Recently, it was reported that information from the State Intellectual Property Office showed that a patent jointly applied by four companies titled “A reprinter chute with a support function” was authorized.
The patent authorization announcement number is CN224363989U, the authorization announcement date is June 16, 2026, the application number is CN202521856905.9, and the application date is August 29, 2025.

The patent summary shows that the transfer machine chute with support function includes a number of telescopic gantry frames, a number of telescopic anchor post assemblies, a number of first tank bodies and a number of second tank bodies, and a number of first tank bodies and several second tank bodies are spliced together.
The telescopic gantry spans over the first tank body and is used to provide overall support to the top of the first tank body; the telescopic anchor post assembly is ball-jointed on both sides of the second tank body and is used to perform split support according to the terrain of the tunnel roof at the top of the second tank body.
This design improves the support capacity of the tunnel directly above the transfer machine tank and improves the applicability to the terrain of the tunnel roof.
Companies participating in this patent application include a large energy company, a medium-sized software and information technology services company, and two large-scale special-purpose and general-purpose equipment manufacturing companies.
The large-scale energy company was established in 2002. Its industry is petroleum, coal and other fuel processing industries, and the scale of the company is large.
The company has invested in 47 foreign companies, participated in 128,358 bidding projects, and has rich trademark information and patent information.
Recently, the company has obtained patent results in many fields, covering many aspects such as rosin air-entraining agents, cross-lane support structures, and manned devices for confined spaces.

A medium-sized software and information technology service company was established in 2009. It has many patented achievements in scraper conveyor-related technologies, such as scraper conveyor conveyor conveying capacity calculation methods and testing devices, scraper conveyor sprocket wear degree monitoring methods and devices, etc.
The other two large enterprises were established in 2002 and 2020 respectively, and their industries are special equipment manufacturing and general equipment manufacturing respectively.
They also have many patents on coal mining equipment and related technologies, covering hydraulic supports, mining machines, tunnel boring machines and other fields.
The patent for the transfer machine chute jointly obtained by the four companies this time is a reflection of the integration of the technical advantages of all parties.
It not only provides a more effective solution for tunnel support, but also demonstrates the company’s active exploration in technological innovation.
With the continuous development of science and technology, I believe these companies will make breakthroughs in more fields and make greater contributions to the development of the industry.
