Abstract
The utility model discloses a rear suspension limiting device for an electric-wheeled mining dumper, which belongs to the field of mining dumpers and comprises a rear axle and a limiting device. The limiting device comprises a limiting block, a transverse plate and a side plate, the limiting block is mounted on the transverse plate which is fixed onto the side plate, and the limiting device is fixed outside the rear axle. The rear suspension limiting device for the electric-wheeled mining dumper has the advantages that an oil cylinder can be protected and reliability of the limiting device is improved under severe pavement conditions, and the rear suspension limiting device is easy in mounting and higher in bearing capacity.
Description
Technical field
The utility model relates to a kind of quarry tipper product, relates in particular to a kind of back suspending position limit device of electric drive wheel quarry tipper, belongs to the quarry tipper field.
Background technology
At present, outside inhibiting device or the inhibiting device of hanging oil cylinder not being installed on the external large-tonnage electric drive wheel quarry tipper only are installed in hanging oil cylinder inside.Common oleo-pneumatic suspension is sealed in fluid and gas in the oil cylinder fully, in case occur revealing, fluid and gas can't compensate, if this moment, the road surface was ill-conditioned, oil cylinder piston will clash into cylinder body, causes damage.Common way is at hanging oil cylinder set inside fender guard, prevents that oil gas from revealing the piston cause and the collision of cylinder body.But thisly install the comparison difficulty, and a little less than the load-carrying capacity, reliability is low at hanging oil cylinder set inside fender guard.
Summary of the invention
Problem to above-mentioned prior art existence; The utility model provides a kind of back suspending position limit device of electric drive wheel quarry tipper, have under the ill-conditioned situation in road surface, can protect oil cylinder, improve the inhibiting device reliability, install easily, effect that load-carrying capacity is stronger.
To achieve these goals; The technical scheme that the utility model adopts is: a kind of back suspending position limit device of electric drive wheel quarry tipper; Comprise back axle and inhibiting device, inhibiting device comprises limiting stopper, transverse slat and side plate, and limiting stopper is installed on the transverse slat; Transverse slat is fixed on the side plate, and inhibiting device is fixed on the outside of back axle.
Inhibiting device has two, and symmetry is fixed on the both sides of back axle respectively.
Side plate on the inhibiting device is fixed on the outside of back axle through welding manner.
Transverse slat is provided with four tapped bore, to four circular holes should be arranged, with screw limiting stopper is fixed on the transverse slat on the limiting stopper.
The limiting stopper material is a nylon.
The upper surface of limiting stopper is parallel with the bottom surface of frame beam.
The beneficial effect of the utility model is: under the ill-conditioned situation in road surface, can protect oil cylinder, improve the inhibiting device reliability, install easily, load-carrying capacity is stronger.
Description of drawings
Fig. 1 is installed in the scheme drawing under the frame beam for back axle;
Fig. 2 is installed in the scheme drawing on the back axle for the inhibiting device of the utility model;
Fig. 3 is the inhibiting device structural representation of the utility model.
Among the figure: 1, limiting stopper, 2, transverse slat, 3, side plate, 4, back axle, 5, frame beam, 6, suspension.
The specific embodiment
To combine accompanying drawing that the utility model is described further below.
Like Fig. 1, Fig. 2 and shown in Figure 3, the utility model comprises back axle 4 and inhibiting device, and inhibiting device comprises limiting stopper 1, transverse slat 2 and side plate 3, and limiting stopper 1 is installed on the transverse slat 2, and transverse slat 2 is fixed on the side plate 3, and inhibiting device is fixed on the outside of back axle 4; Inhibiting device has two, and symmetry is fixed on the both sides of back axle 4 respectively; Side plate 3 on the inhibiting device is fixed on the outside of back axle 4 through welding manner; Transverse slat 2 is provided with four tapped bore, to four circular holes should be arranged, with screw limiting stopper 1 is fixed on the transverse slat 2 on the limiting stopper 1; Limiting stopper 1 material is a nylon; The upper surface of limiting stopper 1 is parallel with the bottom surface of frame beam 5.
The utility model is welded in the limiting stopper base on the back axle 4 through side plate 3, and the position of weld of two inhibiting device symmetry guarantees that frame beam 5 just in time covers limiting stopper 1 fully, and is approximate parallel with frame beam 5 bottom surfaces above the limiting stopper 1.At hanging oil cylinder set inside fender guard, prevent that oil gas from revealing the piston cause and the collision of cylinder body.But in order to improve the reliability of device, at the outer setting limiting stopper of hanging oil cylinder.This texture ratio is realized at hanging oil cylinder set inside stop gear more easily, and load-carrying capacity is stronger, and reliability is higher.Under the situation that oleo-pneumatic suspension 6 is not revealed, even oleo-pneumatic suspension 6 reaches range, frame beam 5 also is discontiguous with limiting stopper 1; Reveal in case oil gas takes place oleo-pneumatic suspension 6; Bump with hanging oil cylinder might take place in piston, and before piston bumped against oil cylinder, frame beam 5 had contacted with nylon limiting stopper 1; Nylon has certain amount of compression; The effectively power and the vibration of buffering collision of closed generation can guarantee that through rational design and calculating nylon limiting stopper 1 reaches maximum compressibility, and the piston of oleo-pneumatic suspension 6 can not clash into oil cylinder yet.
