Abstract
The utility model provides a firm formula developments track scale, it includes cushion, a supporting beam, rail, skeleton pole, gravity sensor, screw, rail slot, its characterized in that of: be equipped with columniform skeleton pole at a supporting beam's both ends, a supporting beam both ends is equipped with long cubic's cushion, and skeleton pole parcel is lived to the cushion, and a supporting beam top is equipped with two rail slots that are parallel to each other, and rail slot bottom all is equipped with gravity sensor, and the rail is installed to the gravity sensor top in the rail slot, and the rail passes through the fix with screw on a supporting beam. Technical scheme's beneficial effect is more than adopting: this track scale adopts the structure of simple two cushion of supporting beam collocation, can fix on the rail road bed firmly, improves the bearing capacity of track scale. Adopt the fixed rail of rail slot on the supporting beam, can prevent effectively that the rail atress is crooked. Install gravity sensor inside the rail slot, can effectively prevent external influence to gravity sensor measurement accuracy.
Description
Technical field
This utility model relates to field of measuring techniques, particularly a kind of firm formula dynamic railway truck scale.
Background technology
Track scale is the weighing apparatus weighing railway freight-car load-carrying, and point static state railroad track scale, dynamic railway truck scale and railway weigh three kinds.Dynamic railway truck scale is the measuring equipment that the rolling stock in advancing low speed is weighed, and dynamic railway truck scale is widely used in the weighing to railcar bulk goods of factory, mine, metallurgy, foreign trade and railway interests.Existing dynamic railway truck scale designs complexity mostly, have employed too much beam structure, causes rail when carrying heavier rolling stock, and crossbeam bears bigger pressure, reduces the service life of track scale.Gravity sensor is mounted directly in orbit by most of dynamic railway truck scales, causes it to be exposed to the external world, influences whether its precision detected after using overlong time.
Summary of the invention
The purpose of this utility model be to provide a kind of by steel rail laying in the rail slot at support beam top, support beam two ends arrange the cushion block that concrete cement manufactures, thus increase the steadiness of this track scale, and gravity sensor is arranged in rail slot, ensure the firm formula dynamic railway truck scale of the susceptiveness of gravity sensor.
This utility model is realized in, it includes cushion block, support beam, rail, frame rod, gravity sensor, screw, rail slot, it is characterized in that: be provided with the frame rod of cylinder at the two ends of support beam, support beam two ends are provided with the cushion block of cuboid, frame rod is wrapped by cushion block, support beam top is provided with two rail slots being parallel to each other, it is equipped with gravity sensor bottom rail slot, gravity sensor in rail slot is arranged above rail, and rail is fixed by screws in support beam.
Optimizing further as the technical program, described support beam and frame rod are by the steel alloy manufacture of trade mark U77MnCr.
As the further optimization of the technical program, described support beam and frame rod are monolithic construction.
As the further optimization of the technical program, described cushion block is manufactured by concrete cement, and the thickness of cushion block is more than the thickness of support beam.
As the further optimization of the technical program, described rail and the mutual interference fits of rail slot of support beam.
Above technical scheme is used to provide the benefit that: the support beam two ends of this firm formula dynamic railway truck scale are provided with frame rod, support beam two ends are provided with cushion block, support beam top is provided with two rail slots being parallel to each other, it is equipped with gravity sensor bottom rail slot, rail is installed in rail slot, and rail is fixed in support beam by some screws.This track scale uses simple support beam to arrange in pairs or groups the structure of two cushion blocks, can be firmly secured on rail subgrade, improve the weight capacity of track scale.Use the rail slot in support beam to fix rail, can effectively prevent forces acted on rail crooked.Gravity sensor is arranged on inside rail slot, can effectively prevent the impact of extraneous counterweight force sensor measuring precision.
Accompanying drawing explanation
Hereinafter below in conjunction with the accompanying drawings this utility model is done further detailed description；
Fig. 1 is the structural representation of firm formula dynamic railway truck scale；
Fig. 2 is the sectional view of A-A direction shown in Fig. 1.
Detailed description of the invention
As shown in Fig. 12, this firm formula dynamic railway truck scale includes cushion block 1, support beam 2, rail 3, frame rod 4, gravity sensor 5, screw 6, rail slot 7, this firm formula dynamic railway truck scale includes the support beam 2 of some rectangular strips, the frame rod 4 of cylinder it is provided with at the two ends of support beam, support beam 2 two ends are provided with the cushion block 1 of cuboid, frame rod is wrapped by cushion block 1, support beam top is provided with two rail slots 7 being parallel to each other, gravity sensor 5 it is equipped with bottom rail slot 7, gravity sensor in rail slot 7 is arranged above rail 3, and rail 3 is fixed in support beam by screw 6.After rail vehicle low speed presses through rail 3, gravity is passed to gravity sensor 5 by rail 3, and gravity sensor 5 just can carry out weighing operation to rail vehicle.
Support beam 2 and frame rod 4 are by the steel alloy manufacture that the trade mark is U77MnCr, and firm in structure, anti-wear performance is good, and support beam 2 and frame rod 4 are monolithic construction, can produce by the way of solid forging.
Cushion block 1 is manufactured by concrete, and cushion block 1 and frame rod 4 constitute armored concrete formula structure, have high hardness, improve the weight capacity of this track scale, and the thickness of cushion block 1 is more than the thickness of support beam 2, cushion block 1 is laid on rail subgrade, can effectively support support beam 2.Rail 3 and the mutual interference fits of rail slot 7 of support beam 2, coordinate closely, then provide pretightning force by screw 6, tightly fix rail 3, can effectively prevent rail 3 from rocking in rail slot 7, improve the steadiness of this track scale.
This track scale uses simple support beam 2 to arrange in pairs or groups the structure of two cushion blocks 1, can be firmly secured on rail subgrade, improve the weight capacity of track scale.Use the rail slot 7 in support beam 2 to fix rail 3, can effectively prevent rail 3 stress crooked.Gravity sensor 5 is arranged on rail slot 7 internal, can effectively prevent the extraneous impact on gravity sensor 5 certainty of measurement, increase the service life of this track scale.
