Abstract
The utility model relates to a manual releasing device of electric chain hoist front brake to be mainly used in the manual release of the electric chain hoist in a ship; the electric chain hoist front brake manual releasing device comprises a supporting frame (1), a tension rod (2), a nut (3), a handle (4) and a tension sleeve (5); wherein the tension rod (2) passes through and is vertically connected with the center of the supporting frame (1); the left end of the tension rod (2) is connected with the tension sleeve (5); the upper end of the handle is connected with the supporting frame (1); the middle part of the handle is sleeved and positioned on the left end of the tension rod (2); nuts (3) are rotatedly provided on the handles (4) provided on the internal and the external sides of the tension rod (2). 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, especially relates to the preceding braking of a kind of electric block hand release.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, and a kind of braking hand release before electric power, simple to operate, the safe and reliable electric block that need not is provided.
The purpose of this utility model is braked hand release before being achieved in that a kind of electric block, comprise: bearing support, pull bar, nut, handle and help pull a cart, described pull bar vertically is connected to the bearing support center, the pull bar left end connects helps pull a cart, described handle upper end links to each other with bearing support, intermediate sleeve places the pull bar right-hand member, revolves on the handle of pull bar medial and lateral and puts nut.
Braking hand release before the utility model electric block, described helping pull a cart is connected in the pull bar left end by bearing.
Braking hand release before the utility model electric block, the described endoporus left end of helping pull a cart is provided with negative thread, corresponding to this negative thread, the arbor right-hand member of electric block motor with matching is provided with outside thread, and the casing right-hand member center of electric block offers perforation.
Principle of work: this hand release is used for the motor that glancing impact electric block motor shaft moves forward.During the hand release operation, should earlier two nuts on the pull bar of handle the right be unclamped, pass the middle perforation of electric block motor case right-hand member and the right-hand member of motor crankshaft with helping pull a cart and tighten by screw thread.During this period, nut on the pull bar of the handle left side is answered corresponding adjusting, after adjusting finishes, spur handle to the right, because motor crankshaft is screwed in helping pull a cart, arbor moves right, the brake hoop of motor also and then moves right, brake hoop loses 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 before the utility model electric block.
Among the figure: bearing support 1, pull bar 2, nut 3, handle 4, help pull a cart 5, arbor 6, brake hoop 7, perforation 8, bearing 9, motor 10.
The specific embodiment
Referring to Fig. 1, the utility model is a braking hand release before a kind of electric block, mainly by bearing support 1, pull bar 2, nut 3, handle 4 with help pull a cart and 5 form.Described bearing support 1 is fixedly connected on electric block casing right-hand member, pull bar 2 vertically is connected to bearing support 1 center, help pull a cart and 5 be connected in pull bar 2 left ends by bearing 9, the 5 endoporus left ends of helping pull a cart are provided with negative thread, and corresponding to this negative thread, arbor 6 right-hand members of electric block motor 10 with matching are provided with outside thread, and the casing right-hand member center of electric block offers perforation 8, handle 4 upper ends link to each other with bearing support 1, and intermediate sleeve places pull bar 2 right-hand members, revolve on the handle 4 of pull bar 2 medial and lateral and put nut 3.
The utility model hand release must intermittent operation, slowly discharges, and forbids continuous releasing operation.
