Abstract
The utility model discloses a vertical pit furnace cover, and belongs to the technical field of heating electric furnace equipment for the heat treatment of metals. The vertical pit furnace cover comprises a furnace body and a furnace cover, wherein the furnace cover is covered on the furnace body. The vertical pit furnace cover is characterized in that the furnace cover is composed of two semicircular covers, one end of the furnace cover is connected to a bearing pedestal through an ear piece, the bearing pedestal is connected with an elevator, the ear piece is connected with a pneumatic cylinder, a support bar is welded on the ear piece, a handle is vertically arranged on the support bar, and the handle is fixed on the furnace cover. The vertical pit furnace cover disclosed by the utility model is simple in structure and reasonable in design; the furnace cover can be opened just through slowly lifting up the furnace cover through the elevator and then stretching the furnace cover to the two sides thereof by using the pneumatic cylinder; and the vertical pit furnace cover is easy to use, simple in manufacturing and low in cost.
Description
Technical field
The utility model relates to metal heat treatmet heating furnace equipment technical field, is specifically related to a kind of pit furnace lid.
Background technology
At present, well formula resistance furnace furnace diameter generally adopts one-piece construction at the large-scale bell more than a meter, the well formula resistance furnace bell that the former Soviet Union supports China adopts one-piece construction, circular public attention curved plate thickness is eight to ten millimeters not to be waited, build in circular public attention and paste the arch high alumina brick, who knows to amplexiform to polish that thermopair socket and view port and hoisting ring etc. are stayed in top by aluminum oxide.The monoblock type bell in use produces thermal distortion easily, and crane lifting is very large to the impact of bell and body of heater simultaneously, and unfavorable to the sealing location of bell.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of reasonable in design, makes simple, easy to operate pit furnace lid.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of pit furnace lid, comprise body of heater and bell, bell covers on body of heater, it is characterized in that: described bell is the semicircle lids of two fans, and described bell one end is connected on the bearing support by ear piece, and bearing support is connected with elevator, be connected with pneumatic cylinder on the described ear piece, also be welded with support bar on the described ear piece, vertically be provided with handle on the support bar, described handle is fixed on the bell.
Described ear piece is Λ type structure.
Described pneumatic cylinder is connected on the ear piece by pull bar.
Described pneumatic cylinder is provided with two.
The beneficial effects of the utility model are: the utility model is simple in structure, reasonable in design, by elevator bell is slowly raise, and then utilizes pneumatic cylinder to two side stretchings, bell can be opened, easy to use, make simple, cost is lower.
Description of drawings
Fig. 1 is a kind of pit furnace lid of the utility model structural representation.
Wherein: the 1-body of heater; The 2-bell; The 3-ear piece; The 4-bearing support; The 5-elevator; The 6-pneumatic cylinder; The 7-support bar; The 8-handle; The 9-pull bar.
Embodiment
For technique means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of pit furnace lid, comprise body of heater 1 and bell 2, bell 2 covers on body of heater 1, bell 2 is the semicircle lids of two fans, bell 2 one ends are connected on the bearing support 4 by ear piece 3, ear piece 3 is Λ type structure, and bearing support 4 is connected with elevator 5, is connected with pneumatic cylinder 6 on the ear piece 3, pneumatic cylinder 6 is connected on the ear piece 3 by pull bar 9, pneumatic cylinder 6 has two, is arranged on the ear piece 3 of bell 2 both sides, also is welded with support bar 7 on the ear piece 3, vertically be provided with handle 8 on the support bar 7, handle 8 is fixed on the bell 2.
The utility model is to realize like this, elevator 5 drives ear piece 3 and upwards promotes, thereby driving bell 2 upwards mentions, the pneumatic cylinder 6 of the process middle distance both sides that bell 2 upwards shifts to an earlier date is more and more far away, after bell 2 rises to a certain degree, pneumatic cylinder 6 work of both sides are to post shrinkage, and two fans are semicircle to be covered thereby pull open, and bell 2 namely is opened.
More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification sheets just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
