Problems solved by technology

Although this device solves the problem of adjusting the tension force of the wire rope at the same time, a set of devices can be used multiple times, but it cannot actually measure the tension force of the wire rope. At the same time, the device is relatively complicated and needs to provide a hydraulic power source, etc., and it is inconvenient to carry

Embodiment 1

[0028] like Figure 2 to Figure 4 As shown, an elevator wire rope tension detection and adjustment device according to the present invention is mainly composed of a pressure sensor 1, a pressure sleeve 2 and a pressure sleeve displacement adjustment assembly.

[0029] The central part of the pressure sensor 1 is provided with a through hole 11 . The pressure sensor 1 is slidably sleeved on the pull rod 41 through the through hole, and its lower end surface fits on the upper end surface of the spring upper seat 44 . The diameter of the perforation 11 should be greater than the maximum dimension of the outer diameters of the locking nut 42 and the tightening nut 43 . In addition, the pressure sensor can be a wireless pressure sensor with a built-in wireless transmission module of the battery box, and a handheld mobile terminal for receiving and displaying pressure information is equipped corresponding to the wireless pressure sensor. The pressure sensor can also be a wired pre...

Embodiment 2

[0037] like Figure 5 to Figure 7 As shown, an elevator wire rope tension detection and adjustment device according to the present invention is mainly composed of a pressure sensor 1 , a pressure sleeve 2 , a pressure sleeve displacement adjustment assembly and a control device 36 .

[0038] The central part of the pressure sensor 1 is provided with a through hole 11 . The pressure sensor 1 is slidably sleeved on the pull rod 41 through the through hole, and its lower end surface fits on the upper end surface of the spring upper seat 44 . The diameter of the perforation 11 should be greater than the maximum dimension of the outer diameters of the locking nut 42 and the tightening nut 43 .

[0039] The pressure sleeve 2 is as image 3 As shown, it is cylindrical, and an axial through hole 21 is opened on it. The pressure sleeve is slidably sleeved on the pull rod 41 through the axial through hole, and its lower end surface is attached to the upper end surface of the pressure ...

Abstract

The invention discloses an elevator steel cable tension detecting and regulating device. The elevator steel cable tension detecting and regulating device is installed on a cable head component of an elevator steel cable; the cable head component comprises a pull rod, a spring upper base, a locknut and a tightening nut; the elevator steel cable tension detecting and regulating device comprises a pressure sensor, a pressing sleeve and a pressing sleeve displacement regulating component, wherein the pressure sensor can be slidably arranged on the pull rod in a sleeving manner via a penetrating hole in the pressure sensor; the lower end face of the pressure sensor clings to the upper end face of the spring upper base; the pressing sleeve can be slidably arranged on the pull rod in a sleeving manner via an axial through hole formed in the pressing sleeve; the lower end face of the pressing sleeve is connected with the pressure sensor; the side elevation surface of the pressing sleeve is provided with gaps for operation of a nut screwing tool corresponding to the locknut and the tightening nut; and the pressing sleeve displacement regulating component is arranged in the pull rod above the pressing sleeve and is used for regulating the displacement of the pressing sleeve on the pull rod. The elevator steel cable tension detecting and regulating device disclosed by the invention can beused for effectively detecting and regulating the tension of the steel cable in a high precision manner, and is relatively simple in structure, convenient to operate and relatively low in manufacturing cost.

Description

technical field [0001] The invention belongs to the technical field of elevators, and in particular relates to a tension detection and adjustment device for elevator steel wire ropes. Background technique [0002] In the existing elevators, the elevator car and the counterweight are mainly connected by wire ropes, and the up and down movement of the car is realized under the drive of the traction machine. In order to ensure the smooth and safe operation of the elevator, the wire ropes must be consistent. tension. like figure 1 As shown, the rope heads of each steel wire rope 5 of the existing elevator are suspended and fixed by the rope head assembly 4, and the rope head assembly mainly consists of a pull rod 41, a locking nut 42, a tightening nut 43, an upper spring seat 44, a compression spring 45, a lower Spring seat 46, rope head plate 47, rope head taper sleeve 48 are formed, and the tension adjustment of steel wire rope is mainly realized by the compression of regula...
