[0035] Implementation Method 1

[0036] Reference Figures 1 to 4The present embodiment is an optional embodiment of the present application, which discloses a work ladder for outdoor power engineering construction, including a first support rod 1 and a second support rod 2, wherein one end of the first support rod 1 is hingedly connected to one end of the second support rod 2 by a pin shaft, and a limited seat 11 is further provided at one end where the first support rod 1 and the second support rod 2 are hinged, and a limited slot 12 is provided on the limited seat 11, and the cross section of the limited slot 12 is a U-shaped structure, and the limited slot 12 is adapted to the second support rod 2, and a limited module is also provided on the limited seat 11, and the limited module includes a limited screw 13, and the limited screw 13 and the limited screw 13 are connected to the limited screw 13. One side of the open end of the limiting groove 12 is hingedly connected, and the other side of the limiting groove 12 is provided with a second limiting groove 14, and the limiting screw 13 is inserted into the second limiting groove 14, and a limiting nut 15 is also provided on the limiting screw 13. The setting of the limiting screw 13 and the limiting seat 11 can effectively improve the connection strength between the second support rod 2 and the first support rod after unfolding, thereby ensuring the safety of use; it should also be pointed out that the open end of the limiting groove 12 is located at the back of the work ladder, so that the rotation of the second support rod 2 is further limited by the limiting seat 11, thereby ensuring the connection stability between the first support rod 1 and the second support rod 2;

[0037] A plurality of cross bars 3 are disposed on each of the first support rod 1 and the second support rod 2. Along the axis direction of the first support rod 1 and the second support rod 2, each of the cross bars 3 is disposed on both sides of the first support rod 1 and the second support rod 2, and each of the cross bars 3 is hingedly connected to the first support rod 1 or the second support rod 2;

[0038] It should be noted that the cross bars 3 on both sides can be staggered or symmetrically arranged, depending on the actual situation;

[0039] A limiting rod 4 is arranged at the lower side of each of the cross bars 3, and each of the limiting rods 4 is connected to the first support rod 1 or the second support rod 2 respectively. At the same time, a first limiting groove 7 is arranged on the top surface of the limiting rod 4, and the cross-sectional shape of the first limiting groove 7 is the same as the cross-sectional shape of the limiting rod 4 to ensure that the first limiting groove 7 can be stably engaged with the limiting rod 4; a limiting spring piece 8 is also arranged at the entrance end of the first limiting groove 7;

[0040] The bottom surface of the limiting rod 4 is also provided with a reinforcing rib 9, and the reinforcing rib 9 abuts against the first support rod 1 or the second support rod 2; at the same time, a fixing screw 10 is threadedly connected to the limiting rod 4, and the fixing screw 10 is inserted into the first limiting groove 7 and abuts against the side surface of the cross bar 3;

[0041] The above measures can ensure the connection stability between the cross bar 3 and the limit rod 4; at the same time, since the limit rod 4 is located at the lower side of the cross bar 3, and the limit rod 4 is fixedly connected to the first support rod 1 or the second support rod 2, when the staff steps on the cross bar 3, the limit rod 4 will be able to provide stable support for the cross bar 3, which not only ensures the safety of the work ladder, but also has a simple structure.

[0042] A fixing piece 16 is hinged on each of the cross bars 3, and a fixing rod 17 is provided on the first support rod 1 or the second support rod 2. A U-shaped groove 18 adapted to the fixing rod 17 is provided on the fixing piece 16. When the cross bar 3 is in a folded state, the fixing piece 16 is rotated to make the fixing rod 17 snap into the U-shaped groove 18, thereby locking the cross bar 3 in a folded state, ensuring the stability of the locking, avoiding unfolding during transportation, and improving the safety of transportation;

[0043] A connecting rod 5 is also provided at the top of the first support rod 1, and a plug sleeve 21 is provided at the bottom of the connecting rod 5. The first support rod 1 is inserted into the plug sleeve 21. At the same time, a connecting screw 22 is also provided on the side wall of the plug sleeve 21. The connecting screw 22 will penetrate the first support rod 1, so as to stably connect the connecting sleeve with the first support rod 1;

[0044] A plurality of connecting hooks 6 are arranged at the top of the connecting rod 5, and a fixing spring piece 19 is arranged on a vertical inner wall of the connecting hook 6. The fixing spring piece 19 is in an L-shaped structure, one end of which is connected to the connecting hook 6, and the other end is in a free state. Anti-slip pads 20 are arranged on the other inner walls of the connecting hook. The above arrangement can ensure that the connecting hook 6 is tightly connected to the stair crossbar 3 on the cable, thereby improving the stability and safety of the connection.

[0045] When the working ladder of the present application is not in operation, the first support rod and the second support rod are in a folded state, and the cross bars are also in a folded state, so that the entire working ladder is folded to reduce the space occupied by the working ladder, which is convenient for the transportation of the working ladder;

[0046] In the working state, the first support rod, the second support rod and each of the cross rods are unfolded. Due to the limitation of the limit rod, each of the cross rods is in a stable state, that is, the cross rod is perpendicular to each of the first support rods and the second support rods; then, the cross rod is connected to the second to last or third staircase of the cable tower through the connecting hook and can be used normally;

[0047] Compared with the prior art, the present application has higher foldability, the working ladder can be conveniently transported, and the convenience of use is improved;

[0048] Secondly, the work ladder described in the present application has only one axial support rod, with a number of cross rods on both sides. The overall appearance is similar to a centipede, which simplifies the structure of the entire work ladder. It is not only beneficial to reduce the space occupied by the work ladder, but also beneficial to reduce the weight of the entire work ladder, which is beneficial to the rapid transportation of field operations and more convenient to use in the field.

[0049] The above are only preferred embodiments of the present application, and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
