Description

Building construction hoist

Technical field:

The utility model belongs to the vehicle for construction field, particularly a kind of building hoist.

Background technology:

What at present, generally used the building ground is gantry elevator.But there is following shortcoming in this structure: 1, electric controlled hoist only has a kind of rope speed, and therefore, Applicable scope is limited; 2, do not have safety brake on the electric controlled hoist, have potential safety hazard; 3, being transported to standard knot on the platform from ground, is manually to promote by the pulley on the flat-bed support, therefore wastes time and energy.

The utility model content:

The utility model is exactly at the problems referred to above, and a kind of two kinds of rope speeds that have are provided, and not only safety, but also time saving and energy saving building construction hoist.

The utility model adopts following technical scheme: the utility model comprises standard knot, and the centre of both sides standard knot is a platform, and the serving of electric controlled hoist links to each other with hanging scaffold by the pulley on the platform; But a side of the retarder on the platform is provided with the cylinder with serving of lifting platform, and platform is provided with rollered support, and the opposite side of the retarder on its structural feature platform is provided with bont; The cylinder axle head of electric controlled hoist is provided with wheel hub, and wheel hub is outside equipped with damper brake; Doubly-linked gear with different numbers of teeth is set on the input castellated shaft of the retarder of electric controlled hoist, and the driving lever in the groove between the doubly-linked gear links to each other with the outer crank of retarder.

The beneficial effects of the utility model:

1, can on an electric controlled hoist, realize two kinds of rope speeds:

Because the doubly-linked gear with different numbers of teeth is set on the input castellated shaft of the retarder of the utility model electric controlled hoist, the driving lever in the groove between the doubly-linked gear links to each other with the outer crank of the retarder of electric controlled hoist; The utility model makes the winch that becomes two kinds of rope speeds on the winch, can carry out high-low speed change according to the needs of user's use; Quick shelves can be used when high-rise, shelves at a slow speed can be used during low layer; Not only provide convenience, also saved resource simultaneously to the user;

2, safety:

Because the axle head of the cylinder of the utility model electric controlled hoist is provided with wheel hub, wheel hub is outside equipped with damper brake; When having an accident, damper brake can in time be realized automatic train stop, avoids the generation of accident;

3, time saving and energy saving:

Because the opposite side of the retarder on the platform is provided with bont, just can remove manually promoting ground standard knot by the support top sheave from, and is therefore not only time saving and energy saving, and improved work efficiency.

The specific embodiment:

The utility model comprises standard knot 4, and the centre of both sides standard knot 4 is a platform 12, and the serving 2 of electric controlled hoist 1 links to each other with hanging scaffold 3 by the pulley 5 on the platform 12; But a side of the retarder 7 on the platform 12 is provided with the cylinder with serving 9 10 of lifting platform 12, and platform 12 is provided with the support 8 with pulley 11, and the opposite side of the retarder 7 on the platform 12 is provided with bont 6; Cylinder 31 axle heads of electric controlled hoist 1 are provided with wheel hub 34, and wheel hub 34 is outside equipped with damper brake 35; Doubly-linked gear 38 with different numbers of teeth is set on the input castellated shaft 37 of the retarder 30 of electric controlled hoist 1, and the driving lever 40 in the groove 39 between the doubly-linked gear 38 links to each other with retarder 30 outer cranks 41.

Bont 6 comprises that the bearing 28 of axis 18 is outside equipped with the cylinder 16 with serving 17, axis 18 ends are bracing strut 13, be conjoint disk 14 between bracing strut 13 and the cylinder 16, have in the conjoint disk 14 and axle key 19, positioning groove 20 corresponding through holes, knock hole 23, have spring 22, ball 21 in the knock hole 23, the fulcrum 24 on driving lever 15 coaxial stents 13 in the outer rim groove 25 of conjoint disk 14 links to each other; One side of conjoint disk 14 is provided with cylinder 16 side grooves 27 corresponding latches 26.

Retarder 30 on the base 29 of electric controlled hoist 1 links to each other with the cylinder 31 with serving 2, motor 33 with band-type brake 32 respectively; The fulcrum 44 of damper brake 35 is fixed on the support 45 of base 29, and the front end of the joystick 46 on the fulcrum 44 has the fulcrum 43 of wheel hub 34 brake rubber blocks 42.

If when extracting standard knot 4 from ground, the opposite side that starts the retarder 7 on the platform 12 is provided with bont 6, just can extract standard knot 4 by the pulley on platform 12 supports 8 11.

If change rope speed, crank 41 is turned in the detent 47; Driving lever 40 is action thereupon just, makes 38 actions of doubly-linked gear by detent 47, is meshed with different gears on the next stage axle 36 with the different teeth of doubly-linked gear 38, has just realized two kinds of rope speeds.

If when something unexpected happened maybe need stop, can press down joystick 46; Then joystick 46 rotates around the fulcrum 44 of support 45, and just joystick 46 rotations thereupon of two fulcrums 43 of the brake rubber block 42 outside the wheel hub 34 just pack tightly wheel hub 34 with brake rubber block 42, just play good brake action.
