Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, specifically to a ripper support and a bulldozer. Background Technology

[0002] In related technologies, bulldozer rippers typically include a ripper support and ripping teeth. The ripper support is used to support and fix the ripping teeth. The working environment of bulldozer rippers is relatively harsh. During ripping operations, the ripper support bears and transmits large impact loads, including impact force and cutting force. The crossbeam of the ripper support has a relatively thin structure and poor fatigue resistance. Under the action of alternating stress during long-term operation, the support may experience failure problems such as twisting, deformation or weld cracking, which affects the service life of the ripper support. Utility Model Content

[0003] This invention provides a ripper support and a bulldozer to solve the problems of low structural strength and poor fatigue resistance of existing ripper supports.

[0004] In a first aspect, this utility model provides a soil ripper support, comprising: a crossbeam, the crossbeam having a first cavity and a toothed hole, the toothed hole penetrating the crossbeam along a first direction, the first cavity communicating with the toothed hole, the first direction being perpendicular to the length direction of the crossbeam; and a support assembly, the support assembly being disposed within the first cavity, the support assembly including two support members and a connector, the two support members being respectively disposed on opposite sides of the toothed hole along the length direction of the crossbeam, and in a second direction perpendicular to both the first direction and the length direction, at least one side of the toothed hole having the connector, the connector being connected between the support member and the crossbeam.

[0005] Beneficial effects: Each support component enhances the local strength of the crossbeam. Connecting two supports via connectors allows the crossbeam to transmit force along its length through both supports and the connector. This not only improves the crossbeam's bending and torsional stiffness but also results in a more uniform stress distribution, strengthening its ability to withstand alternating loads generated by the ripper. This reduces the risk of plastic deformation in the ripper support. Because of the lower deformation risk, the stress in the weld area is significantly reduced, decreasing the risk of weld cracking and improving the stability of the ripper support under high-intensity, complex conditions. This also lowers the failure rate and extends the service life of the ripper support. Furthermore, the ripping teeth can pass between the two supports, and the connector is located between the supports and the crossbeam. Therefore, the ripping teeth do not interfere with the connector when passing through the tooth holes, balancing the reinforcement effect of the support components on the crossbeam with the ease of installation of the ripping teeth.

[0006] In one optional embodiment, the support member includes: a support plate, the outer peripheral surface of which is connected to the inner peripheral surface of the crossbeam, and the connector is connected to the support plate; and a first reinforcing plate, the first reinforcing plate being connected to the side of the support plate facing away from the toothed hole, and the first reinforcing plate being connected to the inner peripheral surface of the crossbeam.

[0007] Beneficial effects: It can increase the connection area between the support and the crossbeam, and the connection area between the support plate and the crossbeam extends along the circumference of the crossbeam, while the connection area between the first reinforcing plate and the crossbeam extends along the length of the crossbeam. The support plate and the first reinforcing plate can support each other and transmit force, which is beneficial to improving the load-bearing capacity of the support and strengthening the bending stiffness and torsional stiffness of the crossbeam from different directions.

[0008] In one alternative embodiment, the support plate and the connector are welded together and have a first weld mark, and the support plate has a first welding groove on the side facing the toothed hole, with the first weld mark located in the first welding groove.

[0009] Beneficial effects: By using the first welding groove to accommodate the first weld mark, interference between the first weld mark and the loosening tooth can be avoided, which facilitates the installation of the loosening tooth while ensuring structural stability.

[0010] In one optional embodiment, a second weld mark is provided between the support plate and the connector, the support plate has a second welding groove on the side facing the first reinforcing plate, the second weld mark is located in the second welding groove, and the connector is connected to the first reinforcing plate.

[0011] Beneficial effects: By setting the second weld mark, the support plate and the connector can be welded on opposite sides of the support plate, which improves the connection strength between the support plate and the connector. Furthermore, by using the second welding groove to accommodate the second weld mark, interference between the second weld mark and the first reinforcing plate can be avoided.

[0012] In one alternative embodiment, the support member includes a plurality of first reinforcing plates, which are spaced apart circumferentially along the support plate.

[0013] Beneficial effects: The connection area between the support and the crossbeam is larger, and the force transmission path between the support plate and the crossbeam is also increased, which helps to improve the support effect of the support on the crossbeam.

[0014] In one alternative embodiment, the ripper bracket further includes a seal, the first cavity extending through both ends of the crossbeam along its length, the seal being connected to the crossbeam and sealing the opening of the first cavity.

[0015] Beneficial effects: The support assembly can be installed into the first cavity from the end opening, improving the ease of assembly between the support assembly and the crossbeam. After the support assembly and the crossbeam are assembled, the seal is connected to the crossbeam to seal the opening of the first cavity, preventing rainwater, leaves, mud, and other impurities from entering the first cavity, improving the cleanliness of the first cavity, reducing the rate of oxidation and corrosion of the crossbeam and support assembly, and preventing the end of the crossbeam from being scratched or bumped by foreign objects.

[0016] In one alternative embodiment, the support assembly includes two connectors, which are disposed on opposite sides of the toothed hole in the second direction.

[0017] Beneficial effects: It can increase the connection strength between the two supports and increase the force transmission path between the two supports, resulting in a more uniform overall force distribution along the length of the beam.

[0018] In one alternative embodiment, the cross-section of the beam is configured as annular.

[0019] Beneficial effects: The uniform and symmetrical crossbeams facilitate stress transfer and reduce weld seams caused by splicing, resulting in higher structural strength.

[0020] In one optional embodiment, the ripper support further includes: a drive arm connected to the crossbeam and adapted to be connected to the drive mechanism of the ripper; a toothed sleeve fitted on the crossbeam and adapted to be connected to ripping teeth; and a vertical plate assembly including a vertical plate having a first surface connected to the drive arm, the toothed sleeve, and the crossbeam.

[0021] Beneficial effects: By connecting the toothed sleeve, drive arm and crossbeam together with the upright plate, the force transmission efficiency between the toothed sleeve, drive arm and crossbeam is increased. The load of the ripping tooth is transferred to the upright plate and crossbeam through the toothed sleeve, and then to the drive arm through the upright plate and crossbeam. The alternating load on the ripper support is further distributed. At the same time, the upright plate assembly increases the overall rigidity of the ripper support, making the ripper support structure more stable and reliable.

[0022] In one alternative embodiment, the upright plate further has a second surface, the first surface and the second surface being located on opposite sides of the upright plate; the upright plate assembly further includes a bent plate and a second reinforcing plate, the bent plate being connected to the second surface, the bent plate being convex in a direction away from the upright plate, a second cavity being formed between the bent plate and the upright plate, the second reinforcing plate being located within the second cavity, and the second reinforcing plate being connected to the bent plate and the upright plate.

[0023] Beneficial effects: The force can be transmitted between the vertical plate and the curved plate through the second reinforcing plate, which increases the force transmission efficiency between the vertical plate and the curved plate. The force on the vertical plate assembly is more uniform, which helps to improve the load capacity of the ripper support, reduce the probability of damage to the ripper support, and extend the service life of the ripper support.

[0024] In one alternative embodiment, the upright plate assembly further includes: a sealing plate, the sealing plate being connected to the curved plate and the upright plate, the sealing plate being located on opposite sides of the second cavity in the length direction of the crossbeam, the sealing plate covering the end of the second cavity; the sealing plate being inclined relative to the crossbeam, and the two sealing plates gradually moving closer together in a direction away from the upright plate.

[0025] Beneficial effects: By sealing the second cavity with sealing plates, rainwater, leaves, dirt, and other impurities are prevented from entering, improving the cleanliness of the second cavity and reducing the rate of oxidation and corrosion of the upright panel assembly. Furthermore, the two sealing plates move closer to each other away from the upright panel. On one hand, the length of the curved plate gradually decreases away from the upright panel, reducing its volume and lowering the probability of it colliding with external objects. On the other hand, the two sealing plates and the curved plate roughly form an isosceles trapezoid, improving the structural stability of the upright panel assembly and helping to reduce the probability of damage and deformation.

[0026] In one alternative embodiment, on the upright plate, the orthographic projection of the curved plate and the orthographic projection of the crossbeam are at least partially overlapped.

[0027] Beneficial effects: The bending plate can increase the bending resistance of the area where the crossbeam is located, thereby reducing the probability of crossbeam deformation and extending the service life of the ripper support.

[0028] In one alternative embodiment, the cross-section of the bent plate is configured as an arc.

[0029] Beneficial effects: The bending plate is subjected to uniform stress in all areas, avoiding stress concentration on the bending plate. Furthermore, the second cavity between the bending plate and the vertical plate can be roughly triangular in structure, which can improve the structural strength of the vertical plate assembly and make the vertical plate assembly more load-bearing.

[0030] Secondly, this utility model also provides a bulldozer, including: a ripper, the ripper including: the above-mentioned ripper support; ripping teeth, the ripping teeth being disposed in the tooth holes.

[0031] Beneficial effects: By utilizing the above-mentioned ripper support, bulldozers can achieve normal soil loosening operations while improving the strength, bending stiffness, and torsional stiffness of the ripper support, extending the service life of the ripper support, and thus extending the service life of the bulldozer.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0037] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0038] The following is combined Figures 1 to 9 The following describes embodiments of the present invention.

[0039] According to an embodiment of this utility model, a bulldozer is provided, which includes a ripper, a ripper support 1, and ripping teeth 2. The ripping teeth 2 are mounted on the ripper support 1, which can be connected to a hydraulic cylinder on the bulldozer. The hydraulic cylinder drives the ripper support 1 to move vertically, so that the ripping teeth 2 can contact or separate from the ground. When the ripping teeth 2 are separated from the ground, the bulldozer can move normally; when the ripping teeth 2 are in contact with the ground, the ripping teeth 2 can loosen the soil on the ground.

[0040] First, let’s introduce the ripper support 1 according to an embodiment of the present invention. The ripper support 1 includes a crossbeam 100 and a support assembly 200.

[0041] The crossbeam 100 has a first cavity 101 and a toothed hole 102. The toothed hole 102 penetrates the crossbeam 100 along a first direction. The first cavity 101 communicates with the toothed hole 102. The first direction is perpendicular to the length direction of the crossbeam 100. The loosening teeth 2 pass through the toothed hole 102. A support assembly 200 is disposed in the first cavity 101. The support assembly 200 includes two support members 210 and a connector 220. The two support members 210 are respectively disposed on opposite sides of the toothed hole 102 along the length direction of the crossbeam 100. In a second direction perpendicular to both the first direction and the length direction, at least one side of the toothed hole is provided with a connector 220. The connector 220 connects the support members 210 and the crossbeam 100. Both support members 210 are connected to the connector 220. On a projection plane perpendicular to the first direction, the orthographic projection of the connector 220 is located outside the orthographic projection of the toothed hole 102, or the edge of the orthographic projection of the connector 220 contacts the edge of the orthographic projection of the toothed hole 102.

[0042] Specifically, the ripper support 1 also includes a sealing element 230. The first cavity 101 extends through both ends of the crossbeam 100 along its length. The sealing element 230 is connected to the crossbeam 100 and seals the opening of the first cavity 101. The sealing element 230 can be made of an elastic material, such as rubber or silicone. It can be inserted into the crossbeam 100 and can be press-fitted to ensure reliable connection between the sealing element 230 and the crossbeam 100. Alternatively, the sealing element 230 can be made of metal and can be welded, riveted, or bolted to the crossbeam 100.

[0043] By extending the first cavity 101 through both ends of the crossbeam 100 along its length, the support assembly 200 can be installed into the first cavity 101 from its end opening, improving the ease of assembly between the support assembly 200 and the crossbeam 100. After the support assembly 200 and the crossbeam 100 are assembled, the seal 230 is connected to the crossbeam 100 to seal the opening of the first cavity 101, preventing rainwater, leaves, soil, and other impurities from entering the first cavity 101, improving the cleanliness of the first cavity 101, reducing the rate of oxidation and corrosion of the crossbeam 100 and the support assembly 200, and preventing the end of the crossbeam 100 from being scratched or bumped by foreign objects, thus extending the service life of the ripper bracket 1.

[0044] The cross-section of the crossbeam 100 is circular. That is to say, the crossbeam 100 can be constructed as a one-piece, continuous circular tube structure, which has good overall structural strength and rigidity. The toothed holes 102 are opened in the middle area along the length of the crossbeam 100. The crossbeam 100 is uniform and symmetrical, which is conducive to stress transmission and reduces the welds caused by splicing, resulting in higher structural strength.

[0045] In this embodiment of the invention, a support assembly 200 is provided within the first cavity 101 of the crossbeam 100. The support assembly 200 includes two support members 210, which are respectively disposed on opposite sides of the toothed hole 102 along the length of the crossbeam 100. The support members 210 are connected to the crossbeam 100, and each support member 210 can improve the local strength of the crossbeam 100. The two support members 210 are connected by a connector 220, so that the crossbeam 100 can transmit force along its length through the two support members 210 and the connector 220. This not only improves the bending and torsional stiffness of the crossbeam 100, but also makes the stress distribution on the crossbeam 100 more uniform, enhancing the crossbeam 100's ability to resist alternating loads generated by the ripper. This reduces the risk of plastic deformation in the ripper support 1. Because the deformation risk of the ripper support 1 is small, the stress in the weld area on the ripper support 1 is also significantly reduced, reducing the risk of weld cracking. This improves the working stability of the ripper support 1 under high-intensity and complex working conditions, reduces the failure rate of the ripper support 1, and extends the service life of the ripper support 1.

[0046] In addition, the soil loosening tooth 2 can pass between the two support members 210, and the connector 220 is located between the support member 210 and the crossbeam 100. Therefore, the soil loosening tooth 2 will not interfere with the connector 220 when passing through the tooth hole 102, thus taking into account both the reinforcement effect of the support component 200 on the crossbeam 100 and the ease of installation of the soil loosening tooth 2.

[0047] In addition, the support assembly 200 includes two connectors 220, which are respectively disposed on opposite sides of the toothed hole 102 in the second direction. By setting two connectors 220, the connection strength between the two support members 210 can be increased, and the force transmission path between the two support members 210 can be increased. The overall force distribution along the length of the beam 100 is more uniform, which further improves the strength, bending stiffness, and torsional stiffness of the ripper bracket 1, effectively reducing the failure rate of the ripper bracket 1 and extending its service life. Of course, the number of connectors 220 in the support assembly 200 can also be increased according to actual usage requirements.

[0048] The bulldozer of this utility model embodiment utilizes the above-mentioned ripper bracket 1 to achieve normal soil loosening operations while improving the strength, bending stiffness and torsional stiffness of the ripper bracket 1, extending the service life of the ripper bracket 1, and thus extending the service life of the bulldozer.

[0049] In some embodiments, Figure 2 , Figure 4 , Figure 6 and Figure 8As shown, the support member 210 includes a support plate 211 and a first reinforcing plate 212. The outer peripheral surface of the support plate 211 is connected to the inner peripheral surface of the crossbeam 100. The connector 220 is connected to the support plate 211. The first reinforcing plate 212 is connected to the side of the support plate 211 facing away from the toothed hole 102. The first reinforcing plate 212 is connected to the inner peripheral surface of the crossbeam 100.

[0050] For example, the support plate 211, the crossbeam 100, and the connector 220 are first welded into a single structure, and then the support assembly 200 is placed into the first cavity 101 as a whole, and then the support assembly 200 and the crossbeam 100 are welded into a single structure. Furthermore, the first reinforcing plate 212 can extend along the length of the crossbeam 100.

[0051] By setting the support plate 211 and the first reinforcing plate 212, the connection area between the support member 210 and the crossbeam 100 can be increased. The connection area between the support plate 211 and the crossbeam 100 extends along the circumference of the crossbeam 100, and the connection area between the first reinforcing plate 212 and the crossbeam 100 extends along the length of the crossbeam 100. The support plate 211 and the first reinforcing plate 212 can support and transmit force to each other, which is beneficial to improving the load-bearing capacity of the support member 210, strengthening the bending stiffness and torsional stiffness of the crossbeam 100 from different directions, ensuring that the ripper support 1 can work stably under harsh working conditions, reducing the probability of damage to the crossbeam 100, and extending the service life of the crossbeam 100.

[0052] The support member 210 includes multiple first reinforcing plates 212, which are spaced apart circumferentially along the support plate 211. This increases the connection area between the support member 210 and the crossbeam 100, and also increases the force transmission paths between the support plate 211 and the crossbeam 100. This improves the support effect of the support member 210 on the crossbeam 100, thereby increasing the strength, bending stiffness, and torsional stiffness of the crossbeam 100, reducing the probability of deformation of the crossbeam 100, increasing the load-bearing capacity and damage resistance of the ripper bracket 1, expanding its application range, and extending its service life.

[0053] Furthermore, such as Figure 2 , Figure 3 and Figure 8 As shown, the support plate 211 and the connector 220 are welded together and have a first weld mark. The support plate 211 has a first welding groove 213 on the side facing the tooth hole 102, and the first weld mark is located in the first welding groove 213. Welding the support and the connector 220 together makes the connection between the support and the connector 220 convenient and reliable. By using the first welding groove 213 to accommodate the first weld mark, interference between the first weld mark and the loosening tooth 2 can be avoided, which facilitates the installation of the loosening tooth 2 while ensuring structural stability.

[0054] like Figure 2 , Figure 3 and Figure 8 As shown, a second weld mark is present between the support plate 211 and the connector 220. A second welding groove 214 is provided on the side of the support plate 211 facing the first reinforcing plate 212, and the second weld mark is located within the second welding groove 214. The connector 220 is connected to the first reinforcing plate 212. The connector 220 can be connected to one first reinforcing plate 212, or it can be connected to multiple first reinforcing plates 212 simultaneously. Welding can also be performed between the connector 220 and the first reinforcing plates 212.

[0055] By setting a second weld mark, the support plate 211 and the connector 220 can be welded on opposite sides of the support plate 211, thereby improving the connection strength between the support plate 211 and the connector 220. Furthermore, by using the second welding groove 214 to accommodate the second weld mark, interference between the second weld mark and the first reinforcing plate 212 can be avoided, thereby increasing the contact area between the first reinforcing plate 212 and the connector 220. This facilitates the connection between the first reinforcing plate 212 and the connector 220 and also improves the reliability of the connection between the first reinforcing plate 212 and the connector 220.

[0056] In some embodiments, such as Figure 1 and Figure 9 As shown, the ripper support 1 also includes a drive arm 300, a toothed sleeve 500, and a vertical plate assembly 400. The drive arm 300 is connected to the crossbeam 100 and is adapted to be connected to the drive mechanism of the ripper. The toothed sleeve 500 is sleeved on the crossbeam 100 and is adapted to be connected to the ripping teeth 2. The vertical plate assembly 400 includes a vertical plate 410, which has a first surface 411. The first surface 411 is connected to the drive arm 300 and the crossbeam 100.

[0057] For example, the drive arm 300, the toothed sleeve 500, and the crossbeam 100 can all be welded to the vertical plate 410. The drive arm 300 can be rotatably connected to the working cylinder on the bulldozer, using the working cylinder to drive the ripper bracket 1 to move vertically, allowing the ripping teeth 2 to contact or separate from the ground. The ripping teeth 2 can pass through the toothed sleeve 500, which is connected to the toothed sleeve 500 via a pin. The toothed sleeve 500 increases the connection strength between the ripping teeth 2 and the crossbeam 100. Both the drive arm 300 and the toothed sleeve 500 can be welded to the crossbeam 100. There can be two drive arms 300, with the toothed sleeve 500 located between the two drive arms 300, spaced apart.

[0058] By setting up the vertical plate assembly 400, the toothed sleeve 500, the drive arm 300 and the crossbeam 100 are connected together by the vertical plate 410, which increases the force transmission efficiency between the toothed sleeve 500, the drive arm 300 and the crossbeam 100. The load of the ripping tooth 2 is transmitted to the vertical plate 410 and the crossbeam 100 through the toothed sleeve 500, and then to the drive arm 300 through the vertical plate 410 and the crossbeam 100. The alternating load on the ripper support 1 is further dispersed. At the same time, the vertical plate assembly 400 increases the overall rigidity of the ripper support 1, making the structure of the ripper support 1 more stable and reliable.

[0059] In some embodiments, such as Figure 1 and Figure 9 As shown, the upright plate 410 also has a second surface 412, with the first surface 411 and the second surface 412 located on opposite sides of the upright plate 410. The upright plate assembly 400 also includes a bent plate 420 and a second reinforcing plate 430. The bent plate 420 is connected to the second surface 412 and protrudes in a direction away from the upright plate 410. A second cavity 401 is formed between the bent plate 420 and the upright plate 410. The second reinforcing plate 430 is located within the second cavity 401 and is connected to the bent plate 420 and the upright plate 410.

[0060] There can be multiple second reinforcing plates 430, and the multiple second reinforcing plates 430 are spaced apart along the length direction of the crossbeam 100.

[0061] In this way, the force can be transmitted between the upright plate 410 and the curved plate 420 through the second reinforcing plate 430, which increases the force transmission efficiency between the upright plate 410 and the curved plate 420. The upright plate assembly 400 is subjected to more uniform force, which is conducive to improving the load capacity of the ripper support 1, reducing the probability of damage to the ripper support 1, and extending the service life of the ripper support 1.

[0062] Specifically, the curved plate 420 has an arc-shaped cross-section. The curved plate 420 can be integrally bent into shape. The curved plate 420 experiences uniform stress across its various regions, avoiding stress concentration. Furthermore, the second cavity 401 between the curved plate 420 and the vertical plate 410 can be approximately a triangular structure, which improves the structural strength of the vertical plate assembly 400 and enhances its load-bearing capacity.

[0063] Furthermore, such as Figure 1 and Figure 9 As shown, the upright plate assembly 400 also includes a sealing plate 440, which is connected to the curved plate 420 and the upright plate 410. The sealing plate 440 is located on opposite sides of the second cavity 401 along the length of the crossbeam 100, and the sealing plate 440 covers the end of the second cavity 401. The sealing plate 440, the curved plate 420, and the upright plate 410 can be welded together.

[0064] By setting the sealing plate 440 to close the opposite sides of the second cavity 401 along the length of the crossbeam 100, it is not necessary to cover the opposite sides of the second cavity 401 along the length of the crossbeam 100 with the bending plate 420. The bending plate 420 can be bent in only one direction, making its construction convenient and its structural strength high. Furthermore, closing the second cavity 401 can prevent rainwater, leaves, mud, and other impurities from entering the second cavity 401, improving the cleanliness of the second cavity 401, reducing the rate of oxidation and corrosion of the upright panel assembly 400, and preventing the ends of the upright panel assembly 400 from being scratched or bumped by foreign objects, thus extending the service life of the upright panel assembly 400.

[0065] The sealing plates 440 are inclined relative to the crossbeam 100, and the two sealing plates 440 move closer to each other in the direction away from the upright plate 410. In this way, on the one hand, the length of the bent plate 420 gradually decreases in the direction away from the upright plate 410, and the volume of the bent plate 420 is reduced, which can reduce the probability of the bent plate 420 colliding with external objects. On the other hand, the two sealing plates 440 and the bent plate 420 roughly form an isosceles trapezoid, which improves the structural stability of the upright plate assembly 400, helps to reduce the probability of damage and deformation of the upright plate assembly 400, and extends the service life of the upright plate assembly 400.

[0066] In some embodiments, such as Figure 1 As shown, on the upright plate 410, the orthographic projection of the curved plate 420 and the orthographic projection of the crossbeam 100 are at least partially overlapped. Specifically, on the upright plate 410, the orthographic projection of the curved plate 420 can be completely located within the orthographic projection of the crossbeam 100. In this way, the curved plate 420 can increase the bending resistance of the area where the crossbeam 100 is located, thereby reducing the probability of deformation of the crossbeam 100 and extending the service life of the ripper support 1.

[0067] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
