4results about How to "Increase vertical stiffness" patented technology

The application provides a vehicle. It belongs to the technical field of vehicles. The vehicle comprises a vehicle body frame, which comprises: a frame beam body having a first side facing the inside of the vehicle body and a second side facing the outside of the vehicle body, the frame beam body being formed with a groove recessed towards the second side; a first reinforcing column at least partially filling the first side of the groove of the frame beam body; a connecting piece, at least part of the connecting piece being arranged in the first reinforcing column along the inside-outside direction of the vehicle body and connected with the first reinforcing column; a door hinge connected with a door; and a fastening assembly comprising a first fastener and a second fastener, the door hinge being connected with the connecting piece through the first fastener and the second fastener. Thus, the vertical rigidity of the door can be improved.

The utility model relates to tool room building structure technical field, and disclose a kind of roof beam eave structure of tool room, including the first plate body and second plate body being connected with each other, the second plate body is equipped with recess, top end portion is equipped on the first plate body, its top end portion has the profile form that can guide top load to both sides dispersion conduction, and the first plate body and the second plate body with recess form the overall framework of collaborative stress, the first plate body and second plate body cooperation structure are connected with the connecting structure of tool room board assembly, the utility model is dispersed by the profile form of top end portion on the first plate body to guide top load, in combination with the deformation buffer of second plate body recess, form collaborative stress framework, effectively reduce local stress concentration, its support plate enhances vertical rigidity, double support plate symmetric distribution and open space design improve load dispersion and buffer capacity, and the joint plate strengthens the inclination end cooperativity, slot realizes board fast and stable assembly, adaptive modularization builds demand.

This invention discloses a prefabricated steel-concrete composite bridge structure for use in high-altitude and cold regions, relating to the field of bridge structure technology. The technical solution includes a bridge deck with side beams inside. Each side beam has a drainage cavity. A water-passing filter plate is fixedly connected to the upper part of the drainage cavity. A pressure block is slidably connected to the upper part of the side beam near the water-passing filter plate. A second rack is fixedly connected to the bottom of the pressure block. The second rack is meshed with a first gear. The first gear is fixedly connected to a second gear, which in turn meshes with the first rack. In this invention, the drainage cavity effectively drains melted snow water into the drainage trough through a pipe, effectively preventing the accumulation of melted snow water in high-altitude and cold regions. When a vehicle passes over the side beam, the wheel presses down on the pressure block, causing the second rack to move. This movement of the second rack causes the first rack to move, impacting one side of the water-passing filter plate and causing it to vibrate, dislodging sand and gravel adhering to the filter holes on the surface of the water-passing filter plate.

The application provides a reinforced railway turnout bonding insulation joint clamp plate and a manufacturing method thereof. The clamp plate comprises a clamp plate body, one side of the clamp plate body is a working surface, and the other side is a non-working surface. The working surface is similar to a fish tail space of a steel rail. The non-working surface is provided with a clamp plate reinforcing rib. The clamp plate reinforcing rib comprises upper and lower transverse reinforcing ribs and a vertical reinforcing rib which is connected to the upper and lower transverse reinforcing ribs from a midpoint. The non-working surface is also provided with a clamp plate top surface which has an L-shaped structure at the top and an inner recess interference structure at the bottom. The inner recess interference structure is arranged on the left and right sides of the lower transverse reinforcing rib. A plurality of clamp plate bolt through holes are symmetrically arranged along the longitudinal center line of the clamp plate body. The through hole position is coincided with the joint hole position of the steel rail which is matched with the clamp plate. The application improves the fatigue performance, eliminates the interference hidden danger in the field laying, has good universality, and guarantees the stability and safety of train driving. The manufacturing method adopts a rolling process, and the material utilization rate is not less than 90%. The method has good machinability and processability.
