Abstract
Description
Technical Field
[0001] This utility model relates to the field of railway construction technology, specifically to an adjustable offset detector for a D-shaped beam. Background Technology
[0002] D-beams are temporary track reinforcement devices used in railway construction. Their core function is to ensure safe construction by bridging existing tracks. During railway operation, D-beams may shift due to vibration, changes in geological conditions, ambient temperature variations, or material aging. When the shift exceeds a reasonable range, it can exacerbate train vibrations or even lead to derailment, thus affecting train operation safety. Therefore, railway maintenance personnel need to regularly detect and maintain the D-beams to ensure a reasonable shift range.
[0003] Traditional D-beam offset detection requires point-to-point measurement using equipment such as levels, plumb bobs, and total stations. This process necessitates operators selecting suitable measurement locations based on the site conditions, setting up and adjusting the equipment, and recording data. Repeated measurements are often necessary to ensure accuracy, resulting in a lengthy and inefficient process. Furthermore, weather conditions at the construction site and the operator's skill level can affect the accuracy of the offset data, thus impacting construction safety. Additionally, carrying the instruments increases the workload for the operators.
[0004] Therefore, there is a need for a D-beam offset detection device that can both improve the offset detection efficiency of D-beams and ensure the offset detection accuracy of D-beams. Utility Model Content
[0005] This invention provides an adjustable offset detector for D-shaped beams, which improves the offset detection efficiency of D-shaped beams while ensuring the offset detection accuracy.
[0006] To solve the above problems, the present invention provides an adjustable offset detector for a D-shaped beam, which adopts the following technical solution:
[0007] A D-shaped beam adjustable offset detector includes a support frame and multiple detection rods. The support frame supports the detection rods, and each detection rod includes an inner top rod, an outer outer rod, and an elastic element. The outer outer rod is a hollow columnar structure with one end sealed and is fixedly installed on the support frame. The elastic element is installed inside the outer outer rod. One end of the inner top rod passes through the outer outer rod, and the other end of the inner top rod is used to abut against the test surface under the action of the elastic element. The inner top rod has a scale.
[0008] This utility model discloses an adjustable offset detector for a D-shaped beam. Multiple detection rods, perpendicular to the surface to be measured on one side of the D-shaped beam, are fixedly installed. This allows the vertical or horizontal offset of the D-shaped beam to be directly displayed via offset scales on the detection rods. Compared to traditional detection equipment, this detector eliminates the need for manual installation and debugging, improving detection efficiency while reducing the workload of operators. It also avoids detection errors caused by weather conditions and varying operator skill levels, ensuring accurate offset detection. Furthermore, the purely mechanical design guarantees the detector's reliability and operational stability.
[0009] Furthermore, the elastic element is a spring.
[0010] Furthermore, the support frame includes a fixed plate and a support column vertically mounted on the fixed plate. One end of the support column is fixed at the center of the fixed plate, and each outer sleeve rod is arranged along the axial direction of the support column and vertically fixed on the support column.
[0011] Furthermore, the outer sleeve is fixed to the support column by welding or fastening.
[0012] Furthermore, a lubricant is provided between the outer rod and the inner push rod to reduce the sliding friction between them.
[0013] Its beneficial effects are as follows: by adding lubricant between the inner push rod and the outer push rod, the sliding friction between the inner push rod and the outer push rod is reduced. At the same time, the lubricant can enhance the corrosion resistance of the inner push rod surface and the inner wall of the outer push rod, avoid rusting at the contact surface of the inner push rod and the outer push rod, and thus avoid jamming between the inner push rod and the outer push rod, thereby improving the stability of the detection rod in use.
[0014] Furthermore, the end of the inner push rod that abuts against the surface to be measured has a tapered structure to improve the accuracy of the deviation detection.
[0015] Its beneficial effect is that by setting the end of the inner push rod that abuts against the surface to be measured as a conical structure, the inner push rod always maintains point contact with the surface to be measured, thereby improving the offset detection accuracy of the detector.
[0016] Furthermore, the cross-sections of the inner top rod and the outer top rod are circular, rectangular, or polygonal.
[0017] Furthermore, each of the detection rods is arranged horizontally / vertically opposite the test surface to detect the deviation of the test surface in the horizontal / vertical direction, and the fixing plate is fixedly installed on the ground or base structure by bolts.
[0018] The beneficial effects of the D-beam adjustable offset detector provided by this utility model are:
[0019] 1. This utility model discloses an adjustable offset detector for a D-shaped beam. By fixing multiple detection rods perpendicular to the surface to be measured on one side of the D-shaped beam, the vertical or horizontal offset of the D-shaped beam can be directly displayed through the offset scale on the detection rods. Compared with traditional detection equipment, this detector saves the manual installation and debugging process, improves detection efficiency, reduces the labor intensity of operators, avoids detection errors caused by weather and different operator skill levels, and ensures the accuracy of offset detection. In addition, the purely mechanical structure design also ensures the reliability and stability of the detector.
[0020] 2. By adding lubricant between the inner push rod and the outer push rod, the sliding friction between them is reduced. At the same time, the lubricant can enhance the corrosion resistance of the inner push rod surface and the inner wall of the outer push rod, preventing rust from forming on the contact surface between the inner push rod and the outer push rod, thereby preventing jamming between the inner push rod and the outer push rod and improving the stability of the detection rod in use.
[0021] 3. By setting the end of the inner push rod that abuts against the surface to be measured as a conical structure, the inner push rod always maintains point contact with the surface to be measured, thus improving the offset detection accuracy of the detector. Attached Figure Description

[0027] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.
[0028] Embodiment 1 of the adjustable offset detector for a D-beam provided by this utility model:
[0029] like Figures 1 to 2 As shown, the adjustable offset detector for the D-shaped beam 3 includes a support frame 1 and detection rods 2. The support frame 1 is defined as being located on the right side of the D-shaped beam 3. The detection rods 2 are fixedly installed on the support frame 1, with 2-4 detection rods 2 on each support frame 1. The support frame 1 is fixedly installed on the ground or on a base structure such as a concrete seat according to the detection requirements, so that each detection rod 2 is vertically contacting the surface to be measured of the D-shaped beam 3 while being arranged horizontally or vertically on the support frame 1.
[0030] The support frame 1 is described below. It includes a fixed plate 11 and a support column 12. The fixed plate 11 is a square Q345 steel plate with dimensions of 150mm × 150mm × 10mm. Four mounting holes for bolts are evenly distributed around the center of the fixed plate 11. The support column 12 is a cylindrical steel pipe structure with an outer diameter of 50mm and a wall thickness of 2mm. The support column 12 is vertically fixed to the center of the fixed plate 11 by welding and is used to fix and install the detection rod 2.
[0031] The detection rod 2 is described below. The detection rod 2 includes an inner top rod 22, an outer outer rod 21, and an elastic element 23. The outer outer rod 21 is a cylindrical, hollow rod closed at the right end. The outer outer rod 21 is made of Q345 steel, with an outer diameter of 15mm, a wall thickness of 1.5mm, and a length of 200mm. The outer outer rod 21 is welded horizontally to the outer wall of the support column 12. The elastic element 23 is a spring, which passes through the interior of the outer outer rod 21, with its right end abutting against the inner wall of the right end of the outer outer rod 21.
[0032] The inner push rod 22 is a cylindrical hollow rod structure made of Q345 steel. It has an outer diameter of 10mm, a wall thickness of 1.5mm, and a length of 180mm. The right end of the inner push rod 22 is closed, while its left end is a tapered structure with its tip pointing left, used to contact the surface to be measured. The outer wall of the inner push rod 22 is engraved with increments of 24 from left to right, each 150mm long, to indicate the offset distance of the surface to be measured. The right end of the inner push rod 22 is inserted into the outer sleeve rod 21 and, under the pushing action of the spring, contacts the surface to be measured to the left. The inner wall of the outer sleeve rod 21 is coated with lubricating oil to reduce the sliding friction between the inner push rod 22 and the outer sleeve rod 21, thereby increasing the sensitivity of the detector. At the same time, the lubricating oil can enhance the corrosion resistance of the contact surface between the inner push rod 22 and the outer sleeve rod 21, preventing the inner push rod 22 from rusting and causing it to jam and fail, thus ensuring the stability of the detector in use.
[0033] The working principle of a D-type beam 3 adjustable offset detector is summarized as follows:
[0034] According to the testing requirements, when it is necessary to test the horizontal offset, the mounting plate is fixed to the concrete base with bolts on the side of the D-shaped beam 3. At this time, the support column 12 is in a horizontal position, and each testing rod 2 is perpendicularly contacted with the surface to be tested of the D-shaped beam 3 along the extension direction of the support column 12. When it is necessary to test the vertical offset, the support frame 1 is vertically fixed to the ground, and each testing plate is perpendicularly contacted with the surface to be tested of the D-shaped beam 3 along the vertical direction.
[0035] When the D-beam 3 shifts laterally or vertically, the corresponding shift data will be directly displayed on the scale 24 of the inner top rod 22. At this time, the operator can determine the shift of the D-beam 3 by comparing it with the initially recorded scale value, without having to carry detection equipment. This saves on operation and debugging steps and greatly improves detection efficiency and accuracy.
[0036] Embodiment 2 of the adjustable offset detector for a D-beam provided by this utility model:
[0037] Its main difference from Example 1 is:
[0038] In Example 1, the outer sleeve rod and the support column are fixedly connected by welding.
[0039] In this embodiment, the outer rod is fixedly installed on the support column by a cross-shaped fastener.
[0040] Embodiment 3 of the adjustable offset detector for a D-beam provided by this utility model:
[0041] Its main difference from Example 1 is:
[0042] In Example 1, the elastic element is a spring.
[0043] In this embodiment, the elastic element is elastic rubber.
