The inner mounting surface is provided with a plurality of tabs and a lock which cooperate to securely attach the wear cap to the wearable surface. The tabs are inclined in a uniform direction at an acute angle to the mounting surface to minimize the amount of travel needed to install and remove the wear cap. The lock has a rigid hub and a shaft. The hub includes a pair of bearing faces which interact with the wear cap and the wearable surface to effectively prevent loss of the wear cap during use.
Description
The present invention relates to wear parts, more particularly, relate to wear-resisting cover and protect wear surface.
Excavating equipment can run into this situation in common use, promptly parts are subjected to heavy wear.For prolonging the application life of this equipment, wear-resisting cover is installed on the surface of degree of wear maximum is attempted.For example, at the United States Patent (USP) Re.33 of Potter, 454 and people's such as Jones United States Patent (USP) 5,241,765 in, proposing provides wear-resisting cover along the wall of Excavating bucket.Wear-resisting cover also is used to cover the expose portion of a coupling apparatus, as United States Patent(USP) Nos. 4,326,348 at Emrich, and people's such as Hahn 4,335,532, disclosed in 4,716,667 United States Patent (USP)s such as grade of 4,428,131 and the Martin of Emrich.
Wear-resisting cover usually has a groove, and this groove is used for receiving one and is installed to a tongue of wanting on the wear surface of guard block.This groove is a T shape structure (for example, U.S. Patent No. 4,335,532) or a dovetail structure (for example, U.S. Patent No. Re.33,454) substantially, breaks away from from wear surface to prevent wear-resisting cover.Though a groove was enough to wear-resisting cover is fixed on the wear surface with being connected of tongue, it produces undesired restriction to the design of wearing terrain sometimes.Specifically, adopting the groove and the connection of tongue to fix wear-resisting cover requires wearing face to have a relative flat or linear shape.Therefore, as U.S. Patent No. 4,335, shown in 532, the wear surface of coupling apparatus is made into a rectangular T shape tongue.This tongue structure need use lot of materials so that coupling apparatus has sufficiently high intensity.
And the linkage of tongue and groove needs wear-resisting cover to move axially so that install and remove in a quite long distance (be up to its length 100%) usually.The dismounting of wear-resisting cover will be through the slip of a long distance, and when wear-resisting cover was closely tamped by soil particle, it was very difficult to have confirmed to finish this process.Also have, wear-resisting cover this moves axially frequent other parts (such as, sharp shaped material) that need to remove, so that enough gaps are provided.
Generally, wear-resisting cover relies on the linkage of other wear parts to be fixed on its correct position.For example, at United States Patent(USP) Nos. 4,335, disclosed each wear-resisting cover is all by being connected to a sharp shaped material on the wear surface that is fixed on the coupling apparatus separately in 532 and 4,716,667.Consequently, even under the situation that this point dress thing itself does not need to change, also must often move this sharp shaped material to change damaged wear-resisting cover.And, if sharp shaped material in use damages, when can causing wear-resisting cover and sharp shaped material, the non-independent installation of so this wear-resisting cover loses.Also have, interconnecting of two wear parts can need be caused one more because of the installation process of difficulty.
The present invention relates to protect with a wear-resisting cover wear surface of a frayed structure member, this wearing and tearing are because the relative slip with another kind of material of this structure member causes, as in the situation that excavating equipment experienced.Wear-resisting cover of the present invention is fixed on the wear surface by joint and being used in combination of a locking device.This wear-resisting cover is particularly suitable for being connected on the flat or uneven surface.Like this, just can avoid limiting the design on the connection surface that is used for wear-resisting cover.
The linkage that makes wear-resisting cover that mutually combines of joint and locking device has had higher intensity, and this wear-resisting cover connector system can be fixed to wear-resisting cover on the wear surface independently.In this way, even under the situation of sharp shaped material or the damage of other wear parts, wear-resisting cover also can remain attached on the wear surface.In some cases, the independent installation also makes wear-resisting cover to be removed need not to move under other component condition.
The installation surface inclination in an acute angle of the wear-resisting relatively cover of the joint that stretches out reaches minimum so that install and remove the required amount of movement of wear-resisting cover.This structure also makes and need not move other parts and remove or install the needed gap of wear-resisting cover and minimize.The joint that tilts also makes and is easy to remove wear-resisting cover under the situation around soil particle closely tamps parts.
Locking device has the lining and the axle of a rigidity.This lining comprises a pair of load-bearing surface, and this a pair of load-bearing surface and wear-resisting cover and wear surface interact to prevent wear-resisting the losing in the use that cover on effectively.Locking device is installed with the rotation lining between an off-position and a latched position.The use of this lining simple rotation can make locking device no matter by soil particle how closely compacting all be easy to be released.

According to the present invention, wear-resisting cover is used to protect the surface of in use being worn and torn.In this uses, the described wear-resisting wear surface that meter is used for protecting a tooth that is covered with of one embodiment of the invention.But the present invention is not limited thereto.But wear-resisting cover of the present invention can be used for a wideer scope, promptly is used for protecting owing to the relative various excavating equipments that are worn and the wear surface on the miscellaneous equipment (for example, ore chute) of sliding with another kind of material.Be appreciated that following described identical notion and the structure that is used for wear-resisting cover will be applicable to that design is used for being connected to the wear-resisting cover on other wear surface.
In common use, tooth may be in multiple different orientation.But parts are described with relative terms sometimes described in this uses, such as upper and lower for convenience of description.These directions are interpreted as the orientation with respect to the parts shown in Fig. 1, other have explanation except.
The wear-resisting cover 10 of the present invention comprises an external surface or wearing face 14, inner surface or installation surface 16, antetheca 18, a rear wall 20 and a pair of sidewalls 22,24 (seeing Fig. 1-2 and 4-10).Though wear-resisting cover preferably is roughly the rectangle with four peripheral walls, also can adopt other structure.
In the present embodiment, wear-resisting cover 10 is designed to be connected on the coupling apparatus 28 of a tooth 25 (seeing Fig. 1-3).This coupling apparatus comprises 30, the 31 and noses 33 that are used to install another wear parts 35 of a pair of bifurcated pillar that are installed on the bucket lip.Though pillar 30,31 preferably is soldered on the leading edge, they also can connect by mechanical device.Wear-resisting cover 10 is connected on the wear surface 29 of top struts 30, and this top struts 30 is located immediately at the rear of nose 33.Wear surface 29 comprises a central surface 37 and pair of angled side 39.Central surface 37 is roughly a convex-shaped in the longitudinal direction.Side 39 is preferably flat, protrudes slightly or recessed curvature but also can have.So after the structure, wear surface 29 horizontal and vertical all be roughly nonlinear.
Wearing and tearing cover 10 has one as the crooked structure of bow, and this structure is recessed into substantially along its installation surface 16, and protrudes substantially along its wear surface 14, like this its shape with wear surface 29 (seeing Fig. 2 and 5-10) mutually unanimous on the whole.Installation surface 16 have a core 32 and a pair of be flat flank part 34 (but this flank part also can be to protrude slightly or recessed) substantially, this core 32 be substantially be recessed into the lid central surface 37 on, flank part 34 is covered on side 39.When flank part 34 with after side 39 engages, core 32 preferably and central surface 37 certain intervals is arranged.
(see Fig. 2 and 5-7) by using joint 36,38 and locking device 40 that wear-resisting cover 10 is fixed on the wear surface 29.Each joint 36,38 from installation surface 16 outwards, extending back limits a securing member of opening backward.In optimum structure, have three joints so that firmly and evenly be connected with wear surface.Two front connectors 36 place the position with the antetheca of wear-resisting cover and sidewall 18,22,24 attached neighbours' flank part 34 lateral alignment.Back joint 38 is positioned on the center at front connector 36 rears on the core 32.Because only one and cooperatively interact of back joint 38, so that it cans be compared to each front connector most is 36 wideer, more greatly with locking device 40.Joint also can be arranged on the diverse location or have different size.In addition, can also only use two joints or use four joints or more joint fixes the wear-resisting cover of the present invention.
For ease of connecting wear-resisting cover 10, wear surface 29 comprises that three grooves 42,44 are used to receive joint 36,38 (seeing Fig. 2 and 3).The formation of each groove 42,44 all defines a clamping convex shoulder 46,48.Therefore the shape of groove is the mirror image of joint 36,38 shapes, has just formed the groove 42 of two lateral alignment on the position of close side 39 front ends, on central surface 37, formed a center to rearward recess 44.When the size of front end groove 42 during basically with front connector 36 big or small consistent, rearward recess 44 extends forward to receive locking device 40.
Each joint 36,38 (seeing Fig. 2,5 and 6) all tilts with a summation equidirectional apparent surface 32,34, and these joints preferably extend from these surfaces 32,34 with a sharp angle that is about 30 °; Though can adopt other gradient, used angle should be less than about 45 °.Equally, convex shoulder 46,48 is with identical with joint 36,38 basically gradient extend internally (seeing Fig. 2 and 3).Joint 36,38 is placed in and engages in the groove 42,44 and with convex shoulder 46,48 to prevent that wear-resisting cover 10 from moving with respect to wear surface 29 backward with on the outside direction.The dismounting of wear-resisting cover 10 can just engage desired as joint 32,34 with convex shoulder 46,48 by realizing with the wear-resisting cover that moves up forward.
Because joint is that tilt and shorter relatively,, wear-resisting cover 10 can realize effectively removing so only need moving forward once the distance that approximates its whole length 1/10th.Consequently, between wear-resisting cover 10 and wearing terrain 35, only need a very little gap 56, just can under the situation that need not to remove the wearing terrain 35 that is installed on the nose 33, pull down wear-resisting cover (see figure 1).In view of soil particle can closely be filled in the gap 56 usually, narrow gap will prevent material flowing betwixt effectively.Like this, the coupling apparatus part that is exposed in the gap 56 just can be protected, and avoids the excessive wear of compacted granules.In addition, how not fine and close tube particle is, and wear-resisting cover 10 is removed to get up also to be easier to relatively, because it is very little to remove the needed amount of movement of wear-resisting cover.
The invention provides a releasable locking mechanism 40 and remove (seeing Figure 11-20) from wear surface 29 to prevent wear-resisting cover 10.Locking device 40 comprises a rigid liner 64, and this lining 64 is a single block preferably, before having and back bearing surface 66,68 and peripheral wall 70,72.In optimum structure, each in the bearing surface 66,68 all has a semicircle structure.Peripheral wall 70 forms an arc structure, and this structure is consistent with about 180 °-240 a ° circular arc substantially.Peripheral wall 72 is a flat part that links to each other with the two ends of wall 70 substantially.Preceding and rear axle 74,76 is aimed at from bearing surface 66,68 with the central line of peripheral wall 72 and is laterally outwards vertically stretched out.In optimum structure, axle 74,76 is positioned at the center of arc of peripheral wall 70.As described below, this arrangement allows rotational locking device under the situation that does not need to break up the particle binding that exists between the locking device compressed soils particle on every side.Correspondingly, axle 74,76 is positioned at prejudicially on the bearing surface 66,68 and (that is, departs from the geometric center of bearing surface), and adjacent with peripheral wall 72, when locking device swayed, lining 64 can change its release and latched position over to like this.Axle 74,76 best and lining 64 monoblock casts, but also can both be coupled together with welding or alternate manner.
A pair of elastic pressuring clamping device 78 is from being limited to the socket 80 protruding (seeing Figure 16-19) in the peripheral wall 70.This hold down gag is preferably arranged (seeing Figure 11) with about 160 a ° angle beta space; But also can adopt other interval mode.Each hold down gag 78 comprises the rigid metal tip 84 (seeing Figure 16-19) of outwards moving just like the elastic body 82 of silicon rubber and, and elastic body 82 is packed into, and socket is after 80s to be subjected to the lining protection.Most advanced and sophisticated 84 are attached on the elastic body 82.Most advanced and sophisticated 84 end comprises pair of end walls 86, and this end wall 86 is tapered to form a tapered end.
The invention provides an opening 90 that extends through wear-resisting cover 10 to be used for accepting locking device 40 (seeing Fig. 2,4-7 and 16-20).In optimum structure, opening 90 just in time is formed at the front of back joint 38, thereby makes the front surface of joint 38 define a bearing surface 92.A vertical hole 94 extends through joint 38 and is used to receive rear axle 76 (seeing Fig. 2 and 4-7).Front axle 74 is accommodated in the groove 93 with the steady lock device.Pair of guide rails 96 arranges that along the both sides of opening 90 its direction is identical with the direction in hole 94 substantially.In optimum structure, the sidewall 98 of the opening 90 adjacent with installation surface 16 defines a groove 95, is used to receive the protrusion 99 that the periphery of bearing surface 66 forms before the edge, correctly is installed in the hole 94 (seeing Figure 15) to guarantee long rear axle 76.These can also make equal length, install on arbitrary orientation in two orientation with permission.
In use, rear axle 76 at first is inserted in the hole 94, and makes straight line peripheral wall 72 towards opening 90, and this moment, it was in lock position (referring to Figure 18).Rotation lock device 40 (is seen Figure 16) so that lining 64 is placed in the opening 90 before being placed on wear-resisting cover on the wear surface 29.This moment, locking device 40 is positioned at its off-position, and wherein lining 64 is positioned at opening 90, and flat peripheral wall 72 is inwardly towards wear surface 29.Lining 64 must place on the installation surface 16, could allow joint 38 to insert in the groove 44 like this.Tip 84 at off-position hold down gag 78 engages with the sidewall 98 of opening 90.Shown in Figure 16-19, preferably each other with one about 40 ° angle θ relative tilt, this angle can change in 0 °-90 ° scope sidewall 98.
When being placed on wear-resisting cover 10 on the wear surface 29, opening 90 is aimed at the extension of groove 44 is anterior basically.For wear-resisting 10 weeks of cover are decided to wear surface 29, need rotation lock device 40 (seeing Figure 17) to its latched position (seeing Figure 18 and 20).Interior with the groove 73 that an elongate tool (for example, a screwdriver or pin) is inserted on the arcuate perimeter wall 70 to rotate linings 64 around an axis 101 that limits by axle 74,76.When the wall 98 of hold down gag 78 by opening 90, clamp-oned in succession in the socket 80.At latched position (seeing Figure 18), lining 64 is positioned so that flat peripheral wall 72 outwards leaves wear surface 29 and hold down gag 80 is leaned against on the guide rail 96.The load-bearing surface 102 of guide rail 96 preferably is tilted in relation to each other with about 90 a ° angle φ so that can lean against ordinatedly on the end wall 86 at tip 84.The angle φ of load-bearing surface 102 can change in 60 °-180 ° scope.When angle is in 120 ° of-180 ° of scopes and hold down gag 80 contacted will be the edge of a guide rail 96.In addition, guide rail can be by cancel all, and hold down gag 80 will lean against on the installation surface 16 like this, but does the effective wearing and tearing thickness that will decrease in wear-resisting cover like this.One or more hold down gags can also with a retainer (not shown), contact as a groove, be used for replacing guide rail that locking device is remained on latched position.As long as retainer can prevent the rotation of locking device on both direction releasedly, can only use a hold down gag.
In latched position, the back load-bearing surface 68 of locking device 40 is relative with the load-bearing surface 92 of wear-resisting cover 10, and preceding load-bearing surface 66 is relative with the preceding bearing wall 103 of the front of the groove 44 of coupling apparatus 28.After adopting this structure, the rigid liner 64 of locking device 40 has prevented that wear-resisting cover from vertically moving along wear surface 29.Like this, joint 36,38 just can not thrown off from groove 42,44, and then independently wear-resisting cover 10 is fixed on the wear surface 29.Hold down gag 80 can remain on its locking device with lining 64 releasedly with engaging of guide rail 96.In view of the load-bearing surface 66,68 of axial load by lining 64 bears, so hold down gag can not place a position of bearing these load.
Flat peripheral wall 72 is preferably near on the position of each end and comprises a pair of recess 105, so that locking device 40 is turned to its off-position.Particularly, with an elongated instrument (for example, one screwdriver or pin) engage with a recess 105, when hold down gag 80 adjoining lands lean against in the guide rail 96 one when going up, push or promote the biasing force that this instrument overcomes hold down gag 80 and rotate linings 64 around axle 74,76.Because locking device only needs to overcome the adhesion that exists between locking device and the particle, and does not need to overcome the particle bond strength of particle self, so even also can relatively easily realize the rotation of lining 64 under the situation of particle compacting.The rotation of lining is carried out arriving the off-position up to it continuously.This moment, just can reach the wear-resisting cover 10 that moves up forward so that it is dismantled from wear surface 29.
