Description

Technical Field

[0001] The present invention relates to the technical field of tunnel equipment, and in particular to a rotating working mechanism and method of an anchor-grouting integrated machine. Background Art

[0002] In tunnel construction and underground engineering construction, anchor grouting trolleys, as important operating equipment, are widely used in multiple construction tasks such as drilling, installing anchor rods, and grouting. However, in the prior art, the design of anchor grouting trolleys has many shortcomings, which affect the operating efficiency and the simplicity of the construction process. Most traditional anchor grouting trolleys adopt a single workstation design, and the switching between each workstation needs to be achieved through cumbersome manual operations or through 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, which makes it difficult to meet the needs of efficient operations in complex projects.

[0003] The problem of station switching in traditional equipment is also reflected in the imperfection of the rotating structure. In the prior art, the rotating mechanism of the equipment is usually simple in structure and cannot achieve fast switching of multiple stations. This limitation not only causes the equipment to occupy a large construction space, but also easily affects the construction accuracy due to structural shaking, especially in high-intensity construction scenarios, making it difficult to meet the needs of fast, efficient, and continuous construction.

[0004] To this end, those skilled in the art provide a rotating working mechanism and method for an anchor-injection machine to solve the problems raised in the above background technology. Summary of the invention

DETAILED DESCRIPTION

[0039] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Embodiment 1:

[0041] The embodiment of the present invention provides a rotary working mechanism of an anchor injection machine, comprising:

[0042] Please refer to the attached Figure 1 -Attached Figure 3 , a rotating base 1, a total of multiple groups are installed on both sides of the vehicle body, used to support the rotating frame 3 and realize the basic support of the entire rotating mechanism; the rotating base 1 is connected to the rotating shaft 2 through a bearing 14, and the bearing 14 includes a combination structure of a ball bearing and a thrust bearing, which is used to support the relative rotational movement between the rotating base 1 and the rotating shaft 2.

[0043] Specifically, the rotating base 1 is composed of multiple groups, which are respectively installed on both sides of the vehicle body, forming the basic support structure of the entire rotating working mechanism. Each group of rotating bases 1 is connected to the rotating shaft 2 through bearings 14 to ensure that the rotating frame 3 can achieve precise rotation operation on the basis of the stability of the vehicle body. The design of the rotating base 1 fully considers the needs of the anchor trolley in different working environments, and its stable supporting function provides a solid foundation for the rotating mechanism. In order to ensure the stability during the rotation process and the durability of long-term use, the support bearing 14 of the rotating base 1 adopts a combination structure of ball bearings and thrust bearings. This combined structure can effectively reduce the friction between the rotating shaft 2 and the rotating base 1, and bear radial and axial loads at the same time, so as to maintain the smooth rotation of the rotating frame 3 in actual operation and improve the working efficiency of the entire mechanism.

[0044] 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 motion, ensuring that the rotating frame 3 can still maintain good rotation performance when working under heavy load or high pressure. The thrust bearing is specifically used to bear the axial load of the rotating shaft 2. Especially when the anchor grouting trolley performs high-intensity drilling operations, the thrust bearing can effectively resist the axial stress caused by the pressure changes of the equipment. Through this double protection, the relative rotational motion between the rotating base 1 and the rotating shaft 2 is precisely controlled, avoiding equipment wear or performance degradation caused by uneven load or excessive friction.

[0045] In addition, the multiple-group design of the rotating base 1 not only improves 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 anchoring and grouting trolley, ensuring that the rotating frame 3 can smoothly complete the switching of various workstations in narrow tunnel spaces or complex construction environments.

[0046] Please refer to the attached Figure 4 , the rotating shaft 2 is fixedly connected to the rotating base 1 through a connecting key 13, and is used to drive the rotating frame 3 to rotate;

[0047] Specifically, the rotating shaft 2 is fixedly connected to the rotating base 1 through the connecting key 13, and its main function is to drive the rotating frame 3 to rotate. As one of the core components of the rotating working mechanism of the entire anchoring trolley, the rotating shaft 2 bears the weight and movement requirements of the rotating frame 3 and its affiliated working mechanisms. The design of the connecting key 13 ensures a stable connection between the rotating shaft 2 and the rotating base 1, avoiding looseness or displacement during the rotation process, thereby ensuring the smooth switching of the rotating frame 3 between various workstations.

[0048] The rotating shaft 2 not only supports the rotating frame 3, but also ensures smoothness and accuracy during the rotation process. Through the precise cooperation of the connecting key 13, the rotating shaft 2 can effectively transmit the rotating power under the support of the rotating base 1, so that the rotating frame 3 can achieve precise angle adjustment. Whether it is drilling, anchor bolt installation, or other operations, the rotating shaft 2 can maintain stable rotational motion in different working positions and ensure coordinated operation with other working components.

[0049] 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 anchor mechanism it carries. Through the connecting key 13, the tight connection between the rotating shaft 2 and the rotating base 1 effectively prevents torsion or separation under high loads, further improving 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.

[0050] Please refer to the attached Figure 4 , a rotating frame 3 is used to carry the rock drilling mechanism assembly 8, the anchor mechanism assembly 9 and the air duct assembly 10, and realize the station switching through the rotating shaft 2;

[0051] The tightening oil cylinder 4 is hinged to the rotating frame 3, and the tightening oil cylinder maintains a tightening state with the wall during operation; the tightening oil cylinder 4 is hinged to the rotating frame 3, and its setting position is the front end of the rotating frame 3. The tightening oil cylinder 4 and the rotating frame 3 work together to maintain a stable support between the wall and the rock drilling mechanism assembly 8. The rock drilling mechanism assembly 8 is installed on the inner side of the rotating frame 3 through a sliding connection. The rock drilling mechanism assembly 8 includes a propulsion beam and a propulsion oil cylinder, which is driven by a compensation oil cylinder to achieve forward and backward movement during rock drilling operation.

[0052] Specifically, the jacking cylinder 4 is connected to the rotating frame 3 through an articulated structure and is located at the front end of the rotating frame 3. The function of the jacking cylinder 4 is to maintain close contact with the tunnel wall during operation, thereby providing stable support for the entire anchoring trolley. Due to its articulated design with the rotating frame 3, the jacking cylinder 4 can maintain independent movement during the rotation or angle adjustment of the rotating frame 3, ensuring stable contact with the wall at all times. This structural design allows the jacking cylinder 4 to reliably provide support force when the anchoring trolley is performing operations such as drilling and anchor bolt installation, even if the angle of the rotating frame 3 changes.

[0053] Please refer to the attached Figure 4 -Attached Figure 5The combined effect of the jacking cylinder 4 and the rotating frame 3 not only maintains the overall stability of the equipment, but also effectively offsets the reaction force that may be generated during operation through this precise articulated position distribution. Especially in high-pressure drilling or complex operating environments, the presence of the jacking cylinder 4 can ensure that the rotating frame 3 will not be displaced or swing unnecessarily when subjected to external impact or vibration, thereby maintaining the operating accuracy and safety of the equipment.

[0054] At the same time, the rock drilling mechanism assembly 8 is installed on the inner side of the rotating frame 3 by means of sliding connection. The rock drilling mechanism assembly 8 is composed of a propulsion beam and a propulsion cylinder. During the operation, the propulsion cylinder drives the rock drilling mechanism to move forward and backward through the compensation cylinder to complete the drilling task. The design of the compensation cylinder can fine-tune the rock drilling mechanism in 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.

[0055] The encoder 5 is installed at the rear end of the rotating shaft 2 and is used to monitor the swing angle of the rotating frame 3 in real time. The encoder 5 is connected to the rotating shaft 2 and is used to measure the swing angle of the rotating frame 3 in real time. The data feedback of the encoder 5 controls the start and stop of the propulsion beam rotating cylinder 6 to ensure that the rotating frame 3 is switched to the correct work position.

[0056] Please refer to the attached Figure 6 , the propulsion beam rotation cylinder 6 is connected to the rotating base 1 and the rotating frame 3, and is used to push the rotating frame 3 to switch between different workstations; the copper sleeve 7 is arranged between the rotating shaft 2 and the rotating frame 3, and is used to reduce the friction during rotation; the rod changing gripper 11, the rod changing gripper 11 is arranged on one side of the anchor rod bin assembly 15.

[0057] Specifically, as a key executive component of the rotation system, the propulsion beam rotation cylinder 6 is driven by hydraulic pressure to achieve precise movement of the rotation frame 3, so that each working component of the anchoring trolley is accurately switched to the corresponding position. Whether it is drilling operation or anchor installation, the power transmission of the rotation action is achieved through the propulsion beam rotation cylinder 6. The setting of the cylinder enables the rotation frame 3 to switch between multiple positions at a controllable speed and in a stable manner, ensuring the efficient operation of the equipment in various working environments.

[0058] The copper sleeve 7 is arranged between the rotating shaft 2 and the rotating frame 3. As an important supporting and lubricating element, the main function of the copper sleeve 7 is to reduce the friction 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 the direct contact of the metal can be effectively reduced, and the flexibility and durability of the rotating system can also be improved. The high wear resistance and low friction coefficient of the copper material enable it to extend the service life of the equipment and reduce the maintenance requirements when it bears the load 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.

[0059] Please refer to the attached Figure 5 The anchor rod mechanism assembly 9 is installed on the outside of the rotating frame 3 through a sliding connection. The anchor rod mechanism assembly includes a compensation cylinder, a propulsion beam, a propulsion cylinder, a front tightening device, a propeller center 12, a front pulley assembly, a rear pulley assembly and an anchor rod bin assembly 15, wherein the propulsion cylinder is used to push the anchor rod for installation and fixation.

[0060] The air duct assembly 10 is installed between the rotating frame 3 and the rock drilling mechanism assembly 8. The air duct assembly can be moved forward and backward by the extension and contraction of the oil cylinder. The connection of the air duct is coaxially arranged with the rock drilling mechanism assembly 8.

[0061] Please refer to the attached Figure 5 -Attached Figure 6 The rod changing gripper 11 grabs the anchor rod and pushes it to the thruster center 12. The rod changing gripper 11 swings through the mechanical arm and moves from the anchor rod bin assembly 15 to the thruster center 12. The rod changing gripper 11 is also used to support the anchor rod. The gripper and the thruster center 12 work in coordination. When the anchor rod moves to the thruster center 12, the rod changing gripper 11 automatically resets to the original position and waits for the next grab.

[0062] Specifically, the operation process relies on the swing control of the mechanical arm. After the rod-changing gripper 11 grabs the anchor from the anchor bin assembly 15, it moves along the set path and transports the anchor to the working position of the thruster center 12. The precise control of the mechanical arm ensures that the swing process of the gripper is stable and controllable, ensuring the smooth transportation of the anchor between various workstations. Through this grabbing and transportation process, the rod-changing gripper 11 effectively supports the anchor installation operation of the anchor grouting trolley and realizes automated operation.

[0063] The rod-changing gripper 11 is not only responsible for grabbing and conveying the anchor rod, but also assumes the function of supporting the anchor rod. In the process of the anchor rod moving from the anchor rod bin assembly 15 to the thruster center 12, the gripper firmly supports the anchor rod to prevent shaking or displacement during movement or swinging. The gripper works in coordination with the thruster center 12. When the anchor rod is successfully moved to the thruster center 12, the thruster takes over the subsequent installation of the anchor rod, and the rod-changing gripper 11 will automatically reset. The automatic reset function of the gripper enables it to return to its initial position immediately after completing a grabbing task, preparing for the next anchor rod grabbing operation.

Move the anchoring trolley to the construction site, 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 the tightening cylinder 4 is in contact with the tunnel wall to complete the tightening operation;

[0067] S2, start the propulsion beam rotating cylinder 6, so that the rotating frame 3 rotates around the rotating shaft 2, switches to the predetermined position, the encoder 5 monitors the swing angle of the rotating frame 3 and controls the propulsion beam rotating cylinder 6 to stop, and the copper sleeve 7 is located between the rotating shaft 2 and the rotating frame 3 to assist the rotation process;

[0068] S3, after the rotating frame 3 is switched to the drilling position, the rock drilling mechanism assembly 8 is started, the drilling operation is completed by the propulsion beam and the propulsion cylinder, and the position of the drill bit is adjusted by the compensation cylinder;

[0069] S4, after the rotating frame 3 is switched to the anchor bolt installation station, the anchor bolt mechanism assembly 9 is started, which includes a propulsion beam, a propulsion cylinder, a front tightening device and a propeller center 12, to complete the installation operation of the anchor bolt, and the anchor bolt library rotating mechanism 15 rotates the anchor bolt to the installation angle;

[0070] S5, start the rod changing gripper 11, grab the anchor rod from the anchor rod library rotation mechanism 15, move it to the position of the thruster center 12, and the rod changing gripper 11 automatically resets after the thruster completes the anchor rod operation;

[0071] S6. Use the air duct assembly 10 to provide airflow. The air duct assembly 10 moves forward and backward through the extension of the oil cylinder and keeps coaxial with the rock drilling mechanism assembly 8;

[0072] S7. After completing one drilling and anchor bolt installation operation, repeat S2, and switch the workstation by pushing the beam rotating cylinder 6 to start a new operation cycle.

[0073] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
