[0033] The utility model is further described below in combination with the drawings and examples.

[0034] As Figures 1-6 shown, a head wheel tile suitable for steel wire lifting belt, comprising a plurality of circumferentially arranged arc-shaped metal tiles 2 around the head wheel body 1, the outer side of the metal tile 2 is provided with arc-shaped rubber tile 3, the inner side of the rubber tile 3 is provided with arc-shaped groove 4, the shape of the arc-shaped groove 4 is adapted to the shape of the metal tile 2;The inner side of the metal tile 2 is provided with a plurality of insertion cylinders 5, the arc-shaped groove 4 is provided with a plurality of insertion rods 6 adapted to the insertion cylinder 5, the insertion rod 6 is sleeved in the corresponding insertion cylinder 5, the circumferential direction of the head wheel body 1 is provided with a plurality of insertion holes 7 adapted to the insertion cylinder 5, the axial direction of the head wheel body 1 is provided with a plurality of fixing holes 8 penetrating through the corresponding insertion hole 7, the insertion cylinder 5 and the insertion rod 6, the fixing hole 8 is provided with fixing bolt 9. The cooperation of the insertion cylinder 5 and the insertion rod 6 can accurately position the metal tile 2 and the rubber tile 3 during installation, ensure that the two are closely attached, and enhance the stability of the connection between the two. During the operation of the head wheel, the displacement or shaking of the rubber tile 3 relative to the metal tile 2 can be effectively prevented, thereby prolonging the service life of the rubber tile 3 and the metal tile 2 and ensuring the overall performance stability of the head wheel tile. The metal tile 2, the rubber tile 3 and the head wheel body 1 are firmly connected together by the fixing bolt 9 penetrating through the insertion hole 7, the insertion cylinder 5 and the insertion rod 6. This connection mode can withstand a large tensile force and torque, ensuring that the head wheel tile will not loosen or fall off when rotating at high speed and bearing a large load, improving the safety and reliability of the head wheel operation. At the same time, the wear of the steel wire lifting belt is small, greatly improving its service life.

[0035] A plurality of the insertion cylinder 5 and the insertion hole 7 are both arranged towards the axis of the head wheel body 1. The insertion cylinder 5 and the insertion hole 7 are arranged towards the axis, so that the fixing bolt 9 can better evenly transmit the stress of the head wheel tile to the entire head wheel body 1 after installation. Local stress concentration caused by uneven stress is avoided, the wear of the head wheel body 1 and the head wheel tile is reduced, and the overall structural strength and stability of the head wheel is improved.

[0036] The rubber tile 3 is provided with an annular stopper 10 at both ends, and the inner sides of the two stoppers 10 abut against the two ends of the head wheel body 1. The annular stopper 10 plays a limiting and protective role. On the one hand, it can prevent the rubber tile 3 from moving in the axial direction, ensuring that the rubber tile 3 always maintains the correct relative position with the head wheel body 1; on the other hand, the stopper 10 can block dust, debris and other foreign matter from entering the connection part of the head wheel tile and the head wheel body 1, reducing wear and failure caused by foreign matter invasion and prolonging the service life of the head wheel.

[0037] The stopper 10 is provided with a positioning hole 11 adapted to the fixing hole 8. The positioning hole 11 makes it more convenient and accurate to install the fixing bolt 9. The installer can quickly align the fixing hole 8 through the positioning hole 11, improving the installation efficiency and ensuring the installation accuracy, so as to ensure that the head wheel tile can be correctly installed on the head wheel body 1 and improve the assembly quality of the head wheel.

[0038] A sealing rubber strip 12 is arranged between the two adjacent metal tiles 2. The sealing rubber strip 12 can fill the gap between the adjacent metal tiles 2, preventing dust, moisture and other impurities from entering the inside of the head wheel. This helps to keep the inside of the head wheel clean, reduces failure caused by impurities wear, and improves the running stability and reliability of the head wheel. At the same time, the sealing rubber strip 12 can also play a certain buffering role, reducing the friction and collision noise between the metal tiles 2.

[0039] The sealing rubber strip 12 is a silica rubber sealing rubber strip 12 with activated carbon particles. Silica rubber has good elasticity, high and low temperature resistance and aging resistance, and can maintain stable sealing performance in different working environments. Activated carbon particles have adsorption effect, which can adsorb harmful gases, odors and small particles in the surrounding environment, further purifying the working environment inside the head wheel, reducing corrosion and pollution to the rubber tile 3 and the metal tile 2, and prolonging the service life of the head wheel tile.

[0040] The cross section of the sealing rubber strip 12 is trapezoidal, the upper base width between the two adjacent sealing rubber strips 12 is less than the width of the metal tile 2, and the lower base width between the two adjacent sealing rubber strips 12 is greater than the width of the metal tile 2. The trapezoidal cross section of the sealing rubber strip 12 can better fit closely with the adjacent metal tile 2. The narrower upper base facilitates insertion into the gap between the adjacent metal tiles 2, while the wider lower base provides a larger sealing area, enhancing the sealing effect. This design makes the sealing rubber strip 12 not easy to fall off after installation, effectively preventing dust and moisture from entering, and improving the sealing performance and protection performance of the head wheel.

[0041] A plurality of buffer protrusions 13 are arranged on the outer surface of the rubber tile 3 at intervals in the circumferential direction. The buffer protrusions 13 can play a buffering role when the steel wire lifting belt contacts the rubber tile 3. When the steel wire lifting belt impacts the rubber tile 3, the buffer protrusions 13 can absorb and disperse the impact force, reduce the direct pressure on the rubber tile 3, reduce the wear rate of the rubber tile 3, and prolong the service life of the rubber tile 3. At the same time, the buffering effect can also reduce the friction noise between the steel wire lifting belt and the rubber tile 3, and improve the working environment.

[0042] The buffer protrusions 13 are semispherical buffer protrusions 13, the height of the buffer protrusions 13 is 5-10mm, and the distance between adjacent two buffer protrusions 13 is 20-50mm. The semispherical buffer protrusions 13 have good mechanical properties and can uniformly disperse the impact force. The design of the height of 5-10mm can provide sufficient buffer space and will not affect the normal operation of the steel wire lifting belt. The arrangement of the distance of 20-50mm between adjacent buffer protrusions 13 can ensure that the buffer protrusions 13 are evenly distributed on the outer surface of the rubber tile 3, so that the entire rubber tile 3 can effectively play a buffering role and improve the uniformity and stability of the buffering effect.
