Described hoist ropes is one, is the closed winding, and its two ends all are connected on cage or the counterweight, and counterweight or cage then are arranged on the middle part of this root hoist ropes, thereby this root hoist ropes is divided into tension section and hangs section; This tension force detection and safety device are arranged on the two ends of described hoist ropes.
Described hoist ropes is two, and one its two ends are connected on cage and the counterweight as suspension strop, and another root is as tensioned lines, and its two ends are connected on cage and the counterweight equally; Arbitrary end at these two hoist ropes is provided with this tension force detection and safety device simultaneously.
The tension force of the end direct perception hoist ropes of the utility model by touch structure being arranged on described hoist ropes can be arranged on cage or the counterweight easily, can be when elevator is worked along with cage or counterweight lifting, conveniently install, debugging and maintenance; And can simplified structure.
Description of drawings
Fig. 1 is the structural representation of hoist ropes tensioning state of the present utility model.
Fig. 2 is the structural representation of hoist ropes relaxed state of the present utility model.
Fig. 3～5 are the application of the utility model in several different windings of hoist ropes.
Among the figure: 1-hoist ropes, 2-touch structure, 3-pressure spring, 4-touch part, 5-travel switch, 6-instruction unit, 7-elastic force scale, 8-support portion, 9-tension adjustment nut, M-cage or counterweight; The 31-hoist ropes, 32-traction sheave, 33-cage, 34-counterweight, 35-elevator platform; The 41-hoist ropes, 41a-hoist ropes tension section, the 41b-hoist ropes hangs section, 42-traction sheave, 43-cage, 44-counterweight, 45-elevator platform; The 51a-tensioned lines, 51b-suspension strop, 52-traction sheave, 53-cage, 54-counterweight, 55-elevator platform.
The specific embodiment
The tension force of hoist ropes as shown in Figure 1 detects and safety device, comprise that roughly is a "T"-shaped touch structure 2, a pressure spring 3, an elastic force scale 7 and a travel switch 5: pressure spring passes in the bar portion (vertical part) of touch structure, one end of hoist ropes 1 passes the support portion 8 that is fixed on cage or the counterweight M is connected touch structure according to the mode of conveniently separating rope bar portion (vertical part), when regulating the tension hoist ropes by the tension adjustment nut on the touch structure thus, spring is compressed, described touch structure is remained on tension force perception state, be convenient to determine the tension force of hoist ropes by the position of instruction unit (end of touch structure transverse part) 6 on elastic force scale 7 (being fixed on cage or the counterweight).
As shown in Figure 2, in case hoist ropes 1 tension force is because of some factor (as lax, fracture etc.) when reducing, pressure spring 2 promptly orders about the touch part 4 (other end of touch structure transverse part) of touch structure, set according to calculating, when hoist ropes 1 tension force was reduced to a certain degree, travel switch 5 was promptly touched in the touch part 4 of touch structure, stopped operating by travel switch 5 control towing machines, in time overhaul and debug, the accident that prevents takes place.
Shown in Figure 3 is a kind of winding of hoist ropes: hoist ropes 31 is one, and its two ends are walked around traction sheave 32 and hung cage 33 and counterweight 34 respectively; According to this structure, detection of the tension force of the hoist ropes shown in Fig. 1,2 and safety device can be arranged on arbitrary end of hoist ropes, do not repeat them here.
