Motor vehicle pneumatic jacklift system

A permanently mounted pneumatic jack (jacklift) system for motor vehicles, as well as an impact wrench for removing and installing lug nuts. The system provides a quick and safe means of lifting one or more tires off the ground for replacement of a spare or rotating the tires on a motor vehicle. The present invention comprises two or more (typically four) pneumatic jacks, a system ON/OFF switch, an air compressor, a 120-psi air tank, air lines (hoses), individual jack extend/retract switches, jack position-locking pins, safety-locking pins, and impact wrench. Each jack can be locked in a horizontal stowaway or vertical operational position. The jack is cylindrical shaped with a telescopic body that can be extended or retracted as needed to raise and lower the vehicle. A solid cylindrical lift rod slides inside a cylindrical outer housing with a high-pressure seal means used to maintain pressure on the support rod. A ground support foot (plate) is mounted on the lower end of the solid cylindrical lift rod to provide sufficient traction with the ground to support the lifting process. A quick release air coupler is included on the pneumatic chamber to support the use of an air hose and impact wrench. An extend/retract toggle switch is included on each jack to control a solenoid valve to allow the air to flow into the jack. A quick release safety-locking pin is used to mechanically pin the solid cylindrical lift rod to the outer housing once the desired height is achieved to assure that the vehicle does not fall down in the event of a high-pressure air loss, thereby providing safety to the person(s) working around the vehicle. An air compressor located in the engine compartment of the vehicle is mechanically belt-driven off the engine. A high-pressure air line carries the air to a high-pressure (at least 120-psi) air tank located in the trunk or other suitable storage area on the vehicle. Separate air lines extend from the air tank to the individual jacks.

The utility model relates to the technical field of automobile parts, in particular to an automobile self-rescue unit for an automobile to get rid of an accident or turn around in situ when the automobile gets stuck. According to the technical scheme, the automobile self-rescue unit comprises a fixing mechanism, a lifting mechanism and a supporting mechanism, wherein the lifting mechanism is particularly a hydraulic lifting device, and a hydraulic cylinder of the hydraulic lifting device is connected with the fixing mechanism via a bearing capable of allowing the hydraulic cylinder to rotate correspondingly; a lifting rod of the hydraulic lifting device rises from the top end thereof to be fixedly connected with the supporting mechanism; the supporting mechanism is propped against the ground to jack up the automobile; and the lifting rod rotates relative to the hydraulic unit body, so that the wheel can be deviated from the upper part of a pit, and then the automobile can be put down. Accordingly, the automobile self-rescue unit saves the trouble in manually pushing or pulling the automobile and is fast, convenient and practical; a lifting jack is not required for jacking up the automobile and replacing the tires; and the automobile self-rescue unit can effectively prevent the fatigue and contraction of the shock absorption system, turn the automobile around in situ by 180-degree rotation and protect the chassis of the automobile.

Intelligent anti-rollover control system for oil tank truck and use method

The invention discloses an intelligent anti-rollover control system for an oil tank truck and a use method. The intelligent anti-rollover control system comprises a truck frame, a tank body, multi-dimensional pneumatic pressing plate adjusting devices, a combined pressing plate, annular gravity center adjusting devices, six-dimensional posture adjusting bionic wheel legs, a central control unit, a tank body gravity center controller and tank truck sensors. The use method is mainly characterized as follows: the central processing unit performs coordination control on the tank body gravity center controller and a wheel leg posture adjusting controller; the tank body gravity center controller performs coordination control on a pressing plate adjusting controller, a pressing plate controller and an annular gravity center adjusting controller; the wheel leg posture adjusting controller performs six-dimensional posture adjusting on the six-dimensional posture adjusting bionic wheel legs. The intelligent anti-rollover control system can realize real-time online monitoring and control of the gravity center of a chassis of the oil tank truck and the gravity center of the tank body of the oil tank truck, prevent rollover when the oil tank truck is disturbed by the bad road surface and the outside in a high-speed running state and remarkably improve the running stability, safety and the anti-rollover capacity of the oil tank truck.

Automotive Construction Engine and Lifting Column for a Contruction Engine

Disclosed is an automotive road construction engine (1), particularly a recycler or a cold stripping machine, comprising an engine frame (4) that is supported by a chassis (2), a working roller (6) which is stationarily or pivotally mounted on the engine frame (4) and is used for machining a ground surface or road surface (24). The chassis (2) is provided with wheels (10) or tracked running gears which are connected to the engine frame (4) via lifting column (14) and are vertically adjustable relative to the engine frame (4). The lifting columns (14) are composed of two hollow cylinders (13, 15) that can be inserted into each other, are used as a guiding unit, and preferably coaxially accommodate at least one piston-cylinder unit (16) therein for vertical adjustment purposes. Each individually vertically adjustable lifting column (14) is equipped with a device (18) for measuring the actual vertical state of the lifting column (14). Said measuring device (18) is coupled to lifting column (14) elements that can be adjusted relative to each other according to the vertical position in such a way that the measuring device (18) can continuously detect a path signal regarding the vertical position of each lifting column (14). A controller (23) which receives the measured path signals of the measuring devices (18) of all lifting columns (14) regulates the vertical state of the lifting columns (14) in accordance with the measured path signals of the measuring devices (18) and/or the changes thereof over time.

Movable Platform for Replacing Battery and Quick Replacing System

Disclosed are a movable battery replacing platform (103) and a quick replacing system (100), wherein the movable battery replacing platform (103) comprises: a travel-driving portion (106) used for driving the movable battery replacing platform (103) to move on the ground; a lifting portion (107) mounted on the travel-driving portion (106), for lifting a battery during the replacement of the battery; and a battery mounting portion (108) mounted on the top of the lifting portion (107), for placing a battery to be replaced or a replaced battery, wherein the battery mounting porting (108) is provided with a battery replacing device. The device can use an unlocking device (50) to unlock a battery locked on the bottom of an electric vehicle, automatically aligning an unlocking point of a battery locking mechanism and realizing automatic unlocking in the movement. The whole process is fully automated without manual intervention and can improve battery replacement efficiency. In addition, the angle of an upper board (10) relative to the battery unlocking position can be adjusted by a movement actuating device, so that the unlocking point of the battery can automatically fit where the movable battery replacing platform (103) remains still, so as to further improve unlocking efficiency.
