[0020] The following describes the specific embodiments of the present application in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present application and are not intended to limit the present application.

[0021] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with exemplary embodiments.

[0022] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 This embodiment provides a roller installation machine 100 that can be used to install rollers on a crawler frame, particularly for a large-tonnage crawler crane. The crawler frame has a plurality of roller mounting holes on its underside for mounting rollers.

[0023] The roller installation machine 100 includes a mobile module 110, a position adjustment module 120, and an assembly module 130. Both the position adjustment module 120 and the assembly module 130 are positioned above the mobile module 110 and driven by the mobile module 110. This allows the roller installation machine 100 to move back and forth between the assembly station and the parts loading station, enabling the automated handling of parts (roller rollers and mounting shafts for assembly).

[0024] Specifically, the position adjustment module 120 is disposed on the movable module 110 and has X-axis movement adjustment freedom, Y-axis movement adjustment freedom, and Z-axis lifting adjustment freedom to achieve high-precision alignment adjustment and ensure smooth installation.

[0025] The assembly module 130 is disposed on the position adjustment module 120 and includes a push assembly 131 , a mounting shaft support assembly 132 , and a roller support assembly 133 sequentially arranged along the X-axis direction. The push assembly 131 can output telescopic motion along the X-axis direction.

[0026] Please also refer to Figure 5 The mounting shaft support assembly 132 is used to accommodate the mounting shaft, and the roller support assembly 133 is used to accommodate the rollers. The mounting shaft is coaxial with the axis of the rollers and parallel to the X-axis. Therefore, when installing the rollers, the mounting shaft is simply pushed along the X-axis by the push assembly 131 to insert it into the corresponding roller mounting holes and roller shaft holes.

[0027] Furthermore, an escape groove is provided between the mounting shaft support assembly 132 and the roller support assembly 133. The width of the escape groove is consistent with the thickness of the wall on one side of the track frame. Thus, when the position adjustment module 120 drives the assembly module 130 upward in the Z-axis direction, the escape groove allows the wall on one side of the track frame to engage, ensuring that the rollers can be fed into the mounting position on the lower side of the track frame and aligned with the roller mounting holes on the track frame, facilitating subsequent assembly.

[0028] The position adjustment module 120 and assembly module 130 of the roller installation machine 100 provided in this embodiment are both mounted on the mobile module 110. This allows the roller installation machine 100 to be driven by the mobile module 110 to retrieve and transport materials. The installation shaft support assembly 132 and roller support assembly 133 on the assembly module 130 can be loaded with the installation shaft and rollers, respectively. When the rollers need to be installed, the roller installation machine 100 moves the loaded installation shaft and rollers below the track frame's mounting position. The position adjustment module 120 then fine-tunes the position of the installation shaft and rollers to align them with the track frame's roller mounting holes. The push assembly 131 then pushes the installation shaft into the roller mounting holes and rollers for installation.

[0029] Compared with the manual assisted installation in the prior art, the roller installation machine 100 provided in this embodiment realizes automatic installation without manual operation, reduces labor intensity, and improves operation safety. At the same time, the roller installation machine 100 integrates the carrying and installation functions, simplifies the process, and further improves operation efficiency.

[0030] In order to more clearly describe the technical solution of the present application, the following describes the supporting roller installation machine 100 provided in this embodiment, specifically as follows: See also Figure 1 、 Figure 5 and Figure 6 The above-mentioned mobile module 110 includes a supporting frame 111 and a walking mechanism 112. The walking mechanism 112 is arranged below the supporting frame 111. The walking mechanism 112 has at least four walking wheels, and the four walking wheels are distributed at the four corners of the supporting frame 111. The walking mechanism 112 drives the four walking wheels to rotate through a motor and can realize electronically controlled steering.

[0031] Furthermore, the traveling mechanism 112 is equipped with an energy storage battery that powers the motor, enabling electric travel and steering. As will be appreciated, the traveling mechanism 112 has both rapid and slow movement capabilities. Rapid movement involves moving the vehicle to the loading area for loading (installing rollers and mounting axles) and returning to the installation area (where the track frame is fixed) for installation. Slow movement allows for fine-tuning in both directions, allowing for fine-tuning of the X and Y positions of the loaded rollers and mounting axles during installation.

[0032] The middle portion of the carrying frame 111 is sunken to form a mounting surface 1110 for mounting the position adjustment module 120 . This can reduce the overall height and center of gravity of the track roller installation machine 100 , while enhancing its stability during carrying and transportation.

[0033] Please participate Figure 1 、 Figure 5 and Figure 7The position adjustment module 120 includes an X-axis displacement adjustment assembly 121, a Y-axis displacement adjustment assembly 122, and a Z-axis lift adjustment assembly 123. The X-axis displacement adjustment assembly 121 is mounted on the mounting surface 1110 of the carriage 111, the Y-axis displacement adjustment assembly 122 is mounted on the X-axis displacement adjustment assembly 121, and the Z-axis lift adjustment assembly 123 is mounted on the Y-axis displacement adjustment assembly 122.

[0034] Among them, the X-axis displacement adjustment component 121 can drive the Y-axis displacement adjustment component 122 and the Z-axis lifting adjustment component 123 to move and adjust in the X-axis direction. The Y-axis displacement adjustment component 122 can drive the Z-axis lifting adjustment component 123 to move and adjust in the Y-axis direction. The Z-axis lifting adjustment component 123 is provided with the above-mentioned assembly module 130, and the Z-axis lifting adjustment component 123 can provide lifting adjustment for the assembly module 130 in the Z-axis direction. In this way, the assembly module 130 can have the freedom of movement adjustment in the X-axis, the freedom of movement adjustment in the Y-axis, and the freedom of lifting adjustment in the Z-axis, so as to facilitate precise alignment during the installation process.

[0035] Specifically, the X-axis displacement adjustment component 121 includes an X-axis sliding platform 1210 and an X-axis sliding drive mechanism. The X-axis sliding platform 1210 is slidably set on the supporting frame 111. The sliding direction of the X-axis sliding platform 1210 is the X-axis direction. The X-axis sliding drive component is set on the supporting frame 111 and is driven and connected to the X-axis sliding platform 1210. The X-axis sliding drive component can output linear motion along the X-axis direction.

[0036] The Y-axis displacement adjustment component 122 includes a Y-axis sliding platform 1220 and a Y-axis sliding drive mechanism. The Y-axis sliding platform 1220 is slidably set on the X-axis sliding platform 1210. The sliding direction of the Y-axis sliding platform 1220 is the Y-axis direction. The Y-axis sliding drive component is set on the supporting frame 111 and is driven and connected to the Y-axis sliding platform 1220. The Y-axis sliding drive component can output linear motion along the Y-axis direction.

[0037] The Z-axis lifting adjustment assembly 123 includes a lifting platform 1230 and a Z-axis lifting drive mechanism 1231. The lifting platform 1230 is set on the Y-axis sliding platform 1220, and the assembly module 130 is set on the lifting platform 1230. The Z-axis lifting drive mechanism 1231 is used to drive the lifting platform 1230 to move up and down in the Z-axis direction.

[0038] Among them, the upper platform and the lower platform of the lifting platform 1230 are arranged in a positional manner and the scissor-type movable support frame 200 is arranged between the upper platform and the lower platform. The lower platform is arranged on the Y-axis sliding platform 1220, and the assembly module 130 is arranged on the upper platform.

[0039] Optionally, the X-axis sliding drive mechanism, the Y-axis sliding drive mechanism, and the Z-axis lifting drive mechanism 1231 can be selected as oil cylinders, electric cylinders, or motor screw mechanisms, etc. It should be understood that the above is only an example and does not limit the scope of protection of this application.

[0040] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 In this embodiment, the mounting shaft support assembly 132 includes a first support base 1320. A first positioning slot 1321 is provided on the first support base 1320 for positioning the mounting shaft. The length of the first positioning slot 1321 aligns with the X-axis. Furthermore, the opening width of the first positioning slot 1321 gradually decreases from top to bottom along the Z-axis. This facilitates automatic centering and rapid positioning by leveraging the cylindrical shape and deadweight of the mounting shaft. The push assembly 131 is positioned at the end of the first support base 1320 away from the roller support assembly 133.

[0041] Furthermore, considering that the diameter of the mounting shaft's head is larger than the shaft's diameter, in this embodiment, the first positioning slot 1321 is configured in two sections along the X-axis. The section closest to the pusher assembly is defined as a wide slot section 1321a, which accommodates the mounting shaft's head area. The length of wide slot section 1321a along the X-axis satisfies the maximum horizontal travel of the mounting shaft during installation. The section further from the pusher assembly is defined as a V-shaped positioning section 1321b, which positions the shaft.

[0042] The supporting wheel installation machine 100 also includes an installation shaft preparation module 140, which is arranged on the Y-axis displacement adjustment component 122 of the position adjustment module 120 and is located on one side of the installation shaft support component 132. The installation shaft preparation module 140 can store the installation shaft and is used to transport the installation shaft to the first support seat 1320.

[0043] See also Figure 1 、 Figure 2 、 Figure 5 and Figure 8 The mounting shaft preparation module 140 includes a first material preparation rack 141 and a first material blocking mechanism 142. The first material preparation rack 141 is arranged near the first support base 1320, and the bottom of the first material preparation rack 141 is tilted toward one side of the first support base 1320. The first material blocking mechanism 142 is arranged on the first material preparation rack 141 and has a material blocking state and a release state.

[0044] Among them, when in the blocking state, the first blocking plate on the first blocking mechanism 142 is exposed on the bottom of the first material preparation bin rack 141; when in the released state, the first blocking plate on the first blocking mechanism 142 is retracted to the bottom of the first material preparation bin rack 141, so that the weight of the mounting shaft is used to roll from the bottom of the first material preparation bin rack 141 to the first support seat 1320.

[0045] The first material blocking mechanism 142 includes the first material blocking plate and a first material blocking driver. The first material blocking driver can drive the first material blocking plate to extend and retract in the Z-axis direction so that the first material blocking plate can be selectively exposed at the bottom of the first material preparation bin 141.

[0046] Optionally, the first material-blocking driving member may be an air cylinder, an oil cylinder, an electric cylinder or a motor screw mechanism.

[0047] See also Figure 4 and Figure 5 In this embodiment, the installation shaft support assembly 132 also includes a guide plate 1322, which is arranged at one end of the first support seat 1320 away from the supporting wheel support assembly 133 and forms a guide groove 1322a between the first support seat 1320, and the guide groove 1322a is used for limiting and guiding the head of the installation shaft conveyed by the installation shaft preparation module 140 (limiting and guiding when the installation shaft rolls).

[0048] The roller support assembly 133 includes a second support base 1330 and a linear drive mechanism 1331. The second support base 1330 includes at least two support blocks 1330a spaced apart along the X-axis. The linear drive mechanism 1331 is drivingly connected to the support block 1330a at the end away from the mounting shaft support assembly 132. The linear drive mechanism 1331 can output telescopic movement along the X-axis. This allows for adjustable spacing between the two support blocks to accommodate the load-bearing positioning of different roller models.

[0049] Among them, a second positioning slot 1330b is formed on each support block 1330a, and the length direction of the second positioning slot 1330b is consistent with the X-axis direction. From top to bottom along the Z-axis direction, the opening width of the second positioning slot 1330b gradually decreases, so that it is convenient to utilize the shape and deadweight of the cylindrical structure of the supporting wheel for automatic centering and rapid positioning.

[0050] See also Figure 4 and Figure 5 In this embodiment, the second support seat 1330 includes two support blocks 1330a arranged at intervals along the X-axis direction, and a limiting block 1332 is provided on the side of the two support blocks 1330a facing away from each other. A clamping space for clamping the supporting roller is formed between the limiting blocks 1332 on the two support blocks 1330a to limit the axial limit of the supporting roller, prevent the axial position of the supporting roller from shifting, and improve the positioning accuracy.

[0051] Optionally, the linear drive mechanism 1331 may be an oil cylinder, an electric cylinder, or a motor screw mechanism, etc. It should be understood that the above is only an example and is not intended to limit the scope of protection of this application.

[0052] Furthermore, the top of the limit block 1332 is lower than the support surface of the installation shaft support assembly 132, so that when the push assembly 131 pushes the installation shaft to move along the X-axis, the limit block 1332 will not interfere with the movement of the installation shaft.

[0053] See also Figure 4 In some embodiments, the roller support assembly 133 further includes a visual monitoring module 1333. This visual monitoring module 1333 is located on a support block 1330a, which is located away from the mounting shaft support assembly 132. It is used to collect image information to determine whether the roller shaft holes are aligned, allowing for real-time alignment determination using graphical information. Furthermore, this graphical information can be wirelessly transmitted to a display terminal for display, allowing operators to more intuitively monitor the current alignment status. Furthermore, the position adjustment module 120 can be controlled based on the alignment status to perform fine-tuning of the alignment, ensuring rapid installation of the rollers and improving work efficiency.

[0054] Optionally, the display end may be a computer monitor, a mobile phone / tablet display, or a display integrated in a remote control.

[0055] In some embodiments, a vision and laser positioning system may be further configured on the track roller installation machine 100 to achieve fully automatic assembly of the track rollers of a large-tonnage crawler frame through system program control.

[0056] The roller support assembly 133 also includes a first resistance sensing module (not shown). This module is located on a support block 1330a, distal from the mounting shaft support assembly 132, and is configured to engage the end surface of the roller. This first resistance sensing module can detect the resistance experienced during roller assembly in real time and, based on this resistance signal, determine whether the mounting shaft is stuck.

[0057] Furthermore, a second resistance sensing module (not shown) may be provided on the push assembly 131 to directly detect the magnitude of the resistance experienced by the mounting shaft during assembly.

[0058] The roller installation machine 100 can be equipped with an alarm (not shown) on the mobile module 110. When the resistance detected by the first resistance sensing module and / or the second resistance sensing module exceeds a preset threshold, an alarm signal (such as a buzzer and flashing warning light) is emitted, simultaneously halting the roller installation machine 100. Once the problem is resolved, the machine can be restored with a one-button reset.

[0059] Optionally, the first resistance sensing module and the second resistance sensing module can be selected from strain gauges or pressure sensors.

[0060] See also Figure 2 、 Figure 4 and Figure 5 In this embodiment, the horizontal push assembly 131 includes a horizontal push drive mechanism 1310 and a horizontal push block 1311. The horizontal push drive mechanism 1310 is disposed at the end of the mounting shaft support assembly 132 away from the roller support assembly 133. The horizontal push block 1311 is mounted on the output end of the horizontal push drive mechanism 1310. The horizontal push drive mechanism 1310 is used to drive the horizontal push block 1311 to move along the X-axis. Furthermore, a fixed guide rail 134 can be provided along the X-axis on the mounting shaft support assembly 132. An extended guide arm 1312 is provided on one side of the horizontal push block 1311. This guide arm is equipped with a slider that slidably engages with the fixed guide rail 134, ensuring smoother assembly of the mounting shaft.

[0061] Optionally, the horizontal push drive mechanism 1310 can be selected as an oil cylinder, an electric cylinder, or a motor screw mechanism. It should be understood that the above is only an example and does not limit the scope of protection of this application. In this way, when the horizontal push drive mechanism 1310 is selected as an oil cylinder, the second resistance sensing module can be selected as an oil pressure sensor provided at the oil filling port on the oil cylinder. Preferably, the horizontal push drive mechanism 1310 can be selected as a multi-stage oil cylinder to reduce the length of the horizontal push mechanism in the X-axis direction, making the entire device more compact.

[0062] See also Figure 1 、 Figure 2 、 Figure 5 and Figure 8 The roller installation machine 100 further includes a roller preparation module 150. The roller preparation module 150 is disposed on the Y-axis displacement adjustment assembly 122 of the position adjustment module 120 and is located on one side of the roller support assembly 133. The roller preparation module 150 can store rollers and is used to transport the rollers to the second support seat 1330. In this embodiment, considering the large size of the rollers, to ensure that the number of rollers loaded at one time by the roller installation machine 100 corresponds to the number of installation shafts, two roller preparation modules 150 are provided. The two roller preparation modules 150 are arranged on both sides of the roller support assembly 133, and each roller preparation module 150 can load at least one roller.

[0063] Specifically, the supporting wheel preparation module 150 includes a second material preparation bin rack 151 and a second material blocking mechanism 152. The second material preparation bin rack 151 is arranged close to the second support seat 1330.
