[0031] In the complex, rocky geological environment of large open-pit mines, excavators, as key mining equipment, rely heavily on their track rollers. These rollers not only bear the crucial responsibility of supporting the machine's weight and ensuring stable track operation, but also force the tracks to slip on the ground when the excavator turns. Under these extreme working conditions, a single-bucket truck semi-continuous mining process is typically employed, meaning that excavators are frequently under high-intensity working conditions. The track rollers are prone to internal structural damage due to prolonged overload operation. Currently, replacing these damaged heavy-duty excavator track rollers mainly relies on a combination of lifting equipment and manual labor. However, this method is inconvenient for personnel and consumes significant manpower and time.

[0032] After careful study, the applicant discovered that the existing methods for replacing excavator track rollers face multiple challenges. First, the current methods rely on manual correction and alignment, which is cumbersome and often takes a long time from preparation to completion. This not only increases the difficulty of operation but also easily leads to inaccurate positioning, affecting the quality of subsequent assembly. Furthermore, each replacement requires multiple workers to work together, consuming a significant amount of human resources. Especially under tight deadlines, insufficient manpower may delay production. The replacement of excavator track rollers also requires hoisting and manual operation, exposing workers directly to the risk of being injured by falling heavy objects. In addition, manual adjustment increases the possibility of accidents, posing a serious threat to the safety of workers.

[0033] The main purpose of this utility model is to propose an auxiliary tool for changing the track rollers of mining excavators to solve the problem of how to improve the convenience of changing track rollers.

[0034] Please see Figure 1 and Figure 2In one embodiment of this utility model, the mining excavator track roller replacement auxiliary tool 100 includes a frame 1, a bracket 2, and an adjustment mechanism 3. The bracket 2 is provided with a groove 2111 for supporting the track roller. The adjustment mechanism 3 includes a first adjustment component 31 and a second adjustment component 32. The bracket 2 is rotatably mounted on the first adjustment component 31, and the first adjustment component 31 can drive the bracket 2 to move relative to the frame 1 in a first direction. The first adjustment component 31 is movably mounted on the second adjustment component 32 so that the first adjustment component 31 can move relative to the second adjustment component 32 in a second direction. The second adjustment component 32 is movably mounted on the frame 1 so that the second adjustment component 32 can move relative to the frame 1 in a third direction. The first direction, the second direction, and the third direction are perpendicular to each other.

[0035] In this embodiment of the utility model, the first direction is the up-down direction, the second direction is the front-back direction, and the third direction is the left-right direction. The frame 1 is the basic structure of the entire mining excavator track roller replacement auxiliary tool 100, providing the necessary stability and strength to support other components. The bracket 2 is provided with a groove 2111 that matches the outer wall size of the track roller, which can stably support the track roller to be replaced. The adjustment mechanism 3 includes a first adjustment component 31 and a second adjustment component 32. Through the combined action of the first adjustment component 31 and the second adjustment component 32, multi-directional movement and rotation capabilities are achieved. Specifically, the bracket... The support roller is rotatably mounted on the first adjusting component 31, allowing the bracket 2 to rotate 360° relative to the first adjusting component 31. This allows the operator to adjust the rotation angle of the support roller to adapt to different work requirements or positions. The first adjusting component 31 can also drive the bracket 2 to move in the vertical and horizontal directions and in the front and back directions. The second adjusting component 32 can drive the first adjusting component 31 and the bracket 2 to move in the left and right directions, thereby realizing the position adjustment of the support roller in three dimensions. This ensures that the support roller can be accurately installed or removed, helping to avoid equipment failure or damage caused by improper positioning.

[0036] The technical solution of this utility model, by employing a bracket 2, a first adjusting component 31, and a second adjusting component 32, enables rapid positioning and adjustment of the support roller in three dimensions. This ensures that the support roller can be accurately installed or removed, making the installation and removal of the support roller simple and quick, reducing the time required for the entire replacement process, and effectively improving the convenience and production efficiency of support roller replacement. Furthermore, the first adjusting component 31 and the second adjusting component 32 enable automated or semi-automated replacement of the support roller, reducing the need for manual operation, alleviating the labor intensity of workers, and improving work efficiency. Compared with the current method of manual correction and alignment, the use of the mining excavator support roller replacement auxiliary tool 100 can reduce the number of personnel on site and the opportunity for direct contact with heavy objects, thereby significantly reducing the risk of accidents and improving the safety factor of workers. The mining excavator support roller replacement auxiliary tool 100 also provides additional safety protection through its stability and precise control characteristics, effectively preventing the support roller from accidentally moving or falling, and protecting surrounding personnel from potential injury.

[0037] Please see Figure 1 , Figure 2 and Figure 4 In one embodiment, the first adjustment component 31 includes a bracket 311 and a drive member 312. The bracket 311 is movably mounted on the second adjustment component 32, and the drive member 312 is detachably connected to the bracket 311. The bracket 2 includes a frame body 21 and a connector 22 connected to each other. The frame body 21 is provided with a groove 2111, and the connector 22 is rotatably mounted on the drive member 312. The drive member 312 can drive the frame body 21 to move in a first direction through the connector 22. Specifically, the frame body 21 is the main component that supports the support rollers, and it is provided with a groove 2111 to ensure that the support rollers can be stably placed on the frame body 21. The connector 22 is rotatably mounted on the drive member 312 so that the connector 22 can drive the frame body 21 to move relative to the drive member 312. The 0° rotation allows operators to adjust the rotation angle of the support rollers to adapt to different work requirements or positions. The bracket 311 is movably mounted on the second adjustment component 32, enabling the bracket 311 to drive the drive component 312 and the bracket 2 to move in the front-to-back direction. The drive component 312 provides power and can drive the frame body 21 to move in the up-down direction through the connecting component 22, thereby achieving high-precision positioning and flexible adjustment during the support roller replacement process and improving replacement efficiency. The drive component 312 is detachably connected to the bracket 311, allowing operators to easily install or remove the drive component 312 as needed, simplifying the maintenance and repair process, and also facilitating the quick replacement of different types of drive devices according to different task requirements.

[0038] Please see Figure 3In one embodiment, the connecting member 22 includes a rotary bearing 221 and a steel pipe 222. The steel pipe 222 is connected to the frame body 21. A mounting hole 2221 is provided at the end of the steel pipe 222 away from the frame body 21. The rotary bearing 221 is connected to the wall of the mounting hole 2221. The driving member 312 is connected to the rotary bearing 221, allowing the frame body 21 to rotate relative to the driving member 312. Specifically, the rotary bearing 221 provides low-friction rotational support, allowing the frame body 21 to rotate freely relative to the driving member 312 via the steel pipe 222 and the rotary bearing 221. One end of the steel pipe 222 is fixedly connected to the frame body 21, and the other end is provided with a mounting hole 222. 1. The steel pipe 222, used to house the rotary bearing 221, not only provides a stable mounting position for the rotary bearing 221, but also ensures the effectiveness and stability of the force transmission path from the drive component 312 to the frame body 21. The drive component 312 is connected to the rotary bearing 221, which allows the drive component 312 to drive the steel pipe 222 and the frame body 21 to move vertically through the rotary bearing 221, while also allowing the frame body 21 to rotate around the central axis of the rotary bearing 221. This simplifies the structure and gives the frame body 21 a high degree of flexibility, enabling it to adapt to different operating angle requirements and better accommodate various posture adjustments during the installation or removal of the support rollers. In addition, considering that different models and specifications of excavators may have different support roller sizes and structural characteristics, the drive component 312 and the rotary bearing 221 are designed to be detachably connected. This facilitates the timely replacement of the appropriate bracket 2 according to different types and sizes of support rollers, thereby increasing the practical value and market applicability of the mining excavator support roller replacement auxiliary tool 100.

[0039] According to one embodiment of the present invention, a bearing seat or a rotary bearing 221 can be directly installed on the frame body 21. The drive component 312 rotates in conjunction with the bearing seat or rotary bearing 221, thereby realizing the 360° rotation of the frame body 21. The structure is simple and easy to operate.

[0040] Please see Figure 1 and Figure 2In one embodiment, the second adjustment component 32 includes a first track 321 extending along a second direction. A first caster assembly 3111 is mounted on the support 311, and the first caster assembly 3111 rolls in cooperation with the first track 321. The first caster assembly 3111 includes at least two first casters 31111 spaced apart along the second direction. Specifically, the first track 321 extends along a front-rear direction, providing a movement path for the support 311, ensuring that the support 311 maintains linear motion during movement, which helps to achieve precise positioning of the support rollers. The first caster assembly 3111 includes at least two first casters. The specific number of first casters 31111 can be selected according to actual needs. Each first caster 31111 is mounted on the bracket 311 and forms a rolling engagement with the first track 321. By setting at least two first casters 31111, the load on the bracket 311 and the support 2 can be distributed, thereby extending the service life of the first casters 31111 and reducing the risk of wear or damage to the first track 321. This ensures the reliability and durability of the mining excavator support roller replacement auxiliary tool 100, and also guarantees stability and balance during movement, effectively preventing the bracket 311 from tilting and improving safety during use. In this embodiment, the first caster assembly 3111 includes two first casters 31111 spaced apart in the front-to-back direction, which enable the bracket 311 to move in the left-to-right direction.

[0041] Please see Figure 1 , Figure 2 and Figure 4In one embodiment, the bracket 311 includes a support plate 3112 and a first limiting frame 3113. The support plate 3112 is detachably connected to the driving member 312. The first limiting frame 3113 includes a first limiting plate 31131 and a second limiting plate 31132. A first limiting space 31133 is formed between the first limiting plate 31131 and the second limiting plate 31132 for the first track 321 to pass through. The first caster 31111 is rotatably mounted on the first limiting plate 31131 and the second limiting plate 31132. Specifically, the support plate 3112 is the main load-bearing part of the bracket 311, and the support plate 3112 is detachably connected to the driving member 312. The detachable connection design facilitates the installation and maintenance of the drive component 312 and allows for quick replacement of different types of drive devices as needed. Through the combined action of the first limiting plate 31131 and the second limiting plate 31132, an installation position is provided for the first caster 31111, and its range of movement is limited. This ensures the stable rolling of the first caster 31111 on the first track 321, reduces the risk of track deviation, ensures the stability and accuracy of the bracket 311 during movement, helps achieve precise positioning of the support rollers, and reduces the risk of the bracket 311 accidentally falling, thus improving the operational safety of the staff. In this embodiment, the number of first limiting plates 3113 is consistent with the number of first casters 31111 and they are set in a one-to-one correspondence, thereby improving the stability and accuracy of the bracket 311 during movement.

[0042] According to one embodiment of the present invention, the number of first limiting frames 3113 is less than the number of first casters 31111, and at least one first caster 31111 is rotatably mounted on the first limiting frame 3113, thereby preventing the first caster assembly 3111 from shifting and improving the stability and accuracy of the bracket 311 during movement.

[0043] Please see Figure 1 and Figure 2In one embodiment, the second adjustment component 32 further includes a second caster assembly 322, which is rotatably mounted on the first track 321. A second track 11 is provided on the frame 1, extending in a third direction. The second caster assembly 322 rolls in cooperation with the second track 11. The second caster assembly 322 includes at least two second casters 3221. Specifically, the second track 11 extends in a left-right direction, providing a movement path for the first adjustment component 31, ensuring that the first adjustment component 31 maintains linear motion during movement. This allows the support rollers to move freely in three mutually perpendicular directions, greatly increasing operational flexibility and facilitating precise positioning of the support rollers. To adapt to different working scenarios and needs, the second caster assembly 322 includes at least two second casters 3221. The specific number of second casters 3221 can be selected according to actual needs. Each second caster 3221 is installed on the first rail 321 and forms a rolling engagement with the second rail 11. By setting at least two second casters 3221, the load on the second adjustment assembly 32 and the bracket 2 can be distributed, thereby extending the service life of the second casters 3221 and reducing the risk of wear or damage to the second rail 11. This ensures the reliability and durability of the mining excavator support roller replacement auxiliary tool 100, and also ensures stability and balance during movement, effectively preventing the bracket 311 from tilting and improving the safety of use. In this embodiment, the second caster assembly 322 includes two second casters 3221, which are located at the two ends of the first track 321 respectively. The number of second tracks 11 is the same as the number of second casters 3221 and they are set in a one-to-one correspondence. The support 311 can move in the left and right directions by the two second casters 3221 rolling on the two second tracks 11 respectively.

[0044] Please see Figure 2 In this embodiment, the first track 321 includes a track body 3211 and a second limiting frame 3212. For ease of manufacturing and installation, the structure of the second limiting frame 3212 can be the same as that of the first limiting frame 3113. The second limiting frame 3212 is connected to the track body 3211, and the second caster 3221 is rotatably mounted on the second limiting frame 3212. The second limiting frame 3212 provides an installation position for the second caster 3221 and restricts its range of movement, ensuring that the second caster 3221 can roll stably on the track body 3211, reducing the risk of track deviation, ensuring the stability and accuracy of the second adjusting component 32 during movement, helping to achieve precise positioning of the support rollers, and also reducing the risk of the second adjusting component 32 accidentally falling, thus improving the safety factor of the operator. In this embodiment, the number of second limiting frames 3212 is the same as the number of second casters 3221 and they are set in a one-to-one correspondence, thereby improving the stability and accuracy of the support 311 during movement.

[0045] According to one embodiment of the present invention, the number of second limiting frames 3212 is less than the number of second casters 3221, and at least one second caster 3221 is rotatably mounted on the second limiting frame 3212, thereby preventing the second caster assembly 322 from shifting and improving the stability and accuracy of the bracket 311 during movement.

[0046] In this embodiment, both the first caster 31111 and the second caster 3221 can be directional pulleys, thereby enabling movement in the forward and backward direction and in the left and right direction.

[0047] Please see Figure 1 and Figure 2 In one embodiment, the number of first rails 321 is at least one, and the number of first caster assemblies 3111 and second caster assemblies 322 is consistent with the number of first rails 321 and is arranged in a one-to-one correspondence. Specifically, the specific number of first rails 321 can be selected according to actual needs. By increasing the number of first rails 321, the load on the bracket 311 and the support 2 is distributed, reducing the pressure on individual first casters 31111 and individual second casters 3221, significantly improving the overall load-bearing capacity of the mining excavator track roller replacement auxiliary tool 100, and making the mining excavator track roller... The auxiliary tool 100 can handle heavier track roller replacement tasks, reduce wear rate, extend the service life of the mining excavator track roller replacement auxiliary tool 100, and reduce maintenance costs and frequency. Multiple first rails 321 are spaced apart in the left-right direction, ensuring uniform distribution and support in this direction, preventing the support frame 311 from tipping over, improving the stability and reliability of the mining excavator track roller replacement auxiliary tool 100, reducing the risk of accidents, increasing the safety factor for operators, and eliminating the need for manual balancing, thus reducing operational difficulty. In this embodiment, there are two first rails 321, spaced apart in the left-right direction. The number of first caster assemblies 3111 and second caster assemblies 322 corresponds to the number of first rails 321. By setting two first rails 321, and providing two first caster assemblies 3111 and two second caster assemblies 322 on each first rail 321, stable movement of the support frame 311 in the front-back and left-right directions is achieved.

[0048] According to one embodiment of the present invention, the number of the first track 321, the first caster assembly 3111, and the second caster assembly 322 is one. By extending the width of the first track 321 and the first caster assembly 3111 in the left-right direction, the tilting of the support 311 in the left-right direction is prevented. By extending the width of the second track 11 and the second caster assembly 322 in the front-back direction, the tilting of the support 311 in the front-back direction is also prevented. This improves the stability and reliability of the auxiliary tool 100 for changing the support rollers of the mining excavator.

[0049] Please see Figure 1 , Figure 2 and Figure 4 In one embodiment, the driving component 312 includes a jack; and / or, the bracket 311 is provided with a slot 31121, and the driving component 312 engages with the slot 31121. Specifically, a jack is a common mechanical device, and this embodiment does not limit its specific structure. The jack can provide strong lifting force and is suitable for replacing the support rollers of heavy equipment such as mining excavators. The jack is also equipped with a fine adjustment function, which can achieve precise height positioning, thereby ensuring that the support rollers maintain a stable and accurate position during installation or disassembly. The operation of the jack is relatively simple. Lifting can be completed manually or hydraulically, reducing the skill requirements for operators. In this embodiment, the support plate 3112 on the bracket 311 is provided with a slot 31121. The jack engages with the slot 31121, thereby enabling quick installation and separation between the jack and the bracket 311. This simplifies the installation and maintenance process of the drive component 312 and also facilitates the quick replacement of different types of jacks according to different task requirements. The engagement also ensures a tight connection between the jack and the bracket 311, preventing slippage during movement and providing higher safety.
