Description

A kind of rotary seat for drillng operation

Technical field

The utility model relates to driller's chair art, especially a kind of rotary seat for drillng operation.

Background technique

Drilling platforms face is all steel plate structure, and greasy dirt is more above platform, is easy to happen using existing rotary seat Seat is toppled over, and the safety of Field Force is endangered, this, which just needs seat can satisfy, can rotate and be capable of fixing in flat surface, and It is limited by space space, therefore driller's chair support shaft is designed at the edge (accentric support) of seat, driller is facilitated to pass in and out.

Utility model content

The shortcomings that the purpose of the utility model is to overcome the prior arts, it is simple to provide a kind of structure, design rationally, rationally Utilize the drillng operation rotary seat in space.

The purpose of this utility model is achieved through the following technical solutions: a kind of rotary seat for drillng operation, packet Bracket rotating mechanism and seat support rack are included, the bracket rotating mechanism includes bearing, seat fixing seat, the bearing peace In pedestal, the seat support rack includes seat mounting plate and shaft, and the seat mounting plate is mounted on shaft Upper end, shaft are mounted in the inner ring of bearing, and the seat fixed seating is located in shaft.

Specifically, stiffener plate is provided between the bottom and shaft of the seat mounting plate.

Specifically, it is also arranged with trim in the shaft, trim wraps seat fixing seat.

Specifically, the bearing is four point touching ball slewing bearing.

Specifically, the seat mounting plate is rectangle, and shaft and seat mounting plate junction are located at seat mounting plate One of angle.

Specifically, the seat fixing seat is circumferentially evenly arranged with multiple mounting holes.

Specifically, the seat mounting plate is engraved structure.

The utility model has the advantage that the utility model has the advantages of simple structure, can use in particular surroundings operation, (2) dual rotary concept is introduced, ergonomics is incorporated, humanization designing not only can satisfy production needs, but also be able to satisfy operator Member is seated comfortably, and seat support rack is eccentrically rotated the case where can be used for plane convex-concave, and driller's chair support shaft is designed in seat Edge, facilitate driller to pass in and out.

Specific embodiment

The utility model is further described with reference to the accompanying drawing, but the protection scope of the utility model is not limited to It is as described below.

As shown in Fig. 1 ~ 4, a kind of rotary seat for drillng operation, including bracket rotating mechanism and seat support rack, The bracket rotating mechanism includes bearing 3, seat fixing seat 4, and the bearing 3 is mounted in pedestal 6, the seat branch Support includes seat mounting plate 2 and shaft 1, and the seat mounting plate 2 is mounted on the upper end of shaft 1, and shaft 1 is mounted on bearing In 3 inner ring, the seat fixing seat 4 is set in shaft 1.

Further, stiffener plate 7 is provided between the bottom and shaft 1 of the seat mounting plate 2.

Further, it is also arranged with trim 5 in the shaft 1, trim 5 wraps seat fixing seat 4.

Further, the bearing 3 is four point touching ball slewing bearing, controls seat using four point touching ball slewing bearing Chair is eccentrically rotated.

Further, the seat mounting plate 2 is rectangle, and shaft 1 and 2 junction of seat mounting plate are located at seat installation Single-point support is realized at one of angle of plate 2.

Further, the seat fixing seat 4 is circumferential is evenly arranged with multiple mounting holes 8.

Further, the seat mounting plate 2 is engraved structure, can be filled not on seat mounting plate 2 when in use The seat of same type meets different Man's Demands.

The above, the only preferred embodiment of the utility model, not do limit in any form to the utility model System.Anyone skilled in the art, in the case where not departing from technical solutions of the utility model ambit, all using above-mentioned The technology contents make many possible changes and modifications to technical solutions of the utility model, or be revised as equivalent variations etc. Imitate embodiment.Therefore, all contents without departing from technical solutions of the utility model, the technology according to the utility model is to the above reality Any change modification, equivalent variations and modification that example is made are applied, the protection scope of the technical program is belonged to.
