Abstract
The utility model relates to a jack jacking support device, including the bottom plate, the bottom plate is the cuboid shape, is equipped with the semi -circular arc of an undercut on the bottom plate, and both sides are equipped with two gussets respectively between arc and the bottom plate, and the gusset cross -section is the right angled triangle form of hypotenuse indent, and the radian of the hypotenuse indent of gusset is identical with the radian of arc indent, the utility model discloses an adaptation stator lug appearance, adopt arcuate contact surface with the area of contact of increase with the atress position, the local reinforcement with the local strength of increase with the jack contact position is done to the below simultaneously, thereby can realize the conduction of power and can not damage equipment, the device is in the engineering of using the convex fulcrum of jack jacking, can make jack top and convex fulcrum dead contact, avoid because jack and the too little sliding phenomenon that appears of convex fulcrum contact surface, thereby the construction safety of using the jack operation has been guaranteed.
Description
Technical field
The utility model relates to weight-lifting equipment jack lifting technique field, particularly relates to a kind of jack jacking stand apparatus.
Background technology
In the hoisting process of thermal powerplant generator unit stator, because considering the load-carrying ability of hanging device, stator and end shield generally can be adopted to separate the construction technology lifted, need be padded and temporarily in place in base position in place when this just needs the lifting of stator, fall after rise also finally in place after installing end shield again, in falling process, general employing four force-applied positions of jack pushing tow stator (being generally hanger position), due to jack upper end and forced position area of contact less, cause forced position requirement too high, and have the possibility damaging forced position.
Summary of the invention
The utility model is intended to solve the deficiencies in the prior art, and a kind of jack jacking stand apparatus is provided, this device is in the engineering using jack jacking circular arc fulcrum, jack top can be made to contact completely with circular arc fulcrum, avoid due to jack and circular arc fulcrum contact surface is too little occurs sliding phenomenon, thus ensure that the construction safety using jack operation.
The utility model for achieving the above object, by the following technical solutions: a kind of jack jacking stand apparatus, it is characterized in that, comprise base plate, base plate is rectangular shape, and base plate is provided with one to the semicircle arc of lower recess, and between arc and base plate, both sides are respectively equipped with two gussets, gusset cross section is the right triangular shape of hypotenuse indent, and the radian of the hypotenuse indent of gusset and the radian of arc indent match.
The beneficial effects of the utility model are: the utility model is for adapting to stator hanger profile, adopt arc contact surface to increase the area of contact with forced position, local stiffening is done to increase the local strength with jack contact position in below simultaneously, thus can realizable force conduction and can not damage equipment, this device is in the engineering using jack jacking circular arc fulcrum, jack top can be made to contact completely with circular arc fulcrum, avoid due to jack and circular arc fulcrum contact surface is too little occurs sliding phenomenon, thus ensure that the construction safety using jack operation.

Fig. 4 is the utility model assembling left view;
In figure: 1-arc; 2-gusset; 3-base plate; 4-jack jacking bearing; 5-jack;
Be described in detail with reference to accompanying drawing below with reference to embodiment of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail:
A kind of jack jacking stand apparatus, comprise base plate 3, base plate 3 is rectangular shape, base plate 3 is provided with one to the semicircle arc 1 of lower recess, between arc 1 and base plate 3, both sides are respectively equipped with two gussets 2, gusset 2 cross section is the right triangular shape of hypotenuse indent, and the radian of the hypotenuse indent of gusset 2 and the radian of arc 1 indent match.
In use jack jacking bearing 4 is directly fixed on above jack 5, utilize its arc contact surface to increase the area of contact with forced position, simultaneously local stiffening is done to increase the local strength with jack 5 contact position in below, thus can realizable force conduction and can not damage equipment.Meet jack 5 overlying contact area little, higher condition is required to Bearing Seat Force, more stable, reliable.
By reference to the accompanying drawings the utility model is exemplarily described above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the various improvement that method of the present utility model is conceived and technical scheme is carried out; or directly apply to other occasion, all within protection domain of the present utility model without improving.
