Description

Technical Field

[0001] This utility model belongs to the field of track support platform testing technology, and in particular relates to a measuring device for track support platforms of ballastless tracks. Background Technology

[0002] After the overall track bed construction is completed, the spatial position and dimensions of the track support platform of the newly built slab track and double-block track need to be precisely measured and the smoothness analysis and evaluation need to be carried out. This provides data support for the subsequent long rail fine-tuning operation and fastener procurement and installation. Therefore, the inspection of the track support platform is crucial, and the quality of the inspection results will directly affect the quality and efficiency of the track fine-tuning construction.

[0003] Currently, the measuring devices used for ballastless track support platforms are typically a combination of an automatic total station and a track slab fine-tuning frame. During measurement, the surveyor needs to precisely place the fine-tuning frame on the support platform, accurately measure the prisms on the frame, and then place the frame on the next support platform after each measurement, repeating this process to measure all support platforms. The problems with this measuring device are low automation, low measurement efficiency, a heavy workload for surveyors, and the reliance on a single measurement method leads to a lack of comparability in the results, making them more prone to errors.

[0008] As a further preferred embodiment of this technical solution, the positioning module includes a left positioning module and a right positioning module, which are symmetrically mounted on the front moving block.

[0009] As a further preferred embodiment of this technical solution, both the left positioning module and the right positioning module include a lifting column, a telescopic component, a rotating component, and a camera.

The rotating component and the telescopic component are in the same horizontal plane, with one end of the rotating component hinged to the telescopic component and the other end connected to the camera. The camera is mounted below the end of the rotating component, and its shooting angle is downward.

[0010] As a further preferred embodiment of this technical solution, the measuring module includes a support plate, which is fixedly connected to the connecting plate. Telescopic cylinders are installed below both ends of the support plate, the telescopic cylinders are perpendicular to the support plate, and the lower end of the telescopic cylinder is connected to the measuring instrument.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example

[0022] like Figures 1 to 2 The measuring device shown for ballastless track support platforms includes a traveling module that moves between two rows of ballastless track support platforms. A positioning module and a measuring module are mounted on the traveling module. The positioning module is located at the front end of the traveling module. Multiple sets of measuring modules are arranged along the length of the traveling module, each set corresponding to multiple pairs of continuously arranged ballastless track support platforms. Different measuring instruments 303 are mounted on each set of measuring modules. The device also includes a controller mounted on the traveling module, and the traveling module, positioning module, and measuring module are all electrically connected to the controller.

[0023] In this embodiment, the main function of the walking module is to control the change of the measuring device's work position through the walking command of the controller; the main function of the positioning module is to control the positioning of the measuring device's work position through the positioning command of the controller, and it can cooperate with the walking module to move the measuring device to the designated position, ensuring that the measuring module corresponds precisely to the ballastless track support platform to be measured; the main function of the measuring module is to control the measurement of the ballastless track support platform through the measurement command of the controller.

[0024] The advantages of this embodiment compared to existing measuring devices are as follows: First, by replacing traditional manual movement with a walking module, the workload of measuring personnel can be reduced and the measuring efficiency improved; Second, by using a positioning module to locate the specific position of the current measuring device, and cooperating with the walking module to ensure that the measuring module accurately corresponds to the ballastless track support platform to be measured, thus guaranteeing the measuring accuracy; Third, by using different measuring instruments on multiple sets of measuring devices to measure the same pair of ballastless track support platforms separately, the final measuring data can be balanced, further reducing the measuring error and improving the measuring accuracy.

[0025] It should be noted that the different measuring instruments 303 mentioned above refer to measuring instruments that use different measurement methods to achieve the same measurement purpose. The reason for this setting is that all types of measuring instruments on the market will produce certain measurement errors. Using different measuring instruments to perform measurements separately can play a relatively balancing role, so as to eliminate the unilateral measurement errors brought about by a single measuring instrument, and make the final measurement data tend to be at a central level, thereby achieving the purpose of reducing errors and improving accuracy.

[0026] In addition, the aforementioned measuring instrument 303 is a commercially available finished instrument for measuring ballastless track bearing platforms. Those skilled in the art can select the appropriate measuring instrument 303 according to the actual parameters to be measured, and its specific structure will not be described in detail here.

[0027] More specifically, the walking module includes a front moving block 101 and a rear moving block 102, which are connected by a connecting plate 103. Multiple walking wheels 104 are installed at the bottom of both the front moving block 101 and the rear moving block 102.

[0028] In this embodiment, the walking module is in the shape of a rectangular frame. There are three connecting plates 103. The two ends of the three connecting plates 103 are fixedly connected to the front moving block 101 and the rear moving block 102, respectively, and are distributed at equal intervals. There are four walking wheels 104. The four walking wheels are located at the four corners of the bottom of the front moving block 101 and the rear moving block 102.

[0029] More specifically, the positioning module includes a left positioning module and a right positioning module, which are symmetrically installed on the front moving block 101. The left positioning module and the right positioning module are used to position the ballastless track support platforms on both sides of the measuring device to ensure accurate positioning and precise station movement.

[0030] In this embodiment, both the left positioning module and the right positioning module include a lifting column 201, a telescopic component 202, a rotating component 203, and a camera 204. The lifting column 201 is vertically mounted on the front moving block 101. The telescopic component 202 is perpendicular to the lifting column 201, and one end of the telescopic component 202 is fixedly connected to the outer side of the top of the lifting column 201, while the other end is connected to the rotating component 203. The rotating component 203 and the telescopic component 202 are in the same horizontal plane, and one end of the rotating component 203 is hinged to the telescopic component 202, while the other end is connected to the camera 204. The camera 204 is mounted below the end of the rotating component 203, and its shooting angle is downward.

[0031] It should be noted that the driving methods of the lifting column 201, telescopic component 202, and rotating component 203 are all conventional. For example, the lifting column 201 can be raised and lowered by a lifting cylinder, the telescopic component 202 can be telescopic by a telescopic cylinder, and the rotating component 203 is driven by a small motor. The driving devices are uniformly controlled by a controller.

[0032] Its specific working principle is as follows: The lifting column 201 can move up and down, which in turn drives the telescopic component 202 on it to move up and down. The telescopic component 202 can extend and retract on the horizontal plane, which in turn drives the rotating component 203 on it to extend and retract. The rotating component 203 can rotate on the horizontal plane around its hinge point with the telescopic component 202, which in turn drives the camera 204 to rotate. The camera 204 is mainly used to capture real-time images of the ballastless track support platform below. Through the cooperation of the lifting column 201, the telescopic component 202 and the rotating component 203, the camera 204 can move in multiple directions, so that its shooting range can cover multiple support platforms in the ballastless track support platform on one side, providing a sufficient image basis for subsequent positioning analysis. The image information captured by the camera 204 will be transmitted to the controller. Through the image analysis function of the controller, the current position of the measuring device and the distance to be moved for the next position movement are obtained.

[0033] More specifically, the measuring module includes a support plate 301, which is fixedly connected to the connecting plate 103. Telescopic cylinders 302 are installed below both ends of the support plate 301. The telescopic cylinders 302 are perpendicular to the support plate 301, and the lower end of the telescopic cylinders 302 is connected to the measuring instrument 303. The telescopic cylinders 302 can drive the measuring instrument 303 to move up and down so that the measuring instrument 303 can dock with the rail support platform to be measured.

[0034] In this embodiment, the measuring instrument 303 is embedded; the measuring module is provided in two sets, and the two sets of measuring modules correspond to two adjacent pairs of ballastless track support platforms.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
