Description

Technical Field

[0001] The utility model relates to the technical field of traffic track engineering equipment, in particular to a tool for controlling the elevation of a linear motor induction plate. Background Art

[0002] The induction plate is used in the linear motor transport system of urban rail transit vehicles. It is a short stator linear induction motor (LIM). Its structural principle is to cut the rotating motor along the steering direction and unfold it into a straight line. The stator (primary coil) is set on the bogie at the bottom of the vehicle, and the rotor (secondary coil) is the induction plate set in the middle of the line. When the stator installed on the vehicle bogie interacts with the induction plate laid in the middle of the line when powered on to generate a moving magnetic field, and generates traction through the interaction between magnetic forces (repulsion or attraction). At this time, by changing the direction of the magnetic field, the vehicle can be operated and braked. Therefore, the induction plate is one of the key equipment in the linear motor transport system of urban rail transit. When the induction plate is installed, the elevation of the upper surface of the induction plate is 15mm above the rail surface, and the accuracy error of its elevation is required to be between +1mm and -2mm. How to quickly, accurately and accurately measure the elevation of the induction plate during the laying process is a major technical problem in the installation process of the induction plate.

[0003] Linear motor induction plates can be roughly divided into three types according to their length: 5-meter plate, 2.5-meter plate, and 1.25-meter plate. The number of points for induction plate elevation measurement varies according to the length of the plate. A 5-meter plate measures 18 points, a 2.5-meter plate measures 10 points, and a 1.25-meter plate measures 6 points. When measuring the elevation of the induction plate of an urban rail transit track project, there is an existing solution for measuring the elevation of the induction plate.

[0004] The existing treatment method basically adopts the following construction plan: after the induction plate is basically in place, pull a 20mm high string on the top of the rail of the same section on both sides of the induction plate, so that the string crosses the left and right measuring points of the induction plate. At this time, the left and right strings and the left and right measuring points of the induction plate are on the same straight line, and the string is tightened; use a tape measure to measure the height difference between the string at the measuring point and the induction plate surface, and subtract 20mm to get the elevation of the induction plate surface relative to the rail surface, and then compare it with 15mm (+1mm~-2mm), which is the value that needs to be adjusted; because the surface of the induction plate is made of aluminum, it is very easy to be damaged or scratched, so a steel ruler must not be used for measurement. After a pair of induction plate measuring points are completed, adjust the adjustment plate under the induction plate to adjust the elevation of the induction plate within the error range, and then re-measure the next measuring point.

[0005] However, the efficiency of elevation measurement during the installation of the induction plate directly affects the progress of the installation and construction of the induction plate. The existing construction plan has the following disadvantages: 1. The elevation accuracy of the induction plate is high. The traditional method uses strings and tape measures to measure the degree manually. There is no precise equipment, and the measurement error is uncontrollable. The measured value is easily affected by the tightness of the string, and there are many locations that need to be rectified later; 2. There are many small measuring instruments used in the elevation measurement of the induction plate, which requires multiple people to cooperate in the measurement, and the labor input is large; 3. When adjusting the elevation of the induction plate, the existing construction plan is cumbersome and requires repeated measurements. The efficiency is not high, which seriously affects the overall construction progress of the project. Utility Model Content

[0006] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a tool for controlling the elevation of a linear motor induction plate, which can simplify the elevation measurement process of the induction plate, can quickly measure the elevation of the induction plate, improve construction quality, and reduce the risk of construction rectification.

[0007] The purpose of the utility model is achieved through the following technical solutions: a tool for controlling the elevation of a linear motor induction plate, comprising a crossbeam and a measuring component, wherein the two ends of the crossbeam are respectively provided with a first positioning component and a second positioning component, wherein the measuring component comprises a slide seat slidably mounted on the crossbeam and used to measure the lateral distance of a measuring point of the induction plate, and a caliper mounted on the slide seat and used to measure the vertical distance of a measuring point of the induction plate, a scale for marking the lateral distance is arranged on the surface of the crossbeam, a probe of the caliper is arranged perpendicular to the induction plate, and the probe contacts the induction plate during measurement, and the probe is both a probe for the vertical distance and a probe for the vertical distance, the first positioning component is an adjustable component, the first positioning component is composed of a first positioning plate, a first stopper slidably mounted on the first positioning plate, and an elastic element mounted between the first positioning plate and the first stopper, the second positioning component is composed of a second positioning plate and a second stopper fixedly mounted on the second positioning plate, and limiting steps for positioning on the rails on both sides of the induction plate are formed between the first stopper and the first positioning plate, and between the second stopper and the second positioning plate.

[0008] The caliper is a digital caliper, which is a common digital display electronic device that can be accurate to 0.01mm, has clear readings, is sensitive to response, and has a zeroing device. After setting any height as the zero point, move the internal measuring scale, and the number displayed on the digital display screen is the height difference between the bottom of the measuring scale and the zero point. The probe of the caliper can move up and down in the vertical direction perpendicular to the upper surface of the induction plate, and is flexible and unobstructed when moving.

[0009] The accuracy of the scale is 1mm. The scale is a set of digital marks engraved on the upper surface of the beam in mm. A straight line of one-quarter the width of the beam is set every 1mm without any numbers, a straight line of one-half the width of the beam is set every 10mm without any numbers, a straight line mark across the beam is set every 100mm, and clear digital marks of 100mm, 200m, 300mm... are set. When setting, the center of the beam is used as the origin (0mm), and the numbers are derived to the left and right, and they gradually increase.

[0010] The elastic element is a spring, one end of which is connected to the first positioning plate, and the other end of which is connected to the first stopper.

[0011] The crossbeam is provided with a first track for the sliding seat, the first positioning plate is provided with a second track for the sliding of the first stopper, and the first track is arranged in parallel with the second track. It should be noted that the types of the moving pair are relatively large and the present application can adopt the moving pair of existing means.

[0012] The cross section of the cross beam is rectangular, and the upper surface of the cross beam is a first track.

[0013] The bottom surfaces of the first stopper and the second stopper are flush.

[0014] Due to the reasons such as the track gauge error of 1435 (+2~-1) mm, the main line track gauge of 1435 mm, the widened track gauge of the parking lot section of 1440 mm, and the turnout track gauge of 1435 mm-1445 mm, this application was designed to ensure that it can be stable on the rails and can be used normally at different track gauge positions. Therefore, this application draws on the idea of ​​the existing universal track ruler and sets two blocks at the inner rail head position of the rail. One block is set on the left and the other on the right and is connected by a crossbeam. One of them is fixed on the crossbeam and is close to the inner rail head of the rail when in use. The other block is equipped with a spring reset device, which can be stretched to the inside of the rail and close to the inner rail head on this side after the force is removed. At this time, regardless of the track gauge, this application can be fixed normally on the rail and remain perpendicular to the rail.

[0015] The beneficial effects of the utility model are as follows: (1) it solves the problem of lack of professional measuring tools in the process of installing the induction plate, and designs an applicable tool for measuring the elevation of the induction plate; (2) by arranging the positioning components on both sides of the beam and moving the measuring components on the beam, the measurement of the horizontal and vertical distances of the measuring points of the induction plate is realized, which meets the high-precision requirements of the height installation of the induction plate, improves the accuracy of the elevation control during the installation of the induction plate, improves the construction quality, and reduces the risk of construction rectification; (3) the elevation measurement work of the induction plate is changed from the existing 4-5 people in a group to 1-2 people in a group using special tools to ensure construction efficiency, which reduces the cost of personnel input during the installation of the induction plate, can quickly measure the elevation of the induction plate, reduces the construction process, and improves the efficiency of the installation of the induction plate.

Implementation

[0024] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-Figure 5 As shown, a tool for controlling the elevation of a linear motor induction plate comprises a crossbeam 1 and a measuring assembly 2, wherein the two ends of the crossbeam 1 are respectively provided with a first positioning assembly 11 and a second positioning assembly 12, wherein the measuring assembly 2 comprises a slide 21 slidably mounted on the crossbeam 1 and used to measure the lateral distance of the induction plate measuring point, and a caliper 22 mounted on the slide 21 and used to measure the vertical distance of the induction plate measuring point, as shown in FIG. Figure 6 As shown, a scale 13 for marking the lateral distance is provided on the surface of the crossbeam 1, and the probe of the caliper 22 is arranged perpendicular to the sensing plate. During measurement, the probe contacts the sensing plate 3, and the probe is both a probe for the vertical distance and a probe for the vertical distance. The first positioning component 11 is an adjustable component, and the first positioning component 11 consists of a first positioning plate 111, a first stopper 112 slidably mounted on the first positioning plate 111, and an elastic element 113 mounted between the first positioning plate 111 and the first stopper 112. The second positioning component 12 consists of a second positioning plate 121 and a second stopper 122 fixedly mounted on the second positioning plate 121. Limiting steps 15 for positioning on the rails 4 on both sides of the sensing plate 3 are formed between the first stopper 112 and the first positioning plate 111, and between the second stopper 122 and the second positioning plate 121.

[0026] The crossbeam 1 adopts an aluminum alloy bracket with a length of 1600mm, a width of 30mm, and a height of 35mm, connecting the middle sliding measurement structure and the rail top bases at both ends, so that the entire device becomes a whole and can be conveniently carried and placed during use.

[0027] The first positioning plate 111 and the second positioning plate 121 are arranged on the left and right ends of the beam 1. Since the first stopper 112 is slidably mounted on the first positioning plate 111, the first positioning plate 111 is slightly longer than the second positioning plate 121. In this embodiment, the dimensions of the first positioning plate 111 are 130 mm long, 30 mm wide, and 25 mm high, and the dimensions of the second positioning plate 121 are 110 mm long, 30 mm wide, and 25 mm high. The first positioning plate 111 and the second positioning plate 121 are both made of aluminum alloy, which can connect the upper and lower structures of the tool and raise the beam 1. Since the surface of the induction plate 3 is higher than the rail surface of the rail 4, this structure is set to ensure that the tool is always higher than the induction plate 3 when it is mounted on the rail 4, so as to meet the use conditions.

[0028] The first stopper 112 is an aluminum alloy stopper with a length of 35 mm, a width of 30 mm, and a height of 15 mm. The elastic element 113 is a spring, one end of which is connected to the first positioning plate 111, and the other end is connected to the first stopper 112. During measurement, when the track gauge changes, the elastic element 113 is under tension, and the tool is always in contact with the inner side of the rail head of the rail 4. When not measuring, the elastic element 113 can drive the first stopper 112 to automatically rebound to the outermost side of the beam 1.

[0029] The second stopper 122 is an aluminum alloy stopper with a length of 35 mm, a width of 30 mm, and a height of 15 mm, which is fixed together with the second positioning plate 121. When in use, this stopper is placed on the inner side of the rail 4 as a basis, and the first stopper 112 on the other side is movably adjusted to make the tool perpendicular to the longitudinal direction of the rail 4.

[0030] The cross beam 1 is provided with a first track 14 for the sliding seat 21 to slide, and the first positioning plate 111 is provided with a second track 114 for the sliding of the first stopper 112, and the first track 14 and the second track 114 are arranged in parallel. Figure 7 As shown, the second track 114 is arranged in the first positioning plate 111, the first stopper 112 is provided with a T-shaped block sliding on the second track 114, and the elastic element 113 is arranged between the first stopper 112 and the first positioning plate 111. The slide 21 is a hollow structure with external dimensions of 100 mm in length, 45 mm in width, and 55 mm in height. It can be embedded in the beam 1 and can slide freely along the beam 1, driving the caliper 22 to slide freely on the beam 1 smoothly without obstruction. Since the slide 21 is installed on the beam 1 in the form of an inner sleeve, the cross section of the beam 1 is rectangular. As a preferred embodiment, for the convenience of operation, since the upper surface of the beam 1 is provided with a scale 13, the upper surface of the beam 1 is used as the track surface of the first track 14, and the first track 14 is moved back and forth.

[0031] The bottom surfaces of the first stopper 112 and the second stopper 122 are flush.

[0032] The standard height of the induction plate 3 is 15mm above the rail surface, with an error of +1mm~-2mm. If the beam 1 is in direct contact with the rail 4, only negative errors can be measured. Due to the increase of 35mm in height (the height of the first stopper 112 and the first positioning plate 111), the standard range of the tool is now -15mm~+20mm, which can meet the measurement requirements.

[0033] After the verticality of the present application and the rail 4 is well controlled, since the center of the induction plate 3 needs to coincide with the center of the line, and the panel size of the induction plate 3 is uniformly 360mm, the horizontal distance mark of the scale 13 is used to locate the center line of the induction plate. When measuring the elevation of the induction plate, it is necessary to measure 3 places in the same section, namely the left side, the middle, and the right side, and the measurement point position requires the left and right sides to be 80-100mm away from the center line. When measuring, move the slide 21 to align with the scale of the horizontal distance mark, and the three measuring points can be accurately determined.

[0034] At the same time, compared with the existing construction method, the present application draws on the idea of ​​the existing digital display vernier caliper and installs a digital display electronic caliper on the slide 21. When the measuring scale moves downward to the top surface of the contact sensing plate, the data can be read immediately on the display screen, and the degree of 0.01mm can be displayed.

[0035] The tool is lightweight, easy to carry and convenient to use. The raw materials of the tool are aluminum alloy and PVC, which reduces the use of internal steel and other materials. The overall weight is within 3kg, the price is cheap, and the manufacturing cost is not high.

[0036] When in use, place the application vertically on the rail 4 (position the beam 1 on the rails 4 on both sides through the limit step 15), move the slide 21 laterally along the beam 1, observe the corresponding degree on the scale 13, measure once at the left degree 100mm position, measure once at the degree 0mm position, and measure once at the right degree 100mm position, and record them respectively. When measuring longitudinally, fix the lower end point (measuring point) of the caliper 22 at a position 15mm above the rail surface, and return the caliper 22 to zero. At this time, the digital degree displayed on the caliper 22 is the difference between this position and the design elevation of the sensor plate 3 (15mm above the rail surface). A positive value means that the sensor plate is higher than the design elevation, and a negative value means that the sensor plate is lower than the design elevation. Then perform the measuring point measurement. After locating the measuring point according to the above-mentioned method for determining the sensing plate measuring point, move the slide 21 to be directly above the measuring point, and move the caliper 22 vertically so that the caliper 22 contacts the top surface of the sensing plate 3. At this time, the error value of the sensing plate elevation can be directly seen on the display screen of the caliper 22, and the unit is 0.01mm.

[0037] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
