Description

Technical Field

[0001] The utility model belongs to the technical field of shield machines, and particularly relates to a segment transportation device for a shield machine. Background Technique

[0002] The shield method is an important underground tunnel construction technology, especially suitable for tunnel excavation in soft soil strata. With the acceleration of the urbanization process, the development and utilization of underground space have become increasingly important. Due to its high construction efficiency and little impact on the surrounding environment, the shield method has been widely used in the construction of urban subways, highway tunnels, drainage pipes and other projects.

[0003] During the shield construction process, the transportation and installation of segment components are important but complex tasks. The traditional methods for transporting and installing segment components have the following problems and disadvantages: In the traditional methods, due to the lack of a hoisting and dropping guiding structure for segment components on the transport vehicle, the hoisting and positioning of segment components onto the transport vehicle often rely on manual operation, which is prone to safety accidents. Workers need to hold the segment components by hand during the hoisting process to hoist them onto the transport vehicle, increasing the risk of injury.

[0004] After retrieval, for example, in the existing Chinese patent publication number: CN217976252U, a segment transportation device for a shield machine includes a transport trolley. A support block is installed on the top of the transport trolley, and a support column is installed on the top of the support block. A side plate is installed on the top of the support block, and a top plate is connected to the top of the side plate. A first threaded hole is opened on the top of the top plate, and a fixing bolt is installed inside the first threaded hole. A hydraulic cylinder is installed at the bottom of the top plate.

[0005] The cited patent literature also has the same problem. Due to the lack of a hoisting and dropping guiding structure for segment components on the transport vehicle, the hoisting and positioning of segment components onto the transport vehicle often rely on manual operation, which is prone to safety accidents. Workers need to hold the segment components by hand during the hoisting process to hoist them onto the transport vehicle, increasing the risk of injury. Content of the Utility Model

[0006] The purpose of the utility model is to provide a segment transportation device for a shield machine to solve the problems raised in the background technique.

[0007] To achieve the above purpose, the utility model provides the following technical solution: A segment transportation device for a shield machine, including:

[0008] A segment transportation assembly, including a transport vehicle and a segment bearing box arranged on the top surface of the transport vehicle for bearing segment components. A plurality of segment clamping templates that fit together with the segment components are symmetrically arranged in the inner cavity of the segment bearing box. The plurality of segment clamping templates equally divide the inner cavity of the segment bearing box into a plurality of transport unit bins for bearing hoisted and dropped segment components;

[0009] The guiding and moving mechanism is installed on the top surface of the transport vehicle, and its upper end spans above the segment bearing box;

[0010] The segment feeding-in silo guiding assembly includes a hoisting guiding and feeding silo installed at the upper end of the guiding and moving mechanism. The hoisting guiding and feeding silo has a funnel-shaped structure with both upper and lower ends communicating. When the segment is hoisted vertically, the segment falls from the hoisting guiding and feeding silo into the corresponding transport unit silo. By driving the hoisting guiding and feeding silo to move above the segment bearing box through the guiding and moving mechanism, the segments falling into the silo in sequence enter the corresponding transport unit silos. Thus, a series of guiding and falling through the hoisting guiding and feeding silo can replace the operation of manually holding the segment during hoisting and falling, improving safety. In the inner cavity of each transport unit silo, there is a segment clamping plate for clamping the segment.

[0011] Preferably in this solution, the arc-shaped outer wall of each segment clamping template is in fitting contact with the arc-shaped inner wall of the adjacent segment. The segment clamping plate is located on the back of the segment and moves towards the segment for clamping.

[0012] Preferably in this solution, on the back of each segment clamping plate, hydraulic push-pull clamping rods are symmetrically installed, and the tail ends of the hydraulic push-pull clamping rods are installed on the back of the adjacent segment clamping template.

[0013] Preferably in this solution, a rubber protection pad is bonded to the inner wall of the segment clamping plate, and the rubber protection pad elastically abuts against the arc-shaped outer wall of the segment.

[0014] Preferably in this solution, the guiding and moving mechanism includes two linear guide rails symmetrically installed on both sides of the segment bearing box and on the top surface of the transport vehicle, slider supports slidably installed on the top surface of each linear guide rail, and an inverted U-shaped fixed bracket symmetrically welded on the top surfaces of the two slider supports.

[0015] Preferably in this solution, the hoisting guiding and feeding silo is installed at the middle position on the top surfaces of the two U-shaped fixed brackets, and the inner walls on both sides of the hoisting guiding and feeding silo are both set as guiding inclined slopes.

[0016] Preferably in this solution, clamping outer plates are welded on the outer walls at both ends of the bottom of the hoisting guiding and feeding silo. Each clamping outer plate is connected to the U-shaped fixed bracket through a detachable bolt. Thus, the hoisting guiding and feeding silo can be installed, disassembled, or replaced with different specifications and dimensions to conform to the hoisting guiding and feeding silo of the segment.

[0017] Preferably, a positioning disc is welded between the outer walls of the two U-shaped fixing brackets through a connecting rod. On the outer wall of the segment bearing box and on the side facing the positioning disc, a plurality of positioning grooves are equidistantly arranged. Each positioning groove is aligned with the center of the adjacent transportation unit bin. When the positioning disc moves to align with one of the positioning grooves, it indicates that the bottom end of the hoisting and guiding blanking bin is located at the middle position of the transportation unit bin corresponding to the positioning groove, which is convenient for blanking the segment parts and prevents the segment parts from falling and shifting.

[0018] Preferably, a shock-absorbing and buffering groove is opened on the top surface of the transport vehicle below the segment bearing box. A plurality of buffer air springs are symmetrically installed on the inner bottom wall of the shock-absorbing and buffering groove. A buffer support plate is installed on the top surface of the buffer air spring, and the buffer support plate abuts upward against the bottom surface of the segment bearing box that sinks into the shock-absorbing and buffering groove. A hoisting screw hole is opened on the top surface of each segment part, and a hoisting ring is installed in cooperation with the hoisting screw hole for hoisting operations in the workshop. A trolley armrest is installed on one side edge of the top surface of the transport vehicle, and walking wheels are installed at the four corners of the bottom surface of the transport vehicle.

[0019] The beneficial effects of the present utility model are:

[0020] 1) For this segment transport device of the shield machine, a series of guiding and falling of the hoisting and guiding blanking bin replaces manual intervention, reduces the risk of manual operation, and reduces the accident rate. By using the hoisting and guiding blanking bin to replace the operation of manually holding the segment parts and hoisting them down, the safety of the hoisting process is significantly improved. Workers no longer need to directly participate in the hoisting and positioning process of the segment parts, thus reducing their labor intensity. The degree of manual participation is reduced, and the physical burden on the staff is reduced.

[0021] 2) Through the design of the segment clamping plate and the rubber protection pad, the risk of damage to the segment parts during transportation is reduced. The segment clamping plate ensures the stability of the segment parts in the transportation unit bin, and the rubber protection pad protects the surface of the segment parts from damage. Through the buffer air springs and the buffer support plate in the shock-absorbing and buffering groove, the vibration during transportation is effectively absorbed.

Specific embodiments

[0029] Next, embodiments will be combined to clearly and completely describe the technical solutions of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present utility model.

[0030] This embodiment provides a segment transportation device for a shield machine as shown in Figures 1 - 5 Figure, including: segment transportation assembly 1, guiding and moving mechanism 2, segment feeding-in guiding assembly 3.

[0031] In this embodiment, the segment transportation assembly 1 includes a transport vehicle 4 and a segment bearing box 5 arranged on the top surface of the transport vehicle 4 for bearing segment parts 7. A plurality of segment clamping templates 20 that fit with the segment parts 7 are symmetrically arranged in the inner cavity of the segment bearing box 5. The plurality of segment clamping templates 20 equally divide the inner cavity of the segment bearing box 5 into a plurality of transport unit bins 8 for bearing the hoisted and dropped segment parts 7; each segment part 7 is stored separately in the transport unit bin 8 to separate the segment parts 7, avoid mutual interference, and ensure the stability of the segment parts 7 during transportation.

[0032] In this embodiment, the guiding and moving mechanism 2 is installed on the top surface of the transport vehicle 4 and its upper end spans above the segment bearing box 5; the guiding and moving mechanism 2 controls the horizontal movement of the hoisting guiding and discharging bin 9 to ensure that the segment parts 7 can accurately fall into the designated transport unit bin 8, improving the accuracy and efficiency of the loading of the segment parts 7 and reducing the risk of manual operation. The segment bearing box 5 is used to bear the segment parts 7 and separate the transport unit bins 8 to ensure the stability of the segment parts 7 during transportation, reduce the collision between the segment parts 7, and lower the risk of damage.

[0033] In this embodiment, the segment feeding guide assembly 3 includes a hoisting guide feeding bin 9 installed at the upper end of the guiding and moving mechanism 2. The hoisting guide feeding bin 9 has a funnel-shaped structure with both upper and lower ends being through. The segment feeding guide assembly 3 guides the segment member 7 into the transportation unit bin 8, ensuring that the segment member 7 can smoothly fall from the hoisting guide feeding bin 9 into the transportation unit bin 8, realizing the automatic guiding and loading of the segment member 7, and improving the loading speed and safety. The hoisting guide feeding bin 9 is used for the vertical guiding and feeding of the segment member 7, enabling the segment member 7 to smoothly fall into the transportation unit bin 8, and improving the safety and efficiency of the loading process.

[0034] In this embodiment, when the segment member 7 is hoisted vertically, the segment member 7 falls from the hoisting guide feeding bin 9 into the corresponding transportation unit bin 8. The guiding and moving mechanism 2 drives the hoisting guide feeding bin 9 to move above the segment bearing box 5, and the segment member 7 falling in sequence enters the corresponding transportation unit bin 8. Thus, through a series of guiding and falling of the hoisting guide feeding bin 9, the operation of manually holding the segment member 7 during hoisting and falling can be replaced, improving safety. A segment clamping plate 21 for clamping the segment member 7 is provided in the inner cavity of each transportation unit bin 8.

[0035] In this embodiment, the arc-shaped outer wall of each segment clamping template 20 is in conformal contact with the arc-shaped inner wall of the adjacent segment member 7. The segment clamping plate 21 is located on the back of the segment member 7 and moves towards the segment member 7 for clamping. The segment clamping template 20 is used to separate the transportation unit bin 8, ensuring that the segment members 7 will not collide with each other during transportation and reducing the risk of damage to the segment members 7. The segment clamping plate 21 holds the segment member 7, moves through the hydraulic push-pull clamping rod 23, and fixes the segment member 7 to ensure the stability of the segment member 7 during transportation.

[0036] In this embodiment, a hydraulic push-pull clamping rod 23 is symmetrically installed on the back of each segment clamping plate 21. The tail end of the hydraulic push-pull clamping rod 23 is installed on the back of the adjacent segment clamping template 20. A rubber protection pad 22 is bonded to the inner wall of the segment clamping plate 21, and the rubber protection pad 22 elastically abuts against the arc-shaped outer wall of the segment member 7. The rubber protection pad 22 protects the segment member 7, reduces the friction between the segment member 7 and the segment clamping plate 21, and prevents damage to the surface of the segment member 7.

[0037] In this embodiment, the guiding and moving mechanism 2 includes two linear guide rails 10 symmetrically installed on both sides of the segment bearing box 5 and located on the top surface of the transport vehicle 4, a slider support 13 slidably installed on the top surface of each linear guide rail 10, and an inverted U-shaped fixing bracket 14 symmetrically welded on the top surfaces of the two slider supports 13. The linear guide rails 10 provide a guiding path for the slider support 13 to ensure the linear movement of the guiding and moving mechanism 2, achieving the precise positioning of the hoisting guiding blanking bin 9. The U-shaped fixing bracket 14 fixes the hoisting guiding blanking bin 9 and provides support for the hoisting guiding blanking bin 9 to ensure the stability of the hoisting guiding blanking bin 9.

[0038] In this embodiment, the hoisting guiding blanking bin 9 is installed at the middle position on the top surfaces of the two U-shaped fixing brackets 14, and the inner walls on both sides of the hoisting guiding blanking bin 9 are both provided with guiding inclined slopes 12. The guiding inclined slopes 12 provide a guiding inclined surface for the segment member 7 to ensure that the segment member 7 can slide smoothly, reduce the resistance when the segment member 7 falls, and improve the loading efficiency.

[0039] In this embodiment, clamping outer plates 15 are welded on the outer walls on both sides of the bottom end of the hoisting guiding blanking bin 9, and each clamping outer plate 15 is connected to the U-shaped fixing bracket 14 through a detachable bolt. Thus, the hoisting guiding blanking bin 9 can be installed, disassembled or replaced with different specifications and sizes to conform to the hoisting guiding blanking bin 9 of the segment member 7.

[0040] In this embodiment, a positioning disk 17 is welded between the outer walls of the two U-shaped fixing brackets 14 through a connecting rod 16, and a plurality of positioning grooves 18 are equidistantly opened on the outer wall of the segment bearing box 5 and on the side facing the positioning disk 17, and the center of each positioning groove 18 is aligned with the adjacent transport unit bin 8. When the positioning disk 17 moves to align with one of the positioning grooves 18, it indicates that the bottom end of the hoisting guiding blanking bin 9 is located at the middle position of the transport unit bin 8 corresponding to the positioning groove 18, which is convenient for blanking the segment member 7 and prevents the segment member 7 from falling and deviating. The positioning disk 17 is used to position the hoisting guiding blanking bin 9, and aligning the positioning grooves 18 determines the correct position of the hoisting guiding blanking bin 9 to ensure that the segment member 7 accurately falls into the transport unit bin 8.

[0041] In this embodiment, a shock-absorbing buffer groove 24 is formed below the segment bearing box 5 and on the top surface of the transport vehicle 4. A plurality of buffer air springs 26 are symmetrically installed on the inner bottom wall of the shock-absorbing buffer groove 24. A buffer support plate 25 is installed on the top surface of the buffer air spring 26, and the buffer support plate 25 abuts upward against the bottom surface of the segment bearing box 5 that sinks into the shock-absorbing buffer groove 24. A hoisting screw hole 19 is formed on the top surface of each segment 7. The hoisting screw hole 19 is fitted with a hoisting ring for hoisting operations in the workshop. A trolley handrail 6 is installed on one side edge of the top surface of the transport vehicle 4, and traveling wheels 11 are installed at the four corners of the bottom surface of the transport vehicle 4. The buffer air springs 26 provide elastic support, absorb and relieve vibrations during transportation, protect the segments 7 from impacts, and extend the service life. The buffer support plate 25 supports and buffers the segment bearing box 5, and cooperates with the buffer air springs 26 to reduce vibrations and improve the stability of the segments 7 during transportation.

[0042] Working principle: For this segment transport device of the shield machine, after the segments 7 are produced, they are lifted to an appropriate height by a hoisting device such as a crane, using the hoisting screw holes 19 on the segments 7 to cooperate with the installation of hoisting rings. At this time, the segments 7 are in a vertical state and are ready to be hoisted into the hoisting guiding and blanking bin 9.

[0043] The hoisting guiding and blanking bin 9 is moved to a suitable position to ensure that the segments 7 can smoothly pass through the guiding inclined slope 12 and enter the transport unit bin 8. The position of the hoisting guiding and blanking bin 9 is adjusted using the linear guide rail 10 and the slider support 13 on the guiding moving mechanism 2. When the positioning disk 17 is aligned with the positioning groove 18, it is confirmed that the hoisting guiding and blanking bin 9 is accurately aligned with the transport unit bin 8. The vertically hoisted segments 7 are placed at the top entrance of the hoisting guiding and blanking bin 9, and the segments 7 slide into the transport unit bin 8 through the guiding inclined slope 12. When the segments 7 fall into the transport unit bin 8, the hydraulic push-pull clamping rod 23 is used to drive the segment clamping plate 21 to move inward to fix the segments 7. A rubber protection pad 22 is attached to the inner wall of the segment clamping plate 21 to protect the surface of the segments 7 from damage.

[0044] The transport vehicle 4 is used to move the segment bearing box 5 containing the segments 7 to the required position. The transport vehicle 4 can be driven by manually pushing the trolley handrail 6, and the traveling wheels 11 ensure the smooth movement of the transport vehicle 4 on the ground.

[0045] When the segment bearing box 5 is subjected to impacts or vibrations, the vibrations are absorbed and relieved by the buffer air springs 26 and the buffer support plate 25 in the shock-absorbing buffer groove 24. The buffer air springs 26 are located in the shock-absorbing buffer groove 24, and the buffer support plate 25 abuts upward against the bottom of the segment bearing box 5 to reduce the vibrations of the segments 7 during transportation.

[0046] Use the guiding movement mechanism 2 to adjust the position of the hoisting guiding blanking bin 9 to load the next segment 7. Repeat the above steps until all the transportation unit bins 8 are filled. When the transport vehicle 4 reaches the destination, release the clamping state of the segment clamping plate 21 on the segment 7, and use the hoisting equipment to lift the segment 7 from the transportation unit bin 8 and install it at the predetermined position.

[0047] The above are only the preferred embodiments of the present invention. It should be understood that the present invention is not limited to the form disclosed herein, should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be changed within the scope of the concept described herein through the above teachings or the technology or knowledge in the relevant field. And the changes and modifications made by those skilled in the art do not depart from the spirit and scope of the present invention, then they should all be within the protection scope of the appended claims of the present invention.
