Description
Technical field
The utility model relates to a kind of concrete straddle-type monorail track straight beams to pour mould die opening mechanism, be a kind of structure letter
Single compact, die sinking quickly and efficiently, save resource, a kind of concrete track straight beam at low cost pours mould linkage die opening mechanism.
Background technique
In recent years, straddle-type monorail track Urban Transportation mode is being risen in China, and vehicle is to straddle concrete
It is run in monorail track beam, track girder serves not only as supporting beam, the also track as vehicle operation.To guarantee that vehicle is steady, pacifies
Row for the national games, to track girder pour precision and surface quality requirements are very high, pour molding and make precision, installation quality and demoulding process
Directly affect the quality and site operation progress of track girder.General 25~32 meters of long straight beams, pour mould effective length be 27~
It 34 meters, is mainly made of two sets of side forms and end mould, a set of fixed bed die and fixing tool.Each side form has four groups of die opening mechanisms:
Die opening mechanism is made of hydraulic jack, revolving die pull rod and support rod and trolley.Jack one end and trolley upper bracket are hinged, separately
One end and side form bottom trunnion are hinged；Revolving die pull rod and support rod one end can pedestal sliding on the car, the other end and side forms
Middle part is hinged；Support rod is scalable and is equipped with positioning pin；Speed reducer and sprocket drive system driving trolley on the car is set
It vertically moves and walks along side form；Operating platform is equipped at the top of every set side form.
Currently used side form die opening mechanism is: pouring mould to achieve the purpose that dismantle, hydraulic jack has been respectively adopted
Die sinking, the combination of manual rocker revolving die, machine driving shifting formwork.Before casting concrete, first fixed bed die, two side forms and end mould are determined
Position, straight beam width are fixed bed die width, length be two end intermodes away from.Check that each relative dimensions and precision conform to after positioning
It asks, then is fixed with tooling, by technique requirement casting concrete.Concrete dismantles again after reaching intensity requirement, removes and pours mould, opens
Mold process: fixing tool, end mould are first removed, then pulls open two side forms respectively and is turned out an angle, finally by trolley band
Dynamic to be movably walking along longitudinal rail, straight beam and fixed bed die stay put maintenance.
Die opening mechanism working principle: 1) using hydraulic jack side form and track girder is pulled open into certain distance；2) hand traverse
Side form is turned out after an angle by the transmission case handle on die drawing bar to be fixed with the positioning pin on support rod；3) start simultaneously
All speed reducers are driven driving trolley by sprocket wheel and walk with side form, realize completely separable with track girder, it is characterised in that: open
Mould hydraulic power, revolving die manual rocking handle, shifting formwork machine driven system, every group of trolley centralized arrangement hydraulic jack,
Manual rocking handle transmission case, machine driven system and side form support.
The disadvantage is that:
One, die opening mechanism is bulky: each side form is respectively provided with four groups of trolleys, is provided with hydraulic jack on every group of trolley
Top, revolving die pull rod, support rod, speed reducer and sprocket drive system, in addition longitudinal rail on side form both sides, whole occupied area
Greatly, it is more to occupy resource.
Two, affiliated facility is more: speed reducer and chain transmission system, hydraulic jack route, oil circuit above every group of trolley
All be fixed on side form and to meet the requirement being movably walking, not only increase side form weight and affiliated facility, be movably walking or
Execute-in-place trouble, and increase the unfavorable factors such as damage, electric leakage, oil leak.
Three, Resistance of opening mould is big: casting process side form bottom is rest directly upon on fixed bed die, and hydraulic jack is wanted when pulling open
Overcome the frictional force between side form and fixed bed die, between support rod and hand pull rod sliding bottom and trolley slideway, not only hinders
Power is big, it is also to be ensured that four groups of trolley slideway bases are parallel, in-site installation difficulty is big.
Four, there are security risks for rotation side form: side form is opened and is hung on the car after rotating an angle, can integrally be generated
Unbalanced moments, rotation process stability is very poor, to track girder, pours mould and operator brings some potential safety problems.
Five, the side form risk that is movably walking is big: side form it is total it is tall and big in 4 meters, be about 40 meters, weigh more than ten tons along with top is prominent
Walk on stage and affiliated facility etc., tiltedly hang over it is mobile on trolley run to few 40 meters or more of distance, it is extremely unstable, be movably walking
Journey generates great risk to facility and operator.
Six, straight beam casting process low efficiency: cast in situs straight beam quantity is more in engineering project, the direct shadow of job schedule
It rings the entire duration, the non-cutting times such as die sinking, rotation, walking are long.Restore again again when pouring next Pin beam, adjust, heavy workload,
Low efficiency.
Seven, it is more to occupy resource for die sinking process: cast in situs track girder, and the ground for pouring, conserving storage early period to Liang Chang is hard
The facilities such as change, laying I-steel rail, electricity, gas and water and oil circuit are arranged.Mobile side form rail is long, takes up a large area,
Electric power, the oil piping system of outfit are more, and engineering early investment is big, waste money, resource.
Eight, die opening mechanism is at high cost: the affiliated facility for being opened configuration is more, bulky, and the power of configuration is more and installation is wanted
Ask high, investment it is at high cost, die sinking power uses electric power, hydraulic power, machine driving etc..
