Description

Technical Field

[0001] The utility model relates to the technical field of bridge detection, in particular to a device for measuring the flatness of a bridge rotation support slideway. Background Art

[0002] During the unbalanced rotation of a bridge, in addition to the force applied to the ball joints, some of the supports must also come into contact with the slideway. During the construction of an unbalanced bridge rotation, the supports need to move smoothly along the pre-laid slideway to ensure that the bridge body can accurately rotate into position according to the predetermined trajectory. Therefore, the flatness of the slideway directly affects the smoothness of the rotation process. If the slideway is not flat enough, the supports may encounter resistance during movement, or even "climb" during movement. This will not only increase the required traction but also may cause the rotation operation to become uncontrolled, increasing the difficulty and risk of construction.

[0003] In addition, the support slides are often installed during the early construction of the rotating bridge, but are used during the final rotation. From installation to use, there are multiple construction stages with a long interval. Changes in working conditions during this period may affect the flatness of the slide. Therefore, effective monitoring and maintenance of the slide flatness is one of the important links to ensure the smooth construction of the rotation. Traditional measurement methods usually rely on selecting specific points to evaluate the overall condition of the slide. Although this method can provide some useful information, such as the local slope of the slide, it is difficult to fully reflect the overall flatness of the slide. In addition, in actual applications, the operating space at the support slides in many working conditions is relatively small. In particular, after the upper turntable is installed, the vertical height between the upper turntable and the slide is only about 1m, which further limits the operating space. This makes the operation of traditional measuring tools extremely inconvenient and unable to complete the measurement efficiently.

[0004] In view of the shortcomings of the above-mentioned traditional slideway measurement, this solution proposes a new device for measuring the flatness of the bridge rotation slideway. Utility Model Content

[0005] The utility model aims to provide a device for measuring the flatness of a bridge swivel support slide, which can not only quickly measure the flatness of the support slide under various working conditions, but also has multiple measuring points, which can form a linear diagram of the slide elevation and can intuitively evaluate the slide flatness.

[0006] The basic solution provided by the present utility model is: a device for measuring the flatness of a bridge rotating support leg slide, comprising a mobile bracket assembly, a vehicle type measurement assembly and a track; the track is provided with two groups, and during measurement, the two groups of tracks are respectively provided at the two sides of the support leg slide and arranged relative to each other, and the two groups of tracks are on the same horizontal plane; the two ends of the mobile bracket assembly are respectively slidably connected to the two groups of tracks; the vehicle type measurement assembly is connected to the mobile bracket assembly, and during measurement, the vehicle type measurement assembly is placed on the support leg slide; when the mobile bracket assembly moves, it drives the vehicle type measurement assembly to move on the support leg slide; the vehicle type measurement assembly is provided with an inertial navigation system and an odometer.

[0007] The working principle and advantages of this utility model are:

[0008] For the bridge's rotating support slides whose flatness needs to be measured, the tracks are fixed on both sides of the support slides and arranged relative to each other. The two ends of the mobile bracket assembly are slidingly connected to the two sets of tracks respectively. At the same time, the vehicle type measurement assembly connected to the mobile bracket assembly is placed on the support slides. By pulling / pushing the mobile bracket assembly to move at a constant speed on the track, the vehicle type measurement assembly connected to it is driven to move on the surface of the support slides. During the movement, the inertial navigation system of the vehicle type measurement assembly records the elevation of the traveled path at a high frequency, and the odometer synchronously collects the speed and displacement information of the vehicle type measurement assembly, which can assist the inertial navigation system in obtaining continuous and stable calculation results, thereby realizing the measurement of the flatness of the support slides.

[0009] The measuring device has a simple structure and is easy to operate. It can be efficiently installed on the support slide for measurement. It can not only quickly measure the flatness of the support slide under various working conditions, but also has many measuring points, and can fully and accurately collect the surface data of the support slide with an accuracy of up to 0.1mm. The collected elevation data can form a linear diagram of the slide elevation, which is convenient for subsequent intuitive evaluation of the slide flatness. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Example 1

[0018] The embodiment is basically as shown in the attached Figure 1 、 Figure 2 、 Figure 3 Shown: A bridge swivel support slide flatness measuring device, including a mobile bracket component 1, a vehicle body measurement component 2, a track 6 and a host computer 4.

[0019] There are two groups of tracks 6. During measurement, the two groups of tracks 6 are respectively arranged at the two sides of the support slide 5 and are arranged opposite to each other, and the two groups of tracks 6 are on the same horizontal plane.

[0020] Specifically, in this embodiment, the track 6 is an L-shaped track 6 ; the two sets of tracks 6 are respectively a left track 6 and a right track 6 , which are respectively installed on the left and right edges of the support leg slide 5 ; and are fixed with temporary glue to facilitate the subsequent removal of the track 6 and to minimize the flatness of the support leg slide 5. By providing the track 6 , the lateral displacement of the mobile bracket assembly 1 can be limited, so that the mobile bracket assembly 1 can move strictly along the same path on the support leg slide 5.

[0021] The two ends of the mobile bracket assembly 1 are respectively slidably connected to two sets of tracks 6; the vehicle type measurement assembly 2 is connected to the mobile bracket assembly 1. During measurement, the vehicle type measurement assembly 2 is placed on the support leg slide 5; when the mobile bracket assembly 1 moves, it drives the vehicle type measurement assembly 2 to move on the support leg slide 5; the vehicle type measurement assembly 2 is provided with an inertial navigation system and an odometer.

[0022] In this embodiment, the mobile support assembly 1 includes a transverse support rod 101 and a vertical support rod 102; one end of the transverse support rod 101 is fixedly connected to the middle portion of the vertical support rod 102; the other end of the transverse support rod 101 is provided with a wheel set 103 for cooperating with the track 6; and both ends of the vertical support rod 102 are provided with a wheel set 103 for cooperating with the track 6. Specifically, the wheel sets 103 on the transverse support rod 101 and the vertical support rod 102 are mounted on the bottom surface of the rod body to facilitate cooperating with the track 6.

[0023] The movable bracket assembly 1 is further provided with an auxiliary rod 105 ; the auxiliary rod 105 is used as a handle to facilitate pulling the movable bracket assembly 1 .

[0024] The vehicle model measurement assembly 2 comprises a vehicle plate 201; two sets of wheels 202 are arranged on the front and rear of the bottom of the vehicle plate 201; a box 203 is mounted on the top of the vehicle plate 201; and the inertial navigation system is housed within the box 203. Specifically, the box 203 is provided with a cable hole 204. The host computer 4 is connected to the inertial navigation system via a data cable 205, which passes through the cable hole 204. The host computer 4 is an existing computer.

[0025] The inertial navigation system adopts the existing inertial navigation RTK system, such as the A30 inertial navigation RTK system. The odometer adopts the existing wheel odometer 3. In addition, the odometer is set on the rear side of the vehicle measurement component 2 to obtain speed and displacement information, such as Figure 4 shown.

[0026] A column 206 is provided on the front side of the vehicle plate 201; the vehicle type measurement assembly 2 is connected to the mobile support assembly 1 via the column 206. In this embodiment, the top of the column 206 is fixedly connected to the middle of the transverse support rod 101 of the mobile support assembly 1.

[0027] In a specific application, for the bridge's rotating support runner 5 whose flatness needs to be measured, first clean the runner 5 of debris and gravel. Then, use temporary glue to secure the rails 6 to both sides of the runner 5, positioning them opposite each other. Adjust the position of the mobile support assembly 1 so that the wheels 103 on the horizontal support rods 101 and vertical support rods 102 of the mobile support assembly 1 mate with the corresponding rails 6 and slide relative to them. Simultaneously, the vehicle body measurement assembly 2, connected to the mobile support assembly 1, is placed on the support runner 5.

[0028] By pulling / pushing the mobile support assembly 1 at a constant speed using the auxiliary rod 105, the mobile support assembly 1 is moved, thereby driving the connected vehicle type measurement assembly 2 across the surface of the support runner 5. During this movement, the vehicle type measurement assembly 2's inertial navigation system records the elevation of the traveled path at high frequency and transmits this information to the host computer 4 via data line 205. The odometer simultaneously collects the vehicle type measurement assembly 2's speed and displacement information, assisting the inertial navigation system in obtaining continuous and stable calculation results, thereby enabling the smoothness of the support runner 5 to be measured. Subsequently, the host computer 4 employs existing data analysis methods to analyze and evaluate the smoothness of the support runner 5.

[0029] The present embodiment provides a device for measuring the smoothness of a bridge swivel support slide, which can not only quickly measure the smoothness of the support slide 5 under various working conditions, but also has multiple measurement points, and can form a linear elevation diagram of the slide, enabling intuitive evaluation of the slide smoothness.

[0030] Example 2

[0031] like Figure 5 As shown, a bridge swivel support leg slide flatness measuring device, based on the first embodiment, the outer surface of the transverse support rod 101 is provided with a scale (not shown in the drawings). In this embodiment, the scale is provided on the top surface of the transverse support rod 101.

[0032] The vehicle type measurement assembly 2 is detachably connected to the transverse support rod 101 of the mobile support assembly 1 via bolts. Specifically, a through slot 104 is provided on the side of the transverse support rod 101 .

[0033] A threaded hole 207 is provided on the upper portion of the column 206 of the vehicle type measurement component 2; a bolt is passed through the threaded hole 207 and the through slot 104 and then matched with a nut to firmly connect the vehicle type measurement component 2 to the transverse support rod 101.

[0034] In a specific application, for the bridge's rotating support runner 5 whose flatness needs to be measured, first clean the runner 5 of debris and gravel. Then, use temporary glue to secure the rails 6 to both sides of the runner 5, placing them opposite each other. Adjust the position of the mobile support assembly 1 so that the wheels 103 on the horizontal support rods 101 and vertical support rods 102 of the mobile support assembly 1 are aligned with the corresponding rails 6 and slide relative to them. At the same time, place the vehicle body measurement assembly 2 on the support runner 5.

[0035] Refer to the scale ruler, select the connection position between the vehicle type measurement component 2 and the mobile bracket component 1, and use bolts to pass through the threaded holes 207 and the through slots 104, and then use nuts to fully tighten the bolts to firmly connect the vehicle type measurement component 2 to a specified position of the transverse bracket rod 101, thereby determining the first driving path of the vehicle type measurement component 2.

[0036] By pulling or pushing the mobile support assembly 1 at a constant speed through auxiliary rod 105, the mobile support assembly 1 is moved, thereby driving the connected vehicle type measurement assembly 2 to move along the surface of the support slide 5. During this movement, the vehicle type measurement assembly 2's inertial navigation system frequently records the elevation of the traveled path and transmits this information to the host computer 4 via data line 205. The odometer simultaneously collects the vehicle type measurement assembly 2's speed and displacement information, assisting the inertial navigation system in obtaining continuous and stable calculation results.

[0037] The auxiliary rod 105 can be used to drive the vehicle type measurement component 2 to move back and forth three times on the first driving path to fully collect data and reduce accidental errors.

[0038] Then adjust the connection position between the vehicle type measurement component 2 and the mobile bracket component 1 (specifically, loosen the nut and change the connection locking position between the vehicle type measurement component 2 and the transverse bracket rod 101) to determine the second driving path of the vehicle type measurement component 2; and repeatedly drive the vehicle type measurement component 2 back and forth on the driving path three times to fully collect data. Optionally, the connection position between the vehicle type measurement component 2 and the mobile bracket component 1 can be further adjusted to collect more data. This will achieve the measurement of the flatness of the support slide 5. Subsequently, through the host computer 4, using existing data analysis methods, the flatness of the support slide 5 can be analyzed and evaluated.

[0039] The present embodiment provides a device for measuring the flatness of a bridge rotating support leg slide. Compared with the first embodiment, the connection position of the vehicle body measurement component 2 and the mobile bracket component 1 can be quickly adjusted as needed, and the connection position can be accurately adjusted with reference to the scale ruler, so as to facilitate the collection of flatness data of the support leg slide 5 on different paths. The measurement range is larger, and richer and more comprehensive data reference can be provided for the flatness evaluation of the support leg slide 5.
