This utility model discloses a support frame for safe production in coal mines, including two symmetrically arranged bases. Hydraulic supports are fixedly mounted on the upper surfaces of both bases, and a lifting plate is fixedly mounted between the upper ends of the hydraulic supports. A bearing plate is fixedly mounted on the upper surface of the lifting plate. Side guard plates are hinged to both sides of the bearing plate, and an arc-shaped buffer assembly connects the bottom surface of the side guard plates and the bottom surface of the bearing plate. A top guard plate is connected to the upper surface of the bearing plate via four sets of cross-shaped buffer mechanisms. This utility model effectively protects against falling rocks by hinged side guard plates on both sides of the bearing plate and the installation of arc-shaped buffer assemblies. The top guard plate is connected to the upper surface of the bearing plate via four sets of cross-shaped buffer mechanisms. The slider in the buffer mechanism can slide on the slide rod, and in conjunction with the springs on both sides, effectively absorbs and disperses the impact force when the top surface is impacted by falling rocks, preventing the impact force from directly acting on the support frame and preventing damage to the support frame due to excessive force.

This utility model relates to an anti-loosening device for a high-voltage bushing end screen, comprising an outer casing, a bushing end screen unit, a conductive rod, an anti-loosening unit, and a top cover. The bushing end screen unit, conductive rod, and anti-loosening unit are all installed within the outer casing. The bushing end screen unit is connected to the anti-loosening unit via the conductive rod. The top cover is installed on the outer casing, and the anti-loosening unit is installed on a fixed cover. This utility model forms an elastic pre-tightening system between the outer casing end screen unit, the conductive rod, and the anti-loosening unit. The conductive rod transmits the vibration of the bushing end screen unit, and the anti-loosening unit dynamically adapts to changes in the displacement of the conductive rod, ensuring good contact between the three components.

This utility model discloses a plastic-coated steel pipe bend joint suitable for low-temperature conditions, comprising a bend section and straight pipe sections welded to both ends, forming a bend structure. It also includes: a stress buffer device comprising a corrugated compensator welded to the junction of the bend section and the straight pipe section, and a flow-damping orifice plate connected to the other end face of the corrugated compensator; and a damping sliding pair comprising a damping sliding tube fixed to the outer wall of the flow-damping orifice plate and a fixed damping kit fitted into the inner wall of the straight pipe section. The end face of the corrugated compensator connected to the flow-damping orifice plate is a free end that slides axially along the straight pipe section, and the damping sliding tube and the fixed damping kit achieve a sliding seal through an elastic seal. This utility model uses the sealing gas, the elastic material in the corrugated compensator, and the friction generated by the relative sliding of the damping sliding tube and the fixed damping kit to jointly counteract the pressure caused by frost heave, making the joint fully adaptable to low-temperature conditions.

This utility model discloses a radiator mounting mechanism, comprising: a support positioning platform for positioning the radiator module and a snap-fit ​​assembly mechanism for installing snap-fit ​​rings. The snap-fit ​​assembly mechanism includes a first support frame, a lifting seat mounted on the first support frame and suspended above the support positioning platform, at least one base plate horizontally mounted on the lifting seat, a stacking plate vertically mounted on the lifting seat for stacking snap-fit ​​rings, a pusher plate slidably mounted on the base plate for pushing the snap-fit ​​rings at the lower end of the stacking plate, a first cylinder mounted at one end of the base plate for driving the pusher plate, and a second cylinder mounted on the first support frame for driving the lifting seat. The support positioning platform positions the radiator module below the snap-fit ​​assembly mechanism. The snap-fit ​​assembly mechanism descends and presses against the radiator module. Multiple first cylinders push the pusher plate to simultaneously snap multiple snap-fit ​​rings onto the radiator module, completing the assembly of the radiator module.
