Abstract
The utility model belongs to an overload limiting device for a hoisting basket which is towed by a hoist. The utility model is mainly composed of a ground pulley (1), an inner sliding bush (2), a contact plate (6), a combined spring (3), an inner core screw bolt (8), an outer bush (7), a travel switch (4), an oblique support plate (10) and a base (9). The utility model is characterized in that the device is not concatenated on the steel cable of the hoist, but is arranged on the flat ground. The utility model has the advantages of simple structure, low cost, light weight, easy maintenance, sensitive response to overload, convenience and practicability.
Description
The utility model belongs to a kind of overload restraint device of hoisting machine traction hanging basket.
In building operation, promote derrick Nei Changyin hanging cradle overload and hoisting machine steel rope abrasion and take place to break rope and hanging basket falling accident, cause casualties and property damage.The known technology of the load limiter of hoisting machine and hanging basket has: mechanical type load limitation device (GG87211754), hoisting crane type load restraint device (CN87204118U), be used for the overload protection device (GG85101376) of hoisting machine one kind equipment.Preceding two kinds of devices all are to be installed in series on the cable wire of weight-lifting equipment, and its power supply wiring is long and use inconvenient; A kind of device in back, because of the structure more complicated, the cost height also is unsuitable for and applies.Widely used hoisting machine and hanging basket in the building operation at present overload in fact often, how to reduce disconnected rope of hoisting machine and hanging basket falling accident effectively and take place, and ensure that construction safety and Plant in good condition are the current problems that need solve.
The purpose of this utility model provides and a kind ofly is installed on the level land, simple in structure, cost is low, in light weight, easy-maintaining, overload are quick on the draw, convenient and practical hoisting machine and the load limiter of hanging basket.
The technical solution of the utility model is achieved in that the lower sheave 1 of hoisting machine steel rope is installed on the panel of inner sliding sleeve 2, the base plate of inner sliding sleeve 2 is provided with inner sliding sleeve axis hole 11, with inner core bolt 8, by inner sliding sleeve axis hole 11 cluster spring 3 is pressed on the base plate in the inner sliding sleeve 2, inner sliding sleeve 2 is placed in the overcoat 7, inner core bolt 8 passes the overcoat axis hole 14 on overcoat 7 base plates, with inner sliding sleeve 2 with overcoat 7 compresses and fixing, overcoat 7 is welded in oblique board 10 backs to be fixed on oblique board 10 on the base 9 with bolt, be fixed with the touch panel 6 of projection on the inner sliding sleeve 2, cluster spring 3 stressed being compressed when hoisting machine is loaded, touch panel 6 is corresponding moving in the long slot bore 5 that overcoat 7 is provided with, touch panel 6 is run into the contact of the travel switch 4 of long slot bore 5 upper ends of being fixed in overcoat 7 when the hanging cradle overload of hoisting machine traction, this moment, the power supply of hoisting machine was cut off, thereby had realized the purpose of restriction overload.
Below in conjunction with accompanying drawing description is made in enforcement of the present utility model.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that parts of the present utility model are the structural representation of inner sliding sleeve 2.
Fig. 3 is that parts of the present utility model are the structural representation of overcoat 7.
According to Fig. 1, Fig. 2, shown in Figure 3, the utility model mainly is made of lower sheave 1, inner sliding sleeve 2, touch panel 6, cluster spring 3, inner core bolt 8, overcoat 7, travel switch 4, oblique board 10, base 9.Inner sliding sleeve 2 is that the cross section is circular or square hollow cylinder, the head end of cylindrical shell extends two panels, panel is provided with the axis hole 12 that lower sheave 1 usefulness is installed, and the bottom back cover of cylindrical shell also is provided with inner sliding sleeve axis hole 11 on its base plate, be fixed with the touch panel 6 of a projection in the cylindrical shell bottom; Overcoat 7 is that the cross section is circular or square hollow cylinder, head end at cylindrical shell is provided with two relative breach 13, be provided with overcoat axis hole 14 at cylindrical shell bottom back cover and on its base plate, the position, middle and lower part on cylindrical shell has long slot bore 5, and travel switch 4 is fixed on the cylindrical shell of long slot bore 5 head ends; Cluster spring 3 is inside and outside twice stage clip, and outer spring is dextrorotation, and interior spring is left-handed.All parts completion of processing of the present utility model and get all the ready after, according to shown in Figure 1, cluster spring 3 is pressed on the base plate in the inner sliding sleeve 2 by inner sliding sleeve axis hole 11 with inner core bolt 8, inner sliding sleeve 2 is placed in the overcoat 7, inner core bolt 8 passes overcoat axis hole 14 on overcoat 7 base plates with inner sliding sleeve 2 with overcoat 7 compresses and fixing, overcoat 7 is welded in oblique board 10 backs oblique board 10 is fixed on the base 9, with bolt lower sheave 1 is installed on the axis hole 12 of two panels that inner sliding sleeve 2 head ends stretch out at last with bolt.Will carry out the load location after the utility model has been made, and the both sides of long slot bore 5 correspondingly engrave the load witness marker on overcoat 7.
Claims (3)
