AI Technical Summary
When the existing weighing device is subjected to multiple weighings, the downward force is applied to the load sensor, causing the sensor to deform and the fixed connection to be relaxed, which leads to the track shift, posing a safety hazard.
The track is connected to the track and the base through fixed blocks, guide rods and springs, and shock absorbing to prevent the track from breaking away from the base. At the same time, the track A and track B are slidably connected through the slide rails and sliders to prevent the track from being offset.
The stable connection and shock absorption of the track are achieved, and the tracks are prevented from being offset and disengaged, which improves safety and reliability, and ensures the accuracy and reliability of the weighing process.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of weighing tracks, in particular to a weighing device for materials entering a wellhead. Background Art
[0002] During the coal mining process, in order to ensure safe transportation, the weight of the coal transported by the railcar each time cannot exceed a certain threshold, otherwise it will cause damage to the track, resulting in serious safety hazards. Workers cannot control the specific weight of the coal when pouring it into the railcar, so the coal transported by the railcar needs to be weighed.
[0003] Existing weighing devices usually have a weighing sensor under the track, and the track and the weighing sensor are fixedly connected by a locking piece, a locking plate and a fixed pressure plate; however, when weighing, the track applies a downward force to the weighing sensor, and the weighing sensor will deform, resulting in a gap between the locking piece, the locking plate, the fixed pressure plate and the track. Repeated weighing over a long period of time will cause the fixed pressure plate to loosen, making it impossible to fix the track and the weighing sensor, which will lead to track deviation and pose certain safety hazards.

[0006] As an optimization, both ends of track A are respectively connected to track B extending axially along track A, and a slide rail extending in the vertical direction is fixed on track A or track B, and a slider is slidably provided on the slide rail, and the slider is fixed on track B or track A; track A and track B are slidably connected by the slide rail and the slider to prevent track A from deviating and separating from track B.
[0007] As an optimization, track A is connected to track B through track C extending axially along track A, track C is fixed to track B, and track C is tilted downward toward one side of track A; track C is used to reduce the drop between the top of track A and the top of track B to prevent the rail car from damaging track A and track B.
[0008] As an optimization, through holes are opened in sequence on the fixed block along the axial direction of track A, and the through holes are symmetrically distributed about track A in the axial direction of track A; by arranging the through holes in sequence along the axial direction of track A, it is ensured that track A is subjected to uniform force in the axial direction of track A, thereby preventing track A from tilting, thereby affecting the detection results.
[0009] As an optimization, through holes are opened on the fixed block in sequence in the horizontal direction along the direction intersecting the axis of track A, and the through holes are symmetrically distributed about the axis of track A; the through holes symmetrically distributed about the axis of track A ensure that the force on both sides of track A is uniform, preventing track A from tilting, thereby causing the rail car to derail.
[0010] As an optimization, the end of the guide rail away from the spring passes through the through hole to be fixed with a limit block, and the distance between the end of the limit block away from the guide rod and the axis of the guide rod is greater than the aperture of the through hole; the limit block is used to prevent track A from warping.
[0011] As an optimization, a display screen is also included, which is electrically connected to the weighing sensor; the weight of the coal mine in the rail car is displayed in real time through the display screen.
[0012] As an optimization, an alarm device is also included, which is electrically connected to the weighing sensor; the alarm device is used to remind the staff in real time.
[0013] The beneficial effects of the utility model are as follows: the track A is connected to the base and shock-absorbing is performed through the fixing block, the guide rod and the spring, so as to prevent the track A from being separated from the base; the track A and the track B are slidably connected through the slide rail and the slider, so as to prevent the track A from being offset and thus being separated from the track B; the drop difference between the top of the track A and the top of the track B is reduced through the track C, so as to prevent the rail vehicle from causing damage to the track A and the track B; the through holes arranged in sequence along the axial direction of the track A ensure that the track A is uniformly stressed in the axial direction of the track A, so as to prevent the track A from tilting and thus affecting the detection result; the through holes symmetrically distributed about the axis of the track A ensure that the two sides of the track A are uniformly stressed, so as to prevent the track A from tilting and thus causing the rail vehicle to derail; and the limit block prevents the track A from tilting.
