DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0022] Reference Figure 1-3 , please refer to Figure 1-Figure 3 ,in, Figure 1 This is a three-dimensional structural schematic diagram of a hydraulic support maintenance welding device proposed by the utility model; Figure 2 A three-dimensional structural schematic diagram of an auxiliary welding mechanism of a hydraulic support maintenance welding device proposed by the utility model; Figure 3 A schematic top view of the three-dimensional structure of an auxiliary welding mechanism of a hydraulic support repair welding device proposed by the utility model. A hydraulic support repair welding device comprises: a welding machine body 1 and an auxiliary welding mechanism 6, a heat sink 2 is arranged on the side of the welding machine body 1, a cable 4 is connected to the output power end of the welding machine body 1, a welding gun 5 is connected to the end of the cable 4, a hydraulic support 7 is sleeved on the inner side of the auxiliary welding mechanism 6, a handrail 3 is fixedly installed on the upper right of the welding machine body 1, and an auxiliary operating handle is arranged on the welding gun 5.

[0023] In this embodiment, the auxiliary welding mechanism 6 includes an upper half ring 61 and a lower half ring 62. The sides of the upper half ring 61 and the lower half ring 62 are both provided with docking mounting holes 63. Bolts 64 are screwed onto the inner side of the docking mounting holes 63. A reinforced connection system is fixedly connected between the upper half ring 61 and the lower half ring 62. The auxiliary welding mechanism 6 is composed of two symmetrical parts screwed together by bolts 64.

[0024] Through the above-mentioned arrangement, the auxiliary welding mechanism 6 is composed of two symmetrical parts screwed together by bolts 64, which is convenient for the installation and removal of the auxiliary welding mechanism 6. The two symmetrically distributed parts are screwed together by bolts 64 to form an overall structural system. When the welding work is in progress, it can provide support for the welding points, ensure that the weld is not affected by external forces during the formation process, and ensure the load-bearing strength of the weld after formation.

[0025] In this embodiment, the reinforced connection system includes an upper straight bridge 67, a middle arch bridge 68 and a lower straight bridge 69. The upper straight bridge 67, the middle arch bridge 68 and the lower straight bridge 69 are fixedly connected to each other. The upper straight bridge 67 is fixedly connected to the bottom of the upper half ring 61, and the lower straight bridge 69 is fixedly connected to the upper end of the lower half ring 62.

[0026] Through the above-mentioned arrangement, the arrangement of the reinforced connection system forms an effective fixed support between the upper half ring 61 and the lower half ring 62. When the auxiliary welding mechanism 6 is installed, the point to be welded is located between the upper half ring 61 and the lower half ring 62. The reinforced connection system in the middle realizes the force transmission between the upper and lower sides of the welding point. After the auxiliary welding mechanism 6 is firmly fixed, the reinforced connection system assumes the force transmission effect between the upper and lower sides of the welding point, so that when the welding point is welded, the weld is not subjected to the effect of extrusion, thereby ensuring the normal forming of the weld, and then the strength of the weld after the later forming is guaranteed.

[0027] In this embodiment, the upper half ring 61 and the lower half ring 62 have the same size and specifications, and gaskets 66 are provided inside the upper half ring 61 and the lower half ring 62, and washers 611 are provided inside the upper straight bridge 67 and the lower straight bridge 69, and the gaskets 66 and the washers 611 are both made of hard rubber.

[0028] Through the above-mentioned arrangement, the gasket 66 and the gasket 611 can achieve a good force transmission effect, so that the force on the hydraulic support 7 can be evenly transmitted to the upper and lower half rings and the upper and lower straight bridges. At the same time, it also makes the entire auxiliary welding mechanism 6 not easy to slide when installed on the hydraulic support 7, and the force effect is obvious.

[0029] In this embodiment, a nut 65 is provided at the end of the bolt 64, and the nut 65 is a non-slip hexagonal nut.

[0030] By configuring in the above manner, the nut 65 is configured as an anti-slip hexagonal nut to prevent the bolt 64 from sliding when being fixed, thereby improving the connection reliability of the bolt 64 .

[0031] In this embodiment, a through opening 610 is provided inside the center arch bridge 68 .

[0032] Through the arrangement in the above manner, the middle arch bridge 68 is of arch design, which has good pressure resistance and can realize the force transmission effect between the upper straight bridge 67 and the lower straight bridge 69. At the same time, the through hole 610 arranged on the inner side of the middle arch bridge 68 enables the entire auxiliary welding mechanism 6 to be installed on the outer side of the hydraulic support 7. The cross-section where the through hole 610 is opened in the middle part is still in a suspended intersection state and does not fit the outer wall of the hydraulic support 7. When the welding point is located on the end face of the through hole 610, there is no welding blind spot and welding can be performed. The arrangement of the through hole 610 here improves the practicality of the utility model.

[0033] In this embodiment, three groups of the reinforcement connection system are evenly distributed between the upper half ring 61 and the lower half ring 62 .

[0034] By the arrangement in the above manner, three groups of reinforced connection systems are evenly arranged between the upper half ring 61 and the lower half ring 62, and then there are six groups of reinforced welding systems in the entire auxiliary welding mechanism 6, which fully enhances the strength of the overall force-bearing system.

[0035] The working principle of a hydraulic support repair welding device provided by the utility model is as follows:

[0036] When in use, the device is moved to the position to be welded, and the auxiliary welding mechanism 6 is installed first. The two parts of the auxiliary welding mechanism 6 are sleeved on the outside of the hydraulic support 7, and the position of the auxiliary welding mechanism 6 on the hydraulic support 7 is adjusted so that the position to be welded is located at the through opening 610, so that the welding point is not covered by the components on the auxiliary welding mechanism 6, and it is ensured that all the positions to be welded can be welded. After the position is adjusted, the bolt 64 is installed into the docking installation hole 63, and the nut 65 is tightened at the end, so that the entire auxiliary welding mechanism 6 forms an effective support. Subsequently, the welding machine is turned on, and the welding gun 5 is used to act on the point to be welded. After welding is completed, when the weld drops to room temperature, the auxiliary welding mechanism 6 can be removed, and the entire welding work is completed.

[0037] The above is the working process and principle of the utility model. The hydraulic support repair welding device proposed by the utility model has the following beneficial effects:

[0038] By setting up the auxiliary welding mechanism 6, it is unnecessary to dismantle the hydraulic support 7 when welding and repairing it. The auxiliary welding mechanism 6 can be directly sleeved on the outside of the hydraulic support 7, and the auxiliary welding mechanism 6 can be fixed so that it can form an effective support for the welding point, thereby ensuring that the weld is not affected by external forces before cooling, thereby ensuring the effective load-bearing capacity of the welding point in the later stage, and improving practicality. In addition, the device is simple to operate and has high working efficiency, and is particularly suitable for the emergency repair work of the hydraulic support 7 in mining production.
