A hopper bottom door unit mounted to a hopper body (200) of a hopper (1000), the hopper body (200) of the hopper (1000) being provided with a discharge opening. The hopper bottom door unit (100) comprises: a bottom door mechanism (110), which is mounted to the hopper body (200) and has a shielding position in which the discharge opening is shielded and an open position in which the discharge opening is exposed; a door closing drive assembly (120), which is mounted to the hopper body (200) and connected to the bottom door mechanism (110), and is configured to drive the bottom door mechanism (110) to move to enable the bottom door mechanism (110) to be located at the shielding position; and a door opening drive assembly (130), which is mounted to the hopper body (200) and connected to the bottom door mechanism (110), and is configured to drive the bottom door mechanism (110) to move to enable the bottom door mechanism (110) to be located at the open position.

This invention provides a hook-type wedge key anti-loosening mechanism for railway hopper cars and a railway hopper car, relating to the field of railway vehicle technology. It is used for anti-loosening connection of a hook-type wedge key between a drive shaft and a crank, comprising: a first threaded hole provided on one end face of the drive shaft near the hook-type wedge key; a lever with a through hole in the middle of its side, wherein when the center line of the through hole coincides with the center line of the first threaded hole, the lower part of the lever can fit against the exposed end of the hook-type wedge key; and a first bolt, one end of which can pass through the through hole and be threadedly connected to the first threaded hole. This mechanism has a simple structure, requiring only the operation of the first bolt on the lever during assembly and disassembly. It involves fewer assembly and disassembly steps, is highly efficient, and economical. It solves the problems of numerous steps, low efficiency, and high manufacturing and repair costs associated with existing railway hopper car technologies using stop welding and disassembly, thereby improving traffic safety.

A launcher for a zipline trolley system comprises a body, first and second arms, first and second connectors, first and second pads, and an actuating portion. The first and second arms extend from the body. The first and second connectors are pivotably connected to the first and second arms, respectively. The first and second pads are connected to the first and second connectors, respectively. The actuating portion comprises a sliding member and first and second pull arms. The first and second pull arms are connected to the first and second connectors, respectively. When the launcher is in a first configuration, the first and second pads are adapted to hold the trolley in place. Movement of the sliding member away from the body causes pivotable movement of the first and second connectors and a transition of the launcher to a second configuration to release the trolley.

The utility model relates to the technical field of stone residue hopper car, concretely to a hopper car convenient for stone residue loading and unloading, including bottom plate and the carriage of setting on bottom plate, the bottom end of hopper is connected with the hopper, and the bottom end of hopper is penetrated through bottom plate and is equipped with the discharge port for discharging, bottom plate below is provided with the cover plate part and the pressing plate part that close the opening, the pressing plate part is connected with the extension part, this hopper car convenient for stone residue loading and unloading, through setting the extension part on the pressing plate part, can lengthen the length of hopper plate, namely the movement stroke of material when discharging, so that material can be unloaded in the place far away from hopper car and track, to adapt to the actual construction working condition and the actual demand of different unloading site.

The utility model discloses a kind of bottom opening door wide rail car box rolling type limiting structures, including the car box loaded with container, the four corners of the car box and the four corners of the opposite end of two groups of the container are evenly provided with limiting unit, the limiting unit includes the sliding track vertically installed on the inner wall of the car box, two groups of contact roller and buffer unit installed on mounting plate;The mounting plate is slidably arranged on the sliding track by sliding block;Two groups of the contact roller are installed on the mounting plate by L-shaped rod, and two groups of the contact roller are vertically arranged.Contact roller's elastic buffer layer, buffer spring synergistic effect, the rigid collision of traditional limiting block is converted into elastic buffer, effectively reduce the damage to container;And contact roller rolling contact, have good impact unloading effect, also reduce friction and abrasion, compared with limiting block, use contact roller can greatly improve the service life of the limiting structure and container.

A system having a railcar with a first hopper spaced longitudinally from a second hopper and a panel assembly spanning between the first hopper and the second hopper and configured to reduce aerodynamic drag caused by air turbulence generated by movement of the railcar. The panel assembly includes a panel portion and a frame. The panel portion may have a perimeter edge defining a generally trapezoidal shape. The frame may have a plurality of frame members engaged along sections of the perimeter edge of the panel portion. The frame may also include a first slot configured to movably engage an attachment feature on the first hopper and a second slot configured to movably engage an attachment feature on the second hopper.

Interface wagon (1; 1a, 1b) for a work train (100), configured to receive a granular product (P) loaded from a public works machine (E;Ea, Eb), comprising: - a chassis (2) comprising a frame (4) elongated along a longitudinal axis (X) of the interface wagon (1) between two longitudinal ends (5), and bogies (6) supporting said frame (4), - a first belt conveyor (10) arranged on the frame (4) of the chassis (2) and configured to circulate the granular product (P) along the longitudinal axis (X), - an inclined boom (11) arranged near one of the longitudinal ends (5) of the frame (4) and - a second belt conveyor (12) arranged on the boom (11) and configured to circulate the granular product (P) from one end (19) of the first belt conveyor (10) to the top of the boom (11) so as to allow the granular product (P) to be discharged into an adjacent wagon in which the frame (4) comprises two side walls (14) surrounding the first belt conveyor (10) and configured to receive the loading of granular product (P).;
