Abstract
The utility model discloses a lifting motion mechanism of a tower crane, which relates to the technical field of cranes, and comprises a rack, a motor, a speed reducer, a brake, a roller, a shaft coupling, and a bearing pedestal. The motor is a secondary motor, and the shaft coupling is a rigid coupling. The secondary motor is connected to the speed reducer through the rigid coupling, and the speed reducer is connected to the brake. An output end of the speed reducer is connected to the roller, and the roller is supported by the rack through the bearing pedestal, and the bearing pedestal is provided with a stopper. The lifting motion mechanism of a tower crane is advantageous in that problems of a tower crane that rising and descending are slow, time is wasted, work efficiency is low, and the volume of a lifting speed reducer is large can be resolved; work efficiency can be improved.
Description
Technical field
The utility model relates to the kinematic mechanism that hoists of hoisting crane technical field, particularly a kind of tower crane.
Background technology
Be likened to " giant's arm " by people, " be drawn in the aerial arc in sky, the hoisting crane of " symbols of power and beauty ", be widely used in each department of national economy and carry out the visual plant of material production and handling.Tower crane is a kind of can vertically hoisting within the specific limits and the machinery of parallel motion article, it is the main construction machinery and equipment in modernization industry and civil construction, the kinematic mechanism major part that hoists of existing tower crane is two extremely above motor-drivens, because the magnetic pole that contains in two extremely above motors increases, its rotating speed reduces, when the tower machine underload or when unloaded rise and fall very slow, lose time, work efficiency is low.The coupler that uses in lifting mechanism is generally the plum blossom elastic coupling, and this coupler weight is larger, poor stability.
The utility model content
The utility model provide a kind of when the tower machine underload or when unloaded rise and fall quick, high stability, the kinematic mechanism that hoists of high efficiency tower crane.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme: a kind of kinematic mechanism that hoists of tower crane, comprise frame, motor, reductor, drg, cylinder, coupler, bearing seat, described motor is connected with reductor by coupler, reductor is connected with drg, and the reductor mouth connects cylinder, and cylinder is supported on frame by bearing seat, bearing seat is provided with limiting device, and motor is two-pole machine; Described coupler is fast coupling, and the convex shoulder on a half a coupler in fast coupling matches and centering with the groove on another half a coupler, and two half a couplers are bolted.
Beneficial effect: the utility model has adopted rotating speed two-pole machine faster,, no matter realized that the tower machine under the unloaded or real state that carries, can guarantee that it is quick when rising and descending, has saved the time, makes cost reduce greatly; Convex shoulder on a half a coupler in fast coupling matches and centering with the groove on another half a coupler, two half a couplers are bolted, friction moment by two half a coupler faying faces transmits, fast coupling lightweight, highly sensitive, low inertia, do not need to safeguard, higher oil resistance and corrosion stability are arranged.
Description of drawings
Fig. 1 is the schematic diagram of the kinematic mechanism structure embodiment that hoists of the utility model tower crane;
Fig. 2 is the schematic diagram of fast coupling in Fig. 1.
The specific embodiment
as Fig. 1, shown in Figure 2, the utility model comprises two-pole machine 1, frame 2, fast coupling 3, drg 4, reductor 6, cylinder 7, bearing seat 8, described two-pole machine 1 is connected with reductor 6 by fast coupling 3, reductor 6 is connected with drg 4, the 6 machine mouths that slow down connect cylinder 7, cylinder 7 is supported on frame 2 by bearing seat 8, also be provided with rear flange 10 between cylinder 7 and bearing seat 8, bearing seat 8 is provided with limiting device 9, two-pole machine 1 includes a pair of magnetic pole, rotating speed is faster, compare with the motor in the lifting mechanism of existing tower crane, can provide larger outputting power for the kinematic mechanism that hoists, make the speed of tower crane rise and fall when underloading or zero load faster, convex shoulder on a half a coupler 11 in fast coupling 3 matches and centering with the groove on another half a coupler 12, and two half a couplers connect by bolt 13, and the friction moment by two half a coupler faying faces transmits.After two-pole machine 1 comes into operation, by the friction lining on drg 4 can control two-pole machine 1 deceleration, stop or keeping halted state, two-pole machine 1 is sent to power in reductor 6 by coupler 3, reductor 6 changes this power into moment of torsion and passes to cylinder 7, reductor 6 is connected with cylinder 7 left ends by forward flange 5, thereby driving cylinder 7 rotates, make the line that is wound around above cylinder 7 loosen or tighten up, at the power supply that can automatically cut off lift system by limiting device 9, stop or give the alarm.
Above-described is only preferred implementation of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
