Embodiment 1

[0039] Such as Figure 6 , Figure 7 As shown, the base plate 1 is a knife handle-shaped plate, the part with the lower convex edge 3 on the base plate 1 is the fixed connection part, and the part suspended at the bottom is the suspended extension part. An oblong transverse through hole 4 (or oval or elongated hole type) is opened at the lower part of the suspended extension part to pass through the hinge shaft 10 of the brake arm. The tension and pressure sensors 2 are respectively attached on the substrate and the lower edge of the suspended extension ( Figure 6 ), preferably close to the root of the knife handle, to detect the tension and compression force on the substrate when the brake is applied. The tension and pressure sensors 2 can also be respectively attached to the substrate surface of the suspended extension ( Figure 7 ).

Embodiment 2

[0041] Such as Figure 8 — Figure 11 As shown, the shape of the substrate 1 is similar to that of Embodiment 1. On the suspended extension of the substrate 1, there are vertical upper and lower through grooves 5 near the plate body of the fixed connection portion. Grooving on both sides of the board can also be done symmetrically on both sides of the board. The tension and pressure sensors 2 are respectively attached to the upper and lower edges of the plate body at the notch of the upper and lower through grooves ( Figure 8 , Figure 9 ) to detect the tension and compression force on the substrate 1 when the brake is applied. The tension and pressure sensor 2 can also be respectively attached to the upper and lower ends of the groove bottom surface of the upper and lower through grooves 5 ( Figure 10 , Figure 11 ).

Embodiment 3

[0043] Such as Figure 12 , Figure 13 As shown, the shape of the substrate 1 is similar to that of Embodiment 1, and an upper flat groove 7 and a lower flat groove 9 are opened on the plate body of the suspended extension part of the substrate close to the fixed connection part, and the upper flat groove 7 and the lower flat groove 9 face away from each other up and down. The tension and pressure sensors 2 are respectively attached to the groove bottom surface of the upper flat groove 7 and the groove bottom surface of the lower flat groove 9 ( Figure 12 ) to detect the tension and compression force on the substrate 1 when the brake is applied. The tension-compression sensor 2 can also be respectively attached on the base plate body near the port of the upper flat groove and the port of the lower flat groove, and the tension-compression sensor 2 is on a vertical line with the upper flat groove and the lower flat groove ( Figure 13 ).

Abstract

The invention relates to a hub type brake braking torque true value detection sensor and a braking torque true value detection method. The hub type brake braking torque true value detection sensor comprises a base plate used for being fixed to a brake base and a tension and compression sensor attached to the base plate; the base plate is divided into a suspending extending part of which the bottomside is suspended and a fixed connecting part fixedly connected with the brake base, the suspending extending part of the base plate is provided with a transverse through hole, and the transverse through hole is used for a braking arm hinging shaft of a hub type brake to penetrate through to convert perpendicular acting force generated when a braking arm brakes into tension and compression actingforce to the base plate through the braking arm hinging shaft; the tension and compression sensor is attached to the suspending extending part at the portion, between the transverse through hole andthe fixed connecting part, on the base plate to be used for detecting the tension and compression acting force exerted on the base plate, and then through the geometric size of a braking drum installed on hoisting equipment of the hub type brake, the braking torque true value of the hub type sensor is obtained through calculation.

Description

technical field [0001] The invention relates to a sensor, in particular to a sensor for detecting the true value of the braking torque of a hub type brake and a method for detecting the true value of the braking torque. Background technique [0002] In the current urban construction, high-rise buildings have sprung up on the vast expanse of land, and several elevators must be installed in each high-rise building to transport people and goods, and the traction device on the elevator - the elevator traction Most traction machines use hub brakes for traction and braking. [0003] An important indicator of the stable working performance of the hub brake is the braking torque. As long as the brakes can maintain sufficient braking torque, effective braking can be implemented. And once the braking torque is insufficient, the braking effect of the hub type brake will be invalidated, and its consequence is exactly the occurrence of a vicious event that directly causes the ladder to...
