Description

Technical Field

[0001] The invention discloses an anti-jamming stability driving wheel mounting structure, belonging to the technical field of crawler accessories. Background Art

[0002] The crawler drive wheel acts as a driving wheel, which is fixed to the travel motor and transmits the driving force of the travel motor to the chain of the crawler through the gear structure, thereby driving the crawler to move.

[0003] Crawler tracks are often used in construction vehicles such as excavators and bulldozers, so the environment in which they are used is usually relatively harsh, with mud and gravel often on the ground. However, existing ordinary drive wheels are often single gear-like structures, so mud, sand and gravel on the ground can easily enter the tooth grooves of the drive wheel and be carried to the chain. And because the ground is uneven, the crawler tracks will continue to vibrate when moving. At this time, the gravel and sand brought up by the drive wheel may bounce due to the vibration and may enter the chain. If the gravel is large, it may cause the chain to become stuck or directly stuck, which will not only reduce stability but also shorten the life of the chain.

[0004] The existing patent application number CN201710065250.7 describes an anti-winding crawler drive wheel. This uses a block to block the drive wheel's tooth grooves, thereby preventing wire entanglement and also preventing the drive wheel from picking up sand and gravel. However, the structure of the drive wheel and the installation method of the block and other components require custom manufacturing, which cannot meet the requirements of ordinary tooth structures for drive wheels directly applied in reality. Therefore, it is not well adapted to various types of current engineering vehicles. Therefore, in order to solve this problem, a new solution is needed. Summary of the Invention

[0005] The purpose of the present invention is to provide an anti-stuck stability driving wheel mounting structure in order to solve the above-mentioned problems.

[0006] The present invention achieves the above-mentioned purpose through the following technical solutions: an anti-jamming stability drive wheel mounting structure, comprising a drive wheel body, a plurality of mounting plates arranged on the drive wheel body, the mounting plates surrounding the drive wheel body and symmetrically arranged on both sides of the drive wheel body, and fixed to the drive wheel body by first bolts and nuts, the mounting plates corresponding to the tooth grooves of the drive wheel body, a stone baffle is hinged on the side of the mounting plate close to the tooth groove, the stone baffle is fitted with the outer contour of the tooth groove, the symmetrical stone baffle blocks the tooth groove, a pushing member is provided on the mounting plate for keeping the stone baffle fitted with the tooth groove, and a pulling component for driving each other is provided between adjacent mounting plates.

[0007] By adopting the above technical solution, the mounting plate is installed by means of the first bolt and nut, so that the installation can be completed without changing the structure of the driving wheel; and the stone baffle is hinged on the mounting plate, so that the stone baffle can be folded and rotated on the mounting plate; and because the mounting plate is arranged at the tooth groove, the stone baffle fits the outer contour of the tooth groove, so when the stone baffle is folded to the top, the two symmetrical stone baffles will completely block the tooth groove, thereby preventing gravel from entering the tooth groove; and by using the pushing member, the stone baffle can be pushed upward so that it can keep blocking the tooth groove; and when the chain passes by, it will press the stone baffle to fold it outward, thereby ensuring the normal coordinated drive of the driving wheel and the chain; by using the pulling component, when the stone baffle is folded open, the adjacent stone baffles are driven to be pulled, and there is a certain degree of folding, so that the chain can more easily push the stone baffle open to ensure transmission.

[0008] Preferably, the mounting plate fits the side of the driving wheel body, the pushing member is an elastic plate, the elastic plate is arranged at the hinge of the mounting plate and the stone baffle, and is fixed to the mounting plate and the stone baffle respectively by a plurality of second bolts and nuts.

[0009] By adopting the above technical solution, since the mounting plate fits against the side of the driving wheel body, when installing the mounting plate, it is only necessary to align it with the threaded hole on the side of the driving wheel and fit it. When the curved side of the driving wheel body fits against the mounting plate, the position angle of the mounting plate will be automatically corrected, making installation more convenient. The elastic plate is connected to the mounting plate and the stone baffle plate at both ends respectively. Therefore, when the stone baffle plate is folded outward, the elastic plate will also bend. After the folding force of the stone baffle plate disappears, the elastic plate will elastically reset and push the stone baffle plate to reset it and cover the tooth groove. Since the elastic plate is installed by the second bolt and nut, there is no need to modify the driving wheel body, and after it is elastically fatigued, it is also convenient to disassemble and replace it.

[0010] Preferably, the pulling assembly includes a mounting rod, a rotating block and a telescopic assembly. The mounting rod is arranged on the outside of the stone baffle and is fixed to the stone baffle by a third bolt and nut. The rotating block is arranged on both ends of the mounting rod and is rotatably connected to the mounting rod through a bearing. The two ends of the telescopic assembly are respectively connected to adjacent rotating blocks.

[0011] By adopting the above technical solution, the mounting rod is fixed to the stone baffle with the third bolt and nut, which makes the installation convenient and stable without changing its structure; and the bearing is used to enable the rotating block to rotate on both ends of the mounting rod; the comfort component connects the two adjacent rotating blocks, so when the stone baffle is folded outward, the telescopic component will pull the adjacent stone baffle to fold outward to a certain angle, and the telescopic performance of the telescopic rod can compensate for the distance between adjacent stone baffles when they are folded to different positions, and the rotating block can cause the telescopic rod to rotate to a certain extent when the stone baffle is folded, thereby preventing the stone baffle from being unable to fold and rotate due to the setting of the telescopic rod.

[0012] Preferably, the telescopic assembly includes a telescopic rod and two ball head blocks, both ends of the telescopic rod are provided with a bump, the ball head block is arranged in the bump and spherically connected to the bump, and the ball head block is fixed to the rotating block by a fourth bolt and nut.

[0013] By adopting the above technical solution, the purpose of telescopic compensation can be achieved by using the telescopic rod, and the ball head connection between the ball head block and the protrusion can increase the freedom of the telescopic rod, so that it can also perform a certain degree of rotation adjustment, thereby better preventing the stone baffle from being stuck during the folding process; and the ball head block is connected to the rotating block by the fourth bolt and nut, so it is only necessary to open a threaded hole on the rotating block, without making any other structural changes, and the installation is convenient and stable.

[0014] Preferably, both ends of the stone baffle are provided with push guide angles for chain pushing, and the edge of the stone baffle is provided with guide protrusions for increasing the contact area with the chain, and the guide protrusions are inclined inwards.

[0015] By adopting the above technical solution, the pushing guide angle is utilized so that after the chain contacts the stone baffle that has been turned open at a certain angle, it will press the pushing guide angle, thereby pushing the stone baffle outward along the pushing guide angle, thereby ensuring that the driving wheel can drive the chain, thereby driving the crawler; and by utilizing the guide protrusion, the contact area between the chain and the pushing guide angle can be increased, thereby better pushing the stone baffle, and the guide protrusion is inclined inward, so that the chain can push the stone baffle open more easily.

[0016] Preferably, the driving wheel body is provided with a shielding assembly for shielding the gap formed by the pushing guide angle, and the shielding assembly includes a mounting seat and two shielding blocks. The mounting seat is arranged at the top of the teeth of the driving wheel body and is fixed to the teeth of the driving wheel body by a fifth bolt and nut. The width of the mounting seat is equal to the width of the top of the teeth of the driving wheel body, and the shielding blocks are hinged to both ends of the mounting seat.

[0017] By adopting the above technical solution, the gap formed between the push guide and the tooth groove can be blocked by the shielding component, thereby preventing gravel from entering the tooth groove from the gap; and the mounting seat that is installed by the fifth bolt and nut only needs to open a threaded hole on the top of the tooth of the driving wheel, and there is no need to change its structure, so the installation is convenient and stable; while the shielding block blocks the gap, it is hinged to the mounting seat, so when the chain contacts it, it will press it and fold it outward, which will not block the chain, so the shielding block has almost no effect on the drive of the chain; and because the width of the mounting seat is equal to the width of the top of the tooth of the driving wheel body, the shielding block will not fold inward, thereby better blocking gravel.

[0018] Preferably, a torsion spring is provided at the hinge between the mounting seat and the shielding block for enabling the shielding block to keep shielding the gap.

[0019] By adopting the above technical solution, the torsion spring can be used to press the blocking block so that it can remain in the state of blocking the gap when there is no external force, thereby ensuring its blocking of gravel and more effectively preventing gravel from entering the tooth groove through the gap.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. Compared with the existing ordinary drive wheel, the present application can block the tooth groove of the drive wheel when the teeth of the drive wheel are not in contact with the chain, thereby preventing mud, sand and gravel on the ground from entering the tooth groove, thereby avoiding damage or jamming of the chain caused by gravel being brought onto the chain, and increasing the service life of the chain.

[0022] 2. Compared to existing improved technologies, this application can block gravel by simply creating threaded holes in ordinary drive wheels without changing their structure. Therefore, the mounting structure of this application can be directly adapted to the tracks of most existing engineering vehicles without the need for special customization of the drive wheels, thus having wide applicability. Furthermore, the bolt and nut connection method is easy to assemble and disassemble, and the connection is secure. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0033] like Figure 1As shown, an anti-jamming stability drive wheel mounting structure includes a drive wheel body 1, which is mounted on a reducer, and the reducer is connected to a travel motor. When the travel motor is started, the reducer is driven to work, reducing the speed and transmitting it to the drive wheel body 1, so that the drive wheel body 1 rotates, and the teeth on the drive wheel body 1 abut against the chain belt of the crawler, thereby driving the chain belt to move, and under the action of the sprocket, guide wheel and supporting wheel, finally driving the crawler to move.

[0034] like Figure 2 As shown, the drive wheel body 1 is provided with several mounting plates 2, which are arranged around the drive wheel body 1 and symmetrically on both sides of the drive wheel body 1. These mounting plates 2 are secured by first bolts and nuts 3 that engage threaded holes in the drive wheel body 1, and the mounting plates 2 can fit tightly against the sides of the drive wheel body 1. Therefore, when assembling the mounting plates 2, one only needs to first align the holes in the mounting plates 2 with the threaded holes in the drive wheel body 1, attach the mounting plates 2 to the drive wheel body 1, and finally, install the first bolts and nuts 3 in the holes and threaded holes and tighten them. Because the mounting plates 2 fit tightly against the curved sides of the drive wheel body 1, they automatically align when the user attaches them to the drive wheel body 1. Only the holes need to be aligned, and no specific angle adjustment is required. This makes installation very simple and stable.

[0035] like Figure 4 As shown, the threaded hole on the driving wheel body 1 is located below the tooth groove, so the mounting plate 2 is arranged corresponding to the tooth groove position of the driving wheel body 1.

[0036] like Figure 2 As shown, a stone baffle 4 is hinged on the side of the mounting plate 2 close to the tooth groove, and the stone baffle 4 fits the outer contour of the tooth groove. A single stone baffle 4 can cover half of a single tooth groove, so the stone baffles 4 symmetrically arranged at both ends of a single tooth groove can completely cover the tooth groove. Because the stone baffle 4 is hinged on the mounting plate 2, it can be folded inward or outward. When it is folded outward, the tooth groove will be exposed, so that it can be driven normally with the chain. When it is folded inward, the tooth groove will be blocked, thereby preventing gravel and sand on the ground from entering the tooth groove, avoiding the chain from being damaged or stuck by the gravel brought up.

[0037] like Figure 2 、 Figure 5As shown, a pusher 5 is provided on the mounting plate 2, and the pusher 5 is an elastic plate 7. It is provided on the outside of the hinge between the mounting plate 2 and the stone baffle 4, and is fixed to the mounting plate 2 and the stone baffle 4 respectively by four second bolts and nuts 8. The elastic plate 7 can press the stone baffle 4 so that the stone baffle 4 will remain folded inward in the absence of external force. When installing the elastic plate 7, it is only necessary to align the two holes on the upper end of the elastic plate 7 with the two holes on the stone baffle 4, align the two holes on the lower end of the elastic plate 7 with the two holes on the top of the mounting plate 2, and then align the four second bolts and nuts 8 with the four holes to install and lock them. The installation is also very simple and sturdy, and when the elastic plate 7 is elastically fatigued, it is also very easy to disassemble and replace it. The elastic plate 7 is made of beryllium copper alloy, which has a strength limit of up to 1250-1500 MPa, and also has very high hardness, elastic limit, fatigue limit and wear resistance. Therefore, in addition to its high elastic limit, it can press the stone baffle 4 so that it can be reset after folding. It also has a longer service life, requires less frequent replacement, and does not generate sparks when impacted, thus ensuring driving safety and the safety of the track.

[0038] like Figure 2 、 Figure 5 、 Figure 6 As shown, a pull assembly 6 is positioned between adjacent mounting plates 2. It comprises a mounting rod 9, a rotating block 10, and a telescoping assembly. The mounting rod 9 is positioned outside the stone guard plate 4 and secured to the stone guard plate 4 via a third bolt and nut 11, making assembly of the mounting rod 9 simple and secure. Two rotating blocks 10 are provided, one at each end of the mounting rod 9 and rotatably connected to the mounting rod 9 via bearings. Thus, the rotating blocks 10 can rotate axially on both ends of the mounting rod 9.

[0039] like Figure 2 、 Figure 7As shown, the telescopic assembly is connected to two adjacent rotating blocks 10 at each end and comprises a telescopic rod 12 and two ball-end blocks 13. The telescopic rod 12 is made of an aluminum alloy, offering greater strength and the ability to withstand greater pressure and tension. Each end of the telescopic rod 12 is provided with a bump 14, and the ball-end blocks 13 are positioned within and spherically connected to the bumps 14. This provides the telescopic rod 12 with a certain degree of rotational freedom, further preventing it from getting stuck. The ball-end blocks 13 are secured to the rotating blocks 10 by fourth bolts and nuts 15. Therefore, when the stone baffle 4 folds outward, the telescopic rod 12 is pulled along with the movement of the rotating blocks 10. After extending to its maximum length, it pulls the rotating block 10 connected at its other end, thereby moving the other stone baffle 4. As the stone baffle 4 folds, the distance between adjacent rotating blocks 10 decreases. The telescopic effect of the telescopic rod 12 compensates for this distance, ensuring that the stone baffle 4 can be moved without getting stuck. Since the folding action of the stone baffle 4 is rotation, if the ends of the telescopic rod 12 are directly fixed to the mounting rod 9, they will become stuck due to the eversion of the connection point when folding. Therefore, the rotating block 10 can prevent it from getting stuck, so that the ends of the telescopic rod 12 can always remain parallel while driving the adjacent stone baffle 4 to fold.

[0040] like Figure 3 As shown, when installing the chain, half of the stone baffle 4 can be manually folded open first, so that the chain plate of the chain can abut against the inner wall of the stone baffle 4 and be accommodated in the space formed after the stone baffle 4 is folded, and the sleeve of the chain can be embedded in the tooth groove of the driving wheel body 1 and abut against the teeth. At this time, after starting the travel motor, the driving wheel body 1 rotates, and the stone baffle 4 that has been folded 90 degrees will, under the influence of the pulling component 6, pull the next adjacent stone baffle 4 to a position of approximately 45 degrees. Therefore, when the chain plate of the chain contacts the next stone baffle 4, it will press it and push it outward to fold 90 degrees. The next stone baffle 4 will be pulled to 45 degrees, and this cycle will continue, so that the stone baffle 4 close to the chain will be opened, thereby not hindering the normal drive of the driving wheel body 1. When the stone baffle 4 is separated from the chain, it will be pressed back to its original position under the elastic action of the elastic plate 7, so as to keep the tooth groove of the driving wheel body 1 blocked and prevent the gravel from entering and being driven upward.

[0041] like Figure 5 、 Figure 6As shown, the stone baffle 4 is provided with a push guide angle 16 at both ends. When the chain link contacts the stone baffle 4, it will first contact and press the push guide angle 16. Because the guide angle is inclined, the stone baffle 4 will be pressed outward and folded after being pressed by the chain link. The stone baffle 4 is also provided with a guide protrusion 17 on the edge. The guide protrusion 17 is inclined inward to increase the contact area with the chain link, making it easier for the stone baffle 4 to be pressed and folded. In addition, a shock-absorbing layer is provided on the outside of the guide protrusion 17 and on the edge of the stone baffle 4 to cushion the force of the stone baffle 4 colliding with each other and the force of the stone baffle 4 colliding with the drive wheel body 1 when the stone baffle 4 is rebounded by the elastic plate 7.

[0042] like Figure 2 、 Figure 8 As shown, due to the setting of the push guide angle 16, when the stone retaining plate 4 is folded inward and blocks the tooth groove, a triangular gap will be formed on both sides of the tooth groove, so there is a risk of gravel entering. A shielding assembly 18 is provided on the driving wheel body 1, which includes a mounting seat 19 and two shielding blocks 20. The mounting seat 19 is set at the top of the teeth of the driving wheel body 1 and is fixed to the teeth of the driving wheel body 1 by the fifth bolt and nut 21. Therefore, it is only necessary to open a threaded hole at the top of each tooth of the driving wheel body 1, without changing its structure, and the installation is also simple and firm. The two shielding blocks 20 are hinged to the two ends of the mounting seat 19, so the two shielding blocks 20 can be folded on the mounting seat 19, and the shape of the shielding blocks 20 can just block the gap, thereby preventing gravel from entering the tooth groove from the gap. The width of the mounting seat 19 is equal to the width of the top of the teeth of the drive wheel body 1. Therefore, the blocking block 20 hinged thereto can only fold outwards; folding inwards will be blocked by the teeth. This prevents the blocking block 20 from being squeezed by gravel and folding inwards, further preventing gravel from entering the tooth groove. A torsion spring 22 is provided at the hinge between the mounting seat 19 and the blocking block 20. Under the action of the torsion spring 22, the blocking block 20 will maintain the force of folding inwards, thereby ensuring that the gap is blocked. When the sleeve of the chain enters the tooth groove, it will not contact the blocking block 20. When the sleeve leaves the tooth groove, it will push the blocking block 20 outwards, allowing it to smoothly leave the tooth groove. Therefore, the blocking block 20 has almost no effect on the transmission between the drive wheel body 1 and the chain.

[0043] The present application prevents the driving wheel from picking up gravel during operation without changing the structure of the existing driving wheel itself. Therefore, the present application can be adapted to various existing tracked engineering vehicles, has high applicability, and is suitable for promotion.

[0044] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein.

The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
