[0036] Example and principle explanation: Open the cap on the three-way connecting pipe of the hydraulic jack, fill the hydraulic device with hydraulic oil. When adding hydraulic oil, the piston of the hydraulic jack is in the fully extended state, and the hydraulic pump under the foot is in the fully retracted state. After filling with hydraulic oil, replace the cap on the three-way connecting pipe. The left and right feet of the person carrying the load are put into the shoe upper formed by the straps of the left and right foot walking device, and the straps formed by the shoe upper are used to fix the left and right feet of the person carrying the load. After adjusting the lower leg length adjustment tube to the optimal position, fix the lower leg length adjustment tube with the lower leg length adjustment fixing bolt. After adjusting the thigh length adjustment tube to the optimal position, fix the thigh length adjustment tube with the thigh length adjustment fixing bolt. Fix the thigh of the person carrying the load with the straps on the thigh length adjustment tube and the thigh shell. Fix the lower leg of the person carrying the load with the straps on the lower leg shell. Put the left and right shoulder straps on the left and right back of the person carrying the load, adjust the shoulder straps and fix the load-bearing moving device. Another person puts the goods to be moved on the load-bearing chair's load-bearing plate and fixes the goods. The person carrying the weight lifts their left foot, causing the piston of the hydraulic pump beneath it to fully extend, and then moves their left foot a certain distance. After moving their left foot, they then move it downwards, placing it on the movable cover of the hydraulic pump housing. The force on the movable cover is transmitted to the piston of the hydraulic pump beneath it. The piston moves downwards, compressing the hydraulic oil below it. This hydraulic oil pushes the hydraulic oil in the hydraulic hose to the hydraulic jack on the right side, causing the piston inside the right-side hydraulic jack to move to the left, thus moving the weighted chair to the left. The three pistons of the hydraulic pump inside the left-foot hydraulic pump housing... The volume of hydraulic oil required to compress downwards is equal to the volume of the right-side hydraulic jack fully retracted and extended. Since the length of the load-bearing plate and the backrest are equal to the width of the weighted chair, the difference between the height inside the hydraulic jack pump housing and the thickness of the load-bearing frame side panel, the thickness of the first layer of plugs, and the thickness of the pump housing end cap ring is one-third of the width of the weighted chair. The difference between the height inside the first layer of piston columns and the thickness of the load-bearing frame side panel, the thickness of the second layer of plugs, and the thickness of the first layer of piston end cap ring is one-third of the width of the weighted chair. The difference between the height of the third piston column and the thickness of the second piston end cap ring is one-third of the width of the weighted chair; the difference between the height of the third piston column and the thickness of the second piston end cap ring is one-third of the width of the weighted chair; therefore, the total extension length of all pistons on the right side of the hydraulic jack is equal to the width of the weighted chair; the length of the backrest of the weighted chair is equal to half the width inside the weighted frame, and the length of the load-bearing plate of the weighted chair is equal to the length of the backrest, so the width of the weighted chair is equal to half the width inside the weighted frame; therefore, when the right side of the hydraulic jack is fully extended, it is just... The weighted chair is pushed to the far left of the weighted frame. Since the lower surface of the weighted frame connects to the upper surfaces of the connecting plates on the left and right foot travel devices at points one-quarter and three-quarters of the length, respectively, when the weighted chair moves to the far left of the weighted frame, the weight on the chair is precisely pressed onto the left foot travel device. The weight is then transferred to the ground through the left foot travel device. The movement principle of the person carrying the weight is the same as that of the left foot. The direction of movement of the weighted chair when the right foot moves is opposite to that when the left foot moves. When a person carrying a load walks, the anti-slip spikes on the lower surface of the anti-slip plastic sheet under the hydraulic pump box prevent slipping. The person's feet are fixed to the hydraulic box, and the foot axle sleeves on the hydraulic box can rotate around the foot axle, allowing the person's toes to move freely upwards and downwards. When the weight of the weight-bearing chair is transferred downwards to the anti-slip gears of the walking device, the anti-slip gears insert into the gaps between the anti-slip internal gear racks. Because the anti-slip internal gear racks are fixed, they prevent the thigh length adjustment tube from slipping. The difference between the diameter of the circular holes on the inner and outer cover plates of the knee cavity shell and the diameter of the connecting rod is slightly greater than the depth at which the anti-slip internal gear rack engages with the anti-slip gears. The upper part of the inside of the knee cavity shell is not... It has an anti-slip internal gear rack, and when the thigh is raised, the knee cavity shell can rotate freely with the lower leg of the person carrying the weight; the ball moves inside the ball shell, and the cap and ring of the ball shell can prevent the ball from slipping out during movement; because the ball limiting plate surrounds the ball: on the inner side, the middle of the left and right sides, one-quarter of the way up from the bottom, near the middle of the rear side, and on the outer side, the middle of the left and right sides, one-quarter of the way up from the bottom; the ball limiting plate is located below the ring of the ball shell; therefore, the ball limiting plate can limit the range of movement of the ball, making the ball move a lot forward and a little less left and right, and when the thigh shell connected to the ball is perpendicular downward, the ball cannot rotate backward; The bottom rollers on the underside of the weightlifting chair reduce the thrust required for left and right movement and also help to position the chair vertically. The grooves of the back rollers on the weightlifting chair are located on the slide rail, which prevents the back rollers from sliding backward, thus preventing the weightlifting chair from tipping backward.
