Description
Technical field
It the utility model is related to the releasing process equipment in high-speed railway slag-free rail plate prefabrication process, specially a kind of spiral shell
Rod-type synchronization of jacking up automatically controls demolding of track slab machine.
Background technology
High-speed railway is the important infrastructure of country, the main artery of national economy and the popular vehicles, is comprehensive
The backbone of communications and transportation system is closed, is played an important role in the good and fast development of China's economic society is promoted.With at a high speed
The development of railway, plate-type ballastless track construction technology are increasingly becoming most important construction technology in domestic high speed railway construction, special
It is not the type track slab construction technologies of CRTS III of China's independent research, is positioned the key technology that Chinese high ferro is gone abroad.Such as
The construction quality of what guarantee track plates, quality when particularly controlling demolding of track slab are particularly critical.III type track plates are divided into
P5600, P4925, P4856 three types, its monolithic track plates weight is respectively 7.57t, 6.66t, 6.58t, using two-way elder generation
Tension prestress reinforced concrete structure, track plates longitudinal prestressing muscle kernel of section is arranged symmetrically, in transversely prestressed bars section
The heart arranges, pre-buried fastener sleeve pipe in track plates, the symmetrical pre-buried 4 groups of lifting sleeve pipes of track plates longitudinal side, every group of 2 sleeve pipes（Such as
Shown in Fig. 4）.During demolding of track slab, hanger is installed at 4 groups of lifting sleeve pipes, track plates and mould point are driven by lifting hanger
From, and it is hoisted to track plates storage area.Before demolding of track slab, there are very big restraining force, and pre-buried fastener set between mould
Attachment force between pipe and mould is larger, and track plates deadweight is larger, causes the jacking strength that track plates need when being separated with mould very
Greatly.
At present, domestic generally use manually presses the mode of four jack to be stripped track plates.Jack is 5t screw
Jack, it is configured with depression bar.During construction, first hanger is installed on lifting sleeve pipe, installation will fasten, be closely connected；Then by 4 thousand
Jin top is placed on the reaction frame on mould respectively, and screw end head centering is touched into hanger；Finally pressed by 4 workmens
Jack is risen according to unified rhythm pressure, makes screw top hanging ear on jack, drives track plates to rise, be gradually disengaged, treat with mould
After track plates are kept completely separate with mould, driving handling track plates to storage area.
By the way of artificial four jack demoulding track plates of pressure, it is difficult to accomplish that the rhythm of personnel, power are synchronous, easily
In jacking track plate, screw rod protrusion height is inconsistent, causes track board concrete chip off-falling, and track big face can be caused when serious
Crack, crumble at product chip off-falling or Heave Here.
Therefore, current track plate demoulding urgent need will solve following several technical problems：
