Abstract
The utility model provides a kind of foundation bolt extension mechanism.Internal screw thread is equipped in connector in the extension mechanism, the top of connector is provided with connector spanner position, and the outer circle portion for extending screw rod is equipped with external screw thread, extends at the top of screw rod and is provided with screw rod spanner position, extends screw rod and connector is attached by screw thread.The extension mechanism is divided into connector and extends screw rod, the connector of this structure and extend screw rod and can flexibly be adapted to various length screw rods with separate machined, can after equipment is in place installation connecting element again, extension screw rod is then installed again, extension screw rod is then tightened by spanner position.
Description
Technical field
The utility model relates to arrive machinery field, it is related specifically to a kind of foundation bolt extension mechanism.
Background technique
Foundation bolt is common connector in chemical industry equipment installation process, and effect is that equipment is fixed to concrete pedestal
On, structure possesses stronger fastness and stability.
During embedding anchor bolts, due to level measurement mistake and device structure change etc., often occur pre-
The foundation bolt exposed portion buried phenomenon on the low side, can only will it is entire basis remove after pour again, not only wasted material in this way but also
Waste of manpower and time, quality not can guarantee yet, and directly affect the overall progress of engineering.
Patent No. 201620625375.1, patent name are a kind of lengthening spiral shell for the installation of steel building lower margin
Bolt, technical characteristic is tightening portion upper end and lengthening end is an entirety, and there are following shortcomings for this structure: 1, this
Structure needs turning drilling blind hole, and it is big to process inconvenient difficulty for the outer silk of a vehicle of first tap internal thread one；2, this structure need to be by tightening portion diameter
It stocks up, turnery processing amount is more, waste of raw materials is also more；3, need integral replacing waste larger when replacing；4, most importantly because
Equipment installation diameter of bolt hole is more slightly bigger than foundation bolt diameter, can not pass through tightening portion when equipment is in place.
Summary of the invention
The purpose of this utility model is to provide one kind in order to reduce cost, easy to process, the simple lower margin of repair and replacement
Bolt extends mechanism.
To achieve the above object, the technical solution of the utility model are as follows:
A kind of foundation bolt extends mechanism, including connector and extends screw rod, sets in the connector extended in mechanism
There is internal screw thread, the top of connector is provided with connector spanner position, and the outer circle portion for extending screw rod is equipped with external screw thread, extends the top of screw rod
Portion is provided with screw rod spanner position, extends screw rod and connector is attached by screw thread.
Compared with prior art, the good effect of the utility model are as follows:
1, the extension mechanism is divided into connector and extends screw rod, and the connector and extension screw rod of this structure, which can separate, to be added
Work can flexibly be adapted to various length screw rods；
2, the connector in the extension mechanism is easy to process, only holes drilled through is needed to attack harness cord；
3, the extension mechanism saves material, and turning part is less；
4, the extension mechanism can after equipment is in place installation connecting element again, extension screw rod is then installed again, is then passed through
Tighten extension screw rod in spanner position.
Detailed description of the invention
Fig. 1, foundation bolt extend the schematic cross-sectional view of mechanism.
In figure；1, foundation bolt, 2, connector, 3, connector spanner position, 4, extension screw rod, 5, extension screw rod spanner position,
6, upper ring plate, 7, lower ring plate, 8, concrete pedestal face.
Specific embodiment
Clear, complete description further is carried out to the technical solution of the utility model with reference to the accompanying drawing.
Referring to attached drawing 1, in equipment installation, the lower ring plate 7 of equipment is mounted on concrete pedestal face 8, and the upper ring of equipment
Plate 6 should be connected with foundation bolt 1.When 1 length of foundation bolt is inadequate, by the internal screw thread in connector 2 by connector 2 with
Foundation bolt 1 is connected, and is fastened by the connector spanner position 3 at 2 top of connector, then will extend screw rod 4 and passes through
Mounting hole on equipment upper ring plate 6, the external screw thread by extending screw rod 4 are connected with the internal screw thread of connector 2, will extend screw rod
4 are connected on connector 2, and the extension screw rod spanner position 5 by extending 4 top of screw rod is fastened.Screw rod 4 will finally be extended
Fixation is attached by nut and the upper ring plate of equipment 6.Extend the diameter of screw rod 4 and the internal diameter of connector 2, it can be according to installation
Aperture on the upper ring plate 6 of equipment is changed.
