Description

Technical Field

[0001] The invention relates to the technical field of pipeline installation, and in particular to a building electrical pipeline installation device and an installation method thereof. Background Art

[0002] All installed power facilities need to transmit electrical energy through electrical wires. Generally, an insulating sleeve is put on the outside of the electrical wires to prevent leakage between the electrical wires. The insulating sleeve is then installed in the concrete through an embedded fixture. However, most of the wire pipes used in electrical engineering construction on the market are installed and fixed manually. When the pipes need to be connected, disassembly and assembly are very difficult, and uneven gluing causes the pipelines to be non-waterproof and skewed, affecting the construction quality. For example, the Chinese utility model patent with announcement number CN212676841U relates to the field of wire pipe installation technology, specifically a wire pipe installation and fixing device for electrical engineering construction, including a base, the base is provided with two, the surface of the base is provided with a fixing plate, the surface of the fixing plate is provided with a fixing screw, the surface of the base is provided with a flexible pad, and the base A protective plate is arranged on the surface, a splicing groove is opened on the surface of the protective plate, a through hole is opened on the surface of the splicing groove, and a pin is inserted inside the through hole; the wire pipe installation and fixing device for electrical engineering construction proposed in the prior art assembles two bases with the plug-in groove and the plug-in plate, and then fixes the fixing plate together with the base to the wall by a fixing screw, and after the pipe body is pressed against the flexible pad on the surface of the base, the finger pull ring drives the pin to stretch the tension spring outward, and then the two protective plates are assembled and the pull ring is released, and the pin is inserted into the through hole to prevent the two protective plates from separating, so as to facilitate the loading and unloading of the pipe body.

[0003] However, most of the facilities in the prior art are large in size, making it difficult to quickly install and portablely disassemble the pipelines. Inaccurate positioning during pipe sealing leads to glue leakage and air leakage, resulting in construction acceptance failure. Therefore, there is an urgent need for such a building electrical pipeline installation device and installation method Summary of the invention

The glue cylinder is slidably installed with the glue cylinder rack. An air push base is fixedly installed on the glue cylinder. A glue pressing piston is slidably installed in the glue cylinder.

[0011] The rotation of the active motor drives the rotation of the small gear. Due to the meshing of the small gear and the upper gear rack, it drives the glue application rack to slide on the upper gear rack and the lower gear rack, thereby driving the rotation of the glue cylinder. By filling gas into the air push base, the glue pressing piston descends, extruding the glue in the glue cylinder, realizing a circle of gluing on the pipeline. Under the action of the glue spring and the lower spring, the glue cylinder always keeps in contact with the outer wall of the pipeline.

A clamping device is arranged on the pressing device. The clamping device includes a sliding block 201, an upper wheel 207 and a side wheel 211. The sliding block 201 is slidably installed with the sliding column 118. A pipeline 4 is arranged between the side wheel 211 and the upper wheel 207. The clamping device is used to clamp the pipeline 4. The pressing device is used to assist in clamping the pipeline 4 and moving the pipeline 4. A gluing device is fixedly installed on the pressing device. The gluing device includes a connecting frame 303. The connecting frame 303 is fixedly installed with the main frame 110. The gluing device is used to glue and connect the pipeline 4.

[0031] During use, the pipeline 4 to be installed is placed in the middle of the clamping device. The installer holds the pressing device. The pressing device acts to make the clamping device clamp the pipeline 4. At the same time, the relative position of the pipeline 4 and the gluing device is adjusted through the pressing device. The pipeline 4 is sleeved on the pipeline in the bridge that has been installed. Subsequently, the gluing device connects the pipeline 4 with the installed pipeline. The pipeline is made of PVC material. During the preliminary preparation, the inner and outer diameters at the interface can ensure fitting.

[0032] As Figure 2 、 Figure 3 、 Figure 4As shown in the figure, the pressing device includes a guide post 107 slidably mounted on the main frame 110. A lower pressing plate 102 is fixedly mounted on the guide post 107. A rotating rod 101 is rotatably mounted on the lower pressing plate 102. The rotating rod 101 has an external thread, and the hole in the lower pressing plate 102 has an internal thread. The rotating rod 101 and the lower pressing plate 102 form a threaded fit. The rotating rod 101 is rotatably mounted with the main frame 110. A lower frame 111 is slidably mounted below the main frame 110. A lower pressing rod 103 is fixedly mounted on the lower frame 111. A return spring 104 is provided between the lower pressing rod 103 and the main frame 110. A lower pressing tube 106 is slidably mounted on the main frame 110. An extrusion spring 105 is provided between the lower pressing tube 106 and the lower pressing plate 102. A motor frame 116 is fixedly mounted on the lower frame 111.

The lower pressing tube 106 is slidably mounted with a sliding column 118. An inner spring 117 is provided between the lower pressing tube 106 and the sliding column 118.

[0033] By twisting the rotating rod 101, the lower pressing plate 102 descends, the guide post 107 slides in the main frame 110, and the extrusion spring 105 is compressed. First, it drives the lower pressing tube 106 to descend, drives the sliding block 201 to descend, thereby driving the clamping device to clamp the pipeline 4. At the same time, the descent of the lower pressing plate 102 drives the lower pressing rod 103 to descend, thereby driving the lower frame 111 to descend, so that the sliding wheel 113 contacts the pipeline 4. When it is necessary to adjust the relative position between the pipeline 4 and the pressing device, the sliding motor 115 rotates to drive the sliding wheel 113 to rotate through the upper gear 114 and the lower gear 112, so as to drive the pipeline 4 to perform axial movement.

[0034] As shown in Figure 5 , Figure 6 , Figure 7 the figure, the clamping device includes a connecting rod 202 rotatably mounted on the sliding block 201. A moving arc rod 204 is rotatably mounted on the connecting rod 202. An arc-shaped frame 203 is slidably mounted on the moving arc rod 204. A positioning pin 205 is fixedly mounted on the arc-shaped frame 203. The positioning pin 205 is slidably mounted with the moving arc rod 204. A wheel frame 206 is fixedly mounted on the arc-shaped frame 203. An upper wheel 207 is rotatably mounted on the wheel frame 206. The wheel frame 206 is fixedly mounted with a notch plate 109.

A wheel spring 209 is provided between the side wheel frame 210 and the moving arc rod 204. A side wheel 211 is rotatably mounted on the side wheel frame 210.

[0035] The downward movement of the pressing tube 106 drives the sliding block 201 to slide downward along the sliding column 118. The sliding block 201 drives the connecting rod 202 to rotate, and the connecting rod 202 drives the moving arc rod 204 to slide in the arc-shaped frame 203, thereby driving the side wheel frame 210 to rise. The side wheel frame 210 drives the side wheels 211 to rise, and the pipeline 4 placed between the two side wheels 211 and the upper wheel 207 is clamped by the upper wheel 207 and the two side wheels 211.

[0036] As Figure 8 , Figure 9 , Figure 10 shown, the gluing device includes an upper gear rack 301 fixedly installed on the connecting frame 303. A lower gear rack 302 is fixedly installed below the upper gear rack 301. A glue application rack 306 is slidably installed on the upper gear rack 301 and the lower gear rack 302. An activity motor 304 is fixedly installed on the glue application rack 306. A small gear 305 is fixedly installed on the output shaft of the activity motor 304. The small gear 305 meshes with the upper gear rack 301 and the lower gear rack 302. An upper column 307 is fixedly installed on the glue application rack 306. A glue cylinder rack 309 is slidably installed on the upper column 307. A glue spring 308 is arranged between the glue cylinder rack 309 and the glue application rack 306. A lower column 311 is fixedly installed on the glue application rack 306. A cylinder base 315 is slidably installed on the lower column 311. A lower spring 312 is arranged between the cylinder base 315 and the lower column 311. A glue cylinder 310 is placed on the cylinder base 315. The glue cylinder 310 is slidably installed with the glue cylinder rack 309. An air push base 314 is fixedly installed on the glue cylinder 310. A glue pressing piston 313 is slidably installed in the glue cylinder 310.

[0037] The rotation of the activity motor 304 drives the small gear 305 to rotate. Due to the meshing of the small gear 305 and the upper gear rack 301, it drives the glue application rack 306 to slide on the upper gear rack 301 and the lower gear rack 302, thereby driving the glue cylinder 310 to rotate. By filling gas into the air push base 314, the glue pressing piston 313 is lowered, and the glue in the glue cylinder 310 is extruded to achieve gluing in a circle on the pipeline 4. Under the action of the glue spring 308 and the lower spring 312, the glue cylinder 310 is always kept in contact with the outer wall of the pipeline 4.

[0038] When the glue cylinder 310 needs to be replaced, manually raise the glue cylinder rack 309, and then pull out the glue cylinder 310 from the cylinder base 315 and take out the glue cylinder 310 for replacement.

[0039] As Figure 5 , Figure 7 shown, a long arc-shaped groove is provided on the moving arc rod 204, and the diameter of the positioning pin 205 is the same as the groove width of the moving arc rod 204.

[0040] As Figure 5 , Figure 6 , Figure 7As shown, there are two symmetric clamping devices arranged below the pressing device, and two symmetric side wheels 211 are arranged on each clamping device.

[0041] As Figure 5 , Figure 6 shown, the central points of the upper wheel 207 and the side wheels 211 are located in the same plane, and the diameter of the side wheels 211 is larger than the diameter of the upper wheel 207.

[0042] A method for installing building electrical pipelines includes the following steps: Step 1, place the pipeline 4 between the upper wheel 207 and the two side wheels 211; Step 2, twist the rotating rod 101 so that the upper wheel 207 and the side wheels 211 clamp the pipeline 4, and the sliding wheel 113 contacts the pipeline 4; Step 3, rotate the sliding motor 115 to drive the sliding wheel 113 to rotate, so that the end of the pipeline 4 reaches below the rubber cylinder 310; Step 4, put the pipeline 4 into the already installed pipeline; Step 5, inject gas into the air-pushing base 314, and at the same time rotate the movable motor 304 to drive the rubber cylinder 310 to rotate, so that the rubber cylinder 310 adhesively fixes a circle of the pipeline 4, connecting the pipeline 4 with the already installed pipeline; Step 6, move the device out of the pipeline 4.

[0043] Working principle: When in use, place the pipeline 4 to be installed in the middle of the clamping device. The installer holds the pressing device and turns the rotating rod 101, causing the lower pressing plate 102 to descend. The guiding column 107 slides in the main frame 110, and the compression spring 105 is compressed. First, it drives the lower pressing pipe 106 to descend. The descent of the lower pressing pipe 106 drives the sliding block 201 to slide downward along the sliding column 118. The sliding block 201 drives the connecting rod 202 to rotate, and the connecting rod 202 drives the moving arc rod 204 to slide in the arc-shaped frame 203, thereby driving the side wheel frame 210 to rise. The side wheel frame 210 drives the side wheels 211 to rise, and the pipeline 4 placed between the two side wheels 211 and the upper wheel 207 is clamped by the upper wheel 207 and the two side wheels 211. At the same time, the descent of the lower pressing plate 102 drives the lower pressing rod 103 to descend, thereby driving the lower frame 111 to descend, making the sliding wheel 113 contact the pipeline 4. When it is necessary to adjust the relative position of the pipeline 4 and the pressing device, the sliding motor 115 rotates and drives the sliding wheel 113 to rotate through the upper gear 114 and the lower gear 112, driving the pipeline 4 to move axially, so that the pipeline 4 to be connected is docked and inserted into the pre-fixed pipeline on the bridge. The pipeline is made of PVC material. During the preliminary preparation, the inner and outer diameters at the interface can ensure insertion. Subsequently, the movable motor 304 rotates to drive the small gear 305 to rotate. Due to the meshing of the small gear 305 and the upper gear frame 301, it drives the caulking frame 306 to slide on the upper gear frame 301 and the lower gear frame 302, thereby driving the glue barrel 310 to rotate. By filling gas into the air-pushing base 314, the pressure glue piston 313 descends, extruding the glue in the glue barrel 310 to achieve caulking in a circle on the pipeline 4. Under the action of the glue spring 308 and the lower spring 312, the glue barrel 310 always keeps in contact with the outer wall of the pipeline 4. When it is necessary to replace the glue barrel 310, manually lift the glue barrel frame 309, and then pull out the glue barrel 310 from the barrel seat 315 and take out the glue barrel 310 for replacement.
