Abstract
The utility model relates to a portable cramp hoist, which is a minitype electromechanical hoisting device. The utility model is composed of a cramp hanger and an electric part, wherein, the cramp hanger comprises a clamp and a suspender which is formed in a way that a crank arm and a straight arm are hinged with each together, the clamp is composed of a fixed frame, a sleeve, a flexible clamp plate, a diagonal supporting rod, a winch, a screw rod and a fixed screw cap, and the electric part is a column-shaped assembly formed by a motor, a winch barrel, and a power-off wheel frame brake system. The utility model has the advantages of simple structure, convenient installation, big hoisting strength and reliable operation and is a multipurpose portable hoisting tool.
Description
The utility model is the light lifting machine of a kind of fixture type, belongs to small-sized dynamo-electric lifting means.
Existing engineering lifting means adopts crane, winch more, and the simplest artificial pulley of employing or dead man are also arranged.The JK02 light-weight electric winch close with the utility model, have following problem: 1, the fixed form of this machine employing is " Jackstay type ", what its support fixedly leaned on is " the support power " of a Metallic rod, " support power " upwards is contrary to the stressed hypothesis of upper plate, the firm elasticity of strut is located owing to reasons such as squareness are inaccurate at " support node ", be easy to generate and mould hinge " activity ", poor safety performance; 2, this machine must dispose different suspension brackets in different use occasions, and must two people could install; 3, traditional arbor brake is partly adopted in the braking of this machine, and lock torque is little, and retro-speed is slow relatively; 4, the motor of this machine, suspension hook and cantilever have strengthened suspension hook capsizing moment on one side with setting aside.
The utility model is intended to provide a kind of the laborsaving, convenient, safe and reliable of small-sized object vertical transport and lightly small-sized efficiently dynamo-electric lifting means of being used for for industries such as buildings.
The light lifting machine of the fixture type that the utility model provides is made up of fixture type suspension bracket (1) and electronic part (2).Fixture type suspension bracket (1) partly is made up of anchor clamps (3) and suspension rod (4) two, anchor clamps (3) are by fixed mount (5), sleeve (6), clamping plate (7) alive, hound (8), capstan winch (9), screw rod (10), hold-doun nut (11) is formed, fixed mount (5) is made up of two groups of hinged chan frames, the bottom of sleeve (6) is a square floor (12), one side of base plate (12) is hingedly fixed on the cruciform bracing of fixed mount (5), another side is fastening by screw rod and nut, the tube internal upper part of sleeve (6) is equipped with a vertical bearing that is provided with, and the bottom also is provided with the bearing of a horizontal force in the tube of sleeve (6).The two ends of hound (8) use bolted splice respectively on live clamping plate (7) and fixed mount (5), one group of chan frame of living clamping plate (7) and the fixed mount (5) of sleeve (6) being housed all has a drag hook and a screw that mates with capstan winch (9) screw rod (10), hold-doun nut (11) also mates with capstan winch (9) screw rod (10), the crank arm external diameter coupling of (13) of the internal diameter of sleeve (6) and suspension rod (4), suspension rod (4) crank arm (13) can overlap in the sleeve of packing into (6).Suspension rod (4) is by cranking arm (13) and being made up of hinged straight-arm (14), a dead sheave (15) is equipped with in the upper end of straight-arm (14), the negative camber of suspension rod (4) is welded with the reinforcing bar of putting more energy into (16), the positive camber of (13) of cranking arm welds one group four steel plate brackets (17) hanger, bracket has bolt hole respectively on (17), is used to articulate the electronic part (2) of the garden cylindricality fabricate block of being made up of motor, winch spool, slowing-down brake system.The brake system of this electromechanics moving partly (2) adopts outage formula wheel frame brake modes.
The light lifting machine of the fixture type that the utility model provides, crank arm and the straight-arm of its suspension rod adopt hinge to be connected, and can amount to; Two clamping plate of fixed mount adopt hinged, also can amount to; The tube internal upper part of sleeve is equipped with the bearing of vertical setting, and the bearing of horizontal force is equipped with in the interior bottom of sleeve, is used to reduce crank arm when rotating and the friction force of sleeve lining, makes that crank arm can be along quill shaft arbitrarily angled rotation in doing the plane; One side of the bottom of sleeve and fixed mount adopts hinged securement, and when the fixture type clamping frame needed laterally to use, sleeve can be done a right angle adjustment, at this moment, sheds the sleeve hold-doun nut, and fixed mount crossbeam screw is inserted in bolt adjustment on the sleeve, can use as usual after fastening; The brake system of electronic part adopts the brake of outage formula wheel frame, and brake torque is big, in hoisting depth, shut down whenever or have a power failure suddenly, cut off the power supply, lifting rope and weight all can with outage automatic steady brake simultaneously, and maintenance relative static conditions.
The light lifting machine of the utility model fixture type, simple in structure, volume is little, in light weight, easy for installation, lifting force is big, and operation is reliable, the buttress sign indicating number heap that can be widely used in small-sized material lifting, warehousing industry and the farm of building industry unloads, the lifting unloading operations such as removal of home of industrial and mineral enterprises and institutions, is the mutual tool of a kind of multiduty small-sized lifting.
Accompanying drawing is the structural representation of the light lifting machine of the utility model patent fixture type.
