Description
Technical field
It the utility model is related to a kind of arm and shelve locking device, belong to engineering machinery field, and in particular to a kind of multiple spot
The arm of balance elevation angle adjustable shelves locking device.
Background technology
With the development of engineering equipment industry, for crane gear also towards maximization, multifunction high speed development, its is medium-and-large-sized
The boom structure of boom type ship's crane and its deadweight are also increasing, and its structure type is mostly steel pipe truss structures, is dragged
Stress point is few when boat is shelved, and is more vulnerable to damage, and existing arm shelving unit is mostly single-point or 2 points of supports, can not be expired
The demand of the large-scale boom type ship's crane of foot, therefore, it is necessary to it is a kind of with large-scale boom type marine crane boom structure and from
The supporting arm of heavy phase shelves locking device.
Utility model content
The utility model is mainly to solve the above-mentioned technical problem present in prior art, proposes that a kind of multiple equilibrium can
The arm at the elevation angle is adjusted to shelve locking device.The device and method can provide multi-point support when arm is shelved for it, and adaptive
The arm elevation angle, balanced support power are answered, and locks arm, ensures that it shelves the stabilization of state, is meeting the same of Large Sized Jib deadweight
When, prevent boom structure from causing to damage because shelving operating mode.
Above-mentioned technical problem of the present utility model is mainly what is be addressed by following technical proposals：
A kind of arm of multiple equilibrium elevation angle adjustable shelves locking device, including：
Support, the equalizer bar being articulated with support, positioned at balancing spring of the equalizer bar with respect to both sides, it is arranged at purlin under arm
Locking otic placode is set on frame, the locking device being engaged with the locking otic placode being arranged on equalizer bar.
Optimization, a kind of arm of above-mentioned multiple equilibrium elevation angle adjustable shelves locking device, and arm connects with equalizer bar
Tactile position is provided with yielding rubber.
Optimization, a kind of arm of above-mentioned multiple equilibrium elevation angle adjustable shelves locking device, and the locking device includes：
By locked cylinder drive bearing pin, be arranged at balance beam support on locking shaft hole, it is described locking otic placode on be provided with it is described
The elongated hole that locking shaft hole is engaged, the bearing pin can the locked cylinder be driven through the elongated hole after be inserted into lock
In dead axle hole.
Optimization, a kind of arm of above-mentioned multiple equilibrium elevation angle adjustable shelves locking device, and the equalizer bar includes：It is flat
Weigh beam support, the suspension arm support seat being arranged above balance beam support opposite sides；The balancing spring is arranged at suspension arm support
Seat lower section；The balance beam support is articulated with support by the boss in the middle part of it；It is provided with the suspension arm support seat
The groove to match with arm contact site.
As described above, it is known that, the utility model compared with prior art, has the advantages that：
(1) former single-point or 2 points of supports are changed to multi-point support, with the support force of the mode equilibrium each point of equalizer bar,
Enabling capabilities are effectively increased, and elevation angle when arm is put upside down can be adapted to automatically.
(2) strong point is transferred on newly-installed crossbeam by the main limb of former arm truss, and set in the strong point
There is yielding rubber, the keyed end of locking device is also transferred on newly-installed crossbeam by the main limb of arm truss, makes arm in energy
Its primary structure is effectively avoided to be damaged when shelving while bearing bigger reaction of bearing.
(3) locking device is controlled by oil cylinder, convenient and swift and safer without manual operation.
Therefore, the present apparatus can meet that the arm of large-scale boom type ship's crane shelves requirement, provide bigger branch
Support force and while shelving state of stabilization, effectively avoid arm primary structure from being damaged when shelving.

Fig. 4：Arm shelves state left view Local map.
Embodiment
Below by embodiment, and with reference to accompanying drawing, the technical solution of the utility model is described in further detail.
Embodiment：
When crane arm 1 is not shelved on rest stand, equalizer bar 6 can be kept in the presence of anterior-posterior balance spring
Metastable state, it will not be rocked with ship and produce collision with support 7.Locked cylinder 11 is in retracted mode, locks bearing pin 12
Also it is in retracted mode with oil cylinder 11.
When towage operating mode arm needs to shelve, arm 1 is slowly transferred, and rear cross beam 2 and the rear end of equalizer bar 6 of arm support
Point first contacts, and equalizer bar 6 is bounced back around the back rotation of hinge 8, rear balancing spring 4 under the Gravitative Loads of arm 1, forward horizontal stand bullet
Spring 5 extends, when equalizer bar 6 rotate to its elevation angle it is identical with arm 1 i.e. both are parallel when, the front beam 3 of arm 1 also with equalizer bar
6 front support points are contacted, and now arm 1 is held on equalizer bar 6, and buffering is provided between equalizer bar 6 and arm crossbeam 2,3
Rubber 13, effectively protection arm 1 and structure in the contact process of equalizer bar 6 are injury-free, and the balanced action of equalizer bar 6 makes four branch
The support force of support point is balanced；In above process, the locking otic placode 10 on arm crossbeam 2,3 also enters locking device 9 with putting down
Weigh beam 6 between, lock otic placode 10 on axis hole be slotted hole, it is ensured that with the axis hole of equalizer bar 6 and locking device 9 align into
Work(, now, locked cylinder 11 are acted, and bearing pin 12 is inserted among the axis hole on locking otic placode 10 and equalizer bar 6, completes locking,
Whole arm shelves process completion.
Crane needs to release arm when shelving, and for the inverse process shelved, locked cylinder 11 is acted, and bearing pin 12 is retracted,
Unlock, the raising of arm 1, slowly depart from equalizer bar 6, equalizer bar 6 anterior-posterior balance spring 4,5 effect under around hinge 8 to
Preceding rotation, until arm 1 completely disengages with equalizer bar 6, equalizer bar 6 returns to horizontal stable state, and arm 1 returns to the work elevation angle,
Shelve status releasing.
Specific embodiment described herein is only to the utility model spirit explanation for example.The utility model institute
Category those skilled in the art can make various modifications or supplement to described specific embodiment or using similar
Mode substitute, but without departing from spirit of the present utility model or surmount scope defined in appended claims.
