Abstract
The dynamically weighing sensing device of the cement pneumatic mortar machine of dynamic weighing use is provided while providing in a kind of bridge construction mechanical field its churn material loading of pneumatic mortar machine the utility model.This device is, at the top of described LOAD CELLS one end, the described pressure bearing head being threaded is set.Owing to having taked the combination of LOAD CELLS and pressure bearing head, can make full use of pressure bearing head follows the feature of rotation and effectively eliminates churn and vibrate the impact bringing to LOAD CELLS, and the power of vertical direction is passed to LOAD CELLS, not only make pneumatic mortar machine dynamic weighing come true, made up the defect that prior art exists, reliably realized goal of the invention, and weighing data is more accurate.In weighting error is controlled at≤0.5% scope.The advantage such as that this device also has is simple and compact for structure, convenient for installation and maintenance, stable and reliable for performance, be suitable for promoting.
Description
Technical field
The utility model relates to the sensing device of dynamic weighing, carries out the sensing device of the dynamic weighing of dynamic weighing use while exactly relating in bridge construction mechanical field its churn material loading of pneumatic mortar machine.
Technical background
At present, the high-speed railway develop rapidly of China, well known high-speed railway all be unable to do without bridge.High-speed Railway Bridges is to be formed by connecting by carrier bar.In order to increase the physical strength of carrier bar, in the erection process of High-speed Railway Bridges, in round set on carrier bar, penetrate prestress wire, then in penetrating the round of prestress wire, casting cement is starched again.Its grout is generally by cement, grouting agent and water, according to certain weight proportion, to be sent in the churn of pneumatic mortar machine or bottle placer to be uniformly mixed.Then pour into a mould.Because High-speed Railway Bridges is quite strict to carrier bar technical requirement, and the precision that material takes directly has influence on grout, carrier bar and even High-speed Railway Bridges construction quality, safe coefficient and serviceable life.The material loading Weighing mechanism in the past using is LOAD CELLS to be set and signal is passed to controller at the bracing frame middle part of churn bottom.Described LOAD CELLS all adopts static sensor, during work because the reasons such as churn vibration can cause weighing inaccurate.So, just cannot guarantee construction quality and the serviceable life of grout, carrier bar and even High-speed Railway Bridges, also can bring great potential safety hazard to High-speed Railway Bridges.
Summary of the invention
The purpose of this utility model is to provide a kind of dynamically weighing sensing device of cement pneumatic mortar machine, mainly to solve existing cement pneumatic mortar machine LOAD CELLS to adopt static sensor to weigh inaccurate, cannot guarantee construction quality and the serviceable life of grout in work progress, carrier bar and even High-speed Railway Bridges, and have the problem of potential safety hazard.
The technical solution of the utility model is as described below: it comprises LOAD CELLS and pressure bearing head, and the described pressure bearing head being threaded by the top setting in described LOAD CELLS one end is realized.
The beneficial effects of the utility model: this utility model is owing to having taked the combination of LOAD CELLS and pressure bearing head, can make full use of pressure bearing head follows the feature of rotation and effectively eliminates churn and vibrate the impact bringing to LOAD CELLS, and the power of vertical direction is passed to LOAD CELLS, not only make pneumatic mortar machine dynamic weighing come true, made up the defect that prior art exists, reliably realized goal of the invention, and weighing data is more accurate.In weighting error is controlled at≤0.5% scope.The advantage such as that this device also has is simple and compact for structure, convenient for installation and maintenance, stable and reliable for performance, be suitable for promoting.

Embodiment
Dynamically weighing sensing device by the cement pneumatic mortar machine shown in Fig. 1-Fig. 4 is a kind of novel dynamically weighing sensing device designing on prior art basis.It is comprised of LOAD CELLS 1 and pressure bearing head 2 two parts.LOAD CELLS 1 and pressure bearing head 2 are prior art.Be mainly by setting up vertical tapped through hole in LOAD CELLS 1 one end, and the screw thread pole through pressure bearing head 2 is connected and fixed pressure bearing head 2 and LOAD CELLS 1 at top.Because pressure bearing head 2 itself has the rotation of following, when churn produces vibration, it abuts in churn basal surface all the time, forms the support to churn, thereby effectively eliminates the negative effect that vibration brings dynamic weighing.
During work, each churn is used three dynamically weighing sensing devices, and is 120 ° of deciles.Dynamic weighing sensor integral body is through being bolted in churn lateral frame, and pressure bearing head 2 takes with churn the mode of joining of floating.Three dynamically weighing sensing devices are sent into output signal respectively complete machine controller and are controlled with processing and draw accurate weighing data.
Claims (2)
