Description

Technical Field

[0001] The utility model relates to the technical field of parts of a track inspection instrument, in particular to an electric wheel retracting mechanism. Background Art

[0002] A track inspection instrument is a detection instrument dedicated to measuring and analyzing the internal geometric parameters of railway tracks, which can accurately detect parameters such as gauge, superelevation, level, alignment, vertical profile, chord, twist (triangle depression), and gauge change rate. The use of an integral frame design, high-precision imported sensors, and a perfect analysis model ensures the accuracy of the measurement data. When in use, the track inspection instrument is placed on the track and manually pushed to travel on the track at a speed of about 5 km / h to complete the measurement of the track geometric parameters. However, when the current track inspection instrument passes through the turnout of the track, since the measuring wheel runs closely against the side of the rail under the action of the spring force, it will get stuck in the harmful space of the turnout when passing through the turnout, causing damage to the parts. Therefore, it is necessary for the inspection personnel to manually lift the track inspection instrument over the turnout, which increases the work intensity of the inspection personnel. Therefore, improvement is needed. Content of the Utility Model

[0003] Based on this, in view of the above problems, it is necessary to provide an electric wheel retracting mechanism.

[0004] An electric wheel retracting mechanism includes a driving member, a pulling rope, a measuring wheel, a running wheel, a bracket, a slide rail, and a tension spring. The running wheel and the measuring wheel are both movably installed on the bracket. The running wheel contacts the rail surface of the track, and the measuring wheel is movably abutted against the side wall of the track. The bracket is movably connected to the cross beam of the track inspection instrument through the slide rail. The tension spring is arranged below the slide rail, and the movable end of the tension spring is connected to the bracket. The output end of the driving member is connected to the bracket through the pulling rope.

[0005] Preferably, the pulling rope is made of steel wire rope.

[0006] Preferably, the driving member is an electric push rod.

[0007] The beneficial effect of the utility model is that the driving member drives the measuring wheel to move through the pulling rope, keeping a certain distance from the side wall of the track, so that when the track inspection instrument passes through the turnout, it will not be blocked by the measuring wheel, enabling the track inspection instrument to pass through the turnout smoothly without manual handling, reducing the labor intensity of the inspection personnel.

[0010] To make the above objects, features, and advantages of the present utility model more apparent and understandable, the following detailed description of the specific embodiments of the present utility model will be given in conjunction with the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0011] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation.

[0012] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used in the description of the present utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0013] Such as Figures 1 - 2As shown in the figure, an electric wheel retracting mechanism includes a driving member 1, a pulling rope 2, a measuring wheel 3, a traveling wheel 4, a bracket 5, a slide rail 6 and a tension spring 7. The traveling wheel 4 and the measuring wheel 3 are both movably installed on the bracket 5. The traveling wheel 4 is in contact with the rail surface of the track 100, and the measuring wheel 3 is movably abutted against the side wall of the track 100. The bracket 5 is movably connected to the cross beam of the track inspection instrument (not shown in the figure) through the slide rail 6. The tension spring 7 is arranged below the slide rail 6, and the movable end of the tension spring 7 is connected to the bracket 5. The output end of the driving member 1 is connected to the bracket 5 through the pulling rope 2. Specifically, during normal use, the track inspection instrument travels on the track 100 by itself. The traveling wheel 4 is held by the bracket 5 and is in contact with the rail surface of the track 100, with rolling friction to reduce the walking friction resistance. Before passing through the turnout, the operator controls the driving member 1 to start, pulls the bracket 5 through the pulling rope 2, drives the traveling wheel 4 and the measuring wheel 3 to displace synchronously. At this time, the measuring wheel 3 displaces to the side away from the track 100, and the bracket 4 displaces along the slide rail 6, so that the measuring wheel 3 maintains a linear displacement. The driving member 1 drives the measuring wheel 3 away from the track 100 through the pulling rope 2 and keeps the distance from the track 100 at 1435 mm, that is, the measuring wheel 3 does not contact the inner edge of the track 100 (but the distance cannot be too large either, as it cannot pass through the turnout if it is too large, so it is at the position of the 1435 mm standard gauge). In this way, the track inspection instrument can pass through the turnout smoothly. It can be known that during the displacement of the bracket 4, the traveling wheel 4 displaces synchronously. Because the width of the traveling wheel 4 is relatively wide, when the measuring wheel 3 displaces to the farthest point away from the track 100, the traveling wheel 4 will not separate from the rail surface of the track 100, thus preventing the track inspection instrument from falling off the track 100. After passing through the turnout, the driving member 1 is powered off. Under the action of the spring force of the tension spring 7, the bracket 5 resets, drives the measuring wheel 3 to displace towards the side close to the track 100, and the measuring wheel 3 can re-abut against the side wall of the track 100, and then the next stage of track inspection can start.

[0014] Specifically, in this embodiment, the pulling rope 2 is made of steel wire rope, which has high structural strength and long service life.

[0015] Specifically, in this embodiment, the driving member 1 is an electric push rod. The electric push rod is convenient to be directly connected to the pulling rope 2, and has a fast response speed and high precision control.

[0016] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on 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.
