Abstract
The utility model relates to a manual releasing device of electric chain hoist back brake to be mainly used in manual release of an electric chain hoist in a ship; the utility model is characterized in that the releasing device comprises a supporting frame (1), a plug (2), a handle (3), a pushing rod (4), a nut (5) and a pressing spring (6); wherein the pushing rod (4) passes through and is vertically connected with the center of the supporting frame; the plug (4) is connected with the left end of the pushing rod (4); the upper end of the handle (3) is connected with the supporting frame (1); the middle part of the handle is sleeved on the right end of the pushing rod (4); the nut (5) is rotatedly provided on the handle (3) provided on the internal side of the pushing rod (4); the pressing spring (6) is provided between the nut (5) and the supporting frame (1). The utility model has the advantages that the electric chain hoist may need no electricity to slowly drop the heavy object to the ground by utilizing the manual releasing device, when power fails or other emergence happens, which offers the operator convenience and improves the safety of the electric chain hoist.
Description
Technical field
The utility model relates to a kind of electric block, brakes hand release after especially relating to a kind of electric block.Be mainly used in the manual releasing of electric block peculiar to vessel.Belong to the elevator machinery technical field.
Background technology
Before the utility model was made, traditional electric block did not all have hand release.When having a power failure or emergency situation such as electrical accident occurring, its elevating function will lose efficacy, especially in the process of hoisting heavy, and the prominent emergency situation such as powers failure grade of meeting, weight is suspended in the air, can't discharge.If the electric block brake failure, weight will descend (free-falling body) under the state without any braking, so there is great potential safety hazard in it, and the article that hang also can be damaged, and cause great economic loss.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of need not to brake hand release behind electric power, simple to operate, the safe and reliable electric block.
The purpose of this utility model is braked hand release after being achieved in that a kind of electric block, comprise bracing frame, top, handle, push rod, nut and pressure spring, described push rod vertically is connected to the bearing support center, the top is connected in the push rod left end, the handle upper end links to each other with bearing support, intermediate sleeve places the push rod right-hand member, revolves on the handle of push rod inboard and puts nut, and pressure spring places between nut and the bearing support.
Brake hand release behind the utility model electric block, described top is connected in the push rod left end by bearing.
Brake hand release behind the utility model electric block, the casing right-hand member center of described electric block offers perforation, and the top is passed this perforation and matched with the right-hand member of electric block motor crankshaft.
Principle of work: this hand release is used for the motor that glancing impact electric block motor shaft moves backward.During the hand release operation, driving handle comes directly towards the top arbor that withstands of head to left movement left, and this moment, brake hoop also and then to left movement, lost brake action to motor, and motor is because the gravity of object rotates, and weight is transferred.
The beneficial effects of the utility model are: when electric block take place to have a power failure or during other emergency situations, can not need electrification at hoisting heavy, use this device that weight is slowly transferred to the ground.Easy to use, improved the safety that electric block uses.
Description of drawings
Fig. 1 is the overall structure scheme drawing of braking hand release behind the utility model electric block.
Among the figure: bracing frame 1, top 2, handle 3, push rod 4, nut 5, pressure spring 6, arbor 7, brake hoop 8, bearing 9, motor 10, perforation 11.
The specific embodiment
Referring to Fig. 1, the utility model is to brake hand release behind a kind of electric block, mainly is made up of bracing frame 1, top 2, handle 3, push rod 4, nut 5 and pressure spring 6.Described bearing support 1 is fixedly connected on electric block casing right-hand member, push rod 4 vertically is connected to bearing support 1 center, top 2 is connected in push rod 4 left ends by bearing 9, the casing right-hand member center of electric block offers perforation 11, top 2 is passed this perforation and is matched with the right-hand member of electric block motor 10 arbors 7, and handle 3 upper ends and bearing support 1 join, and intermediate sleeve places push rod 4 right-hand members, revolve on the handle 3 of push rod 4 inboards and put nut 5, pressure spring 6 places between nut 5 and the bearing support 1.
The utility model hand release must intermittent operation, slowly discharges, and forbids continuous releasing operation.
