Description

Technical Field

[0001] The utility model belongs to the technical field of fire hoses, and in particular relates to an anti-lock winding device for a hose drying machine. Background Art

[0002] The fire hose drying machine is used to unfold and dry the cleaned fire hose and automatically reel it after drying. Most existing drying machines reel the hose by directly driving the reeling fork with a motor. In order to prevent the motor from running after the hose is reeled, a stop contact switch is often set near the reeling fork. For example, patent application CN210612755U discloses an automatic drying and reeling machine for fire hoses; another example is patent application CN116899163A discloses a hose drying and reeling machine. However, since the ends of the hoses to be dried all contain hose joints, in actual use, when the hoses hanging high are reeled, the hose joints at the bottom are easily stuck at the bottom of the reel, causing the hose to be unable to be reeled up, while the motor is still in normal operation at this time, which will cause the reeling fork to be overloaded and deformed, or even break the reeling fork or burn out due to overload of the motor. To this end, our company conducted research on the winding device and developed a winding device based on friction plates to achieve anti-lock braking. Although this device achieves the anti-lock function, the friction plate is easily worn, and the friction plate and driven plate need to be replaced regularly, resulting in high later use costs.

[0003] Therefore, a new technical solution is needed to solve the above technical problems. Utility Model Content

[0004] The purpose of the utility model is to provide an anti-lock winding device for a hose drying machine. The winding device is ingeniously provided with a driving disk fixedly connected to the motor driving shaft and a driven disk rotatably connected to the driving shaft through a bearing at the top. The driving disk drives the driven disk to perform winding action through the principle of magnets of the same charge repelling each other. When the hose is stuck, the pulling force of the hose is greater than the repulsive thrust of the magnet, and the driving disk is idle, while the driven disk does not rotate, which effectively avoids the overload of the driving disk and damages the motor or the winding fork. At the same time, a gap is left between the disc of the driving disk and the disc body of the driven disk, which avoids friction between the driving disk and the driven disk when the driving disk is idling, realizes zero-friction rotation, and improves the service life of parts.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An anti-lock winding device for a hose drying machine includes a driving disk and a driven disk. The bottom of the driving disk is in the shape of a disk, and the middle part of the driving disk is in the shape of a convex. The middle convex part of the driving disk is provided with a through hole for fixed connection with the driving shaft of the motor. The driven disk includes a disk body that matches the bottom disk of the driving disk, a connector inserted into the bottom of the middle convex part of the driving disk, and a fork body for winding the hose. The connector is fixedly connected to the bottom of the driving shaft through a bearing. A plurality of magnet blocks are provided on the bottom disk of the driving disk, and a plurality of magnet blocks corresponding to the positions of the magnet blocks on the driving disk are also provided on the disk body of the driven disk. The magnetism of the magnet blocks on the driving disk is the same as that of the magnet blocks on the driven disk. Furthermore, the driving disk is fixed to the driving shaft by a positioning pin.

[0007] Furthermore, the disk body of the active disk is provided with a plurality of countersunk holes for placing magnet blocks along the circumferential direction of the disk body. The disk body of the driven disk is provided with a plurality of countersunk holes for placing magnet blocks along the circumferential direction of the disk body.

[0008] Furthermore, the connecting body, the disc body and the fork body of the driven disc are an integrated structure.

[0009] Furthermore, a gap is left between the disk of the active disk and the disk body of the driven disk, and the gap is 0.01-2 mm.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] (1) The utility model adopts the structural design of the driving disk and the driven disk. The driving disk drives the driven disk to reel in the water hose through the force of the magnet block. When the water hose is stuck or the water hose is pulled, the pulling force of the water hose is greater than the repulsive thrust of the magnet. The driving disk realizes idling, while the driven disk is pulled by the water hose and does not rotate. This effectively avoids overloading of the driving disk and damage to the motor or the reeling fork.

[0012] (2) The utility model leaves a gap between the disk of the driving disk and the disk body of the driven disk, thereby avoiding friction between the driving disk and the driven disk when the driving disk is idling, achieving zero-friction rotation and improving the service life of parts.

[0020] The following examples are used to further illustrate the content of the utility model, but do not limit the application of the utility model.

[0021] like Figure 1 and Figure 2 As shown, an anti-lock winding device for a hose drying machine includes an active disk 1 and a driven disk 2. The bottom of the active disk 1 is in a disc shape (hereinafter referred to as the bottom disc 10 of the active disk), and the middle part of the active disk 1 is convex (hereinafter referred to as the middle convex part 3 of the active disk). The middle convex part 3 of the active disk is provided with a through hole 4 for fixed connection with a driving shaft 9 of a motor (not shown in the figure) (such as Figure 3 and Figure 4 as shown).

[0022] like Figure 5 and Figure 6 As shown, the driven disk 2 includes a disk body 5 matched with the bottom disk 10 of the driving disk, a connector 6 inserted into the bottom of the middle protrusion of the driving disk, and a fork body 7 for winding the water hose. In order to facilitate manufacturing and meet the strength requirements, the connector 6, the disk body 5 and the fork body 7 of the driven disk are an integrated structure. The connector 6 is fixedly connected to the bottom of the driving shaft 9 through a bearing 8. In order to facilitate fixation, it is fixed by a positioning pin 12. On the bottom disk 10 of the driving disk, there are a plurality of countersunk holes 13 for placing magnets 11 along the circumferential direction of the disk body. On the disk body 5 of the driving disk, there are a plurality of countersunk holes 13 for placing magnet blocks 11 along the circumferential direction of the disk body. The magnet blocks are now arranged correspondingly, and the magnetism of the magnet block 11 on the driving disk is the same as that of the magnet block 11 on the driven disk.

[0023] like Figure 2As shown, through the structural design of the active disk 1 and the driven disk 2, the active disk 1 is directly fixedly connected to the driving shaft 9 of the motor, and the driven disk 2 is movably connected to the end of the active shaft 9 through a bearing, that is, the driven disk can rotate freely on the active shaft, and the active disk 1 drives the driven disk 2 to reel in the principle of like-sex repulsion between magnets between the active disk 1 and the driven disk 2. The required driving force of the driven disk can be achieved by adjusting the magnetic force size and number of the magnet blocks. When the water hose is stuck or the water hose is pulled, the pulling force of the water hose is greater than the repulsive thrust of the magnet, and the active disk is idle, while the driven disk is pulled by the water hose and does not rotate, which effectively avoids the overload of the active disk to damage the motor or the reeling fork. At the same time, there is a gap between the disc of the active disk and the disc body of the driven disk, and the gap is generally set to 0.01-2mm. With such a structural design, the active disk and the driven disk are rotated with zero friction when idling, avoiding wear of parts. When the water hose can rise normally, under the thrust of the like-charged repulsion of the magnet block and driven by the active disk, the driven disk resumes rotation and continues to reel in. After the reeling is completed, the original switch on the drying machine is triggered and the motor stops working.
