Abstract
A horizontal double-rope-outlet electric hoist for a lever gear door comprises a speed reducer, a ratchet wheel brake and wire ropes, wherein two wire rope grooves with different rotation directions are turned on a winding drum of the electric hoist, a right-hand rope groove is arranged on the left and a left-hand rope groove is arranged on the right; the wire ropes are both fixed via a rope pressing plate; a right-hand rope guiding device is arranged on the right-hand rope groove, and a left-hand rope guiding device is arranged on the left-hand rope groove; the ratchet wheel brake is arranged between the speed reducer and the winding drum, and a motor device with a tapered brake is arranged at the right end of the winding drum device; and a limiting device is arranged above the motor device with the tapered brake, while a hand-operated release device is arranged at the rear end. The utility model has the advantages of reliable performance, good universality and convenient installation and use. Left-hand threads and right-hand threads are formed on one winding drum, and the corresponding left-hand and right-hand rope guiding devices are equipped, thereby achieving the purpose of bidirectional horizontal traction.
Description
Technical field: the utility model relates to a kind of lever gear door with horizontal double-rope electric block.
Background technology: Chinese aircraft industry is accompanied by China's economic and has obtained great-leap-forward development, takes turns upsurge newly-built, the enlarging airport thereby started one in the whole nation.Yet the domestic air mail construction has all run into a very awkward problem: " quality of the large-scale hangar door of domestic manufacturing can not get guaranteeing ".One of them chief reason is exactly that the lifting mechanism at gate can not get good solution always.Spend huge foreign exchange to buy external product so have to.All there is a common ground in the large scale industry lever gear door, and door body width is big, and the door body is from heavy, and the door body weight does not wait from 2 tons～25 tons.Original industrial door elevator lifting capacity maximum then is 1 ton, can not satisfy the needs of newly-built development far away.Domestic also useful hoisting machine is as the precedent of lifting mechanism, be fixed on hoist engine underground, by a series of fixed, movable pulley hoists and descend.Have following defective after the use: 1, volume is big, and rope roll is long, and swing property is big, and torsion changes greatly, poor stability.2, operating principle becomes fixing motion from freely moving both vertically, and is eccentric big.3, since wire rope and wire rope barrel dliameter to the angle of a variation of cross section formation, no guide rope device, unbalance stress causes the wire rope breakdown.4, because all hoisting mechanisms need a plurality of component to be assembled, and assembly precision is poor, inconvenience is installed, noise is big.5, since brake system have only 1, as wearing and tearing after can cause brake failure, more than all situations cause very big potential safety hazard.
Summary of the invention: the purpose of this utility model will provide a kind of lever gear door with horizontal double-rope electric block exactly, and it can overcome the existing defective of above product well, and can reach the purpose of the required bivector traction of lever gear door.The purpose of this utility model is to realize like this, lever gear door is with horizontal double-rope electric block, formed by reducer, automatic load sustaining brake, wire rope, it is characterized in that: the wire rope grooving of two kinds of different rotation directions of turning on the reel of electric block, the left side is the dextrorotation grooving, and the right is left-handed grooving, and wire rope is all fixed with rope guarding plate, the dextrorotation grooving is provided with the dextrorotation rope guide, and left-handed grooving is provided with left-handed rope guide; Be provided with automatic load sustaining brake between reducer and the roll device, the roll device right-hand member is provided with the electric machine of band taper braking, and the electric machine top of band taper braking is provided with stopping means, and the rear end is provided with hand release.The utility model is dependable performance not only, and versatility is good, easy to install.On a reel, left and right hand thread is set, and prepares the corresponding left and right rope guide that revolves, thereby reach the purpose that two-way horizontal draws.

The specific embodiment: the utility model is described in further detail below in conjunction with accompanying drawing;
Lever gear door is with horizontal double-rope electric block, formed by reducer 1, automatic load sustaining brake 2, wire rope 4, it is characterized in that: the wire rope grooving of two kinds of different rotation directions of turning on the reel of electric block, the left side is the dextrorotation grooving, the right is left-handed grooving, wire rope 4 is all fixing with rope guarding plate 3, and the dextrorotation grooving is provided with dextrorotation rope guide 5, and left-handed grooving is provided with left-handed rope guide 7; Be provided with automatic load sustaining brake 2 between reducer 1 and the roll device 6, roll device 6 right-hand members are provided with the electric machine 8 of band taper braking, and electric machine 8 tops of band taper braking are provided with stopping means 9, and the rear end is provided with hand release 10.During concrete enforcement, as shown in Figure 2, the wire rope grooving of two kinds of different rotation directions of turning on the reel of electric block, the left side is the dextrorotation grooving, the right is left-handed grooving, two isometric wire rope are all fixing with rope guarding plate 3, on the reel shell, following symmetric position is respectively opened a rope outlet, twine by diagram, in the winding process, the dextrorotation grooving is installed dextrorotation rope guide 5, and left-handed grooving is installed left-handed rope guide 7. and driven reel rotation by shaft coupling through the reducer that hoists when the motor that hoists of electric block, and the wire rope that is wrapped on the reel moves into simultaneously in the horizontal direction or lays out.For avoiding brake failure or driving to cause security incident, the ratchet deadman's brake has been installed on the slow-speed shaft roll device.Tail end at motor has been installed hand release, and waiting in power failure in particular cases can safe puts down the door body.In use, the utility model is fixed on the body crossbeam by Fig. 3, suitably regulates wire rope length and can satisfy the requirement that the lever gear door body opens and closes distance.Press Fig. 4 and install, the conversion pulley block ratio can not only constantly change a body lift heavy, and can change the lifting velocity of door body according to customer requirement.
