Description
Technical field
The utility model belongs to hoisting and hanging device, is related to crane hoisting equipment design and application method.
Background technique
At present China's lifting equipment mainly have bridge crane, gantry crane, arm derrick crane, small-sized reset
It is standby etc..Gantry crane is applied relatively broad in our engineering construction fields, and the girder application form of gantry crane is main
It is divided into single girder and double girders.Main beam structure is mainly the structures such as box beam, girder truss, Honeycomb Beam, and most common is box beam and purlin
It sets a roof beam in place, the girder trolley regardless of structure type is all to ride to be pressed at the top of girder on walking rails or be suspended from
The lower part of girder.If it is relatively more limited to lift site space, therefore is also just limited by hoisting height, certain journey is brought to operation
The inconvenience of degree.
Utility model content
The purpose of this utility model is that: for the trolley of single girder crane, a kind of Novel structure is designed, is utilized
Horizontal space saves down space on girder, vacates maximum lifting space in certain space limitation range to crane, with
Meet job requirements.
The utility model mainly fundamentally changes vehicle structure form, is changed to side hanging from original overhead or suspension type
The hoist crane of trolley is placed side by formula, and trolley travelling track is mounted on single-beam side, carries trolley, lifting
Trolley total is similar to a frame structure " embracing " on single-beam.
Trolley mainly walks cross girders, connection structure frame, pulley mounting platform, fixed pulley group, electronic by trolley
Hoist crane composition.It is the box-structure that steel plate is welded, bottom hollow out that trolley, which walks cross girders,.Close to rear and front end phase
The position installation traveling steel wheel answered, traveling steel wheel are built in box cavity, and steel wheel tyre tread is lower than tank floor.Total is left
Right each trolley walks cross girders, and two trolleys are walked cross girders and connected by the connection structure frame that tubing is made, will
Total forms a closed ring structure.It is sliding in the corresponding position welded pulley mounting platform in the left and right sides of structure
Wheel mounting platform is mainly welded by angle steel and tubing, is mainly used for installing fixed pulley group and support electric hoist.It is fixed
Pulley blocks are made of two pulleys, are respectively installed on the mounting platform of the left and right sides.Electric hoist is formed in the market
CD type electric hoist with speed reducer.It is installed on the vertical tubing of frame structure, is seated pulley mounting platform.Such as figure
Shown in 1
The utility model compared with prior art, mainly there is following advantage:
1, the vertical occupied space of girder truss is reduced using circumferential type structure, provides space for lifting.
2, it is adapted to the crane of all single girders.
3, the stability of single girder trolley is improved using circumferential type structure.
Detailed description of the invention

Fig. 2 a-2c is that a kind of encircling type single-beam operation trolley uses schematic diagram
Description of symbols in figure
1 trolley walks cross girders, 2 connection structure frames, 3 pulley mounting platforms, 4 fixed pulley groups, 5 electric hoistings
Cucurbit, 6 single girders.
Specific embodiment
For make the utility model aim, principle and construction become apparent from it is clear, below in conjunction with drawings and the specific embodiments make into
One step illustrates
A kind of embodiment 1: structure composition of encircling type single-beam operation trolley
In order to achieve the above objectives, the utility model mainly fundamentally changes vehicle structure form, from original overhead or
Person's suspension type is changed to side hanging, the hoist crane of trolley is placed side, trolley travelling track is mounted on single-beam side, holds
Trolley is carried, trolley total is similar to a frame structure " embracing " on single-beam.Trolley is mainly by lifting
Trolley is walked cross girders 1, connection structure frame 2, pulley mounting platform 3, fixed pulley group 4, electric hoist 5 and is formed.Trolley
Walking cross girders 1 is the box-structure that steel plate is welded, bottom hollow out.Traveling steel is being installed close to the corresponding position in rear and front end
Wheel, traveling steel wheel are built in box cavity, and steel wheel tyre tread is lower than tank floor.Each trolley traveling of total or so
Beam, two trolleys are walked the connection structure frame 2 that cross girders is made by tubing and are connected, and total is formed a closing
Ring structure.In the corresponding position welded pulley mounting platform 3 in the left and right sides of structure, pulley mounting platform 3 is mainly by angle
Steel and tubing are welded, and are mainly used for installing fixed pulley group 4 and support electric hoist 5.Fixed pulley group 4 is by two pulleys
Composition is respectively installed on the mounting platform 3 of the left and right sides.Electric hoist 5 is the CD with speed reducer being formed in the market
Type electric hoist.It is installed on the vertical tubing of frame structure, is seated pulley mounting platform 3.As shown in Figure 1
A kind of application method of the encircling type single-beam of embodiment 2 operation trolley
1, according to single-beam sectional dimension and walking rails installation site, determine that 2 size of connection structure frame, group load
Weight trolley is mounted on single-beam, can be moved back and forth under the traction of driving force along walking rails.
2, connection control system and power supply line make electric hoist 5 in can working condition.
3, operation control system runs trolley to lifting object, and operation control system, which falls, lifts wirerope,
Connecting steel wire ropes and lifting object, determine securely after, boom hoist cable slings object, traveling hoist equipment by lifting object send to
Designated place.
4, lifting object is transferred and is landed by operation control system, and fine-tuning contraposition is placed.Rigging out promotes lifting steel wire
Rope.
Next place's operation can be carried out by repeating the above steps.
