Abstract
The utility model discloses an adjustable concrete pump pipe of flow belongs to building construction equipment field, and this adjustable concrete pump pipe of flow includes the tee bend pump line, is connected with main pump pipe and two branch pump lines on the tee bend pump line, is equipped with fluid pressure type flow control valve on the branch pump line, and fluid pressure type flow control valve fixes in the reaction frame, and reaction frame one end is fixed subaerial. The utility model is used for bridge concrete symmetry cantilever concreting construction. During concrete placement, fluid pressure type flow control valve opened totally on the pump line was divided to both sides, the synchronous transmission concrete, and accessible hydraulic pressure valve regulation divides pump line flow dimension, and some hun ning earth volumes are built to balanced both sides, guarantee synchronous symmetry and build. On the one hand, need not time -out concrete pumping and rely on the artifical dismouting pump line that relapses, use the hydraulic pressure valve simple effective, improve work efficiency, on the other hand effectively avoids promoting construction quality because of the discontinuous messenger's concrete of being under construction produces cold seam.
Description
Technical field
This utility model belongs to construction implement field, is specifically related to a kind of flow adjustable concrete pump line.
Background technology
At present, people, when utilizing delivery pump to carry out continuous rigid frame bridge superstructure cradle construction, typically all utilize unidirectional conduit repeatedly to dismantle and realize.Use unidirectional pump line speed of perfusion slow, easily make concrete produce cold seam because pouring discontinuous, affect construction quality；Dismount more frequent simultaneously, increase the abrasion of pump line, reduce the service life of pump line.It addition, use unidirectional pump line cannot ensure pouring speed and pouring consistent of cantilever two ends, cause both sides cloth unbalanced, easily cause cantilever two ends asymmetric.
And existing when carrying out two-way concreting by threeway pump line, mostly use and artificial tap the method that valve carries out opening and closing, when concreting opens and closes valve, having rubble is stuck in inside valve passage, and percussion is wasted time and energy, and easily plugging.
Utility model content
The purpose of this utility model is to provide a kind of flow adjustable concrete pump line.
Based on above-mentioned purpose, this utility model adopts the following technical scheme that a kind of flow adjustable concrete pump line, including threeway pump line, connect on threeway pump line and have main pump pipe and two wheel cylinder pipes, wheel cylinder pipe is provided with fluid pressure type flow control valve, fluid pressure type flow control valve is fixed in reaction frame, and reaction frame one end fixes on the ground.
Further, described fluid pressure type flow control valve includes valve plate, valve seat and hydraulic test, and valve seat is fixed on wheel cylinder pipe, and valve plate one end is fixed on hydraulic test, and valve plate free end passes valve seat, and valve plate is provided with the through hole consistent with caliber in wheel cylinder pipe；Hydraulic test includes oil pump and is fixed on hydraulic oil top on reaction frame, forms loop by petroleum pipeline and oil return pipe between hydraulic oil top and oil pump, and the top on hydraulic oil top is connected on valve plate.
Further, described through hole is located at the free end of valve plate.
Further, the length of described valve plate is more than 2 times of wheel cylinder pipe caliber.
Further, described main pump pipe is provided with clip.
Further, described threeway pump line is " people " font.
This utility model has the advantage that
(1) this utility model is constructed for concrete symmetry cantilever pouring, and in concreting process, both sides fluid pressure type flow control valve is opened simultaneously, synchronous transport concrete.Owing to bridge floor exists longitudinal gradient, there is the discrepancy in elevation in both sides discharging opening, limit, general low slope concrete flow quantity is big, when both sides weight concrete deviation is bigger than normal, weight concrete larger side fluid pressure type flow control valve turns down or cuts out, until opening fluid pressure type flow control valve when both sides weight concrete is consistent again, in real time both sides cantilever concreting rate is dynamically regulated, can ensure that cantilever symmetry pours, the cold seam produced because construction is discontinuous can be prevented effectively from, improve construction quality；
(2) this utility model achieves concrete bidirectional by threeway pump line and pours simultaneously, without relying on artificial repeated disassembled and assembled pump line, use hydraulic valve simply effective, improve work efficiency, solve pump line dismounting problem the most frequently, add the service life of pump line；
(3) it is externally provided with reaction frame at fluid pressure type flow control valve, the stability of fluid pressure type flow control valve and pump line can be strengthened；
(4) this utility model uses oil pump to be controlled regulating fluid pressure type flow control valve, and safety is time saving and energy saving, can also adjust concrete flow quantity, and after using flow adjustable concrete pump line, every 100 side's concreting activity durations averagely can save 1～2 hours.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is in the structural representation of the fluid pressure type flow control valve of closed mode.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in detail.
A kind of flow adjustable concrete pump line, its structure is as shown in Figure 1, including " people " font threeway pump line 2, connecting on threeway pump line 2 and have main pump pipe 1 and two wheel cylinder pipes 3, main pump pipe 1 is provided with clip 9, and wheel cylinder pipe 3 is provided with fluid pressure type flow control valve, its structure is as shown in Figure 2, fluid pressure type flow control valve is fixed in reaction frame 4, and reaction frame 4 one end is fixed on ground 13, can strengthen the stability of fluid pressure type flow control valve and pump line.
Described fluid pressure type flow control valve includes valve plate 7, valve seat 6 and hydraulic test, valve seat 6 is fixed on wheel cylinder pipe 3, valve plate 7 one end is fixed on hydraulic test, at valve plate 7 free end through valve seat 6, the end of valve plate 7 free end is provided with block 14, it is possible to prevent valve plate 7 all to skid off in valve seat 6, airtight between valve plate 7 and valve seat 6 it is slidably matched, the length of valve plate 7 is more than 2 times of the caliber of wheel cylinder pipe 3, the free end of valve plate 7 is provided with the through hole 8 consistent with the diameter of wheel cylinder pipe 3, when through hole 8 and wheel cylinder pipe 3 UNICOM, fluid pressure type flow control valve is in open mode, when through hole 8 staggers with wheel cylinder pipe 3, flow is gradually reduced, until through hole 8 staggers completely with wheel cylinder pipe 3, fluid pressure type flow control valve is closed.
