Description

Technical area

[0001] The present invention relates to the technical field of derusting on platforms of high-speed railway stations, in particular to an automatic column derusting device and an automatic derusting method using high-pressure water jet columns. State of the art

[0002] Currently, the grinding and derusting of the platforms of the domestic high-speed railway station uses a mixed operation method of manned hoists and labor. This method has the following disadvantages: First, manual labor is labor-intensive, the construction cycle is long, and maintenance costs are high; second, workers must carry tools when working at heights, which poses a potential risk to safety at heights. Third, dust generated during work or harmful substances such as phenyl in paints can easily cause lung and eye diseases, and workers' health is not protected.

[0003] Most of the pillars of the high-speed train station building are made of steel structures. During the use of the high-speed station building, problems with peeling surface coatings and defects, as well as rust and corrosion, occur on the platform pillars. This not only seriously affects the overall aesthetics of the station building but also poses a major potential safety hazard. Routine maintenance and repair of the pillars is an integral part of the maintenance work on the high-speed train platforms.

[0004] The maintenance of platform columns has the following characteristics: (1) the column maintenance position is high above the ground; (2) the space and location of the platform are limited, and access to the site for large lifting equipment is restricted; (3) the time for each maintenance operation is short, with only a single time window (4 hours). These characteristics make column maintenance using manual tools and lifting equipment very dangerous and inefficient, and does not meet daily maintenance requirements. In the prior art, as described in the invention patent publication number CN 1 11 745 519 A and the utility model publication number CN 2 12 947 131 U, the device for grinding and derusting the columns of the platform canopies consists of an arched skeleton and a guide wheel rod assembly.The arch frame clamps the device to the column using a hydraulic cylinder, and the column is ground using a grinding device on the arch frame. Rust removal from the columns is achieved by mechanical grinding.However, there are some shortcomings: the circumferential rotation of the derusting device is a passive mechanism, which cannot ensure that the entire surface of the column is not missed during operation; the grinding device relies on the pressure on the surface of the column for grinding, which cannot be dynamically adjusted during the working process, and cannot remove the corrosion that is not in the same plane on the grinding surface; the rail movement structure should be realized to drive the derusting equipment to move along the surface of the column, and the rails should be in a certain compression with the surface of the column, so that the rail movement structure can drive the derusting device to move up and down along the column.Since this function conflicts with the need for the grinding device to lean against the column, it cannot be ensured that the compressive force of both is met at the same time, resulting in the column derusting device being unable to meet the design requirements.

[0005] For this reason, an automatic derusting device that is more efficient and can adapt to higher work intensity is urgently needed. CN 1 15 569 904 A concerns a column-climbing derusting robot. CN 2 16 095 077 U concerns a special cleaning device for a wind turbine tower drum-climbing robot. CN 1 16 428 137 A concerns an automatic cleaning device for a fan drum. Content of the invention

[0006] The present invention provides an automatic derusting device for platform columns of high-speed railway stations, which enables automatic derusting of the platform columns. The present invention solves the safety problems of personnel working at height, as well as the problems of high labor intensity, low work efficiency, and unprotected health of the operating personnel.

[0007] In view of the above-mentioned disadvantages of the prior art, it is an object of the present invention to provide an automatic column derusting apparatus and an automatic column derusting method using high pressure water jets.

[0008] To achieve the above-mentioned purposes and other related purposes, the present invention provides an automatic column rust removal apparatus according to claim 1 and an automatic column rust removal method using high pressure water jets according to claim 3.

[0009] In an optional embodiment of the present invention, in step SI, the clamping and releasing of the clamping device is carried out by driving a slide module unit in order to achieve clamping and releasing of the column.

[0010] In an optional embodiment of the present invention, in step S2, a servo motor is used to connect a planetary gear, wherein the planetary gear is connected to a worm gear, wherein the worm gear is provided with rubber wheels to drive the lifting and lowering of the climbing robot.

[0011] In an optional embodiment of the present invention, the rotary platform comprises two semicircular gear rings and two semicircular guide rails.

[0012] In an optional embodiment of the present invention, high pressure water from a high pressure pump group impacts the column through a nozzle to remove the rust.

[0013] In an optional embodiment of the present invention, the cleaning disc is driven by the rotation of a gear and thus rotated 360° on the circular guide rails.

[0014] In an optional embodiment of the present invention, the climbing robot comprises electrical control technology and sensor detection technology. (1) After the device is clamped to the column, the lifting and rotating mechanisms perform their corresponding functions. During each derusting cycle, the lowering path of the lifting mechanism is coordinated with the cleaning area of ​​the rotating cleaning disc to ensure that no area is missed. The lowering of the lifting mechanism and the rotating function of the rotating mechanism are detected and controlled by sensors, so there is no time conflict between the two function operators, ensuring that no derusting area is missed. (2) High-pressure water jet is used for derusting. The nozzle does not need to touch the column surface, and the flood jet is used for derusting. By adjusting the high-pressure water pressure and the distance of the nozzle from the column, the required derusting can be achieved across the entire surface. (3) The clamping mechanism and the descaling mechanism are relatively independent, and there is no conflict between the clamping force required by the two mechanisms, which can meet the requirements of more working conditions.

[0015] In the following, embodiments of the present invention will be described using concrete examples. Those skilled in the art can easily understand the further advantages and effects of the present invention from the information in this description. The present invention can also be implemented or applied in various other specific embodiments, and various details in this description can also be modified or changed in various ways based on different views and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features can be combined with each other in the embodiments without conflict.

[0016] It should be noted that the drawings shown in the following embodiments only schematically illustrate the basic concept of the present invention, and the drawings only show the components related to the present invention and are not drawn in accordance with the number, shape, and size of the components in actual implementation. The actual implementation of the components, the number and ratio of the components may be arbitrarily changed, and the layout of the components may be more complex. This technical solution mainly consists of two parts: a climbing robot and a high-pressure pump group 1, where the high-pressure pump group 1 is a high-pressure water jet pump group.The high-pressure water jet pump group is connected to the cleaning mechanism of the climbing robot via a high-pressure water pipe to provide power for cleaning and derusting the columns. The climbing robot can perform the functions of clamping, climbing, rotating, and cleaning the columns. The climbing robot is mounted on the column by a gripper wheel set, with the lifting carriage remaining constantly at the cleaning height after a certain travel distance. The vertical carriage is equipped with a rotating rail on which the high-pressure water nozzle can rotate. The rotation of the nozzle cleans the outer surface of the column. The electrical system 8 is configured remotely, and the automatic derusting process of the column can be controlled and operated via the control panel of the electrical system 8.

[0017] The automatic column rust removal device with high-pressure water jet uses electrical control technology and sensor identification technology, which significantly shortens the work cycle and improves work efficiency. The automated workflow includes the following.

[0018] As can be seen from these technical solutions of the invention, in the invention, the clamping and release of the clamping device are carried out by driving a slider module unit to achieve clamping and release of the column; the climbing mechanism is mounted on the frame and uses a servo motor connected to a planetary gear train; the planetary gear train is connected to a worm gear train. The worm gear train is provided with rubber wheels to drive the lifting and lowering of the climbing robot; the climbing robot is designed to be equipped with two semicircular gear rings with two semicircular guide rails that form a rotating platform. The circular guide rail is provided with three sliding seats on which the large rotating cleaning discs are mounted.The rotary drive uses a servo motor connected to a planetary gear, which is connected to a pinion that meshes with a large ring gear. The rotation of the gears drives the cleaning disc 360° on a circular guide rail, allowing the column to be cleaned circumferentially. The large rotating cleaning disc is equipped with a high-pressure nozzle, and high-pressure water from the high-pressure pump group impacts the column through a nozzle to remove rust. The climbing robot uses electrical control technology and sensor detection technology to realize fully automatic control of the clamping device: clamping → clamp detection → rising height detection → opening of the high-pressure pump set → rotating the large cleaning disc → lowering to the specified height → shutting down, which significantly shortens the work cycle and improves work efficiency.

[0019] An automatic column derusting device with high-pressure water jet is used, which achieves a multifunctional combination and electric automatic control; the compact structure and convenient operation make it possible to facilitate the derusting of columns and improve the efficiency and safety of operation.

[0020] As in the Fig. 1 to 2, the automatic column rust removal apparatus with high pressure water jet in this embodiment includes a high pressure pump group 1, a high pressure piping 2, a clamping mechanism 3, a lifting mechanism 4, a rotating mechanism 5, a cleaning mechanism 6, and an electrical system 8.

[0021] As in Fig. As shown in Figure 3, the clamping mechanism 3 consists of four sets of identical clamping assemblies 3-3 connected by slide connectors 3-4. Each clamping assembly has a servo motor 3-1, a planetary gear 3-2, a guide rail slide 3-3, and a positioning pin 3-5. The lifting mechanism 4 is connected to the guide rail slide 3-3 via a connecting rod. The servo motor 3-1 and the planetary gear 3-2 on the guide rail slide drive the slider on the guide rail slide to move, causing the lifting mechanism to move left and right, so that the rubber wheels press against the columns to achieve the clamping function.

[0022] As in Fig. As shown in Figure 4, the lifting mechanism 4 includes a worm gear 4-1, a planetary gear 4-2, a servo motor 4-3, an auxiliary rubber wheel 4-4, and a rubber wheel 4-5. The servo motor 4-3 is connected to the planetary gear 4-2, and the planetary gear 4-2 is connected to the worm gear 4-1. The worm gear 4-1 is equipped with a set of figure-eight rubber wheels 4-5 and a set of small auxiliary rubber wheels 4-4 to ensure that the robot does not tip over while walking. The clamping mechanism generates friction between the rubber wheel set and the column during clamping, while the servo motor provides the driving force for the robot's lifting and crawling.

[0023] As in Fig. As shown in Figure 5, the rotating mechanism includes a servo motor (5-1), a planetary gear (5-2), a gear (5-3), a sliding seat (5-4), a gear ring (5-5), a circular arc guide (5-6), a large cleaning disc (5-7), and a high-pressure nozzle (5-8). Two semicircular gear rings 5-5 and two semicircular guide rails 5-6 form the rotating platform. The circular guide rail 5-6 is provided with three sliding seats 5-4 on which the large rotating cleaning discs are mounted. The rotating drive uses a servo motor 5-1 connected to a planetary gear 5-2, with the planetary gear connected to a pinion 5-3 that meshes with the sliding seat 5-4. The rotation of the gears drives the cleaning disc 5-7 360° on a circular guide rail 5-6, allowing the column to be cleaned circumferentially.

[0024] The large rotating cleaning disc 5-7 is equipped with a high-pressure nozzle 5-8, whereby the high-pressure water from the high-pressure pump group bounces through a nozzle against the column to remove the rust.

[0025] As in Fig. As shown in Figure 6, the automatic column rust removal device with high-pressure water jet is equipped with an electrical system 8, sensors, and other components. Through electrical control technology and sensor detection technology, fully automatic control is achieved, i.e., clamping the column clamping device → rising height detection → rotating the cleaning mechanism → cleaning and derusting → downward cleaning section → rotating the cleaning mechanism → cleaning and descaling → releasing the clamping device.

[0026] From the above description, it can be seen that the invention fulfills the functions of clamping, climbing, rotating, and automated operation of the platform column. This improves efficiency, increases safety, and reduces the labor intensity of the personnel.

[0027] After the device is clamped to the column, the lifting and rotating mechanisms perform their respective functions. During each derusting cycle, the lowering path of the lifting mechanism is coordinated with the cleaning area of ​​the rotating cleaning disc to ensure that no area is missed. The lowering of the lifting mechanism and the rotating function of the rotating mechanism are detected and controlled by sensors, ensuring that there is no time conflict between the two function operators, ensuring that no derusting area is missed. High-pressure water jets are used for derusting; the nozzle does not need to touch the surface of the column, and flood jets perform derusting.By adjusting the high-pressure water pressure and the distance of the nozzle from the column, the need for rust removal in the entire area can be realized; the clamping mechanism and the descaling mechanism are relatively independent, and there is no conflict between the clamping force required by the two mechanisms, which can meet the requirements of more working conditions.

[0028] The automatic column rust removal device with high-pressure water jet comprises a high-pressure pump group 1, a high-pressure piping 2, a clamping mechanism 3, a lifting mechanism 4, a rotating mechanism 5, a cleaning mechanism 6, and an electrical system 8; wherein the clamping mechanism 3 is connected by a clamping assembly 3-3 via a slide connector 3-4, the clamping assembly 3-3 comprising a servo motor 3-1, a planetary gear 3-2, a guide slide 3-3, and a positioning pin 3-5; wherein the lifting mechanism 4 comprises a worm gear 4-1, a planetary gear 4-2, a servo motor 4-3, an auxiliary rubber wheel 4-4, and a rubber wheel 4-5;wherein the rotating mechanism 5 comprises a servo motor 5-1, a planetary gear 5-2, a gear 5-3, a sliding seat 5-4, a gear ring 5-5, a circular guide rail 5-6, a large cleaning disk 5-7, and a high-pressure nozzle 5-8, wherein the servo motor 5-1 is connected to a planetary gear 5-2, the planetary gear 5-2 is connected to a gear 5-3, and the gear 5-3 is engaged with a sliding holder 5-4;

[0029] The number of clamping devices 3-3 is four. The servo motor 4-3 is connected to the planetary gear 4-2. The planetary gear 4-2 is connected to the worm gear 4-1. The four sets of clamping assemblies 3-3 are located on opposite sides of the lifting mechanism 4. The high-pressure pump group 1 is a high-pressure water jet pump group. The high-pressure nozzles 5-8 are provided in the large cleaning discs 5-7. The rubber wheels 4-4 are designed in a figure-eight shape.
