Abstract
The utility model relates to a lorry crane is with preventing slewer belongs to lorry crane technical field, partly takes place improper rot. Technical problem easily for solving to get on the bus at the driving in -process, according to the measuring and adjusting device, the structure is simple, high reliability, can effectively prevent the improper rot. Lorry crane is with preventing slewer of hoist in vehicle -mounted jack -up transportation vehicle driving process, the technical scheme who adopts sets up journal stirrup on the connection pad and the mounting panel of setting in the frame bottom the gyration stand for including, be provided with the through -hole on the journal stirrup, be provided with on the mounting panel and prevent the pivot cover, it sets up to prevent that pivot cover and through -hole are concentric, be provided with the stop pin axle in the through -hole, stop pin axle bottom cartridge is in preventing the pivot cover, stop pin crown of roll portion is provided with the handle, the utility model discloses the slewer who extensively is used for lorry crane.
Description
Technical field
The utility model relates to a kind of lorry-mounted crane anti-rotation device, belongs to lorry-mounted crane technical field.
Background technology
Lorry-mounted crane is that a kind of frame is loaded on automobile bottom jiggering, integrates the new and effective lifting transportation equipment of lifting, transport, is made up of, is connected respectively by bolt with the outer ring of pivoting support with inner ring upper frame part and lower frame part; Lower frame part is fixed on car chassis or dedicated platform and maintains static, and HM Hydraulic Motor full circle swinging mechanism drives pivoting support big gear wheel by HM Hydraulic Motor through drop-gear box, can realize the continuous rotary motion of upper frame part 360 °.
When driving, due to Uneven road or automobile starting, braking time the reason such as transient acceleration, can there is obvious swing in crane part (boom assembly, column assembly), reverse drive pivoting support turns round within the specific limits.Gyroscopic movement under this driving states, affects the stability of running car from safety aspect lecture, may cause some uncertain consequences; From affecting aspect to hoisting crane itself, the impact of moment can damage the faying face of gear pair, gently then adds the side clearance of gears meshing, causes revolution discontinuous, heavy then can badly influence the normal use of HM Hydraulic Motor and rotary reducer.
Utility model content
Easily there is improper pivotal technical matters in the upper frame part existed for solving prior art; it is simple that the utility model provides a kind of structure; reliability is high, effectively can prevent the improper pivotal lorry-mounted crane anti-rotation device of hoisting crane in truck with loading crane driving process.
For achieving the above object, the technical scheme that the utility model adopts is a kind of lorry-mounted crane anti-rotation device, comprise the journal stirrup be arranged on bottom rotary column on terminal pad and the adapter plate be arranged in frame, described journal stirrup is provided with through hole, adapter plate is provided with anti-rotation shaft sleeve, and described anti-rotation shaft sleeve is arranged with through hole is concentric, is provided with rotation prevention pin shaft in described through hole, be inserted into bottom rotation prevention pin shaft in anti-rotation shaft sleeve, rotation prevention pin shaft top is provided with handle.
Preferably, described handle is the U-shaped structure be made up of round steel.
Compared with prior art, the utility model has following technique effect: the utility model structure is simple, reliable operation, in driving conditions can by upper-part rotation part and lower frame part locked, prevent both occur improper gyroscopic movement, realize the requirement in latch functions; When using crane job, rotation prevention pin shaft is extracted the locking can removed upper-part rotation part.
In addition, handle is formed by round steel bending, and locking shaft is formed by the round steel machinework that is shaped, and has taken into full account the operational space of hand during design, is convenient to mention and instrumentation operations.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of lorry-mounted crane anti-rotation device, comprise the journal stirrup 1 be arranged on bottom rotary column on terminal pad and the adapter plate 2 be arranged in frame, journal stirrup 1 is provided with through hole 3, adapter plate 2 is provided with anti-rotation shaft sleeve 4, described anti-rotation shaft sleeve 4 is arranged with through hole 3 is concentric, is provided with rotation prevention pin shaft 5 in described through hole 3, be inserted in anti-rotation shaft sleeve 4 bottom rotation prevention pin shaft 5, rotation prevention pin shaft 5 top is provided with handle 6.Journal stirrup 1 can be welded on column bottom terminal pad, and also can be designed to integral type with terminal pad, direct blanking forms; Anti-rotation shaft sleeve 4 selects welding solid drawn pipe regular size, adds without the need to machine, is directly welded on frame upper mounting plate 2.When driving can by upper-part rotation part and lower frame part locked, prevent both occur improper gyroscopic movement, realize the requirement in latch functions; When using crane job, rotation prevention pin shaft is extracted the locking can removed upper-part rotation part.
In addition, handle 6 is the U-shaped structures be made up of round steel, has taken into full account the operational space of hand, is convenient to mention and instrumentation operations.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should wrap within the scope of the utility model.
