Problems solved by technology

However, with the use of auxiliary tools for climbing ladders of steel pipe towers, it is gradually found that there are several defects in them: (1) The volume and weight are large, which is not convenient for transportation, handling and storage; (2) Most of them cannot be adjusted according to the distance from the ground Flexible adjustment, poor versatility; (3) Most of them cannot achieve a stable connection with the climbing ladder, and the fixation is unstable and easy to slide, posing safety hazards

Embodiment 1

[0046] like Figure 1 to Figure 3 As shown, the present embodiment provides a steel pipe tower ladder climbing auxiliary device, including a ladder bar 1, anti-skid spikes 2 and a lifting base 3; Threaded holes 101, wherein the top of one ladder rod 1 is provided with a fastening part 102 for realizing connection with the bottom of the ladder 4, and the tops of the other ladder rods 1 are provided with first screw rods 103 compatible with the first threaded hole 101 , the ladder rods are connected to each other through the first screw rod 103 and the first threaded hole 101.

[0047] In this embodiment, the ladder bar 1 can be artificially divided into two types according to the structure of the above ladder bar 1 . like figure 2 As shown, a clamping support rod with a clamping part 102 on the top is provided, and one is connected to the uppermost end of the device during use to realize the clamping connection with the steel pipe tower ladder 4; image 3 Shown, another kin...

Embodiment 2

[0060] like Figure 7 As shown, the structure of this embodiment is the same as that of Embodiment 1, the difference is that the clamping part 102 includes two correspondingly arranged limiting rods 1024, both of which are L-shaped, and one end is fixedly welded to the ladder bar 1 Above, the welding point is set lower than the top of the ladder bar 1, and the top of the welded stop bar 1024 is set higher than the top of the ladder bar 1. When in use, the foot nail at the bottom of the ladder 4 is stuck between the stop bar 1024 and the ladder bar 1 The clamping part 102 is provided in the limiting gap, which is simple in structure, convenient in manufacture and strong in practicability.

Abstract

The invention belongs to the technical field of electric power facilities, and provides a steel tube tower ladder stand auxiliary device. The steel tube tower ladder stand auxiliary device comprises aplurality of ladder rods, a plurality of anti-skidding foot pins and a lifting base. First threaded holes are formed in the bottom ends of the ladder rods, wherein a clamping and fixing portion usedfor being connected with the bottom of the ladder stand is arranged at the top end of one of the ladder rods, first threaded rods adaptive to the first threaded holes are arranged at the top ends of the other ladder rods, and the ladder rods are connected with each other through the first threaded rods and the first threaded holes. The anti-skidding foot pins are detachably mounted on the ladder rods. The lifting base is provided with a second threaded rod adaptive to the first threaded holes, and the lifting base is connected with the ladder rods through the second threaded rod and the firstthreaded holes. According to the steel tube tower ladder stand auxiliary device, flexible adjustment of the height can be conveniently carried out according to the distance from the ladder stand to the ground, the volume is small, and transporting, carrying and storing are convenient.

Description

technical field [0001] The invention relates to the technical field of electric power facilities, in particular to a steel pipe tower ladder climbing auxiliary device and an installation method thereof. Background technique [0002] The steel pipe tower is a support structure for overhead transmission lines to support conductors and lightning protection lines, so that the conductors meet the distance limit requirements to the ground and ground objects, and can bear the loads of conductors, lightning protection lines and their own loads and external loads. At present, the steel pipe tower includes the tower body and the climbing ladder installed on the tower body. During construction, in order to prevent non-staff members from climbing the steel pipe tower without authorization, a certain safety distance is set at the bottom of the ladder from the ground. This measure can effectively prevent non-staff workers from climbing the steel pipe tower. The dangerous behavior of climb...
