It should be understood that the following text is only used to describe one or several specific embodiments of the utility model, and does not strictly limit the protection scope of the utility model specifically requested.
[0027] As Figures 1-4 shown, a dustproof chain storage device for electric hoist of a travelling crane, comprising a rack 1, the bottom of the rack 1 is fixedly installed with a main body 2, the surface of the main body 2 is wound with a chain body 3, one end of the chain body 3 is fixedly connected with a lifting hook 4;
[0028] One side of the rack 1 is fixedly installed with a retracting mechanism 5, the top of the lifting hook 4 is provided with an anti-collision mechanism 6, the inside of the retracting mechanism 5 is provided with a cleaning mechanism 7.
[0029] Among them, the retracting mechanism 5 includes a connecting rod 51 and a square groove 53, the bottom of the connecting rod 51 is fixedly connected with a tray 52, the bottom of the tray 52 is fixedly connected with the square groove 53, one side of the square groove 53 is provided with a circular pipe 54.
[0030] Referring to the accompanying Figure 1 and Figure 2 , in the embodiment, the main body 2 is used to drive the chain body 3 to drive the lifting hook 4 to move vertically, and the lifting hook 4 is used to drive the anti-collision mechanism 6 to move vertically synchronously.
[0031] In the above embodiment, the main body 2 has a driving motor, and the driving motor can make the main body 2 work, so that the chain body 3 realizes retracting, so that the lifting hook 4 moves vertically, and when the lifting hook 4 rises, the anti-collision mechanism 6 can buffer the impact between the lifting hook 4 and the retracting mechanism 5, thereby improving the safety.
[0032] Further, since the tray 52 is fixedly installed with the rack 1 through the connecting rod 51, the shaking of the rack 1 can also be reduced under the action of the anti-collision mechanism 6, thereby improving the stability of the equipment, and meanwhile, the bottom of the tray 52 is provided with a circular pipeline 54, wherein the bottom of the circular pipeline 54 is in the shape of a trumpet, and the chain body 3 penetrates through the circular pipeline 54 to drive the lifting hook 4 to move, and meanwhile, the bottom of the chain body 3 is vertically rotated in the inside of the square groove body 53, so that the square groove body 53 collects the pollutants, thereby avoiding the pollution from falling.
[0033] With reference to the accompanying drawings Figure 1 and Figure 3 In the embodiment, the anti-collision mechanism 6 comprises a rubber seat 61 and a spring 62, and the rubber seat 61 abuts against the mounting plate 63 through the spring 62.
[0034] In the above embodiment, since the rubber seat 61 and the spring 62 are sleeved on the outside of the chain body 3, and the cross-shaped through slot is formed in the inside of the rubber seat 61, the rubber seat 61 can slide on the surface of the chain body 3, and the rubber seat 61 can be connected with the lifting hook 4 through the cooperation of the spring 62 and the mounting plate 63.
[0035] Further, since the rubber seat 61 is arranged, when the lifting hook 4 moves upward, the rubber seat 61 first contacts the circular pipeline 54 to provide primary buffering, and then the secondary buffering is provided through the cooperation of the rubber seat 61 and the spring 62, so that when the lifting hook 4 rises too fast, the impact on the retracting mechanism 5 and the rack 1 is reduced.
[0036] With reference to the accompanying drawings Figure 2 and Figure 4 In the embodiment, the cleaning mechanism 7 comprises a roller brush 71, the roller brush 71 is hingedly connected in the inside of the square groove body 53 through a linkage rod 72, one side of the linkage rod 72 is hingedly connected with an elastic telescopic rod 74 through a hinge seat 73, and a fixed column 75 is rotationally installed at the bottom of the elastic telescopic rod 74.
[0037] In the above embodiment, two groups of roller brushes 71 are hingedly connected with the square groove body 53 through the linkage rod 72, so that the roller brushes 71 can move in the inside of the square groove body 53, and a rotating shaft is installed in the inside of the linkage rod 72 and is fixedly connected with the roller brush 71, so that the roller brush 71 can rotate in the inside of the square groove body 53.
[0038] Specifically, since the linkage rod 72 is rotationally installed in the inside of the square groove body 53, the roller brush 71 moves in the square groove body 53, and the elastic telescopic rod 74 can rotate with the square groove body 53 through the fixed column 75, so that the elastic telescopic rod 74 drives the roller brush 71 to swing in the inside of the square groove body 53 under the elastic telescopic action of the fixed column 75.
[0039] More specifically, since the elastic telescopic rod 74 can drive the linkage rod 72 to move downwards through the hinged seat 73, and the linkage rod 72 can drive the roller brush 71 to abut against the chain body 3, then under the rotating action of the roller brush 71, the black contaminants on the chain body 3 can be left in the square groove 53, so as to avoid being taken out and falling on the glass cloth.
[0040] The working principle of the utility model is as follows: the tray 52 of the retractable mechanism 5 is installed below the rack 1 by using bolts, the square groove 53 installed below the tray 52 can accommodate the chain body 3, and the other end of the chain body 3 can pass through the circular pipeline 54 to install the lifting hook 4; when the main body 2 is used, the lifting hook 4 can be driven to move vertically; during the movement of the lifting hook 4, the other end of the chain body 3 moves to the inside of the square groove 53; during the movement, under the action of the roller brush 71 and the elastic telescopic rod 74, the roller brush 71 scrapes the black contaminants on the chain body 3, so as to avoid the chain body 3 from falling on the glass cloth with the contaminants; during the lifting of the lifting hook 4, the rubber seat 61 and the spring 62 provide two times of buffering through the arrangement of the anti-collision mechanism 6, so as to reduce the collision to the retractable mechanism 5 and the rack 1, and then improve the stability of the device.
[0041] The above is only the preferred embodiment of the utility model, and it should be pointed out that for ordinary skilled persons in the technical field, several improvements and refinements can be made without departing from the principle of the utility model, and these improvements and refinements should also be regarded as the protection range of the utility model. The structures, devices and operation methods not specifically described and explained in the utility model are implemented according to the conventional means in the field, unless otherwise specified and limited.
