Description

Technical Field

[0001] The utility model relates to a mounting frame, in particular to a magnetic steel mounting frame, and belongs to the technical field of magnetic steel mounting. Background Art

[0002] In order to ensure the stable operation of railway freight cars, passenger cars, high-speed trains and EMUs, a railway vehicle axle temperature detection system (THDS for short) is installed on the track. The THDS system uses trackside probes to detect the bearing temperature of the running vehicle in real time. It can detect the hot axle of the vehicle in time and is an important driving equipment to ensure the safety of railway transportation. It can realize early fault alarm and move the prevention threshold of accidents forward.

[0003] In the above system, multiple wheel sensors (such as magnets) need to be installed on the trackside to collect wheel signals to complete detection and diagnosis. However, there are more and more large-scale vehicles and vehicles with special wheel sizes on the railway lines. When they pass through the THDS system, maintenance personnel need to go to the equipment installation point to remove the magnets during the construction window period, and then install the magnets on the trackside after they pass through to avoid their wheels crushing the magnets. This operation not only consumes a lot of manpower and material resources, but also requires more construction windows to be reserved, which leads to low vehicle transportation efficiency.

[0004] In summary, how to propose a magnetic steel mounting frame to address the above technical issues has become an urgent problem to be solved by technicians in this field. Utility Model Content

[0005] The utility model aims at solving the above-mentioned deficiencies of the prior art and provides a magnetic steel mounting frame.

[0006] The technical solution of the utility model is: a magnetic steel mounting frame, comprising a first rail clamping block, a second rail clamping block, a fixing seat, a second bolt and a rectangular floating plate.

[0007] The first rail clamp and the second rail clamp are respectively clamped on both sides of the lower flange of the rail, the fixing seat is arranged on one side of the second rail clamp, and the first rail clamp, the second rail clamp and the fixing seat are connected by a first bolt.

[0008] The screw rod of the second bolt passes through the fixing seat and is connected to the rectangular floating plate. A spring is sleeved on the second bolt, and two ends of the spring are respectively against the fixing seat and the rectangular floating plate. The magnetic steel is installed on the upper surface of the rectangular floating plate.

[0009] Compared with the prior art, the utility model has the following effects:

[0010] 1. The utility model is based on application requirements. The fixed seat 130 and the rectangular floating plate 140 are supported by the spring 132. After the spring 132 is compressed, the rectangular floating plate 140 drops. After the spring 132 returns to its initial length, the rectangular floating plate 140 is restored to a normal height by the spring force. It is easy to install and use on site, so that vehicles with large machine operations or special wheel sizes do not need to disassemble and reinstall magnetic steel when passing through the THDS system, which reduces the work intensity of maintenance personnel and the time of skylight construction, providing a strong guarantee for improving railway transportation efficiency and driving safety; at the same time, it meets the needs of different vehicles passing through, and ensures the stable and accurate collection of wheel information.

[0016] In order to make the purpose, features and advantages of the invention of the utility model more obvious and easy to understand, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings of the utility model.

[0017] Specific implementation method 1: Combination Figures 1 to 4 To describe this embodiment, a magnetic steel mounting frame of this embodiment includes a first rail block 110 , a second rail block 120 , a fixing seat 130 , a second bolt 131 and a rectangular floating plate 140 .

[0018] The first rail block 110 and the second rail block 120 are both provided with grooves matching the lower flange of the rail. The first rail block 110 and the second rail block 120 are respectively clamped on both sides of the lower flange of the rail. The fixing seat 130 is arranged on one side of the second rail block 120. The first rail block 110, the second rail block 120 and the fixing seat 130 are connected by a first bolt 100.

[0019] The screw rod of the second bolt 131 passes through the fixing seat 130 and is connected to the rectangular floating plate 140. A spring 132 is sleeved on the second bolt 131. The two ends of the spring 132 are respectively against the fixing seat 130 and the rectangular floating plate 140. The magnet 141 is installed on the upper surface of the rectangular floating plate 140.

[0020] Specific implementation method 2: Combination Figures 1 to 4 To illustrate this embodiment, a stepped through hole is opened on the fixed seat 130 in this embodiment, and a second sleeve 143 is fixedly connected to the lower surface of the rectangular floating plate 140. The outer circumferential surface of the second sleeve 143 is slidably matched with the stepped through hole, and the screw portion of the second bolt 131 coaxially passes through the stepped through hole and is connected to the rectangular floating plate 140.

[0025] How it works

[0026] Combination Figures 1 to 4 Explain the working principle of the utility model:

[0027] The first rail block 110 and the second rail block 120 are respectively clamped on both sides of the lower flange of the rail, the fixing seat 130 is arranged on one side of the second rail block 120, and the first rail block 110, the second rail block 120 and the fixing seat 130 are connected by a first bolt 100.

[0028] The screw rod of the second bolt 131 passes through the fixing seat 130 and is connected to the rectangular floating plate 140. A spring 132 is sleeved on the second bolt 131. The two ends of the spring 132 are respectively against the fixing seat 130 and the rectangular floating plate 140. The magnet 141 is installed on the upper surface of the rectangular floating plate 140.

[0029] When large-scale vehicles and vehicles with special wheel sizes pass by the magnet, their wheels are first pressed against the magnet protective cover 142. As the wheels continue to roll forward, the spring 132 is compressed and the rectangular floating plate 140 drops, ensuring that the magnet 141 collects wheel information while also ensuring that the magnet will not be damaged. After large-scale vehicles and vehicles with special wheel sizes pass by, the rectangular floating plate 140 returns to its normal height under the action of the spring force, satisfying the information collection of the wheels of conventional vehicles (railway freight cars, passenger cars, high-speed trains and EMUs).

[0030] The present invention has been disclosed as above in the form of a preferred embodiment, but it is not intended to limit the present invention. Any simple modification, equivalent changes and modifications made to the above implementation cases by any professional and technical personnel who do not deviate from the content of the technical solution of the present invention and based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
