[0001] This invention relates to the field of gate rust removal technology, specifically to a traveling device for a gate rust removal machine elevator and its usage method. Background Technology

[0002] A lock is a box-shaped hydraulic structure used to ensure the smooth passage of ships and to concentrate water level differences in a waterway. For example, the Three Gorges double-line continuous five-stage lock is the main navigation facility of the Three Gorges Dam. A lock is generally equipped with multiple gates that work together. The gates are coated with a protective coating to ensure their long-term stable use. For example, the Three Gorges double-line five-stage lock has been operating safely and stably for nearly 20 years.

[0003] However, after long-term use, the surface coating of metal structures such as lock gates will gradually approach the design protection period, so rust removal is required. During rust removal, a gate rust removal machine and a matching elevator are used. The gate rust removal machine is used to remove rust from the gate, such as a sandblasting rust removal machine. It can be operated manually or automatically as needed. The elevator is used to transport the gate rust removal machine and the rust removal workers.

Detailed Implementation

[0067] Example 1:

[0068] like Figure 1 , 2 As shown in Figure 3, a traveling device for a gate rust removal machine elevator includes an elevator 101 and an elevator drive frame 102. The elevator 101 refers to the gate surface rust removal equipment and its connecting frame, that is, using an existing frame and then setting the existing gate rust removal equipment on the frame, or setting a rust removal work platform; the elevator drive frame 102 can use existing lifting equipment, such as using a motor to drive a winding drum, the winding drum is equipped with a steel rope, the steel rope is connected to the elevator 101, and the motor drives the winding drum to rotate and wind up and down the steel rope to complete the lifting of the elevator 101.

[0069] The elevator 101 is connected to a fixed frame 2, and the fixed frame 2 has a first wheel set 3 and a second wheel set 4 on both sides;

[0070] The first wheel group 3 and the second wheel group 4 on the same side are connected by the track 5 for transmission.

[0071] The fixed frame 2 is connected to the elevator 101 via the connecting plate 201.

[0072] During the up-and-down movement of the elevator 101, the track 5 always moves up and down close to the gate. The tracked movement can adapt to the unevenness of the gate surface and provide more stable walking support.

[0073] In the preferred embodiment, the mounting bracket 2 is equipped with a probe 7; the probe 7 is used to detect the travel path of the track 5; it can detect obstacles such as protrusions on the travel path in advance, providing data support for subsequent adjustment actions; the probe 7 is preferably a 3D scanning probe, which transmits the detection data to the control unit in an existing manner, and the control unit obtains the information of protrusions on the path based on the acquired data in an existing manner, so as to facilitate subsequent reactions.

[0074] In a further embodiment, the first wheel group 3 includes a plurality of first rollers 305, the fixing frame 2 is provided with a first movable groove 301, and the first movable groove 301 is provided with a bushing 302.

[0075] The first roller 305 is provided with a first rotating shaft 304, and the first rotating shaft 304 is connected to the bushing 302;

[0076] The first rotating shaft 304 is equipped with an angle sensor 303. The angle sensor 303 adopts an existing angle sensor and is detected, connected and controlled in an existing manner. The angle sensor 303 can accurately measure the rotation angle of the first roller 305 in order to calculate its moving distance.

[0077] The fixed frame 2 is equipped with a first electric push rod 306. The output end of the first electric push rod 306 is connected to the bushing 302. The first electric push rod 306 can be connected and controlled in the existing way.

[0078] By activating the first electric push rod 306, the bushing 302 can be moved, thereby moving the first rotating shaft 304 and the first roller 305, which can adjust the position of the first roller 305 according to the detected situation.

[0079] In a further embodiment, the second wheel group 4 includes a plurality of second rollers 404, the fixing frame 2 is provided with a second movable groove 401, and the second movable groove 401 is provided with a movable sleeve 402.

[0081] The fixed frame 2 is equipped with a second electric push rod 405, and the output end of the second electric push rod 405 is connected to the movable sleeve 402; the second electric push rod 405 can be connected and controlled in the existing way.

[0082] In use, by activating the second electric push rod 405, the movable sleeve 402 can be moved, thereby moving the second rotating shaft 403 and the second roller 404. The position of the second roller 404 can be adjusted, and it can cooperate with the first wheel set 3 to ensure the normal operation of the track 5 and adaptability to different road conditions.

[0083] The inner side of the track 5 is provided with several tooth grooves, and the circumferential surfaces of the first roller 305 and the second roller 404 are provided with tooth blocks that are adapted to the tooth grooves, thereby ensuring the transmission between the first roller 305, the second roller 404 and the track 5.

[0084] In a preferred embodiment, the surface of the track 5 is provided with a plurality of magnetic blocks 501, which are evenly spaced apart; this allows the track 5 to be tightly attached to the gate surface by magnetic force, increasing the stability and reliability of movement and preventing slippage during movement.

[0085] Example 2:

[0086] like Figure 8 As shown, the connecting plate 201 is provided with a threaded post 203 and a plurality of guide rods 202 on the side near the elevator 101, and the threaded post 203 and guide rods 202 slide through the elevator 101;

[0087] The guide rod 202 restricts the direction of movement of the connecting plate 201.

[0088] The elevator 101 is equipped with a worm gear 206, which is threaded to the outside of the threaded post 203;

[0089] The elevator 101 is equipped with a second motor 603. The output shaft of the second motor 603 is equipped with a worm gear 205, which meshes with a worm wheel 206. The second motor 603 is preferably a servo motor or a stepper motor, which allows for connection and control in the existing manner.

[0090] Starting the second motor 603 can drive the worm gear 205 to rotate, which in turn drives the worm wheel 206 to rotate, thereby moving the threaded column 203, which in turn moves the connecting plate 201 and the fixed frame 2, so as to adjust the distance between the elevator 101 and the gate to adapt to different usage conditions.

[0091] Example 3:

[0092] like Figure 3 As shown, the fixing frame 2 is also equipped with a stabilizing mechanism 6 for fixing the elevator 101 after it stops;

[0093] The stabilizing mechanism 6 includes a movable seat 601 that is slidably connected inside the fixed frame 2. A first electromagnet 602 is provided on the side of the movable seat 601 away from the elevator 101.

[0094] The fixed frame 2 is equipped with a first motor 603. The output shaft of the first motor 603 is equipped with a threaded rod 604. The threaded rod 604 extends into the interior of the movable seat 601 and is threadedly connected to the movable seat 601. The first motor 603 is preferably a servo motor or a stepper motor, which allows for connection and control in the existing manner.

[0095] When in use, the first motor 603 is started to drive the threaded rod 604 to rotate, which drives the movable seat 601 to move, so that the first electromagnet 602 is attracted to the gate. Then the first electromagnet 602 is started to make the first electromagnet 602 firmly attracted to the gate, so as to achieve stable fixation after the elevator 101 stops.

[0096] Example 4:

[0097] like Figure 4 , 5 As shown in Figures 6 and 7, the fixed frame 2 is provided with a stabilizing mechanism 8, which is used to maintain the stability of the fixed frame 2 during movement.

[0098] The stabilizing mechanism 8 includes multiple connecting blocks 801 disposed on the inner wall of the track 5, and a second electromagnet 810 is disposed in the connecting block 801;

[0099] The circumferential surfaces of the first roller 305 and the second roller 404 are provided with movable grooves 802, the width of which is greater than the diameter of the connecting block 801.

[0100] In a preferred embodiment, the first roller 305 is composed of two roller pieces, with a movable groove 802 formed between the two roller pieces. The movable groove 802 is used for the passage of the connecting block 801, so that the connecting block 801 will not come into contact with the first roller 305 and the second roller 404 when the track 5 is moving.

[0101] The first rotating shaft 304 is externally provided with a connecting sleeve 803, the connecting sleeve 803 is provided with a fixing rod 804, the fixing rod 804 is provided with multiple connecting rods 805, and the fixing rod 804 is provided with a fixing sleeve 806 through the connecting rods 805;

[0102] The fixed sleeve 806 has a connecting groove 807 on the side near the track 5. When the track 5 rotates, it can drive the connecting block 801 through the connecting groove 807.

[0103] The inner wall of the connecting groove 807 is provided with a first electrical contact piece 808, and the connecting block 801 is provided with a second electrical contact piece 809; when the connecting block 801 is located in the connecting groove 807, the first electrical contact piece 808 and the second electrical contact piece 809 are electrically connected.

[0104] The fixing rod 804 and the connecting rod 805 are provided with wire holes 811;

[0105] The first contact piece 808 is connected to an existing power source via a connecting wire 812, and the second contact piece 809 and the second electromagnet 810 are connected to an external power source via a connecting wire 812.

[0106] During the lifting process of the elevator 101, the track 5 rotates, which drives the connecting block 801 to move. When the connecting block 801 moves close to the gate, it will move into the connecting groove 807. At this time, the second contact piece 809 of the connecting block 801 will contact the first contact piece 808. The circuit is then connected, and the second electromagnet 810 is energized and works. At this time, it can generate a magnetic force to tightly attract the gate, thereby stabilizing the elevator 101 during the lifting process.

[0107] After the connecting block 801 moves away from the connecting slot 807, the corresponding second contact piece 809 separates from the first contact piece 808, thus no longer generating magnetic force. Therefore, during operation, only the second electromagnet 810 near the gate works to complete the adsorption function, while the second electromagnets 810 in other positions do not work. This avoids the second electromagnets 810 in other positions from causing adverse effects on other equipment. Furthermore, as the connecting block 801 moves away from the gate, the corresponding second electromagnet 810 is de-energized, thus not affecting the connecting block 801 moving away from the gate, ensuring stability and smoothness during the movement.

[0112] S3. Calculate the moving distance S of the first roller 305 based on the rotation angle, the diameter D of the first roller 305 and the track thickness d;

[0113] ;

[0114] Where α0 represents the angle recorded by the angle sensor 303 when L is detected;

[0115] S4. When the first roller 305 moves close to L, the first electric push rod 306 drives the first roller 305 to move H.

[0116] S5. After the first roller 305 continues to move along the gate for M, the first electric push rod 306 resets, driving the first roller 305 to reset and continue normal walking motion.

[0117] S6. The first roller 305 continues to rotate with the lifting and lowering of the fixed frame 2; maintaining the continuous operation of the walking device and preparing to deal with the next possible protrusion or obstacle.

[0118] In the preferred embodiment, the track 5 always moves close to the gate, and the track 5 is attached to the gate by a magnet; this ensures stability and adhesion during movement.

[0119] Each first roller 305 independently calculates L, which can be precisely adjusted according to the roller conditions at different positions to adapt to the complex conditions of the gate surface;

[0120] After the elevator 101 stops moving, the following steps are included:

[0121] S71. The first motor 603 starts, driving the threaded rod 604 to rotate;

[0122] S72, the movable seat 601 moves toward the gate;

[0123] S73, the first electromagnet 602 touches the gate, and the first motor 603 stops moving;

[0124] S74. The first electromagnet 602 is activated, tightly adhering to the gate; this ensures the stable fixation of the elevator 101 after it stops, preventing the elevator from shaking or shifting due to external forces or other factors, and ensuring the safety and stability of subsequent operations.

[0125] The above method can improve the stability of the elevator 101 during lifting, so as to facilitate the rust removal work of the gate.

[0126] The above embodiments are merely preferred technical solutions of the present invention and should not be considered as limitations on the present invention. The scope of protection of the present invention should be limited to the technical solutions described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the scope of protection of the present invention.
