Abstract
The utility model discloses a mud jacking flow metering device, including pressure sensor, mudjack, response bolt, pulse sensor, support, cable conductor, controller, wherein respond to the bolt and install on the input shaft of mudjack, pulse sensor installs on the support, and response bolt and pulse sensor cooperation are used, and pressure sensor connects on the delivery outlet of mudjack, and pulse sensor and pressure sensor all are connected through cable conductor and controller. Its beneficial effect does: mud jacking flow metering device, pulse quantity that the controller export through the measurement pulse sensor unit interval calculates the slurry volume that the mudjack unit interval exported to pressure according to the pressure sensor perception carries out the pressure correction to the volume, obtains comparatively accurate slurry volume, because the cement slurry need not through metering device, consequently can not produce any influence to metering device's measuring accuracy and life.
Description
Technical field
This utility model relates to construction implement field, particularly to a kind of mud jacking flow measurement device manufacturing post-stressed concrete beam.
Background technology
Mud jacking system is one of indispensable equipment in the construction of post-stressed concrete beam, is mainly used in the pipeline cement mortar press-in tension steel strand.In order to ensure squeezing quality, construction requires know cement mortar (a kind of by water, grouting agent and cement mixture slurry after high-speed stirred) amount (volume) in press-in pipeline number and the speed of press-in.Therefore, one of flow and flow velocity essential condition being to ensure that squeezing quality of accurately measuring cement mortar.
The device being traditionally used for fluid volume metering at present is mainly effusion meter, although the measuring principle of various effusion meter is not quite similar, but has a common ground, that is, metering device to be enabled flow across.It is known that cement is the hydraulicity inorganic coagulation material of a kind of powdery, adding water to stir into has after more strongly adherent cement mortar and can in atmosphere or harden in water, and with flow through place's adhesion, affect measuring accuracy and service life.Therefore, traditional effusion meter cannot be used for the flow measurement of cement mortar.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of mud jacking flow measurement device, to overcome the deficiency mentioned in above-mentioned background technology.
For achieving the above object, this utility model is achieved through the following technical solutions:
A kind of mud jacking flow measurement device, including pressure transducer, mudjack, sensing bolt, impulser, support, cable, controller, wherein sensing bolt is arranged on the power shaft of mudjack, impulser is rack-mount, sensing bolt and impulser with the use of, pressure transducer is connected on the delivery outlet of mudjack, and impulser and pressure transducer are all connected with controller by cable.
Preferably, described impulser is universal high-speed induction formula electrical switch, and under the effect of sensing bolt, exportable electric impulse signal is to controller.
Preferably, described pressure transducer is signal of telecommunication output transducer, can the size of output pressure of perception mudjack.
Preferably, described mudjack is general spiro rod formula mudjack, this continuous pulse free of mudjack pulp and will not bring air into, and mud jacking flow is directly proportional to rotating speed.
Mud jacking flow measurement device described in the utility model have the beneficial effect that described mud jacking flow measurement device, controller is by the number of pulses of metrical pulse sensor units time output, calculate the slurry volume of mudjack unit interval output, and according to the pressure of pressure sensor senses, volume is carried out pressure correction, it is thus achieved that accurately slurry volume；Owing to cement slurry needs not move through metering device, produce any impact thus without on the measuring accuracy of metering device and service life.

Detailed description of the invention
As it is shown in figure 1, be that this utility model mud jacking flow measurement device forms schematic diagram.
A kind of mud jacking flow measurement device, including pressure transducer 1, mudjack 2, sensing bolt 3, impulser 4, support 5, cable 6, controller 7, wherein sensing bolt 3 is arranged on the power shaft of mudjack 2, impulser 4 is arranged on support 5, sensing bolt 3 and impulser 4 with the use of, impulser 4 is by the velocity of rotation of the effect detection mudjack 2 of sensing bolt 3, pressure transducer 1 is connected on the delivery outlet of mudjack 2, and impulser 4 and pressure transducer 1 are all connected with controller 7 by cable 6.
Described impulser 4 is universal high-speed induction formula electrical switch, and under the effect of sensing bolt 3, exportable electric impulse signal is to controller 7.
Described pressure transducer 1 is signal of telecommunication output transducer, can the size of output pressure of perception mudjack 2.
Described mudjack 2 is general spiro rod formula mudjack, this continuous pulse free of mudjack pulp and will not bring air into, and mud jacking flow is directly proportional to rotating speed.
During work, impulser 4 is by the pulse duration frequency signal of action-reaction mudjack 2 velocity of rotation of sensing bolt 3, the number of pulses of controller 7 metrical pulse sensor 4 unit interval output, calculate the slurry volume of mudjack 2 unit interval output, and according to the pressure of pressure transducer 1 perception, volume is carried out pressure correction, thus obtain accurate slurry volume aggregate-value and unit time value (mud jacking speed), it is achieved the metering of mud jacking flow.
