Description

Bo-shaped cat ladder

Technical Field

The application relates to the technical field of auxiliary equipment for power system detection, in particular to a Chinese character 'Bo' type cat ladder.

Background

In the process of electric power operation of a power grid, when electric power equipment is required to be arranged at positions close to a wall or table lookup operation is required to be performed, if the equipment is placed at a high position, operators are often required to use equipment such as a ladder to assist in installation or detection.

The traditional cat ladder is generally an I-shaped ladder, when the ladder is used, the higher end of the ladder needs to be manually propped against a wall or a vertical face, and the other end of the ladder is propped against the ground side, so that the ladder, the ground and the vertical face form a triangle.

However, the conventional ladder lacks fixing measures with the vertical surface and the ground, so that the stability is poor, and when the placement angle of the ladder is increased, the stability is reduced more obviously. When operating personnel work on the cat ladder, the safety is poor and the operation personnel can only keep stable by leaning on the cat ladder.

The adjusting part 12 at the lower part is designed to be telescopic, so that the height of the fixing part 11 away from the ground is adjusted to be suitable for operations at different heights.

A climbing ladder 2; one end of the climbing ladder 2 is hinged with the bearing ladder 1, and the hinged position is arranged at the joint of the fixed part 11 and the adjusting part 12; in this embodiment, the climbing ladder 2 is used for an operator to climb up and down, and the fixed angle between the climbing ladder 2 and the carrying ladder 1 needs to be adjusted adaptively in consideration of different situations such as the height of the field operation and the size of the field.

The bearing ladder 1 is connected with the climbing ladder 2 to form a shape of a Chinese character 'Bu', as shown in figure 1, when the bearing ladder 1 and the climbing ladder 2 form the shape of the Chinese character 'Bu', the bearing ladder 1 is vertically arranged and is abutted against a wall or a vertical surface, the climbing ladder 2 and the bearing ladder 1 are obliquely arranged at a certain angle, at the moment, when an operator climbs on the climbing ladder 2, the force born by the ladder is conducted to the bearing ladder 1, and a triangular stable structure is formed between the climbing ladder 2 and the bearing ladder 1 as well as between the climbing ladder and the ground, so that the climbing ladder structure provided by the application has higher stability compared with the traditional I-shaped climbing ladder.

Further, in some other embodiments, the adjusting part 12 may be formed of a plurality of first sub-ladder units 100 connected in sequence; the adjusting part 12 is formed by adopting a plurality of sub-ladder units, the number of the first sub-ladder units can be correspondingly designed according to actual height requirements, and then the adjusting part is formed by using different numbers of the first sub-ladder units according to different heights, so that the device is more flexible.

In order to ensure effective fixation and change of the positional relationship between two adjacent sub-ladder units, in some embodiments, a buckle assembly 3 is disposed between any two adjacent sub-ladder units 100, in this embodiment, the buckle assembly 3 has two working states, namely an open state and a closed state, when the buckle assembly 3 is in the open state, the two adjacent sub-ladder units 100 corresponding to the buckle assembly 3 are slidably connected, at this time, several first sub-ladder units can be folded into a structure with smaller space, so as to adjust the overall length of the ladder, and when all the first sub-ladder units are folded, the overall transfer of the device is facilitated; when the buckle assembly 3 is in a closed state, two adjacent first sub-ladder units 100 corresponding to the buckle assembly 3 are fixedly connected, at this time, the fixed relation between the two first sub-ladder units 100 cannot be changed temporarily, and the stability of the fixed structure is ensured.

The second sub-ladder unit 200 and the first sub-ladder unit 100 may have the same structure, and the two concepts are adopted to explain the case where the two sub-ladder units have different lengths and different numbers, that is, the number and the length of the sub-ladder units constituting the power ladder 1 and the climbing ladder 2 may be different, for example, the power ladder 1 is formed of four first sub-ladder units 100, the climbing ladder 2 is formed of six second sub-ladder units 200, and the like. In particular, it can be explained from fig. 2 and 3:

referring to fig. 2, which is a schematic diagram illustrating an angle relationship between a lower bearing ladder and a climbing ladder according to an embodiment, when an angle between the bearing ladder 1 and the climbing ladder 2 is smaller in a use process of the climbing ladder of the present application, the bearing ladder 1 may be formed by fixedly connecting four first sub-ladder units 100, and the corresponding climbing ladder 2 is also formed by fixedly connecting four second sub-ladder units 200; referring to fig. 3, an angular relationship between the lower bearing ladder and the climbing ladder according to another embodiment is shown, when the angles of the bearing ladder 1 and the climbing ladder 2 are adjusted to be relatively small, for example, the number of the second sub-ladder units 200 forming the climbing ladder 2 is kept unchanged, and at this time, the number of the first sub-ladder units 100 forming the bearing ladder 1 needs to be reduced from four to three, and any two adjacent first sub-ladder units 100 need to be changed from a fixedly connected relationship to a furled relationship.

Further, in order to achieve a switching of states between two adjacent first sub-ladder units 100 or two second sub-ladder units 200, as shown in fig. 4 and 5, in some possible embodiments, the buckle assembly 3 comprises:

A first connecting rod 31;
