Abstract
Description
Technical Field
[0001] The utility model belongs to the field of electrical engineering, and particularly relates to the work at height in power production. Background Art
[0002] The power system is extremely important to today's society. People's work and life are inseparable from electricity. After the power system operates for a certain period of time, failures are inevitable. As an important part of the power system, utility poles need to be frequently pre-inspected and repaired. The ladders currently in use are generally aluminum alloy ladders, and only anti-slip sleeves are added at the bottom of the ladders. For relatively smooth or uneven ground, the ladders will slip or be unstable, reducing the usage scenarios and safety of the anti-slip ladders. Summary of the Utility Model
[0003] The purpose of the utility model is to provide an anti-slip ladder with a support and anti-slip function at the bottom, which can be applicable to smooth or uneven ground, increase the stability and safety of the anti-slip ladder, ensure the safety and health of maintenance personnel, and facilitate the construction of maintenance personnel.
[0004] The technical solution of the utility model is as follows:
[0005] An anti-slip ladder with a support and anti-slip function at the bottom includes two vertical rods and a plurality of first crossbars arranged between the two vertical rods. A first anti-slip sleeve is provided at the bottom of each vertical rod. A second crossbar is provided near the bottom of the anti-slip ladder. The second crossbar is a cylinder and has a through hole inside. The anti-slip ladder further includes an anti-slip support rod rotatably connected to the second crossbar. The rotating sleeve at the top of the anti-slip support rod is rotatably matched with the through hole of the second crossbar. A second anti-slip sleeve is provided at the bottom of the anti-slip support rod.
[0006] The anti-slip support rod further includes an adjusting rod, a first fixing nut, a second fixing nut and a sleeve. The adjusting rod passes through the sleeve and is slidably matched with it. The first fixing nut is matched with the threaded through hole on the second crossbar to fix the rotating shaft to the second crossbar and limit its relative rotation. The second fixing nut is matched with the threaded hole on the sleeve to fix the position of the adjusting rod in the sleeve and limit its up and down telescoping. This design enables the support anti-slip rod to have sufficient contact with the ground. Tighten the first nut and the second nut to make the support anti-slip rod and the ladder itself firmly integrated.
[0007] The adjusting rod is connected to the rotating sleeve by a clamping sleeve, which enables the anti-slip support rod to be adjusted at different angles, making the anti-slip support rod applicable to ground with different heights;
[0008] The adjusting rod is connected to the second anti-slip sleeve through a rubber ring, which increases the friction between the anti-slip ladder and the ground and improves the stability of the anti-slip ladder.
[0009] Compared with the prior art, the beneficial effects of the utility model include:
[0010] 1) The utility model provides an anti-slip ladder with a support and anti-slip function at the bottom. By providing anti-slip support rods with adjustable angles and lengths, the anti-slip support rods and the ladder are fixed by two fixing nuts, and rubber rings are provided to increase the friction between the anti-slip ladder and the ground, thereby increasing the stability of the anti-slip ladder.
[0011] 2) The utility model provides anti-slip support rods with adjustable angles and lengths, so that the anti-slip ladder is applicable to uneven ground;
[0012] 3) The anti-slip support rods and the ladder itself are firmly integrated by fixing with two fixing nuts. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] As Figure 1 shown, two vertical rods 1 and a plurality of first cross bars 2 arranged between the two vertical rods are provided. A first anti-slip sleeve 4 is provided at the bottom of each vertical rod 1. A second cross bar 2' is provided near the bottom of the anti-slip ladder. The second cross bar 2' is a cylinder and has a through hole inside. The anti-slip ladder further includes an anti-slip support rod 3 rotatably connected to the second cross bar 2'. The rotating sleeve 7 at the top of the anti-slip support rod 3 is rotationally matched with the through hole of the second cross bar 2'; a second anti-slip sleeve 9 is provided at the bottom of the anti-slip support rod 3.
[0018] As Figure 2 shown, 2 anti-slip support rods are provided; the anti-slip support rod 3 further includes an adjusting rod 5, a first fixing nut 6, a second fixing nut 8 and a sleeve 10; the adjusting rod 5 is inserted into the sleeve 10 and is slidably matched therewith; the second fixing nut 8 is matched with the threaded through hole on the second cross bar 2' for fixing the rotating sleeve 7 to the second cross bar 2' to limit its relative rotation; the second fixing nut 8 is matched with the threaded hole on the sleeve 10 for fixing the position of the adjusting rod 5 in the sleeve 10 to limit its up and down telescoping. This design enables the support anti-slip rod to have sufficient contact with the ground. By tightening the first nut and the second nut, the support anti-slip rod and the ladder itself are firmly integrated.
[0019] The adjusting rod 5 is connected to the rotating sleeve 7 in a clamping manner. This design enables the anti-slip support rod to be adjusted at different angles, making the anti-slip support rod suitable for floors with different heights.
[0020] The adjusting rod 5 is connected to the second anti-slip sleeve 9 through a rubber ring. This design increases the friction between the anti-slip ladder and the ground and enhances the stability of the anti-slip ladder.
[0021] Working principle: Hold the vertical rod 1 with both hands and lean it against the working point for elevated work. Expand the anti-slip support rods 3 on both sides. Adjust the lengths of the two anti-slip support rods 3 through the telescopic rod 5. Rotate the rotating sleeves 7 of the two anti-slip support rods 3 respectively to adjust the angles of the anti-slip support rods 3 so that the anti-slip support rods 3 have sufficient contact with the ground. Tighten the first fixing nut 6 of the telescopic rod and the second fixing nut 8 of the rotating sleeve to ensure the stability of the anti-slip support rods and the anti-slip ladder. When storing, loosen the first fixing nut 6 and the second fixing nut 8 and retract the anti-slip support rods 3.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art in the said technical field, various changes can be made without departing from the gist of the present utility model.
