Description

Technical Field

[0001] The invention relates to the technical field of hydraulic tunnel transportation, and in particular to a hydraulic tunnel transportation system. Background Art

[0002] Rail trolleys are widely used in horizontal transportation of tunnel pressure steel pipes, tunnel pressure steel pipe welding construction, tunnel drilling and grouting construction, tunnel formwork binding construction and formwork support construction, especially in the installation of pressure steel pipes and tunnel grouting construction of water conservancy and hydropower projects.

[0003] Generally, circular tracks are installed in tunnels, so that the track trolley does not need to return to the original route after transportation is completed. However, in order to shorten the construction period, sometimes it is necessary to carry out construction at different workstations in a tunnel. When transportation is required in the deep tunnel, the way may be blocked by the workstation located in the shallow position. At this time, either the track trolley can only wait for the unloading of the material to be completed and then transport it above, or the track trolley can be temporarily moved off the track. However, at workstations such as tunnel drilling and grouting construction, the unloading is slow and it is inconvenient to move away from the track trolley, so it can only be transported after it is completed, which delays the construction period. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention proposes a hydraulic tunnel transportation system, comprising a circular track, on which a plurality of track trolleys are movably arranged; the circular track comprises an entry line and an exit line, and a plurality of track change rails are arranged between the entry line and the exit line; a plurality of first notches are arranged on one side of the entry line and the exit line close to the track change rail, and the first notch of the entry line corresponds to the first notch of the exit line one by one, and the two ends of the track change rail are respectively connected with the first notch of the entry line and the first notch of the exit line, and the two ends of the track change rail are both in arc shape;

[0005] Wherein, a second notch is provided on the side of the entry line and the exit line away from the lane-changing track, and the second notch corresponds to the first notch one by one; a direction-changing structure is provided on the side of the entry line and the exit line away from the lane-changing track and at the position corresponding to each second notch; the direction-changing structure includes a base, on which a horizontal telescopic structure is installed, the telescopic portion of the horizontal telescopic structure extends toward the direction of the lane-changing track, and a connecting plate is installed on the top surface of the telescopic portion, one end of the connecting plate extends to the outer edge of the telescopic portion and a first baffle and a second baffle are installed alternately downward, the lengths of the first baffle and the second baffle correspond to the lengths of the first notch and the second notch, and the first baffle is closer to the lane-changing track than the second baffle; wherein the second baffle is in the shape of an elongated strip, the first baffle is in the shape of a plane on the side close to the second baffle, the first baffle is in the shape of an arc on the side close to the lane-changing track, and the curvature of the arc side of the first baffle is the same as the curvature of the circular arc end of the lane-changing track.

[0006] As an optimization, the distance between the first baffle and the second baffle is equal to the width of the annular track, and the maximum distance between the plane side of the first baffle and the arc side of the first baffle is smaller than the width of the track change rail.

[0007] As an optimization, the arc side of the first baffle, the plane side of the first baffle and the side of the second baffle close to the first baffle are all recessed with rolling grooves, and both ends of the rolling grooves can be connected to the sliding grooves on the track change rail or the circular rail.

[0008] As an optimization, an installation groove is provided on the inner wall at one end of the second notch of the annular track, a spring and a lock column connected to the spring are arranged in the installation groove, and a downward extending lock rod is arranged at the end of the lock column away from the spring; a lock groove structure is provided at the end of the first baffle plate and the end of the second baffle plate, and the lock groove structure is opened upward so that the lock rod can be inserted into the lock groove structure.

[0009] As an optimization, the locking groove structure includes an entrance groove, a transition groove and a locking groove; the entrance groove is extended along the thickness direction of the annular track, and one end of the entrance groove passes through the first baffle or the second baffle, and the other end of the entrance groove is connected to the transition groove, and the end of the transition groove is connected to the end of the locking groove close to the installation groove, and the extension direction of the transition groove from the entrance groove to the locking groove is an inclined structure with a trend of gradually approaching the installation groove, and the locking groove is extended along the length direction of the annular track.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. The present application provides a track change rail between the entry and exit lines of each workstation in the tunnel, and the track change rail is connected to the circular track to realize the rapid transfer of the rail trolley between the entry and exit lines, and the transportation organization is flexible; thereby, the rail trolley at a workstation under construction no longer blocks the operation of the rail trolley used by a workstation located deep inside on the circular track, and the rail trolley that has completed the construction can also be docked in the track change rail, thereby ensuring that when the workstation needs a rail trolley to transport out of the tunnel, there will always be a rail trolley as a spare vehicle.

[0012] 2. The arc connection between the circular track and the first gap of the change track realizes the smooth transition of the rail trolley. The gap generated by the rail trolley during the change of direction is very short, and this process is a gradual process, not a sudden change, which effectively prevents the occurrence of impact; in addition, even when the gap is the largest, the guide wheel will still be stuck in the slide groove, and the rail trolley will not derail.

[0013] 3. The present application provides a direction-changing structure on the side of the circular track away from the track-changing rail and corresponding to each second gap, and controls the plane side of the first baffle or the second baffle to fill the second gap through the horizontal telescopic structure; when the plane side of the first baffle fills the second gap, the two ends of the arc side of the first baffle are respectively connected to the first gap and the second gap, so that the circular track and the track-changing rail are connected, and the effect of transferring the rail trolley between the entry line and the exit line is achieved; when the second baffle fills the second gap, the first gap is filled by the first baffle, and the track-changing rail and the circular track are no longer connected.

[0014] 4. The present application provides an installation groove on the inner wall at one end of the second notch, in which a spring, a lock column and a lock rod are arranged, and a lock groove structure is provided at the end of the first baffle plate and the end of the second baffle plate, so that when the first baffle plate or the second baffle plate is pushed into the second notch, the lock rod also enters the lock groove structure and is finally fixed in the locking groove, and under the action of the spring, the lock rod is always located at the end of the locking groove away from the installation groove, and will not return from the transition groove and the entrance groove; when it is necessary to change the connectivity between the change track and the circular track, it is only necessary to bend the lock column upward to let the lock rod leave the lock groove structure.

[0025] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0026] Example: Figure 1-Figure 9 As shown, a hydraulic tunnel transportation system includes a circular track 1, on which a plurality of track trolleys (not shown) are movably arranged; the circular track 1 includes an entry line 11 and an exit line 12, and a plurality of track change rails 2 are arranged between the entry line 11 and the exit line 12. A plurality of first notches 13 are arranged on the side of the entry line 11 and the exit line 12 close to the track change rail 2, and the first notches 13 of the entry line 11 correspond to the first notches 13 of the exit line 12 one by one, and the two ends of the track change rail 2 are connected to the first notches 13 of the entry line 11 and the first notches 13 of the exit line 12, respectively, and the two ends of the track change rail 2 are both in arc shape.

[0027] In the present application, a changing track is provided between the entry line and the exit line of each workstation in the tunnel, and the changing track is connected to the circular track, so as to realize the rapid transfer of the rail trolley between the entry line and the exit line, and the transportation organization is flexible; thereby, the rail trolley at a workstation under construction no longer blocks the operation of the rail trolley used by a workstation located deep inside on the circular track, and the rail trolley that has completed the construction can also be docked in the changing track, thereby ensuring that when the workstation needs a rail trolley to transport out of the tunnel, there will always be a rail trolley as a spare vehicle.

[0028] Specifically, the second notch 14 is provided on the side of the entry line 11 and the exit line 12 away from the lane-changing track 2, and the second notch 14 corresponds to the first notch 13. A direction-changing structure 3 is provided on the side of the entry line 11 and the exit line 12 away from the lane-changing track 2 and at the position corresponding to each second notch 14; the direction-changing structure 3 includes a base 31, on which a horizontal telescopic structure 32 is installed, the telescopic portion of the horizontal telescopic structure 32 extends toward the lane-changing track 2, and a connecting plate 33 is installed on the top surface of the telescopic portion, one end of the connecting plate 33 extends to the outer edge of the telescopic portion and is installed with alternate first baffles 34 and second baffles 35 downward, the lengths of the first baffles 34 and the second baffles 35 correspond to the lengths of the first notch and the second notch, and the first baffle 34 is closer to the lane-changing track 2 than the second baffle 35. Among them, the second baffle 35 is in the shape of an elongated strip, the first baffle 34 is in the shape of a plane on the side close to the second baffle 35, the first baffle 34 is in the shape of an arc on the side close to the lane-changing rail 2, and the curvature of the arc side of the first baffle 34 is the same as the curvature of the arc end of the lane-changing rail 2.

[0029] During implementation, the horizontal telescopic structure 32 may use a hydraulic cylinder to achieve the horizontal telescopic function, but is not limited thereto and may be adjusted according to actual conditions.

[0030] Specifically, the distance between the first baffle 34 and the second baffle 35 is equal to the width of the annular track 1 , and the maximum distance between the plane side of the first baffle 34 and the arc side of the first baffle 35 is smaller than the width of the lane-changing rail 2 .

[0031] In the present application, when the first baffle 34 fills the first gap 13 and the second baffle 35 fills the second gap 14, the first baffle 34 will be at the junction of the change track 2 and the circular track 1, and will not occupy the track of the circular track 1, thereby not affecting the transportation of the rail trolleys transported to other workstations, and making the connection relationship between the circular track 1 and each change track 2 independent, so that the rail trolleys transported to different workstations do not affect each other.

[0032] Specifically, the arc side of the first baffle plate 34 , the plane side of the first baffle plate 34 and the second baffle plate 35 on its side close to the first baffle plate 34 are all recessed with rolling grooves 7 , and both ends of the rolling grooves 7 can be connected to the slide grooves 4 on the change track 2 or the circular track 1 .

[0033] Specifically, an installation groove 15 is provided on the inner wall at one end of the second notch 14 of the annular track 1, and a spring 16 and a lock column 17 connected to the spring 16 are arranged in the installation groove 15, and a downwardly extending lock rod 18 is provided at the end of the lock column 17 away from the spring 16; the end of the first baffle 34 and the end of the second baffle 35 are both provided with a lock groove structure 8, and the lock groove structure 8 is opened upward so that the lock rod 18 can be inserted into the lock groove structure 8.

[0034] During implementation, the lower end of the locking rod 18 is hemispherical, which makes it easier for the locking rod 18 to roll in the locking slot structure 8 .

[0035] Specifically, the locking groove structure 8 includes an entrance groove 81, a transition groove 82 and a locking groove 83; the entrance groove 81 is extended along the thickness direction of the change track 4, and one end of the entrance groove 81 passes through the first baffle 34 or the second baffle 35, and the other end of the entrance groove 81 is connected to the transition groove 82, and the end of the transition groove 82 is connected to the end of the locking groove 83 close to the mounting groove 15, and the extension direction of the transition groove 82 from the entrance groove 81 to the locking groove 83 is inclined in a trend of gradually approaching the mounting groove 15, and the locking groove 83 is extended along the length direction of the annular track 1.

[0036] In the present application, when the first baffle plate 34 or the second baffle plate 35 is pushed into the second notch 14, the locking rod 18 first enters the entrance groove 81 and then enters the transition groove 82. When in the transition groove 82, the spring 16 is compressed, and when entering the locking groove 83, the restoring force of the spring 16 will make the locking rod 18 always located at the end of the locking groove away from the mounting groove 15, thereby achieving the effect of being fixed in the locking groove 83 without returning to the transition groove 82 and the entrance groove 81; when it is necessary to change the connection state between the change track 2 and the circular track 1, it is only necessary to bend the lock column 17 upward to allow the locking rod 18 to leave the lock groove structure 8.
