Description

Dust removal equipment for medium-sized intelligent rail grinding vehicles in railways Technical Field

[0001] This utility model relates to the technical field of dust removal equipment, and in particular to a dust removal device for a medium-sized intelligent rail grinding vehicle used in railways. Background Technology

[0002] With the rapid development of railway transportation, the rail system has continuously expanded. Whether it's the main railway lines carrying high-capacity transport or the subway network serving urban commuters, their scale is constantly growing, resulting in a significant increase in the number of rails. Rails are subjected to immense pressure and wear over long periods, making their surfaces highly susceptible to various damages such as wavy wear, rail surface abrasion, severe railside wear, cracks, and railhead crushing. These damages not only affect the smoothness of train operation, leading to a poorer passenger experience, but also pose a threat to train operation safety. Therefore, regular rail grinding and maintenance has become a necessary measure to ensure the safe and efficient operation of railways.

[0003] When medium-sized intelligent rail grinding vehicles perform grinding tasks, they use high-speed rotating grinding wheels to grind the surface of the rails, generating a large amount of metal dust, such as iron powder and iron filings. If this dust is not controlled, it will disperse unchecked. On the one hand, the spread of dust will seriously pollute the ecological environment along the railway line, negatively impacting the surrounding soil, water bodies, and vegetation; on the other hand, for residents along the line, the dust in the air will reduce the quality of their living environment, threaten their health, and increase the risk of respiratory diseases.

[0004] At the operational site of the medium-sized intelligent rail grinding vehicle on the railway, a large amount of dust filled the surrounding area. Workers exposed to this environment for extended periods, even with protective gear, could not completely avoid inhaling dust, posing a significant risk of occupational diseases such as pneumoconiosis. Furthermore, the pervasive dust interfered with the workers' vision, reduced operational precision, increased the probability of errors, and seriously impacted operational safety.

[0005] If large amounts of dust accumulate around the grinding vehicle, they will enter the mechanical parts and electrical equipment, accelerating wear and tear, causing malfunctions, increasing maintenance costs, and extending downtime. This will reduce the efficiency and quality of the grinding operation, hindering the smooth progress of the grinding work. Therefore, developing a suitable dust removal system for medium-sized intelligent railway rail grinding vehicles has become an urgent priority. Summary of the Invention

[0006] In order to solve the problems existing in the prior art, this utility model provides a medium-sized intelligent rail grinding vehicle dust removal equipment for railways.

[0007] The present invention provides a medium-sized intelligent dust removal device for railway rail grinding vehicles, which adopts the following technical solution:

[0008] A dust removal device for a medium-sized intelligent rail grinding vehicle for railways includes a dust removal box installed on the grinding vehicle. The dust removal box has a receiving cavity, and a dust removal bag is installed in the receiving cavity. A guide channel communicating with the receiving cavity is installed on the dust removal box. An exhaust pipe communicating with the dust removal unit of the grinding vehicle is connected to the guide channel. A drawer that can be detachably fixed to the dust removal box is connected to the opening of the dust removal bag. An axial flow fan fixed to the dust removal box is installed on the side of the drawer. The axial flow fan, the drawer and the dust removal bag are connected.

[0009] By adopting the above technical solution, during the grinding process of the steel rail, the axial flow fan is turned on, creating a negative pressure environment inside the dust collector bags. Dust at the grinding unit is absorbed by the exhaust pipe, with dust particles adsorbed on the outside of the dust collector bags. The filtered gas passes through the inside of the dust collector bags and the drawer before being discharged by the axial flow fan. The drawer is detachable and can be used to clean dust particles from the outer surface of the dust collector bags. After cleaning, the dust collector bags can be reinstalled and secured. This dust removal equipment, used in conjunction with the grinding cart, achieves continuous and efficient dust removal while grinding, effectively solving problems such as dust pollution of the surrounding environment and impact on the health of workers.

A handle is provided on the outside of the outer sealing plate, and a support rod is connected between the outer sealing plate and the inner sealing plate.

[0011] By adopting the above technical solution, the outer sealing plate, the inner sealing plate and the support rod form a space for exhaust. The axial flow fan is connected to this space to form an exhaust path. When the dust collector bag needs to be cleaned, the drawer and dust collector bag can be pulled out by the handle.

[0012] Optionally, an elastic element is connected between the outer sealing plate and the support rod to elastically compress the support rod and the inner sealing plate.

[0013] By adopting the above technical solution and setting up elastic elements, the overall sealing performance is further improved.

[0014] Optionally, the elastic element includes a fixed plate fixed to the end of the support rod, a screw fixed to the inner side of the outer sealing plate, the screw sliding through the fixed plate, a nut installed at the end of the screw, and a compression spring sleeved on the screw, the compression spring elastically supporting the outer sealing plate and the fixed plate.

[0015] By adopting the above technical solution, the compression spring elastically squeezes the fixing plate, thereby making the inner sealing plate and the sealing ring fit tightly together and improving the sealing performance.

[0016] Optionally, a clamping mechanism is provided between the outer sealing plate and the dust collector housing. The clamping mechanism includes a fixed seat fixed on the side wall of the dust collector housing located on both sides of the outer sealing plate. The top of the fixed seat is provided with an L-shaped limiting groove. It also includes a stop rod 1 that can be detachably locked in the limiting groove and a stop rod 2 for pushing the outer sealing plate. A connecting rod is fixed between the stop rod 1 and the stop rod 2. An operating rod is also vertically fixed on the stop rod 1 and the stop rod 2.

[0017] By adopting the above technical solution, the positions of stop lever one and stop lever two can be controlled by the operating lever to facilitate opening or fixing the drawer.

[0018] Optionally, the guide channels are provided in two rows and located on both sides of the dust collector bag, with the extension direction of the guide channels perpendicular to the extension direction of the dust collector bag.

[0019] By adopting the above technical solution and setting up multiple drainage channels, dust can be effectively absorbed.

[0020] Optionally, multiple dust collector bags are provided and arranged in a matrix within the receiving cavity.

[0021] By adopting the above technical solution, the space of the receiving cavity is made reasonable, which facilitates the installation or removal of the dust collector bag.

[0022] Optionally, the dust collector bag includes a bag body and a frame for supporting the bag body.

[0023] By adopting the above technical solution, the skeleton rigidly supports the bag body, keeping the bag body in a taut state, so as to effectively filter dust and allow gas to pass through. Attached Figure Description

[0030] The present invention will be further described in detail below with reference to Figures 1-5.

[0031] This utility model discloses a dust removal device for a medium-sized intelligent rail grinding vehicle. Referring to Figures 1-5, the dust removal device for the medium-sized intelligent rail grinding vehicle includes a dust removal box 1, which is installed at the bottom of the grinding vehicle. The dust removal box 1 has a receiving cavity 10 inside, and multiple dust removal bags 2 are arranged in a matrix inside the receiving cavity 10. Each dust removal bag 2 includes a bag body and a frame for supporting the bag body, so that the dust removal bag 2 is in a stable cylindrical shape. Two rows of guide channels 3 are installed inside the dust removal box 1 along the extension direction of the dust removal bags 2. The two rows of guide channels 3 are located on both sides of the multiple dust removal bags 2. The extension direction of the guide channels 3 is perpendicular to the extension direction of the dust removal bags 2. One end of the guide channel 3 is closed, and the other end of the guide channel 3 is connected to the receiving cavity 10.

[0032] The bottom of the closed end of the guide channel 3 is vertically connected to an exhaust pipe 4 via a stainless steel hose clamp. The exhaust pipe 4 is a high-temperature resistant flexible hose that can be flexibly connected and stably transport gas. The exhaust pipe 4 is directly connected to the grinding unit of the grinding machine, that is, the dust generated during the grinding of the rail is absorbed through the exhaust pipe 4. The open end of the dust collector bag 2 is equipped with a drawer 5 for taking out or installing the dust collector bag 2. The drawer 5 includes an outer sealing plate 50 and an inner sealing plate 51 arranged vertically and in parallel. The outer sealing plate 50 and the inner sealing plate 51 are connected by multiple support rods 52. The support rods 52 can be made of angle steel. A handle 500 is fixed to the outside of the outer sealing plate 50. The inner sealing plate 51 has a hole corresponding to the position of the dust collector bag 2, and the open end of the dust collector bag 2 is fixed in the hole.

[0033] Axial flow fans 6 are fixed to the dust collection box 1 on both sides of drawer 5. The exhaust direction of the axial flow fans 6 is perpendicular to the extension direction of the dust collection bag 2. The axial flow fans 6 are connected to drawer 5, thereby generating a strong airflow suction force through the axial flow fans 6, creating negative pressure in drawer 5, dust collection bag 2, guide channel 3 and exhaust pipe 4, thereby absorbing the dust generated after the grinding machine grinds the steel rails. The particles in the dust are blocked by the bag body of dust collection bag 2 and adhere to the outside of the bag body, while the filtered gas enters dust collection bag 2 and drawer 5 in sequence and is discharged through axial flow fans 6.

[0034] On the inner wall of the dust collector housing 1, elastic sealing rings 11 are fixed at positions corresponding to the outer sealing plate 50 and the inner sealing plate 51, respectively, and the outer sealing plate 50 and the inner sealing plate 51 are in sealing contact with the corresponding sealing rings 11. To improve the sealing performance, an elastic element 53 is also provided between the outer sealing plate 50 and the support rod 52. The elastic element 53 includes a fixing plate 530 fixed to the end of the support rod 52. A screw 531 is vertically fixed to the side of the outer sealing plate 50 near the support rod 52. The screw 531 slides through the fixing plate 530. A nut 532 is threaded on the end of the screw 531 away from the outer sealing plate 50. The nut 532 is located on the side of the fixing plate 530 away from the outer sealing plate 50. A compression spring 533 is also sleeved on the screw 531. The compression spring 533 elastically supports the outer sealing plate 50 and the fixing plate 533. Through the elastic compression of the compression spring 533, the inner sealing plate 51 and the sealing ring 11 are made to have a tighter contact.

[0035] A clamping mechanism 7 for fixing the outer sealing plate 50 is provided between the dust collector 1 and the outer sealing plate 50. The clamping mechanism 7 includes a fixing seat 70 fixed to the side wall of the dust collector 1 located on both sides of the outer sealing plate 50. The top of the fixing seat 70 is provided with an L-shaped limiting groove 700. The clamping mechanism 7 also includes a first stop bar 71 and a second stop bar 72 arranged in parallel. Multiple connecting rods 73 are fixed between the first stop bar 71 and the second stop bar 72. An operating rod 74 is vertically fixed to the first stop bar 71 and the second stop bar 72. The first stop bar 71 is used to lock and fix in the limiting groove 700. The second stop bar 72 is used to push the outer sealing plate 50, so that the outer sealing plate 50 is in close contact with the sealing ring 11, effectively preventing dust leakage and fixing the entire drawer 5.

[0036] The implementation principle of the dust removal equipment for a medium-sized intelligent rail grinding vehicle in this embodiment of the invention is as follows: During the rail grinding process, the axial flow fan 6 is turned on, creating a negative pressure environment inside the dust collector bags 2. The dust at the grinding unit is absorbed by the exhaust pipe 4, with dust particles adsorbed on the outside of the dust collector bags 2. The filtered gas is discharged by the axial flow fan 6 after passing through the inside of the bags and the drawer 5. After a period of use, the operator opens the clamping mechanism 7 and pulls the drawer 5 outward using the handle 500. The drawer 5 moves multiple dust collector bags 2 out of the receiving cavity 10, thereby cleaning the dust particles on the outer surface of the dust collector bags 2. After cleaning, the dust collector bags 2 are reinstalled and fixed. This dust removal equipment, used in conjunction with the grinding vehicle, achieves continuous and efficient dust removal while grinding, effectively solving the problems of dust pollution of the surrounding environment and impact on the health of workers.

[0037] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be included within the scope of protection of this utility model.
