Description

Be used for the stripping assembly of heavily loaded lifting member

The present invention relates to a kind ofly dismantle lifting member, for example promote a heavily stressed steel cable, wirerope, the device of rope or chain from heavy duty.

When using a lifting member, for example a steel cable is with crane lifting one heavy duty, a building materials that is used for building structure or civil engineering for example, or after a desired location made its unloading, the steel cable that will be engaged with heavy duty by the workman was pulled down usually.

Yet, when the desired location is under water, when for example building or repairing a break-water or river levee, inaccessible this position of workman, steel cable and heavy duty, for example a net cage that stone is housed together promotes in this position, (for example, referring to disclosed Japanese patent application NO.51-12322).

Yet, in these cases,, the net cage of stone for example is housed in order to arrange many heavy duties at seashore or abutment, will increase building cost to each heavy duty as staying about 10, the 000 Yen steel cable of value.So, dismantle steel wire under water by the diver, yet, owing to meteorological conditions or heavily stressed installing condition are difficult to dismounting, so wish to improve field-strip.

In order to address the above problem, applicant of the present invention has applied for the patent (asking NO.3-73986 in the open Japanese Patent of end examination) of the stripping assembly of a heavily loaded lifting member.Wherein, lifting member is located between pedestal and the suspension hook on one, the following lifting member that one cardinal extremity is located on the pedestal engages partly joint with heavily loaded lifting member, its preceding end ring is contained on the bolt of holding up from pedestal, one elastic body upwards pushes away a sliding part that is contained in slidably on the bolt, so that under the no-load situation, the sliding part top cooperates with the top of bolt at least, and when pedestal promoted, the sliding part lowering means overcomes elastomeric elastic force descended sliding part.

When the sliding part lowering means be one hang by sliding part by a suspender weight the time, put down to be contained in the heavy duty with weight and pedestal descends after the preset distance in a desired location in the heavy duty that promotes, the preceding end ring that is contained on the bolt of following lifting member is thrown off from bolt fully.In this case, pedestal is promoted, lifting member is engaged partly from heavily loaded lifting member throw off by hoisting crane.So, can be by using a hoisting crane owing to the out-of-action place of the reason workman of safety and health is provided with heavy duty.

The sliding part lowering means has one to be located at the dead sheave of adopting on the seat, tensile elements one end is contained on the pedestal by pulley, and the hook joint of a release member and hoisting crane, it is formed so that the tensile elements other end can freely engage and unclamp, before heavy duty is put down, the other end of tensile elements is unclamped from release member, make after putting down heavy duty with before pedestal contacts heavy duty and descend the preceding end ring of lifting member to throw off from bolt fully in the desired location.

Yet, in above-mentioned general stripping assembly, may damage because suspender and tensile elements expose the long period.

Under the situation of the stripping assembly of using weight,, when heavy duty is descended, be contained in the heavy duty if heavy duty is four pin cones of a top injustice weight potentially unstable.

In addition, using under the stripping assembly situation of release member, when slinging an other heavy duty in order to put down former heavy duty in the desired location, because the tensile elements that unclamps from release member must engage with release member again, some troubles can appear in operation.

First purpose of the present invention provides a kind of stripping assembly of heavily loaded lifting member, and when putting down heavy duty in a desired location, it can automatically pull down the following lifting member that engages with heavy duty from loading gage.

Heavily loaded 211 the time when putting down in a desired location, bottom steel cable 232 loosens.In this case, substrate 212 is hung by hoisting crane 31, so that pin spare 238 does not contact with heavy duty 211.When draw in the solid line direction of Figure 24

control wire

261 and 261 any the time because the level of arm 257 partly 257b upwards push away the front bottom end of adjusting lever 246, rodmeter 234 unclamps from adjusting lever 246.Rodmeter 234 is owing to self the weight and the first elastomeric elastic force descend, and contacts with pin spare 238.Simultaneously, because putting down of heavy duty 211 and sliding part 218 under the no-load situation rise (Figure 27) owing to the elastic force of first elastic body 211.So the ring 232a of bottom steel cable 232 throws off and the whereabouts from bolt 217.In addition, when coiling hoisting crane steel cable (not shown) rises substrate 212, bottom steel cable 232 from jerk shoe 227 and the steel cable junction surface 211a of heavy duty 211 throw off, and with substrate 212 risings.

In addition, in above-mentioned first embodiment, be by pair of

side plates

14 and 14 and sole piece 16 a pair of

steel plate

13 and 13 be welded to each other form a substrate 12 together.Yet, also can integrally form a substrate with cast steel or cast iron.

First to fourth embodiment uses concrete block as heavy duty with use inverted U-shaped hook as the lifting member junction surface.Yet, also can use cylinder for example the electric light bar or the style of one group of protrusion is arranged such as tetrapod as heavy duty.Under this heavily stressed situation, heavily stressed whole periphery is as the lifting member junction surface, and following lifting member is walked around periphery.

In addition, in the situation of the first and the 4th embodiment, movable sheave is located on the rodmeter, and dead sheave is located on the substrate, and the tensile elements that an end is located on the substrate is walked around movable sheave and dead sheave, and the other end of tensile elements is located on the sliding part.Yet, walk around dead sheave by the other end is located on the sliding part and with tensile elements, and do not need movable sheave.

In addition, in the situation of the first and the 4th embodiment, be that

substrate

12 or 212 is descended in

heavy duty

11 or 211, so that

bottom steel cable

32 or 232 is engaged with the

heavy duty

11 or 211 that will sling, shown in Fig. 3 and 23.Yet, when heavy duty has a rough style such as tetrapod or electric light bar, can be by

substrate

12 or 212 being dropped near heavily stressed ground, sliding part 18 or 118 is descended and pinning, and the front end of

steel cable

32 or 232 is contained on bolt 17 or 117, in this case, again

As implied above, structure of the present invention is to promote substrate by the hook of hoisting crane by lifting member on, the last lifting member that one base end part is located on the substrate engages with heavily stressed lifting member junction surface, one sliding part vertically movably is located on the bolt that is erected on the substrate, overcoming the ring set that makes when the first elastomeric elastic force makes sliding part descend by the sliding part lowering means at lifting member front end down on bolt, temporarily fixedly sliding part lowering means and releasing device unclamp closing appliance to closing appliance when sliding part descends.So when in a desired location heavy duty being put down, releasing device unclamps closing appliance,, the ring of lifting member is thrown off from bolt because the first elastomeric elastic force rises sliding part.So, make the substrate lifting and lifting member is automatically thrown off from heavy duty by hoisting crane.So it can not only save the labour greatly, and can be owing to the out-of-action place of the reason workman of safety and health easily is provided with heavy duty by using hoisting crane.

In addition, by use sliding part lowering means, but rodmeter perpendicular movement ground inserts substrate and stretches out downwards from base plate bottom; One movable sheave is located on the rodmeter rotationally; One dead sheave is located on the substrate rotationally; With a tensile elements, the one end is located on the substrate, and the other end is located on the sliding part, and it passes movable and dead sheave, so that when rodmeter inserts substrate, sliding part is descended; Because the difficult exposure of tensile elements of the present invention and shorter, so compare, stripping assembly of the present invention is not fragile with the common stripping assembly of using a weight---the long and exposure of its suspender and tensile elements---.

In addition, when heavy duty was the object of a top injustice, for example a tetrapod adopt the common stripping assembly of weight stably weight not to be contained in the heavy duty, and the present invention can drop to the desired location with the heavy duty of Any shape.

In addition, in the situation of the common stripping assembly of using releaser, in order to put down another heavy duty of slinging after the former heavy duty in the predetermined area, the tensile elements of taking off from releaser must engage with releaser again, and the present invention does not need this operation.

Particularly, the present invention can use remote control equipment (RCE) easily to put down heavy duty at a distance one.

The stripping assembly that is used for heavily loaded lifting member of the present invention can easily be pulled down a lifting member from a heavy duty, a steel cable for example, and cable wire, wirerope, or chain, heavy duty can be the building materials that building and civil engineering operation are used, and can repeatedly use lifting member.
