6results about How to "Prevent stuck situations" patented technology

This utility model discloses a CNC machining feeding device, relating to the field of machining feeding technology. It includes a conveying assembly, with a support frame fixedly connected to the top of the conveying assembly. An insertion slot is provided inside the support frame, and an insertion plate is inserted into the insertion slot. A connecting plate is fixedly connected to the side of the insertion plate. By providing the support frame and insertion plate, this utility model allows workpieces to pass through the conveyor belt individually and orderly during use. This ensures accurate positioning when entering the machining station, avoids clamping offset caused by stacking, and guarantees the accuracy of machining dimensions and hole positions. The device also includes a rotating roller and a rotating shaft, which protect the outer surface of the passing workpieces during use, effectively preventing scratches and guiding the workpieces to prevent them from getting stuck under the insertion plate.

The application provides a nut assembly and an electronic expansion valve, and the nut assembly comprises: a nut body, the nut body is provided with an internal thread, and the outer circumferential surface of the nut body is provided with a spiral guide groove; a stop ring, the stop ring is arranged on the spiral guide groove, and the stop ring is rotatably arranged along the spiral guide groove; a first limiting structure, the first limiting structure is arranged on the nut body, the first limiting structure is provided with a first stop surface protruding from the outer circumferential surface of the nut body, and the stop ring and the first stop surface are in stop cooperation; a second limiting structure, the second limiting structure is arranged on the nut body, the second limiting structure is provided with a second stop surface protruding from the outer circumferential surface of the nut body, and the stop ring and the second stop surface are in stop cooperation; wherein the spiral guide groove is located between the first limiting structure and the second limiting structure. By adopting the scheme, the stop position between the stop ring and the first stop surface and the second stop surface is prevented from being located in the spiral guide groove or on the extension line of the spiral guide groove, and the reliability of the movement of the stop ring is ensured.

The application provides a control method of a coal cutter towline trolley, which is executed by a towline control system, the system comprising a towline controller arranged in a machine head roadway, a self-driven towline trolley arranged on a scraper, and a cable reel arranged at a machine tail side; the method comprising the following steps: the towline controller acquires a first operation parameter from the coal cutter, a second operation parameter from the self-driven towline trolley, and a third parameter reflecting the state of a cable clamp plate; the towline controller generates a control instruction based on the first operation parameter, the second operation parameter, and the third parameter and sends the control instruction to the self-driven towline trolley to control the operation speed and direction of the self-driven towline trolley, so that the self-driven towline trolley is kept in synchronous motion with the coal cutter and the cable clamp plate is kept in a preset stacking state. The control method of the application can effectively adapt to the bending deformation of the scraper, realizes intelligent control based on multi-source information, has a safety protection function, and improves the reliability, safety, and automation level of the towline system.

The utility model discloses a rail type snow sweeping robot, which belongs to the technical field of photovoltaic module sweeping, and comprises a rail, a driving mechanism, a bearing mechanism, a cleaning mechanism and a butt joint mechanism, when the cleaning mechanism needs to be moved from a ferry vehicle to a photovoltaic panel, a sliding block is fixedly connected to a mounting plate of the butt joint mechanism, and the sliding block is fixedly connected to the mounting plate of the butt joint mechanism; a telescopic assembly is arranged on the sliding block, a butt joint block is arranged at the telescopic end of the telescopic assembly, the butt joint block can be driven to be pre-aligned with a bearing assembly on the photovoltaic panel through the telescopic assembly, and when the butt joint block cannot be aligned with the bearing assembly on the photovoltaic panel, it is indicated that the photovoltaic panel shifts. The cleaning mechanism and the butt joint mechanism integrally return to the bearing mechanism along the original path, and the driving mechanism moves to clean the next row of photovoltaic panels, so that the situation that the cleaning mechanism is stuck due to displacement of the photovoltaic panels when the photovoltaic panels move can be effectively prevented, and the working efficiency of the device can be ensured.

The utility model provides a kind of power plant chimney maintenance platform anti-falling and emergency buffer safety mechanism, it is related to maintenance platform technical field, comprising: maintenance platform main part, the maintenance platform main part is encased on power plant chimney, and maintenance platform main part below is equipped with climbing ladder, and climbing ladder fixed mounting is on power plant chimney side wall;Maintenance platform main part below is equipped with track assembly, by lower track and upper track and rolling wheel interwork, moving frame can drive second safety rope to move, to adjust second safety rope position according to actual condition, maintenance personnel fall to ground through second safety rope urgently, ensure that personnel quickly and safely evacuate, solve the existing power plant chimney maintenance platform when using, usually utilize climbing ladder to go up and down platform, if emergency maintenance personnel cannot use climbing ladder to reach ground, lead to unable to quickly escape dangerous environment, there is certain security risk problem.

The utility model relates to clothes processing technical field, concretely provides a thread scrap collecting device and clothes processing equipment, concretely, the thread scrap collecting device of the utility model includes shell, filter component and scraping mechanism, the first end of shell has the air inlet, the first end and the second end between have the air outlet, filter component installs at the air outlet, scraping mechanism can move along the first direction to the first end of shell to push the thread scrap in the shell to move to the air inlet, be provided with the rolling component on scraping mechanism, and the rolling component is contacted with the shell to make scraping mechanism can move smoothly relative to shell. Push the thread scrap to move to the air inlet through scraping component, it is convenient for the cleaning thread scrap, is favorable to the improvement thread scrap's cleaning efficiency, and, through setting up the rolling component on scraping mechanism and rolling along the shell, can reduce the friction between scraping mechanism and shell, make scraping mechanism move more smoothly, and user operation is more labor-saving, and the use experience is better.
