Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of track inspection instruments, in particular to an anti-tripping mechanism for track inspection instruments. Background Art
[0002] In recent years, my country's rail transit industry has developed rapidly. The government has increased investment in railway construction, with new lines entering operation annually. By the end of 2023, China's operating railway mileage will reach 159,000 kilometers, including 45,000 kilometers of high-speed rail. Local governments have also accelerated the construction of subways in central cities. A total of 55 cities across China now have subways, with a total operating mileage of 10,000 kilometers. Ensuring the safety of rail transportation is an eternal priority, requiring the use of advanced inspection tools to continuously inspect transportation equipment and promptly identify and address equipment defects. Track inspection instruments are currently the most widely used instrument for inspecting track geometry, in addition to large, specialized inspection vehicles, during new line acceptance inspections, overhauls, and routine maintenance. These instruments utilize fiber optic gyroscopes, inclinometers, linear displacement sensors, and rotary encoders to measure track geometry, including gauge, level, height, direction, and twist (triangular pits). The instrument is placed on the track and manually pushed at approximately 5 km / h to measure track geometry. To improve inspection efficiency, powered track inspection instruments have emerged, capable of operating at speeds of up to 12 km / h. Since the track inspection instrument has a light weight, it may jump off the track and go off the track when it moves quickly on the track. Therefore, measures must be taken to prevent the track inspection instrument from jumping off the track and derailing. Utility Model Content
[0003] Based on this, it is necessary to provide an anti-tripping mechanism for a track inspection instrument to address the above problems.
[0004] A track inspection instrument anti-tripping mechanism includes a locking clip, a plug and a pressure contact member, the pressure contact member includes a pressure rod, a mounting seat, a pressure spring sleeve, a pressure spring guide shaft, a pressure spring, a limit sleeve and a ball, one end of the pressure rod is detachably connected to the locking clip through a plug, and the other end of the pressure rod is connected to the mounting seat, the pressure spring sleeve is vertically arranged in the mounting seat, the pressure spring guide shaft passes through the pressure spring sleeve, the pressure spring is arranged in the pressure spring sleeve and sleeved on the pressure spring guide shaft, the two ends of the pressure spring are respectively abutted against the upper inner wall and the lower inner wall of the pressure spring sleeve, the limit sleeve is connected to the lower end of the pressure spring guide shaft, and the ball is movably clamped in the lower end of the limit sleeve.
[0005] Preferably, the plug includes a clamping seat and a plug body, the clamping seat is connected to the end of the pressure rod, one end of the plug body is detachably inserted into the clamping seat by a bolt, and the other end of the plug body is detachably inserted into the locking clamp.
[0006] Preferably, the locking clip comprises a hanging plate and a locking clip, the locking clip is movably mounted on both sides of the hanging plate, one end of the plug body is inserted into the hanging plate, and the locking clip is movably engaged with the plug body.
[0007] Preferably, the outer sides of the upper and lower ends of the compression spring sleeve are wrapped with rubber sleeves, and the rubber sleeves abut against the inner side of the mounting seat.
[0008] The benefits of this utility model lie in its use of a ball bearing that presses against the surface of the track detector, reducing wear on the contact areas of the track detector. Furthermore, a built-in compression spring imparts a degree of elasticity to the compression rod, also providing a shock-absorbing effect. This ensures a certain level of pressure, preventing the track detector from jumping off the track during travel, and also preventing excessive pressure from increasing resistance on the track detector's running wheels.

[0012] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0013] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.
[0014] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0015] like Figures 1 to 3 As shown, an anti-tripping mechanism for a track inspection instrument includes a locking clip 1, a plug 2 and a pressure contact member 3, the pressure contact member 3 includes a pressure rod 31, a mounting seat 32, a compression spring sleeve 33, a compression spring guide shaft 34, a compression spring 35, a limiting sleeve 36 and a ball 37. One end of the pressure rod 31 is detachably connected to the locking clip 1 through the plug 2, and the other end of the pressure rod 31 is connected to the mounting seat 32. The compression spring sleeve 33 is vertically arranged in the mounting seat 32, and the compression spring guide shaft 34 passes through the compression spring sleeve 33. The compression spring 35 is arranged in the compression spring sleeve 33 and is sleeved on the compression spring guide shaft 34. The two ends of the compression spring 35 respectively abut against the upper inner wall and the lower inner wall of the compression spring sleeve 33, the limiting sleeve 36 is connected to the lower end of the compression spring guide shaft 34, and the ball 37 is movably engaged in the lower end of the limiting sleeve 36. Specifically, in this embodiment, when in use, the locking clip 1 is used to connect with the traction device 100, and the plug 2 serves as an intermediate structure for connecting the locking clip 1 and the pressure contact member 3, so that the pressure contact member 3 and the locking clip 1 are quickly connected. The pressure contact member 3 includes a pressure rod 31, a mounting seat 32, a pressure spring sleeve 33, a pressure spring guide shaft 34, a pressure spring 35, a limit sleeve 36 and a ball 37. In this embodiment, the pressure rod 31 is a double-rod design with higher structural strength and can be made of steel pipe welding with low cost. The front end of the pressure rod 31 is connected to the plug 2, and the rear end mounting seat 32 is welded. The cross section of the bracket 32 is U-shaped. A compression spring sleeve 33 is vertically installed in the mounting seat 32. A compression spring guide shaft 34 passes through the compression spring sleeve 33, and its lower end extends outside the compression spring sleeve 33 and is connected to a limit sleeve 36. A ball 37 is movably mounted on the lower end of the limit sleeve 36. When the track detector 200 is in use, it is pulled by the traction device 100 through another connecting rod and moves on the track. At this time, the pressure of the ball 37 acts on the end face of the track detector 200, and the rolling friction with the end face of the track detector 200 is low, which will not cause wear on the contact parts of the track detector. In addition, due to the presence of the compression spring 35, when the track detector 200 moves on the track and is subject to vibration and jump, the vibration is absorbed by the compression spring 35, which acts as a shock absorber and ensures a certain pressure to prevent the track detector from jumping off the track during travel, and will not increase the resistance of the track detector's running wheels due to excessive pressure.
[0016] like Figures 2-3As shown, the plug 2 includes a clamping base 21 and a plug body 22. The clamping base 21 is connected to the end of the pressure rod 31. One end of the plug body 22 is detachably inserted into the clamping base 21 via a bolt, and the other end of the plug body 22 is detachably inserted into the locking clamp 1. Specifically, the plug body 22 is cylindrical and is connected to the clamping base 21 via bolts. The other end of the plug body 22 is inserted into the locking clamp 1. The detachable connection enables quick disassembly and assembly.
[0017] like Figures 2-3 As shown, the locking clamp 1 includes a mounting plate 11 and a locking clamp 12. The locking clamp 12 is movably mounted on both sides of the mounting plate 11. One end of the plug body 22 is inserted into the mounting plate 11, and the locking clamp 12 is movably engaged with the plug body 11. Specifically, in this embodiment, the mounting plate 11 is L-shaped and detachably connected to the pulling device 100 via bolts. The locking clamp 12 has wrenches on both sides. The user tightens the wrenches to manually lock the inserted plug body 22, achieving a detachable connection.
[0018] like Figures 2-3 As shown, the upper and lower ends of the compression spring sleeve 33 are wrapped with rubber sleeves 331, and the rubber sleeves 331 abut against the inner side of the mounting seat 32. Specifically, the rubber sleeves 331 play a buffering role, preventing the two ends of the compression spring sleeve 33 from hard contact with the inner side of the mounting seat 32, and cooperating with the compression spring 35 to reduce shock.
[0019] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention.
