[0002] Currently, the railway tunnels constructed using precast inverted arch blocks in China mainly include the Xinjiang Tuku Second Line Railway, the Lanzhou-Chongqing Railway, and the Dali-Ruili Railway. These projects all use open-type, full-face tunnel boring machines (TBMs) for construction, requiring temporary fixing of rails on the precast inverted arch blocks for diesel locomotives to transport construction materials.

[0003] The traditional construction method for precast inverted arch blocks involves inserting double-headed threaded spikes with anchoring agents after demoulding to secure the temporary transport track.

[0035] A method for manufacturing and using a track structure with prefabricated sleeve inverted arch blocks comprises the following steps:

[0036] S1. Place the HDPE sleeve into the upper mold and connect it to the threaded part. After the blocking ring fits the top of the upper mold, fix the upper mold and the lower mold with bolts.

[0037] S2. Add concrete raw materials into the casting hole and wait for 24 hours to 48 hours;

[0038] S3. After the concrete solidifies, the mold body and the prefabricated block body are disassembled, and then the handle is turned to drive the positioning rod to rotate, so that the threaded portion is separated from the HDPE sleeve, and the HDPE sleeve remains in the prefabricated block body, thereby obtaining the prefabricated block body with the embedded HDPE sleeve;

[0039] S4, loop S1-S3 to obtain multiple prefabricated block bodies;

[0040] S5. Install a pad at each groove, arrange multiple prefabricated block bodies linearly, and then install the track body at the center of the multiple pads;

[0041] S6. Install a gauge plate at each prefabricated hole, with the side of the gauge plate close to the track body in contact with the rail bottom arc surface. Then, insert the double-headed threaded spike through the gusset plate, gauge plate, and prefabricated hole, and finally insert it into the HDPE sleeve.

[0042] S7. Place an assembly mechanism on the track body so that the track wheel can roll on the track body, then control the output end of the servo motor to drive the large sprocket to rotate, which in turn drives the small sprocket to rotate synchronously under the transmission action of the chain, and then drives the corresponding long shaft to rotate, and finally drives the two nut sleeves fixed to it to rotate synchronously;

[0043] S8. Shake the handle to rotate the extension rod, which in turn rotates the spur gear. The meshing action drives the rack downward, which in turn drives the protective shell and nut sleeve to move downward synchronously. The two nut sleeves are respectively placed on the upper side of the corresponding double-threaded spike. The double-threaded spike is rotated by the nut sleeve, and is threadedly connected to the HDPE sleeve. This simultaneously secures the pad, gauge plate, and track body, improving installation efficiency.

[0044] S9. When the track body needs to be disassembled, according to steps S7-S8, control the output end of the servo motor to drive the large sprocket to rotate in the opposite direction, thereby driving the two nut sleeves to rotate in the opposite direction. Then, the two nut sleeves are respectively sleeved on the upper side of the corresponding double-headed threaded spikes. The double-headed threaded spikes are driven by the nut sleeves to rotate in the opposite direction, so that the double-headed threaded spikes are gradually separated from the HDPE sleeves, thereby realizing rapid disassembly of the double-headed threaded spikes.

[0045] Compared with the prior art, the present invention has the following beneficial effects:

[0046] 1. This solution embeds an HDPE sleeve within the prefabricated block body, and then uses detachable double-threaded spikes to fix the track body. Compared with the traditional method of violently dismantling the double-threaded spikes after injecting anchor glue and then removing them, the double-threaded spikes can be reused after removal. The HDPE sleeve adopts a resin plastic structure with a low cost, which greatly reduces material costs. In addition, this solution adopts an assembly mechanism that can be used with double-threaded spikes for multiple functions. The double-threaded spikes can be quickly installed and removed and can be used during the movement of the track body, which greatly shortens the later disassembly period and effectively reduces labor costs.

[0047] 2. In this solution, the blocking ring fits the top of the upper mold to prevent liquid concrete from overflowing. Under the restriction of the blocking ring, the position of the threaded part entering the upper mold is fixed, and the position of the HDPE sleeve can be accurately embedded to ensure the accurate position of the HDPE sleeve.

[0048] 3. In this solution, the track body is located between the two gauge baffles during installation. One side of the two gauge baffles fits against the upper side of the rail bottom arc surface. The pad, gauge baffle and gusset plate are all provided with round holes for inserting double-headed threaded spikes. The double-headed threaded spikes are passed through the gusset plate, gauge baffle, pad and prefabricated holes from top to bottom, and finally inserted into the HDPE sleeve. When the double-headed threaded spikes are tightened, the pad, gauge baffle, gusset plate and track body can be fixed at the same time. The installation structure is simple and easy to assemble.

[0079] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0080] Example

[0081] See also Figures 1-12 , the technical solutions provided in this embodiment are as follows:

[0082] A track structure for a prefabricated block with an embedded sleeve inverted arch comprises a mold body 1, a prefabricated block body 2, a pad 6, a fixing mechanism, a positioning mechanism and an assembly mechanism 10, wherein: the mold body 1 comprises an upper mold 101, a lower mold 102 and a casting hole 103; the prefabricated block body 2 is cast and formed in the mold body 1, and two prefabricated block bodies 2 are pre-embedded therein; the pad 6 is embedded in the upper side of the prefabricated block body 2, and two gauge baffles 7 are detachably provided on its upper side; the fixing mechanism is arranged on the upper side of the pad 6, and sets up the track body 9 by linearly arranging the prefabricated block body 2 and the pad 6; the positioning mechanism is provided with multiple groups and is respectively located on the upper side of the corresponding upper mold 101, and is used to fix the pre-embedded position of the HDPE sleeve 3; the assembly mechanism 10 is movably arranged on the upper side of the track body 9, and two nut sleeves 11 are provided on the lower side of the assembly mechanism, which are used to drive the nut sleeves 11 to screw the double-headed threaded spikes 8 to achieve the purpose of assembling the track body 9.

[0083] In a specific embodiment of the present invention, there are two casting holes 103, both of which are set at the top convex part of the upper mold 101. When the block body 2 is prefabricated, the threaded portion 501 is threadedly connected to the HDPE sleeve 3. The HDPE sleeve 3 is located in the upper mold 101, and the blocking ring 502 is attached to the top of the upper mold 101. The upper mold 101 and the lower mold 102 are fixed with bolts and then liquid concrete is added to the casting hole 103. After the liquid concrete in the mold body 1 solidifies, the upper mold 101 and the lower mold 102 are disassembled to obtain the prefabricated block body 2 with the HDPE sleeve 3 embedded. According to the above steps, a large number of prefabricated block bodies 2 can be obtained, and the top of each prefabricated block body 2 is prefabricated with a groove 20 1 and prefabricated holes 202, a pad 6 is fitted in each groove 201, and then multiple prefabricated block bodies 2 are neatly arranged linearly, and the track body 9 can be installed on the pad 6. Two gauge baffles 7 are provided on the upper side of each pad 6. The two gauge baffles 7 are located on both sides of the track body 9. The side of the gauge baffle 7 close to the track body 9 is fitted on the rail bottom arc surface 901. The pad 6, the gauge baffle 7 and the gusset plate 701 are all provided with round holes for fitting the double-headed threaded spikes 8. The double-headed threaded spikes 8 are sequentially passed through the gusset plate 701, the gauge baffle 7, the pad 6 and the prefabricated holes 202 from top to bottom, and finally inserted into the HDPE sleeve 3 to correct the position of the preset double-headed threaded spikes 8. At this time, the track body 9 The assembly mechanism 10 is placed on the track so that the track wheel 1003 can roll on the track body 9, and then the output end of the servo motor 1304 is controlled to drive the large sprocket 1303 to rotate, and finally drive the two nut sleeves 11 fixed thereto to rotate synchronously. The height of the nut sleeve 11 can be controlled by the lifting mechanism 15 so that the nut sleeve 11 is respectively sleeved on the upper side of the corresponding double-headed threaded spike 8. When the nut sleeve 11 rotates, the double-headed threaded spike 8 can be tightened, so that the double-headed threaded spike 8 fixes the buckle plate 701, the gauge baffle 7, and the pad 6. Similarly, when the nut sleeve 11 rotates in the opposite direction, the double-headed threaded spike 8 can be loosened, so that the double-headed threaded spike 8 and the HDPE sleeve 3 can be quickly separated. This solution fixes the HDPE sleeve on the upper side of the mold body 1 3. The position positioning mechanism can accurately position the HDPE sleeve 3 in the mold body 1, and effectively limit the purpose of pre-embedded HDPE sleeve 3 in the prefabricated block body 2. Then, the track body 9 is fixed with the detachable double-headed threaded spikes 8. Compared with the traditional violent removal method after adding rebar glue and double-headed threaded spikes, the double-headed threaded spikes 8 can be reused after removal. The HDPE sleeve 3 adopts a resin plastic structure with a low cost, which greatly reduces the material cost. In addition, this solution adopts an assembly mechanism 10 that can be used in conjunction with the double-headed threaded spikes 8 for multi-functions. The double-headed threaded spikes 8 can be quickly installed and removed and can be used during the movement of the track body 9, which greatly shortens the later disassembly period and effectively reduces labor costs.

[0084] Preferably, the circumferential surface of the HDPE sleeve 3 is provided with an external thread groove. After the HDPE sleeve 3 is embedded in the prefabricated block body 2, it will not rotate with the double-headed threaded spike 8, thereby enhancing the fixing effect.

[0085] Specifically, each group of positioning mechanisms includes:

[0086] A U-shaped frame 4, which is fixedly connected to the top of the upper mold 101 and has a positioning groove 401 at its upper end; and

[0087] The positioning rod 5 is rotatable and can be raised and lowered in the positioning groove 401. The lower end of the positioning rod 5 is fixedly connected to a threaded portion 501, which is threadedly connected to the HDPE sleeve 3. The upper end of the positioning rod 5 is fixedly connected to a rotary handle 503.

[0088] A groove 201 is provided on the top of the prefabricated block body 2, and a prefabricated hole 202 is provided at the groove 201 corresponding to the positioning rod 5. The circumference of each positioning rod 5 is fixedly connected with a blocking ring 502, and the blocking ring 502 is attached to the top of the upper mold 101.

[0089] In a specific embodiment of the present invention, see Figure 1 and Figure 2 The position of the positioning groove 401 corresponds to the HDPE sleeve 3. The positioning rod 5 rotates and moves linearly up and down under the limit of the positioning groove 401. The threaded portion 501 is used to fix the position of the HDPE sleeve 3. The rod body of the positioning rod 5 enters the upper mold 101, thereby forming a prefabricated hole 202. The blocking ring 502 fits the top of the upper mold 101 to prevent liquid concrete from overflowing. Under the restriction of the blocking ring 502, the position of the threaded portion 501 entering the upper mold 101 is fixed, and the position of the HDPE sleeve 3 can be accurately embedded. The setting of the handle 503 makes it easier to rotate the positioning rod 5. After the prefabricated block body 2 solidifies, rotating the handle 503 drives the threaded portion 501 to rotate, so that the threaded portion 501 can be separated from the HDPE sleeve 3.

[0090] Specifically, each set of fixing mechanisms includes two sets of fixing components, the track body 9 is located between the two sets of fixing components, and rail bottom arc surfaces 901 are provided on both sides of the track body 9. Each set of fixing components includes a gauge baffle 7 and a double-headed threaded spike 8. The gauge baffle 7 is embedded in the top of the pad 6, one end of the gauge baffle 7 is embedded in the upper side of the pad 6, and the other end of the gauge baffle 7 is attached to the upper side of the rail bottom arc surface 901. The upper side of the gauge baffle 7 is connected to the buckle plate 701 through a hinge shaft, and the double-headed threaded spike 8 passes through the buckle plate 701, the gauge baffle 7, and the prefabricated hole 202 and is threadedly connected to the HDPE sleeve 3.

[0091] In a specific embodiment of the present invention, see Figure 5-Figure 7The pad 6 is fitted into the groove 201, and two gauge baffles 7 are provided on the pad 6. The buckle plate 701 is connected to the upper side of the gauge baffle 7 through a hinge shaft. The track body 9 is located between the two gauge baffles 7 when installed, and one side of the two gauge baffles 7 is in contact with the upper side of the rail bottom arc surface 901. The pad 6, the gauge baffle 7 and the buckle plate 701 are all provided with round holes for inserting the double-headed threaded spikes 8. The double-headed threaded spikes 8 are passed through the buckle plate 701, the gauge baffle 7, the pad 6 and the prefabricated hole 202 from top to bottom, and finally inserted into the HDPE sleeve 3. When the double-headed threaded spike 8 is tightened, the pad 6, the gauge baffle 7, the buckle plate 701 and the track body 9 can be fixed at the same time. The installation structure is simple and easy to assemble.

[0092] Specifically, the assembly mechanism 10 includes:

[0093] The assembly mechanism 10 includes a base 1001, a housing 1002, track wheels 1003, an extension frame 1004, and an armrest 1005. The base 1001 is located on the upper side of the track body 9, the housing 1002 is fixedly connected to the top of the base 1001, the track wheels 1003 are fixedly connected to the bottom of the base 1001, and the track wheels 1003 are rollingly connected to the upper side of the track body 9. The extension frame 1004 and the armrest 1005 are both fixedly connected to the side of the housing 1002.

[0094] The protective shell 12 is liftably mounted within the assembly mechanism 10. Two limiting cylinders 1201 are fixedly connected to its bottom. A limiting assembly is provided within the assembly mechanism 10 to limit the linear movement of the protective shell 12. The limiting assembly includes a limiting rod 14 and a sliding sleeve 1401. The limiting rod 14 is fixedly connected to the top of the base 1001. The sliding sleeve 1401 is slidably connected to the surface of the limiting rod 14. The sliding sleeve 1401 is fixedly connected to the side of the protective shell 12.

[0095] A rotating mechanism 13 is provided on the protective shell 12 and is used to drive the two nut sleeves 11 to rotate synchronously;

[0096] The lifting mechanism 15 is provided in the assembly mechanism 10 and is used to drive the nut sleeve 11, the protective shell 12 and the rotating mechanism 13 to rise and fall synchronously, so that the nut sleeve 11 screws the double-headed threaded spike 8 to achieve the purpose of installation and disassembly.

[0097] In a specific embodiment of the present invention, the track wheel 1003 is a metal wheel specifically used to move on the track body 9. The assembly mechanism 10 can be controlled to move back and forth on the track body 9 by pushing the handrail 1005. The shell 1002 is used to prevent dust and water, and moves linearly on the limiting straight rod 14 through the sliding sleeve 1401. The sliding sleeve 1401 is fixed to the protective shell 12, thereby limiting the up and down linear movement of the protective shell 12. The nut sleeve 11 follows the movement of the assembly mechanism 10. The nut sleeve 11 is provided with two double-headed threaded spikes 8 on both sides of the assembly mechanism 10. The double-headed threaded spikes 8 on each pad 6 are symmetrically arranged on the upper side of the track body 9. When one of the nut sleeves 11 is located on the upper side of the double-headed threaded spike 8, the other nut sleeve 11 is also located on the upper side of the other double-headed threaded spike 8.

[0098] Specifically, the rotating mechanism 13 includes:

[0099] There are two long shafts 1301, which are rotatably connected to the limiting cylinder 1201 respectively, and their lower ends are fixedly connected to the nut sleeve 11 respectively, and their upper ends are fixedly connected to the small sprocket 1302;

[0100] The large sprocket 1303 is rotatably connected to the protective shell 12;

[0101] A servo motor 1304 is fixedly connected to the bottom of the protective shell 12, and an output end thereof is fixedly connected to the large sprocket 1303; and

[0102] The chain 1305 is connected between the large sprocket 1303 and the two small sprockets 1302 .

[0103] In a specific embodiment of the present invention, the limiting cylinder 1201 is used to limit the rotation of the long shaft 1301. The lower end of the long shaft 1301 is fixed to the nut sleeve 11, and the upper end is fixed to the small sprocket 1302. The output end of the servo motor 1304 can rotate forward and reverse to drive the large sprocket 1303 to rotate. The chain 1305 is used to synchronize the large sprocket 1303 and the small sprocket 1302, and finally drive the two nut sleeves 11 to rotate synchronously. When the nut sleeve 11 is sleeved on the upper side of the double-headed threaded spike 8, as the direction of rotation of the nut sleeve 11 is different, the double-headed threaded spike 8 can be tightened in the HDPE sleeve 3, or the tightened double-headed threaded spike 8 can be loosened and separated from the HDPE sleeve 3.

[0104] Specifically, the lifting mechanism 15 includes:

[0105] The rack 1501 is fixedly connected to the other side of the protective shell 12;

[0106] The bearing frame 1502 is fixedly connected to the top of the base 1001;

[0107] An extension rod 1504 is rotatably connected to the bearing frame 1502, one end of which passes through the housing 1002 and is fixedly connected to a handle 1505; and

[0108] The spur gear 1503 is fixedly connected to the circumferential surface of the extension rod 1504 and meshes with the rack 1501 .

[0109] In a specific embodiment of the present invention, the handle 1505 is located close to the handrail 1005, and the bearing frame 1502 is used to support the extension rod 1504 for rotation. During operation, shaking the handle 1505 drives the extension rod 1504 to rotate, and the extension rod 1504 drives the spur gear 1503 to rotate. Under the action of meshing, the spur gear 1503 can drive the rack 1501 to rise and fall when it rotates, and the rack 1501 drives the protective shell 12 to rise and fall, and finally drives the nut sleeve 11 to rise and fall. When the nut sleeve 11 descends, it can be aligned with the double-headed threaded spike 8, and the nut sleeve 11 is sleeved on the upper side of the double-headed threaded spike 8. At this time, as the nut sleeve 11 rotates, the double-headed threaded spike 8 can be tightened in the HDPE sleeve 3, or the tightened double-headed threaded spike 8 can be loosened and separated from the HDPE sleeve 3, thereby realizing automatic installation and removal of the double-headed threaded spike 8. Preferably, the rack 1501 is a double rack and the spur gear 1503 is a double gear to increase structural strength and extend service life.

[0110] A method for manufacturing and using a track structure with prefabricated sleeve inverted arch blocks comprises the following steps:

[0112] S2. Add concrete raw materials into the casting hole 103 and wait for 24 hours to 48 hours;

[0113] S3. After the concrete solidifies, the mold body 1 and the prefabricated block body 2 are disassembled, and then the handle 503 is rotated to drive the positioning rod 5 to rotate, so that the threaded portion 501 is separated from the HDPE sleeve 3, and the HDPE sleeve 3 remains in the prefabricated block body 2, thereby obtaining the prefabricated block body 2 with the HDPE sleeve 3 embedded in it;

[0114] S4, loop S1-S3 to obtain multiple prefabricated block bodies 2;

[0115] S5. Install a pad 6 at each groove 201, arrange multiple prefabricated block bodies 2 linearly, and then install the track body 9 at the center of the multiple pads 6;

[0116] S6. Install a gauge baffle 7 at each prefabricated hole 202, with the side of the gauge baffle 7 close to the rail body 9 in contact with the rail bottom curved surface 901. Then, insert a double-headed threaded spike 8 through the gusset plate 701, the gauge baffle 7, and the prefabricated hole 202, and finally insert it into the HDPE sleeve 3.

[0117] S7. Place the assembly mechanism 10 on the track body 9 so that the track wheel 1003 can roll on the track body 9. Then control the output end of the servo motor 1304 to drive the large sprocket 1303 to rotate. Under the transmission action of the chain 1305, the small sprocket 1302 is driven to rotate synchronously. Then, the corresponding long shaft 1301 is driven to rotate, and finally the two nut sleeves 11 fixed thereto are driven to rotate synchronously.

[0118] S8. Shake the handle 1505 to rotate the extension rod 1504. The extension rod 1504 rotates the spur gear 1503, which in turn meshes with the rack 1501 and moves downward. Finally, the protective shell 12 and the nut sleeve 11 move downward synchronously, so that the two nut sleeves 11 are respectively sleeved on the upper side of the corresponding double-headed threaded spike 8. The double-headed threaded spike 8 is rotated by the nut sleeve 11, so that the double-headed threaded spike 8 is threadedly connected to the HDPE sleeve 3, thereby simultaneously fixing the backing plate 6, the gauge plate 7, and the track body 9, thereby improving installation efficiency.

[0119] S9. When the track body 9 needs to be disassembled, according to steps S7-S8, the output end of the servo motor 1304 is controlled to drive the large sprocket 1303 to rotate in the opposite direction, so as to drive the two nut sleeves 11 to rotate in the opposite direction. Then, the two nut sleeves 11 are respectively sleeved on the upper side of the corresponding double-headed threaded spikes 8. The double-headed threaded spikes 8 are driven by the nut sleeves 11 to rotate in the opposite direction, so that the double-headed threaded spikes 8 are gradually separated from the HDPE sleeve 3, thereby realizing the rapid disassembly of the double-headed threaded spikes 8.
