Description
Technical field
The utility model relates to a kind of spiral case doors to pass in and out special staircase, belong to spiral case door service technique field.
Background technique
Circular diameter reaches 2m or more from inner circle minimum point to spiral case distance from bottom less than 0.7m in Power Station Turbine spiral case door,
Ordinary people not only exists by more difficulty and falls risk, but also reduce efficiency.Carry out the service work inside spiral case every time, into
This is the test to staff out.The prior art (or is moved from other places using iron wire binding Wooden stair
Stair) for disengaging, but bind time-consuming and laborious expense material and Wooden stair is easily damaged, it is unstable in addition to bind that there is also structures
Fixed, insecure problem.So needing the reliable tool of one kind to improve safety of the staff by this when
And efficiency.
Utility model content
Technical problem to be solved by the utility model is: providing a kind of spiral case door disengaging special staircase, have structure simple,
It is easy for installation, it is reliable and stable the advantages that, with overcome the deficiencies in the prior art.
The technical solution of the utility model is: a kind of spiral case door disengaging special staircase, including spiral case door and stair, in stair
Rotation is socketed with 2 connecting rods on the cross bar of upper end, and 2 connecting rods are detachably connected on respectively in the two side walls of spiral case door.
Connecting rod one end is socketed on the cross bar of stair upper end by sleeve rotation, and the other end is arranged in the on connector
In one installing pipe, the connection bar part on the outside of the first installing pipe is equipped with external screw thread, limits with nut cooperation to connecting rod, even
There is the second installing pipe, the second installing pipe is fixed in the screw hole of spiral case door two sides by screw on fitting.
First installing pipe is identical with the hollow axial direction of the second installing pipe.
First installing pipe and the second installing pipe are stainless steel tube, and the two passes through welded connecting.
Stair material is stainless steel material.
The utility model has the beneficial effects that the utility model makes full use of original screw hole on spiral case door, set on stair
Rotatable connecting rod is counted, and connecting rod and the screw hole on spiral case door are detachably connected, designed special staircase has knot
The advantages that structure is simple, easy for installation, reliable and stable, practical, long service life makes particularly suitable for spiral case maintenance
With.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is partial enlargement diagram at the B in Fig. 1；
Description of symbols: 1 vertical pole, 2 cross bars, 3 connecting rods, 4 first installing pipes, 5 nuts, 6 second installing pipes, 7 spiral cases
Door, 8 screws, 9 sleeves.
Specific embodiment
With reference to the accompanying drawing and utility model is described further in specific embodiment:
With reference to Fig. 1 and Fig. 2, special staircase, including spiral case door 7 and stair are passed in and out according to a kind of spiral case door of the utility model,
There are multiple screw holes, stair are existing conventional stair, are mainly connected to by 2 vertical poles 1 and several on existing 7 wall surface of spiral case door
Cross bar 2 between two vertical poles 1 forms, and rotation is socketed with 2 connecting rods, 3,2 connecting rods 3 and divides on the cross bar 2 of stair upper end
It is not detachably connected in the two side walls of spiral case door 1, which constitutes the core component of the utility model, working principle
It is: is detachably connected on stair in the screw hole in the two side walls of spiral case door 7 i.e. by rotatable connecting rod 3 when use
It can.
Specifically, 3 one end of connecting rod and 9 outside wall surface of sleeve are rigidly connected, and sleeve 9 rotates the cross bar for being socketed in stair upper end
On 2,3 other end of connecting rod is arranged in the first installing pipe 4 on connector, positioned at connecting rod 3 of 4 outside of the first installing pipe
It is arranged with external screw thread, connecting rod 3 is limited with the cooperation of nut 5, so when stair rely on spiral case door 1, nut 5 can be real
Now to effective support of stair.There is the second installing pipe 6, the second installing pipe 6 is fixed on spiral case door 1 by screw 8 on connector
In the screw hole of two sides, that is, screw 8 is arranged in the second installing pipe 6 when installing, and is realized tightly with the screw hole cooperation on spiral case door 1
It is solidly connected.
In order to improve service life, the first installing pipe 4, the second installing pipe 6 and the preferred stainless steel material of stair material, wherein
First installing pipe 4 and the second installing pipe 6 are preferably stainless steel tube, and the two makes its hollow axial direction phase by being welded to connect
Together, in order to installing.
It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined
Assert that the specific implementation of the utility model is only limited to these instructions.For the ordinary skill of the utility model technical field
For personnel, without departing from the concept of the premise utility, a number of simple deductions or replacements can also be made, should all regard
To belong to the protection scope of the utility model.
