Description

Technical Field

[0001] This invention relates to the field of automatic sand recovery technology for locomotive sand spreading tests, and specifically to an automatic locomotive sand collection device resistant to environmental interference. Background Technology

[0002] Sand is a crucial safety medium in railway locomotive operation. When locomotives start, go uphill, or when the tracks are wet and slippery in rainy weather, sand is sprayed onto the rail surface through a sand-spraying system. This can significantly increase the adhesion coefficient between the wheel and rail, prevent wheel slippage and wheel spin, and ensure the effective transmission of locomotive traction and braking force. It is one of the key measures to ensure the safety and efficiency of railway transportation.

[0003] To ensure the reliable operation of the sand-spreading system when needed, regular performance tests and maintenance of the locomotive's sand-spreading system are required. During testing, the locomotive spreads sand onto the rail surface and trackside area while stationary or running at low speed. Currently, there is no dedicated, efficient, automated equipment for recovering the sand spilled during testing. The commonly used recovery method is as follows: a simple stainless steel sheet or similar collection plate is laid on the trackside ground; during the online sand-spreading test, a large amount of sand does not fall entirely onto the rail surface due to the inertia of the spray and the influence of wind direction, but is widely scattered in the trackside area and railhead area on both sides of the rail. After the locomotive leaves, a small amount of sand left on the rail surface will be repeatedly crushed by the wheels of subsequent locomotives and passively fall onto the steel plate beside the rail; maintenance personnel regularly clean and collect the sand scattered on the steel plate.

[0004] However, the traditional method of "laying steel plates + manual recycling" has the following shortcomings: the sand recycling rate is extremely low, resulting in poor economic benefits; labor costs are high and labor intensity is high; the working environment is harsh and safety and health risks are high; and this recycling method relies entirely on manual operation, which is seriously out of step with the development direction of automation and intelligence pursued by modern railway technology. It cannot achieve the timeliness, accuracy and data management of sand recycling, thus restricting the improvement of the overall efficiency of maintenance operations.

[0005] Therefore, there is an urgent need for an automatic sand collection device for locomotives that enables sand recycling, has low labor costs, low operational risks, and a high degree of automation. Summary of the Invention

[0011] Furthermore, the outer nozzle structure includes multiple outer rail surface nozzles, outer sand collecting nozzles, and multiple outer float nozzles. The outer rail surface nozzles are respectively disposed on the outer end baffle and located above the outer sand collecting slope. The outer sand collecting nozzles are disposed on the outer end baffle opposite to the outer sand suction port. The outer float nozzles are spaced apart on the outer sand collecting cover and are respectively attached to the outer float.

[0012] Furthermore, the inner frame includes an inner sand collection cover plate and two inner end baffles. The inner sand collection cover plate is arranged parallel to the guide rail, and the inner end baffles are respectively arranged perpendicularly on both sides of the inner sand collection cover plate.

Therefore, they should not be construed as limitations on this invention.

[0022] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0023] Example: like Figure 1 , Figure 2 and Figure 9 As shown, this embodiment provides an automatic locomotive sand collection device resistant to environmental interference, including two guide rail fixing blocks 1, an outer sand collection body 2, and an inner sand collection body 3. This device is arranged on both sides of a single guide rail, and both guide rails are equipped with this device. The device is arranged along the direction of track travel according to the locomotive model, covering all types of vehicles in the locomotive depot. The installation space dimensions of this device meet the basic building clearance requirements of railway clearance. Before collecting sand, this device automatically cleans the exposed sand collection surface and the rail surface to keep them clean and dry. Before the locomotive sand spreading test ends, this device automatically collects the sand on the rail surface and beside the rail, ensuring that the sand is not damaged by the wheels and can be recycled for secondary use without the need for manual on-site recovery.

[0024] Specifically, the guide rail fixing blocks 1 are arranged parallel to each other at intervals at the bottom of the guide rail. The outer sand collecting body 2 and the inner sand collecting body 3 are both set on the guide rail fixing blocks 1 and are respectively set on both sides of the guide rail. The outer sand collecting body 2 and the inner sand collecting body 3 are both open structures, and the openings are both set towards the guide rail. The outer sand collecting body 2 is set higher than the guide rail, and the inner sand collecting body 3 is set lower than the guide rail. The outer sand collecting body 2 and the inner sand collecting body 3 do not interfere with the space of the track clamps, fixing bolts, etc.

[0025] Specifically, such as Figure 3 As shown, the guide rail fixing block 1 includes a rail bottom mounting plate 11, a rail bottom clamping block 12, and two fixing posts 13. The rail bottom mounting plate 11 is a cuboid that passes through the bottom of the guide rail and is perpendicular to the guide rail. The rail bottom clamping block 12 is welded and fixed to the middle of the top surface of the rail bottom mounting plate 11. The rail bottom clamping block 12 is clamped to both sides of the guide rail from the bottom of the guide rail to fix the device. In this embodiment, the rail bottom clamping block 12 is the prior art. The fixing posts 13 are welded and fixed to the top surface of the rail bottom mounting plate 11 near the two side edges. The two fixing posts 13 provide installation interfaces for the outer sand collecting body 2 and the inner sand collecting body 3, respectively.

[0026] In this embodiment, the outer sand collecting body 2 is used to collect the sand that falls off during the sand spreading test and to self-clean, while cleaning the rail surface and blowing the sand from the rail surface into the inner sand collecting body 3. The outer sand collecting body 2 includes an outer frame, an outer sand collecting structure, an outer nozzle structure, and an outer vibration assembly. The outer sand collecting structure is located inside the outer frame, the outer nozzle structure is located on the outer frame, and the outer vibration assembly is located diagonally below the outer sand collecting structure.

[0027] Specifically, the outer frame includes an outer sand collection cover plate 23 and two outer end baffles 212. The outer sand collection cover plate 23 has an inverted L-shaped cross section. The outer sand collection cover plate 23 is set parallel to the guide rail and covers the outer sand collection structure. The outer end baffles 212 are welded and fixed to both sides of the outer sand collection cover plate 23 and are set perpendicular to the guide rail. Through the outer sand collection cover plate 23 and the outer end baffles 212, the recycling process is not affected by weather factors, which can effectively prevent sand from being damaged or polluted by the open environment, ensure that the recycled sand can be reused, and significantly reduce the cost of consumables.

[0028] like Figures 4-6As shown, the outer sand collecting structure includes an outer sand collecting inclined surface 21, an outer vertical baffle 22, an outer floating plate 24, an outer sand suction port 210, and an outer sand collecting trough 29. The outer sand collecting inclined surface 21 has an opening at the top. One end of the outer sand collecting inclined surface 21 is located at the bottom of the guide rail surface, and the other end is located inside the outer sand collecting body 2. The two ends of the outer sand collecting inclined surface 21 parallel to the guide rail direction are welded and fixed to the outer end baffle 212 respectively. The outer vertical baffle 22 is set above the end of the outer sand collecting inclined surface 21 away from the guide rail, and the top of the outer vertical baffle 22 is welded and fixed to the inner wall of the outer sand collecting cover plate 23. The outer sand collecting trough 29 is set below the outer sand collecting inclined surface 21, and both ends of the outer sand collecting trough 29 are welded and fixed to the outer end baffle 212 respectively. One side of the outer sand collecting trough 29 is tightly fitted to the bottom of the outer sand collecting inclined surface 21, and the other side is tightly fitted to the outer sand collecting inclined surface 21. The outer sand collecting slope 21 forms an opening structure, and the opening end of the outer sand collecting slope 21 is slightly longer than the opening end of the outer sand collecting trough 29. The outer float 24 is set on the side where the outer sand collecting slope 21 and the outer sand collecting trough 29 form an opening, and there is a gap between it and the opening side, so that the lower part of the outer sand collecting trough 29 and the bottom of the outer float 24 form an opening and communicate with the outside. The two ends of the outer float 24 are respectively rotatably connected to the outer end baffle 212, and the top of the outer float 24 is set higher than the outer sand collecting slope 21. The outer sand suction port 210 is set on the outer end baffle 212 on one side and communicates with the outer sand collecting trough 29. The outer sand collecting slope 21 further protects the outer sand collecting trough 29, so that the outer sand collecting trough 29 is not affected by rain and snow weather, and can effectively block rainwater and water accumulation from entering the outer sand collecting trough 29, so as to ensure the quality of sand storage.

[0029] In this embodiment, a negative pressure sand suction pipe is connected to the outside of the outer sand suction port 210, and the end of the negative pressure sand suction pipe away from the outer sand suction port 210 is connected to a storage device.

[0030] The outer nozzle structure includes two outer rail surface nozzles 28, an outer sand collecting nozzle 26, and two outer float nozzles 25. The two outer rail surface nozzles 28 are symmetrically welded and fixed to the two outer end baffles 212 and located above the outer sand collecting slope 21. The outer rail surface nozzles 28 can blow the sand on the rail surface to the upper surface of the inner sand collecting body 3. The rail surface cleaning adopts a nozzle design, which can cover a wide range of rail direction to ensure cleaning without dead corners. On the other hand, it can accurately control the lateral splash range of the rail surface sand to prevent sand from falling into non-recovery areas and improve the recovery efficiency. The airflow velocity of the nozzles close to the rail surface is low, and the airflow velocity of the nozzles cleaning the rail surface further away is high. The outer sand collecting nozzles 26 are set on the outer end baffles 212 opposite to the outer sand suction port 210 and are connected to the outer sand collecting groove 29. The outer float nozzles 25 are spaced apart on the outer sand collecting cover plate 23 and are respectively connected to the outer float plate 24 through the outer sand collecting cover plate 23.

[0031] In this embodiment, the outer rail surface nozzle 28 is a circular nozzle, and the outer rail surface nozzle 28 is provided with two air jets. One air jet has a large aperture and is located near the outer end baffle 212, forming a 30° angle with the rail. It is used to blow air to a distant location, reaching the middle position of the track covered by the device. The other air jet has a small aperture and is located at the end of the large air jet that is away from the outer end baffle 212, forming an 80° angle with the rail. It is used to blow air to the nearby track. The air jet range of the two outer rail surface nozzles 28 is half the length of the track of the device.

[0032] In this embodiment, two outer sleeves 211 are vertically welded and fixed at intervals at the bottom of the outer sand collecting body 2. The diameter of the outer sleeves 211 is larger than the diameter of the fixed column 13. The outer sleeves 211 are respectively inserted into the fixed column 13. The pluggable method allows for quick connection and removal without the need for complex modifications to the track foundation. This effectively avoids interference from traditional equipment on daily track maintenance operations and greatly improves the convenience of operation and maintenance.

[0033] The outer vibration component is an outer vibration motor 27, which is welded and fixed to the outer wall of the outer sand collection trough 29. The outer vibration motor 27 is waterproof with a waterproof rating of IP67.

[0034] Before sand collection begins, the outer vibration motor 27 is turned on to clean the surface of the outer sand collection slope 21 and the outer vertical baffle 22. At this time, the outer float nozzle 25 is not working, and the foreign objects on the outer vertical baffle 22 fall onto the outer sand collection slope 21. Since the outer sand collection slope 21 covers the outer sand collection trough 29 in the horizontal direction, water droplets and surface foreign objects fall to the ground through the opening formed between the outer sand collection trough 29 and the outer float 24, and will not enter the outer sand collection trough 29.

[0035] During sand collection, the outer float nozzle 25 starts working, and the outer float 24 is blown up by the outer float nozzle 25, so that the bottom of the outer float 24 is located in the outer sand collection trough 29. During the sand spreading test, the sand that falls on the outside lands on the outer sand collection slope 21. Some of the horizontally splashed sand is guided by the outer vertical baffle 22 to land on the outer sand collection slope 21. Guided by the floating outer float 24, some of the sand on the outer sand collection slope 21 falls into the outer sand collection trough 29.

[0036] After the sand collection work is completed, the outer vibration motor 27 is turned on to clean the sand on the outer sand collection slope 21 and the outer vertical baffle 22. When all the sand falls into the outer sand collection trough 29, the outer sand collection nozzle 26 starts to spray air, blowing the sand towards the outer sand suction port 210. Then, the sand is collected into the storage container through the negative pressure sand suction pipe, thus completing the sand collection.

[0037] In this embodiment, the inner sand collecting body 3 is used to collect sand from the rail surface and sand falling during the sand spreading test, and at the same time performs self-cleaning. The inner sand collecting body 3 includes an inner frame, an inner sand collecting structure, an inner nozzle structure, and an inner vibration component. The inner sand collecting structure is located inside the inner frame, the inner nozzle structure is located on the inner frame, and the inner vibration component is located diagonally below the inner sand collecting structure.

[0038] The inner frame includes an inner sand collection cover plate 33 and two inner end baffles 38. The inner sand collection cover plate 33 is arranged parallel to the guide rail, and the inner end baffles 38 are respectively arranged perpendicularly on both sides of the inner sand collection cover plate 33. The inner end baffles 38 do not interfere with the space of the locomotive wheel flange.

[0039] like Figure 7 and Figure 8 As shown, the inner sand collecting structure includes an inner sand collecting inclined surface 31, an inner vertical baffle 32, an inner floating plate 34, an inner sand suction port, and an inner sand collecting trough 39. The inner vertical baffle 32 is located above the inner sand collecting inclined surface 31, the inner sand collecting trough 39 is located below the inner sand collecting inclined surface 31, the inner floating plate 34 is located on one side of the inner sand collecting inclined surface 31 and the inner sand collecting trough 39, and the inner sand suction port is located on the inner end baffle 38 and communicates with the inner sand collecting trough 39.

[0040] The inner nozzle structure includes an inner sand collecting nozzle and two inner float nozzles 35. The inner sand collecting nozzle is disposed on the inner end baffle 38 opposite to the inner sand suction port. The inner float nozzles 35 are spaced apart on the inner sand collecting cover plate 33 and are respectively attached to the inner float 34.

[0041] Two inner sleeves 36 are spaced apart at the bottom of the inner sand collecting body 3, and the inner sleeves 36 are mounted on the fixed column 13.

[0042] The inner vibration component is an inner vibration motor 37, which is located on the outside of the inner sand collection trough 39.

[0043] In this embodiment, the inner sand collecting body 3 is identical to the outer sand collecting body 2 in structure and function, except that it does not have a rail surface nozzle.

[0044] In this embodiment, the outer sand collecting body 2 is provided with an air supply pipeline 4 that is connected to the outer rail surface nozzle 28, the outer sand collecting nozzle 26 and the outer float nozzle 25 respectively, and the inner sand collecting body 3 is provided with an air supply pipeline 4 that is connected to the inner sand collecting nozzle and the inner float nozzle 35 respectively.

[0045] The working process of this embodiment is as follows: Before the locomotive enters the sand-spreading test area, the outer rail surface nozzle 28 is turned on to clean the rail surface, and then the outer vibration motor 27 is turned on to clean the foreign objects on the outer sand-collecting slope 21 and the outer vertical baffle 22. At the same time, the inner vibration motor 37 is turned on to clean the foreign objects on the inner sand-collecting slope 31 and the inner vertical baffle 32, as well as the rail surface foreign objects that have fallen onto the inner sand-collecting body 3.

[0046] The locomotive is stopped at a relatively fixed track position, and the driver conducts a sand-spreading test. At the same time, the outer float nozzle 25 and the inner float nozzle 35 are turned on. The sprayed sand falls on the track surface and the outer sand-collecting body 2 and the inner sand-collecting body 3 beside the track. After the sand-spreading test is completed, the outer track surface nozzle 28 is turned on to collect the track surface sand obliquely from the outside to the inside of the track. The high-pressure airflow blows the sand that falls on the track surface onto the inner sand-collecting body 3.

[0047] The sand falls onto the outer sand collecting slope 21 and the outer vertical baffle 22 of the outer sand collecting body 2. Under the action of the outer vibration motor 27, the sand quickly falls out of the outer sand collecting slope 21 and the outer vertical baffle 22 and falls onto the outer float 24. The outer float 24 guides the sand to fall into the outer sand collecting trough 29. When the sand falls into the outer sand collecting trough 29, the outer sand collecting nozzle 26 starts to spray air, guiding the sand to the outer sand suction port 210. The sand is collected into the storage container through the negative pressure sand suction pipe, thus completing the collection of sand in the outer sand collecting body 2.

[0048] The sand falls onto the inner sand collecting inclined surface 31 and the inner vertical baffle 32 of the inner sand collecting body 3. Under the action of the inner vibration motor 37, the sand quickly falls out of the inner sand collecting inclined surface 31 and the inner vertical baffle 32 and falls onto the inner float plate 34. The inner float plate 34 guides the sand to fall into the inner sand collecting trough 39. When the sand falls into the inner sand collecting trough 39, the inner sand collecting nozzle starts to spray air, guiding the sand to the inner sand suction port. The sand is collected into the storage container through the negative pressure sand suction pipe, thus completing the collection of sand in the inner sand collecting body 3.

[0049] The above examples illustrate the present invention only to aid in understanding it and are not intended to limit the scope of the invention. Those skilled in the art can make various simple deductions, modifications, or substitutions based on the ideas of this invention.
