[0030] The utility model is further introduced below in conjunction with the accompanying drawings and specific embodiments:

[0031] refer to Figures 1 to 5 A monorail crane exhaust gas drainage device is used for a monorail crane driven by a diesel engine (or a gasoline engine or a conventional fuel engine at present). The monorail crane exhaust gas drainage device includes: an exhaust gas control box 2 and a drainage pipe 1.

[0032] The exhaust gas control box 2 has an air inlet end and at least two air outlet ends. The air inlet end of the exhaust gas control box 2 is configured to match the exhaust gas exhaust end of the monorail crane locomotive used. The number of drainage pipes 1 matches the number of air outlet ends of the exhaust gas control box 2. A mesh hole is opened on the side of the drainage pipe 1, and one end of the drainage pipe 1 is fixedly installed on the air outlet end of the exhaust gas control box 2.

[0033] When in use, the air inlet end of the exhaust gas control box 2 is fixedly installed at the exhaust gas outlet of the monorail crane. The exhaust gas generated by the locomotive of the monorail crane enters the exhaust gas control box 2, and then disperses into the drainage pipe 1, and finally disperses and discharges from the mesh holes on the side of the drainage pipe 1, thereby avoiding the exhaust gas from being concentrated in one direction and causing excessive carbon monoxide in local areas, causing accidents such as dangerous alarms in the tunnel, and ensuring the safety of unloading workers.

[0034] In one embodiment, the exhaust gas control box 2 includes: a connecting base 201, the connecting base 201 is a shell structure, and the connecting base 201 has a group of through channels, and the through channels form two gas outlets on the side of the connecting base 201.

[0035] The number of the drainage tubes 1 can be designed to be two, which are distributed on both sides of the through channel connecting the base 201 , and the drainage tubes 1 are fixedly installed on both sides of the through channel connecting the base 201 by welding.

[0036] A hole 205 is provided on the side of the connecting base 201 , and the hole 205 matches the tail gas outlet of the monorail suspension. A plurality of partition plates 206 which are distributed in parallel and at intervals are fixedly installed on the inner side of the hole 205 .

[0037] The hot exhaust gas discharged from the exhaust gas outlet of the monorail crane passes through the hole 205, that is, through the gap between a number of parallel and spaced partition plates 206 (generally, before the exhaust gas outlet of the monorail crane, the exhaust gas needs to pass through the cooling water tank on the monorail crane). The water vapor contained in the exhaust gas of the monorail crane is cooled and liquefied when it contacts the partition plate 206.

[0038] A liquid release hole 202 is provided on the side of the connecting base 201. The steam water generated by the above-mentioned liquefaction accumulates inside the connecting base 201 and is discharged from the liquid release hole 202 (it is worth noting that after the exhaust gas control box 2 is installed on the locomotive of the monorail crane, the liquid release hole 202 is located at the bottom of the connecting base 201).

[0039] In one embodiment, a mounting plate 204 is fixedly connected to a side surface of the connection base 201 , and a mounting hole 203 is formed on a side surface of the mounting plate 204 .

[0040] In one embodiment, the drainage tube 1 includes: a square tube body 101 , and mesh holes are formed on the side of the square tube body 101 .

[0041] The connecting base 201 of the exhaust gas control box 2 can be designed as a rectangular shell, and the first end of the square tube body 101 is fixedly connected to the outlet end of the exhaust gas control box 2, that is, the first end of the square tube body 101 is inserted into the inner side of the connecting base 201 of the exhaust gas control box 2, and then sealed by full welding. The second end of the square tube body 101 is fixedly connected to the circular tube 104, and the length of the circular tube 104 located on the inner side of the square tube body 101 is 1 / 3-1 / 2 of the length of the square tube body 101.

[0042] like Figure 5 The arrow in the figure indicates the direction of exhaust gas flow inside the drainage pipe 1. The exhaust gas can be discharged from the mesh holes on the side of the square tube body 101, or from the circular tube 104. The design of this structure can better maintain uniform exhaust of the exhaust gas, especially the outer end of the circular tube 104, which can be designed at a farther position to avoid affecting the on-site unloading personnel.

[0043] In one embodiment, the cross-section of the square tube body 101 is square, so that it has four faces. The four faces of the square tube body 101 are parallel to each other, forming a first group of parallel side faces and a second group of parallel side faces. Fully distributed mesh holes 102 are opened on the first group of parallel side faces of the square tube body 101, and semi-distributed mesh holes 103 are opened on the second group of parallel side faces of the square tube body 101.

[0044] In one embodiment, the drainage pipe 1 and the exhaust gas control box 2 are both made of stainless steel, and other corrosion-resistant metals and alloy materials may also be used.

[0045] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementations, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
