The principle of the utility model is illustrated as follows:

in order to ensure the stability of the vehicle body and the authenticity of acquired data and avoid the problem that the leveling of the prism is influenced by the suspension of wheels when the vehicle body passes through a triangular pit of a track, a T-shaped vehicle frame is adopted as a vehicle frame structure; the nylon wheel can prevent the left and right steel rails from being communicated, the two steel grooved wheel sets on the right side are directly clamped on the steel rails to walk, the detection vehicle is prevented from moving left and right to fall off the rail, the steel grooved wheel set on the front right is provided with a brake device, the brake wheel is of a normally closed structure, and the brake shoe is tightly attached to the steel grooved wheel under the action of left and right spring forces when the trolley is stopped, so that the brake effect is achieved; when the observation is finished and the user needs to walk forwards, the user can push forwards by holding the brake handle and loosening the brake shoe, and the user can perform measurement operation by loosening the brake handle after reaching the observation point.

The design can be applied to places such as ordinary speed railways, intercity railways, subways, trams and the like, and can also be used for primary adjustment of ballastless tracks of high-speed railways to reduce the use cost of the fine adjustment trolley. The functions of measuring the plane position of the rail, measuring the elevation of the rail surface, measuring the height of a curve and measuring the track gauge can be realized, and the main observation position is the central line of the steel rail (752.5 mm away from the center of the track, namely 1435/2+ 70/2). In order to ensure that the prism can be centered and leveled quickly in any state, the detection vehicle adopts a self-lubricating joint bearing to perform forced centering, and simultaneously designs and manufactures a special prism rod connected with the joint bearing, so that the centering error is ensured to be close to 0, the prism leveling is realized by the aid of a universal support, the prism can be quickly fixed at the position of a plumb bob by replacing a prism support, and the aims of eliminating the prism centering error and quickly leveling are fulfilled by the method. Because the steel sheave is directly blocked and is walked on the rail, the longitudinal central point of steel sheave puts the position at rail center promptly, this detection car is established the right front wheel as the working wheel, install self-lubricating joint bearing in the well place ahead of working wheel, the prism center has just coincided with the rail center like this, the prism pole needs to replace the conical head of bottom threaded step shaft connector, little prism group or big prism group are connected to the connector for the joint bearing, the prism group is all leveled fast and keep the spatial position through universal bracket, at this moment, combine the total powerstation just can carry out rail center spatial position and measure, then carry out orbital spatial position according to the measured valueAnd (5) adjusting. Because the measured position is in the center of the steel rail, normal measurement operation can be hindered due to the fact that the prism rod directly slides on the steel rail, in order to guarantee accuracy of collected elevation data, the prism rod is overhead at the bottom, namely, the bottom cone head of the prism rod is shortened by 10 millimeters under the condition that the position of the top of the prism is not changed, and then overhead is achieved through the threaded stepped shaft connector. The height of the rotation center of the self-lubricating knuckle bearing from the rail surface is 10 millimeters, so that the centering error is 0 in a straight line section, the angle value corresponding to the ultra-high limit value 150/1505 is 5.692 degrees according to the cotangent formula in a curve section, the centering error is 0.997 millimeters in an ultra-high limit state when tan5.692 degrees is equal to centering error/10 according to the tangent formula, and the ultra-high calculation formula h is equal to 7.6Vmax according to the time speed and curve radius data of most of the existing railway design²the/R shows that most railway super-high values are within 50 mm, so that the centering error caused by most curve sections is 0.332 mm.

The groove-shaped steel wheel on the right side of the frame is clamped on the steel rail, so that the reference edge is arranged on the inner side of the right steel rail. The distance between the left rail and the right rail is measured by measuring the distance between the inner sides of the left rail and the right rail, and the left rail and the right rail can be kept insulated by two electrically insulated bearings which are always supported on the inner sides of the rails to rotate, so that the distance can be measured, the electrically insulated bearings are respectively fixed at two ends of two racks, the gear is arranged in the center of the bottom plate, and the two racks are symmetrically distributed in mounting grooves at two sides of the gear. When the gauge changes in the dolly walking process, make the rack lengthen simultaneously or shorten simultaneously through the gear under the spring force effect of rack rear end, because the reference edge is on the right side steel rail, so the bottom plate can remove about simultaneously when rack length changes, the removal value is half behind the total extension or total shortening value subtraction standard gauge, because the actual gauge change volume is little, so this range finding telescopic stroke is set for to this range finding chi is 30 millimeters, effective range finding is between 1405 to 1465 promptly, when the detection car walks on the track optional position, can both be according to the instantaneous reading of scale position that indicates on the rack like this. When the gear rack is used on a wide rail or a narrow rail, the gear rack can be used only by correspondingly increasing or reducing the length of the gear rack. Among four aluminum alloy support frames, two in the middle are used for bottom plate and frame bolted connection, and two on the edge are used for rack and frame bolted connection. Because the track gauge measuring ruler is continuously moved left and right in the work, in order to reduce the power loss of the spring, aluminum alloy materials are adopted as much as possible and hollowed out for lightening treatment, all sliding surfaces are used for reducing friction resistance and limiting, steel balls or rolling needles are adopted, and sliding friction is replaced by rolling friction.

Fix the briquetting directly over gauge dipperstick bottom plate intermediate gear, because the range finding rack can apply a pair of size through intermediate gear under the spring action and equal, opposite direction's power, will arouse both sides rack to stretch out and draw back simultaneously, just so guaranteed that the prism also is in right track centre of the left and right sides all the time when carrying out gauge measurement, thereby solved prism centering problem, then make the bubble placed in the middle through manual regulation prism pole, prism pole will keep vertical position under universal support ball pivot frictional force braking, at this moment just can carry out circuit center spatial position with the total powerstation and measure, then carry out orbital spatial position adjustment according to the measured value. The measured position is in the center of the line, the bottom of the prism rod of the normal road section is coincident with the rail surface, so the measured elevation data is directly adopted, when the height of the rail surface is measured on the ultrahigh road section, the height of the prism is the length of the prism plus or minus half of the actually measured ultrahigh value, for example, the left side is ultrahigh, then the elevation of the low rail surface is the height of the actually measured elevation value plus or minus half of the ultrahigh value, and the elevation of the high rail surface is the height of the actually measured elevation value plus or minus half of the ultrahigh value. The height of the rotation center of the universal ball support is 20 mm from the rail surface, so that the centering error is 0 in a straight line section, the angle value corresponding to the ultrahigh limit value 150/1505 is 5.692 degrees according to the cotangent formula in a curve section, the centering error/20 in tan5.692 degrees is calculated according to the tangent formula, the centering error in the ultrahigh limit state is 1.993 mm, and according to the time speed and curve radius data of most of the existing railway design, the ultrahigh calculation formula h is 7.6Vmax²the/R shows that most railway super-high values are within 50 mm, so that the centering error caused by the curve section is 0.664 mm.

The dial plate adopts the diameter to be 100 millimeters thick 1 millimeter's aluminium dish in the super high detector, for making things convenient for the reading, adopts positive reverse full circle digital sign (360 degrees are marked in the forward rotation promptly, 360 degrees are marked in the reverse rotation), and the dial plate cover blocks the ring channel through two transverse bolt and fixes in the backup pad, and the calibrated scale passes through the powerful glue and bonds with the dial plate cover, and the calibrated scale just can realize 360 arbitrary rotations along with the dial plate cover like this. The counterbalance is cut into double kidney shape by 10 mm thick hot rolled steel plate by laser line, the surface of the steel plate is blackened, and horizontal air bubbles are arranged on the counterbalance to ensure that the counterbalance can be accurately leveled during reading. The support plates were cut with a 16 mm thick 6061 aluminum plate and bolted together using M6 bolts to provide strength while reducing weight. The gearbox adopts two-stage speed reduction, and the gear module is 0.5; in order to reduce the working resistance and ensure a good working state, two ends of each connecting shaft of the gearbox are provided with 606ZZ type high-speed rolling bearings, the number of the high-speed rolling bearings is totally 6, the high-speed rolling bearings are arranged on a supporting plate of the gearbox in an interference fit manner, and all aluminum plates are connected through M6 bolts.

The working principle of the ultrahigh detector is as follows: the ultrahigh value of the railway track is generally between 0 and 150 mm, the corresponding horizontal distance is 1505 mm (standard track gauge 1435+ steel rail width 70), when the detection vehicle passes through a curve section, the lifting of the outer steel rail can cause the transverse rotation of the vehicle body by an angle, the tangent formula tana is the ultrahigh value/steel rail center distance 1505, the calculated angle value is very small, and the reaction is insensitive; if the rotating angle is directly indicated by the deadweight of the hanging hammer, the actual ultrahigh value needs to be known, calculation is needed according to a rotating angle value set formula, time and labor are wasted, and the method is very troublesome, and in order to directly adopt a standard 360-degree dial according to the formula 1: 1, displaying the ultrahigh value (the pointer is equal to one millimeter in the distance direction once rotating once every second time, namely the ultrahigh value is 1 millimeter), and then carrying out numerical amplification through a left balance block, a right balance block and a gearbox. Firstly, carrying out simulation calculation, drawing a straight line which is 1505 mm long, drawing a straight line which is 1 degree in length and is 1505 mm in angle along one end of the straight line as an end point, marking the width of an opening to be 26.27 mm, and finally calculating and verifying tan1 degrees as an ultrahigh value/1505 through a calculator to obtain the ultrahigh value which is 26.27 mm, so that the corresponding ultrahigh value is 26.27 mm when the vehicle body rotates for 1 degree, and designing a two-stage gearbox by taking the ultrahigh value as a reference, wherein the two-stage gear ratios are respectively 20:100 and 20:105.08, the power loss and the gear processing are convenient, the acceleration ratio is 1:26.5, and the corresponding tooth numbers are 20:100 and 20: 35106; when the dolly passes through the curve highway section, the automobile body is rotatory and the balancing piece remains the horizontality throughout, just so drives the dial plate through the automobile body rotation and follows the automobile body clockwise or anticlockwise rotation, and pointer two-pass gearbox also can follow the rotation with higher speed, and the gearbox just so converts the angle value to the millimeter value and has just realized showing the purpose of actual superelevation value. Because the ultrahigh detector is designed according to the standard track gauge 1435 mm, when a wide track or a narrow track is adopted, the acceleration ratio needs to be recalculated and matched again, and the calculation principle is the same. The ultrahigh detector is detachable, so that calibration is required before use every time, the calibration method is to utilize the prism group on the nylon wheel to measure the elevation of the left rail surface of the same mileage at first, then the elevation of the right rail surface is measured by rotating the vehicle body for 180 degrees, the elevation difference of the two rail surfaces is the ultrahigh value, the dial of the detector can be rotated at will for 360 degrees, and the dial can be rotated to the ultrahigh value indicated by the pointer II after the balance block is kept horizontal. In order to adapt to the common practice and facilitate reading, the scale 0 of the second pointer is enabled to face right below or right above during adjustment, if the difference is too much, the second pointer is enabled to face right above or right below by rotating the balance block, then the bolt on the balance block is loosened, and the balance block is rotated to be horizontal and then the bolt is screwed down. Because the ultrahigh detector is sensitive to reaction, the slight movement influence can be amplified by 26.27 times through the gearbox, the influence of adverse factors such as the friction resistance inside the gearbox in the use process, the windward side of the balance weight is large, vibration is generated during walking and the like is considered, the display numerical value is inaccurate due to the self-balancing reset error of the balance weight, whether horizontal bubbles on the balance weight are centered is particularly noticed during each reading, if the horizontal bubbles are not centered, the balance weight is manually rotated once, accurate reading can be realized when the horizontal bubbles are centered, and the reading is carried out along the rotating direction of the pointer II (generally, the left ultrahigh pointer II rotates anticlockwise, and the right ultrahigh pointer II rotates clockwise) because the dial is displayed in a two-way 360 degrees. The ballasted track has more tamping passes due to the large machine, the superelevation can be verified by the superelevation detector for the first several times, the ballasted track enters a fine adjustment stage and is measured by the prism, the superelevation of the ballastless track in a coarse adjustment stage is uniformly measured by the prism, and the superelevation measuring prism jack is positioned right above the middle of the nylon wheel.

In the track is just transferred, in order to can direct indication super high value convenience and theoretical value contrast, this detection car has adopted two demonstration of gravity balance formula machinery pointer, and the track is examined the car and can be raised through curve section outside track, leads to the automobile body can rotatory an angle, because super high value is little for gauge direction contained angle, so automobile body rotation angle is also not big, in order to make super high value 1 through balancing piece and gearbox: 1, finally, the angle value is amplified through the gearbox to realize that the pointer is equal to one millimeter in the height direction every time the pointer rotates once, so that the angle value caused by the superelevation is converted into a millimeter value in the length direction. Because the circumference is 360 degrees, the measuring range of the trolley is-360 mm theoretically, and the ultrahigh value of the railway design is generally within 150 mm, so that the actual requirement can be completely met. When the trolley passes through a curve road section, the trolley body rotates left and right, and the balance block is always horizontal, so that the pointer II on the trolley body is driven to rotate clockwise or anticlockwise, and the purpose of displaying the actual ultrahigh value is achieved; when the track enters a fine adjustment stage, the height of the ultrahigh track can be measured only by inserting the prism group above the nylon wheel on the left side to measure the absolute height.
