Embodiment 1

[0045] Such as Figure 1 to Figure 3 As shown, a manned trolley for 500kV tension insulator strings includes a horizontal plate 1, two vertical plates 11 are symmetrically arranged on the lower end surface of the horizontal plate 1, and two vertical plates 11 are symmetrically arranged on the outer sides of the two vertical plates 11. A belt transmission mechanism 2, the belt transmission mechanism 2 includes a belt 21, and a first driving wheel 22 and a second driving wheel 23 for supporting the belt 21, and two symmetrical first driving wheels 22 are connected by a first rotating shaft 313 , the two symmetrical second driving wheels 23 are connected through the second rotating shaft 314, the first rotating shaft 313 and the second rotating shaft 314 are both set on the two vertical plates 11, and also include a transmission mechanism 3, and the transmission mechanism 3 includes a set In the second transmission shaft 36 below the horizontal plate 1, the second transmission sh...

Embodiment 2

[0047] Such as Figure 1 to Figure 4 As shown, the present embodiment is based on Embodiment 1, the upper end surface of the horizontal plate 1 is vertically provided with a fixed frame 12, and the first transmission shaft 32 is arranged on the fixed frame 12; the horizontal plate 1, the fixed frame 12 and The vertical plate 11 is made of epoxy resin; the belt transmission mechanism 2 also includes a plurality of driven wheels 24, and the driven wheels 24 support the belt 21 together with the first driving wheel 22 and the second driving wheel 23; the belt 21 The outer surface of the horizontal plate 1 is provided with rubber lines; the two ends of the horizontal plate 1 are vertically provided with baffles 4; the baffle 4 is detachably arranged on the horizontal plate 1; the two vertical ends of the baffle 4 are The inner bending forms an arc surface; the lower end of the baffle plate 4 is provided with a safety rope 5; the height of the bottom of the vertical plate 11 is hig...

specific Embodiment approach

[0049] The equipotential operator places the trolley on the insulator string at the cross arm, and fastens the safety rope 5; then the personnel sits on the horizontal plate 1, and puts on the safety belt for the human body; turns the steering wheel 31 clockwise, and Under the action of the transmission mechanism 3, the belt 21 rotates clockwise, the trolley moves forward, and the human body gradually enters a strong electric field. When the human body emits a strong electric field, just turn the steering wheel 31 counterclockwise.

Abstract

The invention discloses a manned trolley for a 500kV strain insulator string. The manned trolley comprises a horizontal plate, wherein two vertical plates are symmetrically arranged at the lower end of the horizontal plate; two belt conveying mechanisms are symmetrically arranged on the outer side of the two vertical plates; each belt conveying mechanism comprises a belt, and a first driving wheel and a second driving wheel used for driving the belt, and also comprises a transmission mechanism; and the transmission mechanism is used for controlling the movement of the corresponding belt conveying mechanism. According to the manned trolley provided by the invention, a steering wheel is operated by an operator to drive the transmission of the transmission mechanisms so as to enable the trolley to move forwards, stop and move backwards; and in addition, the trolley is convenient to operate, and is applicable to a high-voltage electrified operation without requiring the operator to climb to replace an insulator, thereby lowering the requirement on the operator.

Description

technical field [0001] The invention relates to the technical field of auxiliary tools for replacing insulator strings, in particular to a trolley for carrying people on 500kV tension insulator strings. Background technique [0002] In the live work of the transmission line, the live workers enter the strong electric field to work according to the task, that is, the human body is in contact with the charged body to form an equipotential body. At present, the methods of entering the strong electric field mainly include the insulating soft ladder method, the insulating flat ladder method, the insulating hard ladder method, the hanging basket method and the method of entering along the insulator string. The insulating ladder method is to hang the ladder head on the wire or the ground wire, and the operator climbs to the working point along the ladder. The insulating flat ladder method is mainly used for live work on 110kV and 220kV transmission lines. The ladder head is hung o...
