Locking Mechanisms For Points TRIZ Cases

A rail switch checking device uses a lever mechanism to convert linear rod movement into compact output motion for precise end position detection.

Control unit automates locking rod positioning to eliminate manual screw connections and reduce personnel effort on construction sites.

A decoupled actuator mediates driver motion to detect negative play in locking recesses, enabling mechanical calibration of the measurement unit.

A universal pawl lock unit with a cam bar moves railway switch blades, reducing development costs across varying track gauges.

Segmented switch stands and nested connecting rod housings prevent damage from track debris while enabling independent central point locking.

Segmenting the slide rod into two cams prevents switch blade deviation and jamming caused by temperature migration and friction wear.

An articulated coupling assembly with a spherical sliding seat compensates for thermal expansion and removes residues, reducing fretting wear in switch points.

Anti-rotation ring aligns locking bearing screw head to prevent adjusting tongue twisting under high torque.

Segmented spring steel securing element prevents loosening of tongue attachment screws and retaining clamps against contamination.

Segmenting the hollow screw into separate body and head components distributes stress via conical fitting, reducing breakage by 50%.

A segmented H-shaped coupling prevents wedge loosening under operational loads, ensuring stable tongue block fixation.

A locking pin engages a socket spanner pocket to secure sliding bodies on guide tracks without external attachments.

A pawl lock uses a displaceable plate to adjust the switch tongue position relative to the bearing without shifting the pivot point.

Segmented support structure releases sliding fur laterally, eliminating the need to dismantle the locking arm during maintenance.

Segmented sensors measure movable railway element positions to resolve the trade-off between measurement precision and device complexity.

Lateral mounting of a parallelepipedal locking part aligns contact and bearing surfaces to transmit stress directly to the frame, preventing ruptures.

A leaf spring linked to a roller on a cam stabilizes the locking arm position in railway switch mechanisms.

Adjustable locking stamp reduces storage needs by replacing multiple fixed lengths with a single versatile component.

A toggle assembly deforms a spring-loaded elastic element to snap open the circuit, reducing arcing and ensuring reliable shut-off in railroad environments.

Independent control rods detect switch point disengagement by preventing the locking group from engaging unless both rods reach predetermined positions.

A rail claw mounts a contactless sensor to measure the spatial position of movable railway elements without mechanical interference.

A railroad switch safety device monitors control tie-rod positions to detect unsynchronized translation during operation.
