Description

Technical Field

[0001] The utility model belongs to the field of installation of water supply and drainage pipes, and particularly relates to a positioning device for installing water supply and drainage pipes. Background Technique

[0002] Water supply and drainage refer to water supply and water discharge. In a water supply and drainage system, the materials of water supply and drainage pipes include metal and plastic. Generally, metal pipes are connected by welding and flanges, and plastic water supply and drainage pipes are generally connected by hot melting and gluing.

[0003] When connecting plastic water supply and drainage pipes, generally, the two pipes are connected by hot melting through a joint. When connecting one end, the inside of the joint and the outside of the connecting pipe are heated and melted respectively, and then the pipe is inserted into the marked depth very quickly while keeping the horizontal direction without rotation, forming a uniform flange body with the joint; when connecting the other end, the same steps are adopted to heat the inside of the joint and the outside of the other connecting pipe, and then the pipe is inserted into the joint horizontally without rotation. When connecting the other end, it is equivalent to directly connecting two pipes. In actual operation, the connected pipes are very long and heavy. If manually connected directly, it is extremely easy to have a connection deviation, and it is impossible to accurately insert the other pipe into the joint, and the hot-melt end is easily damaged; at worst, the appearance is damaged, and at best, the connection is not sealed, resulting in subsequent leakage. Summary of the Invention

[0004] The purpose of the utility model is to provide a fixing device for water supply and drainage pipe construction, which has a simple structure and is convenient to operate, and can quickly and accurately complete the hot melting connection of water supply and drainage pipes.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A positioning device for installing water supply and drainage pipes, comprising a fixing part and a guiding part. The fixing part includes a first support frame and a fixer; the first support frame includes a first support plate and a first mounting frame. The first mounting frame is detachably connected to the upper part of the first support plate, and the top extends horizontally to form a first horizontal extension part; the upper part of the fixer is arc-shaped, and both ends extend vertically downward to form a first vertical extension part, and the arc is semi-circular, and its inner diameter is adapted to the outer diameter of the fixed pipe. The extension length of the first vertical extension part is equal to the radius of the semi-circle. The fixer is fixed to the lower part of the first horizontal extension part of the first mounting frame; the guiding part includes a second support frame and a guide.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following further describes the present utility model in detail with reference to the drawings.

[0021] See Figures 1 - 4As shown in the figure, a positioning device for the installation of water supply and drainage pipes includes a fixing part and a guiding part. The fixing part includes a first support frame 1 and a fixator 2. The first support frame 1 includes a first support plate 11 and a first mounting frame 12. The first mounting frame 12 is detachably connected to the upper part of the first support plate 11, and its top horizontally extends to form a first horizontal extension part 13. The upper part of the fixator 2 is arc-shaped, and both ends vertically extend downward to form first vertical extension parts (not marked in the figure). The arc is semi-circular, and its inner diameter is adapted to the outer diameter of the pipe to be fixed, so that the pipe can just pass through the inside of the fixator 2 and generate a fastening effect. The extension length of the first vertical extension part is equal to the radius of the semi-circle, so that the upper part and both sides of the pipe can be completely wrapped by the fixator 2. When the fixator 2 is lifted upward, the pipe can completely come out of the fixator, which is convenient for disassembling and installing the pipe. And when the bottom of the fixator 2 contacts the first support plate 11, the bottom of the pipe contacts the first support plate 11, giving a supporting force to the first support plate 11, so that the pipe is fixed in all directions of up, down, left and right in the fixator 2. The fixator 2 is fixed to the lower part of the first horizontal extension part 13 of the first mounting frame 12. The guiding part includes a second support frame 3 and a guide 4. The second support frame 3 has the same structure as the first support frame 1, including a second support plate 31 and a second mounting frame 32. The top of the first mounting frame 12 horizontally extends to form a second horizontal extension part. The guide 4 has the same structure as the fixator 2, including an upper arc-shaped structure and a lower second vertical extension part (not marked in the figure). The pipe is fixed in all directions of up, down, left and right in the guide 4 and can move back and forth under the action of an external force. During manufacturing, the inner wall of the guide 4 is smoother than the inner wall of the fixator 2, which is convenient for pushing the pipe forward. A first connecting rod 5 is arranged between the fixing part and the guiding part. One end of the first connecting rod 5 is connected to the fixator 2, and the other end is connected to the guide 4. The connecting line of the centers of the arcs of the upper parts of the guide 4 and the fixator 2 is parallel to the connecting rod. In this way, the central axes of the pipes in the guide 4 and the fixator 2 are always on the same straight line, making the pipe connection fast and accurate.

[0022] Since the connector is short and light in weight, it can be directly connected by the naked eye during installation, and the probability of deviation is small. This device is mostly used for pipes laid horizontally on the ground and underground. When in use, the end that is first connected to the connector is installed on the fixing part as the fixed pipe, then the connecting pipe is installed on the guiding part, and then the connectors on the fixed pipe and the connecting pipe are melted by heat, and then an external force is used to push the connecting pipe close to the connector until the connecting pipe extends into the connector to the established length. After waiting for the pipe connection to cool slightly, the fixing device is removed. First, the bolts fixing the first mounting bracket 12 and the second mounting bracket 32 are unscrewed, and then the first mounting bracket 12 and the second mounting bracket 32 are lifted upward. Since the fixing part is installed on the first horizontal extension of the first mounting bracket 12 and the guiding part is installed on the second horizontal extension of the second mounting bracket 32, the fixing part and the guiding part are also lifted. At this time, only the first support plate 11 and the second support plate 31 need to be pulled out to complete the disassembly. The disassembly is simple and fast. When connecting continuously, after placing each component in the corresponding position, the first mounting bracket 12 is fixed to the first mounting plate, and the second mounting bracket 32 is fixed to the second mounting plate to complete the fixation.

[0023] The fixing part adopts the structure of an arc plus a first vertical extension plate, which can prevent the pipe from swinging left and right, increase the stability of the pipe, and at the same time, it is convenient to disassemble the fixing device after the pipe connection is completed. As long as the first mounting bracket 12 is removed, the fixator 2 can be removed from the pipe. The first connecting rod 5 is parallel to the line connecting the centers of the arcs of the fixing part and the guiding part, so that the central axes of the pipes passing through the guiding part and the fixing part coincide, so that the two pipes to be connected will not deviate during connection. Among them, the pipe in the fixing part is fixed by the fixing part and will not shake up, down, left or right. The pipe in the guiding part approaches the pipe in the fixing part under the action of an external force, and the connecting pipe is accurately connected to the fixing part through the guiding of the guiding part, improving the connection accuracy and connection efficiency.

[0024] As Figure 1 shown, a second connecting rod 6 is further provided between the fixing part and the guiding part. One end of the second connecting rod 6 is connected to the first support plate 11 on the fixing part, and the other end is connected to the second support plate 31 of the guide 4. This makes the relative position of the fixing part and the guiding part more stable, and the central axes of the pipes in the guide 4 and the fixator 2 are always on the same straight line.

[0025] Both the first connecting rod 5 and the second connecting rod 6 between the fixing part and the guiding part are connected by bolts. The disassembly and installation are simpler, which is convenient for storage and transportation.

[0026] As Figure 1 and Figure 3As shown, the fixture 2 on the fixing part is connected to the first mounting bracket 12 by bolts, which makes the disassembly of the fixture 2 and the guide 4 convenient, and the guide 4 and the fixture 2 can be replaced according to the size of the connecting pipe to adapt to pipes of different sizes, making it flexible and convenient to use. Moreover, a first positioning pin 14 is provided on the fixture 2, and corresponding jacks are provided on the first mounting bracket 12. The installation of the guide 4 on the guiding part is the same as that of the fixture 2 on the fixing part, and a second positioning pin 34 is provided, and corresponding jacks are provided on the second mounting bracket 32. This prevents the positions of the fixture 2 and the guide 4 from shifting, increasing the accuracy of the device.

[0027] As Figure 2 shown, a first roller 41 that can rotate around the central axis is provided inside the guide 4. The rolling direction of the first roller 41 rotates along the length direction of the drainage pipe passing through the guide 4, and the first roller 41 is flush with the inner surface of the guide 4. This helps the drainage pipe in the guide 4 to move more smoothly. During production, a groove can be provided on the guide 4, the first roller 41 is sleeved on a shaft, and then the shaft is fixed to the corresponding position in the groove.

[0028] As Figure 1 shown, a first telescopic frame is provided on the first support plate 11. The first telescopic frame includes a first telescopic rod 15 arranged vertically, and a first receiving plate 16 is fixedly connected to the free end of the first telescopic frame. The first receiving plate 16 cooperates with the fixture 2 to fix the drainage pipe, raising the pipe and increasing the operating space for convenient construction. A second telescopic frame is provided on the second support plate 31. The second telescopic frame has the same structure as the first telescopic frame, including a second telescopic rod 35 and a second receiving plate 36. The second receiving plate 36 cooperates with the guide 4 to guide the drainage pipe. Raising the pipe increases the operating space for convenient construction. Scales can be provided on the telescopic rod, or directly set at different height positions, to facilitate visually determining the consistency of the height adjustment of the fixing part and the guiding part.

[0029] As Figure 4 described, a second roller 37 that can rotate around the central axis is provided on the second receiving plate 36. The second roller 37 is located on the center line of the guide 4, that is, the line passing through the center of the arc in the vertical direction of the guide 4, and has the same rotation direction as the first roller 41, and the second roller 37 is flush with the inner surface of the guide 4. This makes it more labor-saving for the pipe in the guide 4 to move.
