Description

Technical Field

[0001] The utility model relates to the technical field of reel coils, in particular to a reel coil auxiliary tensioning mechanism. Background Art

[0002] The existing publication number is CN215478914U, which is a traction winding device, comprising a frame, a turntable is rotatably connected to the frame, a reel is coaxially fixed to the turntable, a driving member for driving the turntable to rotate is arranged on the frame, a pressing member is adjustable along the radial direction of the reel on the turntable, and a pressing gap for pressing the PE pipe is formed between the pressing member and the reel. The present application helps to fix the PE pipe more firmly and stably, and the fixation is more convenient.

[0003] However, in actual production and use, when the cleaning area is changed, the high-pressure hose needs to move with the nozzle and be coiled and moved in a reel. During the coiling process, the hose has its own reinforcement layer woven with steel wire and the tube body has a certain degree of bending resistance. It is inevitable that the high-pressure hose will escape the restriction of the reel and cause entanglement, resulting in friction damage to the outer layer of the hose, and the tube body is sharply bent, tightened, twisted, squeezed, etc., causing damage to the tube body and affecting its service life. Frequent replacement increases costs and may also cause equipment and personnel accidents. The higher the pressure-bearing capacity of the high-pressure hose, the more steel wire layers it has, and the cleaning medium contained inside, which is more likely to occur this phenomenon, so it needs to be improved.

[0008] Compared with the prior art, the utility model is composed of a reel, an unpowered roller, and a support frame. The reel shaft is driven to rotate the reel to complete the reeling and releasing of the high-pressure hose. When the high-pressure hose passes through the unpowered roller, it will bend by about 10°.

[0010] Furthermore, the bearing assembly can ensure stable rotation of the transmission shaft, and the position of the reel can be effectively limited by the abutment disk and the connection disk, and synchronous rotation of the reel and the transmission shaft can be effectively ensured.

[0013] Preferably, two of the rotating shafts are located on one side of the high-pressure hose, and another rotating shaft is arranged on the other side of the high-pressure hose.

[0014] Furthermore, the movement of the high-pressure hose can be stably limited.

[0015] Preferably, the diameter of the second gear is larger than that of the first gear.

[0016] Furthermore, the rotation speed of the transmission shaft can be reduced so as to stably reel up the high-pressure hose.

[0017] The beneficial effects of the utility model are:

[0018] 1. The reel rotates to complete the winding and releasing of the high-pressure hose. When the high-pressure hose passes through the unpowered roller, it will bend about 10 degrees. The outer layer of the high-pressure hose drives the unpowered roller to rotate, achieving the damping effect of winding and releasing the high-pressure hose, so that the high-pressure hose can be tightly coiled in the unpowered roller, and the high-pressure hose can run smoothly back and forth;

[0019] 22. By using the reel to assist in tightening, the high-pressure hose can be smoothly and steadily retracted and released. This structure reduces the wear of the high-pressure hose, extends its service life and reduces costs, and more effectively ensures the normal operation of the cleaning mechanism and the safety of personnel.

The high-pressure hose 2 can be rolled up through the rotating shaft 31.

[0028] Reference Figure 1-3 The support frame 4 includes a base frame 41, and bearing assemblies 42 are fixed on both sides of the upper end of the base frame 41. A transmission shaft 43 is commonly provided between the two bearing assemblies 42.
