DETAILED DESCRIPTION

[0030] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation methods, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0031] See also Figure 1-3The present embodiment provides a device for steel bridge deck construction, comprising a hollow mobile shell 1, a scratching assembly 2 and a collecting assembly 3. The mobile shell 1 can be movably arranged on the steel bridge deck, and the scratching assembly 2 is arranged in the mobile shell 1 for scratching the steel bridge deck; the collecting assembly 3 is arranged in the mobile shell 1, and along the moving direction of the mobile shell 1, the collecting assembly 3 is located behind the scratching assembly 2; the collecting assembly 3 comprises a collecting air pump 301 and a hollow collecting box 302, the collecting box 302 is arranged on the side wall of the mobile shell 1, the collecting air pump 301 is connected to the collecting box 302, and a collecting groove 101 is provided on the side wall of the mobile shell 1, one end of the collecting groove 101 is interconnected with the collecting box 302, and the other end thereof is located on the surface of the steel bridge deck, and the collecting assembly 3 is used to collect salt spray particles on the steel bridge deck; the present scheme is provided with Collecting component 3, after the scratching component 2 scratches the steel bridge deck, the temperature of the scratched area will increase, and the content of salt mist in the air at sea is relatively high, which makes the salt mist particles in the air easily adhere to the scratched area, and the collecting component 3 absorbs and collects the salt mist particles in the scratched area through the force of air pressure, so as to prevent the chloride ions in the salt mist particles from chemically reacting with the steel bridge deck due to high temperature and corroding the steel bridge deck, thereby solving the problem that for steel bridge decks built at sea, there is salt mist at sea, which contains a large amount of chloride ions. When the steel bridge deck is scratched by construction machinery, the scratched part of the steel bridge deck will generate high temperature, and this part of the area is easy to react chemically with the chloride ions in the salt mist, resulting in the scratched part of the steel bridge deck being corroded by the salt mist, thereby affecting the service life of the steel bridge.

[0032] Specifically, the scratching assembly 2 of the present scheme includes a driving motor 201, a lifting hydraulic cylinder 202, a driving shaft 203 and a plurality of scratching disks 204. The lifting hydraulic cylinder 202 is vertically arranged in the movable shell 1, the driving motor 201 is connected to the output end of the lifting hydraulic cylinder 202, the output end axis of the driving motor 201 and the output end axis of the lifting hydraulic cylinder 202 are arranged perpendicular to each other, the driving shaft 203 is coaxially connected to the output end of the driving motor 201, and a plurality of scratching disks 204 are arranged at equal intervals along the central axis direction of the driving shaft 203; it should be noted that the role of the lifting hydraulic cylinder 202 of the present scheme is to control the height of the scratching disk 204, and the role of the driving motor 201 is to control the rotation of the driving shaft 203, thereby controlling the rotation of the scratching disk 204 arranged on the driving shaft 203, so as to scratch the surface of the steel bridge plate.

[0033] It should also be noted that the cross-sectional width of the scratch disk 204 of the present embodiment increases gradually from the direction close to its central axis. Such a setting can cause scratching of a larger area on the surface of the steel bridge deck while scratching the steel bridge deck at the same depth as much as possible.

[0034] In addition, it should be noted that since the collection groove 101 of the present solution is used to collect salt spray particles in the scratches caused by the scratch disk 204 on the steel bridge plate, based on this, the collection groove 101 of the present solution is provided with a plurality of collection grooves 101, and the plurality of collection grooves 101 are arranged in the side wall of the movable shell 1 at equal intervals along the central axis direction of the driving shaft 203, and the plurality of collection grooves 101 are matched one-to-one with the plurality of scratch disks 204, and any collection groove 101 is located behind the corresponding scratch disk 204.

[0035] Furthermore, the scratching component 2 of the present solution will generate iron filings when scratching the steel bridge plate, and the heat generated during the operation of the device will basically be transferred to the surface of the iron filings and the scratched area. Therefore, in order to prevent the salt mist in the air from adhering to the iron filings, it is necessary to clean the iron filings generated during the operation of the scratching component 2; based on this, the present solution is also provided with a cleaning component 4, which includes a cleaning rod 401, a cleaning plate 402, a cleaning spring 403 and a cleaning block 404. The cleaning plate 402 is horizontally connected to the output end of the lifting hydraulic cylinder 202, and the cleaning plate 402 is provided with a sliding hole. The cleaning rod 401 is vertically slidably arranged in the sliding hole. The two ends of the cleaning spring 403 are respectively connected to the top of the cleaning rod 401 and the cleaning plate 402, and the cleaning block 404 is arranged at the bottom of the cleaning rod 401. end; the cleaning block 404 is located between the scratch disk 204 and the collecting tank 101; when the output end of the lifting hydraulic cylinder 202 extends toward the direction of the steel bridge plate, not only the scratch disk 204 scratches the steel bridge plate, but also the cleaning block 404 and the surface of the steel bridge plate are fitted together. Since the cleaning block 404 is arranged between the scratch disk 204 and the collecting tank 101 along the moving direction of the movable shell 1, the cleaning block 404 can process the iron filings adhered to the scratch area generated by the scratch disk 204 during operation, so that the iron filings cannot be connected to the steel bridge plate, and are then absorbed and collected by the collecting tank 101, thereby completing the cleaning of the iron filings.

[0036] Furthermore, the above embodiment only cleans the iron filings in the scratch area. In fact, the surface of the scratch groove generated after the scratching component 2 scratches the steel bridge plate will generate high temperature, which can also chemically react with the salt mist in the air to corrode the surface of the scratch groove. Therefore, in addition to the effect of cleaning iron filings, the cleaning component 4 of this scheme also needs to cool the scratch groove. Based on this, the cleaning component 4 of this scheme also includes a cooling block 405. Several cooling blocks 405 are arranged at equal intervals at the bottom of the cleaning block 404 along the central axis of the drive shaft 203. Several cooling blocks 405 are matched with several scratch disks 204 in a one-to-one manner. After any cooling block 405 is located at the corresponding scratch disk 204, the shape of the cooling block 405 is the same as the shape of the scratch groove opened on the steel bridge plate by the scratch disk 204. Such a setting enables the cooling block 405 arranged at the bottom of the cleaning block 404 to fit with the scratch groove when the cleaning block 404 moves into the scratch area to achieve cooling treatment.

[0037] In order to further improve the cooling effect of the cooling block 405 on the corresponding scratch groove, the cleaning component 4 of the present scheme also includes a water tank 406 filled with water and a water pump 407. The water tank 406 is arranged on the side wall of the movable shell 1, and the water pump 407 is connected to the water tank 406. The interior of the cooling block 405 is hollow, and the cleaning block 404 is provided with a cooling input groove and a cooling output groove. The two ends of the cooling input groove are respectively connected to one end of the interior of a plurality of cooling blocks 405 and one end of the water tank 406, and the two ends of the cooling output groove are respectively connected to the other end of the interior of a plurality of cooling blocks 405 and the other end of the water tank 406. With such a setting, through the operation of the water pump 407, the water flow in the water tank 406 flows through each cooling block 405 through the cooling input groove, and then the water in each cooling block 405 flows back to the water tank 406 through the cooling output groove. The heat of the cooling block 405 is taken away by the flow of water, thereby achieving the cooling effect of the cooling block 405 on the scratch groove.

[0038] In order to ensure that the water in the water tank 406 flows along a predetermined path, the cleaning component 4 of the present scheme also includes two one-way valves, which are respectively arranged at the two ends of the water tank 406 and the cleaning block 404 that are interconnected. By providing a one-way valve, the one-way valve arranged in the cooling input groove ensures that water flows from the water tank 406 to the cooling block 405, while the one-way valve arranged in the cooling output groove ensures that water flows from the cooling block 405 to the water tank 406.

[0039] In addition, it is worth mentioning that the cleaning component 4 of the present scheme also includes a cleaning module 409, a connecting block 410, a hinge rod 411 and a hinge spring 408. The connecting block 410 is arranged at the top end of the cleaning rod 401, and the middle end of the hinge rod 411 is hingedly arranged with the movable shell 1. Such an arrangement enables the hinge rod 411 to rotate along its hinge point. The two ends of the hinge spring 408 are respectively connected to the movable shell 1 and one end of the hinge rod 411. One end of the hinge rod 411 is located at the bottom of the cleaning plate 402. The cleaning module 409 is arranged on the other end of the hinge rod 411. The cleaning module 409 is located at the bottom of the connecting block 410. The cleaning module 409 is communicatively connected with the water pump 407. The hinge rod 411 can lock or release its horizontal setting state. The cleaning module 409 can lock or release its press-fit relationship with the connecting block 410. Through such an arrangement, when the lifting hydraulic rod begins to extend When the cleaning plate 402 is moved out, the cleaning plate 402 will be controlled to move in the direction of the steel bridge plate. After the cleaning plate 402 reaches the specified position, the cleaning plate 402 will press one end of the hinged rod 411, so that the originally horizontally set hinged rod 411 is transformed into an inclined state, and one end of the hinged rod 411 with the cleaning module 409 will be lifted. At this time, the cooling block 405 is in a state of being fitted with the surface of the steel bridge plate, but the cleaning block 404 has not yet been fitted with the steel bridge plate; when the movable shell 1 moves, the scratching disk 204 scratches a scratching groove due to rotation, and after the cooling block 405 is fitted with the scratching groove, the cleaning block 404 will overcome the action of the cleaning spring 403 and be fitted with the surface of the steel bridge plate, and the connecting block 410 connected to the cleaning block 404 will also descend together with the cleaning block 404. At this time, the connecting block 410 will press the cleaning module 409, so that the cleaning module 409 drives the water pump 407 to work. After the device completes its work, the output end of the lifting hydraulic rod contracts, thereby resetting the entire device and the water pump 407 stops working.

[0041] S1: The moving shell 1 starts to slide along the steel bridge deck;

[0042] S2: Scratching component 2 starts working and performs scratching on the steel bridge plate;

[0043] S3: The collecting component 3 also starts to work, collecting the salt spray particles in the scratched area on the steel bridge plate.
