Description

TECHNICAL FIELD

[0001] The utility model relates to a turnout inspection ruler, concretely relates to an improved multifunctional turnout inspection ruler, and is mainly used for checking or detecting railway turnout and belongs to the technical field of railway track detection. BACKGROUND

[0002] Generally speaking, turnout inspection is an important operation project of the railway maintenance department, and mainly provides technical data and quality control basis for maintenance.

[0003] The purpose and role of turnout inspection in the railway mainly focus on ensuring the safety, stability and efficiency of railway transportation. As a crucial component of the railway network, turnout determines whether the train can smoothly switch lines. Specifically, the purpose and role of turnout inspection include the following aspects:

[0004] First, to prevent train derailment or accidents: the normal operation of turnout is directly related to the safety of train travel. By checking various components of turnout, such as track, switch, control device, etc., hidden dangers can be found in time to avoid train derailment, collision and other safety accidents caused by turnout failure;

[0005] Second, to ensure smooth switching: turnout needs to be checked regularly to ensure that its switching mechanism is flexible and smooth, especially to check whether the sliding parts, switches, turnout heart rails, etc. of turnout have problems such as wear, deformation, etc., to prevent turnout from being unable to accurately switch due to improper operation or equipment damage;

[0006] Third, to reduce wear and damage: during the long-term use of turnout, various components may wear, deform or loosen. By regular inspection and maintenance, these problems can be found in time for necessary repair or replacement to avoid further damage to the equipment and thus prolong the service life of the turnout;

[0007] Fourth, to reduce the stoppage or delay caused by failure: turnout failure not only brings safety hazards, but also may cause train stoppage or delay due to the inability to smoothly switch tracks. Regular inspection and maintenance of turnout equipment help to reduce the frequency of failure and improve the efficiency of railway transportation;

[0008] Railway workers use track gauge rulers and branch distance rulers for turnout inspection on a daily basis, and some turnout frame inspection rulers have appeared in recent years. However, they all have the problem of single function.

[0009] At present, the railway staff uses the railway offset ruler and turnout frame inspection ruler on site, which has single function, can only check the railway turnout offset or turnout frame, and even some railway staff still use steel tape and steel ruler when checking the size of turnout frame and guard rail interval, which has the safety hidden danger of easy to connect two steel rails to cause red light belt, and the accuracy of inspection is greatly affected by human factors, and the precision of inspection is very low.

[0010] At present, after searching, the Chinese utility model patent with patent publication number CN221593704U discloses a multifunctional railway turnout inspection ruler, which comprises: a reference end plate (1), two reference positioning cylinders (11) are vertically arranged at the bottom of the reference end plate (1), which are used for positioning the size reference of measurement, the vertical surface of the two quadrant points at the front end of the two reference positioning cylinders (11) is a first measurement reference surface (111), and the vertical surface of the two quadrant points at the rear end of the two reference positioning cylinders (11) is a second measurement reference surface (112); a ruler rod (2) is fixed at the front end of the reference end plate (1), and the ruler rod (2) is perpendicular to the first and second measurement reference surfaces (111, 112); a main ruler (3) is arranged on the top surface of the ruler rod (2); a sliding vernier assembly (4) is slidably arranged on the ruler rod (2), and a reading scale (431) is arranged at the position corresponding to the main ruler (3) at the top of the sliding vernier assembly (4); a vernier measurement block (42) is arranged on one side of the sliding vernier assembly (4), the vernier measurement block (42) extends below the bottom surface of the sliding vernier assembly (4), is used for closely positioning the turnout measurement surface, and simultaneously serves as a size reference for measurement of a vice ruler (5); and the vice ruler (5) is slidably arranged on one side of the sliding vernier assembly (4) and is used for measuring turnout size inspection with a size of not more than 200 mm. Although the above-mentioned design structure of the multifunctional railway turnout inspection ruler can complete the traditional turnout offset and turnout frame inspection, and can also complete the inspection of turnout guard rail interval, wing rail interval, point rail stroke, guard rail top width, center rail width, flange groove width, and inspection interval and back distance, the above-mentioned patent still has the following technical defects and deficiencies:

[0011] On the one hand, there are many measurement reference surfaces, and for each measurement, the corresponding readings of the two main rulers and one vice ruler need to be found according to the measurement reference surface, and the two reading scales on each reading ruler are close to each other, so that the operating personnel are easy to misread if they do not concentrate;

[0012] On the other hand, in order to make the two sides of the vice ruler reference block at the front end of the vice ruler serve as the measurement reference surface, the vice ruler reference block is designed as a transversely slidable structure, so that the measurement reference surfaces on the two sides of the vice ruler reference block can be aligned with the zero scale line of the vice ruler. In this way, the operating personnel need to slide the vice ruler reference block to the position to measure accurately, which is not convenient to operate, and the operating personnel can only observe whether the vice ruler reference block is slid to the position by naked eyes, which is easy to be affected by human factors, the measurement precision is low, and in general, it is very inconvenient.

[0013] Therefore, developing an improved multifunctional turnout inspection ruler with higher practicability and reliability is the key to solve the above technical problems. SUMMARY

[0014] In view of the defects and deficiencies in the prior art that the traditional railway worker uses a steel tape and a steel ruler to check the size of a turnout frame and the interval of guard rails, which has the safety hazard of easy jointing two rails to cause a red light belt, and the accuracy of the checked value is greatly affected by human factors and the checking precision is extremely low, the utility model discloses an improved and innovative structure, which aims at providing a simple structure, strong practicability, novel and reasonable design, improved checking accuracy, enhanced operation safety, and the ability to check the interval of a turnout, the distance between a guard rail and a back, the width of a rail groove of a wing rail, the minimum distance between a frame of a turnout and a basic rail, the rail support distance of each part of a turnout, the track gauge, and the wear of a guard rail, thereby improving the efficiency and accuracy of turnout checking operation, eliminating the unsafe factors of track circuit jointing in the operation process, and enhancing the operation safety.
