Description

Technical Field

[0001] This utility model belongs to the field of transfer vehicles, specifically relating to a transfer vehicle for high-voltage switchgear circuit breakers. Background Technology

[0002] The high-voltage switchgear consists of two main parts: a fixed cabinet and a removable high-voltage trolley circuit breaker. During the installation of the switchgear, workers need to use a transfer vehicle to send the trolley into the designated position inside the cabinet. During the maintenance of the switchgear, workers need to pull the trolley out of the cabinet and use the transfer vehicle to drag the high-voltage trolley circuit breaker out of the switchgear and transfer it to the designated position.

[0003] Because the bottom of the trolley is equipped with rollers for easy transport, the trolley may slip off the transport vehicle during transfer. Furthermore, moving the trolley from the transport vehicle into the cabinet and vice versa requires manual operation. Since high-voltage circuit breakers are heavy, even with rollers, moving the trolley is time-consuming and labor-intensive. Therefore, a transfer vehicle for high-voltage switchgear circuit breakers needs to be designed to solve these problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a transfer cart for high-voltage switchgear circuit breakers, which solves the problem mentioned in the background art that existing handcart circuit breaker transfer carts on the market cannot automatically pull out or send the circuit breaker handcart into the switchgear, resulting in time-consuming and labor-intensive operation.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A transfer cart for a high-voltage switchgear circuit breaker includes a cart body with casters at the bottom, a transfer seat mounted on the top of the cart body via a lifting mechanism, a drive mechanism for moving the cart on the top of the transfer seat, the drive mechanism including drive motors on both sides of the transfer seat, a screw at the output end of the drive motor, the screw being rotatably connected to the transfer seat, a fixing block threaded onto the screw, and a pneumatic gripper for gripping the cart handle on the fixing block.

[0007] As a further improvement to this utility model, the top of the two sets of fixing blocks is fixed with a vertical rod, the two sets of vertical rods are fixedly connected by a limiting rod, and a buffer block is provided on the side of the limiting rod near the handcart.

[0008] As a further improvement to this utility model, a limiting plate is provided on the transfer seat away from the outside of the transfer vehicle.

[0009] As a further improvement to this utility model, a trolley handle is fixed on the side of the vehicle body near the positioning rod, and two sets of positioning rods are provided on the transfer seat on the side away from the trolley handle.

[0010] As a further improvement to this utility model, the lifting mechanism includes a cross arm and a cylinder. The cross arm is installed between the transfer seat and the vehicle body. One end of the cross arm is hinged to the transfer seat and the vehicle body, and the other end is slidably connected to the transfer seat and the vehicle body. The movable end of the cross arm is connected to a cylinder, and the cylinder is fixed to the top of the vehicle body.

[0011] As a further improvement to this utility model, the bottom end of the transfer seat is provided with a locking mechanism. The locking mechanism includes a connecting piece fixedly connected to the transfer seat. An adjusting rod is rotatably connected to the connecting piece. A right-angle hook is provided on the side of the adjusting rod near the positioning rod, and an adjusting handle is provided on the side of the adjusting rod near the trolley handle.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This utility model uses a drive mechanism on a transfer seat to enable pneumatic grippers to clamp the handle of the handcart. Then, a drive motor drives a fixed block, which in turn drives the pneumatic grippers, which in turn move the handcart on the transfer seat, thus achieving automatic handling of the handcart and saving workers' effort and time.

[0014] This invention, by setting a lifting mechanism between the transfer seat and the vehicle body, enables the transfer seat to rise or fall stably, and is more time-saving and labor-saving than the original lifting method of adjusting four manual screw wheels. Attached Figure Description
