Description

Technical Field

[0001] The present invention belongs to the technical field of tunnel construction equipment, and in particular relates to an assembled tunnel multi-directional linkage intelligent assembly trolley. Background Art

[0002] With the rapid development of the economy, the demand for traffic has also increased. As a convenient and efficient structural form, the development speed of tunnels is getting faster and faster, and the number of tunnels is increasing. In order to meet the current demand for increasing traffic volume, two-way tunnels with eight lanes or more with large cross-sections and many lanes are often used in municipal engineering. When the tunnel passes through a thin covering soil layer, the open-cut method is often used for construction. The open-cut method refers to the underground engineering construction method of first digging the ground, building the lining in the open air, and then covering and backfilling. It is mostly used for shallow buried tunnels. The open-cut method is the most basic and most commonly used method in urban underground engineering construction. The cast-in-place method is a relatively traditional and conservative construction method, but in the context of rapid urbanization, the cast-in-place method has attracted attention and discussion in the industry due to factors such as long construction period and greater impact on existing traffic. In comparison, the use of factory-prefabricated assembled tunnels can eliminate backward production capacity and solve the above problems; realize intensive and standardized production, generate industrial scale economic benefits; greatly improve the quality and durability of the project; shorten the construction period, and obtain social and environmental benefits. This is the development direction of national manufacturing and engineering. Moreover, prefabricated tunnels can save raw materials and reduce carbon emissions, which is a positive response to the country's "dual carbon" strategy and has good environmental and social benefits. At the same time, prefabricated tunnels are also in line with the country's policy orientation of building "quality projects", and an important measure to build "quality projects" is to "focus on overall design and promote the standardization of engineering construction."

[0003] At present, in the application of assembly trolleys, more are the bracket trolleys used in subway station projects. They are large in size and heavy in weight. The installation of the whole machine is complicated and requires professional technicians to complete the installation. The operation is complicated and the subsequent construction process requires professional assembly technicians. Once an error is made, it will take a lot of manpower and material resources to rework, which can easily affect the construction progress.

[0004] Therefore, some devices for assembling tunnel linings have also appeared in the prior art, such as a lining trolley with patent number CN2018114660645. Its working principle is to clamp and support the lining through the device, then move the lining to the invert, and then move the lining downward to achieve the assembly of the lining and the invert. However, the above-mentioned devices in the prior art all have a problem that affects the lining assembly rate. That is, when the device clamps the lining, it is necessary to place the lining accurately in the designated clamping position of the device through hoisting or other means. The clamping mechanism provided on the device can clamp the lining (fixed position can improve assembly accuracy), and the alignment of the lining and the clamping mechanism of the device (fitting positioning in the horizontal direction and sliding position positioning in the vertical direction) is a very time-consuming and relatively difficult problem, which will greatly affect the construction efficiency of the tunnel. Summary of the invention

[0005] In view of this, the purpose of the present invention is to provide an assembled tunnel multi-directional linkage intelligent assembly trolley to solve the problem in the prior art that when the lining device is clamping the lining, the alignment between the lining and the clamping device is difficult and takes a long time, which affects the lining assembly efficiency.

DETAILED DESCRIPTION

[0037] like Figures 1 to 10 As shown, the present invention is an assembled tunnel multi-directional linkage intelligent assembly trolley, including a frame 1, on which a component connection system 5 is provided. The function of the component connection system 5 is to clamp and position the lining component A and the lining component B on the assembly trolley, so as to facilitate subsequent precise movement and assembly operations. Specifically, the component connection system 5 includes a component reserved component 501 arranged on the lining component and a plurality of component connection components 502 symmetrically arranged on the frame 1. The component reserved component 501 refers to a component arranged on the lining when the lining is manufactured, and the component connection component 502 is a component arranged on the trolley for use in conjunction with the component reserved component 501 arranged on the lining to achieve rapid positioning and clamping.

[0038] In this specific embodiment, the component reserved component 501 includes an embedded block 5011 arranged on the inner side of the lining component, and the embedded block 5011 can be a steel component of a preset value. The component connecting component 502 includes a fixed seat 5027 slidably arranged on the frame 1, and an L-shaped supporting arc block 5021 is provided on the fixed seat 5027. Specifically, the curvature of the L-shaped supporting arc block 5021 is consistent with the bending amplitude of the lining component, and one side of the L-shaped supporting arc block 5021 is used to support the lining component and contact the inner side of the lining component. The L-shaped supporting arc block 5021 is provided with a through groove 5022 for limiting the sliding position of the embedded block 5011 on the L-shaped supporting arc block 5021. The position of the through groove 5022 is on the side of the L-shaped supporting arc block 5021 that contacts the lining component. A first fixed block is provided on the bottom surface of the block 5021, and a rotating motor 5029 is provided on the outer side of the first fixed block. A screw 5030 is provided on the output end of the rotating motor 5029, and a clamping assembly is provided on the screw 5030. The clamping assembly includes a clamping plate 5024, a sliding clamping channel 5025 and a second fixed block 5026 connected in sequence. The clamping plate 5024 is located above one side of the L-shaped supporting arc block 5021 and is arranged opposite to the other side of the L-shaped supporting arc block 5021. The through groove 5022 is slidably clamped on a side surface of the L-shaped supporting arc block 5021 in contact with the lining member. A nut 5028 is provided on the second fixed block 5026. The nut 5028 and the screw 5030 are threadedly connected. When the rotating motor 5029 is working, it drives the clamping assembly to slide on one side surface of the L-shaped supporting arc block 5021.

[0039] The working principle of the above-mentioned component connection system 5 is:

[0040] The construction workers lift the lining component by hoisting or other means, and then place the lining component on the L-shaped supporting arc block 5021. At this time, they only need to place the lining component downward by the hoisting setting. The lining component will slide on the L-shaped supporting arc block 5021 under the action of gravity, that is, the embedded block 5011 will slide in the through groove 5022. When the embedded block 5011 slides to the bottom end of the through groove 5022, it will contact the edge of the through groove 5022, that is, the movement of the lining component is limited. That is, at this time, the lining component moves to the specified position in the vertical direction, and then the rotating motor 5029 is started. The rotation of the rotating motor 5029 will drive the clamping assembly Movement, that is, at this time, the sliding clamping channel 5025 slides on one side surface of the L-shaped supporting arc block 5021, that is, when it slides to a certain position, the clamping plate 5024 will contact the lining component, thereby pushing the lining component to move laterally, and then the lining Houjian and the other side surface of the L-shaped supporting arc block 5021 are in contact and pressed tightly, that is, the lining component reaches the specified lateral position, that is, the lining component is quickly and accurately positioned, and at the same time, under the action of the clamping plate 5024, the lining component is clamped and limited between the clamping plate 5024 and one side surface of the L-shaped supporting arc block 5021, thereby realizing the fixation of the lining component and ensuring its stability and position retention during the movement.

[0041] It should be noted that the position of the embedded parts on the lining component is set according to the size of the lining component and the position of the L-shaped supporting arc block 5021 on the trolley. Therefore, when the lining component is clamped, the lining component is fixed and positioned at the specified assembly position. At the same time, the setting of the sliding clamping channel 5025 can enable the clamping plate 5024 to have a distance for moving back and forth, that is, it can achieve clamping and limiting of lining components of different widths, and at the same time, it can avoid space so that the lining component can be more easily placed on the L-shaped supporting arc block 5021, thereby improving the efficiency of clamping. Furthermore, after the assembly is completed, it is only necessary to reset the clamping plate 5024 to achieve rapid separation of the lining component and the trolley.

[0042] In one practicable manner, the embedded block 5011 is further provided with a slot 5012, the fixed seat 5027 is provided with a linear motor 5031, and a block 5032 is fixedly provided on the output end of the linear motor 5031, the height of the block 5032 is equal to the height of the slot 5012, and the width of the block 5032 is less than the width of the slot 5012. When the lining member is positioned, the linear motor 5031 works and extends the block 5032 provided thereon into the slot 5012 provided on the embedded block 5011, that is, the block 5032 will limit the vertical movement of the embedded block 5011. , which can improve the limiting effect on the lining component and avoid the problem of rotational separation during movement and force application; it should also be noted that the block 5032 only needs to limit the rotation of the lining component, so it can be achieved by matching only in the height direction, that is, the width of the block 5032 is always smaller than the width of the slot 5012. The advantage is that even if the width of the lining component is inconsistent, resulting in the position of the through slot 5022 on the embedded block 5011 changing, since the width of the block 5032 is smaller, the block 5032 can also enter the slot 5012 to achieve the limiting effect.

[0043] In one practicable manner, an abutment block 5033 is further provided on the end of the clamping block 5032, and the height of the abutment block 5033 is greater than the height of the clamping slot 5012. The setting of the abutment block 5033 can press the embedded block 5011 against the side wall of the through slot 5022, thereby further limiting the position of the lining component on the component connection system 5 to ensure its fixed stability, and at the same time provide a certain reaction force when the trolley drives the lining component to move downward and assemble with the invert arch, to avoid the lining component from moving and rotating when receiving the upward force.

[0044] In one practicable manner, light rods are symmetrically arranged on both sides of the screw rod 5030, one end of the light rod is fixed to the first fixing plate 5023, and the other end of the light rod is slidably connected to the second fixing block 5026. The setting of the light rod can improve the stability of the clamping assembly when it moves.

[0045] In one practicable manner, a component translation system 6 is further provided on the frame 1, and the component translation system 6 includes a plurality of hydraulic rods 601 fixed on the frame 1, and the output ends of the hydraulic rods 601 are fixed on the fixed seats 5027. The hydraulic rods 601 are used to drive the fixed seats 5027 to slide on the frame 1. The function of the component translation system 6 is to drive the fixed seats 5027 set on both sides to slide, that is, the lining component A and the lining component B can be brought closer together, that is, the upper ends of the two can be pre-spliced ​​into a ring shape.

[0046] In one practicable manner, the frame 1 is further provided with a component tensioning system 7, which includes an operating platform 701, on which a hydraulic lifting platform 702 is provided, and on which a tensioning device 703 for tensioning the upper end of the lining component is provided on the hydraulic lifting platform 702. It should be noted that the hydraulic lifting platform 702 and the tensioning device 703 are prior arts and will not be described in detail herein. The purpose of setting the component tensioning system 7 is to tension the annular seam and the longitudinal seam to the design value and complete the assembly.

[0047] In one feasible manner, a personnel passage system 11 is provided on the frame 1, and the personnel passage system includes a plurality of interconnected pedestrian passages, the pedestrian passages are composed of hollow steel plates and guardrails, and the personnel passage system is set up in multiple locations to ensure smooth passage of trolleys and convenient access to the construction site.

[0048] In an practicable manner, it also includes a main lifting system 201, an auxiliary lifting system 202, a translation system 3, a walking system 4, a hydraulic control system 8, a remote intelligent control system 9 and a signal transmission system 10 which are arranged on the frame 1.

[0049] In one practicable manner, the hydraulic control system 8 includes an operating console 801 and a hydraulic station 802 .

[0050] The trolley lifting system (main lifting system 201, auxiliary lifting system 202), translation system 3, and walking system 4 can respectively realize multi-directional linkage of the frame up and down, left and right, and front and back, and then combine together to form a movable trolley structure.

[0051] The component translation system 6 can realize independent or synchronous translation of components, the component tensioning system 7 can complete the tensioning work on the trolley, optimize the installation process of the tensioning equipment, save labor and improve efficiency, the hydraulic control system (8) can realize mechanical control, and the remote intelligent control system 9 can be connected to the hydraulic control system 8 through the signal transmission system 10 to realize remote intelligent control, facilitate the operation and observation of the operators, and improve safety. It should be noted that most of the mobile systems or walking systems in this technical solution are existing technologies, and can refer to the mobile trolleys used in tunnels in the existing technology.

[0052] Specifically, in this embodiment, the assembly trolley is first moved to a predetermined position by controlling the main lifting system 201, the auxiliary lifting system 202, and the trolley travel system 4, and then the prefabricated components A and B are respectively fixed on the assembly trolley through the component connection system 5, and the prefabricated components A and B are circumferentially closed through the component translation system 6; secondly, the prefabricated lining and the cast-in-place invert C are aligned through the main lifting system 201, the auxiliary lifting system 202, and the trolley translation system 3, the control trolley lifting system is controlled to lower the prefabricated lining onto the invert, and the control trolley travel system 4 makes the ring-shaped prefabricated lining close to the previous ring prefabricated lining; thirdly, the ring seam and the longitudinal seam are tensioned to the design value through the component tensioning system 7 to complete the assembly; finally, the prefabricated lining is separated from the component connection system 5, and the trolley independently moves to the next ring assembly position.

[0053] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it.
