Description

Technical Field

[0001] This invention relates to the field of tunnel trolley equipment technology, and in particular to an automatic rail-feeding type hydraulic secondary lining trolley for tunnels. Background Technology

[0002] Lining trolleys are specialized equipment essential for secondary lining in tunnel construction, used for constructing the concrete lining of the tunnel's inner walls. Concrete lining trolleys are indispensable non-standard products in secondary lining during tunnel construction, mainly including simple lining trolleys, fully hydraulic automatic walking lining trolleys, and grid-type lining trolleys. Fully hydraulic lining trolleys can be further divided into side-top arch type, full-circular needle beam type, bottom-form needle beam type, and full-circular through-type, etc. In hydraulic tunnel and bridge construction, lifting slipform, jacking slipform, and flipping formwork are also commonly used.

[0003] In tunnel construction, lining trolleys inevitably require the construction of tracks and sleepers to allow them to move during tunnel construction. However, existing variable lining trolleys still have some shortcomings in their use:

[0004] 1. In the existing technology, when the lining trolley is moving, it is easy for it to slip on the slope when it encounters a certain slope. This not only affects the grouting accuracy of the lining trolley to the inner wall of the tunnel, but also makes it easy for the lining trolley to collide with personnel in the tunnel during the slippage, causing engineering accidents.

[0005] 2. Before the lining trolley is moved, the track needs to be moved. Because the track is relatively heavy and long, it is very difficult to move the track, and the guide rail is prone to deviation during the movement, causing the lining trolley to deviate from the predetermined position during the later movement.

[0006] To address the aforementioned problems, this invention proposes an automatic track-feeding type hydraulic secondary lining trolley for tunnels. Summary of the Invention

[0007] This invention provides an automatic track-feeding tunnel hydraulic lining trolley, which solves the shortcomings of existing technologies such as poor climbing performance, low safety, difficulty in track movement, and easy deviation of the guide rail.

[0008] This invention provides the following technical solution:

[0009] An automatic track-feeding type hydraulic tunnel lining trolley includes: a frame assembly and two tracks located below the frame assembly. The frame assembly has translational structures on both sides of its bottom.

[0010] The bottom of the translation structure is provided with multiple movable structures, and the outer side of the frame assembly is provided with a template assembly;

[0011] Translation structure, used to control the lifting and lowering of the frame assembly for translation;

[0012] A movable structure is used to move the frame assembly along a track.

[0013] In one possible design, the translation structure includes a platform fixedly connected to the bottom side of the frame assembly. Multiple movable structures are located below the platform. A first jack is fixedly connected to the top of each movable structure, and the output shaft of the first jack is fixedly connected to the bottom of the platform. Multiple guide rods are fixedly connected to the top of each movable structure, with the top ends of the guide rods sliding through the platform. Protrusions are fixedly connected to both sides of each movable structure, and translation cylinders are located on both sides of each movable structure. The output shafts of the translation cylinders are fixedly connected to one side of the protrusions. The extension and retraction of the first jack's output shaft controls the lifting and lowering of the frame assembly, facilitating the mating of the template assembly with the inner wall of the tunnel top. The extension and retraction of the translation cylinder's output shaft controls the left and right translation of the frame assembly, allowing the template assembly to mate with the inner wall of the tunnel side.

[0014] In one possible design, the moving structure includes a platform, with its top fixedly connected to the bottom of the moving structure. A translation cylinder is fixedly connected to the top of the platform. The track is located below the platform. Two first supports are fixedly connected to the bottom of the platform. Multiple rotating shafts rotatably pass through the two first supports. A traveling wheel that contacts the top of the track is fixedly fitted onto the outer wall of each rotating shaft. Multiple first sprockets are fixedly fitted onto the outer wall of each rotating shaft, and these first sprockets are connected by chain drive. A third sprocket is fixedly connected to both ends of one of the rotating shafts. Multiple rotating shafts rotatably pass through the two first supports. Second sprockets are fixedly fitted onto the outer walls of each of the multiple rotating shafts. Multiple third sprockets located on the same side... The two sprockets are connected by a chain drive. A rolling wheel extending into the track is fixedly connected to one end of the rotating shaft near the track. A fourth sprocket is connected to the outer wall of the third sprocket by a chain drive, and the fourth sprocket is fixedly connected to one end of one of the rotating shafts. The bottom of the platform is equipped with a braking structure to prevent slippage on slopes. The rotating shaft drives multiple traveling wheels to move on the track through the cooperation of the first sprocket and the chain, thereby controlling the frame assembly to move along the track trajectory, which facilitates the later tunnel lining. When the platform moves up a certain distance, the rolling wheel can lift the track, which can automatically complete the track transportation and laying. It is simple and convenient, requires no manual operation, reduces labor consumption, reduces labor intensity, saves work efficiency, and speeds up the construction progress.

[0015] In one possible design, the braking structure includes two second supports, which are rotatably sleeved on the outer wall of multiple rotating shafts. The top of the second supports is fixedly connected to the bottom of the platform. The two second supports are located on both sides of the traveling wheel. Multiple stops are fixedly connected to both sides of the top of the track. Multiple hydraulic locking structures are provided inside the second supports, and the hydraulic locking structures cooperate with the stops. The second supports can not only support the rotating shafts and traveling wheels, but also brake the frame assembly, translation structure, and moving structure to prevent slippage.

[0016] In one possible design, the hydraulic locking structure includes two hydraulic grooves disposed within a second bracket, connected by a hydraulic channel. Each hydraulic groove contains a slidably connected sealing plug. One sealing plug has multiple second springs fixedly connected to its bottom, and the bottoms of these second springs are fixedly connected to the same second trapezoidal block. The other sealing plug has multiple first springs fixedly connected to its bottom, and the bottoms of these first springs are fixedly connected to the same first trapezoidal block. Both the first and second trapezoidal blocks cooperate with a stop block. A cylinder is fixedly connected to the top inner wall of one of the hydraulic grooves, and the cylinder's output shaft is fixedly connected to the top of one of the sealing plugs. The extension and retraction of the cylinder's output shaft can move the first and second trapezoidal blocks up and down. When climbing an incline, the first trapezoidal block moves down, and the second trapezoidal block moves up. The cooperation between the first trapezoidal block and the stop block prevents slippage. When descending a slope, the first trapezoidal block moves up, and the second trapezoidal block moves down. The cooperation between the second trapezoidal block and the stop block also prevents slippage.

[0017] In one possible design, a horizontal box is fixedly connected to one side of one of the second supports. Floating plates are slidably connected to the inner walls of the horizontal boxes on opposite sides. A first pressure sensor and a second pressure sensor are fixedly embedded in the top inner wall of the horizontal box, and the first and second pressure sensors respectively cooperate with the two floating plates. Both the first and second pressure sensors are electrically connected to a cylinder. When the frame assembly is climbing an incline, the floating plates press against the first pressure sensor, the cylinder's output shaft is in a retracted state, and the first trapezoidal block moves downward to cooperate with a stop block. When the frame assembly is descending an incline, the floating plates press against the second pressure sensor, the cylinder's output shaft is in an extended state, and the second trapezoidal block moves downward to cooperate with a stop block.

[0018] In one possible design, a frame is fixedly connected to one side of the bottom of the platform, and a drive motor is fixedly connected to the inner wall of the bottom of the frame. The output shaft of the drive motor is fixedly connected to one of the third sprockets. By driving the third sprocket by the drive motor, the rotating shaft and the rotating shaft can be driven to rotate simultaneously. This can not only be used to move the frame assembly, but also to transport the track.

[0019] In one possible design, a second jack is fixedly connected to each of the four bottom corners of the platform, and the output shaft of the second jack is fixedly connected to a support pad. The extension and retraction of the output shaft of the second jack can lift the frame assembly and the translation structure, thereby disengaging the traveling wheels from the track, and can also be used for the rolling wheels to transport the track.

[0020] In one possible design, the top of the track is provided with a concave groove, which cooperates with the traveling wheel; when the output shaft of the second jack retracts, the traveling wheel falls into the concave groove, and the traveling wheel cooperates with the concave groove, thereby preventing displacement between the platform and the track when the traveling wheel falls into the concave groove, which would cause positional deviation between the frame assembly and the track.

[0021] In one possible design, an airbag is fixedly connected to one side of the bottom of the platform. The bottom of the airbag has a compression plate for squeezing it. The two sides of the compression plate are slidably connected to a first support and a second support, respectively. A compression rod for pushing the compression plate upwards is fixedly sleeved on the outer wall of the rotating shaft. Multiple nozzles are provided on the side of the first support near the track. An air guide pipe is provided on one side of each nozzle, with one end of the pipe passing through the first support and communicating with the airbag. One-way air inlet valves are provided on both sides of the airbag. The rotating shaft drives the compression rod to squeeze the airbag, and the gas inside the airbag is sprayed through the nozzles towards the top of the track, blowing off the concrete debris and small stones accumulated on the top of the track. This prevents the traveling wheels from crushing the concrete debris and small stones during movement, thus avoiding wear on the traveling wheels and track, affecting their service life, and preventing derailment of the traveling wheels and concave groove.

[0022] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the invention.

[0023] In this invention, sealing plugs are slidably connected to both hydraulic grooves. The bottom of one sealing plug is elastically connected to a second trapezoidal block via multiple second springs, and the bottom of the other sealing plug is elastically connected to a first trapezoidal block via multiple first springs. A cylinder is fixedly connected to the top inner wall of one of the hydraulic grooves, and the output shaft of the cylinder is fixedly connected to the top of one of the sealing plugs. The extension and retraction of the cylinder output shaft can drive the first and second trapezoidal blocks to rise and fall, thereby preventing the frame assembly from slipping on slopes and ensuring that the frame assembly remains stationary at a designated position, thus avoiding engineering accidents caused by slippage.

[0024] In this invention, multiple rotating shafts rotatably pass through the two first supports. Each of the rotating shafts has a third sprocket fixedly connected to both ends. Multiple rotating shafts also rotatably pass through the two first supports. A rolling wheel is fixedly connected to one end of each rotating shaft. A fourth sprocket is connected to the outer wall of each third sprocket via a chain drive, and the fourth sprocket is fixedly connected to one end of one of the rotating shafts. When the platform moves up a certain distance, the rolling wheel can lift the track, automatically completing the transport and laying of the track. This is simple and convenient, requiring no manual operation, reducing labor consumption, lowering labor intensity, saving efficiency, and accelerating construction progress.

[0025] In this invention, an airbag is fixedly connected to one side of the bottom of the platform. The bottom of the airbag is provided with a compression plate for squeezing the airbag. A compression rod for pushing the compression plate upward is fixedly sleeved on the outer wall of the rotating shaft. Multiple nozzles are provided on the side of the first bracket near the track. The nozzles are connected to the airbag through air guide pipes. The rotating shaft drives the compression rod to squeeze the airbag, and the nozzles remove debris from the top of the track, preventing the traveling wheels from crushing concrete debris and small gravel when the moving structure moves, which would cause wear on the traveling wheels and track, affect the service life of the traveling wheels and track, and cause the traveling wheels and concave groove to derail.

[0026] In this invention, float plates are slidably connected to the inner walls of the horizontal boxes on opposite sides. A first pressure sensor and a second pressure sensor are fixedly embedded in the top inner wall of the horizontal box, and the first and second pressure sensors are respectively engaged with the two float plates. Both the first and second pressure sensors are electrically connected to the cylinder. The extension and retraction of the cylinder can be controlled by the pressure of the float plates on the first and second pressure sensors. In turn, the frame assembly is braked on slopes by the cooperation of the first trapezoidal block, the second trapezoidal block and the stop block.

[0027] In this invention, the lifting and lowering of the frame assembly by the second jack can not only be used to move the frame assembly along the track, but also to transport and lay the track. It is simple and convenient, reduces labor consumption, lowers labor intensity, saves work efficiency, and speeds up construction progress. In addition, the extension and retraction of the cylinder output shaft controlled by the first and second pressure sensors can brake the frame assembly on slopes to prevent slippage.

The top of the second supports 22 is fixedly connected to the bottom of the platform 10 by bolts. The two second supports 22 are located on both sides of the traveling wheel 13. Multiple stops 31 are fixedly connected to the top sides of the track 2 by bolts. Multiple hydraulic locking structures are provided inside the second supports 22, and the hydraulic locking structures cooperate with the stops 31. The second supports 22 can not only support the rotating shafts 12 and the traveling wheel 13, but also brake the frame assembly 1, the translation structure 3 and the moving structure 4 to prevent slippage.

[0061] Reference Figure 4 , Figure 7 and Figure 8The hydraulic locking structure includes two hydraulic grooves 23 disposed within the second bracket 22, connected by a hydraulic channel 25. Each hydraulic groove 23 has a slidably connected sealing plug 24. One sealing plug 24 has multiple second springs 27 fixedly connected to its bottom, and the bottom of each second spring 27 is fixedly connected to the same second trapezoidal block 29. The other sealing plug 24 has multiple first springs 26 fixedly connected to its bottom, and the bottom of each first spring 26 is fixedly connected to the same first trapezoidal block 28. Both the first trapezoidal block 28 and the second trapezoidal block 29 cooperate with the stop block 31. A cylinder 30 is fixedly connected to the inner top wall of a hydraulic tank 23, and the output shaft of the cylinder 30 is fixedly connected to the inner top of one of the sealing plugs 24. The extension and retraction of the output shaft of the cylinder 30 can drive the first trapezoidal block 28 and the second trapezoidal block 29 to move up and down. When climbing, the first trapezoidal block 28 moves down and the second trapezoidal block 29 moves up. The cooperation between the first trapezoidal block 28 and the stop block 31 can prevent slippage. When descending, the first trapezoidal block 28 moves up and the second trapezoidal block 29 moves down. The cooperation between the second trapezoidal block 29 and the stop block 31 can prevent slippage.

[0062] Reference Figure 7 , Figure 8 and Figure 9 One of the second supports 22 has a horizontal box 32 fixedly connected to the top of one side. Floating plates 33 are slidably connected to the inner walls of the horizontal boxes 32 on opposite sides. A first pressure sensor 34 and a second pressure sensor 35 are fixedly embedded in the top inner wall of the horizontal box 32, and the first pressure sensor 34 and the second pressure sensor 35 are respectively engaged with the two floating plates 33. Both the first pressure sensor 34 and the second pressure sensor 35 are electrically connected to the cylinder 30. When the frame assembly 1 is climbing, the floating plate 33 presses against the first pressure sensor 34, the output shaft of the cylinder 30 is in a retracted state, and the first trapezoidal block 28 moves down to engage with the stop block 31. When the frame assembly 1 is descending, the floating plate 33 presses against the second pressure sensor 35, the output shaft of the cylinder 30 is in an extended state, and the second trapezoidal block 29 moves down to engage with the stop block 31.

[0063] Reference Figure 1 , Figure 4 and Figure 6 A frame 20 is fixedly connected to the bottom side of the platform 10. A drive motor 21 is fixedly connected to the bottom inner wall and the top inner wall of the frame 20. The output shaft of the drive motor 21 is fixedly connected to one of the third sprockets 18. By driving the third sprocket 18 through the drive motor 21, the rotating shaft 12 and the rotating shaft 14 can be driven to rotate simultaneously. This can not only be used to move the frame assembly 1, but also to transport the track 2.

[0064] Reference Figure 1 and Figure 4The bottom four corners of the platform 10 are all fixedly connected to the top of the second jack 42. The output shaft of the second jack 42 is fixedly connected to the top of the support pad 43. The extension and retraction of the output shaft of the second jack 42 can lift the frame assembly 1 and the translation structure 3, thereby disengaging the traveling wheel 13 from the track 2. It can also be used for the rolling wheel 15 to transport the track 2.

[0065] Reference Figure 2 and Figure 4 The top of the track 2 is provided with a concave groove 41, and the concave groove 41 cooperates with the traveling wheel 13; when the output shaft of the second jack 42 retracts, the traveling wheel 13 falls into the concave groove 41. The traveling wheel 13 cooperates with the concave groove 41, thereby preventing displacement between the platform 10 and the track 2 when the traveling wheel 13 falls into the concave groove 41, which would cause positional deviation between the frame assembly 1 and the track 2.

[0066] Reference Figure 4 , Figure 10 and Figure 11 An airbag 37 is fixedly connected to one side of the bottom of the platform 10. A compression plate 36 for squeezing the airbag 37 is located at the bottom of the airbag 37. The two sides of the compression plate 36 are slidably connected to the first support 11 and the second support 22, respectively. A compression rod 38 for pushing the compression plate 36 upward is fixedly sleeved on the outer wall of the rotating shaft 12. Multiple nozzles 40 are located on the side of the first support 11 near the track 2. An air guide pipe 39 is located on one side of each nozzle 40, and one end of the air guide pipe 39 passes through the first support 11 and connects to the airbag. The airbag 37 is connected to the ground, and one-way air intake valves are provided on both sides of the airbag 37. The rotating shaft 12 drives the squeezing rod 38 to squeeze the airbag 37. The gas in the airbag 37 is sprayed through the nozzle 40 to the top of the track 2, blowing off the concrete debris and small gravel accumulated on the top of the track 2. This prevents the traveling wheel 13 from crushing the concrete debris and small gravel when the moving structure 4 moves, which would cause wear on the traveling wheel 13 and the track 2, affect the service life of the traveling wheel 13 and the track 2, and cause the traveling wheel 13 and the concave groove 41 to derail.

[0067] A method for using an automatic track-feeding type hydraulic secondary lining trolley for tunnels:

[0068] S1. When it is necessary to move the track 2, the second jack 42 is activated. The extension of the output shaft of the second jack 42 lifts the frame assembly 1, the translation structure 3 and the moving structure 4 upward. The traveling wheel 13 disengages from the bottom inner wall of the concave groove 41. The rolling wheel 15 lifts the track 2 upward a certain distance. The track 2 is in a suspended state. The drive motor 21 is activated to drive one of the rotating shafts 12 to rotate. The rotating shaft 12 drives the rotating shaft 14 to rotate through the third sprocket 18 and the fourth sprocket 19. The rotating shaft 14 transports the track 2 to one side through the rolling wheel 15, completing the moving and laying of the track 2. It is simple and convenient, requires no manual operation, reduces labor consumption, reduces labor intensity, saves work efficiency and speeds up the construction progress.

[0069] S2. When the frame assembly 1 and the translation structure 3 need to be moved, the output shaft of the second jack 42 retracts, the traveling wheel 13 falls into the concave groove 41, the support pad 43 is separated from the ground, the drive motor 21 is started to drive one of the rotating shafts 12 to rotate, the rotating shaft 12 drives multiple traveling wheels 13 to rotate through the first sprocket 16, the traveling wheels 13 drive the frame assembly 1 and the track 2 to move along the track 2, and the traveling wheel 13 cooperates with the concave groove 41, so that when the traveling wheel 13 falls into the concave groove 41, it prevents the platform 10 and the track 2 from displacing, which would cause the frame assembly 1 and the track 2 to have positional deviations.

[0070] S3. When the frame assembly 1, the translation structure 3, and the moving structure 4 are in the climbing state, the horizontal box 32 tilts at a certain angle under the action of the second support 22. One of the floats 33 moves upward under the action of buoyancy and squeezes the first pressure sensor 34. At this time, the cylinder 30 is started. The output shaft of the cylinder 30 drives the sealing plug 24 above the second trapezoidal block 29 to move upward. The first trapezoidal block 28 moves downward under the action of the relative sealing plug 24 and cooperates with the stop block 31. Thus, when climbing, the locking cooperation between the first trapezoidal block 28 and the stop block 31 can prevent the frame assembly 1, the translation structure 3, and the moving structure 4 from slipping. Conversely, when going downhill, the other float 33 squeezes the second pressure sensor 35. The first trapezoidal block 28 and the second trapezoidal block 29 move upward and downward respectively. The cooperation between the second trapezoidal block 29 and the stop block 31 can once again prevent the slipping phenomenon, thus ensuring that the frame assembly 1, the translation structure 3, and the moving structure 4 are stationary at the designated position and preventing engineering accidents caused by slipping.

[0071] S4. In addition, when the lining trolley is in use, concrete debris and small stones are easily accumulated on the track 2. When the frame assembly 1, the translation structure 3 and the moving structure 4 are moving, the rotating shaft 12 drives the extrusion rod 38 to extrude the air bag 37. The gas in the air bag 37 is sprayed through the nozzle 40 to the top of the track 2, blowing off the concrete debris and small stones accumulated on the top of the track 2. This prevents the traveling wheel 13 from crushing the concrete debris and small stones when the moving structure 4 is moving, which would cause wear on the traveling wheel 13 and the track 2, affect the service life of the traveling wheel 13 and the track 2, and cause the traveling wheel 13 and the concave groove 41 to derail.

[0072] However, as is well known to those skilled in the art, the working principles and wiring methods of the first pressure sensor 34, the second pressure sensor 35, the cylinder 30, the drive motor 21, the support pad 43, the translation cylinder 8, and the first jack 5 are commonplace and belong to conventional means or common knowledge.
