Multi-legged walking robot and hydraulic driving system and control method for leg bending and stretching of multi-legged walking robot

The invention relates to a multi-legged walking robot, a hydraulic driving system for leg bending and stretching of the multi-legged walking robot and a control method, and belongs to the technical field of robots. The hydraulic driving system comprises a hydraulic cylinder, a hydraulic pump, an energy accumulator, an oil tank and a multifunctional joint control valve set. The hydraulic pump is provided with a high-pressure oil supply port and a low-pressure supply port; the multifunctional joint control valve set comprises an oil flux adjustable control valve connected between a rod oil cavity oil port and a rodless oil cavity oil port of the hydraulic cylinder, three conduction control valves that are used for independently controlling the communication states of load ports between the rod oil cavity oil port and the low-pressure oil supply port, between the rod oil cavity oil port and the high-pressure oil supply port and between the rod oil cavity oil port and the the oil tank; andthree conduction control valves used for independently controlling the communication states of load ports between the rodless oil cavity oil port and the low-pressure oil supply port, between the rodless oil cavity oil port and the high-pressure oil supply port and between the rodless oil cavity oil port and the oil tank. The hydraulic driving system with the improved structure can effectively reduce energy loss, improves the energy utilization rate, and can be widely applied to the technical field of robots.

Train collision self-turning safety table

A train collision self-turning safety table comprises a table top, guiding sliding blocks, supporting rib plates, a mechanism installation base, a torsional spring, table top locking and positioning keys and a buffer spring. The mechanism installation base is installed on a wall beside a train seat. The two supporting rib plates are installed on the mechanism installation base in parallel. The table top is installed on the two supporting rib plates. The guiding sliding blocks, the torsional spring and the buffer spring are installed below the table top and fix the table top. The seven table top locking and positioning keys are uniformly and fixedly installed on a panel of the mechanism installation base in an arc shape. The train collision self-turning safety table can buffer the collision between a passenger and the table top when a train accident happens, and therefore the response time for the passenger to conduct self-protection actively is prolonged. Through turning of the self-turning table, the contact form between the passenger and the table is changed from line contact to surface contact, and the contact area between the passenger and the table is greatly increased; and according to the Newton's laws, the pressure borne by the passenger can be effectively decreased, and the passive safety of the passenger is improved.

Multi-legged walking robot and its hydraulic drive system and control method for leg flexion and extension

The invention relates to a multi-legged walking robot and its hydraulic drive system and control method for leg flexion and extension, belonging to the technical field of robots. The hydraulic drive system includes a hydraulic cylinder, a hydraulic pump, an accumulator, an oil tank and a multi-functional joint control valve group; the hydraulic pump has a high-pressure oil supply port and a low-pressure supply port; the multi-functional joint control valve group includes a rod oil connected to the hydraulic cylinder. The oil flux adjustable control valve between the oil port of the rod oil chamber and the oil port of the rodless oil chamber is used to control the communication status of the oil port of the rod oil chamber with the low pressure oil supply port, the high pressure oil supply port and the load port between the oil tank Three conduction control valves for independent control, and three conduction control valves for independently controlling the connection state between the rodless oil chamber oil port and the low pressure oil supply port, the high pressure oil supply port and the load port between the oil tank. The hydraulic drive system improved by the structure can effectively reduce energy loss and improve energy utilization rate, and can be widely used in the field of robot technology.

A ferrule-type high-pressure oil pipe joint intelligent manufacturing equipment

The invention provides a ferrule-type high-pressure oil pipe joint intelligent manufacturing equipment, which relates to the technical field of manufacturing equipment, to solve the problem that when the existing high-pressure oil pipe joint manufacturing equipment is in use, due to vibration to remove burrs, it is easy to cause the equipment to shake, and it is easy to break the equipment. The problem of displacement occurs after long-term use, including the main body, the discharge part, the feeding port, and the support part; the main body is a rectangular structure, and the front end of the main body is provided with a rectangular outlet; the discharge part is installed at the right end of the main body. The support is used to set the bottom corner of the main body, so that the support can be in contact with the ground, and then firmly in contact with the ground. When the device is in use, the spring pushes the moving rod to move downward, so that the contact It can always be in contact with the ground. Since the contact piece is made of rubber and the bottom is provided with a wedge-shaped groove, it can effectively contact with the ground, thereby buffering the impact force and avoiding abnormal noise or displacement caused by the contact between the support piece and the ground.
