Meanwhile constructing the application method of soft climbing ladder apparatus the invention also discloses a kind of inclined shaft steel pipe inner wall, feature exists
In the application method the following steps are included:
Step 1: searching the steel pipe lifting lug of inclined shaft steel pipe upper end: being checked to inclined shaft steel pipe upper end tube nozzle, work as inclined shaft
Lifting lug connecting plate is arranged there are when steel pipe lifting lug in steel pipe upper end in two rack cross-bars on the rack cross-bar of upside,
Then, step 2 is executed；When steel pipe lifting lug is not present in inclined shaft steel pipe upper end, step 2 is executed；
Step 2: the first connection for saving soft ladder segment and ladder fixed bracket and ladder fixed hook: the company of utilizing outside well
The fixed bracket of ladder is fixedly connected by connecting bolt with ladder fixed hook, and head is saved in the soft ladder segment in multiple foot pedals
Foot pedal positioned at top is installed in the hook of ladder lifting rod, and is sealed using the escapement on ladder lifting rod hook
Lock；
Step 3: the clamping of ladder fixed hook:
When inclined shaft steel pipe upper end is there are when steel pipe lifting lug, head is saved into the soft ladder segment and is stretched in inclined shaft steel pipe,
Lifting lug connecting plate and steel pipe lifting lug are cooperated, lifting lug connecting plate is fixedly connected by lifting lug clamping screw with steel pipe lifting lug, and is made
The clamping of ladder fixed hook is fixed on inclined shaft steel pipe top；
When steel pipe lifting lug is not present in inclined shaft steel pipe upper end, head is saved into the soft ladder segment and stretches to inclined shaft steel pipe
It is interior, and the clamping of ladder fixed hook is made to be fixed on inclined shaft steel pipe top；
Step 4: the non-first connection for saving soft ladder segment and its previous soft ladder segment of section: the non-first section soft ladder section
It is located at the foot pedal of top in section in multiple foot pedals and two segments on its previous soft ladder segment of section clamps part cooperation,
And the escapement on part is clamped using segment and is blocked；
It includes the activity branch hinge of fixed branch hinge and bottom end with hook that segment, which clamps part, and one end of fixed branch hinge is cut with scissors by branch
Connection pin shaft and the top that activity branch is cut with scissors are hinged, and the other end of fixed branch hinge is sleeved in soft ladder segment position in multiple foot pedals
In on the foot pedal of lowermost end, fixed branch hinge is located at most in multiple foot pedals by clamping in part clamping screw and soft ladder segment
The foot pedal of bottom end is fixedly connected；
According to practice of construction height, the quantity of soft ladder segment is determined, until soft ladder length meets construction requirement；
Step 5: installation safety rope: one end of safety rope being connect with snap ring, the other end and safety line of safety rope connect
Fitting two connects；
Step 6: construction personnel passes in and out inclined shaft steel pipe: construction personnel wears catching device, and catching device is mounted on safety rope
Follow the synchronous disengaging inclined shaft steel pipe of construction personnel；
Step 7: the non-first disassembly for saving soft ladder segment: after to be onstructed, being torn open to the non-first soft ladder segment of section
It unloads, the non-first soft ladder segment of section is dismantled according to sequence from the bottom to top, soft ladder segment is saved in non-head in disassembly personnel station
The soft ladder segment of previous section on, pull the anti-drop rod on the non-first soft ladder segment of previous section for saving soft ladder segment, anti-drop rod

Well steel pipe causes to damage, and without weld job, avoids the welding damage to steel pipe, is conducive to tube quality and finished product protection,
Reduce it is subsequent cut off polishing project amount, convenient for promote the use of.
2, on the one hand soft climbing ladder apparatus of the invention mounts soft ladder, and mount soft climb by the fixed bracket of setting ladder
Soft ladder is connect with the fixed bracket of ladder by escapement after ladder, high safety；On the other hand installation safety line connection
Part one connects safety rope, complete function；In addition, when inclined shaft steel pipe upper end is there are when steel pipe lifting lug, in two rack cross-bars
Lifting lug connecting plate is set on the rack cross-bar of upside, soft climb is strengthened by the connection of lifting lug connecting plate and steel pipe lifting lug
The firmness of ladder device improves degree of safety, reliable and stable, and using effect is good.
3, soft climbing ladder apparatus of the invention, soft ladder along inclined shaft length of steel pipe direction and from high to low successively head and the tail by more piece
The soft ladder segment composition of connection, the soft ladder segment of adjacent two clamp part by segment and connect, and each segment clamps on part
Same installation escapement, improves the connection reliability of soft ladder segment；In escapement using pull anti-drop rod so that drive
Stripper plate squeezes spring, so that the degree for making anti-drop rod block foot pedal gradually decreases, hand unclamps anti-drop rod, and spring returns automatically
Bullet, so that anti-drop rod is made to block foot pedal completely, it is easy to operate, the assembly between each components is reduced, is in inclined shaft steel pipe
The time is saved in construction.
4, method of the invention, step is simple, according to inclined shaft steel pipe actual conditions, adjusts ladder fixing rack structure, leads to
It crosses and connects the soft ladder segment of first section and the fixed bracket of ladder and ladder fixed hook on well, clamp ladder fixed hook, according to
Practice of construction height determines the quantity of soft ladder segment, and the non-first soft ladder segment of section and its previous soft ladder of section are completed in well
The connection of segment, installation is simple, while design safety cord attachment one and safety line connector two cooperate, connection safety
Rope when ensuring to occur accident when climbing rope ladder, has safeguard protection effect convenient for connection catching device；In addition, disassembly is non-in well
Head saves soft ladder segment, versatile without using the auxiliary construction of large scale equipment, is conducive to steel pipe finished product protection, and adjacent two
A soft ladder segment installing and dismounting is quick, can satisfy the different operating condition of the oblique straight section of steel pipe in slope construction, upper lower horizontal section
Needs.
In conclusion the present invention is novel in design rationally, by ladder fixed hook, the fixed bracket of ladder and more piece along inclined shaft
Matching relationship between length of steel pipe direction and the soft ladder segment being sequentially connected end to end from high to low with inclined shaft steel pipe inner wall, it is real
Existing construction personnel passes in and out inclined shaft steel pipe and avoids the welding damage to steel pipe without weld job, be conducive to tube quality and at
Product protection, reduce it is subsequent cut off polishing project amount, and can flexibly select soft ladder segment according to practical inclined shaft length of steel pipe
Quantity, two neighboring soft ladder segment installing and dismounting is quick, can satisfy the oblique straight section of steel pipe in slope construction, upper lower horizontal section
The needs of different operating condition, convenient for promoting the use of.
