Description
Technical field
The utility model relates to a kind of bracing or strutting arrangement, specifically, relates to a kind of concrete mixer truck ring raceway assembly with lubricating arrangement.
Background technology
Concrete mixer truck is used for transporting the specialized truck of build concrete; Due to its profile, be also often called as river snail car.On this class truck, all install the mixing drum of cylinder type to deliver mixed concrete.In transportation, can remain that mixing drum rotates, the concrete being delivered to ensure can not solidify.Transport after concrete, conventionally all can rinse mixing drum inside for water, prevented that the concrete of sclerosis from taking up room, made the volume of mixing drum fewer and feweri.
Concrete mixer truck is made up of parts such as automobile chassis, mixing drum, transmission system, water supply installation, Full-power takeoff, mixing drum front and back support, reductor, Hydraulic Power Transmission System, discharging system, operating mechanisms.
Concrete mixer truck operation principle is: by power takeoff, the power of automobile chassis is taken out, and the variable pump of drive hydraulic system principle, mechanical energy being converted into hydraulic energy and passing to fixed displacement motor, motor drives reductor again, drive agitating device by reductor, concrete is stirred.
The effect of power takeoff is by handling power taking switch, engine power to be taken out, drive mixing drum through hydraulic system, beater cylinder is rotated in the forward in charging and transportation, be beneficial to charging and concrete is stirred, in the time of discharging, counter-rotate, after work termination, cut off and connect with the power of engine.
Hydraulic system is by the engine power taking out through power takeoff (being all generally rearmounted global function power takeoff), be converted into hydraulic energy (discharge capacity and pressure), be output as mechanical energy (rotating speed and moment of torsion) through motor again, provide power for mixing drum rotates.
Reductor is passed to mixing drum after the rotating speed of motor output in hydraulic system is slowed down.
Operating mechanism control mixing drum direction of rotation, makes it to be rotated in the forward in charging and transportation, when discharging, counter-rotates; Control the rotating speed of mixing drum
The Main Function of purging system is to clean mixing drum, sometimes also for carrying out in transit siccative stirring.Purging system also plays cooling effect to hydraulic system.
Whole closing appliance adopts rotary sealing technology, has sealed the feed inlet and outlet of trucd mixer, has solved traditional trucd mixer water evaporates, the series of problems such as mortar laminated, concrete material scatters, traffic safety.
It is mainly made up of agitating device mixing drum and supplemental support parts thereof.Mixing drum is concrete container, and it is to be made up of the wear-resisting sheet metal of high-quality, and for loading, unloading concrete automatically, its inwall is welded with the helical blade of special shape.When rotation, concrete moves along the hand of spiral of blade, is mixed and stir in constantly promoting and stirring process.In charging and transportation, mixing drum forward, concrete moves inwards along blade, when discharging, mixing drum reversion, concrete outwards draws off along blade.The rotation of mixing drum is to ensure by fluid pressure drive device.
The rotation direction of when filling with substance beater cylinder is forward rotation, and the rotation of vehicle in transportation is also forward rotation; Vehicle is at when filling with substance, and driven by engine beater cylinder rotates, and speed is 6-10 rev/min; Concrete draws off through the discharge port of mixer, enters mixing drum by charging system from nozzle conduit, and under helical blade guiding, flows to the middle and lower part of mixing drum.To adding the ready-mixed concrete of mixing drum, the low speed " forward " that only need make in transit 1-3r/min rotates, and now concrete is only subject to slight disturbance, to keep concrete homogeneous, prevents segregation simultaneously.
Beater cylinder middle part arranges ring raceway; On beater cylinder support, be provided with supporting rollern and also claim support roller; The supporting rollern of beater cylinder support both sides contacts with ring raceway.Support roller and ring raceway are rolling friction, due to insufficient lubrication, support roller occurs that wearing and tearing may cause support roller surface to occur groove, and gash depth is with deepening service time, general gash depth exceedes 2mm, need to have more the concrete mixer truck ring raceway assembly of lubricating arrangement.
Utility model content
For above-mentioned deficiency of the prior art, it is a kind of simple in structure that the utility model provides, and reduces support roller wearing and tearing, improves the support roller concrete mixer truck ring raceway assembly with lubricating arrangement in service life.
Technical solution adopted in the utility model is:
There is a concrete mixer truck ring raceway assembly for lubricating arrangement, comprise the ring raceway that is arranged on beater cylinder middle part; The below of ring raceway is respectively arranged with support roller along the beater cylinder axis left and right sides, and support roller contacts with ring raceway; Support roller is arranged on roller bracket, and roller bracket is bolted on beater cylinder support, and described ring raceway circumferential surface has been disposed radially annular groove, and support roller inserts in annular groove; Annular groove bottom sides is provided with the grease groove extending to ring raceway entity; Described annular groove is U-shaped groove; Described annular groove width is 6-10 centimetre; Support roller width is 4-8 centimetre.
The beneficial effect of the relative prior art of the utility model:
The concrete mixer truck ring raceway assembly that the utlity model has lubricating arrangement, described ring raceway circumferential surface has been disposed radially annular groove, and support roller inserts in annular groove; Annular groove bottom sides is provided with the grease groove extending to ring raceway entity; In annular groove, can store more lubricant grease and reduce support roller wearing and tearing, improve support roller service life, reduce concrete mixer truck maintenance cost; Simultaneously annular groove can play location, cushioning effect to beater cylinder, reduces the concrete mixer truck middle swing amplitude of travelling, and plays the effect of protecting transmission system.
