Abstract
The utility model discloses a synchronous frequency conversion lifting machine of permanent magnetism, including holding surface and reel, be equipped with two stoppers on the holding surface, the reel erects on two stoppers, the one end of the center pin of reel is passed through the low -speed shaft coupling and is connected with the PMSM transmission. The beneficial effects of the utility model are that, start steadily, output torque is big.
Description
Technical field
The utility model relates to mine hoist equipment field, particularly a kind of permanent-magnet synchronous frequency conversion gig.
Background technology
The parameters in series of China's multi-rope friction type mine hoist is worked out from nineteen sixty, and current kind has tower and floor type; Rope number there are two ropes, four ropes, six ropes; Diameter structure reaches 5.5m; Main gear form has electrical motor to be dragged and low-speed motor direct connection two kinds by retarder.China 1958 design produces First 2m tetra-and to restrict tower friction-type mine hoist, is applied in Fuxin Wu Longkuang.Nineteen sixty is designed again and produces 3m tetra-rope friction type mine hoist, uses in Ningxia Shizuishan two ore deposit.From then on China also starts to apply tower multi-rope friction type mine hoist.
Due to shockproof needs, each mine user requires the supply of material of ground-type multi-cable friction-type mine hoist one after another, so utilized Henan great Yu Gou to limit because of floor area in 1977, when intrinsic double-cylinder single rope gig cannot be installed, when without any console model multi-cables hoist bibliography, paddled one's own canoe strength completely, through effort and the tackling key problem of 5 months, in October, 1977, China First 2m duplex type floor type mine hoist is born at China's large valley ditch.At one four rope floor type friction mine hoist of nineteen eighty-two Luoyang mining machinery research institute design trial-production, in Guangdong, red industrial and mineral runs subsequently, and nineteen eighty-three is designed by Shanghai Metallurgy Mine Machinery Factory and produces the restrict floor type friction drive hoist of DC low-speed of 3m tetra-and apply and qualification in Chang Guang colliery, China Zhejiang.From then on, tower and the ground-type multi-cable friction mine hoist of China is extensively adopted by mine, but due to aspects such as product design, raw MAT'L, processing technology and manufacture levels, still there is sizable gap with noise etc. in technical performance, electric quantity consumption, transmitting torque, life-span, reliability in actual use compared with international most advanced level to make product.Traditional gig drive system adopts asynchronous motor, retarder to drive equipment to rotate, the obvious shortcoming of type of drive of this system is: drive-train efficiency is low, energy consumption is large, startup is steady, and heavy load starting difficulty, these shortcomings directly affect the whole efficiency of drive system.The daily maintenance to parts such as retarders and replacing are very frequent, and repair apparatus still needs supporting maintenance drive system, complex structure.
Utility model content
The purpose of this utility model is to solve the problem, and devises a kind of permanent-magnet synchronous frequency conversion gig.
Realizing above-mentioned purpose the technical solution of the utility model is, a kind of permanent-magnet synchronous frequency conversion gig, comprise bearing surface and reel, described bearing surface is provided with two drgs, described reel stand is located on two drgs, and one end of the center shaft of described reel is in transmission connection by low-speed shaft coupler and permagnetic synchronous motor.
Described reel is erected on two drgs by the two ends of its center shaft.
One end of described drum center axle is run through the drg corresponding with it and is in transmission connection with low-speed shaft coupler.
The turning cylinder of described low-speed shaft coupler and permagnetic synchronous motor is in transmission connection.
The permanent-magnet synchronous frequency conversion gig utilizing the technical solution of the utility model to make, has efficient, energy-conservation, low noise, non-maintaining, Driving Torque large, starts steadily, advantage that permanent torque controls.
Accompanying drawing explanation
Fig. 1 is the structural representation of permanent-magnet synchronous frequency conversion gig described in the utility model;
In figure, 1, reel; 2, drg; 3, low-speed shaft coupler; 4, permagnetic synchronous motor; 5, bearing surface.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is specifically described, as the structural representation that Fig. 1 is permanent-magnet synchronous frequency conversion gig described in the utility model, as shown in the figure, a kind of permanent-magnet synchronous frequency conversion gig, comprise bearing surface (5) and reel (1), described bearing surface is provided with two drgs (2), and described reel stand is located on two drgs, and one end of the center shaft of described reel is in transmission connection by low-speed shaft coupler (3) and permagnetic synchronous motor (4).Wherein, described reel (1) is erected on two drgs by the two ends of its center shaft; One end of described reel (1) center shaft is run through the drg corresponding with it and is in transmission connection with low-speed shaft coupler; Described low-speed shaft coupler (3) is in transmission connection with the turning cylinder of permagnetic synchronous motor.
The feature of the technical program adopts permagnetic synchronous motor to replace traditional asynchronous dynamo and the unitized construction of retarder, thus realize the advantage such as the low noise of gig, non-maintaining, Driving Torque large, it is steady to start, permanent torque control.Common asynchronous dynamo replaced by the permagnetic synchronous motor of employing slow speed of revolution, high pulling torque, thus realizes stepless time adjustment function by permanent-magnet synchronous system, and anti-overload ability is very strong.
Technique scheme only embodies the optimal technical scheme of technical solutions of the utility model; those skilled in the art all embody principle of the present utility model to some variations that wherein some part may be made, and belong within protection domain of the present utility model.
