The continuous rail track of combined type weighing device
The utility model belongs to the device of metering power or stress, and particularly the track weighing device is the device of the case weight of delaying unloading on the metering railroad track specifically.
The contained material of railway carriage measures with car in the railing, adopts a kind of so-called track weighing device.The track weighing device is divided into disconnected rail and two types on continuous rail.Disconnected rail type is a kind of traditional track weighing device, and its weighing precision is higher, but the cost height, long construction period.Constantly the rail type is a kind of track weighing device that grew up in recent years, and it is low that it has cost, characteristics such as short construction period, but its weighing precision is lower.Existing disconnected rail track weighing device mainly contains two kinds of forms, a kind of is the pressure type sensor of packing between rail and sleeper, when wheel from the rail through out-of-date, its weight affacts on the pressure type sensor by rail and measures, this mode since between weighing district and non-weighing district existence one zone of transition, thereby influence the raising of weighing precision.Another kind is with the part of rail as sensor itself, sensitive element is contained in the web of the rail place of one section rail both sides, when pressure wheel is between two sensitive elements, two sensitive elements just can come out the weight detecting on the wheel, the major defect of this mode be since rail below tie distance less, thereby effectively the weighing zone is too short, and this not only influences weighing precision, also limits its scope of application.
The purpose of this utility model is to provide manufacture craft simple for overcoming above-mentioned defective, and cost is low, a kind of continuous rail track weighing device that measuring accuracy is high.
The technical solution of the continuous rail track of the utility model combined type weighing device is to comprise rail and sensor, its special character is the auxilliary steel sleeper that is provided with below one section of railway track, pad is provided with the pad-board type sensor between steel sleeper and rail, is equiped with two pair filling type sensors corresponding to both sides, place, steel sleeper place in rail web of the rail place in one section front and rear part of described rail.
For being suitable for the weighing of different modes, described steel sleeper can be 1, and corresponding pad-board type sensor is 1 pair; Described steel sleeper also can be to be no less than 2, and corresponding pad-board type sensor is for being no less than 2 pairs.
The utility model is continuous rail track weighing device, so can overcome disconnected rail type track weighing device cost height, defectives such as long construction period.The utility model since below one section of rail the auxilliary steel sleeper that is provided with, pad is provided with the pad-board type sensor between steel sleeper and rail, be equiped with two pair filling type sensors corresponding to both sides, place, steel sleeper place in rail web of the rail place in one section front and rear part of rail, so, the pad-board type sensor can be measured the part of suffered weight on the track, the filling type sensor can be measured another part of suffered weight on the track, this part is to produce shearing force due to the Stress Transfer because of continuous rail between weighing district and the non-weighing district, so the utility model can be divided into dual mode with stressed returning on the track, add and calculate, it is big to have effective weighing zone, the characteristics that measuring accuracy is high, and can keep continuous rail weighing device cost low, the processing technology characteristic of simple.
The metering of this weighing device is that total shearing force (appropriately handling through signal) that general pressure that the pad-board type sensor is measured and filling type sensor are measured adds and obtains, that is:
, W is the loading weight on the Weighing Area,
Be i pad-board type sensor institute measuring pressure sum,
By j filling type sensor surveyed the shearing force sum.Like this, this weighing device is equivalent to form one " full floating weighing platform " in a certain section zone of rail, seemingly is same as disconnected rail type weighing device.The utility model Weighing Area length is got and is intended to used pad-board type number of sensors, and weighing precision depends on the precision of sensor.
Below in conjunction with description of drawings embodiment of the present utility model.

Embodiment 1 as shown in Figure 3.The continuous rail track of this routine combined type weighing device, auxilliary 7 steel sleepers 3 (replacing a regular sleeper) that are provided with above the roadbed below one section of railway track with this special steel sleeper, pad is provided with 7 to (each side 7 between steel sleeper 3 both ends and the rail 5, referring to Fig. 2) pad-board type sensor 3, be equiped with two pairs of filling type sensors 1 (each 1 of rail section front part sides in one section front and rear part of described rail in rail web of the rail place corresponding to both sides, place, steel sleeper 3 places, each 1 of both sides, rear portion are referring to Fig. 2).This device between two regular sleepers of not replacing 4, about 13 meters of its length.This device is suitable for railway carriage 6 car loads and weighs.
2 continuous rail tracks of routine combined type of embodiment weighing device, see Fig. 4, auxilliaryly above the roadbed below one section of railway track be provided with 2 steel sleepers 3, pad is provided with 2 to (each side 2 between steel sleeper 3 both ends and the rail 5, referring to Fig. 2) pad-board type sensor 3, be equiped with two pairs of filling type sensors 1 (each 1 of rail section front part sides, each 1 of both sides, rear portion are referring to Fig. 2) in one section front and rear part of described rail in rail web of the rail place corresponding to both sides, place, steel sleeper 3 places.About 3 meters of this device length is suitable for the railway carriage 6 bogies mode of weighing, and adds and gets general assembly (TW) front and back two bogies are stressed.
3 continuous rail tracks of routine combined type of embodiment weighing device, see Fig. 5, auxilliaryly above the roadbed below one section of railway track be provided with 1 steel sleeper 3, pad is provided with 1 to (each side 1 between steel sleeper 3 both ends and the rail 5, referring to Fig. 2) pad-board type sensor 3, be equiped with two pairs of filling type sensors 1 (each 1 of rail section front part sides, each 1 of both sides, rear portion are referring to Fig. 2) in one section front and rear part of described rail in rail web of the rail place corresponding to both sides, place, steel sleeper 3 places.About 1.5 meters of this device length is suitable for 6 modes of weighing of railway carriage, adds and gets general assembly (TW) 4 of front and back are stressed.
