Abstract
The utility model relates to a silt and impurity removal auxiliary device for hydraulic excavator fuel tank, which is composed of a fuel tank (1), a bottom surface flange (2), a bottom cover component (3), a pipe joint (4), an oil discharge valve (5), an O-shaped seal ring (6) and a hexagonal head bolt (7); wherein, a through hole is correspondingly machined on the bottom of the fuel tank (1) and is welded with the bottom surface flange (2), a silt discharge groove is machined on the bottom surface flange (2); a seal ring annular groove is machined on the bottom cover component (3); meanwhile, a through hole is machined on the bottom cover component (3) and is welded with the pipe joint (4) of the oil discharge valve (5), the oil discharge valve (5) is screwed on the pipe joint (4) of the bottom cover component (3), the bottom cover component (3) is matched with the O-shaped seal ring (6) to be mounted on the flange on the bottom of the fuel tank (1) through the hexagonal head bolt (7). The silt and impurity removal auxiliary device can effectively discharge silt in the fuel tank, prevent oil leakage and can be disassembled and assembled conveniently for washing the inner surface of fuel tank.
Description
Technical field
The utility model relates to a kind of hydraulic crawler excavator fuel tank row silt removal of impurities servicing unit, when the alluvial in the user need discharge the fuel oil casing is dirty, and can be by opening fuel outlet valve or dismounting bottom assembly, removing easily and effectively.
Background technology
At present, both at home and abroad the auxiliary row of the hydraulic crawler excavator fuel tank of producing become silted up knot screen now mostly are unions of the single fuel outlet valve of burn-oning in the oil box bottom, the fuel outlet valve of screwing on gets final product.The user will discharge the retained foreign body in the fuel oil casing, and the fuel outlet valve of opening that can only be single discharges.Because the fuel outlet valve opening is little, the fuel oil casing uses the back easily to stop up for a long time; In addition, fuel tank inner surface when producing needs phosphatization to handle, because it is little and welded fixingly with fuel tank that the union opening of fuel outlet valve is installed, cleans fuel oil interior inconvenience, makes troubles to production operation.
Summary of the invention
The purpose of this utility model is to provide a kind of fuel oil casing is removed the retained foreign body difficulty after producing cleaning and using certain hour method that solves, can reliably remove residual dirt in the fuel oil casing easily, reduce the time that the oil box phosphatization is cleaned, enhance productivity.The internal thread hole of fuel outlet valve generally adopts the gas thread of G1/2 in actual use, and is just relative a little bit smaller with the union endoporus of G1/2 gas thread coupling.Even some producer neither wise selection for the internal thread hole that strengthens fuel outlet valve, because, on the one hand, the size of internal thread hole yardstick should adapt to the fuel tank size of excavator at appearance proportion, and the fuel outlet valve of too big internal thread and fuel tank coupling can influence outward appearance; On the other hand, strengthen inner hole thread and just mean that the fuel outlet valve monnolithic case strengthens, this processing cost in fuel outlet valve is unfavorable.For gas thread is the G1/2 or the fuel outlet valve of some standards greatly, with the internal diameter of pipe joint of its coupling generally about 15mm, so little hole internal diameter phosphatization is cleaned and is inconvenient, and the time of cleaning fluid discharge is restricted, and the impurity that produces during cleaning also is difficult for emitting from little hole like this.Just clean for convenience and must strengthen the floss hole diameter of oil box, and consider that the size of fuel outlet valve can not be excessive, just must have a changeover portion to connect the fuel outlet valve of large diameter floss hole to little endoporus.
Technical solution of the present utility model is such, comprises fuel tank, bottom surface flange, bottom assembly, fuel outlet valve.Be characterised in that the fuel tank bottom is equipped with the bottom surface flange, the bottom assembly is installed in flange bottom surface, bottom surface, bottom assembly bottom surface mounting pipe joint, and the union bottom surface connects fuel outlet valve.
Between fuel tank and the bottom surface flange through hole is arranged, between bottom assembly and the bottom surface flange through hole is arranged, between union and the bottom assembly through hole is arranged, have through hole to communicate between union and the fuel outlet valve.
The bottom surface flange has through hole and groove, threaded mounting hole.
The row's of the utility model has the advantages that silt removal of impurities servicing unit makes full use of the existing structure of fuel outlet valve, strengthens the impurity floss hole by the bottom surface flange, connects fuel outlet valve by bottom, need not too much spatial transition and just can conveniently connect, install; But bottom surface flange, bottom assembly separate machined, technology is easy, and cost is low, makes full use of the usefull space of structural member.Have simple in structure, safe and reliable in conjunction with closely, produce and clean conveniently, the user such as can optionally install and remove easily at advantage.
Description of drawings
It is such that structure of the present utility model constitutes:
Fig. 1 looks partial sectional view for fuel tank row silt removal of impurities servicing unit master of the present utility model.
Fig. 2 is that the A of Fig. 1 of the present utility model is to view.
Fig. 3 is the A-A sectional view of Fig. 1 of the present utility model.
Among Fig. 1～Fig. 3: fuel tank (1), bottom surface flange (2), bottom assembly (3), union (4), fuel outlet valve (5), O RunddichtringO (6), hexagon-headed bolt (7), groove (8), threaded mounting hole (9).
The specific embodiment
Most preferred embodiment of the present utility model is such: with reference to Fig. 1～Fig. 3, open the hole with welding bottom surface flange (2) in relevant position, fuel tank (1) bottom, lead to the hole site is decided on fuel tank (1) appearance and size, and the size in aperture can be greatly more best than fist; The hole is opened at bottom surface flange (2) center, the aperture is big as far as possible, greatly more best than fist, so can stretch out one's hand when produce cleaning and clean inner surface in fuel tank (1) body, the screwed hole that the thickness of bottom surface flange (2) should be enough to bore certain-length is with installation hexagon-headed bolt (7), and its degree of depth that enters fuel tank (1) should guarantee weld strength, unsuitable too short, the bottom surface flange (2) of Fig. 1, Fig. 2 is deep into fuel tank (1) inside, and bottom surface flange (2) row of having silt groove makes things convenient for the impurity discharging simultaneously; Bottom assembly (3) is drilled with installs through hole to be fixed on the bottom surface flange (2) with hexagon-headed bolt (7), open eyelet welding union nipple (4) with discharge impurities be connected fuel outlet valve (5), open the O RunddichtringO (6) that cannelure seals with installation; Fuel outlet valve (5) is tightened on the union of bottom assembly (3).
Fuel tank (1) can be processed bottom surface flange (2), bottom assembly (3) separately in process of production, and bottom surface flange (2) is welded on the fuel tank (1), and the staff can be by the convenient inner surface that cleans of the through hole of bottom surface flange (2) when phosphatization was cleaned fuel tank (1); The user uses fuel tank after (1) a period of time, wants to clear up the impurity in the casing, at first can pass through the switch discharge impurities of fuel outlet valve (5), secondly still can disassemble bottom assembly (3) and clean, thoroughly discharge impurities.
