[0022] The utility model will be further described below in conjunction with the accompanying drawings.

[0023] like Figure 1 and Figure 2 As shown, a positive feeder maintenance auxiliary tool of an embodiment of the utility model includes a U-shaped bracket 1, a fixing rod 2, a support rod 3 and a hanging rope 4. The fixing rod 2 is detachably arranged on the opening side of the U-shaped bracket 1, and the support rod 3 is fixed to the other side of the U-shaped bracket 1. Hanging ropes 4 are provided at both ends of the support rod 3, and the end of the hanging rope 4 away from the fixing rod 2 can be connected to the horizontal shoulder frame 100 of the positive feeder.

[0024] The positive feeder maintenance auxiliary tool of this embodiment has a simple overall structure, is easy for maintenance personnel to carry on the pole, and has a simple installation method. Figure 1 As shown, the positive feeder maintenance auxiliary tool of the utility model can be hung on the horizontal shoulder frame 100 of the positive feeder through the hanging rope 4 located in the middle to achieve initial positioning, and then the U-shaped bracket 1 surrounds the contact network support rod 200 and installs the fixing rod 2, and then the hanging rope 4 located at the end is hung on the horizontal shoulder frame 100 of the positive feeder to complete the installation. The support rod 3 can be used for maintenance personnel to stand or sit, which greatly reduces the labor intensity and improves the safety of maintenance work, making the replacement of the insulator 300 much easier. Since the hanging ropes 4 are provided at both ends of the support rod 3, the stability of the support rod 3 is good. After the maintenance is completed, it is only necessary to remove the hanging rope 4 and disassemble the fixing rod 2 to separate the positive feeder maintenance auxiliary tool, which is convenient to use.

[0025] like Figure 2 and Figure 3 As shown, the U-shaped bracket 1 includes a crossbar 11 and two longitudinal bars 12, the two ends of the crossbar 11 are respectively connected to one end of a longitudinal bar 12, and the fixed rod 2 is a double-headed screw, and the two ends of the fixed rod 2 pass through a longitudinal bar 12 and are fixed to the U-shaped bracket 1 with nuts 5. After the fixed rod 2 is installed on the U-shaped bracket 1, the contact network support rod 200 is inside the U-shaped bracket 1, but the U-shaped bracket 1 can still move slightly, and it is not necessary to firmly fix the U-shaped bracket 1 and the contact network support rod 200, but to use the hanging rope 4 to ensure that the support rod 3 has a stable state, so that the installation and disassembly work are easier to carry out. When installing the fixed rod 2, the nuts 5 at both ends of the fixed rod 2 do not need to be tightened, and the nuts 5 can be screwed by hand to ensure that they will not loosen from the fixed rod 2. Through the limiting effect of the U-shaped bracket 1 and the fixed rod 2, the support rod 3 will not have obvious pitching and rolling, so that the maintenance personnel can stand or sit on the support rod 3 stably.

[0026] like Figure 2 As shown, one end of the support rod 3 passes through the cross bar 11 and is perpendicular to the cross bar 11. The support rod 3 passes through the cross bar 11 instead of being connected only to the surface of the cross bar 11, so that the support rod 3 and the U-shaped bracket 1 can be firmly connected to ensure a higher structural strength.

[0027] Furthermore, the positive feeder maintenance auxiliary tool also includes a reinforcing rod 6, both ends of which are respectively connected to a longitudinal rod 12, and the support rod 3 passes through the reinforcing rod 6. By providing the reinforcing rod 6, on the one hand, the structural strength of the U-shaped bracket can be improved, and on the other hand, an additional fixing position is provided for the support rod 3, so that the support rod 3 can be fixed more firmly.

[0028] Furthermore, the reinforcing rod 6 is parallel to the cross bar 11 and is spaced apart so that the hanging rope 4 can pass through the gap between the reinforcing rod 6 and the cross bar 11, which facilitates connecting the hanging rope 4 to the supporting rod 3. Figure 2 As shown, one end of the support rod 3 away from the cross bar 11 is provided with a connection hole 31 for connecting the hanging rope 4. Since the end of the support rod 3 away from the cross bar 11 lacks a structure that can effectively fix the hanging rope 4, the connection hole 31 is provided on the support rod 3 to prevent the hanging rope 4 from loosening.

[0029] like Figure 2 As shown, the positive feeder maintenance auxiliary tool also includes an auxiliary connecting rod 7 arranged on one side of the reinforcing rod 6, and the support rod 3 passes through the reinforcing rod 6 and is connected to the auxiliary connecting rod 7. When replacing the insulator 300, the maintenance personnel will stand at the end of the support rod 3 away from the cross bar 11, so that the end of the support rod 3 connected to the cross bar 11 is subjected to a larger force. By providing the auxiliary connecting rod 7, the support rod 3 can be fixed more firmly, thereby improving the reliability of the structure.

[0030] like Figure 1 As shown, a safety buckle 8 is provided at one end of the lanyard 4 away from the fixing rod 2. The safety buckle 8 can be conveniently hung on the horizontal shoulder frame 100 and removed from the horizontal shoulder frame 100, thereby improving the installation and removal efficiency of the lanyard 4 and facilitating use.

[0031] In this embodiment, the U-shaped bracket 1 and the support rod 3 are both made of aluminum alloy, so that the positive feeder maintenance auxiliary tool has high structural strength and light weight, which is convenient for maintenance personnel to carry to the working position and reduces labor intensity. At the same time, the positive feeder maintenance auxiliary tool is not easy to rust, easy to maintain and has a long service life.

[0032] The crossbar 11, the longitudinal bar 12 and the support bar 3 in the U-shaped bracket 1 are all made of square tubular aluminum alloy, and the support bar 3 has a flat surface for maintenance personnel to stand on. In order to avoid scratching personnel by the edges, the edges of the crossbar 11, the longitudinal bar 12 and the support bar 3 are all rounded.

[0033] In this embodiment, the length of the hanging rope 4 is greater than 1.5 meters and less than 1.8 meters. Setting the length of the hanging rope 4 in this range can adapt to the height of most maintenance personnel, so that the maintenance personnel can perform maintenance work in a more comfortable posture, reducing the difficulty of maintenance. In this embodiment, the hanging rope 4 is a stainless steel rope.

[0034] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
