Abstract
The utility model relates to a running device for a bridge crane. The utility model is characterized in that a hydraulic coupler is installed between a speed reducer and a motor, and the wheels of a wheel system are in tapered keyless connections with a wheel shaft. The utility model can realize running with low vibrations and low noise, and stable speed reduction and braking without impact; the utility model can guarantee the normal running of the motor, has simple structure, and can reduce energy consumption.
Description
The utility model relates to a kind of steady, the cart running gear of crane in bridge type of braking.
The cart running gear of crane in bridge type of the prior art, no matter be the centralized driving form or drive form respectively, the starting situation of the electrical motor of its kinematic mechanism is divided into two kinds: a kind of is not have the preparation blocked resistance, i.e. electrical motor one energising, and transmission device promptly has the moment of starting effect; Another kind has the preparation blocked resistance, i.e. produce the moment less than mechanism's static resistance square during electrical motor energising earlier, the unstart still of mechanism's this moment, but eliminated drive gap and given driving system with predetermincd tension, its dynamic loading is less.Because two kinds of mode of motion all are electrical motor direct drive operating mechanisms, to start not steadily, effect is undesirable.
Existed in the prior art on the electric block transfer crane operating unit and adopted hydraulic coupler, making kinematic mechanism realize not having impacts, the technology that steadily rises, brakes, but it adopts is the operating unit that Wheeling System suit upper reducer, drg, hydraulic coupler and motor drive mechanism at the dihedral bearing block support constitute, and this structure is not suitable for using on crane in bridge type.
The purpose of this utility model is to provide a kind of crane in bridge type that is used for, and had, braked steadily, no impact, and simple in structure, installation and maintenance are running gear easily.
Above-mentioned purpose of the present utility model is to realize that by such technical scheme promptly the utility model comprises end carriage, Wheeling System, the gear shaft coupling of connection Wheeling System and retarder slow-speed shaft, retarder, fluid power pusher brake and electrical motor; Of the present utility modelly be characterised in that boring is shaped on bearing saddle bore on the end carriage, the wheel shaft of Wheeling System matches with bearing saddle bore; The high speed shaft of retarder is connected with motor reel by the hydraulic coupler of band brake wheel.
Said structure of the present utility model can further specify by accompanying drawing.
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is the utility model wheel assembly drowing.
Referring to accompanying drawing: crane in bridge type running gear described in the utility model comprises: boring is shaped on the end carriage 1 of bearing saddle bore, the Wheeling System 2 that matches with bearing saddle bore, the gear shaft coupling 3 that connects Wheeling System and retarder slow-speed shaft, retarder 4, fluid power pusher brake 5, the hydraulic coupler 6 that connects the band brake wheel of retarder high speed shaft and motor reel, electrical motor 7.
In an embodiment of the present utility model, crane in bridge type adopts four girder constructions, and Wheeling System adopts tapering as shown in Figure 2 keyless.Be that tapered axial is through in the taper hole of wheel, with lining 11, antifriction-bearing box 10, hold-down ring 9 and push bolt 8 closely cooperate wheel shaft and wheel.
Working process of the present utility model is such: promptly when electrical motor is switched on, fluid power pusher brake 5 is opened, because acting on of hydraulic coupler every carrying, make the electrical motor starting under no load, drive hydraulic oil by its pump impeller, drive turbo driving, drive retarder by turbine again, gear coupling and Wheeling System do not have the smooth starting of the ground of impact.
The utility model is owing to adopted said structure, and its effect that reaches is very significant, and following several aspect is specifically arranged:
One, owing to take first motor and coupling device reverse rotating brake, waits cart motion speed Degree motion mode of fluid power pusher brake braking again close to zero time has been realized flat Steady shock-free retarding braking.
Two, owing to adopted fluid-flywheel clutch, motor can adopt cage modle YZ or Y System row motor without start resistor and complicated start-control device, improves The reliability used of device, also simplify the structure.
Three, when wheel movement system jam overload, because the overload protective function of hydraulic coupler, make still normal operation and not being damaged of electrical motor.
Four, since the characteristic curve of electrical motor and impeller disk associating than electrical motor physical feature " hardness is little ", rotating speed is responsive with load change, so good from tonality after the starter motion deflection, particularly dolly is by end, when the cart wheel load is differed greatly, be not prone to deflection yet.
Five, low vibration low noise motion, the energy consumption of having saved starting current have been realized.
Six, because the boring system of employing end carriage helps crane in bridge type Quantity production, adopt the keyless Wheeling System of tapering, help the I﹠M of Wheeling System; Simultaneously, reduce workpiece, increased gauge member, outsourcing piece, thereby be convenient to produce with respect to original structure.
