Abstract
The utility model discloses an upper limiting protection device for a miniature steel wire rope electric block. The upper limiting protection device comprises a housing (1), a motor and transmission mechanism (2), a steel wire rope reel, an upper limiter (3), a steel wire rope (4), a limiting block (5) and a lifting hook (9), wherein the upper limiter (3) is arranged on the motor and transmission mechanism (2); the steel wire rope (4) is wound on the steel wire rope reel; the steel wire rope (4) is fixedly connected with the lifting hook (9) after passing through the upper limiter (3) and the limiting block (5); a spring (6) and a spring washer (7) are arranged on the steel wire rope (4) below the limiting block (5) and are connected together; the upper end of the spring (6) is abutted against the limiting block (5); and the bore diameter of the spring washer (7) is less than the diameter of a steel wire rope fastener (8). After the structure is adopted, the upper limiting protection device has the advantages of simple and reasonable structure, good impact resistance, safe and reliable hoisting, good stability and the like.
Description
Technical field
The utility model relates to a kind of miniature steel-wire rope type electric block, the upper limit buffer protection device that uses on particularly a kind of miniature steel-wire rope type electric block.
Background technology
Recovery along with global economy; People hope the miniature steel-wire rope type electric block of being purchased more can be value-for-money; Existing miniature steel-wire rope type electric block on the market comprises case, motor and transmission device, cable drum, upper limit device, steel rope, limiting stopper, suspension hook, and the upper limit device is arranged on motor and the transmission device; Wire rope roll is on cable drum, and steel wire penetrating upper limit device, limiting stopper are also captiveed joint with suspension hook through wire line hitch.Can promote the goods below 1000 kilograms, be specially adapted to high-rise building downstairs from the heavier article of slinging.Simple in structure, easy for installation, small and exquisite, and with unidirectional electrical as propulsion source.
When single hook block was heavy, the limiting stopper below directly was a wire line hitch, impacted greatlyyer when causing upper limit like this, can cause the distortion of upper limit device up to losing function after repeatedly impacting.When the double hook lift heavy, the pulley suspension hook directly removes top upper limit device, rather than limiting stopper top upper limit device, the weak point of its existence: the one, impact bigger; The 2nd, because the angle problem can cause the pulley suspension hook stuck by wire line hitch, thereby forfeiture upper limit function becomes tiltedly the weight that hangs, and the danger of dropping is arranged, and makes originally for avoiding maloperation design-calculated upper limit device to fail to give full play to its due effect.To the problems referred to above, many manufacturers and knowledgeable people constantly develop and study, but comparatively ideal steel-wire rope type electric block upper limit fender guard is not arranged so far as yet; Therefore, develop a kind of convenience simple in structure, safe and practical miniature steel-wire rope type electric block upper limit buffer protection device is extremely urgent problem.
Summary of the invention
For overcoming the above-mentioned deficiency that existing miniature steel-wire rope type electric block exists, the purpose of the utility model provides a kind of simple and reasonable, shock resistance, safe miniature steel-wire rope type electric block upper limit fender guard.
The utility model solves the technical scheme that its technical matters adopted; It comprises case, motor and transmission device, cable drum, upper limit device, steel rope, limiting stopper, suspension hook; The upper limit device is arranged on motor and the transmission device, and wire rope roll is on cable drum, and steel wire penetrating upper limit device, limiting stopper are also captiveed joint with suspension hook through wire line hitch; The steel rope of said limiting stopper below is provided with spring and spring shim; Spring and spring shim link together, and the spring upper end withstands on the limiting stopper, and the aperture of spring shim is less than the diameter of wire line hitch.
Light in order to move up and down, fluent, described limiting stopper, spring and spring shim can be enclosed within on the steel rope up and downly.
When the double hook lift heavy, described suspension hook is fixed on the case, and movable sleeve is provided with the pulley suspension hook on the steel rope of spring shim below.
After adopting said structure, and following advantage of prior art and effect: the one, can be as required arbitrarily dismounting and installing simply, easily, both can single hook block heavy, but double hook lift heavy again; The 2nd, project organization is reasonable, and is sturdy and durable; The 3rd, the upper limit device receives the effect of spring buffer, can significantly reduce impulsive force, effectively improves impact resistance; The 4th, play the shock resistance effect by limiting stopper top upper limit device, spring when guaranteeing upper limit all the time; The 5th, stable installation property is good, uses more safe and reliable.
Description of drawings
Fig. 1 is the heavy structural representation of the utility model list hook block.
Fig. 2 is the structural representation of the utility model double hook lift heavy.
1 case wherein, 2 motors and transmission device, 3 upper limit devices, 4 steel ropes, 5 limiting stoppers, 6 springs, 7 spring shims, 8 wire line hitchs, 9 suspension hooks, 10 pulley suspension hooks.
The specific embodiment
Shown in Figure 1; Be the heavy specific embodiments of the miniature steel-wire rope type electric block upper limit of the utility model fender guard list hook block, it comprises case 1, motor and transmission device 2, cable drum, upper limit device 3, steel rope 4, limiting stopper 5, suspension hook 9, and upper limit device 3 is arranged on motor and the transmission device 2; Steel rope 4 is wound on the cable drum; Steel rope 4 passes upper limit device 3, limiting stopper 5 and passes through wire line hitch 8 captives joint with suspension hook 9, and the steel rope 4 of said limiting stopper 5 belows is provided with spring 6 and spring shim 7, and spring 6 is fixed together with spring shim 7; Spring 6 upper ends withstand on the limiting stopper 5; Limiting stopper 5, spring 6 and spring shim 7 can be enclosed within on the steel rope 4 up and downly, and the aperture of spring shim 7 is less than the diameter of wire line hitch 8, and spring shim 7 leans against on the wire line hitch 8.
Shown in Figure 2; Be the specific embodiments of the miniature steel-wire rope type electric block upper limit of the utility model fender guard double hook lift heavy, the specific embodiments difference heavy with single hook block is: described suspension hook 9 barbs are on case 1, and pulley suspension hook 10 is slidingly connected on the steel rope 4 between spring shim 7 and the wire line hitch 8; In the lift heavy process, can remove top upper limit device by limiting stopper 5 all the time; Under spring 6 effects, can better cushion the impulsive force of lift heavy, strong shock resistance.
