Description

Technical Field

[0001] This application belongs to the field of coal mine roadway support technology, specifically a coal mine roadway excavation safety support device. Background Technology

[0002] Coal mine tunneling support devices are support equipment specifically designed for coal mine roadway tunneling operations. Their main purpose is to ensure the stability of the roadway under complex geological conditions, prevent safety accidents such as roof collapse and coal wall spalling during tunneling, and ensure the safety of workers.

[0003] For example, application CN221568528U discloses a coal mine tunneling support device, mainly relating to the field of coal mine tunneling support equipment. A coal mine tunneling support device includes a U-shaped plate, with connecting plates on both bottom sides of the U-shaped plate. Each connecting plate has a groove on its top surface, and a connecting block is installed in each groove via a first telescopic rod. The top surface of each connecting plate is connected to the bottom end of the U-shaped plate. An arc-shaped support plate is installed on the top surface of the U-shaped plate, and rollers are installed on the bottom surface of each connecting plate. The advantages of this utility model are: the utility model has a simple structure and is easy to use. Through the cooperation of the first telescopic rod and the U-shaped plate, the height of the arc-shaped support plate can be adjusted, allowing the arc-shaped support plate to contact and support the top of the roadway, thus meeting the usage needs of roadways at different heights. Furthermore, the rolling motion allows the device to move, providing support at different locations, thus facilitating use.

[0004] However, during the implementation of this application, it was discovered that when multiple devices need to be spliced ​​together, there is a lack of connecting devices between individual devices. In addition, the bottom of the rollers is in direct contact with the ground after being fixed, which makes it easy to shake during use and affects the stability during use. Utility Model Content

[0015] By adopting the above technical solution, the contact area is further increased, and the stability of the overall device during use is improved.

[0016] As a further description of the above technical solution, a plurality of LED lights are fixedly installed on the lower surface of the supporting cross plate.

[0017] By adopting the above technical solution, the lighting brightness is improved and the safety of the overall device during use is increased.

When multiple lifting bases and lifting rods need to be spliced ​​together, the plug-in magnetic fixing head is inserted into the interior of the matching plug-in groove. Then, the plug-in magnetic fixing head and the magnetic connecting piece are attracted and fixed to each other. The anti-sway plug-in protrusion is inserted into the interior of the anti-sway plug-in base. Then, the plug-in magnetic fixing head is fixed by tightening the fastening threaded rod. This allows multiple devices to be connected into a whole when spliced, improving the stability of the connection. At the same time, the use of the anti-sway plug-in protrusion and the anti-sway plug-in base also minimizes the instability of the overall device during use, so that it will not easily shake.

Then, the plug-in magnetic fixing head 8 and the magnetic connecting piece 12 are attracted and fixed to each other. The anti-sway plug-in protrusion 10 is inserted into the interior of the anti-sway plug-in base 13. Then, the plug-in magnetic fixing head 8 is fixed by tightening the fastening threaded rod 14. Thus, multiple devices can be connected into a whole when spliced, which improves the stability of the connection. At the same time, the use of the anti-sway plug-in protrusion 10 and the anti-sway plug-in base 13 also minimizes the stability of the overall device during use, so that it will not easily shake. The bottom of the lifting base 1 is equipped with an adjusting threaded rod 21.
