[0039] Embodiment one

[0040] As Figure 1 and Figure 2As shown, the embodiment provides a machine cover structure, which comprises a cover body 1, a mounting structure 2 and an access door 3. The cover body 1 is provided with a containing cavity 111. The cover body 1 is provided with an access opening 112 which communicates with the containing cavity 111. The mounting structure 2 is arranged in the containing cavity 111. The mounting structure 2 is used to arrange the condenser 100 in the containing cavity 111 and make the condenser 100 opposite to the access opening 112. The access door 3 comprises a first position and a second position relative to the cover body 1. In the first position, the access door 3 closes the access opening 112. In the second position, the access door 3 opens the access opening 112. When the engineering machinery equipment provided with the machine cover structure does not need to clean and maintain the condenser 100, the access door 3 closes the access opening 112. At this time, the condenser 100 is located in the containing cavity 111. The cover body 1 can avoid the condenser 100 from being affected by external sand, rain and snow and being bumped. When the condenser 100 needs to be cleaned and maintained, the entire cover body 1 does not need to be removed. Only the access door 3 needs to be switched to the second position to open the access opening 112. Since the condenser 100 is opposite to the access opening 112, the maintenance personnel can clean and maintain the condenser 100 in the containing cavity 111 through the access opening 112, which is convenient for maintenance.

[0041] Optionally, the access door 3 is hinged to the cover body 1.

[0042] Optionally, the cover body 1 comprises a cover plate 11 and a support beam. The cover plate 11 surrounds the containing cavity 111. The support beam is arranged in the containing cavity 111 and supports the cover plate 11. The mounting structure 2 is arranged on the support beam. In the embodiment, the support beam comprises a plurality of U-shaped beams 12. The plurality of U-shaped beams 12 are arranged in the containing cavity 111 surrounded by the cover plate 11 to support the cover plate 11. Since the mounting structure 2 is fixed with the condenser 100, if the mounting structure 2 is arranged on the cover plate 11, the cover plate 11 is prone to deformation. Therefore, the mounting structure 2 is arranged on the support beam.

[0043] Optionally, the access opening 112 is located on one cover wall of the cover body 1 along a first direction X. The mounting structure 2 comprises two fixing members 21. The two fixing members 21 are arranged on the cover body 1 along a second direction Y respectively. The two fixing members 21 are respectively used to be fixed with the condenser 100. The first direction X and the second direction Y are perpendicular. In the embodiment, compared with fixing one side of the condenser 100, the two fixing members 21 are respectively fixed to two sides of the condenser 100 along the second direction Y, so as to improve the stability of fixing the condenser 100. Specifically, the first direction X is along the vertical direction. In other embodiments, the first direction X can also be along the horizontal direction.

[0044] Optionally, the fixing member 21 is an angle plate 211, a first plate 2111 of the angle plate 211 is arranged on the cover body 1, and a second plate 2112 of the angle plate 211 is fixedly arranged on the condenser 100. In this embodiment, the first plate 2111 and the second plate 2112 are perpendicular to each other, the first plate 2111 is fixedly connected with the support beam, and the second plate 2112 is fixedly connected with the condenser 100. Specifically, taking the vertical direction along the first direction X as an example, the U-shaped beam 12 includes a horizontal beam 121 and two vertical beams 122 fixedly arranged at two ends of the horizontal beam 121, the first plate 2111 of each of the two fixing members 21 is fixedly connected with the two vertical beams 122 of one U-shaped beam 12, and the second plate 2112 of each of the two fixing members 21 is fixedly connected with the condenser 100.

[0045] Optionally, the fixing member 21 further includes a reinforcing rib 212 arranged in the included angle between the first plate 2111 and the second plate 2112 and fixedly connected with the first plate 2111 and the second plate 2112, respectively. In this embodiment, this arrangement can improve the connection strength of the first plate 2111 and the second plate 2112.

[0046] Optionally, the access hole 112 is located on one cover wall of the cover body 1 along the first direction X; the condenser 100 includes a suction surface 101, and the mounting structure 2 is fixedly connected with the cover body 1, so that the suction surface 101 is arranged at an included angle with the first direction X, and the suction surface 101 is used to be opposite to the access hole 112. In this embodiment, one side surface of the condenser 100 is the suction surface 101, and the fan blades are located on the suction surface 101, thereby sucking the external gas into the condenser 100 from the suction surface 101, and at the same time, the dust in the external gas accumulates on the suction surface 101, so that when the condenser 100 is cleaned and maintained, the suction surface 101 and the fan blades on the suction surface 101 are mainly cleaned and maintained, and therefore, the suction surface 101 is opposite to the access hole 112 to facilitate the maintenance and cleaning of the maintenance personnel.

[0047] Preferably, the included angle between the suction surface 101 and the first direction X is a, and the value range of a is 20°-40°. In this embodiment, since the accommodation space in the cover body 1 is limited, in order to avoid that the condenser 100 occupies too much space, the value range of a is 20°-40°, which can increase the exposed area of the suction surface 101 in the access hole 112 and avoid excessive occupation of the space in the accommodation cavity 111.

[0048] This embodiment also provides an engineering machinery device including the above-mentioned machine cover structure.
