Description

Technical Field

[0001] This utility model relates to the field of pipeline installation technology, and more specifically, to an auxiliary installation device for tunnel ventilation pipes. Background Technology

[0002] Tunnels are engineering structures that penetrate mountains, water bodies, or underground cities. Tunnel ventilation ducts are a key component of tunnel ventilation systems, delivering fresh air and expelling harmful gases (such as carbon monoxide and nitrogen oxides) and dust from vehicle exhaust. They are crucial for ensuring tunnel air quality, driving safety, and the health of personnel. Therefore, when installing tunnel ventilation ducts, auxiliary installation devices are necessary to improve installation efficiency and stability.

[0003] For example, the patent document with application number CN220703039U includes a base, four heavy-duty casters are installed on the lower surface of the base, four support frames are installed on the upper surface of the base, a carrier is slidably installed between the four support frames, multiple hydraulic lifting columns are installed between the carrier and the base, and a standing platform is fixedly installed on the outer surface of the carrier.

[0004] While existing auxiliary installation devices can assist in the installation of ventilation pipes in tunnels and improve installation efficiency, they also suffer from the problem of pipe swaying during the lifting and transport process. This swaying can damage the auxiliary installation device, threaten the safety of workers, and ultimately affect installation efficiency and endanger personal safety.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0006] In view of the problems in the related technologies, this utility model proposes an auxiliary installation device for tunnel ventilation pipes to overcome the above-mentioned technical problems existing in the existing related technologies.

[0007] Therefore, the specific technical solution adopted by this utility model is as follows:

[0008] A tunnel ventilation duct auxiliary installation device includes a base; support frames symmetrically disposed on the top of the base; mounting frames disposed on the common top of two sets of support frames; a fence disposed on both sides of the mounting frames; a hanging mechanism disposed at both ends of the mounting frames; a placement frame disposed on the top of the base and cooperating with the hanging mechanism; hydraulic lifting columns symmetrically disposed on both sides of the base and connected to the bottom of the fence; protective ladders installed at both ends of the fence; a fixing mechanism disposed inside the placement frame; a support assembly sleeved on the outside of the support frames and located on the top of the base; and a control panel disposed on one side of the base.

[0009] Furthermore, to ensure the smooth lifting and movement of the suspension mechanism, two sets of end blocks are symmetrically arranged on both sides of the placement frame, and guide rods are installed on the end blocks; hanging rings are symmetrically arranged at both ends of the placement frame, and baffles are installed inside the placement frame.

[0010] Furthermore, to enable rapid fixing or disassembly of the placement frame and avoid problems such as tilting or swaying of the ventilation pipe due to uneven lifting force, the hanging mechanism includes support blocks symmetrically arranged at one end of the mounting frame. A drive shaft is inserted through the support block, and a steel wire rope is sleeved on one end of the outer circumference of the drive shaft. A connecting block is fixedly installed at the connecting end of the steel wire rope, and a fixing post is sleeved on the connecting block. A snap-fit ​​post is provided at the bottom of one end of the fixing post; a T-shaped block is provided at the top of one end of the snap-fit ​​post, and a fixing plate is provided at the top of the other end of the snap-fit ​​post, with a lifting ring groove in the middle of the snap-fit ​​post; a mounting plate is provided at the bottom of the other end of the fixing post, with a mounting groove on one side that mates with the fixing plate; an insert is provided inside the mounting plate that penetrates the fixing plate; a fixing groove that mates with the insert is provided at one end of the mounting plate; and a servo motor is connected to one end of the drive shaft through the support block. The fixing post has a U-shaped structure, with a T-shaped slot that mates with the T-shaped block inside one end of the fixing post. The cross-sectional area of ​​the lifting ring groove is the same as the width of the hanging ring, and the lifting ring groove and the hanging ring are matched.

[0011] Furthermore, to effectively limit the free movement of the ventilation duct during lifting and transportation, reduce the amplitude of swaying, and avoid impact and damage to the device due to excessive swaying, the fixing mechanism includes two sets of slide rails symmetrically arranged at the top of the placement frame. A sliding plate is mounted at the top of each slide rail, and a connecting rod is mounted at the top of each sliding plate. The two sets of connecting rods are connected to a turntable via connecting rods, and the turntable is mounted on the top of the placement frame via a connecting plate. Several linearly arranged support rods are mounted at the top of the sliding plate, and a clamping plate is mounted on the top of each support rod. Several anti-slip blocks are arranged in an equidistant linear direction on the clamping plate. Hydraulic rods are symmetrically arranged on one side of the sliding plate and are mounted on the top of the placement frame. Movable grooves that cooperate with the support rods are provided on the baffle plate.

[0012] Furthermore, to prevent swaying or tilting and ensure the structural stability of the entire auxiliary installation device, the support assembly includes a fixed shell fitted onto the outside of the support frame. A base plate is provided around the outer perimeter of the fixed shell, and fixing blocks with a triangular structure are provided on the base plate. The base plate is connected to the base via bolts.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By setting up a hanging mechanism, the hanging mechanism can evenly bear the weight of the ventilation pipe inside the placement frame and provide a stable lifting force during the lifting process. With the cooperation of the insert and lifting ring groove with the placement frame, the ventilation pipe inside the placement frame remains stable during the rise. At the same time, it can quickly complete the fixing or disassembly of the placement frame and avoid problems such as tilting and shaking of the ventilation pipe caused by uneven lifting force.

[0015] 2. With the addition of a fixing mechanism, the ventilation pipe can be precisely positioned and clamped during the process of cooperating with the hanging mechanism, and the ventilation pipe can be firmly fixed in the position of the placement frame. This effectively restricts the free movement space of the ventilation pipe during the lifting and transportation process, reduces the amplitude of the ventilation pipe swaying, and avoids impact and damage to the device due to excessive swaying.

[0016] 3. By setting up a support component, which is fixed on the base and located on the support frame, it maintains a stable upright state when bearing the weight of the ventilation pipe and other external forces, preventing it from shaking or tilting, thereby ensuring the structural stability of the entire auxiliary installation device.

[0028] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0029] According to an embodiment of the present invention, an auxiliary installation device for tunnel ventilation pipes is provided.

[0030] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-8As shown, an auxiliary installation device for tunnel ventilation pipes according to an embodiment of the present invention includes a base 1; a support frame 2 symmetrically disposed on the top of the base 1; an installation frame 3 disposed on the common top of the two sets of support frames 2; a fence 4 disposed on both sides of the installation frame 3; a hanging mechanism 5 disposed at both ends of the installation frame 3; a placement frame 6 disposed on the top of the base 1 and cooperating with the hanging mechanism 5; a hydraulic lifting column 7 symmetrically disposed on both sides of the base 1 and connected to the bottom of the fence 4; a protective ladder 8 installed at both ends of the fence 4; a fixing mechanism 9 disposed inside the placement frame 6; a support component 10 sleeved on the outside of the support frame 2 and located on the top of the base 1; and a control panel 11 disposed on one side of the base 1.

[0031] By incorporating the aforementioned technical solution of this utility model, a hanging mechanism 5 is provided, which enables the hanging mechanism 5 to evenly bear the weight of the ventilation pipe inside the placement frame 6 and provide a stable lifting force during the lifting process. Furthermore, the cooperation of the insert and lifting ring groove with the placement frame 6 ensures that the ventilation pipe inside the placement frame 6 remains stable during ascent. Simultaneously, it allows for quick fixing or disassembly of the placement frame 6, avoiding problems such as tilting and swaying of the ventilation pipe caused by uneven lifting force. The fixing mechanism 9, in conjunction with the hanging mechanism 5, can accurately position and clamp the ventilation pipe, firmly fixing it to the position of the placement frame 6. This effectively restricts the free movement of the ventilation pipe during lifting and transportation, reducing the amplitude of swaying and preventing impact and damage to the device due to excessive swaying.

[0032] Furthermore, in practical applications, a control panel 11 is installed on one side of the base 1. This control panel 11 is electrically connected to the two sets of suspension mechanisms 5, the four hydraulic lifting columns 7, and the fixing mechanism 9. Operators can input relevant data through the human-machine interface of the control panel 11, thereby enabling the two sets of suspension mechanisms 5, the four hydraulic lifting columns 7, and the fixing mechanism 9 to sequentially deploy, fix, and lift during the process of raising the ventilation pipe.

[0033] Furthermore, the control panel 11 is equipped with a human-machine interface and a PLC programmable logic controller. The human-machine interface is the interaction interface between the operator and the automation system. Its main function is to display the real-time operating status and the input of control commands. The PLC is used to execute specific control tasks, such as switching, controlling speed, or sensor signal acquisition and processing.

[0034] In one embodiment, for the aforementioned placement frame 6, two sets of end blocks 12 are symmetrically arranged on both sides of the placement frame 6, and guide rods 13 are provided on the end blocks 12; hanging rings 14 are symmetrically arranged at both ends of the placement frame 6, and baffles 15 are provided inside the placement frame 6, so that the hanging mechanism 5 can be lifted and moved smoothly.

[0035] In one embodiment, the suspension mechanism 5 includes support blocks 501 symmetrically arranged at one end of the mounting frame 3. A drive shaft 502 is inserted through the support block 501. A steel wire rope 503 is sleeved on one end of the outer circumference of the drive shaft 502. A connecting block 504 is fixedly installed at the connecting end of the steel wire rope 503. A fixing post 505 is sleeved on the connecting block 504. A snap-fit ​​post 506 is provided at the bottom of one end of the fixing post 505. A T-shaped block 507 is provided at the top of one end of the snap-fit ​​post 506 for snap-fitting. A fixing plate 508 is provided at the top of the other end of the column 506, and a lifting ring groove 509 is provided in the middle of the column 506; a mounting plate 510 is provided at the bottom of the other end of the fixing column 505, and a mounting groove 511 that mates with the fixing plate 508 is provided on one side of the mounting plate 510; an insert 512 that penetrates the fixing plate 508 is provided inside the mounting plate 510; a fixing groove 513 that mates with the insert 512 is provided at one end of the mounting plate 510; a servo motor 514 is connected to one end of the drive shaft 502 that passes through the support block 501. The fixing column 505 has a U-shaped structure, and a T-shaped slot 515 that mates with the T-shaped block 507 is provided inside one end of the fixing column 505. The cross-sectional area of ​​the lifting ring groove 509 is the same as the width of the hanging ring 14. The lifting ring groove 509 mates with the hanging ring 14, thereby enabling quick fixing or disassembly of the placement frame and avoiding problems such as tilting or shaking of the ventilation pipe caused by uneven lifting force.

[0036] The working principle of the suspension mechanism 5: When the placement frame 6 needs to be lifted, the T-shaped block 507 on the locking post 506 engages with the T-shaped slot 515 on the fixing post 505 to prevent it from falling off during lifting. The fixing plate 508 is pushed into the mounting slot 511 of the mounting plate 510. Then, the insert 512 passes through the through holes of the mounting plate 510 and the fixing plate 508 in sequence, and engages downwards with the fixing slot 513 through the fixing slot 513 to prevent loosening. The hanging rings 14 at both ends of the placement frame 6 are embedded in the hanging ring slots 509 of the locking post 506 to prevent the placement frame 6 from tilting during lifting. The fixing post 505 is connected to the placement frame 6 and hanging rings 14 through the locking post 506 and the hanging ring slots 509. The load is transferred through the T-shaped slot 515 and the mounting plate 510 to the hanging ring slots 509 of the locking post 506, and finally borne by the wire rope 503.

[0037] After the connection is complete, the servo motor 514 is started using the human-machine interface of the control panel 11, driving the drive shaft 502 to rotate on the support block 501. A steel wire rope 503 is wound around the outer wall of the drive shaft 502. When the servo motor 514 rotates forward, the steel wire rope 503 gradually winds around the drive shaft 502, generating an upward pulling force. The end of the steel wire rope 503 is fixedly connected to the fixed column 505 via a connecting block 504. The tension of the steel wire rope 503 acts directly on the connecting block 504 and drives the fixed column 505, causing it to move upward. The connecting block 504 rises vertically under the tension of the steel wire rope 503. Furthermore, guide rods 13 are provided on the end blocks 12 on both sides of the placement frame 6 to prevent the placement frame 6 from shifting.

[0038] Meanwhile, the stability of the placement frame 6 is ensured during the lifting process thanks to the cooperation between the lifting ring groove 509 and the hanging ring 14. The human-machine interface of the control panel 11 controls the two sets of servo motors 514 to ensure that the winding and unwinding speeds of the steel wire ropes 503 on both sides are consistent during the driving process, preventing the placement frame 6 from tilting or jamming due to uneven force. Conversely, by controlling the two sets of servo motors 514 to reverse simultaneously via the human-machine interface of the control panel 11, the drive shaft 502 releases the steel wire ropes 503, and the placement frame 6 slowly descends under gravity. After the speed of the two sets of servo motors 514 gradually decreases, the plug 512 is pulled out, releasing the lock between the fixing plate 508 and the mounting plate 510. Then, the fixing plate 508 rotates to the right, separating the placement frame 6 from the fixing column 505.

[0039] In one embodiment, the fixing mechanism 9 includes two sets of slide rails 901 symmetrically arranged on the top of the placement frame 6. The top of the slide rails 901 is provided with a sliding plate 902, and the top of the sliding plate 902 is provided with a connecting rod 903. The two sets of connecting rods 903 are connected to the turntable 905 through connecting rods 904. The turntable 905 is installed on the top of the placement frame 6 through a connecting plate 906. The top of the sliding plate 902 is provided with a plurality of support rods 907 arranged in a linear pattern. The top of the plurality of support rods 907 is provided with a clamping plate 908. The clamping plate 908 is provided with a plurality of anti-slip blocks 909 arranged in an equidistant linear direction. A hydraulic rod 910 is symmetrically arranged on one side of the sliding plate 902 and is installed on the top of the placement frame 6. The baffle 15 has a movable groove 911 that cooperates with the support rod 907, thereby effectively restricting the free movement space of the ventilation pipe during the lifting and transportation process, reducing the amplitude of the ventilation pipe swaying, and avoiding impact and damage to the device due to excessive swaying.

[0040] Working principle of fixing mechanism 9: When it is necessary to fix the ventilation pipe inside the placement frame 6, the human-machine interface of the control panel 11 controls the activation of two hydraulic rods 910. The hydraulic rods 910 are installed on the top of the placement frame 6, and one end of the hydraulic rods 910 is connected to one side of the sliding plate 902. Then, when the hydraulic rods 910 extend or retract, the sliding plate 902 is placed on the top of the slide rail 901. The slide rail 901 guides the sliding plate 902, restricting its linear movement along the slide rail 901. Therefore, the extension or retraction of the hydraulic rods 910 will push or pull the sliding plate 902 to move along the slide rail 901. A connecting rod 903 is provided at the top of the sliding plate 902. Two sets of connecting rods 903 are connected to the turntable 905 through connecting rods 904. The turntable 905 is installed on the top of the placement frame 6 through connecting plate 906.

[0041] When the sliding plate 902 moves, it drives the connecting rod 903 to move, and the connecting rod 903 drives the turntable 905 to rotate via the connecting rod 904. The linear motion of the sliding plate 902 is converted into the rotational motion of the turntable 905 through the connecting rod 903 and the connecting rod 904. At the same time, the rotational motion of the turntable 905 stabilizes the motion of the connecting rod 903, ensuring that the clamping force of the clamping plate 908 on the ventilation pipe is evenly distributed. As the sliding plate 902 moves, the support rod 907 drives the clamping plate 908 to move synchronously. When the sliding plate 902 approaches the ventilation pipe under the extension and retraction of the hydraulic rod 910, the clamping plate 908 gradually approaches the surface of the ventilation pipe, clamping the ventilation pipe tightly.

[0042] In addition, the anti-slip block 909 increases the friction between the clamping plate 908 and the ventilation pipe, preventing the ventilation pipe from sliding or loosening during clamping. During the movement of the clamping plate 908, the support rod 907 slides within the movable groove 911. The movable groove 911 limits the movement of the support rod 907, preventing it from shifting during movement and ensuring that the clamping plate 908 moves accurately along a predetermined trajectory, achieving precise clamping of the ventilation pipe. Conversely, during the human-machine interface control of the control panel 11, the two hydraulic rods 910 are pushed, causing the sliding plate 902 to move away from the ventilation pipe under the pressure of the hydraulic rods 910, and the clamping plate 908 gradually moves away from the ventilation pipe, releasing it.

[0043] In one embodiment, the support assembly 10 includes a fixed shell 1001 sleeved on the outside of the support frame 2. A base plate 1002 is provided around the outer perimeter of the fixed shell 1001, and a fixing block 1003 is provided on the base plate 1002, with the fixing block 1003 having a triangular structure. The base plate 1002 is bolted to the base 1 to prevent it from shaking or tilting, thus ensuring the structural stability of the entire auxiliary installation device.

[0044] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0045] In practical applications, when installing ventilation pipes at the top of the tunnel, workers enter the enclosure 4 via the protective ladder 8 and then lift the ventilation pipes inside the placement frame 6 to the top of the tunnel for installation. When the ventilation pipes inside the placement frame 6 need to be fixed, the human-machine interface of the control panel 11 controls the two hydraulic rods 910 of the fixing mechanism 9. As the hydraulic rods 910 start to pull backward, they drive the sliding plate 902 to move along the slide rail 901, and the clamping plate 908 gradually approaches the surface of the ventilation pipe, clamping the ventilation pipe. Then, the human-machine interface of the control panel 11 controls the four sets of hydraulic lifting columns 7 to rise together. The output ends of the four sets of hydraulic lifting columns 7 cause the enclosure 4 to rise. After the enclosure 4 is raised to the elevation position at the top of the tunnel where the ventilation pipes are installed, the human-machine interface of the control panel 11 stops the rise of the four sets of hydraulic lifting columns 7.

[0046] Then, the insert 512 of the hanging mechanism 5 passes through the through holes of the mounting plate 510 and the fixing plate 508 in sequence, and the insert 512 is engaged with the fixing groove 513 downwards through the fixing groove 513. The hanging ring 14 of the placement frame 6 is embedded in the hanging ring groove 509 of the locking post 506 for locking and fixing. The human-machine interface of the control panel 11 controls the two sets of servo motors 514 to rotate forward simultaneously, driving the placement frame 6 to move upwards and lift the placement frame 6 to the bottom of the tunnel ventilation pipe installation. The human-machine interface of the control panel 11 controls the two sets of servo motors 514 to stop. During the lifting process, the guide rod 13 on the placement frame 6 can prevent swaying or tilting during the lifting.

[0047] Subsequently, the two hydraulic rods 910 of the fixing mechanism 9 are pushed by the human-machine interface of the control panel 11 again, so that the sliding plate 902 moves away from the ventilation pipe under the push of the hydraulic rods 910, and the clamping plate 908 gradually moves away from the ventilation pipe (the working principle of the fixing mechanism 9 is as described above). After the ventilation pipe is released, the staff takes out the ventilation pipe for installation.

[0048] In addition, when installing the ventilation duct, the two sets of servo motors 514 of the hanging mechanism 5 are simultaneously reversed using the human-machine interface of the control panel 11. The drive shaft 502 releases the steel wire rope 503, and the placement frame 6 slowly descends under the action of gravity (the working principle of the hanging mechanism 5 is as described above). When the placement frame 6 reaches the base 1, the staff puts the ventilation duct inside the placement frame 6 again. After fixing it with the fixing mechanism 9, the staff uses the human-machine interface of the control panel 11 to control the hanging mechanism 5 to lift it to the bottom elevation position required for the installation of the tunnel ventilation duct, and then the staff installs the tunnel ventilation duct.

[0049] Finally, after the ventilation pipes at the top of the tunnel are installed, the human-machine interface of the control panel 11 controls the placement frame 6 of the hanging mechanism 5 to reach the base 1. Then, the human-machine interface of the control panel 11 controls the four sets of hydraulic lifting columns 7 to descend to the initial position, and the staff come down from the protective ladder 8.
