Abstract
The utility model discloses a hoisting mechanism of a single hoisting point foundry crane, which relates to a foundry crane, solves the problem that a hoisting mechanism of the traditional single hoisting point foundry crane has high manufacturing cost and also meets the requirement of latest national safety standard. The hoisting mechanism is characterized in that two ends of a roller 1 are respectively connected with a left speed reducer 2-1 and a right speed reducer 2-2 through a roller coupling 3; the left speed reducer 2-1 and the right speed reducer 2-2 are respectively driven by a left motor 5-1 and a right motor 5-2; a roller coupling between the roller 1 and the left speed reducer 2-2 is a spherical hinge roller coupling 3-1; and a roller coupling between the roller 1 and the right speed reducer 2-2 is a spherical hinge roller coupling 3-2.
Description
Technical field
The utility model relates to ladle carne, particularly a kind of lifting mechanism of ladle carne.
Background technology
The lifting mechanism of single in the past suspension centre ladle carne adopts structure as shown in Figure 1, is made up of reel 1, retarder 2, drum coupling 3, drg 4, motor 5, drum shaft bearing 7, top sheave group 8.Adopt single motor, single retarder, single drum form, drive reel work by retarder by motor.Be characterized in simple in structure, cost is low.But slow-speed shaft has only power resources, as long as one zero, parts et out of order are arranged on the whole messenger chain, all can't work on, promptly can not finish a working cycle in the state of accident, if retarder generation breaking axis, can make lifting mechanism out of control, cause serious accident, so poor stability.
The up-to-date safety rate requirement of country, the hoisting crane of every handling guiding principle water bag must adopt between the slow-speed shaft rigidly connected lifting mechanism, can finish a working cycle in the state of accident.As shown in Figure 2, promptly be the lifting mechanism of a kind of double-motor, dual reducer, be rigidly connected between the slow-speed shaft, can finish the lifting mechanism of a working cycle in the state of accident.Form by reel 1, retarder 2, drum coupling 3, drg 4, motor 5, coupler 6, drum shaft bearing 7, top sheave group 8, adopt double-motor, dual reducer, two drum coupling, two reel, two drum shaft bearing, connect by coupler between the drum shaft bearing.This structure can satisfy up-to-date safety rate requirement, but complex structure, cost is higher.Not only want many two drum shaft bearings and a big coupler, and because the drum shaft bearing and between coupler take up room, make reel effectively use length to dwindle, must strengthen drum diameter, strengthen retarder, the suspender that matches simultaneously is also complicated, strengthened manufacturing cost.
Summary of the invention
The purpose of this utility model is exactly at the deficiencies in the prior art, and a kind of lifting mechanism of single suspension centre ladle carne is provided, and solves the existing high problem of single suspension centre ladle carne lifting mechanism manufacturing cost, can satisfy the requirement of national up-to-date safety rate simultaneously.
The technical solution of the utility model is:
A kind of lifting mechanism of single suspension centre ladle carne, by the motor-driven retarder, retarder is connected with reel by drum coupling, drg is arranged on the retarder side, reel is connected with the top sheave group with steel rope, it is characterized in that: the two ends of described reel are connected with right retarder with left retarder by described drum coupling respectively, described left retarder and right retarder are respectively by left motor and right motor-driven, drum coupling between described reel and the described left retarder is a kind of ball pivot drum coupling, and the drum coupling between described reel and the described right retarder is a kind of spherical roller drum coupling.
The utility model compared with prior art, owing to adopt double-motor, dual reducer, two drum coupling, single drum structure, motor drives reel work by retarder, drum coupling, it is the ball pivot drum coupling that respectively there are a drum coupling and one in the two ends of reel, one is the spherical roller drum coupling, so mechanism's slow-speed shaft is to be rigidly connected.During normal operation, drive reel work by two retarders of two driven by motor, when on one side motor or retarder or drg break down, can finish a working cycle by the driven by motor retarder of another side, this moment each zero, parts only need satisfy requirement of strength and get final product.Lifting mechanism than single suspension centre ladle carne in the past is safer.Owing to adopt the ball pivot drum coupling can retrain the longitudinal travel of roll device, adopt the spherical roller drum coupling can compensate the longitudinal travel of roll device, therefore more reasonable than the lifting mechanism of single suspension centre ladle carne in the past.
Description of drawings
Fig. 1 is the scheme drawing of a kind of single suspension centre ladle carne lifting mechanism of prior art;
Fig. 2 is the scheme drawing of another single suspension centre ladle carne lifting mechanism of prior art;
Fig. 3 is a structural representation of the present invention.
The utility model is further described by preferred embodiment below in conjunction with accompanying drawing.
The specific embodiment
As shown in Figure 3, a kind of lifting mechanism of single suspension centre ladle carne, drive retarder 2 by motor 5, retarder 2 is connected with reel 1 by drum coupling 3, drg 4 is arranged on retarder 2 sides, reel 1 usefulness steel rope is connected with top sheave group 8, the two ends of described reel 1 are connected with right retarder 2-2 with left retarder 2-1 by described drum coupling 3 respectively, described left retarder 2-1 and right retarder 2-2 are driven by left motor 5-1 and right motor 5-2 respectively, drum coupling between described reel 1 and the described left retarder 2-1 is a kind of ball pivot drum coupling 3-1, and the drum coupling between described reel 1 and the described right retarder 2-2 is a kind of spherical roller drum coupling 3-2.
