Abstract
The present invention is that the lifting device of sand core is installed and do not damaged to a kind of facilitate, including sand core, the sand core internal is set there are two arbor, the top of the arbor vertically extends the top of the sand core and two arbors are arranged symmetrically on the vertical axis of the sand core, the arbor top is equipped with screw hole, and suspension hook is equipped in the screw hole.For the arbor into inverted T-shaped structure, the horizontal bar portions of arbor inverted T-shaped structure are located at the inside of the sand core, and the top of the sand core is stretched out in the vertical bar part of arbor inverted T-shaped structure upwards.The present invention using in sand core the simple arbor of mounting structure realize lifting, can so ensure not have to the external outer damage for clamping, sand core will not being caused in sand core installation process；And can be dismantled between arbor and suspension hook, volume first can be so saved, is second avoided that the influence to suspender entirety when suspension hook damages.
Description
Technical field
The present invention relates to large-scale sand core mounting technique fields more particularly to a kind of facilitate to install and not damage the lifting of sand core
Instrument.
Background technology
, it is necessary to use big sand core in sand core casting, but the place of carrying can not be fixed outside sand core, commonly removed
Fortune may cause sand core to damage in the handling process.
Chinese patent (202606802 U of CN) provides " casting sand core suspender ", can easily be existed using this suspender
Outer clamping sand core, which is realized, to be carried, but sand core is finally in mold to be put into, and at this moment such clamping tooling can not just carry out just
Normal installation.For such case, someone has invented " a kind of heavy castings air cavity sand core rod " (106670395 A of CN) again,
But this arbor structure is more complicated, occupies when lifting that volume is larger, and suspension hook can not dismount, once suspension hook there is damage will
Arbor is caused to fail.
The content of the invention
Present invention seek to address that the deficiencies in the prior art, and a kind of facilitate is provided and installs and do not damage the slinger of sand core
Tool.
The present invention to achieve the above object, using following technical scheme：
A kind of to facilitate installation and do not damage the lifting device of sand core, including sand core, the sand core internal is set there are two arbor,
The top of the arbor vertically extends the top of the sand core and two arbors are arranged symmetrically on the vertical axis of the sand core,
The arbor top is equipped with screw hole, and suspension hook is equipped in the screw hole.
For the arbor into inverted T-shaped structure, the horizontal bar portions of arbor inverted T-shaped structure are located at the inside of the sand core, arbor
The top of the sand core is stretched out in the vertical bar part of inverted T-shaped structure upwards.
The vertical bar and horizon bar of the arbor are hollow round steel pipe, and the vertical bar and horizon bar are interconnected composition
The structure of one threeway, the vertical bar side wall are equipped with multiple gas vents, and the gas vent is located at the lower section of the screw hole
And expose the top of the sand core.
The beneficial effects of the invention are as follows：The present invention using in sand core the simple arbor of mounting structure come realize lift, this
Sample can ensure not having to the external outer damage for clamping, will not causing sand core in sand core installation process；And arbor and suspension hook it
Between can dismantle, first can so save volume, second be avoided that the influence to suspender entirety when suspension hook damages.The present invention
Sand core can also be vented in time, avoid phenomenon of choking with resentment.
Description of the drawings
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the schematic diagram of arbor；
Fig. 3 is the schematic diagram of suspension hook；
In figure：1- sand cores；2- arbors；3- suspension hooks；
It is described in detail referring to the drawings below with reference to the embodiment of the present invention.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples：
As shown in Figure 1 to Figure 3, it is a kind of to facilitate installation and do not damage the lifting device of sand core, including sand core 1, the sand core 1
It is internally provided with two arbors 2, the top of the arbor 2 vertically extends the top of the sand core 1 and two arbors 2 are on the sand
The vertical axis of core 1 is arranged symmetrically, and 2 top of arbor is equipped with screw hole, and suspension hook 3 is equipped in the screw hole.
For the arbor 2 into inverted T-shaped structure, the horizontal bar portions of 2 inverted T-shaped structure of arbor are located at the inside of the sand core 1, core
The top of the sand core 1 is stretched out in the vertical bar part of 2 inverted T-shaped structure of bone upwards.
The vertical bar and horizon bar of the arbor 2 are hollow round steel pipe, and the vertical bar and horizon bar are interconnected group
Into the structure of a threeway, the vertical bar side wall is equipped with multiple gas vents, and the gas vent is located under the screw hole
Side and the top for exposing the sand core 1.
The present invention using in sand core 1 the simple arbor 2 of mounting structure come realize lift, can so ensure that sand core 1 is pacified
Do not have to external clamping during dress, the outer damage of sand core 1 will not be caused；And can be dismantled between arbor 2 and suspension hook 3, this
First sample can save volume, be second avoided that the influence to suspender entirety when suspension hook 3 damages.During arbor 2 of the present invention uses
Empty round steel pipe and vertical bar side wall are equipped with multiple gas vents, and such design can also be vented sand core 1 in time, avoid choking with resentment existing
As.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the present invention implements and from aforesaid way
Limitation, as long as employ the inventive concept and technical scheme of the present invention progress various improvement or not improved direct application
In other occasions, within protection scope of the present invention.
