Description
Technical field
the present invention relates to technical field of crane equipment, be specially a kind of arrangement of clutch of Lever Blocks.
Background technology
lever Blocks pulls spanner by manpower manual, and by lever principle, thus obtain the straight line tractive force matched with load, thus drive weight to realize moving up and down.Because Lever Blocks volume is little, lightweight, therefore carry and operate all very convenient, be applicable to the weight of less tonnage, the arrangement of clutch structure of existing Lever Blocks is general more complicated, operation is compared wastes time and energy, the switching underaction of mode of operation, due to the relation of this body structure, distribution of force is optimized not enough, load-carrying capacity is strong not enough, stable not enough also smooth and easy not enough during operation, operational process easily easily causes damage to load or Lever Blocks itself, and service life is long not enough.
Summary of the invention
an object of the present invention is to provide that a kind of structure is simple effectively, use safety is stablized, simple to operate again flexibly and load-carrying capacity is stronger, the arrangement of clutch of the better Lever Blocks of braking effect.
above-mentioned technical purpose of the present invention is achieved by the following technical programs: a kind of arrangement of clutch of Lever Blocks, comprise, with the major axis of Lever Blocks, the brake seat be connected is installed, described major axis is through the front wallboard of Lever Blocks, described brake seat is positioned at the front side of front wallboard, the installation disk that brake seat comprises end disk and extended to form to front side by end disk, the periphery of described installation disk by end disk to front side to being arranged with the first friction lining successively, ratchet and the second friction lining, described major axis is also provided with and is positioned on front side of the second friction lining and there is the stop-off nut against plane that can lean with described second friction lining, disk and stop-off nut are installed relative to the sidepiece of side offering corresponding annular groove and inserting the termination of the rear and front end of a brake spring respectively, in the wrench device that position, described stop-off nut periphery is arranged at Lever Blocks and its position, front end is also connected with handwheel.
in technique scheme, integrally-built connectivity is better, distribution of force is more superior, structural strength is higher, run more stable, be convenient to the carrying out of the load lift work of efficient stable, load-carrying capacity is stronger, safety is higher, also be more not easy impaired, braking effect is better, structure is relatively simple, part is few, faster and more convenient operation, the switching of mode of operation is more flexible, anticlockwise direction rotates handwheel when empty, handwheel drives stop-off nut to rotate, stop-off nut is produced move axially, owing to placed brake spring between brake seat and stop-off nut, this spring is Compress Spring, brake seat under the effect of elastic force, first, second friction lining, ratchet, gap has all been there is between stop-off nut, be not in contact with each other between each friction surface, now drop hoisting chain, elastic force due to brake spring is greater than the axial force that major axis is formed because of rotation, make first, still there is gap between each friction surface of the second friction lining not contact, such hoisting chain just can freely pull, when hoisting chain load, because load effect makes the axial force of major axis be greater than the elastic force of brake spring, brake spring is compressed, brake seat, first, second friction lining, ratchet, gap would not be there is between stop-off nut, each friction face abuts against each other braking, hoisting chain is stoped to move, support load, time unloaded, stop mechanism is in the state of getting loose, arbitrarily can drop hoisting chain, once load, stop mechanism is braking operation immediately, drag the switching simple and flexible between chain and work two states.
as to preferably of the present invention, handwheel is provided with the protruding reinforcing rib for being connected with the position, front end of stop-off nut.Optimize structure further, connectivity is better, and make structural strength higher, distribution of force is optimized more, and load-carrying capacity is stronger, and braking effect is better, runs safety and stability more, is also not easy to cause damage to itself and load.
as to preferably of the present invention, comprise two ratchets be all meshed with ratchet be all arranged on by detent pin on front wallboard.Optimize structure further, connectivity is better, and make structural strength higher, distribution of force is optimized more, and load-carrying capacity is stronger, and braking effect is better, runs safety and stability more, is also not easy to cause damage to itself and load.
as to preferably of the present invention, two described detent pin axle centered by major axis is centrosymmetric.Optimize structure further, connectivity is better, and make structural strength higher, distribution of force is optimized more, and load-carrying capacity is stronger, and braking effect is better, runs safety and stability more, is also not easy to cause damage to itself and load.
as to preferably of the present invention, the surface of major axis has multiple screw thread, end disk and install the centre of disk offer vertically be communicated with pass for major axis and be arranged on the center mounting hole on the multiple screw thread of major axis, the centre of stop-off nut offer vertically can be set in major axis multiple screw thread on and along major axis by spinning movement can before and after the center moving hole of advance and retreat.Optimize structure further, connectivity is better, and make structural strength higher, distribution of force is optimized more, and load-carrying capacity is stronger, and braking effect is better, runs safety and stability more, is also not easy to cause damage to itself and load.
as to preferably of the present invention, the forward end of major axis is provided with throttled nut, and handwheel sleeve is located on the position on major axis between throttled nut and stop-off nut.First, the determining positions of the throttled nut size of handwheel endplay,, also optimize structure further, connectivity is better meanwhile, make structural strength higher, distribution of force is optimized more, and load-carrying capacity is stronger, and braking effect is better, run safety and stability more, be also not easy to cause damage to itself and load.
as to preferably of the present invention, throttled nut is fixing with on major axis by spring cotter.Also optimize structure further, connectivity is better, and make structural strength higher, distribution of force is optimized more, and load-carrying capacity is stronger, and braking effect is better, runs safety and stability more, is also not easy to cause damage to itself and load.
