[0002] Live working is an important means of testing, repairing and renovating power equipment. It has made great contributions to improving power supply reliability, reducing power outage losses and ensuring power grid safety. Live working has very strict requirements on the technical level and proficiency of operators, climatic conditions, safety protection equipment, etc. Due to concerns about safety hazards, lack of appropriate personal safety protection equipment and insufficient training in live working techniques, some areas have restricted the content of live working in substations, resulting in frequent power outages in substations and failure to meet transmission and distribution reliability indicators, which has caused great economic losses to power companies and brought great inconvenience to people's lives and production.

[0003] Traditional live working equipment has safety hazards during operation, such as the risk of electric shock to operators or accidents caused by equipment failure. Traditional equipment is bulky and complicated to operate, and even requires the cooperation of multiple workers to complete the operation. Live working usually occurs around high-voltage electrical equipment, and the environment is complex and dangerous. Traditional equipment is easily disturbed or damaged in complex environments, and may not even be able to adapt to conditions such as high voltage, high current or bad weather. At the same time, there is a problem of low operating efficiency, especially when maintaining complex power equipment, which requires a lot of time and energy. Due to the high frequency of use or harsh working environment, it is prone to failure or wear and tear, and cannot cope with rapidly changing grid operating conditions or complex operating tasks.

[0051] Working principle: First of all, the equipment mainly provides personnel lifting operations for live maintenance. It can use its own multi-terrain displacement structure to move to different areas for live maintenance operations. The lifting platform structure composed of the main fixing mechanism 9, the lateral positioning mechanism 10 and the folding and extension mechanism 11 is installed in the fixed frame 1, and the lifting platform structure is fixed inside the fixed frame 1 by using the bearing platform 4 arranged inside the fixed frame 1, and is loaded by multiple groups of support beams 3 at the bottom of the fixed frame 1, and the main fixing mechanism is used. The mounting adapter mechanism 6 installed on the four ends of the fixed frame 1 on both sides is used to cooperate with the load bearing. The buffer shock absorbing mechanism 7 is fixed as a whole on the link seat 61 included in the mounting adapter mechanism 6. The link seat 61 can be rotated by the hinge page 1 62 and the hinge page 2 63. The rotation relationship is formed by cooperating with the positioning damping rod 64 installed between the link seat 61 and the main fixing mechanism fixing frame 1 to form the steering ability, so as to achieve the independent expansion between each buffer shock absorbing mechanism 7, so as to cooperate with the placement of lifting platform structures of different shapes. The support feet 65 included in the installation adapter mechanism 6 arranged on the four sides cooperate with its own crawler running group to be placed on the ground displacement operation in the operation area, and follow the operation of the buffer shock absorbing mechanism 7. When the lifting platform structure is started and operated, an inertial force will be generated and transmitted to the base plate 2, and the inertial force will make the base plate 2 swing together. The movement of the base plate 2 will drive the buffer shock absorbing mechanism 7 fixed on the four sides of the top to operate. The fixed plate 71 included in the buffer shock absorbing mechanism 7 will follow the swing because it is fixed on the base plate 2, and the fixed plate 71 will follow the swing. The buffer damping rod 74 installed inside the fixed frame 72 through the rotation of the main rotating shaft seat 77 will start to operate and correspondingly retract the hydraulic output rod, and the rotating end block 711 installed on the top of the hydraulic output rod of the buffer damping rod 74 will drive the rotating linkage frame 79 installed thereon to be retracted, and the movement of the linkage frame 79 and the rotation of the installed secondary linkage rod 78 and the main linkage rod 76 make the linkage frame 79 only realize vertical movement, and the retaining spring 710 installed on the buffer damping rod 74 cooperates with the buffer damping rod 74 to form a damping buffering effect, so that the inertial force is buffered and eliminated, and cannot reach the fixed frame 1 fixed by the linkage frame 79 through the bottom docking plate 712, so that the lifting platform structure installed inside the fixed frame 1 will not be affected by the inertial force, and at the same time, the installation adapter mechanism 6 is installed The included support legs 65 operate along with the buffer shock absorbing mechanism 7 to achieve comprehensive damping and shock absorbing treatment during operation and equipment displacement, thereby improving the multi-terrain delivery capability of the equipment. Four independent buffer shock absorbing mechanisms 7 are installed on the main fixing mechanism fixing frame 1 through correspondingly configured installation adapter mechanisms 6. A set of fixing cavities 5 are respectively arranged on the front and rear sides of the fixing frame 1, and the concentrated heat absorption mechanisms 8 respectively installed inside the two sets of fixing cavities 5 provide heat absorption and cooling functions for the lifting platform structure. The inlay seat 81 included in the concentrated heat absorption mechanism 8 is fixed inside the fixing cavity 5, and is used to install C-shaped heat absorption tube 1 82, C-shaped heat absorption tube 2 83, C-shaped butt joint pipe 84 and butt joint elbow 85. The C-shaped heat absorption tube 1 82 and the C-shaped heat absorption tube 2 83 are evenly laid on the inlay seat 81.And the right input end of the C-shaped heat absorption tube 1 82 is connected to the right output end of the C-shaped heat absorption tube 2 83 through a C-shaped butt joint tube 84, and the right output end of the C-shaped heat absorption tube 1 82 is connected to the right input end of the C-shaped heat absorption tube 2 83 through a butt joint elbow 85, forming a group of flat and cyclically unfolded heat absorption pipes, the heat absorption pipes are made of rock wool and glass wool, and the inner parts of the two groups of concentrated heat absorption mechanisms 8 directly contact the lifting platform structure fixed inside the fixed frame 1, while the heat absorption plate 86 on the base plate 2 and the heat absorption side plates 87 on both sides of the fixed frame 1 continuously absorb heat in a fitted form, and the outer part extends out of the fixed frame 1 through the fixed cavity 5. When the lifting platform structure operates for a long time and generates heat, The heat will be absorbed by the two groups of concentrated heat absorption mechanisms 8, and the two groups of concentrated heat absorption mechanisms 8 will then cool down autonomously through the parts extending out of the fixed frame 1, and cooperate with the multiple groups of support beams 3 installed at the bottom of the fixed frame 1 to form a hollow ventilation structure, which provides heat absorption and cooling for the lifting platform structure and reduces the impact of heat on the external environment. A group of fixed cavities 5 are respectively arranged on the front and rear sides of the fixed frame 1, and the concentrated heat absorption mechanisms 8 respectively installed in the two groups of fixed cavities 5 provide heat absorption and cooling function for the lifting platform structure. The inlay seat 81 included in the concentrated heat absorption mechanism 8 is fixed in the fixed cavity 5, and is used to install C-shaped heat absorption tube 1 82, C-shaped heat absorption tube 2 83, C-shaped butt joint pipe 84 and butt elbow 85. The C-shaped heat absorption tube 1 82 and the C-shaped heat absorption tube 2 83 are both The heat absorbing pipes are evenly laid on the inlay seat 81, and the right input end of the C-shaped heat absorbing pipe 1 82 is connected to the right output end of the C-shaped heat absorbing pipe 2 83 through a C-shaped butt pipe 84, and the right output end of the C-shaped heat absorbing pipe 1 82 is connected to the right input end of the C-shaped heat absorbing pipe 2 83 through a butt elbow 85, forming a group of flat and cyclically unfolded heat absorbing pipes, the heat absorbing pipes are made of rock wool and glass wool, and the inner parts of the two groups of concentrated heat absorbing mechanisms 8 directly contact the lifting platform structure fixed inside the fixed frame 1, while the heat absorbing plate 86 on the base plate 2 and the heat absorbing side plates 87 on both sides of the fixed frame 1 continuously absorb heat in a fitted form, and the outer part extends out of the fixed frame 1 through the fixed cavity 5. When the lifting platform structure is long When the time runs and heat is generated, the heat will be absorbed by the two groups of concentrated heat absorption mechanisms 8, and the two groups of concentrated heat absorption mechanisms 8 will then cool down autonomously by extending the part of the fixed frame 1, and cooperate with the multiple groups of support beams 3 installed at the bottom of the fixed frame 1 to form a hollow ventilation structure, which provides heat absorption and cooling for the lifting platform structural components to ensure the stable operation of the lifting equipment. At the same time, the main fixing mechanism 9, the lateral positioning mechanism 10 and the folding and extension mechanism 11 serve as the main lifting structure of the equipment. By activating the main fixing mechanism 9 fixed on the support beam 3, the diesel engine 94 fixed inside the component frame 91 is started and drives the drive gear 95 installed at its output end to rotate. The rotation of the drive gear 95 adjusts the overall lateral angle of the lateral positioning mechanism 10.The driving gear 95 and the interlocking gear plate 102 meshing with it drive the rotating shaft of the transverse shaft seat 101 to rotate along the fixed bearing 93 on the top of the component frame 91, thereby adjusting the orientation angle of the raised folding arm and automatically positioning the most suitable maintenance operation angle. After completing the basic adjustment of the angle, the emergency power maintenance personnel can enter the operating platform 118 through the auxiliary ladder and carry the power maintenance equipment with them, and then activate the folding and extension mechanism 11, the hydraulic drive component 113 is started to rotate itself along the transverse shaft seat 101, and the output end drives the rotating shaft seat 112 and the lower arm 111 to rotate and unfold along the transverse shaft seat 101 to form a certain unfolding height and inclination angle, and then the hydraulic pressure inside the lower arm 111 is activated. The drive assembly 2 114 makes itself rotate along the lower arm 111, and the output end pushes the rotating shaft 116 and the upper arm 115 to rotate and unfold along the lower arm 111, forming a certain unfolding height and tilt angle again, so that the end of the upper arm 115 rotates the operating platform 118 installed by the rotating end seat 117 to reach a suitable emergency power maintenance height for power transmission equipment maintenance operations. The lower arm 111 and the upper arm 115 can also be folded and retracted along the horizontal shaft seat 101 by starting the hydraulic drive assembly 2 114 and the hydraulic drive assembly 1 113. According to different height requirements, multiple sets of stacked upper arms 115 and the folded and unfolded heights of the upper arms of the hydraulic drive assembly 2 114 can meet different height requirements.
