Abstract

The utility model relates to a tramway weighing apparatus adopts no girder structure, and the track scale is a whole, comprises balance body frame, built -in sensor and protection casing, balance body frame is anti -creep frame structure, evenly sets up a plurality of briquettings on the balance body frame of anti -creep frame structure, makes the track scale balance body and rail zonulae occludens through the fastening briquetting during attachment rail weighing apparatus, and the one end of frame sets up the anticreeper, prevents the rail drunkenness, evenly arranging on the frame and cuting force transducer and press force transducer, the frame upper surface covers the protection casing, open a plurality of air -out through hole on the balance body frame, the through -hole is beaten in the inessential position of frame, is used for exhausting during installation grout to frame the following is in the milk unreally. Process the equipment in the factory, let back integral hoisting transport. During on -the -spot installation, only need lay the mine car weighing apparatus in the foundation ditch, adjust the weighing platform after, utilize support cement to carry out secondary grouting, can influence the railway transportation because of the civil engineering overlength, simultaneously construction cost sparingly. The measurement of mainly used mine car, occasions such as the adaptation is hanged down in the mine load, environment complicacy are used.

Description

A kind of tramroad weighing apparatus

Technical field: the utility model technology relates to a kind of track scale, especially for the track scale of mining car measurement.

Background technology: the features such as operating environment dust is large, slag class foreign matter is many, moist generally will be considered with track scale in mine, when general installation simultaneously, need to build concrete pedestal railway roadbed, this huge civil engineering quantities is large, construction cost is high, construction period needs to seal for a long time line in length, work progress, has brought very large inconvenience to transport.

Summary of the invention: for these drawbacks, the utility model provides a kind of tramroad weighing apparatus, adopts without girder structure, and track scale is as a whole, is made up of scale body framework, sensor and protective cover; Scale body framework is anti-frame climbing structure, on framework, evenly arrange pressure sensor and shear force sensor, frame upper surface covered protection cover, protective cover adopts compared with steel plate, can prevent that in use bogie truck off-road injures sensor by a crashing object, pressure sensor and shear force sensor are carried out to integral protection, not only ensured traffic safety but also ensured accurate measurement.

On the scale body framework of anti-frame climbing structure, multiple briquettings are evenly set, when attachment rail weighing apparatus, by fastening briquetting, track weighing platform are closely connected with rail, one end of framework arranges anticreeper, prevents rail play.

The contact-making surface of track weighing platform framework and rail arranges rubber slab, insulation board and nylon backplate. Rail is placed on framework, between rail foot surface and framework, use rubber slab, briquetting is pushed down the position between pad insulation board of rail, nylon backplate is installed below briquetting, be used for preventing that rail from jumping, ensureing that rail both sides security bar does not run, meet the requirement of assemblage gap and insulation simultaneously, had above-mentioned insulation board and nylon backplate, just can ensure between rail in state of insulation. Rubber slab does not need mold customized, is directly cut into square plate by size and is padded under rail.

On scale body framework, insulated isolation cover is set, shear force sensor is placed in insulated isolation cover inside. Because shear force sensor circuit middle part has one to be circular steel plate, if put bad rail will being connected with framework, so employing insulated isolation cover, insulated isolation cover is open and clear pipe, interior pad insulation board, circular shear force sensor steel plate is placed in cover, has avoided having influence on pressure sensor because of shear force sensor conduction.

On scale body framework, open multiple through holes, for exhaust. Through hole is beaten in the inessential position of framework, when grouting is installed be used for exhaust, in order to avoid it is unreal to be in the milk under framework bottom.

On scale body framework, there is penetration pipe. Be convenient for changing sensor.

Track scale install basis in pre-buried walk spool, cement surface give prominence in one end, the other end cause understands foundation ditch. Facilitate cabling and covering.

Owing to adopting technique scheme, the utility model is compared original structure mine car scale, can simplify foundation ditch, saves solid concrete roabed and spandrel girder, the coupling part of weighing-rail and approach rail is away from weighing district, has the advantages such as the few and on-the-spot installation of the civil engineering costs, machining amount of saving is fast. Processing assembling is all to carry out in factory, then integral hoisting transport. When on-the-spot installation, only mine car scale need be placed in foundation ditch, adjust after weighing platform, utilize bearing cement to carry out back-grouting, can not affect railway transportation because of civil engineering is long, save construction cost simultaneously.

Detailed description of the invention: as shown in Figure 1, Figure 2, Figure 3 shows, tramroad weighing apparatus adopts without girder structure, and track scale is as a whole, is made up of scale body framework 1, built-in sensors and protective cover 7; Scale body framework 1 is anti-frame climbing structure, on the scale body framework 1 of anti-frame climbing structure, multiple briquettings 4 is evenly set, and when attachment rail weighing apparatus, by fastening briquetting 4, track weighing platform is closely connected with rail, and one end of framework 1 arranges anticreeper 8, prevents rail play; On framework 1, evenly arrange shear force sensor 2 and pressure sensor 3, framework 1 upper surface covered protection cover 7;

As shown in Figure 4, at track weighing platform framework 1 and the contact-making surface of rail, nylon backplate 9, rubber slab 10 and insulation board 11 are set, rail is placed on framework 1, between rail foot surface and framework 1, pad rubber slab 10, briquetting 4 is pushed down the position between pad insulation board 11 of rail, nylon backplate 9 is installed below briquetting 4, and rubber slab 10 does not need mold customized, is directly cut into square plate by size and is padded under rail.

As shown in Figure 5, on scale body framework 1, insulated isolation cover 6 is set, insulated isolation cover 6 is open and clear pipe, interior pad insulation board, and the circular steel plate of shear force sensor is placed in cover, has avoided having influence on pressure sensor because of shear force sensor conduction.

As shown in Figure 6, open multiple exhaust holes 12 on scale body framework 1, through hole is beaten in the inessential position of framework 1, when grouting is installed be used for exhaust, in order to avoid it is unreal to be in the milk under framework bottom.

As shown in Figure 3, on scale body framework 1, there is penetration pipe 5, be convenient for changing sensor.

As shown in Figure 7, track scale install basis in pre-buried walk spool 13, cement surface give prominence in one end, the other end cause understands foundation ditch 14, facilitate cabling and covering.
