Description

Technical Field

[0001] The utility model belongs to the technical field of carat tube processing, and particularly relates to a carat tube hot-melt connection device. Background Art

[0002] Carat tube is hot winding tube, which is a winding structure wall tube. The wall tube is made of high-density polyethylene resin as the main raw material and adopts hot winding technology. A hot melt connection device is used when using carat tube.

[0003] The sockets and spigots of pipes produced by some manufacturers are not completely matched in length. The spigot is too long and the hot-melt connection process is not strictly controlled, which can easily cause the socket to be damaged; the spigot is too short and the hot-melt process is not strictly controlled, which can easily cause incomplete connection. After completion, it cannot meet the requirements of the closed water test and leakage will occur during use. At the same time, if there is no flat site at the construction site, the sockets and spigots at the hot-melt heads are not in a relatively horizontal position during the connection of the two carat pipes on the uneven site, which can easily cause defects such as misalignment and rupture. In addition, at the construction site, the carat pipe pulls the two pipe fittings during the hot-melt process, and cylindrical ropes or braided slings are mostly used as pulling force and fixing devices. This type of material can easily cause deformation or rupture of the carat pipe wall, resulting in a large number of defects during the endoscopy of the pipe network, thus affecting the quality of the project. Utility Model Content

[0006] Preferably, mounting blocks are movably mounted on both upper and lower sides of the fixed bracket, and a connecting support block and an extending support plate are fixedly connected to opposite sides of the two mounting blocks.

[0007] Preferably, an extension plate is fixedly connected to the front side of the connecting support block, the front end of the extension plate extends to the inner cavity of the extension support plate, and a threaded bolt is installed through the top of the extension support plate.

[0008] Preferably, the rolling cylinder is mounted on the surface of the connecting shaft through a steel ball bearing, and the connecting shaft can be selected to have different lengths according to the diameter of the carat tube body.

[0010] Preferably, the number of the lever hoists is two, and the number of the pulling hooks is six.

[0011] Preferably, a disc nut is provided on the rear side of the surface of the connecting shaft via a threaded movable sleeve, and the rolling cylinder adopts a hollow structure.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The utility model can effectively solve the problems of misalignment and cracking of the socket at the hot-melt joint caused by the unevenness of the construction site, and also effectively solve the problems of the socket not being in place during the on-site hot-melt connection due to the mismatch of the socket of the carat tube itself when it leaves the factory, or the socket being too deep, causing cracks in the joint, and also effectively solves the problems of the carat tube ribs turning over or the tube wall being dented when conventional ropes are tied, causing the pipe network to be deformed or cracked during endoscopic inspection.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-Figure 4 As shown, a carat tube hot-melt connection device includes a lever hoist 1 and a fixed bracket 4. The user first installs a rolling drum 6 on the fixed bracket 4 through a connecting shaft 5 so as to place the carat tube body 2 in the fixed bracket 4. Then, the user places the carat tube body 2 on the rolling drum 6. After completion, the user sets a fixing band 3 on the carat tube body 2. Then, the user connects the two ends of the lever hoist 1 with the fixing band 3 so that the carat tube body 2 can be pulled when hot-melting.

[0021] However, during hot-melt connection, it is usually impossible to ensure that the two carat tubes are connected on a flat surface. When connecting on an uneven surface, the socket at the hot-melt head is not in a relatively horizontal position, which can easily cause defects such as misalignment and rupture.

[0022] As a preferred embodiment of the carat tube hot-melt connection device of the utility model, Figure 2 and Figure 3 As shown, this embodiment provides a carat tube hot-melt connection device, including a lever block 1 and a fixing bracket 4. The user first places the carat tube on the rolling drum 6. After completion, the user then sets the fixing band 3 on the carat tube body 2, and then hooks the pulling hook 7 to the two ends of the carat tube body 2 to prevent the fixing band 3 from sliding. Then, the user connects the two ends of the lever block 1 with the fixing band 3, so that the carat tube body 2 can pull the carat tube body 2 during hot-melt. When the hot-melt connection pulls the two carat tube bodies 2 to move relative to each other, the user controls the socket distance of the two carat tube bodies 2 through the socket measuring ruler. When the measuring ruler reaches the pre-measured socket size, the lever block 1 is stopped from rotating.

[0023] When the above embodiment is implemented, the staff needs to adjust the spacing between the support components according to the model of the carat tube in advance to prevent the carat tube from being unstable during connection.

[0024] In some embodiments, Figure 3As shown, the user first installs the bottom connecting support block 8 and the extension support plate 9 on the fixed bracket 4 to increase the stability between the two fixed brackets 4. The user first adjusts the extension length of the extension plate 10 according to the spacing between the two fixed brackets 4. After the adjustment, the user tightens the threaded bolt 11 to fix the extension plate 10. At the same time, the user inserts the installation drawer block 12 into the fixed bracket 4 through the connecting support block 8 and the extension support plate 9. Then the user places the carat tube body 2 on the rolling drum 6, and then installs the top connecting support block 8 and the extension support plate 9 on the fixed bracket 4.

[0025] When the above embodiment is implemented, the stability of the connection between the two supporting components can be increased, thereby increasing the stability of the carat tube limit, and can also increase the stability of the placement of the supporting components. At the same time, the spacing of the supporting components can be adjusted according to the model of the carat tube, so that the connecting components can be adjusted according to the needs, thereby increasing the practicality of the equipment.

[0026] In some embodiments, the user first passes the connecting shaft 5 of the corresponding model through the inner cavity of the fixed bracket 4, and the connecting shaft 5 also installs the rolling cylinder 6 on the fixed bracket 4, so that during processing, it is convenient for the staff to place the carat tube body 2 into the fixed bracket 4.

[0027] When the above embodiment is implemented, when supporting carat tubes of different types, the support requirements can be met, so that the equipment can meet the processing requirements of carat tubes of different types.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
