[0019] The following will combine with the drawings to describe in detail specific embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the description of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0020] Such as Figures 1 to 2As shown in the figure, an embodiment of one aspect of the present application provides a spark extinguishing device for a crane, including a spark extinguisher 1 for extinguishing sparks in the crane exhaust gas, a selective catalytic reduction (hereinafter referred to as SCR) assembly 8 for purifying the crane exhaust gas, and an exhaust pipe assembly connected between the spark extinguisher 1 and the SCR assembly 8; the exhaust pipe assembly includes an exhaust pipe 6, a buckle 2 provided at one end of the exhaust pipe 6, and a first hoop 7 provided at the other end of the exhaust pipe 6. The spark extinguisher 1 is connected to the exhaust pipe 6 through the buckle 2, and the SCR assembly 8 is connected to the exhaust pipe 6 through the first hoop 7.

[0021] The exhaust pipe 6 includes a first pipe section and a second pipe section connected in a bent manner. The first pipe section 6A and the second pipe section 6B are bent to form an angle of 85°-95°. The length of the first pipe section 6A is greater than the length of the second pipe section 6B. The buckle 2 is provided at the end of the first pipe section 6A, and the first hoop 7 is provided at the end of the second pipe section 6B. The first pipe section 6A includes a bendable exhaust pipe joint section 6A1, and the buckle 2 is provided at the end of the exhaust pipe joint section 6A1.

[0022] The buckle 2 is used to connect the spark extinguisher 1 to the exhaust pipe joint section 6A1. The inner diameter of the buckle 2 is adjustable, and an appropriate buckle 2 can be selected according to the size of the spark extinguisher 1, so as to ensure the stability of the spark extinguishing device. At the same time, there is no need to open holes on the spark extinguisher 1, which extends its service life and reduces the replacement cost.

[0023] The exhaust pipe joint section 6A1, as a transition pipe section connecting the spark extinguisher 1 and the exhaust pipe 6, has good adaptability. At the same time, in order to adjust the angle of the spark extinguisher 1 to make the spark extinguisher 1 better adapt to the crane operation environment, the exhaust pipe joint section 6A1 is bendable, and its bendable angle range is 90°-180°. The best angle can be judged according to the actual use environment. The bending angle of this embodiment is preferably 180°.

[0024] The exhaust pipe assembly further includes a second hoop 4. The second hoop 4 is sleeved on the end of the exhaust pipe joint section 6A1 away from the buckle 2. When the second hoop 4 is locked, it has good reliability, which can prevent air leakage and dust of the exhaust pipe 6. At the same time, the second hoop 4 can select a corresponding hoop according to the sizes of the exhaust pipe 6 and the exhaust pipe joint section 6A1, and has replaceability.

[0025] The exhaust pipe assembly further includes an exhaust pipe fixing bracket 5, which is fixedly connected to the outer surface of the exhaust pipe 6 in the area between the first hoop 7 and the second hoop 4; the exhaust pipe fixing bracket 5 is provided with mounting holes for fixing, wherein the first mounting hole is used to determine the mounting position of the exhaust pipe fixing bracket 5 on the exhaust pipe 6, and the second mounting hole is used to determine the mounting position of the exhaust pipe fixing bracket 5 on the fixing surface.

[0026] The first hoop 7 is arranged at the other end of the exhaust pipe 6, and the SCR assembly 8 is connected to the exhaust pipe 6 through the first hoop 7; the first hoop 7 can adjust the hoop tightness according to the specific shape of the exhaust pipe 6, so that the first hoop 7 precisely adapts to the specific shape of the exhaust pipe 6 and then is fixedly connected to improve the reliability of the device.

[0027] In summary, in a spark extinguishing device provided by the above-mentioned embodiment of the present invention, a buckle 2 with adjustability is used to connect the spark extinguisher 1 to the exhaust pipe joint section 6A1. The buckle 2 can select a suitable buckle 2 according to the size of the spark extinguisher 1, improving the installation and stability of the whole device; when the second hoop 4 is locked, it has good reliability, and the second hoop 4 can select a corresponding hoop according to the sizes of the exhaust pipe 6 and the exhaust pipe joint section 6A1, having high replaceability and saving costs. In addition, the bendable exhaust pipe joint section 6A1 is for the spark extinguisher 1 to better adapt to the crane operation environment, and the bend angle can be selected from 90° to 180°; the first hoop 7 can also adjust its tightness according to the specific shape of the exhaust pipe 6 to make the two precisely match, thereby improving the reliability of the device.

[0028] Another embodiment of the present invention provides a crane, which includes the above-mentioned spark extinguishing device and an exhaust system. The spark extinguishing device is installed at the end of the exhaust system of the crane for extinguishing the sparks in the tail gas generated by the exhaust system; wherein, the exhaust pipe 6 of the spark extinguishing device is communicated with the exhaust system, and the SCR assembly 8 is arranged at the connection between the exhaust system and the exhaust pipe 6. When the crane operates, the exhaust system discharges untreated tail gas with sparks. The untreated tail gas first reaches the SCR assembly 8, and the relatively high-content nitrogen oxides in the catalytic converter of the SCR assembly 8 finally generate harmless nitrogen and water through catalytic reduction reaction; the tail gas treated by the SCR assembly 8 then reaches the spark extinguisher 1 through the exhaust pipe assembly to extinguish the sparks in the tail gas, and finally discharges the spark-free tail gas, thereby ensuring the safety and stability of the crane operation.

[0029] The above is only the specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
