Abstract
Disclosed is a switch shutting mechanism for a coal cutter, comprising an installing plate, a switch handgrip assembly hinged to the installing plate, and a fixed base arranged upon the installing plate, wherein one end of a rotation self-locking handgrip assembly is inserted in the fixed base and freely rotates inside the fixed base; and the rotation self-locking handgrip assembly and the switch handgrip assembly mutually interfere with each other during the rotating process. According to the utility model, two self-locking surfaces of the switch handgrip assembly and the gap in the rotation self-locking handgrip assembly cooperate with each other to form shutting. When the rotation self-locking handgrip assembly is at operation, the switch can be operated to start and stop. When the rotation self-locking handgrip is put down, a shutting shaft is utilized for shutting the rotation interference of the switch handgrip assembly.
Description
Technical field
The utility model relates to a kind of device that prevents the coal-winning machine misoperation, is specifically related to a kind of latch switch.
Background technology
Coal-winning machine is the nucleus equipment of fully-mechanized mining working, and the workplace is all underground, and it is abominable that the machine of coal-winning machine carries the surrounding enviroment of frequency converter outward, and uneven such as base plate, peripheral roadway support is not in place etc.And mainly from everyone mine lamp of carrying, the visual field is bad at down-hole visual light.If facility switching does not have locking device, be very easy to equipment misoperation or the switch that collides with because of carelessness causes the illegal switching on and shutting down of equipment etc., thereby cause the accident.
The utility model content
The technical problems to be solved in the utility model is that coal-winning machine easy misoperation when underground activities causes the accident, and a kind of coal-winning machine circuit breaker lock structure that prevents misoperation is provided.
The technical solution of the utility model realizes in the following manner: a kind of coal-winning machine circuit breaker lock structure, comprise mounting panel, be hinged with the switch handle assembly on the mounting panel, mounting panel is provided with holder, rotary self-locking handle assembly one end is plugged in the holder and rotates freely in holder, mutually interferes when rotary self-locking handle assembly and the rotation of switch handle assembly.
Described rotary self-locking handle assembly comprises rotary handle and latch shaft, and latch shaft is provided with breach, and latch shaft is plugged in the holder, and latch shaft one end is provided with set bolt.
Described switch handle assembly comprises the switch handgrip, and the switch handgrip links to each other with reference column, and reference column links to each other with the handgrip axle, and the switch handle assembly is hinged on the mounting panel by the handgrip axle, and reference column is provided with cooperate with breach two from locking face.
Described breach is the bar v notch v, reference column be cut out on the cylindrical column that two pieces form from locking face.
In the utility model, two of the switch handle assembly from the locking face formation locking that matches with breach on the rotary self-locking handle assembly, when work during the rotary self-locking handgrip, and the operable switch start and stop; When putting down the rotary self-locking handgrip, by latch shaft locking is carried out in the rotation interference of switch handle assembly.

Embodiment
As shown in drawings, a kind of coal-winning machine circuit breaker lock structure, comprise mounting panel 4, be hinged with switch handle assembly 3 on the mounting panel 4, mounting panel 4 is provided with holder 2, rotary self-locking handle assembly 1 one ends are plugged in the holder 2 and rotate freely in holder, mutually interfere when rotary self-locking handle assembly 1 and 3 rotation of switch handle assembly.
Described rotary self-locking handle assembly 1 comprises rotary handle 1-1 and latch shaft 1-2, and latch shaft 1-2 is provided with breach 1-3, and latch shaft 1-2 is plugged in the holder 2, and latch shaft 1-2 one end is provided with set bolt 5.In the time of assembling, holder 2 is welded on the mounting panel 4, and latch shaft 1-2 is plugged in the holder 2, and the set bolt 5 of screwing on afterwards gets final product.
Described switch handle assembly 3 comprises switch handgrip 3-1, switch handgrip 3-1 links to each other with reference column 3-2, reference column 3-2 links to each other with handgrip axle 3-3, and switch handle assembly 3 is hinged on the mounting panel 4 by handgrip axle 3-3, and reference column 3-2 is provided with cooperate with breach 1-3 two from locking face 3-4.
Described breach 1-3 is the bar v notch v, reference column 3-2 be cut out on the cylindrical column that two pieces form two from locking face 3-4.
When the utility model used, switch handle assembly 3 was connected with electric elements on the coal-winning machine, when switch handle assembly 3 rotates, can carry out the switching function of electric component.
The utility model specific works process is as follows:
1. as shown in Figure 1, switch handle assembly 3 is in the position of " dividing ", and rotary self-locking handle assembly 1 naturally droops under action of gravitation, and switch handle assembly 3 can not be realized rotary manipulation at this moment, has formed blocking.
2. as shown in Figure 3, manually pick up rotary self-locking handle assembly 1, the breach 1-3 on this moment latch shaft 1-2 down, switch handle assembly 3 can rotate.
3. such as Fig. 4, rotary switch handle assembly 3 so that reference column 1-3 rotates at breach 1-3, can carry out switching manipulation to coal-winning machine.
4. as shown in Figure 5, rotary switch handle assembly 3 is in the position of " closing ", unclamps rotary self-locking handle assembly 1, and it is naturally drooped under Action of Gravity Field, switch handle assembly 3 formation lockings this moment.
When the utility model can prevent improper operation coal-winning machine grip switches, misoperation or cause because of carelessness the illegal switching on and shutting down of equipment.The utility model on being used in coal-winning machine, also can be used on other equipment, prevent that misoperation from bringing various harm.When the switch handle assembly is in the opening and closing two states, all can't operate the coal-winning machine switch, only have when breach 1-3 down, when switch handle assembly 3 can rotate freely, just can operate the coal-winning machine switch.
