Background

The mining explosion-proof feed switch is mainly used in each underground operation area, and is mainly used for controlling the starting and stopping of each electric device, so that the operation of various devices is facilitated. In the normal production process, because the production rhythm is nervous, when the load electrical equipment that flame proof feed switch was taken a fault and need overhaul or move and establish subordinate's equipment cable, the operation personnel sometimes because carelessness carelessly maloperation power isolator, or because the improper accident touches isolator, lead to the mistake power transmission, cause the electric shock accident.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a mining flame-proof type feed switch's blocking device can effectively avoid the maloperation, stops the occurence of failure, guarantees workman's safety under the ore deposit.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a mining flame-proof type feed switch's blocking device, includes flame-proof casing, switch door, fastener, handle, gear, inserted bar, inserts the nose and insert the ring, its characterized in that: the novel explosion-proof door is characterized in that a fastener is fixed to the side face of the door, the inserting nose is welded to the fastener, the handle is installed on the explosion-proof shell, the gear is fixedly connected with the handle, the tail end of the inserting rod is a rack, the rack is meshed with the gear and connected with the gear, a clamping strip is arranged at the head end of the inserting rod, the clamping strip is connected with the head end of the inserting rod through a pin shaft, the inserting ring is fixed to the explosion-proof shell, and the inserting rod can penetrate through the inserting ring and is inserted into the inserting nose.

The gear and the handle are arranged on the same shaft and can synchronously rotate.

The number of the insert rings is two.

The clamping strip can do circular motion by taking the pin shaft as the center.

When the switch door is closed, the rotating handle is switched on, the gear rotates along with the rotating handle, the insertion rod moves leftwards through the transmission of the gear and the rack and is inserted into the insertion nose, and then the clamping strip can be rotated to lock the position of the current handle; when the switch door is to be opened, the clamping strip needs to be rotated firstly to enable the clamping strip to be flush with the inserted link, then the handle is rotated to open the switch, the gear rotates along with the clamp, the inserted link moves rightwards through the transmission of the gear and the rack, and the switch door can be opened at the moment.

The utility model has the advantages that: simple structure, easy to operate can effectively avoid the operation personnel carelessness to careless or unexpected touch isolator, has stopped the accident that the maloperation caused, has guaranteed workman's under the ore deposit safety.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1 and fig. 2, a locking device of mining flame-proof type feed switch, including flame-proof casing 1, switch door 2, fastener 3, handle 4, gear 5, inserted bar 6, insert nose 7 and insert ring 9, its characterized in that: the side of switch door 2 is fixed with fastener 3, insert the welding of nose 7 on fastener 3, handle 4 is installed on flame proof shell 1, gear 5 and handle 4 fixed connection, the tail end of inserted bar 6 is rack 8, rack 8 with the gear 5 meshing is connected, the head end of inserted bar 6 has a card strip 10, card strip 10 is connected through round pin axle 11 with the 6 head ends of inserted bar, insert ring 9 is fixed on flame proof shell 1, inserted bar 6 can pass insert in nose 7 through insert ring 9.

The gear 5 and the handle 4 are arranged on the same shaft and can rotate synchronously.

The number of the insert rings 9 is two.

The clip strip 10 can make circular motion by taking the pin shaft 11 as the center.

When the switch door 2 is closed, the rotating handle 4 is switched on, the gear 5 rotates along with the switch door, the inserted link 6 moves leftwards through the transmission of the gear 5 and the rack 8 and is inserted into the inserted nose 7, and then the clamping strip 10 can be rotated to lock the position of the current handle 4; when the switch door 2 is to be opened, the clamping strip 10 needs to be rotated firstly to enable the clamping strip 10 to be flush with the inserted link 6, then the handle 4 is rotated to be opened, the gear 5 rotates along with the clamping strip, the inserted link 6 is enabled to move rightwards through the transmission of the gear 5 and the rack 8, and the switch door 2 can be opened at the moment.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
