Description
[ technical field ] A method for producing a semiconductor device
The invention relates to a combined type ring chain electric hoist of a trolley special for wind power, in particular to a combined type ring chain electric hoist of a small-turning four-wheel double-trolley special for wind power, which is used as special equipment for hoisting wind power generation equipment.
[ background of the invention ]
The conventional thread jacking device of the combined type loop chain hoist of the trolley comprises a locking block, a rubber block fixed on the top surface of the locking block and a locking rod in threaded connection with a connecting frame, wherein the locking rod extends out of the upper end of the connecting frame and is fixedly connected with the locking block, and the rubber block corresponds to the bottom surface of a track beam.
During locking operation, the locking rod is rotated clockwise to move upwards relative to the connecting frame, so that the rubber block is pushed to the bottom surface of the track beam, and the connecting frame, the trolley fixed on the connecting frame and the chain block fixed on the connecting frame are stopped at the bottom of the track beam together; when the locking is required to be released, the locking rod is rotated anticlockwise to move downwards relative to the connecting frame, so that the rubber block is separated from the bottom surface of the track beam instantly, and the trolley device can be restored to slide on the track beam.
Because the existing screw thread jacking device only depends on a locking mechanism of screw thread jacking force, once the screw thread is loosened, the locking is easy to lose efficacy, and after a gap is formed between the rubber block and the bottom surface of the track beam, the trolley combined type chain hoist is not still, so that the existing screw thread jacking device is necessary to be improved.
The internal space of the wind power generator bin is compact, the object lifting opening needs to be arranged at the tail of the wind power generator bin due to the self structural relationship, however, the tail space of the wind power generator bin is narrower, and therefore the conventional universal electric chain hoist cannot be used for lifting wind power equipment at high altitude.
[ summary of the invention ]
The invention aims to provide a special wind power small-turning four-wheel double-trolley combined type loop chain electric hoist with high integration level and elastic locking.
Therefore, the invention adopts the following technical scheme:
special little turn four-wheel double-trolley combined type ring chain electric block for wind power generation, include that it links firmly a pair of preceding wallboard to hang the roof beam before through, link firmly the components of a whole that can function independently combination four-wheel double-trolley and the chain guide mount of a pair of back wallboard through the back string roof beam, be fixed in the bearing frame of leading its upper end of chain mount, install the check lock lever of chain electric block and threaded connection chain guide mount in the bearing frame bottom, a pair of preceding wheel of locating preceding wallboard and a pair of back wheel of locating the back wallboard support together on the track roof beam, its improvement point lies in: the mechanism comprises a bearing frame, a front suspension beam, a rear suspension beam, a suspension ring plate, a bearing shaft and a bearing, wherein the bearing shaft is arranged at each end of the bearing frame and in the corresponding suspension ring plate; the upper end of each vertical shaft extending out of the bearing frame is sleeved with a locking block in an empty way, a rubber block fixed on the top of the locking block is positioned on the bottom surface of the track beam, and a compression spring is arranged between the locking block and the bearing frame; the outer peripheral wall of the locking block is provided with an annular groove; the guide chain fixing frame is provided with a lever piece, the lower end of the lever piece is placed at the top end of the locking rod, and the upper end of the lever piece is clamped in the annular groove.
When the locking rod moves upwards and pushes the lower end of the lever piece, the rubber block is separated from the contact with the bottom surface of the track beam; when the locking rod moves downwards, the locking block drives the rubber block to be pressed against the bottom surface of the track beam under the action of the restoring force of the compression spring.
In order to improve the lifting height of the invention to fully embody the characteristic of low clearance, the electric chain hoist arranged at the bottom end of the bearing frame approaches the bottom edges of the front wall plate and the rear wall plate.
The invention has the following advantages and positive effects:
the invention integrates a split combined four-wheel double trolley turning mechanism sliding on a track beam and an anti-slip elastic locking device for keeping a trolley combined type ring chain electric hoist on the track beam to prevent accidental movement, the rotation of a vertical shaft not only drives a bearing frame and a suspension ring plate to enable the split combined four-wheel double trolley to integrally turn and walk along with wheels, thereby meeting the requirements that the invention can be roughly positioned at the turning position of the track beam and the lifting position of a lifting port approaching the tail part of a corresponding machine cabin, but also can be positioned at an accurate lifting point position by operating the elastic locking device, thereby meeting the requirements of safe and reliable high-altitude lifting operation of wind power equipment.
Because the hanging beam of the four-wheel double trolley is additionally provided with the hanging ring plate, the vertical shaft and the bearing are arranged between the hanging ring plate and the bearing frame to form the turning mechanism, the lever part is additionally arranged between the bearing frame and the guide chain fixing frame, and the compression elasticity is additionally arranged between the locking block arranged on the vertical shaft and the bearing frame, so that the elastic locking device is formed, and the characteristics of high integration level and compact space structure of the turning mechanism and the elastic locking device are fully embodied.
The locking device is locked on the bottom surface of the track beam by means of the elasticity of the compression spring, so that the locking device has the characteristics of high stability and reliability under the condition of continuously keeping a locking anti-slip state when the locking device is not used at a preset position, the wind power equipment is prevented from being impacted by accidental sliding on the track beam due to mechanical vibration of wind power machine cabin equipment and high altitude high wind power, the adverse effect on the trolley combined type ring chain electric hoist caused by mechanical vibration and wind power vibration is overcome, and compared with a thread tightening device with the existing structure, the defect that the thread tightening force is easy to lose efficacy due to thread loosening is overcome.
