Abstract
The utility model discloses a kind of movable pulley yoke of marine crane, relate to marine crane manufacturing technology field, including multiple assembly pulleys being welded on crossbeam by bracing frame, the two ends of described crossbeam are equipped with installing plate, and two pieces of described installing plates are articulated and connected by forward press and the back stay of hinge with tripod respectively.Compared with prior art, the dismounting of movable for marine crane pulley yoke, when transport, can be departed from tripod, convenient transhipment by the movable pulley yoke of this marine crane.
Description
Technical field
This utility model relates to marine crane manufacturing technology field, a kind of tripod for marine crane
Pulley yoke.
Background technology
Marine crane tripod pulley yoke, connects and coordinates on tripod, and variable-amplitude steel wire rope is by being assemblied in tripod
The pulley action of pulley yoke, reaches the action of whole crane amplitude variation.There is a kind of marine crane pulley yoke as shown in Figure 1,
This marine crane pulley yoke includes the assembly pulley 01 being welded on crossbeam 03 by bracing frame 02, the installing plate of crossbeam 03 one end
04 inserts and is welded on the back stay 05 of tripod, and the installing plate of crossbeam 03 other end 04 is inserted and is welded on the forward press 06 of tripod.This
In use there are the following problems to plant marine crane pulley yoke: 1, produced on-site manufacturability is poor, due to propping up of assembly pulley
Support must with tripod welding equipment after, just can be machined out, such total part is relatively big and weight, to lathe and lifting location
The elevating capacity of driving requires higher；And when welding, the forward press of tripod and back stay need on-the-spot scarfing, and manufacturability is numerous
Trivial, it is unfavorable for quality control；2, because can not dismantle, during transhipment, fixed pulley yoke need to transport with tripod simultaneously, numerous
Trivial and cost of transportation is high；3 and marine crane pulley yoke suffered by pulling force except acting on crossbeam, also pulling force is delivered in it
With on the weld seam of tripod, reduce the service life of tripod.
Utility model content
The problem that this utility model is solved is to provide a kind of movable pulley yoke of the marine crane being readily transported.
In order to solve the problems referred to above, the technical solution adopted in the utility model is: the movable pulley of this marine crane
Frame includes multiple assembly pulley being welded on crossbeam by bracing frame, and the two ends of described crossbeam are equipped with installing plate, described in two pieces
Installing plate is articulated and connected by forward press and the back stay of hinge with tripod respectively.
In above-mentioned marine crane movable pulley yoke technical scheme, more specifically technical scheme is it may also is that described
The top of forward press and described back stay is provided with hinged seat, described hinged seat have two pieces be arranged in parallel with hinge installing hole
Gripper shoe, described installing plate be inserted between described two pieces of described gripper shoes and by sequentially pass through two pieces of described gripper shoes and
The hinge of described installing plate is connected with described hinged seat, is equipped with described installing plate with one of in one end of described hinge
The locking nut that described gripper shoe abuts against.
Further: multiple described assembly pulleys are vertically in being distributed on described crossbeam.
Further: described crossbeam is cylinder, multiple described assembly pulleys are radially in being distributed in described crossbeam
On circumference.
Owing to have employed technique scheme, this utility model compared with prior art has the advantages that 1, cuts with scissors
Installing hole in joint chair gripper shoe can first pass through boring machine and complete processing, is using scene, only need to carry out assembling by hinge,
Produced on-site processing performance is not preferable；2, during transport, the dismounting of movable for this marine crane pulley yoke installing plate can be departed from
Tripod, convenient transhipment；3, structural member stress is good, and pulling force suffered by movable pulley yoke acts on crossbeam, passes through hinge simultaneously
Being delivered on tripod, by contrast, hinge is more preferable by force rate weld seam stress, is also easier to carry out quality control.
Accompanying drawing explanation
Fig. 1 is the structural representation of the movable pulley yoke of existing marine crane.
Fig. 2 is the structural representation of this utility model embodiment.
Detailed description of the invention
The utility model is described in further detail for example below in conjunction with the accompanying drawings:
Embodiment 1:
The movable pulley yoke of marine crane as shown in Figure 2 includes multiple cunning being welded on crossbeam 3 by bracing frame 2
Wheels 1, multiple assembly pulleys 1 of the present embodiment are vertically in being distributed on crossbeam 3；The two ends of crossbeam 3 all weld one piece to be had
Installing plate 4, two pieces of installing plates 4 at crossbeam 3 two ends are respectively by hinge 7 and the forward press 6 of tripod and the hinged company of back stay 5
Connect；All be welded with a hinged seat at the top of forward press 6 with back stay 5, this hinged seat have two pieces be arranged in parallel with
The gripper shoe 9 of hinge installing hole, two pieces of gripper shoes 9 are welded on the top of forward press 6, and two pieces of gripper shoes 9 are welded on back stay 5
Top；Two pieces of installing plates 4 at crossbeam 3 two ends are inserted between forward press 6 and two pieces of gripper shoes 9 at back stay 5 top also respectively
It is connected with hinged seat by sequentially passing through the hinge 7 of two pieces of gripper shoes 9 and installing plate 4, is respectively arranged with will install in one end of hinge 7
The locking nut 8 that plate 4 abuts against with one of gripper shoe 9.
Embodiment 2:
Crossbeam 3 is cylinder, and multiple assembly pulleys 1 are vertically in being distributed on crossbeam 3, radially in being distributed in
On the circumference of crossbeam 3 outer rim；Other features are same as in Example 1.
