Description
Technical field
The present invention relates to a kind of self-balancing extension means for duplex type rope, belong to aerial work platform technical field.
Background technology
Aerial work platform serves the mobility work high above the ground such as every profession and trade work high above the ground, equipment installation, maintenance
Engineering machinery.Aerial work platform mainly has：The types such as scissor-type, vehicular, crank arm type, straight arm type.Aerial work platform has
Have versatility good, can fast transfer, safety, the advantages of quick, be widely used in the engineering construction of work high above the ground.Wherein arm support
Formula (including crank arm type and straight arm type) aerial work platform is because of its travel position compact conformation；Working condition platform can reach
The advantages of height is big with amplitude is widely used.Its arm support generally can quickly stretch and retract, and realize working condition and fortune
The rapid translating of defeated state.
Telescopic arm support is the groundwork mechanism of boom type aerial work platform；Telescoping mechanism is the core for realizing its function
The heart, is typically driven by telescopic oil cylinder, the synchronization telescope motion for realizing single oil cylinder by pulley-rope.For security consideration, stretch
Contracting mechanism is provided with the pulley and rope of two sets of identical sets.During normal operation, two sets of pulley-rope mechanisms are acted on simultaneously, are realized
The stretching motion of arm support；When appearance overload, abrasion or fatigue cause one of which pulley-rope mechanism to fail, another group still
Can normal work, to ensure the safety of operator.
But, as two sets of pulley-ropes cannot ensure that in installation and steel wire tensioning its stress is completely the same, very
To occurring by one of which pulley-rope stress, and another group of then fully relaxed situation；Rope is caused to overload, so as to lead
Cause rope premature failure, strong influence life-span of equipment；Additionally, with the development of high rice number product, the load of extension means
Lotus is increasing, can not meet demand using the rope of single wire rope, generally using two or many steel wire ropes simultaneously now
Connection, two ends are attached using same rope rig, make rope use.But due to the mistake in steel wire rope manufacture process
Difference, the length of many steel wire ropes in same group of rope are different, certainly will produce the uneven situation of each steel wire rope stand under load, make
Larger into a portion steel wire rope stand under load, cause steel wire rope premature failure, affect life-span and the product of rope and extension means
The security performance of product, becomes great potential safety hazard.
Telescoping mechanism is adopted at present increases balance weight to solve the feelings of two sets of pulleys-rope unbalance stress between two ropes
Condition.The program increases balance weight in rope one end, and two ropes are connected with balance weight, draws two ropes by the length for adjusting rope
Power is equal, and now balance weight is located at middle position.If rope extended length is different during use, when bringing difference in length, balance weight
Offset to one side, carry out automatically length compensation, it is ensured that two rope uniform forces.But this scheme needs to adjust rope capacity, leads to
The rope that single wire rope is made often is only applicable to, is unsuitable for rope structure, cannot more solve rope inner cable stress
Uneven problem.
