Abstract
The utility model discloses a crane lifting device and relates to an industrial device. The crane lifting device comprises an electric block, a lifting hook connected with the electric block through a steel wire rope, driving traveling motors, traveling gears and a crane cross beam. The electric block is provided with non-contact limiting stoppers. The surfaces of the electric block, the lifting hook, the driving traveling motors, the traveling gears and the crane cross beam are respectively provided with a glass fiber reinforced plastics erosion resistant coating. The non-contact limiting stoppers can control height of the lifting hook of the crane by sensing without contacting, and has the advantages of being sensitive in response, free of impacting, capable of adapting to hostile outdoor environment, good in economical efficiency and practical. By means of the non-contact limiting stoppers, maintenance cost is reduced, and labor and production efficiency is improved.
Description
Technical field
The utility model relates to a kind of commercial unit, relates in particular to a kind of crane lifting device.
Background technology
At present, the hoisting crane elevation is spacing generally to adopt mechanical contact formula element control elevation, is met and discussed by body, connecting rod and rolling as the one of which and forms, and internal body has extension spring, contact, connection terminal.On the end position at the large and small car orbit of hoisting crane two ends, travel switch is installed, and is being gone up installation collision block (travel switch and collision block also can be opposite installation sites) with the movable parts (large and small car) of its relative motion.Above-mentioned mechanical contact formula element reaction lags behind, has bump, and fragile behind long-play, needs often maintenance and replacing; Waste manpower and materials, and in use possibly cause load hook spacing malfunctioning for above-mentioned reasons, caused hoisting crane to damage thus; Thereby safety misadventure possibly take place; Brought very big potential safety hazard in use, and after hoisting crane was damaged, maintenance cost was high.
Summary of the invention
To the problem that above-mentioned prior art exists, the utility model provides a kind of crane lifting device, and its inhibiting device need not contact and only promptly can control the crane hook height through induction; Be quick on the draw, do not have bump, can adapt to abominable outdoor environment; Better economy; And reduced the Maintenance and Repair cost, and improved labor productivity, very practical.
The technical scheme of the utility model is: a kind of crane lifting device, and comprise electric block, pass through steel rope and electric block bonded assembly suspension hook, drive movable motor, walking gear and hoisting crane crossbeam, said electric block is provided with the no touch limiting device; Electric block, suspension hook, driving movable motor, walking gear and hoisting crane beam surface are respectively arranged with the glass-felt plastic preservative coat.
As preferably, said no touch limiting device is the waterproof type inductance approach switch.
As preferably, said no touch limiting device is 2.
The beneficial effect of the utility model is: the utility model adopts the no touch limiting device to substitute the mechanical contact formula element of original lift system; It need not contact and only promptly can control the crane hook height to prevent that the suspension hook superelevation from causing the heavy-duty machine lift system to damage and causing safety misadventure through induction; When suspension hook is about to superelevation; Can cut off the electricity supply through electromagnetic induction, stop suspension hook and rise, reach the spacing purpose of suspension hook.Adopt the waterproof type inductance approach switch, can adapt to abominable outdoor environment.Adopt two no touch limiting devices simultaneously, when one malfunctioning after, another no touch limiting device can continue normal operation, has guaranteed the safety and the operating cycles of hoisting crane, has reduced and safeguard to have detected cost.The utility model can directly improve on existing hoisting crane, better economy, and reduce the Maintenance and Repair cost, improved labor productivity.Glass-felt plastic is good anticorrosion-rust prevention material; Atmosphere, water and multiple acid, alkali, salt and multiple organic solvent are all had good resistivity, prolonged the service life of the utility model, and it only needs at corresponding component external coating glass-felt plastic; Manufacture craft is simple, and is very practical.
Description of drawings
Fig. 1 is the front view of the utility model;
Fig. 2 is the lateral plan of the utility model.
The specific embodiment
A kind of embodiment as the utility model; As depicted in figs. 1 and 2;. a kind of crane lifting device; Comprise electric block 2, through steel rope and electric block 2 bonded assembly suspension hooks 3, driving movable motor 4, walking gear 5 and hoisting crane crossbeam 6, said electric block 2 is provided with no touch limiting device 1.In the present embodiment, as preferably, said no touch limiting device 1 is the waterproof type inductance approach switch, can adapt to abominable outdoor environment.Said no touch limiting device 1 is 2, when one malfunctioning after, another no touch limiting device 1 can continue normal operation, has guaranteed the safety and the operating cycles of hoisting crane, has reduced and safeguard to have detected cost.Electric block 2, suspension hook 3, driving movable motor 4, walking gear 5 and hoisting crane crossbeam 6 surfaces are respectively arranged with the glass-felt plastic preservative coat.Glass-felt plastic is good anticorrosion-rust prevention material; Atmosphere, water and multiple acid, alkali, salt and multiple organic solvent are all had good resistivity, prolonged the service life of the utility model, and it only needs at corresponding component external coating glass-felt plastic; Manufacture craft is simple, and is very practical.
The above is merely a kind of embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and obvious mode of texturing etc., all should be included within the protection domain of the utility model.
