Abstract
The utility model discloses a single-rope wound elevator employing an expansion sleeve connection manner, composed of a motor and an elevator cylinder, wherein connection between the motor and the elevator cylinder is realized through a brake wheel and a coupling half; the connection manner of the motor and the elevator cylinder is a connection manner by employing an expansion connecting sleeve. The single-rope wound elevator is easy for mounting and demounting, and long in service life.
Description
Technical field
The utility model relates to single rope winding hoist
Background technology
The single wire winding type mine gig that uses at present is made up of electrical motor and elevator drum, and both adopt the elastic coupling connection mode.Elastic coupling is made up of brake wheel, half a coupler, rod pin parts such as (pins).When mine hoist need promote or transfer, motor passed torque to reductor through coupler, thus the action that mine hoist is promoted or transfer.
The tradition single rope winding hoist has following shortcoming owing to adopt the elastic coupling connection mode, and 1, because the connection mode of elastic coupling and motor, reductor is that interference has key to be connected, so install, dismounting is inconvenient, it is big to change difficulty, the working strength height.2, the intensity of rod pin is low, and service life is low.3, there have key to connect wearing and tearing in the course of the work to be big.
Summary of the invention
The utility model is to overcome the deficiency that the existing connection mode of single rope winding hoist is brought, and makes improvements, and provides a kind of and is easy to install, the single rope winding hoist of dismounting and long service life.
A kind of employing swelling cover bonded assembly single rope winding hoist is made up of electrical motor and elevator drum, and both realize being connected through brake wheel and half a coupler, it is characterized in that, both connection modes adopt the expansion coupling sleeve connection mode.
Expansion coupling sleeve is called for short the swelling cover, and it comprises expansion set and overcoat, is the keyless device between a kind of axle and the axle sleeve, is novel advanced person's in a kind of modern age mechanical basic part.When expansion set is fixed to the correct position of axle sleeve (hub), tight a bolt by given moment, the taper inner ring applies diametral load to axle sleeve, and this pressure friction links transmitting large torque and load safely.It can apply gripping power from the outside to axle sleeve through overcoat, makes to form mechanical compress between axle and the axle sleeve and cooperate, and transfer torque, expansion set itself does not transmit any moment and load.
This connection mode is compared with connection mode in the past and is had the following advantages:
1, expansion set manufacturing and installation are simple, the axle of expansion set and the processing in hole are installed require high-precision production tolerance unlike the interference fit that kind.Expansion set need not heat when installing, cooling or pressurized equipment, need only bolt moment on request be tightened to get final product.And easy to adjust, can wheel hub be adjusted to desired location easily on axle.The swelling cover also can be used for connecting the part of weldability difference.
2, the long service life of expansion set, intensity is high.Expansion set relies on frictional transmission, does not weaken there is keyway by joint piece, does not also have relative motion, can not produce wearing and tearing in the work.
3, expansion set will lose the connection effect when overload, can protect gig to be without prejudice.
4, the expansion set connection can be born multi-load, and its structure can be made multiple style.According to the installation load size, can also a plurality of expansion set series connection use.
5, expansion set convenient disassembly, and have good interchangeability.Because expansion set can combine the propeller boss of big tolerance clearance, during dismounting bolt is unscrewed, and can make by joint piece and take apart easily.During swelling, contact surface fits tightly not corrosion, also is convenient to take apart.
Description of drawings
Fig. 1 is the scheme drawing of embodiment; Only draw among the figure electrical motor and elevator drum bonded assembly position.
Marginal data, 1-brake wheel, 2-brake wheel side expansion set, 3-overcoat, 4-bolt, 5-half a coupler, 6-half a coupler side expansion set.
The specific embodiment
As shown in Figure 1, a kind of employing swelling cover bonded assembly single rope winding hoist is made up of electrical motor and elevator drum, and both realize being connected with half a coupler 5 through brake wheel 1, and wherein, both connection modes adopt the expansion coupling sleeve connection mode.Expansion coupling sleeve comprises brake wheel side expansion set 2, half a coupler side expansion set 6 and overcoat 3, and overcoat 3 usefulness bolts 4 tighten up.
Claims (1)
1. single rope winding hoist that adopts swelling cover connection mode; Form by electrical motor and elevator drum; Electrical motor is realized being connected through brake wheel and half a coupler with elevator drum, it is characterized in that the connection mode of electrical motor and elevator drum adopts the expansion coupling sleeve connection mode.
