Description

Technical Field

[0001] This utility model relates to the field of impact hammer crusher accessories, and in particular to an efficient hammer switching device for impact hammer crushers. Background Technology

[0002] When the impact hammer crusher is working, the rotor rotates at high speed. After the material enters, it is crushed by impact with the hammers on the rotor, and then impacted again by the liner. Therefore, long-term collision will cause wear on the outer end of the hammer. After long-term use, the hammer needs to be disassembled and replaced, that is, the hammer needs to be flipped and reinstalled. Traditional switching devices are mostly hoisted and switched by two side booms. The side booms are equipped with pins, and then the hammer is flipped by the shaft handle. The multiple pins on both sides and the positioning after flipping are time-consuming, and the hammer itself is heavy, so flipping requires a lot of force. Utility Model Content

The bottom of the lifting frame has opposing sliding grooves, within which two opposing moving sliders are slidably installed. The main boom and the secondary boom are respectively mounted on the two opposing moving sliders. A labor-saving box is installed on one side of the main boom. A main disc shaft is rotatably mounted on the main boom. One end of the main disc shaft extends into the labor-saving box and is fitted with a large gear. The large gear meshes with a small gear, and a small gear shaft is mounted on the small gear. A main disc is mounted on the other end of the main disc shaft. A limit sleeve is rotatably mounted on the secondary boom. A limit pin is inserted into the limit sleeve. One end of the limit pin extends to the outside of the limit sleeve and is fitted with a secondary disc. A retaining ring is installed on the limit sleeve near the secondary disc. A spring is fitted on the limit pin between the retaining ring and the secondary disc. A pull-out cap is installed on the other end of the limit pin.

[0006] Furthermore, a bidirectional threaded screw is rotatably installed in the opposing slide groove. The bidirectional threaded screw is screwed together with the two opposing moving sliders. One end of the bidirectional threaded screw extends to the outside of the lifting frame and is equipped with a torque.

[0007] Furthermore, the limiting plug consists of a column and a limiting protrusion mounted on the column, and the limiting sleeve is provided with a limiting hole corresponding to the limiting plug.

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] like Figure 1-5 As shown, a high-efficiency switching device for impact hammer crushers consists of a hoisting frame 1, a main boom 3, and a secondary boom 4.

[0021] The bottom of the hoisting frame 1 is provided with opposing slide grooves 18, and two opposing moving sliders 2 are slidably installed in the opposing slide grooves 18. The main arm 3 and the auxiliary arm 4 are respectively installed on the two opposing moving sliders 2. A labor-saving box 6 is installed on one side of the main arm 3. A main disk shaft 5 is rotatably installed on the main arm 3. One end of the main disk shaft 5 extends into the labor-saving box 6 and is equipped with a large gear 22. The large gear 22 is meshed with a small gear 21. A small gear shaft 20 is installed on the small gear 21. It achieves labor saving through gear transmission. The other end of the main disk shaft 5 is equipped with a main disk 7.

[0022] A limiting sleeve 15 is rotatably installed on the auxiliary arm 4. A limiting pin 17 is inserted inside the limiting sleeve 15. One end of the limiting pin 17 extends to the outside of the limiting sleeve 15 and is fitted with a secondary plate 12. A retaining ring 14 is installed on the side of the limiting sleeve 15 near the secondary plate 12. A spring 13 is fitted on the limiting pin 17 between the retaining ring 14 and the secondary plate 12. A pull cap 16 is installed on the other end of the limiting pin 17.

[0023] like Figures 1-5 As shown, this utility model also discloses the following more optimized specific structures:

[0024] A bidirectional threaded screw 19 is rotatably installed in the opposing slide groove 18. The bidirectional threaded screw 19 is screwed together with two opposing moving sliders 2 to facilitate their opposing drive. One end of the bidirectional threaded screw 19 extends to the outside of the lifting frame 1 and is equipped with a knob 10.

[0025] The limiting plug 17 consists of a plug body 171 and a limiting protrusion 172 installed on the plug body 171. The limiting sleeve 15 is provided with a limiting hole corresponding to the limiting plug 17.

[0026] One end of the pinion shaft 20 extends to the outside of the force-saving box 6 and is fitted with a crank handle 8.

[0027] Pins 11 are installed on the surfaces of both the main plate 7 and the auxiliary plate 12.

[0028] A lifting ring 9 is installed on the top of the lifting frame 1.

[0029] like Figures 1-5 When using the high-efficiency hammer switching device for the impact hammer crusher shown, the lifting frame 1 is lowered to the vicinity of the hammer. Then, the limiting pin 17 is inserted and removed so that the distance between the main plate 7 and the auxiliary plate 12 is wider than the length of the hammer. This allows for quick alignment of the insertion hole. The pin is then released to ensure quick alignment. Under the action of the spring, the pin enters the holes on both sides of the hammer. The crank handle 8 is turned to rotate the hammer and maintain its direction. Due to the force-saving gear structure of the force-saving box 6, the hammer rotates easily and does not require continuous high force to maintain its state, making hammer switching convenient.

[0030] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of this utility model as claimed.
