Description

Technical Field

[0001] This utility model belongs to the technical field of tunnel construction equipment, and in particular relates to an integrated tunnel construction machine. Background Technology

[0002] During tunnel construction, the integrated machine is large and heavy, making a supporting base essential to ensure its safety and stability. Currently, the support structure for traditional integrated machines and other large construction equipment typically uses a vertical telescopic support base. However, during arch frame installation, the support base or the machine body may collide with the arch frame, causing equipment damage. Furthermore, in some cases, uneven ground can lead to unstable support and a risk of tipping over. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model discloses an integrated tunnel construction machine that can adapt to the arch frame model carried by the machine body by adjusting the rotation angle and / or lateral movement distance of the support base relative to the machine body according to the actual construction situation. While ensuring support stability, it avoids collisions between the support base and the arch frame during construction.

[0004] The specific technical solution of this utility model is as follows:

[0005] A tunnel construction integrated machine, comprising:

[0006] The machine body is provided with multiple telescopic columns, and the free end of each telescopic column is connected to a rotary mechanism.

[0007] The support base and the rotary mechanism are connected via a lateral movement mechanism; and

[0008] The power source is used to drive the support base to move laterally relative to the machine body;

[0009] The rotary mechanism adjusts the relative angle between the support base and the machine body to adjust the support position of the support base.

[0010] In some existing technologies, the machine body can be moved synchronously by laterally shifting the support base to move it to the appropriate position before arch frame installation. While this reduces the risk of collision between the support base and the arch frame, collisions can still occur with longer arch frames. This not only affects arch frame transportation but also fails to provide sufficient working space during arch erection. If the lateral shift distance of the support base is increased to accommodate longer arch frames, the center of gravity of the support base may become unbalanced, leading to instability in the support structure and seriously affecting the safety and stability of construction. Therefore, this application provides a slewing mechanism that allows the support base to rotate relative to the machine body. In cases of long arch frames or insufficient installation space, the rotation of the support base can be controlled by the slewing mechanism to adjust the support position. This facilitates arch frame transportation while avoiding collisions between the arch frame and the support base during operation. This not only avoids construction difficulties caused by insufficient space and improves operational convenience but also effectively enhances operational safety.

[0011] Preferred options also include:

[0012] A transition frame is provided between the traversing mechanism and the rotary mechanism.

[0013] Since the transition frame can be regarded as part of the transverse or slewing mechanism, it can reduce the overall weight of the transverse or slewing mechanism during installation, thereby reducing safety hazards. Based on this, it can effectively reduce assembly precision and simplify the installation process.

[0014] Preferably, the lateral movement mechanism includes a slide rail, and the slide rail and the transition frame are slidably engaged;

[0015] The slide rail is mounted on the support base.

[0016] The structure is simple and easy to implement, and it can effectively enable the lateral sliding of the support base relative to the machine body.

[0017] Preferably, the power source is a transverse telescopic cylinder, and the two ends of the transverse telescopic cylinder are respectively connected to a support base and a transition frame.

[0018] This structure is simple and practical, easy to install and use, and can effectively drive the support base laterally.

[0019] Preferably, the rotary mechanism includes:

[0020] A slewing seat, one side of which is connected to a telescopic column, and the other side of which is connected to a transition frame; and

[0021] A rotary reducer is connected to a rotary base and is used to drive the transition frame to rotate circumferentially along the central axis of the rotary base.

[0022] This structure is simple and practical, easy to install and use, and can effectively enable the rotation of the transition frame relative to the machine body, thereby enabling the support base to rotate relative to the machine body.

[0023] Preferably, the telescopic column includes:

[0024] Column 1 and Column 2, wherein Column 1 is a hollow structure and Column 2 is located inside Column 1;

[0025] Among them, one of the columns is connected to the machine body and the other is connected to the rotating mechanism. A telescopic mechanism is provided between the columns.

[0026] This structure is simple and practical, easy to install and use, and can effectively support the machine body with the support base.

[0027] Preferably, the first column and the second column are in a sliding fit.

[0028] This structure has high stability and can effectively increase the volume of column two while avoiding movement interference between column one and column two, thereby further increasing the support stability of the support base.

[0029] Preferably, the machine body is provided with multiple working platforms, and each working platform is provided with a ladder.

[0030] Multi-level work platforms can provide workers with different work areas, thereby enabling accurate division of labor and improving tunnel construction efficiency. The ladders facilitate workers' movement from the ground to different work platforms and have advantages such as simple structure, easy use, small footprint, and light weight.

[0031] Preferably, a crane is installed on the top working platform to lift the arch frame.

[0032] The crane is located on the highest working platform, which has a height advantage, thus enabling better transfer of the arch frame and effectively ensuring construction efficiency.

[0033] Preferably, a robotic arm is installed on the top working platform;

[0034] The robotic arm includes:

[0035] A connecting arm, one end of which is connected to the machine body;

[0036] The gripper mechanism is located at the end of the connecting boom furthest from the machine body; and

[0037] The shotcrete mechanism is configured to be located at the end of the connecting boom away from the machine body via a rotary mechanism 2, so as to switch between the recovery position and the working position;

[0038] When the shotcrete mechanism is in the recovery position, the gripper mechanism is used to grab the arch frame;

[0039] When the shotcrete mechanism is in the working position, shotcrete operations are performed using the shotcrete mechanism.

[0040] In this application, both the gripper mechanism and the shotcrete mechanism are mounted on the connecting boom. The shotcrete mechanism is connected to the connecting boom via a second slewing mechanism. Therefore, when only the second slewing mechanism is driven, only the shotcrete mechanism moves relative to the connecting boom. This allows for switching between the arch frame function and the shotcrete function. In other words, when the shotcrete mechanism is in the working position, the gripper mechanism is unusable. When the shotcrete mechanism is in the retraction position, it can avoid the gripper mechanism, allowing for normal use. Thus, configuring both the gripper mechanism and the shotcrete mechanism on the same robotic arm effectively reduces the number of robotic arms required for separate integration of the gripper mechanism and the shotcrete mechanism, thereby avoiding the problem of insufficient construction space caused by multiple robotic arms existing simultaneously. Furthermore, the second slewing mechanism is easy to operate, thus improving construction quality and efficiency.

[0041] Compared with the prior art, the support base provided by this utility model has lateral movement and rotation capabilities, which allows the support base to slide flexibly laterally and rotate to a suitable position during tunnel construction, avoiding collision with the arch frame, ensuring sufficient construction space, and avoiding imbalance of the center of gravity while maintaining stability, thus achieving safe and efficient construction support.

Detailed Implementation

[0047] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to specific embodiments.

[0048] like Figures 1-2 As shown, a tunnel construction integrated machine includes a body 8, a support base 1, and a power source 2. The body 8 is provided with multiple telescopic columns, and the free ends of the telescopic columns are connected to a slewing mechanism 5. The support base 1 and the slewing mechanism 5 are connected by a lateral movement mechanism. The power source 2 is used to drive the support base 1 to move laterally relative to the body 8. The slewing mechanism 5 adjusts the relative angle between the support base 1 and the body 8 to adjust the support position of the support base 1.

[0049] In this embodiment, the machine body 8 is provided with multiple support seats 9, which are the main components supporting the machine body 8. The support base 1 serves as an auxiliary support component, which can well meet the operational requirements of any working condition, enabling the machine body 8 to obtain stable support capacity. Furthermore, it avoids imbalance caused by center of gravity shift during the hoisting of the arch frame, thereby better meeting the requirements of safe and efficient construction. The integrated machine also includes a transition frame 3, which is disposed between the transverse movement mechanism and the slewing mechanism 5.

[0050] Furthermore, the slewing mechanism 5 includes a slewing base and a slewing reducer; one side of the slewing base is connected to the telescopic column, and the other side is connected to the transition frame 3; the slewing reducer is connected to the slewing base and is used to drive the transition frame 3 to rotate circumferentially along the central axis of the slewing base. The transverse movement mechanism includes a slide rail 4, which is slidably engaged with the transition frame 3; the slide rail 4 is disposed on the support base 1. Thus, during construction, when arch frame installation or transportation is required, the transverse movement mechanism drives the support base 1 to move into the integrated unit, and the telescopic column extends to the ground to provide stable support for the machine body 8; for cases where the arch frame is long, if the arch frame contacts the support base 1 or affects the insufficient space for arch frame transportation and installation, the rotation angle of the support base 1 can be controlled by the slewing mechanism 5 to rotate the support base 1 to an appropriate position, ensuring sufficient space for arch frame installation and transportation, avoiding interference, and improving construction efficiency. Therefore, this embodiment, through the reasonable configuration of the lateral movement mechanism and the slewing mechanism 5, enables the support base 1 to have flexible adjustment capabilities during the construction of the integrated machine. This ensures the smooth transportation of the side arch and the erection of the arch, while also preventing collisions between the support base 1 and the arch frame, thus ensuring the safety and efficiency of the construction process. Specifically, in this embodiment, the slide rail 4 is set on the support base 1, and the slider is connected to the transition frame 3. Thus, when the slewing mechanism 5 operates, it carries and rotates the support base 1 through the transition frame 3 to meet actual usage requirements. It can be seen that the actions of the slewing mechanism 5 and the lateral movement mechanism do not interfere with each other and have independent operation. However, in the case of an excessively long arch frame, the slewing mechanism 5 and the lateral movement mechanism also have synergy. That is, the joint action of the slewing mechanism 5 and the lateral movement mechanism is based on the actual length of the arch frame. When needed, the slewing mechanism 5 and the lateral movement mechanism can be driven simultaneously to better avoid the arch frame. Furthermore, when used in conjunction with telescopic columns, they can also meet the support requirements at the corresponding positions. Therefore, this embodiment solves the problems of traditional support base 1 easily colliding with the arch frame and insufficient space during use, providing a safer, more efficient and flexible support solution for tunnel construction.

[0051] like Figure 3 As shown, in some other embodiments, the lateral movement mechanism includes a slide rail 4 and a plurality of sliding members 16 arranged in a straight line, wherein the sliding members 16 and the slide rail 4 are slidably engaged. In the support base 1 and the transition frame 3, one is provided with the slide rail 4 and the other is provided with the sliding member 16. This structure is relatively complex compared to this embodiment. The engagement of the sliding member 16 and the slide rail 4 can not only achieve mutual sliding, but also support the support base 1 using the slide rail 4 and the sliding member 16, so that the support base 1 is stably and reliably connected to the rotary mechanism 5. It can be seen that, similarly, in this embodiment, the slide rail 4 and the transition frame 3 can also be used to support the support base 1.

[0052] In this embodiment, the power source 2 is a transverse telescopic cylinder, and the two ends of the transverse telescopic cylinder are respectively connected to the support base 1 and the transition frame 3. Specifically, in order to ensure the stability of the transverse telescopic cylinder's movement, the two ends of the transverse telescopic cylinder are respectively hinged to the support base 1 and the transition frame 3, so that even if vibration occurs or the assembly precision is not high, a stable transverse movement function can still be achieved.

[0053] In this embodiment, the telescopic column includes a first column 7 and a second column 6. The first column 7 has a hollow structure, and the second column 6 is disposed inside the first column 7. One of the first column 7 and the second column 6 is connected to the body 8, and the other is connected to the rotating mechanism 5. A telescopic mechanism is provided between the first column 7 and the second column 6. Furthermore, the first column 7 and the second column 6 are slidably fitted together. In this embodiment, the first column 7 is connected to the body 8, the second column 6 is connected to the rotating mechanism 5, and the telescopic mechanism is a column telescopic cylinder. When the column telescopic cylinder is activated, column 2 (6) moves up and down relative to column 1 (7). If there is a gap between column 1 (7) and column 2 (6), the movement of column 2 (6) can cause it to swing relative to column 1 (7), potentially colliding with it and creating a safety hazard. Furthermore, it can prevent the bottom surface of the support base 1 from fully contacting the ground, reducing support stability. Therefore, in this embodiment, column 1 (7) and column 2 (6) are configured in a sliding fit relationship, with column 2 (6) limited in its circumferential direction, allowing it to move up and down only along a preset path, thus ensuring support stability. The sliding fit between column 1 (7) and column 2 (6) can be achieved through a sliding groove roller structure or a sliding rail 4 slider structure, etc.

[0054] In this embodiment, the machine body 8 is provided with multiple working platforms, and each working platform is equipped with a ladder. This embodiment includes a first working platform 10 and a second working platform 12. The first working platform 10 is located above the second working platform 12. The first working platform 10 is equipped with a first ladder 11, and the second working platform 12 is equipped with a second ladder 13. Thus, workers can climb from the ground to the first working platform 10 via the first ladder 11, and climb from the first working platform 10 to the second working platform 12 via the second ladder 13. This structure is simple and easy to implement. Furthermore, a crane 14 is provided on the top working platform for lifting the arch frame. Specifically, the second working platform 12 is equipped with a crane 14. It is known that a workpiece placement section 15 is provided on the machine body 8. In this embodiment, the crane 14 is used to lift the arch frame to place it in the workpiece placement section 15 or to remove the arch frame from the workpiece placement section. Workers can hook the hook of the crane 14 onto the arch frame from the second working platform 12 to achieve the transfer of the arch frame. It should be noted that the workpiece placement part 15 in this embodiment is rotatable to adapt to the length of the arch frame.

[0055] like Figure 1 and Figure 4 As shown, in this embodiment, a robotic arm is provided on the top working platform; the robotic arm includes a connecting arm 16, a gripper mechanism 17, and a shotcrete mechanism 18. In this embodiment, the top working platform (second working platform 12) is also provided with a track and a moving block that slides with the track. One end of the connecting arm 16 is connected to the moving block; the gripper mechanism 17 is located at the end of the connecting arm 16 away from the moving block; the shotcrete mechanism 18 is located at the end of the connecting arm 16 away from the moving block via a rotary mechanism 19, so as to switch between a recovery position and a working position; when the shotcrete mechanism 18 is in the recovery position, the gripper mechanism 17 is used to grip the arch frame; when the shotcrete mechanism 18 is in the working position, the shotcrete mechanism 18 is used to perform shotcrete operations.

[0056] In this embodiment, both the gripper mechanism 17 and the shotcrete mechanism 18 are located at the end of the connecting boom 16, thus maximizing the construction distance. In this embodiment, to minimize interference between the gripper mechanism 17 and the shotcrete mechanism 18 during construction, the shotcrete mechanism 18 and the connecting boom 16 are positioned in the same plane, regardless of whether the shotcrete mechanism 18 is in the recovery position or the working position. That is, the relative angle between the shotcrete mechanism 18 and the connecting boom 16 is 0° or 180°. Figure 4 As shown, when the gripper mechanism 17 is in its initial position, the relative angle between the overall structure of the gripper mechanism 17 and the connecting boom 16 is 180°. At this time, when the shotcrete mechanism 18 is in its working position, the shotcrete mechanism 18 is directly above the gripper mechanism 17, and the shotcrete mechanism 18, gripper mechanism 17, and connecting boom 16 are all in the same plane. When the shotcrete mechanism 18 is in its retracted position, the shotcrete mechanism 18 is also directly above the connecting boom 16, and the shotcrete mechanism 18, gripper mechanism 17, and connecting boom 16 are still in the same plane. In other words, when the shotcrete mechanism 18 is in its working position, it effectively conceals the gripper mechanism 17, while when it is in its retracted position, it exposes the gripper mechanism 17, allowing it to operate normally. Clearly, when the overall structural length of the shotcrete mechanism 18 is greater than that of the gripper mechanism 17, it better meets the actual usage requirements.

[0057] Therefore, this embodiment can improve the flexibility and stability of the support body 8. Specifically, by setting a lateral movement mechanism, the support base 1 can be moved laterally relative to the body 8, allowing the support base 1 to be adjusted in position as needed during construction. This effectively avoids collisions between the arch frame and the support base 1, thereby reducing equipment damage and ensuring construction safety and stability. This embodiment can enhance space utilization. Based on the use of the rotation mechanism 5, when encountering situations where the arch frame is long or installation space is insufficient, the rotation mechanism 5 can control the rotation of the support base 1 to adjust the support position, providing more space for the installation and transportation of the arch frame, avoiding construction difficulties caused by insufficient space, and improving operational convenience. This embodiment can reduce equipment failures and maintenance needs. Through the coordinated application of the lateral movement mechanism and the rotation mechanism 5, the support base 1 can be automatically adjusted under different operational requirements, reducing the probability of failures caused by support imbalance, thereby reducing the frequency of manual adjustment and maintenance and improving construction efficiency. This embodiment can improve construction efficiency. It can quickly adjust the support base 1 to a suitable position, reducing obstacles during the installation and transportation of the arch frame and the time required for equipment repositioning, thus significantly improving the smoothness and efficiency of the construction process.

[0058] The above are merely preferred embodiments of this utility model. It should be noted that the above preferred embodiments should not be considered as limitations on this utility model, and the scope of protection of this utility model should be determined by the scope defined in the claims. For those skilled in the art, several improvements and modifications can be made without departing from the spirit and scope of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
