Abstract
The utility model relates to a switch transmission device, which comprises a travel switch and a three-dimensional rod, wherein the travel switch is installed on a machine inner shell opposite to an operating door and connected with a high voltage component inside a machine; and the three-dimensional rod is installed between the travel switch and the operating door of the machine in a certain mode. The length of the three-dimensional rod is greater than the distance between a contact and an operating port when the contact of the travel switch is at s reset state, the length difference ensures that the contact of the travel switch acts when the machine door is closed, a power supply is connected, and the machine operates normally. In order to further improve the safety, insulating strips can be additionally arranged at two ends of the three-dimensional rod respectively. The switch transmission device provided by the utility model provides a chance of secondary protection for the life of an operator, that is, even if the operator forgets to turn off the power supply because of negligence and the like, the power supply is turned off automatically as soon as the operating door of the machine is opened, so that the life of the operator is not harmed.
Description
Technical field
The utility model relates to a kind of switch gearing device.
Background technology
Along with the fast development of mechanical processing industry, the equipment of all kinds of use high-tension electricities spreads all over each corner of workshop, and this kind equipment all relates to the problem of a regular maintenance and maintenance.When operator need to carry out regular maintenance and when maintenance to machine, for safety must first disconnect power supply, but in operating process at ordinary times, operator can be because carelessness etc. be former thereby forgotten power-off sometimes, and this will work the mischief to operator's life.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of switch gearing device is provided, the effect of this switch gearing device is the moment that the actuating doors on machine is opened, switch gearing device motion makes machine auto-breaking, for operating personnel's life security provides further guarantee.
The technical solution adopted in the utility model is: a kind of switch gearing device, comprises travel switch and three-dimensional bar.Travel switch is arranged on the machine inner casing on actuating doors opposite, is connected with the high-tension electricity parts of machine intimate; This solid bar is arranged between travel switch and the actuating doors of machine by certain mode.Three-dimensional bar is insulating material, the length of three-dimensional bar is slightly larger than contact contact and the distance operating between doorway under reset mode of travel switch, and above-mentioned small length difference has guaranteed when machine door is closed, the contact action of travel switch, power supply is switched on, and machine is normally worked.
When the actuating doors of machine is in the state of closing, it is upper that one end of three-dimensional bar abuts against door, and the other end is pressed against on the contact of travel switch, contact action, and travel switch is switched on, the normal operation of machine energising; The moment being opened at machine operation door, three-dimensional bar has lost External Force Acting, and under the effect of travel switch contained spring, the contact of travel switch automatically resets, and travel switch disconnects, machine power-off.
In order further to improve fail safe, can increase insulating trip at the two ends of three-dimensional bar.
The beneficial effects of the utility model are: the life that switch gearing device described in the utility model is operator provides the chance of a second protection; even if operator has forgotten pass power supply because of reasons such as carelessness; open machine operation door moment machine also can auto-breaking, like this just can not work the mischief to operating personnel's life.
Accompanying drawing explanation
Below in conjunction with concrete drawings and Examples, the utility model is described further.
Fig. 1 is the profile of a specific embodiment of the present utility model when actuating doors is closed.
Fig. 2 is the profile of a specific embodiment of the present utility model when actuating doors is opened.
In figure:
1. 2. three-dimensional bar 5. travel switch 6. contacts of 3. insulating trip 4. of machine casing
Embodiment
As depicted in figs. 1 and 2, the switch gearing device described in a specific embodiment of the present utility model, comprises travel switch 5 and three-dimensional bar 4.Travel switch peace 5 is contained in the inside of machine, is connected with the high-tension electricity parts of machine intimate; Three-dimensional bar two ends are with insulating trip.This solid bar 4 is hung and is fixed between the actuating doors 2 of travel switch 5 and machine, the contact 6 that the length of three-dimensional bar 4 is slightly larger than travel switch 4 is the distance between contact 6 and gathering hole under reset mode, be that d1 is slightly larger than d2, above-mentioned small length difference has guaranteed when machine door 2 is closed, contact 6 actions of travel switch 5, power supply is switched on, and machine is normally worked.
As shown in Figure 1 when the actuating doors 2 of machine is in the state of closing, one end of three-dimensional bar 4 abuts against on door 2, and the other end is pressed against on the contact 6 of travel switch 5, contact 6 actions, and travel switch 5 is switched on, the normal operation of machine energising; The moment being opened at machine operation door 2, three-dimensional bar 4 has lost External Force Acting, and under the effect of travel switch 5 contained springs, the contact 6 of travel switch 5 automatically resets, and travel switch 5 disconnects, machine power-off.
It should be noted in the discussion above that the utility model is not limited to the disclosed embodiments, but can in the scope of described claim, change and revise.
Claims (2)
1. a switch gearing device, comprises travel switch and three-dimensional bar, it is characterized in that: described travel switch is arranged on the machine inner casing on actuating doors opposite, is connected with the high voltage equipment of machine intimate; Described three-dimensional bar is insulating material, and is provided with insulating trip at two ends, and described three-dimensional bar is arranged between travel switch and the actuating doors of machine.
