The utility model discloses segmentation detention concrete has slowed down the gliding speed of concrete, fine solution chute concrete glide in-process aggregate separation phenomenon and the drawback of concrete aggregate gradation change, ensured the working property in concrete warehousing and near chute discharge gate staff's life safety. The method is particularly suitable for the warehousing of the concrete chute with large aggregate fluidity and large chute inclination angle.
Description
Technical field
The utility model belongs to hydraulic engineering technical field, and in particular to a kind of concrete transporting chute.
Background technology
In current domestic project, whether concrete warehousing mode and transportation are to meeting concrete performance and concrete
Construction casting quality is particularly important.The mode of country's concrete warehousing mainly has dump truck, belt feeder, chute, cable machine at present
Etc. the mode of putting in storage.
By taking water resources dam construction as an example, because dam site bank slope is precipitous, riverbed bottom is narrow, and directly put in storage excavation using automobile
Road can not only destroy the integrality of dam abutment, and quantities is larger.Put in storage using belt feeder mode, aggregate open-assembly time mistake
Long, aggregate separated is particularly acute.And cable machine construction costs is high, cable-crane platform and treatment constructional difficulties are excavated.Due to environment construction
The limitation of condition, it is ensured that quality, it is considered to which the means of transportation of chute seems more quick, clever to concrete construction in the case of economy
It is living and cheap.Chute is simple structure, generally circular arc or rectangular notch, and manufacturing cost, maintenance cost are low, conveys intensity
It is high.
Sliding chute transportation disclosure satisfy that mass concrete continuous conveying, it is ensured that construction continuity.But still suffer from 3 problems：
1. concrete course of conveying speed in chute is fast and particles of aggregates is big, is mutually touched between aggregate during downslide
Hit, the friction between aggregate and inwall, cause aggregate to crush so that coagulation soil class allots raw change.
2. due to during downslide Binder Materials easily with chute interior walls occur part adhesive, particle and cunning during downslide
The continuous effect of groove causes that aggregate is separated, and influences the service behaviour and quality of concrete.
3., for the chute of long range, aggregate speed is more and more faster during concrete is glided due to Gravitative Loads, to slipping
Nearby staff produces unsafe factor to groove discharging opening.
The content of the invention
The technical problems to be solved in the utility model is：Change with performance for coagulation soil class present in chute downslide process
Become, aggregate separated and it is unfavorable to personal safety the problems such as, there is provided a kind of concrete transporting chute device with plate-turning door.
The technical solution of the utility model is as follows：
Flowed along concrete in a kind of concrete transporting chute with automatic turnover leaf door, including chute, the chute
Direction is provided with least one piece plate-turning door, and plate-turning door includes baffle plate, and baffle surface is coated with cushion, and baffle plate two ends are by support
Rotating shaft is connected with the madial wall of chute two, and support rotating shaft is connected on chute by fixing nut.
The cushion is elastomeric material.
The elastomeric material is rubber.
The baffle shapes are identical with chute inside cross-sectional shape.
The chute inside bottom is provided with wedge, and the wedge-shaped surface of wedge is tangent with baffle plate bottom.Wedge
For preventing automatic turning of the plate-turning door under effect of weight or under vibration effect, can be also used for adjusting initially inclining for plate-turning door
Rake angle.Wedge can be with mode connects for screw in chute bottom surface, and its quantity can be according to the deadweight of plate-turning door and width adjustment.
The baffle plate bottom is circular arc.
The utility model is mainly on the basis of traditional chute along the multiple new automatic turnover leaf doors of journey setting, the plate-turning door
It is made up of support rotating shaft, elastic cord breaker, baffle plate.Rotating shaft is fixed on chute by nut, for supporting baffle door and ensure oneself
Dynamic upset.Baffle plate mainly cuts stagnant concrete, it is ensured that coarse-fine aggregate and Binder Materials are not separated during downslide.Baffle surface sets
One layer of elastic cord breaker is put, on the one hand prevents that downslide aggregate speed is excessive will not to collide broken in baffle effect, led
Cause grading of aggregates to change, play a part of a protection in itself to baffle door in addition.
Operation principle of the present utility model is as follows：
Plate-turning door is closed first, and coagulation solifluction to plate-turning door front is stagnated, right as volume of concrete increases
Plate-turning door pressure resultant force application point is risen to more than rotating shaft, and plate-turning door is opened immediately.Concrete is slipped under starting, before plate-turning door
The reduction of square concrete, point of resultant force is reduced to below rotating shaft, and plate-turning door is automatically switched off, with concrete downslide sedimentation
Point rises to more than rotating shaft again, and plate-turning door repeats opening process again.The switching process serves a mix effect to concrete
Increased the fluidity of concrete.
According to inclination angle size, the effect and gliding speed that glide, position and number that the plate-turning door sets along journey are determined, it is mixed
Solidifying soil mobility is big, the big situation in chute inclination angle can number suitably increase.Can also disassembly, cleaning at any time slipped as general tradition
Groove is used.
Concrete is detained in the utility model segmentation, slow down the gliding speed of concrete, and chute coagulation is solved well
Soil glide during aggregate separated phenomenon and the drawbacks of aggregate gradation differentials, ensured the service behaviour of concrete warehousing
With the life safety of staff near chute discharging opening.It is particularly well-suited to the concrete that aggregate fluidity is big, chute inclination angle is big
Chute puts in storage.The utility model simple structure, it is easy for installation, high degree of automation is run, it is applicable ability by force, set flexible, peace
It is complete reliable.
