However, due to the dissolution (calcification) produced by wall leakage, coal powder falling, and powder produced by vibration and friction of the roadbed, the drainage ditch is silted and drainage is not smooth. Taking the Shuohuang Line as an example, the line has a long span, tall mountains, large water storage capacity, and long drainage ditches. It has the typical characteristics of a long tunnel of a heavy-duty railway in a mountainous area, which has always been the focus, difficulty, and weakness of the Shuohuang Line. In recent years, the density of 20,000-ton heavy-duty trains has continued to increase. Affected by factors such as the scattering of coal ash dust, grouting for comprehensive tunnel renovation, and friction and vibration of the roadbed, the silt deposition in the tunnel drainage ditch has increased year by year, resulting in poor drainage of the tunnel, which in turn causes mud and water to flood the roadbed, causing roadbed slurry and mud to occur, affecting driving safety.

DETAILED DESCRIPTION

[0054] In order to make the technical solutions and advantages of the embodiments of the present application more clear, the following Figure 1-7 The exemplary embodiments of the present application are further described in detail. Obviously, the described embodiments are only part of the embodiments of the present application, rather than an exhaustive list of all the embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0055] In the process of realizing the present application, the inventor found that due to the influence of seasonal changes, karst water, groundwater, rainwater, etc., the tunnel is equipped with drainage ditches and drainage wells to prevent water damage. However, due to the influence of the dissolution (calcification) produced by the wall leakage, the falling of coal powder and the powder produced by the vibration and friction of the roadbed, the drainage ditch is silted and the drainage is not smooth. Taking the Shuohuang Line as an example, the line has a long span, tall mountains, large water storage capacity, and long drainage ditches. It has the typical characteristics of a long tunnel of a heavy-duty railway in a mountainous area, which has always been the maintenance focus, difficulty and weakness of the Shuohuang Line. In recent years, the running density of 20,000-ton heavy-duty trains has continued to increase. Affected by factors such as the scattering of coal ash dust, grouting for comprehensive tunnel renovation, and friction and vibration of the roadbed, the silt deposition in the tunnel drainage ditch has increased year by year, resulting in poor drainage of the tunnel, which in turn causes the muddy water to flood the roadbed, causing the roadbed to turn over and mud, and other diseases, affecting driving safety.

[0056] At present, the dredging work of the Baoshen Railway is mainly done manually, but there are the following problems with manual cleaning and maintenance: (1) The manual cleaning work is very intensive; (2) The silt in the underground pipes of the drainage ditch cannot be cleaned; (3) The total number of kilometers to be cleaned is long, the manual cleaning efficiency is low, and the operation cycle is long.

[0057] Therefore, in order to solve the problems of high labor intensity, poor working environment, low working efficiency, inability to clean the silt in the underground pipe of the drainage ditch, and long silt removal time during the dredging of railway tunnel drainage ditches, key technologies for mechanized dredging of tunnel drainage ditches are studied, including vacuum suction, high-pressure dredging and cleaning, sewage recycling, automatic unloading, etc. Therefore, a railway tunnel drainage ditch dredging vehicle with independent intellectual property rights is developed, which integrates flushing, dredging, sewage suction, sewage separation and recycling treatment, immediate reuse, loading and unloading, etc., to meet the needs of mechanized dredging, silt cleaning, collection and off-site unloading of drainage ditches, dense wells, precipitation wells and other railway tunnel drainage facilities.

[0058] In order to solve the above problems, a mechanical boom device for a railway silt clearing vehicle and a railway silt clearing vehicle are provided in an embodiment of the present application.

[0059] According to a first aspect of an embodiment of the present application, a mechanical boom device for a railway silt removal vehicle (hereinafter referred to as the mechanical boom device) is provided, such as Figure 1-7 As shown, including:

[0060] The horizontally arranged mechanical arm frame 101 comprises two arms parallel to each other. The mechanical arm frame 101 is rotatably arranged on the railway silt removal vehicle. The mechanical arm frame 101 can be rotated by a mechanical arm frame driving device;

[0061] The sewage suction pipe reel 102 is horizontally arranged and rotatably arranged on the mechanical arm frame 101. The sewage suction pipe reel 102 can rotate in a horizontal plane through a sewage suction pipe reel driving device;

[0062] The sewage suction pipe 103 is slidably arranged on the arm on the left side of the mechanical arm frame 101. The sewage discharge end of the sewage suction pipe 103 is connected to the sewage suction pipe reel 102. The sewage suction pipe reel 102 can coil and retract the sewage suction pipe 103 by self-rotation.

[0063] The telescopic mechanism 105 is slidably connected to the arm on the left side of the mechanical arm frame 101, and can extend or shorten the path of the sewage suction pipe 103 on the arm. The telescopic mechanism can be pushed out and retracted along the arm direction by a pneumatic or hydraulic cylinder;

[0064] The guide mechanism is connected to the free end of the telescopic mechanism 105 and can guide the sewage suction pipe 103 downward into the working point.

[0065] During specific implementation, the mechanical arm frame 101 is rotated by the mechanical arm frame driving device to rotate the entire mechanical boom device to the designated operating point, and the travel of the telescopic mechanism is adjusted by the pneumatic or hydraulic cylinder so that the common length of the telescopic mechanism 105 and the arm matches the length of the sewage suction pipe 103. The guide mechanism is located above the operating point, and the sewage suction pipe reel driving device is started to release the sewage suction pipe 103 by rotating the sewage suction pipe reel 102. At the same time, the guide mechanism is started to guide and assist in the release of the sewage suction pipe 103. The sewage suction pipe 103 starts from the sewage suction pipe reel 102, passes through the arm and the telescopic mechanism 105 on the left side of the mechanical arm frame 101 in turn, and then extends downward through the guide mechanism to enter the operating point; after the dredging operation is completed, the sewage suction pipe reel driving device drives the sewage suction pipe reel 102 to rotate in the opposite direction, and rewinds the sewage suction pipe 103 back onto the sewage suction pipe reel 102.

[0066] As a preferred solution, the guiding mechanism includes:

[0067] The auxiliary roller 106 and the retractable driving wheel 107 are respectively connected to the free ends of the telescopic mechanism 105 through roller guide frames. The auxiliary roller 106 is located above the retractable driving wheel 107. A downward inclined passage is formed between the auxiliary roller 106 and the retractable driving wheel 107. The sewage suction pipe 103 extends along the downward inclined passage to enter the working point. A driving motor is arranged on the roller guide frame of the retractable driving wheel 107, and the output shaft of the driving motor is connected to the retractable driving wheel 107.

[0068] During specific implementation, in the above-mentioned dredging operation, when the guide mechanism is assisting in the release, the drive motor is started, the retractable driving wheel 107 rotates, and cooperates with the auxiliary roller 106 to jointly assist in the release of the suction pipe 103 by the rotating turntable 102. At the same time, the auxiliary roller 106 and the retractable driving wheel 107 can guide the suction pipe 103 so that it can be accurately extended to the operation point; when the guide mechanism is recovering the suction pipe 103, the drive motor is started, the retractable driving wheel 107 rotates in the opposite direction, and cooperates with the auxiliary roller 106 to jointly assist in the recovery of the suction pipe 103 by the rotating turntable 102.

[0069] As a preferred solution, Figure 2 As shown, the sewage suction end of the sewage suction pipe 103 is connected to a sewage suction pipe port assembly 200, and the sewage suction pipe port assembly 200 includes:

[0070] Connect the hard pipe seat 201 and sleeve it inside the sewage suction pipe 103;

[0071] The connection fixing card 202 is sleeved on the sewage suction pipe 103. After the connection fixing card 202 is tightened and locked, the sleeved connection hard pipe seat 201 and the sewage suction pipe 103 can be fastened;

[0072] The connecting hard pipe 203 is connected to the connecting hard pipe seat 201 through a flange;

[0073] The dirt suction filter 204 is detachably disposed at the end of the connecting hard pipe 203 .

[0074] Specifically, the end of the connecting hard pipe 203 can be replaced with a suction filter of different apertures according to the conditions of the desilting location, such as Figure 2 As shown, the sewage suction filter net 1 204 can be replaced with the sewage suction filter net 205 or the sewage suction filter net 3 206.

[0075] During the specific implementation, before the dredging operation, the sludge at the operation point can be sampled and tested to determine the appropriate suction filter. If blockage occurs during the dredging operation, the machine should be stopped in time and the filter should be replaced to avoid malfunction of the dredging vehicle.

[0076] As a preferred solution, a flushing water pipe reel 108 is provided on the arm on the right side of the robotic arm frame 101. The flushing water pipe reel 108 can coil and retract the water pipe. The input end of the water pipe of the pipeline support 104 is connected to a high-pressure water pump. The flushing water pipe reel 108 can be rotated by a flushing water pipe reel driving device, thereby coiling and retracting the water pipe.

[0077] During specific implementation, when encountering a sludge operation point with low water content, or encountering stubborn sludge that is difficult to suck in, start the flushing mechanism drive device, flush the water pipe reel 108 to release the water pipe by rotation, turn on the high-pressure water pump, and use the sprayed high-pressure water flow to flush and clean the operation point, and cooperate with the sewage suction pipe 103 to suck the sewage.

[0078] As a preferred solution, the mechanical boom device further includes a pipeline bracket 104 , which is disposed on the mechanical arm frame 101 , and the control harness and pipelines can be arranged through the pipeline bracket 104 .

[0079] According to a second aspect of an embodiment of the present application, a railway silt removal vehicle is provided, comprising:

[0080] Any of the above mechanical boom devices;

[0081] Install the frame 701;

[0082] A sewage storage tank 703 is mounted on a mounting frame 701;

[0083] Two vertical side brackets 705 are respectively installed on the mounting frame 701 and located on both sides of the sewage storage tank 703. A ladder is installed on the side bracket 705 to facilitate management and maintenance by the staff;

[0084] A support bracket 702 is disposed above the sewage storage tank 703, and the support bracket 702 is connected to the tops of the two side brackets 705;

[0085] The boom connection assembly 500 , the mechanical arm frame 101 is rotatably connected to the support bracket 702 via the boom connection assembly 500 .

[0086] In specific implementation, the support bracket 702 and the side brackets 705 on both sides jointly support and protect the sewage storage tank 703 and the mechanical boom device to ensure the safety of the railway silt removal vehicle. From the perspective of space utilization, equipment maintenance, and safety, the mechanical boom device should be kept in the retracted state during the period of stopping work (standby) and during the transportation of the railway silt removal vehicle, that is, the mechanical boom device should be completely rotated to the top of the railway silt removal vehicle to prevent the mechanical boom device from rotating outward.

[0087] Take the car collection state as the initial state, such as Figure 7 As shown, the mechanical arm device is rotated by the mechanical arm frame driving device, and rotates from the vehicle collection position 801 by θ1 to the rotation position one 802, and can also rotate from the vehicle collection position 801 by θ2 to the rotation position two 803, and rotates back along the rotation path when retracting;

[0088] The mechanical boom device is extended from the boom retracted position L1 to the boom extended position L2 through the telescopic mechanism 105, and retracts along the extended path when retracting;

[0089] The mechanical boom device drives the water pipe to extend and retract by rotating the flushing water pipe reel 108 at an angle of θ3;

[0090] The mechanical boom device drives the suction pipe 103 to extend and retract by rotating the suction pipe reel 102 at an angle of θ4. During this process, the auxiliary roller 106 and the retracting driving wheel 107 cooperate with the auxiliary suction pipe 103 to complete the extension or retraction process.

[0091] As a preferred solution, Figure 3 As shown, the boom connection assembly 500 includes:

[0092] The boom base flange 501 and the support bracket 702 are provided with a vehicle frame pre-installed flange 704, and the boom base flange 501 is connected to the vehicle frame pre-installed flange 704 through the boom base connecting bolts 503;

[0093] A hollow pipe is provided in the middle of the sewage suction pipe base 502, the boom base flange 501 and the frame pre-installed flange 704, the hollow pipe is connected to the sewage storage tank 703, the sewage suction pipe base 502 is connected to the top of the hollow pipe by rotation and sealing, and the sewage suction pipe base 502 is fixedly connected to the support bracket 702;

[0094] A suction pipe joint is installed in the middle of the suction pipe reel 102 , one end of which is connected to the sewage discharge end of the suction pipe 103 , and the other end of which is downwardly connected to the top rotation seal of the suction pipe base 502 .

[0095] In the process of implementing the present application, the inventors found that, in the standby state, it is relatively easy to maintain the mechanical boom device in the above-mentioned vehicle receiving position 801. However, during transportation, due to the bumpy road surface, the mechanical boom device is not easy to maintain in the above-mentioned vehicle receiving position 801. Therefore, it is necessary to install a locking mechanism to limit the mechanical boom device under the vehicle receiving position 801.

[0096] In view of the above problems, a preferred solution is provided in the embodiments of the present application. Figure 4 As shown, a locking device 400 is installed on the support bracket 702, and the locking device 400 includes:

[0097] The lock fixing seat 402 is arranged on the support bracket 702, and the lock tongue 403 of the lock fixing seat 402 is arranged upward. The installation position of the lock fixing seat 402 is such that in the folded state, the lock tongue 403 can block the mechanical arm frame 101 from rotating outward after being extended, and the lock tongue 403 does not affect the mechanical arm frame 101 from rotating outward after being retracted;

[0098] A controller 401 capable of controlling the lock tongue 403 to extend or retract;

[0099] The position sensor 404 can monitor the position information of the locking tongue 403 .

[0100] In specific implementation, two locking devices 400 can be symmetrically installed on the support bracket 702 to limit the rotation of the robotic arm frame 101 to both sides. After entering the vehicle retracting state, the lock tongue 403 is extended through the controller, and the position sensor can be used to confirm whether the lock tongue 403 is extended / retracted. The position information of the lock tongue 403 needs to be confirmed before driving the robotic arm frame 101 to rotate.

[0101] In the process of realizing the present application, the inventors found that during transportation, the end of the sewage suction pipe 103 would swing irregularly with the bumps of the vehicle, which would not only affect driving safety but also easily scratch the pipe.

[0102] In view of the above problems, a preferred solution is provided in the embodiments of the present application. Figure 5 As shown, a sewage suction pipe protection frame assembly 300 is installed on the mounting frame 701. The sewage suction pipe protection frame assembly 300 is arranged in the vehicle folding state, directly below the sewage suction pipe 103 that naturally droops. The sewage suction pipe protection frame assembly 300 includes:

[0103] The protective support 301 is vertically mounted on the mounting frame 701;

[0104] The fixed lock 303 includes a lock body and a lock buckle. The lock body is arranged on the protective support 301. The lock body is recessed with a semicircular arc groove. The lock buckle is a semicircular ring. One end of the lock buckle is hinged to the lock body.

[0105] The rotating cover plate 302 is arranged on the lock body, and locking is completed by rotating the cover plate 302 after the lock buckle and the lock body are closed.

[0106] In specific implementation, before transportation, open the rotating cover 302, rotate the lock to fully open, put the suction pipe 103 into the lock body, close the lock, and lock the rotating cover 302 to complete the fixation of the suction pipe 103 in the storage state. After arriving near the operation point, unlock the suction pipe protection frame assembly 300 again to release the suction pipe 302. In the process of realizing this application, the inventor found that since the mechanical boom device can be locked in the storage state, then during dredging, in order to further stabilize the suction pipe, a limit assembly can also be installed at a certain position in the working state.

[0107] In view of the above-mentioned problem, a preferred solution is provided in the embodiment of the present application. In the present embodiment, only the example of limiting the mechanical boom device to the second rotation position 803 is used for explanation. It must be noted that it does not mean that the limit assembly can only be installed here.

[0108] like Figure 1 and Figure 6 As shown, a limit assembly 600 is installed on the support bracket 702, and the limit assembly 600 includes:

[0109] The position limiting mounting seat 602 is arranged on the supporting bracket 702, and a plug hole in the vertical direction is arranged on the position limiting mounting seat 602, and a plurality of connecting bolts 603 are screwed on the position limiting mounting seat 602 perpendicularly to the plug hole;

[0110] The limiting installation pin 601 is inserted into the insertion hole, and then the limiting installation pin 601 is limited by tightening the connecting bolt 603.

[0111] In specific implementation, the limiting assembly 600 is used together with the blocking block 109, which is arranged on the support bracket 702. The installation position of the blocking block 109 is based on the fact that when the mechanical arm device is located at the second rotation position 803, the blocking block 109 can block the mechanical arm frame 101 from rotating outward from the outside of the mechanical arm frame 101; the installation position of the limiting mounting seat 602 and the final height of the limiting mounting pin 601 are based on the fact that when the mechanical arm device is located at the second rotation position 803, the limiting mounting pin 601 is inserted into the socket and tightened, and the limiting mounting pin 601 can block the mechanical arm frame 101 from rotating inward from the inside of the mechanical arm frame 101. The blocking block 109 and the limiting assembly 600 respectively complete the limiting of the inner and outer sides of the mechanical arm frame 101, and limit the mechanical arm device at the second rotation position 803.
