Abstract
The utility model discloses the type cantilever device that a kind of balance weight stepless is adjustable, comprise counterweight, support and cantilever, described cantilever is installed and is hinged on support, counterweight is fixed on the tail end of cantilever, described counterweight comprises casing and weight material, the bottom of described casing and top are respectively equipped with discharge gate and pan feeding door closure, and described weight material is seated in casing.The utility model makes full use of the low weight material of price, reaches and reduces costs; Version reasonable in design, need not be prefabricated, reduces monolithic weight, reaches and reduce the differential object of weight; Limestone, slag and recovery ball grinding mill discard abrasive body (steel forging, steel ball) as weight material, and cost of material is more cheap, and it is convenient to obtain.
Description
Technical field
The utility model belongs to mainly a kind of type cantilever device that arbitrarily can regulate balance weight.
Background technology
The type cantilever device such as hoisting crane, cantilever stacker-reclaimer, all utilize lever principle design, increment load, the other end just needs to mate corresponding clump weight, guarantees the balance at fulcrum place, to prevent equipment center of gravity overbalance, even topples.
Present stage, type cantilever device counterweight mainly used cast iron prefabricated section or cement block as counterweight.The advantage that cast iron prefabricated section does counterweight is that volume is little, and than great, shortcoming is that price is high, and monolithic weight is large, and adjustment is inconvenient.What truck mounted boom crane was conventional is cast iron prefabricated section, and hangs or be fixed on the rotating disk of cantilever, joins the block number of extension, but can not adjust the substance of clump weight according to how many changes of hoisting heavy.Cement block does counterweight, and to compare casting pig price low, and shortcoming remains that monolithic weight is large, and regulating weight is greatly differential, and adjustment is inconvenient.What cantilever stacker-reclaimer was conventional is exactly cement block, and is suspended on equipment supporter, determines clump weight number according to cantilevered weights etc.But because cement block substance is comparatively large, regulating weight is greatly differential, always causes equipment to have certain overbalance, causes column or equipment bogie wheel pressure imbalance.
Present principal contradiction can use price low exactly, and monolithic weight is little, and regulating weight is differential little, need not be prefabricated, and Weighting system easy to adjust guarantees the balance of equipment to greatest extent.。
Summary of the invention
Goal of the invention: for above-mentioned existing Problems existing and deficiency, the purpose of this utility model there is provided the adjustable type cantilever device of a kind of balance weight stepless, can prevent the fault of toppling that equipment unbalance stress causes.
Technical scheme: for achieving the above object, the utility model is by the following technical solutions: the type cantilever device that a kind of balance weight stepless is adjustable, comprise counterweight, support and cantilever, described cantilever is installed and is hinged on support, counterweight is fixed on the tail end of cantilever, described counterweight comprises casing and weight material, and the bottom of described casing and top are respectively equipped with discharge gate and pan feeding door closure, and described weight material is seated in casing.
As preferably, the outer wall of described casing is provided with multi-turn reinforced rib.
As preferably, the bottom of described support is provided with front-wheel and trailing wheel.
Described weight material selects the loose shape particles such as the forging of limestone, slag, steel or steel ball, thus can change the weight material of higher or lower unit weight at any time, and can load arbitrarily and gush casing, reaches the step-less adjustment of weight.
Beneficial effect: compared with prior art, the utility model has the following advantages: make full use of the weight material that price is low, reach and reduce costs; Version reasonable in design, need not be prefabricated, reduces monolithic weight, reaches and reduce the differential object of weight; Reclaim ball grinding mill and discard abrasive body (steel forging, steel ball) as weight material, cost of material is more cheap, and it is convenient to obtain.
Accompanying drawing explanation
Fig. 1 is the structural representation of type cantilever device described in the utility model;
Fig. 2 is the structural representation of counterweight described in the utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, these embodiments should be understood and be only not used in restriction scope of the present utility model for illustration of the utility model, after having read the utility model, the amendment of those skilled in the art to the various equivalent form of value of the present utility model has all fallen within the application's claims limited range.
As illustrated in fig. 1 and 2, chief component of the present utility model: type cantilever device is generally made up of counterweight 1, trailing wheel 2, support 3, front-wheel 4 and cantilever 5.Support 3 is arranged on front-wheel 4 and trailing wheel 2, and cantilever 5 is arranged on support 3, and counterweight 1 is arranged on the tail end of cantilever 5.Counterweight in the utility model is made up of pan feeding door closure 6, weight box 7, weight material 8 and discharge gate 9.Weight box 7 is provided with feeding mouth 7-1, casing 7-2, reinforced rib 7-3 and discharge port 7-4.Weight material 8 loads in weight box 7 from feeding mouth 7-1, also can draw off from weight box 7 through discharge gate 9.Counterweight casing 7-2 outer setting has reinforced rib 7-3, prevents casing 7-2 stress deformation after the more weight material 8 of interpolation.
Principle of work: type cantilever device counterweight principle: counterweight 1 is arranged on the afterbody of cantilever 5, passes to cantilever 5 by power.Cantilever 5 is bearing on support 3.Because cantilever 5 front portion is longer, and heavier-weight, cantilever 5 afterbody is shorter, and lighter in weight, therefore need to use counterweight 1 to make cantilever reach state of equilibrium relative to support 3.Equipment and balance weight are passed to guide rail or ground through front-wheel 4 and trailing wheel 2 by support 3.
If cantilever 5 balances relative to support 3, then the pressure that bears of front-wheel 4 and trailing wheel 2 is close to equal, if counterweight overbalance, then not there will be two-wheeled wheel load not etc., just likely damage is caused to wheel or basis, serious even topples, and therefore just needs increase or reduce balance weight, in the hope of reaching balance.
Be added into until balance in casing 7-2 through feeding mouth 7-1, if counterweight is not enough, then continue to add; If overweight, then open discharge gate 9, draw off part weight material 8, until balance.If the weight material of the low unit weight added cannot meet the demands, then weight material is drawn off completely, be replaced by the weight material of higher unit weight, such as steel forging.
Weight material 8 is bulk material, conveniently adds and draws off, and can reach step-less adjustment, makes stressedly to reach balance.
After weight material has been added, pan feeding door closure 6 is arranged on feeding mouth 7-1, has fallen when avoiding someone to overhaul.
