Description

Technical Field

[0001] This utility model belongs to the technical field of railway ballastless track concrete track slab construction, and in particular relates to a measuring ruler for rough adjustment of track panel frame. Background Technology

[0002] For the construction of concrete track slabs for double-block ballastless tracks, the track panel frame method is adopted. The specific method is as follows: the sleepers are assembled onto two tool rails (the types of tool rails and fasteners should be the same as those in the design) to form a track panel frame. Then the track panel is transported to the pouring point for rough adjustment, the track slab reinforcement is tied, the formwork is installed, the track panel is finely adjusted, and the track slab concrete is poured.

[0003] In track panel construction, to reduce the workload of fine-tuning and accelerate the construction progress, coarse adjustment is performed after the track panels are placed at the pouring point to control the error between the centerline and rail top elevation of the track panels and the design within 5mm. Currently, two methods are used for coarse adjustment of track panels: 1. Coarse adjustment using a coarse adjustment machine: The coarse adjustment of track panels is carried out using a coarse adjustment machine according to the centerline and level benchmark. The coarse adjustment machine is equipped with an automatic calibration instrument and multiple trolleys work in series. It has a high degree of mechanization and high coarse adjustment accuracy. However, the coarse adjustment machine is huge, requires many supporting tools, has a complicated process, low construction efficiency, high equipment cost and fuel consumption, and is not suitable for use in railway tunnels and subway tunnels; 2. Coarse adjustment by ruler measurement: Based on the elevation and support distance measured every 6.5 meters on the side wall of the ditch, a track surface line is marked on the side wall of the ditch with an ink line, and the track panels are coarsely positioned according to the elevation of the inner rail top surface. This coarse adjustment is fast and requires little equipment investment, but its accuracy is low, which increases the workload of subsequent fine adjustment procedures and affects the overall construction progress.

[0020] Figure 2 This is a bottom view of the present invention. Detailed Implementation

[0021] 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.

[0022] like Figure 1-2 As shown, this utility model provides a technical solution: a measuring ruler for coarse adjustment of a track panel frame, comprising: a ruler 1, the bottom of which is flat and has a groove 11 extending along its length; a laser emitting head 2, the laser emitting head 2 being disposed at the bottom of the ruler 1 with its head facing downward for emitting a laser beam downward, and the laser emitting head 2 being located at the center of the length of the ruler 1; a first distance sensor 3, the first distance sensor 3 being disposed at the bottom of the ruler 1 with its head facing downward for measuring the distance between the bottom of the ruler 1 and the top surface of the base; two sliders 12, each slidably connected within the groove 11, and the two sliders 12 being symmetrically arranged on both sides of the laser emitting head 2 with the laser emitting head 2 as the center; and a synchronous transmission assembly. The synchronous transmission assembly is connected to two sliders 12 to enable the two sliders 12 to move synchronously towards or away from each other; the second distance sensor 5 is connected to one of the sliders 12 and is positioned facing the other slider 12 to measure the distance between the two sliders 12; the tilt sensor 6 is mounted on the ruler 1 to measure the tilt angle of the ruler 1 in its length direction; the information processing module 7 and the display screen 8 are electrically connected to the first distance sensor 3, the second distance sensor 5, the tilt sensor 6, and the display screen 8 respectively to receive data measured by the first distance sensor 3, the second distance sensor 5, and the tilt sensor 6, process the data, and then control the display screen 8 to display it.

[0023] During operation, first mark the center line of the base on the top surface of the concrete base. After the rail frame is transported to the pouring point, place the measuring ruler of this utility model on the rail of the rail frame.

[0024] 1. Adjust the two sliders 12 to move synchronously towards each other through the synchronous transmission assembly. When the two sliders 12 are located between the two rails of the rail frame, place the measuring ruler rod 1 perpendicular to the rails of the rail frame on the two rails of the rail frame. Adjust the two sliders 12 to move synchronously away from each other through the synchronous transmission assembly until the two sliders 12 are stuck inside the two rails of the rail frame. Since the laser emitting head 2 is located at the center of the length direction of the measuring rod 1 and the two sliders 12 are symmetrically arranged on both sides of the laser emitting head 2 with the laser emitting head 2 as the center, the laser emitting head 2 is always located at the center between the two rails of the rail frame. Then, the laser emitting head 2 emits a laser beam downwards. Adjust the rail frame to align the laser beam with the center line of the base, thereby realizing the planar position adjustment of the rail frame.

[0025] 2. By measuring the distance between the bottom of the ruler 1 and the top surface of the base through the first distance sensor 3, the elevation of the rail frame can be obtained. The rail frame is adjusted so that the elevation meets the design value, thereby realizing the adjustment of the elevation position of the rail frame.

[0026] 3. The distance between the two sliders 12 is measured by the second distance sensor 5. The sum of the thicknesses of the two sliders 12 can be used to obtain the track gauge of the two rails of the rail frame. The rail frame is adjusted so that the track gauge meets the design value, thereby realizing the track gauge adjustment of the rail frame.

[0027] 4. The tilt angle of the ruler 1 along its length is measured by the tilt sensor 6. The tilt angle is adjusted to zero in the straight section to achieve the horizontal adjustment of the rail frame in the straight section. In the superelevation section, the superelevation value of the two rails of the rail frame can be calculated by the tilt angle and the track gauge of the two rails of the rail frame. The rail frame is adjusted so that the superelevation value meets the design value, thereby achieving the superelevation adjustment of the rail frame in the superelevation section.

[0028] 5. The data measured by the first ranging sensor 3, the second ranging sensor 5, and the tilt sensor 6 are processed by the information processing module 7 and the display screen 8 and then displayed intuitively, making it easy for operators to view and improving work efficiency.

[0029] In the construction of CRTS double-block ballastless track, the measuring ruler of this utility model can detect and display the track gauge, elevation, tilt angle, and superelevation of the two rails of the track frame. It can also emit a laser beam downward through the laser emitter 2, which makes it easier for operators to adjust the track gauge, elevation, tilt angle, superelevation, and centerline position of the track frame. This significantly improves the efficiency of coarse adjustment, effectively shortens the coarse adjustment process time, and greatly improves the accuracy of coarse adjustment. Moreover, this utility model is easy to use and can be easily mastered by operators, reducing the number of operators required.

[0030] Specifically, the information processing module 7 controls the display screen 8 to display the following information: elevation value H, track gauge value K, inclination angle value θ, and superelevation value h.

[0031] Specifically, the information processing module 7 includes a receiving unit, a storage unit, a calculation unit, and an output unit that are electrically connected to each other. The receiving unit is used to acquire the distance value H0 measured by the first distance sensor 3, the distance value K0 measured by the second distance sensor 5, and the tilt angle value θ0 measured by the tilt sensor 6 and feed it back to the calculation unit. The storage unit pre-stores the sum of the thicknesses of the two sliders 12, K1. The calculation unit is used to calculate that the distance value H0 measured by the first distance sensor 3 is equal to the elevation value H of the rail frame (H=H0), the distance value K0 measured by the second distance sensor 5 plus the sum of the thicknesses of the two sliders 12, K1, is equal to the track gauge value K of the two rails of the rail frame (K=K0+K1), the tilt angle value θ0 measured by the tilt sensor 6 is equal to the tilt angle value θ (θ=θ0), and the sine of the tilt angle value θ multiplied by the track gauge value K is equal to the superelevation value h of the rail frame (h=K*sinθ). The output unit is used to send the values ​​calculated by the calculation unit to the display screen 8 for display.

[0032] Furthermore, the information processing module 7 controls the display screen 8 to display content including elevation difference △H, track gauge difference △K, and superelevation difference △h.

[0033] Specifically, the storage unit also pre-stores a preset elevation value H. 预 Preset track gauge value K 预 Preset ultra-high value h 预 The calculation unit is used to calculate the elevation value H minus the preset elevation value H. 预 Equal to the elevation difference △H (△H=HH) 预 ), Track gauge value K minus preset track gauge value K 预 Equal to the gauge difference △K (△K=KK) 预 ), subtract the preset ultra-high value h from the ultra-high value h 预 Equal to the superelevation difference Δh (Δh = hh) 预 By setting the design values ​​(preset elevation value H) for the track panel elevation, track gauge, and superelevation. 预 Preset track gauge value K 预 Preset ultra-high value h 预 The values ​​are pre-stored in the storage unit and calculated by the calculation unit, then directly displayed on the display screen 8 as the elevation difference △H, track gauge difference △K, and superelevation difference △h. Operators only need to adjust the track frame until all the elevation difference △H, track gauge difference △K, and superelevation difference △h displayed on the display screen 8 are 0 or within the allowable deviation range. This eliminates the need for operators to remember the elevation, track gauge, and superelevation of the track frame, making it easy for operators to get started.

[0034] Specifically, the information processing module 7 is a microcontroller.

[0035] Specifically, a through hole is provided on the side wall of the ruler 1 at the center position along its length; the synchronous transmission assembly includes: a handle 41, which is placed outside the ruler 1; two springs 42, which are respectively connected between the two sliders 12 and the end wall of the ruler 1; and two traction lines 43, one end of which is connected to the two sliders 12 respectively, and the other end passes through the through hole and is connected to the handle 41. When the handle 41 is pulled upward, the handle 41 causes the sliders 12 to move synchronously towards each other through the traction lines 43, while stretching the springs 42. When the handle 41 is released, the springs 42 automatically retract, causing the sliders 12 to return to their initial positions, thereby realizing that the two sliders 12 move synchronously towards each other or away from each other, thus keeping the laser emitter 2 in the middle position.

[0036] Furthermore, the synchronous transmission assembly also includes two fixed pulleys 44 disposed inside the ruler 1. The two fixed pulleys 44 are respectively disposed on both sides below the through hole to support the traction line 43 and change the direction of the traction line 43, thereby preventing the traction line 43 from rubbing and breaking at the opening of the through hole, and making the handle 41 pull the traction line 43 more smoothly.

[0037] Furthermore, the measuring rod 1 is equipped with a handle 9 to facilitate the operator in taking the measuring rod.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
