Abstract
The utility model relates to a small type lifting hoist which is suitable for being operated in countryside or small building sites. The utility model is characterized in that lazy arms are supported above towers; an upper and a lower towers are provided with devices for adjusting height; the bottom of each tower is provided with a machine frame, a supporting plate, a slewing mechanism, a walking wheel, and a supporting frame. A diesel engine is arranged on the machine frame, and the diesel engine drive rolling wheels, a connecting rod, etc. to hoist through a gear box. The utility model has the advantages of simple structure and lower motive power, and the lazy arms and the machine frame can move up and down or rotate.
Description
The utility model relates to a kind of lifting crane, is power with the diesel engine particularly, draws with walker tractor, is suitable for the lifting crane of rural area or little site operation.
Known lifting crane has hoisting crane that automobile is used as power and the fixed tower posture hoisting crane that is used as power with electrical motor, the crane volume of these types is big, complex structure, cost height, and, unregulated power supply narrow or electric power supply inconvenience in many rural areas and samll cities and towns place, do not use these large cranes, so winch and pulley hoisting heavy are used in present many samll cities and towns and rural area when building not too high building, what have also draws with manually hanging with rope, these install, and not only efficient is low, and use is absolutely unsafe.
The purpose of this utility model provides a kind of simple in structure, cost is low, convenience is mobile, safe and reliable small-sized lifting crane that is suitable for that the little place of rural area or samll cities and towns uses.
The utility model is achieved in that small-sized lifting crane comprises pylon, arm, steel rope, suspension hook, actuating unit, be characterized in that pylon is divided into pylon and following pylon, the top of last pylon has fulcrum to support arm, pylon has regulating mechanism adjustment height, frame, supporting plate are equipped with in the pylon bottom, swing type mechanism, road wheel and pillar, swing type mechanism is contained in the frame below, swing type mechanism has joystick and steering handwheel, can make pylon do 0-360 ℃ of rotation, plate supporting frame can arbitrarily move whole crane on walker tractor or small four-wheel tractor farm vehicle.One of frame is equipped with diesel motor, change speed gear box is equipped with on the next door of diesel engine, and change speed gear box is equipped with roller and connecting rod, Wound steel rope on the roller, link on the pulley and suspension hook of arm, connecting rod is linked on the height adjustment mechanism of pylon, is used to regulate the height of pylon, and luffing mechanism also is housed on the frame, be connected with arm, be used to regulate the angle [alpha] between arm and the pylon, arm is made removable several sections as required, to adapt to differing heights and angle operation.
The working process of the utility model crane is that supporting plate is placed on walker tractor or small farm car, the small four-wheel tractor, crane is moved on the building site, start diesel motor, adjust turning to of swing type mechanism, boom angle, pylon height, index drum, just can drive steel rope by the operation cylinder and loosen or tighten up, suspension hook be risen or descend and carry out hoisting operation.
The utility model has the advantages that:
1. the equal scalable of the length of lifting pylon height and arm of derrick adapts to the needs of different sling heights.
2. frame can be done 0~360 ℃ revolution, adapts to the needs of the hoisting operation of different directions.
3. this machine is used as power with diesel engine, suits especially in vast rural area and samll cities and towns' operation of unregulated power supply or electric power supply inconvenience.
4. hoisting crane carries road wheel, and owing to use tractor traction, it is flexible, convenient to move, walk, and suits especially in narrow camp site to move rapidly.
5. crane structure is simple, and full machine total weight is light, and reduced investment is suitable in vast farm building building site and applies.
Below in conjunction with accompanying drawing enforcement structure of the present utility model is described:
Accompanying drawing is the constructional drawing of small-sized lifting crane;
See among the figure: small crane is by component set-ups such as last pylon 10, following pylon 11, arm 7, steel rope 8, suspension hook 9, diesel motor 5, change speed gear box 2 and rollers 1, last pylon 10 supports arm 7, there is regulating mechanism 13 to adjust height on the following pylon 11, frame 15, supporting plate 17, swing type mechanism 14, road wheel 16 and pillar 18 are equipped with in the bottom, swing type mechanism 14 is equipped with joystick 12 and steering handwheel 6,17 of supporting plates can arbitrarily move whole crane on walker tractor or small four-wheel tractor or farm vehicle; One of frame 15 is equipped with diesel motor 5, change speed gear box 2 is equipped with on the next door of diesel engine 5, roller 1 and connecting rod 4 are housed on the change speed gear box, and Wound steel rope 8 on the roller, link on the pulley and suspension hook 9 of arm, connecting rod 4 is linked on the height adjustment mechanism 13 of pylon, be used to regulate the pylon height, luffing mechanism 3 is housed on the frame 15, be connected with arm 7, be used to regulate the angle [alpha] between arm 7 and the pylon, arm is made removable several sections as required.
