Abstract

A device for controlling and regulating steering of hook of crane, which is characterized in that: an upper bed plate and a lower bed plate are respectively welded in a hook case body; a reduction box and a hook bracket are also arranged in the hook case body. The hook bracket driven by the reduction box can rotate slowly along the horizontal direction so as to drive the hook to rotate smoothly, and thus the place of the objects which are being hung can be controlled so as to be benefit for loading and stacking. The utility model is applicable for the steering of hangers such as the gantry cranes of port, tire cranes and other hangers which are used for loading or stacking.

Description

A kind of control aligned the device that crane hook turns to

The utility model relates to a kind of device that the levelling crane hook turns to of controlling, and in the time of especially effectively controlling levelling hoisting crane lifting operation, the rotation that suspension hook produces makes suspended object spare determine the position easily, is convenient to the high operation of lifting heap.

The hoisting crane that harbour handling operation is at present generally used is when lifting operation, because during the lifting of the steel rope of connecting shackle, produce steel rope and turn round the influence of sth. made by twisting and natural wind, wind direction, suspension hook rotates easily, and suspension hook and suspended object spare and then rotate so, when particularly the large-sized object of same size lifting heap is high, be difficult for aligned position, at this moment must or bind object and implement push-and-pull, rotation, aligned position with manual method with rope, can finish the high operation of lifting heap, labour intensity is big.When if freight container is piled height to 4 layers, highly existing about ten meters, loading and unloading operation personnel stand in eminence, should pay close attention to the lockhole position of freight container counter, dodge the collision of the freight container counter of rotation again, exist unsafe hidden danger.

In order to overcome the rotation naturally of present hoisting crane suspension hook that lifting operation causes, must be with the deficiency of manually coming push-and-pull, levelling position when causing container hanging to pile high operation, the utility model provide a kind of with reductor slow down significantly, transmission.By speed reducer output shaft link to each other with suspension hook frame spindle nose, transmission, control the slow rotation of levelling suspension hook frame, thereby order about suspension hook and suspended object spare rotates, implement the high operation of lifting heap.

The scheme that its technical matters that solves the utility model adopts is: ACTIVE CONTROL, levelling crane hook turn to, and are made up of suspension hook casing, reductor, suspension hook frame, bearing, upper base plate, following seat board, suspension hook axle, suspension hook etc.Reductor is fixed by bolts on the interior upper base plate of suspension hook casing.Double reduction unit is adopted in the running of energized drive speed reducer, and through slowing down significantly, the rotating speed of speed reducer output shaft only is that per minute one changes.Spindle nose is a flange-shape, and being connected spindle nose on the suspension hook frame is groove shape, can conveniently connect, transmission.The termination of suspension hook frame is an Acme thread, on the following seat board bearing is housed, and the axle head of suspension hook frame is passed the following seat board that bearing is housed, and refills surface bearing, packing ring, and with trapezoidal nut the suspension hook frame is fixed on down on the seat board.Packing ring and spring cotter are loaded onto in the trapezoidal nut outer end, prevent from that trapezoidal nut from circling round to unclamp.With electric welding with upper base plate and following seat board respectively with suspension hook casing firm welding.The suspension hook frame can realize that 360 ° of horizontal direction rotate freely.Penetrated by the suspension hook axle in the loser of suspension hook, and be fixed on the suspension hook frame, suspension hook can swing back and forth in vertical direction.If during horizontal installations of reductor, can load onto cone gear at speed reducer output shaft, spindle nose is loaded onto cone gear on the suspension hook frame, and engaged transmission drives the rotation of suspension hook frame.Reductor can freely rotate along backward, operates reductor like this and can order about the rotation of suspension hook frame easily, and the rotation of controlling, aligning suspended object spare lifts the high operation of heap.

The beneficial effects of the utility model are to be linked to each other with suspension hook frame upper groove spindle nose by mouth flange spindle nose by reductor to fetch the slow rotation of control, levelling suspension hook frame, and steady, easy to operate, good reliability turn round.

Accompanying drawing is a kind of apparatus structure scheme drawing that the levelling crane hook turns to of controlling.Now the utility model is described in further detail in conjunction with the accompanying drawings.Suspension hook casing (1), reductor (2), upper base plate (3), flange output shaft head (4), groove spindle nose (5), spring cotter (6), packing ring (7), trapezoidal nut (8), surface bearing (9), following seat board (10), bearing (11), suspension hook frame (12), suspension hook axle (13), suspension hook (14) among the figure.

Embodiment of the present utility model: with electric welding upper base plate (3) and following seat board (10) are welded in suspension hook casing (1) respectively between the boxboard of suspension hook casing (1), are used to install reductor (2) and suspension hook frame (12).Bearing (11) is equipped with on following seat board (10) top, and the plane of bearing (11) is a little less than the last plane of following seat board (10).The top of suspension hook frame (12) is groove spindle nose (5), and secondary segment is an Acme thread.The shaft part of suspension hook frame (12) passes down seat board (10), bearing (11), refills surface bearing (9).Use trapezoidal nut (8) that suspension hook frame (12) is fixed in seat board (10) down then.Align surface bearing (9) minor increment of seat board (10) extremely down, be advisable freely rotating.Trapezoidal nut adds upper gasket (7) and spring cotter (6), unclamps to prevent that trapezoidal nut (8) from circling round.Reductor (2) uses bolt on upper base plate (3), but the axle center of the output flange spindle nose of necessary assurance reductor (2) is consistent with the axle center of suspension hook frame (12) groove spindle nose, is connected appropriate with the groove spindle nose flange spindle nose in the permissible error of reductor (2).When motor-driven reductor (2), through slowing down significantly, reductor output flange-shape spindle nose speed only is that per minute one changes like this.The flange oblique crank Z of rotation drives suspension hook frame (12) slowly pulsation-free rotation in the horizontal direction, drives suspension hook (14) rotation by suspension hook axle (13) again.The so just rotation that can control, align suspended object spare lifts the high operation of heap.

Claims

1. control the device that the levelling crane hook turns to for one kind, form, it is characterized in that the speed reducer output shaft head in the suspension hook casing links to each other with the spindle nose of suspension hook frame by suspension hook casing, upper base plate, following seat board, reductor, bearing, suspension hook frame, nut, suspension hook etc.

2. a kind of device that the levelling crane hook turns to of controlling according to claim 1 is characterized in that the output shaft center of reductor is consistent with the axle center of suspension hook frame, and the spindle nose of speed reducer output shaft is flange shape, and the spindle nose of suspension hook frame is the groove shape, directly links to each other.

3. a kind of device of turning to of levelling crane hook of controlling according to claim 1, when it is characterized in that horizontal installations of reductor, output shaft is loaded onto cone gear, loads onto cone gear on the spindle nose of suspension hook frame, and the transmission that is meshing with each other drives the rotation of suspension hook frame.
