[0002] When installing fire pipes in a building, it is necessary to weld multiple fire pipes one by one into a longer pipe. However, when welding a new fire pipe to a longer fire pipe, the longer fire pipe has been installed at a designated position and cannot be moved. Some of the installed fire pipes face the wall, and the space between the fire pipe and the wall is small. Maintenance personnel cannot carry welding equipment to enter between the fire pipe and the wall to weld the joint of the fire pipe. They can only carry the welding equipment between the fire pipe and the wall with one hand to weld the fire pipe. Moreover, maintenance personnel cannot determine the welding condition of the fire pipe, which is prone to poor welding and requires multiple welding, which is more troublesome.

If there is a leak, it is necessary to drain the water in the fire-fighting pipes again, and then repair the leak by welding, which is rather troublesome. Summary of the invention

[0023] All the electrically controlled rotating rollers 4 are provided with anti-skid rubber strips, so that the device has a better fixing effect on the fire-fighting pipe and prevents slipping.

[0024] It also includes a suction pipe 101 and a connecting pipe I 102 ; the suction pipe 101 is installed on the carrying plate I 5 ; the suction pipe 101 is connected to the connecting pipe I 102 , and the suction pipe 101 covers the electric grinding wheel 11 .

[0025] The middle parts of all the electrically-controlled rotating rollers 4 are concave toward the center of the circle, so that the electrically-controlled rotating rollers 4 can better fit with the fire-fighting pipes.

[0026] The driving unit 2 is composed of a driving motor 21, a gear 22 and a gear ring 23; four through grooves are provided at the connection between the mounting frame 1 and the driving unit 2; two driving motors 21 are installed on the mounting frame 1; all the output shafts of the driving motors 21 are fixedly connected with gears 22, and all the gears 22 are located in the through grooves corresponding to the mounting frame 1; a gear ring 23 is slidably connected in the mounting frame 1, and the gear ring 23 is meshed with all the gears 22.

[0027] When installing fire pipes in a building, it is necessary to weld multiple fire pipes one by one into a longer pipe. However, when welding a new fire pipe to a longer fire pipe, the longer fire pipe has been installed at the designated position and cannot be moved. Some of the installed fire pipes face the wall, and the space between the fire pipe and the wall is small. Maintenance personnel cannot carry welding equipment to enter between the fire pipe and the wall to perform repair welding on the joint of the fire pipe, which is not conducive to the repair of the fire pipe. The welding equipment can only be sent between the fire pipe and the wall with one hand to perform the welding work of the fire pipe. Moreover, maintenance personnel cannot determine the welding condition of the fire pipe, which is prone to poor welding and requires multiple welding, which is more troublesome. When installing and welding the fire pipe, maintenance personnel The maintenance personnel buckle the present invention on the fire-fighting pipe that needs to be welded, the electrically controlled rotating roller 4 contacts the surface of the fire-fighting pipe, and controls the electrically controlled pushing frame 3 to be pushed out, so that the electrically controlled rotating roller 4 fits together with the surface of the fire-fighting pipe, so that the present invention is fixed on the fire-fighting pipe, and then the electrically controlled rotating roller 4 is started to drive the present invention to move on the fire-fighting pipe. After the present invention moves to the docking point of the fire-fighting pipe, the present invention stops moving and the welding work of the fire-fighting pipe begins. The electric push rod Ⅰ6 is pushed out, and the mounting plate 7 and the welding head 8 move to the docking point of the fire-fighting pipe. After the welding head 8 moves to the specified position, the driving unit 2 is started, and the driving motor 21 drives the gear 22 to rotate, and the gear 22 drives the gear ring 23, and the bearing plate Ⅰ5, the electric push rod Ⅰ6, the mounting plate 7 and the welding head 8 follow the movement to weld the fire-fighting pipe.

[0028] In order to better weld the fire-fighting pipe, a mounting column 9 is added to the bearing plate Ⅰ5, a mounting seat 10 is added to the mounting column 9, an electric grinding wheel 11 is installed on the mounting seat 10, an electric push rod Ⅱ12 is added to the bearing plate Ⅰ5, and a wedge block 13 is added to the electric push rod Ⅱ12. After the present invention moves to the joint of the fire-fighting pipe, the electric grinding wheel 11 is started, and the electric grinding wheel 11 starts to rotate. Before the welding head 8 welds the fire-fighting pipe, the electric push rod Ⅱ12 is first controlled to be pushed out, and the wedge block 13 pushes the mounting seat 10. The mounting seat 10 is lifted up by the wedge block 13, and the mounting seat 10 drives the electric grinding wheel 11 to slide on the mounting column 9, and the electric grinding wheel 11 approaches the fire-fighting pipe. After the dynamic grinding wheel 11 contacts the fire-fighting pipe, the electric grinding wheel 11 grinds the joint of the fire-fighting pipe, and starts to perform grinding and chamfering on the joint of the fire-fighting pipe. The drive unit 2 is started to drive the corresponding parts and the mounting column 9, the mounting seat 10, the electric grinding wheel 11, the electric push rod II 12, and the wedge block 13 to move. After the electric grinding wheel 11 completes the grinding and chamfering of the joint of the fire-fighting pipe, the drive unit 2 drives the welding head 8 to move to the chamfer of the fire-fighting pipe to perform the welding work of the fire-fighting pipe. By performing chamfering on the joint of the fire-fighting pipe, when the welding head 8 moves to the empty groove of the fire-fighting pipe, the welding material can flow better to the joint of the fire-fighting pipe, so as to better perform the welding work of the fire-fighting pipe.

[0029] By adding a suction pipe 101 on the carrier plate Ⅰ5, and adding a connecting pipe Ⅰ102 on the suction pipe 101, the suction pipe 101 covers the electric grinding wheel 11. Before welding the fire-fighting pipe, the connecting pipe Ⅰ102 is connected to the external vacuum generator through the extension pipe. When the electric grinding wheel 11 grinds and chamfers the joint of the fire-fighting pipe, the external vacuum generator is started to provide adsorption force for the suction pipe 101 and the connecting pipe Ⅰ102. The electric grinding wheel 11 grinds the fire-fighting pipe to generate debris, which is adsorbed and collected by the connecting pipe Ⅰ102, which is beneficial to the welding of the fire-fighting pipe. Example 2

[0030] On the basis of Example 1, Figure 1 and Figure 2 As shown, it also includes a bearing plate II 110, an airbag 111, a connecting tube II 112 and a connecting tube III 113; another driving unit 2 is installed on the mounting frame 1; the bearing plate II 110 is installed on the gear ring 23 of the other driving unit 2; the bearing plate II 110 is installed on the airbag 111, and the airbag 111 is a directional expansion airbag 111; the airbag 111 is connected to the connecting tube II 112 and the connecting tube III 113.

[0031] The airbag 111 is provided with a deformation part 1111, and the deformation part 1111 is made of wear-resistant material. The deformation part 1111 faces the fire-fighting pipe, so that the airbag 111 can better fit the fire-fighting pipe.

[0032] After completing the welding of the fire-fighting pipe joint, it is necessary to let water flow through the fire-fighting pipe to detect whether there is a leak in the fire-fighting pipe. If there is a leak, it is necessary to drain the water in the fire-fighting pipe again, and then repair the leak, which is rather troublesome. By adding a new drive unit 2 to the mounting frame 1, there are two drive units 2 in the present invention, one drive unit 2 is used to drive the bearing plate I5 to move, and the other drive unit 2 is used to drive the bearing plate II 110 to move. An air bag 111 is added to the bearing plate II 110, and a connecting pipe II 112 and a connecting pipe III 113 are added to the air bag 111. An extension pipe is used to connect the connecting pipe II 112 to an external vacuum generator, and an extension pipe is used to connect the connecting pipe III 113 to an external gas source. When the welding of the fire-fighting pipe joint is completed and detection is required, the control An external air source is used to transport air to the connecting pipe III 113 and the airbag 111, and the airbag 111 begins to expand. During the expansion process, the deformed part 1111 fits with the surface of the fire-fighting pipe, and a detection space is formed between the airbag 111 and the fire-fighting pipe, and the connecting pipe II 112 is connected to the detection space. After the detection space is formed between the airbag 111 and the fire-fighting pipe, the external vacuum generator is started to provide adsorption force for the connecting pipe II 112, and the air in the detection space is sucked through the connecting pipe II 112. If a vacuum can be formed in the detection space, it proves that there is no leakage in the fire-fighting pipe in the detection space, and there is no need to pass water through the fire-fighting pipe, which is convenient for determining the welding condition of the fire-fighting pipe. If a vacuum cannot be formed in the detection space, it can be determined that there is a problem with the welding at the joint of the fire-fighting pipe, and the fire-fighting pipe joint needs to be repaired by welding.

[0033] On the basis of Example 2, Figure 2 and Figure 3 As shown, it also includes a winding roller 201, a limiting pipe 202, a mounting frame 203, an electric extrusion wheel 204 and a guide frame 205; the winding roller 201 is mounted on the supporting plate Ⅰ5, and the welding material is wound on the winding roller 201; the limiting pipe 202 is fixedly connected to the supporting plate Ⅰ5; two mounting frames 203 are fixedly connected to the mounting plate 7; the electric extrusion wheel 204 is commonly installed on all the mounting frames 203; the guide frame 205 is commonly fixedly connected to all the mounting frames 203, and the guide frame 205 is in contact with the electric extrusion wheel 204.

[0034] A bell mouth 2021 is provided on the limiting pipe 202 to facilitate the entry of welding materials.

[0035] The inner wall of the limiting pipe 202 is set to be smooth, which is convenient for guiding the welding material to move in the limiting pipe 202.

[0036] By adding a winding roller 201 and a limiting pipe 202 on the carrying plate I5, the winding roller 201 has welding material wound on it, a mounting frame 203 is added on the mounting plate 7, and an electric extrusion wheel 204 is added on the mounting frame 203. The welding material wound on the winding roller 201 is first pulled out, and then the welding material passes through the bell mouth 2021 into the limiting pipe 202. The welding material passes out of the limiting pipe 202 and is pressed on the electric extrusion wheel 204 on the mounting frame 203. When welding the fire-fighting pipe, the electric extrusion wheel 204 is started to drive the welding material to move onto the fire-fighting pipe. The welding material on the electric extrusion wheel 204 contacts the guide frame 205, and the guide frame 205 guides the welding material to the chamfer of the fire-fighting pipe. As the electric extrusion wheel 204 rotates, the welding material is sent into the chamfer of the fire-fighting pipe, so that the welding material can better stay at the chamfer of the fire-fighting pipe, which is beneficial to the welding of the fire-fighting pipe.
