Description

Technical Field

[0001] This utility model relates to the field of hose reel technology, specifically to a hose reel screw clamp device. Background Technology

[0002] Currently, in fire rescue and flood drainage operations, the laying and retrieval of water hoses still rely heavily on manual labor. However, for large-diameter (six inches and above) water hoses, the hoses themselves are quite heavy, so the intensity of manual labor is extremely high when laying them. Especially after the flood drainage operation is completed, when retrieving and winding the water hoses, it is necessary to squeeze out the residual water from the hoses before winding them up. This poses a challenge to the physical strength of the rescue personnel who have just completed the flood drainage operation.

[0003] Currently, after use, fire hoses need to be dewatered and rolled up using a hose reel. The process of rolling the hose into a roll requires a clamping device to control the clamping degree according to different customer requirements. However, existing clamping devices cannot automatically adjust the clamping force, making wrinkles prone to occur during the winding process. Therefore, we propose a hose reel screw clamping device to solve the above problems. Utility Model Content

[0005] The technical solution adopted by this utility model to solve its technical problem is: a screw clamp device for a water hose reel, including a drive bushing, there are two drive bushings, the outer walls of the two drive bushings are symmetrically installed on the water hose reel, a central spindle is movably connected to one end of each drive bushing, a movable hole is opened on the outer wall of one end of the central spindle, a chuck assembly is arranged inside the movable hole, a screw end cap is fixedly installed inside one end of the drive bushing, an adjusting screw is rotatably connected inside the screw end cap, a handwheel is fixedly connected to one end of the adjusting screw, and an adjusting nut is threadedly connected to the outer wall of one end of the adjusting screw;

[0006] By adopting the above technical solutions, the application areas are reflected in intelligent equipment for collecting water hoses, such as fire training, water rescue, flood control dikes, and farmland irrigation.

[0007] The chuck assembly includes a connecting mandrel, a movable groove, a central core plate, a clamping piece, and a side plate. One end of the connecting mandrel is fixedly connected to the inside of the movable hole. The movable groove is formed on one end of the connecting mandrel's outer wall. The central core plate is fixedly connected to one end of the connecting mandrel's outer wall. The clamping piece is fixedly connected to one end of the connecting mandrel's outer wall near the central core plate. The side plate is fixedly connected to one end of the connecting mandrel's outer wall near the clamping piece.

[0008] By adopting the above technical solution, drilling, cutting, and pre-processing are performed on the core board, clamping plates, and side plates. The special curved surface arc design algorithm is used to form the arc through turning to fit the external clamp design. Secondly, heat treatment is performed to improve the overall hardness and corrosion resistance, and the surface steel is painted black. Finally, assembly and testing are carried out to ensure that all parts of the fixture are properly connected and used.

[0009] Furthermore, an adjusting nut is fixedly connected to one end of the central spindle near the interior of the movable hole, and the outer wall of the adjusting nut is in contact with the inner wall of the drive shaft sleeve.

[0010] Furthermore, one end of the adjusting screw extends into the interior of the drive shaft sleeve, and the outer wall of one end of the adjusting screw is adapted to the interior of the movable hole and the movable groove.

[0011] Furthermore, the handwheel is located at one end of the drive shaft sleeve and the lead screw end cap.

[0012] Furthermore, the drive shaft sleeve, central spindle, chuck assembly, lead screw end cap, adjusting lead screw, handwheel, and adjusting nut are made of steel.

[0014] The beneficial effects of this utility model are:

[0015] The screw clamp device of this hose reel winding machine, by rotating two handwheels, drives the adjusting screw to rotate inside the screw end cover and the drive shaft sleeve. This causes the adjusting nut, which is threaded to the outer wall of one end of the adjusting screw, to move the central core shaft and the chuck assembly towards the center of the two clamps. This allows the central core plate, clamping plates, and side plates inside the symmetrical chuck assembly to press the hose tightly, thus preventing wrinkles during the winding process. At the same time, different degrees of clamping can be controlled according to different requirements. Attached Figure Description

One end of the connecting spindle 41 is fixedly connected to the interior of the movable hole 3. The movable groove 42 is formed on the outer wall of one end of the connecting spindle 41. The central core plate 43 is fixedly connected to the outer wall of one end of the connecting spindle 41. The clamping plate 44 is fixedly connected to the outer wall of one end of the connecting spindle 41 near the central core plate 43. The side plate 45 is fixedly connected to the outer wall of one end of the connecting spindle 41 near the clamping plate 44. By adopting the above technical solution, drilling, cutting curved surfaces, and pre-processing are performed on the central core plate 43, clamping plate 44, and side plate 45. A special curved surface arc design algorithm is used to form an arc through turning to fit the external clamp design. Secondly, heat treatment is performed to improve the overall hardness and corrosion resistance. The surface steel is then painted black. Finally, assembly and testing are carried out to ensure that all parts of the fixture are properly connected and used.

[0024] Reference Figure 2 , 3 As shown, an adjusting nut 8 is fixedly connected to one end of the central spindle 2 near the interior of the movable hole 3, and the outer wall of the adjusting nut 8 is in contact with the inner wall of the drive shaft sleeve 1.

[0025] Reference Figure 3As shown, one end of the adjusting screw 6 extends into the interior of the drive sleeve 1, and the outer wall of one end of the adjusting screw 6 is adapted to the interior of the movable hole 3 and the movable groove 42. By rotating the two handwheels, the handwheels drive the adjusting screw to rotate inside the screw end cover and the drive sleeve, so that the adjusting nut threaded to the outer wall of one end of the adjusting screw drives the central core shaft and the chuck assembly to move towards the center of the two clamps, so that the central core plate, clamping plate and side plate inside the symmetrical chuck assembly press the water hose tightly. In this way, no wrinkles will occur during the winding process, and different clamping degrees of the clamps can be controlled according to different requirements.

[0026] Reference Figure 1 , 3 As shown, the handwheel 7 is located at one end of the drive shaft sleeve 1 and the lead screw end cover 5.

[0027] Reference Figure 1-3 As shown, the drive sleeve 1, the central spindle 2, the chuck assembly 4, the lead screw end cover 5, the adjusting lead screw 6, the handwheel 7, and the adjusting nut 8 are made of steel. By adopting the above technical solution, when the adjusting lead screw 6 drives the adjusting nut 8 and the central spindle 2 to move to the other end of the drive sleeve 1, the protruding block on one side of the handwheel 7 is inserted into the groove on one side of the lead screw end cover 5.

[0028] During use, by turning the two handwheels, the handwheels drive the adjusting screw to rotate inside the screw end cover and the drive shaft sleeve. This causes the adjusting nut, which is threaded to the outer wall of one end of the adjusting screw, to move the central core shaft and the chuck assembly towards the center of the two clamps. This allows the central core plate, clamping plates, and side plates inside the symmetrical chuck assembly to press the water hose tightly, preventing wrinkles during the winding process. At the same time, different levels of clamping can be controlled according to different requirements.
