Description
Technical field
The utility model is related to a kind of detachable water wheel machine overhauling stair, belong to hydraulic turbine repair apparatus technical field.
Background technology
When existing water wheels machine overhauling, need the manually guard rail climbing above water dispenser machine to water-turbine top cover, than
Relatively time consuming laborious, safety is poor, directly carries and sets up stair, time-consuming and laborious, and turbine chamber movable stair is inconvenient.
Invention content
The technical problems to be solved in the utility model is：A kind of detachable water wheel machine overhauling stair are provided, can realize province
Shi Shengli, it is safe, movable stair is avoided, to solve problems of the prior art.
The technical solution that the utility model is taken is：A kind of detachable water wheel machine overhauling stair, include the stair of fluking type
Ontology, stair ontology upper end are removably connected on the guard rail at the top of the hydraulic turbine, and lower end extends to hydraulic turbine top
At lid and it is fitted at hydraulic turbine wall.
Preferably, above-mentioned stair ontology upper end hook portion free end passes through through-hole on the middle part cross bar of guard rail and penetrates into
In blind hole, blind hole is using steel-pipe welding in the support platform of guard rail.
Preferably, both ends are removably connected to protective fence at the middle part cross bar of above-mentioned connection stair ontology upper end hook portion
On bar.
The beneficial effects of the utility model：Compared with prior art, the utility model is by dismountable fluking type stair,
Hang upside down on protective fence, manually from protective fence installation stair under to being overhauled on hydraulic turbine cover, realize time saving
Laborsaving, safety greatly improves, and avoids movable stair, and dismountable stair can realize picking and placeing for stair, fit to wall
At wall, occupied space is reduced, hang avoids stair from contacting the hydraulic turbine, improves the safety in utilization of stair, the utility model
Also have the characteristics that simple in structure, at low cost, easy to loading and unloading quick.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the left view structural representation of Fig. 1.
Specific implementation mode
Below in conjunction with the accompanying drawings and the utility model is described further in specific embodiment.
Embodiment：As Figure 1-Figure 2, a kind of detachable water wheel machine overhauling stair, include the stair ontology 1 of fluking type,
1 upper end of stair ontology is removably connected on the guard rail 2 at the top of the hydraulic turbine, and lower end extends at water-turbine top cover simultaneously
It is fitted at hydraulic turbine wall, guard rail 2 is loop configuration, is fixedly connected in support platform.
Preferably, 1 upper end hook portion free end of above-mentioned stair ontology passes through through-hole on the middle part cross bar 3 of guard rail 2 and wears
Enter into blind hole 4, for blind hole 4 using steel-pipe welding in the support platform 5 of guard rail 2, mounting is reliable and stable.
Preferably, both ends are removably connected to protection at the middle part cross bar 3 of above-mentioned 1 upper end hook portion of connection stair ontology
On railing 2, sleeve 6 is arranged in both ends at middle part cross bar 3, and is supported using support chip 7, and sleeve 6 is embedded just below right to middle part cross bar 3
Place should be held, position-limiting action is played.
Above description is only a specific implementation of the present invention, but the scope of protection of the utility model is not limited to
In this, any one skilled in the art within the technical scope disclosed by the utility model, can readily occur in variation
Or replace, it should be covered within the scope of the utility model, therefore, the scope of protection of the utility model should be with the power
Subject to the protection domain that profit requires.
