DETAILED DESCRIPTION OF THE EMBODIMENTS
[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model.
[0019] Please refer to Figures 1-6, the present utility model provides a technical solution: an internal lifting device for a wind power tower, including a slideway 1 and a lifting bucket 2. The slideway 1 includes two C-shaped steels with openings facing outwards. A plurality of cross beams 18 are fixedly connected between the two C-shaped steels to form a ladder for people to climb. On one side surface of the lifting bucket 2, a fixed wheel frame 3 and an adjusting wheel frame 4 are arranged in parallel. The fixed wheel frame 3 is fixedly connected to the lifting bucket 2, and the adjusting wheel frame 4 is slidably connected to the lifting bucket 2. The distance between the adjusting wheel frame 4 and the fixed wheel frame 3 can be adjusted. A pair of pulleys 5 are respectively arranged on the fixed wheel frame 3 and the adjusting wheel frame 4. The pulleys 5 slide in the notches of the C-shaped steel to realize the front-back direction limit of the lifting bucket 2. Free-rotating limit wheels 6 are arranged on both the fixed wheel frame 3 and the adjusting wheel frame 4. The limit wheels 6 are in contact with the outer side of the C-shaped steel to realize the left-right direction limit of the lifting bucket 2. By moving the adjusting wheel frame 4 away from the fixed wheel frame 3, one side of the pulley 5 can be removed from the notch of the C-shaped steel, so as to separate the lifting bucket 2 from the slideway 1. A rack 9 is fixedly arranged on the slideway 1. A worm gear 7 is rotatably arranged on one side surface of the lifting bucket 2. A gear 8 is fixedly installed on one side of the worm gear 7. The gear 8 meshes with the rack 9. A motor 10 is fixedly arranged in the lifting bucket 2. A worm 11 meshing with the worm gear 7 is fixedly installed at the power output end of the motor 10. The worm 11 is rotated by the motor 10, the gear 8 is rotated by the worm 11 meshing with the worm gear 7, and the lifting bucket 2 is lifted or lowered by the gear 8 meshing with the rack 9. The lifting and lowering of the lifting bucket 2 are controlled by changing the rotation direction of the motor 10. When the helix angle of the worm 11 is less than the friction angle between the worm and the worm gear, the worm and worm gear mechanism has self-locking property. The self-locking condition formed by the worm gear 7 and the worm 11 can prevent the lifting bucket 2 from descending due to the power failure of the motor 10, improving the safety of the lifting bucket 2. A pair of slide rails 12 are fixedly arranged on one side surface of the lifting bucket 2. The adjusting wheel frame 4 slides on the pair of slide rails 12. A screw 13 is installed in the adjusting wheel frame 4. The screw 13 can be screwed into the lifting bucket 2. When the screw 13 is screwed into the lifting bucket 2, the adjusting wheel frame 4 cannot move. A control console 14 and a storage battery 15 are fixedly arranged in the lifting bucket 2. The storage battery 15 supplies power to the motor 10, and the positive and negative rotation of the motor 10 is controlled through the control console 14, so as to control the lifting or lowering of the lifting bucket 2. A pair of moving wheels 17 are installed on one side of the bottom of the lifting bucket 2, and a handle 16 is installed on one side of the top of the lifting bucket 2. When the lifting bucket 2 is removed, the moving wheels 17 at the bottom facilitate the movement of the lifting bucket 2 on the ground, and the handle 16 facilitates the pulling of the lifting bucket 2. The slideway 1 is fixedly installed with a plurality of connecting plates 19 for connecting the tower barrel of the power generation tower.
[0020] Persons skilled in the art shall connect all the electrical components in this case to their adapted power supplies through wires, and should select a suitable controller according to the actual situation to meet the control requirements. For the specific connection and control sequence, reference shall be made to the sequence of operations among the electrical components in the following working principle to complete the electrical connection. The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, and no further description of electrical control will be given.
[0021] The working principle and usage process of the present utility model: When in use, the user stands in the lifting bucket 2 and controls the forward and reverse rotation of the motor 10 through the console 14 to realize the ascent or descent of the lifting bucket 2; when it is necessary to remove the lifting bucket 2, unscrew the screw 13 so that the adjusting wheel frame 4 can move on the slide rail 12. By pushing the adjusting wheel frame 4 to the side away from the fixed wheel frame 3, the pulley 5 can be moved out of the notch of the C-shaped steel, and at the same time the limit wheel 6 also moves away from the C-shaped steel. At this time, the lifting bucket 2 loses the left and right direction limits and can be removed from the slideway 1; the user pulls the handle 16 and can pull the lifting bucket 2 to move with the help of the moving wheel 17; when reinstalling, first insert the pulley 5 on the fixed wheel frame 3 into the notch of one side of the C-shaped steel, then attach the gear 8 to the rack 9, push the adjusting wheel frame 4 to insert the pulley 5 into the notch of the other side of the C-shaped steel, and at the same time ensure that the limit wheels 6 on both sides are tightly attached to the outside of the C-shaped steel. Finally, use the screw 13 to fix the adjusting wheel frame 4 on the lifting bucket 2 to complete the connection between the lifting bucket 2 and the slideway 1.
[0022] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
