Abstract
The utility model relates to an improved intrinsically safe operation box for a tunneling machine for coal mines, in particular to a full-enclosed intrinsically safe operation box suitable for various tunneling machines and capable of preventing water from entering into the box body. The operation box is provided with a box body, a panel, a silicone rubber keystroke and a pressure plate, wherein the panel is mounted in the box body, a keystroke port is formed on the panel, the silicone rubber keystroke is mounted at the keystroke port formed on the panel, and the pressure plate is arranged on the silicone rubber keystroke. The silicone rubber keystroke can play the effect of sealing, as well as a role of a film keystroke, and an electrical switch button can be operated through pressing the silicone rubber keystroke; a sealing groove is formed on a front flange on the box body, the panel and the box body are in direct flanged joint, and a sealing strip is adopted between the two for sealing; the protection grade of the casing of the operation box is IP54, only splashing water can be prevented, when the casing encounters with sprayed water or is immersed into water, water can infiltrate into the box body, causing failures. Therefore, the utility model solves the problem of infiltration of traditional intrinsically safe operation box.
Description
Technical field
The utility model relates to the improvement technology of coal mine tunnelling machine with the essential safe type control box, is specially a kind of hermetically sealed essential safe type control box, is applicable to various types of development machines.
Background technology
Because in some mines, top board had drowning phenomenon when development machine was dug the tunnel in the down-hole, the miner is when the cleaning operation case, adopt the direct flushing operation case of tap, and the shell protection grade that requires control box of coal peace authentication is for being not less than IP54, though the degree of protection of traditional control box reaches IP54, the shell protection grade can only prevent to dabble during for IP54, but at above situation, when shell runs into water spray, immersion, water just can penetrate in the casing, often causes infiltration in the control box, breaks down.Therefore, the essential safe type control box of developing a kind of all-sealed structure can solve above problem, can prevent effectively that sealing infiltrates in the casing.
The utility model content
The purpose of this utility model is to provide a kind of hermetically sealed essential safe type control box, solves the problem of infiltration in traditional essential safe type control box casing, cause the interior electric component of control box to break down, and then control box can't be worked.
The technical solution of the utility model is:
A kind of hermetically sealed essential safe type control box has casing, panel and button, and this control box is provided with casing, panel, silastic press key, pressing plate, panel is installed on the casing, have the button mouth on the panel, silastic press key is installed on button mouth place on the panel, and pressing plate is set on the silastic press key.
Described hermetically sealed essential safe type control box, the front end of casing is provided with forward flange, and the forward flange place has seal groove, and sealing strip is housed in the seal groove, adopts the sealing strip sealing between the forward flange of casing and the panel.
Described hermetically sealed essential safe type control box, panel directly is connected with the forward flange of casing.
Described hermetically sealed essential safe type control box, panel is connected by screw with the forward flange of casing.
The beneficial effects of the utility model are:
1, the hermetically sealed essential safe type control box of the utility model is equipped with silastic press key on panel, with pressing plate silicon rubber is compressed.Silastic press key promptly plays sealing function, plays the film key effect again, and panel directly is connected with the casing forward flange, adopts the sealing strip sealing in the middle of both.This mechanical structure has hermetically sealed property, can prevent that sealing infiltrates in the casing.
2, the utility model reliability, maintainability and safe.
3, the utility model designs in conjunction with the mine actual conditions, so the practicality height.

Fig. 1 is the utility model structural front view.
Fig. 2 is an A-A profile among Fig. 1.
Fig. 3 is the utility model structure vertical view.
Among the figure, 1, casing; 2, panel; 3, silastic press key; 4, pressing plate; 5, sealing strip; 6, screw; 7, forward flange.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1-Figure 3, the hermetically sealed essential safe type control box of the utility model mainly comprises: casing 1, panel 2, silastic press key 3, pressing plate 4, sealing strip 5, screw 6 etc., and concrete structure is as follows:
Have the button mouth on the panel 2, silastic press key 3 is installed on button mouth place on the panel 2, on the silastic press key 3 pressing plate is set.The front end of casing 1 is provided with forward flange 7, and forward flange 7 places of casing 1 have seal groove, and sealing strip 5 is housed in the seal groove, and panel 2 directly is connected by screw 6 with the forward flange 7 of casing 1.
During assembling,, silastic press key 3 is compressed with pressing plate 4 with the silastic press key 3 button mouth place on the panel 2 of packing into.Silastic press key 3 promptly plays sealing function, plays the film key effect again, can operate the electric switch button by pushing silastic press key 3.And have a seal groove at forward flange 7 places of casing 1, and sealing strip 5 is packed in the seal groove, and the forward flange 7 and the panel 2 of casing 1 adopts sealing strip 5 sealings between the two, and panel 2 is connected with casing 1 usefulness screw 6, is assembled into a hermetic control box at last.
