Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting pipe processing, in particular to a fire-fighting pipe plastic coating turning machine. Background Art

[0002] The fire-fighting pipe is plastic-coated, with steel pipe as the base pipe, and the outer wall is coated with thermosetting powder coating with high adhesion, impact resistance, corrosion resistance and weather resistance, and the inner wall is coated with thermoplastic powder coating with high adhesion, corrosion resistance, food-grade hygiene. It adopts sandblasting and chemical double pre-treatment, preheating, internal coating, external coating, curing, post-treatment and other processes to make the water supply inner and outer plastic-coated composite steel pipe, which is a cost-effective product upgraded from traditional steel-plastic pipe and galvanized pipe.

[0003] Under existing conditions, in order to fix the fire hose with special shape, screws or splint clamping structures are mostly used. However, the existing clamping structures are mostly clamped from the outside to the inside, resulting in a blind area for spraying plastic on the outer wall of the fire hose. Thermosetting powder coating is manually applied to the surface of the fire hose. When it is manually turned over, it is difficult to control the degree of deflection, which can easily cause the fire hose to fall off, resulting in uneven coating and affecting the use of the fire hose. Utility Model Content

[0004] The utility model aims to solve the problem that the turning angle is difficult to control in the prior art, and proposes a fire-fighting pipe plastic coating turning machine.

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

[0006] A fire-fighting pipe plastic coating turning machine comprises a main body, a first driving motor is fixedly installed at the bottom end of the main body, a driving gear is keyed to the free end of the first driving motor, two sets of driven racks meshing with the driving gear are slidably installed in the main body, a clamping plate fixedly connected with the driven rack is slidably installed on the main body, a second driving motor is fixedly installed outside the clamping plate, and a fixing mechanism driven by the second driving motor and used to fix the fire-fighting pipe is installed in the clamping plate;

[0007] A support plate is welded on one of the clamping plates, a third drive motor is fixedly mounted on one side of the support plate, and a flipping mechanism driven by the third drive motor and used to flip the fire hose is arranged on the support plate.

[0008] Preferably, the two groups of driven racks are centrally symmetrically arranged on both sides of the driving gear.

[0009] Preferably, the fixing mechanism includes a turntable rotatably installed in the clamping disk, a slide groove is provided in the turntable, an output port corresponding to the slide groove is opened on the outside of the turntable, a tray matched with the output end of the second drive motor is rotatably installed in the turntable, a connecting rod is connected to the pin shaft on the tray, a slider connected to the pin shaft at the free end of the connecting rod is slidably installed in the slide groove, and a support rod for contacting the inner wall of the fire pipe is welded on the slider.

[0010] Preferably, the free end of the support rod is in an arc shape that fits the inner wall of the pipe, and one end of the connecting rod is eccentrically connected to the tray.

[0011] Preferably, the flipping mechanism includes a rotating shaft rotatably mounted on the support plate, and a guide plate is welded to the free end of the rotating shaft, a transmission rod eccentrically connected to the output end of the third drive motor is slidably mounted in the guide plate, a transmission gear is rotatably mounted on the guide plate, a buckle that interferes with the transmission gear is welded on the guide plate, a center shaft is welded on the transmission gear, and the free end of the center shaft is matched with the tray.

[0013] Compared with the prior art, the utility model has the following advantages:

[0014] 1. The utility model controls the rotation of the tray and pushes out the support rod through the connecting rod. At this time, the free end of the support rod will contact the inside of the fire pipe. While not hindering the plastic coating on the surface of the fire pipe, it can also fix one end of the fire pipe from the inside out to avoid the existence of a plastic spraying blind area on the outer wall of the fire pipe.

[0015] 2. The utility model controls the rotation of the transmission rod to drive the guide rod to swing with the rotation axis as the fulcrum, and the traction buckle moves the transmission gear to control the flipping angle. At the same time, the fixing mechanism at that location can also be controlled to fix one end of the fire hose. BRIEF DESCRIPTION OF THE DRAWINGS

The two groups of driven racks 4 are symmetrically arranged on both sides of the driving gear 3. When the driving gear 3 rotates, the driven racks 4 will slide in opposite directions in the main body 1, which is convenient for adjusting the distance according to the size of the fire pipe and is applicable to more specifications of fire pipes for plastic coating. A clamping disc 21 fixedly connected to the driven rack 4 is slidably installed on the main body 1. A second driving motor 5 is fixedly installed outside the clamping disc 21, and a fixing mechanism driven by the second driving motor 5 and used for fixing the fire pipe is installed inside the clamping disc 21;

When the tray 11 rotates, when the angles between the three connecting rods 12 are equal, the maximum movement range is reached. A slide block 13 pin-connected to the free end of the connecting rod 12 is slidably installed in the slide groove 9. A support rod 14 for abutting against the inner wall of the fire pipe is welded on the slide block 13. The free end of the support rod 14 is in an arc shape that fits the inner wall of the pipe, making the fixation more reliable. At the same time, a rubber pad is connected to the free end of the support rod 14, which plays a protective role in the inner wall of the fire pipe when supporting and fixing the fire pipe.

[0025] The flipping mechanism includes a rotating shaft 16 rotatably mounted on the support plate 6, and a guide plate 17 is welded to the free end of the rotating shaft 16, a transmission rod 15 eccentrically connected to the output end of the third drive motor 7 is slidably mounted in the guide plate 17, the transmission rod 15 is a Z-shaped structure, the groove opened on the guide plate 17 is larger than the movable range of the transmission rod 15, and the guide plate 17 will not collide with the connection with the clamping plate 21 when swinging, a transmission gear 18 is rotatably mounted on the guide plate 17, a buckle 19 that conflicts with the transmission gear 18 is welded on the guide plate 17, a center shaft 20 is welded on the transmission gear 18, and the free end of the center shaft 20 is matched and connected to the tray 11.

[0026] It should be noted that the specific models and specifications of the first drive motor 2, the second drive motor 5 and the third drive motor 7 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it is not repeated here.

[0029] The third drive motor 7 is turned on, the transmission rod 15 rotates to control the guide plate 17 to swing with the rotating shaft 16 as a fulcrum, the traction buckle 19 moves the transmission gear 18, and the central shaft 20 rotates to fix the other side of the fire hose;
