Description

Technical Field

[0001] The utility model relates to the field of track scale auxiliary equipment in the metallurgical industry, and in particular to a fixing device for a track scale axle sensor. Background Art

[0002] Track scales are responsible for measuring the materials transported in and out of factories by rail. Vehicle on-scale detection is an important part of the unmanned weighing system of track scales. Currently, track scales install axle counting sensors on the steel rails on the weighing table, and cooperate with software to achieve effective vehicle identification.

[0003] The axle counting sensor is a capacitive sensor type. The induction head is a square flat electrode, which forms a distributed capacitance with the ground wire of the oscillation circuit. When a conductor or other medium approaches the induction head, the capacitance increases and the oscillator stops oscillating. The electrical signal is output through the shaping amplifier. Every time an axis passes through, a signal is sent out, and the effective weighing section is determined by calculating the number of axes.

[0004] There are two main ways to fix axle counter sensors on the market. One is to use electric welding to weld them directly to the rails. Since the welding surface is small and no protective measures are taken for the equipment, the train vibrates back and forth with a large amplitude when passing through the track scale, which can easily cause the sensor to fall off and lead to leakage. The other is to directly groove and drill holes in the weighing rails and lock the axle counter sensors to the rails with bolts. Grooving and drilling holes in the rails can easily cause insufficient strength of the rails at this point. Over time, cracks can easily appear at this point, posing a major safety hazard. Utility Model Content

[0005] The purpose of the utility model is to provide a fixing device for a track scale axle sensor in view of the shortcomings and defects in the prior art. The fixing device fixes the axle sensor to a fixing plate and fixes the fixing device to the track by a butterfly spring bar pressure plate. This can effectively solve the safety hazard caused by the sensor falling off and causing leakage or rail cracking during the weighing process of the track scale due to the large back and forth vibration of the train.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a fixing device for a track scale axle sensor, which includes a first side baffle 1, a fixed plate 2, a second side baffle 3, and a connecting bottom plate 5, the first side baffle 1 is welded to one side of the fixed plate 2, the second side baffle 3 is welded to the other side of the fixed plate 2, and the outer end of the second side baffle 3 is welded to the connecting bottom plate 5, and a reinforcing rib plate 4 is welded between the second side baffle 3 and the connecting bottom plate 5.

[0007] Furthermore, the fixing plate 2 is provided with two fixing through holes 101 for fixing the track scale axle sensor.

[0008] Furthermore, a long slot hole 501 is formed on the connecting bottom plate 5 .

[0009] Furthermore, the fixing plate 2 is disposed between the first side baffle 1 and the second side baffle 3 , and two sides of the fixing plate 2 are respectively perpendicular to the first side baffle 1 and the second side baffle 3 .

[0010] Furthermore, the distance between the bottom edge of the fixed plate 2 and the bottom edges of the first side baffle 1 and the second side baffle 3 is A, the length of A is 7 mm, and the distance between the bottom edge of the connecting bottom plate 5 and the bottom edge of the second side baffle 3 is B, the length of B is 5 mm.

[0011] After adopting the above technical scheme, the beneficial effect of the utility model is as follows: the fixing device fixes the axle counter sensor on the fixing plate and fixes the fixing device on the track through the butterfly spring bar pressure plate, which can effectively solve the safety hazard caused by the sensor falling off and causing leakage or rail cracking during the weighing process of the track scale due to the large amplitude of the train's back and forth vibration.

[0017] See also Figure 1-Figure 3 As shown, the technical solution adopted in this specific embodiment is: it includes a first side baffle 1, a fixed plate 2, a second side baffle 3, and a connecting bottom plate 5, the first side baffle 1 is welded to one side of the fixed plate 2, the second side baffle 3 is welded to the other side of the fixed plate 2, and the outer end of the second side baffle 3 is welded to the connecting bottom plate 5, and a reinforcing rib plate 4 is welded between the second side baffle 3 and the connecting bottom plate 5.

[0018] To be more specific, the fixing plate 2 is provided with two fixing through holes 101 for fixing the track scale axle sensor.

[0019] More specifically, a long slot hole 501 is provided on the connecting bottom plate 5. The long slot hole 501 is used to cooperate with the butterfly spring bar pressure plate to fix the connecting bottom plate 5 on the track.

[0020] More specifically, the fixing plate 2 is disposed between the first side baffle 1 and the second side baffle 3, and the two sides of the fixing plate 2 are respectively perpendicular to the first side baffle 1 and the second side baffle 3. The first side baffle 1, the fixing plate 2 and the second side baffle 3 cooperate with each other to form a groove pattern, thereby better protecting the axle counter sensor.

[0021] More specifically, the distance between the bottom edge of the fixed plate 2 and the bottom edges of the first side baffle 1 and the second side baffle 3 is A, the length of A is 7 mm, and the distance between the bottom edge of the connecting bottom plate 5 and the bottom edge of the second side baffle 3 is B, the length of B is 5 mm.

At this time, the first side baffle 1 and the second side baffle 3 on both sides of the fixed plate 2 can form a groove pattern, which can better protect the track scale axle sensor. Then, the butterfly spring bar pressure plate is passed through the long slot hole 501 on the connecting bottom plate 5, and the butterfly spring bar pressure plate is used to fix the fixing device on the track, which effectively prevents the axle sensor from falling off due to the large amplitude of the train's back and forth vibration, resulting in leakage problems or rail cracks. Safety hazards caused by this.
