Description

Technical Field

[0001] The utility model relates to the technical field of track inspection instruments, in particular to a fast-measuring track inspection instrument. Background Art

[0002] A track inspection instrument is a detection instrument specifically used for measuring and analyzing the internal geometric parameters of a track, and can accurately detect parameters such as gauge, superelevation, level, alignment, irregularity, chord offset, twist (triangle depression), and gauge change rate. The use of an integral frame design, high-precision imported sensors, and a more perfect analysis model ensures the accuracy of the measurement data. When in use, the track inspection instrument is placed on the track, and the track inspection instrument is manually pushed to walk on the track at a speed of about 5 km / h to complete the measurement of the track geometric parameters. According to the requirements of the Railway Industry Standard TB / T 3147-2020 "Railway Track Inspection Instrument" of the People's Republic of China, the detection and pushing speed of the track inspection instrument shall not be greater than 8 km / h, and the actual on-line manual pushing detection speed is generally about 5 km / h, and the detection speed is relatively slow. Secondly, when the pushing speed of the existing track inspection instrument is greater than 8 km / h, the error of its detection data will increase and cannot meet the accuracy requirements. Moreover, it is difficult for people to maintain a constant speed during pushing, and the greater the speed, the greater the impact, which will also increase the measurement error. After the pushing speed of the track inspection instrument is increased, the track inspection instrument is very likely to derail and cause damage to the instrument. Content of the Utility Model

[0022] Such as Figures 1 to 5As shown in the figure, a fast measurement type track inspection instrument includes a traction device 100 and a body 200, and further includes a quick connection component 1, an anti-derailment component 2, running wheels 3 and measuring wheels 4. One end of the quick connection component 1 is detachably connected to the traction device 100, and the other end is connected to the body 200. The anti-derailment component 2 includes a locking clip 21, a plug 22 and a pressure contact member 23. One end of the pressure contact member 23 is detachably connected to the locking clip 21 through the plug 22. The locking clip 21 is connected to the traction device 100. The other end of the pressure contact member 23 is pressed against the upper end surface of the body 200. The running wheels 3 and the measuring wheels 4 are both installed below the body 200. The running wheels 3 are in contact with the rail surface of the track 300, and the measuring wheels 4 are in contact with the side wall of the track. Specifically, in this embodiment, the traction device 100 is used to guide the body 200 of the track inspection instrument to travel on the track 300, and it can move quickly (12 km / h) on the track and ensure a uniform speed. By connecting the body 200 and the traction device 100 through the quick connection component 1, the speed is ensured to be stable, and it is convenient to disassemble the track inspection instrument from the traction device 100. The running wheels 3 are installed below the body 200 and are in contact with the rail surface of the track 300, while the measuring wheels 4 are arranged below the body 200 and are used to contact the inner wall of the track 300. In order to prevent the track inspection instrument from derailing due to vibration when passing through uneven rail surfaces such as turnouts quickly, we also designed a set of anti-derailment components 2, including a locking clip 21, a plug 22 and a pressure contact member 23. The pressure contact member 23 is movably pressed against the body 200 and is connected to the locking clip 21 through the plug 22. The locking clip 21 is arranged on the traction device 100. The existence of the pressure contact member 23 can apply a certain pressure to the body 200, so that the track inspection instrument will not jump off the track during travel, nor will the travel resistance of the running wheels 3 of the track inspection instrument be increased due to excessive pressure.

[0023] As Figure 3As shown, the pressing member 23 includes a pressing rod 231, a mounting base 232, a compression spring sleeve 233, a compression spring guide shaft 234, a compression spring 235, a limit sleeve 236 and a ball 237. One end of the pressing rod 231 is detachably connected to the locking clip 21 through a plug 22, and the other end of the pressing rod 231 is connected to the mounting base 232. The compression spring sleeve 233 is vertically arranged in the mounting base 232. The compression spring guide shaft 234 penetrates through the compression spring sleeve 233. The compression spring 235 is arranged in the compression spring sleeve 233 and sleeved on the compression spring guide shaft 234. Both ends of the compression spring 235 are respectively abutted against the upper inner wall and the lower inner wall of the compression spring sleeve 233. The limit sleeve 236 is connected to the lower end of the compression spring guide shaft 234. The ball 237 is movably clamped inside the lower end of the limit sleeve 236. Specifically, in this embodiment, the front end of the pressing rod 231 is connected to the plug 22, and the rear end is welded to the mounting base 232. The cross-section of the mounting base 232 is U-shaped. The compression spring sleeve 233 is vertically installed in the mounting base 232. The compression spring guide shaft 234 penetrates through the compression spring sleeve 233, and its lower end extends out of the compression spring sleeve 233 and is connected to the limit sleeve 236. The ball 237 is movably installed at the lower end of the limit sleeve 236. When in use, the traction device 100 is pulled by the quick connection assembly 1 and travels on the track. At this time, the pressure of the ball 237 acts on the end face of the machine body 200. Because it is rolling friction, the friction coefficient is low, and it will not cause wear to the contact part of the machine body 200. And due to the existence of the compression spring 235, when the track inspection instrument moves on the track and is affected by vibration and cockscomb jumping, the vibration is absorbed by the compression spring 235, playing a shock absorption role, and ensuring a certain pressure so that the track inspection instrument will not jump off the track or derail during the traveling process, nor will it increase the running resistance of the track inspection instrument due to excessive pressure.

[0024] As Figure 3 shown, rubber sleeves 2331 are wrapped around the outer sides of the upper and lower ends of the compression spring sleeve 233, and the rubber sleeves 2331 are abutted against the inner side of the mounting base 232. Specifically, the rubber sleeves 2331 play a buffering role to prevent hard contact between the two ends of the compression spring sleeve 233 and the inner side of the mounting base 232, and cooperate with the compression spring 235 for shock absorption.

[0025] As Figure 4As shown in the figure, the quick-connection component 1 includes a connection base 11, a connecting rod 12, a connection nut 13, a hinge joint 14 and a fixed bracket 15. The connection base 11 is detachably connected to the machine body 200. One end of the connecting rod 12 is movably connected to the connection base 11 through a spherical plain bearing. The other end of the connecting rod 12 is connected to the connection nut 13. Both ends of the hinge joint 14 are movably connected to the fixed bracket 15 and the connection nut 13 respectively. Specifically, the bottom of the connection base 11 is detachably connected to the machine body 200 by bolts, and the top of the connection base 11 is movably connected to the connecting rod 12 through a spherical plain bearing, so that the connecting rod 12 can rotate around the connection point with the connection base 11. The other end of the connecting rod 12 is connected to the connection nut 13 to achieve quick disassembly and connection. The presence of the hinge joint 14 enables the traction device 100 to push or pull the track inspection instrument, realizing normal detection in both the forward and backward directions. At the same time, it can effectively overcome the vibrations generated in both the horizontal and vertical directions of the track during the rapid movement process.

[0026] As Figure 5 shown, it further includes a measuring wheel guiding component 5. The measuring wheel guiding component 5 includes a guiding bracket 51, a guiding shaft 52 and a deep groove ball bearing 53. The guiding bracket 51 is connected to the machine body 200. The guiding shafts 52 are arranged at both ends of the guiding bracket 51, and the deep groove ball bearings 53 are sleeved on the guiding shafts 52. Specifically, in this embodiment, two deep groove ball bearings 53 are mounted on both sides of the measuring wheel 4 through the guiding bracket 51 to achieve two-way guiding in both the forward and backward directions.

[0027] As Figure 6 shown, it further includes a measuring wheel retracting component 6. The measuring wheel retracting component 6 includes an electric push rod 61, a pulling rope 62, a slide rail 63 and a tension spring 64. The measuring wheel 4 is movably connected to the slide rail 63. The tension spring 64 is installed below the slide rail 63, and its movable end is connected to the measuring wheel 4. The electric push rod 61 is connected to the measuring wheel 4 through the pulling rope 62. Specifically, when the track inspection instrument passes through the turnout of the track 300, in order to prevent the measuring wheel 4 from getting stuck in the obturation space and prevent the measuring wheel 4 from colliding with the inner side of the turnout, it is necessary to retract the measuring wheel 4 in advance. At this time, the electric push rod 61 drives the measuring wheel 4 to displace away from the track 300 through the pulling rope 62. At this time, the tension spring 64 is compressed. The measuring wheel 4 is movably connected to the slide rail 63, so that the measuring wheel 4 has a linear displacement during the displacement process and will not deviate, which is convenient for resetting. After passing through the turnout, the electric push rod 61 is powered off. At this time, the tension spring 64 returns to its original state under its own spring force, driving the measuring wheel 4 to approach the track 300 and making it abut against the side wall of the track 300 again. The measuring wheel retracting component 6 can ensure that the track inspection instrument passes through the turnout smoothly without manual lifting, reducing the labor intensity of the inspection personnel.

[0028] As Figure 7As shown in the figure, it further includes a running wheel guiding assembly 7. The running wheel guiding assembly 7 includes a running guiding bracket 71, a running guiding wheel 72 and a running guiding bearing 73. The running guiding bracket 71 is connected to the machine body 200 and is respectively arranged at the front and rear ends of the running wheel 3. The running guiding wheel 72 is installed on the running guiding bracket 71 through the running guiding bearing 73. Specifically, in this embodiment, the running wheel guiding assembly 7 is used to guide the running wheel 3 to avoid the running wheel 3 running onto the wrong track when passing through a turnout.

[0029] The above embodiments only represent several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
