Description

Technical Field

[0001] The utility model relates to the field of tunnel equipment, in particular to a rotating working mechanism of an anchor-grouting integrated machine. Background Art

[0002] In tunnel construction and underground engineering construction, anchor grouting trolleys are important operating equipment and are widely used in many construction tasks such as drilling, installing anchor rods, and grouting. However, in the existing technology, the design of anchor grouting trolleys has many shortcomings, which affect the operating efficiency and the simplicity of the construction process. Traditional anchor grouting trolleys mostly adopt a single workstation design. Switching between each workstation requires tedious manual operation or equipment translation, resulting in a long operating time of the equipment, complicated operating procedures, and reduced overall construction efficiency. In addition, due to the lack of a flexible switching structure, some equipment has a large lag when switching between workstations, making it difficult to meet the efficient operation requirements in complex projects.

[0003] Another issue with workstation switching in traditional equipment is the imperfect rotational mechanism. In existing technology, the rotating mechanism is typically simple and cannot effectively achieve rapid switching between multiple workstations. This limitation not only results in the equipment occupying a large construction space, but also easily affects construction accuracy due to structural sway. This makes it difficult to meet the requirements of fast, efficient, and continuous construction, especially in high-intensity construction scenarios. Utility Model Content

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] An embodiment of the present invention provides a rotary working mechanism for an anchor grouting integrated machine, including:

[0039] Please refer to the attached Figure 1 - attached Figure 3 , a rotary base 1, a total of multiple groups are respectively installed on both sides of the vehicle body, used to support the rotary frame 3 and realize the basic support of the entire rotary mechanism; the rotary base 1 is connected to the rotary shaft 2 through a bearing 14, and the bearing 14 includes a combined structure of a ball bearing and a thrust bearing, used to support the relative rotational movement between the rotary base 1 and the rotary shaft 2.

[0040] Specifically, the rotary base 1 consists of multiple groups, which are respectively installed on both sides of the vehicle body, constituting the basic support structure of the entire rotary working mechanism. Each group of rotary bases 1 is connected to the rotary shaft 2 through a bearing 14, ensuring that the rotary frame 3 can achieve precise rotary operations on the basis of the vehicle body stability. The design of the rotary base 1 fully considers the requirements of the anchor grouting trolley in different working environments, and its stable support role provides a solid foundation for the rotary mechanism. In order to ensure the smoothness during rotation and the durability for long-term use, the support bearing 14 of the rotary base 1 adopts a combined structure of a ball bearing and a thrust bearing. This combined structure can effectively reduce the friction between the rotary shaft 2 and the rotary base 1, and at the same time bear radial and axial loads, thereby maintaining the smooth rotation of the rotary frame 3 during actual operation and improving the working efficiency of the entire mechanism.

[0041] Please refer to the attached Figure 4 , the ball bearing part of the bearing 14 is mainly used to bear the radial load generated during the rotational movement, ensuring that the rotary frame 3 can still maintain good rotational performance when working under heavy load or high pressure. The thrust bearing is specifically used to bear the axial load of the rotary shaft 2 along the axial direction. Especially when the anchor grouting trolley is performing high-intensity drilling operations, the thrust bearing can effectively resist the axial stress caused by the change of the upper and lower pressures of the equipment. Through this double protection, the relative rotational movement between the rotary base 1 and the rotary shaft 2 is precisely controlled, avoiding equipment wear or performance degradation caused by uneven loads or excessive friction.

[0042] In addition, the multiple sets of design of the rotating base 1 not only improve the stability of the entire system, but also can be adjusted according to specific construction requirements to adapt to different tunnel environments and operation scenarios. The independent installation of each rotating base 1 further enhances the flexibility of the grouting jumbo, ensuring that the rotating frame 3 can smoothly complete the switching of each working station whether in a narrow tunnel space or a complex construction environment.

[0043] Please refer to the appendix Figure 4 , the rotating shaft 2, is fixedly connected to the rotating base 1 through a connection key 13 and is used to drive the rotating frame 3 to rotate;

[0044] Specifically, the rotating shaft 2 is fixedly connected to the rotating base 1 through the connection key 13, and its main function is to drive the rotating frame 3 to perform a rotating motion. The rotating shaft 2 is one of the core components of the rotating working mechanism of the entire grouting jumbo, bearing the weight and motion requirements of the rotating frame 3 and its attached working mechanisms. The design of the connection key 13 ensures the firm connection between the rotating shaft 2 and the rotating base 1, avoiding loosening or displacement during the rotation process, thereby ensuring the smooth switching of the rotating frame 3 between each working station.

[0045] The rotating shaft 2 not only plays the role of bearing the rotating frame 3, but also must ensure its smoothness and accuracy during rotation. Through the precise cooperation of the connection key 13, the rotating shaft 2 can effectively transmit the rotational power under the support of the rotating base 1, enabling the rotating frame 3 to achieve precise angle adjustment. Whether it is drilling, bolt installation, or other operations, the rotating shaft 2 can maintain a stable rotational motion at different working positions and ensure coordinated operation with other working components.

[0046] In addition, the design of the rotating shaft 2 takes into account the load requirements in a high-intensity working environment and can withstand multiple loads from the rotating frame 3 and the rock drilling mechanism and bolt mechanism it bears. Through the connection key 13, the close combination between the rotating shaft 2 and the rotating base 1 effectively prevents torsion or detachment under high loads, further enhancing the working reliability and safety of the entire mechanism. This connection method not only improves the load-bearing capacity of the rotating shaft 2, but also extends the service life of the equipment, and can maintain excellent performance under various complex construction conditions.

[0047] Please refer to the appendix Figure 4 , the rotating frame 3, is used to carry the rock drilling mechanism assembly 8, the bolt mechanism assembly 9, and the air duct assembly 10, and realizes the switching of working stations through the rotating shaft 2;

[0048] The jacking oil cylinder 4 is hinged to the rotary frame 3 and keeps in a jacked state against the wall during operation; the jacking oil cylinder 4 is hinged to the rotary frame 3, and its installation position is at the front end of the rotary frame 3. The jacking oil cylinder 4 and the rotary frame 3 act together to maintain stable support against the wall during the operation. The rock drilling mechanism assembly 8 is installed inside the rotary frame 3 through a sliding connection. The rock drilling mechanism assembly 8 includes a propulsion beam and a propulsion oil cylinder, and is driven by a compensation oil cylinder to achieve forward and backward movement during rock drilling operation.

[0049] Specifically, the jacking oil cylinder 4 is connected to the rotary frame 3 through a hinge structure and is located at the front end position of the rotary frame 3. The function of the jacking oil cylinder 4 is to maintain close contact with the tunnel wall during the operation, thereby providing stable support for the entire grouting jumbo. Due to its hinge design with the rotary frame 3, the jacking oil cylinder 4 can maintain independent movement during the rotation or angle adjustment of the rotary frame 3, ensuring stable contact with the wall at all times. This structural design enables the grouting jumbo to reliably provide support force even when the angle of the rotary frame 3 changes during operations such as drilling and bolt installation.

[0050] Please refer to the attached Figure 4 - attached Figure 5 , the combined action of the jacking oil cylinder 4 and the rotary frame 3 not only maintains the overall stability of the equipment, but also effectively offsets the reaction forces that may occur during operation through this precise hinge position distribution. Especially in high-pressure drilling or complex operating environments, the presence of the jacking oil cylinder 4 can ensure that the rotary frame 3 does not displace or swing unnecessarily when subjected to external impacts or vibrations, maintaining the operation accuracy and safety of the equipment.

[0051] At the same time, the rock drilling mechanism assembly 8 is installed inside the rotary frame 3 by means of a sliding connection. The rock drilling mechanism assembly 8 consists of a propulsion beam and a propulsion oil cylinder. During the operation, the propulsion oil cylinder drives the rock drilling mechanism to move forward and backward through a compensation oil cylinder, thereby completing the drilling task. The design of the compensation oil cylinder can fine-tune the rock drilling mechanism at different operating positions, ensure the precise positioning of the drill bit, and avoid affecting the operation quality due to the irregularity of the tunnel wall.

[0052] The encoder 5 is installed at the rear end of the rotating shaft 2 and is used to monitor the swing angle of the rotary frame 3 in real time; the encoder 5 is connected to the rotating shaft 2. The encoder 5 is used to measure the swing angle of the rotary frame 3 in real time, and the data feedback of the encoder 5 controls the start and stop of the rotating oil cylinder 6 of the propulsion beam to ensure that the rotary frame 3 switches to the correct working position.

[0053] Please refer to the attached Figure 6, the advancing beam rotating oil cylinder 6 connects the rotating base 1 and the rotating frame 3 and is used to push the rotating frame 3 to switch between different working positions; the copper sleeve 7 is arranged between the rotating shaft 2 and the rotating frame 3 and is used to reduce friction during rotation; the rod-changing gripper 11 is arranged on one side of the bolt bin assembly 15.

[0054] Specifically, as a key executing component of the rotating system, the advancing beam rotating oil cylinder 6 is hydraulically driven to achieve precise movement of the rotating frame 3, so as to accurately switch each working component of the bolt grouting trolley to the corresponding position. Whether it is for drilling operations or bolt installation, the power transmission of the rotating action is realized through the advancing beam rotating oil cylinder 6. The setting of this oil cylinder enables the rotating frame 3 to switch between multiple working positions at a controllable speed and in a stable manner, ensuring the efficient operation of the equipment in various working environments.

[0055] The copper sleeve 7 is arranged between the rotating shaft 2 and the rotating frame 3. As an important supporting and lubricating component, the main function of the copper sleeve 7 is to reduce the frictional force generated during rotation. By using the copper sleeve 7 at the contact part between the rotating shaft 2 and the rotating frame 3, the friction and wear caused by direct metal contact can be effectively reduced, and at the same time, the flexibility and durability of the rotating system are improved. The high wear resistance and low friction coefficient of copper material enable it to extend the service life of the equipment and reduce maintenance requirements when bearing the loads of the rotating frame 3 and the rotating shaft 2. This design ensures that the rotating mechanism can still maintain smooth rotation operation during high-frequency operations.

[0056] Please refer to the appendix Figure 5 , the bolt mechanism assembly 9 is installed on the outside of the rotating frame 3 through a sliding connection. The bolt mechanism assembly includes a compensation oil cylinder, an advancing beam, an advancing oil cylinder, a front tightening device, the center of the thruster 12, a front pulley assembly, a rear pulley assembly, and a bolt bin assembly 15. Among them, the advancing oil cylinder is used to push the bolt for installation and fixation.

[0057] The air duct assembly 10 is installed between the rotating frame 3 and the rock drilling mechanism assembly 8. The air duct assembly moves back and forth through the telescoping of the oil cylinder, and the connection of the air duct is coaxially arranged with the rock drilling mechanism assembly 8.

[0058] Please refer to the appendix Figure 5 - appendix Figure 6 , the rod-changing gripper 11 grabs the bolt and pushes it to the center of the thruster 12. The rod-changing gripper 11 swings through a robotic arm and moves from the bolt bin assembly 15 to the center of the thruster 12. The rod-changing gripper 11 is also used to support the bolt. The gripper and the center of the thruster 12 work in coordination. When the bolt moves to the center of the thruster 12, the rod-changing gripper 11 will automatically reset to its original position and wait for the next grab.

[0059] Specifically, its operation process relies on the swing control of the robotic arm. After the rod-changing gripper 11 grabs a bolt from the bolt bin assembly 15, it moves along a set path and transports the bolt to the working position of the thruster center 12. The precise control of the robotic arm ensures the stability and controllability of the gripper's swing process, guaranteeing the smooth transportation of the bolt between workstations. Through this grasping and transportation process, the rod-changing gripper 11 effectively supports the bolt installation operation of the bolt injection trolley and realizes automated operation.

[0060] The rod-changing gripper 11 is not only responsible for the grasping and transportation of bolts but also undertakes the support function of bolts simultaneously. During the process of the bolt moving from the bolt bin assembly 15 to the thruster center 12, the gripper firmly supports the bolt, preventing it from shaking or displacing during movement or swinging. The gripper and the thruster center 12 work together. When the bolt is successfully moved to the thruster center 12, the thruster takes over the subsequent installation work of the bolt, and at this time, the rod-changing gripper 11 will automatically reset. The automatic reset function of the gripper enables it to immediately return to the initial position after completing a grasping task and prepare for the next bolt grasping operation.

[0061] Working principle: Move the bolt injection trolley to the construction position, start the equipment, check the rotating base 1, confirm that it supports the rotating frame 3 and is connected and fixed through the rotating shaft 2, and make the jacking cylinder 4 contact the tunnel wall surface to complete the jacking operation;

[0062] Start the rotating beam rotating cylinder 6 to make the rotating frame 3 rotate around the rotating shaft 2, switch to the predetermined working position, the encoder 5 monitors the swing angle of the rotating frame 3 and controls the rotating beam rotating cylinder 6 to stop. The copper sleeve 7 is located between the rotating shaft 2 and the rotating frame 3 to assist the rotation process;

[0063] After the rotating frame 3 switches to the drilling working position, start the rock drilling mechanism assembly 8, and complete the drilling operation through the rotating beam and the propulsion cylinder, and use the compensation cylinder to adjust the position of the drill bit;

[0064] After the rotating frame 3 switches to the bolt installation working position, start the bolt mechanism assembly 9, which includes a rotating beam, a propulsion cylinder, a front jacking device, and a thruster center 12, to complete the bolt installation operation, and the bolt library rotating mechanism 15 rotates the bolt to the installation angle;

[0065] Start the rod-changing gripper 11, grab the bolt from the bolt library rotating mechanism 15, move to the position of the thruster center 12, and the rod-changing gripper 11 automatically resets after the thruster completes the bolt operation;

[0066] Use the air duct assembly 10 to provide air flow. The air duct assembly 10 moves back and forth through the telescopic cylinder and remains coaxial with the rock drilling mechanism assembly 8;

[0067] After completing one drilling and bolt installation operation, repeat S2, perform the working position switching through the rotating beam rotating cylinder 6, and start a new operation cycle.

[0068] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features.
