Description of drawings
Fig. 1 is a front view of the present utility model;
Fig. 2 is a left view of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
High-lift electric block as shown in Fig. 1, Fig. 2 has main frame plate 1, is arranged with the hoist motor reel of electrical motor 2 of two 2, two of electrical motors that hoist on the main frame plate 1 and is connected with retarder 3 respectively, is connected with reel 4 on the retarder 3 respectively.Main frame plate 1 below has suspension hook plate 5, and axis of symmetry is provided with two fixed pulleys 6 on the suspension hook plate 5, and the pars intermedia of suspension hook plate 5 lower ends is fixed with suspension hook.Also have a conductor rope 8, the two ends of conductor rope 8 are wrapped in respectively on two reels 4, and the pars intermedia of conductor rope 8 passes two fixed pulleys 6 respectively.
Be provided with limit for height cutoff apparatus 9 in suspension hook plate 5 upper ends.
Principle of work:
The high-lift electric block of CD1 type 5t in the present embodiment is used for ship-building gantry crane to be used, and during use, earlier electric block and running trolley is linked together.In the present embodiment, main frame plate 1 is fixed together by axle with link span, and running trolley 10 is fixed on above the link span.The motor reel that hoists links to each other with the retarder high speed shaft by rubber tire formula elastic coupling.When the electrical motor 2 energising rotations that hoist drive the rotation of retarder high speed shaft, and with drive torque by gear transmission to retarder 3 afterbody big gear wheels, gear is being connected with hollow shaft by spline, hollow shaft is connected with reel 4 by spline again, and the moment by deceleration transmission makes reel 4 rotations for this reason.Because conductor rope 8 two ends are wrapped in respectively on two reels 4, and conductor rope 8 middle parts pass two fixed pulleys 6 respectively, and therefore two reels 4 rotates simultaneously and conductor rope 8 twined or disengagement reel 4 and suspension hook 7 is hoisted or descend, and finish the function of lifting mechanism.When the startup electrical motor that hoists, weight worked being raised to suitable height, to restart service meter weight is transported to appointed positions, running trolley is in the lower edge walking of single steel I-beam.Adopt the wheel on two direct motor drive running trolley both sides during walking.Running trolley descends for preventing weight when walking, is provided with a magnet stopper on lifting mechanism.Braking is to rely on the pressure of spring that inside and outside dish is compressed, and principle is similar to friction clutch, utilizes electromagnet to switch on when unclamping and holds later outer dish and inside and outside dish is unclamped.The circuit of magnet stopper is in parallel with the circuit of the electrical motor that hoists, as long as therefore hoist electrical motor one startup, magnet stopper unclamps, and makes the upper and lower lifting of weight freely; When electrical motor was closed, then magnet stopper also cut off the power supply, and electromagnetic attraction disappears, and under the pressure effect of spring, internal and external disk is tightly pushed down, and plays the effect of braking.Hoist thereby finish, stop and a series of actions of descending comes the handling weight.
Present stage is all come hoisting heavy with dolly when the hoisting heavy of 120m high-altitude, complex structure and heaviness are now used high-lift electric block hoisting heavy, and it is little, in light weight, simple to operate, easy to use that electric block itself has a volume.Because this electric block has adopted two electrical motors that hoist, two reels, the conductor rope two ends are wrapped in respectively on two reels simultaneously, make the length of reel when hanging the weight of 120m, reel length has reduced half, smaller volume, and lifting velocity is the twice of common cucurbit speed, improved work efficiency.
