Abstract
The utility model discloses a novel brake device for a traction machine. The brake device comprises a traction sheave, a brake device, an electric motor and a frame, wherein the traction sheave, the brake device, the electric motor are arranged on the frame respectively. The height of groove walls at two sides of a groove of the traction sheave is at least not less than the width of the slot. The brake device is arranged at the outer side of the traction sheave. The novel brake device for the traction machine modifies and simplifies the structure of the traction machine, integrates various parts as a whole, reduces size, lightens self-weight of the traction machine, lowers production cost, is simple and convenient in transportation and installation, and also effectively reduces the possibility that a steel wire rope may release from or jump out of the groove of the traction sheave while faults that an elevator car bumps to the top or the bottom occur.
Description
Technical field
The utility model relates to a kind of novel towing machine brake equipment, belongs 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.
The utility model content
The technical matters that the utility model 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 utility model 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 utility model; 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 the further understanding to the utility model, and constitutes the part of specification sheets, is used to explain the utility model with the embodiment of the utility model, does not constitute the restriction to the utility model.In the accompanying drawings:
Fig. 1 is the front elevation of a kind of novel towing machine brake equipment of the utility model;
Fig. 2 is the lateral plan of a kind of novel towing machine brake equipment of the utility model;
Fig. 3 is the partial enlarged drawing of a kind of novel towing machine brake equipment of the utility model.
The specific embodiment
Describe below in conjunction with the preferred embodiment of accompanying drawing, should be appreciated that preferred embodiment described herein only is used for explanation and explains the utility model, and be not used in qualification the utility model the utility model.
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 utility model; 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 embodiment of the utility model; Be not limited to the utility model; Although the utility model 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 the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
