Winch has the biggest lifting compared with hoist engine in terms of safety and uses for many years in mine engineering, but the oblique Construction of Silo in power station makes common winch be difficult to directly use in the oblique Construction of Silo in power station because its space limits.Nowadays the oblique Construction of Silo in power station has started to use single-drum winch, but the oblique Construction of Silo in power station makes single-drum winch sometimes install limited because construction space is limited.It is in particular in following several respects:
(1) common winch motor, decelerator, reel are arranged on same straight line, take up space and are difficult to greatly in hydro arrange.
(2) common winch operating system is complex.
(3) the oblique Construction of Silo in power station need to install two single-drum winches according to code requirement, require that installing separate unit winch possesses the mode of operations such as per-unit synchronous double traction, Remotes, being limited two difficulties of mounting arrangements by underground chamber space, two unit gearing traction synchronization accuracies simultaneously are poor in addition.
(4) the oblique Construction of Silo in power station there are requirements at the higher level to stability when winch safety, reliability and work.
Utility model content
The purpose of this utility model is to provide a kind of hoisting gear in the oblique Construction of Silo in power station, thus decreases the width of complete machine, saves space, the feature that during the oblique Construction of Silo in suitable water power station, winch arrangement space in hole is limited.
The technical solution of the utility model is: a kind of hoisting gear in the oblique Construction of Silo in power station includes main shaft device, disk brake, gear coupling, decelerator, shaft coupling, electromotor brake, motor, main shaft device is connected with decelerator by gear coupling, decelerator is coupled with electromotor brake by shaft coupling, electromotor brake couples with motor again, two reels are had on main shaft device, in the upper and lower at two reel two ends equipped with four disk brakes, decelerator and main shaft device are 90 ° of layouts.
Described main shaft device holds the depth indicator being connected in opposite directions with decelerator.
Described main shaft device is two-fold barrel structure, and uses double traction electric control system, and reel uses 16Mn coiled sheet system to be welded, has the advantages that intensity is high, equivalent mass is little, and startup and the braking ability of winch are significantly improved.
Described disk brake uses rear-mounted disk brake; high-strength bolt can be crossed be connected on the reel of main shaft device; transmitting braking moment by big planar friction, disk brake has with reel and coordinates seam to make radially location, and disk brake is provided with brake clearance protection.
Described shaft coupling uses elastic plug tooth-type coupler.
Hoisting gear in the oblique Construction of Silo in power station of the present utility model uses 90 ° of layouts, decreases the width of complete machine, saves space, is suitable for the construction of the oblique vertical shaft of hydropower industry；Between motor and decelerator, it is provided with electromotor brake simultaneously, effectively changes hoisting gear and start and braking moment, the impact to decelerator formed because of motor inertia.Disk brake is provided with brake clearance protection, can report to the police when brake clearance exceedes setting and complete can not start shooting after this promotes；Use rear-mounted disk brake, pollution to brake disc when effectively changing disk brake leakage of oil, thus ensure that stationarity and security reliability when hoisting gear is braked.Main shaft device uses double-cylinder type, and uses double traction electric control system, meets the double traction control of per-unit synchronous.
Hoisting gear unit operation power-balance in the oblique Construction of Silo in power station of the present utility model, double hauling speed Complete Synchronization, accurate positioning, good stability, reliability is high；Human oriented design, simple to operate, debugging maintenance is convenient, takes up room little.
Accompanying drawing explanation
Fig. 1 is the structural representation of the hoisting gear in the oblique Construction of Silo in power station of the present utility model.
In figure: 1 depth indicator, 2 disk brakes, 3 main shaft devices, 4 gear couplings, 5 decelerators, 6 shaft couplings, 7 electromotor brakes, 8 motor.
Detailed description of the invention
As shown in Figure 1, hoisting gear in the oblique Construction of Silo in power station of the present utility model includes main shaft device 3, disk brake 2, gear coupling 4, decelerator 5, shaft coupling 6, electromotor brake 7, motor 8, main shaft device 3 is connected with decelerator 5 by gear coupling 4, decelerator 5 uses elastic plug tooth-type coupler by shaft coupling 6() couple with electromotor brake 7, electromotor brake 7 couples with motor 8 again, two reels are had on main shaft device, in the upper and lower at two reel two ends equipped with four disk brakes 2, decelerator 5 and main shaft device 3 are 90 ° of layouts.
Described main shaft device 3 holds the depth indicator 1 being connected in opposite directions with decelerator 5.
The two-fold barrel structure of described main shaft device uses double traction electric control system, and reel uses 16Mn coiled sheet system to be welded, has the advantages that intensity is high, equivalent mass is little, and startup and the braking ability of winch are significantly improved.
