Description
Technical field
The utility model relates to hoisting crane accessory equipment, particularly the straight measuring moment device of a kind of tower crane.
Background technology
At present, cognitive measurement tower crane moment is mechanical type bow plate tension ring, under moment loading, is out of shape, and touches mechanical switch, thereby reaches the object of protection tower crane.Because the performance of metallic material cannot quantize to play heavy object to tower crane with accurate response; Also having one is to measure loads weight, and measurement loads is to vertical distance---the arm of force of the position of tower crane fulcrum, calculate the moment to hoisting crane through mathematical operation again, but the coder of measuring the arm of force expands because the inertia of crane rope makes range error, do not ensure that tower machine uses safety, can not meet the needs of real work.
Summary of the invention
For above-mentioned situation, for overcoming the defect of prior art, the object of the utility model is just to provide the straight measuring moment device of a kind of tower crane, and can effectively solve tower crane moment cannot quantize, and misses by a mile, and has the problem of potential safety hazard.
The utility model solve technical scheme be, comprise elastomer sensor and locating piece, elastomer sensor is fixed on through locating piece on the chord member of tower crane, and strain-gauge is housed on elastomer sensor, strain-gauge is connected with controller through wire.
The utility model novel structure uniqueness, advantages of simple, easily produces, and easy to operate, take off data is accurate, not fragile, and long service life is safe and reliable, easy to use, effective, is the innovation on tower heavy-duty machine accessory equipment.
Brief description of the drawings
Fig. 1 is front view of the present utility model.
Fig. 2 is the front view of the utility model elastomer sensor.
Fig. 3 is the left view of the utility model elastomer sensor.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
Provided by Fig. 1-3, the utility model comprises elastomer sensor and locating piece, and elastomer sensor 1 is fixed on the chord member 6 of tower crane 9 through locating piece 3, and strain-gauge 2 is housed on elastomer sensor 1, and strain-gauge 2 is connected with controller 7 through wire 4.
For ensureing result of use, described locating piece 3 is fixed on elastomer sensor 1 back side through bolt 5, and locating piece 3 can directly be welded on the chord member 6 of tower crane 9, is closely connected as a single entity with chord member;
Threading sleeve pipe 10 for fixing cord is housed, with guardwire on described elastomer sensor 1;
Described bolt 5 is high strength bolt;
Described controller 7 is that the patent No. of applicant's earlier application is " a kind of Novel overload protection control box of electric hoist " of " 200920091247.3 ";
Described elastomer sensor 1 is commercially available prod (known technology), can receive the deformation from chord member, this deformation is passed to strain-gauge 2 simultaneously, as the sensor S type elastic body of Yin Zhou Aide hardware machinery Co., Ltd of Ningbo City production and selling, and for example LOAD CELLS, the elastic body of square field, Shanghai elastic body Co., Ltd production and selling etc. of the three-dimensional Electric Manufacture of Yixing City Co., Ltd production and selling; On elastomer sensor 1, open bolt hole, bolt 5 is fixed together by bolt hole and knock hole, and locating piece is welded on chord member again, forms the conducting structure of deformation.
Service condition of the present utility model is; when load-carrying object drives chord member 6 deformation that bends by the pull bar 8 of tower crane; strain-gauge 2 on elastomer sensor 1 converts the mechanical energy of this deformation to electric signal output; this electric signal and loads position are linear to the vertical length (arm of force) of jib fulcrum; can be on controller the direct moment of loading display thing to tower crane effect, work thereby reach protection jib the object that focuses on normal work in specified scope of design.When use, controller can be contained in operator's compartment, to facilitate chaufeur observation and operation, compared with prior art; the utility model novel structure uniqueness, advantages of simple, easily produces; easy to operate, directly perceived, moment that can direct-detection tower crane; and automatic early-warning, warning, protection hoisting crane is worked in normal range, and take off data is accurate; not fragile, long service life, safe and reliable; easy to use, effective, there are good society and economic benefit.
