Description
Technical field
The present invention relates to a kind of weight-lifting equipment, specifically refer to power station overhead traveling crane mechanism.
Background technology
Transfer crane is the one distortion of crane in bridge type, is mainly used in the loading and unloading operation of outdoor goods yard, stock ground goods, bulk goods.Its metal construction is as door-shaped frame, and install two legs under support main beam, can directly walk on the track on ground, girder two ends can have overhanging cantilever beam; Transfer crane has the features such as utilization of area rate is high, scope of work large, it is wide to adapt to, highly versatile, is used widely in goods yard, harbour.Gauntry crane is the one in transfer crane, and gauntry crane is primarily of main beam structure, supporting leg, walking beam, walking structure, electrical equipment, ladder driver's cab composition; Gauntry crane agent structure is plate weldering box-structure, girder and supporting leg can be divided into some sections, refine high strength bolt by gusset plate and M24B level between sections to connect, there is the features such as convenient transportation, dismounting is flexible, spelling group speed is fast, and 25m, 20m, 17m, 12m different spans can be combined into respectively as required, the different lifting altitude of 16m, 12m, 7m, 3m, is applicable to the operating needs of on-the-spot different condition; Traveling mechanism of the larger traveller adopts two-wire chassis, " three-in-one " driver train, bogie frame and supporting leg hinged, to overcome the wheel unbalance stress that track laying error causes; Crane carriage operating unit is that " three-in-one " drives, and lifting mechanism adopts frequency conversion speed-adjusting system, realizes infinite speed variation, makes to set a roof beam in place operation steadily, improves the safe reliability of operation of setting a roof beam in place; And be bolt or pin shaft joint between each primary member of gauntry crane, make the transport of gauntry crane, installation and transition operation conveniently, fast and safely.
Gauntry crane is also a kind of equipment that oil field is commonly used simultaneously, and it drives walking wheel to rotate by actuating device, thus realizes the movement of whole gauntry crane on rail.Existing gauntry crane mobile device is mainly through chain gear, and chain, by each for the transmission of power of actuating device walking wheel, drives walking wheel to rotate, thus realizes the movement of lifting object; But this kind of structure also also exists certain defect, and its problem is simultaneously, when loads is just by lifting, loads can produce rocking in horizontal direction, and the safety factor in operating environment is reduced.
Summary of the invention
The object of the present invention is to provide power station overhead traveling crane mechanism, while facilitating goods quick travel, ensure the stability of hanging mechanism work, safety.
Object of the present invention is achieved through the following technical solutions:
Power station overhead traveling crane mechanism, comprise cross bar, at described cross bar two ends, fixed block is installed, in the middle part of cross bar, chain connection has cross swing arm, and the vertical component effect lower end of described swing arm is connected with hook, and described fixed block offers blind hole, the downside inwall of blind hole is provided with roller, the horizontal part two ends of described swing arm have groove, and roller-coaster is arranged in groove, and the horizontal part two ends of swing arm are connected with blind via bottom by spring; Also comprise two assembly pulleys be arranged on cross bar, and two described assembly pulleys are symmetricly set on the both sides of swing arm.When the present invention works, assembly pulley walked around by the steel wire of hoisting crane, loads is fixed on hook, hoisting crane starts to start, when hanging mechanism moves, hook can produce to swing and loads is aloft rocked, make in operating environment, to leave larger potential safety hazard, cross swing arm and cross bar hinged, swing arm is moved with loads, the horizontal part two ends of swing arm are placed in fixed block, roller in blind hole is free to slide in groove, when loads swings left, the horizontal part end of swing arm being positioned at left side in blind hole to left movement, spring stress be compressed into and give one, swing arm end elastic force to the right, when roller contacts with the end of groove, swing arm stop motion, the horizontal end being simultaneously positioned at the swing arm on right side is same to left movement in blind hole, and the spring being positioned at right side blind hole is stretched, for swing arm provides a pulling force to the right, by the force balance of swing arm both sides, rocking that loads is produced is eliminated between two fixed blocks, and then reach the stress balance of horizontal direction of hook place and loads, ensure the stable of loads, while quick travel, greatly improve the safety of high-altitude hanging.
In the middle part of described groove, be provided with a slide rail, and described roller is track roller, track roller coordinates with slide rail.When loads moves, owing to linking up with the gravity of own and loads, make roller be subject to larger downforce, affecting it provides stable support power; The slide rail arranged in the middle part of groove engages with track roller, and the slip that slide rail is roller provides directional tagging, avoids roller to produce deformation when stressed and causes roller can not normally movement.
The horizontal length of described groove is less than the degree of depth of blind hole.Roller-coaster is arranged in groove, when roller contacts with groove ends, swing arm stops mobile, the length of groove is set to the degree of depth being less than blind hole, the horizontal part end of swing arm Compress Spring when mobile can be ensured, when spring arrives maximum compressibility, prevent swing arm from continuing mobile to avoid spring supercompression and impaired.
Described assembly pulley comprises the large pulley and small sheave that are arranged side by side.As preferably, assembly pulley comprises a large pulley and a small sheave, makes two ends, whole hanging structure left and right uniform force when steel cable is wound around on assembly pulley, reduces the stability of loads when high-altitude is moved further.
The present invention compared with prior art, has following advantage and beneficial effect:
1, power station overhead traveling crane mechanism of the present invention, when loads swings left, the horizontal part end of swing arm being positioned at left side in blind hole to left movement, spring stress be compressed into and give one, swing arm end elastic force to the right, when roller contacts with the end of groove, swing arm stop motion, the horizontal end being simultaneously positioned at the swing arm on right side is same to left movement in blind hole, and the spring being positioned at right side blind hole is stretched, for swing arm provides a pulling force to the right, by the force balance of swing arm both sides, rocking that loads is produced is eliminated between two fixed blocks, and then reach the stress balance of horizontal direction of hook place and loads, ensure the stable of loads, while quick travel, greatly improve the safety of high-altitude hanging,
2, power station overhead traveling crane mechanism of the present invention, the slide rail arranged in the middle part of groove engages with track roller, and the slip that slide rail is roller provides directional tagging, avoids roller to produce deformation when stressed and causes roller can not normally movement;
3, power station overhead traveling crane mechanism of the present invention, assembly pulley comprises a large pulley and a small sheave, makes two ends, whole hanging structure left and right uniform force when steel cable is wound around on assembly pulley, reduces the stability of loads when high-altitude is moved further.
