Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of light rail maintenance tools, specifically relating to a multi-purpose measuring ruler for two wheelsets. Background Technology
[0002] As a medium-capacity urban rail transit system, light rail trains typically run on two steel rails. This rail system allows light rail trains to operate at higher speeds and frequencies to meet the medium-capacity passenger transport needs of cities. The wheels of light rail trains are made of steel wheels, which are matched with the steel rails they run on, ensuring the stability and safety of train operation.
[0003] In routine maintenance, it is usually necessary to maintain the wheelsets of the light rail. When maintaining the two wheelsets, corresponding measuring tools are often used to measure parameters such as the distance between the two wheels, the diameter of the wheel body, and the thickness of the wheel body. However, many existing measuring tools have relatively single functions and cannot achieve the purpose of multi-purpose use. As a result, different measuring tools need to be changed during the measurement process, which is quite cumbersome. Utility Model Content
[0004] Based on the problems mentioned in the background technology above, this utility model provides a two-wheel multi-purpose measuring ruler to solve the problem that many existing measuring tools have relatively single functions and cannot achieve the purpose of multiple uses, which leads to the need to change different measuring tools during the entire measurement process, which is quite cumbersome.
[0005] The technical solution adopted in this utility model is as follows:
[0006] A multi-purpose measuring ruler for wheelsets includes:
[0007] The ruler rod has a contact head at both ends, one of which is fixed and the other can move along the axial direction of the rod.
[0008] The markings are set on the outer peripheral wall of the ruler rod along the axial direction;
[0009] Two contact heads are provided, and both are movably disposed on the outer peripheral wall of the ruler body in the axial direction.
[0010] Based on the above technical solution, the present invention has made the following improvements:
[0011] Furthermore, the ruler body includes a main ruler, an arc-shaped sleeve, and a secondary ruler. There are two main rulers, and the opposite ends of the two main rulers are connected by the arc-shaped sleeve. The secondary ruler is movably disposed inside the other end of one of the main rulers.
[0012] Furthermore, the contact head includes a measuring head, one of which is located at the end of one main ruler rod away from the arc-shaped sleeve, and the other measuring head is located at the end of the secondary ruler rod away from the arc-shaped sleeve; the measuring head is L-shaped, and a magnetic block is provided on the vertical part of the measuring head.
[0013] Furthermore, the markings include main markings and secondary markings. The main markings are axially arranged on the main ruler rod and on the bottom side wall of one of the measuring heads, and the secondary markings are axially arranged on the secondary ruler rod and on the bottom side wall of the other measuring head.
[0014] Furthermore, the second contact head includes a retaining plate, which is movably mounted on the outer peripheral wall of the corresponding main ruler rod along the axial direction via a sliding groove.
[0015] Furthermore, a magnetic plate is provided on the arc-shaped sleeve.
[0016] The beneficial effects of this utility model are:
[0017] 1. By combining the ruler body, two contact heads, and marking lines, the ruler body can be placed between the two wheels of the wheelset, and the two contact heads can be placed against the opposing walls of the two wheels of the wheelset. The distance between the two wheels is the sum of the values of the positions of the two contact heads on the marking lines.
[0018] 2. By combining the ruler body, marking line, and two contact heads, the ruler body is placed along the radial direction of the wheels of the two wheelset when in use, so that the two contact heads face each other against the outer circumferential wall of the wheel body. The sum of the position values of the two contact heads on the marking line is the diameter of the wheel body. Attached Figure Description

[0027] like Figures 1-5 As shown, a multi-purpose measuring ruler for two wheelsets includes:
[0028] The ruler body includes a main ruler 101, an arc-shaped sleeve 102, and a secondary ruler 103. There are two main rulers 101, and their opposite ends are connected by the arc-shaped sleeve 102. A magnetic plate 4 is provided on the arc-shaped sleeve 102. The secondary ruler 103 is movably disposed inside the other end of one of the main rulers 101. The secondary ruler 103 and the main ruler 101 together form a telescopic rod structure, which allows the length of the entire ruler body to be adjusted by extension or retraction.
[0029] Both ends of the ruler rod are provided with a contact head, one of which is fixed and the other is movable along the axial direction of the rod. The contact head includes a measuring head 201. One measuring head 201 is located at the end of one of the main ruler rods 101 away from the arc sleeve 102, and the other measuring head 201 is located at the end of the auxiliary ruler rod 103 away from the arc sleeve 102. The measuring head 201 is L-shaped, and a magnetic block 202 is provided on the vertical part of the measuring head 201.
[0030] See Figure 2 and Figure 4 By setting the measuring head 201 in an L-shape, when measuring the distance between the two wheels of a wheelset, the measuring rod can be placed between the two wheels of the wheelset, and then the auxiliary measuring rod 103 is pulled out from the end of the corresponding main measuring rod 101, so that the horizontal part of the two measuring heads 201 rests against the outer peripheral wall of the two wheels, and the vertical part rests against the opposing wall of the two wheels of the wheelset, so that the magnetic block 202 in the vertical part of the measuring head 201 is magnetized on the side wall of the wheel, thereby stably placing the measuring rod between the two wheels.
[0031] The markings are set on the outer peripheral wall of the ruler rod along the axial direction. The markings include a main marking 104 and a secondary marking 105. The main marking 104 is axially set on the main ruler rod 101 and on the bottom side wall of one of the measuring heads 201. The secondary marking 105 is axially set on the secondary ruler rod 103 and on the bottom side wall of the other measuring head 201. The zero point reference of the main marking 104 is located at the center of the arc sleeve 102, so that the main marking 104 on one of the main ruler rods 101 and the bottom side wall of one of the measuring heads 201 is symmetrically set with the main marking 104 on the other main ruler rod 101. The zero point reference of the secondary marking 105 is located on the side wall of the measuring head 201 at the end of the secondary ruler rod 103 away from the arc sleeve 102.
[0032] After the measuring rod is stably placed between the two wheels, the distance between the two wheels is obtained by observing the position of the two measuring heads 201 on the marking line and adding the full length values of the main marking line 104 on one measuring head 201, the full length values of the main marking line 104 on the other main measuring rod 101, and the extended value of the end of the secondary marking line 105 extending from the secondary measuring rod 103.
[0033] See Figure 1 , Figure 3 and Figure 5 Two contact heads are provided, each movably mounted on the outer peripheral wall of the ruler rod along the axial direction. Each contact head includes a locking plate 302, which is movably mounted on the outer peripheral wall of the corresponding main ruler rod 101 via a sliding groove 301. By placing the ruler rod along the radial direction of the wheels of the two wheels of the wheel pair, the arc-shaped sleeve 102 is locked onto the wheel axle, so that the magnetic plate 4 is magnetically engaged on the wheel axle, thereby stabilizing the ruler rod. At this time, the two locking plates 302 are moved to move and abut against the outer peripheral wall of the wheel. The sum of the position values of the two locking plates 302 on the main mark line 104 is equal to the diameter of the wheel. Thus, the ruler can be used for multiple purposes without having to change different measuring tools during the measurement process.
[0034] The present invention has been described in detail above. The specific embodiments are provided only to help understand the method and core idea of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
