Abstract
The invention relates to the technical field of components of elevators, in particular to a tensioning wheel assembly of a speed limiter. The tensioning wheel assembly comprises a fixing seat, a rope wheel connecting seat and a rope wheel. The rope wheel connecting seat is movably connected with the fixing seat, the rope wheel is arranged on the rope wheel connecting seat, a safety switch is arranged at the end, which is close to the rope wheel connecting seat, of the fixing seat, the rope wheel connecting seat moves around the fixing seat by the aid of a movable nut, and a switch knocking plate is sleeved on the movable nut and corresponds to the safety switch. The tensioning wheel assembly has the advantages that the safety switch and the switch knocking plate can act cooperatively without increasing the weight of the tensioning wheel assembly, and both the reliability and the stability of the tensioning wheel assembly are improved; the tensioning wheel assembly is reasonable in design, simple in structure and convenient to install and detach, and the cost is lowered.
Description
Technical field
The present invention relates to the elevator parts technical field, be specifically related to the governor tension pulley assembly.
Background technology
When the elevator downstream rate surpasses governor tripping speed, the velocity limiter action, a kind of method can be clamped steel rope with rope clamping block, and steel rope is held with the descending control stalk of car and is made the safety tongs action; Another kind method can be blocked rope sheave and utilize the gravitation pulling of dragging of steel rope to make the safety tongs action with the descending control stalk of car.In the prior art, for guaranteeing safety tongs energy action message, generally by the realization of gaining in weight, this not only increases cost, and installing/dismounting is also inconvenient, brings simultaneously the problems such as rope stretch, speed limiter system strength analysis.
Summary of the invention
The purpose of this invention is to provide a kind of reasonable in design, simple in structure, easy accessibility, need not increase the governor tension pulley assembly of own wt.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: the governor tension pulley assembly, the rope sheave Connection Block that comprises permanent seat, is flexibly connected with described permanent seat and be arranged on rope sheave on the described rope sheave Connection Block, described permanent seat is provided with safety switch near an end of rope sheave Connection Block, described rope sheave Connection Block is movable around described permanent seat by traveling nut, socket switch re-packs on the described traveling nut, the setting corresponding to safety switch that re-pack of described switch.
Further, a side of described rope sheave is provided with dust boot, and described dust boot is provided with dustproof brush.
The present invention has following beneficial effect: governor tension pulley assembly of the present invention, the rope sheave Connection Block that comprises permanent seat, is flexibly connected with permanent seat and be arranged on rope sheave on the rope sheave Connection Block, and be provided with safety switch near an end of rope sheave Connection Block and switch re-packs at permanent seat; The present invention need not to increase own wt, and can make safety switch and the switch interoperation that re-packs, and reliability and stability all improve.In addition, the present invention have reasonable in design, simple in structure, reduce cost, easy installation and removal.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing invention is further described in detail.
As shown in Figure 1, the governor tension pulley assembly, the rope sheave Connection Block 2 that comprises permanent seat 1, is flexibly connected with described permanent seat 1 and be arranged on rope sheave 3 on the described rope sheave Connection Block 2, wherein, rope sheave 3 and rope sheave Connection Block 2 are connected by screw fastening, described permanent seat 1 is provided with safety switch 4 near an end of rope sheave Connection Block 2, described rope sheave Connection Block 2 passes through traveling nut 5 around described permanent seat 1 activity, socket switch re-packs 6 on the described traveling nut 5, described switch re-pack 6 with safety switch 4 corresponding settings; In the present embodiment, when the elevator downstream rate surpasses governor tripping speed, utilize steel rope on the rope sheave 3 drag gravitation hold with the descending control stalk of car make switch re-pack 6 with safety switch 4 interoperations, and reliability and stability all improve.
One side of described rope sheave 3 is provided with dust boot 7, and described dust boot 7 is provided with dustproof brush 8, and in the present embodiment, the effect of dust boot and dustproof brush is to avoid the intrusion of dust on the steel rope, impurity, guarantees that tension wheel is reliable stable.
Explanation is at last, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, other modifications that those of ordinary skills make technical scheme of the present invention or be equal to replacement, only otherwise break away from the spirit and scope of technical solution of the present invention, all should be encompassed in the middle of the claim scope of the present invention.
