The beam 111 is provided with an ultra-high prism rod 6 at a position right above the nylon wheel 13, and the ultra-high prism rod 6 is provided with an ultra-high prism 7.
The principle of the invention is explained as follows:
In order to ensure the stability of the vehicle body and the authenticity of collected data, the problem that the leveling of a prism is affected due to suspension of wheels when the vehicle body passes through a triangular pit of a track is avoided, a T-shaped frame is adopted in a frame structure, nylon wheels can avoid communication of left and right steel rails, two steel sheave groups on the right side are directly clamped on the steel rails to walk, so that the detection vehicle is prevented from moving left and right to fall down the track, the steel sheave groups on the right front are provided with brake devices, the brake wheels are of normally closed structures, namely, brake shoes are tightly attached to the steel sheaves under the action of left and right spring forces under the stop state of the trolley, so that the braking effect is achieved, when the vehicle is observed, a brake handle is pinched to release the brake shoes to push forwards, and measurement operation can be carried out after the position of an observation point is reached.
The standard track gauge detection frame (mounting bottom plate and the like) is mainly used for overhead and centering of the prism group, can be applied to places such as a common speed railway, an inter-city railway, a subway and a tramcar, and can also be used for primary adjustment of ballastless tracks of a high speed railway so as to reduce the use cost of a fine adjustment trolley. The device can realize the function of plane position measurement and rail surface elevation measurement at the standard rail gauge of the rail, and the main observation position is the inner side edge of the rail, namely the position (1435/2 position) of half of the standard rail gauge. The center line of the prism is always attached to the inner edge of the steel rail through the detection frame, the steel rail is divided into left and right through the three rolling bearings, the base can be clamped on the steel rail to walk, the rolling bearings on the left side of the steel rail are defined as working bearings, the two rolling bearings on the right side of the steel rail are defined as guide bearings, when a detection vehicle walks, the steel rail cannot be quite straight, in order to ensure that the working bearings are always attached to the inner edge of the steel rail to walk, the base must move left and right in the walking process, a working gap of 5mm (namely, the width of the steel rail is 70, the vertical distance between the edges of the left and right bearings is 75) is reserved between the left and right bearings in the manufacturing process, the working gap is always supported on the inner edge of the steel rail to move along with the trolley under the action of spring force, then the joint bearings are installed by taking the edge positions of the working bearings, which are contacted with the steel rail as centers, the lower parts of the prism rod are inserted into the joint bearings through the step shafts, so that the prism rod is overlapped with one half 1435/2 of a theoretical track gauge, when measurement is needed, the prism rod is centered and kept motionless through manual adjustment of the universal support, the prism rod air bubble is enabled to be kept in the middle, the position of the line actual space position can be known through total station measurement, and then the space position of the track is adjusted according to measurement. In order to ensure that the prism can be quickly centered and leveled in any state, a self-lubricating joint bearing is adopted for forced centering, and meanwhile, a prism rod is connected with the joint bearing, so that the centering error is close to 0, the prism leveling is realized by the aid of a universal bracket, the prism is quickly fixed at a plumb position instead of a prism bracket, and the aims of eliminating the prism centering error and quickly leveling are fulfilled by the method. The universal ball bearing is arranged at the middle position of the bottom of the base, and can bear 50KG when horizontally and universally rolling on the steel rail, so that the bottom of the base can be always kept 2mm away from the surface of the steel rail.
The right groove-shaped steel wheel of the frame clamps the steel rail, so that the reference edge is arranged on the inner side of the right steel rail. The distance between the inner sides of the left steel rail and the right steel rail is measured, and the distance is measured through the two electric insulation bearings which are always propped against the inner sides of the steel rails and rotate, so that the left rail and the right rail are kept insulated while the distance is measured, the electric insulation bearings are respectively fixed at two ends of the two racks, the gear is arranged at the center of the bottom plate, and the two racks are symmetrically distributed in the mounting grooves at two sides of the gear. When the track gauge changes in the running process of the trolley, the racks are lengthened or shortened simultaneously under the action of the spring force at the rear ends of the racks through the gears, and because the reference edge is a right steel rail, the bottom plate can move left and right simultaneously when the length of the racks changes, the moving value is a total extension value or a total shortening value minus half of the standard track gauge, and because the actual track gauge change amount is small, the distance measuring scale is set to be +/-30 mm, namely the effective measuring range is between 1405 and 1465, so that when the trolley is detected to run at any position on the track, the moment reading can be carried out according to the scale position indicated on the racks. When the rack is used on a wide rail or a narrow rail, the length of the rack can be increased or reduced correspondingly. Among the four aluminum alloy supporting frames, the middle two are used for the connection of the bottom plate and the frame bolt, and the upper two are used for the connection of the rack and the frame bolt. Because the gauge measuring ruler moves continuously left and right in operation, in order to reduce the power loss of the spring, aluminum alloy materials are adopted as much as possible, the aluminum alloy materials are hollowed out and light, and all sliding surfaces are used for reducing friction resistance and limiting, steel balls or rolling pins are adopted, and rolling friction is used for replacing sliding friction.
The pressing block is fixed right above the middle gear of the bottom plate of the track gauge measuring ruler, a pair of equal and opposite force is applied to the ranging racks through the middle gear under the action of the spring, so that the racks on two sides can be caused to stretch out and draw back simultaneously, the prism is always positioned at the right and left rail centers when the track gauge is measured, the problem of centering the prism is solved, then the prism rod is manually adjusted to center the bubble, the prism rod can keep the vertical position under the friction braking of the spherical hinge of the universal support, at the moment, the line center space position measurement can be carried out by the total station, and then the space position adjustment of the track is carried out according to the measured value. Because the measured position is at the center of the line, the bottom of the prism rod of the normal road section coincides with the rail surface, the measured elevation data is directly adopted, when the height of the rail surface is measured at the ultrahigh road section, the prism height is half of the actual measurement ultrahigh value added and subtracted by the length of the prism, for example, the left side is ultrahigh, the elevation of the rail surface of the low rail is half of the actual measurement elevation value minus the ultrahigh value, and the elevation of the rail surface of the high rail is half of the ultrahigh value of the height Cheng Zhijia. Since the rotation center of the universal ball support has a height of 20 mm from the rail surface, the centering error is 0 when the universal ball support is on a straight line road section, the corresponding angle value of the ultra-high limit value 150/1505 is 5.692 degrees according to the cotangent formula when the universal ball support is on a curve road section, the centering error is 1.993 mm in the ultra-high limit state according to the tangent formula when tan5.692 DEG=centering error/20, and the centering error is 0.664 mm when the universal ball support is on a curve road section, and according to most of current railway design speed per hour and curve radius data, the ultra-high value of most of railways is within 50mm according to the ultra-high calculation formula h=7.6Vmax 2/R, so that the centering error caused on the curve road section is 0.664 mm.
The dial plate of the ultrahigh detector adopts an aluminum plate with the diameter of 100 mm and the thickness of 1 mm, and for convenient reading, a forward reverse full-circle digital mark (namely 360 degrees are marked by forward rotation and 360 degrees are marked by reverse rotation) is adopted, the dial plate sleeve is fixed on the support plate by clamping the annular groove through two transverse bolts, and the dial plate is adhered to the dial plate sleeve through a strong adhesive, so that the dial plate can be randomly rotated along with the dial plate sleeve to realize 360 degrees. The balance weight is formed by cutting a 10mm thick hot rolled steel plate into double kidney shapes by adopting a laser line, and the surface of the steel plate is blackened, so that the balance weight can accurately level in reading, and horizontal bubbles are arranged on the balance weight. The support plates were cut from a 16 mm thick 6061 aluminum plate and connected by M6 bolts for weight saving while ensuring strength. In order to reduce working resistance and ensure good working state, 606ZZ type high-speed rolling bearings are arranged at two ends of each connecting shaft of the gearbox, 6 high-speed rolling bearings are arranged on a gearbox supporting plate in an interference fit manner, and all aluminum plates are connected through M6 bolts.
The working principle of the ultra-high detector is that the ultra-high value of a railway track is generally 0-150 mm, the horizontal distance is corresponding to 1505 mm (standard track gauge 1435+rail width 70), when a detecting vehicle passes through a curve section, the outer rail is lifted up to cause the vehicle body to transversely rotate by one angle, the calculated angle value is very small and insensitive as known by a tangent formula tana = ultra-high value/rail center distance 1505, if the rotating angle is directly indicated by the dead weight of a lifting hammer, the actual ultra-high value needs to be calculated according to a rotating angle value sleeve formula, time and labor are wasted, and in order to directly adopt a standard 360-degree dial to display the ultra-high value according to 1:1 (each rotation of a pointer is equal to one mm in the distance direction, namely, the ultra-high of 1 mm), then the numerical value is amplified through a left balance block, a right balance block and a gearbox. Firstly, performing simulation calculation, drawing a straight line with the length of 1505 millimeters and an angle of 1 degree along one end of the straight line as an endpoint, then, through marking the width of an opening as 26.27 millimeters, finally, performing calculation by a calculator, verifying that tan1 degree=ultrahigh value/1505 is calculated, and the calculated ultrahigh value is 26.27 millimeters, so that when the vehicle body rotates by 1 degree, the corresponding ultrahigh value is 26.27 millimeters, a two-stage gearbox is designed based on the calculated ultrahigh value, the two-stage gear ratios are respectively 20:100 and 20:105.08, and the speed ratio is finally 1:26.5, and the corresponding tooth number is 20:100 and 20:106. Because the ultra-high detector is designed according to the standard gauge 1435 mm, when a wide gauge or a narrow gauge is adopted, the acceleration ratio needs to be calculated again, the speed ratio is matched again, and the calculation principle is the same as that of the ultra-high detector. The ultra-high detector is detachable, so that the calibration is carried out before each use, the calibration method is to firstly measure the elevation of the left rail surface of the same mileage by utilizing the prism group on the nylon wheel, then rotate the vehicle body for 180 degrees to measure the elevation of the right rail surface, namely the ultra-high value, the elevation difference of the two rail surfaces can be arbitrarily rotated by 360 degrees, and therefore, the scale disc can be rotated to the ultra-high value indicated by the pointer only after the balance weight is kept horizontal. In order to adapt to the convention and facilitate the reading, the 0 scale of the pointer is oriented to the right lower side or the right upper side as much as possible during the adjustment, if the difference is too large, the pointer is oriented to the right upper side or the right lower side only by rotating the balance weight, then the bolt on the adjustment balance weight is loosened, and the bolt is screwed after the balance weight is rotated to be horizontal. because the ultrahigh detector is sensitive, slightly activity influence can enlarge 26.27 times through the gearbox, and the adverse factors such as friction resistance in the gearbox, the counter weight windward side is great in the use, vibrations are produced when walking are considered, can cause counter weight self-balancing reset error to lead to showing numerical value inaccurate, so the horizontal bubble on the counter weight is particularly noted whether centering when reading at every time, if not centering, the counter weight is manually turned down, and the bubble just can accurate reading when centering, because the calibrated scale is two-way 360 degrees demonstration, the pointer rotation direction reading should be followed in the time of the reading (generally left ultrahigh pointer anticlockwise rotation, right ultrahigh pointer clockwise rotation). The ballastless track has more tamping times, the ultra-high detector can be used for verifying the ultra-high in the previous times, the prism is used for measuring in the fine adjustment stage, the prism is used for measuring in the ultra-high uniformity in the coarse adjustment stage of the ballastless track, and the jack of the ultra-high measuring prism is arranged right above the middle of the nylon wheel.
In track initial setting, in order to be able to directly show that the super high value is convenient and theoretical value compares, this detects the car and has adopted gravity balance formula machinery pointer to show, the track detects the car and can raise through curve section outside track, lead to the automobile body to rotate an angle, because super high value is little for track gauge direction contained angle, so automobile body rotation angle is also not big, in order to make super high value 1:1 show through balancing piece and gearbox, finally realize through gearbox enlarge the angle value that the pointer just equals one millimeter in every rotation direction, just so the angle value that causes super high converts length direction's millimeter value. Because the circumference is 360 degrees, the measurement range of the trolley is-360 millimeters in theory, and the ultra-high value of railway design is generally within 150 millimeters, so that the trolley can completely meet the actual requirements. When the trolley passes through a curve section, the trolley body rotates left and right and the balance weight is always horizontal, so that a pointer on the trolley body is driven to rotate clockwise or anticlockwise, the aim of displaying an actual ultrahigh value is fulfilled, and when the track enters a fine adjustment stage, the ultrahigh track height can be measured only by inserting a prism group above a left nylon wheel for absolute height measurement.
