Abstract
Description
Technical Field
[0001] The present invention relates to the field of railway construction, and in particular to a construction device and a construction method for a multi-track railway in a tunnel. Background Art
[0002] In the reconstruction and expansion of multi-track railways in tunnels, traditional construction methods often rely on D-type temporary beams as temporary support structures. However, this method has exposed many shortcomings in practical applications. First, the installation of D-type temporary beams requires large-scale lifting equipment to be opened near the tunnel, and the space above the tunnel is limited, making it difficult for equipment to enter the site, which increases the difficulty and cost of construction. Secondly, in order to ensure the installation position of the D-type temporary beam, it is often necessary to remove part or all of the power-off contact network, which not only affects the normal operation of the railway, but also increases the complexity of construction and safety risks. More importantly, the connection accuracy of the crossbeam and vertical beam of the D-type temporary beam is extremely high. Once the connection is misaligned, it will take a lot of time to dismantle and reinstall, which seriously restricts the progress of construction. Therefore, it is particularly important to seek a more efficient, flexible and non-affective construction method for multi-track railways in tunnels.
[0003] For example, the Chinese invention patent CN113832947A discloses a "reinforcement device and method for a shield tunnel passing under a railway with multiple tracks with small spacing". Its specification discloses that the contact network above the track is usually powered off or even removed to temporarily expand the scope of the railway line control area to create conditions for the construction of the temporary beam foundation. Although this method can effectively avoid the relevant technical problems caused by the construction of traditional D-type temporary beams, the relevant procedures for powering off or removing the contact network, as well as the land acquisition issues that may be involved in expanding the railway line control area, lead to a long construction period and increase in uncontrollable factors, which seriously affect railway transportation; and in the face of railway lines with small track spacing and a large number of tracks, it is difficult for the D-type construction temporary beam foundation to have a landing space; the above patent can prove the defects of the existing technology.
[0004] Therefore, we make improvements to this and propose a construction equipment and construction method for multi-track railways in a tunnel. Summary of the invention
[0005] The purpose of the present invention is to address the current situation that the space above the tunnel is limited, the equipment is difficult to enter, and there is misalignment, which will take a lot of time to dismantle and reinstall, and it is necessary to dismantle part or all of the contact network that needs to be powered off.
[0006] In order to achieve the above-mentioned purpose of the invention, the present invention provides the following construction equipment and construction method for multi-track railway in a tunnel to improve the above-mentioned problems.
[0007] The specific application is as follows: A construction equipment for a tunnel multi-track railway, comprising a base and a top cover installed on the top outer wall thereof, wherein the base is rotatably connected to a side plate via a rotating shaft. It should be supplemented that the rotation positions of the side plates on both sides of the base are not on a plane perpendicular to the base, that is, when the two bases are used in combination, it is necessary to misalign the two side plates in different directions so that the side plate on one side of one base forms a coupled connection portion inside the side plate of the other base, a plurality of connection holes are opened on the side plates, a driving device is arranged inside the base, a limiting device is arranged on the base, the driving device comprises a driving motor fixedly connected to the inner wall of the base, it should be supplemented that the driving motor is a double-headed motor, that is, the main rotating shaft extends to both sides of the driving motor, the driving motor is fixedly connected to the main rotating shaft via a coupling, a plurality of stirring plates are fixedly connected to the inside of the main rotating shaft, the plurality of stirring plates form a cage structure for transporting debris during the rotation of the main rotating shaft, and a fixing ring is fixedly connected to the main rotating shaft.
[0008] As a preferred technical solution of the present application, the driving device further comprises a plurality of L-shaped plates fixedly connected to a fixing ring, a plurality of friction plates fixedly connected to the fixing ring, and a threaded portion fixedly connected to the main shaft.
[0009] As a preferred technical solution of the present application, the driving device also includes a threaded sleeve threadedly connected to the threaded part, and a special-shaped wheel is rotatably connected to the threaded sleeve, and the special-shaped wheel is provided with a plurality of one-way friction grooves, the special-shaped wheel is provided with a plurality of deep grooves, and the special-shaped wheel is provided with a plurality of arc surface grooves, and the arc surface grooves are positioned adjacent to the deep grooves.
[0010] As a preferred technical solution of the present application, the driving device also includes a plurality of first clamping rods hinged to the special-shaped wheels, a positioning ring is rotatably connected to the main shaft through a bearing, a plurality of second clamping rods are hinged on the positioning ring, the second clamping rods are a double-layer structure, and a hinge point is arranged between the first clamping rod and the second clamping rod.
[0011] As a preferred technical solution of the present application, the driving device also includes an empty ring arranged on the threaded part, and a plurality of telescopic parts are fixedly connected to the empty ring. One end of the telescopic part away from the empty ring is hinged to the hinge point between the first clamping rod and the second clamping rod, and the empty ring does not contact the threaded part.
[0012] As a preferred technical solution of the present application, the limiting device includes a rotating circular plate rotatably connected to both sides of the base, both ends of the rotating circular plate are fixedly connected to fixed bars, two connecting plates are fixedly connected to the rotating circular plate, two fan-shaped plates are rotatably connected to the rotating circular plate, and a single fan-shaped plate is fixedly connected to an arc panel, and a crescent groove is provided on the arc panel.
[0013] A method for constructing a multi-track railway in a tunnel comprises the following steps: S1. Assisted trench digging. After removing the gravel under the track, the centerline trench between the gaps in the middle of the two rail sleepers is cleaned out. The cross plate of the equipment needs to be removed from the two connecting plates. At this time, the fan-shaped plate and the arc plate are exposed on both sides of the base. When it is difficult for personnel to work under the railway, the equipment is pushed toward the direction of the complex road surface. It should be noted that the push plate needs to be set in the cavity inside the base to ensure that the push plate does not contact the grooves on both sides during rotation. The special-shaped wheel is displaced by the action of the thread and the groove and the first clamp rod and the second clamp rod, and finally misaligned with the threaded part. The telescopic part operates to make the special-shaped wheel contact the fixed ring through the deep groove and the L-shaped plate. It should be added that At this time, the rotation direction of the fixed ring is from the deep groove to the arc groove. At this time, the fixed ring can drive the first clamping rod and the second clamping rod to move synchronously. Since the push plate will provide centrifugal force and thrust in the tangential direction of the main shaft during the rotation process, the torque of the main shaft is indirectly increased. At this time, the main shaft drives the rotating circular plate to rotate, so that the fan-shaped structure composed of the fan-shaped plate and the arc plate rotates and transports the impurities on the road surface to the inside through the crescent groove under the push of manpower. At this time, the impurities move to the internal space of the main shaft through the fan-shaped groove. At this time, the main shaft rotates, and the impurities will produce a cage effect through the internal stirring plate and the internal space of the main shaft. At this time, the impurities will be transported from one end of the base to the other end through the structure, which is more convenient for collecting or transporting impurities. S2. Calibrate the spacing between the crossbeams. When the equipment is already between two rail sleepers, the space on both sides of the base is exposed by rotating the side plates. Since the side plates can only rotate in a direction perpendicular to the base as a guide for the subsequent push plates and complete the calibration effect, the drive motor reverses and moves to the direction of the deep groove and then stops rotating. The telescopic part works to make the hinged part of the first clamping rod and the second clamping rod extend outward. At this time, the first clamping rod and the second clamping rod are in contact with the groove on the base. At the same time, the L-shaped plate on the fixing ring is separated by the deep groove on the special-shaped wheel and then contacts the threaded part. At this time, the threaded sleeve is driven by the drive motor to restore the threaded connection with the threaded part. At this time, the threaded part pushes the special-shaped wheel to make a linear motion through the threaded sleeve. Since the special-shaped wheel and the threaded sleeve are rotationally connected, the special-shaped wheel will not rotate. At this time, the first clamping rod and the second clamping rod move outward and finally push the push plate to both sides of the sleeper to achieve the effect of aligning the two sides of the sleeper and installing them with the vertical beam. Moreover, the calibration effect can be used before or after the auxiliary trench excavation step.
[0014] As the preferred technical solution of this application, it also includes: S3. Monitor stress changes. When the trench excavation is completed and the positioning effect is produced, the equipment can be placed in the trench instead of the crossbeam to test the stress change in this section. After the telescopic part pulls the first clamp rod and the second clamp rod back to the space inside the base, the fixing ring and the special-shaped wheel are selected to be re-contacted and the positions of the first clamp rod and the second clamp rod are adjusted to a vertical state. At this time, the telescopic part is re-operated to push the first clamp rod and the second clamp rod to contact with the top and bottom of the base to form a buffer area. A pressure sensor can be set between the fixing ring and the special-shaped wheel. When the top senses stress, the first clamp rod and the second clamp rod will push the special-shaped wheel to move laterally and transmit the stress to the sensor. In addition, the buffer structure can enhance the stability of the base.
[0015] As the preferred technical solution of this application, it also includes: S4. Measure the connection of the workpiece. In the existing construction plan, there is a method that requires the horizontal beam and the vertical beam to be connected. In the existing structure, the rotating circular plate can be rotated in conjunction with the drive of the driving motor. There is a mounting strip on the traditional vertical beam that cooperates with the corbel and the mounting parts to connect with the horizontal beam. Now, by setting the mounting strip on the vertical beam between the two vertically arranged fan-shaped plates, and by rotating the rotating circular plate, the two connecting plates are in contact with and aligned with the mounting strip on the vertical beam, so that pre-calibration can be performed in advance during the installation process to prevent the installation holes from being misaligned during the installation process, which requires a lot of time for reassembly. At the same time, the driving motor can provide an inward squeezing force, which can better prevent the equipment from being detached from the vertical beam. At the same time, the connection between the fan-shaped plate and the connecting plate is released so that the fan-shaped plate is connected to the fixed strip through the mounting hole, so that the structure can completely provide the mounting strip on the vertical beam with uniform force on both sides to prevent lateral stress from causing hardware damage.
[0016] As the preferred technical solution of this application, it also includes: S5. Assisted transportation of vertical beams. Construction sites often have the problem of large operating machines being difficult to enter, which makes it difficult to transport them to the construction site through mechanical operations. In addition, since mechanical operations require the closure of the contact network, the construction time is prolonged. The cross plate can be installed in the cross groove formed by the connecting plate and the fan-shaped plate and connected through connecting parts to provide a transportation effect. It should be added that the apex of the wheel portion shall not exceed the top surface of the top cover. At this time, two identical devices are alternately connected through the side plate at a ninety-degree angle to the base and the side plate of the next device. At the same time, a cross beam is used to be installed with the vertical beam through the connecting parts, and the cross beam is placed on the top of the top cover. The operation of the drive motor can be used for auxiliary transportation, and the vertical beam can be transported out or into the construction site.
[0017] Compared with the prior art, the present invention has the following beneficial effects: In the scheme of this application: 1. In order to solve the problem that it is difficult to handle the space at the bottom of the track during on-site construction in the prior art, the present application realizes the cooperation with the workpiece outside the base through the setting of the driving device, and realizes the transportation of impurities and soil and other materials that are difficult to be handled manually to both sides of the track through the rotation of the workpiece through the operation of the equipment, so as to facilitate recycling; 2. In order to solve the problem of calibrating the spacing between beams in the prior art, the present application realizes the outward movement of the workpieces on both sides of the unfolding device to the sleepers on both sides through the setting of the driving device and finally determines the centerline position, that is, to prevent the deviation problem in the grooving process and prevent the position deviation in the subsequent connection process; 3. The strength of the base is enhanced by setting a driving device, and a buffer structure is set in the base. When stress occurs, the stress can be transmitted to the sensor through buffering and the stress can be detected. At the same time, the base is damaged by strong stress, which solves the problem that the stress change cannot be mastered in the prior art; 4. The drive device is provided to achieve pre-alignment between the vertical beam and the horizontal beam, solving the problem in the prior art that a lot of time is required to remove the connector after misalignment occurs; 5. By setting the limit device, the effect of assisting manpower to transport the vertical beam is achieved, which solves the problem in the prior art that the vertical beam is difficult to transport by mechanical equipment and the contact network needs to be processed.

[0021] As described in the background technology, the space above the tunnel is limited, and it is difficult for equipment to enter the site.

It should be supplemented that the driving motor 501 is a double-headed motor, that is, the main shaft 502 extends to both sides of the driving motor 501, and the driving motor 501 is fixedly connected to the main shaft 502 through a coupling.

[0024] The present invention provides a tunnel multi-track railway construction equipment, which uses a main rotating shaft 502 that drives through the overall base 1, and uses its external threaded structure as a driving component to push the push plate 515 open to form a positioning structure. At the same time, its internal stirring blade 503 acts as a material transport component to transport debris on the railway from one end to the other during the rotation process.
[0025] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.
[0026] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.
[0027] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.
[0028] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 , a construction method for multiple railways in a tunnel, the driving device 5 also includes a plurality of L-shaped plates 505 fixedly connected to a fixing ring 504, a plurality of friction plates 506 fixedly connected to the fixing ring 504, and a threaded portion 507 fixedly connected to the main rotating shaft 502.
[0029] The use of the L-shaped plate 505 and the friction plate 506 can make the friction and contact between the special-shaped wheel 509 and the fixed ring 504 closer, so that the fixed ring 504 can drive the special-shaped wheel 509 to rotate in a certain state during the rotation process.
[0030] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 A construction method for a multi-track railway in a tunnel, wherein the driving device 5 also includes a threaded sleeve 508 threadedly connected to a threaded portion 507, a special-shaped wheel 509 rotatably connected to the threaded sleeve 508, a plurality of one-way friction grooves 5091 are provided on the special-shaped wheel 509, a plurality of deep grooves 510 are provided on the special-shaped wheel 509, and a plurality of arc surface grooves 511 are provided on the special-shaped wheel 509, and the arc surface grooves 511 are located adjacent to the deep grooves 510.
[0031] The threaded sleeve 508 is used to perform simple linear motion, so that the first clamping rod 512 and the second clamping rod 514 are unfolded and unfolded from the base 1, and then contact the sleepers on both sides to produce a positioning effect.
[0032] Example 2 further optimizes the construction method of a tunnel multi-track railway provided in Example 1. Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, the driving device 5 also includes a plurality of first clamping rods 512 hinged to the special-shaped wheel 509, a positioning ring 513 is rotatably connected to the main shaft 502 through a bearing, a plurality of second clamping rods 514 are hinged to the positioning ring 513, the second clamping rod 514 is a double-layer structure, and a hinge point is set between the first clamping rod 512 and the second clamping rod 514.
[0033] The first clamping rod 512 and the second clamping rod 514 form a telescopic structure, thereby generating a pushing effect. Meanwhile, during the rotation process, the clamping rod is also connected to a push plate 515, so the torque can be increased during the rotation process.
[0034] Further, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 and Fig.10 As shown, the driving device 5 also includes an empty ring 516 arranged on the threaded portion 507, and a plurality of telescopic portions 517 are fixedly connected to the empty ring 516. One end of the telescopic portion 517 away from the empty ring 516 is hinged to the hinge point between the first clamping rod 512 and the second clamping rod 514, and the empty ring 516 does not contact the threaded portion 507.
[0035] The hollow ring 516 is provided above the main rotating shaft 502 without contacting the main rotating shaft 502 to provide pulling and pushing forces in the inner and outer directions, so that the first clamping rod 512 and the second clamping rod 514 can produce the effects of contraction and extension.
[0036] The limiting device 6 includes a rotating circular plate 601 rotatably connected to both sides of the base 1, both ends of the rotating circular plate 601 are fixedly connected with fixed bars 602, two connecting plates 603 are fixedly connected to the rotating circular plate 601, two fan-shaped plates 604 are rotatably connected to the rotating circular plate 601, a single fan-shaped plate 604 is fixedly connected with an arc panel 605, and a crescent groove 6051 is opened on the arc panel 605.
[0037] By using the arc panel 605, the fan-shaped plate 604 and the crescent groove 6051, the two sides of the end of the base 1 can rotate, and a crushing effect can be produced during the rotation and stop process, so that the device can be better placed under the track during the advancement process.
[0038] The limiting device 6 also includes a plurality of mounting holes 606 provided on the fixing strip 602, the connecting plate 603 and the fan-shaped plate 604. A cross plate 608 is provided on the connecting plate 603. A wheel hub 609 is fixedly connected to the cross plate 608. A tow bar anti-stuck plate 610 is fixedly connected to the wheel hub 609. A wheel portion 611 is fixedly connected to the wheel hub 609.
[0039] The mounting hole 606 is used to fix the rotation position of the sector plate 604 on the rotating circular plate 601, and plays a corresponding role after the position is fixed.
[0040] Example 3, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 , a construction method for a multi-track railway in a tunnel, comprising: S1, auxiliary trench digging, after removing the gravel under the track, clean up the centerline trench at the gap position between the two track sleepers, it is necessary to remove the cross plate 608 of the equipment from the position of the two connecting plates 603, at this time the fan plate 604 and the arc plate 605 are exposed on both sides of the base 1, when it is difficult for personnel to construct under the railway, push the equipment to move in the direction of the complex road surface, it should be noted that it is necessary to ensure that the push plate 515 is arranged in the cavity inside the base 1, to ensure that the push plate 515 does not contact the grooves on both sides during the rotation process, the special-shaped wheel 509 is displaced by the action of the first clamping rod 512 and the second clamping rod 514 through the thread and the groove, and finally misaligned with the threaded part 507, the telescopic part 517 operates to make the special-shaped wheel 509 contact with the fixing ring 504 through the deep groove 510 and the L-shaped plate 505, it should be added that at this time the fixing ring 5 04 rotates in the direction from the deep groove 510 to the arc groove 511. At this time, the fixed ring 504 can drive the first clamping rod 512 and the second clamping rod 514 to move synchronously. Since the push plate 515 provides centrifugal force and thrust in the tangential direction of the main shaft 502 during the rotation process, the torque of the main shaft 502 is indirectly increased. At this time, the main shaft 502 drives the rotating circular plate 601 to rotate, so that the fan-shaped structure composed of the fan-shaped plate 604 and the arc plate 605 rotates and transports the impurities on the road surface to the inside through the crescent groove 6051 under the push of manpower. At this time, the impurities move to the inner space of the main shaft 502 through the fan-shaped groove 607. At this time, the main shaft 502 rotates, and the impurities will produce a cage effect through the internal stirring piece 503 and the internal space of the main shaft 502. At this time, the impurities will be transported from one end of the base 1 to the other end through the structure, which is more convenient for collecting or transporting impurities. S2. Calibrate the spacing between the beams. When the device is already between two rail sleepers, the space on both sides of the base 1 is exposed by rotating the side panels 3. Since the side panels 3 can only be rotated in a direction perpendicular to the base 1, they serve as guides for the subsequent push plates 515 and complete the calibration effect. At the same time, the drive motor 501 reverses and moves to the direction of the deep groove 510 and then stops rotating. The telescopic portion 517 works to extend the hinged portion of the first clamping rod 512 and the second clamping rod 514 outward. At this time, the first clamping rod 512 and the second clamping rod 514 are in contact with the grooves on the base 1. At the same time, the L-shaped plate 505 on the fixing ring 504 is moved by the special-shaped wheel 509. After the deep groove 510 is separated, it contacts the threaded portion 507. At this time, the driving motor 501 drives the rear threaded sleeve 508 to restore the threaded connection with the threaded portion 507. At this time, the threaded portion 507 pushes the special-shaped wheel 509 to make a linear motion through the threaded sleeve 508. Since the special-shaped wheel 509 and the threaded sleeve 508 are rotationally connected, the special-shaped wheel 509 will not rotate. At this time, the first clamping rod 512 and the second clamping rod 514 move outward and finally push the push plate 515 to both sides of the sleeper to achieve the effect of aligning the two sides of the sleeper and installing it with the vertical beam, and this calibration effect can be used before or after the auxiliary trench excavation step.
[0041] S3. Monitor stress changes. After the trench excavation is completed and the positioning effect is produced, the equipment can be placed in the trench instead of the beam to test the stress change in this section. After the telescopic part 517 pulls the first clamping rod 512 and the second clamping rod 514 back to the space inside the base 1, the fixing ring 504 and the special-shaped wheel 509 are selected to be re-contacted and the positions of the first clamping rod 512 and the second clamping rod 514 are adjusted to a vertical state. At this time, the telescopic part 517 is re-operated to push the first clamping rod 512 and the second clamping rod 514 to contact with the top and bottom of the base 1 to form a buffer area and a pressure sensor can be set between the fixing ring 504 and the special-shaped wheel 509. When the top senses stress, the first clamping rod 512 and the second clamping rod 514 will push the special-shaped wheel 509 to move laterally and transmit the stress to the sensor, and the buffer structure can enhance the stability of the base 1.
[0042] S4. Measure the connection of the workpiece. In the existing construction plan, there is a method that requires the horizontal beam and the vertical beam to be connected. In the existing structure, the rotating circular plate 601 can be rotated in conjunction with the drive of the driving motor 501. There is a mounting strip on the traditional vertical beam to cooperate with the corbel and the mounting parts to connect with the horizontal beam. Now, by setting the mounting strip on the vertical beam between the two vertically arranged fan-shaped plates 604, and by rotating the rotating circular plate 601, the two connecting plates 603 are in contact with and aligned with the mounting strip on the vertical beam, so that pre-calibration can be performed in advance during the installation process to prevent the installation holes from being misaligned during the installation process, which requires a lot of time for reassembly. At the same time, the driving motor 501 can provide an inward squeezing force, which can better prevent the equipment from being separated from the vertical beam. At the same time, the connection between the fan-shaped plate 604 and the connecting plate 603 is released so that the fan-shaped plate 604 is connected to the fixed strip 602 through the mounting hole 606, so that the structure can completely provide the mounting strip on the vertical beam with uniform force on both sides to prevent lateral stress from causing hardware damage.
[0043] S5. Assisted transportation of vertical beams. Construction sites often have the problem of large operating machines being difficult to enter, which makes it difficult to transport them to the construction site through mechanical operations. In addition, since mechanical operations require the closure of the contact network, the construction time is prolonged. The cross plate 608 can be installed in the cross groove formed by the connecting plate 603 and the fan-shaped plate 604 and connected through the connecting piece to provide a transportation effect. It should be added that the top of the wheel part 611 must not exceed the top surface of the top cover 2. At this time, two identical devices are alternately connected through the side plate 3 at a ninety-degree angle to the base 1 and the side plate 3 of the next device. At the same time, a cross beam is used to be installed with the vertical beam through the connecting piece, and the cross beam is placed on the top of the top cover 2. The operation of the drive motor 501 can be used for auxiliary transportation, and the vertical beam can be transported out or into the construction site.

7. A method for constructing a multi-track railway in a tunnel, using the construction equipment for a multi-track railway in a tunnel as claimed in claim 6, characterized in that: The following steps are involved: S1. Auxiliary trench excavation. After removing the gravel under the track, a centerline trench is cleared at the gap between the two rail sleepers. The cross plate (608) of the device needs to be removed from the two connecting plates (603). At this time, the fan plate (604) and the arc plate (605) are exposed on both sides of the base (1). When it is difficult for personnel to work under the railway, the device is pushed to move in the direction of the complex road surface. It should be noted that the push plate (515) needs to be set inside the base (1). The push plate (515) is ensured not to come into contact with the grooves on both sides during the rotation process. After the shaped wheel (509) is displaced by the action of the thread and the groove and the first clamping rod (512) and the second clamping rod (514), and finally misaligned with the threaded portion (507), the telescopic portion (517) operates to make the shaped wheel (509) come into contact with the fixing ring (504) through the deep groove (510) and the L-shaped plate (505). It should be added that at this time, the fixing ring (504) ) is rotated in the direction from the deep groove (510) to the arc groove (511). At this time, the fixing ring (504) can drive the first clamping rod (512) and the second clamping rod (514) to move synchronously. Since the push plate (515) provides centrifugal force and thrust in the tangential direction of the main rotating shaft (502) during the rotation process, the torque of the main rotating shaft (502) is indirectly increased. At this time, the main rotating shaft (502) drives the rotating circular plate (601) to rotate, so that the sector plate (604) and the arc plate (605) are The fan-shaped structure rotates and transports impurities on the road surface to the inside through the crescent groove (6051) under the push of human power. At this time, the impurities move to the internal space of the main rotating shaft (502) through the fan-shaped groove (607). At this time, the main rotating shaft (502) rotates, and the impurities pass through the internal stirring blade (503) and the internal space of the main rotating shaft (502) to produce a cage effect. At this time, the impurities are transported from one end of the base (1) to the other end through the structure, making it easier to collect or transport impurities. S2. Calibrate the beam spacing. When the device is already between two rail sleepers, the space on both sides of the base (1) is exposed by rotating the side plates (3). Since the side plates (3) can only be rotated in a direction perpendicular to the base (1) to serve as a guide for the subsequent push plate (515) and complete the calibration effect, the drive motor (501) is reversed and moves to the direction of the deep groove (510) and then stops rotating. The telescopic part (517) works to make the hinge part of the first clamping rod (512) and the second clamping rod (514) extend outward. At this time, the first clamping rod (512) and the second clamping rod (514) are in contact with the groove on the base (1). At the same time, the L-shaped plate (505) on the fixing ring (504) is rotated by the special-shaped wheel (509). After the deep groove (510) on the sleeper is separated, it contacts the threaded portion (507). At this time, the driving motor (501) drives the rear threaded sleeve (508) to restore the threaded connection with the threaded portion (507). At this time, the threaded portion (507) pushes the special-shaped wheel (509) to make a linear motion through the threaded sleeve (508). Since the special-shaped wheel (509) and the threaded sleeve (508) are rotationally connected, the special-shaped wheel (509) will not rotate. At this time, the first clamping rod (512) and the second clamping rod (514) move outward and finally push the push plate (515) to both sides of the sleeper to achieve the effect of aligning the two sides of the sleeper and installing them with the vertical beam, and this calibration effect can be used before or after the step of auxiliary trench excavation.
8. A method for constructing a multi-track railway in a tunnel according to claim 7, characterized in that: Also includes: S3, monitoring stress changes. When the trench is excavated and the positioning effect is achieved, the device can be placed in the trench instead of the crossbeam to test the stress change at this section. After the telescopic part (517) pulls the first clamping rod (512) and the second clamping rod (514) back to the space inside the base (1), the fixing ring (504) and the special-shaped wheel (509) are selected to be in contact again and the positions of the first clamping rod (512) and the second clamping rod (514) are adjusted to a vertical state. At this time, the telescopic part (517) is operated again to push the first clamping rod (512) and the second clamping rod (514) to contact the top and bottom of the base (1) to form a buffer area. A pressure sensor can be set between the fixing ring (504) and the special-shaped wheel (509). When the top senses stress, the special-shaped wheel (509) is pushed to move laterally through the first clamping rod (512) and the second clamping rod (514) and the stress is transmitted to the sensor. In addition, the buffer structure can enhance the stability of the base (1).
9. A method for constructing a multi-track railway in a tunnel according to claim 8, characterized in that: Also includes: S4. Measure the connection of the workpiece. In the existing construction scheme, there is a method that requires the horizontal beam and the vertical beam to be connected. In the existing structure, the rotating circular plate (601) can be rotated in conjunction with the drive motor (501). There is a mounting strip on the traditional vertical beam that cooperates with the bracket and the mounting piece to connect with the horizontal beam. Now, by setting the mounting strip on the vertical beam between two vertically arranged fan-shaped plates (604), and by rotating the rotating circular plate (601), the two connecting plates (603) can be brought into contact with and aligned with the mounting strip on the vertical beam. , so that pre-calibration can be performed in advance during the installation process to prevent the installation holes from being misaligned during the installation process, which would require a lot of time for reassembly. At the same time, the drive motor (501) can provide an inward squeezing force to better prevent the device from being separated from the vertical beam. At the same time, the connection between the fan-shaped plate (604) and the connecting plate (603) is released so that the fan-shaped plate (604) is connected to the fixing bar (602) through the installation hole (606), so that the structure can completely provide the installation bar on the vertical beam with uniform force on both sides, thereby preventing lateral stress from causing damage to the hardware.
10. A method for constructing a multi-track railway in a tunnel according to claim 9, characterized in that: Also includes: S5. Assisted transportation of vertical beams. Construction sites often have the problem of large-scale operating machines being difficult to enter, which makes it difficult to transport large quantities of equipment to the construction site by mechanical operation. In addition, since mechanical operation requires the shutdown of the contact network, the construction time is prolonged. The cross plate (608) can be installed in the cross groove formed by the connecting plate (603) and the fan-shaped plate (604) and connected by a connecting piece to provide a transportation effect. It should be added that the top of the wheel portion (611) must not exceed the top surface of the top cover (2). At this time, two identical devices are alternately connected by a side plate (3) at a ninety-degree angle to the base (1) and the side plate (3) of the next device. At the same time, a cross beam is used to be installed with the vertical beam through a connecting piece, and the cross beam is placed on the top of the top cover (2). The operation of the drive motor (501) can be used for auxiliary transportation, and the vertical beam can be transported out of or into the construction site.
