Description

Technical Field

[0001] This utility model relates to the field of pipeline construction, and in particular to a clamping device for building water supply pipeline construction. Background Technology

[0002] To ensure the water demand in residential buildings, a large number of water supply pipes need to be laid inside the buildings. These water supply pipes are mostly laid on the side walls or ceilings to avoid ground construction. However, when installing these suspended pipes, workers often need to lift them up near the installation location. The current construction method is quite troublesome, time-consuming and labor-intensive, which is not conducive to the accurate installation of pipes, slows down the construction efficiency, and increases the labor intensity of workers.

[0003] For example, patent document CN219427514U discloses a clamping device for building water supply pipeline construction, including a base plate, a slide rail on the upper part of the base plate, sliders slidably mounted on the left and right sides of the slide rail, and a clamping assembly on each slider. The clamping assembly includes a lower clamping plate mounted on the upper part of the slider. The lower clamping plate is T-shaped, with a V-groove on its vertical part. Guide posts are mounted on the front and rear sides of the horizontal part of the lower clamping plate, and a horizontal plate is mounted on the upper part of the guide posts. A screw is threaded onto the axis of the horizontal plate, passing through the horizontal plate, and an upper clamping plate adapted to the lower clamping plate is mounted at the bottom of the screw. This utility model can clamp and fix the two sections of water pipe to be joined using the clamping assembly, facilitating the hot-melt work of the hot-melt machine. It eliminates the need for manual handling of the water pipes during hot-melt welding, thus avoiding burns from the hot-melt machine's melting head or the softened water pipes, making operation safer and more convenient.

[0004] The aforementioned device uses a clamping mechanism to position the pipe at the installation location and avoids potential burns during the hot-melt process. However, it lacks lifting and tilting functions and cannot be adapted to existing water supply pipe construction methods in residential buildings. Utility Model Content

[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] like Figures 1-8As shown, a clamping device for building water supply pipeline construction includes a mobile trolley, which includes a trolley support 101. Several casters 102 are mounted on the bottom of the trolley support 101. A scissor lift 108 is mounted on the trolley support 101. A lifting drive assembly for driving the scissor lift 108 is provided on the trolley support 101. A tilting mechanism is provided on the top of the scissor lift 108. The tilting mechanism includes a lifting platform 201 hinged to the top of the scissor lift 108. Two symmetrically arranged sliding baffles 202 are welded to the lifting platform 201. A tilting bracket 203 is slidably connected within the sliding baffles 202. A clamping platform 204 is rotatably connected to one end of the tilting bracket 203. A pushing slider 206 is slidably connected within the tilting bracket 203. A tilting connecting rod 205 is rotatably connected to the top of the pushing slider 206. The tilting connecting rod 205 is rotatably connected to the clamping platform 204. A lifting mechanism for... The rotating drive assembly that drives the rotating bracket 203 and pushes the slider 206 to move has two clamping mechanisms symmetrically arranged at both ends of the clamping platform 204. To meet the actual needs of water supply pipeline construction in residential buildings, that is, to lift the water supply pipeline to the ceiling or place it vertically in front of the wall, the pipeline construction clamping device has lifting and rotating functions. The process of using this device is as follows: the worker places the pipeline in the clamping mechanism, and then the lifting drive assembly drives the scissor lift 108 to move. The scissor lift 108 drives the lifting platform 201 to a position near the ceiling. When placing the vertical pipeline, the rotating drive assembly drives the rotating bracket 203 to move. The rotating bracket 203 drives the clamping platform 204 to move, and then drives the push slider 206 to move. The push slider 206 pushes the rotating connecting rod 205 to move. The rotating connecting rod 205 drives the clamping platform 204 to rotate, and the clamping platform 204 drives the pipeline to rotate.

[0030] The lifting drive assembly includes a lifting motor 103 fixedly connected to the rear side of the trolley bracket 101. A lifting screw 105 is rotatably connected to the trolley bracket 101. A movable push plate 106 is threadedly connected to the lifting screw 105. The movable push plate 106 is slidably connected to the trolley bracket 101. The top of the movable push plate 106 is rotatably connected to one end of the bottom of the scissor lift 108. The other end of the bottom of the scissor lift 108 is rotatably connected to the trolley bracket 101. The lifting motor 103 drives the lifting screw 105 to rotate. The lifting screw 105 drives the movable push plate 106 to move through the threaded connection. The movable push plate 106 pushes the scissor lift 108 to move. In this way, the scissor lift 108 opens and can push the lifting platform 201 to rise.

[0031] The tilting drive assembly includes a tilting motor 210 fixedly connected to the bottom of the lifting platform 201. A tilting screw 209 is rotatably connected to the bottom of the lifting platform 201. The output end of the tilting motor 210 is fixedly connected to the tilting screw 209. The tilting screw 209 is threadedly connected to the push slider 206. A slide rod 207 is fixedly connected to the tilting bracket 203. The slide rod 207 passes through the push slider 206. A return spring 208 is fixedly connected between the push slider 206 and the front end of the tilting bracket 203. The return spring 208 is sleeved on the slide rod 207. Two symmetrically arranged protrusions are provided on the outer side of the tilting bracket 203. The protrusions can interact with the sliding baffle 202. The rotating bracket 203 has two symmetrically arranged protrusions on its outer side, which can contact the sliding baffle 202. The rotating motor 210 drives the rotating screw 209 to rotate. The rotating screw 209 drives the slider 206 to move through a threaded connection. The slider 206 pushes the rotating bracket 203 to move through the return spring 208. After the protrusions on the side of the rotating bracket 203 contact the sliding baffle 202, the rotating bracket 203 is limited by the sliding baffle 202 and cannot continue to move. Then the slider 206 continues to move, and the slider 206 pushes the rotating connecting rod 205 to move. The rotating connecting rod 205 pushes the clamping platform 204 to rotate.

[0032] The clamping mechanism includes a clamping bracket 301 bolted to the clamping platform 204. Two symmetrically arranged clamping blocks 302 are slidably connected to the clamping bracket 301. A clamping spring 305 is fixedly connected between the clamping blocks 302 and the clamping bracket 301. A tensioning link 304 is hinged to the bottom of the clamping blocks 302. A T-block 303 is slidably connected to the bottom of the clamping bracket 301. The T-block 303 is hinged to the two tensioning links 304. A clamping groove is provided on the side of the clamping block 302, and the upper end of the clamping groove is arc-shaped. The operator places the pipe between two clamping blocks 302. The clamping blocks 302 clamp the pipe under the action of the clamping spring 305. In addition, electric telescopic cylinders (not shown in the figure) can be set on both sides of the clamping blocks 302. The electric telescopic cylinders are used to push the two clamping blocks 302 closer together to clamp the pipe. This is existing technology and will not be described in detail here. After the pipe is fixed on the ceiling or wall, the device moves in the opposite direction. Due to the arc action of the clamping spring 305 and the upper end of the clamping block 302, the pipe can be directly released from the clamping of the clamping block 302.

[0033] A push handle 104 is fixedly connected to the rear side of the trolley bracket 101. Two symmetrically arranged unlocking protrusions 107 are fixedly connected to the front and rear of the top of the trolley bracket 101. The upper end of the unlocking protrusions 107 can contact the bottom of the T-shaped block 303. After the clamping platform 204 returns to the horizontal position, the scissor lift 108 drives the lifting platform 201 to descend. After descending to a certain position, the bottom of the T-shaped block 303 contacts the unlocking protrusions 107. The T-shaped block 303 is stationary, but the clamping platform 204 continues to descend. Thus, relative movement occurs between the T-shaped block 303 and the clamping bracket 301. The tensioning linkage 304 drives the clamping block 302 to open. In this way, the operator clamping mechanism opens automatically, which facilitates the quick clamping of pipes.

[0034] Working Principle: To meet the actual needs of water supply pipeline construction in residential buildings, which requires lifting the water supply pipeline to the ceiling or placing it vertically against the wall, the pipeline construction clamping device has both lifting and tilting functions. The device is used as follows: the worker places the pipeline between two clamping blocks 302. The clamping blocks 302 clamp the pipeline under the action of the clamping spring 305. Then, the lifting motor 103 drives the lifting screw 105 to rotate. The lifting screw 105 drives the moving push plate 106 to move through a threaded connection. The moving push plate 106 pushes the scissor lift 108 to move, thus opening the scissor lift 108 and driving the lifting platform 201 to a position near the ceiling. When placing the vertical pipeline, the tilting motor 210 drives the tilting screw 209 to rotate. The tilting screw 209 drives the sliding block 206 to move through a threaded connection. The sliding block 206 is pushed by the return spring 208. The flip bracket 203 moves, and after the protrusion on the side of the flip bracket 203 contacts the sliding baffle 202, the flip bracket 203 is limited by the sliding baffle 202 and cannot move further. Then, the slider 206 is pushed to continue moving, and the slider 206 pushes the flipping linkage 205 to move. The flipping linkage 205 pushes the clamping platform 204 to flip, so that the pipeline can be positioned in the predetermined installation position, improving the pipeline construction efficiency and reducing the labor intensity of the workers. After the clamping platform 204 returns to the horizontal, the scissor lift 108 drives the lifting platform 201 to descend. After descending to a certain position, the bottom of the T-block 303 contacts the unlocking protrusion 107. The T-block 303 is stationary, but the clamping platform 204 continues to descend. Thus, relative movement occurs between the T-block 303 and the clamping bracket 301. The tensioning linkage 304 drives the clamping block 302 to open. In this way, the worker clamping mechanism is automatically opened, which facilitates the quick clamping of the pipeline.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
