DETAILED DESCRIPTION

[0017] The explosion-proof bridge crane with a fire-fighting device of the utility model is described in more detail below with reference to the accompanying drawings and through specific implementation methods.

[0018] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0019] See also Figure 1-4 The present embodiment is an explosion-proof bridge crane with a fire-fighting device. The crane is provided with a retractable top plate on the top of the trolley, which not only plays a role in sun protection and rain protection, but also does not affect the maintenance of the trolley. A water tank is provided at the bottom of the trolley, and an automatic fire extinguishing component is provided in the electrical box, which further improves the safety of the crane during operation. The crane mainly comprises a main beam 1 and a trolley 2. The trolley 2 runs on the track of the main beam 1, and the trolley 2 is provided with a ceiling and a sprinkler mechanism.

[0020] In this embodiment, see Figure 2-3 The top includes a support plate 31, a top plate 37 and a limiting unit. The top plate 37 includes a main shaft 38 and a folding blade 39. The folding blade 39 is installed on both sides of the main shaft 38 to form a V-shaped groove. A counterweight block is arranged at the lower part of the main shaft 38 to facilitate the top plate 37 to maintain balance in a natural state. The side height of the left folding blade is lower than the height of the right folding blade, which is convenient for the two adjacent folding blades to match each other. A transverse sliding groove is opened on the upper part of the support plate 31, and the end of the main shaft 38 of the top plate 37 is arranged in the sliding groove, which can drive the top plate to slide freely along the sliding groove. The limiting unit includes a side plate 32, a limiting plate 33 and a spring 35. The upper part of the limiting plate 33 is evenly provided with limiting grooves 34 corresponding to the main shaft 38 of the top plate 37. The side plate 32 is fixed to the outer side of the support plate 31, the limiting plate 33 is arranged in the vertical groove formed by the side plate 32 and the support plate 31, and the spring 35 is installed in the vertical groove at the bottom of the limiting plate 33.

[0021] In this embodiment, see Figure 4The spray mechanism includes a water tank 41 and a nozzle 45. The water tank 41 is provided with evenly arranged partitions along the travel direction of the trolley 2. The bottom of the partition does not contact the bottom plate of the water tank 41 to avoid the water hammer effect on the movement of the trolley. The nozzle 45 is installed in front of the running wheel of the trolley 2. The water tank 41 is installed at the bottom of the trolley 2 and does not affect the layout of the various components on the trolley. A detachable water inlet pipe 42 is installed on the top of the water tank 41 to facilitate water replenishment of the water tank. The nozzle 45 is connected to the water pump installed at the bottom of the water tank 41 through a water pipe 44. An automatic fire extinguishing component is arranged in the electrical box of the trolley 2. The automatic fire extinguishing component includes an automatic fire extinguisher and a temperature sensor. The automatic fire extinguisher and the temperature sensor are both arranged in the electrical box.

[0022] When the roof of the trolley is unfolded, it can provide shade and shelter from rain. The V-shaped groove formed on the top plate allows rainwater to flow away easily. When the wind is strong, the top plate can rotate with the wind in the limit groove to resolve the impact of wind on the trolley. When the trolley needs to be maintained, press the limit plate downward to release the restriction of the top plate, and the top plate can be gathered on one side along the slide groove to facilitate the maintenance of the trolley.

[0023] When the trolley is moving, sparks are likely to occur due to friction between metals when it slips, which is especially dangerous in high temperatures in summer. In this case, a sprinkler is used to spray water between the traveling wheels and the track to reduce the occurrence of sparks. At the same time, a temperature sensor is used to monitor the temperature changes of components in the electrical box at all times. When the temperature exceeds the set danger value, an automatic fire extinguisher is used to take timely measures to improve the safety performance of the crane during operation.
