The utility model relates to machining equipment base field especially a kind of machining equipment base with shock pad. Including base, the surface of the four around base is equipped with adjusting structure, the adjusting structure includes several reserved slots, several the reserved slots are set on base, the inner wall of the reserved slot is connected with adjusting lever, the lower end of the adjusting lever is rotatably connected with support plate, the upper surface of the support plate is fixedly connected with slide bar, the surface of the slide bar is slidably connected with base, the side of the support plate is equipped with butt joint groove, the inner wall of the butt joint groove is slidably connected with butt joint block, the lower surface of the butt joint block is fixedly connected with shock pad. The utility model provides a kind of machining equipment base with shock pad, and the height of support plate can be accurately adjusted by rotating adjusting lever, equipment leveling is realized;Operation positioning rod, support plate and shock pad can be conveniently disassembled and assembled, and the advantages of convenient user maintenance.

The present application relates to the field of tractor suspension, and particularly relates to a tractor suspension automatic leveling device and a control method thereof. The tractor suspension automatic leveling device comprises a mounting frame, a plurality of connecting beams are fixedly connected to the mounting frame, a damping leveling system is connected to the mounting frame, a suspension frame is connected to the damping leveling system, a horizontal plate is fixedly connected to the suspension frame, the suspension frame is used for mounting a machine tool, a double-shaft inclination sensor is mounted on the horizontal plate, and a rotating leveling system is arranged. The leveling and damping functions are integrated in the same oil cylinder. When the impact acceleration exceeds the set threshold, the inertia sensitive valve core is automatically opened, the main oil cylinder cavity is communicated with the energy storage cavity, the millisecond mechanical impact absorption is realized, the sensor and the controller are not needed to intervene, the response speed is superior to that of the traditional electric control damping scheme, after the impact, the hydraulic oil in the energy storage cavity slowly returns to the original position through the one-way throttling valve, the leveling and damping functions are cooperatively worked, and the posture deviation is avoided.

The utility model belongs to building construction technical field especially a kind of building construction wall surface leveling auxiliary device, including wall rest board, the both ends of wall rest board top outer wall are all fixedly connected with positioning plate, and wall rest board one side inner wall is rotatably connected with array distribution's pulley, wall rest board one end outer wall is slidably connected with baffle, and the inner wall on baffle is screwed with screw rod, and the outer wall of screw rod one end is rotatably connected on the outer wall of wall rest board one side.The utility model solves the problem of unstable positioning by the cooperation of wall rest board, positioning plate and pulley, ensures that the device moves smoothly, avoids the insufficient wall flatness caused by positioning deviation in traditional construction, improves the leveling accuracy, solves the tool adaptability problem by the combination of scraper and extension blade, loosens fastening knob to adjust the extension blade extension length along the strip-shaped groove, without frequent tool change, and the first sawtooth and second sawtooth reduce mortar adhesion, reduce cleaning difficulty, effectively improve construction efficiency.
