Description
Technical field
The utility model relates to a kind of pulley type Simple material carrying implement.
Background technology
Pulley type Simple material carrying implement is a kind of small-sized movably Simple material hoisting transportation equipment.It is widely used in rural area handling grain, vegetables, house owed by a citizen or indoor decoration handling masonry, furniture, the comparatively lifting carrying work of labor intensive such as factory, warehouse, harbour lifting material.It is little that it has volume, lightweight, is easy to carry about with one, quick for installation, easy to operate, the features such as function admirable.And operate steadily, flexible operation, has alleviated laborer's labour intensity greatly, has improved work efficiency.Tradition Simple material carrying implement keystone configuration is generally comprised of engine installation, coaster, arm, supporting leg, and arm is connected with bolt with supporting leg, and Power Drive Unit is arranged on coaster, and coaster is placed on the track of arm.Therefore its installing/dismounting is very convenient.But this type of physical construction is simple, and design defect is large, lack necessary safety control, there is in actual use very large potential safety hazard.
At present application more widely pulley type Simple material carrying implement structure mainly by being formed by engine installation, coaster, arm, supporting leg.Member, according to installing and using explanation after installation site installs, is press-fited and is press-fitted weight at the reserved location of supporting leg according to rated load, complete fixing.In use, be press-fitted the resistance to overturning that counterweight effect that weight brings ensures body.Power when engine installation provides operation.Engine installation mainly comprises electrical motor, retarder, power-transfer clutch, drg, rope roll and steel rope, or is comprised of electric block and steel rope.But this carrying implement resistance to overturning is poor, resistance to overturning is mainly derived from and is press-fitted weight, machinery in use can produce vibrations, be press-fitted weight and can depart from gradually the correct position that is press-fitted along with vibrations, when operating personal does not have in time when being press-fitted weight and relaying in correct position, just may there is potential safety hazard in machinery.Lack hoisting capacity safety control, hoisting capacity safety control is the important safety control setup that ensures that machinery is only worked within the scope of rated load, and in real work, overload operation is the maximum potential safety hazard that causes mechanical movement accident.Lack lifting altitude restraint device.Lifting altitude restraint device is when load-engaging device rises to the rising limit of design code, should be able to stop load-engaging device and continue the safety guard rising.
Utility model content
The technical problems to be solved in the utility model is the above-mentioned defect that how to overcome prior art, and a kind of pulley type Simple material carrying implement is provided.
For solving the problems of the technologies described above, this pulley type Simple material carrying implement comprises arm, supporting leg, coaster, upper topmast support and engine installation, wherein said supporting leg and arm are connected firmly, described coaster is arranged on the track of arm, described upper topmast support is arranged on arm top, described engine installation is arranged on coaster, this engine installation comprises electric block, steel rope and suspension hook, wherein wirerope-winding is on the rope roll of electric block, suspension hook and steel rope are connected firmly, steel rope drives the rotating of rope roll to complete the lifting of suspension hook by electric block, on described coaster, in electric block installed position top, be provided with hoisting capacity control setup, described electric block below is provided with lifting altitude limiting control device.
As optimization, described hoisting capacity control setup is comprised of freight weight limit spring, spring housing box, anti-overweight limit switch, switch touch panel, and described lifting altitude limiting control device is mainly comprised of recoil spring and preventing colliding with top limit switch.
So design, under mode of operation, freight weight limit spring can accurately measure hook load and whether exceed rated load, when hook load exceeds rated load, spring touches anti-overweight limit switch, cuts off the electricity supply, stop material to continue to rise, thereby ensure that machinery can overload operation; Load-engaging device rises to after limiting altitude, and the collision plectrum on steel rope touches recoil spring, and recoil spring is subject to force compresses, touches preventing colliding with top limit switch, cuts off the electricity supply, and stop load-engaging device to continue to rise, thereby protection equipment is not damaged.
As optimization, described upper topmast support is mainly comprised of vertical rod and jack screw rod, and wherein jack screw rod screws in the tapped bore of vertical rod.
So design, the tapped bore that jack screw rod screws in vertical rod can form easy screw-jack, by the length of rotation jack screw rod adjustable support.After machinery combination fixedly completes, upper topmast support is arranged on to the installation site setting on arm, then rotates jack screw rod, in adjustments, topmast supports, and make it and install top and can hold out against, thus the stability of guarantee complete machine.
A kind of pulley type Simple material of the utility model carrying implement reasonable in design, use simple operation, it increases upper topmast support, improves complete machine stability and safety.The increase of elevating capacity limiting apparatus, guarantees the machinery work that in use can not overload.Lifting altitude restraint device guarantees that equipment is in operation and can not rush to summit, support equipment safety.It is the desirable regeneration product of prior art.
