Abstract
Description
Technical Field
[0001] This application relates to the field of engineering machinery technology, specifically to a rotatable outrigger bracket for mining trucks. Background Technology
[0002] Mining vehicles typically use outriggers to stabilize the vehicle body during operation, preventing swaying and ensuring normal operation. At the same time, when the vehicle is stationary, the outriggers help maintain the vehicle's normal posture. However, mining vehicles also need to be able to travel on rough terrain, and the presence of outriggers can limit the vehicle's ability to travel on steep inclines.
[0003] The fixed position of the outrigger structure and the frame in the existing technology cannot be adjusted, which can easily cause the presence of the outrigger to restrict other parts of the frame (such as the fuel tank, cab and engine).
[0004] In addition, due to space constraints, the outriggers are fixed to the vehicle frame, making mining vehicles prone to collisions with large rocks on the ground while driving. They are also easily restricted when climbing slopes, affecting the vehicle's passability.
[0005] Therefore, the leg structure in the existing technology has room for further improvement. Utility Model Content
[0006] In view of this, and addressing the technical problem that the position of the outrigger structure in the prior art cannot be adjusted, making it easy for the outrigger structure of mining trucks to collide with rough ground during operation and restricting its ability to climb slopes, thus reducing the vehicle's passability, this application provides a rotatable outrigger bracket for mining trucks. By setting a rotatable bracket between the frame and the outrigger, the rotatable bracket can drive the outrigger to rotate, allowing the outrigger to rotate to the side closer to the frame when the mining truck is on rough ground, thereby moving it away from the ground. This effectively avoids the restriction on the outrigger when the vehicle is climbing slopes, improves the vehicle's passability, enhances the adaptability of the mining truck to the ground, and improves driving comfort.
[0007] To achieve the above objectives, this application provides the following technical solution: a rotatable outrigger bracket for mining trucks, comprising:
[0008] Frame;
[0009] The support leg is connected to the frame and is used to support the frame.
[0010] A connecting shaft is provided, through which the frame is connected to the support leg. The connecting shaft is located on the side of the frame and is perpendicular to the frame.
[0011] A rotating bracket, which is connected to the support leg, is located between the vehicle frame and the support leg;
[0012] The plane in which the outrigger rotates is perpendicular to the plane in which the frame rotates.
[0013] Compared to existing technologies, this new technology includes a connecting shaft and a rotating bracket. The chassis is connected to the outriggers via the connecting shaft, which is perpendicular to the chassis. The plane in which the outriggers rotate is perpendicular to the plane in which the chassis rotates, allowing the outriggers to rotate relative to the chassis. This allows the outriggers to rotate from a parallel to the ground to a perpendicular to the ground, improving their flexibility. When driving on rough terrain, the rotating function of the outriggers allows them to retract or rotate to a more compact position when not in use, effectively saving space and avoiding the space occupation problems that may be caused by traditional outrigger structures. This enables mining trucks to better adapt to the environment in complex terrain.
[0014] In some embodiments of this application, a locking mechanism is also included, which is connected to the rotating bracket and is used to lock or unlock the rotation state of the rotating bracket;
[0015] The frame is provided with a positioning hole for the locking mechanism to be inserted, and the locking mechanism passes through the rotating bracket and the positioning hole in sequence to connect with the frame.

[0017] There are at least a plurality of locking components, and adjacent locking components are spaced apart.
[0018] Furthermore, the locking mechanism includes a positioning rod and a positioning element. The positioning rod passes through the rotating bracket and the positioning hole in sequence and is connected to the vehicle frame. The positioning element is used to lock or unlock the positioning rod.
[0019] The positioning rod is provided with a locking hole for the positioning member to be inserted, and the locking hole is adapted to the positioning member.
[0020] In some embodiments of this application, a bushing is fitted onto the outer surface of the connecting shaft, and the bushing is located between the rotating bracket and the connecting shaft;
[0021] The bushing has a mounting hole, and an adjusting member is provided in the mounting hole. The adjusting member is used to fix the connection between the bushing and the connecting shaft.
[0022] Furthermore, a copper sleeve is provided between the bushing and the connecting shaft, the copper sleeve being fitted onto the connecting shaft, and the outer diameter of the copper sleeve being adapted to the inner diameter of the bushing.
[0023] Furthermore, it also includes a positioning plate, which is fixedly connected to the vehicle frame, and the rotating bracket is connected to the vehicle frame through the positioning plate;
[0024] The positioning hole is provided on the positioning plate, and the positioning rod passes through the positioning hole in sequence to connect with the vehicle frame.
[0025] Furthermore, the rotating bracket includes a shaft support and a bracket plate, the bracket plate being at least partially connected to the shaft support, and the bushing, copper sleeve, and connecting shaft being installed inside the shaft support;
[0026] The bracket plate is provided with a connection hole, and the locking assembly passes through the connection hole to connect with the support leg.
[0027] Furthermore, the rotating bracket also includes a bending support and a support plate, the support plate being connected to the bracket plate via the bending support, and the support plate being located between the vehicle frame and the bending support;
[0028] The bending support has a through hole, the support plate has a guide hole, and the positioning rod passes through the through hole, the guide hole, and the positioning hole in sequence to connect with the vehicle frame.

[0033] The rotatable outrigger bracket for mining trucks disclosed in this application has at least the following technical advantages:
[0034] 1. By setting a locking mechanism, which is connected to the rotating bracket, the locking mechanism is used to lock or unlock the rotation state of the rotating bracket, ensuring that the outriggers remain in the predetermined position during operation, preventing accidental rotation or movement, thereby improving the safety of the equipment. It also allows operators to easily lock or unlock the rotating bracket quickly through the locking mechanism, simplifying the operation process and improving work efficiency.

It should be understood that the specific embodiments described herein are merely illustrative of this disclosure and are not intended to limit it.

Therefore, the above terms should not be construed as limitations on this application.
[0050] The present application will now be described in further detail with reference to the accompanying drawings, see below. Figures 1 to 6 illustrate.
[0051] This embodiment provides a rotatable outrigger bracket for mining trucks, which is applied in the field of engineering machinery technology. Specifically, for example... Figures 1 to 6 As shown, the vehicle includes a frame 1, support legs 2, a connecting shaft 3, and a rotating bracket 4. Support legs 2 are connected to the frame 1 and support the frame 1. The frame 1 is connected to the support legs 2 via the connecting shaft 3, which is located to the side of the frame 1 and perpendicular to the frame 1 (i.e., the angle between the connecting shaft 3 and the frame 1 is 90°). The frame 1 has holes for inserting the connecting shaft 3, which is at least partially inserted into the frame 1 and welded to it. The rotating bracket 4 is connected to the support legs 2 and is located between the frame 1 and the support legs 2. The rotating bracket 4 can drive the support legs 2 to rotate around the connecting shaft 3. Rotating in the vertical plane, the plane in which the outrigger 2 rotates is perpendicular to the plane in which the frame 1 rotates, i.e., its rotation angle is 90°, allowing the outrigger 2 to rotate relative to the frame 1. This allows the outrigger 2 to rotate from a state parallel to the ground to a state perpendicular to the ground, improving the flexibility of the outrigger 2. When traveling on rough terrain, the rotation function of the outrigger 2 allows it to be retracted or rotated to a more compact position when not in use, effectively saving space and avoiding the space occupation problems that may be caused by the traditional outrigger 2 structure. This enables mining trucks to better adapt to the environment in complex terrain.
[0052] Specifically, such as Figure 1 As shown, it also includes a locking mechanism 5, which is connected to the rotating bracket 4. The locking mechanism 5 is used to lock or unlock the rotation state of the rotating bracket 4, ensuring that the outrigger 2 remains in the predetermined position during operation, preventing accidental rotation or movement, thereby improving the safety of the equipment. It also allows the operator to easily and quickly lock or unlock the rotating bracket 4 through the locking mechanism 5, simplifying the operation process and improving work efficiency. The frame 1 is provided with a positioning hole 91 for the locking mechanism 5 to be inserted. The locking mechanism 5 passes through the rotating bracket 4 and the positioning hole 91 in sequence and connects to the frame 1, ensuring that the rotating bracket 4 will not easily become loose or displaced during use, reducing the risk of the rotating bracket 4 tilting or becoming out of control, and improving the safety of use.
[0053] Furthermore, such as Figure 4 As shown, the locking mechanism 5 includes a positioning rod 51 and a positioning element 52. The positioning element 52 is a pin structure, allowing the positioning rod 51 to pass through the rotating bracket 4 and the positioning hole 91 sequentially to connect with the frame 1. The positioning element 52 is used to lock or unlock the positioning rod 51. The end of the positioning rod 51 facing away from the frame 1 has a handle, which is mainly for the user to hold when the positioning rod 51 needs to be operated. At the end of the handle, there is also a clear mark indicating the direction of locking and unlocking, so that the operator can quickly and accurately complete the operation even in an emergency. The positioning rod 51 has a locking hole for the positioning element 52 to be inserted. The locking hole is adapted to the positioning element 52. When the positioning element 52 is inserted into the locking hole, the rotating bracket 4 and the frame 1 are locked. When the positioning element 52 is pulled out, the frame 1 and the rotating bracket 4 are unlocked, so that the rotating bracket 4 can be easily rotated around the connecting shaft 3.
[0054] like Figure 1 As shown, it also includes a locking assembly 6. The outrigger 2 is connected to the rotating bracket 4 via the locking assembly 6. The locking assembly 6 is used to lock or unlock the rotation state of the outrigger 2, ensuring that the outrigger 2 remains in the predetermined position during operation. Operators can easily and quickly lock or unlock the rotating bracket 4 via the locking assembly 6, thereby simplifying the operation process and improving work efficiency. There are at least multiple locking assemblies 6, with adjacent locking assemblies 6 spaced apart to ensure a stable locking effect at different angles. Furthermore, the locking assembly 6 is preferably made of corrosion-resistant and high-strength materials to ensure long-term reliability and durability. The locking assembly 6 includes a nut and a bolt, which cooperate to fix the outrigger 2 to the rotating bracket 4.
[0055] Furthermore, such as Figure 4As shown, a bushing 7 is fitted onto the outer surface of the connecting shaft 3. The bushing 7 is located between the rotating bracket 4 and the connecting shaft 3 to reduce friction between them and extend their service life. The bushing 7 has a mounting hole 71, and an adjusting component, namely an adjusting bolt, is installed inside the mounting hole 71. The adjusting component is mainly used to adjust the gap between the shaft 3 and the bushing 7, so that the rotating bracket 4 and the support leg 2 no longer rotate around the axis, thereby ensuring the stability and accuracy of the rotating bracket 4. The setting of the adjusting bolt allows users to adjust the gap size according to actual needs to adapt to different working environments and conditions. A copper sleeve 8 is provided between the bushing 7 and the connecting shaft 3. The copper sleeve 8 is fitted onto the connecting shaft 3, and the outer diameter of the copper sleeve 8 is matched with the inner diameter of the bushing 7. Through the cooperation of the bushing 7 and the copper sleeve 8, the friction and wear of the connecting shaft 3 can be effectively reduced, thereby reducing the energy consumption and maintenance costs of the connecting shaft 3, and improving the durability and stability of the connecting shaft 3.
[0056] In this embodiment, as Figures 3 to 6 As shown, the rotating bracket 4 includes a shaft support 41 and a bracket plate 42. The bracket plate 42 is at least partially fixedly connected to the shaft support 41. The bracket plate 42 is located on the side of the shaft support 41 away from the frame 1. The bushing 7, the copper sleeve 8, and the connecting shaft 3 are all installed inside the shaft support 41. The bracket plate 42 extends towards the support leg 2 and is at least partially close to the support leg 2. The shaft support 41 provides the necessary support to enable the connecting shaft 3 to operate stably and reduce vibration and displacement. The bracket plate 42 has a connecting hole through which the locking assembly 6 passes and connects to the support leg 2. The size of the connecting hole is adapted to the size of the locking assembly 6.
[0057] Furthermore, such as Figure 4 As shown, it also includes a bending support 43 and a support plate 44. The support plate 44 is fixedly connected to the bracket plate 42 through the bending support 43. The support plate 44 is located between the frame 1 and the bending support 43. The bending support 43 is provided with a through hole 431, and the support plate 44 is provided with a guide hole 441. The positioning rod 51 can pass through the through hole 431, the guide hole 441, and the positioning hole 91 in sequence to connect with the frame 1, so as to fix the rotating bracket 4 to the frame 1. The through hole 431, the guide hole 441, and the positioning hole 91 are coaxially arranged to ensure that the rotating bracket 4 can remain stable during use and avoid loosening due to vibration or external force.
[0058] Furthermore, it also includes a positioning plate 9, which is welded to the frame 1. The rotating bracket 4 is connected to the support leg 2 through the positioning plate 9. A connecting plate is set between the frame 1 and the support plate 44. The connecting shaft 3 is at least partially located inside the positioning plate 9. The positioning plate 9 and the support plate 44 are close together. The structural design of the positioning plate 9 enables it to withstand the force from the rotating bracket 4 while ensuring the stability of the connection with the rotating bracket 4. The positioning hole 91 is set on the positioning plate 9, and the positioning rod 51 can pass through the positioning hole 91 in sequence to connect with the frame 1. The positioning hole 91 and the positioning rod 51 are coaxially arranged. In addition, the material selection and thickness design of the positioning plate 9 take into account load-bearing capacity and durability, ensuring that it will not deform or be damaged during long-term use, thereby improving the service life of the positioning plate 9 and extending the service life of the overall structure.
[0059] Furthermore, an elastic element 45, which is a spring, is provided between the bending support 43 and the support plate 44. The elastic element 45 is sleeved on the locking mechanism 5 and has a compression function. When the elastic element 45 generates pre-pressure between the locking mechanism 5 and the bending support 43, it ensures the stability and reliability of the locking mechanism 5 when locking the rotating bracket 4. When the rotating bracket 4 needs to be adjusted, the compression function of the elastic element 45 allows the locking mechanism 5 to move within a certain range, thereby achieving flexible adjustment of the rotating bracket 4. In addition, the use of the elastic element 45 can also absorb some vibration and impact, further improving the stability and durability of the entire support system. Among them, a first washer 46 is provided between the side of the elastic element 45 near the bending support 43 and the bending support 43, and a second washer 47 is provided between the side of the elastic element 45 near the support plate 44 and the support plate 44. The positioning element 52 is disposed between the second washer 47 and the support plate 44. By providing the first washer 46 and the second washer 47, wear caused by direct contact between the elastic element 45 and the bending support 43 or the support plate 44 can be effectively prevented, thereby extending the service life of the elastic element 45.
[0060] Working principle: When the outrigger 2 needs to rotate, first tighten the locking assembly 6 to loosen the connection between the outrigger 2 and the rotating bracket 4. Then, pull the positioning rod 51 out of the frame 1. In this way, the rotating bracket 4 can drive the outrigger 2 to rotate 90° around the connecting shaft 3. After the rotation is completed, insert the positioning rod 51 into the frame 1 and tighten the locking assembly 6 again to fix the connection between the outrigger 2 and the rotating bracket 4. This can prevent accidental rotation during use. At this time, the rotating bracket 4 and the outrigger 2 will not be able to rotate around the connecting shaft 3.
[0061] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The descriptions of the embodiments above are only for the purpose of helping to understand the present application and its core ideas. It should be noted that those skilled in the art can make several improvements and modifications to the present application without departing from the principles of the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
