Abstract
The present utility model discloses a rope releasing protective device which includes casing, shifting plate, over loading switch, fixing bolt, rope releasing switch, protective sleeve, small spring, crown bar, baffle plate, big spring, pulley clamping plate and pulley, it belongs to elasticity control electric linkage type rope releasing device and is mainly used in various working lifter to prevent the steel rope from releasing and making the rope in disorder. It is light in structure and can be arranged conveniently, it has high reliability and overload preventing function.
Description
Technical field
The utility model relates to mechanics and person in electronics, a kind of specifically rope creep protection device.
Technical background
" adopt the elevator of single wire rope or counterweight steel rope also locking cord switch should be set; when slack rope appears in elevator, this switch cuts off the braking of control circuit drg to State Standard of the People's Republic of China GB10055 " building hoist safety rule " regulation immediately." industry standard JGJ88 " portal frame and derrick material elevator technical specification of security " requires gig should establish overload protection device, when load surpasses rated load, cuts off the power supply that hoists.Present construction lifter excess load, rope creep protection device generally are loaded on the lower sheave or are contained in Tian Liangshang, and existing fender guard often can't normal operation because of the long electric system that makes of circuit when adopting low pressure control because of protector installation site height.And because protector directly is subjected to lineoutofservice signal pull, structure heaviness, installation inconvenience; The protector installation site is low excessively, and electric system protection is relatively poor, again since adopt single spring not only done rope creep protection but also done overload protection flutter when starting bigger, the reliability of protection and poor accuracy.
The utility model content
The purpose of this utility model is for solving the shortcoming of present kind of protector, the anti-overload rope creep protection device that a kind of structure is light and handy, easy for installation, reliability is high being provided.
The technical solution of the utility model
A kind of rope creep protection device; comprise shell; dial plate; the overload switch; bolt of rear end plate; the slack rope switch; protecting sleeve; little spring; push rod; baffle plate; big spring; the pulley clamping plate; pulley; it is characterized in that: activity is placed on the push rod in the shell of cast; stretch out from the hole of shell one end; captive joint with the pulley clamping plate that pulley is installed; the big spring that is connected with the shell nose end is enclosed within on the push rod in the shell; ring-like baffle plate that is mutually permanently connected and protecting sleeve are successively on the movable sleeve push rod; activity is with a little spring on the push rod in the protecting sleeve; the one end is connected with baffle plate; the other end is connected with a ring-like boss on the push rod; the port of protecting sleeve extends the height two side; low sidewall flexibly connects mutually with the boss of push rod end; high sidewall is captiveed joint with group plate, and contact faces the overload switch of dialling the front edge of board bending place and the end slack rope switch that contact faces push rod is all placed in the enclosure.
Principle of the present utility model
Push rod links to each other with pulley by the pulley clamping plate, and its suffered axial force increases accordingly with the pull of steel wire size or reduces.When steel rope was lax, pulley was not subjected to steel wire rope tension, withstands the slack rope switch at little spring effect lower push rod, made the slack rope switch be in moving disconnected state, the outage of control decline contactless switch.When the steel rope tensioning, pulley is subjected to steel wire rope tension, and little spring elastic force is less than steel wire rope tension, and push rod breaks away from the slack rope switch, makes the slack rope switch be in closure state, and control decline contactless switch can normal operation.Protecting sleeve can protect little spring not pressed also, increases system stiffness, reduces chatter, makes rope creep protection reliable.When elevator craning cage overloaded, steel wire rope tension overcame the elastic force of big spring, and protecting sleeve is moved in the enclosure, made the overload switch be in moving disconnected state by pulling out plate, controlled the contactless switch outage that hoists.
Effect of the present utility model
The utility model belongs to the locking rope device of elastic force control electrical interlocks type, is mainly used in all kinds of building hoists and prevents that steel rope from getting loose and cause disorder cable that its structure is light and handy, easy for installation, reliability is high, has anti-overload feature.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1.A kind of rope creep protection device; comprise shell 1; pull out plate 2; overload switch 3; bolt of rear end plate 4; slack rope switch 5; protecting sleeve 6; little spring 7; push rod 8; baffle plate 9; big spring 10; pulley clamping plate 11; pulley 12; activity is placed on the push rod 2 of 1 li on the shell of cast; stretch out from the hole 13 of shell 1 one ends; captive joint with the pulley clamping plate 11 that pulley 12 is installed; the big spring 10 that is connected with shell 1 hole 12 ends is enclosed within on the push rod 8 in the shell 1; ring-like baffle plate 9 that is mutually permanently connected and protecting sleeve 6 are successively on the movable sleeve push rod 8; activity is with a little spring 7 on the push rod 8 in the protecting sleeve 6; the one end is connected with baffle plate 9; the other end is connected with a ring-like boss 14 on the push rod 8; the port of protecting sleeve 6 extends the height two side; low sidewall 15 flexibly connects mutually with the boss 16 of push rod end; high sidewall 17 with pull out plate 2 and captive joint, contact faces the end slack rope switch 5 that the overload switch 3 that pulls out the front edge of board bending place and contact face push rod and all is placed in the shell 1.Shell 1 adopts Φ 48 * 3mm steel pipe to make, and electric elements and spring all are contained in the steel pipe, and protective is good, and the connectivity of steel pipe and elevator is good, particularly needs only to link to each other with support body with common fastener on the gantry frame type elevator.Overload switch 3 is fixed on the shell 1, and break-make is pulled out the control of plate 2, and its position can be adjusted by bolt of rear end plate 4; Protecting sleeve 6 with pull out plate 2, baffle plate 9 is integrally welded, the slack rope switch is fixed on the protecting sleeve 6, break-make is subjected to the control of push rod 8; Under the elastic force effect of pulley tensile force and big little spring, push rod 8 can be done axially reciprocating in shell 1 and protecting sleeve 6, and protecting sleeve 6 can move reciprocatingly in shell 1.
