Description

Technical Field

[0001] This utility model relates to the technical field of hydraulic support welding devices, specifically an automatic welding machine for repairing the inner and outer walls of hydraulic supports. Background Technology

[0002] The existing technology uses electroplating chromium to address the corrosion and wear resistance requirements of hydraulic prop plungers and cylinders in coal mines. However, electroplating chromium causes serious pollution and is now subject to national environmental protection restrictions. In addition, the electroplated chromium coating is thin and its corrosion resistance is not ideal. In order to extend the service life of the outer surface of the prop plungers and cylinders and reduce the production cost of enterprises, laser cladding technology is currently used to repair the outer surface of the worn prop plungers and cylinders. Although this technology can meet the repair requirements, the initial investment is large and the production and operating costs are relatively high.

[0003] Currently, existing utility models utilize high-power plasma arcs to melt alloy powders and employ plasma cladding technology to replace the highly polluting electroplating chromium process. Compared to laser cladding, this method offers advantages such as lower investment, lower operating costs, simpler operation, and a wider range of cladding materials. It has great application potential in the field of coal mining machinery remanufacturing, aiming to effectively solve the problem of repairing the outer surface of scrapped support plungers and cylinders using the most economical means.

[0004] For example, the hydraulic support roller plasma cladding machine disclosed in authorization announcement number CN210498766U is characterized by: including a plasma welding gun, a workpiece rotary table chassis, an X-axis transverse motion device, a Y-axis longitudinal motion device, a Z-axis lifting motion device, a powder feeder, an oscillator, a frame beam, a frame double column, an equipment base, a movable tailstock, a light shield, an electrical control cabinet, and a power supply cabinet; the electrical control cabinet, power supply cabinet, frame beam, frame double column, and workpiece rotary table chassis are mounted on the equipment base; the equipment base is provided with a track, and the movable tailstock is mounted on the track of the equipment base; the X-axis transverse motion device is located above the frame beam, and the Y-axis longitudinal motion device is fixedly installed on the Y-axis support plate of the X-axis transverse motion device, and the Y-axis longitudinal motion device is driven by the meshing of the gear and rack on the side of the Y-axis longitudinal column of the Z-axis lifting motion device. However, with such hydraulic support roller plasma welding machines, operators are prone to inhaling harmful fumes generated during welding of hydraulic supports, which can endanger their health. Furthermore, the intense light and sparks produced during welding of hydraulic supports can easily injure operators.

[0005] As can be seen from the solutions disclosed in the existing patent documents, operators are prone to inhaling harmful fumes generated by welding hydraulic supports, which endangers their health. Furthermore, the intense light and sparks generated by welding hydraulic supports can easily injure operators. Therefore, it is necessary to improve the existing technology. Utility Model Content

[0007] To achieve the above objectives, this utility model provides the following technical solution: an automatic welding machine for repairing the inner and outer walls of hydraulic supports, comprising a base, an electrical control cabinet fixedly mounted on the upper surface of the base, a vacuum cleaner mounted on the upper end of the electrical control cabinet, a filter box mounted on one side of the vacuum cleaner, a connecting pipe fixedly connected to the other side of the vacuum cleaner, a bolt sleeved inside the connecting pipe, a nut threaded to one end of the bolt, a sleeve sleeved inside the connecting pipe, a suction pipe fixedly welded to one end of the sleeve, a frame mounted on the upper surface of the base, a welding mechanism connected to the upper end of the frame, a fixing block tightly attached to the side of the welding mechanism, an opening inside the fixing block, a screw sleeved inside the opening, a washer sleeved outside the screw, and a protective cover fixedly connected to the lower end of the fixing block.

[0008] Preferably, one end of the connecting tube is tightly attached to the vacuum tube, and a sleeve is fitted onto the outside of the bolt. By inserting the sleeve into the inside of the connecting tube and passing the bolt through the connecting tube and the sleeve, the threaded connecting bolt of the nut is rotated to tighten it, which facilitates the fixed installation of the vacuum tube.

[0009] Preferably, one side of the connecting pipe is tightly attached to the nut, and a clamping mechanism is fixedly installed on the upper end face of the base. The clamping mechanism clamps the hydraulic support, and the electrical control cabinet clamps the hydraulic support. By starting the vacuum cleaner, the vacuum pipe can suck up the harmful fumes generated by the welding head welding the hydraulic support, preventing the operator from inhaling the fumes and harming their health.

[0010] Preferably, the lower end of the suction pipe is aligned with the welding position, and a support structure is installed on the upper surface of the base. The upper end of the support structure is closely attached to a hydraulic support column. When the vacuum cleaner sucks up harmful smoke and dust from the suction pipe, it can be filtered and discharged through the filter box, which can reduce the pollution of the environment by harmful smoke and dust.

[0011] Preferably, one end of the screw is connected to the welding mechanism via a thread, and the screw is sleeved inside the fixing block. By rotating the screw on the outside of the open ferrule screw, the washer is pressed against the welding mechanism, which facilitates the fixed installation of the protective cover.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model uses a sleeve inserted into the inside of a connecting pipe and a bolt passed through the connecting pipe and the sleeve. The threaded connecting bolt is tightened by rotating the screw nut, which facilitates the fixed installation of the suction pipe. By starting the vacuum cleaner, the suction pipe can suck up the harmful fumes generated by the welding head and the hydraulic support, preventing the operator from inhaling the fumes and harming their health. After the vacuum cleaner sucks up the harmful fumes from the suction pipe, they can be filtered and discharged through the filter box, which can reduce the pollution of the environment by harmful fumes.

[0016] 2. This utility model uses the outside of the open ferrule screw to rotate and tighten the screw, causing the washer to press the fixing block against the welding mechanism, which facilitates the installation of the protective cover. The design of the protective cover can block the strong light and sparks generated by the welding head welding the hydraulic support, thereby preventing the strong light and sparks from injuring the operator. By rotating and loosening the screw, the fixing block is unrestrained, making it easy to move the protective cover downwards for quick removal and replacement. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 The diagram shows an automatic welding machine for repairing the inner and outer walls of hydraulic supports. It includes a base 1, with an electrical control cabinet 11 fixedly mounted on the upper surface of the base 1. The electrical control cabinet 11 is existing technology. A vacuum cleaner 12 (model HF100, also existing technology) is mounted on the upper part of the electrical control cabinet 11. The vacuum cleaner 12 is connected to a control switch, which in turn connects to the power supply. A filter box 13 is mounted on one side of the vacuum cleaner 12, and a connecting pipe 14 is fixedly connected to the other side of the vacuum cleaner 12. Bolts 15 are fitted inside the connecting pipe 14. One end of the bolt 15 is connected to a nut 16 by a thread. A sleeve 17 is fitted inside the connecting pipe 14. A suction pipe 18 is fixedly welded to one end of the sleeve 17. A frame 2 is installed on the upper surface of the base 1. A welding mechanism 21 is connected to the upper end of the frame 2. The welding mechanism 21 is existing technology. A fixing block 22 is attached to the side of the welding mechanism 21. An opening 23 is provided inside the fixing block 22. A screw 24 is fitted inside the opening 23. A washer 25 is fitted outside the screw 24. A protective cover 26 is fixedly connected to the lower end of the fixing block 22.

[0025] To prevent operators from inhaling fumes and harming their health, one end of the connecting pipe 14 is tightly fitted with the suction pipe 18. A sleeve 17 is fitted onto the outside of the bolt 15. By inserting the sleeve 17 into the connecting pipe 14 and passing the bolt 15 through the connecting pipe 14 and the sleeve 17, the threaded connecting bolt 15 is tightened by rotating the threaded nut 16, which facilitates the fixed installation of the suction pipe 18. One side of the connecting pipe 14 is tightly fitted with the nut 16. A clamping mechanism 19 is fixedly installed on the upper end face of the base 1. The clamping mechanism 19 is prior art and clamps the hydraulic support 1. 10. The electrical control cabinet 11 clamps the hydraulic support 110. By starting the vacuum cleaner 12, the vacuum pipe 18 can suck up the harmful fumes generated by the welding head 27 welding hydraulic support 110, preventing the operator from inhaling the fumes and harming their health. The lower end of the vacuum pipe 18 is aligned with the welding position. The upper end of the base 1 is equipped with a support structure 111. The upper end of the support structure 111 is in close contact with the hydraulic support 110. When the vacuum cleaner 12 sucks up the harmful fumes from the vacuum pipe 18, they can be filtered and discharged through the filter box 13, which can reduce the pollution of the environment by harmful fumes.

[0026] To prevent strong light and sparks from injuring the operator, one end of screw 24 is threadedly connected to welding mechanism 21. Screw 24 is fitted inside fixing block 22. By rotating and tightening screw 24 through opening 23 to clamp the outside of screw 24, the washer 25 is pressed against fixing block 22 to welding mechanism 21, facilitating the installation of protective cover 26. The lower end of protective cover 26 covers the welding position. Welding mechanism 21 is equipped with welding head 27. The design of protective cover 26 can block the strong light and sparks generated by welding head 27 to welding hydraulic support 110, thereby preventing strong light and sparks from injuring the operator. The lower end of welding mechanism 21 is in close contact with protective cover 26, and the surface of fixing block 22 is in close contact with washer 25. By rotating and loosening screw 24, fixing block 22 is released, making it easy to move downwards and quickly remove and replace protective cover 26.

[0027] This automated welding machine for repairing the inner and outer walls of hydraulic supports uses a special mechanism. A sleeve 17 is inserted into a connecting pipe 14, and a bolt 15 is passed through both the connecting pipe 14 and the sleeve 17. Tightening the threaded connection bolt 15 by rotating the tightening nut 16 facilitates the installation of a suction pipe 18. Starting the vacuum cleaner 12 allows the suction pipe 18 to extract harmful fumes generated by the welding head 27 while welding the hydraulic support 110, preventing operators from inhaling harmful fumes. After the vacuum cleaner 12 extracts harmful fumes from the suction pipe 18, they are filtered and discharged through a filter box 13, reducing environmental pollution. By using the opening 23 to clamp the screw 24 on the outside, rotating the tightening screw 24 causes the washer 25 to press the fixing block 22 against the welding mechanism 21, facilitating the installation of a protective cover 26. The protective cover 26 is designed to shield the operator from the intense light and sparks generated by the welding head 27 while welding the hydraulic support 110. By rotating the loosening screw 24, the fixing block 22 is released, allowing the protective cover 26 to be moved downwards for quick removal and replacement.
