Description

Technical Field

[0001] The present specification relates to the technical field of railway track accessories and machines for laying various railways, and in particular to a railway track spring bar gap detection device and railway track equipment. Background Art

[0002] In the process of laying rails, it is usually necessary to fix the rails on the sleepers through rail fasteners, and the rail fasteners cooperate with the sleepers to ensure the stability of the rails. Obviously, the installation effect of the rail fasteners directly affects the stability of the rails.

[0003] Railway fasteners are mainly composed of spring bars, fastener nuts, baffle seats, gauge baffles and other structures. During the installation of railway fasteners, it is necessary to tighten and loosen the fastener nuts, adjust the positional relationship and torque between the spring bars and the gauge baffles, and complete the installation. The "Technical Manual for the Installation of Passenger Dedicated Line Railway Fastener Systems" stipulates that "the standard for judging whether the spring bar is installed in place is that the front end lower jaw of the middle of the spring bar just touches the rail, and the gap between the two is not more than 0.5mm." Article 3.5.3 of the "Railway Line Repair Rules" stipulates that "the front end lower jaw of the middle of the spring bar of the spring bar fastener should be against the gauge baffle (the gap is not more than 1mm) or the torque should be maintained at 80-150Nm.

[0004] In the prior art, whether the installation of the spring bar meets the requirements is often determined by measuring the torque between the front end lower jaw of the middle part of the spring bar and the gauge baffle, or by manually measuring the distance between the front end lower jaw of the middle part of the spring bar and the gauge baffle with a ruler. Summary of the invention

[0005] The present specification provides a railway track spring bar gap detection device and railway track equipment to at least partially solve the above-mentioned problems existing in the prior art.

[0078] Preferably, the elastic bar 63 is an ω-shaped elastic bar 63 .

[0079] Those skilled in the art can understand that the middle lower jaw 631 of the elastic bar 63 is the downward bending part of the middle part of the elastic bar 63 .

[0088] Preferably, the shape of the fixing member 5 is adapted to the steel rail 61 , and can be detachably connected to the steel rail 61 , thereby fixing the shading bracket 1 to both sides of the steel rail 61 .

[0089] Preferably, the shapes of the first bracket 11 and / or the second bracket 12 and / or the top shading member 13 and / or the fixing member 5 are adapted to the rail 61, so that the fixing member 5 is connected to the rail 61, and when the gap detection device 0 of the railway track spring bar is connected to the fixing member 5, the bottom end of the first bracket 11 is in close contact with the rail 61, and the bottom end of the second bracket 12 is in close contact with the rule block.

[0090] Figure 8 A schematic diagram of a portion of the structure of a railway track equipment provided in one embodiment of this specification. Figure 8 As shown, the device body 7 is respectively connected to the gap detection devices 0 of two railway track spring bars, the fixing member 5 is connected to the rail 61, the bottom end of the first bracket 11 is in close contact with the rail 61, and the bottom end of the second bracket 12 is in close contact with the rule block.

[0091] The above embodiment provides a railway track spring bar gap detection device 0, which includes a light shielding bracket 1, a photosensitive element 2, a light emitting element 3 and a controller 4. The first bracket 11 and the second bracket 12 in the light shielding bracket 1 are arranged opposite to each other, and a top light shielding member 13 is arranged on the top. The photosensitive element 2 and the light emitting element 3 are fixed to the opposite sides of the first bracket 11 and the second bracket 12, respectively, and the space between them can accommodate the middle jaw 631 of the spring bar 63. When the bottom ends of the first bracket 11 and the second bracket 12 are respectively in close contact with the gauge baffle 62 and the rail 61, and the middle jaw 631 is accommodated in the middle, the light 31 emitted by the light emitting element 3 can pass through the gap 66 between the middle jaw 631 and the gauge baffle 62 and irradiate the photosensitive element 2. The photosensitive element 2 can determine and send the photosensitive data to the controller 4 based on the sensed light 31. The controller 4 can determine the gap 66 detection result based on the photosensitive data.

[0092] According to the above embodiment, it can be seen that the device can measure the gap 66 between the spring bar 63 and the gauge baffle 62 through the light-emitting element 3 and the photosensitive element 2, so as to determine whether the installation of the spring bar 63 meets the standard, and this method will not be affected by the processing accuracy of components such as the spring bar 63 and the gauge baffle 62, and has high accuracy and reliability.

[0093] Preferably, the photosensitive coupling element includes a plurality of photosensitive units.

[0094] For example, the photosensitive element 2 is a CCD device, and the photosensitive element 2 includes a plurality of photosensitive units (field effect transistor capacitors or photosensitive diodes), and each photosensitive unit can convert a received light signal into an electrical signal.

[0095] Preferably, the photosensitive data includes light intensity data corresponding to each photosensitive unit, and the light intensity data is the intensity of the light 31 received by any photosensitive unit.

[0096] Preferably, each photosensitive unit of the photosensitive element 2 can output corresponding light intensity data based on the intensity of the sensed light 31 .

[0097] Continuing with the above example, when the photosensitive element 2 is a CCD device, and each photosensitive unit constituting the CCD outputs an 8-bit binary electrical signal, each photosensitive unit can output light intensity data within a range of 0-265 based on the sensed light 31.

[0098] It is understood by those skilled in the art that the photosensitive units constituting different photosensitive elements 2 can sense the light 31 with different precision or output precision. For example, the output of some photosensitive units is an 8-bit binary electrical signal, and the output of some photosensitive units is a 16-bit binary electrical signal. Therefore, different photosensitive elements 2 have different precisions in sensing light intensity, and different output precisions, and the corresponding light intensity data has different precisions. Therefore, in this specification, there is no limitation on the structure of the photosensitive element 2 and the precision of the output light intensity data.

[0099] It is understood by those skilled in the art that when the middle lower jaw 631 of the elastic bar 63 is between the first bracket 11 and the second bracket 12, the light 31 emitted by the light emitting element 3 can pass through the gap 66 between the middle lower jaw 631 and the gauge baffle 62 and irradiate the photosensitive element 2. The larger the gap 66, the more light 31 will pass through the gap 66, and more photosensitive units in the photosensitive element 2 will sense the light 31, and the light intensity of each photosensitive unit will be greater, and the light intensity data output by each photosensitive unit will be greater.

[0100] Therefore, in one or more embodiments of the present specification, the controller 4 may determine the detection result of the gap 66 based on the light intensity data corresponding to each photosensitive unit in the photosensitive data.

[0101] Preferably, when the controller 4 runs the computer program, it can accumulate the light intensity data of each photosensitive unit to determine the photosensitivity result.

[0102] Preferably, the controller 4 stores a first threshold and a second threshold.

[0103] Preferably, when the controller 4 runs the computer program, it can also determine the numerical values ​​of the photosensitivity result and the first threshold value and the second threshold value.

[0104] Preferably, the controller 4 is further configured to determine that the detection result of the gap 66 is to be tightened when it is determined that the photosensitivity result is greater than the first threshold.

[0105] Preferably, the controller 4 is further configured to determine that the detection result of the gap 66 is installed in place when it is determined that the photosensitivity result is greater than or equal to the second threshold value and less than or equal to the first threshold value.

[0106] Preferably, the controller 4 is further configured to determine that the detection result of the gap 66 is to be loosened when it is determined that the photosensitivity result is less than the second threshold value.

[0107] Preferably, the photosensitivity result is equal to the first threshold value, indicating that the width of the gap 66 between the middle lower jaw 631 of the elastic bar 63 and the track gauge baffle 62 is 0.5 mm.

[0108] Preferably, the photosensitivity result is equal to the first threshold value, indicating that the width of the gap 66 between the middle lower jaw 631 of the elastic bar 63 and the track gauge baffle 62 is 1 mm.

[0109] Preferably, the photosensitivity result is equal to the second threshold value, indicating that the width of the gap 66 between the middle lower jaw 631 of the elastic bar 63 and the gauge baffle 62 is 0.1 mm.

[0110] Preferably, the photosensitivity result is equal to the second threshold value, indicating that the width of the gap 66 between the middle lower jaw 631 of the spring bar 63 and the track gauge baffle 62 is 0 mm.

[0111] Those skilled in the art can understand that the first threshold and the second threshold are both preset values ​​and can be modified in response to user operations. Therefore, when the photosensitivity result is equal to the first threshold or the second threshold, the width of the gap 66 between the middle lower jaw 631 of the elastic bar 63 and the track gauge baffle 62 can also be other values, and this specification does not limit this.

[0112] Those skilled in the art can also understand that there are many types of parts such as spring bars 63 and gauge blocks, and they are of different shapes, so when spring bars 63 and gauge blocks of different types are installed, even if the width of the gap 66 between the middle jaw 631 of the spring bars 63 and the gauge block 62 is the same, the light 31 transmitted is different, and the photosensitivity results determined by the controller 4 are also different. Therefore, when using the device, the user can set the corresponding first threshold and second threshold for parts such as spring bars 63 and gauge blocks of different types.

[0113] Preferably, the controller 4 can pre-store the first threshold value and the second threshold value corresponding to various types of spring bars 63, gauge blocks and other components.

[0114] Preferably, the controller 4 can select the first threshold and the second threshold of the corresponding model in response to the user's operation, so as to determine the detection result of the gap 66 based on the selected first threshold and the second threshold.

[0115] It is understood by those skilled in the art that if the first bracket 11 is not in close contact with the steel rail 61, ambient light can penetrate through the gap between the first bracket 11 and the steel rail 61, affecting the accuracy of the device. Correspondingly, if the second bracket 12 is not in close contact with the track gauge block, the accuracy of the device will also be affected. Therefore, in one or more preferred embodiments provided in this specification, the bottom ends of the first bracket 11 and the second bracket 12 are both provided with contact members.

[0116] Preferably, the contact piece is a micro switch, a push button switch, etc.

[0117] Preferably, the contact piece is a micro switch.

[0118] Preferably, the contactor is electrically connected to the controller 4 , and can send a contact signal and a disconnection signal to the controller 4 when contacting and stopping contacting the rail 61 or the gauge baffle 62 .

[0119] Preferably, the controller 4 is electrically connected to the light emitting element 3 and can send a switch instruction to the light emitting element 3 .

[0120] Preferably, the controller 4 is further configured to instruct the light emitting element 3 to emit light 31 through the switch instruction after determining that the contact signals emitted by the two contact members are received.

[0121] Preferably, the controller 4 is further configured to instruct the light emitting element 3 to stop emitting the light 31 through the switch instruction after determining that a disconnection signal sent by any contact is received.

[0122] It should be noted that the controller 4 will instruct the light emitting element 3 to emit light 31 through the switch command only after receiving the contact signal sent by the two contact members configured at the bottom of the first bracket 11 and the second bracket 12. However, it only needs to receive the disconnection signal sent by any one of the contact members to instruct the light emitting element 3 to stop emitting light 31 through the switch command.

[0123] Preferably, the contact is electrically connected to the controller 4 and can be turned on when it contacts the rail 61 or the gauge baffle 62 .

[0124] Preferably, the controller 4 is further configured to instruct the light emitting element 3 to emit light 31 through the switch instruction after determining that the two contacts are both turned on.

[0125] Preferably, the controller 4 is further configured to instruct the light emitting element 3 to stop emitting the light 31 through the switch instruction after determining that any one of the contacts is disconnected.

[0126] Preferably, the controller 4 comprises a power supply.

[0127] Preferably, the controller 4 is also electrically connected to the light emitting element 3 and the photosensitive element 2 respectively, and is also used to provide electrical energy to the light emitting element 3 and the photosensitive element 2 respectively.

[0146] Fig.10 The schematic diagram of the structure of the railway track equipment provided in one embodiment of the present specification. Fig.10 As shown, the equipment body 7 is connected to the railway track spring bar gap detection device 0.

[0147] It is understood by those skilled in the art that, in the process of fixing the rail 61 by means of the rail fasteners, two rail fasteners are usually respectively arranged on both sides of the rail 61, so as to fix the rail 61 at a certain position. Therefore, in one or more preferred embodiments provided in this specification, the rail track equipment includes two rail track spring bar gap detection devices 0, which detect the gaps 66 of the spring bars 63 distributed on both sides of the rail 61 at one time.

[0157] Fig.11 The following is a schematic diagram of a partial structure of a railway fastener provided in accordance with an embodiment of the present specification. Fig.11 As shown, the fastener nut 64 is sleeved on the outer surface of the spiral spike 65, and the lower side of the fastener nut 64 contacts the spring bar 63. The lower side 632 of the spring bar 63 is in close contact with the gauge baffle 62, but there is a gap 66 between the middle lower jaw 631 of the spring bar 63 and the gauge baffle 62. When the fastener nut 64 is tightened downward, it can compress the spring bar 63, causing the spring bar 63 to move and deform, so that the middle lower jaw 631 of the spring bar 63 is close to the gauge baffle 62, and the gap 66 is reduced. When the fastener nut 64 is loosened upward, the spring bar 63 can be deformed based on its own elastic force, so that the middle lower jaw 631 of the spring bar 63 is away from the gauge baffle 62, and the gap 66 is enlarged.

[0158] Preferably, the controller 4 can also send a pre-tightening instruction to the pre-tightening wrench, instructing the pre-tightening wrench to tighten or loosen the fastener nut 64 .

[0159] Preferably, the controller 4 can also send a stop instruction to the pre-tightening wrench, instructing the pre-tightening wrench to stop tightening the fastener nut 64 .

[0160] Preferably, during the installation of the fastener, the controller 4 can, after determining that the contact signal emitted by the two contact members has been received, instruct the light-emitting element 3 to emit light 31 through the switch instruction, and send a pre-tightening instruction to the pre-tightening wrench, instructing the pre-tightening wrench to tighten the fastener nut 64 until it is determined that the gap 66 detection result is installed in place, and send a stop instruction to the pre-tightening wrench, instructing the pre-tightening wrench to stop tightening the fastener nut 64.

[0161] Among them, when the controller 4 determines that the gap 66 detection result is to be loosened, it can send a pre-tightening instruction to the pre-tightening wrench, instructing the pre-tightening wrench to loosen the fastener nut 64 until it is determined that the gap 66 detection result is installed in place, and send a stop instruction to the pre-tightening wrench, instructing the pre-tightening wrench to stop twisting the fastener nut 64.

[0162] When the controller 4 determines that the gap 66 detection result is to be tightened, it can send a pre-tightening instruction to the pre-tightening wrench, instructing the pre-tightening wrench to tighten the fastener nut 64 until it is determined that the gap 66 detection result is installed in place, and send a stop instruction to the pre-tightening wrench, instructing the pre-tightening wrench to stop tightening the fastener nut 64.

[0163] It should also be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, commodity or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, commodity or device. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the process, method, commodity or device including the elements.

[0164] Each embodiment in this specification is described in a progressive manner, and the same or similar parts between the embodiments can be referred to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.

[0165] The above is only an embodiment of this specification and is not intended to limit this specification. For those skilled in the art, this specification may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of this specification should be included in the scope of the claims of this application.
