Description

Technical Field

[0001] The utility model relates to the technical field of railway maintenance equipment, and more specifically to a railway sand removal device. Background Art

[0002] China is the country with the longest distribution of railways in desert areas, mainly concentrated in the northwest region. The wind and sand hazards in desert areas have always been the main factor that troubles the safe operation of railway lines. Due to sand hazards, train speed restrictions, suspension of operation and derailment often occur. In order to ensure the safe operation of railway lines in desert areas, the sand accumulated on the surface of the railway track bed must be cleaned regularly.

[0003] Based on the need to clean up the accumulated sand, in the related technology, the sand is removed by means of a sand removal vehicle and an excavator. Specifically, the accumulated sand on the surface of the railway track bed is cleaned up by a sand removal vehicle, and then the cleaned accumulated sand is transferred by an excavator. In this operation mode, the excavator and the sand removal vehicle need to work together, and the sand removal efficiency is low. In addition, for the cleaning of high-density accumulated sand, most sand removal vehicles are large-scale equipment, and the transfer and withdrawal time are long during use. The actual time for cleaning the accumulated sand during the window time is short, and the operation flexibility is poor. Therefore, the operation mode assisted by sand removal vehicles and excavators cannot meet the needs of fast and flexible sand removal from the railway track bed.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] The core of the utility model is to provide a railway sand removal device, which can be flexibly disassembled, assembled and transported, and can flexibly and efficiently clean the sand accumulated on the rails of the railway line, ensure the line traffic conditions, and ensure the safety of train driving.

[0035] The railway sand removal device provided by the utility model comprises a frame 3, a spiral sand pushing mechanism 1, a sand throwing mechanism 2 and a driving mechanism 6. Please refer to Figure 1 , Figure 4 .

[0036] A walking mechanism is provided at the bottom of the frame 3, and the walking mechanism specifically includes a running wheel 302 and a running auxiliary wheel 304. The running mechanism can realize the movement of the running wheel 302 and the running auxiliary wheel 304 on the rail 9 by manually pulling the mounting frame 301 of the frame 3, or can realize the movement of the running wheel 302 and the running auxiliary wheel 304 on the rail 9 by driving the power equipment. The design can be flexibly made according to the actual working conditions.

[0037] Taking a more preferred embodiment as an example, manually pulling the mounting frame 301 to move the running wheels 302 and the running auxiliary wheels 304 on the rails 9 can realize the movement of the entire sand removal device, which is simple and convenient to operate and does not require additional power equipment, reduces the weight of the entire device, and facilitates the disassembly, assembly and transportation of the device. The sand removal operation can be carried out by human power through the self-contained driving mechanism 6. After the operation is completed, the sub-components are disassembled and moved away from the railway, reducing the workload of line maintenance and repair, reducing construction costs, increasing the service life of the railway, and ensuring the safety of the operating state and the safety of the entire machine operation.

[0038] The spiral sand pushing mechanism 1 is detachably connected to the frame 3, and the sand throwing mechanism 2 is connected to the outlet end of the spiral sand pushing mechanism 1. When sand clearing is required, the sand throwing mechanism 2 and the spiral sand pushing mechanism 1 are both installed on the frame 3; when the sand removal device needs to be transported or transferred, the sand throwing mechanism 2 and the spiral sand pushing mechanism 1 can be removed from the frame 3. The sand throwing mechanism 2 and the spiral sand pushing mechanism 1 can be quickly disassembled or connected to the frame 3, so that each component can be transported, assembled and transferred under its own light weight, meeting the sand removal operation requirements of different sections, with stronger mobility and flexibility, and can be quickly disassembled and assembled within the skylight time, ensuring the flexibility and efficiency of the sand removal operation.

[0039] Optionally, the detachable connection in the above process can be connected by fasteners such as pins, bolts and nuts, as long as the connection strength is met.

[0040] The spiral sand pushing mechanism 1 is used to roll up the accumulated sand on the railway and spirally transport it to the exit end.

The side here is not limited to the side at one end or the side at both ends, and there is no limit on the distance of the side relative to the rail 9, as long as the sand removal requirements can be met.

[0041] Optionally, a receiving mechanism connected to the frame 3 may also be provided on the side of the rail 9 to receive the accumulated sand thrown by the sand throwing mechanism 2 so as to collect the sand for subsequent use or unified discharge.

[0042] Optionally, the spiral sand pushing mechanism 1 includes at least one set of spiral structures. The setting position of the spiral structure relative to the frame 3 can be designed according to actual conditions, and can be set in the middle, side, etc. The spiral structure can also be set to be adjustably connected to the frame 3 (the installation height position and installation length position of the spiral structure relative to the frame 3 are adjustable) to meet the cleaning needs of different situations in different sections of the road.

[0043] The driving mechanism 6 is used to drive the spiral sand pushing mechanism 1 and the sand throwing mechanism 2. The operation of the driving mechanism 6 can realize the collection and throwing operations of the accumulated sand without the need for auxiliary devices, thereby improving the efficiency of sand cleaning, meeting the needs of fast and flexible sand removal from the railway track bed, ensuring the opening of the line, and ensuring the safety of train operation.

[0044] The above-mentioned railway sand removing device includes a frame 3, a spiral sand pushing mechanism 1, a driving mechanism 6 and a sand throwing mechanism 2, wherein a walking device is provided at the bottom of the frame 3, and the walking device can move relative to the rail 9 to realize the movement of the sand removing device; the spiral sand pushing mechanism 1 is detachably connected to the frame 3, and the spiral sand pushing mechanism 1 is connected to the outlet end of the sand throwing mechanism 2. The spiral sand pushing mechanism 1 and the sand throwing mechanism 2 can be quickly removed or installed from the frame 3 according to the situation, so as to realize the needs of carrying, assembling and transporting each component under light weight, meet the needs of rapid sand clearing in different sections, have stronger mobility and flexibility, and ensure the efficiency of sand clearing; the spiral sand pushing mechanism 1 can roll up the accumulated sand at the rail and spirally transport it, and the sand throwing mechanism 2 is connected to the outlet end of the spiral sand pushing mechanism 1 to throw the accumulated sand spirally transported by the spiral sand pushing mechanism 1 to the side of the rail 9, and the sand throwing mechanism 2 and the spiral sand pushing mechanism 1 can be driven by the driving mechanism 6 to complete the rolling and cleaning of the accumulated sand on the rail, thereby improving the efficiency of sand clearing. The above-mentioned railway sand removal device can flexibly and efficiently clean the sand accumulated on the rails of the railway line, ensure the conditions for line traffic, and ensure the safety of train driving.

[0045] On the basis of the above embodiment, the spiral sand pushing mechanism 1 includes a support frame 102 detachably connected to the frame 3, a spiral wire drum 101 is arranged in the frame of the support frame 102, the bottom height of the spiral wire drum 101 is less than the bottom height of the support frame 102, and the driving mechanism 6 drives the spiral wire drum 101 to rotate relative to the support frame 102.

[0046] Please refer to Figure 1 , Figure 2 The spiral sand pushing mechanism 1 includes a support frame 102, which is detachably connected to the frame 3. The spiral drum 101 is arranged in the support frame 102, or it can be said that the support frame 102 is covered on the spiral drum 101 to effectively protect it and prevent sand from flying and affecting the life of the components and the sand cleaning efficiency.

[0047] In this embodiment, through the detachable connection between the support frame 102 and the frame 3, the detachable connection between the spiral sand pushing mechanism 1 and the frame 3 is essentially realized, and the detachable connection between the spiral sand pushing mechanism 1 and the sand throwing mechanism 2 and the frame 3 is realized, so that the sand removal device can be quickly disassembled, and the transportation, transfer and assembly requirements of each component under light weight are realized, with strong mobility and flexibility.

[0048] The bottom height of the spiral drum 101 is smaller than the bottom height of the support frame 102. When the driving mechanism 6 drives the spiral drum 101 to rotate relative to the support frame 102, the spiral drum 101 contacts the accumulated sand and spirally rotates to roll up the accumulated sand. The bottom of the support frame 102 will not contact the accumulated sand, thereby ensuring the reliable and safe operation of the sand removal device.

[0049] The spiral angle of the spiral drum 101 can be flexibly set according to the actual operation conditions and is not limited here.

[0050] Based on any of the above embodiments, the spiral drum 101 includes a rotating shaft and a spiral blade spirally arranged around its axial direction. The spiral blade has an output gap at one end close to the sand throwing mechanism 2 and the inner wall of the support frame 102. A conveying plate 105 is provided in the output gap for delivering the accumulated sand to the sand throwing mechanism 2.

[0051] Please refer to Figure 1 , Figure 2 The spiral drum 101 includes a rotating shaft and spiral blades spirally arranged around its axis. The driving mechanism 6 drives the spiral blades to rotate through the rotating shaft to achieve the effect of rolling up sand and transporting sand.

[0052] One end of the spiral blade close to the sand throwing mechanism 2, which can also be said to be the tail end of the spiral blade spiral line, is the outlet end of the spiral line drum 101. There is an output gap between the outlet end and the inner wall of the support frame 102. A conveying plate 105 is provided in the output gap. The conveying plate 105 can be set at a certain inclination angle to deliver the accumulated sand at the outlet end of the spiral line drum 101 to the sand throwing mechanism 2 for throwing the accumulated sand.

[0053] On the basis of any of the above embodiments, both sides of the support frame 102 are connected to the frame 3 via a disassembly connection mechanism 4;

[0054] The disassembly connection mechanism 4 includes a connection sleeve 401 and a connection pin 402 fixedly mounted thereon. One of the connection pin 402 and the connection sleeve 401 is connected to the support frame 102 , and the other is connected to the frame 3 .

[0055] Please refer to Figure 1 , Figure 2 , Figure 5 The disassembly and assembly connection mechanism 4 is detachably connected to the frame 3 to realize the detachable connection between the support frame 102 and the frame 3, that is, the detachable connection between the spiral sand pushing mechanism 1 and the sand throwing mechanism 2 and the frame 3 is realized, so that the spiral sand pushing mechanism 1 and the sand throwing mechanism 2 can be quickly installed or disassembled from the frame 3.

[0056] Specifically, the disassembly and assembly connection mechanism 4 includes a connection sleeve 401 and a connection pin 402 fixedly sleeved therewith, and the two are aligned through the hole positions. There is no restriction on the sleeve relationship between the two, and one can be sleeved inside and the other outside.

[0057] One of the connecting pin 402 and the connecting sleeve 401 is connected to the support frame 102, and the other is connected to the frame 3. The connection method here can be an integral structure. For example, the connecting sleeve 401 can be welded or directly processed into one with the frame 3, and the connecting sleeve 401 moves with the frame 3 during assembly and disassembly; it can also be a detachable connection. For example, corresponding to the above process, the connecting sleeve 401 can be detachably connected to the frame 3. When assembly is required, the frame 3 is attached to the connecting sleeve 401. When disassembly is required, the connecting sleeve 401 can be removed separately. Under the premise of facilitating the assembly operation effect, the preferred connection method is a detachable connection.

[0058] Taking a more preferred embodiment as an example, the connecting pin 402 is fixed in the connecting sleeve 401 and is detachably connected to the frame 3, and the connecting sleeve 401 is detachably connected to the support frame 102, forming a detachable connection between the sand throwing mechanism 2, the frame 3, and the spiral sand pushing mechanism 1, which is convenient for the handling, combination, and transportation of the three, and improves the overall flexibility of the sand removal device.

[0059] Optionally, in order to ensure the strength of the connection between the sand throwing mechanism 2, the frame 3 and the spiral sand pushing mechanism 1, the connecting sleeve 401 can be connected to the frame 3 on the basis that the connecting sleeve 401 is detachably connected to the support frame 102, thereby increasing the connection points with the frame 3 and ensuring the reliability of the overall structure.

[0060] Based on any of the above embodiments, the disassembly and assembly connection mechanism 4 also includes an anti-slip pin 403 passing through the connecting pin 402 and the connecting sleeve 401, the anti-slip pin 403 connects the side of the frame 3 in the length direction, and one of the connecting pin 402 and the connecting sleeve 401 connects the side of the frame 3 in the width direction.

[0061] Please refer to Figure 1 , Figure 2 , Figure 5 The anti-drop pin 403 passes through the frame 3, the connecting sleeve 401 and the connecting pin 402 to achieve a reliable connection between the support frame 102 and the frame 3. The anti-drop pin 403 is set to prevent the connecting sleeve 401 and the connecting pin 402 from falling off, thereby ensuring the reliability and strength of the overall structure after the combined connection.

[0062] The anti-drop pin 403 connects the side of the frame 3 in the length direction, and one of the connecting pin 402 and the connecting sleeve 401 connects the side of the frame 3 in the width direction. That is, the disassembly and assembly connection mechanism 4 has connection points in both the length and width directions of the frame 3, ensuring that the assembled sand removal device has good stability and reliability, and ensuring reliable and stable operation of the components.

[0063] Optionally, a limiting portion may be provided at the end of the connecting pin 402. When the connecting pin 402 and the connecting sleeve 401 are connected, the limiting portion abuts against the support frame 102, thereby limiting the displacement of the disassembly and assembly connecting mechanism 4 while achieving a positioning effect during connection.

[0064] Based on any of the above embodiments, the sand throwing mechanism 2 includes a sand receiving cylinder 202, which is arranged at the outlet end of the spiral drum 101 and has an ejection impeller 201 inside.

The top of the sand receiving cylinder 202 is connected with a sand throwing cylinder 203. The specific length of the sand throwing cylinder 203 is not limited. The ejection impeller 201 is driven to rotate by the driving mechanism 6 to realize the throwing up of the sand in the sand receiving cylinder 202. The thrown up accumulated sand is sent to the side of the rail 9 through the sand throwing cylinder 203 to achieve the sand clearing effect.

[0066] The blades used by the ejection impeller 201 are based on achieving a good ejection effect, and their types, structural parameters, etc. are not limited. For example, one or more outer arc structures can be provided to guide the accumulated sand thrown up by the ejection impeller 201 to the side of the rail 9. The outer arc structure here means that the end of the arc extends toward the side of the rail 9, and the end of the arc is the position of the sand ejection outlet.
