Description
Technical field
The utility model relates to a kind of large-scale dam steel gate back rod tension stress proving installation, belongs to mechanical test device field.
Background technology
According to " ship lock gate and valve design specifications " (JTJ308-2003), to choke water caused huge moment of torsion and unfavorable operating modes such as gate flap self center of gravity and shearing force off(-)center when gate flap opens and closes in front of the door in order overcoming, need to handle by miter gate's back rod being carried out prestressed stretch-draw, with the one-piece construction torsional property of increase miter gate body.
Generally, steel gate back rod prestress method of testing is defined as the foil gauge electrical measuring method.But at the construction field (site); because gate back rod stretch-draw debugging work is consuming time than growing even need carrying out stress continuous monitoring in many days; therebetween; owing to reasons such as shutting down outage, power down and welder power impact all makes the required ideal source condition of Strain Method test job be difficult to satisfy, thereby can't adopt the electrical measurement Strain Method that the back rod stretch-draw prestressing force is carried out continuous monitoring between steel gate limber up period.
Summary of the invention
The purpose of this utility model provides a kind of large-scale dam steel gate back rod tension stress proving installation simple in structure, it need not use power supply, namely can in the prestressed long-time debugging of steel gate back rod installation period (even in tens days), carry out prestressed continuous monitoring, to overcome existing proving installation can't carry out continuous monitoring to the back rod stretch-draw prestressing force under the power failure situation problem.
The utility model is realized by following technical scheme: a kind of large-scale dam steel gate back rod tension stress proving installation comprises rigidity measuring staff 1, dial gauge 2, dial gauge holder 3, pedestal 5, dial gauge table bar 7, back rod 8; Rigidity measuring staff 1, pedestal 5 are installed on the back rod 7, dial gauge holder 3 is installed on the pedestal 5 by the fastening bolt 4 which is provided with, dial gauge 2 is installed on the dial gauge table bar 7, dial gauge table bar 7 one ends are installed on the dial gauge holder 3, and the set rigidity measuring staff in the other end and rigidity measuring staff 1 end is measured 6 pairs of tops of end face.
Described dial gauge 2 can be clock gauge, and its measuring accuracy can improve a number level.
The utlity model has following beneficial effect:
1, measuring principle is clear, operation is simple, visual result, measurement mechanism are with low cost;
2, big, the reliable measuring data of stress instrumentation datum length, precision height;
3, not influenced by power supply source and construction environment, be convenient to the field work rig-site utilization.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Each label is among the figure: 1: rigidity measuring staff, 2: dial gauge, 3: dial gauge holder, 4: fastening bolt, 5: pedestal, 6: the rigidity measuring staff is measured end face, 7: dial gauge table bar, 8: back rod.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail, but content of the present utility model is not limited to described scope.
Embodiment 1: as shown in Figure 1, a kind of large-scale dam steel gate back rod tension stress proving installation comprises rigidity measuring staff 1, dial gauge 2, dial gauge holder 3, pedestal 5, dial gauge table bar 7, back rod 8; Rigidity measuring staff 1, pedestal 5 are installed on the back rod 7, dial gauge holder 3 is installed on the pedestal 5 by the fastening bolt 4 which is provided with, dial gauge 2 is installed on the dial gauge table bar 7, dial gauge table bar 7 one ends are installed on the dial gauge holder 3, and the set rigidity measuring staff in the other end and rigidity measuring staff 1 end is measured 6 pairs of tops of end face.Dial gauge 2 can be clock gauge, and its measuring accuracy can improve a number level.
