Problems solved by technology

[0002] Electric power towers are usually relatively high. For iron towers installed in substations and other places, when maintaining power equipment, workers climb along the height direction of the tower through ladders and other equipment. Since the tower body is usually formed by overlapping steel structures, the staff cannot It is convenient to rest. The iron tower set up in the field and the stepped ladder are easy for non-staff to climb, which poses a safety hazard. Therefore, the staff can only climb slowly along the tower body, which is very laborious, and there is no rest platform in the middle

Embodiment 1

[0022] like figure 1 As shown, a power transmission tower includes a tower body 101 and a first rotating shaft 102-1 arranged on one end surface of the tower body 101. The tower body can be formed by overlapping structures such as angle steel, and the second rotating shaft 102-1 2 and the first rotating shaft 102-1 are arranged in parallel at equal intervals along the height direction of the tower body 101, and a bracket 103 is provided on the end face of the side opposite to the first rotating shaft 102-1, so that the bracket can be connected to the first The rotating shafts are arranged at equal heights and at equal intervals. A support plate 104 is provided on the first rotating shaft 102-1, and a support structure is provided on the lower end surface of the supporting plate. One end of the supporting plate 104 is rotatably connected to the first rotating shaft 102. -1, the supporting structure is fitted on the first rotating shaft, and when the support plate is relatively ...

Embodiment 2

[0025] like Figure 4 As shown, in this embodiment, in order to improve the stability of the support plate, preferably, a flange 111 corresponding to the slot 105 is provided on the upper end surface of the bracket 103 . The flange is relatively rotatably connected to the bracket, an annular groove is set on the bracket, and a sleeve 120 is placed in the annular groove, so that the flange has a U-shaped structure, and one end of the flange is fixedly connected to the sleeve, and the flange The two ends are free ends, and when the supporting plate fits on the upper end surface of the bracket, the casing tube is rotated relative to the bracket, so that the free ends of the flange are inserted into the inside of the slot.

[0026] In order to prevent non-workers from climbing the tower body through one side of the bracket, in this embodiment, it is further preferred that a barb 112 inclined to the outside of the tower body 101 is provided on the lower edge of the bracket 103 .

Embodiment 3

[0028] like Figure 4 , 5 As shown, in this embodiment, on the basis of Embodiment 1 or 2, in order to facilitate the operation of the support plate, preferably, a counterbore is provided on the side wall of the tower body 101, so that the counterbore is located outside the tower body, The counterbore is located near the end of the first rotating shaft, and a pressing rod 113 is arranged inside the counterbore, the axis of the pressing rod is parallel to the axis of the first rotating shaft, and a through hole is arranged inside the counterbore, so The pressure rod 113 runs through the through hole and stretches out of the through hole. A baffle plate 114 is arranged at the end of the pressure rod 113. The baffle plate is located outside the tower body. The outer diameter of the baffle plate is larger than The inner diameter of the hole, the return spring 115 is set on the pressure rod 113, one end of the return spring 115 is fixedly connected to the baffle plate 114, and the...

Abstract

The invention discloses an electric power transmission tower which comprises a tower body and rotating shafts arranged on the end face of one side of the tower body. The rotating shafts are parallelly arranged at equal intervals in the height direction of the tower body, a support is arranged on the end face of one side opposite to each rotating shaft, the rotating shaft is provided with a supporting plate, one end of the supporting plate is rotatably connected to the rotating shaft, the end face of one side of the supporting plate far away from the rotating shaft is provided with a clamping groove, the lower end face of the rotating shaft is provided with a cross rod, the cross rod is provided with grooves formed at intervals, torsional springs are arranged on the inner sides of the grooves and sleeved with locating pins, and when the supporting plate located on the lower portion rotates relative to the rotating shaft, the locating pin located on the rotating shaft on the upper portion can be clamped on the inner side of the clamping groove. A platform for workers to stand or rest is formed in case of need through the supporting plate, so that the workers overhaul a device or rest conveniently.

Description

technical field [0001] The invention relates to an electric power transmission tower. Background technique [0002] Electric power towers are usually relatively high. For iron towers installed in substations and other places, when maintaining power equipment, workers climb along the height direction of the tower through ladders and other equipment. Since the tower body is usually formed by overlapping steel structures, the staff cannot It is convenient to rest. The iron tower set up in the field and the stepped ladder are easy to be climbed by non-staff, which poses a safety hazard. Therefore, the staff can only climb slowly along the tower body, which is very laborious, and there is no rest platform in the middle. Contents of the invention [0003] The purpose of the present invention is to provide a power transmission tower, by adopting relatively rotatable support plates, the support plates can form a platform for workers to stand or rest when needed, which is convenien...
