wire puller pulls the welding wire to that layer for use. The wire pusher and wire feeder work together, with each spool of welding wire equipped with one wire puller and one wire feeder. The wire feeders are located on each layer of the stand and are connected to the gas pipeline, integrating the simultaneous output of welding wire and shielding gas.

[0015] The gas pipeline is connected to the protective gas cylinder. In addition to the main valve of the gas cylinder, there is a branch valve on each layer of the stand. When in use, the protective gas can be used on that layer by opening the branch valve. At the same time, a pressure gauge 8 is installed at the valve port to measure the gas pressure and prevent leakage.

[0016] The control panel, located on the wire feeder, controls the power supply, current, and voltage. Welding parameters can be adjusted via the control panel during welding. Welders only need to carry their welding torch onto the climbing frame to reach the floor to be welded, then connect it to the wire feeder to begin welding. When welding is finished, the gas valve and control panel are turned off, and the welding torch is removed. This eliminates the need to move belts, wire spools, wire feeders, and other equipment, saving manpower while ensuring safety. This embodiment employs a pipelined welding wire delivery system, eliminating the need for manual handling of welding wire equipment; a layered gas path design ensures precise supply of protective gas; an integrated control panel simplifies welding parameter adjustment; large-capacity barrel-type welding wire reduces replacement frequency; and a modular design adapts to the needs of different machine models.
