Description

High-voltage switchgear cabinet door opening device

technical field

The utility model relates to the technical field of opening a high-voltage switch cabinet door, in particular to a high-voltage switch cabinet door opening device.

Background technique

Substation high-voltage switchgear is one of the main equipment in the substation. Its main function is to install and arrange the circuit breaker, isolating switch or trolley switch in the substation in the high-voltage switchgear. In order to ensure the effective safety distance between various electrical equipment, and consider factors such as ventilation, heat dissipation, and convenient maintenance, the height of the high-voltage switchgear is generally very high (usually more than 3 meters). A high-voltage switchgear is generally divided into protection compartments, switch compartments, cable compartments, etc., and arranged in sequence from top to bottom. Each compartment has an independent cabinet door. The cabinet doors of the higher compartments are difficult for workers of normal height to reach. , generally need to stand on the ladder to open the cabinet door. The cabinet door of the lower floor is closed by the switch cabinet door lock, but the cabinet door of the uppermost floor is locked by screws. At present, when opening the door of the high-voltage switch cabinet, tools such as screwdrivers and small wrenches are often used while standing on the ladder. When opening the door of the high-voltage switchgear with the help of a ladder, the ladder leans against the high-voltage switchgear and it is easy to damage the high-voltage switchgear, and the ladder is easy to touch the high-voltage equipment during transportation, which increases the risk factor.

Detailed ways

As shown in Figures 1 to 7, the utility model mainly includes a base 1, a column 2, a support frame 3, a lifting assembly, a rotating drive assembly and a screwdriver 7, and the utility model is described in detail below in conjunction with the accompanying drawings.

As shown in Figure 1, the base 1 is a collective of the utility model, two pairs of universal wheels 11 are arranged at the bottom of the base, a storage battery 12 is arranged on one side of the top of the base, and a vertically placed The column 2 is provided with a vertical support frame 3 on the top of the column. As shown in Figure 2, the support frame is an "I"-shaped structure, which can be connected by two parallel rectangular plates and a vertical bar vertical to the rectangular plate. fixed connection. A pair of guide columns 32 are arranged on the support frame, and the two guide columns are arranged on both sides of the vertical bar, and the upper and lower ends of the guide columns are fixedly connected with the corresponding rectangular plates. Two connecting rods 31 are fixed on the support frame, vertical racks 4 are fixed on the two connecting rods, a support 5 is slidably installed on the rack, the support can slide in the vertical direction, and is fixedly installed on the support There is a first motor 53, and a gear 52 is fixedly installed on the output shaft of the first motor, and the gear meshes with the rack. When the first motor outputs rotational motion, the gear can be driven to rotate, and the gear and the rack are meshed and matched to drive The gear walks on the rack, and finally the drive bracket slides up and down relative to the rack. In order to increase the stability when the support slides up and down, two cross bars 51 are fixed on the support, and a slide block 511 is fixed at the end of each cross bar. The two slide blocks are respectively slidably connected with two guide columns. The lifting of the support provides guidance. The support, the first motor, the gear, the rack, the slide block, the cross bar and the guide column constitute the lifting assembly.

As shown in Figure 3, a second motor 54 is fixed on the side of the support, the second motor is a stepper motor, and a turntable 55 is fixed on the output shaft of the second motor, the turntable is a circular metal plate, and the second motor outputs The shaft is fixedly connected to the center of the turntable. A first swing link 61 is hingedly installed at the edge of the turntable, and the swing plane of the first swing link is perpendicular to the plane where the turntable is located. As shown in FIGS. 4 and 5 , a second swing rod 62 is hingedly mounted on the free end of the first swing rod, and the other end of the second swing rod is hingedly mounted on the screwdriver 7 . As shown in Figure 6, the main body of the screwdriver is a circular metal rod, and the middle part of the screwdriver main body is provided with an external thread 72. The active end of the screwdriver main body is cross-shaped or flat-mouthed, and a magnet is arranged at the active end of the screwdriver. In order to absorb the screw, the active end of the screwdriver body acts on the screw to remove the screw. An ear plate 73 is provided on the outer wall of the driving end of the screwdriver body, and the screwdriver is hingedly connected to the second swing rod through the ear plate. The active end of the screwdriver main body is provided with a protective plate 71, as shown in Figure 7, the protective plate is a bowl-shaped rubber piece, and the protective plate is sleeved on the screwdriver main body and relatively fixed with the screwdriver main body. A main support 57 is fixedly installed on the support, and the main support is a "∟" shaped metal piece. One end of the main support is fixedly connected with the support, and a horizontally placed guide sleeve 56 is fixed on the other end of the main support. Internal thread, the guide sleeve is threadedly connected with the middle part of the screwdriver; in this way, when the screwdriver rotates in the guide sleeve, it also moves axially relative to the guide sleeve. Since the first swing link is hingedly connected to the second swing link, the first swing link is hingedly connected to the turntable, and the second swing link is hingedly connected to the screwdriver, the screwdriver can rotate and move axially along the guide sleeve. When the screw is unloaded, the screw moves outward, so the screwdriver moves along the axis of the guide sleeve to the side closer to the bracket. In order to ensure the stability of the guide sleeve, an oblique support 58 is provided between the guide sleeve and the main support. Both the first motor and the second motor are electrically connected to the storage battery through wires. The second motor, the first fork, the second fork, the turntable and the guide sleeve constitute the rotary drive assembly.

The working process of the utility model is described below. First, the whole device is moved to the front of the switch cabinet to be opened, and then the first motor is driven to make the bracket rise until the screwdriver and the screw to be unloaded are on the same straight line, and then the second A motor stops moving. The second motor is driven to rotate the turntable. At this time, the turntable drives the screwdriver to rotate relative to the guide sleeve through the first swing rod and the second swing rod. The active end of the screwdriver acts on the screw to make the screw rotate. Because the guide sleeve is fixed on the bracket and the guide sleeve is provided with internal threads, and the screwdriver is provided with external threads, therefore, the screwdriver also moves axially relative to the guide sleeve while rotating. Since the active end of the screwdriver is provided with a magnet to hold the screw, the screwdriver holds the screw and drives the screw to move outward during the rotation. In order to realize the unloading of the screws on the switch cabinet door, when the second motor operates, it should ensure that the screwdriver moves to the side close to the support. After one screw is removed, the second motor rotates in the opposite direction, resetting the screwdriver. The protective plate is a rubber part, which can provide support for the screw. On the one hand, the active end of the screwdriver absorbs the screw, and on the other hand, the protective plate supports the screw to prevent the screw from falling on the ground.
