Detailed Description
In order that the above-recited objects, features and advantages of the present invention will be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings and appended detailed description. It should be noted that, without conflict, the embodiments of the present invention and features in the embodiments may be combined with each other.
The embodiment of the invention provides a press fit device, as shown in fig. 2-6, and also provides a data acquisition device and a data acquisition system, which can be applied to the process of data acquisition of a third rail 9 of a subway or a train. The data acquisition system comprises a running mechanism (not shown in the figure) and the data acquisition equipment, wherein the data acquisition equipment comprises the compression fit device and the acquisition mechanism. The running mechanism can be a carriage of a subway or a train, and the like, can realize the purpose of driving the whole data acquisition equipment to move by means of rolling fit of wheels of the running mechanism and a running rail, and of course, the running mechanism can also be a self-propelled trolley and other tools, and is not limited at this time.
As shown in fig. 2-6, the data acquisition device comprises a mounting frame 1, a pressing part 2, a matching mechanism 3 and an acquisition mechanism 4, wherein the mounting frame 1 is a mounting foundation of the whole data acquisition device, and in the actual use process, the whole data acquisition device can be mounted on a running mechanism such as a train by means of the mounting frame 1, so that the data acquisition device can automatically walk along the extending direction of the third rail 9 under the driving of the running mechanism, and further the data acquisition work on the third rail 9 is completed.
Specifically, the mounting frame 1 may be made of a material with relatively high structural strength such as metal and deformation resistance, and the specific shape and structure thereof may be determined according to practical situations, which is not limited herein. For example, the mounting frame 1 may be provided with a connection structure such as a connection hole, so that the mounting frame 1 may be fixedly mounted to the running gear by means of a screw connection, a rivet connection, or a clip connection. In addition, the whole data acquisition device can be arranged on one side of the third rail 9 facing the ground so as to acquire data on the side of the third rail 9 which is not easy to observe.
As shown in fig. 2 and 5, the matching mechanism 3 is disposed on one side of the third rail 9 waiting for the acquisition component, and the matching mechanism 3 includes at least two matching portions 31, where the matching portions 31 are movably connected with the third rail 9, so as to ensure that the matching mechanism 3 can form a stable matching relationship with the third rail 9 during the data acquisition process. Further, the movable connection between the engaging portion 31 and the third rail 9 may be a sliding connection or a rolling connection, which is not limited herein. More specifically, the fitting portions 31 may be provided with two, three or more, and each fitting portion 31 may be distributed in the same direction, which may ensure that each fitting portion 31 may form a movable connection relationship with the third rail 9; in the process of assembling the plurality of fitting portions 31, the fitting portions 31 may be connected to each other by a bracket or a connecting frame, etc., so that the plurality of fitting portions 31 in the fitting mechanism 3 are connected as a unit. In addition, in the data acquisition device, since the acquisition mechanism 4 is mounted on the mating mechanism 3, the plurality of mating parts 31 can form a relatively fixed mating relationship with the aid of the acquisition mechanism 4, so that on the one hand, parts for partially connecting can be omitted, and on the other hand, under the combined action of the plurality of mating parts 31, the orientation of the acquisition mechanism 4 can be basically ensured to be changed along with the change of the orientation of the whole mating mechanism 3.
As shown in fig. 2 and 6, in the assembly process of the data acquisition device, at least two matching parts 31 are movably connected with the mounting frame 1 through the pressing parts 2, that is, at least two pressing parts 2 are provided, and opposite ends of each pressing part 2 can be respectively connected with the mounting frame 1 and the matching parts 31, so that under the action of the pressing parts 2, the matching parts 31 can have the capability of moving along the stretching direction of the pressing parts 2 relative to the mounting frame 1, and further in the process of matching the matching mechanism 3 with the third rail 9, the at least two matching parts 31 can be basically ensured to be always kept in close contact with the same side face of the third rail 9 through the provided pressing parts 2, that is, each matching part 31 can change the orientation of the whole matching mechanism 3 along with the trend change of the third rail 9.
Specifically, the pressing portion 2 may be a member having a telescopic capability and capable of changing its maximum length, and may be a member that actively generates a telescopic force, and for example, the pressing portion 2 may be a member such as a pressing cylinder, a hydraulic cylinder, or a linear motor. The opposite ends of the pressing part 2 are respectively connected to the mounting frame and the matching part 31, and the pressing part 2 is lifted or retracted in a preset mode, so that the matching part 31 is lifted or retracted relative to the mounting frame 1, and the matching part 31 can respectively complete the matching work with the inlet section 91, the horizontal section 92 and the outlet section 93. Alternatively, the compressing part 2 may be a part for passively generating the expansion force, for example, it may be a rubber block or a compression spring, preferably, the compressing part 2 may be a compression spring, which makes the whole structure of the compressing part 2 simpler, fewer parts and lower cost; the compressing part 2 of the compressing spring has high elasticity, and the compressing amount of the compressing spring is relatively large, so that the movable distance of the matching part 31 relative to the mounting frame 1 is larger, and the compressing part is more suitable for matching with a part with relatively large interval between the highest point and the lowest point of the third rail 9. The opposite ends of the pressing portion 2 may be fixedly connected to the mounting frame 1 and the mating portion 31, respectively, by welding or clamping. In addition, in the process of designing and producing the whole data acquisition equipment, according to the actual conditions such as the position relationship among the mounting frame 1, the matching mechanism 3 and the third rail 9, a compression spring with the natural length meeting the working requirement can be selected as the compression part 2, so that when the matching part 31 starts to be matched with the inlet section 91, the compression part 2 has a certain initial elasticity, and a certain force can be provided for the matching part 31 when the compression part 2 is at the maximum length, so that a stable close contact relationship is always formed between the matching part 31 and the third rail 9 when the matching part is waiting for matching.
The types of data collected by the collection mechanism 4 may be various, and are not limited herein, and those skilled in the art can flexibly change the types of components in the collection mechanism 4 according to actual situations, so as to obtain the data of the required types. The collection mechanism 4 and the matching parts 31 can form a fixed connection relationship through a threaded connector and the like, or the collection mechanism 4 can be connected between the two matching parts 31 in a clamping, welding and other modes. Moreover, in the vertical direction, a set interval may be provided between the collecting mechanism 4 and the mating portion 31, so as to ensure that the collecting mechanism 4 can work normally, that is, obtain corresponding data of the third rail 9.
Specifically, the acquisition mechanism 4 may include an image acquisition device such as a camera or an infrared camera, or may further include a size acquisition device such as a distance sensor, and those skilled in the art may flexibly select a specific type of a component for generating a data acquisition effect in the acquisition mechanism 4 according to actual requirements.
Still further, as shown in fig. 3, the collecting mechanism 4 may include a camera 41 and a light source 42, where the light source 42 may be connected to one side of the camera 41, and the light source 42 is oriented substantially in the same direction as the camera 41, that is, the axial direction of the lens of the camera 41 is substantially the same as the emission direction of the light source 42, so that during the working process of the whole data collecting device, a light supplementing effect may be provided for the camera 41 by means of the light source 42, so as to ensure that the definition and quality of the data such as the image collected by the camera 41 are relatively higher. Specifically, the model and specification of the camera 41 may be selected according to actual requirements, which are not limited herein; the light source 42 may be a component capable of generating light, including a flash or a light band; more specifically, the light source 42 itself may be provided with an energizing means such as a battery, or both the light source 42 and the camera 41 may use the same energizing means in common to further reduce the number of parts in the overall data acquisition device. Alternatively, as shown in fig. 3, at least two light sources 42 may be provided, and two light sources 42 may be provided at opposite sides of the camera 41, respectively, to further enhance the generated light supplementing effect. In addition, the orientation of the light source 42 can also be changed by corresponding means during the installation of the light source 42. For example, the light source 42 may be rotated relative to the camera 41, so that in some cases, the light source 42 may provide better light compensation for objects within the field of view of the camera 41 by changing its orientation.
As can be seen from the above, in the process of waiting for the third rail 9 to acquire data of the acquisition component, the data acquisition device provided by the invention can be matched with the third rail 9 through at least two matching parts 31, and in the process of mutually matching the matching parts 31 with the third rail 9, the matching parts 31 can move relative to the mounting frame 1 under the action of the pressing part 2, so that no matter which part of the third rail 9 is matched with the matching parts 31, the whole matching mechanism 3 can form a close matching relationship with the third rail 9 under the action of the pressing part 2, and further, the purpose of acquiring complete data information of the third rail 9 can be completed under the action of the acquisition mechanism 4.
Further, as shown in fig. 2 and 3, preferably, the mounting bracket 1 may include a mounting portion 11, a connection portion 12, and a supporting portion 13, wherein the supporting portion 13 and the mounting portion 11 are respectively provided at opposite sides of the connection portion 12, and during the mounting of the data acquisition device, the entire device may be mounted on a train or a traveling mechanism by means of the mounting portion 11; the connection portion 12 may be used to connect the mounting portion 11 and the supporting portion 13, thereby forming the entire mount 1; the supporting portion 13 may provide a supporting base for the pressing portion 2, preventing the pressing portion 2 from malfunctioning due to unstable support during movement, so that the mating portion 31 may not be able to form a tight mating relationship with the third rail 9. In the case where the pressing portion 2 employs a compression spring, preferably, the supporting portion 13 may be a plate-like structure, and the supporting portion 13 of the plate-like structure may provide a better supporting and retaining effect for the pressing portion 2, thereby preventing the pressing portion 2 from being bent or deformed during compression.
Specifically, the mounting portion 11, the connecting portion 12 and the supporting portion 13 may be made of metal materials, and may be formed in a split molding manner, and the mounting portion 11 may be provided with a mounting hole so as to connect the mounting portion 11 to a train or a travelling mechanism through a threaded connector or the like; the connection portion 12 may have a long bar-shaped structure, and as shown in fig. 4, the mounting portion 11 may be connected to a middle portion of the connection portion 12. Of course, the mounting portion 11, the connecting portion 12 and the supporting portion 13 may be formed in an integrally formed manner, which may further improve the structural strength and stability of the entire mounting bracket 1. In addition, as shown in fig. 2, in order to further simplify the structural complexity of the whole data acquisition device, preferably, the number of the mounting frames 1 may be identical to the number of the mating portions 31, so that each mounting frame 1 may be configured independently of each mating portion 31, avoiding that a large-sized component must be disposed in the whole mounting frame 1, and a plurality of mating portions 31 are disposed at a connection interval.
Further, in the case that the compressing portion 2 employs a compression spring, two supporting portions 13 may be provided, and the two supporting portions 13 may be respectively connected to opposite ends of the connecting portion 12, an accommodating space may be formed between the two supporting portions 13 to mount the compressing portion 2 by means of the accommodating space, and accordingly, a portion of the fitting portion 31 that is fitted with the compressing portion 2 may also be provided in the accommodating space to ensure that the compressing portion 2 can produce an effective compressing effect on the fitting portion 31, and of course, the fitting portion 31 may also be fitted with the compressing portion 2 by means of other components, and at this time, the other components may be made to extend into the accommodating space and be fitted with the compressing portion 2. In addition, in the process of designing and assembling the whole data acquisition device, the distance between the two supporting parts 13 can be smaller than the length of the compressing part 2 in a natural state, so that the compressing part 2 is ensured to have a certain initial elastic force after being installed between the two supporting parts 13, the initial elastic force can act on the matching part 31, and the matching part 31 can form a tight matching relationship with the surface of the third rail 9 under the action of the elastic force.
In addition, in the design and assembly process of the data acquisition device provided by the embodiment of the invention, the dimensions of the mounting frame 1 and the matching mechanism 3 can be flexibly designed according to the actual dimensions of the to-be-matched third rail 9 waiting for the acquisition component, so that when the mounting frame 1 is mounted on the travelling mechanism and the compression part 2 is in the state of minimum compression, the height of the matching part 31 can be slightly lower than the height of the inlet section 91 of the third rail 9, so that the matching part 31 can be mutually matched with the inlet section 91 of the third rail 9 when the data acquisition device moves to the inlet section 91 of the third rail 9, and the height of the matching part 31 can be reduced by compressing the compression part 2 in the process of moving along the third rail 9, and when the matching part 31 is matched with the horizontal section 92, the matching part 31 reaches the lowest point, and at this time, the compression part 2 is in the state of maximum compression.
In order to further prevent the compression part 2 from bending or deforming during the expansion and contraction process, further, as shown in fig. 2, 3 and 4, the data acquisition device provided by the embodiment of the invention further includes a guiding part 7, where the guiding part 7 is matched with the compression part 2, so that the compression part 2 can generate expansion and contraction motion along the extending direction of the guiding part 7, which can ensure that the compression part 2 basically does not bend or deform. Specifically, the guide portion 7 may be a guide groove, which may be formed on a setting structure, and the structure may be connected to the mounting frame 1 or the mating mechanism 3, so that the compression portion 2 may generate a telescopic action under the action of the guide portion 7 during the operation of the whole data acquisition device.
Under the condition that compression springs are adopted by the compression part 2, preferably, the guide part 7 can be a guide rod, in the process of assembling the data acquisition equipment, the compression part 2 can be sleeved on the guide rod, the opposite ends of the guide rod are relatively fixed with the mounting frame 1, specifically, the two ends of the guide rod can be fixedly connected to the two support parts 13 of the mounting frame 1 in a welding, threaded connection mode and the like, and further under the action of the guide rod, the compression springs can be prevented from deforming or bending in the expansion process, so that the compression part 2 can work normally.
Specifically, during the process of assembling the data acquisition device, the mating part 31 may be mounted between the two supporting parts 13 through other components, for example, as shown in fig. 3, the mating mechanism 3 may further include a base frame 32 to provide a mounting base for the plurality of mating parts 31 by means of the base frame 32, accordingly, the mating parts 31 may extend between the two supporting parts 13 through the base frame 32, and the base frame 32 may also be sleeved on the guide rod, so that the elastic force of the pressing part 2 may act on the mating parts 31 under the action of the base frame 32.
In order to ensure a smoother matching relationship between the base frame 32 and the guide rod, preferably, as shown in fig. 3 and fig. 4, the data acquisition device provided by the embodiment of the invention may further include a linear bearing 8, where the linear bearing 8 is movably connected with the guide portion 7, so as to ensure a more stable and smooth matching relationship between the matching portion 31 and the guide portion 7. Correspondingly, one end of the compression spring is connected with the mounting frame 1, and the other end of the compression spring is matched with the linear bearing 8, so that the matching part 31 and the mounting frame 1 can form a movable connection relationship in the telescopic direction of the compression part 2.
More specifically, in assembling the data acquisition device, the pressing portion 2 and the linear bearing 8 may be mounted on the guide portion 7 first; the type and the specification of the linear bearing 8 may be determined according to the size of the guide 7 and the specification of the compression spring, which is not limited herein. It should be noted that, in the whole data acquisition device, two, three or more matching parts 31 may be provided, in the case that two or more matching parts 31 are provided, only two of the matching parts 31 may be provided with the pressing part 2, and the mounting frame 1, the guiding part 7 and the linear bearing 8, so that the total number of parts in the whole data acquisition device is reduced as much as possible under the condition that the matching mechanism 3 is ensured to have the capability of changing the direction along with the change of the direction of the third rail 9, on one hand, spare parts, assembly and maintenance costs can be reduced, and on the other hand, the whole weight of the whole data acquisition device can be reduced, thereby achieving the purposes of improving the whole working performance and the service life of the data acquisition device.
Further, as shown in fig. 2, the matching portion 31 may be a roller, so that the whole matching mechanism 3 and the third rail 9 wait for the acquisition components to form a rolling connection relationship, on one hand, the matching stability between the matching mechanism 3 and the third rail 9 can be further improved, and on the other hand, the vibration amplitude generated in the process of relatively moving the whole acquisition mechanism 4 and the third rail 9 can be reduced, so that the stability of the acquisition mechanism 4 is improved, and the precision and the definition of the data acquired by the acquisition mechanism 4 are improved; in addition, the friction force between the matching part 31 and the third rail 9 can be reduced, so that the service life of the whole data acquisition mechanism 4 is prolonged.
Specifically, the engaging portion 31 may be a roller with a cylindrical structure, which may ensure that the engaging relationship between the roller and the third rail 9 is more stable, and the dimension of the roller in the axial direction thereof may be determined according to the specific dimension of the third rail 9 to be engaged, which is not limited herein. As described above, the engaging portions 31 may be mounted on the base frame 32 through the wheel shafts, and a predetermined interval may be provided between the engaging portions 31 to ensure that each engaging portion 31 can roll on the surface of the third rail 9 without interference.
More specifically, as shown in fig. 2, 3 and 4, the mating mechanism 3 may include only two mating portions 31, where the two mating portions 31 are rollers, and the two mating portions 31 are rotatably mounted on two base frames 32, respectively, and each base frame 32 is connected to the guiding portion 7, so as to ensure that each mating portion 31 can form a stable close mating relationship with the third rail 9.
Further, as shown in fig. 2 and fig. 4, the matching mechanism 3 may further include a collection bracket 33, the collection mechanism 4 may be mounted on the collection bracket 33, so as to further improve stability of the collection mechanism 4, and in a process of assembling the data collection mechanism 4, the collection mechanism 4 may be connected to the collection bracket 33 first, then the whole formed by the collection mechanism 4 and the collection bracket may be fixedly connected to the two base frames 32 in the matching mechanism 3, the collection bracket 33 may be specifically made of a hard material such as metal, so as to ensure that the collection bracket 33 and the two base frames 32 have higher structural strength and structural stability, and further may be fixedly connected together by welding, and the two base frames 32 are movably connected to the mounting frame 1 through the pressing portion 2, so that the collection bracket 33 and the mounting frame 1 may also relatively move in a telescopic direction of the pressing portion 2. In addition, in order to further improve the accuracy and definition of the acquired data, it is preferable that the acquisition mechanism 4 be centered with respect to the roller along the axial direction of the roller, specifically, the lens of the camera 41 be centered with respect to each mating portion 31, as shown in fig. 3, in which case, the image acquired by the camera 41 may be relatively wider, and the definition of the acquired data such as the image may be higher, and less likely to be distorted.
Preferably, as shown in fig. 2, the data acquisition device provided by the embodiment of the present invention may further include a rotating shaft 6, during the process of connecting the acquisition bracket 33 and the mounting frame 1, the rotation connection relationship between the acquisition bracket 33 and the mounting frame 1 may be formed by means of the rotating shaft 6, so that during the working process of the data acquisition device, when the press-fit device runs to the junction between the inlet section 91 and the horizontal section 92 or the junction between the horizontal section 92 and the outlet section 93 in the third rail 9, the press-fit device may be ensured to form a mutually perpendicular relationship with the third rail 9 more rapidly and more stably.
For example, in the process that the data acquisition device enters the horizontal section 92 from the inlet section 91, compared with the rear mating section 31, the front mating section 31 can move from the inlet section 91 to the horizontal section 92 earlier, because the inlet section 91 is arranged upward compared with the horizontal section 92, under the influence of the structure of the third rail 9, the front mating section 31 can apply a certain downward pressure to the pressing section 2, so that the position of the front mating section 31 is lower than that of the rear mating section 31, and the two mating sections 31 are respectively fixed relatively to the acquisition bracket 33 through the corresponding base frames 32, at this time, since the acquisition bracket 33 and the two mounting frames 1 are connected through the rotating shafts 6, when the front mating section 31 moves to the horizontal section 92, the height of the rear mating section 31 is continuously reduced under the condition that the height of the front mating section 31 is unchanged, so that the whole acquisition bracket 33 generates a certain angle relative to the mounting frame 1, and further, the rear mating section 31 can be kept in a tight and vertical relation with the third rail 9 and the rear section 92 can be kept in a tight and vertical relation with the horizontal section 92, and the acquisition mechanism can be completely vertical to the rear section 9.
Specifically, the base frame 32 may include two parts, one part may be provided with a through hole so as to be sleeved on the guide rod, the mating part 31 may be mounted on the other part of the base frame 32, and the collecting bracket 33 may be fixedly connected between the respective other parts of the two base frames 32, and the two parts of the base frames 32 may form a rotational connection relationship through the rotation shaft 6, so as to ensure that the collecting bracket 33 may rotate relative to the mounting frame 1. More specifically, as shown in fig. 2, the axial direction of the rotation shaft 6 and the expansion and contraction direction of the pressing portion 2 may be made perpendicular to each other.
As described above, in the process of moving the entire fitting mechanism 3 from the inlet section 91 to the horizontal section 92, and from the horizontal section 92 to the outlet section 93, it is inevitable that the partial structure of the third rail 9 where the collecting mechanism 4 cannot be completely opposed to itself is in a mutually perpendicular relationship, but in consideration of the relatively high moving speed of the train or the traveling mechanism that moves the data collecting mechanism 4, the interval between the two fitting portions 31 located in front and at rear is relatively small compared to the length of the third rail 9, and thus, the time in which the incompletely perpendicular relationship occurs between the collecting mechanism 4 and the third rail 9 is relatively short, which is almost negligible.
In order to further reduce the adverse effects of the foregoing process on the data acquisition result, preferably, in the process of designing and producing the data acquisition device, under the condition that the acquisition mechanism 4 has an acquisition angle meeting the requirement, the distance between the two matching parts 31 can be made as small as possible, so that the length of the path (or time) of the acquisition mechanism 4 which is not completely perpendicular to the third rail 9 is further shortened, and the overall accuracy and definition of the acquired data are further improved.
