Description

Technical Field

[0001] The utility model relates to the technical field of measuring devices, in particular to a double-track railway mileage measuring device. Background Technique

[0002] Railway tracks, also known as road tracks, railway tracks, tracks, etc., are mainly used on railways and cooperate with switches to enable trains to travel without turning. Railway tracks usually consist of two parallel steel rails, which are fixed on sleepers, and road ballast is placed under the sleepers. Fastened by railway accessories such as rail braces, fasteners, rail clamps, rail splints, spring clips, and railway spikes, track measurement technology refers to a technology that determines the geometric parameters, position, and deformation of the track by measuring the relative position between the wheels and the track.

[0003] First, at present, for railway track mileage measurement, a measuring device is used to measure a single-sided track. However, there are curved sections on the track, and there will be a difference in the left and right mileage of the curved sections. Only measuring one side will cause errors in the measurement results and low accuracy. At the same time, the existing measurement method is to manually push the device to move on the track, which is not only time-consuming and laborious, but also has low measurement efficiency.

[0004] Second, before measurement, a computer for controlling data is placed on the support rod of the measuring device. The existing support rods are all made of metal and cannot be effectively fixed when contacting the smooth bottom of the computer. At the same time, since the support rod extends from the telescopic rod, the bottom of the extended part of the support rod is suspended and will deform when subjected to the pressure of the computer, resulting in unstable placement of the computer when the device moves. Content of the Utility Model

[0005] The purpose of the utility model is to provide a double-track railway mileage measuring device to solve the problems raised in the above background technique.

[0006] To solve the above technical problems, the utility model provides the following technical solution: A double-track railway mileage measuring device, including a device main body; driving wheels located on both sides of the device main body, the driving wheels are used to drive the device main body to move; a support rod located on the top of the device main body, the support rod is used to support the support rod; rollers are rotatably connected to both sides of the device main body, the bottom of the rollers is closely attached to the track main body, one side of the rollers close to the device main body is connected to an encoder through a coupling, the encoder is bolted to both sides of the device main body, a protective shell is bolted to the bottom of the device main body, a rotary motor is bolted inside the protective shell, there are two rotary motors, the driving wheels are located on the sides away from each other of the two rotary motors, a damping block is bolted to the outside of the driving wheels, a telescopic rod is clamped on the top of the device main body, and the support rod is located on both sides of the top of the telescopic rod.

[0007] Preferably, a drive shaft is bolted to the bottom output end of the rotary motor. A belt is wrapped around the outside of the drive shaft. One end of the belt away from the drive shaft is wrapped around a positioning rod, and the positioning rod fixedly penetrates through the drive wheel.

[0008] Preferably, an activity groove is formed on one side of the protective housing close to the belt. The drive shaft is rotatably connected in the activity groove, and the belt penetrates through the activity groove.

[0009] Preferably, a fixing plate is bolted to one side of the protective housing close to the drive wheel. The fixing plate is located on both the upper and lower sides of the activity groove, and the upper and lower ends of the positioning rod are movably fitted between the fixing plates.

[0010] Preferably, a plurality of damping blocks are provided, and the plurality of damping blocks are annularly and equidistantly distributed on the surface of the drive wheel. The damping block away from the protective housing abuts against the inner side of the track body.

[0011] Preferably, an adapter ring is bolted to the telescopic rod. The support rods are bolted to both sides of the adapter ring, and one end of the support rod is bolted to the top of the telescopic rod.

[0012] Preferably, the top of the support rod closely abuts against the bottom of the support rod. An anti-slip block is bolted to one side of the support rod away from the support rod.

[0013] Compared with the prior art, the beneficial effects achieved by the present utility model are as follows:

[0014] First, start the rotary motor to drive the drive shaft to move the belt. Then, the positioning rod covered by the other end of the belt rotates between the two fixing plates, driving the drive wheel to rotate. Since the damping block is in close contact with the inner side of the track body, the drive wheel will drive the device body to slide uniformly on the track body when rotating. At this time, the rollers on both sides of the device body rotate on the top of the track body, and the encoder records the rotation speed and the number of turns, thereby measuring the track body. High-precision encoders are installed on the rollers on both sides of the device body to synchronize the encoder signals and measure the mileage information of the left and right tracks at the same time. The measurement accuracy can reach 0.3‰, greatly improving the measurement accuracy, and reducing the manual output in cooperation with the drive wheel, improving the measurement efficiency.

[0015] Second, place the computer for control testing above the support rod. When the computer is placed, the anti-slip block will increase the friction between the bottom of the computer and the top of the support rod, preventing the computer from sliding. The support rod can improve the supporting force of the support rod, making the computer placed more stably during the movement process, improving the stability of the device during movement.

When the rotary motor 7 is started, the driving shaft 8 drives the belt 9 to move, and then the positioning rod 10 covered by the other end of the belt 9 rotates between the two fixing plates 6, driving the driving wheel 11 to rotate. Since the damping block 12 is closely attached to the inner side of the rail main body 13, the driving wheel 11 will drive the device main body 1 to slide uniformly on the rail main body 13 when rotating. At this time, the roller wheels 2 on both sides of the device main body 1 rotate on the top of the rail main body 13, and the encoder 3 records the rotation speed and the number of turns, thereby measuring the rail main body 13. By installing a high-precision encoder 3, synchronizing the encoder 3 signal, and simultaneously measuring the mileage information of the left and right rails, the measurement accuracy can reach 0.3‰, greatly improving the measurement accuracy, and reducing the manual output in cooperation with the driving wheels 11, improving the measurement efficiency.

[0023] Specifically, the bottom output end of the rotary motor 7 is bolted to a driving shaft 8, a belt 9 is wrapped around the outside of the driving shaft 8, and one end of the belt 9 away from the driving shaft 8 is wrapped around a positioning rod 10, and the positioning rod 10 fixedly penetrates through the driving wheel 11.

[0024] Through the above technical solution, the belt 9 will be driven to move by the rotating driving shaft 8, and then drive the positioning rod 10 to rotate.

[0025] Specifically, a movable groove 5 is opened on one side of the protective shell 4 close to the belt 9, the driving shaft 8 is rotatably connected in the movable groove 5, and the belt 9 penetrates through the movable groove 5.

[0026] Through the above technical solution, the movable groove 5 provides space for the movement of the belt 9.

[0027] Specifically, fixing plates 6 are bolted to one side of the protective shell 4 close to the driving wheels 11, the fixing plates 6 are located on the upper and lower sides of the movable groove 5, and the upper and lower ends of the positioning rod 10 are movably fitted between the fixing plates 6.

[0028] Through the above technical solution, the fixing plates 6 provide a stress point for the positioning rod 10.

[0029] Specifically, a plurality of damping blocks 12 are provided, and the plurality of damping blocks 12 are evenly distributed in a ring on the surface of the driving wheel 11, and the damping blocks 12 far from the protective shell 4 abut against the inner side of the track body 13.

[0030] Through the above technical solution, the damping block 12 is made of rubber. When the damping block 12 contacts the track body 13, a strong frictional force will be generated between the two. As the damping block 12 rotates continuously, the device body 1 can be driven to move above the track body 13 through the frictional force.

[0031] Specifically, an adapter ring 15 is bolted to the telescopic rod 14, and support rods 16 are bolted to both sides of the adapter ring 15, and one end of the support rod 17 is bolted to the top of the telescopic rod 14.

[0035] During use, the device body 1 is placed above the two track bodies 13, so that the rollers 2 are in close contact with the top of the track body 13, and some of the damping blocks 12 on the driving wheel 11 are in close contact with the inner side of the track body 13. Then, the telescopic rod 14 is clamped on the device body 1, and the computer for controlling the test is placed above the support rod 17. When the computer is placed, the anti-slip block 18 will increase the frictional force between the bottom of the computer and the top of the support rod 17 to prevent the computer from sliding. The support rod 16 can improve the supporting force of the support rod 17, so that the computer is placed more stably during the movement. By turning on the rotary motor 7 through an external control terminal, the drive shaft 8 drives the belt 9 to move, and then the positioning rod 10 covered by the other end of the belt 9 rotates between the two fixing plates 6, driving the driving wheel 11 to rotate. Since the damping block 12 is in close contact with the inner side of the track body 13, the driving wheel 11 will drive the device body 1 to slide uniformly on the track body 13 when rotating. At this time, the rollers 2 on both sides of the device body 1 rotate on the top of the track body 13, and the encoder 3 records the rotational speed and the number of turns, thereby measuring the track body 13.
