Further, every group of guide wheel assembly all includes a pair of orthogonal pulley, and the two of guide wheel assembly and back-end support
The surface contact of root post.
Further, four groups of pulleys are equipped with around the carrying platform.
Further, surface of the four groups of pulleys of the carrying platform respectively with stent four columns contacts.
The beneficial effects of the utility model are：The utility model coordinates data acquisition using the sensor containing foil gauge
Instrument, can calculate the elongation of belt according to the change of resistance of sensor, and can interpolate that the elongation of belt at this time whether
In safe range, if having the danger of fracture, and belt fracture early warning can be sent so that maintenance personnel can be in sufficient, peace
Equipment is carried out maintenance in full time range, so as to reduce equipment failure rate, avoids losing caused by belt fracture.

Embodiment
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, a kind of elevator for possessing belt fracture warning function, including belt 1, roller 3 and motor
4, the roller 3 is installed on stent 8, and for the belt 1 around the home on roller 3, one end of belt 1 connects carrying platform 6, belt
1 other end connection balance weight assembly 5,4 driving drum 3 of motor, roller 3 drives belt 1 to act, under the connection of belt 1,
Balance weight assembly 5 and carrying platform 6 can carry out lifting action, along the direction uniform intervals implantation of 1 length of belt in belt 1
Sensor group 2, sensor group 2 access data collecting instrument 7 after connecting, and the sensor group 2 is the sensor containing foil gauge.Should
The resistance value of sensor containing foil gauge can change with the deformation of belt 1, and can be by the change of the resistance value with telecommunications
Number form output.
The data collecting instrument 7 includes alarm module, and when belt 1 is in risk of breakage, data collecting instrument 7 can start
The alarm module.
The sensor group 2 is symmetrical as symmetry axis using the longitudinal centre line of belt 1, and in each sensor group 2
Sensor quantity depending on the width of belt 1.The width of belt 1 in specific embodiment of the utility model is
180mm, using the distance between two sensors, described two sensors is about the one of 1 width of belt in each sensor group 2
Half.It can prevent that there are larger because belt 1 causes there are non-uniform deformation the data that sensor group 2 gathers using this design
Error.
The stent 8 includes four columns, and guide wheel assembly 5-1 is equipped with around balance weight assembly 5.Every group of guide wheel assembly
5-1 includes a pair of orthogonal pulley, and guide wheel assembly 5-1 is contacted with the surface of the two root posts of 8 rear end of stent.It is described to hold
Four groups of pulleys are respectively provided with around carrying platform 6.Surface of the four groups of pulleys of carrying platform 6 respectively with the four columns of stent 8 connects
Touch.
The principle of the utility model is：
When carrying platform 6 carries out elevating movement, belt 1 can be stretched, and the resistance value of sensor group 2 can be because belt 1
Deformation and change, data collecting instrument 7 gathers the resistance variations of sensor group 2 and analysis calculates the elongation of belt 1, data
Acquisition Instrument 7 by the elongation of the belt 1 calculated compared with the elongation of the normal range (NR) of belt 1, once calculate
The elongation of belt 1 exceedes normal range (NR), and data collecting instrument 7 starts alarm and sends alarm, shows that belt 1 is in fracture at this time
Danger in.The utility model reduces the difficulty of 1 elongation of hand inspection belt, operating personnel only need to according to alarm sound into
Row emergency processing, while sufficient safety time is provided for emergency processing operation, avoid the post-rift corrective operation institute of belt 1
Caused by security risk, saved financial cost, ensured production safety.
In a particular embodiment, the total length of belt 1 is L, is grown when belt 1 does not deform upon in belt 1 along belt 1
The direction of degree is with the spacing distance uniform intervals implanted sensor group 2 of A length, and wherein sensor group effective length is P, and data are adopted
Collection instrument 7 gathers the data of N number of sensor group 2 close to 6 position of carrying platform.The data collecting instrument 7 when belt 1 does not deform upon
The internal resistance of the N number of sensor group 2 collected is R, which can perceive the deformation quantity of the belt 1 of N*A length.Work as skin
When 1 stress of band stretches, the variable quantity of the internal resistance for N number of sensor group 2 that data collecting instrument 7 collects is Δ R, N number of sensor
The deformation quantity for the belt 1 that group 2 can perceive N*A length is N* Δs A.Due toWherein k is sensor
The sensitivity coefficient of middle foil gauge, the sensitivity coefficient are provided by sensor producer, the k=2 in specific embodiment of the utility model.
Therefore, the elongation total amount for the belt 1 that total length is L is：Data collecting instrument 7 by the elongation of the belt 1 calculated with
1 elongation of belt in data collecting instrument 7 in default safe range is made comparisons, and is preset if the actual elongation of belt 1 is more than
Safe range in 1 elongation of belt, data collecting instrument 7 start alarm send alarm.
