Description

Technical Field

[0001] The present invention belongs to the technical field of GIS cylindrical device assembly, and particularly relates to an auxiliary installation vehicle for GIS cylindrical devices. Background Art

[0002] A three-position switch is a switch device that integrates the functions of a disconnector and an earthing switch, and is mainly used in GIS to control the on / off of the GIS circuit.

[0003] Chinese Patent Application Publication No. CN105761964A discloses a three-position disconnector (i.e., a GIS cylindrical device). The three-position disconnector includes a cylinder body. A moving contact, an isolating contact and an earthing contact are arranged inside the cylinder body. The cylinder body has an upper opening, a lower opening, a left opening and a right opening. Pot-type insulators are arranged on both the upper opening and the lower opening. The upper opening, the lower opening and the right opening are used for docking with corresponding devices in GIS, and the left opening is used for installing an operating mechanism.

[0004] Since the openings on the cylinder body are in different directions, and the volume and weight of the three-position switch are relatively large, when assembling the three-position switch at present, a large device such as a crane is needed to hoist the cylinder body, and it is necessary to manually turn the cylinder body back and forth to install the corresponding contacts and components at the corresponding openings, and the operation is rather troublesome. In addition, in addition to the vertical docking and horizontal docking working conditions between the existing GIS cylindrical devices, there is also an inclined docking working condition, and it is necessary to manually adjust the height and angle of the three-position switch to align the cylindrical devices, and the operation is troublesome and the installation efficiency is low. Summary of the Invention

[0005] The purpose of the present invention is to provide an auxiliary installation vehicle for GIS cylindrical devices to solve the technical problems of troublesome installation operation and low installation efficiency of cylindrical devices in the prior art.

[0006] To achieve the above purpose, the technical solution of the auxiliary installation vehicle for GIS cylindrical devices provided by the present invention is: The auxiliary installation vehicle for GIS cylindrical devices includes a vehicle body and a support frame. An elevating drive device for driving the support frame to lift is arranged between the vehicle body and the support frame. A swing frame is rotatably assembled on the support frame. The swing frame is used for connecting with one of the openings of the cylindrical device. A swing drive device with a self-locking function is also arranged on the support frame. The swing drive device is used for driving the swing frame to swing. A traveling device is arranged at the bottom of the vehicle body.

[0007] The beneficial effect is that the GIS cylindrical device auxiliary installation vehicle provided by the present invention can install the cylindrical device on the swing frame through the flange at one of the openings, compared with the manual auxiliary crane in the prior art to assemble and install the cylindrical device. The swing drive device drives the swing frame to swing, so that the cylindrical device installed on the swing frame swings with the swing frame to adjust the angles of the other two openings of the cylindrical device, and locks the swing frame at an adapted angle so that the operator can install the contact components in the cylindrical device into the corresponding openings on the cylindrical body, which is easy to operate; and the lifting drive device can adjust the height of the cylindrical device so that the height of the opening on the cylindrical device can be adapted to the corresponding cylindrical device in the GIS, saving time and effort and improving installation efficiency. In addition, after the angle and height of the cylindrical device are adjusted, the walking device on the vehicle body facilitates the movement of the cylindrical device auxiliary installation vehicle so that the cylindrical device and the adapted cylindrical device are fixedly connected.

[0008] As a further improvement, the swing frame is assembled on the support frame through a rotating shaft, and the swing drive device includes a driving member, a worm wheel and a worm, the worm wheel is arranged on the rotating shaft, the worm is connected to the driving member, and the worm wheel and the worm constitute a worm gear reducer.

[0009] The beneficial effects are: the worm gear reducer has a simple structure and is easy to install.

[0010] As a further improvement, the driving member is an operating handle.

[0011] The beneficial effect is that the worm is rotated by manually rotating the operating handle, and the specific angle of the cylindrical device can be manually observed in real time, which is relatively accurate.

[0012] As a further improvement, the swing frame is assembled on the support frame through a rotating shaft. The swing drive device includes a driving wheel, a driven wheel and a drive motor. The driving wheel is connected to the driven wheel through transmission. The driven wheel is set on the rotating shaft, and the driving wheel is set at the driving end of the drive motor.

[0013] The beneficial effect is that when the driving end of the driving motor is directly connected to the rotating shaft, the torque transmission is a constant value, and the transmission coordination between the driving wheel and the driven wheel can increase the torque and reduce the driving motor power by adjusting the number of teeth on the wheel.

[0014] As a further improvement, the support frame includes two vertical frames arranged at an interval, and the swing frame is arranged on the two vertical frames.

[0015] The beneficial effect is that the two upright frames can provide better support for the swing frame, and the space between the two upright frames can also provide swing space for the three-position switch.

[0016] As a further improvement, the swing frame includes two L-shaped plates arranged at intervals, and the two L-shaped plates are respectively arranged on the two vertical frames.

[0017] The beneficial effects are as follows: The L-shaped plate has a simple structure and is convenient to manufacture.

[0018] As a further improvement, a reinforcing rib plate is provided on the inner side of the L-shaped plate.

[0019] The beneficial effects are as follows: The reinforcing rib plate can increase the structural strength of the swing frame.

[0020] As a further improvement, fixing holes for fixedly connecting with the flange of the cylindrical device are provided on the swing frame.

[0021] The beneficial effects are as follows: With such a design, it is convenient to fix the cylindrical device on the swing frame.
