Detailed Implementation

[0022] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, these embodiments do not limit the scope of protection of the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.

[0023] This utility model discloses a cooling and drying device for wear-resistant steel castings, see reference. Figures 1-3 As shown, the device includes a housing 12 and a pair of guide rails 1. Guide wheels 3 are installed at the four corners of the housing 12 and travel on the guide rails 1. Through slots 13 are provided on both sides of the housing 12. Wear-resistant steel castings are placed between the pair of guide rails 1 via a pallet. The housing 12 can be pushed by the operator to travel along the guide rails 1 and allow different wear-resistant steel castings to enter the housing 12. The through slots 13 are provided for the entry and exit of wear-resistant steel castings.

[0024] A support box 10 is fixedly installed on the upper side of the housing 12, and an electric lifting platform 8 is fixedly installed on the upper side of the support box 10. A pair of baffles 14 are fixedly installed on the upper side of the electric lifting platform 8 via a support rod 6. The baffles 14 are connected to the through groove 13. The electric lifting platform 8 is an existing device. After extension and retraction, the baffles 14 can be moved up and down via the support rod 6, thereby realizing the action of opening or closing the through groove 13.

[0025] A bent pipe 4 is rotatably installed in the middle of the inside of the housing 12. The bent pipe 4 is Z-shaped. Nozzles 2 are evenly connected to the side of the bent pipe 4 away from the housing 12. A drive assembly 7 for rotating the bent pipe 4 and an air supply assembly 9 for inputting high-pressure gas into the bent pipe 4 are provided on the upper side of the housing 12. The high-pressure gas supplied into the bent pipe 4 by the air supply assembly 9 is output through the nozzles 2. At the same time, the drive assembly 7 rotates the bent pipe 4 in a circular motion, thereby drying the water on the wear-resistant steel casting.

[0026] like Figure 3 As shown, the drive assembly 7 includes a geared motor 71 and a driven gear 73. The geared motor 71 is fixedly installed on the upper side of the housing 12. The output end of the geared motor 71 passes downward through the housing 12 and is fixedly installed with a drive gear 72. The driven gear 73 is fixedly installed on the bent pipe 4. The driven gear 73 meshes with the drive gear 72. When the geared motor 71 is working, it can rotate the drive gear 72, and the meshed driven gear 73 can rotate the bent pipe 4.

[0027] The diameter of the driving gear 72 is smaller than that of the driven gear 73, which plays a role of reducing speed and increasing torque, and reduces the working load of the speed reducer 71.

[0028] The upper side of the box body 12 is fixedly provided with a support cylinder, which is rotatably assembled with the elbow pipe 4 through a bearing; the support cylinder is used to increase the rotation support area of the elbow pipe 4, thereby improving the stability of the rotation of the elbow pipe 4.

[0029] The upper side of the box body 12 is fixedly provided with a circular slide rail 5, and the slide table of the circular slide rail 5 is fixedly assembled with the elbow pipe 4 through a support rod; the circular slide rail 5 is an existing component, which further improves the support capacity of the elbow pipe 4 and does not affect the circumferential movement of the elbow pipe.

[0030] As shown in Figure 3 The upper side of the box body 12 is fixedly provided with an air pump 92, and the output end of the air pump 92 is communicated and assembled with one end of the elbow pipe 4 through a rotary joint 91, and the input end of the air pump 92 extends out of the support box 10; when the air pump 92 works, external air can be pressurized and input into the elbow pipe 4, and the arrangement of the rotary joint 91 can ensure continuous air supply without affecting the rotation of the elbow pipe 4.

[0031] The input end of the air pump 92 is communicated and provided with an air filter 93; the air filter 93 is an existing component, which avoids impurities in the external air from entering the elbow pipe 4, thereby avoiding the situation that the nozzle 2 is blocked or adhered to the wear-resistant steel casting.

[0032] As shown in Figure 2 Both sides of the box body 12 are fixedly provided with a pair of L-shaped guide plates 11, and a baffle 14 is slidably installed between each pair of L-shaped guide plates 11; the L-shaped guide plates 11 play a guiding role and improve the stability of the lifting of the baffle 14.

[0033] The lower side of the baffle 14 is fixedly provided with a rubber strip 15; when the baffle 14 moves downward to the lowest position, the rubber strip 15 abuts against the guide rail 1, so that the whole has the ability of braking and avoids the situation of running.

[0034] The working principle of the embodiment is as follows:

[0035] A controller is installed on the front side of the box body 12, and the electric components such as the electric lifting platform 8, the speed reducer 71 and the air pump 92 are electrically connected with the controller and are controlled by the controller.

[0036] The wear-resistant steel casting treated by the water toughening process is sequentially transferred and placed between the pair of guide rails 1 through the tray, and at this time, the wear-resistant steel casting still has a part of residual heat higher than room temperature and adhered water.

[0037] In the initial state, the electric lifting platform 8 is lifted by the supporting rod 6 to lift the two baffles 14, so as to expose the through slot 13, and the elbow pipe 4 is turned to the rear side to avoid affecting the passing of the wear-resistant steel casting.

[0038] In use, the staff pushes the box body 12, and then the box body 12 is moved to a wear-resistant steel casting along the guide rail 1, at this time, the baffle 14 is controlled to descend along the L-shaped guide plate 11, until the rubber strip 15 abuts against the guide rail 1, and the braking can also form a relatively isolated space inside.

[0039] Then, the air supply assembly 9 works, high-pressure gas is output through the elbow pipe 4 and the nozzle 2, and the driving assembly 7 rotates the elbow pipe 4, so that the wear-resistant steel casting inside can be circumferentially blown, the residual water can be blown dry, and after completion, the above-mentioned operation can be repeated to cool and dry the next wear-resistant steel casting, so as to avoid rust caused by residual water.

[0040] It is obvious for those skilled in the art that the present application is not limited to the details of the above-mentioned exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or basic characteristics of the present application. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-limiting, the scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application. Any reference signs in the claims should not be regarded as limiting the claims.

[0041] In addition, it should be understood that although the present application is described in the form of embodiments, not every embodiment contains only one independent technical solution, and the description manner of the specification is only for the sake of clarity, those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be properly combined to form other embodiments which can be understood by those skilled in the art.
