Description
Technical field
The utility model is related to engineering machinery correlative technology field, is to be related to a kind of crane amplitude variation steel wire specifically
Rope is anti-to kink device and crane.
Background technology
Current large-scale arm tower crane represents the present age weight of big elevating capacity, big elevating height, big lifting velocity
Type building crane.Large-scale arm tower crane arm design uses " bar " structure, relative to flat arm derrick crane " beam "
More preferably, it is smaller that boom structure accounts for complete machine structure proportion to structural stability can, and the biggest lifting capacity is then bigger.
Arm tower crane jib lubbing mechanism is required to meet material handling operating position, makes full use of rising for itself
Ability (amplitude is reduced and can improve lifting capacity) is hung, the operating mechanism of change amplitude is realized, and for expanding the work of derrick crane
Make scope, improve productivity ratio.Jib lubbing mechanism is made up of rack winch, steel wire rope, assembly pulley etc..
When arm tower crane variable-amplitude steel wire rope uses brand-new steel wire rope, due to there is itself very big torsion in steel wire rope
Power, easily kinks after coming into operation.Variable-amplitude steel wire rope influences the normal of tower crane to use after kinking, the armed lever that rises and falls can cause luffing
, there are major safety risks in steel wire rope heavy wear.
Steel wire rope solution after kinking is typically to carry out to put the treatment that disappears, i.e., the number of turns reversed according to luffing assembly pulley come
Determine the number of turns of wirerope-winding, the fixing end by variable-amplitude steel wire rope from hoist engine is extracted out, carry out turn-back, and will reverse
Steel wire rope afterwards is reattached on elevator machine cylinder.Needs arrive on luffing assembly pulley the strength of torsion, carry out the armed lever 2 that rises and falls
To 3 times.Single reverses the number of turns no more than 5 circles, and more than 5 circles, the strength that steel wire rope is kinked is excessive, it is easy to damage steel wire rope
(snuff), that is, can not once be completed, it is necessary to repeatedly can just take effect by the above-mentioned broken step that disappears.So that a large amount of labours
And the working time.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, there is provided a kind of crane amplitude variation steel wire rope is prevented

Layer Interal fixation connection, upper strata steel plate is connected by fastener with lower floor Interal fixation.
Preferably, the linking arm is channel-section steel.
Preferably, the fastener is bolt.
Provide it is above-mentioned it is anti-kink device while, the utility model provides a kind of derrick crane, the tower lifting
Machine has tower body, left side running block, left side variable-amplitude steel wire rope group, middle wirerope group, right side running block and right side luffing
Steel wire rope group,
Any group of running block is respectively provided with flat board, be provided with the derrick crane it is above-mentioned it is anti-kink device, wherein,
Each flat board is fastened by bolts by upper strata steel plate and lower floor's steel plate clamping, upper strata steel plate and lower floor's steel plate；
Linking arm separates at least steel cable of middle wirerope group；
Two steel pipes respectively by with each separated with least steel cable of corresponding steel wire rope group.
Used as more preferably scheme, the utility model is additionally provided a kind of installs above-mentioned anti-kink on existing derrick crane
The method of device, step is as follows：
A, linking arm is made through middle wirerope group, middle wirerope group is connected arm and be divided into upper and lower two parts；
B, by be located at the left and right sides upper strata steel plate be positioned on the arm-tie of derrick crane, and the left and right sides steel pipe will
Each self-corresponding steel wire rope component is divided into left and right two parts；
, be fastened as a whole for upper strata steel plate, arm-tie and lower floor's steel plate by bolt by C, the setting lower floor steel plate below arm-tie.
The beneficial effects of the utility model are：
(1) present apparatus simple structure, can be drawn materials at the construction field (site), it is only necessary to common channel-section steel, common steel tube, steel plate
Just making can be processed, cost is very low.It is flexible and convenient to use, repeatable to utilize, greatly save because steel wire rope kinks generation
Put consumption use.
(2) present apparatus is connected by bolt and upper and lower two blocks of steel plates with luffing running block, is not required to use welding manner,
Be conducive to the protection of derrick crane.
(3) length of channel-section steel determines according to two running block centre distances, it is ensured that steel pipe is vertical with channel-section steel, will not change in addition
Become the Impact direction of running block and variable-amplitude steel wire rope.
(4) follow-up maintenance is not needed after device installation.
