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.
Summary of the invention
It is an object of the invention to: for the trolley of single girder crane, a kind of Novel structure is designed, transverse direction is utilized
Down space on girder is saved in space, maximum lifting space is vacateed in certain space limitation range to crane, to meet
Job requirements.
The present invention mainly fundamentally changes vehicle structure form, is changed to side hanging from original overhead or suspension type,
The hoist crane of trolley is placed into side, trolley travelling track is mounted on single-beam side, carries trolley, 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
A kind of application method of encircling type single-beam operation trolley.
1, it according to single section parameter and walking rails installation site, determines connection structure frame size size, assembles
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 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.
Compared with prior art, the present invention 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. 1 a-1d is that a kind of encircling type single-beam runs trolley composite structural diagram
Fig. 2 a-2c is that a kind of encircling type single-beam operation trolley uses schematic diagram
Description of symbols in figure

Specific embodiment
It is clear to become apparent from the object of the invention, principle and construction, make below in conjunction with drawings and the specific embodiments further
It illustrates
A kind of embodiment 1: structure composition of encircling type single-beam operation trolley
In order to achieve the above objectives, the present invention mainly fundamentally changes vehicle structure form, from original overhead or suspension type
It is changed to side hanging, the hoist crane of trolley is placed into side, trolley travelling track is mounted on single-beam side, and carrying lifting is small
Vehicle, trolley total are similar to a frame structure " embracing " on single-beam.Trolley is mainly by trolley traveling
Beam 1, connection structure frame 2, pulley mounting platform 3, fixed pulley group 4, electric hoist 5 form.Trolley walks cross girders 1
The box-structure that steel plate is welded, bottom hollow out.Traveling steel wheel, traveling steel wheel are being installed close to the corresponding position in rear and front end
It is built in box cavity, steel wheel tyre tread is lower than tank floor.Each trolley of total or so walks cross girders, two liftings
Trolley is walked the connection structure frame 2 that cross girders is made by tubing and is connected, and total is formed a closed 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 welded by angle steel and tubing
It forms, is mainly used for that fixed pulley group 4 and support electric hoist 5 are installed.Fixed pulley group 4 is made of two pulleys, each to install
In on the mounting platform 3 of the left and right sides.Electric hoist 5 is the CD type electric hoisting calabash with speed reducer being formed in the market
Reed.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
