Abstract
The utility model relates to an installing and fixing device of large-scale equipment, in particular to a fastening device of a foundation bolt. The precise fastening device of the foundation bolt is arranged on the foundation bolt. The precise fastening device comprises a base plate, a fore bearing nut, two hydraulic jacks and a set of dialgauges, wherein a welding piece of a reinforcing rib plate is used as the base plate, the fore bearing nut is screwed into the foundation bolt and then is welded with the base plate, the two hydraulic jacks are supported under the two sides of the base plate, and the set of dialgauges is arranged on the upper surface of the base plate. The problem that a special fastening device is insufficient or an operation space is limited when the foundation bolt is fastened in an electromechanical equipment installing engineering is solved, and the foundation bolt can be precisely fastened.
Description
Technical field
The utility model relates to the fixing device for installing of main equipment, relates in particular to a kind of fastener of foundation bolt.
Background technology
In the equipment installation process, especially main equipment is installed, foundation bolt is bigger, fastening force is also bigger, and fastening force requires comparatively accurate, typically use the hydraulic nut stretcher that specialized factory produces, differently foot bolt will use different devices, cost is higher, and a crucial problem often puzzlement in work progress, be exactly that hydraulic nut stretcher volume is bigger, run into the foundation bolt installing space and can't use when special, the workmen can only be by virtue of experience foot bolt securely, be difficult to accurately reach required value.
Summary of the invention
The utility model is intended to address the above problem, and provides a kind of foundation bolt accurate fastener.The utility model has solved when foundation bolt is fastening in the electromechanical equipment installing engineering special-purpose fastened tools deficiency or the limited problem in operating space, and can be accurately foot bolt securely.
The utility model is achieved in that
The accurate fastener of a kind of foundation bolt, it is installed on the foundation bolt, and it comprises:
A base plate, it is a reinforcing gusset weldment;
Stressed nut welds with base plate behind the precession foundation bolt,
Two hydraulic jack, they shore the down either side at base plate;
One cover dial gauge group is arranged on plate upper surface.
The utility model uses the hydraulic cylinder application of force, makes foundation bolt produce stretcher strain, and dial gauge is measured the method for foundation bolt deflection, has solved special-purpose fastened tools deficiency or the limited problem in operating space when foundation bolt is fastening in the electromechanical equipment installing engineering.The utility model detects the detection that is converted to the elastic deformation amount with foundation bolt fastening force (square), and the stretcher strain amount detects can be accurate to 0.01mm, reaches accurately the purpose of foot bolt securely.
The utility model is simple in structure, is easy to make; Operate portable, practical; Manufacturing process is simple, uses portable, accurate, widely applicable.Compare with hydraulic nut stretcher, hydraulic spanner, cheap, economical and practical.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1: the accurate fastener of a kind of foundation bolt, it is installed in (6 are anchor nut among the figure) on the foundation bolt 5, and it comprises:
A base plate 1, it is a reinforcing gusset weldment;
Stressed nut 2 welds with base plate 1 behind the precession foundation bolt,
Two hydraulic jack 4, they shore the down either side at base plate 1;
One cover dial gauge group 3 is arranged on base plate 1 upper surface.
