Description

Technical Field

[0001] The invention relates to the technical field of rail engineering machinery, in particular to a fireproof and dustproof device for a grinding trolley used for a rail grinding trolley. Background Art

[0002] During the operation of the train, the rails are prone to fat edges, wave wear, rail surface fish scales and other diseases due to long-term harsh working environment, which seriously affects driving safety. The rail grinding car can improve the smoothness of the rails by removing the uneven factors on the surface of the rails, slow down the development of surface defects of the rails, and extend the service life of the rails. The grinding car is the actuator of the grinding operation and a key component of the rail grinding car. During the operation of the rail grinding car, on the one hand, the sparks and high-temperature iron filings generated during the rail grinding process are easy to damage the infrastructure around the rails or ignite the materials around the track to cause a fire. On the other hand, the dust generated by grinding can cause harm to the operators, environmental pollution, and equipment damage. The fire and dust prevention device can fully cover the grinding device to form a relatively closed environment, which is conducive to the dust collection device to collect dust through the dust collection channel, and reduce the adverse effects of the sparks and high-temperature iron filings generated during the operation of the rail grinding car on the equipment and the surrounding environment, effectively improving the working environment. Therefore, as one of the core components of the grinding trolley, the fire and dust prevention device plays an important role in eliminating safety hazards in the operation of the rail grinding trolley.

[0003] In the prior art, the following technical solutions are mainly related to the present invention:

[0004] Prior art 1 is a Chinese invention application filed on April 22, 2014, published on July 9, 2014, and with publication number CN103911925A. The application discloses a rail grinding vehicle frame, including a longitudinal beam, end beams are transversely arranged at both ends of the longitudinal beam, a transverse beam is transversely arranged in the middle of the longitudinal beam, end plates are fixed to the outer sides of the two end beams, side plates are fixed to the ends of the end beam and the transverse beam, cover plates are fixed to the upper parts of the longitudinal beam, the end beam and the transverse beam, and the lower parts of the end plate and the side plate are connected to fire curtains. The frame is provided with a limit groove, a dust cover, a locking device, etc. The application is applicable to various rail grinding vehicles, and is used to correct various rail defects caused by vehicles running on rails, such as wavy wear of rails, wheel-rail scratches, correct the inclination and deformation of inner and outer rails, and trim the wheel-rail contact surface, and perform preventive maintenance of line rails. The rail grinding vehicle frame of the application has a simple structure, high cost performance, and low maintenance cost.

[0005] However, the fire and dust prevention device for rail grinding trolley in the prior art still has the following technical defects:

[0006] (1) The side and end faces of the grinding cart in the prior art both adopt a door-type rigid connection structure, which limits the use of the side space. When the internal structure of the grinding cart needs to be maintained, the side baffle cannot be directly removed, which blocks the side space and is inconvenient for maintenance personnel to perform maintenance operations;

[0007] (2) The fire and dust prevention device of the rail grinding trolley in the prior art adopts an integral frame closed structure, and the trolleys are all equipped with rectangular cross beams and end beams. Such a structure makes it very difficult to maintain the grinding trolleys. At the same time, there is no shielding under the longitudinal beam of the grinding trolley frame, and the grinding sparks on one side can easily splash onto the grinding motor on the other side, which poses a serious hidden danger to the safety of the grinding trolley operation. Summary of the invention

[0008] In view of this, the purpose of the present invention is to provide a fire and dust prevention device for a rail grinding trolley to solve the technical problems that the existing fire and dust prevention device for a rail grinding trolley adopts a rigid connection structure, is inconvenient for space utilization, is difficult to repair and maintain, and has potential safety hazards.

[0046] As attached Figure 1 To Attachment Fig.12 As shown, a specific embodiment of the fire and dust prevention device for the rail grinding trolley of the present invention is given, and the present invention is further described below in conjunction with the drawings and specific embodiments.

[0047] As attached Figure 1 To Attachment Figure 5 As shown in FIG. 1 , an embodiment of a fireproof and dustproof device for a rail grinding trolley is shown. The fireproof and dustproof device 100 specifically includes: a middle baffle 2, a cover plate 3, a door 5, a dust collecting curtain 7, an end baffle 11 and a fireproof curtain. The cover plate 3 is arranged on the dust collecting curtain 7 along the working direction of the grinding trolley 300 (as shown in FIG. 1 ). Figure 1 and attached Fig.10 The left and right sides of the frame 400 (in the direction shown by L in the figure) are connected and installed on the frame 400 of the grinding trolley 300 by bolt connection. One side of the dust collecting curtain 7 is connected to the bottom of the body of the grinding trolley 200, and the other opposite side is connected to the cover plate 3. The car door 5 is arranged on the left and right sides of the grinding trolley 300 along the working direction, and is hinged to the cover plate 3. The middle baffle 2 is suspended and connected to the bottom of the frame 400, and the end baffles 11 are arranged at the front and rear ends of the grinding trolley 300 along the working direction, and are installed on the frame 400. The lower parts of the end baffles 2 and the car door 5 are connected with fire curtains. The fireproof and dustproof device of the rail grinding trolley described in the specific embodiment of the present invention has the functions of preventing the sparks of grinding from splashing to cause fire hazards, and facilitating the collection of grinding dust to reduce environmental pollution.

[0048] The dust collecting curtain 7 has an opening at the top and is connected to the bottom of the body of the grinding vehicle 200 through the longitudinal beam 1, so as to be connected to the dust collecting channel and collect the dust generated during the grinding process into the dust collecting device through the dust collecting channel. Fig.12 As shown, the longitudinal beam 1 is arranged on the top of the dust collecting curtain 7 and installed below the grinding vehicle 200. The longitudinal beam 1 further adopts a hollow beam structure with upper and lower ends opened, as shown in the attached Figure 1 and attached Figure 8 The end baffle 11 is further provided with a mounting seat 10, and a locking seat 13 is provided at a position corresponding to the mounting seat 10 on the door 5. Figure 6As shown. When the door 5 is closed, the locking of the door 5 is achieved by inserting the locking pin 9 into the mounting seat 10 and the locking seat 13. The door 5 is connected to the cover plate 3 by a hinge 4, so that the door 5 can rotate around the hinge 4. A handle 23 is provided on the door 5, so that the door 5 can be directly opened and closed by the handle 23, and the door 5 can be opened and closed at a large angle. When the door 5 is closed, the locking pin 9 is used to lock the door 5. The fireproof and dustproof device 100 also includes a door buffer mechanism 8, one end of which is connected to the mounting seat 10, and the other end is connected to the door 5. The door buffer mechanism 8 can control the large-angle opening and closing of the door 5 to facilitate maintenance. The buffering effect of the door buffer mechanism 8 makes the door 5 more stable when opened and closed. The door buffer mechanism 8 can adopt a structure in the form of an oil cylinder, an air cylinder, an electric cylinder, a spring, etc. During the operation of the grinding cart 200, when it is necessary to inspect, repair and maintain the internal structure of the grinding cart 300, such as the grinding unit 500, the door 5 is opened and there is no other structure blocking the side, so the internal structure of the grinding cart 300 can be directly operated, making the repair and maintenance of the grinding cart 300 more convenient and quick.

[0049] As attached Figure 6 As shown, the vehicle door 5 is connected to the cover plate 3 through a hinge 4, and the hinge 4 further includes a hinge mounting seat 14, a hinge head 15 and a rotating shaft 16. The hinge mounting seat 14 is arranged on the bottom side of the cover plate 3. One end of the hinge head 15 is fixed to the rotating shaft 16, and the other end is fixed to the top side of the vehicle door 5. When the vehicle door 5 is opened and closed, the hinge head 15 can rotate around the hinge mounting seat 14, so as to realize the large-angle opening and closing of the vehicle door 5. In addition to the hinge connection method described in the specific embodiment of the present invention, the vehicle door 5 and the cover plate 3 can also be opened and closed at a large angle by adopting other movable connection methods.

[0050] The fire curtain further includes a side fire curtain 6 and an end fire curtain 12, the side fire curtain 6 is suspended at the lower part of the door 5, and the end fire curtain 12 is suspended at the lower part of the end baffle 11. The cover plate 3, the door 5, the dust collecting curtain 7, the end baffle 11, the side fire curtain 6 and the end fire curtain 12 form a local sealing structure of the grinding trolley 300, so that the grinding dust generated during the operation can be collected into the dust collecting device through the dust collecting channel. The fireproof and dustproof device of the rail grinding trolley described in the specific embodiment of the present invention makes the structure of the grinding trolley 300 more sealed through the plate structure of the end and the side, as well as the dust collecting curtain 7 and the fire curtain, and the grinding dust generated during the operation can be collected into the dust collecting device through the dust collecting channel, thereby reducing the harm of dust to the operators, the pollution to the environment, and the damage to the equipment.

[0051] Small holes are opened at the corresponding positions of the fire curtain and the plate structure (including the car door 5 and the end baffle 11) so that they can be assembled and connected through the perforated pin 17, and then the circular ring pin 19 and the cotter pin (not shown in the figure) are respectively inserted into the holes at both ends of the perforated pin 17 to fix the fire curtain. The use of the pin structure makes the disassembly and assembly of the fire curtain very flexible and convenient, so it can effectively save the replacement time when the fire curtain is replaced, and realize the rapid disassembly and assembly of the fire curtain. The side fire curtain 6 and the end fire curtain 12 made of flexible material are respectively installed at the bottom of the car door 5 and the end baffle 11, which can adapt to different ballast heights and effectively prevent the sparks (high-temperature iron filings) generated when the grinding wheel grinds the rails from splashing, damaging the facilities beside the rails or igniting the materials around the track to cause a fire.

[0052] As attached Figure 5 As shown, the fire and dust prevention device 100 also includes a middle baffle 2, which includes a plurality of independent unit baffles. Each unit baffle is connected to form a whole through a flexible connection and then suspended and installed on the frame 400 of the grinding trolley 300 through a quick connection ring 22. Fig. 9 and attached Fig.11 As shown, the grinding sparks on one side are prevented from flying onto the grinding motor 600 on the other side, and the grinding unit 500 is prevented from interfering with the middle baffle plate 2 when it is deflected. The middle baffle plate 2 is composed of multiple groups of independent small unit baffle plates, each group of unit baffle plates is connected by a quick connection ring 22 and then suspended and installed on the frame 400 of the grinding trolley 300. Its main function is to prevent the grinding sparks on one side from flying onto the grinding motor 600 on the other side. The suspension connection structure of multiple groups of unit baffle plates has a certain deflection. When the grinding units 500 on both sides of the grinding trolley 300 are deflected to a certain angle for grinding, it can effectively prevent the grinding units 500 from interfering with the middle baffle plate 2 when they are deflected, thereby damaging the grinding units 500.

[0053] As attached Figure 1 and attached Figure 3 As shown, the end baffle 11 further includes two groups of large and small sub-baffles, each of which is arranged in the horizontal direction. The upper part of the relatively large sub-baffle is connected to the frame 400 of the grinding trolley 300 by bolts, and the relatively small sub-baffle is connected to the frame 400 by bolts. Fig.10 and attached Fig.11 shown.

[0054] As attached Figure 8As shown, the dust collecting curtain 7 is further made of flexible material, and the dust collecting curtain 7 is connected to the longitudinal beam 1 through a circular ring pin 19. The circular ring pin 19 includes a circular ring 21 connected to the dust collecting curtain 7, and an open hole cylinder 20 connected to the circular ring 21 at one end and connected to the longitudinal beam 1 at the other end. Since the dust collecting curtain 7 on the top of the fireproof and dustproof device 100 is made of soft material, when the grinding trolley 300 is lifted or lowered, the dust collecting curtain 7 can be flexibly folded, so as not to have any influence on the lifting function of the frame 400 of the grinding trolley 300.

[0055] As attached Figure 7 As shown, the vehicle door 5 and the side fire curtain 6 are further connected by a pin with a hole 17 and a circular ring pin 19, one end of the pin with a hole 17 is inserted into the mounting holes of the vehicle door 5 and the side fire curtain 6, and the circular ring pin 19 is inserted into the other end of the pin with a hole 17 with a through hole. The other end of the pin with a hole 17 can be designed with a thread, and the vehicle door 5 and the side fire curtain 6 are fixedly connected by a fixing nut 18. The other end of the pin with a hole 17 can also be designed with a through hole, and the vehicle door 5 and the side fire curtain 6 are fixedly connected by inserting a split pin.

[0056] As a preferred specific embodiment of the present invention, the cover plate 3, the end baffle 11, the door 5, and the middle baffle 2 are further made of aluminum material, which effectively realizes the lightweight design of the fireproof and dustproof device 100. In order to ensure that the structural rigidity meets the requirements of actual engineering applications, the reinforced structures such as the longitudinal beam 1 and the door 5 are all made of steel structure. The side fire curtain 6 and the end fire curtain 12 are further made of special fire curtains made of high chromium and high silicon materials. Compared with traditional fireproof cloth materials, this special fire curtain has higher heat resistance and a longer service life.
