Abstract
The utility model relates to an integrated lifting weight stopper which matches with a bridge crane and an electric hoist, which comprises an electric control instrument and a weighting sensor. The weighting sensor and the electric control instrument are integrally connected, in which the lines are connected. A fixed block is arranged under the weighting sensor. A pressing block is arranged in the middle of the lower part of the weighting sensor and a bolt which connects with a screw thread is opened under the pressing block. The fixed block is provided with a self-locking protector. The utility model has the advantages: the integrated lifting weight stopper is arranged on a wire rope at one end of a pulley equalizer of a portal crane or an electric hoist, has the advantages of compact structure, flexible operation and convenient adjustment; prevents the overload running and the hidden danger when lifting the heavy object, eliminates the overloading case, realizes the safe operation when lifting, improves the reliability and the security of the work, and solves the problem of overloading and hidden danger of the lifting equipment in the prior art.
Description
Technical field
The utility model relates to a kind of and crane in bridge type, the supporting integrated load lifting limiter of electric block, belongs to crane safety device technique field.
Background technology
Weight-lifting equipment such as crane in bridge type, electric block belongs to the special equipment scope, in use presses code requirement, does not allow the hoisting heavy that overloads.But in daily production process, because operator's carelessness or awareness of safety are not enough, use weight-lifting equipment overload phenomenon of common occurrence, many safety misadventures took place, loss is comparatively heavy.National Quality Supervision Bureau General provides notice specially for this reason, and what require on April 1st, 2009 to rise to dispatch from the factory must all be provided with load lifting limiter and overcurrent (overload) fender guard.At present, the load lifting limiter that occurs on the market is confined to sensor and two monomers of control instrument are fixed together, between by cable connection, between connecting cable produced fault by collision easily.Control circuit generally adopts traditional discrete component, manual adjustment, and poor stability, precision is low.Itself does not have fender guard load lifting limiter, in case installation or use are owing to reasons such as bolt looseness directly produce accident from falling down in the air.Prevent overload in order effectively to control hoisting capacity, reduce safety misadventure, take a kind of simple in structure; easy for installation; itself has safety protection function by oneself, can adapt under the various conditions and work, and safe and effective restriction weight-lifting equipment overload is the action of being eager to need to solve.
Summary of the invention
Design goal: avoid the weak point in the background technology, design and a kind ofly can solve bridge-type gantry crane in the prior art, electric block operation overload effectively and jeopardize safe integrated load lifting limiter.
Design plan: in order to realize above-mentioned design goal.The utility model is on structure design, and integrated load lifting limiter is synthesized together electrical control instrument and LOAD CELLS, and internal wiring connects, and can not break.The electrical control instrument adopts AD to transform micro controller system, by software programming control, good stability, precision height, strong anti-interference performance.Acoustic control (buzzer phone) and indicator lamp are reported to the police and are adopted parallel way, have solved tradition: acoustic control and indicator lamp series system, and when the problem of all can not reporting to the police of two of side's faults wherein.Integrated load lifting limiter increases self-locking protecting device, and steel wire penetrating self-locking protecting device during installation can be along the steel rope landing when integrated load lifting limiter drops, and can not influence ground staff and device security from directly falling in the air.Can effectively solve the inherently safe problem.
Technical scheme: integrated load lifting limiter; it comprises electrical control instrument and LOAD CELLS; the LOAD CELLS below is equipped with fixed block; briquetting is positioned in the middle of the LOAD CELLS below and the briquetting below has the bolted connection screw thread; LOAD CELLS and electrical control instrument be connected as a single entity and connection line built-in, install self-locking protecting device on the fixed block additional.
The utility model is compared with background technology, integrated load lifting limiter is contained on the steel rope of gantry crane or electric block equalizer pulley device one end, compact conformation not only, flexible operation, easy to adjust, and super negative operation and inherently safe hidden danger when having limited hoisting heavy, stopped the generation of overload situation, realized the lifting safe in operation, improved the reliability and the safety of work, solved in the prior art weight-lifting equipment overload and jeopardized safe problem.
Description of drawings
Fig. 1 is the structural representation of integrated load lifting limiter.
The specific embodiment
Embodiment 1: with reference to accompanying drawing 1.Integrated load lifting limiter, it comprises electrical control instrument 1 and LOAD CELLS 3, LOAD CELLS 3 belows are equipped with fixed block 4, briquetting 7 is positioned in the middle of LOAD CELLS 3 belows and briquetting 7 belows have bolted connection screw thread 8, LOAD CELLS 3 and electrical control instrument 1 be connected as a single entity and connection line built-in, the electrical control instrument adopts AD to transform micro controller system, embedded software programming Control.Electrical control instrument 1 is provided with buzzer 2 and warning indicator lamp, and acoustic control and indicator lamp are reported to the police and adopted parallel way.Install self-locking protecting device 6 on the fixed block 4 additional; described self-locking protecting device 6 connects and composes the ring of remaining silent for slotted ring and with fixed block 4; this fixed block 4 can be one or two; in the time of two, lay respectively at the left and right sides of LOAD CELLS 3 lower surfaces, promptly be spacing and distribute; steel wire penetrating self-locking device when purpose is installed; can be when integrated load lifting limiter drops along the steel rope landing, and can not influence ground staff's safety in the air from directly falling.
When the weight-lifting equipment hoisting heavy, steel rope is stressed, LOAD CELLS 3 outputs signal to electrical control instrument 1, be transformed into micro controller system through A/D, judge whether overload by the design-calculated special software, if surpass specified weight, buzzer 2 and indicator lamp in the integrated load lifting limiter are reported to the police simultaneously, cut off the electricity supply when surpassing 105%.
Need understand and be: though the foregoing description is to the mentality of designing of the present utility model detailed text description of contrasting; but these text descriptions; just the simple text of the utility model mentality of designing is described; rather than to the restriction of the utility model mentality of designing; any combination, increase or modification that does not exceed the utility model mentality of designing all falls in the protection domain of the present utility model.
