Abstract
The utility model relates to a weighing device arranged on a top wheel of an elevator car, the structure of the utility model comprises a car lifting frame, the car top wheel, a car top wheel shaft, a strain foil sensor and a sensor bracket. The sensor is a strain foil weighing sensor, the middle of the strain foil weighing sensor is provided with an arc-shaped groove which is matched with the top wheel shaft, and the rigidity degree of the top wheel shaft in installation is increased. The interspace which is formed by the healing of the bracket below the sensor and the sensor is slightly bigger than the top wheel shaft, and the tightening extent of the healing of the bracket and the sensor does not affect the force reception of the sensor. The utility model has the working principles that the weighing device is not relate to the drag ratio of the elevator, the weight in the elevator car is increased by 1KG, and simultaneously, the force reception of the weighing sensor is also increased by 1KG and the measure precision is increased. The utility model has the working principles that the strain foil weighing sensor receives force when a cable wire drives the car top wheel and the car top wheel shaft to rotate and rises upwards, corresponding magnitude of voltage is exported and is changed into digital signals through counting and the present carrying capacity of the present elevator is prompted.
Description
Technical field
The utility model relates to a kind of weighting apparatus that is used for lift car top wheel, belongs to the isolated plant of measuring elevator load.
Background technology
Elevator is in operational process, and the in good time measurement of the load of weighing is taken turns on the lift car top, and is extremely important for the safe operation of elevator.With the large-tonnage elevator is example, the sensor that the measurement of the load of weighing of the above large-tonnage elevator of 1.5T is in the past adopted is mounted in the rope hitch plate place of elevator, in measurement process because the structure of the large-tonnage elevator all adopts traction ratio 2: 1 or 4: 1, when increasing 1kg in the car, the power that is reacted on the rope hitch plate has only 0.5kg or 0.25kg, the guide rail quantity of adding the large-tonnage elevator is more, 4 or 6 (normally being two) are arranged, so the friction force of car and guide rail increases, make its precision of mode of measuring the elevator load carrying ability at the rope hitch plate place can't reach the precision of elevator regulation, therefore the elevator load carrying ability can't accurately be measured, show and warning, often cause the elevator overload, can lead to a disaster when serious.
Summary of the invention
The purpose of this utility model is to provide a kind of Elevator Top Wheel Weighing Device, is used for the accurate measurement to lift car top wheel load, has overcome the defective of prior art.
Realize that the technical scheme that the purpose of this utility model is taked is such.Elevator Top Wheel Weighing Device of the present utility model comprises car suspension bracket, car roof wheel, car roof wheel shaft, also comprise strain chip LOAD CELLS and sensor bracket in the structure, be characterized in being with arc groove in the middle of the used sensor, institute's recessing and top wheel shaft match, firmness when increasing top wheel axle mounting, simultaneously, carriage below the sensor is just more bigger than top wheel shaft with the space that sensor closes up composition, make it can guarantee the stressed accurate measurement of car roof wheel, it is stressed that fastening degree does not influence sensor again.Principle of work of the present utility model is irrelevant with the traction ratio of elevator, and the weight in the lift car increases 1kg, and the stressed 1kg that also increases of LOAD CELLS has improved the precision of measuring greatly.
Can on carriage, install the link stopper structure additional for the horizontal string that prevents axle is moving.
Description of drawings
Fig. 1 is structural representation of the present utility model (shaft side figure).
Fig. 2 is a structure principle chart of the present utility model.
Fig. 3 is the front view of strain chip LOAD CELLS.
Fig. 4 is the birds-eye view of strain chip LOAD CELLS.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
The Elevator Top Wheel Weighing Device that provides referring to Fig. 1, wherein be with arc groove in the middle of the strain chip LOAD CELLS 2, be placed in the middle of car suspension bracket 1 and the carriage 4, institute's recessing and the top wheel shaft 3 (Fig. 1 that matches, shown in Figure 3), purpose is the firmness when increasing by 3 installations of top wheel shaft, carriage 4 below the sensor 2 has the groove that is complementary with top wheel shaft 3, the space that composition is closed up in 2 recessings of this groove and sensor just than the slightly larger in diameter of top wheel shaft 3 some, guarantee the stressed accurate measurement of car roof wheel, it is stressed that its fastening degree does not influence sensor 2 again, and top wheel shaft 3 is installed in 2 open arc connected in stars of strain chip LOAD CELLS and 4 recessings of carriage are closed up in the circular void of composition.With bolt 5 carriage 4, car roof wheel shaft 3 and strain-gauge LOAD CELLS 2 are fixed on the lift car suspension bracket 1.
For preventing the horizontal looseness of car roof wheel shaft 3, have limited impression at car roof wheel shaft 3 downsides, be provided with the projection that matches with car roof wheel shaft 3 downsides institute recessing at this device carriage 4 groove lowest parts, played preventing that car roof from taking turns the purpose of 3 left and right sides plaies.
The principle of work of this device is: when steel rope 7 drove 6 rotations of car roof wheel and upwards promotes, strain chip LOAD CELLS 2 was stressed, and output correspondent voltage value converts digital signal as calculated to, points out present lift car load carrying ability.
