Description

Technical Field

[0002] Affected by seasonal fluctuations, karst water, groundwater, and rainwater, tunnels are equipped with drainage ditches and wells to prevent water damage. However, due to the influence of dissolved matter (calcification) from wall leakage, falling coal dust, and powder generated by vibration and friction of the roadbed, the drainage ditches have accumulated silt, resulting in poor drainage. Taking the Shuohuang Line as an example, the line has a long span, tall mountains, large water storage capacity, and long drainage ditches, which are typical characteristics of long tunnels for heavy-duty railways in mountainous areas. These have always been the focus, difficulty, and weakness of the Shuohuang Line's maintenance. In recent years, the frequency of 20,000-ton heavy-duty trains has continued to increase. Due to factors such as the scattering of coal ash dust, comprehensive tunnel renovation grouting, and friction and vibration of the roadbed, the silt deposition in the tunnel drainage ditches has increased year by year, resulting in poor tunnel drainage. This in turn causes mud and water to flood the roadbed, causing roadbed slurrying and mud problems, affecting driving safety.

[0003] At present, the dredging work of the Baoshen Railway is mainly completed manually, but there are the following problems with manual cleaning and maintenance: (1) the intensity of manual cleaning work is high; (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 efficiency of manual cleaning is low, and the operation cycle is long.

[0004] Therefore, to address the problems of high labor intensity, poor working environment, low work efficiency, inability to clean silt in the hidden pipes of drains, and long desilting times during railway tunnel drainage ditch desilting and dredging, key technologies for mechanized tunnel drainage ditch desilting and dredging are being studied, including vacuum suction, high-pressure dredging and cleaning, sewage recycling and reuse, and automatic unloading. Consequently, a railway tunnel drainage ditch desilting and dredging vehicle with independent intellectual property rights has been developed. This vehicle integrates flushing, dredging, sewage suction, sewage separation and recycling for immediate reuse, and loading and unloading functions to meet the needs of mechanized dredging, silt cleaning, collection, and off-site unloading of railway tunnel drainage facilities such as drain ditches, dense wells, and precipitation wells.

Taking the Shuozhou-Huanghuagang line as an example, the line has a long span, high mountains, large water storage, and long drainage ditches, which have the typical characteristics of heavy-load railway long tunnels in mountainous areas, and have always been the maintenance focus, difficulty, and weakness of the Shuozhou-Huanghuagang line. In recent years, the density of 20,000-ton heavy-load trains has been increasing, and due to the influence of coal dust scattering, tunnel comprehensive treatment grouting, track bed friction vibration, and other factors, the silt deposition in the tunnel drainage ditches has been increasing year by year, causing poor tunnel drainage, and further causing the track bed to be submerged in mud, causing diseases such as track bed mud and slurry, and affecting train safety.

[0056] At present, the dredging operation of Baoshen railway is mainly completed by manual work, but manual cleaning and maintenance has the following problems: (1) high labor intensity of manual cleaning operation; (2) the silt in the drainage ditch pipe cannot be cleaned; (3) the total length of the cleaning required is long, the manual cleaning efficiency is low, and the operation period is long.

[0057] Therefore, in order to solve the problems of high labor intensity, poor labor environment, low operation efficiency, the silt in the drainage ditch pipe cannot be cleaned, and long dredging time in the process of dredging and dredging of the railway tunnel drainage ditch, the key technologies of mechanical dredging and dredging of the tunnel drainage ditch are studied, including vacuum suction, high pressure dredging and cleaning, sewage recycling, automatic unloading and the like. Therefore, a railway tunnel drainage ditch dredging and 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 and the like, and meets the needs of mechanical dredging, silt cleaning, collection and off-site unloading of railway tunnel drainage facilities such as drainage ditch, dense well and dewatering well.

[0058] In view of the above problems, a mechanical arm device for a railway dredging vehicle and a railway dredging vehicle are provided in the embodiments of the present application.

[0064] The guide mechanism is connected with the free end of the telescopic mechanism 105, which can guide the suction pipe 103 downward into the working point.

After the dredging work is completed, the suction pipe reel driving device drives the suction pipe reel 102 to rotate reversely, and the suction pipe 103 is rewound on the suction pipe reel 102.

[0069] As a preferred scheme, as shown in Figure 2 The suction pipe 103 is connected with a suction pipe opening assembly 200, the suction pipe opening assembly 200 comprises:

[0070] A connecting hard pipe seat 201 is sleeved in the suction pipe 103;

[0073] The suction filter screen 204 is detachably arranged 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 screen with a different aperture according to the situation of the dredging site. Figure 2 As shown, the suction filter screen 204 can be replaced with a suction filter screen 205 or a suction filter screen 206.

[0075] In specific implementation, before the dredging operation, the sludge at the operation site can be sampled and detected to determine the appropriate suction filter screen. If the blockage occurs during the dredging operation, the filter screen should be replaced in time to avoid the failure of the dredging vehicle.

[0078] As a preferred solution, the mechanical lifting arm device further includes a pipe support 104 arranged on the mechanical arm frame 101, which can arrange and control the wire harness and pipe through the pipe support 104.

[0079] According to a second aspect of the embodiments of the present application, a railway dredging vehicle is provided, which includes:

[0080] Any one of the above mechanical lifting arm devices;

[0081] The mounting frame 701;

[0082] The sludge storage tank 703 is mounted on the mounting frame 701;

[0083] The two vertical side supports 705 are respectively mounted on the mounting frame 701 on the two sides of the sludge storage tank 703. The side supports 705 are provided with a crawling ladder for facilitating the management and maintenance of the staff.

[0084] The support bracket 702 is arranged above the sludge storage tank 703. The support bracket 702 is connected to the top of the two side supports 705.

[0085] The boom connecting assembly 500 is used to rotatably connect the mechanical arm frame 101 and the support bracket 702.

[0086] In particular implementation, the support bracket 702 and the side supports 705 on both sides are used to support and protect the sewage storage tank 703 and the mechanical boom device, thereby ensuring the safety of the railway dredging vehicle. From the perspective of space utilization, equipment maintenance and safety, the mechanical boom device should be kept in the parking state during the stop working (standby) period and the transportation process of the railway dredging vehicle, that is, the mechanical boom device should be rotated to the upper side of the railway dredging vehicle, so as to avoid the mechanical boom device being rotated outward.

[0087] The parking state is taken as the initial state, as shown in FIG. 8, the mechanical boom device is rotated by the mechanical arm frame driving device from the parking position 801 to the rotating position one 802 by an angle of θ1, or from the parking position 801 to the rotating position two 803 by an angle of θ2, and is rotated back along the rotating path during the parking process; Figure 7

[0088] The mechanical boom device is extended by the telescopic mechanism 105 from the boom retracted position L1 to the boom extended position L2, and is retracted along the extending path during the parking process;

[0089] The mechanical boom device is rotated by the flushing water pipe reel 108 by an angle of θ3 to drive the water pipe to extend and retract;

[0090] The mechanical boom device is rotated by the sewage suction pipe reel 102 by an angle of θ4 to drive the sewage suction pipe 103 to extend and retract, and the auxiliary rollers 106 and the parking driving wheels 107 cooperate to assist the sewage suction pipe 103 to complete the extending or retracting process.

[0091] As a preferred solution, as shown in FIG. 5, the boom connecting assembly 500 comprises: Figure 3 The boom base flange 501 is provided with the vehicle frame preset flange 704 on the support bracket 702, and the boom base flange 501 is connected with the vehicle frame preset flange 704 through the boom base connecting bolt 503;

[0092] The sewage suction pipe base 502 is connected with the top of the hollow pipe of the vehicle frame preset flange 704 in a rotatable sealing manner, and is fixedly connected with the support bracket 702;

[0093]

[0094] ​​The middle part of the sewage suction pipe reel 102 is provided with a sewage suction pipe joint, one end of the sewage suction pipe joint is connected with the sewage discharge end of the sewage suction pipe 103, and the other end of the sewage suction pipe joint is connected with the top rotating seal of the sewage suction pipe base 502.

[0095] In the process of implementing the present application, the inventor found that it is relatively easy to maintain the mechanical arm device in the above-mentioned parking position 801 in the standby state, but during transportation, the mechanical arm device is not easy to maintain in the above-mentioned parking position 801 due to road bumps, so a locking mechanism is needed to limit the mechanical arm device in the parking position 801.

[0096] In view of the above problems, a preferred scheme is provided in the embodiments of the present application, as shown in Figure 4 The locking device 400 is installed on the support bracket 702, and the locking device 400 comprises:

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

[0098] The controller 401 can control the extension or retraction of the locking tongue 403;

[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 mechanical arm frame 101 to both sides. After entering the parking state, the locking tongue 403 can be extended by the controller, and whether the locking tongue 403 is extended / retracted can be confirmed by the position sensor. The position information of the locking tongue 403 needs to be confirmed before the mechanical arm frame 101 is driven to rotate.

[0101] In the process of implementing the present application, the inventor found that during transportation, the end of the sewage suction pipe 103 will swing irregularly with the bumps of the vehicle, which not only affects the driving safety, but also easily scratches the pipeline.

[0102] In view of the above problems, a preferred scheme is provided in the embodiments of the present application, as shown in Figure 5 The sewage suction pipe protection frame assembly 300 is installed on the mounting frame 701, and the sewage suction pipe protection frame assembly 300 is arranged below the naturally drooping sewage suction pipe 103 in the parking state. The sewage suction pipe protection frame assembly 300 comprises:

[0103] The protection support 301 is vertically installed on the mounting frame 701;

[0104] The fixed lock 303 includes a lock body and a lock catch. The lock body is arranged on the protection support 301 and has a semicircular groove recessed inward. The lock catch is a semicircular ring and is hingedly connected to one end of the lock body.

[0105] The rotating cover plate 302 is arranged on the lock body and is used to complete locking after the lock catch is closed with the lock body.

[0106] In the specific implementation, before transportation, the rotating cover plate 302 is opened, the lock catch is rotated to be fully opened, the suction pipe 103 is placed in the lock body, the lock catch is closed, and the rotating cover plate 302 is locked, so that the fixing of the suction pipe 103 in the storage state is completed. When reaching the vicinity of the work point, the suction pipe protection frame assembly 300 is unlocked again, and the suction pipe 302 is released. In the process of implementing the present application, the inventor finds that since the mechanical arm device can be locked in the storage state, a limiting assembly can also be installed at a position in the working state for further stabilizing the suction pipe during dredging.

[0107] To solve the above problems, a preferred scheme is provided in the embodiment of the present application. In the embodiment, only the mechanical arm device is limited at the second rotating position 803 as an example. It must be pointed out that the limiting assembly can not be installed only at this position.

[0108] As shown in Figure 1 and Figure 6 , the support bracket 702 is provided with a limiting assembly 600. The limiting assembly 600 includes:

[0109] The limiting mounting seat 602 is arranged on the support bracket 702 and is provided with a vertical insertion hole. A plurality of connecting bolts 603 are perpendicularly screwed on the limiting mounting seat 602.

[0110] The limiting mounting pin 601 is inserted into the insertion hole and is limited by the connecting bolts 603.

[0111] In implementation, the limiting assembly 600 is used in cooperation with the blocking block 109. The blocking block 109 is arranged on the support bracket 702. The installation position of the blocking block 109 is determined according to that the blocking block 109 can block the outward rotation of the mechanical arm frame 101 from the outside of the mechanical arm frame 101 when the mechanical arm device is located at the second rotation position 803. The installation position of the limiting mounting seat 602 and the final height of the limiting mounting pin 601 are determined according to that the limiting mounting pin 601 can block the inward rotation of the mechanical arm frame 101 from the inside of the mechanical arm frame 101 after the limiting mounting pin 601 is inserted into the insertion hole and tightened. The blocking block 109 and the limiting assembly 600 respectively complete the limiting of the inside and outside of the mechanical arm frame 101, and limit the mechanical arm device at the second rotation position 803. After the dredging work is completed, only the connecting bolt 603 needs to be loosened, the limiting mounting pin 601 is pulled out of the limiting mounting seat 602, and the inside of the mechanical arm frame 101 is released, so that the mechanical arm device can return along the original path.

[0112] It should be noted that the limiting assembly 600 provided in the embodiment can be replaced with the locking device 400. The driving device mentioned in the embodiment can adopt a hydraulic driving device or an electric driving device.

[0113] The mechanical arm device for a railway dredging vehicle and the railway dredging vehicle provided in the embodiment can realize the rotation of the whole device through the rotatable mechanical arm frame. The path length of the suction pipe on the arm can be adjusted through the telescopic mechanism. The winding and unwinding of the suction pipe can be realized through the rotatable suction pipe reel, so as to meet the operation requirements of different angles and depths. The guiding and auxiliary winding and unwinding of the suction pipe can be realized through the guiding mechanism. The suction and high-pressure flushing operations can be met through the suction pipe and the water pipe. The suction pipe port assembly with replaceable filter screen can meet various dredging requirements. The stable transportation can be realized through the protective support.
