Embodiment 1

[0028] refer to figure 1 , an elevator suspension rope tension measurement and adjustment mechanism, including a rope head screw 1, a rope head seat 3, an elastic element 5, a lock nut 7, a pressure sensor 9 and an adjustment nut 11.

[0029] The above-mentioned rope head screw 1, rope head seat 3 and elastic element 5 are the existing structure of the elevator, wherein the lower end of the rope head screw 1 is connected to the elevator suspension rope (not shown), and the rope head seat 3 is threadedly set on the rope head screw 1 , and the elastic element 5 is a compression spring, which is sheathed on the rope head screw 1 and located above the rope head seat 3 . The upper and lower ends of the elastic element 5 are provided with upper and lower spring pads 13 , 15 sheathed on the screw rod 1 , wherein the lower spring pad 15 is arranged between the elastic element 5 and the rope end seat 3 .

[0030] further reference figure 2 and Figure 5 , the lock nut 7 is threaded...

Embodiment 2

[0035] further reference Figure 8 and Figure 9 Compared with Embodiment 1, the tension measurement and adjustment mechanism of this embodiment is only slightly different in shape from the regulator 40 and the regulator 17 of the first embodiment, so only the regulator 40 is explained and omitted. Description of the remaining components.

[0036]The above-mentioned regulator 40 is roughly in the shape of a hollow cylinder and a section of circular arc is cut along its axial direction, thus forming a cylinder 42 , an irregular inner cavity 44 and a single adjustment window 46 . Likewise, its top end is provided with a plurality of adjustment holes 48 along its periphery. In this way, the adjuster 40 can also achieve the adjustment of the locking nut by opening an adjustment window 46 . Moreover, the adjuster 40 of this embodiment does not need to be inserted from the upper end of the screw rod 1 during assembly, but only needs to be installed from the side of the screw rod,...

Abstract

The invention discloses a tension measurement and regulation mechanism for a lift suspension rope. The mechanism comprises a screw, an elastic component, a locknut, a pressure sensor and a regulation nut, wherein the end of the screw is connected with the suspension rope, and the elastic component, the locknut, the pressure sensor and the regulation nut are arranged on the screw in a sleeving mode in sequence. The tension measurement and regulation mechanism for the lift suspension rope further comprises a regulator. The pressure sensor is arranged between the regulator and the regulation nut, the regulation nut is provided with a guiding portion, and the guiding portion is located between the screw and the pressure sensor. The tension measurement and regulation mechanism for the lift suspension rope is provided with the regulator and a regulation sleeve which are arranged on the periphery of the locknut in a covering mode, the locknut can be regulated conveniently and quickly, and the mechanism can be suitable for the locknuts with different specifications and sizes. Meanwhile, the special regulation nut is arranged, therefore, not only is output pressure of the pressure sensor more precise, but also the whole structure of the mechanism is simpler, and the production cost is more economical.

Description

technical field [0001] The invention relates to an elevator suspension rope tension measuring and adjusting mechanism. Background technique [0002] As we all know, the suspension ropes of the elevator car will have uneven tension after being used for a period of time, and this uneven tension will have a great impact on the performance of the elevator, the life of the suspension ropes and the sheave, such as It will cause the surface pressure of the rope groove of the traction wheel to be uneven. If the force is concentrated in a few rope grooves, the wear of the rope groove will be intensified; secondly, the elastic elongation of the suspension rope will be different due to the stress. , causing part of the suspension rope to change from static friction to sliding friction in the rope groove, thereby swallowing the material, affecting the comfort of the elevator car, and accelerating the scrapping speed of the suspension rope and traction sheave. Therefore, elevator manufa...
