For connecting hoisting line or hoisting chain 2 to be detected, the other end is provided with outer spiral shell for above-mentioned 3 one end of suspension centre screw rod
Line；Above-mentioned suspension centre 11 is connected with rack 1；Spring 5 is located in supporting sleeve 4, and its compressed length can be less than or equal to
The length of supporting sleeve 4, drift are greater than the length of supporting sleeve 4, and setting in this way is to be able to guarantee: in non-slack rope
When loose chain or disconnected rope chain rupture, spring 5 is compressed in supporting sleeve 4, and the both ends of supporting sleeve 4 are respectively the same as suspension centre 11 and trigger cap
6 are in contact, and trigger cap 6 is in a relatively fixed position；When slack rope pine chain or disconnected rope chain rupture occur, spring 5 bears weight
After the pressure of object disappears, trigger cap 6 under the action of restoring force, slides axially in spring 5 along suspension centre screw rod 3,6 energy band of trigger cap
The frizzen of dynamic fine motion detection switch 9 is swung.Referring to fig. 2, above-mentioned 3 other end of suspension centre screw rod sequentially passes through is arranged on suspension centre 11
First through hole, spring 5 the second through-hole being arranged and are stretched out after the internal thread hole of fixture nut 7 on trigger cap 6；Supporting sleeve 4
And spring 5 is installed between suspension centre 11 and trigger cap 6, fixture nut 7 and supporting sleeve 4 are respectively distributed to the two sides of trigger cap 6,
It is connected through a screw thread between fixture nut 7 and suspension centre screw rod 3, suspension centre screw rod 3 can be relative to above-mentioned first through hole and the second through-hole
It slides axially；Above-mentioned fine motion detection switch 9 is fixedly mounted in rack 1, and the frizzen and trigger cap of fine motion detection switch 9
6 are in contact.
In the present embodiment, to facilitate installation, fine motion detection switch 9 is fixedly mounted in rack 1 by mounting plate 10.?
In the present embodiment, preferably above-mentioned suspension centre 11 is the mounting rail that cross sectional shape is L-type；The L-type one side plate face and suspension centre of mounting rail
The axis of screw rod 3 is vertical, and above-mentioned first through hole is vertically set in the plate face；The L-type another side plate face and rack 1 of mounting rail are solid
Even；In this way, not only structure is simple, easy for installation, while its intensity is also higher.

It further include split pin 8；In the end point of above-mentioned 3 other end of suspension centre screw rod, it is disposed radially pin hole, split pin 8 is inserted into this
In pin hole.
Slack rope pine chain is carried out using slack rope pine chain provided by the utility model, disconnected rope broken chain detecting device, disconnected rope chain rupture is examined
When survey, it is a set of that the utility model detection device is all installed in each hoisting line or 2 end of hoisting chain, in this way, rising to each
Rope or hoisting chain 2 are all individually to detect again, can more accurately detect and judge the relaxation or crack conditions of certain root rope in this way.
Its specific work process are as follows: when hoisting line or hoisting chain 2 do not relax or are broken, hoisting line to be detected
Or hoisting chain 2 is tensioned under the action of weight, 4 both ends of supporting sleeve are in contact with suspension centre 11 and trigger cap 6 respectively, spring
5 are compressed, and the frizzen of fine motion detection switch 9 is in contact with trigger cap 6；When hoisting line or the relaxation of hoisting chain 2 or fracture,
The tension that hoisting line or hoisting chain 2 are born by weight disappears, and spring 5 reverts to free state by original compressive state,
Under the restoring force effect of spring 5, trigger cap 6 and suspension centre screw rod 3 are slided relative to the first through hole being arranged on suspension centre 11 along axial
Dynamic, in this way, trigger cap 6 drives the frizzen of fine motion detection switch 9 to swing, fine motion detection switch 9 can be obtained slack rope pine chain, break
The detection signal of rope chain rupture, and the detection signal is fed back into control device or display, loudspeaker of equipment etc. and is reminded
Device completes detection in this way.Operator according to detection the case where in time to relaxation or fracture hoisting line or hoisting chain
It is replaced, and then the generation of equal major accidents can be fallen to avoid weight.
Therefore, the slack rope pine chain of the utility model, disconnected rope broken chain detecting device can be widely applied to intelligent three-dimensional parking and set
In the lifting equipments such as the elevator in standby.
