Example 1
Referring to fig. 1 and 2, an automatic tension adjustment rope hitch system for an elevator hoist includes a first rope hitch 1, a second rope hitch 2, and a plurality of hoist ropes 3. The first rope hitch 1 and the second rope hitch 2 each comprise a base 4 and a chain rope hitch assembly 5. Two shaft seats 41 are vertically arranged on the base 4, and a rotating shaft 42 is horizontally arranged between the two shaft seats 41. N or n+1 chain rope end components 5 are arranged on the rotating shaft 42 of the first rope end device 1at intervals. Generally, there are at least 3 hoisting ropes 3, so N is not less than 1 and is a natural number. The chain rope head assembly 5 comprises a shaft sleeve sleeved on the rotating shaft 42 and a chain 51 wound on the shaft sleeve, and the shaft sleeve is fixedly connected with the rotating shaft 42 and can synchronously rotate along with the rotating shaft 42. The shaft sleeve is provided with a sprocket, and the chain 51 is meshed with the sprocket and can rotate synchronously with the rotating shaft 42. In specific implementation, the shaft sleeves are uniformly distributed on the rotating shaft 42 and limited by the positioning sleeve, so that the tension of each traction rope 3 can be ensured to be consistent. The two ends of the chain 51 are respectively connected with one end of a connecting screw rod 52, and the other end of the connecting screw rod 52 passes through the base 4 and then is connected with a chain rope head 53. The chain rope head 53 comprises a taper sleeve 7, and a clamping wedge block 8 is arranged in the taper sleeve 7. In practice, the chain rope head 53 further comprises a connecting sleeve 531. A locking nut 521 and an adjusting nut 522 are sleeved on one end of the connecting screw 52 far away from the chain 51, and then extend into one end of the connecting sleeve 531 and are in threaded connection with the connecting sleeve 531. The other end of the connecting sleeve 531 is connected with the taper sleeve 7 through a connecting bolt 532. In this way, the tension of one wire rope can be adjusted by adjusting the nut 522, and after the adjustment is completed, the wire ropes are locked by the locking nut 521, so that the effect of balancing the tension is achieved.
Referring to fig. 3-6, when the number of chain rope end modules 5 on the first rope end 1 and the second rope end 2 is the same, one end rope end module 6 is provided on the base 4 of the first rope end 1 and the second rope end 2, respectively.

In particular, the base 4 includes a fixing plate 43 and a bottom plate 44, and a damping gel is filled between the fixing plate 43 and the bottom plate 44, so that running vibration and noise are further reduced. Through holes are respectively formed in the base 4 at positions corresponding to the connecting screw rods 52 and the supporting rods 61, and annular buffer cushions 9 are arranged at the through holes. Since the end of the connecting screw 52 connected with the chain 51 is spaced from the cushion pad 9 by a certain distance, when the chain 51 moves beyond a certain distance around the rotation shaft 42, the end of the connecting screw 52 close to the chain 51 contacts with the cushion pad 9, so that the continuous movement of the chain rope end 53 can be prevented, and the breakage of one traction rope 3 is avoided, and the tension is zero. If the tension of one traction rope 3 is zero and the other traction ropes 3 are connected in series with the broken traction rope 3, the tension of the other traction ropes 3 is also failed, so that the traction rope 3 cannot bear the weight of the elevator car or the counterweight to fall. An included angle is formed between the axial direction of the rotating shaft 42 and the length direction of the base 4, so that the chain rope head assembly 5 is obliquely arranged on the base 4, most of the traction ropes 3 are ensured to be staggered from the guide wheel or the traction wheel rope grooves, the guide wheels or the traction wheel rope grooves are not interfered with each other, and running vibration and noise caused by relative running of the steel wire ropes are effectively prevented.
The automatic adjusting rope head system is arranged, so that the chain rope head components on the first rope head device and the second rope head device are connected in series through the plurality of traction ropes, the other end of the last traction rope is connected with the taper sleeve of the other end rope head component, when the traction force of the traction rope is released, the traction rope grooves of the traction wheel are worn, the rope wheel of each rope reversing rope is changed with the traction force of the rope grooves of the guide wheel and worn, when the tension of one traction rope is changed due to slow change of the length of each rope reversing rope, the chain rope head is pulled, force is transmitted to the chain, the rotation of the rotating shaft can be driven by the chain and the shaft sleeve on the rotating shaft, the length of the adjacent traction rope is changed, the purpose of adjusting the tension of the traction rope is achieved, the tension of each traction rope is consistent, the pressure of the traction rope on the traction wheel is consistent, the traction rope is meshed with the traction wheel more stably, running vibration and noise are reduced, and the comfort of an elevator is improved. In addition, because the pressure of the traction ropes on the traction sheave is consistent, the abrasion of each traction rope and each traction sheave rope groove is also uniform, and the service lives of the traction sheave and the traction ropes are prolonged.
Example 2
Referring to fig. 7 to 9, this embodiment is different from embodiment 1 in that the number of chain rope end components 5 on the first rope end means 1 is N and the number of chain rope end components 5 on the second rope end means 2 is n+1. At this time, two head modules 6 are provided on the base 4 of the first rope hitch 1. The connection of the hoisting rope to the first and second rope end devices is similar to that of example 1: one end of one of the traction ropes 3 is connected with one taper sleeve 7 of one end rope assembly 6 of the first rope head device 1, the other end of the traction rope 3 is connected with one taper sleeve 7 of one chain rope head assembly 5 of the second rope head device 2, the other taper sleeve 7 of the chain rope head assembly 5 is connected with one taper sleeve 7 of one chain rope head assembly 5 of the first rope head device 1 through one traction rope 3, one traction rope 3 of the other taper sleeve 7 of the chain rope head assembly 5 of the first rope head device 1 is connected with one taper sleeve 7 of the other chain rope head assembly 5 of the second rope head device 2, and the other end of the last traction rope 3 is connected with the taper sleeve 7 of the other end rope head assembly 6 of the first rope head device 2 through a plurality of traction ropes 3 in series.
