[0010] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention, and are not used to limit the scope of the present invention. After reading the contents of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the present invention.

[0011] like Figure 1 , Figure 2 , Figure 3 As shown, a double track parallel to each other is arranged on the slow cooling ground, and at least two gantry spray vehicles are arranged on the double track. Each gantry spray vehicle includes a gantry 3, a trolley running mechanism 2 and a spray mechanism 4. The gantry 3 includes two legs 31 and a main beam 32. The distance between the two legs (i.e., the span of the gantry) is the same as the distance between the double tracks. A set of trolley running mechanisms 2 is arranged at the bottom of the two legs 31. The two sets of trolley running mechanisms 2 drive the gantry 3 to move along the double track. The spray mechanism 4 includes a self-priming pump 41, a water supply pipeline 42, a main pipeline 43, a branch pipeline 44, a spray pipeline 46, and a spray nozzle 47. The self-priming pump 41 is installed on any leg 31 of the gantry. The water inlet of the self-priming pump 41 is connected to the ground sewer 45 through the water supply pipeline 42. The water outlet of the self-priming pump 41 is connected to two branch pipelines 44 through the main pipeline 43. The branch pipelines 44 are fixed on the main beam 32 of the gantry. Each branch pipeline 44 is downward. At least one spray pipeline 46 is extended, and an electric ball valve is arranged on each spray pipeline 46. A spray nozzle 47 is arranged at the end of the spray pipeline 46. A water pressure sensor is installed on the main pipeline 43. The water pressure sensor, electric ball valve, self-priming pump 41 and trolley running mechanism 2 of each gantry spray vehicle are connected to the controller; each gantry spray vehicle also includes an anti-torsion correction mechanism and an anti-collision mechanism. The anti-torsion correction mechanism includes an absolute value encoder, a calibration switch and an electromagnetic induction block. An absolute value encoder and a calibration switch are arranged on the passive wheels of the two groups of trolley running mechanisms 2 of each gantry spray vehicle, and a plurality of electromagnetic induction blocks cooperating with the calibration switch are arranged on each track; the anti-collision mechanism includes a laser rangefinder arranged at both ends of the trolley ground beam of each gantry spray vehicle, and two laser rangefinders are respectively arranged on both sides of the trolley ground beam, and the absolute value encoder, the calibration switch and the laser rangefinder are all connected to the controller.

[0012] The absolute value encoder, the calibration switch, the electromagnetic induction block and the laser rangefinder all have common components in the prior art.

[0013] Six or eight gantry spray vehicles are arranged on the double tracks on the slow cooling ground at the same time, and the number of gantry spray vehicles can be adjusted arbitrarily according to the size of the slow cooling ground or the amount of slag that needs to be sprayed for slow cooling.

[0014] The utility model effectively combines the mobile gantry with the spray cooling system, realizes the efficient slow cooling of the slag, and solves the problems of the fixed spray slag slow cooling system, such as large investment, long pipeline, poor spray effect at the end of the pipeline, etc., which leads to poor slow cooling effect of the slag. The utility model can perform slow cooling operation on a large number of slag bags 5 at one time, and the slow cooling efficiency of the slag bags is high.

[0015] By setting an absolute value encoder and a calibration switch on the passive wheels of the two sets of trolley running mechanisms of each gantry spray car, and setting multiple electromagnetic induction blocks cooperating with the calibration switches on each track, accurate positioning and anti-torsion correction of each gantry spray car can be achieved; by setting a laser rangefinder at both ends of the trolley ground beam of each gantry spray car, and two laser rangefinders are respectively set on both sides of the trolley ground beam, it is effectively prevented that the gantry spray car collides with other gantry spray cars on the same track when moving, and the intelligent operation control of the slow cooling field is realized.

[0016] The gantry 3 and the trolley running mechanism 2 constitute the movable frame of the gantry sprayer, and the spray mechanism performs effective spraying. The spray mechanism consists of a self-priming pump 41, a water supply pipeline 42, a main pipeline 43, a branch pipeline 44, an electric ball valve, a spray pipeline 46, a spray nozzle 47, etc. Each gantry sprayer is equipped with a self-priming pump 41, which is responsible for the water supply of the spray nozzle 47. The self-priming pump 41 is installed on the leg of the gantry and penetrates into the ground sewer 45 through the water supply pipeline 42. The self-priming pump 41 is controlled by a controller. The self-priming pump 41 pumps water through a main pipeline 43 into two branch pipelines 44 on the upper part of the gantry, and then flows through the branch pipeline 44 to multiple spray pipelines 46, and finally sprays through the spray nozzle 47 set at the end of the spray pipeline 46. A water pressure sensor is installed on the main pipeline 43, and the water pressure sensor is connected to the controller, which can monitor the water pressure changes of the spray mechanism in real time so as to make timely adjustments. An electric ball valve is provided on each spray pipeline 46, so that part of the spray nozzles 47 can be closed in time according to the change of water pressure or other working conditions.

[0017] The spray mechanism can be operated in two control modes: local and remote. In the local state, the opening and closing of the self-priming pump and the opening and closing of the electric ball valve can be controlled separately on site; in the remote state, the self-priming pump and the electric ball valve are controlled by receiving signals from the host computer. Water pressure detection, operation signals and comprehensive faults are fed back to the host computer, and PROFINET communication is carried out with the host computer.

[0018] The precise positioning and anti-torsion correction mechanism of each gantry spray truck is realized by controller + absolute value encoder + calibration switch + electromagnetic induction block. Operation monitoring and speed following are realized, and finally the displacement of the left and right legs is the same, ensuring that the main beam does not undergo torsional deformation, and ensuring that the left and right sides of the gantry spray truck can move forward synchronously without large angle deviation. When the deviation of the two legs of the trolley is greater than 1‰ and the span of the trolley is less than 2‰, the anti-torsion correction mechanism performs automatic oblique correction; when the deviation of the two legs of the trolley is greater than 2‰ and the span of the trolley is less than 3‰, the anti-torsion correction mechanism performs slow automatic oblique correction and issues an audible and visual alarm; when the deviation of the two legs of the trolley is greater than 3‰ of the span of the trolley, the trolley stops automatically and can only be corrected manually, and an audible and visual alarm is issued. The use of controller + absolute value encoder + calibration switch + electromagnetic induction block for precise positioning and anti-torsion correction can be referred to the prior art CN111776945A.

[0019] A laser rangefinder is installed at both ends of the trolley beam of each gantry spray truck, and two laser rangefinders are installed on both sides of the trolley beam to detect the distance in two directions. The laser rangefinder emits a laser beam forward, which is reflected by the end of the trolley beam of the gantry spray truck in front, and the distance between the two gantry spray trucks is obtained. Before or during the movement of a gantry spray truck, the laser rangefinder installed at its end needs to measure the distance between it and the gantry spray truck in front of it in the moving direction. If it is greater than the set distance, it can move, and if it is less than the set distance, it cannot move or stops moving. The anti-collision mechanism makes the spray truck safe and will not cause accidents even in the event of misoperation or failure.

[0020] The above is only a preferred embodiment of the present invention. It should be pointed out that, for those skilled in the art, several changes and improvements can be made without departing from the overall concept of the present invention, and these should also be regarded as the protection scope of the present invention.
