Technical Field
[0001] The utility model relates to the technical field of vehicles, in particular to a limit block bracket and a mining dump truck. Background Art
[0002] At present, mining dump trucks generally work in open-pit mines with harsh road conditions. The axle will bounce up and down during driving. If the axle bounces too much, it will cause impact damage to other parts. Therefore, limit blocks are usually installed on the axle and placed under the frame to limit the bounce of the axle within a certain range, thereby playing a limiting role. In order to facilitate the disassembly and replacement of the limit block and ensure the appropriate limit range of the bounce, a limit block bracket is also installed.
[0003] However, the current limit block bracket has low structural strength and poor reliability. Due to the poor road conditions in mining areas and bumpy roads, it is easy to deform or break during transportation by mining dump trucks, which may cause the limit blocks installed on the top to wear the tires. In severe cases, it may even scratch the tires, causing losses and possible safety accidents. Utility Model Content

[0038] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0039] Example:
[0040] like Figures 1 to 3As shown, an embodiment of the present application discloses a limit block bracket, which is used to be installed on a leaf spring seat and support the limit block assembly. The limit block bracket is an integrally formed part, and the specific structure includes: a bottom plate 1, two support plates 2, a top plate 3 and a reinforcement plate 4.
[0041] It should be noted that if Figure 4 As shown, the limit block is a rectangular structure with a mounting plate at the bottom, and circular mounting holes are opened on the mounting plate on the left and right sides of the limit block. In addition, the limit block is made of polyurethane rubber, which can buffer the impact on the frame when the middle and rear axles jump up.
[0042] The top surface of the bottom plate 1 is provided with first through holes 11 at both the front and rear sides. The first through holes 11 are circular holes for allowing the screw rods of the bolts to pass through, thereby achieving bolt connection with the leaf spring seat.
[0043] The two support plates 2 are respectively arranged vertically on the left and right sides of the top surface of the bottom plate 1; the two support plates 2 are located directly below the left and right sides of the bottom of the limiting block, thereby providing stable support thereto.
[0044] The top plate 3 is arranged on the top surfaces of the two support plates 2, and second through holes 31 are opened on the left and right sides of the top surface of the top plate 3; the shape, size and opening position of the second through holes 31 correspond one-to-one to the mounting holes on the limit block, and are used to realize the bolt connection between the limit block and the top plate 3; in addition, the shape and size of the top plate 3 correspond to the mounting plate on the limit block, thereby playing a positioning role and improving the disassembly and assembly efficiency and regularity.
[0045] The reinforcing plate 4 is arranged between the two supporting plates 2, and is connected to the top plate 3 and the bottom plate 1 on the upper and lower sides respectively; the reinforcing plate 4 is arranged vertically, so that it can provide stable support for the limit block, improve the structural strength and enhance the bearing capacity; in addition, it is also connected to other plates, thereby significantly improving the structural stability of the bracket and having strong impact resistance.
[0046] During installation, the limit block bracket is arranged on the boss on the side of the leaf spring seat, and the first through hole 11 is made to correspond to the threaded hole on the boss one by one, and then the bolt is vertically rotated from the top of the bottom plate 1 and inserted into the first through hole 11 and the threaded hole, thereby realizing the bolt connection between the bottom plate 1 and the boss, thereby completing the installation of the limit block bracket. The mounting plate at the bottom of the limit block is kept in contact with and aligned with the top plate 3, so that the second through hole 31 corresponds to the mounting hole on the limit block one by one, and then the bolt is vertically passed through the second through hole 31 and the mounting hole from the top plate 3 and then tightened with the nut, thereby realizing the bolt connection between the bottom plate 1 and the boss, thereby completing the installation of the limit block.
[0047] Through the above-mentioned design of the limit block bracket, the structural strength is improved and the bearing capacity is enhanced; the panels are tightly combined and the structure is stable; the overall structure is compact and regular, which is convenient for installation and layout; the structure is simple and convenient for production and manufacturing.
[0048] In some embodiments, Figure 2 As shown, the bottom plate 1 and the top plate 3 are rectangular structures and are concentrically arranged; the axes of the bottom plate 1 and the top plate 3 along the length direction are perpendicular to each other.
[0049] Specifically, the above-mentioned arrangement enables the limit block to be arranged concentrically with the bottom plate 1 and the top plate 3 after installation, thereby ensuring the unity of the center of gravity, making the overall force uniform, and improving the regularity and bearing capacity.
[0050] For example, Figure 1 As shown, the corners of the bottom plate 1 and the top plate 3 are both provided with arc chamfers. The arc chamfers are preferably a quarter of a circle, with a smooth transition and good use effect.
[0051] The above-mentioned setting can avoid sharp protrusions at corners, reduce the risk of injury to people or objects by sharp edges, and thus reduce the possibility of accidental scratches or cuts during operation or use, thereby improving safety; in addition, it also reduces stress concentration at sharp points, thereby reducing the risk of material cracks or fractures, and helps to improve the strength and durability of the structure.
[0052] Based on the above scheme, if Figure 3 As shown, the support plate 2 is in an isosceles trapezoidal structure, and the length of the upper bottom surface is shorter than the length of the lower bottom surface.
[0053] The above arrangement can effectively bear the load and distribute it on the base plate 1 to ensure the stability and safety of the structure; it also provides additional support points and rigid connections to effectively resist the effects of external forces, reduce deformation and tilt of the structure, and help maintain the stability and integrity of the structure; and ensure that the load is evenly distributed and avoid problems caused by excessive or uneven local bearing capacity of the base plate 1.
[0054] In this embodiment, if Figure 2 As shown, the two support plates 2 are parallel to each other and are symmetrically arranged about the axis of the bottom plate 1 along the length direction.
[0055] The above arrangement enables the top plate 3 to be subjected to uniform force in the width direction, so that the load is evenly distributed, thereby reducing stress concentration and improving the stability and integrity of the structure.
[0056] In this embodiment, if Figure 3 As shown, in order to improve the compactness of the structure, the length of the bottom surface of the support plate 2 is equal to the width of the top plate 3.
[0057] Under the premise of ensuring that the support plate 2 can fully support the top plate 3, the above arrangement reduces the production materials, improves the compactness of the structure and the overall regularity, and has a good use effect.
[0058] In this embodiment, if Figure 2 As shown, there are four second through holes 31 , which are respectively disposed at four corners of the top plate 3 and are centrally symmetrically distributed about the center point of the top plate 3 .
[0059] The above arrangement ensures the stability of the connection and makes the top plate 3 evenly stressed, so that the load is evenly distributed, thereby reducing stress concentration and improving the stability and integrity of the structure.
[0060] In this embodiment, if Figure 2 As shown, arc grooves 32 are formed on the front and rear sides of the top plate 3 . The arc grooves 32 are concentric with the first through hole 11 , and the diameter of the arc grooves 32 is greater than the diameter of the first through hole 11 .
[0061] When disassembling and assembling the bolt, the electric socket wrench is vertically passed through the arc groove 32 to be sleeved on the bolt head, and then the bolt can be driven to loosen or tighten, thereby completing the disassembly and assembly of the limit block.
[0062] The arc groove 32 can be provided to avoid the use of the socket wrench, so that the first through hole 11 can be arranged closer to the middle of the bottom plate 1, thereby shortening the length of the bottom plate 1, improving the compactness of the structure and reducing the amount of material used.
[0063] In this embodiment, if Figure 1 As shown, the reinforcing plate 4 is of a rectangular structure and is in the same vertical plane as the axis of the bottom plate 1 along the width direction.
[0064] Specifically, the reinforcing plate 4 of the rectangular structure can be fully connected with other plates, thereby improving the stability of the structure; if it is arranged on the axis along the width direction of the base plate 1, it can be located exactly in the middle of its bottom after the limit block is installed, thereby improving the uniformity of force and making the load evenly distributed, thereby reducing stress concentration and improving the stability and integrity of the structure.
[0065] The embodiment of the present application also discloses a mining dump truck, comprising the above-mentioned limit block bracket.
