Description

Technical Field

[0001] This invention belongs to the field of mining vehicles, specifically, it relates to a method for limiting the wheel, rim pressing block and locking ring of a mining vehicle. Background Technology

[0002] like Figure 1 The image shown is an exploded axonometric view of a five-piece wheel rim for a mining vehicle under existing technical conditions.

[0003] Mining cars are large-scale transportation equipment used in open-pit mines for transporting materials. They utilize giant engineering tires and five-piece rims. The rim 4 consists of a rim body 41, a seat ring 42, a locking ring 43, a first retaining ring 44, and a second retaining ring 45. The seat ring 42, the first retaining ring 44, and the second retaining ring 45 are fitted onto both sides of the outer circumference of the rim body 41. The first retaining ring 44 is limited by the flange of the rim body 41, and the seat ring 42 is located in the inner hole of the second retaining ring 45. After the tire 1 is installed on the rim 4, the tire 1 is located between the first retaining ring 44 and the second retaining ring 45. The locking ring 43 is engaged with the groove of the rim body to achieve axial positioning of the tire 1 and the various components of the rim 4. For ease of installation, the locking ring 43 is provided with a radial opening.

[0004] However, the mine roads are in poor condition. During operation, tire 1 is subjected to impacts from the road surface, and the axial force of tire 1 repeatedly acts on the rim 43, making it very easy for the rim 43 to pop out. In addition, when tire 1 is inflated, the change in tire pressure also poses a risk of the rim 43 popping out. If the rim 43 pops out, it will directly cause other parts of the rim 4 to break off under the action of tire pressure, posing a serious safety risk to people around the vehicle. Summary of the Invention

[0005] The purpose of this invention is to provide a method for limiting the locking ring of a mining car wheel, rim pressure block, and locking ring. When the locking ring tends to pop out of the groove of the rim body, the extension of the rim pressure block limits the locking ring from the outside to prevent it from popping out of the groove of the rim body.

[0006] To achieve the above objectives, the technical solution used in this invention is: The rim clamping block includes: a base, a first support protrusion, a second support protrusion, and an extension. The first support protrusion, the second support protrusion, and the extension are disposed on the front side of the base. The second support protrusion is located above the first support protrusion, and the extension is located above the second support protrusion. A through hole is provided between the first support protrusion and the second support protrusion. The extension length of the extension is greater than the height of the first support protrusion and the second support protrusion.

[0007] Furthermore, the base, the first support protrusion, the second support protrusion, and the extension have the same width, and the base is in the shape of a cuboid.

[0008] Furthermore, the back of the base is provided with reinforcing ribs, the first support protrusion and the second support protrusion extend in the transverse direction, and the reinforcing ribs extend in the longitudinal direction.

[0009] Furthermore, the extension is perpendicular to the base.

[0010] A mining truck wheel includes a hub and a rim. The rim includes a rim body, a seat ring, and a locking ring. The seat ring is fitted onto the outer circumferential surface of the rim body, and the locking ring is installed in a groove on the outer circumferential surface of the rim body and contacts the seat ring through a conical surface. The wheel wheel is characterized by further including a rim clamping block as described in any one of claims 1-3. The hub is located within the inner hole of the rim body, and the inner conical surface of the rim body contacts the outer conical surface of the hub. The rim clamping block is located outside the hub and rim. The end face of the hub is provided with multiple threaded holes evenly distributed along the circumferential direction. One end of a stud is installed in the threaded hole of the hub, and the other end passes through the through hole of the rim clamping block to connect to a nut. A first supporting protrusion abuts against the upper end face of the hub stop, a second supporting protrusion abuts against the end face of the rim body, and an extension is located above the locking ring.

[0011] Preferably, the bottom surface of the rim clamping block contacts the outer peripheral surface of the stop on the end face of the hub, and the nut is located on the outside of the rim clamping block, pressing the rim clamping block tightly onto the end face of the hub and the rim.

[0012] Preferably, the extension extends toward the rim side to above the outer peripheral surface of the lock ring, with a gap maintained between the extension and the outer peripheral surface of the lock ring, and a gap maintained between the left end face of the extension and the end face of the seat ring.

[0013] Preferably, multiple rim pressure blocks are evenly distributed and installed on the end face of the wheel hub along the circumferential direction, and the extensions surround the outer circumferential surface of the lock ring.

[0014] Preferably, a tire, a first retaining ring, and a second retaining ring are mounted on the outer peripheral surfaces of the rim body and the seat ring. The first retaining ring is located between the tire and the flange of the rim body, and the second retaining ring is located between the tire and the flange of the seat ring. The first and second retaining rings provide lateral support for the tire, and a sealing ring is installed between the seat ring and the rim body.

[0015] Locking ring limiting methods include: After the rim clamping blocks are installed, the extension of each rim clamping block wraps around the outer side of the lock ring in a circumferential direction, presenting a wrapping shape; When the tire is impacted by the road surface or impacted axially with the rim ring during inflation, and the rim ring tends to pop out of the groove of the rim body, the extension of the rim retainer blocks from the outside to limit the rim ring and prevent it from popping out of the groove.

[0016] The technical effects of this invention include: After the rim retainer blocks are installed, their extensions do not affect the rim seat ring and the rim lock ring. When all rim retainer blocks are installed, the extension of each rim retainer block wraps around the outer circumference of the rim lock ring, confining it within the grooves of the rim body. When the tire is impacted or when it impacts the rim lock ring axially during inflation, causing the rim lock ring to tend to pop out of the grooves of the rim body, the extensions of the rim retainer blocks limit the rim lock ring from the outside, preventing it from popping out of the grooves of the rim body, thus improving safety.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0022] The following is a detailed description of the specific implementation method of the mining wheel rim pressure block with locking ring limiting function and the limiting method involved in this invention.

[0023] like Figure 2 The image shown is a front axonometric view of the rim clamping block involved in this invention; as shown... Figure 3 As shown, this invention relates to a rear isometric view of a rim clamping block.

[0024] Hereinafter, the side of the rim pressure block 5 with the supporting protrusions (first supporting protrusion 53 and second supporting protrusion 54) will be referred to as the front side, and conversely, the side with the reinforcing ribs 56 will be referred to as the back side.

[0025] The rim clamping block 5 has a cuboid-shaped base 51. A first support protrusion 53 and a second support protrusion 54 extending laterally along the width direction are provided on the front side of the base 51. The first support protrusion 53 is located on the lower side of the front side and connects to the bottom surface, while the second support protrusion 54 is located above the first support protrusion 53. A through hole 55 is provided between the first support protrusion 53 and the second support protrusion 54. An extension 52 is provided on the front side of the base 51, located above the second support protrusion 54. The width of the extension 52 is equal to that of the base 51, and its extension length is greater than that of the first support protrusion 53 and the second support protrusion 54.

[0026] The base 51 has two reinforcing ribs 56 extending along the length direction (longitudinal direction) on both sides of its back surface. The reinforcing ribs 56 are located at the left and right edges of the back surface, and the reinforcing ribs 56 improve the rigidity of the base 51. The extension 52 is perpendicular to the base 51.

[0027] like Figure 4 The diagram shown is a schematic diagram of the rim clamping block 5 after installation in this invention; as shown... Figure 5 As shown, is Figure 4 A cross-sectional view along the QQ direction; such as Figure 6 As shown, is Figure 5 A magnified view of the S-position.

[0028] After the tire 1 is installed on the rim 4, the inner bore of the tire 1 is supported on the rim body 41 and the seat ring 42, and the rim body 41 and the seat ring 42 provide radial support for the tire.

[0029] A first retaining ring 44 is installed between the sidewall of tire 1 and the rim body 41, and a second retaining ring 45 is installed between the sidewall of tire 1 and the flange of the seat ring 42. The first retaining ring 44 and the second retaining ring 45 provide lateral support for tire 1. A locking ring 43 is installed in a groove on the outer circumferential surface of the rim body 41 and contacts the seat ring 42 through a conical surface, thereby limiting the axial movement of the seat ring 42. A sealing ring 3 is installed between the seat ring 42 and the rim body 41, forming a closed space inside the tire 1. When tire 1 is inflated, the internal air pressure increases, and the axial force of tire 1 is entirely borne by the locking ring 43. Correspondingly, when the mining truck is in operation, the axial force generated by tire 1 when it is impacted by the road surface is also borne by the locking ring 43.

[0030] The hub 2 is located within the inner hole of the rim body 41, which is connected to the hub 2 via studs 6 and nuts 7. The outer edge of the hub 2 has a 28° angled outer conical surface 2a, and the inner hole of the rim body 41 has a 28° angled inner conical surface 41a near the locking ring 42. After the rim 4 is installed onto the hub 2, the inner conical surface 41a of the rim body 41 contacts the outer conical surface 2a of the hub 2. The rim 4, with the tire 1 mounted on it, is clamped to the hub with the 28° angled outer conical surface using several rim clamping blocks, thus achieving a fixed connection between the rim and the hub.

[0031] The end face of the hub 2 is provided with multiple threaded holes evenly distributed along the circumference. The left end of the stud 6 passes through the through hole 55 of the rim pressure block 5 and connects to the threaded hole of the hub 2, and is evenly distributed along the circumference.

[0032] The bottom surface of the rim pressure block 5 contacts the outer peripheral surface of the stop on the right end face of the hub 2. The first support protrusion 53 abuts against the right end face of the hub 2 above the stop. The second support protrusion 54 abuts against the right end face of the rim body 41. The extension 52 is located above the lock ring 43. The nut 7 is located on the right side (outer side) of the rim pressure block 5 and is tightened on the stud 6. The nut 7 presses the rim pressure block 5 against the end faces of the hub 2 and the rim 4.

[0033] At this time, the first support protrusion 53 contacts the end face of the hub 2, and the second support protrusion 54 contacts the end face of the rim body 41. The clamping force of the nut 7 is transmitted through the rim clamping block 5, causing the inner conical surface 41a of the rim 4 to press against the outer conical surface 2a of the hub 2, thereby achieving a fixed connection between the rim 4 and the hub 2.

[0034] Multiple rim clamping blocks 5 are evenly distributed along the circumference and installed on the end face of the wheel hub 2. After the rim clamping blocks 5 are installed, their extensions 52 extend towards one side of the rim 4 to above the outer circumferential surface of the lock ring 43. There is a small gap between the extensions 52 and the outer circumferential surface of the lock ring 43. Similarly, there is a small gap between the left end face of the extensions 52 and the end face of the seat ring 42. The extensions 52 of the rim clamping blocks 5, evenly distributed along the circumference of the wheel hub 2, surround the outer circumferential surface of the lock ring 43.

[0035] The present invention further provides a locking ring limiting method, comprising: After the rim clamping block 5 is installed, its extension 52 extends from the base 51 toward the rim 4 side to the top of the outer peripheral surface of the lock ring 43. There is a small gap between the left end face of the extension 52 and the seat ring 42, and there is also a small gap between the extension 52 and the outer peripheral surface of the lock ring 43. That is, after the rim clamping block 5 is installed, the extension 52 will not affect the rim seat ring 42 and the lock ring 43.

[0036] After all the rim clamps 5 are installed, the extension 52 of each rim clamp 5 surrounds the outer side of the outer circumferential surface of the lock ring 43 in a circumferential direction, forming a wrapping shape. When the tire 1 is impacted by the road surface or impacts the lock ring 43 axially during inflation, causing the lock ring 43 to tend to pop out of the groove of the rim body 41, the extension 52 of the rim clamp 5 limits the lock ring 43 from the outside, preventing it from popping out of the groove of the rim body 41, thereby improving safety.

[0037] The mining wheel rim clamping block according to the above scheme can restrict the pop-out of the locking ring 43 while clamping the wheel rim 4 and the wheel hub 2. Moreover, it is easy to operate and has good reliability.

[0038] The terminology used in this invention is descriptive and exemplary, not restrictive. Since this invention can be embodied in many forms without departing from the spirit or essence of the technical solution, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
