Abstract

The utility model relates to a main control cabinet of electric control equipment of an excavator, composed of a cabinet frame which is parallel with a cabinet door, a thyristor screen, an AC control screen installed in a cabinet frame, a regulating screen hinged on the cabinet frame, and a door lock. Elements on the three screens are all installed at the front of the screens. The utility model changes the existing four screens in the control cabinet into three screens, reduces connecting wires among screens, and enhances using reliability; the elements are arranged at the front of the screens, the use and the repair are convenient; the structure of the opening and closing plate door lock can open the cabinet door and eliminate failure at any time.

Description

Excavator control panel main control cabinet

The utility model relates to a kind of excavator control panel main control cabinet, particularly a kind of mine excavator electric control cabinet.

At present, the main control cabinet of mine excavator is formed by regulating screen, brilliant lock screen, DC control screen and AC panel four parts, and its layout is unreasonable, line is many between screen, and the transition binding post increases, and intersects in length and breadth, overlaps layer by layer, because terminal is many, the fault point increases, and influences reliability; Preceding, the screen back installation of its components and parts employing screen changes, keeps in repair the back door that must open cabinet, extremely inconvenience in the on-the-spot use.

The purpose of this utility model is to provide a kind of connection and reasonable arrangement, and line is few between screen, excavator control panel main control cabinet easy to maintenance.

The purpose of this utility model realizes in the following manner: excavator control panel main control cabinet, comprise tank bracket 1, be articulated in the cabinet door on the tank bracket 1, it also comprises AC panel 21, the thyristor screen 22 that is loaded in the tank bracket 1 and regulates screen 3, AC panel 21, thyristor screen 22 all parallel cabinet doors are fixed in the tank bracket 1, regulate screen 3 and are positioned at crystalline substance and explain the parallel cabinet door in tube panel 22 the place aheads and be articulated on the tank bracket 1.Line-breaker 35, grounding assembly 36, secondary D.C. contactor 37, A.C. contactor 28, thermal relay 39, auxiliary relay 40 are housed on the AC panel 21; On the thyristor screen 22 stabilized voltage power supply assembly 25, three phase rectifier axle assemble 26, magnetic trigger 27, square wave power assembly 28, half control bridge circuit breaker 29, half control axle assemble 30, main D.C. contactor 31, JT3 relay 32 and phase sequence phase failure assembly 33 are housed; Regulate and rotary system adjustable plate 4, revolution detection terminal 5, revolution semiconductor subassembly 6, revolution adjusting knob plate 7, pushing system adjustable plate 8, pushing detection terminal 9, pushing semiconductor subassembly 10, pushing adjusting knob plate 11, elevator system adjustable plate 12 to be housed on the screen 3, to promote detection terminal 13, to promote semiconductor subassembly 14, promote adjusting knob plate 15, and before first device assembly of three screens is loaded on screen.Be equipped with on the cabinet door on switchboard door lock 20, the tank bracket 1 and mutually lockhole should be arranged.

The utility model will have now to be regulated screen, brilliant lock screen, DC control screen and AC panel four parts and forms to change into and regulate screen, brilliant lock screen and AC panel three parts and form in the main control cabinet of mine controller, reduce line between screen, improved the reliability of using, arrange before the components and parts screen, use easy to maintenancely, the switchboard door lock can be opened the cabinet door at any time and fix a breakdown.Behind the screen components and parts are installed all before the screen in the existing main control cabinet, the back door that change and repair must be opened cabinet in on-the-spot the use, extremely inconvenient, the cabinet door fixedly be close to screw, once be in accident condition, affect the time of opening the door adversely and cause the accident expansion.

Accompanying drawing has provided embodiment of the present utility model.

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model structural representation vertical view

Fig. 3 is the utility model thyristor screen and AC panel floor plan;

Below in conjunction with accompanying drawing the utility model is described in further detail:

With reference to Fig. 1, the utility model is made up of tank bracket 1, cabinet door, adjusting screen 3, thyristor screen 22, AC panel 21, with reference to Fig. 2, Fig. 3, thyristor screen 22, AC panel 21 all are parallel to the cabinet door and are fixed in the tank bracket 1, and line-breaker 35, grounding assembly 36, secondary D.C. contactor 37, A.C. contactor 28, thermal relay 39, auxiliary relay 40 are housed on the AC panel 21; On the thyristor screen 22 stabilized voltage power supply assembly 25, three phase rectifier axle assemble 26, magnetic trigger 27, square wave power assembly 28, half control bridge circuit breaker 29, half control axle assemble 30, main D.C. contactor 31, JT3 relay 32 and phase sequence phase failure assembly 33 are housed; Regulate the place ahead that screen 3 is positioned at thyristor screen 22, being parallel to the cabinet door is articulated on the tank bracket 1, regulate and rotary system adjustable plate 4, revolution detection terminal 5, revolution semiconductor subassembly 6, revolution adjusting knob plate 7, pushing system adjustable plate 8, pushing detection terminal 9, pushing semiconductor subassembly 10, pushing adjusting knob plate 11, elevator system adjustable plate 12 to be housed on the screen 3, to promote detection terminal 13, to promote semiconductor subassembly 14 cabinets and promote adjusting knob plate 15, before first device assembly of three screens all is loaded on screen, convenient for maintaining.Cabinet door of the present utility model has four fans according to the layout of three screens, 2 is preceding left-hand door, 16 is that preceding middle door, 18 is upper right door, 19 is the bottom right door, 17,20 be on door lock, the tank bracket 1 lockhole should be arranged, left-hand door 2 can overhaul easily and regulate screen 3 before opening, will regulate screen 3 and before in 16 open to the left and right sides, can overhaul thyristor screen 22, open upper

right door

18 and 19 at bottom right door and can overhaul AC panel 21.Door lock 20 on the cabinet door is the switchboard door lock.23 is binding post among Fig. 3, and 24 is wiring groove.
