Description

Technical Field

[0001] This invention belongs to the field of track construction equipment technology, specifically a track laying device for urban track shield tunneling and its usage method. Background Technology

[0002] Tunnels are engineering structures buried in the earth's strata and are a form of human utilization of underground space. Tunnels can be divided into traffic tunnels, hydraulic tunnels, municipal tunnels, mining tunnels, and military tunnels.

[0003] However, in the existing technology, due to the limited construction space, it is not convenient to use large machinery to move and lay the tracks during actual track use, which makes the actual track laying process more difficult. At the same time, when using different track equipment, it is necessary to lay many temporary tracks, which increases the actual construction workload and results in low overall efficiency. Furthermore, the laying of many temporary tracks affects the construction and use of other equipment, resulting in low overall construction efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a track laying device and its usage method for urban rail shield tunnel construction that can be easily modified according to actual usage needs, thereby meeting the needs of different track equipment, improving the versatility of actual equipment use, facilitating the laying of the track body, improving actual construction efficiency, effectively reducing the laying of the track body, thereby increasing the installation space for other construction equipment, and effectively improving actual usage efficiency.

[0005] The technical solution adopted in this invention is as follows: A track laying device for urban rail shield tunneling construction includes: a first adjustment mechanism, the first adjustment mechanism including a first bottom frame and limiting components, limiting grooves are opened on both ends of the bottom surface inside the first bottom frame, and a set of threaded holes are opened on both sides of the bottom surface inside the first bottom frame near the center, with a total of four threaded holes in each set, and two sets of limiting components are provided, both sets of limiting components being provided on the first bottom frame;

[0006] The second adjustment mechanism includes a second base frame and supporting components. The top of the second base frame has four placement slots and six sets of positioning holes, with four holes in each set. Four sets of supporting components are provided, all mounted on the second base frame.

[0007] A limiting mechanism, the limiting mechanism including a track body, the track body being disposed on a first bottom frame and a second bottom frame.

[0008] Among them, four L-shaped limiting blocks are fixedly connected at equal intervals on one side of the outer surface of the first bottom frame, and a stop piece is slidably inserted inside one of the L-shaped limiting blocks.

[0009] Each of the limiting components includes a gasket, which is slidably embedded in the corresponding limiting groove. The top of the gasket has two retaining holes, and a retaining bolt is slidably inserted into each retaining hole. A retaining groove is formed on one side of the outer surface of each retaining bolt. A connecting groove is formed near the four corners of the top of the gasket, and a connecting ring is slidably embedded in two of the connecting grooves.

[0010] Each of the limiting grooves has an installation groove on its inner bottom surface, and multiple support wheels are equidistantly connected to the inner surface wall on both sides of each installation groove.

[0011] Each of the L-shaped limiting blocks has an insertion port on both outer surfaces, and a retaining piece is slidably inserted into each of the two insertion ports, with one end of each retaining piece extending into the corresponding retaining groove.

[0012] Each set of support components includes a mounting frame, which is fixedly connected between the two inner walls of the second bottom frame. An adjusting shaft is rotatably connected to the top of the mounting frame, and a connecting bevel gear is sleeved on the outer surface of the adjusting shaft. A worm gear is rotatably connected to the top surface inside the mounting frame, and a connecting bevel gear is also sleeved on the outer surface of the worm gear near one end edge. The two connecting bevel gears mesh. A lifting threaded rod is rotatably connected between the top surface and the bottom surface inside the mounting frame. The bottom end of the lifting threaded rod extends to the bottom of the mounting frame, and a worm wheel is sleeved on the outer surface of the lifting threaded rod. The worm wheel meshes with the worm gear.

[0013] Each of the lifting threaded rods has a lifting frame threadedly connected to its outer surface. Each lifting frame is slidably embedded in the corresponding placement slot. Two support shafts are rotatably connected between the two sides of each lifting frame relative to the inner surface wall. Each support shaft has a movable wheel slidably sleeved on its outer surface.

[0014] The track body has a first connecting hole at each of the four corners on its inner bottom surface. Two of the first connecting holes are slidably inserted with a retaining bolt, and each retaining bolt is threadedly connected to a corresponding connecting ring.

[0015] The track body has multiple second connecting holes equidistantly spaced on the bottom surface near both sides. Four of the second connecting holes are connected to the corresponding positioning holes, and each second connecting hole and the corresponding positioning hole has a slidably inserted bolt.

[0016] A method for using a track laying device for urban rail shield tunneling includes the following steps:

[0017] S1. Installation and Laying: By rotating the adjusting shaft, the rotating adjusting shaft can drive the corresponding worm gear to rotate through the connecting bevel gear. The rotating worm gear, in turn, drives the corresponding lifting threaded rod to rotate. This allows the lifting threaded rod to adjust the height of the lifting frame within the placement slot, gradually raising the moving wheels above the inner bottom surfaces of the first and second bottom frames. The track body is then placed between the tops of the corresponding moving wheels, facilitating easy adjustment and movement of the track body for convenient transport until the track body is moved... The track body is delivered to the designated location, and then the adjusting shaft is rotated in the opposite direction to gradually retract the moving wheels into the corresponding placement slot. This allows the track body to be stably placed on the bottom surface of the corresponding first and second bottom frames. The two sets of threaded holes, in conjunction with the first connecting hole and the fixing bolt, can fix one end of the track body. This allows the two track bodies at this interval to meet the needs of existing track transport equipment. At the same time, the connecting ring inside the gasket connecting slot, in conjunction with the fixing bolt, can fix one end of the other two track bodies. This allows the two track bodies at this interval to meet the needs of existing tunnel boring machines.

[0018] S2. Structural Adjustment: After the existing shield tunneling equipment operation is completed, the shims can be removed, and the corresponding fixing plates can be easily pulled out from the corresponding insertion slots and fixing grooves. With the support of the support wheels, the shims can move and support the two ends of the corresponding track body, which facilitates the adjustment of the position of the corresponding track body. The adjusted track body, together with the track body in the fixed position that cannot be moved, forms multiple sets of track spacings that can be used by existing track transportation equipment, so that the equipment can meet the needs of more existing track transportation equipment.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0020] In this invention, during use, rotating the adjusting shaft, which in turn drives the corresponding worm gear to rotate via a bevel gear, allows the rotating worm gear to engage with a worm wheel to drive the corresponding lifting threaded rod to rotate. This allows the lifting threaded rod to effectively adjust the height of the lifting frame within the placement slot, gradually raising the moving wheels above the inner bottom surfaces of the first and second base frames. The track body is then placed between the tops of the corresponding moving wheels, facilitating easy adjustment and movement of the track body until it reaches the designated position. Reversing the rotation of the adjusting shaft retracts the moving wheels into the corresponding placement slot, allowing the track body to be stably placed on the inner bottom surfaces of the first and second base frames. Two sets of threaded holes, along with the first connecting hole and the retaining bolt, effectively secure one end of the track body, allowing the two track bodies spaced apart to... The system meets the needs of existing rail transport equipment. Simultaneously, through the connecting ring inside the shim connecting groove and the fixing bolt, two additional track bodies can be fixedly connected at one end. This allows the two track bodies with this spacing to meet the needs of existing tunnel boring machines (TBMs). Therefore, the equipment can satisfy both existing rail transport equipment and existing TBMs during actual use, improving the actual operational efficiency. After the existing TBM operation is completed, the shim can be removed, and the corresponding fixing plate can be easily pulled out from the corresponding insertion port and fixing groove. With the support of the support wheels, the shim can move and support both ends of the corresponding track body, facilitating the adjustment of the track body's position. This allows the adjusted track body, combined with the fixed track body that cannot be moved, to form multiple sets of track spacings usable by existing rail transport equipment. This enables the equipment to meet the needs of more existing rail transport equipment, effectively improving the overall construction process and allowing the equipment to efficiently perform its intended functions.

[0036] The following provides a detailed description of the method of using a track laying device for urban rail shield tunneling, as provided in an embodiment of the present invention. The method of use includes the following steps:

[0037] Step 1, Installation and Laying: By rotating the adjusting shaft 203, the rotating adjusting shaft 203 can effectively drive the corresponding worm 204 to rotate through the connecting bevel gear. The rotating worm 204, in turn, can drive the corresponding lifting threaded rod 205 to rotate through the worm wheel 206. This allows the rotating lifting threaded rod 205 to effectively adjust the height of the lifting frame 207 within the placement groove, gradually raising the moving wheels 209 above the inner bottom surfaces of the first and second base frames 101. The track body 301 is then placed between the tops of the corresponding moving wheels 209, facilitating easy movement and adjustment of the track body 301's position. This facilitates the movement and transport of the track body 301 until it reaches the designated usage position. Then, by reversing the rotation of the adjusting shaft 203... 03. Then, the moving wheel 209 is gradually retracted into the corresponding placement slot, so that the track body 301 can be stably placed on the bottom surface of the corresponding first bottom frame 101 and second bottom frame 201. Then, through the two sets of threaded holes, the first connecting hole and the fixing bolt 302 can effectively fix one end of the track body 301, so that the two track bodies 301 with this medium spacing can meet the use of existing track transportation equipment. At the same time, through the connection ring 106 inside the groove of the gasket 105 and the fixing bolt 302, the other two track bodies 301 can be fixedly connected at one end, so that the two track bodies 301 with this spacing can meet the use of existing shield tunneling equipment. Thus, in actual use, the equipment can meet the use of both existing track transportation equipment and existing shield tunneling equipment, improving the actual use effect of the equipment.

[0038] Step 2, Structural Adjustment: After the existing shield tunneling equipment operation is completed, the shim 105 can be removed, which facilitates the extraction of the corresponding fixing plate 107 from the corresponding insertion port and fixing groove. With the support of the support wheel 104, the shim 105 can move and support the two ends of the corresponding track body 301, thus facilitating the adjustment of the position of the corresponding track body 301. The adjusted track body 301, together with the fixed track body 301 that cannot be moved, forms multiple sets of track spacings that can be used by existing track transportation equipment. This allows the equipment to meet the needs of more existing track transportation equipment, effectively improving the overall construction process and enabling the equipment to efficiently perform its intended functions.
