Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1-Figure 7 As shown, an electric control dustproof modification device for an electric hoist overhead crane comprises a shell 1, an alignment groove 10 and a dustproof mechanism 7. A fixing plate 2 is arranged in the shell 1, and the fixing plate 2 is fixedly connected to the inner wall of the shell 1. An electric control device body 3 is fixedly connected to the fixing plate 2, and a terminal 4 is fixedly connected to the electric control device body 3. An alignment groove 10 is provided on the shell of the electric control device body 3, and a clamping hole 11 is provided at the bottom of the alignment groove 10. The alignment groove 10 is arranged around the terminal 4. The dustproof mechanism 7 comprises a mechanism shell 72, and a clamping block 74 is fixedly connected to one end surface of the mechanism shell 72, and a heat spreader 71 is fixedly connected to the other end surface of the mechanism shell 72, and a heat conduction block 75 is fixedly connected to the heat spreader 71. A wire outlet groove 76 is penetrated through the side wall of the mechanism shell 72, and the heat conduction block 75 abuts against the terminal 4. A part of the mechanism shell 72 is arranged in the alignment groove 10, and the clamping block 74 is clamped to the clamping hole 11.

[0029] The mechanism housing 72 is evenly distributed with heat sink fins 73 , which are fixedly connected to the heat spreader 71 . By connecting a number of evenly distributed heat sink fins 73 to the heat spreader 71 , the heat of the terminal 4 is easily transferred, which is more conducive to the heat dissipation of the terminal 4 .

[0030] The outer shell 1 is symmetrically provided with a mounting through slot 1 5 and a mounting through slot 2 6 , both of which penetrate the outer shell 1 . An air inlet fan 8 is sleeved and fixedly connected in the mounting through slot 1 5 , and an air exhaust fan 9 is sleeved and fixedly connected in the mounting through slot 2 6 . A heat dissipation duct is formed in the outer shell 1 through the symmetrically arranged air inlet fan 8 and the exhaust fan 9 , which is beneficial to the heat dissipation of the electric control device body 3 and the dustproof mechanism 7 .

[0031] like Figure 2 As shown, the air inlet fan 8 and the exhaust fan 9 form a heat dissipation duct from right to left in the housing 1, and the outlet slot 76 of the dustproof mechanism 7 is set upward or downward. By making the opening direction of the outlet slot 76 of the dustproof mechanism 7 perpendicular to the direction of the heat dissipation duct formed by the air inlet fan 8 and the exhaust fan 9 in the housing 1, dust is prevented from being blown toward the terminal 4.

[0032] In order to facilitate the understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in combination with specific application scenarios:

[0033] The symmetrically arranged air inlet fan 8 and the exhaust fan 9 form a heat dissipation duct in the housing 1, which is beneficial to the heat dissipation of the electric control device body 3 and the dustproof mechanism 7. By making the opening direction of the outlet slot 76 of the dustproof mechanism 7 perpendicular to the direction of the heat dissipation duct formed by the air inlet fan 8 and the exhaust fan 9 in the housing 1, dust is prevented from being blown toward the terminal 4. The contact point of the terminal 4 is hidden by the dustproof mechanism 7. After the contact point is hidden, the influence caused by excessive dust can be effectively improved, the service life is greatly improved and the failure rate during use is reduced;

[0034] The heat conductive block 75 is in contact with the terminal 4, and the heat generated at the terminal 4 is guided to the heat spreader 71 through the heat conductive block 75. The heat dissipating fins 73 are fixedly connected to the heat spreader 71. By connecting a number of evenly distributed heat dissipating fins 73 to the heat spreader 71, the heat of the terminal 4 is easily transferred, which is more conducive to the heat dissipation of the terminal 4.
