This utility model discloses an inclined pile support structure for retaining walls, comprising three parts: a retaining wall, a beam, and an inclined pile support. The beam is a reinforced concrete structure located at the top of the retaining wall. The upper end of the inclined pile support is a steel pipe pile, and the lower end is a high-pressure jet grouting pile. The high-pressure jet grouting pile is located below the foundation pit surface. The upper end of the steel pipe pile is anchored into the beam, and the lower end is inserted into the high-pressure jet grouting pile. A first sealing steel plate plug is installed at the upper end of the steel pipe pile, and a second sealing steel plate plug is installed at the lower end of the steel pipe pile. The second sealing steel plate plug is provided with grouting holes. A waterproof steel plate is welded around the steel pipe pile at the cross-shaped steel plate pile tip located in the foundation pit. The waterproof steel plate is fixed in the foundation pit layer. The lower end of the steel pipe pile is a spherical grout bubble.

The utility model relates to the technical field of photovoltaics and semiconductors, in particular to a sheet thickness measuring device and a sheet thickness measuring system, and aims to solve the problem that the sheet thickness measuring device can cause sheet contact damage or low measurement precision. The sheet thickness measuring device comprises a driving assembly and a measuring assembly. The measuring assembly is configured to measure one or more first distances from the bearing plane to the measuring assembly and one or more second distances from one side of the sheet away from the bearing plane to the measuring assembly, so as to calculate the thickness of the sheet based on the one or more first distances and the one or more second distances. The sheet thickness measuring device does not need to be contacted with the sheet, so that contact damage is avoided. Besides, the sheet thickness measuring device can output the first distance and the second distance, so that the first distance and the second distance can be used for analysis and calculation, the thickness does not need to be determined by using an interference principle or a spectrum principle, the influence of ambient light is small, and the measuring precision of the sheet thickness measuring device is improved.

The invention discloses an electric red wine bottle opener, and relates to the technical field of bottle openers, the electric red wine bottle opener comprises a main shell, the outer part of the main shell is provided with a charging port, and the inner part of the main shell is provided with a pressurizing bottle opening structure; the pressurizing bottle opening structure comprises three partition plates, a rechargeable battery, an air pump, an air conveying steel pipe, two electric push rods, a push plate and a movable plate, the push plate is fixedly connected with one ends of the electric push rods, sliding holes are formed in the two sides of the outer portion of the main shell, and the two ends of the movable plate are arranged on the inner sides of the sliding holes of the main shell in a sliding mode. Two first springs are arranged between the movable plate and one of the partition plates, and fixing rods are fixedly arranged on the two sides of the outer portion of the movable plate. According to the electric bottle opener for the red wine bottle, the cork can be ejected out to complete falling work by pressurizing the interior of the red wine bottle, and in the process, the cork cannot be broken or wood chips cannot fall off.

The invention relates to the technical field of motor overhauling, in particular to a large motor disassembling, hoisting and overhauling method. The method comprises the following steps: firstly, preparing technical data and standard tools, then sequentially measuring and recording a gap between bearing bushes of an upper roller motor and a lower roller motor, dismantling shielding structures such as a middle connecting shaft, a platform walking board and an A-shaped frame, dismantling accessory parts of the lower roller motor and marking relative positions, and after measuring an air gap between a stator and a rotor, completing the operation of the upper roller motor and the lower roller motor. The stator and the rotor are safely decomposed and purged and checked in a manner of cooperative lifting of two 75-ton cranes and leveling of a chain block, and finally, the shim is adjusted according to original data after reverse-sequence reinstallation, so that debugging and test running are completed. According to the method, the heavy load problem is solved through double-machine cooperative hoisting, precise assembly is achieved through the processes of measurement, recording, application and adjustment, gap deviation and contact damage are avoided, the overhaul safety, stability and efficiency are improved, and the method is suitable for industrial field overhaul of the large-scale heavy-load motor.

This utility model discloses a laser cutting anti-shake device and laser cutting equipment, relating to the technical field of laser cutting equipment. The laser cutting anti-shake device includes a worktable, a laser cutting component, and a nozzle. The worktable has a placement surface, the laser cutting component is positioned above the placement surface, and the nozzle is positioned at the end of the laser cutting component near the placement surface. The nozzle has a main air outlet channel and an auxiliary air outlet channel. The auxiliary air outlet channel is arranged circumferentially around the main air outlet channel, and an air outlet is provided on the side of the auxiliary air outlet channel closest to the placement surface. The auxiliary air outlet channel, along the direction from the nozzle to the placement surface, is inclined from the side closest to the central axis of the main air outlet channel to the side furthest from the central axis of the main air outlet channel.
