Example 1

[0032] like Figures 1 to 3As shown together, this embodiment provides a power engineering repair ladder, including a chassis 1 and a suction cup base 2, wherein the suction cup base 2 is fixedly mounted at the bottom of the chassis 1, and an extension mechanism 3 is arranged at the top of the chassis 1, wherein the extension mechanism 3 includes an extension member 31, and the extension member 31 includes a load base 311, and the load base 311 is movably connected to the top of the chassis 1, and a limit block 312 is fixedly mounted on the surface of the load base 311, and the limit blocks 312 are distributed on both sides of the load base 311;

[0033] A first ladder body 313 is disposed between the limit blocks 312. The first ladder body 313 is disposed parallel to the load base 311, and guide grooves 314 are provided on both sides of the first ladder body 313. The first ladder body 313 is movably connected to the inner side of the limit blocks 312 through the guide grooves 314.

[0034] A support member 4 is also provided on the top of the chassis 1, and a load base 311 is installed on the outside of the support member 4. The load base 311 is in an inclined state when in use, and a cabin for installing equipment is opened inside. The first ladder body 313 is movably connected to the outside of the load base 311 through a limit block 312, and when in use, the first ladder body 313 is kept parallel to the load base 311 through a guide slot 314 under the restriction of the limit block 312, thereby increasing the maximum height that the device can reach.

[0035] A transmission guide rail 315 is provided at the bottom of the first ladder body 313, and reinforcement blocks 316 are provided on both sides of the transmission guide rail 315. The transmission guide rail 315 is fixedly installed on the inner side of the first ladder body 313 through the reinforcement blocks 316. A transmission slider 317 is movably connected to the inner side of the transmission guide rail 315. The angle between the transmission guide rail 315 and the first ladder body 313 is ninety degrees. The transmission slider 317 can move in the transmission guide rail 315 in a direction parallel to the transmission guide rail 315.

[0036] When it is necessary to increase the highest point that the device can reach, the chassis 1 is moved to the bottom of the maintenance area and fixed to the ground by the suction cup base 2. The motor 319 is activated so that the output shaft of the motor 319 drives the swing arm 318 to rotate with the motor 319 as the center, so that the transmission slider 317 connected to the swing arm 318 moves in the groove in the transmission guide rail 315 in a direction parallel to the transmission guide rail 315. As the angle of the swing arm 318 changes, the transmission slider 317 drives the transmission guide rail 315 to move through the bottom of the first ladder body 313 connected to the reinforcement block 316 while moving. At the same time, the guide grooves 314 on both sides of the first ladder body 313 are restricted by the limit block 312 to ensure movement in a direction parallel to the load base 311, thereby increasing the highest reaching height of the device and ensuring smooth maintenance work. Example 2

[0037] like Figures 1 to 4 The second embodiment of the present invention is shown together, and the difference between the second embodiment and the first embodiment is as follows:

[0038] The extension mechanism 3 also includes an adjusting member 32, which includes a second ladder body 321. The bottom of the second ladder body 321 is hinged with an adjusting slider 322. The adjusting slider 322 is movably connected to both sides of the chassis 1. The adjusting slider 322 is threadedly connected to the chassis 1 through an adjusting screw 323. The angle between the second ladder body 321 and the chassis 1 can be adjusted by changing the position of the adjusting slider 322 on the chassis 1. The inner side of the adjusting slider 322 is opened with a thread that is compatible with the adjusting screw 323, and the adjusted screw 323 runs through the whole.

[0039] The bottom of the second ladder body 321 is also movably connected with a traction shaft 324 , and the adjusting sliders 322 are connected through the traction shaft 324 . The traction shaft 324 connects the adjusting sliders 322 at the bottom of the second ladder body 321 , so that the adjusting sliders 322 always keep moving synchronously.

[0040] The support member 4 includes a flip seat 41, which is fixedly mounted on the top of the chassis 1. A third ladder body 43 is arranged on the inner side of the flip seat 41. The third ladder body 43 is hinged to the flip seat 41 through a deflection axis 42. The bottom of the third ladder body 43 can be deflected at the top of the chassis 1 with the deflection axis 42 as the center and under the restriction of the flip seat 41, so as to adjust the angle deflection of the third ladder body 43.

[0041] The load base 311 is fixedly mounted on a side of the third ladder body 43 away from the second ladder body 321 , and the load base 311 and the third ladder body 43 are arranged parallel to each other. When the angle of the third ladder body 43 is deflected, the parallelly arranged load base 311 and the third ladder body 43 are always deflected at the same angle.

[0042] A hinge shaft 44 is provided at one end of the third ladder body 43 away from the deflection shaft 42 , and the third ladder body 43 is hinged to the second ladder body 321 via the hinge shaft 44 . When the third ladder body 43 and the second ladder body 321 are hinged, an inverted V-shaped support structure is formed.

[0043] During use, the adjusting screw 323 threadedly connected to the chassis 1 is rotated, so that the adjusting slider 322 with a corresponding thread on the inner side moves along the groove in the chassis 1, and because it is connected by the traction shaft 324, the adjusting sliders 322 can keep moving synchronously, and the inclination angle between the second ladder body 321 hinged in the adjusting slider 322 and the chassis 1 is changed, thereby changing the inclination angle between the third ladder body 43 hinged to the second ladder body 321 through the hinge shaft 44 and the chassis 1, so that the maintenance inclination angle of the device can be adjusted according to different usage requirements and the floor space can be reduced. When in use, when the load base 311 is used for maintenance, the device adopts a telescopic placement method. When the third ladder body 43 is hinged to the second ladder body 321 through the hinge shaft 44, and the third ladder body 43 is restricted by the flip seat 41, it deflects with the deflection axis 42 as the original center, and together with the hinged second ladder body 321, it forms an inverted V-shaped support structure, so that the device is relatively stable when used, ensuring the safety of the maintenance personnel.

[0044] It should be understood that the purpose of these embodiments is only to illustrate the utility model and is not intended to limit the protection scope of the utility model. In addition, it should also be understood that after reading the technical content of the utility model, those skilled in the art can make various changes, modifications and / or variations to the utility model, and all of these equivalent forms also fall within the protection scope defined by the claims attached to this application.
