Description

Technical Field

[0001] The present invention relates to the technical field of ice-breaking devices, and particularly relates to a railway tunnel ice-breaking device and an ice-breaking method. Background Art

[0002] The tunnel vault is in the shape of an arc. Water mist is likely to accumulate moisture at the tunnel vault and is easy to freeze in cold weather. After the tunnel vault freezes, it poses a great safety hazard to passers-by and vehicles passing through the tunnel.

[0003] Chinese Patent CN219932182U discloses a tunnel vault de-icing device. By rotating the steel wire ice-breaking brush, ice bodies such as ice surfaces and ice cones can be polished and removed. After the pedal reaches the bottom, the return spring is compressed, and the pedal can return to the initial position under the action of the return spring, and then the next de-icing operation can be carried out.

[0004] The above device can process the ice columns on the inner wall of the tunnel through the set steel wire ice-breaking brush. However, for some thicker ice columns or thicker ice layers, it is more laborious to break the ice through the above structure. In addition, since the tunnel vault is mostly arc-shaped, the operation of this device is also more inconvenient. In summary, the above device still has room for improvement.

[0005] Therefore, it is necessary to provide a railway tunnel ice-breaking device and an ice-breaking method to solve the above technical problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a railway tunnel ice-breaking device and an ice-breaking method to solve the problem that the existing device can process the ice columns on the inner wall of the tunnel through the set steel wire ice-breaking brush, but it is more laborious to break the ice through the above structure for some thicker ice columns or thicker ice layers as mentioned in the above background art.

[0007] Based on the above idea, the present invention provides the following technical solution: A railway tunnel ice-breaking device includes a support plate and a vertical rod arranged above the support plate. A cutting plate is fixedly arranged at the top of the vertical rod. A second vertical plate is fixedly installed on the top surface of the support plate. A rotating rod is installed on one side of the second vertical plate close to the vertical rod. A U-shaped frame is fixedly arranged at the top of the rotating rod. Pressure strips are hinged on both sides of the frame. The pressure strips can deflect along a single direction relative to the frame.

A rotating shaft is slidably assembled on the side of the vertical rod away from the sliding rod. A spur gear is fixedly sleeved on the outer side of the rotating shaft. Two sets of transmission teeth meshing with the spur gear are arranged on one side of the bottom of the driving frame. The rotating shaft is connected to the cutting knife through a vibration assembly. When the rotating shaft is driven to rotate by the meshing of the transmission teeth and the spur gear, the rotating shaft can cause the cutting knife to reciprocate relative to the cutting plate through the vibration assembly.

[0008] As a further scheme of the present invention: The driving assembly includes a sleeve. The sleeve is sleeved on the outer sides of the rotating shaft and the sliding rod, and the rotating shaft can drive the sleeve to rotate synchronously. A plurality of protrusions are fixedly arranged on the outer peripheral wall of the sleeve. The vertical rod is elastically connected with a pressing rod, and the pressing rod is arranged along the length direction of the vertical rod. One side of the top of the pressing rod is set as an inclined extrusion surface. A roller is arranged on the extrusion surface. The two cutting knives are connected through a connecting strip. The roller is matched with one of the connecting strips through a bracket. The bottom end of the pressing rod extends to the outer peripheral wall of the sleeve.

[0009] As a further scheme of the present invention: A boss is arranged on the side of the vertical rod close to the frame body. The vertical rod is elastically connected with a plug-in block, and the plug-in block is set as a T shape. An annular groove matched with the plug-in block is opened on the outer peripheral wall of the sliding rod.

[0010] As a further scheme of the present invention: A first vertical plate is fixedly installed on the top surface of the support plate. The vertical rod is rotationally matched with the first vertical plate. An arc-shaped groove is opened on the first vertical plate. A slider is slidably installed in the arc-shaped groove. The slider is fixedly connected with the vertical rod. A plurality of clamping grooves are uniformly opened on the top wall of the inner cavity of the arc-shaped groove. Two clamping blocks are elastically connected to the slider. The clamping blocks are matched with the clamping grooves. The opposite surfaces of the two clamping blocks are both set as inclined surfaces.

[0011] As a further scheme of the present invention: An electromagnet is installed on the vertical rod at the position of the plug-in block. The plug-in block is made of iron. A box body is fixedly arranged on the bottom surface of the cutting plate. A sliding strip is slidably installed in the box body. Detection units are arranged at both ends of the sliding strip. The detection units are connected to the electromagnet.

[0012] As a further scheme of the present invention: A counterweight block is clamped at the bottom end of the vertical rod.

[0013] As a further scheme of the present invention: Wheels are installed at the bottom of the support plate.

[0014] As a further scheme of the present invention: A round shaft is fixedly arranged on the side of the vertical rod away from the second vertical plate. The round shaft passes through the first vertical plate and is rotationally matched with the first vertical plate.

[0015] As a further scheme of the present invention: The center of the arc-shaped groove coincides with the axis of the round shaft.

[0016] A method for ice breaking using the above-mentioned railway tunnel ice breaking device includes the following steps: Push the device into the tunnel so that the cutting knife is located at the top wall of the tunnel, drive the cutting knife to deflect through the vertical rod, and use the swing of the cutting knife to break the icicle; When encountering a large-sized icicle, the vertical rod and the cutting knife stop swinging, and the vibration component can drive the cutting knife to reciprocate, thereby cutting off the large-sized icicle.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: This device can quickly break the icicle at the top wall of the tunnel by driving the vertical rod to swing. When encountering a large-sized icicle that cannot be directly broken by the cutting knife, the vibration component provided can drive the cutting knife to reciprocate, so as to use the cutting knife to clean the large-sized icicle or ice layer. Compared with continuously driving the cutting knife to reciprocate to cut the icicle, this method is more energy-saving, and the overall device is also more lightweight.

Detailed implementation manner

[0020] As Figures 1-17 shown, a railway tunnel ice-breaking device and an ice-breaking method include a support plate 2 and a vertical rod 8 arranged above the support plate 2. The vertical rod 8 can swing left and right relative to the support plate 2 on a vertical plane, and a cutting plate 9 for breaking the ice column on the inner wall of the tunnel 1 is fixedly arranged at the top of the vertical rod 8; In order to drive the vertical rod 8 to swing, in this solution, a second vertical plate 202 is fixedly installed on the top surface of the support plate 2. A rotating rod 6 is rotatably installed on one side of the second vertical plate 202 close to the vertical rod 8, and a U-shaped frame 10 is fixedly arranged at the top of the rotating rod 6. Combining Figure 2 , Figure 6 , Figures 14-15As shown in the figure, pressing strips 1001 are hinged to both the left and right sides of the frame body 10. In the initial state, the pressing strips 1001 can only deflect inward relative to the frame body 10. On the side of the vertical rod 8 close to the frame body 10, a sliding rod 20 is slidably assembled. One end of the sliding rod 20 extending into the frame body 10 is provided with a conical surface 2001. Through the cooperation of the pressing strip 1001 and the sliding rod 20, the vertical rod 8 can be driven to deflect, so as to break the icicle at the inner wall of the tunnel 1. When the volume of the icicle is so large that the cutting plate 9 cannot break it, through the provided conical surface 2001, the pressing strip 1001 can cross over the sliding rod 20.

[0021] In order to clean the icicles with a large volume, in this solution, cutting knives 12 are assembled on both sides of the top of the cutting plate 9, and the cutting knives 12 can move back and forth relative to the cutting plate 9. During actual use, when the cutting knives 12 cannot directly break the icicles with a large volume, the cutting knives 12 can be reciprocated to cut the icicles. To achieve the above effect, a driving frame 7 is fixedly installed on the surface of the frame body 10 away from the vertical rod 8. The driving frame 7 is in a "hui" - shaped structure and sleeved outside the vertical rod 8. Refer to Figures 2-3 As shown in the figure, the whole driving frame 7 is arc - shaped and its center of the circle is on the same straight line as the rotation center of the vertical rod 8; Combined with Figure 5 As shown in the figure, a rotating shaft 18 is slidably assembled on the side of the vertical rod 8 away from the sliding rod 20. A spur gear 1801 is fixedly sleeved on the outside of the rotating shaft 18. On one side of the bottom of the driving frame 7, there are two sets of transmission teeth 701 meshing with the spur gear 1801. The two sets of transmission teeth 701 are distributed on both sides of the spur gear 1801. The rotating shaft 18 is connected to the cutting knife 12 through a vibration assembly. When the rotating shaft 18 is driven to rotate by the meshing of the transmission teeth 701 and the spur gear 1801, the rotating shaft 18 can, through the vibration assembly, prompt the cutting knife 12 to reciprocate in the front - and - back direction, so as to cut the icicles.

[0022] The driving assembly includes a sleeve 14. The sleeve 14 is sleeved outside the rotating shaft 18 and the sliding rod 20, and the rotating shaft 18 can drive the sleeve 14 to rotate synchronously. A plurality of protrusions 1401 are fixedly arranged on the outer peripheral wall of the sleeve 14. A pressing rod 16 is arranged along the length direction of the vertical rod 8, and the pressing rod 16 passes through the vertical rod 8 and is slidably matched with it. One side of the top of the pressing rod 16 is set as an inclined extrusion surface 1601; Refer to Figure 7 As shown in the figure, a roller 17 is arranged at the extrusion surface 1601. Combined with Figures 3-4As shown, the two cutting blades 12 are fixedly connected by a connecting bar 13, and the roller 17 is cooperated with one of the connecting bars 13 through a bracket. Specifically, one end of the bracket is fixedly arranged on the connecting bar 13, and the roller 17 is rotatably installed on the other end of the bracket. The bottom end of the pressure bar 16 extends to the outer peripheral wall of the sleeve 14. With this structure, when the spur gear 1801 drives the sleeve 14 to rotate, the cooperation between the protrusion 1401 and the pressure bar 16 can drive the pressure bar 16 to reciprocate relative to the vertical rod 8, and then drive the cutting blade 12 to reciprocate by the cooperation between the extrusion surface 1601 and the roller 17.

[0023] A boss 19 is integrally formed on one side of the vertical rod 8 close to the frame 10, and the slide rod 20 is elastically connected to the boss 19. The vertical rod 8 is elastically connected with a plug block 22, and the plug block 22 is set to be T-shaped. An annular groove 2003 matching the plug block 22 is formed on the outer peripheral wall of the slide rod 20. When the slide rod 20 is pressed by the pressing strip 1001 and shrinks into the vertical rod 8, the plug block 22 and the annular groove 2003 can cooperate to lock the slide rod 20. Refer to Figure 5 、 Figure 8 As shown, in the initial state, the transmission gear 701 and the spur gear 1801 are in a staggered state. When the slide rod 20 is pressed and drives the rotating shaft 18 to move, the spur gear 1801 can move along with the rotating shaft 18 and be coplanar with the transmission gear 701.

[0024] A first vertical plate 201 is fixedly installed on the top surface of the support plate 2. A round shaft 803 is fixedly arranged on one side of the vertical rod 8 away from the second vertical plate 202. The round shaft 803 passes through the first vertical plate 201 and is rotatably matched with it, so that the vertical rod 8 can deflect around the round shaft 803. An arc-shaped groove is formed on the first vertical plate 201, and the center of the arc-shaped groove coincides with the axis of the round shaft 803. A slider 804 is slidably installed in the arc-shaped groove, and the slider 804 is fixedly connected with the vertical rod 8. A plurality of card slots 2011 are evenly formed on the top wall or bottom wall of the inner cavity of the arc-shaped groove, and two card blocks 23 matching the card slots 2011 are elastically connected to the slider 804. Refer to Figure 10 As shown, inclined surfaces 2301 are arranged on the opposite sides of the two card blocks 23. The cooperation between different card blocks 23 and the card slots 2011 can limit the sliding direction of the slider 804.

[0025] During actual use, the device is moved into Tunnel 1 so that the cutting knife 12 is located at the top wall of Tunnel 1. At this time, the rotating rod 6 is driven to rotate by an external driving component. And in the initial state, one end of the sliding rod 20 is located inside the frame 10. So that as the frame 10 deflects along with the rotating rod 6, the vertical rod 8 can be driven to deflect through the pressing strip 1001. The deflection of the cutting knife 12 can be used to quickly clean some ice columns with smaller sizes. When encountering an ice column with a larger size, the force between the sliding rod 20 and the pressing strip 1001 is not sufficient to break the ice column. As the force between the pressing strip 1001 and the sliding rod 20 gradually increases, the extrusion of the conical surface 2001 on the sliding rod 20 by the pressing strip 1001 can prompt the sliding rod 20 to move relative to the vertical rod 8. When the inserting block 22 is aligned with the annular groove 2003, the bottom end of the inserting block 22 can be inserted into the annular groove 2003, thereby limiting the sliding rod 20. In addition, during the movement of the sliding rod 20, the rotating shaft 18 can be pushed, so that the spur gear 1801 on the rotating shaft 18 and the transmission tooth 701 at the bottom of the driving frame 7 are on the same vertical plane. When the pressing strip 1001 passes over the sliding rod 20, as the frame 10 drives the driving frame 7 to move, the transmission tooth 701 will engage with the spur gear 1801 and drive the spur gear 1801 to rotate. Through the cooperation of one of the clamping blocks 23 and the clamping groove 2011 and the restriction of the larger-sized ice column on the cutting knife 12, the vertical rod 8 can be kept relatively stable, so that the transmission tooth 701 and the spur gear 1801 can be stably matched; During the process of the spur gear 1801 driving the rotating shaft 18 to rotate, the rotating shaft 18 can synchronously drive the sleeve 14 to rotate. By continuously extruding the bottom of the pressing rod 16 through the multiple protrusions 1401 on the outer side of the sleeve 14, the pressing rod 16 can be driven to reciprocate in the vertical direction. And the pressure of the inclined surface 2301 on the pressing rod 16 on the roller 17 can prompt the cutting knife 12 to reciprocate relative to the cutting plate 9, and then the larger-sized ice column can be cut.

[0026] In summary, this device can quickly break the ice column at the top wall of Tunnel 1 by driving the vertical rod 8 to swing. When encountering an ice column with a larger size that makes the cutting knife 12 unable to directly break it, the arranged vibration component can drive the cutting knife 12 to reciprocate, so as to clean the larger-sized ice column or ice layer by using the cutting knife 12. Compared with continuously driving the cutting knife 12 to reciprocate to cut the ice column, this method is more energy-saving, and the whole device is also more portable.

[0027] In order to drive the deflection of the rotating rod 6, a connecting shaft 601 is fixedly arranged on one side surface of the rotating rod 6 close to the second vertical plate 202. The connecting shaft 601 passes through the second vertical plate 202 and is rotatably connected thereto. One end of the connecting shaft 601 passing through the second vertical plate 202 is fixedly provided with a driven gear. The above-mentioned driving assembly includes a sliding plate 4 slidably arranged on the top of the support plate 2. A rack 5 meshing with the driven gear is fixedly arranged on the top surface of the sliding plate 4. Specifically, a slide rail cooperating with the sliding plate 4 can be installed on the support plate 2 to improve the stability of the movement of the sliding plate 4. A motor is installed on the top of the support plate 2. The output shaft of the motor is drivingly connected with a lead screw 3. The lead screw 3 passes through the sliding plate 4 and is in threaded connection therewith. By the forward and reverse rotation of the lead screw 3, the sliding plate 4 and the rack 5 can be driven to reciprocate, and then the rotating rod 6 can be driven to deflect through the cooperation of the rack 5 and the driven gear. In actual use, when the frame 10 is disengaged from the sliding rod 20, the staff can control the motor to cause the frame 10 and the driving frame 7 to reciprocate and deflect, thereby driving the cutting knife 12 to reciprocate.

[0028] An electromagnet 21 is installed on the vertical rod 8 at the position of the insertion block 22, and the insertion block 22 is made of iron. When the electromagnet 21 is powered on, the suction force of the electromagnet 21 on the insertion block 22 can be used to separate the insertion block 22 from the annular groove 2003. Specifically, a box body 11 is fixedly arranged on the bottom surface of the cutting plate 9. The inside of the box body 11 is a cavity structure. A slide bar 1101 is slidably installed in the box body 11, and detection units 1102 are arranged at both ends of the slide bar 1101. The detection units 1102 are fixedly arranged at both ends inside the box body 11. The detection unit 1102 can be a pressure sensor, and the pressure sensor can be electrically connected to the above-mentioned electromagnet 21; In actual use, a counterweight 25 can be clamped at the bottom end of the vertical rod 8. Figure 12The initial position of the vertical rod 8 is shown. At this time, due to the gravity of the counterweight 25, there is a tendency to drive the vertical rod 8 to deflect. Specifically, when the cutter 12 encounters an ice column with a relatively large size within the range of 0 - 90°, according to the description above, the vibration assembly can drive the cutter 12 to reciprocate, thereby cutting the ice column. As the cutter 12 continuously cuts, the counterweight 25 can drive the vertical rod 8 to deflect, so that the cutter 12 can always contact the ice column and cut it. After the cutter 12 cuts off the large-sized ice column, the counterweight 25 can cause the vertical rod 8 to deflect rapidly until it encounters the next ice column. When the cutter 12 collides with the next ice column and stops, due to the effect of inertia, the slide bar 1101 in the box body 11 exerts a large pressure on the pressure sensor at one end, thereby controlling the electromagnet 21 to be in the energized state through the pressure sensor. Using the suction force of the electromagnet 21 on the insertion block 22, one end of the insertion block 22 can be driven to move away from the annular groove 2003, so that the slide rod 20 can pop out and cooperate with the pressure strip 1001 on the frame 10 again; A notch matching the vertical rod 8 is formed on the counterweight 25, and a cross groove is formed at the inner wall of the notch. The cross groove extends to the outer wall of the counterweight 25 at the end far from the vertical rod 8. A plug rod 27 is slidably arranged in the cross groove. Of course, the plug rod 27 is also cross-shaped. Springs are fixedly arranged between the two protruding parts on the upper and lower sides of the plug rod 27 and the end face of the cross groove. A groove matching the plug rod 27 is formed on the side surface of the vertical rod 8. When one end of the plug rod 27 is inserted into the groove, the counterweight 25 is inserted into the vertical rod 8. Of course, a chamfer is arranged at the bottom end face of the vertical rod 8 to facilitate the insertion of the vertical rod 8 into the notch. A magnet 26 is fixedly embedded on the side surface of the first vertical plate 201 close to the vertical rod 8. The above plug rod 27 is made of iron. The counterweight 25 and the first vertical plate 201 are in a fitting state. When the vertical rod 8 rotates to the vertical state, the magnet 26 is aligned with the plug rod 27. The suction force of the magnet 26 on the plug rod 27 can move one end of the plug rod 27 out of the groove, so that the counterweight 25 can be separated from the vertical rod 8. When the cutter 12 continues to deflect from the vertical state, due to the self-weight of the cutting plate 9 and the cutter 12, the vertical rod 8 has a tendency to deflect downward, so that the cutter 12 can stably fit with the large-sized ice column.

[0029] Combined with Figure 1 As shown, wheels are installed at the bottom of the support plate 2 to facilitate driving the whole device to move.

[0030] A through groove is formed on the vertical rod 8, and the sleeve 14 is installed at the through groove. Two screw rods 15 are threadedly connected to the outside of the slider 804. Combined with Figures 10-11As shown, two mounting grooves are formed on the top surface of the slider 804. The two clamping blocks 23 are respectively slidably mounted in the mounting grooves, and a limiting spring is fixedly arranged between the inner end surface of the mounting groove and the clamping block 23. One end of the screw rod 15 and the clamping block 23 are fixedly provided with a pulling rope 24. The pulling rope 24 passes through the slider 804 and is slidably matched with it. Since the inclined surfaces 2301 on the two clamping blocks 23 are arranged oppositely, by rotating the screw rod 15, different clamping blocks 23 can be controlled to cooperate with the clamping grooves 2011. For example, when the vertical rod 8 deflects from left to right, combined with Figure 10 As shown, one of the screw rods 15 can drive the right clamping block 23 to be received into the slider 804. At this time, the vertical rod 8 can only deflect to the right relative to the first vertical plate 201.

[0031] A guiding block 1301 is fixedly arranged on the bottom surface of the connecting strip 13, and a guiding groove slidably matched with the guiding block 1301 is formed on the top surface of the cutting plate 9. A cross bar is fixedly arranged in the guiding groove. The cross bar passes through the guiding block 1301 and is slidably matched with it. A first spring is sleeved outside the cross bar. The first spring is fixedly arranged between the guiding block 1301 and the end surface of the guiding groove.

[0032] A through groove is formed on the vertical rod 8, and a connecting block 1602 slidably matched with the through groove is fixedly mounted on the pressing rod 16. A second spring is fixedly arranged between the connecting block 1602 and the end surface of the through groove, so as to realize the elastic cooperation between the pressing rod 16 and the vertical rod 8.

[0033] A stepped hole with a cross section of "cross" is formed at the boss 19, and the stepped hole is communicated with the above-mentioned through groove. A convex ring 2002 is fixedly sleeved outside the sliding rod 20. The convex ring 2002 slides in the stepped hole, and a compression spring is fixedly arranged between the inner end surface of the stepped hole and the convex ring 2002. This structure is beneficial to drive the sliding rod 20 to reset. A storage groove for installing the electromagnet 21 and the plug-in block 22 is formed on the vertical rod 8. The cross section of the storage groove is T-shaped, and the storage groove is communicated with the above-mentioned stepped hole. Specifically, the electromagnet 21 is fixedly arranged in the storage groove, and a third spring is arranged between the electromagnet 21 and the plug-in block 22. When the electromagnet 21 is powered off, the bottom end of the plug-in block 22 can pass through the storage groove and cooperate with the annular groove 2003 outside the sliding rod 20.

[0034] A limiting groove 1402 is formed on the inner wall of the sleeve 14, and a limiting block 1802 slidably matched with the limiting groove 1402 is fixedly arranged on the outer wall of the rotating shaft 18. The rotating shaft 18 and the sliding rod 20 can be rotatably matched through a tapered roller bearing. Through this structure, the rotating shaft 18 can move relative to the sleeve 14 and can drive the sleeve 14 to rotate synchronously.

[0035] Combined with Figures 14-15As shown, circular rods 28 are fixedly arranged at both the top and bottom ends of the pressing strip 1001, and protrusions 2801 are fixedly arranged on the outer wall of the circular rods 28. Installation holes that are rotationally matched with the circular rods 28 are provided on both the top wall and the bottom wall of the inner part of the frame body 10. The installation holes are stepped. A coil spring 29 is sleeved outside the circular rods 28. Two ends of the coil spring 29 are respectively fixedly connected to the outer wall of the circular rods 28 and the inner wall of the installation holes. A stop block 1002 that is matched with the protrusions 2801 is fixedly arranged on the inner wall of the installation holes. In the initial state, due to the acting force of the coil spring 29, the protrusions 2801 and the stop block 1002 are in a state of being in contact with each other, so that the pressing strip 1001 can only deflect inwards relative to the frame body 10. With this structure, after the sliding rod 20 pops out again, the frame body 10 can move to the position of the sliding rod 20 again, so that the end of the sliding rod 20 is again inside the frame body 10.

[0036] Combined with Figure 17 As shown, during actual use, the vertical rod 8 can be set to a telescopic structure. Specifically, the vertical rod 8 can be divided into upper and lower parts.
