Description
Technical field
The utility model belongs to stripper apparatus, particularly relates to the demoulding jacking of pretensioning prestressed concrete track board assembly line
System.
Background technology
With the fast development of China Railway High-speed construction, the manufacture of track plates is produced after I, II, III types of CRTS- etc.
Diversified forms use III type pre-tensioning system track plates of plate-type ballastless track CRTS at present in industry.The track plates of any specification
It is both needed to by multiple working procedure in production, wherein including demolding of track slab process.Track plates production be based on mold, by
The dies cavity of preset steel reinforcement cage and presstressed reinforcing steel cast concrete forms track plates after shaping, conserving, after maintenance molding
Track plates the production process for completing track plates is removed from railway plate die by stripping process.It is demoulded in actual production at present
Process needs to complete the removal of track plates by tearing conjunction open or integrally hanging away die end, side form.There is such as above-mentioned releasing process
Lower defect:
1, existing releasing process is to timely use in concrete final set and when reaching strength of mould stripping and shake pressure type jack manually
It is positioned over 4 points of mold side form both sides and the modes such as corresponds to the pressure being balanced by manpower on holder, shake, prize and demould, not only take a lot of work
It is time-consuming, damage is also also easy to produce to mold;Simultaneously because easily there is pitted skin, falls in the asynchronous track plates shape that results in of manual operation
It is skin, arrisdefect, even cracked, seriously affect the Forming Quality of track plates.
2, existing releasing process usually requires, by the end side mould folding of mold or the whole pattern dismantled same plate and hung away, to lead
It causes to re-pack every time and is required to readjust molding.Due to joining to the shape, size, surface of track plates in track board production technology
The conditions requirements such as number, internal steel bar arrangement are very high, tear open mold the consistency it is difficult to ensure that mold installation accuracy every time.Tear conjunction open simultaneously
It is molded as the human and material resources of construction and temporal significant wastage, quality, construction because of installation accuracy requirement height to construction personnel
Place space and facility requirements it is higher.
3, existing complete demoulding equipment larger, the using trouble that there is volume mostly, many equipment needs are hung by the external world
It transports equipment and carries out transport realization repeatedly;To there is the degree of automation in some so-called small automatic demoulding equipments not high again, needs more
The problems such as people is dismantled repeatedly, contraposition, it is difficult to be used well in practice.
To make Chinese high ferro fast development go abroad, meet the Belt and Road and《Made in China 2025》Composite strategies are wanted
It asks, the keen competition for adapting to current international high speed railway construction needs, and it is succinct to research and develop more advanced, process intelligent, process
The III type pre-tensioned rail plate production lines of CRTS of science are imperative.Stripping process and auxiliary facility are as crucial work therein
Sequence and corollary equipment are not only one of the technological difficulties in design and production process, while being also the important research and development side of this field
To.
The company standard that Chinese Railway parent company prints and distributes《High-speed railway CRTSIII plate-type non-fragment orbit pre-tensioning systems are answered in advance
Power concrete railway board》(Q/CR567-2017) in 3.3.7 and《High-speed railway CRTSIII plate-type non-fragment orbit pre-tensioning systems are pre-
The provisional technology of prestressed concrete track plates requires (flowing water unit method)》(TK/GW156-2016) 3.3.6 carries stripping process in
Specific requirement is gone out:When demoulding, track plates answer slow depanning, and ensure track plates be not hit, each position uniform force.
There is requirement to construction technology, it is necessary to assure track plates are slow ejection, uniform force in knockout course and are not hit
State.

Histogram is lifted to jacking, with the mold separation.
It is set on railway plate die bed die (8) there are three the jacking region (4), described three jack region (4) same
External force straight up under the action of track plates can be jacked up vertically.
Three jacking regions standing on the longer center line in track plates upper surface, enable the jacking region possess compared with
Big forced area, and each jacking is interregional away from suitable, it being capable of producing balanced forces ... ....
There are following technological deficiencies for the above-mentioned prior art:
Since the technical solution completes lifting operation by the preset three grout hole cavitys of railway plate die, due to filling
Slurry hole is linearly distributed on mold, and jacking force position is wire type, and track plates dimensions and dead weight are larger, and one is difficult to completely
Track plates answer the technological requirement of uniform force, track plates to be easy to demould because of unbalance stress during demoulding in sufficient current standard
Process is unstable, the case where causing to generate card resistance with mold or can not demould when serious;Second is that grout hole cavity is logical when making sheet
It crosses screw to fix in railway plate die, jacking stripping operation is both needed to loosen grout hole cavity every time, and palpus will after the completion of demoulding
Grout hole cavity reinstalls fixed and dies cavity, and operating procedure is complicated and the degree of automation is low.
