Description
Technical field
The present invention relates to tower crane equipment technical field, more particularly to a kind of tower crane device for preventing lifting rope from winding.
Background technology
Tower crane is a kind of crane gear also known as " derrick crane " the most frequently used on construction site, with a section spreading
(height) (referred to as " standard knot "), for hanging the raw material of the constructions such as working reinforcing bar, wood stupefied, concrete, steel pipe.Tower crane is work
A kind of essential equipment on the ground.The function of tower crane point is subject to the upper load that arm support drawstring and counter-jib drawstring transmit,
And the structure member formula by turning round pylon, turntable, bearing etc. directly passes to tower body structure by turntable.Have from a liter tower top and cut
Cone pillar, lean forward or hypsokinesis truncated cone pillar, herringbone posture and diagonal brace posture.Every upper rotary tower crane is both needed to set balance weight, its work(
Can be supporting balance weight, to effect aspect and hoisting moment trimming moment in opposite direction required on Construction designing.Remove
Outside balance weight, lifting mechanism often also is installed in its afterbody, why homostasis weight is placed in counter-jib tail end to lifting mechanism together,
First part counterweight effect can be played, second increase the distance between rope reel and pinnacle of a pagoda guide wheel, with the row of sharp steel wire rope around and keep away
Exempt from that disorder cable phenomenon occurs, the dosage of balance weight and the length of counter-jib inversely, and balance arm lengths and jib length
Between again certain proportion relation be present.Counterpoise is considerable, and light-duty tower crane typically at least wants 3 to arrive 4t, and heavy is near
30t。
But existing building tower crane device, in use there is in place of some shortcomings, the cotton rope of tower crane is frequent
The phenomenon being intertwined occurs, user operates the cumbersome of change when lifting by crane article.
The content of the invention
The invention aims to solve shortcoming present in prior art, and a kind of of proposition prevents what lifting rope from winding
Tower crane device.
To achieve these goals, present invention employs following technical scheme：A kind of tower crane device for preventing lifting rope from winding,
Including limited support bar, fixing pipe and fixed seat, be welded with rope gland at the top of the fixed seat, the fixed seat it is interior
Portion is provided with MYT3-23 hydraulic drivers, and the bottom of the fixed seat is connected with buffer protection layer by adjustable spring, described solid
The both sides of reservation are symmetrically welded with fixing pipe, and the side of the fixing pipe is connected by fixing bolt with connecting rod, the connection
Limiting plate is welded with the port of bar.
As further describing for above-mentioned technical proposal：
The fixing pipe positioned at the same side is welded with limited support bar between any two.
As further describing for above-mentioned technical proposal：
The expansion link being connected with the MYT3-23 hydraulic drivers inside fixing pipe, and at the port of expansion link
Pulley is connected with by rotary shaft.
As further describing for above-mentioned technical proposal：
Spacing between the pulley and limiting plate is 4CM.
As further describing for above-mentioned technical proposal：
Limited location smooth plate is set between the thin bar in the fixing pipe and expansion link.
As further describing for above-mentioned technical proposal：
The MYT3-23 hydraulic drivers input is electrically connected with controller output end in control room.
As further describing for above-mentioned technical proposal：
Level inclination between the fixing pipe and fixed seat is 30 degree.
In the present invention, fixing pipe is provided with the both sides of fixed seat first, fixing pipe is internally provided with expansion link, and
The pulley and limiting plate for limiting lifting rope position are welded with the port of expansion link, when the lifting rope on tower crane is operated,
The position of lifting rope can be limited by the device, prevents lifting rope to be intertwined, it is more convenient that user is operated, and secondly this is flexible
Bar can adjust the position of lifting rope, more preferable for the position limitation effect of cotton rope, finally pass through the bullet that stretches in the bottom of fixed seat
Spring and buffer protection layer, when the fixed seat falls, can carry out buffer protection to it, avoid dangerous generation.
