Description

Slag external grabbing type suspender

Technical field

The utility model relates to the preceding slag treatment facility of a kind of State of Blast Furnace, slag external grabbing type suspender before particularly a kind of State of Blast Furnace.

Background technology

In medium and small blast furnace, because the low slag flow of slag temperature is less, slag needs every stove cleaning in the slag runner, generally adopts the scissors grapple to come the handling slag.Fig. 1 is the scheme drawing of scissors grapple, and the scissors grapple is made of two gripping

arms

1,2, provide a central pin shaft 3 to connect near the midway location of gripping

arm

1,2, connects steel cable 4 in the upper end of gripping

arm

1,2, hangs steel cable 4 and comes the handling slag by grabbing.There is following defective in this scissors grapple: the width of dehiscing of (1) gripping arm is less than normal.Because central pin shaft is at the medium position of gripping arm, the width of dehiscing is less than normal, causes the slag of bulk need break into fritter into pieces and just can pick up, and increases work capacity; (2) grip is big inadequately.Because the structure of scissors grapple causes the size of its grip mainly to be decided by the weight of grapple and slag, grapple weight is constant, and the inner structure of slag is loose, and density is less, causes grip less than normal, is prone to obscission in grabbing the process of hanging; (3) structure of scissors grapple causes its two gripping arms not on same plane, has friction stress, very easily causes the clinker fracture in grabbing the process of hanging, and brings potential safety hazard.

Summary of the invention

For addressing the above problem, the utility model provides a kind of slag external grabbing type suspender, moves to the gripping arm top by the rotating fulcrum with gripping arm, guarantees that suspender has the bigger width of dehiscing, and guaranteeing has enough big grip, guarantees to grab that clinker is unlikely to split away off when hanging.

For achieving the above object, slag of the present utility model external grabbing type suspender, comprise left gripping arm 11, right gripping arm 12, right annulus 13, left side annulus 14, last annulus 15, the U type unloads shell 16 and steel rope 18, described right annulus 13 is fixed on the bottom of right gripping arm 12, described left annulus 14 is fixed on the top of left gripping arm 11, described upward annulus 15 is fixed on the U type and unloads on the shell 16, it is fixing that the upper end of described left gripping arm 11 and U type unload shell 16 welding, the upper end of described right gripping arm 12 is unloaded shell 16 by fixed pin shaft 17 and U type and is connected, described right gripping arm 12 can be rotated around fixed pin shaft 17, also is respectively equipped with left hook pin 111 and right hook pin 121 in the lower end of left gripping arm 11 and right gripping arm 12, and described steel rope 18 passes right annulus 13 successively, left side annulus 14, last annulus 15.

Described left gripping arm 11 and right gripping arm 12 adopt six-edged steel to make.

The position of described right annulus 13 is at 1/3 brachium place of right gripping arm 12 bottoms, and the position of left annulus 14 is at the 1/3 brachium place on left gripping arm 11 tops.

Slag of the present utility model is that fixed pin shaft 17 moves to the gripping arm top with the external grabbing type suspender with the rotating fulcrum of gripping arm, guarantees that suspender has the bigger width of dehiscing.Under equal gripping arm length condition, the width of dehiscing of this suspender is the twice of scissors grapple, can pick up the more slag of bulk.The mode that adopts steel rope to combine with annulus fixes on the point of application of grip in the gripping arm, and rationally determines its position, guarantees enough grips, and the grip size is along with the weight increase of clinker and strengthen.

Slag of the present utility model is light and handy, convenient, durable with the external grabbing type suspender, greatly reduces operative employee's labour intensity, increases work efficiency; Guarantee enough big grip, guaranteed to grab that clinker is unlikely to split away off when hanging, improved safety factor; Eliminated the adverse effect of friction stress, reduced and grabbed the probability that the clinker fracture takes place in the process of hanging.

Fig. 1 is the scheme drawing of scissors grapple;

Fig. 2 is a slag of the present utility model external grabbing type suspender scheme drawing.

The specific embodiment

Fig. 2 is a slag usefulness external grabbing type suspender scheme drawing of the present utility model, and as shown in the figure, slag of the present utility model comprises left gripping arm 11 with the external grabbing type suspender, right gripping arm 12, and right annulus 13, left annulus 14, last annulus 15, the U type unloads shell 16 and steel rope 18.Described right annulus 13 is fixed on the bottom of right gripping arm 12, described left annulus 14 is fixed on the top of left gripping arm 11, described upward annulus 15 is fixed on the U type and unloads on the shell 16, it is fixing that the upper end of described left gripping arm 11 and U type unload shell 16 welding, the upper end of described right gripping arm 12 is unloaded shell 16 by fixed pin shaft 17 and U type and is connected, described right gripping arm 12 can be rotated around fixed pin shaft 17, and described steel rope 18 passes right annulus 13, left annulus 14 successively, goes up annulus 15.

Also be respectively equipped with left hook pin 111 and right hook pin 121 in the lower end of left gripping arm 11 and right gripping

arm

12,11 one-tenth 75 degree of left hook pin 111 and left gripping arm, 12 one-tenth 75 degree of right hook pin 121 and right gripping arm.

Left side gripping arm 11 and right gripping arm 12 adopt six-edged steel to make.Gripping arm is adopted six-edged steel and is not adopted circular steel, mainly considers the intensity height of six-edged steel, and bending resistance is strong.

In use, earlier clinker is hooked in left gripping arm 11 and right gripping arm 12, hook with driving hooks steel rope 18 pull-ups then, after steel rope 18 is stressed, with left and right

sides gripping arm

11,12 tensions, catch clinker by left annulus 14, right annulus 13, hang and deliver to the slag bucket, unclamp steel rope, gripping arm is unclamped, promptly finish handling clinker task.

Right gripping arm 12 grip point of application positions are exactly the position of right annulus 13.For guaranteeing that left and right

sides gripping arm

11,12 has enough grips, right annulus 13 needs as far as possible near right gripping arm 12 lower ends, but too by under can run into clinker, influence is grabbed and is hung, determine repeatedly by practice, right annulus 13 rational positions are preferably in 1/3 brachium place of right gripping arm 12 bottoms, and left annulus 14 is preferably in the 1/3 brachium place on left gripping arm 11 tops.

Grip is distributed on the annulus of two gripping arms, the grip size is main relevant with the open angle of gripping arm with clinker weight, do not need to rely on the weight that strengthens suspender to increase grip, therefore, the weight of this suspender reduces greatly, becomes more light and handy, has reduced working strength of workers, only need a workman just passable during use, improved work efficiency.

Adopt the U type to unload shell 16 and left and right

sides gripping arm

11,12 is connected, guarantee left gripping arm 11 and right gripping arm 12 places at grade, eliminate the phenomenon that friction stress causes the clinker fracture with fixed pin shaft 17.
