The utility model discloses a bidirectional limiting door limiter and a door body structure. The bidirectional limiting door limiter comprises a limiting rod and a clamping seat plate, the limiting rod is movably assembled on a door plate structure, and the clamping seat plate is arranged on a door frame column provided with a hinge; a locking rod is arranged on the limiting rod; a limiting groove matched with the locking rod is formed in the clamping seat plate; the locking rod can be clamped into the limiting groove to achieve limiting at different angles. By means of the scheme, when the door plate structure needs to be limited, the locking rod is clamped into the limiting groove in the preset position, locking of the door plate structure at different angle positions is achieved, and therefore the situation that after the door plate structure is opened, collision with a door frame or an internal rigid structure of skid-mounted equipment occurs due to accidents can be avoided; and sparks generated by mechanical collision are avoided, so that the maintenance safety is improved.

The utility model relates to noise protection equipment technical field, specifically disclose a kind of spliced anti-falling sound barrier, including support rod, rolling ball, limit block and height adjusting part, the double limit of rolling ball is realized by trapezoidal block and rolling groove in limit block and utilizes the rolling effect of rolling ball to buffer, prevent sound barrier from falling;Adjacent limit block is fixed using screw rod, and quick splicing is realized;Scissor type telescopic stand is adjusted height in cooperation with guide slide, the design has the advantages of convenient installation, high stability, strong adaptability etc., is applicable to the place, such as road, bridge, and needs the place of noise reduction.

The utility model discloses a palletizing device for palletizing rust removers in barrels, and belongs to the technical field of palletizing devices. A rust remover barrel stacking device comprises a stacking upper frame, guide rods are symmetrically arranged on the inner wall of the stacking upper frame, sliding seats are symmetrically arranged on the surfaces of the guide rods in a sliding mode, a semicircular clamping frame is arranged between the two sliding seats and used for clamping, and locking springs are arranged on the back faces of the sliding seats. According to the rust remover barrel clamping device, rust remover barrels with different diameters can be effectively clamped through the sliding connection of the semicircular clamping frame on the guide rod through the sliding seat and the elastic force effect of the locking spring. By means of the design, the stability of the rust remover barrels in the stacking process is guaranteed, and potential safety hazards caused by shaking or inclining are avoided. And meanwhile, protection pads are arranged on the inner sides of the semicircular clamping frames, so that clamping protectiveness is further enhanced, and the situation that the surface of the rust remover barrel is damaged due to clamping is effectively prevented.

The utility model relates to the technical field of trundles, in particular to a foot-stepping rapid lifting and moving trundle which comprises a lifting pipe base and a small lifting pipe inserted into the lifting pipe base and connected with the lifting pipe base in a sliding mode, and further comprises a lifting pedal rotationally connected with the lifting pipe base through a bolt A; one end of the rotary driving seat is hinged to the lifting pedal through a bolt C, and the other end of the rotary driving seat is hinged to the small lifting pipe through a bolt D; the fallback pedal is rotationally connected with the lifting pipe base through the bolt A; according to the foot-treading rapid lifting and moving trundle, the one-key lifting and one-key falling functions are achieved through the double-pedal design, a user can finish height adjustment and unlocking only by treading, and time and labor are saved.

The utility model discloses a steel box girder pushing guiding device, and relates to the field of steel box girder guiding devices, the steel box girder pushing guiding device comprises two groups of guiding abutting devices which have the same structure and are symmetrically arranged, and a single group of guiding abutting devices comprises a fixed base which is provided with a supporting seat; the first driving part is arranged on the fixed base; the supporting arm is vertically arranged on the supporting seat; the rotating arm is rotationally arranged at one end, far away from the supporting seat, of the supporting arm; the mounting frame is rotationally arranged at the end, away from the supporting arm, of the rotating arm, and a guide ball is arranged on the mounting frame; the height adjusting assembly is arranged on the supporting seat and used for controlling the rotating arm to rotate in the height direction of the steel box girder; and the angle adjusting assembly is arranged on the rotating arm and used for controlling the mounting frame to move in the length direction of the steel box girder. The technical problem that in the prior art, due to the fact that the same guiding device is difficult to adapt to steel box girders of different forms, the guiding efficiency of the steel box girders is low is solved.
