Description

Technical Field

[0001] This utility model relates to the field of mining technology, specifically a structure for a fixed base of a mining robotic arm. Background Technology

[0002] Mining robotic arms are mechanical devices used for ore mining and processing. They are usually fixed behind vehicles or the ground to work. When the project period is long, the robotic arm is usually installed on the ground for long-term stable operation.

[0003] Mining robotic arms need to be installed on the ground using mounting bases. Due to the large weight of the robotic arms and the heavy workload, the mounting bases at the bottom need to be firmly installed. However, ordinary mounting bases usually only improve stability by deep burial. Since the mounting base is a single unit, the reaction force experienced by the robotic arm during operation is transmitted to the mounting base. The contact surface between the mounting base and the soil is in the vertical direction, so the reaction force experienced by the robotic arm is transmitted horizontally to the soil. The vertical component of the force is difficult to eliminate by transmitting it to the soil, making the mounting base more prone to loosening. Therefore, a new type of mounting base structure is needed to solve this problem. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model proposes a fixed base structure for a mining robotic arm, which can evenly transmit the force on the robotic arm from the horizontal and vertical directions to the soil after being buried underground, thus avoiding the inability to transmit the vertical component of the force and causing the fixed base to loosen easily.

[0005] The technical solution to achieve the purpose of this utility model is as follows: a fixed base structure for a mining robotic arm, including a fixed base with an installation groove. Four support rods are fixedly connected to the bottom of the fixed base, and pressure plate assemblies are provided on the four support rods. The pressure plate assembly includes a fixed plate, a pressure plate, and spring hinges. Multiple sets of the fixed plates are fixedly connected to the four support rods. Multiple spring hinges are respectively provided on multiple fixed plates. Multiple pressure plates are respectively hinged to multiple fixed plates through multiple spring hinges. An adjustment assembly is provided on the fixed base.

[0006] Preferably, the adjusting component includes a vertical rod that is slidably connected to a fixed base, and each pressure plate has a semi-circular groove, through which the vertical rod passes.

[0007] Preferably, the adjustment assembly further includes baffles, and a plurality of baffles are fixedly connected to the vertical rod.

[0008] Preferably, the pressure plates are symmetrically distributed on both sides of the vertical rod, and each baffle is located above the two pressure plates.

[0009] Preferably, the adjusting assembly further includes a groove and a pull rod, the groove being formed on the vertical rod, and the pull rod being slidably connected inside the groove.

[0010] Preferably, the top end of the vertical rod is slidably connected to the inside of the mounting groove, and the pull rod is located at the top end of the vertical rod.

[0011] Compared with the prior art, the significant advantages of this utility model are: Firstly, in this utility model, by setting up support rods and pressure plate assemblies, a deep pit can be dug in the ground to accommodate the entire fixed base structure. Then, four support rods are placed in the pit, so that the fixed base is on the ground surface. The elastic force of the spring hinge will cause multiple pressure plates to be initially in a tilted state. Therefore, soil can be filled into the pit to bury the fixed base structure tightly. Since multiple pressure plates are in a tilted state, the soil will not be blocked by the pressure plates when filling the pit, but can completely fill the space in the pit, so that the bottom of each set of pressure plates is filled with soil.

[0012] Secondly, in this utility model, by setting an adjustment component, when filling the soil, the vertical rod can be pressed down by the pull rod, causing the vertical rod to move downward. When the vertical rod moves downward, the baffle on it also moves downward. When the baffle moves downward, it will press against the two sets of pressure plates below, causing the pressure plates to flip downward. When the pressure plates flip downward, the pressure plates gradually come to a horizontal state. During this process, the soil under the pressure plates will be compacted, ensuring that the soil in the pit is sufficiently compacted, improving the stability of the entire fixed base structure after installation. During this process, the amount of soil filled in the pit can be gradually increased, and the soil will be gradually compacted.

[0013] Thirdly, in this utility model, when the vertical rod is moved downward by manual pressing, the soil has great resistance when it is squeezed, so it is difficult for the vertical rod and the baffle to be completely pressed down to the horizontal position of each set of pressure plates. Therefore, the mining robotic arm can be installed in the installation groove. When the robotic arm is installed in the installation groove, the robotic arm will press down the vertical rod, so that the vertical rod is pressed down to the lowest position. At this time, the baffle will also press each set of pressure plates to the horizontal position. At this time, the soil in the pit will be completely compacted, improving the stability of the pressure plate assembly in the soil.

[0014] Fourthly, in this utility model, when the mining robotic arm is working, the reaction force on the robotic arm will be transmitted to the fixed base, the support rod below, and the entire pressure plate assembly. After the pressure plate assembly is subjected to force, it will transmit the force to the soil. Since there are multiple sets of pressure plates and they are arranged in layers, there is compacted soil between each layer of pressure plates. Therefore, the force can be transmitted not only horizontally to the pit wall, but also vertically to the soil in the pit. Thus, the pressure plate assembly, together with the support rod, can evenly distribute the force received in the horizontal and vertical directions to the soil, thereby improving the stability of the entire fixed base structure after it is buried in the soil.

[0017] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0018] This utility model provides an improved structure for a fixing base of a mining robotic arm. The technical solution of this utility model is as follows: like Figures 1-4 As shown, a mining robotic arm mounting structure includes a mounting base 1 with an installation groove 2. Four support rods 3 are fixedly connected to the bottom of the mounting base 1, and pressure plate assemblies 4 are provided on the four support rods 3. The pressure plate assembly 4 includes a fixing plate 41, a pressure plate 42, and spring hinges 43. Multiple sets of fixing plates 41 are fixedly connected to the four support rods 3. Multiple spring hinges 43 are respectively provided on multiple fixing plates 41. Multiple pressure plates 42 are respectively hinged to multiple fixing plates 41 through multiple spring hinges 43. An adjustment assembly 5 is provided on the mounting base 1.

[0019] Mounting slot 2 is used to install the robotic arm, while support rod 3 serves as the supporting structure for the fixed base structure and can be buried in a pre-dug pit. Multiple sets of pressure plates 42 are set between the four support rods 3, and soil can be filled between each set of pressure plates 42. This increases the contact area between the entire fixed base structure and the soil in the pit, so that the force on the fixed base structure can be transferred to the soil to the greatest extent, thus avoiding large stresses within the structure itself. When the spring hinge 43 is not subjected to external force, it will lift the pressure plate 42. This makes it easier for the soil to be filled evenly in the pit and fill the space between each layer of pressure plates 42, as the soil will not be blocked by the pressure plate 42 when filling the pit.

[0020] In this embodiment, the adjustment component 5 includes a vertical rod 51, which is slidably connected to the fixed base 1. Each pressure plate 42 has a semi-circular groove, and the vertical rod 51 passes through the semi-circular groove on each pressure plate 42.

[0021] In this embodiment, the adjustment component 5 further includes baffles 52, and a plurality of baffles 52 are fixedly connected to the vertical rod 51.

[0022] When the baffle 52 moves downward, it presses each set of pressure plates 42 downward together, thus pressing each set of pressure plates 42 to a horizontal state, thereby compacting the soil between each set of pressure plates 42. At the same time, the pressure plates 42 are used to separate the soil into layers. In subsequent use, the pressure plates 42 can indirectly transfer the force from the robotic arm above to the soil between each layer of pressure plates 42, using the soil to eliminate the force. The vertical spacing of each set of pressure plates 42 can be appropriately larger to facilitate filling more soil and improve the stability of the entire fixed base structure after installation and during use.

[0023] In this embodiment, the pressure plates 42 are symmetrically distributed on both sides of the vertical rod 51, and each baffle 52 is located above the two pressure plates 42.

[0024] In this embodiment, the adjustment component 5 further includes a groove 53 and a pull rod 54. The groove 53 is formed on the vertical rod 51, and the pull rod 54 is slidably connected to the inside of the groove 53. Since the vertical rod 51 is relatively thick, the pull rod 54 can be pulled out from the groove 53, which makes it easy to lift the vertical rod 51 to move it upward. When the vertical rod 51 is moved downward, it is only necessary to press it downward.

[0025] In this embodiment, the top end of the vertical rod 51 is slidably connected to the inside of the mounting groove 2, and the pull rod 54 is located at the top end of the vertical rod 51. When a robotic arm is installed in the mounting groove 2, the robotic arm can use itself to press the vertical rod 51 completely, thereby pressing the baffle 52 down to the maximum extent. At this time, each set of pressure plates 42 is in a horizontal state, and the soil between each set of pressure plates 42 is compacted.

[0026] The specific working method is as follows: First, dig a deep pit on the ground that is deep enough to accommodate the entire fixed seat structure. Then, put the four support rods 3 into the pit so that the fixed seat 1 is on the ground surface. The elastic force of the spring hinge 43 will cause the multiple pressure plates 42 to be initially in a tilted state. Therefore, soil can be filled into the pit so that the fixed seat structure is buried tightly. Since the multiple pressure plates 42 are in a tilted state, the soil will not be blocked by the pressure plates 42 when it is filled into the pit. Instead, it can completely fill the space in the pit so that the bottom of each set of pressure plates 42 is filled with soil.

[0027] When filling the pit with soil, the vertical rod 51 can be pressed down by the tie rod 54, causing the vertical rod 51 to move downward. When the vertical rod 51 moves downward, the baffle 52 on it will also move downward. When the baffle 52 moves downward, it will press against the two sets of pressure plates 42 below, causing the pressure plates 42 to flip downward. When the pressure plates 42 flip downward, the pressure plates 42 gradually become horizontal. During this process, the soil under the pressure plates 42 will be compacted, ensuring that the soil in the pit is compacted enough, improving the stability of the entire fixed base structure after installation. During this process, the amount of soil filled in the pit can be gradually increased, and the soil will be gradually compacted.

[0028] When the vertical rod 51 is moved downward by manual pressing, the soil has great resistance when it is squeezed, so it is difficult for the vertical rod 51 and the baffle 52 to be completely pressed down to the horizontal position of each set of pressure plates 42. Therefore, the mining robotic arm can be installed in the installation slot 2. When the robotic arm is installed in the installation slot 2, the robotic arm will press down the vertical rod 51, so that the vertical rod 51 is pressed down to the lowest position. At this time, the baffle 52 will also press each set of pressure plates 42 to the horizontal position. At this time, the soil in the pit will be completely compacted, improving the stability of the pressure plate assembly 4 in the soil.

[0029] When the mining robotic arm is working, the reaction force on the robotic arm is transmitted to the fixed base 1, the support rod 3 below, and the entire pressure plate assembly 4. After the pressure plate assembly 4 is subjected to force, it will transmit the force to the soil. Since there are multiple sets of pressure plates 42 and they are arranged in layers, there is compacted soil between each layer of pressure plates 42. Therefore, the force can be transmitted not only horizontally to the pit wall, but also vertically to the soil in the pit. Thus, the pressure plate assembly 4, together with the support rod 3, can evenly distribute the force received in the horizontal and vertical directions to the soil, thereby improving the stability of the entire fixed base structure after it is buried in the soil.

Matters not covered in this utility model are common knowledge to those skilled in the art.
