Description

Technical Field

[0001] This utility model relates to the technical field of tipper synchronous shaft protective cover device, and in particular to a tipper synchronous shaft protective cover device that can discharge ash and is easy to maintain. Background Technology

[0002] During the operation of a tippler, the synchronous shaft is a key component, and its stable operation is crucial. The synchronous shaft typically rotates at high speed and is subjected to significant torque and vibration. This device mainly consists of the following parts: a main protective shell and a maintenance structure. The main protective shell is made of high-strength steel, possessing excellent rigidity and protective performance, effectively preventing material splashing and external impurities from entering, protecting the synchronous shaft from damage. Existing publication (announcement) number: CN207497711U, entitled "A Steel Structure Support for a Tippler Synchronous Shaft," includes a main support, intermediate legs, diagonal legs, a large base plate, a small base plate, a pad, and a horizontal tie beam. The large and small base plates are fixed to the concrete ground, the main support is fixed to the large base plate, the intermediate and diagonal legs are fixed between the main support and the small base plate, and the horizontal tie beam is fixed to the upper part of the main support. This utility model can withstand stress in all directions during tippler unloading operations, while also considering existing space limitations. It is quick and efficient to install, improving the reliability of the equipment.

[0003] However, the protective coating on the steel structure support of the aforementioned tipper's synchronous shaft may be damaged due to wear, collision, or other reasons during long-term use. Once the coating is damaged, the metal substrate will be exposed to the external environment, which will cause corrosion. Furthermore, after long-term operation, a large amount of dust may accumulate on the synchronous shaft. This dust not only affects the heat dissipation of the equipment but may also cause corrosive gases and dust in the air to be adsorbed on the surface of the synchronous shaft, leading to long-term exposure of the synchronous shaft to such an environment, resulting in rust and eventually breakage. Therefore, the above-mentioned technical problems need to be addressed. Utility Model Content

[0006] Preferably, the protective cover is composed of upper and lower semi-arc covers, with the two ends of the lower arc cover fixed between protective rings, and the arc covers are hinged to each other.

[0007] Preferably, ash discharge holes are provided at equal intervals on the lower arc-shaped cover, and the ash discharge holes penetrate the lower arc-shaped cover.

[0008] Preferably, square through-holes are provided on both sides of the lower arc-shaped cover, and rubber blocks are movably engaged inside the arc-shaped cover through the square through-holes. A pull rod is engaged at one end of each rubber block.

[0009] Preferably, the transmission mechanism includes a rotating rod rotatably mounted between the protective rings, the rotating rod being a reciprocating lead screw, and an auxiliary gear fixedly connected to one side of the rotating rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: In this utility model, the protective cover and the dust discharge hole cooperate with each other to facilitate the protection of the synchronous shaft and to discharge dust, thereby improving the stability of the synchronous shaft protective cover device and realizing the functions of synchronous shaft protection and dust discharge. Furthermore, the rotating rod and the cleaning ring cooperate with each other to facilitate the cleaning of dust on the synchronous shaft and the inside of the protective cover, thereby improving the efficiency of internal dust cleaning and realizing the dust removal function of the device.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example: See Figure 1-5 This utility model discloses a ash-discharging and maintenance-friendly protective cover device for the synchronous shaft of a tipper. It includes a synchronous rotating shaft 1, with bearings 3 equidistantly sleeved on the shaft 1. Protective rings 4 are sleeved on the outer sides of the bearings 3, and a protective cover 2 is fixedly connected between the protective rings 4. A cavity is formed between the inner side of the protective cover 2 and the synchronous rotating shaft 1, and a transmission mechanism is installed inside the protective cover 2. A cleaning mechanism is installed on the transmission mechanism. Through the protective rings 4 and the protective cover 2, material splashing and external impurities can be effectively blocked, protecting the synchronous rotating shaft 1 from damage. The protective cover 2 is composed of upper and lower semi-arc-shaped covers. The two ends of the lower arc-shaped cover are fixed between the protective rings 4, and the arc-shaped covers are hinged to each other. The upper and lower semi-arc-shaped covers facilitate maintenance of the internal components of the protective cover 2. Ash discharge holes 5 are equidistantly opened on the lower arc-shaped cover, penetrating the lower arc-shaped cover, allowing dust to be discharged from the protective cover 2.

[0021] In this invention, square through-holes are provided on both sides of the lower arc-shaped cover. A rubber clamp is movably engaged inside the arc-shaped cover through the square through-holes. A pull rod 6 is engaged at one end of each rubber clamp, allowing larger dust or impurities to be discharged from the protective cover 2. The transmission mechanism includes a rotating rod 7 rotatably mounted between the protective rings 4. The rotating rod 7 is a reciprocating screw, and an auxiliary gear 8 is fixedly connected to one side of the rotating rod 7. The rotating rod 7 can rotate through the interaction with the auxiliary gear 8. The cleaning mechanism includes a rotating gear 10 meshing with the auxiliary gear 8. The rotating gear 10 is sleeved and fixed to the outside of the synchronous rotating shaft 1. A cleaning ring 9 is slidably mounted on the rotating rod 7 corresponding to the auxiliary gear 8. The inner wall of the cleaning ring 9 is tightly fitted to the outside of the synchronous rotating shaft 1, allowing the synchronous rotating shaft 1 to rotate, thereby cleaning the synchronous rotating shaft 1 and the inside of the protective cover 2.

[0022] Working Principle: When using this invention, the synchronous rotating shaft 1 is first rotated by starting the tipper, which in turn rotates the inner ring of the bearing 3. The other side of the protective ring 4 should be fixed to the iron frame. Then, the protective cover 2, which consists of upper and lower semi-circular covers, is easy to open for internal inspection. The rotating gear 10, which is fixed to the outside of the synchronous rotating shaft 1, rotates accordingly, thereby driving the auxiliary gear 8 and the rotating rod 7 to rotate. The rotating rod 7 is a reciprocating screw, which drives the cleaning ring 9 to reciprocate along the synchronous rotating shaft 1 and the inside of the protective cover 2, cleaning the dust and other impurities attached to the synchronous rotating shaft 1 and the protective cover 2. The cleaned dust can then be directly discharged through the dust discharge hole 5. At the same time, the pull rod 6 can be pulled out to disengage the rubber block from the protective cover 2, which improves the dust discharge efficiency, reduces malfunctions caused by dust accumulation, and improves the reliability of the equipment.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
