Description
Technical field
This utility model is related to the realm of building construction, can particularly to a kind of turbine screw for hydraulic climbing die block system
The support meanss continuously adjusting.
Background technology
With the rapid development in city, in Urban Building Construction field, particularly high-rise and high-rise building
Core Walls Structure concrete placings construction in, hydraulic climbing shuttering system due to its high working efficiency, simple to operate, safety coefficient is high, to week
Enclose that environmental disturbances are few, construction cost low advantage more and more welcomed by the people, be applied in more and more engineering projects
Go.
At present, in high-rise and high-rise building Core Walls Structure concrete placings are constructed, built-in fitting, peace are buried in position in advance first
Dress wall-attaching equipment, inserts the track that climbs, finally installs whole support body and template.From start to finish, whole hydraulic climbing die block system from
Weight and service load all pass to wall-attaching equipment, because wall-attaching equipment is located at the inner side of hydraulic climbing die block system, hydraulic climbing die block system
Deadweight and service load will necessarily produce one very greatly around the moment of wall-attaching equipment, in order to balance this big moment, just must
Support meanss need be set up in the bottom of hydraulic climbing die block system, with core concrete height its wall thickness of change also constantly
Vary it is desirable to support meanss also and then change apart from the distance of metope.At present, conventional way has two kinds, and one kind is to prop up
The pin-and-hole of several corresponding different distance values is pre-designed on strut, distance is divided into several gears, according to practical situation, select
Different pin-and-hole insertion bearing pins, so can be only formed several limited discrete distance values it is impossible to form continuous range of accommodation；
Another is to replace support bar with screw rod, and rotary screw just can adjust screw rod extension elongation, thus realizing the nothing of support distances
Pole adjusts and to meet the practical situation needs of engineering project, because the angle that screw rod rotates every time is all not quite similar, so not side
Just in screw end head, the wheel rolling is installed, before the support body that climbs every time it is necessary under first being substituted with interim auxiliary jack
Support meanss, unclamp studdle, after support body climbs specified absolute altitude, again apply studdle, remove interim auxiliary
Jack, complete entirely to climb process.Therefore, the first way is discontinuously continuously adjusted it is impossible to meet engineering due to range of accommodation
The needs of section, are gradually eliminated；Although second way can continuously adjust in certain scope, climbing every time
When be to be required for arranging interim auxiliary jack, one building core tube construction get off, especially Super High, the super large scale of construction
Large building it may be necessary to repeat hundreds of time or even thousand of interim auxiliary jack are set, not only waste time and energy, shadow
Loud efficiency of climbing, increases human cost, and can produce the potential safety hazard of some in operation.
In sum, the lower support meanss of existing hydraulic climbing die block system increasingly can not meet modern architecture construction
Low-risk, high efficiency, the requirement of low cost, in order to improve the work efficiency of hydraulic climbing die block system, reduce security risk, operate into
Labor intensity of this and workpeople, therefore researches and develops a kind of can climbing and the hydraulic climbing die block system of continuously adjustable with support body
Support meanss have become as those skilled in the art's technical barrier in the urgent need to address.
Utility model content
The purpose of this utility model is to provide a kind of turbine screw continuously adjustable for hydraulic climbing die block system
Support meanss, to solve to need when existing hydraulic climbing die block system climbs every time to repeat to arrange interim auxiliary jack and again adjust
Whole lower support meanss, thus the problems such as the inefficiency causing, cost up and potential safety hazard, by adjust supported on both sides it
Between distance, less barrier on travel path of can avoiding climbing；The construction of hydraulic climbing die block system is made more to meet modernization
The low-risk of construction, high efficiency, the requirement of low cost.

In other clamp left support seat 31 and right support seat 33, bearing pin 32 can be freely rotatable around the axis of itself；The centre of bearing pin 32 sets
Count into a two slightly in the middle of thin dumbbell structure, such design can either reduce material usage, can be again bearing pin 3 preferably
With rail contact, after wearing and tearing after a while, only need to cover an annulus set in the thick position in two and can be achieved with bearing pin 3 more
Change, greatly reduce maintenance cost；The outline of bearing pin 3 maximum must project above half I-shaped breach 16, makes and the connecing of track
Touch and be changed into being in rolling contact from sliding contact, greatly reduce the resistance when climbing for the track.
With reference to Fig. 1, Fig. 2 and Fig. 4, telescopic support legs 2 include turbine screw elevator 21,24, two wheels 23 of homalocephalus with
And axletree 22；Turbine screw elevator 21 is horizontally arranged on rear installing plate 13, and turbine screw elevator 21 includes handwheel
211st, worm shaft 212, housing 213, lifting screw 214 and turbine (not shown)；Handwheel 211 is arranged on worm shaft 212
Upper end, worm shaft 212 pass through housing 213 and be arranged on the turbine (not shown) cooperation of housing 213 the inside, turbine (figure
Not shown in) it is distribution and the intermeshing tooth of worm shaft 212 on an outline, and centre is a screwed hole, this screw thread
Hole and lifting screw 214 screw thread cooperatively form a screw thread pair；Therefore pass through to rotate handwheel 211, drive synchronous turn of worm shaft 212
Dynamic, it is further driven to be engaged with turbine (not shown) around own axis, final drive lifting screw is along itself
Axis moves linearly, thus realizing adjusting the purpose that lifting screw 214 pays distance；Axletree 22 is placed through homalocephalus 24 and pushes up
The pin-and-hole at end, and axletree 22 and pin-and-hole tight fit connection, can prevent from relative turning between axletree 22 and homalocephalus 24
Dynamic, improve sport efficiency and safety；Two wheels 23 are symmetrically arranged at the left and right sides of axletree 22, and wheel 23 is permissible
Freely rotatable around axletree 22 axis；Homalocephalus 24 is set in the top of lifting screw 214, and passes through two alignment pins and lifting
Screw rod 214 is fixedly connected, and this design both can ensure that the direction of wheel 23 rolling all the time straight up, reduces process of climbing
Resistance, can prevent homalocephalus 24 and lifting screw 214 from relatively rotating again, affect support effect.
In sum, this utility model provides the support of the turbine screw continuously adjustable for hydraulic climbing die block system to fill
Put 100, design is ingenious, and telescopic support legs 2 are provided with wheel 23 can be withstood on metope all the time, play truly overall process
In supporting role, it is to avoid climb support body when repeat to arrange interim auxiliary jack and to reset lower support meanss etc. numerous
Trivial operation, substantially increases work efficiency, decreases the quantity of operator, saves manpower and financial resources；Between adjusting
Spacing mechanism 4 can adjust the spacing between two telescopic support legs in left and right, less obstacle on travel path of can avoiding climbing
Thing, improves the adaptability of hydraulic climbing die block system；By worm and gear and screw thread pair Liang Tao mechanism, operator easily rotate
Handwheel 211 just can be realized adjusting the purpose of lifting screw 214, significantly reduce the labor intensity of operator, reduce
The probability that the security incidents such as falling from high altitude occur.
Foregoing description is only the description to this utility model preferred embodiment, not any limit to this utility model scope
Fixed, any change that the those of ordinary skill in this utility model field does according to the disclosure above content, modification, belonging to right will
Seek the protection domain of book.
