For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.
[0026] The utility model will be further described in detail below in combination with examples.
[0027] The utility model provides a specific embodiment of water conservancy underground powerhouse vent hole inner wall rust removal machine tool:
[0028] Please refer to Figures 1-6 , water conservancy underground powerhouse vent hole inner wall rust removal machine tool, including vertical rotating drum 1 and drive rotating drum 1 and connect on the upper side of rotating drum 1 motor 3, rotating drum 1 outside is provided with steel wire brush 2, and steel wire brush 2 includes several layers of steel wire connected with rotating drum 1;The output shaft of motor 3 is connected with rotating drum 1, when the output shaft of motor 3 rotates, drives rotating drum 1 and steel wire brush 2 high-speed rotation grinding, and the end of steel wire polishes and removes rust on vent hole wall 11.
[0029] In some examples, rotating drum 1 and the output shaft of motor 3 are connected by bolts. For different vent hole wall 11 inner diameters, select steel wire brush 2 slightly larger than vent hole wall 11 inner diameter.
[0030] The upper side of motor 3 is connected with lifting structure, and the lifting structure includes traction rope 4, winding drum 6 for winding and unwinding traction rope 4, triangular support hanger 5 for supporting the rotation of winding drum 6 and rocker 8 for driving the rotation of winding drum 6.
[0031] Before rust removal, open the vent cap, and place the triangular support hanger 5 on the upper periphery of the vent. The staff evenly shakes the rocker 8 to rotate the drum 6, and the rotation of the drum 6 can realize the winding and unwinding of the traction rope 4. The traction rope 4 is selected from a steel wire rope. When the drum 6 releases the traction rope 4, the motor 3 and the steel wire brush 2 descend along the inner side of the vent wall 11 under the gravity of the motor 3, and when the drum 6 winds the traction rope 4, the traction rope 4 moves upward to overcome the gravity of the motor 3 and the steel wire brush 2 to make the motor 3 and the steel wire brush 2 rise, and the rotation of the steel wire brush 2 realizes the polishing and rust removal.
[0032] When rust removal, the switch controlling the motor 3 must be set on the upper end of the vent outside, and the switch is prohibited to be set on the motor 3 to prevent the high-speed rotating motor 3 from hurting people; according to the depth of the vent, the traction rope 4 and the wire are configured to be long enough.
[0033] The machine has simple structure, is convenient and practical, easy to operate, high flexibility, and can effectively eliminate the rust problem and hidden danger of the vent wall 11.
[0034] The rocker 8 and the drum 6 are rotatably installed on the triangular support hanger 5; the rotation center line of the rocker 8 is parallel to the rotation center line of the drum 6, and one end of the rocker 8 and the drum 6 is provided with a gear 7 that meshes with each other, and in the embodiment, two gears 7 that are different in size are included, and the outer diameter of the gear 7 at the end of the rocker 8 is smaller than that of the gear 7 at the end of the drum 6; the smaller gear 7 drives the larger gear 7 to realize labor-saving driving and reduce the labor intensity of manual lifting.
[0035] The triangular support hanger 5 is rotatably installed with a ratchet pawl 9 that limits the reverse rotation of the gear 7, and in the embodiment, the ratchet pawl 9 is located on one side of the gear 7 at the end of the rocker 8, and the tail end of the ratchet pawl 9 extends into the teeth of the gear 7; when the motor 3 is lifted, the ratchet pawl 9 does not affect the rotation of the gear 7, and when the motor 3 descends, the ratchet pawl 9 limits the rotation of the gear 7, so when the motor 3 needs to descend, the ratchet pawl 9 needs to be manually lifted to separate the tail end of the ratchet pawl 9 from the gear 7; when the ratchet pawl 9 is loosened, the tail end of the ratchet pawl 9 moves downward under the action of gravity and enters the teeth of the gear 7, at this time, the line between the rotation center of the gear 7 and the rotation center of the ratchet pawl 9 has a certain angle with the ratchet pawl 9, and the gear 7 cannot be reversed, and the positive rotation can change the angle of the ratchet pawl 9 by overcoming the gravity of the ratchet pawl 9, so that safety accidents caused by accidental falling of the motor 3 can be avoided.
[0036] In other embodiments, a ratchet wheel can be provided at the end of the rocker 8 to cooperate with the ratchet pawl 9.
[0037] When the motor 3 drives the steel wire brush 2 to rotate, due to the friction between the steel wire brush 2 and the vent wall 11, especially when the friction resistance is large, the motor 3 and the traction rope 4 are flexibly connected, which can cause the motor 3 stator part to rotate, and further cause the traction rope 4 to twist.
[0038] Therefore, in the embodiment, the motor 3 stator part upper outer side is provided with an anti-twist structure 10; the anti-twist structure 10 comprises a ring-shaped seat 101 connected to the upper outer side of the motor 3, a plurality of swing rods 103 are evenly hinged on the outer ring side circumference of the ring-shaped seat 101, an elastic member is connected between the swing rod 103 and the ring-shaped seat 101, the elastic member makes the end of the swing rod 103 adhere to the vent hole wall 11; the outer ring side of the ring-shaped seat 101 is provided with a groove 102, the inner end of the swing rod 103 is hinged in the groove 102; the elastic member is a V-shaped elastic sheet 104, the two ends of the elastic sheet 104 are respectively connected with the swing rod 103 and the inner wall of the groove 102. In other embodiments, a torsion spring can be installed at the hinge of the swing rod 103 to replace the function of the elastic sheet 104.
[0039] When the motor 3 rises or falls under the action of gravity, the swing rod 103 can compress the elastic sheet 104, and the motor 3 and the steel wire brush 2 can rise and fall under the action of gravity.
[0040] When the steel wire brush 2 rubs rust and generates excessive resistance with the vent hole wall 11; the upper part of the motor 3 reverses relative to its output shaft, the motor 3 stator part drives the anti-twist structure 10 to rotate, such as Figure 5 The perspective counterclockwise rotates, the end of the swing rod 103 and the vent hole wall 11 rub to make the swing rod 103 tend to open, increase the outer diameter of the anti-twist structure 10, increase the acting force and friction force of the swing rod 103 and the vent hole wall 11, so as to realize braking, limit the rotation of the motor 3 stator part and the torsion of the traction rope 4.
[0041] Finally, it should be noted that the above only for the preferred embodiments of the present application, and not for limiting the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it still can be modified without paying creative labor for the technical solutions recorded in the foregoing embodiments, or equivalent replacement for some technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
