Abstract

The invention discloses an elevator steel wire rope tension detection device, which comprises a bracket, wherein the upper end and the lower end of the bracket are respectively fixed with a connection plate, the side of each connection plate is fixed with a semi-circle part with a rope groove, the middle of the bracket is hinged with the middle of a rotating bar, one end of the rotating bar is installed with a digital display torque wrench, the other end of the rotating bar is installed with a rolling wheel with the rope groove, and the bracket is also installed with a limiting device for limiting the position of the digital display torque wrench. The elevator steel wire rope tension detection device disclosed by the invention is high in detection accuracy and low in manufacture cost.

Description

The elevator wire rope tension detecting apparatus

Technical field

The present invention relates to a kind of tension detecting apparatus, particularly a kind of elevator wire rope tension detecting apparatus.

Background technology

At present elevator wire rope tension force being detected, generally all is manual sensation, and whether can accurately not draw every steel wire rope tension even; Its accuracy, security are all lower comparatively speaking; A kind of in addition is the Electronic Testing device, and price comparison is high comparatively speaking, and economic performance is lower.

Summary of the invention

The present invention seeks to:, a kind of accurate, cheap elevator wire rope tension detecting apparatus that detects is provided to the problems referred to above.

Technical scheme of the present invention is: a kind of elevator wire rope tension detecting apparatus; Comprise support, the two ends up and down of this support all are fixed with web joint, and the sidepiece of each web joint all is fixed with the semicircle spare of band grooving; The middle part of said support and the middle part of swingle are hinged; One end of this swingle is equipped with the digital display torque spanner, and the other end of this swingle is equipped with the roller of band grooving, and the stop means that is used to limit said digital display torque spanner position also is housed on the said support.

As preferably, said support and web joint are sheet metal component.

As preferably, said semicircle spare is fixing with the web joint welding.

As preferably, said web joint is through being bolted on the support.

Advantage of the present invention is: this elevator wire rope tension detecting apparatus provided by the invention, can judge each the root steel wire rope tension reasonably stability whether on the elevator through the data that draw on the digital display torque spanner, and its accuracy is high, and cost is lower.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the present invention is further described:

Fig. 1 and Fig. 2 are the structural representation of this elevator wire rope tension detecting apparatus;

Wherein: 1-semicircle spare, 2-swingle, 3-support, 4-web joint, 5-digital display torque spanner, 6-roller, 7-stop means, 8-wire rope, 9-grooving.

Embodiment

As shown in Figure 1, the elevator wire rope tension detecting apparatus of present embodiment comprises support 3, and all there is web joint 4 at the two ends up and down of support 3 through bolt, and the support 3 in the present embodiment is sheet metal component with web joint 4.The sidepiece of each web joint 4 all is welded with the semicircle spare 1 of band grooving 9.The middle part of the middle part of said support 3 and a swingle 2 is hinged, and an end of said swingle 2 is equipped with digital display torque spanner 5, and the other end of said swingle 2 is equipped with the roller 6 that also has grooving 9.

In addition, this example also is equipped with the stop means 7 that is used to limit said digital display torque spanner position on said support 3, and the angle that stop means 7 can make digital display torque spanner 5 pull at every turn is identical, thereby be convenient to the operator testing result of many steel wires is compared.

The method of application of present embodiment elevator wire rope tension detecting apparatus comprises following three big steps:

The fixed mount 3 of step 1, hand-held this device makes an elevator wire rope 8 to be detected between semicircle spare 1 and fixed mount 3, and makes this wire rope 8 be close to grooving 9 on two semicircle spares 1 but do not stress, like Fig. 1.

Step 2, pull digital display torque spanner 5 then swingle 2 is rotated, be against (the twisting amplitude of stop means restriction digital display torque spanner) on the stop means 7 until digital display torque spanner 5.This moment, the roller 6 of swingle 2 ends can withstand wire rope 8 side shifting (wire rope is pasting the grooving on the roller) outside support; Make wire rope 8 bend (like Fig. 2); Can produce acting force by pair roller 6 after wire rope 8 bendings; This acting force can be delivered to digital display torque spanner 5, and the user can directly read the tension data of wire rope 8 from digital display torque spanner 5, like Fig. 2.And the operator can detect the tension data of diverse location on the same wire rope through moving the vertical position of this pick-up unit.

The operation of step 3, repeating step one and step 2 detects by root many wire rope on the elevator.Because the existence of stop means 7, when the operator detected every steel wire, the amplitude of pulling of digital display torque spanner 5 all was the same, also all was the same thereby make the flexibility of every wire rope when detecting.If the tension data that every wire rope detects all is a numerical value or very approaching, explain that these steel wire rope tensions are stable, stressed evenly; If the tension data that these wire rope detect differs bigger, these wire rope discontinuity are described, the wire rope easy abrasion needs to regulate wire rope.

Certainly, the foregoing description only is explanation technical conceive of the present invention and characteristics, and its purpose is to let people can understand content of the present invention and implements according to this, can not limit protection scope of the present invention with this.The all spirit of main technical schemes is done according to the present invention equivalent transformation or modification all should be encompassed within protection scope of the present invention.
