Description
Technical Field

[0002] In recent years, with the rapid development of rail transit systems, people's travel has been greatly facilitated. When using railways or tracks, corresponding track accessories need to be configured to fasten the rails and the components under the machine, which are generally called railway fasteners. As fastening connectors for rails or rails, railway fasteners need to be maintained to ensure that they can effectively fasten and connect the tracks.
[0003] The maintenance of railway rail fasteners mainly includes fastener disassembly and assembly, fastener oiling and rust prevention, fastener rust removal and decontamination, and damaged fastener replacement. The disassembly and assembly of fasteners, especially screws or nuts, can keep the fasteners in a healthy state and effectively extend the service life of the fasteners. At present, the disassembly and assembly of fasteners mainly rely on manual operation or small-scale mechanical assistance. Although manual operation is flexible and can arrange work team personnel according to different maintenance volumes, and has strong applicability, manual disassembly and assembly of fasteners consumes a lot of labor.

[0059] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.
[0060] Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative work should fall within the scope of protection of this application.
[0061] like Figure 1 As shown, Figure 1 As shown, a railway fastener disassembly and assembly device comprises a vertical guide rod 1, a sliding assembly 2 and a disassembly and assembly assembly 3;
[0062] The vertical guide rod 1 is connected to the vehicle body;
[0063] The sliding assembly 2 is sleeved on the vertical guide rod 1 and can slide along the vertical guide rod 1;
[0064] like Figure 2 and Figure 3 As shown, the disassembly assembly 3 includes a housing 31, a power component 32, a swing arm 33, a transmission shaft 34, a transfer case 35, a movable sleeve 36, a lever sleeve 37, an escape wheel 38 and at least two output shafts 39;
[0065] The swing arm 33 is connected to the sliding assembly 2, and enables the disassembly assembly 3 to slide synchronously with the sliding assembly 2;
[0066] The power component 32 is arranged on the top of the housing 31, the two ends of the transmission shaft 34 are respectively connected to the power component 32 and the transfer case 35, and the two ends of the output shaft 39 are respectively connected to the transfer case 35 and the movable sleeve 36;
[0067] like Figure 4 As shown, the escape wheel 38 includes a dividing plate 381, a lip 382 and an open circular sleeve 383. The number of the open circular sleeve 383 is the same as that of the output shaft 39 and is arranged on the dividing plate 381. The lip 382 is opened at the lower part of the open circular sleeve 383 and cooperates with the buckle.
[0068] like Figure 5 As shown, the movable sleeve 36 is disposed in the open circular sleeve 383, the upper end of the movable sleeve 36 is connected to the lower end of the output shaft 39, and the lower end of the movable sleeve 36 is provided with an angular hole 361 that matches the fastener;
[0069] The two ends of the lever sleeve 37 are respectively connected to the transfer case 35 and the escape wheel 38 , and the escape wheel 38 can drive the transfer case 35 to rotate through the lever sleeve 37 .
[0070] The railway fastener disassembly and assembly device provided in this embodiment can be arranged on a railway work vehicle, and can also correspond to an additional separate fastener maintenance trolley, that is, the vehicle body connected to the vertical guide rod 1 refers to a work vehicle or trolley that provides the power required for the movement of the railway fastener disassembly and assembly device. It can be selected according to actual needs and work scenarios. Of course, other types of power supply equipment can also be selected, as long as it can drive the railway fastener disassembly and assembly device to move along the extension direction of the rail. In this embodiment, the work vehicle is used as an example of power supply.
[0071] Railway fasteners are generally composed of parts such as nuts, screws, washers, spring bars and baffles. The disassembly process of the fasteners is generally to remove the nut first, then remove the washers, spring bars and baffles on the screw in sequence, and then remove the screw. The most important and labor-intensive process is to loosen the nut from the screw, that is, to remove the nut. Therefore, this embodiment mainly takes the disassembly of the nut as an example to specifically explain the solution or operation, and the clockwise rotation of the nut is used as the direction of the loosening operation, and the counterclockwise rotation is used as the direction of the tightening operation.
[0072] In this embodiment, in order to ensure the reliability of individual selection of each movable sleeve 36 , each movable sleeve 36 is connected to a corresponding output shaft 39 , so the number of output shafts 39 and movable sleeves 36 remain consistent.
[0073] Of course, it is also possible to use only one output shaft 39, and then, based on judgment or instructions, specify the movable sleeve 36 that needs to be rotated within each time period, separate the output shaft 39 from other movable sleeves 36 that do not need to operate, and turn it to the movable sleeve 36 that needs to rotate. However, this method will cause additional operations or costs, and the judgment requires additional signal sending, receiving and processing, and manual sending of instructions requires manpower to judge whether the movable sleeve 36 needs to operate. Directly setting the same number of output shafts 39 as the movable sleeve 36 and keeping the two connected at all times is the most convenient and stable feasible solution.
[0074] In actual use, the work vehicle places the railway fastener disassembly and assembly device on the rails, and drives the railway fastener disassembly and assembly device to move along the extension direction of the rails. The center line of the escapement wheel 38 moves horizontally along the movement direction. When it hits the fastener, the open circular sleeve 383 of the escapement wheel 38 is stuck in the fastener. After the lip 382 contacts the fastener, the longitudinal movement is blocked, forcing the escapement wheel 38 to rotate around the fastener. The escapement wheel 38 drives the transfer case 35 to rotate through the lever sleeve 37.
[0075] When the transfer case 35 rotates, it sends a signal to the sliding assembly 2. After receiving the signal, the sliding assembly 2 slides downward along the vertical guide rod 1, causing the transfer case 35 to move downward synchronously until the corner hole 361 at the lower end of the movable sleeve 36 connected to the lower end of the transfer case 35 is locked with the nut of the fastener. At this time, the power component 32 starts to operate and outputs a clockwise rotational force through the transmission shaft 34, and the transfer case 35 transmits this force to the movable sleeve 36 through the output shaft 39, causing the movable sleeve 36 to rotate clockwise, and drives the nut on the fastener to rotate synchronously clockwise through the corner hole 361 locked with the nut, thereby loosening the nut.
[0076] When the escape wheel 38 rotates a certain angle, it will send a signal to the sliding assembly 2, triggering the upward movement of the sliding assembly 2. After receiving the signal, the sliding assembly 2 slides upward along the vertical guide rod 1, causing the transfer case 35 to move upward synchronously until the movable sleeve 36 connected to the lower end of the transfer case 35 is separated from the fastener, completing the operation step of loosening the nut from the fastener.
[0077] See also Fig.17 , with the movement direction of the vehicle body from left to right, in which only two views of the disassembled assembly in the initial state and the working state are fully identified, and the intermediate process is simplified and only used to describe the movement direction. The left side is the initial state of the disassembled assembly after being lowered and not contacting the fasteners, and the right side is the disassembled assembly has contacted the fasteners and entered the working state.
[0078] The above operation or steps are repeated for the next cycle to continue to loosen the next nut. The power component 32 is a motor in this embodiment, but other power drive components capable of outputting a rotational force can also be used, and the specific type can be selected according to actual needs.
[0079] Of course, the railway fastener disassembly and assembly device provided in this embodiment can also be used to tighten the nut on the fastener, that is, after completing other maintenance procedures, continue to tighten the nut again.
[0080] Specifically, the working vehicle drives the railway fastener disassembly and assembly device to move in the opposite direction of the extension of the rail, and the center line of the escapement wheel 38 moves horizontally along the movement direction. When it hits the fastener, the open circular sleeve 383 of the escapement wheel 38 is stuck in the fastener. After the lip 382 contacts the fastener, the longitudinal movement is blocked, forcing the escapement wheel 38 to rotate around the fastener, and the escapement wheel 38 drives the transfer case 35 to rotate through the lever sleeve 37.
[0081] When the transfer case 35 rotates, it sends a signal to the sliding assembly 2. After receiving the signal, the sliding assembly 2 slides downward along the vertical guide rod 1, causing the transfer case 35 to move downward synchronously until the corner hole 361 at the lower end of the movable sleeve 36 connected to the lower end of the transfer case 35 is locked with the nut. At this time, the power component 32 starts to operate and outputs a counterclockwise rotational force through the transmission shaft 34, and the transfer case 35 transmits this force to the movable sleeve 36 through the output shaft 39, causing the movable sleeve 36 to rotate counterclockwise, and drives the nut on the fastener to rotate synchronously counterclockwise through the corner hole 361 locked with the nut, thereby tightening the nut.
[0082] When the escape wheel 38 rotates a certain angle, it will send a signal to the sliding assembly 2, triggering the upward movement of the sliding assembly 2. After receiving the signal, the sliding assembly 2 slides upward along the vertical guide rod 1, causing the transfer case 35 to move upward synchronously until the movable sleeve 36 connected to the lower end of the transfer case 35 is separated from the fastener, completing the operation step of tightening the nut on the fastener.
[0083] Similarly, the railway fastener disassembly and assembly device provided in this embodiment can also perform the nut tightening operation alone, and the nut to be assembled on the screw of the fastener only needs to be placed in the corner hole 361 at the lower end of the movable sleeve 36 in advance, and a magnetic adsorption component can be provided in the corner hole 361 to prevent the nut in the corner hole 361 from falling off before reaching the corner hole 361. The specific type of the adsorption component is not limited, as long as it can meet the adsorption force of the nut and is less than the force between the nut and the screw after tightening.
[0084] Compared with the existing manual operation or small mechanical auxiliary operation, the railway fastener disassembly and assembly device provided in this embodiment does not need to detect or judge the fastener position with the help of detection equipment or manual vision when moving along the rail. The fastener position can be located only by the lip 382 matching the fastener, and after locating the fastener position, the lip 382 in contact with the fastener is used as a rotation point to rotate the escape wheel 38 corresponding to the lip 382, driving the transfer case 35 to rotate and triggering the sliding assembly 2 to slide, thereby causing the transfer case 35 to move downward, so that the corner hole 361 of the movable sleeve 36 connected to it is locked with the nut of the fastener, so as to automatically correspond the movable sleeve 36 to the position of the operation object. At this time, the power component 32 rotates counterclockwise, and transmits the rotational force to the movable sleeve 36 through the transmission shaft 34, the transfer case 35 and the output shaft 39 in turn, so that the movable sleeve 36 rotates synchronously, tightens the nut, and realizes the automatic operation of tightening the nut.
[0085] Therefore, the railway fastener disassembly and assembly device provided in this embodiment can realize the positioning of the fastener, the relative fixation of the rotating operating member, i.e., the movable sleeve 36, and the operating object, i.e., the nut, and the automated operation of loosening or tightening the nut, thereby saving the labor cost required for the corresponding process or operation and reducing safety risks.
[0086] In one implementation of this embodiment, Figure 6 As shown, a nut push rod 362 and a push rod spring 363 are provided in the movable sleeve 36. The nut push rod 362 is provided in the movable sleeve 36 and can slide in the movable sleeve 36. Both ends of the push rod spring 363 are in contact with the movable sleeve 36 and the nut push rod 362 respectively.
[0087] After the nut is loosened, the push rod spring 363 cooperates with the slidable nut push rod 362 to bring out the nut that is separated from the fastener screw after loosening, and push the nut out through the nut push rod 362. Specifically, after the nut is loosened, the movable sleeve 36 keeps rotating at a high speed and rises synchronously. After the nut is separated from the screw, it continues to rise for a certain stroke, leaving space for the nut to fall (or slide). In general, the nut will fall. For example, if the nut is stuck in the corner hole 316, the nut push rod 362 pushes the nut down under the action of the push rod spring 363. When the nut is tightened, the nut push rod 362 presses the nut or screw under the action of the push rod spring 363 to ensure the vertical direction during the tightening operation and avoid defective operation caused by the skewing of the nut or screw during rotation.
[0088] Furthermore, the corner hole 361 is a hexagonal hole 361 with a taper, a large hole and a small hole are arranged in the movable sleeve 36, one end of the nut push rod 362 is a large end matching with the large hole, and the other end of the nut push rod 362 is a small end matching with the small hole.
[0089] Since most railway fasteners use hexagonal nuts, in order to provide applicability and operability, the corner hole 361 is set to a matching hexagonal hole 361. At the same time, due to the presence of a certain taper, when the corner hole 361 and the nut are aligned, if there is a deviation, the movable sleeve 36 can be guided to cooperate with the nut. The large end and the small end at both ends of the nut push rod 362 and the large hole and the small hole in the movable sleeve 36 have no specific size restrictions in this embodiment. Large and small are only used as a comparison between the two. The large end is equivalent to the outer diameter of the nut and can contact the upper surface of the nut so that the nut can be pushed down, while the small end is used to ensure that the nut push rod is coaxial with the large end and plays a positioning role for the push rod spring 363.
[0090] Of course, since the nuts on the railway fasteners have various shapes, in addition to the common hexagonal nuts, there are also other shapes such as dodecagonal nuts, so the corner hole 361 can also be a twelve-sided hole or other polygonal hole.
[0091] Further, such as Fig.11As shown, a gasket 364 is provided on the small end of the nut push rod 362, and the nut push rod 362 is screwed into the movable sleeve 36 through the gasket 364, so that the nut push rod 362 can be better fixed. Of course, other fixing or connecting methods can also be selected according to actual needs, such as snap connection, which will not be repeated here.
[0092] In one implementation of this embodiment, Figure 7 As shown, it also includes an upper support beam 11 and a lower support beam 12 connected to the vehicle body. The vertical guide rod 1 is arranged between the upper support beam 11 and the lower support beam 12, which can enable the vertical guide rod 1 to obtain a better fixing effect and prevent unnecessary horizontal displacement of the sliding component 2 when sliding.
[0093] In one implementation of this embodiment, Figure 8 As shown, the sliding assembly 2 includes:
[0094] A sliding support 21 is sleeved on the vertical guide rod 1, and the sliding support 21 can slide along the vertical guide rod 1;
[0095] A pressure drive cylinder 22 connected to the sliding support 21, the pressure drive cylinder 22 is used to drive the sliding support 21 to slide;
[0096] like Fig. 9 As shown, the rotating shaft 23 is movably connected to the side of the sliding support 21, and the swing arm 33 is movably connected to the rotating shaft 23 through the rotating sleeve 24, and the swing arm 33 can swing around the rotating shaft 23.
[0097] In actual use, a guide rod hole matching the vertical guide rod 1 can be provided on the sliding support 21, and the vertical guide rod 1 passes through the guide rod hole and is connected to the vehicle body. One end of the pressure-driven cylinder 22 is connected to the sliding support 21, and the other end can be connected to the upper support or the lower support of the vehicle body. In the operation of loosening the nut, if it is connected to the upper support, the pressure-driven cylinder 22 pushes the sliding support 21 to move vertically downward, and if it is connected to the lower support, the pressure-driven cylinder 22 pulls the sliding support 21 to move vertically downward. In addition, the pressure-driven cylinder 22 can select a hydraulic cylinder or a gas cylinder according to actual needs or the structure of the vehicle body. In addition, the swing arm 33 can swing around the rotating shaft 23 within a predetermined angle to meet all possible swing ranges of the disassembly assembly component 3 during the nut disassembly operation, avoiding stress damage caused by hard fixation. At the same time, since the vehicle advances and the rotation of the escape wheel 38 form a composite motion, the swing arm 33 is used to generate a degree of freedom of rotation. In this embodiment, the range of this predetermined angle is plus or minus 20°.
[0098] Of course, in addition to the above settings, the swing arm 33 can also swing with the vertical guide rod 1 as its rotation center axis, that is, the swing arm 33 is movably connected to the vertical guide rod 1 through the rotating sleeve 24, and the swing arm 33 can swing around the vertical guide rod 1, which can also achieve a similar effect.
[0099] In one implementation of this embodiment, Fig.10 As shown, the transfer case 35 includes an input interface 351 arranged at one end and an output interface 352 arranged at the other end. The transmission shaft 34 is connected to the transfer case 35 through the input interface 351, and the output shaft 39 is connected to the transfer case 35 through the output interface 352. The number of the output interfaces 352 is consistent with that of the output shafts 39.
[0100] In actual use, the output shaft 39 and the output interface 352 can be detachably connected for easy replacement or maintenance, or can be fixedly installed. Similarly, the transmission shaft 34 and the input interface 351 can also be detachably connected. The specific connection method will not be repeated here.
[0101] Furthermore, the number of the output shaft 39 and the number of the output interfaces 352 are both three, and the three output interfaces 352 surround the periphery of the input interface 351 and are symmetrically distributed.
[0102] The symmetrical distribution described here, in this embodiment, is that if the center points of the three output interfaces 352 are connected to each other in pairs, the three connecting lines connected end to end can form an equilateral triangle. This design can effectively improve the structural stability of the transfer case 35 itself when the output shaft 39 rotates, and enhance the position fixity of the movable sleeve 36 when it rotates.
[0103] In one implementation of this embodiment, Fig.11 As shown, the disassembly assembly also includes a connecting spring sleeve 4 arranged next to the lever sleeve 37, and the connecting spring sleeve 4 includes a first sleeve 41, a guide post 42, a guide post spring 43 and a locking plate 44;
[0104] The upper end of the first sleeve 41 is connected to the lower end of the transfer case 35, and the locking plate 44 is sleeved on the first sleeve 41;
[0105] The guide post 42 is disposed in the first sleeve 41, the lower end of the guide post 42 is connected to the upper end of the escape wheel 38, and a limiting member 45 matching with the locking plate 44 is disposed in the middle of the guide post 42;
[0106] One end of the guide post spring 43 contacts the inner top of the first sleeve 41 , and the other end contacts the upper top of the guide post 42 .
[0107] The locking plate 44 is movably mounted on the first sleeve 41 while clamping the limiter 45 , restricting the guide post 42 in the first sleeve 41 and allowing the guide post 42 to slide within a certain range in the first sleeve 41 , while the guide post spring 43 resets the guide post 42 .
[0108] Due to the effect of the connecting spring sleeve, the lower bottom surface of the escape wheel 38 and the upper plane of the buckle can maintain a relatively fixed vertical distance, thereby preventing the escape wheel 38 from directly contacting the buckle during operation and interfering with the vertical movement of the sliding assembly 2 or the rotational movement of the movable sleeve 36.
[0109] Among them, the limiting member 45 can be a raised step or other components with a planar size difference with the locking plate 44. In addition, in addition to the matching method of the locking plate 44 and the limiting member 45, the limiting between the guide column 42 and the guide sleeve can also be achieved by using a pin shaft and a waist-shaped hole.
[0110] In one implementation of this embodiment, Fig.12 As shown, the disassembly and assembly component also includes an inner shell 311 and a sensor 312. The inner shell 311 is connected to the swing arm 33 and the outer shell 31. The lower end of the inner shell 311 is connected to the transfer case 35. The sensor 312 is arranged on the inner wall of the outer shell 31 and is used to control the sliding direction of the sliding component 2.
[0111] The inner shell 311 is connected to the swing arm 33 and the outer shell 31 , and the transfer case 35 connected to the lower end thereof can drive the inner shell 311 to rotate in the swing arm 33 , thereby triggering the sensor 312 to control the sliding assembly 2 to slide.
[0112] Further, such as Fig.12 As shown, a cam flange 313 is installed on the upper end of the inner shell 311, and the inner shell 311 is connected to the swing arm 33 and the outer shell 31 through a bearing. The sensor 312 is arranged on the inner wall of the outer shell 31 and corresponds to the cam flange 313, so that the inner shell 311 rotates in the swing arm 33, touches the movement of the cam flange 313, and then triggers the sensor 312.
[0113] In actual use, other movable parts can be used to replace the cam flange 313 according to the specific shapes or structures of the inner shell 311 and the outer shell 31. The specific types and settings will not be repeated here.
[0114] In one implementation of this embodiment, Fig.13 As shown, the lever sleeve 37 includes a second sleeve 371 and a lever 372. The upper end of the second sleeve 371 is connected to the transfer case 35. The lever 372 is arranged in the second sleeve 371 and the lower end is connected to the escapement wheel 38. The escapement wheel 38 drives the transfer case 35 to rotate through the lever 372.
[0115] In this embodiment, a protrusion extending in the horizontal direction is provided at the upper end of the second sleeve 371, and the transfer case 35 is connected to the second sleeve 371 through the protrusion. Since the protrusion has a larger contact area than the sleeve of the second sleeve 371, the stability of the lever 372 in driving the transfer case 35 to rotate can be increased. Of course, a clamping groove matching the protrusion can also be additionally provided on the transfer case 35, that is, a detachable connection is adopted, which facilitates the disassembly or maintenance between the lever sleeve 37 and the transfer case 35 while maintaining the contact area.
[0116] In one implementation of this embodiment, Fig.14 As shown, the escape wheel 38 further includes a stop post 384 disposed on the upper portion of the open circular sleeve 383 .
[0117] By setting the stop post 384, when the railway fastener disassembly and assembly device moves along the track and does not contact the fastener, the stop post 384 contacts the rail head, so that the escape wheel 38 maintains a fixed lateral distance from the track, reducing the probability of the escape wheel 38 deviating from the predetermined direction before contacting the fastener.
[0118] Furthermore, there are two stop posts 384 , which are respectively disposed above the opening side edge of each open circular sleeve 383 .
[0119] There are two stop posts 384, and they are located on the upward extension lines of the two sides of the lower opening of the open circular sleeve 383, so that when the escape wheel 38 rotates, one of the stop posts 384 that is not in contact with the track can be used as an auxiliary rotation fulcrum to enhance the stability during rotation.
[0120] Of course, the stop column 384 is located above the opening side of the open circular sleeve 383, but the specific position can be any corresponding position. The above-mentioned upward extension line of the side is only one of the settings. This application does not make other examples or limitations on the specific position of the stop column 384.
[0121] In one implementation of this embodiment, it also includes a transposition component connected to the vertical guide rod 1, the transposition component includes a transverse guide rail and a guide rod slider, the top of the vertical guide rod 1 is connected to the guide rod slider, and the guide rod slider can slide along the transverse guide rail.
[0122] In the aforementioned implementation manner of this embodiment, the disassembly operation is aimed at the fasteners of a single track or one side of the track, and the track is usually composed of two iron rails or steel rails, and railway fasteners are provided on both sides. Therefore, by setting a transposition component, when the railway fastener disassembly and assembly device completes the operation on the fasteners on one side, the vertical guide rod 1 can be allowed to slide along the transverse guide rail through the guide rod slider, and then the whole is transposed to the other side, and the same operation is continued on the fasteners on the other side to complete the overall maintenance of the fasteners on both sides of the track.
[0123] Furthermore, limit blocks and a pushing pressure cylinder are respectively provided at both ends of the transverse guide rail, and the pushing pressure cylinder can push the guide rod slider to slide.
[0124] By setting a limit block, the sliding position and distance of the vertical guide rod 1 can be effectively restricted to prevent it from sliding out of the transverse guide rail during the overall replacement. In addition, the guide rod slider is pushed by a pushing pressure cylinder, thereby driving the vertical guide rod 1 to slide. In this embodiment, the pushing pressure cylinder can be a hydraulic cylinder or a pneumatic cylinder.
[0125] In one implementation of this embodiment, Fig.15 As shown, the number of the vertical guide rods 1 and the number of the disassembly and assembly components 3 are both two, and the vertical guide rods 1 and the disassembly and assembly components 3 are symmetrically arranged along the extension direction of the rails.
[0126] Similar to the previous embodiment, in order to be able to disassemble and assemble the fasteners on both sides of a single track, the vertical guide rods 1 and the disassembly and assembly components 3 are set in number, which can be regarded as two groups of vertical guide rods 1 and two groups of disassembly and assembly components 3, and one group is set on each side of the track, but the sliding component 2 can share one group, or the number of the rotating sleeve 24 and the rotating shaft 23 connected to the swing arm 33 in the sliding component 2 is two, and the number of the sliding support 21 and the pressure drive cylinder 22 is still one.
[0127] If configured as above, the fasteners on both sides of a single track can be disassembled and assembled at the same time.
[0128] Further, such as Fig.16 As shown, this embodiment, that is, the number of vertical guide rods 1 and disassembly and assembly components 3 is four, and every two vertical guide rods 1 and every two disassembly and assembly components 3 are symmetrically arranged along the extension direction of a single rail, can simultaneously perform disassembly and assembly operations on the fasteners on both sides of the two rails.
[0129] It should be noted that in order to further improve the automation effect, on the basis of the above-mentioned implementation mode, it also includes a control system, which is used to control the opening and closing of the power component 32, the pressure drive cylinder 22 and the push pressure cylinder. It can be connected to the sensor 312 to obtain a control signal, or it can directly obtain operating instructions from the operator. The specific settings will not be repeated here.
