Abstract
The utility model discloses an overload prevention pouring system which can avoid overload in concrete pouring. The main structure of the overload prevention pouring system is a link mechanism which is composed of a supporting plate, a spring, a moving block and a lifting jack. The supporting plate with clamping grooves on two ends can drive the spring and the lifting jack with screws on two ends for protection. During the pouring process of concretes, when the concretes are poured increasingly full, the pressure is increased, and the born pressure of a blocking plate is increased, so that the link mechanism is driven to force the spring to contract and deform so as to open a notch, then the concretes fall down and the aim of pressure relieve is achieved. The overload pouring system is strong in adaptive capability, requires no special person for guarding, lowers labor intensity and saves large amounts of manpower and material resources.
Description
Technical field
The utility model relates to running gate system, is specially a kind of antioverloading running gate system that can be used for tunnel lining.
Background technology
At present, in the middle of the structure design of tunnel lining running gate system, mostly adopt the gate spool connecting line of a radicle bending, by the mode of dragging the direct pumping of concrete of pump to pour into a mould, the pressure release antioverloading system of design when not having specially at the cast overload.
Owing to there is not special antioverloading running gate system, in the middle of the process of cast, fluence and pouring pressure are watered in very difficult control, must have the special messenger to nurse the pump pressure table.And pressure changes with the variation of watering fluence, and excessive when cast, when pressure was excessive, chassis will produce distortion, when serious even collapse.So not only expend lot of manpower and material resources, when misoperation or unmanned guard, also may cause the chassis distortion, thereby serious accident takes place owing to pour into a mould the huge pressure of excessive generation.
The utility model content
The technical problem that the utility model solved is to provide a kind of antioverloading running gate system, and this antioverloading running gate system can be filled with die cavity at concrete, when producing excessive pressure, carries out self-relieving mode and solves shortcoming in the above-mentioned background technology.
The technical problem that the utility model solved realizes by the following technical solutions:
The antioverloading running gate system, its agent structure is a linkage of being made up of gripper shoe, spring, movable block, jack, wherein, gripper shoe is the channel plates of a two ends band draw-in groove, described spring is selected according to the maximum value of pouring pressure, and at one end be connected gripper shoe upper end, simultaneously, be provided with a nut structure at the spring other end and be used for the pretightning force of regulating spring.
Described gripper shoe lower end is connected two ends and is provided with on the end of jack of screw mandrel, and the jack other end is fixed on the movable block, the antioverloading baffle plate is set on the movable block, the antioverloading baffle plate is withstood by jack under normal condition, and is still in the sprue gate, can exert pressure by rotary screw rod or to spring, baffle plate is skidded off outside the sprue gate, form a breach, unnecessary concrete is gushed, to reach antioverloading purpose.
Under normal casting condition, system promotes the vacant locations that baffle plate makes it to block the sprue gate by spring pressure drivening rod mechanism, normal pumping of concrete; When concrete pouring was more and more expired, pressure increased, and baffle plate bears pressure and increases, and drivening rod mechanism forces the spring shrinkage strain to be made a breach, and this moment, concrete down dropped, and reached the purpose of pressure release.When closing pumping, when concrete was discharged to a certain degree, pressure diminished, and spring stress reduces, and extended drivening rod mechanism automatically, again breach was blocked up.Promptly finished an antioverloading casting process this moment.
Beneficial effect:The utility model can unload unnecessary pouring pressure automatically, nurses pressure meter and whole casting process without the special messenger, has reduced labour intensity, has saved lot of manpower and material resources, makes the construction of tunnel lining enter the construction degree of semi automatic machineization; It is improper to have stopped simultaneously because of manually-operated, causes pouring pressure to cross the danger that senior general's chassis is suppressed distortion even collapsed.And finish down in cast, movable block is concordant form surfacing external surface has also solved the problem of common sprue gate faulting of slab ends.
Description of drawings
Fig. 1 is the normal casting condition schematic diagram of the utility model.
Fig. 2 is the utility model cast antioverloading mouth opening schematic diagram.
Fig. 3 is the utility model sprue gate closed condition schematic diagram.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to the antioverloading running gate system of Fig. 1, Fig. 2, Fig. 3, under the state of Fig. 1, spring 2 compresses gripper shoe 1, and breach is closed, normal cast in the position of the length control movable block 4 by regulating screw mandrel jack 5.
When cast acquires a certain degree, when concrete pressure is excessive, force movable block 4 by jack 5 extruding gripper shoes 1, gripper shoe 1 forces spring 2 to shrink around the rotation of center hinge, opens movable block 4(such as Fig. 2 state), make concrete discharge, finish pumping of concrete this moment from breach.
When concrete is discharged to when a certain amount of, pressure reduces, and spring 2 stretches out, and drivening rod promotes screw mandrel jack 5, and system returns to the state of Fig. 1 again.Eject movable block 4 to panel top (as Fig. 3 state) by manually-operated screw mandrel jack 5 again, close sprue gate 3, this moment, a casting process finished.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the manual just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
