Abstract
The utility model relates to a mining flame-proof vacuum feeder switch locking device comprising a main locking device body. The main locking device body is characterized in that a baffle plate and two side plates form a U-shaped groove structure; pin holes are respectively arranged at the two side plates, wherein the centers of circles of the two pin holes are at the same straight line; and a positioning pin passes through the two pin holes and one end of the positioning pin is provided with a lock hole for locking. With utilization of the technical scheme, when a switch is at a power failure position, a latching rod of the switch can be screwed to a locking position to seal the latching rod, thereby preventing the latching rod of the switch from being screwed by mistake by someone with utilization of a flat head screwdriver. When electrical maintenance is carried out, the latching rod is screwed to a right position after the power failure; the device is buckled at the switch, the positioning pin is arranged, and the device is locked by a lockset; and the key is taken by the worker, so that power transmission by mistake by others can be avoided and thus double security is realized. Therefore, a phenomenon that power transmission by mistake is carried out because the operator and the maintenance man are not at the same position can be avoided and power transmission can not be realized as long as the locking device is not removed. The provided locking device with the characteristics of simple structure and novel design can provide safety guarantee for the underground electromechanical maintenance personnel.
Description
Technical field
The utility model relates to a kind of flame-proof mine vacuum feed switch locking device.
Background technology
KBZ-400 1140(660) the flame-proof mine vacuum feed switch is extensive use of in the colliery.Because it integrates defencive function and tool wind-powered electricity generation gas shutting functions such as overcurrent, short circuit, overload, under-voltage, overvoltage, the phase failure, three-phase equilibrium.Be applicable to and contain methane mixture gas, have under the explosion hazard coal mine.Feeding switch is mainly exchanging 50Hz, rated voltage is 1140V, 660V, rated current is 400, in the not directly grounded power supply grid of 200A neutral point, as distribution master switch, distribution branch switch, also can be used as the not usefulness of Fraquent start control of large capacity motor.
KBZ400 type explosion-proof feeding switch is extensive use of in the ore deposit, colliery, because it has good performance.Integrate short circuit ground protection, earth leakage search/lockout, open phase protection, the down-hole is as master switch, or switch-dividing.Since the underground work circumstance complication, the ground humidity, and reasons such as electric equipment frequent starting usually cause 400 type switches and relevant electric equipment appearance fault in various degree.When maintenance, stipulate relevant device to be had a power failure locking according to " safety regulations in coal mine ", and hold the warning sign of " someone works, and forbids sending ", and to the power failure of upper level master switch, locking.In order to guarantee maintenance work personnel's safety, according to the requirement of dynamo-electric portion, will be with 400 type feeding switchs, after deadlock lever is locked, i.e. the dried power failure position of getting to of locking, add again one the cover deadlock lever the device that latches, it is perfectly safe to guarantee that safety goes up, because not at same position, the misdelivery electricity can cause unsafe factor to the maintenance personal, has very big potential safety hazard with the dynamo-electric chamber of placing 400 type feeding switchs in the place of maintenance electric equipment.
The utility model content
The purpose of this utility model is to solve the above-mentioned technical problem that exists in the prior art, and a kind of flame-proof mine vacuum feed switch locking device is provided.
For achieving the above object, the technical solution adopted in the utility model is as follows:
The utility model flame-proof mine vacuum feed switch locking device, comprise the locking device main body, the locking device main body is formed U-shaped groove structure by baffle plate and two side plates, be respectively equipped with pin-and-hole at biside plate, the center of circle of two pin-and-holes is on same straight line, alignment pin passes two pin-and-holes, and an end of alignment pin is provided be used to the lockhole of locking.
The utility model preferably is provided with draw-in groove in the end of biside plate.
Adopt the technical solution of the utility model, when switch is in the power failure position, the deadlock lever of switch can be screwed to locked position of coupler, and deadlock lever is sealed, and has avoided the human flathead screwdriver, and mistake is turned on the pass deadlock lever.When being engaged in electrical repair, after having a power failure deadlock lever is screwed to the position, as long as this device is buckled, put on alignment pin, and pin with lockset, hold key properly, other people just can not misdeliver, double insurance, avoid because of operating personnel and maintenance personal not at the same position electricity of misdelivering, only otherwise going this device just to send does not power on.
The utility model is simple in structure, modern design, and dynamo-electric maintenance personal provides safety guarantee to the down-hole.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the left view of the locking device main body in the utility model.
Embodiment
The utility model flame-proof mine vacuum feed switch locking device, comprise locking device main body 7, the locking device main body is formed U-shaped groove structure by baffle plate and two side plates, is respectively equipped with pin-and-hole at biside plate, and left plate is provided with left pin-and-hole 3, right plate is provided with right pin-and-hole 5, the center of circle of two pin-and-holes is on same straight line, and alignment pin 4 passes two pin-and-holes, and is provided with pad 2, one end of alignment pin is provided be used to the lockhole 6 of locking, and the other end of alignment pin is provided with drop handle 1.Be provided with draw-in groove 8 in the end of biside plate.
Specific embodiment is: groove width was the U-shaped groove of 30mm in steel plate symmetry 3mm is thick, specification 150 * 150mm was processed into, specification is 150 * 60 * 30, as the device main body part that latches, again at two centers of sidetracking up and down of U-shaped groove at a straight line, and anisometric two holes, the center of circle is at horizontal 35mm, vertical 25mm place, the hole of the hole of a φ 17 of last sidetracking and a φ 22 of following sidetracking, be used for wearing alignment pin, the specification of alignment pin is φ 20, the long 70mm of bar, hole at the following drill with ferrule φ 10 of bar is used for adding lockset.Pin penetrates from macropore, passes aperture again, uses the plain washer transverse weld of φ 30 as back-up ring again, vertically welds the plain washer of a φ 30 again on the plain washer of transverse weld, as the handle of this device.At horizontal 10mm place, be processed into the location notch of the circuit breaker lock bar of u type with the steel plate of δ=3mm after processing, locate groove width 20mm, the degree of depth is 20mm, and reinforcement of weld, open 35 * 48 mouth at the vertical 102m of body place, welding a block specifications in body end again is 30 * 43 baffle plate.
