Description
Technical field
Adjusted automatically for single-cantilever-crane gantry crane counterweight the present invention relates to gantry crane technical field, especially one kind
Nodule structure.
Background technology
Single-cantilever-crane gantry crane, the fully loaded probability used of particularly large-scale single-cantilever-crane gantry crane is less, uses
Grade is low, if be designed according to fixed counterweight, and single-cantilever-crane gantry crane is in underloading or off working state, revolution branch
Support is all the time by the larger bending load of fixed weight, and particularly in off working state, stress point position is constant all the time so that
Complete machine structure is in unfavorable loaded state all the time by fulcrum of revolving support.Fixed counterweight typically has two kinds of mounting means,
It is a kind of be it is a small amount of be mounted directly with focusing on ground, together with rotating disk above integral hoisting after installation, be suitable for less list
Arm support gantry crane, it is another that to be substantial amounts of counterweight installed by the crane when limiting, it is necessary to after rotating disk is installed in place,
High-altitude is installed by other means, is generally suitable for large-scale single-cantilever-crane gantry crane.
The problem of counterbalance design of prior art and installation are present be：The general total cost in order to control gate seat machine, will not
Steel is selected as counterweight, but the relatively low concrete of selection density or concrete aggregate, as counterweight, this can cause gantry crane
Computer room tail radius it is big, tail clearance is highly low, installation difficulty, dangerous higher, and large-scale gantry crane from it is great,
Center of gravity is high, and in off working state, center of gravity is substantially at eccentric state so that the less stable of whole machine, to foundation of civil work
Track, grappling and anchor requirement for bearing capacity are also high so that civil engineering makes that basic high price is expensive, have a strong impact on the use peace of crane
Full property and economy.
The content of the invention
A kind of single-cantilever-crane gantry crane counterweight that the purpose of the present invention is in view of the shortcomings of the prior art and designed is automatic
Adjustment structure, using the mobile counterweight mechanism being arranged on below rotating disk, the front and rear equalising torque of progress counterweight and sling load is certainly
Dynamic regulation, realizes equalising torque of the complete machine structure using revolving support as fulcrum, and single-cantilever-crane gantry crane is in off working state
When, the angle of arm support and balance position equalising torque matching be can be subjected to, the horizontal centre and vertical center weight of crane made
Close, it is to avoid produce excessive wheel load, and rotating disk produces larger centrifugal force when rotating with the wind, it is simple and reasonable for structure so as to return
Turn supporting in whole circle uniform-compression state, reduce revolving support bearing requirements, make mechanical structure lighter, material usage is more
About, revolving support selects less diameter to supernumerary segment, and the decline of main screw lift directly causes the decline of crane wheel load, so that right
Running track, grappling and the requirement of anchor foundation are substantially reduced, and maintenance of equipment is convenient, further reduction foundation of civil work cost and peace
Dress expense so that the cost of equipment in itself declines to a great extent.
The object of the present invention is achieved like this：A kind of single-cantilever-crane gantry crane counterweight self-regulation structure, its feature
It is that the rotating disk of single-cantilever-crane gantry crane has the movement of ballast box and counterweight traction drive and slideway or track composition
Balance weight mechanism carries out automatically adjusting for counterweight and sling load, and the slideway or track are arranged under rotating disk and are weldering with rotating disk
Connect；The ballast box is suspended under slideway or track and is connected with counterweight traction drive, and counterweight traction drive is automatic
Shift position of the ballast box under slideway or track is adjusted, the equalising torque using revolving support as the complete machine structure of fulcrum is realized.
The counterweight traction drive be rope traction driving, hydraulically extensible hydraulic oil cylinder driving, leading screw traction drive or
Driving chain traction drive.
The slideway or track are two and are symmetrical arranged.
The present invention has simple in construction, revolving support selection less diameter compared with prior art, makes mechanical structure more
Light, material usage is more saved, the decline of main screw lift, directly causes the decline of crane wheel load, thus to running track,
Grappling and the requirement of anchor foundation are substantially reduced, and maintenance of equipment is convenient, reduction foundation of civil work cost and mounting cost so that equipment
The cost of itself declines to a great extent, and further improves security and economy that crane is used.
