Abstract

The utility model relates to a switch cabinet, in particular to an impelling mechanism for low-pressure draw-out switch cabinets, including an impelling wheel, a bracket, a curved trough set on the external circle of the impelling wheel, and a tool hole set on one end of the impelling wheel matching with the operational tool. The impelling wheel is movably installed on the bracket; the bracket is fixedly connected with the drawer motherplate; the impelling wheel together with the impelling chassis fixed on the clapboard of the switch cabinet, form a rotary displacement match through the curved trough on the impelling wheel. Though adding the impelling mechanism and using the T-shaped handle and other operational tools, the impelling wheel can be rotated to drive the whole drawer in and out; and at the same time, with the location display, the drawer location can be known outside the switch cabinet. The impelling mechanism has simple structure, small impelling torque and convenient operation, particularly applicable to MMC cabinets and other cabinets.

Description

The propulsive mechanism of low pressure draw out switchgear cabinet

Technical field

The utility model relates to a kind of switch cubicle, relates in particular to a kind of propulsive mechanism of low pressure draw out switchgear cabinet.

Background technology

Along with MNS low pressure draw out switchgear at home overall application in recent years, become the main product of domestic low pressure draw out switchgear, be widely used in the distribution system of industrial and mining enterprises such as land usefulness, power station, nuclear power station, peculiar to vessel, petrochemical industry.The standard scheme capacity of MCC cabinet has been difficult to satisfy client's demand among the MNS of prior art; The functional unit of big capacity scheme (400A and above loop) often occurs, and the quantity of contact has reached 24 at most.Switch cubicle is separated into several spaces by dividing plate, and a drawer is set in each space, when switch cubicle uses, drawer must insert in the switch cubicle, but the insertion of drawer or extract out to need adopt the manpower direct control, is difficult to reach pass in and out requirement smoothly, it is loaded down with trivial details that use becomes, very waste of manpower and man-hour.

Summary of the invention

The purpose of this utility model is at the deficiencies in the prior art, provide a kind of simple to operate, pass in and out the propulsive mechanism of low pressure draw out switchgear cabinet smoothly.

For achieving the above object, the utility model adopts a kind of propulsive mechanism of low pressure draw out switchgear cabinet, propulsive mechanism comprises propelling wheel, support, advance the cylindrical of wheel to be provided with curved groove, advance wheel one end to be provided with the tooling hole that is complementary with operation tool, advance wheel to be arranged on versatilely on the support, support is fixedlyed connected with drawer-bottom board, advances wheel to cooperate with advance seat formation swing offset on the dividing plate that is fixed on switch cubicle by the curved groove on it.

For in to the drawer operation, the position that advances the wheel place is locked, the sidewall that the utility model further is set to support is provided with align member, align member comprises the hoodle cover, adjustment bolt, back-moving spring, hoodle are successively set in the hoodle cover, the relevant position is provided with location hole on the propelling wheel, and location hole constitutes the location with align member and cooperates.

In order to show the position of drawer in switch cubicle, the utility model further is set to advance on the cylindrical of the tooling hole on the wheel and is arranged with the position display plate, position indication on it is complementary with the position of detent mechanism locking, also has the locking closure that cooperates with tooling hole on the position display plate.

The utility model just provides a kind of propulsive mechanism of low pressure draw out switchgear cabinet, propulsive mechanism comprises propelling wheel, support, advance the cylindrical of wheel to be provided with curved groove, advance wheel one end to be provided with the tooling hole that is complementary with operation tool, advance wheel to be arranged on the support versatilely, support is fixedlyed connected with drawer-bottom board, advances wheel to cooperate with advance seat formation swing offset on the dividing plate that is fixed on switch cubicle by the curved groove on it.By setting up propulsive mechanism, utilize operation tools such as T type handle, rotate and advance the whole drawer propelling of wheel drive, extract out, simultaneously the position display plate is arranged again, can outside switch cubicle, just know the residing position of drawer.Propulsive mechanism is simple in structure, and boost torque is little, and is easy to operate, and the propulsive mechanism of this class is specially adapted to this class cabinet of MCC.

Fig. 2 is the utility model embodiment side structure schematic diagram.

Fig. 3 is the structural representation that the utility model embodiment combines with drawer-bottom board.

Embodiment

As Fig. 1,2, shown in 3, specific embodiment of the utility model is a kind of propulsive mechanism of low pressure draw out switchgear cabinet, propulsive mechanism 1 is arranged on the drawer-bottom board 2 of switch cubicle, propulsive mechanism 1 comprises advancing takes turns 11, support 12, advance the cylindrical of wheel 11 to be provided with curved groove 111, the curve pattern of curved groove 111 can be calculated according to the shift length of drawer turnover, advance wheel 11 1 ends to be provided with the tooling hole 112 that is complementary with operation tool such as T type handle, advance wheel 11 to be arranged on versatilely on the support 12, support 12 is fixedlyed connected with drawer-bottom board 2, advance wheel 11 to constitute swing offsets by curved groove on it 111 and advance seat 31 on the dividing plate 3 that is fixed on switch cubicle and cooperate, generally drawer-bottom board 2 has 30mm apart from dividing plate 3.The sidewall of support 12 is provided with align member 4, align member 4 comprises hoodle cover 41, adjustment bolt 42, back-moving spring 43, hoodle 44 are successively set in the hoodle cover 41, and the relevant position is provided with location hole 113 on propelling wheel 11, and location hole 113 is located with align member 4 formations and cooperated.Be arranged with position display plate 5 on the cylindrical of tooling hole 112, the position indication on it is complementary with the position of detent mechanism 5 lockings, also has the locking closure 6 that cooperates with tooling hole 112 on the position display plate 5.

The purpose that the utility model is provided with align member 4 is in to the drawer operation, and the position that advances wheel 11 places is locked.Clockwise direction rotates T-handle 330 degree, when advancing wheel 11 to turn to " connection " position, can hear hoodle 44 location " click clatter " sound.And, can show the position of drawer in switch cubicle by position display plate 5 is set, have on the position display plate 5 " connection ", " separation ", " test " three position indications also have the operative orientation indication of propulsive mechanism.When drawer did not use, desirable operation tool down covered locking closure 6, prevents misoperation.

By setting up propulsive mechanism 1, utilize operation tools such as T type handle, rotate and advance the whole drawer propelling of wheel 11 drives, extract out, simultaneously position display plate 5 is arranged again, can outside switch cubicle, just know the residing position of drawer.Propulsive mechanism 1 is simple in structure, and boost torque is little, and is easy to operate, and the propulsive mechanism 1 of this class is specially adapted to this class cabinet of MCC.
