Abstract
The invention provides a novel traction machine brake device, which comprises a traction sheave, a brake device, a motor and a rack, wherein the traction sheave, the brake device and the motor are arranged on the rack respectively; the heights of groove walls on two sides of a rope groove of the traction sheave are not smaller than the width of the groove; and the brake device is arranged outside the traction sheave. According to the novel traction machine brake device, the structure of a traction machine is modified and simplified, and all parts are integrated into a whole, so that the size is reduced, the self weight of the traction machine is reduced, the production cost is decreased, the brake device is easy and convenient to transport and mount, and the probability that a steel wire rope is separated or jumps from the rope groove of the traction sheave when an elevator cage crushes to the top or collapses to the bottom is effectively reduced.
Description
Technical field
The present invention relates to a kind of novel towing machine brake equipment, belong to the brake equipment field.
Background technology
Present known various elevator traction machine braking devices; Its design is absolute construction; No matter be various forms drgs such as external drum-type, built-in drum-type or shoe type, piece formula, ventilated disc, friction-disc; For parts such as the drg of towing machine, traction sheave, ward off rope device, car protection device for over-speed ascending no direct correlation such as drg and traction sheave, ward off rope device, protection device for over-speed ascending are set independently.
These products are because isolation of components such as traction machine brakes, traction sheave, ward off rope device, car up-running over-speed protection, have that productive costs is high, craft precision is strict, oad is big, braking inertia greatly, shortcomings such as transportation and difficult installation.When especially present ward off rope device rushes to summit, squats emergency situation such as the end, safety tongs action at elevator, be difficult to prevent that traction steel-cable breaks away from the traction sheave grooving, bring a lot of difficulties can for the maintenance work in later stage in case take off groove.
Summary of the invention
The technical matters that the present invention will solve is to overcome existing defective, and a kind of novel towing machine brake equipment is provided, and has characteristics such as safe and reliable, simple in structure, low-cost, that installation and maintenance convenient, fault rate is low.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
A kind of novel towing machine brake equipment comprises traction sheave, brake equipment, electrical motor and frame, and traction sheave, brake equipment and electrical motor are installed on the frame respectively; The grooving both sides cell wall height of traction sheave is not less than the groove width width at least; Brake equipment is arranged on the traction sheave outside.
Further, traction sheave is that whole car becomes the big 5mm of cell wall aspect ratio groove width width.
Brake equipment is drg and drg bonded assembly brake bush, and brake bush is two, and the width of brake bush is identical with the traction sheave width.
Principle: grooving cell wall height is not less than the groove width width, and steel rope is completely contained in grooving inside, adds the brake equipment in the traction sheave outside, has prevented that effectively rope breaks away from groove, has therefore saved the ward off rope device that prevents the steel rope job-hopping or take off groove; When brake bush is worked, act directly on the outer rim of traction sheave, produce lock torque through the friction force between brake bush and the traction sheave outer surface wheel rim, realize braking function, therefore saved brake wheel; Drg can directly act on and traction sheave in the traction sheave outside, need not the independent installation overspeed protection device.
A kind of novel towing machine brake equipment of the present invention; Revise and simplify the structure of towing machine; Each parts is integrated one; Minification, alleviate towing machine conduct oneself with dignity, reduce production costs, transport and install simple and convenient, and effectively reduce lift car rush to summit or squat the end during fault steel rope take off the possibility of groove or job-hopping in the traction sheave grooving.
Description of drawings
Accompanying drawing is used to provide further understanding of the present invention, and constitutes the part of specification sheets, is used to explain the present invention with embodiments of the invention, is not construed as limiting the invention.In the accompanying drawings:
Fig. 1 is the front elevation of a kind of novel towing machine brake equipment of the present invention;
Fig. 2 is the lateral plan of a kind of novel towing machine brake equipment of the present invention;
Fig. 3 is the partial enlarged drawing of a kind of novel towing machine brake equipment of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for explanation and explains the present invention, and be not used in qualification the present invention.
Like Fig. 1,2, shown in 3, a kind of novel towing machine brake equipment comprises traction sheave 1, brake equipment, electrical motor 2 and frame 3, and traction sheave, brake equipment and electrical motor are installed on the frame respectively; The grooving both sides cell wall height of traction sheave is not less than the groove width width at least; Brake equipment is arranged on the traction sheave outside.
Further, traction sheave is that whole car becomes the big 5mm of cell wall aspect ratio groove width width.
Brake equipment is drg 4 and drg bonded assembly brake bush 5, and brake bush is two, and the width of brake bush is identical with the traction sheave width.
The width of brake bush is identical with the traction sheave width; According to national relevant regulations, the gap between brake bush and the baffle plate is no more than 0.7mm, has accomplished to cover fully grooving; Grooving cell wall height is not less than the groove width width in addition; Steel rope is completely contained in grooving inside, has prevented that effectively rope breaks away from groove, therefore saved the ward off rope device that prevents the steel rope job-hopping or take off groove; When brake bush is worked, act directly on the outer rim of traction sheave, produce lock torque through the friction force between brake bush and the traction sheave outer surface wheel rim, realize braking function, therefore saved brake wheel; Drg can directly act on and traction sheave in the traction sheave outside, need not the independent installation overspeed protection device.
A kind of novel towing machine brake equipment of the present invention; Revise and simplify the structure of towing machine; Each parts is integrated one; Minification, alleviate towing machine conduct oneself with dignity, reduce production costs, transport and install simple and convenient, and effectively reduce lift car rush to summit or squat the end during fault steel rope take off the possibility of groove or job-hopping in the traction sheave grooving.
What should explain at last is: the above is merely the preferred embodiments of the present invention; Be not limited to the present invention; Although the present invention has been carried out detailed explanation with reference to previous embodiment; For a person skilled in the art, it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement.All within spirit of the present invention and principle, any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
