The utility model discloses an earth excavation foundation pit protection device capable of being positioned and supported, and relates to the technical field of foundation pit protection devices, the earth excavation foundation pit protection device comprises a protection plate, fixed ground inserts, insertion blocks and splicing blocks, the fixed ground inserts are welded on the two sides of the bottom end of the protection plate, the two insertion blocks are fixed on one side of the protection plate, and the splicing blocks are fixed on the other side of the protection plate. And two splicing blocks are fixed on the other side of the protection plate. The adjusting rod is screwed to drive the moving plate to move horizontally, on one hand, the adjusting rod can extend out of the protection plate conveniently, so that the adjusting rod can be inserted into soil around a foundation pit to increase the contact force between the protection plate and the foundation pit, and on the other hand, the moving rod descends under the action of the push block and the sliding block, so that the foundation pit is protected. And thus, the descending block pushes the moving block to do horizontal movement, then the fixing rod can stretch out of the interior of the fixing ground insert conveniently, the soil grabbing capacity of the fixing ground insert is improved, and then the stability of the protection plate during use is improved.

The application discloses a patch equipment for ammonia gas sensor production, which comprises a main body, a fixing seat fixedly connected to the upper side of the main body, a positioning device arranged above the main body, a mounting frame and a pressing plate arranged above the positioning device, and a support adjusting assembly comprising the positioning device and arranged above the fixing seat. The patch equipment for ammonia gas sensor production can rotate the output shaft of the motor, stably move the limiting column, adjust the position of the fixing block, position the ammonia gas sensors of different sizes, adjust the position of the support block, position and support the ammonia gas sensors of different sizes, support the ammonia gas sensors after positioning, stably patch the ammonia gas sensors, and reduce production cost without setting different fixing die seats for different ammonia gas sensors.

The application is suitable for the field of plate processing, and provides a cross web plate root cleaning machine, which comprises a main frame, a lower bracket and an upper bracket which are installed on the main frame and correspondingly arranged up and down; an obliquely arranged cutter head is installed at a predetermined position in the middle of the lower bracket, and the cutter head is installed on a cutter head support; a guard plate is installed on the cutter head support; a plurality of obliquely arranged auxiliary support rollers which assist in positioning the workpiece are arranged on the lower bracket and the upper bracket; the auxiliary support rollers arranged on the lower bracket are symmetrically distributed on the left and right sides of the lower bracket; an included angle A is formed between the auxiliary support rollers arranged on the left and right sides; thus, the cross web plate can be supported by the auxiliary support rollers and the guard plate, which can conveniently position and support the workpiece, avoid the influence of the angle deviation of the workpiece on the root cleaning work, and avoid the end face of the cutter head from contacting the plate surface to cause the plate surface to be scratched.

This utility model provides an oil suction filter, including a housing and a filter assembly disposed within the housing. The housing includes a bottom shell and a cover plate, the cover plate being a light-transmitting element and the bottom shell being a light-absorbing element. The filter assembly includes a filter screen frame and a filter screen disposed within the filter screen frame. The edges of the bottom shell and the cover plate are laser-welded together to form a sealed connection along the edges, and the edges of the filter screen frame and the cover plate are laser-welded together to form a sealed connection along the edges. In this utility model, the laser-welded structure and double seals achieve good positioning and support, ensuring a tight fit between the cover plate, frame, and housing, effectively preventing dust and impurities from entering the filter interior.
