Description
Technical Field
The invention belongs to the technical field of elevator accessories, and particularly relates to a rope head combination device of an elevator car traction rope, which is used for fixing the rope head of the elevator car traction rope.
Background
The above-mentioned traction rope for the elevator car is driven by the traction sheave of the traction machine in a friction manner under the operation of the traction machine, and both ends of the traction rope are respectively fixed with a carrier at the top of a hoistway (a passage through which the elevator car moves up and down) (the carrier at the top is generally called a "hoistway supporting plate" or a "rope end plate", hereinafter the same), while the middle part of the traction rope is wound around the traction sheave of the traction machine for the elevator, the car sheave provided at the top of the elevator car, and the balancing weight guide pulley wound around the balancing weight.
Technical information about elevator car traction rope end assemblies can be found in the published chinese patent literature such as grant publication numbers CN201268536Y (belt traction rope end assembly), CN202464993U (rope end assembly) and CN203593492U (an elevator rope end compression spring stabilizing device), etc. Furthermore, it is also known in the art of proximity that, for example, the grant publication number CN203743308U recommends "rope hitch in hoisting equipment".
The general disadvantages of the rope end assembly provided by the above-cited patent solutions are not limited to being complemented by the "rope end assembly" recommended by the invention patent application publication number CN104370181a, and reference is specifically made to paragraphs 0004, 0018 and 0022 to 0028 of the specification of CN104370181 a. However, this CN104370181a still suffers from the following drawbacks: first, since the rope end of the traction rope needs to be fixed by rolling with the rope end loop bar, for example, it is pointed out in paragraph 0028: "the rope end of the haulage rope is inserted into the lower end of the rope end loop bar and is pressed by the crimping pliers, so that the lower end of the rope end loop bar is deformed and is reliably extruded with the rope end, the crimping pliers such as the wire hydraulic crimping pliers in the electric power line construction equipment or the like, thus the fixing operation of the rope end is very troublesome and the installation efficiency is low and the installation difficulty is high because of the crimping pliers as peripheral equipment; secondly, because the fixedly connected area of the rope end and the rope end loop bar is limited to the area with the extrusion groove, and the materials of the traction rope and the rope end loop bar are different, and the coefficients of thermal expansion and cold contraction are different, the rope end is loosened and even breaks loose from the rope end loop bar, and the current solution is to replace in time in periodic or unscheduled inspection and protection.
The "elevator car haulage rope end combination device" recommended by CN204778175U makes up the above-mentioned shortcomings and can objectively honor the advantages of three aspects summarized in the technical effect column of the specification thereof. However, in addition to the rope hitch, the tapered clamping sleeve (referred to as "tapered clamping sleeve") and the lock nut sleeve, the CN204778175U further has a vibration damping support mechanism connected to the upper end of the rope hitch and supported on the hoistway ceiling at the top of the hoistway in use, the vibration damping support mechanism includes a screw and a lock nut mounted on the screw as a carrier, and the following technical problems are caused by the fact that: firstly, because the structure of the vibration reduction supporting mechanism is out of rationality, the rope head combination device of the whole elevator car traction rope occupies large space, and thus, the trouble is brought to occasions with limited installation space; secondly, because the vibration reduction supporting mechanism has a large number of parts, the structure is complex, the manufacturing and the assembly are not convenient, the economy is not easy to be reflected, and the resource waste is also caused; thirdly, the screw rod of the structural system of the vibration reduction supporting mechanism is connected with the rope head loop bar only by a locking pin, so that the locking pin is stressed greatly, and accidents can be caused once the locking pin breaks or the like.
