Description
Technical field
The utility model relates to the concrete mixer field, in particular to a kind of pivoting support lubrication system and concrete mixer.
Background technique
The residing operating mode of concrete pump truck arm pivoting support is a kind of low speed, heavy condition, and the environment polluted in rainwater, concrete for a long time needs often pivoting support to be carried out to injecting grease for lubricating.
The inner ring of pivoting support is arranged on the flanged plate on the pump truck underframe, and outer ring and turntable link together, and due to the pivoting support structure, the oil filling point of pivoting support all designs on the inwall of inner ring.
When pivoting support is arranged on pump truck, the lubrication hole that pivoting support carries all in a sealing, in the space that is not easy to arrive.Be lubricated and can only go out pivoting support by several extension pipe pass of transferring pivoting support, from outside, grease up is lubricated one by one.
The pivoting support of current domestic various brands pump truck all adopts this conventional lubrication mode, only a few point in the whole lubrication holes of pivoting support is realized by manual greasing.This lubricating system is incomplete lubricated to pivoting support, be prone to the grease up amount not, lubricating grease piles up and causes friction pair heat radiation difficulty and impaired, and because of the lubrication hole position too disperse, hidden, the maintainer often is difficult to arrive and leaks and add oiling agent, thereby increases the weight of the kinematic pair wearing and tearing.
As depicted in figs. 1 and 2, the outer ring 11 of pivoting support 10 is bolted on the flanged plate 21a of the underframe cylinder 21 that is fixedly installed on underframe 20, and inner ring 12 is connected with turntable.Lubrication hole on inner ring 12 inwalls of pivoting support 10, all in a sealing, in the space that is not easy to arrive, be lubricated and can only draw pivoting support 10 by switching high-pressure rubber pipe 30 pivoting support 10, is lubricated from outside grease up.
As shown in Figure 2, in prior art, on the underframe cylinder 21 at underframe 20, be designed with the few grease nipple mounting hole 21b of quantity, on the underframe cylinder 21 of the underframe 20 that grease nipple is installed, then the lubrication hole connected one to one to pivoting support 10 by high-pressure rubber pipe 30.
In fact pivoting support 10 can access the seldom part that lubricated point only accounts for its design lubrication hole quantity, and when grease up, is toward each grease nipple the inside, to buy oil one by one, and whether really complex operation can't judge lubricating grease lubricated putting in place.
Generally speaking, there is following shortcoming in prior art:
One, due to the underframe cylindrical structure, position and quantity that the grease nipple mounting hole on the underframe cylinder can be arranged all are restricted, and the lubricating system of this form can only provide lubricating grease to a small amount of several points in pivoting support.Pivoting support raceway length is larger, and lubricated only have wherein very short one section, easily cause the friction pair dry grinding;
During two, toward revolution supporting the inside injecting grease for lubricating, lubricating grease flows after a segment distance in orbit, because pressure reduces to cause the lubricating grease property variation that flows, causes lubricating grease can not get through.If continue by force greasing, overflow in the place that lubricating grease can be little from the pivoting support resistance, not lubricated to track and rolling element;
Three, because the single-point adopted disperses injecting grease for lubricating, can be one by one when operator buy oil to the each point oiling, inefficiency, and leak and add oiling agent because the lubrication hole position is too hidden.Some filling-up areas present position accessibility is poor, has potential safety hazard when personnel approach.
