Description

Technical Field

[0001] This utility model relates to the field of switch cabinets, and in particular to an auxiliary installation device for equipment inside a switch cabinet. Background Technology

[0002] A switchgear is an electrical device. External power lines first enter the main control switch inside the cabinet, then the branch control switches, with each branch circuit configured according to its needs. Examples include instruments, automatic control systems, motor magnetic switches, various AC contactors, etc. Some switchgear also have high-voltage and low-voltage compartments, and high-voltage busbars, such as in power plants. Some also have underfrequency load shearing features to protect key equipment. Current installation methods require separate removal of terminal fixing screws, which is inefficient. Utility Model Content

[0003] In order to overcome the shortcomings of low terminal disassembly efficiency in existing switchgear, the technical problem of this utility model is to provide an auxiliary installation device for equipment inside the switchgear.

[0004] The technical implementation of this utility model is as follows: an auxiliary installation device for equipment inside a switch cabinet, including an operating frame. Three through holes are equidistantly arranged on the operating frame, and each through hole is rotatably connected to a screwdriver bit. The front end of each screwdriver bit extends to the front of the operating frame. Gears B are keyed to the rear ends of the screwdriver bits on the left and right sides. Two gears A are keyed to the rear end of the middle screwdriver bit. Gears A and B are respectively connected by toothed belts. The rear side of each gear A is connected to the front end of a connecting rod via a spline. A torsion bar is fixedly connected to the rear end of the connecting rod. By holding the screwdriver bit and aligning it with the switch cabinet terminal fixing screw, rotating the torsion bar causes the connecting rod to drive gears A via toothed belt transmission, causing the three screwdriver bits to rotate synchronously, thereby completing the disassembly and installation of multiple switch cabinet terminal fixing screws.

[0005] Furthermore, it also includes a limiting rod. The upper left and right sides of the operating frame are provided with sliding grooves. The limiting rod is slidably connected in the sliding grooves. A clamping block A is fixedly connected to the top of the limiting rod. A spring is sleeved on the limiting rod. One end of the spring is fixedly connected to the operating frame, and the other end of the spring is fixedly connected to the limiting rod. Clamping blocks B are fixedly connected to the bottom left and right sides of the operating frame. Both clamping blocks A and clamping blocks B are L-shaped.

[0006] Furthermore, it also includes a brake lever, with the front end of the brake lever snapped into the rear side of the operating frame. A brake block is provided on the rear end of the brake lever, and the brake block contacts the outer peripheral surface of the right gear B, achieving braking through friction to prevent the main gear B from rotating when the device is not in use.

[0007] Furthermore, it also includes coil frames, with three coil frames fixedly connected to the bottom of the operating frame. The coil frames are used to fix the wires when installing the switch cabinet terminals.

[0008] Furthermore, it also includes an anti-slip block, which is provided on the clamping block B.

[0009] Furthermore, it also includes a stop, wherein a limiting stop is fitted on the bit to restrict the axial movement of the bit.

[0010] This utility model has the following advantages: 1. By holding the bit and aligning it with the fixing screw of the switch cabinet terminal, rotating the torsion bar causes the connecting rod drive gear A to drive the three bits to rotate through the toothed belt, thereby completing the disassembly and installation of the fixing screws of multiple switch cabinet terminals, which greatly improves the disassembly efficiency of switch cabinet terminals.

[0011] 2. By pulling up the clamping blocks A on both sides, the spring is stretched to raise the clamping blocks A, widening the distance between them and the clamping block B, and the entire device is snapped into the terminal block. This ensures that the L-shaped structures of the clamping blocks A and B fit the upper and lower edges of terminals of different sizes, which can accommodate the installation of terminals of different sizes and ensures the device is stably fixed.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example: An auxiliary installation device for equipment inside a switchgear, such as... Figure 1-3As shown, the device includes an operating frame 1, a bit 2, gear A3, gear B301, a toothed belt 4, a connecting rod 5, and a torsion bar 6. The operating frame 1 has three through holes arranged at equal intervals, and the bit 2 is rotatably connected to each of the through holes. The front end of the bit 2 extends to the front of the operating frame 1. The rear ends of the bit 2 on the left and right sides are keyed to the gear B301. The rear end of the bit 2 in the middle is keyed to two gears A3. The two gears A3 are respectively connected to the left and right gears B301 with the toothed belt 4. The rear side of the gear A3 is connected to the front end of the connecting rod 5 through a spline. The rear end of the connecting rod 5 is fixedly connected to the torsion bar 6. The system also includes a limiting rod 7, a spring 8, and a clamping block. The upper left and right sides of the operating frame 1 are provided with sliding grooves, within which the limiting rod 7 is slidably connected. A clamping block A9 is fixedly connected to the top of the limiting rod 7. The spring 8 is sleeved on the limiting rod 7, with one end of the spring 8 fixedly connected to the operating frame 1 and the other end fixedly connected to the limiting rod 7. Clamping blocks B901 are fixedly connected to the bottom left and right sides of the operating frame 1. Both clamping blocks A9 and B901 are L-shaped. The system also includes a brake rod 10 and a brake block 11. The front end of the brake rod 10 is snapped into the rear side of the operating frame 1, and the rear end of the brake rod 10 is provided with a brake block 11, which contacts the outer circumferential surface of the gear B301 on the right side. Finally, an anti-slip block 13 is provided on the clamping block B901.

[0018] Move the device to the terminal block installation position in the switch cabinet, aligning the front ends of the three bit 2 with the screws to be removed / installed. Pull upwards the clamping blocks A9 on both sides, stretching the spring 8 to raise the clamping blocks A9, increasing the distance between them and the clamping block B901. Insert the entire device into the terminal block, ensuring that the L-shaped structures of clamping blocks A9 and B are respectively aligned with the upper and lower edges of the terminal block. Slowly release the limiting rod 7; the spring 8 returns to its original position, pushing the clamping block A9 downwards, clamping the terminal block together with the clamping block B901. At this time, the anti-slip block 13 increases friction, ensuring the device is stably fixed. Remove the brake rod 10 from the operating frame 1, separating the brake block 11 from the outer circumference of the gear B301, releasing the friction braking state. The operator holds the torsion bar 6 and applies a rotational torque. The power is transmitted to the gear A3 via a spline connection. The gear A3 drives the gears B301 on both sides to rotate synchronously through the toothed belt 4, causing the three screwdriver bits 2 to rotate at the same speed. The screwdriver tip at the front end of the screwdriver bit 2 engages with the groove on the screw head, and the screw is disassembled by rotating counterclockwise. The screw is then simultaneously ejected along with the screwdriver bit 2. After the operation is completed, the brake lever 10 is engaged with the operating frame 1, causing the brake block 11 to lock the gear B301, preventing the screwdriver bits 2 from rotating accidentally when not in operation.

[0019] like Figure 1 and Figure 2 As shown, it also includes coil holders 12, three of which are fixedly connected to the bottom of the operating frame 1 for fixing the wires when installing switch cabinet terminals. It also includes a stop block 14, which is fitted onto the bit 2 to limit its movement.

[0020] When removing the terminal, the wire is wound into the slot of the coil holder 12. The number of turns can be adjusted as needed to prevent the wire from becoming tangled. The stop block 14 is used to limit the axial movement of the bit 2.
